****Hi! I’m a new member here! I was working on a new project known as “Combat Shooter” but the business isn’t going well so I ended up leaving it behind. I only know how to change the behavior on a part with a script and I was looking up for gamepasses with a click detector in it on the internet but none of it seems to work for me 
here is the Color changing script on a part
next is the click detector script
Thank you

Please provide more information about your problem. What methods have you tried? What EXACTLY is it you want to achieve?
local Click = script.Parent
local GamePassID = 000000 -- Change this to your Gamepass ID.
Click.MouseClick:connect(function(player)
game:GetService("MarketplaceService"):PromptPurchase(player,GamePassID)
end)
Script should be a child of the click detector.
You will need to put a click detector inside the model/part that you want the player to click & then make a script inside the Model or ServerScriptService, but to keep it clean, you can make it in the model.
Then you could script it up something like this:
local Detector = script.Parent:FindFirstChildOfClass("ClickDetector")
local gamepassID = 21414124 --Your Gamepass ID
local MarketplaceService = game:GetService("MarketplaceService")
Detector.MouseClick:connect(function(player) --MouseClick event automatically passes the player who clicked it.
MarketplaceService:PromptGamePassPurchase(player, gamepassID ) -- You then prompt the gamepass purchase prompt to that person who clicked it.
end)

You are not to ask for scripts in devforum.
I suggest you look up click detectors for this
