    // The mesh goes red when the mouse is over it...
    void OnMouseEnter()
    {
        rend.material.color = Color.red;
    }

    // ...the red fades out to cyan as the mouse is held over...
    void OnMouseOver()
    {
        rend.material.color -= new Color(0.1F, 0, 0) * Time.deltaTime;
    }

    // ...and the mesh finally turns white when the mouse moves away.
    void OnMouseExit()
    {
        rend.material.color = Color.white;
    }
}

この関数はレイヤーが「 Ignore Raycast 」のゲームオブジェクトでは呼び出されません。

This function is called on Colliders marked as Trigger if and only if Physics.queriesHitTriggers is true.

OnMouseEnter can be a co-routine, simply use the yield statement in the function. This event is sent to all scripts attached to the Collider.
