when using a rayperception sensor(2d), if i add additonal observations, the ray perception sensor no longer works.

this is the code i was using

// public override void CollectObservations(VectorSensor sensor)
// {
// sensor.AddObservation(health);
// sensor.AddObservation(totalWood);
// }

when using observations, the agent repeatedly runs into a wall, which it gets -reward for doing.
when not using these observations, it wiggles around normally.

is there a right way to do this?

also, when training 2 agents against eachother (different behaviors, i.e. hide and seek) is it best to use self play here? what about poca vs ppo?

On the behavior parameters Is use child sensors ticked ?
