Trying to "shoot" bullets with gosu

Hi,

I have made a small 2d game with Gosu which has scores, collecting squares, a sprite and sounds. I want to now make my sprite "shoot" bullets.

Code: https://gist.github.com/2419934

Basically, when I press spacebar, it makes the sound that I have programmed into the initializer for Bullet, but doesn't draw the bullet. I'm not sure what I'm doing wrong here.

Thanks,

/J

You can't make drawing in Window.update. Maybe it was possible with older versions, but drawing code needs to be in Window.draw

@bullets.each do |bullet|
      bullet.update
      bullet.draw
end

This can be placed as it is in def draw in GameWindow

Ah, that gets the bullets drawn, but they aren't moving :(

def update
    accelerate_forwards
    move
end

This is how should Bullet.update look. They are only accelerating in your code

Ahh, thanks. :D

Now they fire, but really weirdly, and I can't fire them as often as I'd like.

Now you have to figure it yourself.

Aha! That worked great :D now I just need to implement bullets going different directions, which I will figure out myself :D

Thanks a lot lol_o2!
