I know this sounds nooby, but this is my first multiuser game. I cant seem to make the camera follow the clone when it spawns, and I have no idea what grabbing a link and transforming it means. Every time I try to make it follow the clone, I get a strange error. Could someone give me a script so that:
Instead of following new Prefab, when it spawns new Prefab(Clone) it would follow that instead. Help would be much appreciated.
More info:
Im trying to make a racing game. This is the script im using for the controls.
