Today, I learnt that
This Current Code, can be used in opposite ways (I don't know how it is called, but I'll call it, Opposite Function :P)

pawn Код:

new 
    PlayerTeam [ MAX_PLAYERS char ]
;

//Normal Function
if(PlayerTeam{playerid} == 1)
{
    Rest Of The Code In Here
}

//Opposite Function
if(1 == PlayerTeam{playerid}) 
{
    Rest Of The Code In Here
}

Today I learned that MySQL strict mode requires you update all fields in a query, or have a default values in place for the fields you aren't updating. Otherwise...anger occurs.

Thanks KingJ!

They're called Yoda conditions!

Highly encouraged in languages without "possible unintended assignment" warnings

TIL that having spaces before and after a color code in a textdraw can seriously mess up your server and even crash it! Is it a fact or just me?

Also, TIL that the C++ taught in college is seriously outdated, modern C++ is like a new language itself, I got lost in a matter of seconds! (Vectors, STL, containers, etc?) No modest documentation, only big big words.

Today i learned how to detect a word from a single character for example...

If Player Abuses using the world "fuck". Then Using A "for" loop we can loop through the string lenght of players text and detect if theres a word 'f' and if yes detect if the words position + 1 is 'u' again check if position of f + 2 is 'u' and position of word + 3 is 'k' using LOGICAL AND..

Like

pawn Код:

public OnPlayerText(playerid,text[])
{
     for(new i = 0; i <= strlen(text); i++)
     {
           if(text[i] == 'f' && text[i+1] == 'u' && text[i+2] == 'c' && text[i+3] == 'k') // Do Something
     }
     return 1;
}

Well this is the longest way to detect a abusive word in players text but might be usefull to detect correct abusive words in the chat

Well I learned how to create a custom 3DTextLabel with dynamic colours and a customised name through a dialog-based system using inputtext and custom colors.

Today i learned About Enums and isnull, isnull is used to check if is nothing params of a cmd or to check whether smthing is typed. Enum are used to store hugr amount of data.

with this code

pawn Код:

if( isnull (params) ) // for ISNULL
/* ---------------------------------------------------- */
enum whattolearn
{
    english,
    pawnlanguage,
    martianlanguage,
    badlanguage
};
new lang [] [whattolearn]
/* don't try my ENUM example :P */

isnull is used to check for empty strings.

NO. variables store data. the 'new' keyword creates a variable. enums define a list of symbolic constants.

ok... did anyone learn anything useful today?

i learn that there is a lot to be learned about pawn and scripting in general

Re: Today I learned - Share your newly found knowledge! - Albright - 03.11.2013

Today, I learned about string formatting, local & global variables and a bit of stocks.

AW: Today I learned - Share your newly found knowledge! - IPrototypeI - 03.11.2013

Today i learned how to create a map location mover and to rotate to hole map

wtf^? u just attach all objects? and what is the point of this

Re: Today I learned - Share your newly found knowledge! - Pottus - 05.11.2013

Not bad, next step customize your rotation node

I learned how to use SetTimer properly. (but still have a mistake)

pawn Код:

forward ResetRob(playerid);

        GetPlayerPos(targetid, X, Y, Z);
        GetPlayerName(targetid, targetname, sizeof(targetname));
        GetPlayerName(playerid, playername, sizeof(playername));
        if(IsPlayerInRangeOfPoint(targetid, 4, X,Y,Z))
        {
            if(GetPlayerMoney(targetid) <= 2500 || RecentRobbed[targetid] == 1 || RecentRob[playerid] == 1)
            {
                SendClientMessage(playerid, -1, "{ff0000}=ERROR=: {ffffff}You can't rob this player as the player's cash is less than $2500 or he's recently robbed!");
                return 0;
            }
            else if(GetPlayerMoney(targetid) > 2500 && RecentRobbed[targetid] == 0 || RecentRob[playerid] == 0)
            {
                new string[128];
                new Money = GetPlayerMoney(targetid);
                new Robbed = random(Money);
                GivePlayerMoney(playerid, Robbed);
                GivePlayerMoney(targetid, -Robbed);
                format(string, sizeof(string), "{ffff00}=SUCCESS=: {ffffff}You have robbed %d from %s!", Robbed, targetname);
                SendClientMessage(playerid, -1, string);
                format(string, sizeof(string), "{ffff00}=SUCCESS=: {ffffff}%s has robbed %d from you!", playername, Robbed);
                SendClientMessage(targetid, -1, string);
                RecentRobbed[targetid] = 1;
                RecentRob[playerid] = 1;
                UserInfo[playerid][uRobbed]++;
                SetTimer("ResetRob", 5*60*1000, 0);
                return 1;
            }
        }
    }
    return 1;
}

Just sayin'. Take this script if you want my shitty script.

    return 1;

Just sayin'. Take this script if you want my shitty script.

Instead of creating timer for each function make a global one, which contains everything.

The point of this was not how to rotate the Objects, but rather to save all coords of this Objects.

Just sayin'. Take this script if you want my shitty script.

It's not this:

pawn Code:

SetTimer("ResetRob", 5*60*1000, 0);

It's this:

pawn Code:

SetTimerEx("ResetRob", 5*60*1000, false, "i", playerid);

SetTimerEx will forward it if it has any variables within the brackets, forgot how to phrase this.

pawn Code:

forward ResetRob(); // this would use SetTimer
forward ResetRob(playerid); // this would use SetTimerEx
