I’m following the tutorial FlappyBird. When creating the Player.qml:

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
    }
}

I tried to run the game. But the bounding box result was not same as the tutorial: Tutorial_Image vs My result

The bounding box didn’t wrap up the image. What is my wrong? Thank you very much!

Hi Vi,

please add the following code to the CircleCollider:

x: -radius
y: -radius

There have been minor changes to the physics engine. The point of origin of the CircleCollider is now the upper left corner and not the center, thus we have to move it a little to position it in the center in this case.

We will update the tutorial accordingly, thank you very much for noticing this issue!

Cheers,
Alex

Correct! Thank you so much Alex!
