C++ Bot, Color Problem (No .NET)

[Freddy]

256 colors might eb the answer for you, don't know, for most games and such it's not that useful

I finally found out why it didn't work properly.

It only scanned X:0-815, and y stayed always 0.
But heres another Problem, it takes about 517 seconds to scan the whole screen, because, it takes roughly 1 Second to Scan x: 0-815, once x reaches 815 y = y +1;
Is there any way to make it faster?

EDIT:
With cout it takes 517 without cout it takes about half the time (I think).
Slowly I am having my doubts that this method (BitBlt) which I am using is good, Is there any better way to Search for Colors?

I've already tried:
GetPixel() - too slow
BitBlt()    - too slow



An Idea:
Is there a way to save all pixel Coords and Colors into a variable and then compare all of the data to a single color at once?

[Freddy]

GetPixel is indeed very slow, because it gets a single pixel and has to initiate new resources every time it is called... It's only worth using when you get a single pixel, or just a few at max.
BitBlt on the other hand is very fast and highly optimized, and irreplaceable unless you feel like writing a kernel mode driver

You can use CreateDIBSection and GetDIBits to get a pointer to the bits array of a bitmap, containing all pixel data. Might be a good idea to use scanlines, they're easy to use and pretty fast...

You might be able to pull something useful out of this: http://www.cplusplus.com/forum/windows/6353/

Basically Scanlines are arrays of colors, each scanline represents a row of pixels, so your index in the scanlines array should be your y value, then just the x value to get the color out of the scanline. The method used in that c++ thing is different from using CreateDIBSection, but does the same.

I'll get a look into scanlines, sounds promising.

I wanted to make a Similar Bot to RSBot only for Dark Orbit in C++. But I don't know how to do a Bot other than Color Search (which is difficult enough)
RSBot downloads all the Games data and uses it I have no idea how thats done... (how to download and use the data)

Is there a way you could download the Dark Orbit Data with SCAR and then let SCAR create a window which connects to the Dark Orbit Servers?
Like that I could get the Co-Ords of NPC's, Bonus Boxes ect. which is an advantage over Color Search.

I don't know if you plan on implementing something like that for SCAR in the future, but I hope you do.


My first step would be to download the data from the server, similar to runescape when it is loading.

It's unlikely, also, RSBot simply pulls data from variables inside of the RS client... Because of RS being made in java, this is a fairly easy thing to do...

Yea that makes sense...

Seems like in the future I will have to reverse engineer the Dark Orbit Protocols with Winsock, which isn't an easy task.

You can close this thread if you want.
