The demos just use a super simple brute force 'start from scratch, add every single object in existence, every single frame' approach.

The Simulation.Bodies.ActiveSet (which aliases Simulation.Bodies.Sets[0]) contains all bodies which are currently awake, which is a decent proxy for moving objects.

Or you mean I have to use that every thread frame.(Use it inside thread) Yes, in order to wait the correct amount of time, you must constantly be measuring how much longer you have to wait: measuredwaiting.png Is this code tell bepu deltatime? What I have to put in this deltatime? The simulation it...

Thread.Sleep will sleep at least as long as the input value, but is not guaranteed any level of precision beyond that. The resolution depends upon the operating system. On windows, I believe the default resolution is 15.625ms, so you're dealing with very coarse timing. It's possible to force higher ...

Nothing is stopping the body from falling over, so it does. For characters, a common approach is to set the inverse inertia to all zeroes; this gives it effectively infinite rotational inertia and it can't be rotated by any force anymore. So, in your AddCharacter function: var characterShape = chara...

Most of this is just related to using the .NET Framework instead of .NET Core- it handles dependencies in a more tedious way, and doesn't appear to pull in transitive dependencies for referenced projects. You'll need to add nuget references to System.Numerics.Vectors and System.Runtime.CompilerServi...

System.Numerics is distinct from System.Numerics.Vectors. I'd recommend either referencing nuget packages or adding a project reference rather than directly referencing .dlls. If you grab the bepuphysics v2 source and add it as a project reference, its nuget dependencies will be pulled in automatica...

4.7.2 is the earliest version of the .NET Framework which is considered fully compliant with .NET Standard 2.0, so some of the problems you're seeing may be related to using 4.7.1 and below. I think recent versions of MonoGame have begun supporting .NET Core projects directly; that would be the idea...

It think it is because support is false. But what is bool support mean? Support means the character is standing on something. That assert is meant to protect against modifications to the velocity when the character is asleep, since directly modifying velocities does not automatically wake bodies up...

I'd recommend this thread for information about Unity and bepuphysics v2: https://forum.bepuentertainment.com/viewtopic.php?f=9&t=2528 The short version is that there are some unity runtime bugs that get in the way for most simulations, and beyond that, the current runtime does not accelerate the Sy...

View direction is sorta-kinda rotational direction. It is the starting point from which a frame of reference is created. It is projected down onto the surface that currently supports the character to create the 'forward' direction, and then the character's up direction and that computed forward dire...

But I’d still need to wrap for VB? Otherwise C# would be straight forward?

Yup. Or at least as straightforward as the v2 API can be

The view direction passed into the modified UpdateCharacterGoals function is zero, since the character.ViewDirection is never assigned to anything else. Without a valid view direction, the character controller does not know how to interpret the movement direction because the movement direction is in...

It's a bit hard for me to guess without the full context. It could be something wrong with the input target velocity and view direction, or possibly something else like the character not having support, or a number of other contextual things. I'd recommend making incremental changes within the Chara...

You technically can use v2 with VB, but there's going to be some nontrivial work involved and there aren't any examples of it available that I'm aware of. A couple of things: - v2's API is full of non-CLS compliant features, so it cannot be used directly from VB. You'd need to create a wrapper aroun...
