This is an example map of how to make 2 teleports that swap destination targets each 20 seconds.
Lets say you have teleport A and B and exits E1 and E2.
This setup randomly swaps between two exits.
It works like this:
There are 2 entity groups, one sets targets, other one activates.
A -> E1 | A -> E2
B -> E2 | B -> E1
And an system ive got from Atom The Mad Carrot, it randomly strikes swap activators (buttons).
Env_beam and targets.

Cool
Your going to use it in your map?
Nice example!
=)
I will try to make a better, and a more complex example in the future.
And also an example that shows hot to use Atoms (Muzzleflash) random generator to randomly activate stuff (which can be pretty cool to see).
