Creating a Pixel Bot in C# from zero - "kinda" tutorial

Olha um portugues!

Instead of having actual color codes, use a texture along with SetTexCoord.
It does the trick.

Do you mean using hundreds of pictures with different colors in them? And then having the addon to change the picture of the texture instead of just changing the color with SetColorTexture?

Hello, the weakaura works for me outside of BGs, but in AV it stops working, anyone who has the same issue can help me ?

Nice! I finally got it reading the pixels:

You have to read memory to do stuff in instances and BG's. Blizzard did that to prevent bots that can farm instances all day, but instance farming is pretty dead now anyways compared to the actual lucrative stuff. I think Interact with target is also disabled in BG's, so that multiboxers can only do their thing in the open world. You have to have pure math based steering if you want to pixel bot in instances. You could in theory use some of the ideas like a target marker being read along lua error messages to do it, but you might as well focus that energy on a memory bot at that point.

Thanks for your reply hycolyte, i will dedicate some months in creating a pixel bot without reading memory to leech av honor but mostly to learn, if anyone has any source code he can share with me i would like to see it for learning purposes only

On second thought I found there are ways to still face your target in AV. There are several quest items that exist in retail at least (not sure about classic) that will face your target. Certain spells also have this behavior. However, I don't think there is a way to get your coords, so you would be without navigation.

How should I send keypresses though? I get disconnected from using PostMessage after like 5 minutes. Maybe it's something else, I can't properly diagnose it.

Update edit: the disconnects seem to be from immediately interacting with a new target while turning with virtual keypresses. Humanized timing/safe randoms didn't matter it was simply turning/interacting together that would disconnect.

I was able to get it working as a blazor app

I stumbled across this post and since i dabble with programming from time to time I decided to see what I could do with the information provided. I actually surprised myself with the progress I have made. I am able to record and follow a route. The bot will check for targets periodically and when it finds one will engage in combat. I did not plan out my code or have any idea what I was getting myself into and its starting to become difficult to make sense of it. I spent far too long writing the algorithm to turn the player the shortest direction especially across the 0/360 degree value. I believe I need to implement some FSM but I still don't understand them. Just wanted to say thanks for the information here and leave my two cents.

Here are some important functions I use you might find helpful for turning:

Turn

public void Turn(object sender)
{
    if (!GameData.HasTarget)
    {
        var turnDegrees = GetTurnDegs(DegToTarget(Next));

        bool turnRight = GetTurnDir(turnDegrees.Item1, turnDegrees.Item2);

        int turnTime;

        if (!turnRight)
            turnTime = GetTurnTime(turnDegrees.Item1);
        else
            turnTime = GetTurnTime(turnDegrees.Item2);

        KeyWrap turnKey;

        if (turnRight)
            turnKey = Keys.TurnRight;
        else
            turnKey = Keys.TurnLeft;

        if (turnTime > MIN_TURN_TIME)
        {
            turnKey.PressKey(ID);
            Thread.Sleep(turnTime);
            turnKey.ReleaseKey(ID);
        }
    }
}

Turn Functions

int DegToTarget(PointF point)
{
    var angle = Math.Atan2(Location.X - point.X, Location.Y - point.Y);

    var degree = angle * 57.2958;
    degree = degree % 360;

    return (int)degree;
}

Tuple<int, int> GetTurnDegs(int degToTarget)
{
    int facing = Facing;

    int degreesLeft = degToTarget - facing;
    int degreesRight = facing - degToTarget;

    if (degreesLeft < 0) degreesLeft += 360;
    if (degreesRight < 0) degreesRight += 360;

    return new Tuple<int, int>(degreesLeft, degreesRight);
}

bool GetTurnDir(float degreesLeft, float degreesRight)
{
    return degreesRight < degreesLeft ? true : false;
}

int GetTurnTime(int turnDegrees)
{
    float radians = (float)(turnDegrees * 0.0174533);

    return (int)(1000 * (radians / Math.PI));
}

Nice, this is what I settled on after a couple hours in bed awake one night after having too much caffeine.

            // CALCULATE ANGLE
            double r = Math.Atan2(-target.Y, target.X); // Radians, WoW is Y+ down so invert the Y value
            double a = r * (180 / Math.PI); // Convert radians to degrees
            a = (a < 0) ? a += 360 : a; // Convert to 360 instead of 180-(-179)

            double f = player.Facing; // Angle the player is facing in degrees
            double error = f - a;
            if (Math.Abs(error) > 180)
            {
                f = (f < a) ? player.Facing + 360 : player.Facing - 360;
                error = f - a; // Recalculate the error for the new angle
            }

If the error is negative i turn the player left, if its positive i turn the player right instead.

Thank you for the pixel bot idea with c# but i am missing the function that decodes the RGB colour. Anyone who can help me pls?

Thank you for the pixel bot idea with c# but i am missing the function that decodes the RGB colour. Anyone who can help me pls?

int ColorToInt(Color color)
{
    return (int)(Math.Pow(256, 2) * color.R + 256 * color.G + color.B);
}

And this is what I use for the lua code to generate the RGB int

function IntToRGB(n) 
   if n >= (math.pow(256,3)) then -- 16777215 is the MAX_RGB_INT
      error("Can't encode integer (too large)")
   end
   
   local r = math.floor(n / 65536)
   local g = math.floor(math.fmod(n / 256, 256))
   local b  = math.floor(math.fmod(n, 256))
   
   -- RGB percent conversion
   return { r = r / 255, g = g / 255, b = b / 255 }
end

thank you so much! It works like a charm
