v1. Lock movement in Y axis.

[AlexCereus]

Hello.

I need to lock movement in Y axis for all objects in space, so they can move only in XZ plane. How can I do it?

Excuse me for my English.

Something like this would work:

Thank you.

The easiest approach is setting two of the rows of the local inverse inertia tensor in every dynamic body to all zeroes.

How can I do it in V2? Which method? I can't find.

The BodyDescription contains a LocalInertia field. You can set that prior to adding it to the Bodies set.

If you want to access an existing body's local inertia, you could use something like:

Code: Select all

ref var localInertia = ref new BodyReference(bodyHandle, Simulation.Bodies).LocalInertia;
