• What happened to .fx files in D3D11?

  - by bobobobo

  It seems they completely ruined .fx file loading / parsing in D3D11. In D3D9, loading an entire effect file was D3DXCreateEffectFromFile( .. ), and you got a ID3DXEffect9, which had great methods like SetTechnique and BeginPass, making it easy to load and execute a shader with multiple techniques. Is this completely manual now in D3D11? The highest level functionality I can find is loading a SINGLE shader from an FX file using D3DX11CompileFromFile. Does anyone know if there's an easier way to load FX files and choose a technique? With the level of functionality provided in D3D11 now, it seems like you're better off just writing .hlsl files and forgetting about the whole idea of Techniques.

• Map and fill texture using PBO (OpenGL 3.3)

  - by NtscCobalt

  I'm learning OpenGL 3.3 trying to do the following (as it is done in D3D)... Create Texture of Width, Height, Pixel Format Map texture memory Loop write pixels Unmap texture memory Set Texture Render Right now though it renders as if the entire texture is black. I can't find a reliable source for information on how to do this though. Almost every tutorial I've found just uses glTexSubImage2D and passes a pointer to memory. Here is basically what my code does... (In this case it is generating an 1-byte Alpha Only texture but it is rendering it as the red channel for debugging) GLuint pixelBufferID; glGenBuffers(1, &pixelBufferID); glBindBuffer(GL_PIXEL_UNPACK_BUFFER, pixelBufferID); glBufferData(GL_PIXEL_UNPACK_BUFFER, 512 * 512 * 1, nullptr, GL_STREAM_DRAW); glBindBuffer(GL_PIXEL_UNPACK_BUFFER, 0); GLuint textureID; glGenTextures(1, &textureID); glBindTexture(GL_TEXTURE_2D, textureID); glTexImage2D(GL_TEXTURE_2D, 0, GL_R8, 512, 512, 0, GL_RED, GL_UNSIGNED_BYTE, nullptr); glBindTexture(GL_TEXTURE_2D, 0); glBindTexture(GL_TEXTURE_2D, textureID); glBindBuffer(GL_PIXEL_UNPACK_BUFFER, pixelBufferID); void *Memory = glMapBuffer(GL_PIXEL_UNPACK_BUFFER, GL_WRITE_ONLY); // Memory copied here, I know this is valid because it is the same loop as in my working D3D version glUnmapBuffer(GL_PIXEL_UNPACK_BUFFER); glBindBuffer(GL_PIXEL_UNPACK_BUFFER, 0); And then here is the render loop. // This chunk left in for completeness glUseProgram(glProgramId); glBindVertexArray(glVertexArrayId); glBindBuffer(GL_ARRAY_BUFFER, glVertexBufferId); glEnableVertexAttribArray(0); glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 20, 0); glVertexAttribPointer(0, 2, GL_FLOAT, GL_FALSE, 20, 12); GLuint transformLocationID = glGetUniformLocation(3, 'transform'); glUniformMatrix4fv(transformLocationID , 1, true, somematrix) // Not sure if this is all I need to do glBindTexture(GL_TEXTURE_2D, pTex->glTextureId); GLuint textureLocationID = glGetUniformLocation(glProgramId, "texture"); glUniform1i(textureLocationID, 0); glDrawArrays(GL_TRIANGLES, Offset*3, Triangles*3); Vertex Shader #version 330 core in vec3 Position; in vec2 TexCoords; out vec2 TexOut; uniform mat4 transform; void main() { TexOut = TexCoords; gl_Position = vec4(Position, 1.0) * transform; } Pixel Shader #version 330 core uniform sampler2D texture; in vec2 TexCoords; out vec4 fragColor; void main() { // Output color fragColor.r = texture2D(texture, TexCoords).r; fragColor.g = 0.0f; fragColor.b = 0.0f; fragColor.a = 1.0; }

• What is the best type of c# timer to use with an Unity game that uses many timers simultaneously?

  - by Kyle Seidlitz

  I am developing a stand-alone 3d game in Unity that will have anywhere from 1 to 200 timers running simultaneously. For this game timer durations will range from 5 minutes to 4 days. There will not be any countdown displays or any UI for the timers. An object will be selected, a menu choice will then be selected, and the timer will start. Several events will occur at different intervals during the duration of the timer. The events will be confined to changing the material of the selected object, and calling a 1 second sound effect like a chime or a bell. If the user wants to save or end the game before all the timers are done, the start of the still running timers is to be saved to an XML file such that when the game is started again, any still running timers will have a calculation done to see if the timer is then done, where the game will change the materials appropriately. I am still trying to figure out what type of timer to use, and see also if there are any suggestions for saving and calculating times over several days. What class(es) of timers should I use? Are there any special issues I should look out for in terms of performance?

