Hello world

Let's code, compile and run your first program.

Prerequisites:

  • Install and run Rubik's Futuro Cube Suite, from now on, we mean: **RFCSuite **and connect CUBE via USB cable to PC.

  • If RFCSuite correctly communicates with the cube, the cube should turn black and the screen should look like this:

  • Now switch to View->SDK mode, you should see the SDK view and an available prompt given by Interactive shell

->

  • Just for fun type "colh 0x55124800" and hit enter - you should get the cube filled with the given color. For more information later, check Colors, palettes and drawing but for now let's get back to programming.
$>colh 0x55124800
r: 85(0x55), g: 18(0x12), b: 72(0x48), 0x55124800
__OK__
$>

Rubik’s Futuro Suite contains a standard PAWN compiler and allows you to compile scripts automatically with preset recommended stack and optimization settings (these can be adjusted by experienced user).

  • Create a directory, where you will create your first program and download there API definition file called "futurocube.inc". This is something like a header in C language and there is always a link on the SDK page to the latest version.

  • In you favorite text editor create a file called hello.p (p extension is necessary for RFCSuite to find this file). Simply copy, paste and save there the next few lines:

#include <futurocube>

main()
{
    SetColor(cORANGE)
    DrawSquare(GetCursor())
    PrintCanvas()
    printf("hello world\r\n")
}
