• XNA 4.0 - container with content, that can slide (C#)

  - by DijkeMark

  I got an idea, but I got no idea on how to make it. Okay, so here is the deal. I want a container which can contain certain objects (These objects will draw the sprites/graphics). But because of different screen sizes, I want to be able to scale the containers width and height. But I do not want the objects in the container, that go outside of the container, because of the scaling to be visible. Because I want the objects all to be positioned horizontaly to eachother and I want a horizontal sliderbar, so I can slide from left to right within the container. I wonder if anyone could point me in the right direction. Thanks in Advance, Mark

• Implementing a Risk-style board

  - by pouzzler

  I have two images of the same dimensions. One is represents the game board in a user-appealing way, the other represents it in a computer-friendly way where each game area is painted in a unique, uniform color. When the user clicks the board, we get the click coordinates, find the color of the pixel at the same coordinates in our second image, and that color is directly translatable to a game area, since each area is painted in its own color. Is that a good implementation? Can you suggest better, if it isn't? Best regards.

• How should I implement multiple threads in a game? [duplicate]

  - by xerwin

  This question already has an answer here: Multi-threaded games best practices. One thread for 'logic', one for rendering, or more? 6 answers So I recently started learning Java, and having a interest in playing games as well as developing them, naturally I want to create game in Java. I have experience with games in C# and C++ but all of them were single-threaded simple games. But now, I learned how easy it is to make threads in Java, I want to take things to the next level. I started thinking about how would I actually implement threading in a game. I read couple of articles that say the same thing "Usually you have thread for rendering, for updating game logic, for AI, ..." but I haven't (or didn't look hard enough) found example of implementation. My idea how to make implementation is something like this (example for AI) public class AIThread implements Runnable{ private List<AI> ai; private Player player; /*...*/ public void run() { for (int i = 0; i < ai.size(); i++){ ai.get(i).update(player); } Thread.sleep(/* sleep until the next game "tick" */); } } I think this could work. If I also had a rendering and updating thread list of AI in both those threads, since I need to draw the AI and I need to calculate the logic between player and AI(But that could be moved to AIThread, but as an example) . Coming from C++ I'm used to do thing elegantly and efficiently, and this seems like neither of those. So what would be the correct way to handle this? Should I just keep multiple copies of resources in each thread or should I have the resources on one spot, declared with synchronized keyword? I'm afraid that could cause deadlocks, but I'm not yet qualified enough to know when a code will produce deadlock.

• What is the proper way to use string::find to look for a word? [migrated]

  - by RubyKing

  How would I look through a string for a word rather then each character in that word. I have my code here and it always seems to find everything that is .obj even if its o or b or j or "." I checked the docuementation here but was unable to find an answer. Here is my code: string &str = *it; if(it->find(".obj")) { cout << "Found .Obj" << endl; } I also tried to use string::compare but that failed.

• Directional Lights

  - by Setrio

  I'm working on a game idea (2D) that needs directional lights. Basically I want to add light sources that can be moved and the light rays interact with the other bodies on the scene. What I'm doing right now is some test where using sensors (box2d) and ccDrawLine I could achieve something similar to what I want. Basically I send a bunch of sensors from certain point and with raycast detect collisions, get the end points and draw lines over the sensors. Just want to get some opinions if this is a good way of doing this or is other better options to build something like this? Also I would like to know how to make a light effect over this area (sensors area) to provide a better looking light effect. Any ideas?

• Artificial Neural Networks

  - by user1724140

  I have an Artificial Networks which needs to recognize 130 different types of moves encoded in terms of 1s and 0s. Therefore the number of outputs I used is 8 so that all my patterns could be distinguished. However, by using 8 outputs, the different types of patterns possible is 256, leaving me with 126 different types of patterns useless. Do these extra 126 different patterns ruin my ANN's ability? Is there a better way not to have these unused holes?

• Open source Entity-Component game [on hold]

  - by Papavoikos

  I've been reading a lot about entity-component design but every article talks about the philosophy behind such design, leaving a lot of details and implementations outside. I'm looking for an open source game that uses the entity-component design so I can study the concrete implementations and see how they deal with things such as How (and if) they deal with inter-component communication How much logic each component has or doesn't have How a subsystem can change it's behavior depending on an entity's state (the screen darkens depending on the player's health)

• Portable C++ IDE

  - by Click Ok

  I want a portable C++ IDE for general development, and too to develop basic Windows GUI applications. In my research, I've found this (with latest version date): CodeLite IDE (2010-04-02) Code::Blocks (2008-02-28) Bloodshed Dev-C++ (2005-02-22) NetBeans (2009-12-10) Ultimate++ (2010-03-16) Qt Creator (2010-02-01) But I don't know if some these IDE's supports Windows GUI development (or Cross Platform GUI development) or if can be Portable (NetBeans can be portable).

