So I want to make a tool that has different idle, jumping, walking and landing animations from the default. These animations also use every part of the Roblox model. When I unequip the tool all the animations return to normal except when I am jumping. When I unequip while jumping the falling animation will play continuously.

Any advice to fix this?

Here is my code. If you find any other problems please point them out. I am still relatively new to Roblox scripting in general.

Note: Some of the code in this script was is an attacking and throwing event. I only copied parts that had to do with the animations. hopefully I didn't miss anything. ????

--Animations--
local AnimIds = {
	tool.KnifeIdle, 
	tool.KnifeRun,
	tool.KnifeJump,
	tool.KnifeFreeFall
}

Character:WaitForChild("Humanoid")
local Animations = {
	KnifeIdleAnimation = Character.Humanoid:LoadAnimation(AnimIds[1]),
	KnifeRunAnimation = Character.Humanoid:LoadAnimation(AnimIds[2]),
	KnifeJumpAnimation = Character.Humanoid:LoadAnimation(AnimIds[3]),
	KnifeFreeFallAnimation = Character.Humanoid:LoadAnimation(AnimIds[4])
}

--AnimationEvents--

local function Initialrunning(speed)
	if IsEquiped.Value == false then return end
	if speed > 1 then
		NewAnim = Animations.KnifeRunAnimation
		NewAnim:Play()
	else
		NewAnim = Animations.KnifeIdleAnimation
		NewAnim:Play()
	end
end

local function Running(speed)
	if IsEquiped.Value == false then return end
	if speed > 0.75 then
		if Character.Humanoid:GetState() ~= Enum.HumanoidStateType.Jumping or Character.Humanoid:GetState() ~= Enum.HumanoidStateType.Freefall  then
			if NewAnim == Animations.KnifeRunAnimation then return end
			OldAnim = NewAnim
			NewAnim = Animations.KnifeRunAnimation
			OldAnim:Stop()
			NewAnim:Play()
		end
	elseif speed < 0.75 then
		if Character.Humanoid:GetState() ~= Enum.HumanoidStateType.Jumping or Character.Humanoid:GetState() ~= Enum.HumanoidStateType.Freefall then
			if NewAnim == Animations.KnifeIdleAnimation then return end
			OldAnim = NewAnim
			NewAnim = Animations.KnifeIdleAnimation
			OldAnim:Stop()
			NewAnim:Play()
		end
	end
end

local function Jumping(isActive)
	if IsEquiped.Value == false then return end
	OldAnim = NewAnim
	NewAnim = Animations.KnifeJumpAnimation
	OldAnim:Stop()
	NewAnim:Play()
	wait(.3)
	OldAnim = NewAnim
	NewAnim = Animations.KnifeFreeFallAnimation
	OldAnim:Stop()
	NewAnim:Play()
end

local function Standing(oldState, NewState)
	if IsEquiped.Value == false then return end
	if NewState == Enum.HumanoidStateType.None then
		print("Standing")
	end
end

local function Freefall(isActive)
	if IsEquiped.Value == false then return end
	if (JumpAnimTime.Value <= 0) then
		if NewAnim == Animations.KnifeFreeFallAnimation then return end
		OldAnim = NewAnim
		NewAnim = Animations.KnifeFreeFallAnimation
		OldAnim:Stop()
		NewAnim:Play()
	end
end

--OnEquip&UnequipEvents--
tool.Equipped:Connect(function()
	IsEquiped.Value = true
	
	Character:WaitForChild("Humanoid")
	local HumRootPart = Character:WaitForChild("HumanoidRootPart")
	
	local Speed = HumRootPart.Velocity -- returns a vector3 so
	print(Speed)
	
	local SpeedX = math.abs(Speed.X)
	local SpeedY = math.abs(Speed.Y)
	local SpeedZ = math.abs(Speed.Z)
	
	if SpeedX > 2 or SpeedZ > 2 and SpeedY < 0.2 then
		NewAnim = Animations.KnifeRunAnimation
		NewAnim:Play()
	elseif SpeedY > 0.5 then
		NewAnim = Animations.KnifeFreeFallAnimation
		NewAnim:Play()
	else
		NewAnim =  Animations.KnifeIdleAnimation
		NewAnim:Play()
	end
	
	CAT:BindAction("ThrowEvent", Throw, false, Enum.UserInputType.MouseButton1)
	CAT:BindAction("AttackMode", InteractionKeys, false, Enum.KeyCode.Q)
end)

tool.Unequipped:Connect(function()
	IsEquiped.Value = false
	
	for index, value in pairs(Animations) do
		value:Stop()
	end
	
	CAT:UnbindAction("ThrowEvent")
	CAT:UnbindAction("AttackMode")
end)
