Spieler in Nähe von Krankenwagen ?

Ja kannst du:

stock IsBeiKrankenwagen(playerid)
{
new Float:x,Float:y,Float:z;
for(new i;i<MAX_VEHICLES;i++)
{
if(GetVehicleModel(i) == 520)//hier muss die krankenwagen modelid hin!
{
GetVehiclePos(i,x,y,z);
if(IsPlayerInRangeOfPoint(playerid,10,x,y,z))return 1;
}
}
return 0;
}
habs grad gescriptet also noch nicht getestet. Dann kannste einfach:

if(IsBeiKrankenwagen(playerid))
{
SendClientMessage(playerid,0x00ff00,"Du bist bei einem Krankenwagen!");
}

#define STANDART_RADIUS 18.8772

stock Float:GetVehicleDistanceFromPlayer(playerid, vehicleid)
{
new Float:Pos[6];
GetVehiclePos(vehicleid, Pos[0], Pos[1], Pos[2]);
GetPlayerPos(playerid, Pos[3], Pos[4], Pos[5]);
new Float:Distance = ( (Pos[3] - Pos[0])*(Pos[3] - Pos[0]) + (Pos[4] - Pos[1])*(Pos[4] - Pos[1]) + (Pos[5] - Pos[2])*(Pos[5] - Pos[2]) );
return Distance;
}

stock GetNearestVehicle(playerid)
{
new
Float:Pos[3],
Float:distance = STANDART_RADIUS,
id = INVALID_VEHICLE_ID;
GetPlayerPos(playerid, Pos[0], Pos[1], Pos[2]);
for(new i=0; i<MAX_VEHICLES; i++) if( GetVehicleModel(i) && (IsPlayerInRangeOfPoint(playerid, STANDART_RADIUS, Pos[0], Pos[1], Pos[2])) && (GetVehicleDistanceFromPlayer(playerid, i) < distance)) { distance = GetVehicleDistanceFromPlayer(playerid, i); id = i; }
return id;
}

stock IsNearAmbulance(playerid)
{
return (GetVehicleModel(GetNearestVehicle(playerid)) == 416) ? (1) : (0);
}