• Separate parts of a game engine [on hold]

  - by user272716

  I'm pretty new in developing videogames. By now I only used SDL with C/C++ to create games. I'm currently learning OpenGL and I realized that to be fluid and easy to maintain the code must be logically separated. Since I want to use OpenGLES on iOS and Android I was wondering how the engine must be imagined in a technical way, some questions came up: Do I have to separate input/update functions from draw functions in different threads? Is there only one proper way to think a game engine/loop? What kind of assets should I use to create a 3D game using openGl ES to get better performance?

• How can I add a character and enemies to a game that uses Parallax Scrolling? [on hold]

  - by Homer_Simpson

  I use the following code to create Parallax Scrolling: http://www.david-gouveia.com/portfolio/2d-camera-with-parallax-scrolling-in-xna/ Parallax Scrolling is working but I don't know how to add the player and the enemies. I tried to add a player class to the existing code, but if the player moves, then the camera isn't pointing at the player. The player leaves the camera viewport after a few seconds. I use the following code(as described in the tutorial), but it's not working: // Updates my camera to lock on the character _camera.LookAt(player.Playerposition); What can I do so that the player is always the center of the camera? How should I add the character and the enemies to the game? Should I create a layer for the character and the enemies? For example: new Layer(_camera) { Parallax = new Vector2(0.9f, 1.0f) } At the moment, I don't use a layer for the player and I don't have implemented the enemies because I don't know how to do that. My player class: public class Player { Texture2D Playertex; public Vector2 Playerposition = new Vector2(400, 240); private Game1 game1; public Player(Game1 game) { game1 = game; } public void Load(ContentManager content) { Playertex = content.Load<Texture2D>("8bitmario"); TouchPanel.EnabledGestures = GestureType.HorizontalDrag; } public void Update(GameTime gameTime) { while (TouchPanel.IsGestureAvailable) { GestureSample gs = TouchPanel.ReadGesture(); switch (gs.GestureType) { case GestureType.HorizontalDrag: Playerposition.X += 3f; break; } } } public void Render(SpriteBatch batch) { batch.Draw(Playertex, new Vector2(Playerposition.X - Playertex.Width / 2, Playerposition.Y - Playertex.Height / 2), Color.White); } } In Game1, I update the player and camera class: protected override void Update(GameTime gameTime) { // Updates my character's position player.Update(gameTime); // Updates my camera to lock on the character _camera.LookAt(player.Playerposition); base.Update(gameTime); } protected override void Draw(GameTime gameTime) { GraphicsDevice.Clear(Color.CornflowerBlue); foreach (Layer layer in _layers) layer.Draw(spriteBatch); spriteBatch.Begin(SpriteSortMode.Deferred, null, null, null, null, null, _camera.GetViewMatrix(new Vector2(0.0f, 0.0f))); player.Render(spriteBatch); spriteBatch.End(); base.Draw(gameTime); }

• libgdx - #iterator() cannot be used nested

  - by TimSim

  I'm getting this error when I try to check if any of the targets overlap each other: iterTargets = targets.iterator(); while (iterTargets.hasNext()) { Target target = iterTargets.next(); for (Target otherTarget:targets) { if (target.rectangle.overlaps(otherTarget.rectangle)) { // do something } } } So I can't do that? How am I supposed to check each member of an array to see if it overlaps any other member?

• Function for building an isosurface (a sphere cut by planes)

  - by GameDevEnthusiast

  I want to build an octree over a quarter of a sphere (for debugging and testing). The octree generator relies on the AIsosurface interface to compute the density and normal at any given point in space. For example, for a full sphere the corresponding code is: // returns <0 if the point is inside the solid virtual float GetDensity( float _x, float _y, float _z ) const override { Float3 P = Float3_Set( _x, _y, _z ); Float3 v = Float3_Subtract( P, m_origin ); float l = Float3_LengthSquared( v ); float d = Float_Sqrt(l) - m_radius; return d; } // estimates the gradient at the given point virtual Float3 GetNormal( float _x, float _y, float _z ) const override { Float3 P = Float3_Set( _x, _y, _z ); float d = this->AIsosurface::GetDensity( P ); float Nx = this->GetDensity( _x + 0.001f, _y, _z ) - d; float Ny = this->GetDensity( _x, _y + 0.001f, _z ) - d; float Nz = this->GetDensity( _x, _y, _z + 0.001f ) - d; Float3 N = Float3_Normalized( Float3_Set( Nx, Ny, Nz ) ); return N; } What is a nice and fast way to compute those values when the shape is bounded by a low number of half-spaces?

