碰撞检测在Unity3D [英] Collision Detection In Unity3D

问题描述

我正在做3D格斗游戏。我有他们的动画的两个字符。我应用字符控制器和字符控制器脚本，我已经定制。我有两个按钮一移动farword和一个移动backword..And四个按钮播放不同的动画，就像打一个拳头，打腿等直到它的工作perfactly罚款。
现在我使用胶囊对象和他们的胶囊对撞机作为不同骨骼的孩子。像我已经放置一个胶囊对象与他们的对撞机的左手骨的孩子。骨骼移动，该对象将移动。
我也放置了capusle在第二个播放器的身体，我放置在头下，在腿上它的意思是它在胸部erea的地方。我也使用没有重力和onTrigger功能的刚性身体点击在所有胶囊obects ..现在我想，当我的第一个玩家手触摸第二个播放器主体在其中胶囊放置它会调用一个函数。但在脚本中不会调用。我不知道是什么问题。可以任何身体指导我。这是我的脚本

解决方案

我假设你既没有得到OnCollisionEnter也没有得到OnTriggerEnter的调用。

确保这些方法的脚本是在实际的GameObject，有collider-component。 / p>

OnCollisionEnter-Reference：

注意，碰撞事件只有在

总结：OnCollisionEnter只有在你真正使用物理学的时候才会被调用

如果你只想通过物理系统注册一个没有引起移动的命中，你可以使用OnTriggerEnter。
在这种情况下，刚体必须在移动对象上，并且至少有一个涉及的对撞机必须设置为isTrigger。

还要确保层设置为在projectSettings-> Physics中碰撞。

希望这有助于你。

I am working on 3D fighting game.I have two character with their animation.I have applied character controller and character controller script which i have customized. I have two button one to move farword and one to move backword..And four button to play different animation just like make a punch, hit a leg etc. Upto that its work perfactly fine. Now I have use capsule object with their capsule collider as a child of different bones. Like i have place one capsule object with their collider the child of left hand bone.SO where the bone move that object will move.. I have also place a capusle on the second player body which i place below the head and above the legs its mean it place in the chest erea. I have also used Rigid body having no gravity and onTrigger function clicked in all capsule obects.. Now i want that when my first player hand touch the second player main body in which capsule is place it will call a function.But in the script it will not call..I dont know what is the problem..Can any body guide me. Here is my script

public function Start() : void {

解决方案

Alright. I assume that you get neither the OnCollisionEnter nor the OnTriggerEnter call.

Ensure, that the scripts with these methods are on the actual GameObject, that has the collider-component.

OnCollisionEnter-Reference:

"Note that collision events are only sent if one of the colliders also has a non-kinematic rigidbody attached."

To sum up: OnCollisionEnter is only called if you actually use the physics system for moving the objects around due to forces, collisions etc.

If you want to just register a hit without it causing movement via the physics-system, you can use the OnTriggerEnter. In this case, the rigidbody must be on the moving object, and at least one of the involved colliders must be set to isTrigger.

Also ensure that the layers are set to collide in projectSettings->Physics.

Hope this helps you.
