Rewarding an agent when it "sees" something

Hello

I am trying to teach an agent to find a target but once it has "seen" the target, I want to give it a reward.

I am using ray cast perception and I was wondering if there was any where to access the ray cast hit information shown in this script https://github.com/Unity-Technologi...ntime/Sensor/RayPerceptionSensor.cs#L211-L216 such that when a ray has hit an object of interest, I can reward the agent immediately.

Any help is gladly appreciated. Thank you!

 

Hey! I am trying to do the same thing, please say if you figured it out

 

The easiest way to do that is to use the

Detectable Tags

list on the RayPerceptionSensor and just tag your target objects. Walkthrough. Documentation.

 

If tagging does not fit your use case then this post may help - https://forum.unity.com/threads/how-to-get-rayperceptionsensor-values.1010440/#post-6595081

 

Thanks Luke. Actually, my original goal was to collect observations for imitation learning and I found out that it can be done neatly with Demonstrations.
