Space Invadors

I'm improving the space invaders clone that came with F4NS. I still need to add the 2 other aliens and the UFO. Also need to add player score, lives and endless play.

Yessss! Excellent stuff mate!

They look much more like real invaders :) I decided to stay with very different invaders for obvious reasons. This is a BIG improvement!

I've actually been working on a 3D version of Space Invaders which I'm sure you'll see on here at some point!

That's great!

here's what I'd do to it (if I had the skill)
1: slow down the firing rate, its too fast (also don't forget you can only have one bullet on screen at any time)
2: add bases for the player to hide behind (or shoot through, like we used to)
3: add the bonus ship along the top

I guess you won't be able to add the nerve wracking "thump thump thump" sound effect, but still it's looking great, please keep at it!

I dunno, all the pacman sounds in my game are generated through changing frequency and volume 60 times per second, so I wouldn't be surprised if that could be achieved!

I believe the original "thump thump" was just short saw waveforms at a low frequency. The similar effect can be achieved easily without using any modulator or things like that. IMO, this sounds pretty similar to the original:

freqs = [48.9, 46.2, 61.7, 55.0]

i = 0
fpscount = 0
volume = 0.60

loop
   if (fpscount % 40) == 0 then
     playNote(0, 2, freqs[i % 4], volume, 20, 0.50)
     i += 1
   endif
   fpscount += 1
   update()
repeat

To gradually increase the speed of the "thump thump", you just have to gradually decrease the "40" value in "fpscount % 40"

@SteveZX81 Yes I was already thinking about adding that stuff. Very good ideas tho. I did change the players "ship" to match the original already.

@Nisse5 I'll have to try that out when I have time. Thanks. I think we are taking my daughter to the zoo shortly so it will probably be in a few hours.

There it is with the added game sound.

Not much added today. Was kind of busy but here's an update.
