For educational reasons, not any in special, I don't want to bypass any security I just want to know the general development of a bot, tell me what you know about it.
This depends on the game, give more specific details.
There are at least 2 general kinds of bots, those that hook into the game and issue automated commands through it ( or those that don't even hook into the game, but issue commands by messages ), or those that knowing the full protocol of the game (this means being able to emulate security checks too) you simply write a simplified client which is then connected to some simple AI engine which executes whatever instructions you want the bot to do.
