Creating a Double Jump Script in Roblox: A Step-by-Step Guide

Creating a Double Jump Script in Roblox: A Step-by-Step Guide

In Roblox, you can create a double jump script to add an extra layer of fun and excitement to your game. This guide will walk you through the process of creating a double jump script from scratch, using Roblox Studio and the Lua scripting language.

Step 1: Open Roblox Studio

  1. Launch Roblox Studio.
  2. Click “Create New Place” or open an existing project.

Step 2: Create a Local Script

  1. In the Explorer window, locate the “StarterPlayer” object.
  2. Right-click on “StarterPlayerScripts” and choose “Insert Object.”
  3. Select “LocalScript” from the list and name it “DoubleJump.”

Step 3: Initialize Variables

In the newly created “DoubleJump” script, we’ll start by initializing some variables. Add the following code to your script:

local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")
local canDoubleJump = false
local hasDoubleJumped = false
local jumpCount = 0

Step 4: Create Functions

Now, let’s create the necessary functions for the double jump script. Add the following code below the variables you initialized in the previous step:

local function onJumpRequest()
    if jumpCount < 2 then
        jumpCount = jumpCount + 1
        humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
    end
end

local function onLanded()
    jumpCount = 0
end

Step 5: Connect Functions to Events

Next, we need to connect our functions to the appropriate events. Add the following lines of code below the functions you created in the previous step:

humanoid.JumpRequest:Connect(onJumpRequest)
humanoid.Landed:Connect(onLanded)

Step 6: Test Your Double Jump Script

  1. Click the “Play” button in Roblox Studio to test your double jump script.
  2. Once the game starts, try pressing the jump key (spacebar) twice to perform a double jump.

The complete “DoubleJump” script should look like this:

local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")
local canDoubleJump = false
local hasDoubleJumped = false
local jumpCount = 0

local function onJumpRequest()
    if jumpCount < 2 then
        jumpCount = jumpCount + 1
        humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
    end
end

local function onLanded()
    jumpCount = 0
end

humanoid.JumpRequest:Connect(onJumpRequest)
humanoid.Landed:Connect(onLanded)

Now you have successfully created a double jump script in Roblox! This script can be easily modified or expanded upon to create even more advanced mechanics for your game. Enjoy experimenting and enhancing your Roblox creations with this new feature!
