You can use singleclick packethook.

but there is nothing about item color...could u show me some example of it?

Yessir.

You are right, I explained poorly.

We are using method where we first hook the singleclick and collect some data from object the player clicked. After that we send player a PrintTextAbovePrivate() with modified content. More optimal way would be creating and sending text packet instead of making core do it, but that's not part of this tuto.

Example of uopacket.cfg and singleclick.src below.

:singleclick:uopacket (.cfg)

Code: Select all

Packet 0x09
{
  Length            5
  ReceiveFunction	singleclick:singleclickhook
}

:singleclick:singleclick (.src)

Code: Select all

use uo;

program singleclick ( )
   print("Hooking singleclickpacket");
   return 1;
endprogram

exported function singleclickhook( who, byref packet )
    // Packet contains only the serial
    var object := SystemFindObjectBySerial(packet.GetInt32(1));
    
    if (object.isa(POLCLASS_ITEM))
        // So player clicked an item. Change text color to item's color.
        // Of course color can be anything, this is just an example.

        var color := object.color;
        
        PrintTextAbovePrivate(object, object.desc, who, _DEFAULT_TEXT_FONT, color);

        // --> player clicks green axe, he/she will get 'an axe' with green color.
        
        // Return 1 so core won't react.
        return 1;
    endif

    // If it was not an item, core will do.
    return 0;

endfunction

Code is mostly pseudo, but should give you the idea.

This sound like a different way to handle tooltips.
See the megacliloc packethook. Since it's in html format, you can change the colour of the text.

You can also change color displaying above things in the "send speech" packet. http://packets.polserver.com/index.php? ... acket=0x1C
