hi is their any active camouflage scripts to replace the flashlight(basically q turns on and of)

Yes, there is.

(script continuous Cloak
(begin
(sleep_until (= (unit_get_current_flashlight_state (unit (list_get (players) 0))) true))
(object_create cloak)
(objects_attach (unit (list_get (players) 0)) "" cloak "")
(objects_detach (unit (list_get (players) 0)) cloak)
(sleep 1650)
(sleep_until (= (unit_get_current_flashlight_state (unit (list_get (players) 0))) false))
(sleep_until (= (unit_get_current_flashlight_state (unit (list_get (players) 0))) true))
(object_create cloak)
(objects_attach (unit (list_get (players) 0)) "" cloak "")
(objects_detach (unit (list_get (players) 0)) cloak)
(sleep 1650)
)
)

I DID NOT MAKE THIS. It was in a thread posted a while back on halomaps.

Cloak is the name of the active camo you need to have placed somewhere on the map. It doesn't have to be cloak, it can be anything you desire.

I believe 1650 is the time it takes to use the camo again. You can change that to whatever you please as well.

The only problem is that it says "Picked up an active camoflauge" whenever you pick it up. But a little string editing can go a long way...

Remember to set the camo pwerup time to 15 seconds or so, otherwise it will last for a full 45 seconds.
