No, he's right. It shouldn't be like that but it is in San Andreas - https://sampwiki.blast.hk/wiki/SetPlayerFacingAngle

Re: Useful Functions - StrickenKid - 08.12.2009

Someone should really change that wiki page so newbs don't get mixed up...

Re: Useful Functions - LarzI - 09.12.2009

[size=14px]GetPlayerPosInt(playerid, &Float, &Float:y, &Float:z, &interior);[/size]
playerid - id of the player you want to return values from.
&Float, &Float:y, &Float:z, &interior - variables for x-coord, y-coord, z-coord and interior

pawn Код:

stock GetPlayerPosInt(playerid, &Float:x, &Float:y, &Float:z, &interior)
{
  GetPlayerPos(playerid, x, y, z);
  interior = GetPlayerInterior(playerid);
}

Should work, lol xp

EDIT: Thanks Seif_ :P

Re: Useful Functions - thegoliathmaster - 15.12.2009

Hi,

this is something everyone knows, but i HATE the usual implementation, so i made one, it is faster btw (takes about 2/3 of the original time)

Код:

stock strtok(const source[], &index, dest[], separator = ' ')
{
	new i = 0;
	while((dest[i] = source[index]))//while we've not reached the end of the string
	{
		if(source[index] != separator)//if the separator isn't reached yet
		{
			index++;//increment the variables
			i++;
		}
		else//on est rendu au sйparateur
		{
			index++;//we go to the next character (skip the separator)
			dest[i] = EOS;//in cas of troubles
			break;
		}
	}
}

have fun :P

use:

Код:

new input[] = "Hello, this is a testing!";
new begin = 5, destination[16];
strtok(input, begin, destination);
print(destination);

instead of:

Код:

new input[] = "Hello, this is a testing!";
new begin = 5, destination[16];
destination = strtok(input, begin);
print(destination);

note: this function is faster and safer, you don't need to worry about the length of an internal string, just care about yours.
edited function to make sure it is safe...

Re: Useful Functions - LarzI - 15.12.2009

And you're 100% sure that this code is working fully as the original strtok code?
If so, good job!

Re: Useful Functions - thegoliathmaster - 15.12.2009

Yes, i'm sure.

i've been using it for about 3 month now...
but the version i used had a little

Код:

dest[i] = EOS;

at the end to prevent problems with second use of a string, but after testing, the while loop is supposed to do it as-well (maybe not if your reach the separator, i'll check it)

Re: Useful Functions - Zeex - 15.12.2009

It may be even better if we will use static variable to hold the start of the next word:

pawn Код:

stock strtok(const source[], dest[], separator = ' ', start = -1)
{
    if (!source[0])
    {
        return 0;
    }
    new
        i,
        ch;
    static
        j;
    if (start == 0)
    {
        j = 0;
    }
    else if (start > 0)
    {
        j = start;
    }
    while ((ch = source[j++]))
    {
        if (ch != separator)
        {
            dest[i] = ch;
            i++;
        }
        else
        {
            while (source[++j] == separator) {}
            break;
        }
    }
    dest[i] = '\0';
    return i;
}

So we don't need to create a separate variable somewhere outside of function each time to store the index...

Re: Useful Functions - Zeex - 15.12.2009

What do you mean? Sorry I dont fully understand what you said (****** translator sucks).... But I still want to know. Could you give some code?

Re: Useful Functions - [HUN]Gamestar - 20.12.2009

Thank you,problem fixed.

No problem

[0.3]DisconnectNPC - [HUN]Gamestar - 20.12.2009

pawn Код:

stock DisconnectNPC(npcname[]) {
    new
        n[MAX_PLAYER_NAME],x=0;
    while(x!=GetMaxPlayers()) {
        GetPlayerName(x,n,sizeof n);
        if(!strcmp(n,npcname,true)) break;
        x++;
    }
    if(x==GetMaxPlayers())return INVALID_PLAYER_ID;
    Kick(x);
    return 1;
}

other job: usefull function in include.

First try code then post a message

I think there is no need to check the connection as it woudln't crash your server if the player isn't connected as it has built-in checking AFAIK.

Re: Useful Functions - Kyle - 20.12.2009

I made this one so you dont have to do

SetPlayerPos
As well as SetPlayerFacingAngle

pawn Код:

stock SetPlayerPosAndAngle(playerid,Float:x,Float:y,Float:z,Float:ang)
{
SetPlayerPos(playerid,x,y,z);
SetPlayerFacingAngle(playerid,ang);
}

{
  SetPlayerPos(playerid,Float:x,Float:y,Float:z);
  SetPlayerFacingAngle(playerid,Float:ang);
}

nice but you dont need to declare each time you use the variable as a floating number again if you did it at the definition
and you could try to make that function as an macro (#define balba) because that would make it faster

Re: Useful Functions - Kyle - 20.12.2009

Fixed it.

LOL! That's like

pawn Код:

stock GetPlayerID(playerid) return playerid;

xD xD xD
