I see the biggest use of a plugin like this for couch co-op party games. There's a few out there already that use this type of multiplayer setup.
One is Quiplash: http://store.steampowered.com/app/351510/
and the other is Fibbage:
but there's so many cool game ideas that could use the same sort of mechanics.
Imagine and RPG where the main screen is the dungeon where you encounter monsters, and each player on their tablet is an adventurer. You could design the game so that it encourages players to talk to each other and play off each other's characters talents etc. Each player could issue commands from their phone on when to attack/heal/buff etc.
There's another game out there that i forget the name of, but its a spaceship game where each player is a different crew member. One player is responsible for steering, while the next is in charge of shields etc. Each player has a completely different set of controls on their phone screen to deal with. You all have to work together to make the ship fly.
I can't wait to keep playing with this plugin even more.
OneMuppet - Few thoughts.....
1) Its spelled "Single" not "Signel" if you were trying to describe an action that takes place only once. Or perhaps you meant "Signal"
2) also, i'm not sure in the joystick controller event sheet (event 4) where there's a condition "Action ="j"
what's that being used for?
3) Is there a way of having more than 4 actions and 2 singleactions in a project?
Keep up the great work!
