This example makes it easy to see what happens when the limit is reached. + + Shape and Direction emits particles out of an unfilled Ellipse shape, using a TargetDirection + \snippet examples/particles/emitters/content/shapeanddirection.qml 0 + This sends the particles towards the center of the ellipse with proportional speed, keeping the ellipse outline as they move to the center. + + TrailEmitter uses that element to add smoke particles to trail the fire particles in the scene. + \snippet examples/particles/emitters/content/trailemitter.qml 0 + +*/ + +Item { + height: 480 + width: 320 + Examples.LauncherList { + id: ll + anchors.fill: parent + Component.onCompleted: { + addExample("Velocity from Motion", "Particle motion just by moving emitters", Qt.resolvedUrl("content/velocityfrommotion.qml")); + addExample("Burst and Pulse", "Emit imperatively", Qt.resolvedUrl("content/burstandpulse.qml")); + addExample("Custom Emitter", "Custom starting state", Qt.resolvedUrl("content/customemitter.qml")); + addExample("Emit Mask", "Emit arbitrary shapes", Qt.resolvedUrl("content/emitmask.qml")); + addExample("Maximum Emitted", "Put a limit on emissions", Qt.resolvedUrl("content/maximumemitted.qml")); + addExample("Shape and Direction", "Creates a portal effect", Qt.resolvedUrl("content/shapeanddirection.qml")); + addExample("TrailEmitter", "Emit from other particles", Qt.resolvedUrl("content/trailemitter.qml")); + } + } +} |
