Real-Time Physics Simulation Forum

As part of researching how to best integrate a physics engine into my game, I was looking at the source code for Urho3D. For the most part what they've done is pretty straightforward, however for implementing ghosts or "triggers" they're using a btRigidBody with the 'CF_NO_CONTACT_RESPONSE...

I'm currently trying to integrate Bullet into my game (which uses the Entity-Component architecture, very similar to Unity's), and I'm a bit stuck on the best way to proceed. Should the Entity's get btCollisionObjects, or should the Components? How do I deal with parent-child relationships between E...

Is it possible to have objects who's position/rotation may be set arbitrarily by the application, as well as participating in the physics simulation? If 'btMotionState' had some sort of way to mark it as dirty that Bullet could detect, that would be perfect

Thanks for the feedback! Looking through the API, I think I'll be extending btMotionState, since that seems to be the easiest and cleanest way to implement things while also allowing me to keep using my own API. After some initial testing with the debugger, I noticed that "getWorldTransform&quo...

Hi, I've been pretty successful in hacking the bullet Hello World program into the game I'm developing, and I'm beginning to consider how I'll be integrating it into the rest of my engine. At the moment I'm using a custom math library, with all the standard types (Vec2/3/4, Mat4, Quat, etc). I've be...

Hi, I'm trying to integrate Bullet into the game I'm building, and I'd prefer to keep things kind of light. Bullet seems to be decomposed into several different modules, but I'm having trouble finding information on what does what, so I can decide which ones I don't need. In particular, I don't need...

Is the MatrixX class used for custom sized matrices? I can't seem to find anything on it in the documentation.
GMTL might be nice, but if possible I'd like to use Bullet's library

Thanks,

Hi, Just as a note, I'm pretty new to this whole area of CS, so please forgive anything stupid I might say. I'm working on creating a game engine using OpenGL as my graphics API. I was getting tired of GLM because its quaternions and transformations were just hard to work with, and I'd heard that Bu...

Hi! I've been working on writing my own game engine in c++, and as I started making games in the blender game engine many years ago, I thought it seemed fit to integrate the bullet physics engine into my own engine. I've been following the tutorial at http://bulletphysics.org/mediawiki-1.5.8/index.p...
