@PhillipS You made my day LMAO. Thanks for making me laughing as hell...

ContainInvalidCharacters
I created this function on any time ago... Good to check and create "normal" passwords and to set player name.

Check if have invalid characters in one string.

pawn Код:

#define function%0(%1) stock %0(%1)

function ContainInvalidCharacters(string[])
{
    // Add more if you need/want. (if you add new characters, you should add the quantity of characters that you put to the variable. ("19"))
    new InvalidCharacters[19][] =
    {
        "&","$","^","?","_",".","*","#","(",")",
        "[","]","{","}","=","+","-","!","@"     
    };
    
    for(new checkloop; checkloop<sizeof(InvalidCharacters); checkloop++)
    {
        if(strfind(string, InvalidCharacters[checkloop]) != -1) return true;
    }
    
    return false;
}

An example :

pawn Код:

public OnGameModeInit()
{
    new varstring[15] = "mystringwith@";
    if(ContainInvalidCharacters(varstring)) return print("- 'varstring' contains invalid characters !");
    
    return 1;
}

Output :

[04:42:32] - 'varstring' contains invalid characters !

Enjoy and i hope it is useful !

Re: Useful Functions - RyDeR` - 29.12.2012

You don't need an array for that. I guess you're just looking for numbers and alphabetic characters:

pawn Код:

stock isValidPassword(const szPass[]) {
    for(new i = 0; szPass[i] != EOS; ++i) {
        switch(szPass[i]) {
            case '0'..'9', 'A'..'Z', 'a'..'z':
                continue;
            default:
                return 0;
        }
    }
    return 1;
}

AW: Useful Functions - IPrototypeI - 02.01.2013

PHP код:



stock MoveCameraInCircelRotation(playerid,Float:winkel2, Float:x_koordinate, Float:y_koordinate, Float:z_koordinate, Float:radius1, Float:winkel)

{

    PlayerCamInfo[playerid][player_degree1] =(winkel2 > 360)?(0):((winkel < 0)?(360):(PlayerCamInfo[playerid][player_degree1]));

    PlayerCamInfo[playerid][player_degree2] =(winkel > 360)?(0):((winkel < 0)?(360):(PlayerCamInfo[playerid][player_degree2]));

    SetPlayerCameraLookAt(playerid,x_koordinate,y_koordinate,z_koordinate);

    x_koordinate += (radius1 * floatcos(winkel, degrees) * floatcos(winkel2, degrees));

    y_koordinate += (radius1 * floatcos(winkel, degrees) * floatsin(winkel2, degrees));

    z_koordinate += (radius1 * floatsin(winkel, degrees));

    SetPlayerCameraPos(playerid,x_koordinate,y_koordinate,z_koordinate);

    return 1;

}

with this calculation you get the koordination from a globe to rotate you camera around it
but you have to chance some variabel for example PlayerCamInfo[playerid][player_degree2]

AW: Useful Functions - IPrototypeI - 02.01.2013

PHP код:



stock SetPlayerFacingAngleToPoint(playerid,Float:X, Float:Y){

   new Float: Pos[2];

   GetPlayerPos(playerid, Pos[0], Pos[1], 0);

   return SetPlayerFacingAngle(playerid,180.0-atan2(Pos[0]-X,Pos[1]-Y));

}

This code set your FacingAnglethe the direction of a point it can be useful to rotate a bot(using RNPC) that he can shot at you.

This makes it easier:

pawn Код:

stock 
    Float:absoluteangle2(Float:angle)
{
    while(angle < 0.0) angle += 360.0
    while(angle > 360.0) angle -= 360.0;
    return angle;
}

AW: Useful Functions - IPrototypeI - 02.01.2013

PHP код:



stock GetAge(string[])

{

       new var0, var1, var2, Date[3], age;

       sscanf(string, "p<.>iii", var0, var1, var2);

    if(var0 > 31 || var0 <= 0)return 0;

    if(var1 > 12 || var1 <= 0)return 0;

    getdate(Date[0],Date[1],Date[2]);

    if(var2 > Date[0] || var2 < 1900)return 0;

       age = Date[0] - var2 - ((Date[1] < var1)? 1 : ((Date[1] == var1 && Date[2] < var0)? 1 : 0));

       return age;

}

with this code it is possibel to calculate the age with a date as a string

Re: Useful Functions - Sasino97 - 06.01.2013

Today I was looking at the PAWN example scripts (downloaded from CompuPhase's website some time ago) and I noticed a function that can be useful also in SA-MP. So I decided to edit it to make it avaiable in PAWN 3.0 and to paste it here

pawn Код:

rot13(string[])
{
    for(new index = 0; string[index]; index ++)
    {
        if ('a' <= string[index] <= 'z')
            string[index] = (string[index] - 'a' + 13) % 26 + 'a';
        else if ('A' <= string[index] <= 'Z')
            string[index] = (string[index] - 'A' + 13) % 26 + 'A';
    }
    return 0;
}
// By CompuPhase

That function will mangle the string you enter.