• How can I resolve component types in a way that supports adding new types relatively easily?

  - by John

  I am trying to build an Entity Component System for an interactive application developed using C++ and OpenGL. My question is quite simple. In my GameObject class I have a collection of Components. I can add and retrieve components. class GameObject: public Object { public: GameObject(std::string objectName); ~GameObject(void); Component * AddComponent(std::string name); Component * AddComponent(Component componentType); Component * GetComponent (std::string TypeName); Component * GetComponent (<Component Type Here>); private: std::map<std::string,Component*> m_components; }; I will have a collection of components that inherit from the base Components class. So if I have a meshRenderer component and would like to do the following GameObject * warship = new GameObject("myLovelyWarship"); MeshRenderer * meshRenderer = warship->AddComponent(MeshRenderer); or possibly MeshRenderer * meshRenderer = warship->AddComponent("MeshRenderer"); I could be make a Component Factory like this: class ComponentFactory { public: static Component * CreateComponent(const std::string &compTyp) { if(compTyp == "MeshRenderer") return new MeshRenderer; if(compTyp == "Collider") return new Collider; return NULL; } }; However, I feel like I should not have to keep updating the Component Factory every time I want to create a new custom Component but it is an option. Is there a more proper way to add and retrieve these components? Is standard templates another solution?

• Making large scale changes to an economy in a social game

  - by Zach

  Are there any examples or case studies of social games, specifically on Facebook, where the developer has made drastic changes to the economy? I'm specifically interested in examples where the old economy was based off of purchasing items with Facebook credits then moving to a new model where the same inventory or similar inventory is sold with a soft currency. The closest comparisons I've been able to find so far are looking at iOS games that have gone from purchase models to freemium models, but haven't found a comparable scenario in a social game besides larger scale MMO's.

• XNA texture stretching at extreme coordinates

  - by Shaun Hamman

  I was toying around with infinitely scrolling 2D textures using the XNA framework and came across a rather strange observation. Using the basic draw code: spriteBatch.Begin(SpriteSortMode.Deferred, null, SamplerState.PointWrap, null, null); spriteBatch.Draw(texture, Vector2.Zero, sourceRect, Color.White, 0.0f, Vector2.Zero, 2.0f, SpriteEffects.None, 1.0f); spriteBatch.End(); with a small 32x32 texture and a sourceRect defined as: sourceRect = new Rectangle(0, 0, Window.ClientBounds.Width, Window.ClientBounds.Height); I was able to scroll the texture across the window infinitely by changing the X and Y coordinates of the sourceRect. Playing with different coordinate locations, I noticed that if I made either of the coordinates too large, the texture no longer drew and was instead replaced by either a flat color or alternating bands of color. Tracing the coordinates back down, I found the following at around (0, -16,777,000): As you can see, the texture in the top half of the image is stretched vertically. My question is why is this occurring? Certainly I can do things like bind the x/y position to some low multiple of 32 to give the same effect without this occurring, so fixing it isn't an issue, but I'm curious about why this happens. My initial thought was perhaps it was overflowing the coordinate value or some such thing, but looking at a data type size chart, the next closest below is an unsigned short with a range of about 32,000, and above is an unsigned int with a range of around 2,000,000,000 so that isn't likely the cause.

• How to manage my model

  - by Christophe Debove

  I have in my model, a list of Classes : Player, NonPlayerCharacter, Monster, Item, NonMovableItem etc With AndEngine I've a list of sprite for each piece of my model, How can I manage the relashionship between my model's classes and the graphical elements, what is the degree of abstaction recommended for my problem? One sprite for one Model or one Model for one Sprite or n for n for exemple If I do drag&drop have I to make abstraction of the Sprite Class, another exemple a map is a List of sprite or a list of element of my model?

