Don’t have internet at home, but going in the competition anyway…

I saw the theme at about +1 hours after the competition started (about 4-5 hours ago) in an email when I was at a cafe checking my email on the free wireless.  I have been coming up with a basic idea since then, but not giving it all that much thought.  I was thinking about drawing lines on paper, and scanning them in… then making minimal beep noises…

But then I wrote the name of my directory for the game… mini_mal… and aha!  Mini Mal was born.  I haven’t even to the ludumdare website since the comp started, but I imagine someone else has come up with the idea for ignoring the theme 😉

So the idea so far is this… Mini Mal the stick figure, with minimal beep noises.

MOST OF THE COMPETITON I WON’T HAVE INTERNET.  Bugger.

I accidentally had skellington game framework on my computer, along with pygame, and python.  So I’m just going to do a pygame game… with basic stuff.  Luckily I also downloaded the pygame documentation and examples… also lucky the python objects have documentation built in, also lucky I have been maintaining pygame for over 3 years now.

… now my todo…

DONE – window up, and basic event loop.
– basic animation program…
– draw line, click point, click second point.
– select point.
– draw end points of lines with rectangles.  Use collision functions to see which points are selected.

– lines are in each frame of the animation.
– to not show lines in one frame, you can mark them as invisible (somehow do invisible lines differently).
– key frames.
– can add/delete key frames.
– interpolation happens between key frames.
– frames per second.  Set at 30fps.

I made a line class, which subclasses the Rect class.

It can draw itself, with it’s own color…  oooh.  A white picture with a black line on it.

… now to make a screenshot function I think… maybe when I have something a bit better.

– draw line with end points.

It can now draw a line, and select the end points – and move the line

Now to go and get some junk food.

– make a Lines class, that has a def handle_events(self, events): method.
– make a Lines.new_line method.  So you then click to make the two points.
– make a Lines.delete_line method, which deletes any line selected.

Went and got some junk food.  A few lollies, and chips.

Then I had dinner, and then came back to work on a Lines class.  Almost there with being able to draw multiple lines.  Whilst coding, I’ve been thinking of how I can structure the animation editor.  Like how I can make collections of lines play at different positions.  I’ll have to translate the positions of the lines somehow… perhaps I’ll give each set of Lines a transform   Then allow selecting groups of lines, so I can animate multiple groups on the same screen.

Then I’ll need a way to load and save Lines… probably with pickle.

Now to finish off my new_line, and delete_line methods.

… oh, and I need to figure out the actual game part… hrmm.  that can come later, once I’ve figured out something cool.

the lines can be drawn pretty easily now.

Accidentally I came across a way to have the lines join up at the vertices.

Now I have a mode where I can select multiple verts to move at once… which allows a primative form of welding of vertices.

been playing a bit with drawing more… it’s kind of fun.  I’ve made it slightly easier for me to do things, and also experimented with line thickness… That could also be a fun thing to animate.

So the lines could grow thick from frame to frame.

… but how to save them all.

I think the pygame.Rect subclasses only pickle the pygame.Rect attributes.  Oh well.

Perhaps I can replace it later with a vec4d subclass… or something.

Anyway… this is what I want to do I think:

Frames
Frame
Lines
Line

So then I think I can just pickle the whole lot, and reload it.

I put a basic screenshot function in there.

– Create Frames class, get basic animation working.
– Make a box select.  So you can easily move many lines at once.
