Modifying the Object3d Class
Next, we have to add some code to our Object3d class, so it can use the explosions.
The MAX_EXPLOSIONS variable holds the maximum number of explosions associated with this object.
private int MAX_EXPLOSIONS = 3;
The m_NumberExplosions variable holds the actual number of explosions associated with this object.
private int m_NumberExplosions = 0;
The m_Explosions variable holds references to the SphericalPolygonExplosion objects associated
with this object, if any.
private SphericalPolygonExplosion[] m_Explosions = new SphericalPolygonExplosion[MAX_EXPLOSIONS];
We also add the functions RenderExplosions() , to render explosions; UpdateExplosions() , to
update explosions; and ExplodeObject() , to start explosions. These functions are fairly simple,
so in the interest of saving space, please refer to the Source Code/Download area for this chapter
at apress.com for the full details.
The DrawObject() function must be modified to render the explosions, by calling the
RenderExplosions() function. (See Listing 7-50.)
