box2d

I've got a problem with CCFollow in Cocos2D-X. I want to follow my a Sprite, which is referred to a Box2D-Body. When i call this->runAction(CCFollow::create(playerSprite)); in the init method of my GameLayer, the lower left corner of my usual screen is centered on my device and although the emulator. May anyone help me with this issue ? :/ Best Regards, stotheg ССFollow is often not enough for your own purposes. One way out of this situation is to create your custom ССFollow action or adding the required logic in the game loop. Please read this article, there's a lot of useful information for

I have created a project with cocos2d 0.99.5 + box2d. When I rotate my iphone, Screen automatically rotated too. So the boxes Flew up into the ceiling. How to disable auto-rotation? plz In coco2d 0.99.5, the template creates a file called GameConfig.h, where you get to choose what system controls the app's rotation. The default is #define GAME_AUTOROTATION kGameAutorotationUIViewController Now take a look inside RootViewController.m, or whatever you've named it in your file. in the - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation method, you'll see a

I'm developing an engine and a game at the same time in C++ and I'm using box2D for the physics back end. I'm testing on different android devices and on 2 out of 3 devices, the game runs fine and so do the physics. However, on my galaxy tab 10.1 I'm sporadically getting a sort of "stutter". Here is a youtube video demonstrating: http://www.youtube.com/watch?v=DSbd8vX9FC0 The first device the game is running on is an Xperia Play... the second device is a Galaxy Tab 10.1. Needless to say the Galaxy tab has much better hardware than the Xperia Play, yet Box2D is lagging at random intervals for

I am making a skateboarding game with obstacles you have to jump over using box2D and AndEngine. I am trying to make it so that when the player collides with an object, the object is removed and an explosion is placed at the objects old position, however something in the sprite removal code is freezing my program causing it to end (not even a force close message it just closes itself and goes to my home screen) and no error/exception information appears in logcat so I have no idea what is causing it! Here are some code snippets- when I create the sprites/boundaries I attach a JSONObject to the

I'm writing an Android game using LibGDX and Box2D. I'm planning on adding a turn-based multiplayer feature to it. Now, if on both clients I step the Box2D world at the same rate with the same time steps and I start a simulation on both clients with the exact same initial parameters, when the simulations are over, will the final state of both simulations be exactly the same? In other words, is a Box2D simulation perfectly deterministic? If it's not, then that means every time a simulation is over, one client acting as a host will have to tell the other to throw away its final simulation's

I've just began to work with the Libgdx's Box2d Engine but i simply do not understand when the methods of the Contactlistener should be called. There is on the one hand "begin contact" and on the other "end contact". Where should i call them, to get the Number of of a certain fixture touching others? And how do I implement the Contactlistener ? A redirec' to a Tutorial would answer my Question. I didn't find anything while searching google. This one helped me a lot but it is written for C++ and does not refer to the implementation into a main-gamecircle. Thx for helping me ;) Here's a short
