Is there any way to disable gravity in Matter.js? I want my objects (bodies) to keep their physical abilities (like reaction to collision, restitution, friction etc), but I'd like to prevent the reaction to device's gyro and orientation change.
Try
engine.world.gravity.y = 0;
where engine is your engine instance.
