convertGlobalToLocalCoordinate method
Converts a global coordinate (i.e. w.r.t. the app itself) to a local coordinate (i.e. w.r.t. he game widget). If the widget occupies the whole app ("full screen" games), or is not attached to Flutter, this operation is the identity.
Implementation
Vector2 convertGlobalToLocalCoordinate(Vector2 point) {
if (!isAttached) {
return point.clone();
}
return _gameRenderBox!.globalToLocal(point.toOffset()).toVector2();
}
