Does Anyone know how to script a Paintball Sentry with projectiles and raycasting with hopperbins?

local hopperbin = script.Parent
local camera = workspace.CurrentCamera
local player = game.Players.LocalPlayer
local character = player.Character
local bullets = workspace.Bullets
local reloadTime = .1
local spread = 1
local recoil = 1
local fire = false
local firing = false
local bulletSpeed = 250
local bulletDrop = 0
local bursts = 25
local distance = 125




_G.shooterSelected = (function(mouse)
	mouse.Icon = "http://www.roblox.com/asset/?id=15324984" 
**
*--This is copied from Automatic hopperbin local script--***
	
mouse.Button1Down:connect(function()
		clicked(mouse)
	end)
	mouse.Button1Up:connect(unClicked)
	mouse.KeyDown:connect(_G.animateKeyPressed)
end)

function clicked(mouse)
	local gun = camera.Gun
	if (character.Humanoid.Health > 0) then
		if (not fire) then
			fire = true
			firing = true
			while (firing) do
				local head = character.Head
				local startPos = (gun.CFrame * CFrame.new(0, -2, 0)).p
				local endPos = (camera.CoordinateFrame * CFrame.new(0, 0, -100)).p
				local distance = (endPos - startPos).magnitude
				local random = Vector3.new((math.random(-spread, spread) / 250) * distance, (math.random(-spread, spread) / 250) * distance, (math.random(-spread, spread) / 250) * distance)
				local shot = gun.Fire
				if (not _G.sighted) then
					_G.fireBullet("Automatic", startPos, endPos + random, 100, bulletSpeed, bulletDrop, player.TeamColor, bullets)
				else
					_G.fireBullet("Automatic", startPos, endPos, 100, bulletSpeed, bulletDrop, player.TeamColor, bullets)
				end
				recoilCam()
				shot:play()
				wait(0.1)
			end
			delay(reloadTime, (function() fire = false end))
		end
	end
end

function unClicked()
	firing = false
end

function recoilCam()
	coroutine.resume(coroutine.create(function()
		camera.Focus = camera.Focus + Vector3.new(0, recoil / 100, 0)
		local interval = 20
		for i = 1, interval do
			wait(0.01)
			camera.Focus = camera.Focus - Vector3.new(0, (recoil / 100) / interval, 0)
		end
	end))
end
