pawn Код:

new Float:playerpos[3];
    GetPlayerPos(playerid, playerpos[0], playerpos[1], playerpos[2]);

    for(new v = 0; v < MAX_VEHICLES; v++)
    {
        if(IsPlayerInRangeOfPoint(v, 4, playerpos[0], playerpos[1], playerpos[2]))
        {
            DestroyVehicle(v);
        }
    }

this doesnt work for me why

Because IsPlayerInRangeOfPoint takes a playerid as the first parameter, not the vehicle id.
If you want here is a working code for what you need, with a function called
'CheckPlayerDistanceToVehicle', so you can use that to check, or make your own by looking at it.

pawn Код:

stock CheckPlayerDistanceToVehicle( Float:radi, playerid, vehicleid )
{
    // Function: CheckPlayerDistanceToVehicle( Float:radi, playerid, vehicleid )

    new
        Float:vX, Float:vY, Float:vZ;

    GetVehiclePos( vehicleid, vX, vY, vZ );
    
    return IsPlayerInRangeOfPoint( playerid, radi, vX, vY, vZ );
}

Example of usage would be:

pawn Код:

CheckPlayerDistanceToVehicle( 3.5, playerid, vehid ) )

That checks if a player is in a 3.5 radius of the vehicle with the vehid as the vehicle id.
