I am not really sure how this is called but what I am trying to do is to make module that can be called like this workspace.Part:MyModuleFunction() how I could achieve this? Because I can’t find anything about this, and of course how to get that value workspace.Part. That’s all. I am asking, because I don’t deal with modules most of the time and I have no idea on how to that. I know plenty of things like RequiredModule.MyModuleFunction(workspace.Part) but not workspace.Part:MyModuleFunction().
