Issue is that you have an entity which belongs to the UI world as a child of an entity that belongs to the 2D world...
NodeComponents is placed by the UI flex systems, and need all of it's parent to also be placed that way. SpriteComponents isn't, it's placed by the 2D systems, and as such doesn't have the components needed for UI placement.

This could be better handled by the engine... but if you want to get around the failure, just don't mix UI components with others...

Ok...so how can i display a text in my 2D world, which is a child of another 2D component?
Before using NodeComponents i simply tried to use TextComponents, but got the same error. From the name of it, i expected TextComponents to simply work.

I’ll still mark this as an inappropriate crash and leave this open until we have something more graceful when this happens.

Cool. Could one of you two be so kind and tell me how i can add text as a child to a 2D component?
I can't seem to find it.

As per Discord, Bevy currently only has text rendering in the UI render pipeline. For 2D and 3D that still needs to be implemented. 2D could potentially be rather easy, when one can reuse stuff from the UI pipeline.

Would anyone like to collaborate with me to implement the 2D functionality for this? I'm thinking of digging into this some time next week.

Documenting info I learned from @cart in Discord:

  • The implementation should live within bevy_text
  • The general approach is to mimic what the TextBundle component and draw_text_system system are doing, without the UI-specific stuff.
  • Specifically, we will use DrawableText
  • We'll use a MainPass component to hook into rendering via Camera2dBundle. More generally:
    • The presence of a MainPass component causes things to be rendered by Camera2dBundle/Camera3dBundle
    • The presence of a Node component causes things to be rendered by CameraUiBundle
    • The determination of the actual camera is done via the name of the camera...somewhere

Thanks to @PabloMansanet's help, the implementation is ready for review/testing. Give it a try! #1122
