So far today I’ve just been doing some cleanup in my code. I’m about to add a “play” mode so I can try out my levels, which involves having information easily available to know what is solid or not. I’ve updated my tiles.json file to include that information on a per-tile basis, and I’ve used that along with some other things to clean up my rendering code as well. <\/p>\n

I also am considering having the ability to rotate the screen 90 degrees. This way you can see behind walls easier. I had considered other options like a “short wall” mode or whatever, but it all started seeming really un-cool. Here’s a picture of the short-wall mode:<\/p>\n

You can see really easily in this picture how light can leak through walls (those short ones). I haven’t decided on my solution to that problem yet. I think I’m going to have to get this running on the iPad, maybe at the end of this week, and evaluate how fast it is running and if I can afford to do more complex lighting.<\/p>\n

Was about to get after getting the game playing, but I’m finding that jsoncpp is crashing during shutdown of my program. I’m getting a traceback like:<\/p>\n

Turns out this is due to some sort of bug in jsoncpp which makes it not work as global variables. Which I guess the old notion that global variables are bad news is hard to get away from. So I wrapped up all my json away from being globals and it works fine now. Less globals is certainly a good move, whatever the case.<\/p>\n

Next off, I’ve now added a toggle to switch between editor mode and play mode. The editor saves the level state so that whatever happens during play doesn’t permanently damage the level.<\/p>\n

With a bit more work, I’ve got the “play” mode starting to take shape. The player now walks to the tile you click on!<\/p>\n

And now I’ve got a guard running around me like a crazed maniac. The arrows on the floor are special codes that tell the guard where to run.<\/p>\n

I’ve also got animation going on the guards and the player, just sorting out some bugs on those. Tomorrow I hope to get a win condition and a lose condition and some more explosives going \ud83d\ude42<\/p>\n
