Particles with different images. [qml] - image

Question

I am using particle systems. My particles come out from the center but I want different images to come out.
The file path of these images are stored in an array. I made a function to go through that arrangement and return what is in each position.
What returns is the path of each image to be sent to the source of the ImageParticle.
The problem is that if you scroll through the entire array but only return the path of the last image and logically I get a single image instead of the twenty that are stored in the array.
Someone could help me?
Help and suggestions are well accepted.
Here is my code:
import QtQuick 2.0
import QtQuick.Particles 2.0
Rectangle {
id: bg
width: 1920 //360
height: 1080 //360
color: "black"
ParticleSystem {
id: particleSys
}
Emitter{
id: particles
anchors.centerIn: parent
height: 1; width: 1
system: particleSys
emitRate: 30
lifeSpan: 4000
lifeSpanVariation: 500
maximumEmitted: 1000
size: 5
endSize: 200
velocity: TargetDirection{
targetX: 100; targetY: 100
targetVariation: 360
magnitude: 250
}
}
property var picturesList: [
"images/Image1.png", "images/Image2.png", "images/Image3.png", "images/Image4.png", "images/Image5.png", "images/Image6.png", "images/Image7.png", "images/Image8.png", "images/Image9.png", "images/Image10.png",
"images/Image11.png", "images/Image12.png", "images/Image13.png", "images/Image14.png", "images/Image15.png", "images/Image16.png", "images/Image17.png", "images/Image18.png", "images/Image19.png", "images/Image20.png"
]
function getImage(arr){
var flag = "";
for(var i = 0; i < arr.length ; i++){
flag = arr[i];
console.log("Image: " + arr[i] + " flag: " + flag ) //To check if array is traversing.
}
return flag;
}
ImageParticle{
property var link: getImage(picturesList)
source: link
system: particleSys
}
// To check which image is returned.
MouseArea {
anchors.fill: parent
onClicked: {
console.log(getImage(picturesList))
}
}
}

I am the person who asked the previous question and here I bring the answer.
I know very well that there can be several ways that solve the problem, if you know another way I invite you to share it.
Suggestions about the response are welcome.
Here I share the code:
import QtQuick 2.0
import QtQuick.Particles 2.0
Rectangle {
id: bg
width: 1920
height: 1080
color: "black"
ParticleSystem {
id: particleSys
}
Emitter{
id: particles
anchors.centerIn: parent
height: 1; width: 1
system: particleSys
emitRate: 30
lifeSpan: 4000
lifeSpanVariation: 500
maximumEmitted: 1000
size: 5
endSize: 200
velocity: TargetDirection{ //4
targetX: 100; targetY: 100
targetVariation: 360
magnitude: 250
}
}
property var picturesList: [
"images/Image1.png", "images/Image2.png", "images/Image3.png", "images/Image4.png", "images/Image5.png", "images/Image6.png", "images/Image7.png", "images/Image8.png", "images/Image9.png", "images/Image10.png",
"images/Image11.png", "images/Image12.png", "images/Image13.png", "images/Image14.png", "images/Image15.png", "images/Image16.png", "images/Image17.png", "images/Image18.png", "images/Image19.png", "images/Image20.png"
]
ItemParticle {
id: particle
system: particleSys
delegate: itemDelegate
}
Component {
id: itemDelegate
Rectangle {
id: container
width: 26*Math.ceil(Math.random()*3); height: width
color: 'white'
Image {
anchors.fill: parent
anchors.margins: 3
source: 'images/Image'+Math.ceil(Math.random()*20)+'.png'
}
}
}
}
As you can see, all the images in the folder will be output.
I simply change the "ImageParticle" to "ItemParticle" and I add a "Component" as a delegate where the desired image will be.
So we would not use the array (omit it in the previous code) since now only the path of the image is concatenated and a random number (to select the image).
I hope you serve them, and if you have a better implementation, please let them know.
