Physics Debugger Improvements

Hello,

We've been reworking some of the UI/UX aspects of the built-in physics debugger lately, and I'd love to share some early progress with you on this thread. Here is a link to an experimental build that I've prepared: https://beta.unity3d.com/download/cd910d1ebf55/public_download.html

Here is a short description of what has been addressed so far:

• Split the Physics Debug window into Filtering, Rendering, Info, and Contacts tabs for easier access and space management

• Moved the Rigidbody and Articulation Body info sections to the Info tab (and added some more info for debugging)

• Added the option to visualize the center of mass or the inertia tensor of Rigidbodies or Articulation Bodies that are being tracked in the Info tab

• Added Contact visualization that can be filtered by using settings in the Filtering tab

Known limitations:

• Changing filtering settings while stepping frame by frame during Play Mode will not take effect until the next simulation step
  
  
• Turning on the Show All Contacts option during play mode will not show contacts of Colliders that have already been initialized.

Things that are being considered:

• In addition to being able to filter by Physics Scene, add an option to filter by Unity Scene.
  
  
• Expose Rigidbody and Articulation Body velocity and acceleration accumulators. This could be employed to get an estimate of the total external force applied this frame

Let me know what you think, can’t wait to hear any feedback.

Hmm, the transparency could definitely be bumped up here.

Just checked this, and it seems to be working for me. Is the "Inertia Tensor" enum selected for the child?

Thanks for the feedback!

 

Good idea and I don't think it would be difficult to implement. Thanks for the feedback!

Weird, I'm still unable to reproduce the issue after following your screenshot as closely as possible. If this is an issue that you can consistently reproduce, could you provide the repro steps? I'm really curious why this is not working for you.

 

Thanks for your continued interest in physics!!! <3

 

Hi, this might be overdue but the per-contact impulses are now exposed and used in this build. This will also be included in the final product. Thanks for taking a look!

 

Just to refine on what Augustinas just said, per-point contact impulses is in a PR towards trunk now, expected to land sometime soon, and become available in a public alpha of 22.1. I can totally remember you asking about it since forever.

 

Here's a new build with query visualization added:
https://beta.unity3d.com/download/25827f979846/public_download.html.

There is query visualization for check, overlap and cast query types, and the visualization can be filtered independently in the new "Query" tab. Here's a gif of the visualization in action:


Also, the Info tab is now at the start of the row + some other minor fixes.

 

At the moment, no. But definitely, a thing to look into. Thank you for your interest! <3

 

This is a quick note to let you know that the UI&UX rework that was described at the start of this thread has landed 2022.1.a10. The rest will come shortly afterwards.

 

Hey, a quick update: a second batch of this work has landed in 2022.1.0a14. It includes contact and query visualisation, support for multiple scene views, addressed the limitation:

What's still in the queue:

• Filtering by Unity Scene in addition to filtering by Physics Scene
• Performance improvements to the contact and query visualisation
• A getter for forces that have been accumulated by a Rigidbody or an Articulation Body

 

Added a backlog entry for this.

 

Yep, all of this is available from 2022.1 and newer.

 

I can only tag @MelvMay for this one.

Done. Available from 2022.2.0a14 and up. Exposed the flag for Hinge and Configurable joints + equivalent flag for Articulation Body drives:

 

Not when but yes it will. For 2022.1 we landed a whole bunch of things that fully occupied the release. This certainly wasn't a priority. Ideally we'd like to see that in the follow-up release but no guarantees.

 

You can make the debug physics window a tab indeed, and then it's fairly unobtrusive and will keep the Scene info present forever. Otherwise, once you close the window itself, the debug viz is gone I'm afraid.
