When the player is present, the entity.animstate is set to actionfrequency[0] when the distance between this and the player is less than the wanderradius, it is set to actionfrequency[1] otherwise.

Frequency meaning

Each of the 2 frequencies corresponds to an animstate to set the entity depending on the distance between it and the player in regards to the wanderradius. The first one applies when the distance is strictly lower than the wanderradius and the second one applies otherwise.

NOTE: this behavior does NOT read the frequency passed in DoBehavior

DoBehavior

If the player isn't present, this does nothing.

Otherwise, if the distance between this entity and the player is less than the wanderradius, the entity animstate is set to actionfrequency[0]. it is set to actionfrequency[1] otherwise.
