Sensing¶

Active tracking¶

An actor can track down whether he is at his position or before other actors and so on.

This can be done with the following function, for example:

actor.sensing_tokens(distance, token)

The function detects whether there are actors at the current position of the actor (or distance steps forward). If so, they are returned as a list, otherwise None is returned.

Example¶

The example checks whether the actor is standing in front of a locked door:

actors_in_front = self.sensing_tokens(distance = 1, token = door)
        if self.board.door in actors_in_front:
            if self.board.door.closed:
                message = "The Door is closes"

Sensing via event methods¶

Alternatively, you can also implement event methods: The on_sensing_xy method is called every time an actor detects something.
