Double jump not working

Script:

local player = game.Players.LocalPlayer
local uis = game:GetService("UserInputService")
local canjump = true
local havejumped = false
local humanoid = player.Character.Humanoid

humanoid.StateChanged:Connect(function(old,new)
    if new == Enum.HumanoidStateType.Landed then
        canjump = true
        havejumped = false
    elseif new == Enum.HumanoidStateType.Freefall then
        canjump = true
    else
        canjump = true
    end
end)

uis.JumpRequest:Connect(function()
    if canjump == true then
        if havejumped == false then
            humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
            havejumped = true
        end
    end
end)

Why are you not using the script provided in this article you linked? it basically got everything you need!

#3

I am trying to practice it, as I want to make a double boost plane, the script in the hub is for players, so I am practicing this to try later, tell why my script is not working pls

#4

I think because that!

local canjump = true ←

if new == Enum.HumanoidStateType.Landed then
canjump = true ←

You could make!

local canjump to false!

you made both true

why is the player able to double jump even if canjump is false

local player = game.Players.LocalPlayer
local uis = game:GetService("UserInputService")
local canjump = true
local humanoid = player.Character.Humanoid

humanoid.StateChanged:Connect(function(old,new)
    uis.JumpRequest:Connect(function()
        if new == Enum.HumanoidStateType.Freefall and canjump == true then
            canjump = false
            humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
        elseif new == Enum.HumanoidStateType.Landed then
            canjump = true
        end
    end)
end)

may not work. tried my best
May cause that!
don’t add canjump == true.
Example:
if new == Enum.HumanoidStateType.Freefall then
canjump = false

Try that.

local plr = game.Players.LocalPlayer
local uis = game:GetService("UserInputService")
local canjump = true

plr.Character.Humanoid.StateChanged:Connect(function(old,new)
  uis.JumpRequest:Connect(function()
  if new == Enum.HumanoidStateType.Freefall then
    canjump = false
        plr.Character.Humanoid:ChangeState(Enum.HumanoidStateType.Jumping)
             elseif new == Enum.HumanoidStateType.Landed then
               canjump = true
         end
    end)
end)

did not work he can infinitely go up

#8

Well tried my best!

Try to check Output.

or try changing that to! like you did.
if new == Enum.HumanoidStateType.Freefall and canjump == true then

#9 
 elseif new == Enum.HumanoidStateType.Landed and canjump == false then
            canjump = true
            print("bruh")
        end

its printing bruh even thought i did not land, thats a roblox studio bug isnt it?
