  • Method Details

    • countSoftBodies

      public int countSoftBodies()
      Count the soft bodies in this space.
      Returns:
      the count (≥0)

    • getSoftBodyList

      public Collection<PhysicsSoftBody> getSoftBodyList()
      Enumerate soft bodies that have been added to this space and not yet removed.
      Returns:
      a new unmodifiable collection of pre-existing instances (not null)

    • getSoftSpace

      public static PhysicsSoftSpace getSoftSpace()
      Access the PhysicsSoftSpace running on this thread. For parallel physics, this may be invoked from the OpenGL thread.
      Returns:
      the pre-existing PhysicsSoftSpace running on this thread

    • getWorldInfo

      public SoftBodyWorldInfo getWorldInfo()
      Access the parameters applied when soft bodies are added to this space.
      Returns:
      the pre-existing instance (not null)

    • addCollisionObject

      public void addCollisionObject(PhysicsCollisionObject pco)
      Add the specified collision object to this space.
      Overrides:
      addCollisionObject in class PhysicsSpace
      Parameters:
      pco - the collision object to add (not null)

    • contains

      public boolean contains(PhysicsCollisionObject pco)
      Test whether the specified collision object is added to this space.
      Overrides:
      contains in class PhysicsSpace
      Parameters:
      pco - the object to test (not null, unaffected)
      Returns:
      true if currently added, otherwise false

    • countJoints

      public int countJoints()
      Count the joints in this space, including anchors and soft-body joints.
      Overrides:
      countJoints in class PhysicsSpace
      Returns:
      the count (≥0)

    • create

      protected void create()
      Must be invoked on the designated physics thread.
      Overrides:
      create in class PhysicsSpace

    • destroy

      public void destroy()
      Remove all collision objects and physics joints.
      Overrides:
      destroy in class PhysicsSpace

    • getPcoList

      public Collection<PhysicsCollisionObject> getPcoList()
      Enumerate collision objects that have been added to this space and not yet removed.
      Overrides:
      getPcoList in class PhysicsSpace
      Returns:
      a new modifiable collection of pre-existing instances (not null)

    • isEmpty

      public boolean isEmpty()
      Test whether this space is empty.
      Overrides:
      isEmpty in class PhysicsSpace
      Returns:
      true if empty, otherwise false

    • removeCollisionObject

      public void removeCollisionObject(PhysicsCollisionObject pco)
      Remove the specified collision object from this space.
      Overrides:
      removeCollisionObject in class PhysicsSpace
      Parameters:
      pco - the collision object to remove (not null)

    • setGravity

      public void setGravity(Vector3f gravity)
      Alter the gravitational acceleration acting on newly-added bodies.

      Typically, when a body is added to a space, the body's gravity gets set to that of the space. Thus, it is preferable to set the space's gravity before adding any bodies to the space.

      Overrides:
      setGravity in class PhysicsSpace
      Parameters:
      gravity - the desired acceleration vector (not null, unaffected, default=(0,-9.81,0))
