Yay, game submitted in a PM to Onewing! (Hope that's what I was supposed to do.)

It may be a short lived library, but effectively a library is just reusable code and that's what it is.

In Allegro's case there's likely a performance justification for leaving that state tainted (but heavily documented!): if Allegro were to try to capture the initial state and restore it for each relevant OpenGL operation it would likely cripple the library's performance. That's a valid concern. I think it's terrible that OpenGL bleeds into Allegro 5, but I trust that it's necessary (if it isn't then Allegro shouldn't be doing that either).

If it affected your library then you could readily argue that it was justifiable to alter the global state without restoring it, but in this case I don't think that's applicable. The affected bit of your library seems to predominantly initialize state a single time for later, which can certainly absorb the negligible impact of capturing and restoring the state. The runtime cost is much less than the developer cost.

Here is global state rearing its ugly head. It's a problem. That is why the industry has agreed that global state is problematic in general and that it should be used sparingly. I imagine that attempting to use this code in a multithreaded program that was "crazy" would be impossible. Perhaps some of that burden would hinge on Allegro, OpenGL, and physical hardware, but to whatever extent is possible, the software should not be a limiting factor.

Hello everybody! Hope everyone enjoyed KrampusHack and more importantly, had a great Christmas! Or...vice versa.

I've received several entries. A surprise family event popped up that I'm going to head off to now. I'll send out the gifts this evening and you'll have the rest of the week to play them before the Secret Santas start posting to the allegro.cc Depot forums.

Yep !

Distribute the submissions which you have already received. Then let the rest trickle out as they become available.

Oh noooo...

I still haven't finished my game. Well, I'll continue working on it. It appears Santa had a bit of a liftoff delay!

Certainly the deadline is meant to be motivation for a "hack" event. Obviously a floating deadline is therefore demotivating. That said, the whole event was kind of whimsical this year so if you're motivated to get something done still I don't see the harm. But certainly the next KrampusHack should be more precisely defined.

I received my gift. It's a blast to play!

What the Hell kind of keyboard do you have?!

Interesting. Are you left handed?

For most desktop keyboards, yes, but laptop keyboards might have the cursor keys close enough for that not to matter.

That's a wrap on KrampusHack! Thanks for participating! Here's some info:

Participants that received gifts:
Eric Johnson got a gift from Amarillion
Mark Oates got a gift from Eric Johnson

Derezo got a gift from Elias

Participants that did not get gifts:
Edgar Reynaldo did not get a gift from Derezo or GullRaDriel (late entry)

You can now upload your games to the depot. I can see several people have already done so.

Thread credits go to those who completed and provided games.

It's still the first of January and I'm packing my entry.

UPLOADED FFS !
