Is there 2D example environment ?

Is there a 2D environment example that we can use like this? I really dont need one more dimension for this example and it will only add complexity to my problem

 

Out of curiosity is there anything in particular you're looking for in a 2D environment?
Ray Perception Sensor 2D, or your own vector observations from raycast should work just fine. From the point of view of the agent I would even argue that a lot of the environments in the examples are 2D (only 'horizontal' actions and observations). How the engine renders it is secondary, unless I'm missing something distinctive to 2D games here.

 

Thanks @andrzej_ , you are right in a way that the physics and frame rendering of the Unity engine take place asynchronously. As such it is possible to run Unity simulations without rendering if it is not critical to the simulation (Unity: A General Platform for Intelligent Agents). However I think it adds up complexity just having a one more dimension while training the agent. I will start with 3D food collecter environment for this purpose, than I will see

 

Thank you, I will try =) !
