This function is meant to be used by DIALOG_STYLE_MSGBOX dialogs, when it is desired to show a large string, and this string to be split into several lines. It adds the line breaks just if it finds a ' ' (space) character.

- Parameters:
-- input[]: The string to be split.
-- chars[]: How many minimum characters should show per line (default: 80).
- Returns:
-- The formatted string.

pawn Code:

AddLineBreaks(input[], chars=80)
{
    new output[512];

    format(output, sizeof(output), "%s", input);

    for(new i, j, o = strlen(output); i < o; i++, j++)
    {
        if(j >= chars && output[i] == ' ')
        {
            output[i] = '\n';
            j = 0;
        }
    }

    return output;
}

Nice.

Try:

pawn Code:

stock
    AddLineBreaks(input[], chars = 80)
{
    new
        Count = 1,
        i = chars,
        output[512];
    format(output, sizeof(output), "%s", input);
    while(output[i])
    {
//      if(i % chars) { printf("Loop: %d", i); } else { printf("    Start chars Index: %d", i); } // DEBUG
        if(output[i] == ' ')
        {
            output[i] = '\n';
            i = chars * (++Count);
        } else i--;
    }
    return output;
}

pawn Code:

public
    OnFilterScriptInit()
{
    printf("%s", AddLineBreaks("This function is meant to be used by DIALOG_STYLE_MSGBOX dialogs, when it is desired to show a large string, and this string to be split into several lines. It adds the line breaks just if it finds a ' ' (space) character. - Parameters: -- input[]: The string to be split. -- chars[]: How many minimum characters should show per line (default: 80). - Returns: -- The formatted string"));


    printf("%s", AddLineBreaks("This function is meant to be used by DIALOG_STYLE_MSGBOX dialogs, when it is desired to show a large string, and this string to be split into several lines.

    return 1;
}

Output:
