Regression: getState will now return nullptr/null/None if game is in the terminal state.

We need terminal states.

Why do you need them?

Our codes assumes there is a terminal state, cf. OpenAI gym environments and their Universe framework.

But you can add a simple condition on that, don't you? The problem is there is physically no data on the terminal state in Doom.

We could return a zeros array or something like that but we require an observation - even if it is a dummy observation.

As I remember (in the few instances I did die in Doom, ;-)) the camera was still active even after dying. We should be able to capture a frame even when the player health is zero? This must be a limitation in ViZDoom rather than in the underlying ZDoom engine.

At this point, 100% it won't be changed in the original API, closing.
