I was thinking is it possible it have weapons that have color changing bitmaps like an assault rife that has a red or blue stripe depending on your team on it is it possible? or would i have to make spawns that make you start with red or blue weapons but that's just for those spawns and the spawns would have to be two weapons if i remember correctly. i am not making any maps i just wanted to know.

edit a bitmap for it, change the item_collection to another name
use the new item_collection to place the new weapon version.
done?

What i meant is like in gears of war where you would pick up a weapon and it would change color to the according team color of the weapon holder

there would be nothing stopping me ( a player on the blue team, because i hate the dam reds) picking up a red ar.

what does that have to do with what im talking about?

I assume you want red players only to wield red guns.
You can just do what ally said, make 2 item collections and make one red and one blue.

i think he wants the color to change to that team's color when the weapon is picked up.

I don't think its possible, youd have to make two item collections like Maniac said.
Unless you can do it in script, which i don't know how to do.

You could make the color'd portion part of your FP arms, and have your FP animations move it with the arm, and hide it for any other weapon (or, move that weapon's coloring object in)

Or, write a opensauce post processing, have that strip follow some absurd color you wouldnt natrually see, and have the post processing replace that color with your team color.

Vehicles are far more simple; you don't need to worry about FP or anything.

(script continuous warthog1ColorOfDriver
(if (vehicle_test_seat_list warthog1 "w-driver" (player_team_players 0)) (object_set_permutation warthog1 "" "red_variant") 
	(if (vehicle_test_seat_list warthog1 "w-driver" (player_team_players 1)) (object_set_permutation warthog1 "" "blue_variant")
		(object_set_permutation warthog1 "" "empty_variant")))
(sleep 10)
)

just have OS return a list of each team, if a red member is the driver, set the model to the red permutation. if a blue member is the driver, set the model to the blue permutation. If neither are there, put it to the empty variant.

Do it the same way the flag works. By team, it changes the color. I don't remember how, haven't worked with CE in ages. But it's the way CMT changes there plasma rifles, MP colored spartans, the flags, etc..
