INSTALLATION

1) Add the following files to your project:


2) Append onto the bottom of your existing Effects.fx file the contents of the following file:



3) Modify iObject.h:

  • Add to Class iObject...
 //added for particle effects / animations
 virtual void update(int now) = 0;
  • At the bottom of the file iObject.h add...
extern "C"
iObject* CreateParticleGenerator(float _generatorlifespan, float _particlelifespan, float _particlespawnrate, float _spawnpositiondispersion,
float _theta, float _startingspeed, Colour _startcolour, Colour _endcolour, float _frequencycolour, float _startsize,
float _endsize, float _frequencysize, Vector _startgravity, Vector _endgravity, float _frequencygravityvertical,
float _frequencygravityhorizontal, float _startalpha, float _endalpha, float _frequencyalpha, Colour* c, float* p);


4) Modify Object.h

  • Add to Class Object...
void update(int now) { /* do nothing, added for particle effects & animations */ }


5) Modify Display.cpp

  • Inside of method: bool Display::setup(void* hwnd)

near line 360 (beneath the comment "// setup successful") add...

ParticleVertex::device = d3dd;
ParticleVertexList::connectDevice(d3dd);


6) Modify Configuration.h

  • Adding into the existing typedef enum Category (line 375) a new type of:
PARTICLES


7) Modify Object.cpp

  • Updating the Object::Object(category, colour, iGraphic*, int, int) method..

Change from..

// store reflectivity, shininess, and texture pointers
material = new Colour[nSubsets];
shine    = new float[nSubsets];
texture  = new iTexture**[nSubsets];
for (int i = 0; i < nSubsets; i++) {
  material[i] = c[i];
  if (p && p[i])
    shine[i] = p[i];
  else
    shine[i] = DEFAULT_SHININESS;
  if (material[i].a != 1.0f)
    category = TRANSLUCENT_OBJECT;
  texture[i] = new iTexture*[nStages];
  for (int j = 0; j < nStages; j++)
    texture[i][j] = NULL;
}

And change it to..:

// store reflectivity, shininess, and texture pointers
material = new Colour[nSubsets];
shine    = new float[nSubsets];
texture  = new iTexture**[nSubsets];
for (int i = 0; i < nSubsets; i++) {
  material[i] = c[i];
  if (p && p[i])
    shine[i] = p[i];
  else
    shine[i] = DEFAULT_SHININESS;
  if (material[i].a != 1.0f && category != PARTICLES)
    category = TRANSLUCENT_OBJECT;
  texture[i] = new iTexture*[nStages];
  for (int j = 0; j < nStages; j++)
    texture[i][j] = NULL;
}


8) Modify DeviceTexture.cpp

  • Inside the method ( void DeviceTexture::create(iScene* scene, const Matrix& view, const Matrix& projection, const Vector& viewpoint) )

Near line 190...

Change from:

d3dd->BeginScene();
scene->draw(SKYBOX);
scene->draw(OPAQUE_OBJECT);   
scene->draw(TRANSLUCENT_OBJECT);
d3dd->EndScene();

And change it to..:

d3dd->BeginScene();
scene->draw(SKYBOX);
scene->draw(OPAQUE_OBJECT);   
scene->draw(TRANSLUCENT_OBJECT);
 scene->draw(PARTICLES);
d3dd->EndScene();


9) Modify Design.cpp

  • Modify void Design::draw()

Changing from:

scene->draw(MIRROR);
scene->draw(SKYBOX);
scene->draw(OPAQUE_OBJECT);
scene->draw(TRANSLUCENT_OBJECT);
hud->draw(HUD_ALPHA);

Changing to:

scene->draw(MIRROR);
scene->draw(SKYBOX);
scene->draw(OPAQUE_OBJECT);
scene->draw(TRANSLUCENT_OBJECT);

scene->draw(PARTICLES);

   hud->draw(HUD_ALPHA);
