i have a lot of get component lines in a part of my game. Is this inefficient?
GetComponent is indeed a slower process, but it depends on how you’re using it.
Are you literally calling it in the Update every single frame? If so, you should cache it.
Sometimes, you can’t actually get away from using it, but you can limit it.
That portion of code looks fine the way it is. However, it also depends on where it’s located.
