    I have problems to center my circle collider, The topleft corner of the collider is in the center of the sprite and the only way for me to center the collider is to shift x and y shouldnt i be able to use anchors.centerIn: parent?

    Its in the flappybird tutorial:


    import Felgo 3.0
    import QtQuick 2.0
    EntityBase {
        id: player
        entityType: "player"
        SpriteSequenceVPlay {
            id: bird
            anchors.centerIn: parent
            SpriteVPlay {
                frameCount: 3
                frameRate: 10
                frameWidth: 34
                frameHeight: 24
                source: "../assets/bird.png"
        CircleCollider {
            id: collider
            radius: 13
            x: -13
            y: -13
    //This dosent move the collider at all?        
    // anchors.centerIn: parent




    I found the answer in the documentation, a circle collider cant be altered with anchors. But in the flappybird tutorial where aint nothing about this. I think the tutorial need to be updated?

    Hi Isak!

    Yes you’re right, the tutorial seems to be outdated. Centering the circle collider was only possible with a previous Box2D integration, but not with the current one. Thank you for reporting this tutorial issue!
