Hi, today i come up with an idea for an Mod/Feature i want to test: a simple Label somewhere on the screen, that tells you based on your current velocity the distance you will need to break down to zero... but now here is my problem, is it possible to write a script that gets executed only on the client and is not attached to an entity? and also lets me work with some UI stuff? (I can't find some scripts that adds the normal HUD with materials, credits and so on. so i think that's get created directly from the Engine, right?) regards PatteKi
