Unsolved ParticleSystem doesn't always show until device interacted with
-
Hi,
I use QML ParticleSystem to show a little snow effect in my App for winter, but for some reason it's very intermittent when it shows, some App launches it is visible straight away and others I have to interact with the App in some ways (Open a menu or push a page onto the stack for example) which causes it to abruptly show.
I'm using Qt 5.6 on Sailfish OS (yeah we are still stuck on 5.6 yey)
This is the code:
ParticleSystem { id: particleSys Component.onCompleted: {checkIfAllowed();} function startSnow(){emitter.burst(emitter.emitRate)} function checkIfAllowed(){var month=Qt.formatDateTime (new Date(), "MM"); if(appsettings.getSystemSetting("snowEffect", "")==="true"){ if(month==="11"){startSnow();} else if(month==="12"){startSnow();} else if(month==="01"){startSnow();} else if(month==="02"){startSnow();} else{emitter.destroy();imgpart.destroy();particleSys.destroy();} } } } Emitter{ id: emitter focus:true startTime: 10 anchors{top:parent.top;} height:parent.height/1.5; width: parent.width system: particleSys emitRate: 15 layer.enabled: true lifeSpan: 3000 lifeSpanVariation: 300 maximumEmitted: 800 size: 4 endSize: 30 velocity: TargetDirection{ targetX: 0; targetY: 0 targetVariation: 360 magnitude: 150 targetItem: pillButton } } ImageParticle{ id: imgpart color:lightTheme? "black": "white" source:"images/snowflake.png" system: particleSys }
I've shot a tiny video to show what it's doing:
If anyone has any ideas please do share them :)
