Struct RotationConstraints

pub struct RotationConstraints {
    pub allow_x: bool,
    pub allow_y: bool,
    pub allow_z: bool,
}

Component that restrict what rotations can be caused by forces.

It must be inserted on the same entity of a RigidBody

Note that angular velocity may still be applied programmatically. This only restrict how rotation can change when force/torques are applied.

Example

fn spawn(mut commands: Commands) {
    commands.spawn_bundle(todo!("Spawn your sprite/mesh, incl. at least a GlobalTransform"))
        .insert(CollisionShape::Sphere { radius: 1.0 })
        .insert(RotationConstraints::lock()); // Prevent rotation caused by forces
}

Fields

allow_x: bool

Set to true to prevent rotations around the x axis

allow_y: bool

Set to true to prevent rotations around the y axis

allow_z: bool

Set to true to prevent rotations around the Z axis
