Is it possible?

I try this: (but it’s not working)

ColliderBase
```
    {
```
```
        id: collider
```
```
        bodyType: Body.Static
```
```
        Component.onCompleted:
```
```
        {
```
```
            var component = Qt.createComponent("qrc:///qml/entities/MyBox.qml");
```
```
            if (component.status === Component.Ready) {
```
```
                var col = component.createObject(collider);
```
```
                col.width = 2000;
```
```
                col.height = 20
```
```
                fixtures.push(col)
```
```
            }
```
```
        }
```
```
        onFixturesChanged: console.log("add fixture")
```
```
}
```
```
MyBoxCollider is simple Box

Hi!

The fixtures of each entity are set through the colliders and should not be modified manually.

You can dynamically add colliders to your entity, for example like this:
```
EntityBase {
    id: entity
    width: 50
    height: 50

    Rectangle {
      anchors.fill: parent
      color: "blue"
    }

    Component.onCompleted: {
      boxComp.createObject(entity)
    }
  }

  Component {
    id: boxComp
    BoxCollider {
      width: 25
      height: 25
      anchors.centerIn: parent
    }
  }
```
Best,

But what about this https://github.com/qml-box2d/qml-box2d/issues/35 ?

I have tried to create dynamically from javascript Fixture with point from json and with addFixture added to Body and it is working and drawing right but i get segfault – in presolve contact have fixture = null. So nothing can be done?

Ps: sorry for my english and thank you for reply

Hi Vadim!

It is required for us to have a closer look and do some testing / fixes to resolve possible issues with dynamically adding fixtures this way. If this feature is important for you, we can prioritize this over other features with the included support hours of Felgo Indie or Enterprise.

Let me know if this is interesting for you!

Best,
Günther
