Door collider

[marko-lazic]

Inserting and removing the collider component could be an option, but I am interested in finding a way to mutate and disable the collider to allow other objects to pass through and then re-enable it again.

There is a ColliderDisabled component that can be inserted to disable a collider.

Seems like ColiderDisabled does not work fully for me. Disabling works:

commands.entity(door_event.entity()).insert(ColliderDisabled);

But there is no way of re-enabling it. The removing component does not do the trick:

commands.entity(door_event.entity()).remove::<ColliderDisabled>();

However, this just removes the component and event that is supposed to re-enable the collider does the following:

for (handle, _) in changed_disabled.iter() {
    if let Some(co) = context.bodies.get_mut(handle.0) {
        co.set_enabled(false);
    }
}

The code snippet is from bevy_rapier/src/plugin/systems.rs/apply_rigid_body_user_changes()

Still, the door is walkthroughable.

My Collider component was inserted together with RigidBody::Fixed. I noticed if I update transform (move a bit the entity), the door starts to collide. When switched to RigidBody::KinematicPositionBased the door collides as expected when adding and removing ColliderDisabled. So I will take the KinematicPositionBased. 😊
