[Trigger] Detecting if unit is null or not

[Koltira]

So i have this trigger which picks a single unit that meets some conditions, but then later in the trigger i need to detect whether any units met those conditions or not.

You could check if (Your_unit is equal to (No unit)). That basically checks if your_unit == null.

Also, you should consider using only one language for your stuff. Not a mix of both languages, as some words are written same in both languages, but in each language they mean something different (e.g. list = array in english or leaf in czech. Then it would be confusing if you had name e.g. "myList" right?)

Thanks for the reply, i haven't even considered that

as for the language, i'm trying to get used to only english but i've had translated warcraft for 10 years so it's hard getting used to
