Today I want to announce a new release of DJson. The 1.6 is now using a different method to create the cache-file, which allows running multiple djson-scripts (like filterscripts) at the same time.

Also it features a method to define own DJSONMAXSTRING (before include of djson), if you need really big content.

Head over to the official

DJson page or directly to the djson 1.6 download.

When creating new REST-ful API for GTAT (based upon my pwncurl and a lua backend) I had to implement the method urlencode in pawn.

So I took a look at the specification in RFC 1738 to get information about what characters need to be encoded.

Since I really want to be sure that all is encoded properly and %xx encoding is

<!--more-->allowed, too - even if not neceassary - my urlencode function encodes every character except A-Z,a-z,0-9,'-','_' and '.'.

/**
 *  Url encodes a specific string
 *  @param string string
 */
stock urlencode(string[]) {
    new ret[MAX_STRING];
    ret[0] = 0;
    new i = 0;
    new p = 0;
    new s = 0;
    while (string[i] != 0) {
        if  (
                (string[i] >= 'A' && string[i] <='Z')
                || (string[i] >= 'a' && string[i] <='z')
                || (string[i] >= '0' && string[i] <='9')
                || (string[i] == '-')
                || (string[i] == '_')
                || (string[i] == '.')
            ) {
                ret[p] = string[i];
            } else {
                //
                ret[p] = '%';
                p++;
                s = (string[i] % 16); //
                ret[p+1] = (s>9) ? (55+s) : (48+s); // 64 - 9 = 55
                s = floatround((string[i] - s)/16);
                ret[p] = (s>9) ? (55+s) : (48+s); // 64 - 9 = 55
                p++;
            }
        p++;
        i++;
    }
    return ret;
}

This function will also be part of next release of dutils.

If you try to set the CSS-property

background-position in Internet Explorer (I tested with 7) and even use that with Mootools' morph/tween-functions, it will not work.

You can workaround that issue, if you set also background-position-x and background-position-y (actually ignored by my Firefox 3.0).

This is the code, I use at koala to move the background upwards.

$('body').morph({
    'background-position':'0 -140px',
    'background-position-y':'-140px',
});

If you are using pawn (for instance in san andreas multiplayer) and want to rename a file, you'll not find a method like frename.

You can either use my

dutils (pawn only solution) or a plugin (like Yless' YSF) to add frename to your functions.

If you want to make a plain pawn solution, and don't want to use dutils, here is how I made it.

There are two steps.

First you'll need fcopy (copies the file):

ohnd=fopen(oldname,io_read);
nhnd=fopen(newname,io_write);
new buf2[1];
new i;
for (i=flength(ohnd);i>0;i--) {
    fputchar(nhnd, fgetchar(ohnd, buf2[0],false),false);
}
fclose(ohnd);
fclose(nhnd);

And then you'll need to remove the old file.

fremove(oldname);

Remember, that on linux those methods will not work (since fputchar is bugged on linux). You need to use the pawnonly frenametextfile and fcopytextfile from

dutils for that.

If you want to hide a specific player on the map, you can set the alpha value to 0x00. If you want to make him visible again, you just have to set it to 0xFF.

Since this is not always simple, to store the current color of the player in a invisible and a visible way, you can use bitwise or to do that task for you.

This is my togglePlayerMapIconVisibility function, which keeps the color of the player and toggles the player to visible or invisible on the map.

stock togglePlayerMapIconVisibility(playerid,bool:visible){
    SetPlayerColor(playerid, (GetPlayerColor(playerid) | 0xFF) - (visible ? 0x00 : 0xFF));
}
