Inconsistent distance for same moving commands.

I’ve tried the following code and it plots images with different distance to a next door. OS: Windows 10.

for i in range(10):
    env.seed(8)
    env.floor(1)
    obs = env.reset()

    for _ in range(20):
        obs, reward, done, info = env.step([1, 0, 0 ,0])

    plt.figure(figsize=(3,3))
    plt.imshow(obs[0])
    plt.show()

Hi @mortido and @seungjaeryanlee

Thanks to both of you for doing this investigation. I have been able to reproduce similar results myself. Especially your recent post @mortido leads me to believe this inconsistency is due to some aspect of the environment not being completely reset on reset. I will look into this and make sure it is resolved before the launch of the contest on Feb 11.

Hi all,

We just pushed a new release and binary (v1.1). This includes a fix for resetting the character animator between floors and resets. This should result in much more reproducible behavior between floors. It still won’t be 100% due to inherent indeterminism in the Unity physics, but it is no longer nearly as extreme as shown above, and we believe within an acceptable range.

Thanks again to those who pointed this out.
