Common uses - are to expire particles prematurely, possibly giving them time to animate out. - - The Age affector only applies to particles which are still alive. -*/ -/*! - \qmlproperty int QtQuick.Particles2::Age::lifeLeft - - The amount of life to set the particle to have.

If advancePosition is false, - then the position, velocity and acceleration will remain the same and only - other attributes (such as opacity) will advance in the simulation to where - it would normally be for that point in the particle's life. With advancePosition set to - true the position, velocity and acceleration will also advance to where it would - normally be by that point in the particle's life, making it advance its position - on screen. - - Default value is true. -*/ - -QQuickAgeAffector::QQuickAgeAffector(QQuickItem *parent) : - QQuickParticleAffector(parent), m_lifeLeft(0), m_advancePosition(true) -{ -} - - -bool QQuickAgeAffector::affectParticle(QQuickParticleData *d, qreal dt) -{ - Q_UNUSED(dt); - if (d->stillAlive()){ - qreal curT = (qreal)m_system->timeInt/1000.0; - qreal ttl = (qreal)m_lifeLeft/1000.0; - if (!m_advancePosition && ttl > 0){ - qreal x = d->curX(); - qreal vx = d->curVX(); - qreal ax = d->curAX(); - qreal y = d->curY(); - qreal vy = d->curVY(); - qreal ay = d->curAY(); - d->t = curT - (d->lifeSpan - ttl); - d->setInstantaneousX(x); - d->setInstantaneousVX(vx); - d->setInstantaneousAX(ax); - d->setInstantaneousY(y); - d->setInstantaneousVY(vy); - d->setInstantaneousAY(ay); - } else { - d->t = curT - (d->lifeSpan - ttl); - } - return true; - } - return false; -} -QT_END_NAMESPACE |
