keyword "constant"

chobibo	What is the difference between a timer declared as a constant from a timer declared normally? constant timer T1 = CreateTimer() and timer T2 = CreateTimer() OFF-TOPIC: Hey why does this function work and not give errors? JASS: public function StartTimers takes nothing returns nothing call TimerStart(Detector, 2.00, false, function StartTimers) call BJDebugMsg("Again?") endfunction

Vexorian	One will make the optimizer generate a bugged map script.

Pyrogasm	Meaning...?

chobibo	which one?

Deaod	i think Vex's Optimizer tries to inline constant functions and globals. So if you change a constant global during gametime, your map gets srewed up.

Malf	You can't change constant stuff. Hence the prefix *constant*

JASS:


globals
    constant timer t=CreateTimer()
endglobals

function aa takes nothing returns nothing
    call BJDebugMsg("expire!")
    call TimerStart(t, true, GetRandomReal(1,2), function aa)
endfunction

Becomes (after optimizer):

JASS:

function aa takes nothing returns nothing
    call BJDebugMsg("expire!")
    call TimerStart(CreateTimer(), true, GetRandomReal(1,2), function aa)
endfunction

Try to run "optimized" aa on your map, have fun...
