btKinematicCharacterController with a btMotionstate - how?

I've seen this question asked twice before, sort of: Using MotionState with CharacterController btKinematicCharacterController and interpolation The first of these seems to have only been asking because they thought a motion state was the only way to get a world transform from an object, and the sec...

Re: Maya Bullet noob questions

That's 9.8 metres per second per second - it's an acceleration. So after 1 second, your object should be travelling at 9.8m/s, but it won't have been at that velocity for the whole of the first second, and the distance travelled will be less than that. To get it to fall 9.8 metres in 1 second, you'l...

Re: Readblend for Blender 2.5?

Thanks Erwin, that's all I needed to know :) I'll have a thorough poke around the GameKit code and post any questions on the GameKit forums. FYI, I'm looking to write a Blender to Ogre mesh converter, as an external tool rather than as a Blender plugin.

Re: Readblend for Blender 2.5?

I'm just asking about readblend, not Bullet (although eventually I will want to extract physics information from the blend file). I just want access to the geometry, materials and animation, and I'll process them myself, all I want to know is if readblend will work with Blender 2.5 blend files, as I...

Readblend for Blender 2.5?

I'm looking at writing a command-line tool to grab data from .blend files, and readblend seems to be the only real option at the moment. Before I set off down that path though, I'd like to know, does it support files saved by Blender 2.5?

Thanks!

Re: btVector3 and others not initialized to (0,0,0) by defau

Sure, I understand why it's been done that way, I'm just saying I'd prefer a default constructor (and guessing that most other users would too). But then I like to do convoluted things like fill containers using std::generate or std::transform instead of default constructing and overwriting, to gain...

Re: btVector3 and others not initialized to (0,0,0) by defau

Hah, I just ran into the exact same problem! Except it manifested itself in setting collision shapes with vertices in crazy far away positions, resulting in rigid bodies that didn't move. Very hard to find. "Performance" is not a good reason for this, in my opinion. There should be a defau...
