Target appearing and disappearing
I want to make objects ( in this case targets ) to appear on the screen and disappear after a certain time, however I want to be able to click on them to make them disappear as well. I ran in to a problem that if I destroy the object that the script has spawned and do it fast enough so that the spawner can't produce enough targets for me to click, it shows an error that there's nothing to instantiate (so I destroy the targets faster than the spawner can spawn them). Here's the code that I've written so far. (To destroy the target I have a js script on the dots that spawn)
public GameObject dot; float randX; float randY; Vector2 whereToSpawn; public float spawnRate = 2f; float nextSpawn = 0f; public float lifetime;
void Update()
{
if (Time.time > nextSpawn)
{
nextSpawn = Time.time + spawnRate;
randX = Random.Range(-2f, 3f);
randY = Random.Range(0f, 8f);
whereToSpawn = new Vector2(randX, randY);
dot = Instantiate(dot, new Vector2(randX, randY), Quaternion.identity) as GameObject;
Destroy(dot.gameObject, lifetime);
THE ERROR:
MissingReferenceException: The object of type 'GameObject' has been destroyed but you are still trying to access it.
