I've not used containers before, sorry if I seem a little helpless! Is it possible, using the example I've given, to convert the enemy animations and containers to a container so this works? So far, my main character is just pinned to it's container, and that was how I was doing this.
EDIT: Creating a container
To add an object to a container, select one of the objects you want in the container and click the Create link in its properties (which appears under the Container category next to the label No container). A dialog opens allowing you to choose the object to add to the container.
Seems to work!
