Need assistance with destroying Gameobjects
I am making a endless runner type game, having problem with destroying platforms once its off my screen. Just want to clean up my hierarchy panel. Here is my platform script....
public Transform PlatformPrefab; private Vector3 _nextTileSpawn; void Start() { _nextTileSpawn.z = 12; StartCoroutine(SpawnPlatform()); }
void Update() {
}
IEnumerator SpawnPlatform()
{
yield return new WaitForSeconds(0.5f);
Instantiate(PlatformPrefab, _nextTileSpawn, PlatformPrefab.rotation);
_nextTileSpawn.z += 4;
Instantiate(PlatformPrefab, _nextTileSpawn, PlatformPrefab.rotation);
_nextTileSpawn.z += 4;
StartCoroutine(SpawnPlatform());
}
}
I noticed that you are not actually destroying the game objects. What have you tried ? And why are you running the same 2 lines of code twice ? I can show you an example of how to write a simple script to do this, and you don't really need to use Coroutines. I feel a lot of people use them when starting out because it has the function WaitForSeconds(...), which is what most people want. The same can be achieved without Coroutines.
This below is untested code, but i hope it gives you an idea of how to handle the problem. Instead of a coroutine i just used a timer to simplify things. The timer will run and each time the timer runs out we create a platform. When creating a platform we save a reference to it, so we are able to destroy it later. At the moment I used an arbitrary amount of maximum platforms. I hope the comments will help you out with anything that isn't clear. The most important part of this, is to save a reference to your created objects (in an array or list...), so you can access them later.
public Transform platformPrefab;
public Vector3 nextTileSpawn;
//A list to hold all the instantiated platforms.
public List<GameObject> activePlatforms = new List<GameObject>();
//How many platforms can be active at once?
public int maxPlatforms = 3;
//Timer
public float timerValue = 0.0f;
public float timerMax = 0.5f;
public void Start()
{
//Some conditions here...
gameRunning = true;
}
public void Update()
{
//Increment the timer
timerValue += Time.deltaTime;
//Has the timer expired?
if(timerValue >= timerMax)
{
//Reset the timer
timerValue = 0;
CreatePlatform();
}
}
public void CreatePlatform()
{
//First create a new platform and add it to the list.
activePlatforms.Add(Instantiate(platformPrefab, nextTileSpawn, Quaternion.identity));
//Increment the position for the next tile.
nextTileSpawn.z += 4;
//Check how many tiles are active now, if more than allowed, remove the oldest one.
if(activePlatforms.Count > maxPlatforms)
{
//To many platforms, remove the first one.
GameObject p = activePlatforms[0];
//Remove from the list.
activePlatforms.RemoveAt(0);
//Destroy the object.
Destroy(p);
}
}
