problem hud.size

[Tally]

yes , is a TallyMod function() this is a beautiful shot to reduce many code line , this hud.size allocated in the memory of a server with many huds
would not be a problem?

When all elements have been destroyed, and you use the method again, it resets the array:

if( !isDefined( self.txt_hud ) ) self.txt_hud = [];

So, no: it wont affect server memory.
