If something is wrong please tell me in the comments This may not be what you're looking for but I can't really say you were clear on instructions. This involves a sprite called the commander, it changes a variable and then sends a message. When the message is sent it will receive it and look for it in the command list. If it's there, it will do... something? If you wanted me to ONLY use variables and not include any form of messaging I can gladly do so if you notify me.
