Re: car check near player - prineside - 02.11.2015

Function stops working after "return".

Let's run your code:
We have2 vehicles:
ID 1 - far away from you
ID 2 - near you

Your script looks first at ID 1, then at ID 2. When it looks at ID 1 (the car is far away), it returns 1 and sends that message.

To do it right, you should do this in another way (for example, if you want to get the first car with smallest ID nearby):
PHP код:
   new Float: P[3];
   GetPlayerPos( playerid, P[0], P[1], P[2] );

   new vehiclesNearby = 0;
   for (new v; v < MAX_VEHICLES; v++) {
      if ( GetVehicleDistanceFromPoint( v, P[0], P[1], P[2] ) <= Radius ) {
         // There's a vehicle nearby
         vehiclesNearby = 1;
         break;
      }
   }

   if ( vehiclesNearby == 0 ) {
      SendClientMessage(playerid, -1, "Car isnt near");
   } else {
      SendClientMessage(playerid, -1, "Car near you. you can do what you wanna ");
      // ...
   }
