Sets if this Body can be separated during collisions with other bodies.
When a body is immovable it means it won't move at all, not even to separate it from collision
overlap. If you just wish to prevent a body from being knocked around by other bodies, see
the setPushable method instead.
Optionalvalue: boolean
Whether this body should be immovable (true) or movable (false) during collisions. Default true.
This Game Object.
Provides methods for controlling whether an Arcade Physics Body is immovable during collisions. An immovable body will not be moved or separated when it collides with other bodies, making it ideal for static obstacles, walls, platforms, or any object that should never be displaced by physics interactions. This component is mixed into Game Objects that use Arcade Physics.
