any tips or insights on how to create client sided hostiles
in my game there will be a lot of hostiles so i need something that can work on a large scale
If I’m understanding your question correctly:
You can create the hostiles as you usually would, however you would need to do so inside a LocalScript. LocalScripts only affect things for the client they are bound to.
However, if the hostiles are only on the client it may be easy to exploit. The only way for the server to know what the player has done (for example how many kills they have gotten) is by asking the client. This goes against a fundamental principle in programming.
The client should ask the server to do something, not demand the server to do something. For example, if an exploiter joins the game they could tell the server “Hey, I killed 100000 hostiles. Give me my rewards” and the server would have no way to know if this was correct or not.
The servers only defense is Sanity Checks in that case.