• More Efficient Data Structure for Large Layered Tile Map

  - by Stupac

  It seems like the popular method is to break the map up into regions and load them as needed, my problem is that in my game there are many AI entities other than the player out performing actions in virtually all the regions of the map. Let's just say I have a 5000x5000 map, when I use a 2D array of byte's to render it my game uses around 17 MB of memory, as soon as I change that data structure to a my own defined MapCell class (which only contains a single field: byte terrain) my game's memory consumption rockets up to 400+ MB. I plan on adding layering, so an array of byte's won't cut it and I figure I'd need to add a List of some sort to the MapCell class to provide objects in the layers. I'm only rendering tiles that are on screen, but I need the rest of the map to be represented in memory since it is constantly used in Update. So my question is, how can I reduce the memory consumption of my map while still maintaining the above requirements? Thank you for your time! Here's a few snippets my C# code in XNA4: public static void LoadMapData() { // Test map generations int xSize = 5000; int ySize = 5000; MapCell[,] map = new MapCell[xSize,ySize]; //byte[,] map = new byte[xSize, ySize]; Terrain[] terrains = new Terrain[4]; terrains[0] = grass; terrains[1] = dirt; terrains[2] = rock; terrains[3] = water; Random random = new Random(); for(int x = 0; x < xSize; x++) { for(int y = 0; y < ySize; y++) { //map[x,y] = new MapCell(terrains[random.Next(4)]); map[x,y] = new MapCell((byte)random.Next(4)); //map[x, y] = (byte)random.Next(4); } } testMap = new TileMap(map, xSize, ySize); // End test map setup currentMap = testMap; } public class MapCell { //public TerrainType terrain; public byte terrain; public MapCell(byte itsTerrain) { terrain = itsTerrain; } // the type of terrain this cell is treated as /*public Terrain terrain { get; set; } public MapCell(Terrain itsTerrain) { terrain = itsTerrain; }*/ }

• Deferred Rendering With Diffuse,Specular, and Normal maps

  - by John

  I have been reading up on deferred rendering and I am trying to implement a renderer using the Sponza atrium model, which can be found here, as my sandbox.Note I am also using OpenGL 3.3 and GLSL. I am loading the model from a Wavefront OBJ file using Assimp. I extract all geometry information including tangents and bitangents. For all the aiMaterials,I extract the following information which essentially comes from the sponza.mtl file. Ambient/Diffuse/Specular/Emissive Reflectivity Coefficients(Ka,Kd,Ks,Ke) Shininess Diffuse Map Specular Map Normal Map I understand that I must render vertex attributes such as position ,normals,texture coordinates to textures as well as depth for the second render pass. A lot of resources mention putting colour information into a g-buffer in the initial render pass but do you not require the diffuse,specular and normal maps and therefore lights to determine the fragment colour? I know that doesnt make since sense because lighting should be done in the second render pass. In terms of normal mapping, do you essentially just pass the tangent,bitangents, and normals into g-buffers and then construct the tangent matrix and apply it to the sampled normal from the normal map. Ultimately, I would like to know how to incorporate this material information into my deferred renderer.

• Interacting with scene from controller/app delegate cocos2d

  - by cjroebuck

  I'm attempting to make my first cocos2d (for iphone) multiplayer game and having difficulty understanding how to interact with a scene once it is running. The game is a simple turn-based one and so I have a GameController class which co-ordinates the rounds. I also have a GameScene class which is the actual scene that is displayed during a round of the game. The basic interaction I need is for the GameController to be able to pass messages to the GameScene class.. such as StartRound/StopRound etc. The thing that complicates this is that I am loading the GameScene with a LoadingScene class which simply initialises the scene and replaces the current scene with this one, so there is no reference from GameController to GameScene, so passing messages is quite tricky. Does anyone have any ways to get around this, ideally I would still like to use a Loading class as it smooths out the memory hit when replacing scenes.

• how can i move static box2d object.

  - by user5198

  how can i move static box2d sprites. i have tried this tutorial from . http://www.raywenderlich.com/475/how-to-create-a-simple-breakout-game-with-box2d-and-cocos2d-tutorial-part-12. I managed to add another "paddle" object with box2d body, but i can seam to be able to make the code to move the second "paddle" body. Can anyone direct me how to do it? Is there a way to move a "b2_staticBody" box 2d object? i have tried, but i can only move it when i use "b2_dynamicBody" if i used "b2_staticBody" i can move it at all.

• How to monetize and/or protect framework rights?

  - by Arthur Wulf White

  I made a game engine/framerwork for ActionScript 3 that allows very efficient and flexible level design for Platformers, Tower Defense game, RPG's, RTS and racing games. The algorithms I used are new and are not available in any other level editor I've seen. What are the best ways to benefit myself and others with my new framework? It is written for ActionScript 3 so unless I translate it to C# I'm guessing it will be decompiled and used by others. I want to have some lisence, allowing me to share the framework and still benefit from it. Any advice would be appreciated. This issue has been on my mind a lot this year. I am hoping to find a solution that will bring me some relief.

