Method CollectObservations
CollectObservations(VectorSensor)
Implement CollectObservations() to collect the vector observations of
the agent for the step. The agent observation describes the current
environment from the perspective of the agent.
Declaration
public virtual void CollectObservations(VectorSensor sensor)Parameters
| Type | Name | Description |
|---|---|---|
| VectorSensor | sensor | The vector observations for the agent. |
Remarks
An agent's observation is any environment information that helps the agent achieve its goal. For example, for a fighting agent, its observation could include distances to friends or enemies, or the current level of ammunition at its disposal.
You can use a combination of vector, visual, and raycast observations for an
agent. If you only use visual or raycast observations, you do not need to
implement a CollectObservations() function.
Add vector observations to the sensor parameter passed to
this method by calling the VectorSensor helper methods:
- AddObservation(int)
- AddObservation(float)
- AddObservation(Vector3)
- AddObservation(Vector2)
- AddObservation(Quaternion)
- AddObservation(bool)
- AddObservation(IList<float>)
- AddOneHotObservation(int, int)
You can use any combination of these helper functions to build the agent's
vector of observations. You must build the vector in the same order
each time CollectObservations() is called and the length of the vector
must always be the same. In addition, the length of the observation must
match the VectorObservationSize
attribute of the linked Brain, which is set in the Editor on the
Behavior Parameters component attached to the agent's GameObject.
