About that circule you can use the stock I gave you
[/pawn] If(IsPlayerInRangeOfPoint(playerid, 5.0, x,y,z)) Force(playerid); [/pawn]

As for the "player2" shooting from a vehicle you can use

pawn Код:

OnPlayerKeyStateChange

And then check if the player is hold a weapon and clicking FIRE while he close to the "Force" stock.
