Description 描述

OnTriggerStay is called almost all the frames for every Collider other that is touching the trigger.

每当碰撞器从进入触发器，几乎每帧调用OnTriggerStay。

This message is sent to the trigger and the collider that touches the trigger. Note that trigger events are only sent if one of the colliders also has a rigidbody attached. Trigger events will be sent to disabled MonoBehaviours, to allow enabling Behaviours in response to collisions.

当碰撞器接触到触发器时，这个消息才发送给触发器和碰撞器。注意，如果碰撞器有附加的刚体，触发器事件才发送。触发器事件也发送给禁用的MonoBehaviours，允许启用Behaviour来相应碰撞。

Note: OnTriggerStay function is on the physics timer so it won't necessarily run every frame.

注意：OnTriggerStay函数是基于物理计时器，因此它未必每帧都运行。

也就是说OnTriggerStay是在每一个Time.fixedDeltaTime的时间节点上运行，不是Time.deltaTime的时间节点上运行

JavaScript:

#pragma strict
// Applies an upwards force to all rigidbodies that enter the trigger.
function OnTriggerStay(other) {
	if (other.attachedRigidbody)
		other.attachedRigidbody.AddForce(Vector3.up * 10);
}

C#:

using UnityEngine;
using System.Collections;
public class ExampleClass : MonoBehaviour {
 
	// Applies an upwards force to all rigidbodies that enter the trigger.
	void OnTriggerStay(Collider other) {
		if (other.attachedRigidbody)
			other.attachedRigidbody.AddForce(Vector3.up * 10);        
	}
}
