OR operator not working? - Fuiba - 03-01-2015
Hi guys. As you well know I've had problems with the mission ending triggers before. I've been banging my head against the wall for a couple of hours because my mission doesn't end.
So I decided to try if there was some bug about. Tried this with no mods just to make sure:
-Fresh map in the editor, VR map.
-Place one player unit.
-Place the first trigger, activated by Radio Alpha. On activation: a = 1; player sidechat "A triggered";
-Place the second trigger, activated by Radio Bravo. On activation: b = 1; player sidechat "B triggered";
-Place the third trigger, condition: a == 1 OR b == 1;
-On activation on the third trigger: player sidechat "A OR B triggered";
Now the third trigger fires ONLY when the first AND the second trigger have fired. Is this some Arma flavor on common logic or am I missing something?

It's because a and b aren't defined before you define them by Alpha/Bravo trigger. I had the same result as you until I added "a = 0; b = 0" in my unit's init line to define a and b.
AFAIK ArmA3 cracked down on undefined variablesÂ
;D

FFS I'm dumb
Thanks!Edit: no, I take that back! I'm not that dumb. Arma shouldn't even care about the right side of the expression as long as a == 1 holds true.
Re: OR operator not working? - Outlawz7 - 03-01-2015
But the right side of the OR isn't true or false, it's undefined.
Quote:a: Boolean - Test condition or variable that returns Boolean.
b: Boolean - Test condition or variable that returns Boolean.

Oh, right. I guess I automatically assumed that it used lazy evaluation. I don't think I've never used a programming/scripting language that works like this.

did you try a = true

It does, read the linked BIKI. It's just my guess than it wants both sides of OR to be either true or false, not something else.

Yeah, I did, thanks
The BIKI has the syntax for lazy evaluation, too.
