This gives them a short period to finish fading out, - but changing lifeLeft to 0 (the default), would cause them to reach - the end of their life instantly. - - Attractor demonstrates using an Attractor affector to simulate a black hole - \snippet examples/particles/affectors/content/attractor.qml 0 - - All particles in the scene, including the rocket ship's exhaust and pellets, are pulled - towards the black hole. This effect is stronger closer to the black hole, so the - asteroids near the top of the screen are barely affected at all, while the ones - towards the middle sometimes curve drastically. To complete the effect, an Age - affector covers the black hole to destroy particles which come in contact with it. - - Custom Affector manipulates the properties of the particles directly in javascript. - One Affector is used to make the leaves rock back and forth as they fall, looking more - leaf-like than just spinning in circles: - \snippet examples/particles/affectors/content/customaffector.qml 0 - Another is used to provide a slightly varying friction to the leaves as they 'land', - to look more natural: - \snippet examples/particles/affectors/content/customaffector.qml 1 - - Friction is similar to the falling leaves in the custom affector, except that it uses a - flat friction the whole way down instead of custom affectors. - \snippet examples/particles/affectors/content/friction.qml 0 - - Gravity is a convenience affector for applying a constant acceleration to particles inside it - \snippet examples/particles/affectors/content/gravity.qml 0 - - GroupGoal sets up two particle groups for flaming and non-flaming balls, and gives you various - ways to transition between them. - \snippet examples/particles/affectors/content/groupgoal.qml unlit - The non-flaming balls have a one in a hundred chance of lighting on their own each second, but they also - have a GroupGoal set on the whole group. This affector affects all particles of the unlit group, when colliding - with particles in the lit group, and cause them to move to the lighting group. - \snippet examples/particles/affectors/content/groupgoal.qml lighting - lighting is an intermediate group so that the glow builds up and the transition is less jarring. So it automatically - moves into the lit group after 100ms. - \snippet examples/particles/affectors/content/groupgoal.qml lit - The lit group also has TrailEmitters on it for additional fire and smoke, but does not transition anywhere. - There are two more GroupGoal elements that allow particles in the unlit group to transition to the lighting group - (and then to the lit group). - \snippet examples/particles/affectors/content/groupgoal.qml groupgoal-pilot - The first is just an area bound to the location of an image of a pilot flame. When unlit balls pass through the flame, - they go straight to lit because the pilot flame is so hot. - \snippet examples/particles/affectors/content/groupgoal.qml groupgoal-ma - The second is bound to the location of the last pointer interaction, so that touching or clicking on unlit balls (which - is hard due to their constant movement) causes them to move to the lighting group. - - Move shows some simple effects you can get by altering trajectory midway. - The red particles have an affector that affects their position, jumping them forwards by 120px. - \snippet examples/particles/affectors/content/move.qml A - The green particles have an affector that affects their velocity, but with some angle variation. By adding some random direction - velocity to their existing forwards velocity, they begin to spray off in a cone. - \snippet examples/particles/affectors/content/move.qml B - The blue particles have an affector that affects their acceleration, and because it sets relative to false this resets the acceleration instead of - adding to it. Once the blue particles reach the affector, their horizontal velocity stops increasing as their vertical velocity decreases. - \snippet examples/particles/affectors/content/move.qml C - - SpriteGoal has an affector which interacts with the sprite engine of particles, if they are being drawn as sprites by ImageParticle. - \snippet examples/particles/affectors/content/spritegoal.qml 0 - The SpriteGoal follows the image of the rocket ship on screen, and when it interacts with particles drawn by ImageParticle as sprites, - it instructs them to move immediately to the "explode" state, which in this case is the animation of the asteroid breaking into many pieces. - - Turbulence has a flame with smoke, and both sets of particles being affected by a Turbulence affector. This gives a faint wind effect. - \snippet examples/particles/affectors/content/turbulence.qml 0 - To make the wind change direction, subsitute a black and white noise image in the noiseSource parameter (it currently uses a default noise source). - - Wander uses a Wander affector to add some horizontal drift to snowflakes as they fall down. - \snippet examples/particles/affectors/content/wander.qml 0 - There are different movements given by applying the Wander to different attributes of the trajectory, so the example makes it easy to play around and see the difference. -*/ - Item { height: 480 width: 320 |