The original was this

pawn Код:

rot13(string[])
    {
    for (new index = 0; string[index]; index++)
        if ('a' <= string[index] <= 'z')
            string[index] = (string[index] - 'a' + 13) % 26 + 'a'
        else if ('A' <= string[index] <= 'Z')
            string[index] = (string[index] - 'A' + 13) % 26 + 'A'
    }

but it will work only in pawn 4, and SA-MP uses pawn 3.

Respuesta: Useful Functions - [DOG]irinel1996 - 08.01.2013

Someone suggested this for SA-MP 0.3x, so I tried to make it:

pawn Код:

stock GetVehiclePlayerInSeat(vehicleid, seatid) {
    if (!GetVehicleModel(vehicleid)) return INVALID_VEHICLE_ID;
    new
        total = GetMaxPlayers()
    ;
    for (new x; x < total; x++) {
        if (IsPlayerConnected(x)) {
            if (IsPlayerInAnyVehicle(x) && GetPlayerVehicleSeat(x) == seatid) {
                return x; //Thanks ****** for making me notice this. (player id 0 issue)
                break;
            }
        }
    }
    return INVALID_PLAYER_ID; //Thanks Slice
}

Returns:
x -> player's id who is seated on the seatid.
INVALID_VEHICLE_ID -> the vehicle doesn't exist.
INVALID_PLAYER_ID -> the seatid is empty.

PD: I didn't test it, but I guess it should work.

Best regards!

EDIT: Tested.

To be honest, I can't see the error, when x is declared its value should be 0, or not?

EDIT: Ohh, I'm so stup*d, I just saw that.

PD: I'm going to test it right now.

If it were player 0 in that seat, it would return 0, saying that the seat is actually empty.

Your signature is also very immature.

Yes, after ****** answer I saw that, I didn't think about it.

PD: unfortunately, there are many important things that are more immature than my signature. As they say, YOLO.

Re: Useful Functions - Slice - 08.01.2013

Use INVALID_PLAYER_ID, not -1. Please.

I guess so.
Maybe, different conditions with other messages, as scripter wants. (?)

AW: Useful Functions - IPrototypeI - 09.01.2013

with SecToMin you can convert seconds to minutes
for example

119 secounds are 1:59 minutes

PHP код:



stock SecToMin(sec) {

    return printf("%02d:%02d", (sec/60), sec % 60);

}

and with this code you can convert milliseconds to minutes
example:
182412 ms are 3:02:412 minutes

PHP код:



stock MsToMin (sec) {

    return printf("%02d:%02d:%02d", ((sec / (1000*60)) % 60), (sec / 1000) % 60,sec %1000);

}

    }

}

Best regards!

EDIT: Tested.

That's going to give a warning. You can't have the break keyword under the return keyword, so you'll have to remove the break;

Oh okay, thanks for the info. Appreciate it.

Re: Useful Functions - DarkPower - 20.01.2013

For RP servers

pawn Код:

stock getName(playerid)
{
    new sNick_[MAX_PLAYER_NAME];
    GetPlayerName(playerid, sNick_, MAX_PLAYER_NAME);
    for(new iX__ = (0); iX__ < strlen(sNick_); ++ iX__) if(sNick_[iX__] == '_') sNick_[iX__] = (32);
    return format(sNick_, MAX_PLAYER_NAME, "%s", sNick_), (sNick_);
}

Example, lets say that my nick is Andrew_Kramer:

pawn Код:

new string[64];
format(string, (sizeof string), "My name is: %s", getName(playerid));
SendClientMessage(playerid, -1, string);

Server will print My name is: Andrew Kramer

Re: Useful Functions - TheArcher - 20.01.2013

@DarkPower Why "_" after the variables? E.g "new sNick_" or "new iX__" makes no sense.

Re: Useful Functions - Emmet_ - 20.01.2013

@DarkPower: You shouldn't use strlen in a loop. And the format wasn't necessary.

pawn Код:

stock getName(playerid)
{
    new pos = -1, name[MAX_PLAYER_NAME];
    GetPlayerName(playerid, name, sizeof(name));
    while ((pos = strfind(name, "_", true)) != -1)
    {
        name[pos] = ' ';
    }
    return name;
}
