Description#
You are a Kung-Fu Master fighting your way through the Evil Wizard’s temple. Your goal is to rescue Princess Victoria, defeating various enemies along the way. Detailed documentation can be found on the AtariAge page.
Actions#
By default, all actions that can be performed on an Atari 2600 are available in this environment. However, if you use v0 or v4 or specify full_action_space=False during initialization, only a reduced number of actions (those that are meaningful in this game) are available. The reduced action space may depend on the flavor of the environment (the combination of mode and difficulty). The reduced action space for the default flavor looks like this:
Num |

Observations#
By default, the environment returns the RGB image that is displayed to human players as an observation. However, it is possible to observe
The 128 Bytes of RAM of the console
A grayscale image
instead. The respective observation spaces are
Box([0 ... 0], [255 ... 255], (128,), uint8)Box([[0 ... 0] ... [0 ... 0]], [[255 ... 255] ... [255 ... 255]], (250, 160), uint8)
respectively. The general article on Atari environments outlines different ways to instantiate corresponding environments
via gymnasium.make.
Arguments#
env = gymnasium.make("ALE/KungFuMaster-v5")
The various ways to configure the environment are described in detail in the article on Atari environments.

You may use the suffix “-ram” to switch to the RAM observation space. In v0 and v4, the suffixes “Deterministic” and “Noframeskip”
are available. These are no longer supported in v5. In order to obtain equivalent behavior, pass keyword arguments to gymnasium.make as outlined in
the general article on Atari environments.
The versions v0 and v4 are not contained in the “ALE” namespace. I.e. they are instantiated via gymnasium.make("KungFuMaster-v0")
Version History#
A thorough discussion of the intricate differences between the versions and configurations can be found in the general article on Atari environments.
v5: Stickiness was added back and stochastic frameskipping was removed. The entire action space is used by default. The environments are now in the “ALE” namespace.
v4: Stickiness of actions was removed
v0: Initial versions release (1.0.0)
