• 2d Ice movement

  - by Jeremy Clarkson

  I am building an top-down 2d RPG like zelda. I have been trying to implement ice sliding. I have a tile with the slide property. I thought it would be easy to get working. I figured that I would read the slide property, and move the character forward until the slide property no longer exists. So I tried a loop but all it did was stop at the first tile in an infinite loop. I then took the loop out and tried taking direct control of the character to move him along the slide path but I couldn't get it to move. Is there an easy way to do an ice sliding tile based movement in libgdx. I looked for a tutorial but none exist.

• Octree subdivision problem

  - by ChaosDev

  Im creating octree manually and want function for effectively divide all nodes and their subnodes - For example - I press button and subnodes divided - press again - all subnodes divided again. Must be like - 1 - 8 - 64. The problem is - i dont understand how organize recursive loops for that. OctreeNode in my unoptimized implementation contain pointers to subnodes(childs),parent,extra vector(contains dublicates of child),generation info and lots of information for drawing. class gOctreeNode { //necessary fields gOctreeNode* FrontBottomLeftNode; gOctreeNode* FrontBottomRightNode; gOctreeNode* FrontTopLeftNode; gOctreeNode* FrontTopRightNode; gOctreeNode* BackBottomLeftNode; gOctreeNode* BackBottomRightNode; gOctreeNode* BackTopLeftNode; gOctreeNode* BackTopRightNode; gOctreeNode* mParentNode; std::vector<gOctreeNode*> m_ChildsVector; UINT mGeneration; bool mSplitted; bool isSplitted(){return m_Splitted;} .... //unnecessary fields }; DivideNode of Octree class fill these fields, set mSplitted to true, and prepare for correctly drawing. Octree contains basic nodes(m_nodes). Basic node can be divided, but now I want recursivly divide already divided basic node with 8 subnodes. So I write this function. void DivideAllChildCells(int ix,int ih,int id) { std::vector<gOctreeNode*> nlist; std::vector<gOctreeNode*> dlist; int index = (ix * m_Height * m_Depth) + (ih * m_Depth) + (id * 1);//get index of specified node gOctreeNode* baseNode = m_nodes[index].get(); nlist.push_back(baseNode->FrontTopLeftNode); nlist.push_back(baseNode->FrontTopRightNode); nlist.push_back(baseNode->FrontBottomLeftNode); nlist.push_back(baseNode->FrontBottomRightNode); nlist.push_back(baseNode->BackBottomLeftNode); nlist.push_back(baseNode->BackBottomRightNode); nlist.push_back(baseNode->BackTopLeftNode); nlist.push_back(baseNode->BackTopRightNode); bool cont = true; UINT d = 0;//additional recursive loop param (?) UINT g = 0;//additional recursive loop param (?) LoopNodes(d,g,nlist,dlist); //Divide resulting nodes for(UINT i = 0; i < dlist.size(); i++) { DivideNode(dlist[i]); } } And now, back to the main question,I present LoopNodes, which must do all work for giving dlist nodes for splitting. void LoopNodes(UINT& od,UINT& og,std::vector<gOctreeNode*>& nlist,std::vector<gOctreeNode*>& dnodes) { //od++;//recursion depth bool f = false; //pass through childs for(UINT i = 0; i < 8; i++) { if(nlist[i]->isSplitted())//if node splitted and have childs { //pass forward through tree for(UINT j = 0; j < 8; j++) { nlist[j] = nlist[j]->m_ChildsVector[j];//set pointers to these childs } LoopNodes(od,og,nlist,dnodes); } else //if no childs { //add to split vector dnodes.push_back(nlist[i]); } } } This version of loop nodes works correctly for 2(or 1?) generations after - this will not divide neightbours nodes, only some corners. I need correct algorithm. Screenshot All I need - is correct version of LoopNodes, which can add all nodes for DivideNode.

• Do I need to create my own or use a commercial server for the features and matchmaking options I want my game to support?

