oh no i didnt read it
(dis is for word limit)

cureog · October 4, 2021, 8:24am

u must do da “load animtion” part inside a function
or else it will run loadanimtion on a nil humanoid
(or u need to put da function characterAdded(newCharacter) and things invole above da humanoid:LoadAnimation() part)

You’re actually wrong, read the error output.

ZacharyZaxorDDD · October 5, 2021, 1:08am

You should be providing an Animation Instance inside the script.

That’s because this variable local animator = humanoid:FindFirstChildOfClass("Animator") was outside the function that’s why it’s giving you an index nil error. Try using this script, you must provide an Animation Instance with the asset id inside of it. The Animation Instance is parented to the LocalScript.

you should load the animation on the animator not the humanoid.

So many functions that you don’t even need to make. nvm im just wrong, heres an edited script.

This part keeps getting an error.

PedroGame007Pg · October 5, 2021, 5:01pm

Try to use :WaitForChild(“Animation”)

Luxurious_Scripter · October 5, 2021, 5:05pm

My script does not have an animation in it though.

PedroGame007Pg · October 5, 2021, 5:06pm

So create it, and set the AnimationId

Luxurious_Scripter · October 5, 2021, 5:11pm

This is what I got but line 8 is an error.

PedroGame007Pg · October 5, 2021, 5:11pm

You need to set AnimationId before to load it, into Animator.

Luxurious_Scripter · October 5, 2021, 5:13pm

So do I need to put the AnimID line under the AnimationInstance line?

PedroGame007Pg · October 5, 2021, 5:14pm

Yes, after create it set animation id, then load it into animator.

Luxurious_Scripter · October 5, 2021, 5:17pm

So like this?

local UserInputService = game:GetService("UserInputService")
local localPlayer = game.Players.LocalPlayer
local character = localPlayer.Character or localPlayer.CharacterAdded:Wait()
local humanoid = character:WaitForChild("Humanoid")
local animator = humanoid:FindFirstChildOfClass("Animator")
local Animation = Instance.new("Animation")
Animation.AnimationId = "rbxassetid://7637267231"
local animationTrack = animator:LoadAnimation(Animation)

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
		animationTrack:Play()
		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)

PedroGame007Pg · October 5, 2021, 5:19pm

Yes.

(Ignore this is just for roblox let me post it)
