While the system does not perform any simulation when stopped or paused, a restart restarts the simulation from the beginning, while unpausing resumes the simulation from where it was. + + Timed group changes is an example that highlights the ParticleGroup element. While normally referring to groups with a string name is sufficent, additional effects can be + done by setting properties on groups. + The first group has a variable duration on it, but always transitions to the second group. + \snippet examples/particles/system/content/timedgroupchanges.qml 0 + The second group has a TrailEmitter on it, and a fixed duration for emitting into the third group. By placing the TrailEmitter as a direct child of the ParticleGroup, it automatically selects that group to follow. + \snippet examples/particles/system/content/timedgroupchanges.qml 1 + The third group has an Affector as a direct child, which makes the affector automatically target this group. The affector means that as soon as particles enter this group, a burst function can be called on another emitter, using the x,y positions of this particle. + \snippet examples/particles/system/content/timedgroupchanges.qml 2 + + If TrailEmitter does not suit your needs for multiple emitters, you can also dynamically create Emitters while still using the same ParticleSystem and image particle + \snippet examples/particles/system/content/dynamicemitters.qml 0 + Note that this effect, a flurry of flying rainbow spears, would be better served with TrailEmitter. It is only done with dynamic emitters in this example to show the concept more simply. + + Multiple Painters shows how to control paint ordering of individual particles. While the paint ordering of particles within one ImagePainter is not strictly defined, ImageParticle elements follow the normal Z-ordering rules for QtQuick items. This example allow you to paint the inside of the particles above the black borders using a pair of ImageParticles each painting different parts of the same logical particle. + +*/ + +Item { + height: 480 + width: 320 + Examples.LauncherList { + id: ll + anchors.fill: parent + Component.onCompleted: { + addExample("Dynamic Comparison", "Compares with dynamically created elements", Qt.resolvedUrl("content/dynamiccomparison.qml")); + addExample("StartStop", "Start and stop the simulation", Qt.resolvedUrl("content/startstop.qml")); + addExample("Timed group changes", "Emit into managed groups", Qt.resolvedUrl("content/timedgroupchanges.qml")); + addExample("Dynamic Emitters", "Dynamically instantiated emitters with a single system", Qt.resolvedUrl("content/dynamicemitters.qml")); + addExample("Multiple Painters", "Several ParticlePainters on the same logical particles", Qt.resolvedUrl("content/multiplepainters.qml")); + } + } +} |
