thanks for your praise, we love that! 😉
As we use the Box2D physics engine, the colliders available in V-Play are based on the Box2D colliders. Unfortunately, there’s no easy way to get rounded corners, because a radius setting similar to the Qt Rectangle is not supported for the BoxCollider currently.
You can try using a CircleCollider or PolygonCollider to get the shape you want. The CircleCollider uses a full circle, so it might not be the best if your base shape is more like a rectangle. With the PolygonCollider you can create your own custom shapes, for example an octagon shape, so the edges are cut off.
