This is the code that I'm having issues with, I'm not sure if .IsPlaying doesn't work anymore or why damage isn't being done during the animation.

Here's a GIF of the problem https://gyazo.com/e9a04e1eeb147bdd6449182f25537d0d

hitbox.Touched:Connect(function(hit)
    local ehum = hit.Parent:FindFirstChild("Humanoid") or hit.Parent.Parent:FindFirstChild("Humanoid")
    if ehum and ehum ~= hum and ten and attackanim.IsPlaying == true then
        ten = false
        ehum:TakeDamage(20)
        wait(3)
        ten = true
        end
    end)
end
end

If I remove the "and attackanim.IsPlaying == true" the hit detection works but I only want the player to receive damage whilst the animation is playing.

Here's what it looks like https://gyazo.com/1994b33343b59006356b3a9144f32178