  - by baptzmoffire

  So I'm developing an indie turn-based game for iOS and, in coding up a Game Center matchmaking class, I'm starting to question whether Game Center is even the best choice for what I want this game to do. I need to figure out whether I need to create my own server, invest in a preexisting client or server service, or if I even need to use a server at all. If I do need to use a ready-made service other than Game Center, which server would accomodate my game's needs best? I have limited resources and funds. Here is the list of features I want my game to support, ideally: Turn-based gameplay (a la "with Friends" and "with Buddies" games) Smart matchmaking (matching users up with other players of comparable skill/achievements) Random matchmaking Facebook matchmaking Specific username matchmaking Contact list matchmaking A way to select what "type" of match you want to challenge an opponent to. (In random, smart, and Facebook matchmaking, there will be different "wagers" the player can make. [e.g. "I wanna play a random opponent for 1000 points. Now, I wanna play my Facebook buddy for 1,000,000 points."] There will be a predetermined range of amounts you can play for. It won't be customizable.) Buddies list capability (Game-buddies, as opposed to contacts and Facebook) A higher concurrent game cap than Game Center offers (which I still can't really find a straight answer on) Scalability (it should support 2 or 20,000,000 players) Objective-C compatibility Flexibility (for all the stuff I haven't thought of yet) Am I dreaming, here? Is there even a service that can handle all of these features? Do I need to invest months in learning a networking language to build my own? If so, how much would I need to spend on hardware? I've been looking around all morning and, so far, the only seemingly viable option is SmartFox. Under "Everything and the kitchen sink" section here, it says they support "virtual world with Zones, Rooms and RoomGroups, create complex game challenges, send invitations, manage buddy lists, create custom permission profiles, oversee the security aspects and tons more." http://www.smartfoxserver.com/overview/platform Is there an option that Im just overlooking? Thanks for any help anyone can provide. Sorry for the long poast. One last question: Does anyone know which server Dice with Buddies uses? I was experimenting with how many concurrent games I could get going and my ADHD kicked in at about 80 games. 80 concurrent games would be great for my game, but again, I need the other features I mentioned too. Thanks again.

• dynamic 2d texture creation in unity from script

  - by gman

  I'm coming from HTML5 and I'm used to having the 2D Canvas API I can use to generate textures. Is there anything similar in Unity3D? For example, let's say at runtime I want to render a circle, put 3 initials in the middle and then take the result and put that in a texture. In HTML5 I'd do this var initials = "GAT"; var textureWidth = 256; var textureHeight = 256; // create a canvas var c = document.createElement("canvas"); c.width = textureWidth; c.height = textureHeight; var ctx = c.getContext("2d"); // Set the origin to the center of the canvas ctx.translate(textureWidth / 2, textureHeight / 2); // Draw a yellow circle ctx.fillStyle = "rgb(255,255,0)"; // yellow ctx.beginPath(); var radius = (Math.min(textureWidth, textureHeight) - 2) / 2; ctx.arc(0, 0, radius, 0, Math.PI * 2, true); ctx.fill(); // Draw some black initials in the middle. ctx.fillStyle = "rgb(0,0,0)"; ctx.font = "60pt Arial"; ctx.textAlign = "center"; ctx.fillText(initials, 0, 30); // now I can make a texture from that var tex = gl.createTexture(); gl.bindTexture(gl.TEXTURE_2D, tex); gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, gl.RGBA, gl.UNSIGNED_BYTE, c); gl.generateMipmap(gl.TEXTURE_2D); I know I can edit individual pixels in a Unity texture but is there any higher level API for drawing to texture in unity?

• Correct order of tasks in each frame for a Physics simulation

  - by Johny

  I'm playing a bit around with 2D physics. I created now some physic blocks which should collide with each other. This works fine "mostly" but sometimes one of the blocks does not react to a collision and i think that's because of my order of tasks done in each frame. At the moment it looks something like this: function GameFrame(){ foreach physicObject do AddVelocityToPosition(); DoCollisionStuff(); // Only for this object not to forget! AddGravitationToVelocity(); end RedrawScene(); } Is this the correct order of tasks in each frame?

• Loading and drawing materials using Lib3ds

  - by Dfowj

  Hey all, i'm currently using Lib3ds to load models into my C++/OpenGL project. So far, i've been follow the model loading tutorial found here. The tutorial gives a good example of how to draw the vertices and normals using VBO's, but so far i've been lost as how to do the same thing with materials. Could i get an explanation/example of how to both load and draw materials of my meshes using Lib3ds and OpenGL?

• Pixel perfect collision with paths (Android)

  - by keysersoze

  Hi I'm writing a game and I'm trying to do some pixel perfect collisions with paths. The player's character has a bitmask which looks for example like this: Currenly my code that handles player's collision with path looks like this: private boolean isTerrainCollisionDetected() { if(collisionRegion.op(player.getBounds(), terrain.getBottomPathBounds(), Region.Op.INTERSECT) || collisionRegion.op(player.getBounds(), terrain.getTopPathBounds(), Region.Op.INTERSECT)) { collisionRegion.getBounds(collisionRect); for(int i = collisionRect.left; i < collisionRect.right; i++) { for(int j = collisionRect.top; j < collisionRect.bottom; j++) { if(player.getBitmask().getPixel(i - player.getX(), j - player.getY()) != Color.TRANSPARENT) { return true; } } } } return false; } The problem is that collisions aren't pixel perfect. It detects collisions in situations like this: The question is: what can I do to improve my collision detection?

