ECS Angry Bots sample update or alternative?

I'm looking for a simple but 'complete' hybrid DOTS example to get my head round some real world hybrid basics. ECS Angry Bots looks perfect - except for the fact that it is somewhat out of date.

It would be great if someone could link to a more up-to-date hybrid sample...

...or help me get it to run on the latest DOTS packages?

In terms of updating Angry Bots, I haven't managed to get rid of all the compiler errors yet (using Unity 19.3, Entities 0.11 and related dependencies). So far I've tried:

• World.Active replaced by World.DefaultGameObjectInjectionWorld (or just World where this is available as a property)
• Time.deltaTime replaced by Time.DeltaTime

I'm not sure how best to replace:

• IJobForEachWithEntity<> (e.g. in TimedDestroySystem)
• The second parameter of GameObjectConversionUtility.ConvertGameObjectHierarchy (e.g. in EnemySpawner)

I could probably manage to update inheritance from ComponentSystem to SystemBase etc. as long as I could get it to run in its current form first!

 

Got it to run with the edits mentioned above and using

GameObjectConversionUtility.ConvertGameObjectHierarchy(bulletPrefab, new GameObjectConversionSettings(World.DefaultGameObjectInjectionWorld, GameObjectConversionUtility.ConversionFlags.AddEntityGUID))

for each of the

GameObjectConversionUtility.ConvertGameObjectHierarchy

calls.

 

IJobForEachWithEntity should be replaced with Entities.ForEach for now.
