LDTK region strange in runtime

[darkautism]

pub struct PlayerChatBundle {
    #[with(player_chat_collider)]
    collider: Collider,
    #[with(player_chat_active_events)]
    active_events: ActiveEvents,
    sensor: Sensor,
    #[with(Dialogue::from_field)]
    pub value: Dialogue,
}
fn player_chat_active_events(_: &EntityInstance) -> ActiveEvents {
    ActiveEvents::COLLISION_EVENTS
}
fn player_chat_collider(ei: &EntityInstance) -> Collider {
    info!("{:?}, {:?}", ei.grid.x as f32 / 2., ei.grid.y as f32 / 2.);
    info!("{:?}, {:?}", ei.height as f32 / 2., ei.width as f32 / 2.);
    Collider::cuboid(1. , 1.)
}

In main.rs:
            .register_ldtk_entity::<PlayerChatBundle>("PlayerChat")

I have testd these collider

Collider::cuboid(1. , 1.)
Collider::cuboid(ei.width as f32 / 2., ei.height as f32 / 2)
Collider::cuboid(ei.grid.x as f32 / 2., ei.grid.y as f32 / 2.)

The first region work great after i set Collider::cuboid(8. , 8.), 16*16 in ldtk editor.
But the second region size strange again.

It seems ldtk entity will change Collider i created.
So i don't know what is right way to set a collider sensor for region which i want to active some game event. What should i do?

My best guess for what's causing this is bevy_ecs_ldtk's logic for scaling entities. It basically does transform.scale = entity_instance_size / entity_definition_size..

So it looks like maybe you've tried this, but what happens if you hardcode the cuboid to be half the size of the entity definition? This value specifically:

I tested this.


Only first region is fit.

I see - thanks for elaborating on that.

It's a very strange issue. Out of curiosity - does the collider shape change at all if you switch them? Like registering the PlayerChatBundle to the ToolTips identifier? .register_ldtk_entity::<PlayerChatBundle>("ToolTips")

[darkautism]

It seems different size have different behavior.

[Trouv]

Could you use bevy-inspector-egui to find out the scale of those entities? Or print them in a system? It looks like the left one is supposed to be (10,12,1) and the right (1,10,1),

I think I have an idea of what might be happening. It looks like you might be using a Tile field on the ToolTips entity? What happens if you remove that field?

[darkautism]

It seems ok if i change tooltip tile to square.

#271 should fix this. I'd ask you to try it but there have been a lot of breaking changes since 0.8 that could be annoying to deal with
