Discrete action space implementation based on BaseRLAviary

[Konjak2e8]

I'm trying to customize a multi-drone RL environment with a discrete action space - specifically, drones can only fly in some certain directions in a fixed velocity - and I failed to find the way to define a discrete action space, nor can I find an example in the doc on branch master.
Is there any solution to build a discrete action space based on BaseRLAviary?

Hi @Konjak2e8

for your use case, I would build on top of VelocityAviary, where the input is a 4 dimensional vector (a reference direction + a reference magnitude speed) and look into Farama's docs to replace the Box (n-array/tensor) input for a Discrete one https://gymnasium.farama.org/api/spaces/
