I am sorry I don't know how to write code.
I am trying to make some triggers with jass.

I want it to be worked like this:
when a hero that is ally of player1 gets out of Test1, Test2, Test3,
I want to do some work on alive heroes left in the area where a hero left.

But somehow I never get any heroes in group g.
and is this leak safe?
I am using DisplayTextToForce to checking where the problem is.

And one more question, what is the difference between Filter and Condition?

Thanks

First of all there is no difference between Condition and Filter. However it's a common approach to use Condition for trigger Conditions and Filter for enumerations.
Inside your Filter function, replace GetEnumUnit() with GetFilterUnit(). Also use

 native UnitAlive takes unit u returns boolean

to check if a unit is alive.

Thank you.
I will try when I go home back.
Btw how do I make codes to be in code block just like you and all others do?
Mine is just plain text.
