[Help]bot creation

so far i made prograss with AutoIt and made a fishing script wich works, but is coordites are on my pc and it not always does what it should when  it should. the getpixelcolor function is slow and makeing it syncronise is hard, i was looking for tips from you guys on general and specific methos of creating bots, perhaps even some tips on interacting with client software for real and sending packages without the client, my server uses bakeice to lunch interlude, but my progress is slow, and in this rate is not very much worth it, so i look for a speedup from you... thx
