如何在Unity3d中暂停GameObject几秒钟并在几秒钟后取消暂停

Question

I need the gameobject to pause on its own in my scene for 7f or 8f and un-pause at 2f on its own. The script I have is letting my pause by key. Here is my script :

{

 sing UnityEngine; using System.Collections; public class star : MonoBehaviour { GameObject[] pauseObjects; void Start () { pauseObjects = GameObject.FindGameObjectsWithTag("Player"); } void pauseGameobject() { if() { start coroutine("wait"); } } public ienumenator wait() { time.timescale = 0; yield return new waitforsceonds(7); time.timesale = 1; } void pauseGameobject() { if() { start coroutine("wait"); } } public ienumenator wait() { time.timescale = 0; yield return new waitforsceonds(7); time.timesale = 1; } 

}

It's not too clear what you mean by pause on it's one, however I'm going to answer broadly, to try and help you.

If you whant to pause a single game object externally you can deactivate it and activate it accordingly with this code: gameObject.SetActive(false);

Instead if you want to pause the game object internally you can make a bool and in the update test wether or not it's true:

using UnityEngine;
using System.Collections;

bool update = false

public class ActiveObjects : MonoBehaviour
{
    void Start ()
    {
        //Do stuff
    }

    void Update ()
    {
        if(update){
            //Do stuff
        }
        //decide wether or not to pause the game object
    }
}

If you want to pause the game you can set the Time.timeScale to 0 , or just pause all game objects.

Here you can find how to make a timer, all you need to do is count down a variable using timeLeft -= Time.deltaTime; .

Hope I helped you,

Edit: Ok, here is the script, keep in mind I have no way to test it ;)

using UnityEngine;
using System.Collections;

public class star : MonoBehaviour {
GameObject[] pauseObjects;

public float timer = 7;

float t = 0;
bool pause = false;

void Start () {
    pauseObjects = GameObject.FindGameObjectsWithTag("Player");
    t = timer;
}



void Update() {
    if(pause){
        if(t<0){
            t=timer;
            pause = false;
            time.timescale = 1;
        }else{
            t -= Time.deltaTime;
            time.timescale = 0;
        }
    }
}

You can use coroutines to insert delays in the update() loop. Coroutines use generators, which "yield", rather than functions/methods which "return". What this allows for is code that operates asynchronously while still being written in a linear fashion.

The built in coroutine you're most likely looking for is WaitForSeconds . To start a coroutine you simply call StarCoroutine() and pass in any method of type IEnumerator . This method will yield periodically. In the following example, WaitForSeconds(5) will yield after 5 seconds. Fractions of a second can also be used, represented by floats, for example 2.5 would be two and a half seconds.

using UnityEngine;
using System.Collections;

public class WaitForSecondsExample : MonoBehaviour {
    void Start() {
        StartCoroutine(Example());
    }

    IEnumerator Example() {
        Debug.Log(Time.time); // time before wait
        yield return new WaitForSeconds(5);
        Debug.Log(Time.time); // time after wait
    }
}
