    • PhysicsCharacter

      public PhysicsCharacter(CollisionShape shape, float stepHeight)
      Parameters:
      shape - The CollisionShape (no Mesh or CompoundCollisionShapes)
      stepHeight - The quantization size for vertical movement

  • Method Details

    • buildObject

      protected void buildObject()

    • warp

      public void warp(Vector3f location)
      Sets the location of this physics character
      Parameters:
      location - the desired physics location (not null, unaffected)

    • setWalkDirection

      public void setWalkDirection(Vector3f vec)
      Set the walk direction, works continuously. This should probably be called setPositionIncrementPerSimulatorStep. This is neither a direction nor a velocity, but the amount to increment the position each physics tick. So vector length = accuracy*speed in m/s
      Parameters:
      vec - the walk direction to set

    • getWalkDirection

      public Vector3f getWalkDirection()
      Returns:
      the currently set walkDirection

    • setUpAxis

      public void setUpAxis(int axis)

    • getUpAxis

      public int getUpAxis()

    • setFallSpeed

      public void setFallSpeed(float fallSpeed)

    • getFallSpeed

      public float getFallSpeed()

    • setJumpSpeed

      public void setJumpSpeed(float jumpSpeed)

    • getJumpSpeed

      public float getJumpSpeed()

    • setGravity

      public void setGravity(float value)
      Alter the character's gravitational acceleration without altering its "up" vector.
      Parameters:
      value - the desired downward acceleration (in physics-space units per second squared, default=29.4)

    • getGravity

      public float getGravity()

    • setMaxSlope

      public void setMaxSlope(float slopeRadians)

    • getMaxSlope

      public float getMaxSlope()

    • setContactResponse

      public void setContactResponse(boolean newState)
      Enable/disable this body's contact response.
      Parameters:
      newState - true to respond to contacts (default=true)

    • isContactResponse

      public boolean isContactResponse()
      Test whether this body responds to contacts.
      Returns:
      true if responsive, otherwise false

    • onGround

      public boolean onGround()

    • jump

      public void jump()

    • setCollisionShape

      public void setCollisionShape(CollisionShape collisionShape)
      Description copied from class: PhysicsCollisionObject
      Sets a CollisionShape to this physics object, note that the object should not be in the physics space when adding a new collision shape as it is rebuilt on the physics side.
      Overrides:
      setCollisionShape in class PhysicsCollisionObject
      Parameters:
      collisionShape - the CollisionShape to set

    • setPhysicsLocation

      public void setPhysicsLocation(Vector3f location)
      Set the physics location (same as warp())
      Parameters:
      location - the location of the actual physics object

    • getPhysicsLocation

      public Vector3f getPhysicsLocation(Vector3f trans)
      Parameters:
      trans - storage for the result (modified if not null)
      Returns:
      the physicsLocation

    • getPhysicsLocation

      public Vector3f getPhysicsLocation()
      Returns:
      the physicsLocation

    • setCcdSweptSphereRadius

      public void setCcdSweptSphereRadius(float radius)

    • setCcdMotionThreshold
