C++ (Cpp) StelCore::getTimeRate Examples

Example #1

File: MeteorMgr.cpp Project: incadoi/stellarium

void MeteorMgr::update(double deltaTime)
{
#ifdef _MSC_BUILD
	return;
#endif
	if (!flagShow)
		return;
	
	deltaTime*=1000;
	StelCore* core = StelApp::getInstance().getCore();

	// step through and update all active meteors
	for (std::vector<Meteor*>::iterator iter = active.begin(); iter != active.end(); ++iter)
	{
		if (!(*iter)->update(deltaTime))
		{
			// remove dead meteor
			//      qDebug("Meteor \tdied\n");

			delete *iter;
			active.erase(iter);
			iter--;  // important!
		}
	}

	// only makes sense given lifetimes of meteors to draw when timeSpeed is realtime
	// otherwise high overhead of large numbers of meteors
	double tspeed = core->getTimeRate()*86400;  // sky seconds per actual second
	if (tspeed<=0 || fabs(tspeed)>1.)
	{
		// don't start any more meteors
		return;
	}

	// if stellarium has been suspended, don't create huge number of meteors to
	// make up for lost time!
	if (deltaTime > 500)
	{
		deltaTime = 500;
	}

	// determine average meteors per frame needing to be created
	int mpf = (int)((double)ZHR*zhrToWsr*deltaTime/1000.0 + 0.5);
	if (mpf<1)
		mpf = 1;

	int mlaunch = 0;
	for (int i=0; i<mpf; ++i)
	{
		// start new meteor based on ZHR time probability
		double prob = ((double)rand())/RAND_MAX;
		if (ZHR>0 && prob<((double)ZHR*zhrToWsr*deltaTime/1000.0/(double)mpf) )
		{
			Meteor *m = new Meteor(StelApp::getInstance().getCore(), maxVelocity);
			active.push_back(m);
			mlaunch++;
		}
	}
	//  qDebug("mpf: %d\tm launched: %d\t(mps: %f)\t%d\n", mpf, mlaunch, ZHR*zhrToWsr, deltaTime);
