I'm trying out Baddos suggestion first, but I've run into a problem.
I've got as the begining of a script:
tent1 setpos[getpos sf1 select 0, getpos sf1 select 1, 0]
Where tent1 is the tent and sf1 is the groups leader.
How do I get the tent to appear, say for example, 3m to that guys left, instead of exactly where he is standing?
