Frustration with this jass script

[thevoden]

I am getting this message everytime I use this custom spell in my map

"Double free of type: jData"

Here is the Jass Script

I cannot seem to find where I would remove that message.

Here are the other 3 triggers that seem to compliment it:

//Just needs to be copied into your map if you don't already have it.

        endif
     return cs_array<i>
    endfunction
    
endlibrary</i></i>

//Just needs to be copied into your map if you don't already have it.

library CSSafety

    globals
        private timer array T
        private integer N = 0
    endglobals

    
    function NewTimer takes nothing returns timer
        if (N==0) then
            return CreateTimer()
        endif
    set N=N-1
    return T[N]
    endfunction


    function ReleaseTimer takes timer t returns nothing
        call PauseTimer(t)

            set N=N+1
        endif    
    endfunction

endlibrary

function InitTrig_CSSafety_Copy takes nothing returns nothing
endfunction

And for some odd reason, if I disable this trigger below; it won't let me save my map correctly.

I'm not that familiar with JASS, but seems quite weird to me that you first destroy the jD thing and use it after that. And anyways, there's another section for JASS problems: http://www.thehelper.net/forums/forumdisplay.php?f=109.

 

[Flare]

Try moving the "call RemoveUnit (jD.jUnit)" above the "call jD.destroy ()" (since the struct is destroyed, i cant see how you can remove the unit contained within the destroyed struct.

To me, it doesn't sound like that would give the error you said, but I can't say for sure. Just try it

 

[Zedzy]

This should be in the JASS sub-forum.
