HelloWorld.cpp

	m_pBgSprite = Sprite::create("img_dating.png");
	//m_pBgSprite->setFlippedX(true);
	//m_sBgSize = m_pBgSprite->getContentSize();
	float waveSpeed = 0.3f;
	auto gp = GLProgram::createWithFilenames("maskBlend.vert", "maskBlend.frag");
	auto state = GLProgramState::create(gp);
	state->setUniformFloat("_distanceFactor", 300);
	state->setUniformFloat("_timeFactor", -30.0);
	state->setUniformFloat("_totalFactor", 0.01);
	state->setUniformFloat("_waveWidth", 0.5);
	state->setUniformFloat("_curWaveDis", 0);
	state->setUniformVec2("_startPos", Vec2(0.5,0.5));
	m_pBgSprite->setGLProgramState(state);
	m_pBgSprite->setPosition(Vec2(visibleSize.width / 2 , visibleSize.height / 2));
	addChild(m_pBgSprite);
