Hey, for now, it's not possible; ShootingGame uses a very specific system that doesn't interact well with other plugins. I might look into a way to incorporate some of that plugin's functions into ShootingGame in the future.

Currently, the shootingGame plugin generates maps in a way that simulates a 3D environment, which directly conflicts with the 2D calculations produced by the cone system; in their current state, they are simply incompatible. Now that I know what you need, I’ll come up with a more elegant solution for the shootingGame.
