Or, alternately, have the "update" method except (for example) a hash of named arguments as an optional second parameter, or an argument array, in the parent class. Then you can override using as many additional components as you wish.

*args and *kwargs, dude.

[Berserker]

This works also, just make the "param" optional parameter.

Code: [Select]

class Animate:
    def update(self):
        print 'Animate update'

class Player(Animate):
    def update(self, param=None):
        if param:
            print 'Player update with parameter',param
        else:
            Animate.update(self)


player = Player()
player.update()     # Prints Animate update
player.update(1234) # Prints Player update with parameter 1234

The "param=None" means that you don't have to give that argument. If you don't give it, it will be None and the Player.update calls Animation.update.

Have you tested that it works, or do you just think that it should?
If Python doesn't do method overloading via separately defined functions, then even optional parameters change the signature, causing an error, I would think.
Python isn't my native tongue.  It's strange way of handling things never appealed to me much.

[Berserker]

Yes, I tested it. The update in Player replaces the update that it inherits from Animation regardless of the parameters.

Here's an update.

Added a whole new universal file format and lots of uses for it, added animated sprites, added menu states with widget-based GUIs, parallax backgrounds, camera zoom, tiles, tilesets and tilemaps, fixed the collision code, added elasticity (press Space to become bouncy!), and even added loadable levels! Have a look at the data folder. especially the *.z* files.

So, um, I may have just used a python interpreter to open 100 more python interpreters. It takes about a second to actually type a character now. :3

I'm so proud!

*manly tears*

[MadocComadrin]

I was going to have all of them open another 100 interpreters each all at once, but that would probably cause some sort of high-level implosion that would result in everyone wrapping around back to using punch-cards.

Stop working so much faster than me! >_<

Haha, definitely gonna check it out when I get home, sounds pretty cool.

Meanwhile, I've come across the problem of their being no easy way to save a json file with javascript - so I'll probably have a button to display the raw JSON (which you can then manually save to a file) and a button to send it as a post request to some php on the server to create the file there (assuming you aren't running it locally, which I would like to preserve if possible).

[MagmaMcFry]

Updated again.

New options menu with configurable (and saveable) key bindings! Also, fixed the collision code. Again.

I also think I broke Skyrunner and made her hate linux.

Perhaps trying to link libraries and compile in linux via the code blocks IDE wasn't the best first task for an introduction...

Depending on how old a browser you want to target, consider web storage for saving state.

Or cookies: for smaller amounts of data.

[GlyphGryph]

The problem is that both sorts of saving are temporary and difficult to transfer - the exact opposite of what I want for map and tile definitions (though perfect for things like, say, save states).

[Skyrunner]

So... save files. I need to touch on them some day.

I think C++'s fstream/ostream/istream are horridly inadequate for this usage. Any libraries out there that might be useful? Maybe Boost::Filesystem, or Boost IOStream-state?

Also, if not the stream-state library, how should I save stuff? Should I output plaintext along with variables, like

Code: (plaintext) [Select]

HP = 100;
MaxHp = 100;
Inventory = (5,3,2),(5,6,43);
or just variables in binary... or use XML? @_@

I think the map files will have to be saved separately from the other variables, though. They're huge—my program was using 10 MB of ram with just a single map open.

Anyhow: So many choices.
