Admin Lock

pawn Code:
new aVehicle; //Above Main
pawn Code:
//gamemodeinit
aVehicle = AddStaticVehicle(598,2256.0903,2477.0115,10.5668,178.5022,0,1); //gamemodeinit
pawn Code:
public AdminLock(playerid) //Anywhere in script
{
 if(IsPlayerConnected(playerid))
 {
   if(IsPlayerAdmin(playerid))
   {
    SetVehicleParamsForPlayer(aVehicle, playerid,0,0);
   }
   else
   {
    SetVehicleParamsForPlayer(aVehicle, playerid,0,1);
   }
 }
}
pawn Code:
public OnPlayerSpawn(playerid)
{
   AdminLock(playerid);
   return 1;
}
pawn Code:
AddStaticVehicleEx(598,2256.0903,2477.0115,10.5668,178.5022,0,1,never);

Well this is a small thing but i find it a bit more efficient,

instead of using for(new i=0;i<MAX_PLAYERS

I use this:

Code:
new maxplayers; //Global Variable

public OnPlayerConnect(playerid){
	if(playerid > maxplayers-1) maxplayers = playerid+1; //Getting the maximum playerid
}

public OnPlayerDisconnect(playerid){
	if(playerid == maxplayers+1) for(new i=0;i<maxplayers;i++) if(IsPlayerConnected(i)) maxplayers = i+1; //Getting the minimum playerid
}

for(new i=0;i<maxplayers;i++) //the new more efficient loop

That won't work, you're assuming that all players are consecutive, which is rarely the case, you could have 10 players max, but only players 1, 4, 7 and 9 connected, which would make the max thing 9, saving almost nothing, and you would still need to check for connection.

No I'm not assuming there consecutive, check my code again, i find the highest playerid according to OnPlayerConnect and make the max loop that, then when a player disconnects i reevaluate the highest playerid

since basically all MAX_PLAYERS loops try to loop according to playerids you only need the highest one, hence this is more efficient

ok about the admin vehcile's
i added 13 admin vehicle's and i can open them when im not admin.. now i realized that i had to add this, before it would work:

Code:
AddStaticVehicleEx(425,2137.0598,1729.9246,20.5675,59.3952,0,1,never);
    AddStaticVehicleEx(522,2164.1125,1720.9868,20.1695,161.4324,0,1,never);
	AddStaticVehicleEx(522,2168.9771,1719.4484,19.9998,169.0915,0,1,never);
	AddStaticVehicleEx(522,2174.8657,1718.4332,20.1868,165.7749,0,1,never);
	AddStaticVehicleEx(522,2179.6699,1717.1212,19.9994,166.9654,0,1,never);
	AddStaticVehicleEx(444,2208.9463,1654.0419,20.0004,2.0738,0,1,never);
	AddStaticVehicleEx(556,2184.9636,1654.0623,20.0956,2.9973,0,1,never);
	AddStaticVehicleEx(425,2201.3828,1716.8575,34.2190,88.4603,0,1,never);
	AddStaticVehicleEx(520,2141.1396,1637.6151,20.1024,120.4169,0,1,never);
	AddStaticVehicleEx(541,2175.4431,1613.0690,20.0886,182.6934,0,1,never);
	AddStaticVehicleEx(411,2168.8147,1614.7198,20.0885,181.9470,0,1,never);
	AddStaticVehicleEx(451,2163.6968,1613.2709,20.0878,175.1219,0,1,never);
	AddStaticVehicleEx(447,2141.5942,1591.2502,31.6095,124.6433,0,1,never);
And get this error:

Code:
(19229) : error 021: symbol already defined: "AddStaticVehicleEx"
I searched thru the forums how i could fix this error but found nothing.

Everybody needs sleep Code


pawn Code:

        Info[i] [Tired] = 1;
        Info[i] [Awake] = 0;
        Info[i] [Sleeping] = 0;
    }
}
pawn Code:

Why not simply:

pawn Code:
if ( IsPlayerInCube(i,2236,-1076,1040,2245,-1066,1100) || IsPlayerInCube(i,2202,-1070,1000,2211,-1078,1100) )
So you can delete half of the timer func. Also check if they are connected before doing anything.

Something like this

pawn Code:
#define MAX_VEHICLES 255 //amount of cars in script
new aVehicle[MAX_VEHICLES] //define of aVehicle
pawn Code:
new never = 1000000;
    aVehicle[1] = AddStaticVehicleEx(522,2164.1125,1720.9868,20.1695,161.4324,0,1,never);
    aVehicle[2] = AddStaticVehicleEx(522,2168.9771,1719.4484,19.9998,169.0915,0,1,never);
pawn Code:
public AdminLock(playerid) //Anywhere in script
{
  if(IsPlayerConnected(playerid))
  {
   if(IsPlayerAdmin(playerid))
   {
     SetVehicleParamsForPlayer(aVehicle[MAX_VEHICLES], playerid,0,0);
   }
   else
   {
     SetVehicleParamsForPlayer(aVehicle[MAX_VEHICLES], playerid,0,1);
   }
  }

Admin Area
pawn Code:
// Set the timer triggering the function which checks if players are in the 'admin' area

SetTimer("AreaCheck", 1000, 1);

// The function

AreaCheck()
{
    for(new i=0; i<MAX_PLAYERS; i++ ) {
        if(IsPlayerConnected(i) && IsPlayerInArea(i, minx, maxx, miny, maxy) && !IsPlayerAdmin(i)) // CHECK: If the player is a admin, if the player is in the area
        { // He's not.
            SendClientMessage(i, YOURCOLOR, "You are not allowed to enter the ADMIN area.");
            /* Do with him whatever
                you want */

        }
    }
}

// ISPIA Function

IsPlayerInArea(playerid, Float:minx, Float:maxx, Float:miny, Float:maxy)
{
new Float:x, Float:y, Float:z;
GetPlayerPos(playerid, x, y, z);
if (x > minx && x < maxx && y > miny && y < maxy) return 1;
return 0;
}
Since it's something most newb scripters want to have, and "cant" find it, i'll post a very basic one. Hopefully this will stop some of the 'I cant find a working code' bs.

Dunno what the function IsPlayerInArea does when you try to check for a playerid that is not connected.... Since that's what's gonna happen sooner or later: you will not always have a full 100 player load on your server.

Added OnPlayerConnect for Flame^'s Snippet.

pawn Code:
SetTimer("AreaCheck", 1000, 1);
// The function
pawn Code:
AreaCheck()

Could you give an example of how it could be used? For instance in a str2bin(string[])? I think this could be really useful
