If you mean after being killed, then yes, using
respawn = 4
will respawn you into the body of any AI that is alive
respawn=5 will respawn you into the body of any AI that is alive on your side.
Its possible to place these AI somewhere out of the way and teleport them to a different location when you want
Other alternatives i suppose are to exec an AI create script when you die etc etc
The COOpers will be better at answering how to do this
Adding Respawning
4 (or "GROUP")
- Respawn into any alive AI in the player's squad after respawndelay.
If noone is left then the player respawns as a seagull.
5 (or "SIDE")
- Exactly the same as number 4 (GROUP) - at least in v1.46.
Two pitfalls must be pointed out before you start testing:
1. Note that respawning will not work if you run the mission from the editor. You will have to Save and Export to Multiplayer, exit the Mission Editor, select Multiplayer, create a new server, select your mission, and test it.
