i would like to create an MMORPG bot that will play while im away. I dont know how to ever start it or where to start from, can anyone give me any idea on how such kind of project can go? like a website about something alike? The game im trying to make it for is MMORPG that is played full screen with 100+ people... any help please. Thank you!

Try out www.easyuo.com if you want to see an example of one done for Ultima Online.

I''m taking a guess (from the way your post is worded) that you ahve never programmed before...if so, you are really waaaay ahead of yourself and need to learn basics first.

In order of quality:

1. Sniff the incoming packets and send faked ones.
Pros: Full control
Cons: Might be traceable

2. Sniff incoming packets and send window events to the game.
Pros: Full input control, not traceable
Cons: Limited output control.

3. Hook dll calls.
Pros: Not traceable
Cons: Limited control

4. Use dumb macros (ie. read pixel values and click here and there)
Pros: None.
Cons: Plenty.

5. Dont cheat.
Pros: Plenty.
Cons: Plenty.

But first of all buy a book called "How to become a scriptkiddie in 21 days for dummies."
