Transform reset after inserting pbr bundle | Bevy | Page 1

I have an entity that already has a transform, and want to give it a mesh afterwards. in the code below I am trying to preserve the transform in two ways but its not working:

fn init_player_system(
    mut cmds: Commands,
    q: Query<(Entity, &Transform), Added<Player>>,
    mut meshes: ResMut<Assets<Mesh>>,
    mut materials: ResMut<Assets<StandardMaterial>>,
) {
    for (entity, transform) in &q {
        cmds.entity(entity).insert(PbrBundle {
            mesh: meshes.add(Mesh::from(shape::Cube::default())),
            material: materials.add(StandardMaterial {
                base_color: Color::GREEN,
                ..default()
            }),
            transform: *transform,
            ..default()
        }).insert(*transform);
    }
}

I feel like this should work, with the code above does it also resets the Transform, or does it not insert the PbrBundle at all (in which case maybe it's a problem of flushing the Transform before)?

Alternatively, you could just add the components of PbrBundle individually, there are not a lot of them, just Handle<Mesh>, Handle<StandardMaterial>, and potentially VisibilityBundleif your entity doesn't already have it.

fierce nymph <@497455206762676253> I feel like this should work, with the code above does it...

this is how I am adding the original entity (on the server) cmds.spawn((Player(*client_id), TransformBundle::from_transform(Transform::from_xyz(0.0, 500.0, 0.0)), Collider::cuboid(0.5, 0.5, 0.5), RigidBody::Dynamic, Replication));

#

is that the issue?

I need more information:

with the code that you showed first, what is the outcome: does it reset the Transform, or does it not insert the PbrBundle at all?
in which schedules are you adding the TransformBundle, and the PbrBundle?

the code I showed is resetting the transform, pbr bundle does get inserted. the transformbundle gets spawned in update when a player joins, and then should get replicated to clients (bevy replicon) and then on the client for every added Player, a pbr bundle is spawned in update

Are you sure your setup uses the correct transform for the client? Maybe it's not inserting the PbrBundle that resets it (I think your code above should work) but it's before that?

yeah it seems like its happening before inserting the pbr, because I just removed the system and it still spawns at 0 0 0, instead of the 500 y I set it to. not sure how that is possible because these are the only things interacting with the entity

I'm not familiar with bevy_replicon so I can't really help with that part, sorry ^^'

fierce nymph I'm not familiar with bevy_replicon so I can't really help with that part, sorry...

it does not seem to be bevy replicon either, just disabled it for that object and its still not working

#

the transform is maybe getting reset by the collider or somethign

fierce nymph Sep 10, 2023, 9:59 AM

#

I thought it's bevy_replicon that spawns the object on the client side?

static wedge Sep 10, 2023, 9:59 AM

#

yes, but on the server the transform is already wrong

fierce nymph Sep 10, 2023, 9:59 AM

#

ah

static wedge Sep 10, 2023, 9:59 AM

#

as soon as it spawns

fierce nymph Sep 10, 2023, 10:01 AM

#

static wedge this is how I am adding the original entity (on the server) cmds...

With this it should spawn with the transform you gave, so maybe you do an insert later?

static wedge Sep 10, 2023, 10:04 AM

#

wait, it seems like bevy_xpbd is using its own position instead of the transform

#

maybe that is whats happening

fierce nymph Sep 10, 2023, 10:06 AM

#

Ah yeah definitely

#

It might change in the future but for now it's the Position you need to set

#

I should have thought about that I did the same mistake :')
