simple loop not working

[Triggerhappy]

here's the loop:

Code: [Select]

_i = 0
all_objects = []
_o = (object 0)

#loop
?(isnull _o): exit
all_objects = all_objects + [_o]
_i = _i + 1
_o = call format ["(object %1)",_i]
~.0001
goto "loop"
what its supposed to do is create an array of all the map objects

but a hint format shows that the array is empty.

my only thought is that there may be no object 0. if that's the case, the script exits and the array remains empty.

is there an 'object 0'?

[Triggerhappy]

yes, i tested that on nogova
came up with some kind of house or something, anyway, i didn't get any kind error so there is definitely an object 0



another thing i just thought of: what if all objects are considered null by the game engine?
its a long shot but something is making it exit

Add

hint format ["%1", all_objects
~3

into the loop to give you a better idea of what's happening.

If the array is coming up empty then the problem is right at the start since object 0 (which does exist IIRC) is not being added to the array.

i do have a hint format (in a radio trigger) that i used to find out what was in the array.  I ran the script (called it) form the init.sqs and it shouldn't run for more than a few seconds

the hint i get is:
[]

so i don't know whats happening

odd but i think that was the problem, or something similar

by checking whether it was == to itself instead of whether it was null, the loop works fine.

quite odd indeed
