Useful Functions
Because the old topic was deleted, i got permission to create a new 'Useful Functions'-topic.
In this topic you can post selfmade functions.

Rules:



Re: Usefull Functions - Yaheli_Faro - 05.06.2008

CagePlayer(playerid);
this is function does the same as my /cage command in V-Admin (puts a player in a cage :P).

pawn Code:
// Top of script
new cage[MAX_PLAYERS], cage2[MAX_PLAYERS], cage3[MAX_PLAYERS], cage4[MAX_PLAYERS], caged[MAX_PLAYERS];

// new function
stock CagePlayer(playerid)
{
      if(IsPlayerConnected(playerid))
      {
      new Float:X, Float:Y, Float:Z;
      GetPlayerPos(playerid, X, Y, Z);
      cage[playerid] = CreateObject(985, X, Y+4, Z, 0.0, 0.0, 0.0);
      cage2[playerid] = CreateObject(985, X+4, Y, Z, 0.0, 0.0, 90.0);
      cage3[playerid] = CreateObject(985, X-4, Y, Z, 0.0, 0.0, 270.0);
      cage4[playerid] = CreateObject(985, X, Y-4, Z, 0.0, 0.0, 180.0);
      caged[playerid] = 1; // Use this in a /cage command to prevent being caged twice and causing the cage to be unremovable.
      PlayerPlaySound(playerid, 1137, X, Y, Z);
      }
}
UnCagePlayer(playerid);
This will remove the cage

pawn Code:
stock UnCagePlayer(playerid)
{
      cage[playerid] = DestroyObject(cage[playerid]);
      cage2[playerid] = DestroyObject(cage2[playerid]);
      cage3[playerid] = DestroyObject(cage3[playerid]);
      cage4[playerid] = DestroyObject(cage4[playerid]);
      caged[playerid] = 0;
}


Re: Useful Functions - Rafelder_GRF - 05.06.2008

DisableBadWord(word[])
word[] - word which will be disabled
pawn Code:
#define DisableBadword(%1) for(new i=0; i<strlen(text); i++) if(strfind(text[i], %1, true) == 0) for(new a=0; a<256; a++) if (a >= i && a < i+strlen(%1)) text[a]='*'

Thanks, i fixed typo now

SendClientMessageToAllEx(exception, color, const message[])
This function sends a message to all players, except for 1 player. (exception)

Code:
stock SendClientMessageToAllEx(exception, color, const message[])
{
  for(new i; i<MAX_PLAYERS; i++)
  {
    if(IsPlayerConnected(i))
 	{
	  if(i != exception)
	  {
	    SendClientMessage(i, color, message);
	  }
	}
  }
}
GetVehicleDriver(vehicleid)
Returns the ID of the player driving in the vehicle. Returns '-1' if nobody is driving in the vehicle.
Code:
stock GetVehicleDriver(vehicleid)
{
  for(new i; i<MAX_PLAYERS; i++)
  {
    if (IsPlayerInVehicle(i, vehicleid))
    {
      if(GetPlayerState(i) == 2)
      {
    		return i;
      }
	}
  }
  return -1;
}

Need a 'c' in "if(i != ex©eption)"

Re: Usefull Functions - Y_Less - 05.06.2008

Gotta love Kye deleting my account and thus all the topics that went with it. Anyway, some of my useful functions I've made over the years have been ported to YSI and put in the YSI_misc.own file. The file can be found:

here

Functions include:

swap(var1, var2) - Swap two variables without a third variable.
xor:==xor: - Do a logical xor check on two variables.
ceildiv - Divide two integers and round up.
isnull - Used for empty strings passed via CallRemoteFunction.
iseven - Obvious.
isodd - Obvious.
floordiv - Rounded down integer division.
chrfind - Find a single character in a string, faster than strfind for single characters.
chrnfind - Find the end of a set of characters in a string (for example to skip a set of spaces).
strcpy - Copy a string.
bernstein - Like Adler32 hash but faster and less collisions.
bernstein_copy - Mix of strcpy and bernstein for speed.
StripNL - Similar to PHP's rtrim.
strconcat - Stick two strings together.
QuickSort - Call wrapper for QSort, sorts an array into newmerical order.
QSort - Workhorse recursive function for QuickSort.
chrtolower - Convert a character to lowercase.
strtolower - Convert a string to lowercase.
hexstr - strval for hex strings.
binstr - Checks if a string is "0" or "false".
ReturnPlayerName - Obvious.
ishex - Checks if a string is hexadecimal.
numstr - Converts a number to a string, should use valstr but doesn't.
chrtoupper - Convert a character to upper case.
strtoupper - Convert a string to upper case.
timestamp - Get the unix timestamp for the current time.
mktime - Get the unix timestamp for a given time.
GetIP - Return a player's IP as a 32bit integer.
getintpar - Gets a number from a string apparently.
IsConnected - Like IsPlayerConnected but uses YSI's internal foreach system.
KickDelay - Kick a player after a given amount of time. Used to ensure they get the message sent.
KickDelayCall - public function KickDelay calls.
BanDelay - Like KickDelay but ban.
BanDelayCall - Like KickDelayCall but ban.
endofline - Checks if the current position is the end of non-whitespace data.
isnumeric - Checks if a string is numeric.
abs - Returns the absolute (positive) value of a number.
sscanf - Deserves (and has) it's own tutorial on use.
explode - Like PHP's explode function.
IsPlayerInRangeOfPoint - Checks if a player is near a point without calling floatsqroot for speed.

