Create Location-Based AR Quickly and Easily (Unity + Lightship WPS)

Thanks for watching my journey. I want to build the most exciting AR Experiences including games, movies and productive apps. My background is mainly in 2D / 3D Animation using Blender and After Effects, but I always loved the idea auf Augmented Reality. Furthermore I liked to code. So in late 2022 I decided to learn Unity and get deeper into AR Software Development. Let's see how far we can come :)

IMPORTANT ADDITION: 👉🏽 For the seconds part, letting the user place the objects, you can also use the ARWorldPositioningCameraHelper to make your life easier. It will let you automatically access the current GPS coordinates of your camera. The ARWorldPositioningCameraHelper is being automatically attached in play mode to your camera under XR origin when using Lightship WPS . You can simply create a reference to it and then use the latitude and longitudes values from the ARWorldPositioningCameraHelper to spawn the objects. The whole script could look like this: using System.Collections; using System.Collections.Generic; using UnityEngine; using Niantic.Experimental.Lightship.AR.WorldPositioning; using Niantic.Experimental.Lightship.AR.XRSubsystems; using UnityEngine.UI; public class AddWPSObjects : MonoBehaviour { [SerializeField] ARWorldPositioningObjectHelper positioningHelper; [SerializeField] private ARWorldPositioningManager _positioningManager; [SerializeField] private Button button; //Add some random materials [SerializeField] private List cubeMaterials; //Reference the helper private ARWorldPositioningCameraHelper _arWorldPositioningCameraHelper; void Start() { //Find the helper in the scene _arWorldPositioningCameraHelper = FindObjectOfType(); button.onClick.AddListener(SpawnObjectAtPosition); _positioningManager.OnStatusChanged += OnStatusChanged; } private void OnStatusChanged(WorldPositioningStatus obj) { Debug.Log("WPS Status Changed " + obj); } void SpawnObjectAtPosition() { //Use it to determine the GPS position double latitude =_arWorldPositioningCameraHelper.Latitude; double longitude = _arWorldPositioningCameraHelper.Longitude; double altitude = 0.0; GameObject cube = GameObject.CreatePrimitive(PrimitiveType.Cube); cube.GetComponent().material = cubeMaterials[Random.Range(0, cubeMaterials.Count-1)]; cube.transform.localScale *= .75f; positioningHelper.AddOrUpdateObject(cube, latitude, longitude, altitude, Quaternion.identity); Debug.Log("Placing Object at: latitude:" + latitude + " longitude: " + longitude); } }

Assets\PreplaceWorldObjects.cs(36,34): error CS0246: The type or namespace name 'ARWorldPositioningStatus' could not be found (are you missing a using directive or an assembly reference?) I have this error when i try implementing the first script. WHat could be the cause

[@user-xn7yt3oy7z]

Thanks for the tutorial! I tried this, but only the second script works properly. I want to pre-place some objects though. I have no errors, but the objects still don't appear on the device. However, when I playtest in Unity, the debug.log statements seem to work well (Placing object at longitude X and latitude Y appear). A bit late, but any suggestions?

[@AliveStudios_]

Hi mate :) So if I get you right, pre-placing objects does not work for you, because the 3D Objects do not appear at their corresponding positions on device? Did you make sure to set in the Camera settings 14:08 the clipping plane option to 500, or even better something like 10.000 ?

[@user-xn7yt3oy7z]

@@AliveStudios_ Hi, thanks for taking the time to reply! I had already set the clipping planes to 10000. My problem is that I am not sure if the loop that spawns the object actually works, because on the android device, the only log that appears is the: Status changed to available. When I run the game on Unity however, the game window shows the following logs: -Status changed to initializing. -[Warning] Package “Lightship World Positioning System (WPS) Plugin" has no loader metadata. Skipping loader initialization. (I saw on the site for ARDK 3.6 Release notes that this error is benign and can be ignored, so I am not sure if that’s the issue). However, in the editor window in Unity, the following debug statements appear: -Added object at latitude X and longitude Y. -Status changed to initializing. -Plugin Lightship World Positioning System (WPS) Plugin" has no loader metadata. Skipping loader initialization.

So i tried this and added the zlog as nothing was appearing, I've checked all the permissions etc, but im getting the error no tracking and no gnss. Any ideas?

[@AliveStudios_]

hmm, so if you made sure that you have a good 4G / 5G on your phone it should usually work. Is there any way you can try this on another phone and see if you got the same error?

[@raizel420]

is it possible to create a game using your tutorial in tiktok effect house?

[@AliveStudios_]

Hey :) So this Tutorial can be used to create a standalone game for the play store or App Store, which you could probably advertise on your TikTok account . While it is also possible to create games in effect house , as far as I am concerned, it is not possible to create AR games.

Hi sir sorry for bothering may I know how to set the aspect ratio into iphone? because I search google I just cant search it....

[@AliveStudios_]

Hey mate :) It is not necessary to set it to iPhone, you can also set it to any android phone you like :). Most likely you do not see iPhone as your build target is set to Android
