This environment is part of the <a href='..'>Atari environments</a>. Please read that page first for general information.

|
|
|---|---|
|
|
| Action Space | Discrete(14) |
|
|
| Observation Space | Box(0, 255, (210, 160, 3), uint8) |
|
|
| Import | `gymnasium.make("ALE/KungFuMaster-v5")` |
|

|
|
For more KungFuMaster variants with different observation and action spaces, see the variants section.

## 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.
|
|
|
|
For a more detailed documentation, see [the AtariAge page](https://atariage.com/manual_html_page.php?SoftwareLabelID=268)
|
|
|
|
## Actions
|
|
|
|
KungFuMaster has the action space of `Discrete(14)` with the table below listing the meaning of each action's meanings.
|
|
To enable all 18 possible actions that can be performed on an Atari 2600, specify `full_action_space=True` during
|
|
initialization or by passing `full_action_space=True` to `gymnasium.make`.
|
|
|
|
| Value | Meaning | Value | Meaning | Value | Meaning |
|
|
|---------|-----------------|---------|----------------|---------|--------------|
|
|
| `0` | `NOOP` | `1` | `UP` | `2` | `RIGHT` |
|
|
| `3` | `LEFT` | `4` | `DOWN` | `5` | `DOWNRIGHT` |
|
|
| `6` | `DOWNLEFT` | `7` | `RIGHTFIRE` | `8` | `LEFTFIRE` |
|
|
| `9` | `DOWNFIRE` | `10` | `UPRIGHTFIRE` | `11` | `UPLEFTFIRE` |
|
|
| `12` | `DOWNRIGHTFIRE` | `13` | `DOWNLEFTFIRE` | | |
|
|
|
|
## Observations
|
|
|
|
Atari environments have three possible observation types: `"rgb"`, `"grayscale"` and `"ram"`.
|
|
|
|
- `obs_type="rgb" -> observation_space=Box(0, 255, (210, 160, 3), np.uint8)`
|
|
- `obs_type="ram" -> observation_space=Box(0, 255, (128,), np.uint8)`
|
|
- `obs_type="grayscale" -> Box(0, 255, (210, 160), np.uint8)`, a grayscale version of the "rgb" type
|
|
|
|
See variants section for the type of observation used by each environment id by default.
|
|
|
|
|
|
|
|
## Variants
|
|
|
|
KungFuMaster has the following variants of the environment id which have the following differences in observation,
|
|
the number of frame-skips and the repeat action probability.
|
|
|
|
| Env-id | obs_type= | frameskip= | repeat_action_probability= |
|

|
|
## Difficulty and modes
|
|
|
|
It is possible to specify various flavors of the environment via the keyword arguments `difficulty` and `mode`.
|
|
A flavor is a combination of a game mode and a difficulty setting. The table below lists the possible difficulty and mode values
|
|
along with the default values.
|
|
|
|
| Available Modes | Default Mode | Available Difficulties | Default Difficulty |
|
|
|-------------------|----------------|--------------------------|----------------------|
|
|
| `[0]` | `0` | `[0]` | `0` |

## 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 environments are now in the "ALE" namespace.
|
|
* v4: Stickiness of actions was removed
|
|
