Why won't my cannonball script make the cannon shoot?

I wanted to make my first minigame, but it doesn't seem to work. It's supposed to have cannons on one side shoot at the players on a bridge to knock them off, but it doesn't even shoot. This is what I'm using:

local Cannon = script.Parent
local CannonBody = Cannon.Union
local Cannonball = game.Workspace.Cannonball
local Wall = game.Workspace.Wall
local GameStart = false
local x = 13
local y = 5.312
local z = -62.5

if GameStart == true then
	local Clone = Cannonball:Clone()
	Clone.Position = Vector3.new(x, y, z)
	wait(1)
	Clone.Position = Vector3.new(x, y + 1, z + 1)
	if Wall.Touched == true then
		Clone:Destroy()
	end
end
wait(10)
GameStart = true

What can I do to fix this? Any help is appreciated!

Hayo! The issue you have is pretty simple to fix. You set the GameStart to false at the start, then test if it's true. It only happens once at the start of the script. You could have a function that calls it or do a while wait() do. Here's my run of it.

local Cannon = script.Parent
local CannonBody = Cannon.Union
local Cannonball = game.Workspace.Cannonball
local Wall = game.Workspace.Wall
local GameStart = false
local x = 13
local y = 5.312
local z = -62.5
 
function cannonFire()
 if GameStart == true then
    local Clone = Cannonball:Clone()
    Clone.Position = Vector3.new(x, y, z)
    wait(1)
    Clone.Position = Vector3.new(x, y + 1, z + 1)
    if Wall.Touched == true then
        Clone:Destroy()
    end
 end
end
wait(10)
GameStart = true
cannonFire()

You can remotely trigger the function using RemoteEvents [for FilteringEnabled] or bindableEvents.

I personally prefer RemoteEvents. You can learn about them here, http://wiki.roblox.com/index.php?title=Remote_Events_and_Functions

To properly implement a RemoteEvent, you can add,

script.RemoteEvent.OnServerEvent:Connect(cannonFire)

to the end of the script.

Hope I helped. :)
