geBoundingBox represents a 2D bounding box on the 3D axis. The box contains four float2 points in a array called pos[], as well as a float y which keeps track of the height of the box. The box itself lies on the (X,Z) plane.

Reference

Fields

•  float2 pos[4]

•  float y

Constructors

There are four constructors for geBoundingBox. The first two take in points and build a box at the points specified. The order of points is top left, top right, bottom right, bottom left. The second constructor takes in an array of 4 points. The third constructor builds a box around a (x,z) center point, with a length, width and height specified. The fourth builds a box around a 3D (x,y,z) center point and a length and width.

•  geBoundingBox( float2 one, float2 two, float2 three, float2 four, float inZ )

•  geBoundingBox( float2 inPos[], float InZ )

•  geBoundingBox( float2 center, float length, float width, float depth )

•  geBoundingBox( float3 center, float length, float width )

Accessors

Note: setPos is for changing an entire pos array, while setPosAt is for one point.

•  float getY()

•  float2 getElement( const int at )

•  void setZ( const float inZ )

•  void setPos( float2 pos[] )

•  void setPosAt( float2 in, const int at )

Methods

Note: The intersects functions are for detecting intersections between either two boxes or a sphere and box. pointIntersect functions help with the intersect functions and are used internally.

•  bool Intersects( geBoundingBox that ) const

•  bool Intersects( geBoundingSphere that ) const

•  bool pointIntersect( geBoundingBox that ) const

•  bool pointIntersect( float2 extends[] ) const

•  bool pointIntersect( float2 point ) const
