Another question about conditionals.

Hai guys. Lot's of questions from me recently. Thanks in advance for your help.

Are the boolean operators in JASS short circuited?

i.e. if (someBoolVal || funcThatReturnsBool())

If someBoolVal is true will it evaluate the second and call the function?

Never mind. I realized i could test it myself. And the answer is, yes, it is short circuited.

Test Code:

//! zinc
library Test 
{
    function True() -> boolean
    {
        BJDebugMsg("true function called");
        return true;
    }
    
    function EscActions()
    {
        if (true || True())
        {
            BJDebugMsg("Obviously I will print");
        }
    }    

    function onInit()
    {
        trigger t = CreateTrigger();
        TriggerRegisterPlayerEventEndCinematic(t, Player(0));
        TriggerAddAction(t, function EscActions);
    }
}

Only "Obviously I will print" was displayed.
