Pacman in Axe
« on: October 18, 2010, 06:39:14 pm »
So, a while ago I was on ticalc.org, and I downloaded this file.  I was impressed by the game, but there were some parts of it that I didn't like.  I said to myself, "you should use Axe to make an awesome version of this."  So I got started.  The only thing left to do is add a control system for the ghosts.

I have to say my favorite part is wrapping from one side to the other.



Well, that's what I have been up to recently.

The source and executable can be found here:

If anyone is interested in making levels, I can edit in some more information on that.

Nice. :)  The funny thing, is that program was written by Quigibo, the author of Axe. :P
Good luck on it. :)

Uh-oh, shh!

But seriously.  I didn't even notice that.

Nice. What about a direct port?

By port, do you mean adapting the original Pac-Man game's code to axe?

I can't make them exactly the same because of the screen size.  Plus I don't want to make this scroll.

Nope, it's pure ASM.

And wow, that was made by Quigibo? I never realized, even though I played it two years ago...

Wow awesome! It looks very great! I also remember an older port released in 1999-2000 but it had scrolling.

Here is an update on my progress, for anyone interested.

Completed:
  • Added support for multiple levels
  • Changed format of level data for maximum compression
  • Made two more levels
  • Fixed a bug with the warp tunnel
  • Fixed a bug with losing lifes after winning a level
  • Fixed some major issues with collision testing
  • Set up an appvar
  • Made making levels much easier through a BASIC program (uses Omnicalc)

To do:
  • Add a control system for the ghosts.
  • Create a game over screen
  • Add high score saving

Things I am considering doing:
  • Make turning easier
  • Display score during gameplay
  • Make main menu nicer looking (perhaps even with grayscale?)

Here is a (really long) screenie showing me eating lots of dots in the new levels.  Near the end I mess with the new, more lenient collision testing.


EDIT:
Attached prog, source and level creation program.

ooh, this looks very nice. (especially the warp wrap-around) i haven't tried it out, but if turning is difficult it should register if a directional key is pressed and then wait until either the character can turn in the designated direction or until another key is pressed before the player has to do anything else. gray all throughout would also look nice and might make the ghosts stand out a bit more(i like how they were programmed, btw. very inventive).
props all around!

Unfortunately, because of an optimization I used, I can't use grayscale in the game loop.  (The backbuffer is taken)

BTW, any ideas on a routine for controlling the ghosts are appreciated.  :)

EDIT:
Also, how do I display any input I get using the input command? 
Quote from: Commands List
Don't forget, its a string of tokens, not characters.
I am confused by that.  Thanks!

This.

EDIT: Wow, really? Thumbing me down for jokingly pointing out a bug in Chrome? Maybe the omnimaga community is worse than I had thought...

EDIT 2: Well it seems that my comment was poorly worded and off-topic, so it wasn't taken well. Which I guess is my fault. I won't delete my previous edit so others can see it if they like, but it's my rash overreaction to my poor attempt at humor being negatively received. I don't hate the omnimaga community... I'm not neutral towards the omnimaga community... I don't like the omnimaga community... I love the omnimaga community. It's the site I spend the majority of my time online at, it's the site I spend the majority of my time reading, and it's the site I spend the majority of my time producing content for. If omnimaga disappeared I don't know what I would ever do, because it has become a core facet of my life. And I'm sorry for ever having said otherwise.

I'm not sure what else to write, I think that's about it. Sorry.

Runer112 people are free to use CODE tags in spoilers if they want (although I don't see why it's that necessary since guests can open them anyway). In Opera not doing so stretches the page like crazy when there's data inside code anyway and those users aren't complaining. Maybe you could fix the spoiler tag mod for SMF? http://custom.simplemachines.org/mods/index.php?mod=195

Plus this was totally off-topic anyway.

Anyway The game looks nice so far and I hope you finish it.

EDIT: I saw your first edit but thank you for your 2nd one. Personally I am starting to question the legitimability of my position at Omnimaga.
