seeAndMoveToEnemy method

void seeAndMoveToEnemy({
  1. required dynamic closeEnemy(
    1. Enemy
    ),
  2. BoolCallback? notObserved,
  3. VoidCallback? observed,
  4. VoidCallback? notCanMove,
  5. double radiusVision = 32,
  6. double? visionAngle,
  7. double? angle,
  8. double margin = 10,
  9. bool runOnlyVisibleInScreen = true,
  10. MovementAxis movementAxis = MovementAxis.all,
})

Checks whether the player is within range. If so, move to it. visionAngle in radians angle in radians. is automatically picked up using the component's direction.
