Why QML Animation does not support setDirection like QAbstractAnimation
-
I want an object, need it to fellow a complex path and move as an animation. The path is included line and curve. just like a train.
Two solution: 1. PathAnimation or 2. states with multi-animation
Problem of solution 1: The train maybe stop at a random time-point(pause the animation), and go reverse back to the start position(play animation reversely like QAbstractAnimation ), or continue to the end point.
So i want know any way to play PathAnimation reversely?

Hi! If you need more control over the animation, you can use
PathInterpolator
:main.qml
import QtQuick 2.7 import QtQuick.Controls 2.0 ApplicationWindow { visible: true width: 400 height: 450 title: "Fun with paths" color: "darkgrey" PathInterpolator { id: motionPath path: Path { PathCubic { x: 350 y: 350 control1X: 350 control1Y: 0 control2X: 0 control2Y: 350 } } progress: slider.position } Rectangle { width: 50 height: 50 color: "orange" border.width: 3 border.color: "black" x: motionPath.x y: motionPath.y rotation: motionPath.angle antialiasing: true Text { anchors.centerIn: parent text: Math.round(motionPath.progress*100) + " %" } } Slider { id: slider anchors.bottom: parent.bottom width: parent.width } }
