1.10.02 - Random movement

This type of movement is a rectilinear movement whose trajectory changes randomly over time. It can be seen as a particular case of the straight movement type, where the angle is automatically changed after random delays.

Methods inherited from movement

Random movements are particular movement objects. Therefore, they inherit all methods from the type movement.

See Methods of all movement types to know these methods.

Methods of the type random movement

The following methods are specific to random movements.

random_movement:get_speed()

Returns the speed applied to this movement when it is started.

random_movement:set_speed(speed)

Sets the speed applied to this movement when it is started.

random_movement:get_angle()

Returns the angle of the current trajectory in radians.

East is 0, North is math.pi / 2, West is math.pi, South is 3 * math.pi / 2 and any intermediate value is possible.

Remarks
If you prefer a value in a 4-direction system, see movement:get_direction4().

random_movement:get_max_distance()

Returns the maximum distance of this movement.

If the movement goes further than this distance, it automatically comes back towards the initial position.

random_movement:set_max_distance(max_distance)

Sets the maximum distance of this movement.

If the movement goes further than this distance, it automatically comes back towards the initial position.

random_movement:is_smooth()

Returns whether this movement adjusts its trajectory when an obstacle of the map is reached. This property has no effect if the movement is not attached to a map entity or if the movement ignores obstacles.

random_movement:set_smooth([smooth])

Sets whether this movement should adjust its trajectory when an obstacle of the map is reached. This property has no effect if the movement is not attached to a map entity or if the movement ignores obstacles.

Events inherited from movement

Random movements are particular movement objects. Therefore, they inherit all events from the type movement.

See Events of all movement types to know these events.
