AlliedModders - RGB, RGBA, Hex

Some shitty tutorial. (Copy most text from wiki)

There have been this new chat color feature in few source games for a while,
let's look how we could "make" these color values.

Custom chat color use a hex triplet (three-byte hexadecimal number), where bytes represent the red, green and blue components of the color (RGB).
In hexadecimal FFFFFF.
Where one color channel range is in hex 00 - FF, in decimal 0 - 255

"Note that if any one of the three color values is less than 16 (decimal) or 10 (hex), it must be represented with a leading zero so that the triplet always has exactly six digits."
For example, wrong way (%X)

PHP Code:


		
			
PrintToChatAll("%X%X%X", 4, 8, 16); // Show RGB decimal-triplet in hex, would be 4810

Same example but with advanced formatting (%02X)

%: always required
flag 0: Pads with 0s instead of spaces when needed
width 2: Minimum number of characters to be printed. If the value to be printed is shorter than this number, the result is padded with blank spaces. The value is not truncated even if the result is larger.
precision : skipped
specifier X: Hexadecimal representation of the binary value

PHP Code:


		
			
PrintToChatAll("%02X%02X%02X", 4, 8, 16); // Show RGB decimal-triplet in hex, would be 040810

Ok, we have get hex-triplet output with three separate decimal places.
But this can be more easier. (Found from google, but seems bl4nk have also posted before)
This how combine all three color channels to one. (RGB to Hex)

PHP Code:


		
			
    new my_color;

    my_color |=    ( (5   & 0xFF) << 16);        // Red    05----

    my_color |=    ( (200 & 0xFF) << 8 );        // Green  --C8--

    my_color |=    ( (255 & 0xFF) << 0 );        // Blue   ----FF



    PrintToChatAll("%06X", my_color); // Output will be 05C8FF

Explain to me

These above (RGB) now works with chat color character "\x07" https://dl.dropbox.com/u/38118182/pi...color_text.png

PHP Code:


		
			
PrintToChatAll("\x07%06XMy color", my_color);

-------------

Another chat color character "\x08", require four color channel (RGBA) where last channel is Alpha, modify text opacity/transparency.
Almost same way as above but we add one more hex byte = two hex digits.
And now remember also that formating, 8 hex digit (%08X)

PHP Code:


		
			
    new my_color;

    my_color |=    ( (5   & 255) << 24);        // Red    05------

    my_color |=    ( (200 & 255) << 16);        // Green  --C8----

    my_color |=    ( (255 & 255) << 8 );        // Blue   ----FF--

    my_color |=    ( (50  & 255) << 0 );        // Alpha  ------32



    PrintToChatAll("%08X", my_color);    // 05C8FF32

Example with RGBA https://dl.dropbox.com/u/38118182/pi...text_alpha.png

PHP Code:


		
			
PrintToChatAll("\x08%08XMy color", my_color);

------

Yes, can do even more simple than those before. Just add straight Hex color value in output text, or use text.

PHP Code:


		
			
PrintToChatAll("\07%sRed \x0800FF00A0Green \x07%06XBlue",        "FF0000", 0x0000FF);

We can do also this in translation files, not need edit plugin :3
I attached test translation phrase, hope those characters not get erased after uploading here.

Sry for bad english and lot of text with misspellings, typos, wrong info.
