How to combine two entities

Hello,

just bought me Blitz3D and I wanted to say "hi" to everybody.

Here is my first question concerning Blitz3D:

How can I connect two seperate entities, so that if I move one entity (e.g. a space ship), the second entity (e.g. a canon or a flight deck mounted on the ship) is moved in the corresponding position to the ship ? How can I "fix" the sub entity to the parent ?

Thanks for help in advance !

entityparent(child,parent)

thanks
