Hello,

Here's one approach where t1 goes to a defined pos, and t2 does a  
random heading and random forward. If by any (bad)luck it is too  
close to t1, it will move again. This technique allows you to define  
how far apart the things should be at the beginning of the game (t3  
steps in my example).

to setup
t1, setpos [100 100]
t2, setpos [100 100]
rt random 360
fd random 100
if (distance "t1) < 30 [setup]
end
