 |
|
I don't get how you make a pixel based autopotter at all. I know how to get a pixel color and all that, but there can be many things of that color. I just don't get it. Can anybody explain to me?
By the way, I'm coding in delphi

A Pixel - based thing, lets just say determines what amount of red, blue and green is at a certain xy.
This way, we can pixel pot, and go such.
Im not sure about delphi, but in C++ its GetPixel, which is stored in a COLORREF variable.

Each color holds a Red value, Green value and Blue value, all values can be a minimum of 0 and max of 255: Where 0, 0, 0 is black and 255, 255, 255 is White.
GetPixel gets the pixel at a specific cursor position which will give you unique pixel value.
You can compare that to color's or even compare the Red/Green/Blue values using GetRValue/GetGValue/GetBValue and compare those.
It's better to check for pixels that are more constant rather than one that is different in certain positions.
In MapleStory, it would make more sense to check the series of grey pixels seeing as there's only like 5 or 6, instead of trying it to compare it to a entire blue or red gradiant.

Ya, but in and ms autopotter, it would be equally efficient to check to see if a certain pixel is "red" (more red than the others). <---its like fool proof

You don't check the entire screen. You select points along the HP bar (Normally 10% intervals) and check to see if those points are grey or red.

Ok I'm lost. As I said all I can do is find the red amount, green amount, and blue amount and the total color hex that the mouse is on or at a specified coordinate
Using Get Pixel then GetRValue and g and b of course :\

So use GetPixel on the fucking points on the HP bar. Then see if the value returned is equal to the value when it's red (meaning there's HP up to that point) or if it's equal to the value when it's gray (meaning there's no HP at that point).

Ok, I think I got it. I will finish the rest of the trainer first before I go to that part though Thanks!

That is all you need.
PColor = GetPixel()...blahblahblah
if (Red at PColor == 100 && blue at PColor == 0 && green at PColor == 0)
This is, of course not the right syntax, but the idea is the same.

Ok I got it now, but there are at least like 5 different reds and greys in there. Do you have a list of all the colors so I can make it any of them. By the way kitterz I'm doing it in delphi

I just picked a random red, blue and green value. You can set it to whatever you want, and the amount of red, blue and green differs according to pixel color.
1. A red pixel will have more red than grren and blue, etc
2. black will have 0,0,0 and white 255,255,255 (like lurc said)
This is an example in C++, though the concepts are the same.
| Code: | //Find Login Screen
for (;;) {
CColor = GetPix (GetDC(FindWindow("MapleStoryClass", NULL)),151,407 + YBase);
if ((GetRValue(CColor) == 68) && (GetGValue(CColor) == 170) && (GetBValue(CColor) == 34)) {
CColor = GetPix (GetDC(FindWindow("MapleStoryClass", NULL)),493,414 + YBase);
if ((GetRValue(CColor) == 204) && (GetGValue(CColor) == 170) && (GetBValue(CColor) == 102)) {
CColor = GetPix (GetDC(FindWindow("MapleStoryClass", NULL)),681,266 + YBase);
if ((GetRValue(CColor) == 34) && (GetGValue(CColor) == 17) && (GetBValue(CColor) == 0)) {
break;
}
}
}
else {
Sleep (100); //If Maple Closes B4 Login
}
} |
This, in C++ is what I made to find the login screen of maple. (Donnt critisize my coding any1 =p)
To get the amount of red, blue and green at a pixel, make a program that outputs the colors whenever you, say press F1.

Alright I made a timer that gives me the hex, but how come whenever I hover over Maplestory, the thing says its black after like a second after showing the colors. Also, I noticed that my screen resolution is different than other people, so how will I know what coord to put it on

Why not just use the RGB macro instead of that? So much simpler.
And why are you getting the DC OVER AND OVER AND OVER AND OVER?

why don't you get the pixel's color from a certain point at the hp bar,
after that create a thread that will get from the exact point the pixel's color again but to a different COLORREF variable
and then compare them each other like this
| Code: |
COLORREF color1,color2;
color1 = GetPixel(hdc,xPos,yPos); // hdc - device context of maple, xPos - X coord of certain point at hp bar, yPos - Y coord of certain point at hp bar
void AutoHPThread()
{
bQuit = FALSE;
while (!bQuit)
{
color2 = GetPixel(hdc,xPos,yPos); // same coordinates as color1
if (color1 != color2)
{
_PostMessage(hWnd,WM_KEYDOWN,<YourHpVirtualKey>,(MapVirtualKey(<YourHpVirtualKey>,0)) << 16);
}
}
ExitThread(0);
}
|
i guess it should work :S never tested it before
