Blender 2.42 preview 15 (updated with bugfixes)

Post by Erwin Coumans »

Another test build for Blender Game Engine with Bullet physics:

- bug fixes in crashing armatures (should fix issues reported in this thread)

- some bug fixes in Bullet physics system, raycast and broadphase
- added 'dynamic' only, without rotation, useful for character control (using a special hinge constraint)
- vehicle using hinges and cylinder shapes (only for 4x4 wheel, not recommended for faster driving, use the raycast vehicle instead)
- Bullet with collision sensor on added objects
- deterministic behaviour (no use of quickstep, but Bullet sequential impulse constraint solver, without randomized constraint ordering)

Nice work Erwin!

With support for dynamic rigid bodies adding most of Sumos features to Bullet ( if not all ), will it be possible to have Bullet as the default games engine for 2.42?

hi, i tested on the game i've been working on, and currently the preview 14 build doesn't crash, but seems to loop infinitely - so it has to be quitted anyway.
In previous builds it sometimes didn't crash - if there was a bug in script , but a serios one, eg in syntax, so the script didn't compile, sometimes really crashes are connected this way with python,...
and yes, now i tested, it's the same with this build, please, try my file -

http://plant.ffa.vutbr.cz/~novak/dwnflz ... wins26.zip

try to run it, then hit escape it should stop and do nothig(loop?), after that do another test, load it, add a stupid bug in the script called engine , then run and escape. maybe It could be just because the armature controllers don't get added this way at all, but i don't know, usually it happens if there's a such script with always actuator.

Certainly, some crashes had to do with constraints, as you've written in the cvs commit(i read cvs commits so i know what's happening), but i cannot test with my file currently.

regarding my crashes, they maybe have to do something also with car, i don't know, before i also used p2p constraints, but they are out now.

Yes, and i found another little bug with the new dynamic nonrigid objects - if you start my file, notice that material friction isn't applied(the actors slip of slope), until you move them - then everything works perfectly.


and yes ---- Thanks !!!
