GameBoy Dev02: Moving Sprites

It is recommended to read the previous articles to better understand this one:

In this article, we will reuse the sprite from the previous article but we will move it around the screen using the movement arrows.

vi 02.c

#include <gb/gb.h>
#include <stdio.h>
#include "Carita.c"

void main(){
    set_sprite_data(0, 2, Carita);
    set_sprite_tile(0, 0);
    move_sprite(0, 88, 78);
    SHOW_SPRITES;

    while(1){
        switch(joypad()){
            case J_LEFT: 
                scroll_sprite(0,-2,0);
                break;
            case J_RIGHT: 
                scroll_sprite(0,2,0);
                break;  
            case J_UP: 
                scroll_sprite(0,0,-2);
                break; 
            case J_DOWN: 
                scroll_sprite(0,0,2);
                break;                                                   
        }
        delay(100);
    }
}

We compile the game and load it into the emulator:
