Variables

Ok I'm a bit new to spellcaster sys and JASS so I have a question. I see some of the examples use the same global variables in different triggers. How come the spellcaster functions don't collide seeing how you could use two different spells with the same variable in the same time?!

in some of the triggers they aren't globals, they act as globals.

But as long as there aren't [waits/actions that may trigger other triggers that use the global] a global can be used safely in many triggers
