Mouse picking intersection doesn't update on camera move about bevy_mod_picking HOT 4 CLOSED

@Sheepyhead this is resolved in PR #78 and #68. Default behavior now results in picks being updated every frame for the cursor pick source. The 3d_scene example has been updated to show this new behavior by animating the camera.

Hey, thanks for the report! I'll have to see if this is happening in the debug cursor, or in the actual picking systems. I think the intent here is to only compute picks during a mouse movement, instead of running constantly. Some ways we could specify the always-on behavior:

1. In your world movement systems, send a callback to the picking system, letting it know it will need to run a check this frame because you've moved things around.
2. When setting up the PickingSource, there could be an "always-on" mode you specify.

Let me know if you have any thoughts on this! 🙂

As shown in the example it also applies to the intersection returned by InteractableMesh, so the debug cursor is accurately showing the intersection it's returning. Now what I'd personally find most useful is to have a setting for PickingSource that it keeps updating the intersection even when a mouse button is held, personally I'd consider that the expected behavior, but leaving it as an option is fine

I've been thinking about this a bit - I think you are completely right in that this should be default behavior. The plugin really doesn't work as intended if the scene isn't static.

1. By default, picking should update every frame any time the window is active (focused).
2. We can supply options for update behavior (always, while window focused, on mouse move, etc.)

PR #68 gets us most of the way there. I will need to make some new test examples to verify this is working as intended.
