I started building an Android and iOS AR application with image tracking. The goal is to build a plane with a material on it based on the space between 4 trackable images. So my system should detect and store four image trackers and create Emptys at their locations. With these GameObjects, a custom written Mesh Pipeline should triangulate a plane scaled to these four trackers. I am currently trying to create and store the Emptys but dont really know how to debug my code in Unity since I have to run it on my phone and I'm not shure if my code works well. Based on the AR Tracked Image Manager from Unity in the following class I used the basics which I found in the documentation (OnEnable, OnDisable and OnChanged). In the OnChanged Method I implemented the handling if a new Image is tracked that the GameObject is build and the Entry in the List is done. Update and Remove are also in here. I don't know if this is the correct workflow after the ARTrackedImageManager. Thanks for your help!
