Available actions

The available actions using the agent_host.SendCommand() command (See: demo.ipynb) are the following:
move: walks forwards/backward
0 -> Nothing, 1 -> Forward, -1 -> Backwards
strafe: walks left/right
0 -> Nothing, 1 -> Right, -1 -> Left
turn: turns the camera left/right without moving
0 -> Nothing, 1 -> Right, -1 -> Left

Examples:

Example commands using the low-level actions
env.agent_host.sendCommand("turn 1")
env.agent_host.sendCommand("strafe -1")
env.agent_host.sendCommand("move 0")

High-level actions

These actions are implemented in the step() function of the MalmoMazeEnv class. Right now the move 1, turn 1, and turn -1 actions are used.
I recommend including two strafe commands and move 0.

Update 1

I added the option to modify the action space in the yml file. I played around with this configuration:

  0: move 0  # don't move
  1: move 1  # move forward
  2: move -1  # move backward
  3: strafe 1  # move right
  4: strafe -1  # move left
  5: turn 1  # turn right
  6: turn -1  # turn left

I found out that the move 0 command is very slow and I think that will impact the training. For now, I'm removing the move 0 action.
