UF Based on Class

[netquick]

Hello community.

I was playing around with rdx since a while and I have set up my own unitframes now.
As a druid I created a special player-unitframe that shows my druid's mana even in cat- and bearform.
The "problem" is now, that I have two player unitframes - one for druids and one for other classes. I am looking for a way to switch the playerframe based on the class i play.
I know i could do it with desktops, but I prefer to have a single desktop that works for all classes. I like to keep the list of desktops to choose as small as possible.

I don't know if there is a way to script it in autoexec. I am very bad in lua at the moment.

I would be very thankful for hints and suggestions about that. I can imagine that there are different ways to realize that.

greetings, netquick

I played around a bit with the frames and still have no final solution. Currently I use different desktops with different playerframes.

What I did so far:

I added the following code to my autoexec script:

RDX.RegisterFeature({
    name = "Variable: Druid Mana (dmana)";
    title = "Variable: Druid Mana (dmana)";
    category = i18n("Variables: Unit Status");
    IsPossible = function(state)
        if not state:Slot("EmitPaintPreamble") then return nil; end
        if state:Slot("Var_dmana") then return nil; end
        return true;
    end;
    ExposeFeature = function(desc, state, errs)
        state:AddSlot("Var_dmana");
        state:AddSlot("FracVar_dmana");
        return true;
    end;
    ApplyFeature = function(desc, state)
        state:Attach(state:Slot("EmitPaintPreamble"), true, function(code) code:AppendCode([[
local maxmana = UnitPowerMax("player",0);
local actmana = UnitPower("player",0);     
dmana = format("%.2f", (actmana/maxmana));
]]); 
        end);
        local mux = state:GetContainingWindowState():GetSlotValue("Multiplexer");
        local mask = mux:GetPaintMask("POWER");
        mux:Event_UnitMask("UNIT_POWER", mask);
    end;

    UIFromDescriptor = VFL.Nil;
    CreateDescriptor = function() return { feature = "Variable: Druid Mana (dmana)" }; end
});

I created an additional bar that shows this variable "dmana" under the regular powerbar. It works fine on my druid. I always have control over my manapool.

When I play another class that uses mana it works too. There is just a little difference in updating the two bars (powerbar and dmana-bar)

But when I play a class without mana it throws an error. That's why I asked about a way to switch unitframes.
Now I thought about scripting it the way that "dmana" only shows mana if unit player is a mana class and energy, rage or runic power if it's that kind of power.

Something like:

local maxmana = UnitPowerMax("player",0);
local actmana = UnitPower("player",0);
local maxpwr = UnitPowerMax("player");
local actpwr = UnitPower("player")     
local isclass = UnitClass("player")

if isclass = druid then
	dmana = format("%.2f", (actmana/maxmana));
else
	dmana = format("%.2f", (actpwr/maxpwr));
end;

I am that bad in lua & scripting that I don't know how to correctly code that if/else part. Any help about that?

Thanks i.a.

1. Create a Symlink-Type Object and set the link to one of your Unitframes
2. Point your Single-Unitframe Window to that Symlink instead of the actual Unitframe
3. Add something like this to your autoexec script:

if (UnitClass("PLAYER") == "Druid") then
   RDXDB.SetSymLinkTarget("path:to_your_simlink", "path:to_your_druid_unitframe")
else
   RDXDB.SetSymLinkTarget("path:to_your_simlink", "path:to_your_NONdruid_unitframe")
end

Add SVN

ApplyFeature = function(desc, state)
		state:Attach(state:Slot("EmitPaintPreamble"), true, function(code) code:AppendCode([[
			local dmana = 0;
			if UnitClass(uid) == "DRUID" then
				dmana = format("%.2f", (UnitPower(uid,0)/UnitPowerMax(uid,0)));
			end
			]]);
		end);
		local mux = state:GetContainingWindowState():GetSlotValue("Multiplexer");
		local mask = mux:GetPaintMask("POWER");
		mux:Event_UnitMask("UNIT_POWER", mask);
	end;

Thanks a lot!
for:
answering my question about changing the frame with symlinks

for:
adding the code to svn
one thought about it:

instead of returning "0" when player is not a druid, can you change it to show actual power then? Reason: I create a powerbar with let's say 10px and a dmana-bar with 4px. If player is not a druid I would make it look like a 14px powerbar when both bars show the actual powertype. It's the same like it looks on my druid when in no form.

ApplyFeature = function(desc, state)
		state:Attach(state:Slot("EmitPaintPreamble"), true, function(code) code:AppendCode([[
			local dmana = 0;
			if UnitClass(uid) == "DRUID" then
				dmana = format("%.2f", (UnitPower(uid,0)/UnitPowerMax(uid,0)));
			else
				dmana = format("%.2f", (UnitPower(uid)/UnitPowerMax(uid)));
			end
			]]);
		end);
		local mux = state:GetContainingWindowState():GetSlotValue("Multiplexer");
		local mask = mux:GetPaintMask("POWER");
		mux:Event_UnitMask("UNIT_POWER", mask);
	end;

What do you think? The only problem I had with two bars showing the same powertype: there was a little difference in updating the bars, but I think it was more because of my bad skills than a real issue.

Again many thanks for your help with that - I really love your addon.