• 2D Grid based game - how should I draw grid lines?

  - by Adam K Dean

  I'm playing around with a 2D grid based game idea, and I am using sprites for the grid cells. Let's say there is a 10 x 10 grid and each cell is 48x48, which will have sprites drawn there. That is fine. But in design mode, I'd like to have a grid overlay the screen. I can do this either with sprites (2x600 pixel image etc) or with primitives, but which is best? Should I really be switching between sprites and 3d/2d rendering? Like so: Thanks!

• Moving a body in a specific direction using XNA with Farseer Physics

  - by Code Assasssin

  I have a custom polygon attached to a body, which looks like this: What I am trying to accomplish is getting the body to move according to wherever the tip of the body is. So far this is what I've tried: if (ks.IsKeyDown(Keys.Up)) { body.ApplyForce(new Vector2(0, -20),body.GetLocalPoint(new Vector2(0,0))); } if (ks.IsKeyDown(Keys.Left)) { body.ApplyTorque(-500); } if (ks.IsKeyDown(Keys.Right)) { body.ApplyTorque(500); } The body rotates fine - but when I try making the body accelerate according to the tip of the body - assuming I have specified the tip correctly(I am pretty sure I haven't), it just spins around, as if I have applied Torque to it. Can anyone point me in the right direction of how to fix this problem?

• How to update entity states and animations in a component-based game

  - by mivic

  I'm trying to design a component-based entity system for learning purposes (and later use on some games) and I'm having some troubles when it comes to updating entity states. I don't want to have an update() method inside the Component to prevent dependencies between Components. What I currently have in mind is that components hold data and systems update components. So, if I have a simple 2D game with some entities (e.g. player, enemy1, enemy 2) that have Transform, Movement, State, Animation and Rendering components I think I should have: A MovementSystem that moves all the Movement components and updates the State components And a RenderSystem that updates the Animation components (the animation component should have one animation (i.e. a set of frames/textures) for each state and updating it means selecting the animation corresponding to the current state (e.g. jumping, moving_left, etc), and updating the frame index). Then, the RenderSystem updates the Render components with the texture corresponding to the current frame of each entity's Animation and renders everything on screen. I've seen some implementations like Artemis framework, but I don't know how to solve this situation: Let's say that my game has the following entities. Each entity have a set of states and one animation for each state: player: "idle", "moving_right", "jumping" enemy1: "moving_up", "moving_down" enemy2: "moving_left", "moving_right" What are the most accepted approaches in order to update the current state of each entity? The only thing that I can think of is having separate systems for each group of entities and separate State and Animation components so I would have PlayerState, PlayerAnimation, Enemy1State, Enemy1Animation... PlayerMovementSystem, PlayerRenderingSystem... but I think this is a bad solution and breaks the purpose of having a component-based system. As you can see, I'm quite lost here, so I'd very much appreciate any help.

• Detecting collision between ball (circle) and brick(rectangle)?

  - by James Harrison

  Ok so this is for a small uni project. My lecturer provided me with a framework for a simple brickbreaker game. I am currently trying to overcome to problem of detecting a collision between the two game objects. One object is always the ball and the other objects can either be the bricks or the bat. public Collision hitBy( GameObject obj ) { //obj is the bat or the bricks //the current object is the ball // if ball hits top of object if(topX + width >= obj.topX && topX <= obj.topX + obj.width && topY + height >= obj.topY - 2 && topY + height <= obj.topY){ return Collision.HITY; } //if ball hits left hand side else if(topY + height >= obj.topY && topY <= obj.topY + obj.height && topX + width >= obj.topX -2 && topX + width <= obj.topX){ return Collision.HITX; } else return Collision.NO_HIT; } So far I have a method that is used to detect this collision. The the current obj is a ball and the obj passed into the method is the the bricks. At the moment I have only added statement to check for left and top collisions but do not want to continue as I have a few problems. The ball reacts perfectly if it hits the top of the bricks or bat but when it hits the ball often does not change directing. It seems that it is happening toward the top of the left hand edge but I cannot figure out why. I would like to know if there is another way of approaching this or if people know where I'm going wrong. Lastly the collision.HITX calls another method later on the changes the x direction likewise with y.

• My frustum culling is culling from the wrong point

• XNA Transparency depending on drawing order?

