* For DPS905, Professor Chris Szalwinski

**************************************************************************************************

[[Image:Kaitlyn_particles_April2011_v01.jpg]]

* [http://matrix.senecac.on.ca/~dacallow/DPS905/ParticleVertexList.cpp ParticleVertexList.cpp]

* [http://matrix.senecac.on.ca/~dacallow/DPS905/ParticleVertexList.h ParticleVertexList.h]

~~(OPTIONAL)~~* A Optionally, you can get a simple texture for you to try making particle effects with * here: [http://matrix.senecac.on.ca/~dacallow/DPS905/bubble.tga bubble.tga]

5) Modify Display.cpp

* ~~Inside~~ Add an include at the top.. #include "ParticleVertexList.h" // for access to ParticleVertexList::connectDevice() * Then add inside of the method: bool Display::setup(void* hwnd)

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

'''scene->draw(PARTICLES);'''

hud->draw(HUD_ALPHA);

10) Modify iVertexList.h

* Add to Class iVertexList

virtual void clear() = 0;

* Add to the bottom of the file iVertexList.h

extern "C"

iVertexList* CreateParticleVertexList(PrimitiveType t, int np, bool flip = false);

11) Modify VertexList.h

* Add to Class VertexList

void clear() {nVertices = 0;} /* added for particle effects */

* At the bottom of VertexList.h add to the Class StockMesh

void clear() {}

== [B] - HOW TO USE ==

To create a particle:

# 1) Include in ParticleGenerator.h# 2) Use the following suggested code(maybe in Design.cpp inside Design::initialize(int now)):

//VARIABLES

~~iParticleGenerator~~iObject* particleEffect1 = CreateParticleGenerator(generatorlifespan, particlelifespan, particlespawnrate, spawndispersion, theta, startingspeed, startcolour, endcolour, frequencycolour, startsize, endsize, frequencysize, startgravity, endgravity, frequencygravityvertical, frequencygravityhorizontal, startalpha, endalpha, frequencyalpha, &c, &p);

//Add your desired texture on

particleEffect1->attach(particle_texture,0);

//Position your particlegenerator

particleEffect1->translate(250,70,250);

//((ParticleGenerator*)particleEffect1)->AttractTo(someObject,250.0f);

//((ParticleGenerator*)particleEffect1)->AttractTo(&Vector(50,50,50),250.0f);

3) Add inside Design.cpp in the Design::Update(int now) method your particle generator's update method.

particleEffect1->update(now);

'''PLEASE NOTE:''' The following is not working / implemented at this time: frequency, alpha transparency
