public abstract class MobileObject
extends SpaceObject
```
A MobileObject is a SpaceObject that can simulate continuous movement through its SpaceState's space. If a MobileObject has had Cell2D's standard collision mechanics enabled for it, this movement will be blocked by any solid surfaces of SpaceObjects in the MobileObject's path.

A MobileObject may have a collision Hitbox that represents it for purposes of colliding with solid surfaces. The collision Hitbox's rectangular bounding box, rather than its exact shape, is what represents the MobileObject in Cell2D's standard collision mechanics, and thus standard collision only handles interactions between rectangular shapes. A MobileObject with no collision Hitbox cannot collide with solid surfaces, even if collision is enabled for it.

A MobileObject may have a pressing angle that causes it to press against and collide with solid surfaces in the angle's direction during movement, as long as it is touching them and not moving away from them. The pressing angle is specified as relative (to the MobileObject's flipped status and angle of rotation) or absolute.

A MobileObject may have one or more MobileObject followers, and if it does, it is called its followers' leader. When a MobileObject moves, all of its followers automatically move to maintain their relative positions to it. A MobileObject cannot collide with its leader, super-leaders, followers, or sub-followers.

A MobileObject has a velocity, as well as a vector called a step that acts as a short-term adjustment to its velocity, both in fracunits per time unit, and both of which are initially (0, 0). Every frame, between the periods in which its SpaceState's SpaceThinkers perform their beforeMovementActions() and their frameActions(), a MobileObject assigned to an active SpaceState moves by the sum of its velocity and step multiplied by its time factor, then resets its step to (0, 0). A MobileObject's movement priority (0 by default) determines when it will move relative to other MobileObjects. MobileObjects with higher movement priorities move before those with lower ones. Also, if two solid MobileObjects would otherwise collide with each other, the one with the higher movement priority will push the other one along with it.

Every time a MobileObject moves, it records the SpaceObjects whose solid surfaces it collided with and the Directions of the surfaces relative to it when it collided with them, as well as its total displacement over the course of the movement, not counting pushes from moving solid surfaces or manual manipulation of its position. These records are reset when the MobileObject moves again, or when it is removed from the SpaceState whose space the records reflect.
