[vJASS] Make the first instance always go through...

[Chewii]

Hey there guys! I need some help here.
I think I've done this before but I really can't remember how...(im new to jass)
I want to make like a sort of a boolean which is false from the beginning, and first time this trigger runs it will always go through the if conditions. However it will turn to true and next time the trigger runs it wont go through the if conditions..

         local boolean boo = false
     if(boo == false) then
        set boo = true    
    else
        set boo = false
      endif

something like that but this doesn't work because it will always result in false..
To sum this up: False first time, true second, false third, true fourth and so on

Redeclaring local will always set its value to false so use a global.

Also can be simplified to

if boo then
    set boo = false
else
    set boo = true
endif
