Hi,

thanks so much for your answer.

I have tried your code and it doesn't give any errors when the player enters world ...and the bars are at 0.8 ...

5:  hooksecurefunc(MultiBarRight, "SetScale", function(self, scale)
6:     if scale ~= 0.8 then self:SetScale(0.8) end
7:  end)
 
9:  hooksecurefunc(MultiBarLeft, "SetScale", function(self, scale)
10: if scale ~= 0.8 then self:SetScale(0.8) end
11:end)

But when I finish the quest BeachHead (which is vehicle exit) I got:

1x [ADDON_ACTION_BLOCKED] AddOn 'gmActionBars' tried to call the protected function 'UNKNOWN()'.
!BugGrabber\BugGrabber.lua:519: in function <!BugGrabber\BugGrabber.lua:519>

FrameXML\ActionBarController.lua:62: in function <FrameXML\ActionBarController.lua:51>
 
Locals:
InCombatSkipped

And the MultiBarRight is to 1.0 scale again (I don't use the MultiBarLeft)

The FrameXML\MultiActionBars.lua:85

local scale = 1;
if ( contentHeight > availableSpace ) then
    scale = availableSpace / contentHeight;
end
        MultiBarRight:SetScale(scale);    --> line 85
if ( showLeft ) then
        MultiBarLeft:SetScale(scale);
end

I really don't understand why is not possible in an easy way to set scale to a value different from 1

P.s.
The other thing I don't understand is why if I call this code instead:

hooksecurefunc(MultiBarRight, "SetScale", function(self, scale)
     self:SetScale(0.8)
end)

which basically do the same thing of the code above it fired a lot of errors like:
