Problem with destroying instanced objects (23353)

[system]

I want to instantiate an object and whenever I instantiates a new object I want objects who share the same tag with the new object to be destroyed. I got the following lines of code

instance = Instantiate(Resources.Load(targetModel)) as GameObject;
Destroy(gameObject.FindWithTag(instance.tag));

The problem as you might see by looking at the code is that the instance is destroyed right after its been made. I always want the latest instance to remain.

I tried to switch places like below, but then I get this error: “UnassignedReferenceException: The variable instance of ‘mousePosition’ has not been assigned.”

Destroy(gameObject.FindWithTag(instance.tag));
instance = Instantiate(Resources.Load(targetModel)) as GameObject;

So how do I solve this problem?

You can’t use instance.tag because it was not assigned yet. Replace it with another variable containing the tag:

  Destroy(gameObject.FindWithTag(targetTag));
  instance = Instantiate(....

You must define previously the tag you want to kill in the targetTag variable.
