RainbowEffect类 参考

类 RainbowEffect 继承关系图:

RainbowEffect 的协作图:

Public 成员函数
bool	init () override
virtual bool	initWithTotalParticles (int numberOfParticles) override
virtual void	update (float dt) override

详细描述

在文件 ParticleTest.cpp 第 1382 行定义.

成员函数说明

init()

bool RainbowEffect::init ( )

override

在文件 ParticleTest.cpp 第 1390 行定义.

{
    return initWithTotalParticles(150);
}

引用了 initWithTotalParticles().

函数调用图:

initWithTotalParticles()

bool RainbowEffect::initWithTotalParticles ( int  numberOfParticles )

overridevirtual

在文件 ParticleTest.cpp 第 1395 行定义.

{
    if( ParticleSystemQuad::initWithTotalParticles(numberOfParticles) )
    {
        // additive
        setBlendAdditive(false);
 
        // duration
        setDuration(ParticleSystem::DURATION_INFINITY);
 
        // Gravity Mode
        setEmitterMode(ParticleSystem::Mode::GRAVITY);
 
        // Gravity Mode: gravity
        setGravity(Vec2(0.0f,0.0f));
 
        // Gravity mode: radial acceleration
        setRadialAccel(0);
        setRadialAccelVar(0);
 
        // Gravity mode: speed of particles
        setSpeed(120);
        setSpeedVar(0);
 
 
        // angle
        setAngle(180);
        setAngleVar(0);
 
        // emitter position
        auto winSize = Director::getInstance()->getWinSize();
        setPosition(Vec2(winSize.width/2, winSize.height/2));
        setPosVar(Vec2::ZERO);
 
        // life of particles
        setLife(0.5f);
        setLifeVar(0);
 
        // size, in pixels
        setStartSize(25.0f);
        setStartSizeVar(0);
        setEndSize(ParticleSystem::START_SIZE_EQUAL_TO_END_SIZE);
 
        // emits per seconds
        setEmissionRate(getTotalParticles()/getLife());
 
        // color of particles
        setStartColor(Color4F(Color4B(50, 50, 50, 50)));
        setEndColor(Color4F(Color4B(0, 0, 0, 0)));
 
        _startColorVar.r = 0.0f;
        _startColorVar.g = 0.0f;
        _startColorVar.b = 0.0f;
        _startColorVar.a = 0.0f;
        _endColorVar.r = 0.0f;
        _endColorVar.g = 0.0f;
        _endColorVar.b = 0.0f;
        _endColorVar.a = 0.0f;
 
        setTexture(Director::getInstance()->getTextureCache()->addImage("Images/particles.png"));
        return true;
    }
 
    return false;
}

被这些函数引用 init() , 以及 Issue1201::onEnter().

这是这个函数的调用关系图:

update()

void RainbowEffect::update ( float  dt )

overridevirtual

在文件 ParticleTest.cpp 第 1461 行定义.

{
    _emitCounter = 0;
    ParticleSystemQuad::update(dt);
}
