Fill in IDs, generate, and there you go:

pawn Код:

stock IsValidAirVehicle(value) {
    static const valid_values[6] = {
        1073742081, 135268352, -1073676096, 192, 262408, 98305
    };

    if (417 <= value <= 593) {
        value -= 417;


        return (valid_values[value >>> 5] & (1 << (value & 31))) || false;
    }

    return false;
}

Awesome!

The generator is very nice!
Anyway can you give some info how it works? (How generate and how you read this information)

I tried to do it myself without generator, but I don't know read the values without cycle.

I tried to do it myself without generator, but I don't know read the values without cycle.

First it sorts the values and gets the lowest and highest values
Than it creates a list of bits from the lowest till the highest value (cells = ((max - min) / 32))
At last it sets the bits at the correct positions (value1 - min; value2 - min; ...)

pawn Код:

stock func(value) {
    static const valid_values[] = {
        // values
    };

    if (min <= value <= max) {
        value -= min;

        // it gets the correct cell with "valid_values[value >>> 5]" or "valid_values[value / 32]"
        // with "value & 31" it extracts the position, similar to "value % 32"
        // 1 << position, is just 2 ^ position (Exponentiation)
        // the & just checks now if the bit is set in the cell
        return (valid_values[value >>> 5] & (1 << (value & 31))) || false;
    }
    return false;
}

You can use foreach. I do use foreach myself, but perhaps someone might find useful to keep track of joins.

That's what foreach does too.

Are you sure about that? To my knowledge, it doesn't. However, I haven't looked foreach code in depth.

Re: Useful Snippets - kacper55331 - 21.08.2012

pawn Code:

#define formatex(%1,%2,%3,%4) new %1[%2];format(%1, %2, %3, %4)

Usage:

pawn Code:

formatex(string, 20, "My awasome ID: %d", playerid);
SendClientMessage(playerid, 0, string);

I guess this is a better way.

You can also use the ternary operator:

pawn Code:

CMD:bugreport(playerid, params[])
{
    if(IsNull(params))
    {
        SendClientMessage(playerid, -1, "USAGE: /bugreport [bug information]");
        return 1;
    }

    new
        File:Bugs;

    Bugs = fopen( "bugs.txt", ( fexist("bugs.txt") ? io_append : io_write ) );
    fwrite(Bugs, params);
    fclose(Bugs);
    SendClientMessage(playerid, -1, "Your bug has been submitted successfully! Thank you for your feedback.");
    return 1;

}

Re: Useful Snippets - Slice - 17.09.2012

First off, that won't work because "rstring" isn't an array. Secondly, you don't need to use format because, well, you're not doing any formatting.

Re: Useful Snippets - Glint - 17.09.2012

It will be something like this :

pawn Код:

public OnPlayerUpdate(playerid)
{
    if(GetPlayerWeaponState(playerid) == 3)
    {
        SetPlayerChatBubble(playerid, "RELOADING", 0x660000AA, 150.0, 2500);
    }
    return 1;
}

Show player damage (hit counter as you shoot them) in chat bubble above victim

Top of script:

Код:

new string[16];

Then:

Код:

public OnPlayerTakeDamage(playerid, issuerid, Float: amount, weaponid)
{
    format(string,sizeof(string),"-%.0f hp",amount);
    SetPlayerChatBubble(playerid,string,0x660000AA,150.0,2500);
    return 1;
}

This will display how much health/armor the player lost when hit in a chat bubble above the player's head (for 2.5 seconds).

Note: this is a good way to spot cheaters, because I've noticed people using health/armor hacks do NOT call OnPlayerTakeDamage...so if you shoot a player and never see the chat bubble, they are likely cheating. Food for thought.

@kaisersouse string can be easly a local variable....

This is probably the best way, considering that most people use "string" for a general string name.