The library also has a couple of useful variables:

TRUE - Always true, used for infinate loops.
FALSE - Always false, used for large code macros.
NULL - The string passed instead of an empty string by CallRemoteFunction due to the way the PAWN VM works.

Isn't this the same as Yom's "SendClientMessageToAllOthers"?

The name will be stored in "PlayerName" variable!
pawn Code:
stock GetName(playerid)
{

  GetPlayerName(playerid, PlayerName, sizeof(PlayerName));
  return PlayerName;
}
Have you tried compiling that?

Also:
pawn Code:
printf("KickEx(): %s(%i) kicked, reason: %s", PlayerName, playerid);
Should be
pawn Code:
printf("KickEx(): %s(%i) kicked, reason: %s", PlayerName, playerid, reason);
right?

And also, it seems you are using your own GetName function wrongly, you say its GetName(playerid, variable) in the NameCheck() thing, yet it is actually GetName(playerid).

Re: Usefull Functions - Grove - 05.06.2008

Admin(msg) - Sends a message to the online rcon admins!
Code:
stock Admin(msg[])
{
  for(new i 0; i<GetMaxPlayers(); i++
  {
    if(IsPlayerConnected(i) && IsPlayerAdmin(i)) SendClientMessage(i,white,msg);
  }
}

Ok, well your half way there. But it still wont work, GetName(playerid) directly returns the players name, so it could be used like:
pawn Code:
printf("Name: %s", GetName(playerid));
It wont work because you just call it so it gets the players name (yet you dont catch what it returns), then you try and read the NON Global variable...

Re: Useful Functions - boemeles - 05.06.2008

In addition to Andre:
NOTE! this is not made by me, i dont take any credits!

use this in your script:
pawn Code:
if(!IsPlayerInInvalidNosVehicle(playerid, vehicleid) //notice the "!"
pawn Code:
//----------[ IsPlayerInValidNosVehicle made by [fackin']luke]---------------------
IsPlayerInInvalidNosVehicle(playerid,vehicleid)
{
  #define MAX_INVALID_NOS_VEHICLES 29

  new InvalidNosVehicles[MAX_INVALID_NOS_VEHICLES] =
  {
    581,523,462,521,463,522,461,448,468,586,
    509,481,510,472,473,493,595,484,430,453,
    452,446,454,590,569,537,538,570,449
  };

  vehicleid = GetPlayerVehicleID(playerid);

  if(IsPlayerInVehicle(playerid,vehicleid))
  {
        for(new i = 0; i < MAX_INVALID_NOS_VEHICLES; i++)
        {
          if(GetVehicleModel(vehicleid) == InvalidNosVehicles[i])
          {
            return true;
          }
        }
  }
  return false;
}
// end of it!


Re: Useful Functions - Luk0r - 06.06.2008

CheckPlayerName - checks a string to ensure it follows the traditional Firstname_Lastname roleplay name format

Returns:
0 - Invalid roleplay name
1 - Valid roleplay name

pawn Code:
CheckPlayerName(const name[]) // by Luk0r
{
    if (strlen(name) < 6) return 0;
    if (strfind(name, "_", true) == -1) return 0;
    new underscorecount, expectinguppercase = 1;
    for (new i = 0, j = strlen(name); i < j; i++)
    {
        if (expectinguppercase == 1)
        {
            if (name[i] < 'A' || name[i] > 'Z') return 0;
            expectinguppercase = 0;
            continue;
        }
        switch (name[i])
        {
            case '_':
            {
                if (underscorecount == 1) return 0;
                else
                {
                    underscorecount = 1;
                    expectinguppercase = 1;
                }
                continue;
            }
            case 'A' .. 'Z': continue;
            case 'a' .. 'z': continue;
            default: return 0;
        }
    }
    return 1;
}


