heyyyy i am trying to make a jump stamina feature script is parented under a frame in a screen gui in the starter gui
local players = game:GetService("Players")
local player = players.LocalPlayer
local UIS = game:GetService("UserInputService")
local jumps_left_value = script.Parent.jumps_left.Value
--local transparency_module = script.Parent.transparency_script
local size_script = script.Parent.size_script
function jump_pressed()
jumps_left_value = jumps_left_value - 1
print(jumps_left_value .. " jump(s) left")
end
if UIS:IsKeyDown(Enum.KeyCode.Space) then
jump_pressed()
print("player jumped")
end
there is no error but i know i am not getting a player jumped in output

A few problems in your code:
Variables do not reference properties: The variable
jumps_left_valueonly stores the current value and changes made to the variable will not be reflected to the jumps_left IntValue/NumberValueThe if statement will only run once: Because the if statement is not wrapped in a loop / event that can fire many times, the if statement is only ran once and if the SpaceBar isn't held down, the if statement's scope will not be entered so the code inside will not be ran and it is never checked again
Conveniently, UserInputService provides an event called JumpRequest which fires when the client attempts to jump. Here, you can enable/disable jumps:
local jumps_left = script.Parent.jumps_left
local player = game.Players.LocalPlayer
local humaoid = player.Character:WaitForChild("Humanoid")
UIS.JumpRequest:Connect(function()
jumps_left.Value -= 1 -- "-=" is a compound assignment operator that is the same as "jumps_left.Value = jumps_left.Value - 1"
-- humanoid:SetStateEnabled(Enum.HumanoidStateType.Jumping, false/true) : this line can enable and disable jumping. Passing "true" will enable, passing "false" will disable
end)
