Hello, I have written some code to better improve Roblox’s Jumping Mechanics by disabling auto jumping completely and also adding a slight delay before you can jump again.
The problem with the previous tutorials on this same function is that they are now outdated and no longer working as intended or not at all. Another problem is that they were not designed for modern Lua structure or incorrect use of functions.
Let’s start off with defining our Services.
--[[ SERVICES ]]
local UserInputService = game:GetService("UserInputService")
local RunService = game:GetService("RunService")
local Players = game:GetService("Players")
Now that our services have been defined let’s move on to defining our Character and Humanoid which we will use later on.
--[[ CHARACTER ]]
local Character = Players.LocalPlayer.Character or Players.LocalPlayer.CharacterAdded:wait()
local Humanoid = Character:WaitForChild("Humanoid")
The method I use to define the Character variable is quite simple and less likely to break the script if it runs before the character has a chance to be added. Now we have to define our more dynamic variables.
--[[ VARIABLES ]]
local CanJump = true
local LastJumpTime = 0
CanJump will determine if we can jump later on, now we have to write the functions in order for this script to work as intended.
--[[ JUMPING ]]
UserInputService.JumpRequest:Connect(function()
if CanJump then
Humanoid:SetStateEnabled(Enum.HumanoidStateType.Jumping, true)
LastJumpTime = tick()
CanJump = false
else
Humanoid:SetStateEnabled(Enum.HumanoidStateType.Jumping, false)
end
end)
This is not enough, so we will add a loop that will continuously check we if can jump or else we will only be able to jump once since we’re not actually changing the CanJump variable.
--[[ CHECKING IF YOU CAN JUMP ]]
RunService.Heartbeat:Connect(function()
if not CanJump and tick() >= LastJumpTime + 1 and not game:GetService("UserInputService"):IsKeyDown(Enum.KeyCode.Space) then
CanJump = true
end
end)
Using heartbeat is more reliable since instead of firing every time a new frame is rendered it fires every time the “tick” changes ( Roughly 60 times per second ). If you want to change the Jump Delay you will need to change “1” from tick() >= LastJumpTime + 1 to any number ( In seconds ).

Make sure to place this code inside of a [ LocalScript ] in [ StarterPlayer > StarterPlayerScripts ]