• Simple collision detection in Unity 2D

  - by N1ghtshade3

  I realise other posts exist with this topic yet none have gone into enough detail for me. I am attempting to create a 2D game in Unity using C# as my scripting language. Basically I have two objects, player and bomb. Both were created simply by dragging the respective PNG to the stage. I have set up touch controls to move player left and right; gravity of any kind is not needed as I only require it to move x units when I tap either the left or right side of the screen. This movement is stored in a script called playerController.cs and works just fine. I also have a variable health = 3 for player, which is stored in healthScript.cs. I am now at a point where I am stuck. I would like it so that when player collides with bomb, health decreases by one and the bomb object is destroyed. So what I tried doing is using a new script called playerPhysics.cs, I added the following: void OnCollisionEnter2D(Collision2D coll){ if(coll.gameObject.name=="bomb") GameObject.Destroy("bomb"); healthScript.health -= 1; } While I'm fairly sure I don't know the proper way to reference a variable in another script and that's why the health didn't decrease when I collided, bomb never disappeared from the stage so I'm thinking there's also a problem with my collision. Initially, I had simply attached playerPhysics.cs to player. After searching around though, it appeared as though player also needed a rigidBody attached to it, so I did that. Still no luck. I tried using a circleCollider (player is a circle), using a rigidBody2D, and using all manner of colliders on one and/or both of the objects. If you could please explain what colliders (if any) should be attached to which objects and whether I need to change my script(s), that would be much more helpful than pointing me to one of the generic documentation examples I've already read. Also, if it would be simple to fix the health thing not working that would be an added bonus but not exactly the focus of this question. Bear in mind that this game is 2D; I'm not sure if that changes anything. Thanks!

• Worker roles in Windows Azure to host a multiplayer server

  - by MrWiggels

  I've been doing research on where to host a simple multi-player backend for a simple game I'm developing. So as a first choice I downloaded the Windows Azure SDK, which provides a nice and simple emulator environment where you can test out your application before uploading. I also download the Azure Social Game Toolkit (Visit), and followed as far as my understanding can take me. So, down to the main question. Is there anybody with experience developing Azure applications. I'm developing a Action RPG game, in a similar vein to Diablo III. I was thinking of putting up Matchmaking, Friends Lists, etc. Is there another way to connect to Azure services via something like UDP or TCP for sending packets or does everything have to go through HTTP requests? Is it even possible to use HTTP request/response for something like this? All game commands will be simple. Because the game server and the clients will be kept in-sync and will have deterministic actions, I'm just going to send actions like "Use Primary Skill" and "Use Secondary Skill". Any hints, ideas, light bulbs or a smack-in-the-face presentation will be much appreciated.

• Beggining OpenGL vs beggining DirectX and some question about the philosophical difference between them

  - by jokoon

  I'm begginning with Direct X at school, and my teacher said it was harder to begin with than OpenGL, but I read several things that in fact, Direct X was more advanced than OpenGL in terms of recent graphic cards features. Since I'm far from wanting to do top notch effects, which can already be implemented with existing engines and/or shaders, I wanted to know your opinion: Can OpenGL be considered like a more basic, KISS, hardware agnostic, graphic library to just do 3D with acceleration, and consider DirectX like a top notch, game-oriented graphic API that will always support the next-gen 3D chips ? Citation from wikipedia on http://en.wikipedia.org/wiki/Id_Tech_5 : John Carmack mentioned in his keynote at QuakeCon 2007 that the id Tech 5 engine will not be using the DirectX 10 API. I don't want to seem like I'm minding open source because Carmack does and because he is famous, it's just that android and iPhone are out there, and Direct X doesn't seems to me to be the necessary API to know, since Windows supports OpenGL, and since the 360 is just a console among other consoles.

• Is it normal to these Xcode prompts/errors when you deploy to IOS Simulator from Unity?

