统一的游戏对象计时器

Question

我正在尝试制作一个有游戏对象（假设是一个球）的统一游戏，并且在分配的时间（5 秒）之后游戏对象消失了，代码中有任何线索吗？

Answer 1

The simplest way to achieve that is to use Unity's built-in Destroy() method.
You can pass your object and a timer (in seconds) as arguments.

Destroy(gameObject, 5); // destroys the gameObject after 5 seconds elapsed

Answer 2

Well, you could try to use the Invoke method, which will call the method you specify after some time.

void Start()
{
    Invoke("DestroyMyObject", 5);
}

void DestroyMyObject()
{
    this.Destroy(this.gameObject);
}

If you want to call some method repeatedly, you could use InvokeRepeating Here is the whole documentation:

Answer 3

You can use an coroutine for the timer. This is a bit more complicated than other answers, but it is good practice for using coroutines. For example:

IEnumerator DestroyObject(GameObject object, int time) {
yield return new WaitForSeconds(time);
Destroy(object);
}

If this script is attached to a controller or anything else that isn't the player:

public GameObject player;

//Wherever the player is supposed to be destroyed 
{
DestroyObject(player, 5);
}

If this script is attached to the player:

//Wherever the player is supposed to be destroyed
{
DestroyObject(this.gameObject, 5);
}
