[CLEO-Q] Function within a function?

[Adler]

Saw this in the Funny Picture Topic a while back. The humor aside, it precisely and unfortunately depicts a circumstance which parallels a fear that has been inside me for quite some time:

 

 

I heard there were some... complications with negative variables in gosubs and I was wondering if scm_func's might have some problem too, which leads me to the question, "is it possible to call an scm_func from within a called scm_func (possibly deeper), and what are the problems associated with this?"

is it possible to call an scm_func from within a called scm_func (possibly deeper), and what are the problems associated with this?

It is indeed possible to call a scm-function in a called scm-function. It is regular used in object-oriented programming for example. Wesser uses call scm-func in functions quite often.

This is a script made on the request of a member: Coordinates tool

 

As you can see the functions are called within other functions in order to shorten the code.

 

hope that answered your question.

 

EDIT:

 

The only problems that can occur if something is returned and immediately used as part of further operations. checking the value before or after returning is always a good idea to prevent such exceptions.

0AB3 (function) limit:

call up to 1023 levels

 

gosub (part of project) limit:

call up to 8 levels

 

Got it?

Hey thanks guys, and Fastman: haha what happens after 1024 levels?

GTA SA crashes and you must kill gta_sa.exe process.
