im reading polamees sp tutorial cus this is my first time making an sp, and i have a question, when it says to make this script:(ai_allegiance "player" "human"), does it mean like go into notepad and put the script in there or sompthing else

You can do it in-game using dev if you wish. Or you can 'make it so' using a script.

Heres a basic script:

(script startup test1
(sleep_until (volume_test_objects test2 (players)) 15)
(ai_allegiance player human
)
)

Basically when you enter the trigger volume entitled 'test2' it will ally the player team with the human team.
