Hi there, if you guys have used CT_mod or Insomniax, youve probably seen the class box on top of the target frame showing the class of your target.

Im trying to make a simple addon that would make a similar box that is draggable which i can use with whatever mod i want. A standalone you might say.

I tried ripping code from the old money_display and CT_unitframes and came up with this.

The xml file:

<Ui xsi:schemaLocation="http://www.blizzard.com/wow/ui/">
<Script file="Myown.lua"/>
<Frame name="MyownFrame" frameStrata="BACKGROUND" toplevel="true" enableMouse="false" movable="true" parent="UIParent">
<Size>
<AbsDimension x="125" y="25"/>
</Size>
<Backdrop name="MyownBackdrop" bgFile="Interface\TutorialFrame\TutorialFrameBackground" edgeFile="Interface\Tooltips\UI-Tooltip-Border" tile="true">
<EdgeSize>
<AbsValue val="16"/>
</EdgeSize>
<TileSize>
<AbsValue val="16"/>
</TileSize>
<BackgroundInsets>
<AbsInset left="3" right="5" top="3" bottom="5"/>
</BackgroundInsets>
</Backdrop>
<Layers>
<Layer level="ARTWORK">
<FontString name="MyownText" hidden="false" inherits="GameFontNormal" text="">
<Anchors>
<Anchor point="CENTER"/>
</Anchors>
</FontString>
</Layer>
</Layers>
<Scripts>
<OnLoad>
this:SetBackdropColor(0, 0, 1, 0.5);
this:RegisterEvent("UNIT_FACTION");
this:RegisterEvent("UNIT_DYNAMIC_FLAGS");
this:RegisterEvent("PLAYER_TARGET_CHANGED");
this:RegisterEvent("PARTY_MEMBERS_CHANGED");
</OnLoad>
<OnEvent>
Myown_SetTargetClass();
if event == "VARIABLES_LOADED" then
MO_LoadVariables();
end
</OnEvent>
<OnMouseDown>
if ( arg1 == "LeftButton" ) then
MyownFrame:StartMoving();
end
</OnMouseDown>
<OnMouseUp>
if ( arg1 == "LeftButton" ) then
MyownFrame:StopMovingOrSizing();
MO_SavePosition();
end
</OnMouseUp>

</Scripts>
</Frame>
</Frame>
</Ui>


The Lua file:
function Myown_SetTargetClass()
if ( not UnitExists("target") ) then return; end
local r, g, b;
r = 0; g = 0; b = 1;
if ( UnitPlayerControlled("target") ) then
if ( UnitCanAttack("target", "player") ) then
-- Hostile players are red
if ( not UnitCanAttack("player", "target") ) then
r = 0.0;
g = 0.0;
b = 1.0;
else
r = UnitReactionColor[2].r;
g = UnitReactionColor[2].g;
b = UnitReactionColor[2].b;
end
elseif ( UnitCanAttack("player", "target") ) then
-- Players we can attack but which are not hostile are yellow
r = UnitReactionColor[4].r;
g = UnitReactionColor[4].g;
b = UnitReactionColor[4].b;
elseif ( UnitIsPVP("target") ) then
-- Players we can assist but are PvP flagged are green
r = UnitReactionColor[6].r;
g = UnitReactionColor[6].g;
b = UnitReactionColor[6].b;
else
-- All other players are blue (the usual state on the "blue" server)
r = 0.0;
g = 0.0;
b = 1.0;
end
else
local reaction = UnitReaction("target", "player");
if ( reaction ) then
r = UnitReactionColor[reaction].r;
g = UnitReactionColor[reaction].g;
b = UnitReactionColor[reaction].b;
else
r = 0; g = 0; b = 1;
end
end

if ( r == 1 and g == 0 and b == 0 ) then
MyownFrame:SetBackdropColor(1, 0, 0, 1);
else
MyownFrame:SetBackdropColor(r, g, b, 0.5);
end
if ( UnitClass("target") ) then
MyownText:SetText(UnitClass("target"));
end
end


function MO_LoadVariables()
if not MO_Save then
MO_Save = { };
MO_Save.x = GetScreenWidth()/2;
MO_Save.y = 50;
end

getglobal("MyownFrame"):ClearAllPoints();
getglobal("MyownFrame"):SetPoint("BOTTOMLEFT", "UIParent", "BOTTOMLEFT", MD_Save.x, MD_Save.y);
end

function MO_SavePosition()
MO_Save.x = getglobal("MyownFrame"):GetLeft();
MO_Save.y = getglobal("MyownFrame"):GetBottom();
end



The toc file:
## Interface: 4150
## Title: Myown
## Notes: Display class
## OptionalDeps:
## Dependencies:
## SavedVariables: MO_Save
Myown.xml


I tried that but nothing appeared. Not even a small box. My initial comments would be that i removed an anchor from the main frame, is this a bad thing? Secondly, the top line of my XML may be truncated coz the usual thing i see is


<Ui xmlns="http://www.blizzard.com/wow/ui/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.blizzard.com/wow/ui/
C:\Projects\WoW\Bin\Interface\FrameXML\UI.xsd">

Is that also a cause of problems?

Like i said, i cant even see a box which i thought the initial frame in my XML would create (MyownFrame)

Thanks.
