i'm trying to use this script:

(script continuous set_marines_Pelican_ZONE
(begin
(if
(and
(= (volume_test_object ZONE Pelican) true)
(= (unit_get_current_flashlight_state Pelican) true)
)
(begin
(begin
(if
(and
(= (volume_test_object ZONE (ai_actors marines)) true)
(= Pelican_has_hog_number -1)
)
(begin
(unit_set_desired_flashlight_state Pelican false)
(set Pelican_has_hog_number 1)
)
)
)
)
)
)
)


which is supposed to test to see if there is a pelican in the trigger volume 'zone' and the ai encounter 'marines' in the 'zone'. for some reason, (probably i'm using it wrong) it gives me this response when compiling:

i expected a object, but this function returns a object_list.: (ai_actors marines)) true)

could any scripting incarnate help? any help is much appreciated!

Use (volume_test_objects) instead.
