3.0版本2d物理碰撞怎么监测啊 小白求大佬指教

求大佬指教

2.0怎么撞，3.0就怎么撞

[huruiamy (Ari_Amy)]

2.0的我也不知道呀 才学cocos一天

[317529039 (let MyWife = new DoubleWife() But I want more wife -Harem 3000 girls)]

去看文档啊

[huruiamy (Ari_Amy)]

我就是看了这个文档没有效果 所以来请教大佬

你把你要碰撞的东西加了碰撞包围盒了没有？还有记得分组

1. 需要先在 rigidbody 中 开启碰撞监听 ，才会有相应的回调产生。

开启物理系统

物理系统默认是关闭的，如果需要使用物理系统，那么首先需要做的事情就是开启物理系统，否则你在编辑器里做的所有物理编辑都不会产生任何效果。

cc.director.getPhysicsManager().enabled = true;

是这样吗

碰撞器记得分组

[huruiamy (Ari_Amy)]

3.0的物理系统不是默认开启的嘛

代码贴出来

问一下你这些节点有大小吗？

有加collider碰撞组件吗

onBeginContact的参数是要传入碰撞的两个物体吗

[317529039 (let MyWife = new DoubleWife() But I want more wife -Harem 3000 girls)]

let rigidbody=this.getComponent(RigidBody2D)
rigidbody.enabledContactListener = true;
把这句加上，开启碰撞回调监听

[317529039 (let MyWife = new DoubleWife() But I want more wife -Harem 3000 girls)]

还有注册回调

你还是看文档去吧，3.0的文档

并不会出现空的
