I want to use the physical method setAngularVelocity to rotate the box, but it will slowly deviate from its original position. Which constraint method should I use to constrain it to be fixed to the floor? Hinge? 6 Degrees Of Freedom? Slider? I can’t seem to understand their parameters~ > **[Babylon.js Playground](https://playground.babylonjs.com/#Z8HTUN%23971)** > > Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes ---

cc @Cedric, but it does not seem to deviate from its original position when I test your PG(?) ---

Do you want to keep the position from moving when rotating? > **[Babylon.js Playground](https://playground.babylonjs.com/#Z8HTUN%23972)** > > Babylon.js playground is a live editor for Babylon.js WebGL 3D scenes ---

Yeah, so I need a hinge constraint to connect it to the floor. ---
