Hey, so I found this script online, it basically does like a little shine animation to when you press a key on your actionbar.

It won't work on prepatch idk why, can someone help me fix it and if you managed to fix it put the full code as a reply please? Thanks alot !!

local animationsCount, animations = 5, {}
local animationNum = 1
local frame, texture, alpha1, scale1, scale2, rotation2 
for i = 1, animationsCount do
    frame = CreateFrame("Frame")
    texture = frame:CreateTexture() texture:SetTexture('Interface\\Cooldown\\star4') texture:SetAlpha(0) texture:SetAllPoints() texture:SetBlendMode("ADD")
    animationGroup = texture:CreateAnimationGroup()
    alpha1 = animationGroup:CreateAnimation("Alpha") alpha1:SetChange(1) alpha1:SetDuration(0) alpha1:SetOrder(1)
    scale1 = animationGroup:CreateAnimation("Scale") scale1:SetScale(1.5, 1.5) scale1:SetDuration(0) scale1:SetOrder(1)
    scale2 = animationGroup:CreateAnimation("Scale") scale2:SetScale(0, 0) scale2:SetDuration(0.3) scale2:SetOrder(2)
    rotation2 = animationGroup:CreateAnimation("Rotation") rotation2:SetDegrees(90) rotation2:SetDuration(0.3) rotation2:SetOrder(2)
    animations[i] = {frame = frame, animationGroup = animationGroup}
end 
local AnimateButton = function(self)
    if not self:IsVisible() then return true end
    local animation = animations[animationNum]
    local frame = animation.frame
    local animationGroup = animation.animationGroup
    frame:SetFrameStrata(self:GetFrameStrata())
    frame:SetFrameLevel(self:GetFrameLevel() + 10)
    frame:SetAllPoints(self)
    animationGroup:Stop()
    animationGroup:Play()
    animationNum = (animationNum % animationsCount) + 1
    return true
end 
hooksecurefunc('MultiActionButtonDown', function(bname, id) AnimateButton(_G[bname..'Button'..id]) end) 
hooksecurefunc('ActionButtonDown', function(id)
     local button
     if C_PetBattles.IsInBattle() then
          if PetBattleFrame then
               if id > NUM_BATTLE_PET_HOTKEYS then return end
               button = PetBattleFrame.BottomFrame.abilityButtons[id]
               if id == BATTLE_PET_ABILITY_SWITCH then
                    button = PetBattleFrame.BottomFrame.SwitchPetButton;
               elseif id == BATTLE_PET_ABILITY_CATCH then
                    button = PetBattleFrame.BottomFrame.CatchButton;
               end
               if not button then return end
          end
          return
     end 
     if OverrideActionBar and OverrideActionBar:IsShown() then
          if id > NUM_OVERRIDE_BUTTONS then return end
          button = _G["OverrideActionBarButton"..id]
     else
          button = _G["ActionButton"..id]
     end
     if not button then return end 
     AnimateButton(button)
end)

I don't know enough to spot all the potential problems but SetChange() was removed and replaced with SetToAlpha() and SetFromAlpha().
