ArcGIS Unity Mesh Colliders
Hi, I am currently having a few issues with the generated ArcGIS mesh colliders. I have a few gameobjects in my scene with rigidbody enabled and gravitational force acted upon them. There are a number of issues that I have found while experimenting with this.
To begin with, on startup the gameobjects will fall straight through the map since the tilles has not loaded in yet. I have tried to solve this issue by implementing a wait function. See below, where after the ArcGIS map is created I call this coroutine. This does not solve it though, since the ArcGISLoadStatus is changed to loaded almost immediatly while all of the visible tiles are still loading in. Is there anyway to wait until a certain amount of tiles have been rendered? Or do you have to for example wait for a hardcoded time X seconds until the tiles have loaded? (I have tried this and it worked okay ish, but it does not seem optimal)
Another Issue I found is when you unload the tiles, with it also mesh colliders are unloaded so the gameobjects will fall through the map. How would one go about solving this issue? Should you have "pre-baked" mesh colliders for the entire world (will most likely have a heavy impact on performance)? Or shall one disable the physics when the objects are not visible?
Thankful for any advice or help!
Hi again, I have been trying this approach with minimal success by raycasting in the direction of the gravitational force. The main issue is in regards to when the tiles changes LOD, also the mesh colliders change. Which causes the gameobjects to sort of glitch through the map. Also, on startup I get hits on the mesh colliders and still falls through the colliders, this may have also to do with the LOD. I could solve this issue by placing the objects high enough, which gives the tiles enough time to fully load in.I think it would have been useful if you were able to determine the tiles LOD based on either the layer or tag.
