I am trying to Destroy and object based on the location on the z axis.

I want to destroy a Game Object when it reaches a certain position on the z axis. Will this work?

if(transform.position.z == -30)

I can’t seem to figure it out. Do I need to build a script calculating the distance traveled for it to work properly?

Theoretically yes. The problem with doing it that way is that if it jumps past -30 without hitting it it won’t get deleted. Try using (transform.position.z <= -30) instead

Just use this:

if(transform.position.z >= -30){

You can’t use " == " because if the frame do not hit the “30Z” the object won’t be deleted.
