True enough. Perhaps I should write a tutorial for writing out/reading in matrices so this doesn't happen to the next guy tho.

0.62-- If I start writing: local f = assert(io.open("mapdata.lua", "w")) The file goes to the path of the .bat file that's driving, but if I load: love.filesystem.load("mapdata.lua")() It goes to the local path. Of course, I probably should be using love.filesystem but ...

Okay! DT should be fixed, also got first-stage platforming working. Single-tile tracking will only get me landings though, to detect other collisions I need to be tracking the tiles surrounding the player. Basically avoiding the physics library at the moment, I think that's more for kinematic simula...

Ah, yes, it's that quadratic thing: I had the individual timesteps using dt but not the acceleration. Will see to that after the chores and hopefully have time left over to add the actual ability to land on objects tonight.

YES, OF COURSE WE MUST.

Seriously, what is being a developer for, if not to be a merciless punster with the names of important things?

Okay, first, wow thanks for digging that deep, and second yeah I totally misunderstood how that function works. Definitely on my list for another night's experiments. (Tonight I got to successfully identifying if the player is over a specific tile, paving the way to actually landing on platforms.) A...

I think there must be something else wrong as I don't have /that/ great a machine. (It is a quad-core modern machine but it's by no means a gaming rig.) Either I didn't fix the code so it's not regenerating the map every step or there's a version incompatibility I'm missing. I'll run more tests on t...

Um, yes? dt is probably on the list of things I Don't Know Any Better on. It seems alright on my system but I know I'm not optimizing a lot of things properly yet...

Yeah, that it does. Here's the tracker I use:

It takes some learning curve but it can be pretty intuitive once you get used to it. Also, as with so many things on the internet, there's a huge community of MODers out there making cool stuff:

LuaTroid is definitely still at the Technical Demo stage, but I thought I'd throw it up and see if anyone's got flags to throw or wisdom to impart given what's there so far: http://github.com/MaskedRetriever/LuaTroid Navigate with w, a, and d keys, tilde key to bring up the tile selector, mouse and ...
