[Question] How to use public variables properly

[Graz 1]

I've been trying to initiate an an storm by using a public variable as a boolean.

It's for multiplayer, with JIP on a dedicated server. The server handles the probability of a storm occurring and the client executes the effects. It all worked perfectly without the variable, but now it's not returning anything. This is the first time I've use a public or global variable so I'm sure I've just made a rookie mistake! Here's the code:

mission init.sqf:

//Storm pulse
if (isDedicated) then {
    [] execVM "weather/storm_pulse.sqf";
};
//Storm
if (!isDedicated) then {
    [] execVM "weather/storm.sqf";
};
[/Code]

This is the storm_pulse.sqf

[Code]
//Storm testing
while {true} do {
sleep 120;
Grazstorm = True;
publicVariable "Grazstorm";
};
[/Code]

And the loop and call in storm.sqf

[u]This isn't the whole code, just the relevant parts[/u]

[Code]
[] spawn {
_delay = 3;
sleep 0.01;
while {true} do {
if (Grazstorm = true) then {
_delay setovercast 0.9;
_delay setrain 1;
_delay setfog bis_fog;
sleep _delay ;
};
};
};
//It's called again here
while {true} do {
if (Grazstorm = true)
then {
//A metric ton of code I've removed
};
sleep 0.2;
};
[/Code]

I have no idea how this isn't working!!! Squint didn't have any errors and the effects worked perfectly until I put in these checks. Does anyone know where I've ballsed up?

while {true} do
{    
         if ([color=#ff0000]Grazstorm[/color])  then 
        {             
           //A metric ton of code I've removed    
        };    
sleep 0.2;
};

Edit: forgot to say thanks for posting back :)

Is that different from = true? Or is it just a lot cleaner?

[lifted86 10]

it should be (Grazstorm == true) // not sure if this works

[iceman77 18]

No it shouldn't. What I posted is to check bool on a variable.

If you wanted to check for a false variable then use

If (!Grazstorm) Then { ... do some shit ...};

If you wanted to see if the variable (exists) then you can use

 If (IsNil "Grazstorm") Then {hint "the variable doesn't exist"} Else {Hint "The variable has been set and it exists"};

= sets/assigns (w/e) a variables value.

If you wanted to compare then use ==

= is assign value

== is equal to

If you'd had == the if condition would be

if (true == true) then {
//
};

Since your variable is a Boolean. Hence you only need to write the variable since you're checking its value.
