Currently, the StaticTriangleGroup has no internal separation between different loaded meshes. If you need to know if a particular hit comes from a particular mesh, you would need to have multiple StaticTriangleGroups (one representing each mesh). Then, you would need to use a StaticTriangleGroup ra...

I've thought about it in the past; I'll probably make a simple demo of it at some point when I have time.

Regarding the forcefield object, keep in mind that the fieldShape entity shouldn't be added to the space. The forceField system should probably be updated with some of the newer systems in a future version (like the isDetector property of entities or the DetectorVolume). I'm not sure what you mean b...

I can't replicate the issue in the demos so I'm having trouble determining what could be causing it. If you use the default code (both the character controller itself and the character input settings for size and such) for the character controller from the demo, does it still do it? If it does, try ...

Does it ever work, or does it always fail to find any support? If it only occasionally gets stuck, does it consistently happen in the same areas? I don't recall making any changes to the CharacterController, though I'm not sure yet what might have changed inside the engine to cause this. If you coul...

This sounds pretty similar to another recent problem (end of http://www.bepu-games.com/forums/viewto ... ?f=4&t=371). Is the body too short in relation to its width and step height? The capsule can end up with very odd dimensions which appear to cause this problem.

If the sphere doesn't get picked up as soon as you left click on it but rather sits and waits for you to release the mouse button, you can just raycast each frame that the left mouse is held. When a throwable object is hit by the ray, you store it as the currently grabbed object (you no longer need ...

Do you have a reproduction case you could provide? Maybe a mesh where it happens reliably? I'm guessing that it has something to do with the size of the triangles; the convex cast between a large triangle and the flat disc used for its feet can be fairly sensitive. Otherwise, there might be a proble...

One way to do it is to set two rows of an entity's local space inverse inertia tensor to zeroes. This corresponds to two axes of the local space inertia. The effect will be that the object will be unable to rotate around those two axes. In a 2D game, you generally only want rotation to occur around ...

That's caused by the collision margin. You can scale up the graphics or reduce the shape size or margin (but avoid going too small with the margin or accuracy/performance will suffer). You can find more information in this post: http://bepu-games.com/forums/viewtopic.php?f=4&t=409.

I recall having a great deal of trouble with that model in the past. If you haven't already, try to use a custom content processor to extract vertices/indices from the model rather than passing a loaded Model into the initializeData method. The vertices/indices you get from a model can be given dire...

The quickest way to fix the odd rotation is to use conservative angular motion and RK4 angular integration. You can enable them using: space.simulationSettings.conserveAngularMomentum = true; space.simulationSettings.useRK4AngularIntegration = true; There's a marginal performance hit, but it is quit...

Assuming everything has a bounciness value of 0, the leading suspect would be the size of the ground and/or cylinders. The box-box collision detection is handled by a special case which performs much, much more accurately with large objects. Cylinder-box falls back to the default MPR/GJK methods whi...

Right now, it's looking like it will be in March somewhere. A lot can change in between now and then, though.

Adding the tile entities to a StaticGroup and letting it manage them should work. When using a static group, make sure you don't also add the box entities to the space since the StaticGroup will add/remove boxes to the space as necessary. 400x400 (160,000) boxes is going to take quite a while to ini...
