How do I do this in LUA or via another addon?

[Deleted]

Hi, I'm just trying to make a couple of modifications to the Align mod so it behaves like I want it to. Align basically puts a grid on your screen so you can more accurately move bits of the ui around

Here is a screenshot:



Just wondering if either anyone who knows lua might be able to suggest modifications to the code or if someone can suggest an alternative addon to do what I would want it to, thx.

1) only make the red line show up i.e. the huge crosshair centred on your character

2) modify the width of the red line and the height

3) only make the top of the four red lines appear

Thx for help.

Here is the entirety of the code:




local grid
local boxSize = 32

function Grid_Show()
if not grid then
Grid_Create()
elseif grid.boxSize ~= boxSize then
grid:Hide()
Grid_Create()
else
grid:Show()
end
end

function Grid_Hide()
if grid then
grid:Hide()
end
end

local isAligning = false
SLASH_TOGGLEGRID1 = "/align"
SlashCmdList["TOGGLEGRID"] = function(arg)
if isAligning then
Grid_Hide()
isAligning = false
else
boxSize = (math.ceil((tonumber(arg) or boxSize) / 32) * 32)
if boxSize > 256 then boxSize = 256 end
Grid_Show()
isAligning = true
end
end

function Grid_Create()
grid = CreateFrame('Frame', nil, UIParent)
grid.boxSize = boxSize
grid:SetAllPoints(UIParent)

local size = 2
local width = GetScreenWidth()
local ratio = width / GetScreenHeight()
local height = GetScreenHeight() * ratio

local wStep = width / boxSize
local hStep = height / boxSize

for i = 0, boxSize do
local tx = grid:CreateTexture(nil, 'BACKGROUND')
if i == boxSize / 2 then
tx:SetTexture(1, 0, 0, 0.5)
else
tx:SetTexture(0, 0, 0, 0.5)
end
tx:SetPoint("TOPLEFT", grid, "TOPLEFT", i*wStep - (size/2), 0)
tx:SetPoint('BOTTOMRIGHT', grid, 'BOTTOMLEFT', i*wStep + (size/2), 0)
end
height = GetScreenHeight()

do
local tx = grid:CreateTexture(nil, 'BACKGROUND')
tx:SetTexture(1, 0, 0, 0.5)
tx:SetPoint("TOPLEFT", grid, "TOPLEFT", 0, -(height/2) + (size/2))
tx:SetPoint('BOTTOMRIGHT', grid, 'TOPRIGHT', 0, -(height/2 + size/2))
end

for i = 1, math.floor((height/2)/hStep) do
local tx = grid:CreateTexture(nil, 'BACKGROUND')
tx:SetTexture(0, 0, 0, 0.5)

tx:SetPoint("TOPLEFT", grid, "TOPLEFT", 0, -(height/2+i*hStep) + (size/2))
tx:SetPoint('BOTTOMRIGHT', grid, 'TOPRIGHT', 0, -(height/2+i*hStep + size/2))

tx = grid:CreateTexture(nil, 'BACKGROUND')
tx:SetTexture(0, 0, 0, 0.5)

tx:SetPoint("TOPLEFT", grid, "TOPLEFT", 0, -(height/2-i*hStep) + (size/2))
tx:SetPoint('BOTTOMRIGHT', grid, 'TOPRIGHT', 0, -(height/2-i*hStep + size/2))

end

end

Here's my simple rewrite for a basic crosshair in the center of the screen that you can size.

This is drycoded (not tested) should you get any issues, I'm sure Treeston could help:
https://dl.dropboxusercontent.com/u/...nterScreen.zip

Simply type /crosshair 'thickness' and you'll create a crosshair of your desired thickness in the center of the screen.

local crosshair
local thickness = 4


function crosshair_Show()
	if not crosshair then
        crosshair_Create()
	elseif crosshair.thickness ~= thickness then
        crosshair:Hide()
        crosshair_Create()
    else
		crosshair:Show()
	end
end


function crosshair_Hide()
	if crosshair then
		crosshair:Hide()
	end
end


local isCrossing = false
SLASH_TOGGLECROSSHAIR1 = "/crosshair"
SlashCmdList["TOGGLECROSSHAIR"] = function(arg)
    if isCrossing then
        crosshair_Hide()
        isCrossing = false
    else
        thickness = tonumber(arg)
		crosshair_Show()
		isCrossing = true
	end
end


function crosshair_Create() 
	crosshair = CreateFrame('Frame', nil, UIParent) 
	crosshair.thickness = thickness 
	crosshair:SetAllPoints(UIParent) 


	local scale = UIParent:GetEffectiveScale()
	local width = GetScreenWidth()*scale
	local height = GetScreenHeight()*scale
	
	local centerX = width/2
	local centerY = height/2


	local v = crosshair:CreateTexture(nil, 'BACKGROUND')
	v:SetTexture(1,0,0,0.5)
	v:SetPoint("TOPLEFT", crosshair, "TOPLEFT", (centerX-(thickness/2)), 0)
	v:SetPoint('BOTTOMRIGHT', crosshair, 'BOTTOMLEFT', (centerX+(thickness/2)), 0)
	
	local h = crosshair:CreateTexture(nil, 'BACKGROUND')
	h:SetTexture(1,0,0,0.5)
	h:SetPoint("TOPLEFT", crosshair, "TOPLEFT", 0,(centerY+(thickness/2)))
	h:SetPoint('BOTTOMRIGHT', crosshair, 'TOPRIGHT', 0, (centerY-(thickness/2)))
	
end

Those leaked global functions make me sad

- - - Updated - - -

Also, I believe the OP only wanted the top line (the one from the top to the center of the screen) to appear.

Drycoded:

local crosshair

SlashCmdList["CROSSHAIR"] = function(c)
    local size = tonumber(c)
    if not size then print("Please use: /crosshair |cffff0000<size>|r") return end
    if crosshair and crosshair:IsShown() then
        crosshair:Hide()
        return
    end
    if not crosshair then
        crosshair = CreateFrame("Frame",nil,UIParent)
        crosshair:SetFrameStrata("TOOLTIP")
        crosshair:SetPoint("TOP")
        crosshair:SetPoint("BOTTOM",UIParent,"CENTER")
        crosshair:Hide()
        crosshair.tex = crosshair:CreateTexture(nil,"ARTWORK")
        crosshair.tex:SetAllPoints()
        crosshair.tex:SetTexture(1,0,0)
    end
    crosshair:SetWidth(size)
    crosshair:Show()
end
SLASH_CROSSHAIR1 = "/crosshair"

Thank you very, very much both of you Syronius and Treeston!

Yes I actually did just want a red line coming out from my character to the top of the screen that was slightly fatter than the current one.

Before I read your responses I actually ended up kind of figuring it out (I don't know a word of LUA :S) just by deleting and changing random numbers and lines from that mod until it worked. Good old fashioned trial and error!

This is what I got, but yours is a lot cleaner! You mentioned leaked global functions and I have a feeling this is full of them! But just posting for reference.

Thx again!
