I still need information on whether it is possible to create a WebAR application that should be used on mobile phones (Android & iOS). I need the ability to place objects in augmented reality and to select an object that I want to move within the scene.
On iOS devices, I am unable to disable ‘Use Placement Adjustment’ in the WebXR script to prevent moving, rotating, and scaling the object. More precisely, I disable it, but when I run the WebAR application and try to move the object, the entire scene moves instead.
Is this a bug?
Here is my script, I am using Unity 6 and Needle Engine 4.2.2.
It appears you are experiencing an issue with the “Use Placement Adjustment” setting in your WebAR application using Needle Engine on iOS. Here are some key points to consider:
WebAR Application on Mobile: Yes, it is possible to create WebAR applications for both Android and iOS using Needle Engine. You can place objects in augmented reality and manipulate them within the scene.
Placement Adjustment Issue: If you have disabled the “Use Placement Adjustment” but are still experiencing the entire scene moving when trying to manipulate an object, this could be either a misconfiguration or a bug in the behavior of the script.
Debugging Suggestions:
Ensure that all related settings for touch manipulation are correctly configured.
Make sure that the latest version of Needle Engine (4.2.2 as mentioned) does not have known bugs related to your issue. It may be beneficial to check the changelog or update if necessary.
Check how the input events are handled within your scripts for both your moving object and the scene.
It can also help to enable debugging logs to see if any specific errors are thrown during runtime that can give clues.
Script Review: You may want to double-check the implementation in your WebAR scripts to ensure “Use Placement Adjustment” is functioning as expected. You might be able to forcefully manipulate the desired objects with custom parameters.
If you continue to experience issues, please provide logs from your WebAR session for further assistance.
That is correct, but I have not received any news about my question for 6 days. I have already purchased the Needle license, but I am still not sure if I can use this engine for my project. It was said that in the next few updates it will be fixed (if possible), since then we have received several updates, but the problem is still there.
Sorry for the late reply, please feel free to bump questions again and let’s try to keep the conversation in one place by continuing here: webAR game on mobile devices - #13 by Nemanja_Prvulov otherwise it’s getting hard to keep track of it
I’ve bumped the question again internally. As said in my previous reply I do believe there’s not much we can do about the transformation in Quicklook AR but asked @Felix_Herbst again to get back to you with a more detailed response and maybe there’s a solution.
To give some context, app-less AR on iOS leverages Apple’s QuickLook framework, which does not provide a scripting environment – one needs to work with a limited set of actions and triggers. We wrap and extend the available functionality in our Everywhere Actions, which support both Android and iOS AR.
In practice, many users confirm that with Everywhere Actions and a bit of thinking outside the box a lot of interactions can be expressed.
If you truly need complex interactions on iOS AR, you can combine Needle Engine with tools like Variant Launch that provide a WebXR compatibility layer for iOS – so they add more support for features like JavaScript, but remove compatibility with e.g. VisionOS and other systems.