• What is w componet [duplicate]

  - by Tifa

  This question already has an answer here: What does the graphics card do with the fourth element of a vector as the final position? 3 answers What is the W component on graphics programming. I read a blog about opengl that says that w must be equal to either 0 or 1 here. But the book I am currently reading has put w component to more than 1 value. So im kinda confuse what does it really do. The book I am reading is OpenGL es a quick start guide.

• If and else condition not working properly in xna [closed]

  - by user1090751

  I am developing chess like game and i wanted to show error message if user try to place any player inside the box which is not empty. For example in certain place if there is empty then the object(2d object) is placed else it should show error message. However in my program it is showing message everytime i.e when i place object on empty place then also it is showing error message. Please see the below code: protected override void Update(GameTime gameTime) { // Allows the game to exit if (GamePad.GetState(PlayerIndex.One).Buttons.Back == ButtonState.Pressed) this.Exit(); // TODO: Add your update logic here for (int i = 0; i < 25; i++) { MouseState mouseState; mouseDiBack = false; mouseState = Mouse.GetState(); if (new Rectangle(mouseState.X, mouseState.Y, 1, 1).Intersects(rect_arr[i])) { background_color_arr[i] = Color.Red; } else { background_color_arr[i] = Color.White; } if (new Rectangle(mouseState.X, mouseState.Y, 1, 1).Intersects(rect_arr[i]) && (mouseState.LeftButton == ButtonState.Pressed)) { if (boxes[i] != "goat" && boxes[i] != "tiger") { place = i; if (turn == "goat") { boxes[i] = "goat"; turn = "tiger"; } else { boxes[i] = "tiger"; turn = "goat"; } } else { errMsg = "This " + i + " block is not empty to place " + turn + ". Please select empty block!!"; } } } base.Update(gameTime); }

• How to check if a variable is an integer? [closed]

  - by FyrePlanet

  I'm going through my C++ book and have currently made a working Guess The Number game. The game generates a random number based on current time, has the user input their guess, and then tells them whether it was too high, too low, or the correct number. The game functions fine if you enter a number, but returns 'Too High' if you enter something that is not a number (such as a letter or punctuation). Not only does it return 'too high', but it also continually returns it. I was wondering what I could do to check if the guess, as input by the user, is an integer and if it is not, to return 'Not a number. Guess again.' Here is the code. #include <iostream> #include <cstdlib> #include <ctime> using namespace std; int main() { srand(time(0)); // seed the random number generator int theNumber = rand() % 100 + 1; // random number between 1 and 100 int tries = 0, guess; cout << "\tWelcome to Guess My Number!\n\n"; do { cout << "Enter a guess: "; cin >> guess; ++tries; if (guess > theNumber) cout << "Too high!\n\n"; if (guess < theNumber) cout << "Too low!\n\n"; } while (guess != theNumber); cout << "\nThat's it! You got it in " << tries << " guesses!\n"; cout << "\nPress Enter to exit.\n"; cin.ignore(cin.rdbuf()->in_avail() + 1); return 0; }

• How do I have an arrow follow different height parabolas depending on how long the player holds down a key?

  - by Moondustt

  i'm trying to throw an arrow in my game, but i'm having a hard time trying to realize how to make a good parabola. What I need: The more you hold "enter" stronger the arrow goes. The arrow angle will be always the same, 45 degrees. This is what I have already have: private float velocityHeld = 1f; protected override void Update(GameTime gameTime) { private void GetKeyboardEvent() { if (Keyboard.GetState().IsKeyDown(Keys.Enter) && !released) { timeHeld += velocityHeld; holding = true; } else { if (holding) { released = true; holding = false; lastTimeHeld = timeHeld; } } } if (released && timeHeld > 0) { float alpha = MathHelper.ToRadians(45f); double vy = timeHeld * Math.Sin(alpha); double vx = timeHeld * Math.Cos(alpha); ShadowPosition.Y -= (int)vy; ShadowPosition.X += (int)vx; timeHeld -= velocityHeld; } else { released = false; } } My question is, what do I need to do to make the arrow to go bottom as it loses velocity (timeHeld) to make a perfect parabola?

