Need help shortening actionbar

[JamesR4494]

  
  --get the addon namespace
  local addon, ns = ...
  
  --get the config values
  local cfg = ns.cfg
  local barcfg = cfg.bars.bar5
  
  local bar = CreateFrame("Frame","rABS_MultiBarLeft",UIParent, "SecureHandlerStateTemplate")
  bar:SetHeight(barcfg.buttonsize*12+barcfg.buttonspacing*11)
  bar:SetWidth(barcfg.buttonsize)
  bar:SetPoint(barcfg.pos.a1,barcfg.pos.af,barcfg.pos.a2,barcfg.pos.x,barcfg.pos.y)
  bar:SetHitRectInsets(-cfg.barinset, -cfg.barinset, -cfg.barinset, -cfg.barinset)
  
  if barcfg.testmode then
    bar:SetBackdrop(cfg.backdrop)
    bar:SetBackdropColor(1,0.8,1,0.6)
  end
  bar:SetScale(barcfg.barscale)

  cfg.applyDragFunctionality(bar,barcfg.userplaced,barcfg.locked)

  MultiBarLeft:SetParent(bar)
  
  for i=1, 12 do
    local button = _G["MultiBarLeftButton"..i]
    button:ClearAllPoints()
    button:SetSize(barcfg.buttonsize, barcfg.buttonsize)
    if i == 1 then
      button:SetPoint("TOPLEFT", bar, 0,0)
    else
      local previous = _G["MultiBarLeftButton"..i-1]
      button:SetPoint("TOP", previous, "BOTTOM", 0, -barcfg.buttonspacing)
    end
  end
  
  if barcfg.showonmouseover then    
    local function lighton(alpha)
      if MultiBarLeft:IsShown() then
        for i=1, 12 do
          local pb = _G["MultiBarLeftButton"..i]
          pb:SetAlpha(alpha)
        end
      end
    end    
    bar:EnableMouse(true)
    bar:SetScript("OnEnter", function(self) lighton(1) end)
    bar:SetScript("OnLeave", function(self) lighton(0) end)  
    for i=1, 12 do
      local pb = _G["MultiBarLeftButton"..i]
      pb:SetAlpha(0)
      pb:HookScript("OnEnter", function(self) lighton(1) end)
      pb:HookScript("OnLeave", function(self) lighton(0) end)
    end    
  end

Trying to edit Roth UI's rActionBarStyler's bar 5 to make it so only 4 buttons show up instead of the default 12, is there anyway i could do this?

Find this:

button:SetPoint("TOP", previous, "BOTTOM", 0, -barcfg.buttonspacing)

Make it:

if i>4 then
  button:SetPoint("RIGHT",UIParent,9000,9000);
else
  button:SetPoint("TOP", previous, "BOTTOM", 0, -barcfg.buttonspacing)
end

That will move every button > 4 out of the window.

What would happen if you changed every instance of "for i=1, 12 do" to "for i=1, 4 do" in the code? Major errors?

Just curious here.

[zork]

The buttons are anchored on each other. If you do not reposition them they would keep their default anchors. (Even the Blizzard buttons are buttons are anchored that way)

[jeffy162]

Ahhhhh. So, you have to tell the buttons you don't want where to hide, in effect, instead of just telling them to not actually appear. Which is what I assumed (dangerous word, that) would happen if you changed that little bit of code.

Thank you for your explanation, Zork. As I've said before (somewhere), I'm not too good with Lua, but pretty handy with "copy-n-paste".

[JamesR4494]

Ah I see, thanks it worked.

How do I make this action bar horizontal like the bars on the bottom?

[Phanx]

Anchor them RIGHT to LEFT instead of TOP to BOTTOM.
