When using an alert script for players entering a certain trigger volume, inserting (players) works perfectly, however I get an error that says that using "player0" or "player1" is not a valid object name. How do I set this up to alert only when the enemy player enters a trigger volume located around your base?

Use:

(script static unit player0
	(unit (list_get (players) 0))
)

to refer to the first player and

 (script static unit player1
	(unit (list_get (players) 1))
)

to refer to the 2nd player. Well, that's what I remember off the top of my head anyway.

EDIT: Also, put these scripts before all your other scripts. So the next time you want to refer to the 1st player, you just put (player0), etc.

When compiling scripts in the map, it still says that player0 is not a valid object

Here is the script:

(script continuous balert1
	(sleep_until (volume_test_objects balert_tvol1 (player0)) 15)
	(sound_looping_start "sound\alarm\coldsnapwarning" none 1)
	(sleep_until (not (volume_test_objects balert_tvol1 player0)) 15)
	(sound_looping_stop "sound\alarm\coldsnapwarning")
)

Ok, it seems to work now after I put () around the player0 and player1, however, it can't tell the difference between player0 and player1. For the script where an alert is supposed to sound when player0 enters player1's base perimeter, if you change sides, and are now player1, you still set off the alert.

If you are the only player in the game, you are always (player0) no matter what side you're on. If somebody were to join the server with you (assuming this is MP), they would be (player1).

Edit: actually, scratch that. If somebody were to join a server with you, you would become (player1) and they would be the new (player0). The number system is really weird with the (players) variable, just letting you know.

And unless you wish to set up a complicated spawning system, there is no way I know of to determine who is on your team and who isn't.
