To do a simple program that displays "Hello world" on a black screen, here is the code:
require "vx" function autoexec() local text = "Hello World" while true do vx.screen:RectFill(0, 0, vx.screen.width, vx.screen.height, vx.RGB(0, 0, 0)) vx.default_font:Print(vx.screen.width / 2 - vx.default_font:TextWidth(text) / 2, vx.screen.height / 2, text) vx.ShowPage() end end
