KK.
give both lights the same name,(X).
Place a triggerzone and set it's main AI,(right click after placing it),to Plrinzoneactivateused.fpi.
Give green light this script:
;CoffeeGrunt Script
;Header
desc = Light Toggle (Off By Default)
;Triggers
:state=0:state=1
:state=1:state=2,lighton
:state=2,activated=1:lightoff, state=0
;End Script
And the red one this:
;CoffeeGrunt Scripts
;Header
desc = Light Toggle (On By Default)
;Triggers
:state=0:state=1
:state=1:state=2,lightoff
:state=2,activated=1,lighton
;End Script
Any Problems, just post back.
