I was pretty sure this script would work but it hasn't, I want the next area of AI to spawn when the play walks threw this trigger volume but it doesnt work:

(script dormant ai_spawn_2
(begin
(sleep_until (volume_test_objects v1 (players)) 15)
(ai_place human_defend_1)

)
)

v1 is what my trigger volume is named...

I also would like to know what the 15 means, I just added it cuz it was in a tutorial...

Use startup instead of dormant... I forgot what the 15 was for.

Dormant means it wont even attempt to start until another script (or dev) awakens it with the wake command. The begin is useless, and will slow your script by a whole 30th of a second. the 15 is useless, it is ment for picking timing for testing it, but ive never bothered since im fine with default settings.

(script startup ai_spawn_2
(sleep_until (volume_test_objects v1 (players)))
(ai_place human_defend_1)
)
