Trouble with sendmessage
I've got this in a script attached to a rocket launcher: (FYI, Projectile is a public variable of type GameObject, I set it by dragging the prefab of a specific type of projectile to the inspector).
Instantiate(Projectile, transform.position + ProjectileOffset, transform.rotation);
Projectile.transform.LookAt(_target.transform);
Projectile.SendMessage("SetTarget", _target, SendMessageOptions.DontRequireReceiver);
This creates a projectile at the launcher location, points it at the target, and tries to let the projectile know who its target it.
In the Projectile GameObject's projectile script, I have this:
public void SetTarget(GameObject target)
{
Debug.Log("Setting target to " + target);
Target = target;
}
For some reason, this never gets called, even though the projectile is being created and "launched". Any ideas on why this method isnt getting called, or perhaps a different approach to take?
You're trying to SendMessage to the actual prefab. You need a reference to the instantiated clone that exists in the scene:
GameObject projectileClone = (GameObject)Instantiate(Projectile, transform.position + ProjectileOffset, transform.rotation);
projectileClone.transform.LookAt(_target.transform);
projectileClone.SendMessage("SetTarget", _target, SendMessageOptions.DontRequireReceiver);
As an aside, I'd recommend sticking to the convention of using lowercase for variable names and upper case for classes and types, because otherwise it gets confusing as to what you're referring to.
