How is this function passing only second/third parameters?

Help and Feedback Scripting Support
#1

Im looking over this code and its confusing me:

	function ObjShadow.Debris(Type45, Type46)
		if not ObjShadow then
			return
		end
		if not ObjShadow.Parent then
			return
		end;
		task.spawn(function()
			wait(Type46)
			if ObjShadow then
				ObjShadow:Remove()
			end
		end)
	end

because, while it works, it is only called with a single parameter

Debris(0.2)

There Are several Examples of this

Yes I know about setting default parameters, but there are none anywhere in the script

#2

I don’t know what the Type45 parameter is for, but if you call wait(nil), It won’t error.

I don’t think it is actually passing the Type46 parameter as Type45. The function would work with both parameters as nil.

#3

Could you send the whole script?

#4

It matters if it’s called like obj.Debris() or obj:Debris(). Read up on table-calling in the manual to see how it works.
