Method Detail

getCollisionDetector

public E3DCollisionDetector getCollisionDetector()

Every bounding object must implement this method that takes a list of E3DLine's and returns the closest collision between any of the lines and the bounding object itself, therefore, it must have a collision detector

Returns:

getParentObject

public E3DCollisionDetectableObject getParentObject()

Bounding objects need to have an actor that they are bounding

Returns:

setParentObject

public void setParentObject(E3DCollisionDetectableObject actor)

Set the parent object of the bounding object. This is normally handled by the engine itself when a bounding object is added to an object (like an actor).

Parameters:

actor -

centerAroundParentObject

public void centerAroundParentObject()

This will automatically set the position of the bounding object to be that of its parent object

onGetClone

public E3DBoundingObject onGetClone()

Returns a clone of the bounding object

Returns:

checkLineIntersectionCollision

public E3DCollision checkLineIntersectionCollision(E3DVector3F startPos,
                                                   E3DVector3F endPos)

Parameters:

startPos - World coordinate start position

endPos - World coordinate end position

Returns:

getOrientation

public E3DOrientation getOrientation()

Every bounding object has an orientation (position/rotation). This is NOT directly related to its parent objects orientation. IE: its not cumulative, this orientation is the actual orientation of the bounding object in the world.

Returns:

scale

public void scale(double scaleAmt)

Scale the bounding object around its position

Parameters:

scaleAmt -

setSize

public void setSize(double size)

Set the size of hte bounding object. If a boundingsphere, the radius will be set to .5(size). If a boundingbox, width, height, and depth will be size.

Parameters:

size - Total size of the bounding object

getSize

public double getSize()

Get the size of the object. This will only be completely accurate for spheres.

Returns:

render

public void render()
