Debugger Error:Invalid scope kind

Anyway, the problem with Haramanai's code is that he's passing an object using the "Var" keyword. Which is nonsense since objects are always passed by reference.

Here is code to reproduce it:

Type MyFloat
	Field value:Float
EndType

Local wrapFloat:MyFloat = New MyFloat
DebugStop 
Test( WrapFLoat )

Function Test:Int( afloat:MyFloat Var)
	Return True
EndFunction

Remove the 'Var' keyword from the function signiture and it works as expected.

This doesn't seem like it's your problem though (as far as I can tell from the source you just posted).
