Gameboy Development Forum

Hi!
I'm kind of new to GBDK programming and I was wondering how to detect gameboy input, when I want to check if 2 buttons are pressed at once?
Let's say I want to do a platformer and be able to go right and jump at the same time - how to do it?

I made a simple program that prints joypad() output in a while(1) - it doesn't make much sense to human, but what I found out is that there are different outputs if you press just A, just B, and both at once.

I came up with something like this, but I'm not sure if it's the right way:

if(joypad() == J_RIGHT) {
  for(i=0; i<=5; i=i+1) {
    move_player_right();
    if(joypad() == J_A) {
      jump();
    }
    delay(20);
  }
}

I didn't really test it yet, it's just an idea.

Some help, please?
