I've made a part and put this script into it,
function onTouched(Touch) game.Lighting.Ambient = Color3.new((200/255), (200/255), (200/255)) end script.Parent.Touched:connect(onTouched)
but it doesn't change the ambiance when I step on it in game. I tried using game.Lighting.Ambient = (200, 200, 200), but that doesn't work either. Does anybody know what to do to make this work? Thank you for reading.
