  1. What do you want to achieve?

I want to achieve a double jump system the works

  1. What is the issue?

The issue is sometimes when I am double jumping the ui that shows how many double jumps I have left disables and then if I double jump again it restarts the double jumps so it makes me jump more!

  1. What solutions have you tried so far?

Finding a solution!

local userInput = game:GetService("UserInputService")

local player = game.Players.LocalPlayer

repeat wait() until player.Character

local char = player.Character
player.CharacterAdded:Connect(function(c)
	char = c
end)

local jumpEvent = script.Parent.Jumped
local animation = script:WaitForChild("Boost")
local anim = char.Humanoid:LoadAnimation(animation)
local upgradeEvent = script.Parent.Upgrade

local background = script.Parent.Background
local bar = background.Bar
local label = script.Parent.Label

local maxJumps = player.DJumps.MaxDJumps.Value
local jumpsLeft = maxJumps

local onGround = false
local debounce = false

coroutine.resume(coroutine.create(function()
	while wait(.1) do
		local ray = Ray.new(char.HumanoidRootPart.Position, Vector3.new(0,-3,0))
		local hit,pos = workspace:FindPartOnRayWithIgnoreList(ray,{char})

		if hit then
			onGround = true

			bar:TweenSize(UDim2.new(1,0,1,0),
				Enum.EasingDirection.InOut,
				Enum.EasingStyle.Quad,
				.1
			)

			maxJumps = player.DJumps.MaxDJumps.Value
			char.Humanoid.JumpPower = 50
			script.Parent.Enabled = false
			bar.Visible = true
			jumpsLeft = maxJumps
			label.Text = jumpsLeft.." / "..maxJumps
		else
			Vector3.new(0,-4,0)
			wait(0.1)
			onGround = false
		end
	end
end))

upgradeEvent.Event:Connect(function(newValue)
	maxJumps = newValue
end)

jumpEvent.Event:Connect(function()
	if onGround == false then
		script.Parent.Enabled = true
	end

	if jumpsLeft > 0 and char and debounce == false then
		if onGround == false then
			debounce = true
			jumpsLeft -= 1
			label.Text = jumpsLeft.."/"..maxJumps
			char.Humanoid.JumpPower = 50

			bar:TweenSize(UDim2.new(jumpsLeft / maxJumps,0,1,0),
				Enum.EasingDirection.InOut,
				Enum.EasingStyle.Quad,
				.1
			)
			if jumpsLeft == 0 then
				delay(.1, function()
					bar.Visible = false
				end)
			end
			char.Humanoid.JumpPower = 125
			anim:Play()
			char.Humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
			delay(0.3, function()
				debounce = false
			end)
		end
	end
end)

userInput.JumpRequest:Connect(function()
	jumpEvent:Fire()
end)

Thank you in advance!

Uhh, so innificient try this:

local double = false
game:GetService("UserInputService").JumpRequest:Connect(function()
if double == false and game.Players.LocalPlayer.Character.Humanoid:GetState() == Enum.HumanoidStateType.FreeFall then
double = true
game.Players.LocalPlayer.Character.Humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
end
end)

game.Players.LocalPlayer.Character.Humanoid.StateChanged:Connect(function()
if game.Players.LocalPlayer.Character.Humanoid:GetState() == Enum.HumanoidStateType.Landed then
end)
#3

Where am I supposed to add this to the script?

#4

To the localscript (please don’t put it yet, I’m working on it)

#5

Oh ok, thank you so much though!

#6

Ok here it is,

local UserInputService = game:GetService("UserInputService")
local localPlayer = game.Players.LocalPlayer
local character
local humanoid
local JMP = 80 -- jumppower of doiblejump
local originalJMP = 50 -- the normal jumppower
 
local canDoubleJump = false
local hasDoubleJumped = false
 
function onJumpRequest()
	if not character or not humanoid or not character:IsDescendantOf(workspace) or
	 humanoid:GetState() == Enum.HumanoidStateType.Dead then
		return
	end
	
	if canDoubleJump and not hasDoubleJumped then
		hasDoubleJumped = true
humanoid.JumpPower = JMP

humanoid:ChangeState(Enum.HumanoidStateType.Jumping)

humanoid.StateChanged:Wait()
humanoid.JumpPower = originalJMP
	end
end
 
local function characterAdded(newCharacter)
	character = newCharacter
	humanoid = newCharacter:WaitForChild("Humanoid")
	
	humanoid.StateChanged:connect(function(old, new)
		if new == Enum.HumanoidStateType.Freefall then
			canDoubleJump = true
		end
	end)
end
 
if localPlayer.Character then
	characterAdded(localPlayer.Character)
end
 
localPlayer.CharacterAdded:connect(characterAdded)
UserInputService.JumpRequest:connect(onJumpRequest)

I copied it from the tutorial lol, was too lazy

Put the localscript in StarterPlayer - starterplayerscripts

#7

The thing is I have like a different way of that script because in my game you can buy more jumps so if a player buys some more jumps then the value of the jumps goes up!

#8

change the jumppower then when the player double jumps then set it to normal when it landed.

#9

I’ve edited the code so that you can do that, you have the original JMP of player and the upgraded jumppower of doublejump, the making of the “upgrading jumppower double jump” is you need to script.

#10

This still doesn’t solve my issue

#11

The devhub has a great section on exactly this.

local UserInputService = game:GetService("UserInputService")
local localPlayer = game.Players.LocalPlayer
local character
local humanoid
 
local canDoubleJump = false
local hasDoubleJumped = false
local oldPower
local TIME_BETWEEN_JUMPS = 0.2
local DOUBLE_JUMP_POWER_MULTIPLIER = 2
 
function onJumpRequest()
	if not character or not humanoid or not character:IsDescendantOf(workspace) or
	 humanoid:GetState() == Enum.HumanoidStateType.Dead then
		return
	end
	
	if canDoubleJump and not hasDoubleJumped then
		hasDoubleJumped = true
		humanoid.JumpPower = oldPower * DOUBLE_JUMP_POWER_MULTIPLIER
		humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
	end
end
 
local function characterAdded(newCharacter)
	character = newCharacter
	humanoid = newCharacter:WaitForChild("Humanoid")
	hasDoubleJumped = false
	canDoubleJump = false
	oldPower = humanoid.JumpPower
	
	humanoid.StateChanged:connect(function(old, new)
		if new == Enum.HumanoidStateType.Landed then
			canDoubleJump = false
			hasDoubleJumped = false
			humanoid.JumpPower = oldPower
		elseif new == Enum.HumanoidStateType.Freefall then
			wait(TIME_BETWEEN_JUMPS)
			canDoubleJump = true
		end
	end)
end
 
if localPlayer.Character then
	characterAdded(localPlayer.Character)
end
 
localPlayer.CharacterAdded:connect(characterAdded)
UserInputService.JumpRequest:connect(onJumpRequest)
