How do I set the rotation of an entity that has a BoxCollider? I want to make sure that the BoxCollider rotates correctly with the entity.

Also, I want to rotate the object on its center.

 

EntityBase {
    entityType: "satellite"
    entityId: satellite
    id:satellite


    Image
    {
        id:asteroidImage
        width: 300
        height: 80
        source: "images/test satellite.png"
    }

    BoxCollider
    {
        id:collider
        width: 300
        height: 80
        fixedRotation: false
        
        //HOW TO SET ROTATION OF COLLIDER AND ENTITY?

    }


    MovementAnimation {
        target: parent
        property: "pos"

        velocity: Qt.point(-200, 0)

        // start running from the beginning
        running: true
    }


}

Hi,

you can simply set the rotation property of the entity. If you want to rotate the object on it’s center, you will have to move the children of the EntityBase left and up by half their width/height, since Box2D does not support the transformOrigin property.

EntityBase {
    entityType: "satellite"
    entityId: satellite
    id:satellite
    rotation: 45

    Image {
        id:asteroidImage
        width: 300
        height: 80
        x: -width/2
        y: -height/2
        source: "images/test satellite.png"
    }

    BoxCollider {
        id:collider
        width: 300
        height: 80
        x: -width/2
        y: -height/2
        fixedRotation: false
    }

    MovementAnimation {
        target: parent
        property: "pos"

        velocity: Qt.point(-200, 0)

        // start running from the beginning
        running: true
    }
}

Cheers, Alex
