How to

Hi，guys. I want to set aura position. How can i make OUF AURA like this :

local AURA_START_X = 4;
local AURA_START_Y = 32;
local AURA_OFFSET_Y = 2;
local LARGE_AURA_SIZE = 50;		
local SMALL_AURA_SIZE = 23;		
local FIRST_AURA_ROW_WIDTH = 122;
local AURA_ROW_WIDTH =200;
local TOT_AURA_ROW_WIDTH = 101;
local NUM_TOT_AURA_ROWS = 2;		

local largeBuffList = {};
local largeDebuffList = {};
local auraRows = 0
local PLAYER_UNITS = {
	player = true,
	vehicle = true,
	pet = true,

You ask how, but what you want is someone to do it for you. People here will help you reach the goal, but they generally won't do all the work for you.

To answer how:
There's no easy solution to this. You would have to go over what the code currently does, and refactor it to replace oUF's :SetPosition with a user-defined one.

Note that a lot of the code you pasted handles updating as well, which won't really be needed anymore, as oUF does that already.

I'm sorry for my English and i'm not good enough at Lua

my question：
1：I make debuffs that cast by me bigger like this:

       local button = icons[index + offset]
               if icon.debuff and button.isPlayer then   
                       button:SetHeight(icons.size + 7)
                       button:SetWidth(icons.size + 7)
                       icon.overlay:SetVertexColor(0.9, 0.1, 0.1)
               else
                       button:SetHeight(23)
                       button:SetWidth(23)
                       icon.overlay:SetVertexColor(0.6, 0.6, 0.6)
       end

But the bigger debuffs and others are overlapping

2: I want there're four auras in the first and second row if targettarget, otherwize six per row.

Thanks very very mush.

I need some help

[Dawn]

Take a look at the code again, you need to adress the "offsetY" for new rows.

[lastgamer]

Hi，haste and Dawn，Thanks for the hint. But i'm a beginner，can you give me more suggestion？

Thank you.

[haste]

As mentioned earlier. You have to implement your own :SetPosition which handles icons with variable height/width.

There isn't really much more suggestions to give, without starting to write the code for you.

[lastgamer]

Thank you.
It's really a thorny problem.

[Dawn]

Take a look at this thread (the code is in one of the last posts).

click me


On a sidenote, desaturating non player debuffs is a more visible way without having to "mess" with this. Just my 2 cents.

Dawn, I wanna make ”thanks” bigger for you.
Thank you very mush,my friends.
