native functions

[legacy-segall]

Why do some native functions not have a number associated with them? For example:

Actor.uc

native(283) final function bool SetCollisionSize( float NewRadius, float NewHeight );
native final function SetDrawScale(float NewScale);

Just curious...

I believe the native number is only used either for stuff that needs to be very low overhead (called through a lookup table), or it's just ignored entirely by the compiler.

the number is indeed used for a lookup table, otherwise the function has to be found by searching for a function with that name.
