Habit, _ in variable's name is the same as every other 'normal' character.

@Emmet_ - I totally forgot to use strfind -.- and why is strlen bad in loop?

And this way?

pawn Код:

stock getName(playerid)
{
     new pName[MAX_PLAYER_NAME], ch = (0);
     GetPlayerName(playerid, pName, MAX_PLAYER_NAME);
     ch = strfind(pName, "_");
     if(ch != -1) pName[ch] = (32);
     return (pName);
}

Re: Useful Functions - DarkPower - 20.01.2013

So, this is a good way:

pawn Код:

for(new i = (0), size = strlen(playerName); i < size; ++ i)

That is same as:

pawn Код:

new size = strlen(playerName);
for(new i = (0); i < size; ++ i)

It must be out from condition
I understand now, thanks Southclaw

Indeed is what I'm saying...You don't have to show a code as "hard" if it's not... lol

That is not a reason why i put "_" i know that it is not necessary in this case but as i say, habit

What the hell kind of habit is that?

I also don't see how they're the same as alpha-numeric characters - any person that isn't blind will tell you they're different.

Where can I get Functions Or Filterscript,, AUTO PARK

I mean it, "if we get out of the car or we logout of the server, my car was in last place out of.

Re: Useful Functions - Kirollos - 03.02.2013

I've made small code requested by a friend so i said if i can write it here

( PS: i cba to check in all these pages if its already there o.o )

pawn Код:

stock IsDateBetween(day1, month1, year1, day2, month2, year2)
{
    new day, month, year;
    getdate(year, month, day);
    
    if((year1 == year2) && (year1 == year))
    {
        if((month1 == month2) && (month1 == month))
        {
            if((day1 < day) && (day2 > day)) return 1;
        }
        else
        if((month1 < month) && (month1 > month)) return 1;
    }
    else
    if((year1 < year) && (year2 > year)) return 1;
    return 0;
}

it checks if the current date is between 2 specified dates.

Usage:

pawn Код:

IsDateBetween(day1, month1, year1, day2, month2, year2);

Example of using

pawn Код:

public OnFilterScriptInit()
{
    printf("IsDateBetween 02/02/2013 and 08/02/2013 returned: %i", IsDateBetween(2, 2, 2013, 8, 2, 2013));
    // as we are in 04/02/2013 now (for me) it will return 1 . after/before the specified date, it will return 0
    return 1;
}

Re: Useful Functions - SuperViper - 11.02.2013

pawn Код:

timeFromSeconds(seconds, &returnedMinutes, &returnedSeconds)
{
    returnedMinutes = floatround(seconds / 60, floatround_floor);
    returnedSeconds = seconds - (returnedMinutes * 60);
}

Usage:

pawn Код:

new minutes, seconds;
timeFromSeconds(342, minutes, seconds);

Minutes will be 5 and seconds will be 42.

Usage:

pawn Код:

new minutes, seconds;
timeFromSeconds(342, minutes, seconds);

Minutes will be 5 and seconds will be 42.

This:

pawn Код:

returnedMinutes = floatround(seconds / 60, floatround_floor);

is the same as:
First dividing the numbers normally as integers, then converting the result to a float!

pawn Код:

returnedMinutes = floatround(float(seconds / 60), floatround_floor);

which is the same as:

pawn Код:

returnedMinutes = seconds / 60;

Integer divisions always truncate the decimals (basically just removes them, which is what floatround_floor does to numbers > 0).

pawn Код:

stock DeductPlayerDamage(playerid, Float:damage, Float:multiplier=1.0)
{
    //WeaponDamage[playerid] = damage * multiplier; You may want to add this if you have a SetPlayerArmourEx anticheat, it's highly recommended and add offsets for the damage.
    new
        Float:health,
        Float:armour;
    GetPlayerHealth(playerid, health);
    GetPlayerArmour(playerid, armour);
    if (armour > 0)
    {
        if (armour - (damage * multiplier) <= 0) {
            SetPlayerArmourEx(playerid, 0);
            if (health - floatabs(armour - (damage * multiplier)) <= 0)
            {
                SetPlayerHealth(playerid, 0);
                return true;
            }
            else
            {
                SetPlayerHealth(playerid, health - floatabs(armour - (damage * multiplier)));
            }
        } else {
            SetPlayerArmourEx(playerid, armour - (damage * multiplier));
        }
    }
    else
    {
        if (health - (damage * multiplier) <= 0) {
            SetPlayerHealth(playerid, 0);
            return true;
        } else {
            SetPlayerHealth(playerid, health - (damage * multiplier));
        }
    }
    return false;//the result doesnt make the target die
}

I created this function, you can enter 200 as the damage and it will damage the player starting from their armor (if they have any) to their health. This supports even health and armour above 100, it will not matter and you can use this for weapon damage boosting. I could not any function similar to this on the forum, thank god I had known of how to use the mathematical function absolute value.

Re: Useful Functions - TheArcher - 13.02.2013

Where " SetPlayerArmourEx " comes from?

    new Float:pos[5];
    GetPlayerPos(playerid, pos[0], pos[1], pos[2]);

    GetPlayerPos(playerid, pos[3], pos[4], Z);

Example

pawn Код:

CMD:a(playerid, params[])
