Assign Transform from Hierarchy to Prefab script

Questions & Answers

Hey Everyone

I'm just getting started with Unity, right now I'm working on an iPhone project to learn the basics.

I am having some trouble with script variables though, and I'm sure it's just that I am learning as I stumble through each aspect. I have an enemy game object which has a script attached to it for the AI. This AI currently just tells it to chase a transform variable, which I then dragged my Player transform into. So everything seemed to be working great with the single enemy.

I then created an enemy prefab from the original, and setup a sphere collider to spawn a new prefab enemy when the player enters it. The problem is that the enemy prefab's AI script does not have the player transform assigned, so he just stands there after being created. I tried assigning the player transform as the default value, but this isn't allowed.

I know I must be missing something, and perhaps I'm going about this wrong. Any suggestions would be greatly appreciated.

Thanks!

After you instantiate a prefab you can save a reference to that instance, then get the enemy script component of the new instance (`EnemyScript` in the example below) and access any public variables or methods.

Javascript:

var newEnemy : GameObject;
newEnemy = Instantiate(prefab, position, rotation);

var enemyScript : EnemyScript;
enemyScript = newEnemy.GetComponent(EnemyScript);

enemyScript.targetTransform = transform;
