This is a engine to send or recieve messages. Host has to be active for the sending and recieving to work. To use this, remix this project and change the "Host" variable in the "Main" sprite to your username. Host has a different layout than a normal viewer.
This is a work in progress - things may look empty right now. May take a second or 2 to go through. Host active status may flicker due to me not putting all the cloud stuff in 1 variable, but if its flickering, or it says I'm online, then I am online. Thanks to @Dhananjaya for the Encode/Decode engine.