Re: Useful Functions - boemeles - 06.06.2008

Again: to complete andre's list: IsABoat

IsABoat(carid)
carid - Vehicle ID that we check
pawn Code:
stock IsABoat(carid)
{
  new Operative[] = { 472, 473, 493, 495, 484, 430, 454, 453, 452, 446 };
  for(new i = 0; i < sizeof(Operative); i++)
  {
    if(GetVehicleModel(carid) == i) return 1;
  }
  return 0;
}

Thank you.
I hope you don't mind - I added to my post with your credit and link to your account of course.
no problem, you could clearly see i used your layout!

Re: Useful Functions - boylett - 06.06.2008

RPName
Returns first and last name of an RP style name (e.g. John_Bortch will return John and Bortch). It returns 0 if the RP Name isnt valid

Code:
RPName(name[],ret_first[],ret_last[])
{
	new len = strlen(name),
		point = -1,
		bool:done = false;
	for(new i = 0; i < len; i++)
	{
	  if(name[i] == '_')
	  {
	    if(point != -1) return 0;
	    else {
				if(i == 0) return 0;
				point = i + 1;
			}
	  } else if(point == -1) ret_first[i] = name[i];
	  else {
			ret_last[i - point] = name[i];
			done = true;
		}
	}
	if(!done) return 0;
	return 1;
}
Usage:
Code:
public OnPlayerConnect(playerid)
{
	new name[MAX_PLAYER_NAME], first[MAX_PLAYER_NAME], last[MAX_PLAYER_NAME], ret;
	GetPlayerName(playerid,name,sizeof(name));
	if(RPName(name,first,last))
	{
		// Valid name, player is called first_last
	} else {
	  // Invalid name, deal accordingly
	}
	return 1;
}
strtok
Code:
strtok(string[],&idx,seperator = ' ')
{
	new ret[128], i = 0, len = strlen(string);
	while(string[idx] == seperator && idx < len) idx++;
	while(string[idx] != seperator && idx < len)
	{
	  ret[i] = string[idx];
	  i++;
		idx++;
	}
	while(string[idx] == seperator && idx < len) idx++;
	return ret;
}
rand
An exact copy of the function "rand" in PHP.

pawn Code:
rand(minnum = cellmin,maxnum = cellmax) return random(maxnum - minnum + 1) + minnum;
GetVehicleName
Returns the vehicle name from a modelid.

Float:GetPointDistanceToPoint
pawn Code:
Float:GetPointDistanceToPoint(Float:x1,Float:y1,Float:x2,Float:y2)
{
  new Float:x, Float:y;
  x = x1-x2;
  y = y1-y2;
  return floatsqroot(x*x+y*y);
}
Float:GetPointDistanceToPointEx
pawn Code:
Float:GetPointDistanceToPointEx(Float:x1,Float:y1,Float:z1,Float:x2,Float:y2,Float:z2)
{
  new Float:x, Float:y, Float:z;
  x = x1-x2;
  y = y1-y2;
  z = z1-z2;
  return floatsqroot(x*x+y*y+z*z);
}

{
    if(!IsPlayerInAnyVehicle(playerid) && vehicleid > 399 && vehicleid < 612)
    {
        new Float:x, Float:y, Float:z, Float:a, vehicle;
        GetPlayerPos(playerid, x, y, z);
        GetPlayerFacingAngle(playerid, a);
        vehicle = CreateVehicle(vehicleid, x, y, z, a, -1, -1, 50000);
        PutPlayerInVehicle(playerid, vehicle, 0);
    }
}
saves a lot of time when u need to to do this eveytime you want to spawn a vehicle!

SafeKill(playerid);
Makes you spawn without losing weapons
pawn Code:
stock SafeKill(playerid)
{
  new Weapons[MAX_PLAYERS][11], Ammo[MAX_PLAYERS][11]; // news
  for(new j=0; j<11; j++)   GetPlayerWeaponData(playerid, j, Weapons[playerid][j], Ammo[playerid][j]);// loop through all weapon slots + ammo
  SpawnPlayer(playerid); //respawn the player
  for(new j=0; j<11; j++)   GivePlayerWeapon(playerid, Weapons[playerid][j], Ammo[playerid][j]);// loop through all weapon slots + ammo
}
yes, i know this can be abused, but i made this keeping in mind how stupid it is to somehow be stuck, do /kill, and have to start all over...

Shouldn't it be:
Code:
return i;
instead of
Code:
return vehicleid;
??
