Hey everyone,
I’m currently trying to track down a crash somewhere around Unity.Entities.EntityComponentStore.InstantiateEntitiesOne:

This error happens in like 1/20 or so scene changes and might possibly be related to me destroying the entire default world and recreating it? So maybe an ECB is running on a disposed world.
This is the code I’m using:
public static IEnumerator DestroyAndCreateDefaultWorld() {
/* Destroy the default world: */
var defaultWorld = World.DefaultGameObjectInjectionWorld;
var entityManager = defaultWorld.EntityManager;
entityManager.CompleteAllJobs();
/* Destroy */
entityManager.DestroyEntity(entityManager.UniversalQuery);
yield return new WaitForEndOfFrame();
/* Disable all systems: */
foreach (var system in defaultWorld.Systems) {
system.Enabled = false;
}
yield return new WaitForEndOfFrame();
/* Actually dispose of the world: */
defaultWorld.Dispose();
/* Take it out of the player loop: */
ScriptBehaviourUpdateOrder.RemoveWorldFromCurrentPlayerLoop(defaultWorld);
/* Reinitialize the default world: */
DefaultWorldInitialization.Initialize("Default World");
}
Again, not sure if it’s related to the crash even, but I figured I’d add the snippet.
This has worked without a hitch during many many hours of debugging and testing in the editor, but in the Android player it will crash about 5% of the time.
Anyone has a clue on how to approach this?
Thanks,
Nico
