How to make a Allied system

how do you make an allied system so that for example with acs weapons, people from team A can’t damage the people from team B because they are allies.

If you’re using toolbox weapons, you’ll need to modify them so they can only damage players that are not on the same team.

it depends heavily on the system of your entire combat system. use of CollectionService to add tags, having tables that the damage scripts can reference to figure out who is allied to who are all options. without any context to your current system not much help can be given