  - by Greg

  Just trying out the IOS build process.... Is it normal to see: Q1 - "upgrade to latest project format - project currently in Xcode 3.1 format, this will upgrade to 3.2" - just click OK and let Xcode do it's stuff? Q2 - same as Q1 but this time for the message "Remove obsolete build settings - will remove the build setting PREBINDING" Q3 - also when deploying to "Lastest IOS Simulator" you get the Simulator target produced, but also a non-simulator target which has lots of errors. So I assume you just ignore this target and not use it in Xcode correct? (i.e. just use the simulator target that is produced) Q4 - get a lot of warning after the simulator target is built? program works ok however.... Images For Q1 and Q2: For Q4: Settings used in Unity: Errors I see in XCode:

• ScreenManagement how do I had different controls?

  - by DiasFrancisco

  I saw a question here using DataTemplates with WPF for ScreenManagement, I was curious and I gave it a try I think the ideia is amazing and very clean. Though I'm new to WPF and I read a lot of times that almost everything should be made in XAML and very little should be "coded behind". My questions resolves about using the datatemplate ideia, WHERE should the code that calls the transitions be? where should I define which commands are avaiable in which screens. For example: [ScreenA] Commands: Pressing B - Goes to state B Pressing ESC - Exits [ScreenB] Commands: Pressing A - Goes to state A Pressing SPACE - Exits where do I define the keyEventHandlers? and where do I call the next screen? I'm doing this as an hobby for learning and "if you are learning, better learn it right" :) Thank you for your time.

• Level and Player objects - which should contain which?

  - by Thane Brimhall

  I've been working on a several simple games, and I've always come to a decision point where I have to choose whether to have the Level object as an attribute of the Player class or the Player as an attribute of the Level class. I can see arguments for both: The Level should contain the player because it also contains every other entity. In fact it just makes sense this way: "John is in the room." It makes it a bit more difficult to move the player to a new level, however, because then each level has to pass its player object to an upcoming level. On the other hand, it makes programming sense to me to leave the player as the top-level object that is persistent between levels, and the environment changes because the player decides to change his level and location. It becomes very easy to change levels, because all I have to do is replace the level variable on the player. What's the most common practice here? Or better yet, is there a "right" way to architecture this relationship?

• Confusion with Libgdx UI

  - by BrotherJack

  I've started with Libgdx and am currently stumbling about trying to understand how to set up the interface. I have generated the base projects in Eclipse ( < proj-name ,< proj-name -android, < proj-name -desktop, < proj-name -html), and can get the program to display a simple background, play a looping sound file, and draw a tank. I have been having some problems implementing the UI though. I want to make a collapsible interface bar at the bottom of the screen that would contain buttons for movement, and selecting weapons. I'm confused since there appears to be several ways of doing this and the documentation (or tutorials explaining it) tend to be obsolete. How would one go about this? Use a stage for the bar and actors for the widgets? I'm a little lost on this.

• Resources on expected behaviour when manipulating 3D objects with the mouse

  - by sebf

  Hello, In my animation editor, I have a 3D gizmo that sits on the origin of a bone; the user drags the mesh around to rotate the bone. I've found that translating the 2D movements of the mouse into sensible 3D transforms is not near as simple as i'd hoped. For example what is intuitively 'up' or 'down'? How should the magnitude of rotations change with respect to dX/dY? How to implement this? What happens when the gizmo changes position or orientation with respect to the camera? ect. So far with trial and error i've written something (very) simple that works 70% of the time. I could probably continue to hack at it until I made something that works 99% of the time, but there must be someone who needed the same thing, and spent the time coming up with a much more elegant solution. Does anyone know of one?

