Required Arguments

  • startX: An integer representing the absolute origin X position of the rectangle, represented by pixels on the screen.
  • startY: An integer representing the absolute origin Y position of the rectangle, represented by pixels on the screen.
  • width: An float representing the width of the rectangle, drawn in a right direction from the origin.
  • height: An float representing the height of the rectangle, drawn in a downwards direction from the origin.

Optional Arguments

Example of MOTD (message of the day), made using DxText, Line and Rectangle. 

local rootElement = getRootElement()
local x,y = guiGetScreenSize()  -- Get players resolution.
local playerName = getPlayerName ( getLocalPlayer() )  -- Get players name.
local MOTDText = "Welcome to our server, this is a test MOTD script for MTA's Wiki."  -- Example of MOTD message.


function create2DRectangle ( )
dxDrawRectangle ( x/2/2, y/2/2, x/2+40, y/2+40, tocolor ( 0, 0, 0, 150 ) )  -- Create our black MOTD background Rectangle.

dxDrawText( "Welcome " .. playerName, x/2/2+41, y/2/2+32, x, y, tocolor ( 0, 0, 0, 255 ), 1.01, "pricedown" )  -- Create Welcome title shadow.
dxDrawText( "Welcome " .. playerName, x/2/2+40, y/2/2+30, x, y, tocolor ( 255, 255, 255, 255 ), 1, "pricedown" )  -- Create Welcome title.
dxDrawLine ( x/2/2+20, y/2/2+57, x/2/2+y/2+332, y/2/2+57, tocolor ( 0, 0, 0, 255 ), 3 )  -- Create underline shadow for title.
dxDrawLine ( x/2/2+20, y/2/2+55, x/2/2+y/2+330, y/2/2+55, tocolor ( 255, 255, 255, 255 ), 2 )  -- Create underline for title.
dxDrawText( MOTDText, x/2/2+40, y/2/2+80, x, y, tocolor ( 255, 255, 255, 255 ), 1, "clear" )  -- Create MOTD text.
end


function HandleTheRendering()
addEventHandler("onClientRender",rootElement, create2DRectangle)  -- Keep everything visible with onClientRender.
end
addEventHandler("onClientResourceStart",rootElement, HandleTheRendering)
