Tool won't stop playing animation upon unequipping?

Hi, so a better way to go about this and might as well solve your problem is by adding a variable that tracks the current animation. Then when it is time to stop the animations you will specifically call :Stop() on the animation that is currently playing.

Like so:

local Tool = script.Parent
local fire = Tool.Fire
local draw = Tool.Draw
local idle = Tool.Idle

	local currentAnim -- Here is where we add the variable

local AnimateValue = script.Parent.AnimateValue

Tool.Equipped:connect(function()
    AnimateValue.Value = true
    local Character = Tool.Parent
    local Humanoid = Character.Humanoid

    local AnimationTrack = Humanoid:LoadAnimation(draw)
    local AnimationTrack1 = Humanoid:LoadAnimation(idle)
    if AnimateValue.Value == true then
	currentAnim = AnimationTrack -- set the current animation
        AnimationTrack:Play()
        wait(.5)
	currentAnim:Stop() -- stop the previous animation for new one
	currentAnim = AnimationTrack1 -- set the current animation
        AnimationTrack1:Play()
    else
        if AnimationTrack1.IsPlaying then
            AnimationTrack1:Stop()
        end
    end

end)


Tool.Unequipped:connect(function()
	AnimateValue.Value = false
	currentAnim:Stop() -- stop the current animation on unequip
end)



Tool.Activated:Connect(function()
    local Character = Tool.Parent
    local Humanoid = Character.Humanoid

    local AnimationTrack = Humanoid:LoadAnimation(fire)
    AnimationTrack:Play()
end)
