C++ (Cpp) shared_ptr::GetAlpha Examples

Example #1

File: Affectors.cpp Project: Krozark/SFML-Modules-sup

	void CFadeOutAffector::Update(boost::shared_ptr<CParticle> &particle, math::float32 dt)
	{
		if(particle->GetLiveTime()-mFadeTime < 0.f)
		{
			math::float32 alpha = particle->GetAlpha() - (particle->GetAlpha()/particle->GetLiveTime())*dt;
			particle->SetAlpha(alpha);
			if(this->mMinAlpha > alpha)
				particle->SetAlpha(mMinAlpha);
		}
	}

Example #2

	{
		math::float32 alpha_beg = particle->GetAlpha();
		if(/*particle->GetStartLiveTime()-mFadeTime < particle->GetLiveTime()*/particle->GetAlpha() < mMaxAlpha)

			particle->SetAlpha(particle->GetAlpha() + alpha);
			if(particle->GetAlpha() > mMaxAlpha)
				particle->SetAlpha(mMaxAlpha);
