Add line @ 706 in scoreboard:
elseif column.name == "ping" then
local ping = tonumber ( content )
local r, g
if ping < 150 then
r = 255
g = ( ping / 150 ) * 255
else
r = ( ( 300 - ping ) / 150 ) * 255
g = 255
end
dxDrawText( content, topX+theX+s(1), y+s(1), topX+x+s(1+column.width), y+s(11)+dxGetFontHeight( fontscale(contentFont, scoreboardScale), contentFont ), tocolor( 0, 0, 0, a or 255 ), fontscale(contentFont, s(1)), contentFont, "left", "top", true, false, drawOverGUI )
dxDrawText( content, topX+theX, y, topX+x+s(column.width), y+dxGetFontHeight( fontscale(contentFont, scoreboardScale), contentFont ), tocolor( g, r, 0, a or 255 ), fontscale(contentFont, s(1)), contentFont, "left", "top", true, false, drawOverGUI )
So I made it by myself toady.
