oimo.js constant impulse

[dbawel]

@adam -

Yes, I corrected the applyImpule vector. But if you're patient and wait a couple of minutes, you'll see most of the spheres eventually settle on the borders and corners - whereas this doesn't occur using cannon. Changing the WORLD.SCALE is a dramatic improvement. However, my current project is to replicate human biological cells moving in a space which requires that all cells maintain a constant impulse, and cannot gather on the border collision objects. With a restitution of 1 or higher on all objects (and no friction), this should be the case in Oimo, as it works fine in cannon and the objects never settle - especially on the borders.

Thanks for making progress on this, and I'm sure it can be solved in Oimo.

Cheers,

 I think I might have it:

restitution is set to 1 and friction is set to 0 for all bodies.

Probably ought to be added to the default oimo BJS plugin?

I just submitted a PR.

And I've just validated it  thanks a lot

@adam - I believe you have done it! I have been declaring friction in so many tests, but haven't sice you declared adjustments to the physics engine, I will be implimenting Oimo back into my scene, and benchmark 800 meshes (300,000 polys) to see if I cn improve the fps - even thogh I have it working at 50 -60fps now. But I like the behavior using Oimo much better. Thank you very much for putting your time and effort into this, as I might expect it to be of value to many users.

Cheers,

You rock for tracking this down!

I'm still really surprised that such a small scaling factor would make such a big difference. I guess oimo is more sensitive to such things than other engines I've worked with.
