Official MARS Direct Placement Example

This was much needed and very helpful in moving forward.

I'm seeing something slightly bizarre that I was hoping you could help clarify:

When building and running on iPhone/Android, the GameObject starts out well placed on the plane (table), however when going "under" the plane/table the GameObject "seeps" through. Curious if this has something to do with the Proxy Forces that's applied to the plane, or alignment related to the Camera/Player position(?)

 

Hi Andrew,

Just to clarify, you can only actually see the placement when running on a physical device?

We cannot run this in the simulator view? and click to place / test / iterate an object in that view?

Sorry, just trying to work out what I can and cant do with the simulator view.

Cheers

 

I noticed this as well, but in general Simulation View appears wonky..
However, you should still be able to do iteration from the standard [Scene] and [Game] views.

 

Thanks for replying!

In modifying your template, yesm the two proxies utilized have forces:
Horizontal Plane & Game object - Snap to Horizontal Surface
(Also fooled around with Snap to 2D Plane to see if that would change anything, but the results appeared the same)

I also had a hunch it mighta been something with the camera.. in the Forces segment of MARS’ documentation, one of the examples talks of making another “Player Reference” for proxies to be aligned with rather than the default MARS Proxy User within the MARS session..¯\_(ツ)_/¯

I’ll attempt coupling the collider and the placed object, but an example would be well received.

Thanks again for the detailed assistance.

 

Is this more involved that adding

obj.transform.parent = objectTransform.transfrom;

within the PlacedObject function?
I attempted appending that to Raycaster.cs in the Example and it still didn't work.

Separately, I started fresh with the project adding Forces to the Proxies:
- Once to ONLY the Object to Place
- Both to the Object to Place and the Proxy Game Object (ie the Capsule)

In all instances the alignment still isn't adhering to the plane and "sinking" below a table.

Feel like i'm running in circles >_<

 

@unity_andrewm
I apologize to bug, but if you could provide an updated streamlined example it would really help.

Regardless the configuration Direct Placement and the use of Proxy Forces aren't mixing well to function as intended.

Thank you

 

I have just tried the direct placement template and I can only get the axes to show. It does not place my objects when I click the cursor in the Game View or Device View. Any idea why that is?

Also Is there any change that the direct placement could include scaling and rotation of the object while placing it? Or could you please give me some hints on how I could code that please?

 

Any ideas?

 

Apologize its taken forever to get back to you. Focused on other things before circling back.

I hate to make this issue seem more trivial than it may be, but even with your modified Raycaster.cs code for direct placement I'm still having the same issue where the object sinks below the plane it is placed upon (ie a desk) when built to a phone. To clarify the raycasting itself seems fine as the object is atop the detected plane, but upon moving the camera down, so too goes the object without locking.

Additional Notes: "Screen Mode" is somewhat confusing, it would seem more relevant to have it Disabled (meaning that it utilizes parent transform events), but building and testing this too yields the same result when on mobile devices.

I'm still actively following this thread and am committed to helping you however I can. Perhaps there's something I still don't completely understand.

Thanks for all the efforts.

 

Is there any more development in this area of direct placement being implemented in the near future?

 

Is there any improvement being released for Direct Placement?

 

the raycaster script has a ton of errors on load. What do I do about that? Does the example need to be modified?

 

This template is working fine for me in Unity (MARS simulation), but not when built on an iPhone 6s running iOS 14.2. I'm not seeing any Flat Surface PlacementTargets with the blue DirectPlacementHighlight, even as the Planes Visualizer is picking up plenty of planes that appear to satisfy the proxy conditions. (I haven't had trouble with other MARS builds to this phone - no issues with basic proxy planes or image markers.) Any suggestions?

 

I know this is a little old, but I would like to get it to work as it's exactly what we want to be able to do.
There is a missing prefab in the scene. See attached. I've tried using Unity 2021.3.8f1, 2020.3.37f1 and 2019.4.12f1

Any help much appreciated. I am quite new to Unity so I might have made a simple mistake.

I am using the latest version of the package posted by mtschoen.
