Hello, I am wondering if anyone can point me in the right direction for making a simple script that will do the following. 1. Script is run 2. Script will wait until a certain color appears on screen. 3. Once the color is on screen, then the script will press a certain key such as "k" 4. Once "k" has been pressed, then sleep for 500 and then press "y" and then the script will repeat from step 1 and so on... Any help is appreciated, thanks in advance
