How do I get this All-Seeing Sentry to only attack enemy team members?

Hello! I'm trying to edit this script so that this doesn't target allies and doesn't allow you, the owner of the sentry, to target your allies.

Im not going to go indepth since it has 310 lines and i dont wanna read them but just do if whatever variable ya used to get player.Character.Torso.BrickColour = "red" then assuming you changed the torso to red for certain team make the damage 0 else run t normally ik it wont help you much but it will give you an idea