  - by DarthRoman

  I am drawing two 3D objects, both of them can fade from opaque to transparent independently, and they can intersect between them (so you cannot say when one of them is before the other one). Look at the image for a better understanding (one of the object is a terrain and the other one an area): Now, if I apply transparency to both of them, and draw the terrain before the area, the terrain is not transparent respecting to the area, but the area is: And finally, if I draw the area before the terrain, then the area is not transparent respecting of the terrain: QUESTION: How can I make all the objects transparent to the rest of objects without depending on the drawing order?

• SFML - Moving a sprite on mouseclick

  - by Mike

  I want to be able to move a sprite from a current location to another based upon where the user clicks in the window. This is the code that I have: #include <SFML/Graphics.hpp> int main() { // Create the main window sf::RenderWindow App(sf::VideoMode(800, 600), "SFML window"); // Load a sprite to display sf::Texture Image; if (!Image.LoadFromFile("cb.bmp")) return EXIT_FAILURE; sf::Sprite Sprite(Image); // Define the spead of the sprite float spriteSpeed = 200.f; // Start the game loop while (App.IsOpened()) { if (sf::Keyboard::IsKeyPressed(sf::Keyboard::Escape)) App.Close(); if (sf::Mouse::IsButtonPressed(sf::Mouse::Right)) { Sprite.SetPosition(sf::Mouse::GetPosition(App).x, sf::Mouse::GetPosition(App).y); } // Clear screen App.Clear(); // Draw the sprite App.Draw(Sprite); // Update the window App.Display(); } return EXIT_SUCCESS; } But instead of just setting the position I want to use Sprite.Move() and gradually move the sprite from one position to another. The question is how? Later I plan on adding a node system into each map so I can use Dijkstra's algorithm, but I'll still need this for moving between nodes.

• How to spawn a character at certain point and walk to a set point

  - by Robert H.

  I am making a game where I have a background image of a neighborhood. Each location has a different number of customers that are generated to walk on sidewalks. They all walk to a specific location (like a stand or cart that sells stuff), after they get to location I want them to interact with the cart. However, if another customer is already in a sale interaction then the others get in line in order of arrival. After the transaction the customers walk off screen. Any information on how I can do this and what game engine would be needed? Any one have any idea where I should go for this. I already have my game done up through Eclipse/Java without any game engine.

• Converting a GameObject method call from UnityScript to C#

  Here is the UnityScript implementation of the method i use to generate a randomly tiled background, the problem i'm having relates to how to translate the call to the newTile method in c#, so far i've had no luck fiddling... can anyone point me in the correct direction? Thanks #pragma strict import System.Collections.Generic; var mapSizeX : int; var mapSizeY : int; var xOffset : float; var yOffset : float; var tilePrefab : GameObject; var tilePrefab2 : GameObject; var tiles : List.<Transform> = new List.<Transform>(); function Start () { var i : int = 0; var xIndex : int = 0; var yIndex : int = 0; xOffset = 2.69; yOffset = -1.97; while(yIndex < mapSizeY){ xIndex = 0; while(xIndex < mapSizeX){ var z = Random.Range(0, 5); if (z > 2) { var newTile : GameObject = Instantiate (tilePrefab, Vector3(xIndex*0.64 - (xOffset * (mapSizeX/10)), yIndex*-0.64 - (yOffset * (mapSizeY/10)), 0), Quaternion.identity); tiles.Add(newTile.transform); newTile.transform.parent = transform; newTile.transform.name = "tile_"+i; i++; xIndex++; } if (z < 2) { var newTile2 : GameObject = Instantiate (tilePrefab2, Vector3(xIndex*0.64 - (xOffset * (mapSizeX/10)), yIndex*-0.64 - (yOffset * (mapSizeY/10)), 0), Quaternion.identity); tiles.Add(newTile2.transform); newTile2.transform.parent = transform; newTile2.transform.name = "Ztile_"+i; i++; xIndex++; } } yIndex++; } } C# Version [Fixed] using UnityEngine; using System.Collections; public class LevelGen : MonoBehaviour { public int mapSizeX; public int mapSizeY; public float xOffset; public float yOffset; public GameObject tilePrefab; public GameObject tilePrefab2; int i; public System.Collections.Generic.List<Transform> tiles = new System.Collections.Generic.List<Transform>(); // Use this for initialization void Start () { int i = 0; int xIndex = 0; int yIndex = 0; xOffset = 1.58f; yOffset = -1.156f; while (yIndex < mapSizeY) { xIndex = 0; while(xIndex < mapSizeX) { int z = Random.Range(0, 5); if (z > 5) { GameObject newTile = (GameObject)Instantiate(tilePrefab, new Vector3(xIndex*0.64f - (xOffset * (mapSizeX/10.0f)), yIndex*-0.64f - (yOffset * (mapSizeY/10.0f)), 0), Quaternion.identity); tiles.Add(newTile.transform); newTile.transform.parent = transform; newTile.transform.name = "tile_"+i; i++; xIndex++; } if (z < 5) { GameObject newTile2 = (GameObject)Instantiate(tilePrefab, new Vector3(xIndex*0.64f - (xOffset * (mapSizeX/10.0f)), yIndex*-0.64f - (yOffset * (mapSizeY/10.0f)), 0), Quaternion.identity); tiles.Add(newTile2.transform); newTile2.transform.parent = transform; newTile2.transform.name = "tile2_"+i; i++; xIndex++; } } yIndex++; } } // Update is called once per frame void Update () { } }

