An optimal solution to bodies staying upright

[B0ryskart0n]

Hey everyone,

I'm programming a side-view game and I want my sprites to not rotate and always stay upright as spawned.

I initially thought that setting the AngularMomentum::ZERO would be a simple and simulationwise stable solution, but I then get a warning: "Dynamic rigid body 71v0 has no mass or inertia. This can cause NaN values...".
Now I doubt that this is the right approach.

What would you say is the right approach for limiting rotations of sprites?
Or is my requirement unreasonable and I should maybe not be using Dynamic, but rather a Kinematic body?

For dynamic bodies, you're looking for LockedAxes
