I am trying to learn how to write bots, specificaly a bot for a game called Rappelz but had no idea where to start so I was doing research into maphacks for WC3. I assume learning how MH works will in the end help me achive my goal... In any case it seems that offsets are crutial in doing this but I cannot find any information about how they work.

Can anyone link me resources or tell me where to start looking to learn more about offseting?
- Thanks