• Unexpected results for projection on to plane

  - by ravenspoint

  I want to use this projection matrix: GLfloat shadow[] = { -1,0,0,0, 1,0,-1,1, 0,0,-1,0, 0,0,0,-1 }; It should cast object shadows onto the y = 0 plane from a point light at 1,1,-1. I create a rectangle in the x = 0.5 plane glBegin( GL_QUADS ); glVertex3f( 0.5,0.2,-0.5); glVertex3f( 0.5,0.2,-1.5); glVertex3f( 0.5,0.5,-1.5); glVertex3f( 0.5,0.5,-0.5); glEnd(); Now if I manually multiply these vertices with the matrix, I get. glBegin( GL_QUADS ); glVertex3f( 0.375,0,-0.375); glVertex3f( 0.375,0,-1.625); glVertex3f( 0,0,-2); glVertex3f( 0,0,0); glEnd(); Which produces a reasonable display ( camera at 0,5,0 looking down y axis ) So rather than do the calculation manually, I should be able to use the opengl model transormation. I write this code: glMatrixMode (GL_MODELVIEW); GLfloat shadow[] = { -1,0,0,0, 1,0,-1,1, 0,0,-1,0, 0,0,0,-1 }; glLoadMatrixf( shadow ); glBegin( GL_QUADS ); glVertex3f( 0.5,0.2,-0.5); glVertex3f( 0.5,0.2,-1.5); glVertex3f( 0.5,0.5,-1.5); glVertex3f( 0.5,0.5,-0.5); glEnd(); But this produces a blank screen! What am I doing wrong? Is there some debug mode where I can print out the transformed vertices, so I can see where they are ending up? Note: People have suggested that using glMultMatrixf() might make a difference. It doesn't. Replacing glLoadMatrixf( shadow ); with glLoadIdentity(); glMultMatrixf( shadow ); gives the identical result ( of course! )

• How do I implement movement in a WPF Adventure game?

  - by ZeroPhase

  I'm working on making a short WPF adventure game. The only major hurdle I have right now is how to animate objects on the screen correctly. I've experimented with DoubleAnimation and ThicknessAnimation both enable movement of the character, but the speed is a bit erratic. The objects I'm trying to move around are labels in a grid, I'm checking the mouse's position in terms of the canvas I have the grid in. Does anyone have any suggestions for coding the movement, while still allowing mouse clicks to pick up items when needed? It would be nice if I could continue using the Visual Studio GUI Editor. By the way, I'm fine with scrapping labels in a grid for a more ideal object to manipulate. Here's my movement code: ThicknessAnimation ta = new ThicknessAnimation(); The event handling movement: private void Hansel_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { ta.FillBehavior = FillBehavior.HoldEnd; ta.From = Hansel.Margin; double newX = Mouse.GetPosition(PlayArea).X; double newY = Mouse.GetPosition(PlayArea).Y; if (newX < Convert.ToDouble(Hansel.Margin.Left)) { //newX = -1 * newX; ta.To = new Thickness(0, newY, newX, 0); } else if (newY < Convert.ToDouble(Hansel.Margin.Top)) { newY = -1 * newY; } else { ta.To = new Thickness(newX, newY, 0, 0); } ta.Duration = new Duration(TimeSpan.FromSeconds(2)); Hansel.BeginAnimation(Grid.MarginProperty, ta); } ScreenShot with annotations: http://i1118.photobucket.com/albums/k608/sealclubberr/clickToMove_zps9d4a33cc.png ScreenShot with example movement: http://i1118.photobucket.com/albums/k608/sealclubberr/clickToMove_zps51f2359f.jpg