• Game Database Connectivity Java

  - by The Kraken

  I'm developing a simple multi-player puzzle game in Java. Both players should be able to view the same game board on his own computer. Then, when one player makes an action in the game (ex. drags an object onto a coordinate space), the game's view should update automatically on the other computer's game screen. I'd like all this to happen over the internet, not requiring both computers to be on the same LAN connection. If I need to use SQL/PHP to accomplish this, I'm unsure how to design the database to accomplish something as simple as the following: Player A drags element onscreen Game sends coordinates of element to database/server Player B's computer detects a change to an item in the database Player B's computer grabs the coordinates of Player A's item Player B's machine draws onscreen elements at the received coordinates Could somebody point me in the right direction?

• How to avoid tons of `instanceof` in collision detection?

  - by Prog

  Consider a simple game with 4 kinds of entities: Robots, Dogs, Missiles, Walls. Here's a simple collision-detection mechanism in psuedocode: (I know, O(n^2). Irrelevant for this question). for(Entity entityA in entities){ for(Entity entityB in entities){ if(collision(entityA, entityB)){ if(entityA instanceof Robot && entityB instanceof Dog) entityB.die(); if(entityA instanceof Robot && entityB instanceof Missile){ entityA.die(); entityB.die(); } if(entityA instanceof Missile && entityB instanceof Wall) entityB.die(); // .. and so on } } } Obviously this is very ugly, and will get bigger and harder to maintain the more entities there are, and the more conditions there are. One option to make this better is to have separate lists for each kind of entity. For example a Robots list, a Dogs list etc. And than check for collisions of all Robots with Dogs, and all Dogs with Walls, etc. This is better, but I still don't think it's good. So my question is: The collision detection system spotted a collision. Now what? What is the common way to react to the collision? Should the system notify the entity itself that it collided with something, and have it decide for itself how to react? E.g. entityA.reactToCollision(entityB). Or is there some other solution?

• Organize a game set

  - by jncunha

  I'm developing a endless running game and I'm not really sure on how to make the set. The first approach was to make a BIG set like 10240x3072 pixels so that we have a nice portion of set. After having like 3 or 4 sets that go along with each other I would work on making their elements sequential and repeatable. However this is getting really heavy for the iPad 1 (it's running good in the iPad 2 and the New iPad) even though I'm splitting all the set in slices through Photoshop. For the implementation I'm using Cocos2D. Is there any better approach to make something like this but truly efficient for the iPad memory? Thank you.

• TexturePacker ignores extensions

  - by The Oddler

  I'm using TexturePacker in one of my games, though when packing a bunch of textures their extension is kept in the data file. So when I want to find a texture I need to search for "image.png" instead of just "image". Is there an option to let texture packer ignore the extensions of my source images in the data file? Solved: So if anyone else wants this, here's the exported I made: https://www.box.com/s/bf12q1i1yc9jr2c5yehd Just extract it into "C:\Program Files (x86)\CodeAndWeb\TexturePacker\bin\exporters\UIToolkit No Extensions" (or something similar) and it should show op as an exporter.

• How to visualize real time data on Android? [closed]

  I want to build and android app that visualizes real time data (2D animation). I set up a UDP channel that get the data, now I want to visualize it. I know that I can use OpenGL ES, but after a few weeks, I dont think that I'm able to learn that. What about Android Processing? Could it be used for an extensive visualization task like this? or is it limited in some way? I've heard it's not hard learn. Any other options?

• Concept: Interpretive Spells [closed]

  - by Deathly

  The goal is to be able to create complex spells, that can manipulate the game's environment in non-preprogrammed ways, and to make the program understand spells. For example: $@ $=Big @=Fire You can probably understand what this one means. The player types, writes, or selects symbols. Of course, a spell can be only a few characters, or more sophisticated spells could potentially be hundreds or thousands of symbols long. How could something like this be accomplished?

• Is It More Efficient To Make Games In Languages I Like?

  - by Dsfsdfsdfsdfsd Fsdf

  Is it more "efficiant" to develop games with languages your good with and like best rather then the "best" language? A example is like I like C# (It's My First Language) and I'm really good at it and used to how it works, I'm not as good with C++ but I'm kinda slow at it because I don't prefer how you systems work like I think int a[] is not as good as int[] a. Would it be better to go with what I know best or what's the "best" available? Thanks For Reading!
