Removing point leaks in conditions

[darwin]

I want a trigger that fires when someone selects a unit and their hero is very close to that unit. I did the selection event, and as a condition I want to use the real comparison between triggering unit and hero. Will that cause a leak because of the "position of triggering unit" and "position of HERO"?

How do I set them to variables and delete them? Do I have to have the trigger fire every time anyone selects anything and then have an IF/THEN statement that skips it?

That would be it.

I wouldn't worry about that affecting performance.

Alternativly you need not make locations at all.

Simply get their X and Y positions, make one point the orign and use good old right angle triangle maths. h^2=x^2 + y^2. This infact is faster than the GUI method cause it involves generating locations and reading the X and Y from them whereas you can read them directly.
