Automatic Key press and image processing

Hi all, This project is related to a game (Rohan) and a mini fishing game played in it. The game consist in selecting a bate, clicking start and then a bar and a cursor start moving up and down. The cursor moves faster than the bar. The goal is to hit "space" when the cursor and the bar overlap. I need a software that can process my screen, or a portion of it, and send the "space" key when the bar and cursor overlap. Also this is a web based game, so there might be a little lag sending the stop command(the space key) to the server so I need the software to take this in consideration. Other functions I need from the software: * button to start/stop/pause (also key shortcuts like F9,F10,F11) * checkbox to take or not to take in consideration the lag * input box for manual lag entry * text to show lag, info on how many trys were made, how many were correct, how many not * if it will process only a part of the screen need an option to select or show the zone like desktop recording software Attached screen shot and video with mechanism. Any questions pls ask This must work on Windows 7. For the success of this project the software must hit a score of 10/20 (10 bar over cursor from 20 trys). If you want to install the game and test for your self you will need an account at [login to view URL] and download the client. I can show you the steps in game how to end up fishing, also if you need I can record a video with a longer time when the cursor moves. Ty for your time.
