Enum Values
public static final ShapeMotion DYNAMIC
Dynamic shapes are fully simulated in the physics simulation. They have non-zero mass, move according to forces, and can collide with all other shape types (static, dynamic, and kinematic).
public static final ShapeMotion KINEMATIC
Kinematic shapes move under the physics simulation according to their velocity but do not respond to forces. They behave as if they have infinite mass. Kinematic shapes do not collide with static shapes or other kinematic shapes, but they can be involved in collisions with dynamic shapes.
An example of a kinematic shape in a game would be a moving platform that slides back and forth in a predetermined way.
public static final ShapeMotion STATIC
Static shapes do not move under the physics simulation, behave as if they have infinite mass, and have zero velocity. Static shapes also do not collide with other static or kinematic shapes, but they can be involved in collisions with dynamic shapes.
In a game, for example, static shapes are best used to represent things like the ground, walls, and other immovable, impenetrable obstacles.
This is the default motion type for newly created shapes.
