while loop not restarting on save load

[lordfrith 402]

hi folks

 

i've written a while loop to scan for nearby buildings as player moves around. on mission load everything is working beautifully but on loading a save game the loop doesn't continue.

 

the structure of the loop being spawned is as follows, in the mission init there is:

 

Quote

[param,param,param]call compile preprocessFile "LF_Init.sqf";

 

which has a bunch of variable/function defines and then at the bottom:

 

Quote

if (isServer) then {
        sleep 1;
        _start = [param,param,param] execVM "LF_loop.sqf"
};

 

which contains the while loop:

 

Quote

/////////////////////////lOOP////LOOP////LOOP////LOOP////LOOP////LOOP////LOOP////LOOP////LOOP////LOOP////LOOP////
params ["param","param","param"];

        sleep 1;
        while{true}do{
                _call = [params] call LF_fnc_stuffAndThings;
                etc;
                sleep 1;
        };

 

is there anythings obviously wrong with the scheduled/unscheduled environment thing here? I'm a bit hazy on it still... i thought when the save is loaded the while loop state would be loaded and continue

This was an interesting read from arma 2OA and might be able to help you. May not apply to arma 3.

do you have "disableSerialization" anywhere?

i don't think so, save/load seems to work ok for other stuff, this is defined in description.ext right? i'll check in the editor settings too, i wouldn't have it in any of my scripts as being save compatible is a big part of what i'm trying to do.

 

as seen in my example above there are unscheduled function calls within the while loop, would this be causing it? once you've run something in a scheduled environment does everything within that function also have to be unscheduled?

cheers, i was actually reading that very thread looking for answers. When AZcoder says:

The state of this thread gets saved with the mission, so when you reload, the thread keeps running. When you load from a save, the last sleep command will still run,

 

thats what made me believe it was possible...

 

thanks for your answers folks :D

 

P.S. as a test i removed the while loop and just spawned the function again as it ends, this works ok with save load so i've botched it to work but would be nice to figure out this while loop thing...

 

EDIT : can anyone think of a bomb proof example of a save proof while loop i could have a look at? i've been checking through other scripts i have but not found an obvious good example

No https://community.bistudio.com/wiki/disableSerialization

That script command executed in your script or any script you "call"

What are "unscheduled function calls" ? Your script is scheduled.

What? Scheduled code runs scheduled. I don't understand what you mean.

sorry dude, i have no background in this stuff so i find it real hard to describe what i'm trying to do correctly, getting this far has been a bit of a journey ;)

 

i have read the page you linked before and.... soooort of understood it

so the script is scheduled as its execVM... but within that i'm using unscheduled 'call' to start other functions... this isn't an issue then?

unscheduled 'call'

"call" is not unscheduled. it doesn't change the scheduled-ness. A call inside unscheduled stays unscheduled. A call inside scheduled stays scheduled.

 

Only issue I can think of is you having disableSerialization somewhere.

hmm well i don't but i think given our discussion above i need to go back and relearn a bunch of stuff anyways, thanks for your helps, if i get this sorted i'll post back here

SOLVED: switching the functions in the while loop from 'call' to 'spawn' seems to allow saving and loading to work as intended

i.e.

Quote

/////////////////////////lOOP////LOOP////LOOP////LOOP////LOOP////LOOP////LOOP////LOOP////LOOP////LOOP////LOOP////
params ["param","param","param"];

        sleep 1;
        while{true}do{
                _spawn = [params] spawn LF_fnc_stuffAndThings;
                etc;
                sleep 1;
        };

@Dedmen yeah i'm confused too given what you've just told me
