I was wondering how to get a unit to spawn a certain distance away from another unit.
Like say for example player 1 control a marine.
Every 'x' number of seconds a zergling appears in front of it.
I want to be able to do this using triggers rather than preplacing units on ground.
And I know I can't the zerglinf at a location constantly following the marine, because then It would create the zergling right uner or next to it.
I just need the zergling to spawn a certain distance away from the marine
no matter where in the map as long as it can be created.
Is there a way possible?

Yes, download my Tests Compilation and play the Mobile Grids map in it, it will show you how to do just what you want. If you need more explaination, or the link doesn't work, post back

Yeah... it gave me an error saying "file is no longer on mediafire"
and before that I downloaded a file with nothing in it except more errors :[

Here's the non-direct link, the link at my website worked last night

Woot, over 240 downloads!
