Why can't only the customed property "kind" one be allocated data correctly?

[melliol]

Below are the part of my main codes where I try to allocate the data"root.bulletkind" which has been defined correctly to a incubator to creat a object.

What the problem is that except"kind",all of the other property could be allocated correctly,and toward is a customed property,and below is the part of my bullet.qml codes:

It always console log "undefined" for "root.kind",I don't know the reason.I think the customed proeprety "toward" is same to it,but it just can't work correctly😵‍💫

Ids don't work like properties. You can try something like this.

function fire(t,nx,ny){
        var comp = Qt.createComponent("MyBullet.qml");
        var incubateMe = comp.incubateObject(root,{x:nx,y:ny,toward:t})
        incubateMe.onStatusChanged = function(status){
            if (status === Component.Ready){
                console.log("Bullet object is ready ")
                incubateMe.object.kind = root.bulletKind
                incubateMe.object.visible = true
                incubateMe.object.color = "red";
            }
        }
    }

You can refer the complete example here

Also don't post the images. pasting the code or example will help.

Below are the code of the main QML I have corrected

function fire(t,nx,ny)
{
    var com=Qt.createComponent("bullet.qml");
    var incubator=com.incubateObject(root,{x:nx,y:ny,toward:t});
    incubator.onStatusChanged=function(status)
    {
        if(status===Component.Ready)
        {
            console.log("OK");
            incubator.object.visible=true;
            incubator.object.kind=root.bulletkind
            incubator.object.destroy(4000);

            addbullet(incubator.object);
        }
    }
}

And below are my bullet.qml:

import QtQuick

Rectangle
{
    id:root;
    width:20;
    height:width;
    radius:width/2;
    visible:false;
    z:1;
    color:"yellow";
    property var toward;//1对应左，2对应上，3对映右，4对应下
    property int speed:200;
    property var kind;
    // property var bound:[];//1对应左，2对应上，3对映右，4对应下

    onVisibleChanged:
    {
        if(visible)
        {
            console.log(root.kind);
            moveanimation(root.toward,root.kind);
        }
    }
    // onXChanged:
    // {
    //     if(x<=bound[1]||x>=bound[3])
    //     {visible=false;
    //     console.log("消失在x")}
    // }
    // onYChanged:
    // {
    //     if(y<=bound[2]||y>=bound[4])
    //      {   visible=false;
    //     console.log("xiao shi zai y")}
    // }
    NumberAnimation
    {
        id:ani;
        target:root;
        easing.type:Easing.Linear;
        onFinished:
        {
            root.visible=false;
        }
    }

    function moveanimation(a,b)//a用来选择方向，b用来选择动画
    {
        //here I want to use kind to choose the style that the bullet shoot
        // switch(b)
        // {
        // case 1:
        // {
        //     ani.easing.type=Easing.InOutExpo;
        //     root.speed=200;
        //     break;
        // }
        // case 2:
        // {
        //     ani.easing.type=Easing.Linear;
        //     root.speed=300;
        //     break;
        // }
        // case 3:
        // {
        //     ani.easing.type=Easing.InOutElastic;
        //     root.speed=200;
        //     break;
        // }
        // }
        switch(a)
        {
        case 1:
        {
            ani.property="x";
            ani.duration=1000*x/(root.speed);
            ani.to=0;
            ani.start();
            break;
        }
        case 2:
        {
            ani.property="y";
            ani.to=0;
            ani.duration=1000*y/(root.speed);
            ani.start();
            break;
        }
        case 3:
        {

            ani.property="x";
            ani.to=640;
            ani.duration=1000*(640-x)/(root.speed);
            ani.start();
            break;
        }
        case 4:
        {

            ani.property="y";
            ani.to=480;
            ani.duration=1000*(480-y)/(root.speed);
            ani.start();
            break;
        }
        }
    }
}

@dheerendra Sorry,I have tried like you telling,but it still can't work in my project😵‍💫I am ready confused why could this happen?

[dheerendra]

Code is not exactly same as mine. Revert the order like the following. It works.

incubator.object.kind=root.bulletkind
incubator.object.visible=true;

@dheerendra Amazing🥳！It works,but why could not it run correctly before?I think thery are similar,just a little different.Is the problem on the order of the property?🧐
