In Ml-Agents GridWorld, where is CollectObservations ?

Hi everyone,
In other examples the agents have CollectObservations() defined, but in GridWorld it doesn’t. I know that it is making decisions based on Camera visualization, but which script does it?
My idea is to create a scene with two targets, one would give more points than the other, but I don’t know where do I put the new prefeb as a new target.
Thanks,
Bruno

Hello. In addition to the `CollectObservations’ method, observations can be collected using sensor components attached to the agent gameobject. If you take a look at the agent gameobject in GridWorld, you will see that it has a Camera sensor attached.
