我试图让玩家无法从左侧和右侧通过平台,并让玩家停在平台之上。到目前为止,我所有的碰撞事件都是左右两边,但右侧不起作用,剩下的就是窃听。我无法弄清楚如何做一个平台游戏的基本碰撞,任何人都可以给我一个工作解决方案?Java平台游戏冲突

@AndrewThompson我已经创建了超过4个线程已经在这个论坛上,我已经尝试了所有可能的解决方案,但它总是或者不好或者做我想做的事情的相反。 – 2013-04-21 14:17:51
我链接的来源(这是一个SSCCE顺便说一句)在这里坚如磐石。 ***赞成,已经创建了一个SSCCE!***如果没有,我投票结束为“不是真正的问题”。 – 2013-04-21 14:20:35
