I have this game and when u press the green flag it comes up with play. once u press it it comes up with two options. plane or ground. press ground and watch. the bullet want go to my enemy and I don't understand because it is the exact same as the enemy is the plane.

Thanks!

Try making the player receiving all broadcasts.

when I receive [Ground]

What on earth do you think a script like this is doing?

when I receive [ground v]
forever
stop [this script v]
end

It recieves a broadcast and stops itself - the forever loop is irrelevant. It's equivalent to the script below (yes I know there's nothing there, that's the point!).

You're not currently broadcasting Ground, only GroundReady.

when green flag clicked
forever
go to [Imagine v]
say [Program]
play sound [Share v]

end

Opps, wrong place

when green flag clicked
forever
go to [Imagine v]
say [Program]
play sound [Share v]

end
