[RESOLVED] dissapeared objects

[misty basin]

Hello, can someone please review my code and tell me why I cannot see any object?
They have dissapeared as I started to play with the MeshPickingExample code. I seem to cant figure out why.
Thanks

What can you see on screen?
Is the camera perhaps just pointing somewhere else?
Or too close to the ground, so your objects are out of view?
Or too close to the target, so your cube is being culled?

There's nothing in your code that immediately stood out to me as an issue.
I think whatever your view::pan_orbit_camera is doing might play a part in this.

Albeit that's just speculation on my part, it could very well be something entirely different

[misty basin]

Thanks for checking this out. This is what I see. I have tried to replace the pan_orbit_camera with the original one from the example. No change.
This is the example: https://bevyengine.org/examples/picking/mesh-picking/

its quite hard to understand whats going on here, but i recommend using something like bevy_inspector_egui to view and potentially edit the components of your entities live, like making sure the camera isnt bugged and pointing in the entirely wrong direction, manually moving around the static meshes by editing their transform to see if you can get them moved into the camera view, etc.

Thanks, didn’t know about bevy inspector, will check that out 🙂

It seems the bevy_inspector_egui has some compatiblity issues with bevy 0.15, did you get it working for this version?

[azure vector]

it has a release for 0.15, so it should work (tho i haven't used it myself for this version). whats the issue?

oh, bevy_mod_picking is a very old version. you don't need that at all anymore since 0.15 made picking part of bevy itself

so that old version of picking is pulling in a old version of bevy_render which requires a old version of web-sys - this means you get this conflict when you try to also add the inspector, which requires the recent version

you should have gotten issues long before this tho, using bevy_mod_picking for bevy 0.12 with bevy 0.15....

@misty basin tldr remove bevy_mod_picking, its old

[misty basin]

thanks for pointing out whats going on with cargo, Ive removed the bevy_mod_picking and Ive got the egui up and running

I see few strange (strange to me) things, Camera has viewport set to None and there are zero visible entties. If I set camera to Some which is the only other option the buttons dissapear.

Ok, so visible entities and camera None viewport are both fine, this is from the example code.

Think I found the reason, this is from my app, there is no mesh nor material assigned to the entities

[inland crater]

They have mesh and material, but they are missing the visibility components

[misty basin]

I dont see that in the example code, any idea why do I need to add that for my code?

[inland crater]

you created you own Mesh3d and MeshMaterial3d, you should use bevy's one

[misty basin]

Thanks, that was it.

And also the camera was a bit misplaced, I made a typo
