Sliding Panel

[Waky]

Remade the code here:

OnLoad:

local open = false;
local active = false;
local xOffset = 100;
local yOffset = 0;
local animDuration = 2;
local point, relTo, relPt, xOff, yOff;

self.animGroup = self:CreateAnimationGroup("SlidingFrame");
self.animOpen = self.animGroup:CreateAnimation("Translation");
self.animOpen:SetDuration(animDuration);
self.animOpen:SetOrder(1);
self.animOpen:SetOffset(-xOffset,yOffset);
self.animOpen:SetScript("OnFinished",function()
  self.animGroup:Pause();
  active = false;
end)
self.animClose = self.animGroup:CreateAnimation("Translation");
self.animClose:SetDuration(animDuration);
self.animClose:SetOrder(2);
self.animClose:SetOffset(xOffset,yOffset);
self.animClose:SetScript("OnFinished",function() active = false; end)
self:SetScript("OnMouseDown",function(self)
if active==false then 
  if open==false then
    active = true;
    open = true;
    self.animGroup:Play();
  else
    active = true;
    open = false;
    self.animGroup:Play();
  end
end
end)

This manner prevents the frame from having to be positioned at all, and can tell if it's currently opening/closing to prevent errors.

Hope this works!
