Question by DayyanSisson · Jul 13, 2012 at 06:23 PM · instantiatestartassignwhile

While Loop Not Assigning Array

I have t$$anonymous$$s w$$anonymous$$le loop in the Start function:

  int i = 0;
 
  w$$anonymous$$le(i < groupCount){
       patrollers[i] = Instantiate(AI, spawnPoints[i].position, spawnPoints[i].rotation) as Transform;
       i++;
  }

Well the AI's are being Instantiated, they just aren't assigned to the patrollers array. When I open the array, all the elements are empty. What am I doing wrong here?

Is patrollers an array of Transform?

Yes (indicated by the "as Transform" cast)

But if it was an array of something else then would all be empty was my thinking. The other problem would be if AI wasn't a Transform variable - your As Transform cast would return null.

AI is a GameObject variable. This first loop has to spawn all the enemies, which is why it's in the start loop.

You need to get the transform from the instantiated GameObject - Instantiate returns the type of the variable w$$anonymous$$ch is passed in.

    patrollers[i] = (Instantiate(AI, spawnPoints[i].position, spawnPoints[i].rotation) as GameObject).transform;
