How do I edit the text in a TextBox from a variable?
I'm trying to make a gun for my roblox game, and I want a GUI to give info to the player, like how much ammo is left in a clip, whether or not you're reloading etc. I am trying to get the variable "Ammo" 's value (12) into the text for the textbox, and have it decrease by 1 when it's fired. My code is:
local canFire = true
local Ammo = 12
local maxAmmo = 12
local ammoCounterText = game.StarterGui.ScreenGui.Frame.AmmoCounter.Text
script.Parent.Equipped:Connect(function(mouse)
mouse.Button1Down:Connect(function()
if canFire then
game.ReplicatedStorage.RayCastEvent:FireServer(script.Parent.ForBullets.Position, mouse.Hit.Position)
Ammo = Ammo - 1
ammoCounterText = Ammo
canFire = false
wait(0.5)
canFire = true
end
end
)
if Ammo < 1 then
canFire = false
wait(5)
Ammo = 12
canFire = true
end
end)

local ammoCounterText = game.StarterGui.ScreenGui.Frame.AmmoCounter.Text
Here, the variable is not being set to the AmmoCounter UI element, it's being set to what its text is as soon as the script starts running. Just remove the .Text on the end.
local ammoCounterText = game.StarterGui.ScreenGui.Frame.AmmoCounter
In order to modify its text, just do this:
ammoCounterText.Text = "Ammo: " .. Ammo
Also, I wouldn't keep track of how much ammo the gun is supposed to have on the client, as exploiters could easily just fire the gun an infinite amount of times. I'd create an IntValue and use it to keep track of the ammo. The server will do the subtraction. Check on the client and on the server before actually firing the gun.
