Getting an error when using the gymnasium env checker

[Cornslakes]

Describe the bug
It is not possible to use the gymnasium env_checker on the environment.

To Reproduce
Steps to reproduce the behavior:

`from gymnasium.utils.env_checker import check_env
from stable_baselines3.common.env_checker import check_env

env modifications if needed

GAMEOVER_PENALTY = 75
MISSED_COIN_PENALTY = 3

DODGED_OBSTACLE_REWARD = 1
COLLECTED_COIN_REWARD = 12

def create_env():
env = VectorVelocityEnv()
env.coin_missed_penalty = MISSED_COIN_PENALTY
env.game_over_penalty = GAMEOVER_PENALTY
env.dodged_obstacle_reward = DODGED_OBSTACLE_REWARD
env.coin_reward = COLLECTED_COIN_REWARD
return env

env = create_env()
check_env(env)`

Expected behavior
The code should run properly.

Desktop (please complete the following information):

• OS: Windows 11
• Python Version: 3.10.11
• VectorVelocity Version: 0.1.0

Thanks for sharing that bug. It seems like it's related to Gymnasium's options parameter in the step function. As a workaround, the Stable Baselines3 check_env function can be used. The fix for this bug will be provided in the next release.

sample workaround

from stable_baselines3.common.env_checker import check_env
from gym_vectorvelocity import VectorVelocityEnv

GAMEOVER_PENALTY = 75
MISSED_COIN_PENALTY = 3

DODGED_OBSTACLE_REWARD = 1
COLLECTED_COIN_REWARD = 12

def create_env():
    env = VectorVelocityEnv()
    env.coin_missed_penalty = MISSED_COIN_PENALTY
    env.game_over_penalty = GAMEOVER_PENALTY
    env.dodged_obstacle_reward = DODGED_OBSTACLE_REWARD
    env.coin_reward = COLLECTED_COIN_REWARD
    return env

env = create_env()
check_env(env)
