Finally getting somewhere!

PhillipNguyen on 2011/04/09 03:02 of TinyTinyMonkey

Had enough time today to get in some good work, and I think I'm finally done wrangling with pymunk to make it give me a platformer.  And I have a working time machine!  Unfortunately it only seems to work inside the game, otherwise I'd go back a few days and do some more coding.  Here's my first screenshot.  Why is that alligator wearing a top hat?  What's going to happen to that baby?  How long has it been loitering by that sign?

That looks awesome!

That's baby #1... How many babies have already been claimed?
Sweet graphics, though I'd kinda like pointier alligator teeth.

This makes my graphics feel so inferior

when I run the game:

Same. Also I tried moving the pymunk/ dir out of the way and using my system's pymunk, and it crashes as soon as he first touches the ground.

Segfaults, I mean.

I got a segfault when I put three babies on the bridge.

2mauve: most likely that's because your system pymunk is version 1.0.0, which requires an explicit init_pymunk() call, while version 1.1.0 bundled with this game, does not. Sadly, the game doesn't work with version 1.0.0.

Aargh.  Sorry, I don't think I'm going to be able to fix this :( 

It looks like maybe the included chipmunk dll for 64bit linux was compiled with the wrong version of chipmunk?  The only linux I have to test with is 32bit and I'm not getting the same problems.  I attempted to get it working with pymunk 1.0.0, but ran into a problem with climbing the ladder.

You might try downloading the 1.1.0 version of pymunk into the game directory, and rebuilding the chipmunk library with "python setup.py build_chipmunk" inside the pymunk source directory.

@kent_turbo: are you running 64bit linux too?

kent_turbo on 2011/04/10 16:55:

I use 32 bit version.
