Gani Scripting Problem & fix

[Admins]

There is something in gani scripts which can
slow down the game a lot if used wrong:

never use normal variables as loop counter
like for (i=0; i<2; i++) ...

The problem is that gani scripts are not allowed
to read or change normal variables, only
this. variables. So the i++ will never change i
and the loop will go 10000 times (internal
protection against bad scripters . So better use
for (this.i=0; this.i<2; this.i++) ...

I have seen that problem in some ganis we used
in Graal2002 (torch and lamp) and fixed it, now
some places don't lag so much when walking around
/ entering the level
