As many users already has discovered there are some serious issues with rotating objects. For example one bug makes objects dissapear when attached to others with the Glue Limb command. This makes terrain following code from the original DB Tank Demo impossible to use in DBPro.
However, instead of using a rotate object command to rotate the object and the piece that is glued to it one can use the rotate limb command instead. In the old Tank code a dummy cone is set up and glued to the tank. Using the code as it is in DBPro will make the tank dissapear when rotated in certain angles. But by using the Rotate Limb with the cone object number and a limb number of zero this technique of obtaining control over object rotation will work also in DBPro.
