Bepu + Monogame + VB

Post by Munty Scruntfundle » Sun Jul 28, 2019 10:55 am

Hi folks.

Could you please answer a couple of questions before I start a journey that wastes hours of frustration!

Can I bolt Bepu into VS2017 using Visual Basic and Monogame? There's now a working VB template in the last Monogame release which I'm very thankful for, that's all working great.

I'm working on a couple of 3D game ideas which are going to push physics well beyond what I'm prepared to put time into. I'm ok with physics, but mesh v mesh is possibly past my abilities. I've done loads of 2D stuff, but I don't want to write a 3D engine.

Think pfs, pin ball machine, car on a track, space flyer with collisions. That's the kind of thing I need to accomplish. Small mesh travelling on a larger mesh, collision detection, I'm happy with impulse responses as long as they resolve sensibly. At this point I don't need elasticity, but it may well be useful in the future.

Anyway, that's all waffle, the main question is - can I use Bepu2 with VB and Monogame? And are there any examples of this bolted together and working?

I should add if I need to translate a load of C# to VB that's fine, it's the underlying differences in compilers that worries me, would I be hassled with having to rebuild a load of stuff and manually bolting things together?

Many thanks.

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 around it that hides and abstracts all of that, likely incurring some mild overhead.
- I do not think v2 will compile directly in VS2017 due to the language features used. This shouldn't be a problem if you package it up behind a wrapper library made in VS2019, but it does add a layer of complexity. I'd recommend just using VS2019 directly if at all possible.

2019 is not a problem, well, I haven’t put my cone into it, but I can’t see anything that would be a problem.

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

Thanks for the info. :o)

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