在我的游戏中,我利用Cocos2D为猎物。 我现在试图执行重力,但我听到我不得不使用Box2D或Chispmunk。 我可以利用这些想法,但是在Cocos2D中是否有这样做的方法,任何人能否分享任何想法/守则,以便我能够尽可能利用Cocos2D补充一些简单的严重性?
感谢!
Its very easy using Box 2d and Chipmunk. Its inbuilt in cocos2d framework. Just when you start with the cocos2d application template(for iOS) select the Box2D/Chipmunk template. Its very easy. Inorder to start with some gravity you have to create a world and add gravity vectors to it. You have a very simple and detailed tutorial in http://www.raywenderlich.com/457/intro-to-box2d-with-cocos2d-tutorial-bouncing-balls
其导师教导你在可可2dBox2d框架中制造一种ball球。
First create a CGPoint variable called gravity and set it s x value to 0 and it s y value to some negative number.
CGPoint *grav = ccp(0.0f,-9.8f);
接着,在你的游戏中,就你的每一个 sp子职位而言,都只是利用了跳板。
sprite.position = ccSub(sprite.position,grav);
