Get correct scaling of pixels

[Cashless]

Hi,

I am also trying to program a pixelbot, but it fails to read the pixels correctly.

I create the pixels using an addon.

local uiScale = UIParent:GetEffectiveScale()
print("UI Scale: " .. uiScale)
local squareSize = 5*uiScale
local function createSquare(xOffset)
    local square = CreateFrame("Frame", nil, UIParent)
    square:SetSize(squareSize, squareSize)
    square:SetPoint("TOPLEFT", xOffset, 0)
    square.texture = square:CreateTexture(nil, "BACKGROUND")
    square.texture:SetAllPoints(true)
    square.texture:SetColorTexture(1.0, 1.0, 1.0, 1.0)
    return square
end

local TestPixel = createSquare(squareSize)

What I expect now: Pixel extends from pixel 6-10 in the WoW window.
What it actually is: from pixel 6 to 16 or they overlap. It is kind of messy

How do I calculate the actual positions of the pixels?

when I did a pixelbot I wanted to have 1 pixel just per box so I didn't use ui scaling, it was possible to get 1:1 ratio with scaling turned off I think. might be easier, then your bot can screengrab a small poortion , just what it needs, I mean a few pixels can be enough for a simple grind bot

for example writing the wow addon so it puts the pixels in top-left corner, then screengrab and zoom in and see if it's correct

But how did you created just 1pixel?

local MyFrame = CreateFrame("Frame")

local Box = CreateFrame("Frame", nil, UIParent)
Box:SetFrameStrata("FULLSCREEN_DIALOG")
Box:SetSize(1, 1)
Box:SetPoint("TOPLEFT", 0, 0)
Box.Texture = Box:CreateTexture(nil, "BACKGROUND")
Box.Texture:SetAllPoints(true)

local combat = false

MyFrame:RegisterEvent("PLAYER_REGEN_DISABLED")
MyFrame:RegisterEvent("PLAYER_REGEN_ENABLED")

MyFrame.elapsed = 0.125
MyFrame:SetScript("OnUpdate", function(self, elapsed)
self.elapsed = self.elapsed - elapsed
if self.elapsed > 0 then return end
self.elapsed = 0.01

local r = 1
local g = 1
local b = 1

if combat then r = 255 end
if UnitCastingInfo("player") ~= nil or UnitChannelInfo("player") ~= nil then g = 255 end
if UnitGUID('target') ~= nil then b = 255 end
Box.Texture:SetColorTexture(r/255,g/255,b/255,1);
)

MyFrame:SetScript("OnEvent",function(self,event,msg,msg2,msg3,msg4,...)
if event=="PLAYER_REGEN_DISABLED" then
combat = true
elseif event=="PLAYER_REGEN_ENABLED" then
combat = false
end
end
)

like this you could easily make a rotation bot for example...
extract what keybind HeroRotation suggest and code it into a pixel and then read it with some python code and press the correct bind.

Thank you very much!
So yeah, one pixel is working fine, but if I create more than one pixel, its gonna be difficult, because I dont have the exact position or WoW isnt that pixel correct
Like

local TestPixel = createSquare()
TestPixel:SetPoint("TOPLEFT",0,0,0)
local PlayerLevel = createSquare()
PlayerLevel:SetPoint("LEFT",TestPixel,"RIGHT",0,0)
local PlayerHealth = createSquare()
PlayerHealth:SetPoint("LEFT",PlayerLevel,"RIGHT",0,0)
local PlayerMaxHealth = createSquare()
PlayerMaxHealth:SetPoint("LEFT",PlayerHealth,"RIGHT",0,0)

Box:SetSize(1, 1)

It is not 1 pixel anymore. Even if I change the resolution from 4k to 1080p, it is not predictable

well my code works.. I don't know what your createSquare() looks like.. I see you fully haven't undestood this anyways.
Why are you creating more squares and setting them to the same location? Good luck.