• OpenGL ES 2.0 texture distortion on large geometry

  - by Spruce

  OpenGL ES 2.0 has serious precision issues with texture sampling - I've seen topics with a similar problem, but I haven't seen a real solution to this "distorted OpenGL ES 2.0 texture" problem yet. This is not related to the texture's image format or OpenGL color buffers, it seems like it's a precision error. I don't know what specifically causes the precision to fail - it doesn't seem like it's just the size of geometry that causes this distortion, because simply scaling vertex position passed to the the vertex shader does not solve the issue. Here are some examples of the texture distortion: Distorted Texture (on OpenGL ES 2.0): http://i47.tinypic.com/3322h6d.png What the texture normally looks like (also on OpenGL ES 2.0): http://i49.tinypic.com/b4jc6c.png The texture issue is limited to small scale geometry on OpenGL ES 2.0, otherwise the texture sampling appears normal, but the grainy effect gradually worsens the further the vertex data is from the origin of XYZ(0,0,0) These texture issues do not occur on desktop OpenGL (works fine under Windows XP, Windows 7, and Mac OS X) I've only seen the problem occur on Android, iPhone, or WebGL(which is similar to OpenGL ES 2.0) All textures are power of 2 but the problem still occurs Scaling the vertex data - The values of a vertex's X Y Z location are in the range of: -65536 to +65536 floating point I realized this was large, so I tried dividing the vertex positions by 1024 to shrink the geometry and hopefully get more accurate floating point precision, but this didn't fix or lessen the texture distortion issue Scaling the modelview or scaling the projection matrix does not help Changing texture filtering options does not help Disabling mipmapping, or using GL_NEAREST/GL_LINEAR does nothing Enabling/disabling anisotropic does nothing The banding effect still occurs even when using GL_CLAMP Dividing the texture coords passed to the vertex shader and then multiplying them back to the correct values in the fragment shader, also does not work precision highp sampler2D, highp float, highp int - in the fragment or the vertex shader didn't change anything (lowp/mediump did not work either) I'm thinking this problem has to have been solved at one point - Seeing that OpenGL ES 2.0 -based games have been able to render large-scale, highly detailed geometry

• Boat passing under a bridge in a 2D tile based RTS

  I'm writing a 2D tile based RTS. And I want to add a 'pseudo 3D' feature to it - bridges over the rivers. I havent't start any coding yet, just trying to think how it fits the collision detection model. A boat passing under the bridge and a unit moving over the bridge will eventually occupy the same cell on the map. How to prement them from colliding? Is there a common approach to solve such a problem? Or I need to implement a 3D world to do this?

• How to make Box2D bodies automatically return to a initial rotation

  - by sm4

  I have two long Box2D bodies, that can collide while moving one of them around with MouseJoint. I want them to try to hold their position and rotation. Blue body is moved using MouseJoint (yellow) towards the Red body. Red body has another MouseJoint - Blue can push Red, but Red will try to return to the start point thanks to the MouseJoint - this works just fine. Both bodies correctly rotate along the middle. This is still as I want. I change the MouseJoint to move the Blue away. What I need is both bodies return to their initial rotation (green arrows) Desired positions and rotations Is there anything in Box2D that could do this automatically? The MouseJoint does that nicely for position. I need it in AndEngine (Java, Android) port, but any Box2D solution is fine. EDIT: By automatically I mean having something I can add to the object "Paddle" without the need to change game loop. I want to encapsulate this functionality to the object itself. I already have an object Paddle that has its own UpdateHandler which is being called from the game loop. What would be much nicer is to attach some kind of "spring" joint to both left and right sides of the paddle that would automatically level the paddle. I will be exploring this option soon.

• Formula for three competing heroes, each has one they can beat and one they're beaten by

  - by Georgiadis Abraam

  I am trying to design a game for a project I have, The main idea is: 3 Types of heroes 3 Stats per hero There are no levels involved so the differences must be located on stats. Fight logic - The logic of fight is that type1hero has good chances winning type2hero, type2hero has good chances type3hero and type3hero has good chances winning type1hero. For over a week I am trying to find a stats based formula that will allow me to fix this but I can't, I was meddling with numbers yesterday and it was decent but I can't extract the formula out of it. Could you please guide me or give me hints on how should I start creating formulas on a Non lvl game that fulfills the fight logic?

• How to loop section from a song correctly?

  - by Teflo

  I'm programming a little Music Engine for my game in C# and XNA, and one aspect from it is the possibility to loop a section from a song. For example, my song has an intropart, and when the song reached the end ( or any other specific point ), it jumps back where the intropart is just over. ( A - B - B - B ... ) Now I'm using IrrKlank, which is working perfectly, without any gaps, but I have a problem: The point where to jump back is a bit inaccurate. Here's some example code: public bool Passed(float time) { if ( PlayPosition >= time ) return true; return false; } //somewhere else if( song.Passed( 10.0f ) ) song.JumpTo( 5.0f ); Now the problem is, the song passes the 10 seconds, but play a few milliseconds until 10.1f or so, and then jumps to 5 seconds. It's not that dramatic, but very incorrect for my needs. I tried to fix it like that: public bool Passed( float time ) { if( PlayPosition + 3 * dt >= time && PlayPosition <= time ) return true; return false; } ( dt is the delta time, the elapsed time since the last frame ) But I don't think, that's a good solution for that. I hope, you can understand my problem ( and my english, yay /o/ ) and help me :)

In the beginning it's moving slowly and then it accelerates gradually and at the end it's moving really fast. What should i do to get rid of this acceleration?
