QML --》动画分组

1、平行动画

关键字(ParallelAnimation):当开始时，平行元素的所有子动画都会平行运行，它允许你在同一时间使用不同的属性来播放动画。

import QtQuick 2.0

Rectangle{
    id:root
    width: 1000;
    height: 1000;
    property int duration:3000;
    Clickable{
        id:rocket;
        x:20;y:520;
        source: "./1.png";
        onClicked: anim.restart();
    }
    ParallelAnimation{
        id:anim;
        NumberAnimation{
            target: rocket;
            properties: "y";
            to:20;
            duration: root.duration;
        }
        NumberAnimation{
            target: rocket;
            properties: "x";
            to:500;
            duration: root.duration;
        }
    }
}

从(20,520)移动到(500, 20)；

 

2、连续动画

关键字：(SequentailAnimation)

Rectangle{
    id:root
    width: 1000;
    height: 1000;
    property int duration:3000;
    Clickable{
        id:rocket;
        x:20;y:520;
        source: "./1.png";
        onClicked: anim.restart();
    }
    SequentialAnimation{
        id:anim;
        NumberAnimation{
            target: rocket;
            properties: "y";
            to:20;
            duration: root.duration*0.6;
        }
        NumberAnimation{
            target: rocket;
            properties: "x";
            to:500;
            duration: root.duration*0.4;
        }
    }
}

运行方式：(20, 520) ---->(20, 20) ---->(500, 20)
