At least, there is nothing silly in your suggestion, Alberto, it sounds quite interesting to me. It could spare a bunch lines in coding for a very basic and often used function.

Can you tell some examples what for you used it?

I think it makes easier to understand a suggestion, if one knows the purposes.
Thank you!

Parent-child heirachies are used in quite a few engines, and in other software. Anything done to the parent will affect the child. For example, if I move an entity, all its children will move, too.

You are absolutely right, too. You posted here in the Future forum, so you weren't looking for alternative solutions to your problems, you wanted Contitec to implement these Blitz3D features for you. Good luck, and I won't reply anymore.

For example to create a camera following the player
You create pivot and you attach it to the player then you make the camera child to the pivot

Does it affect the camera's turn/rotate (pan etc.), too?
And can it affect the turn/rotate only?
And, if you attached it can it be 'de-attached' it easely, or is it attached for the whole time when it is called once?

Rotating of child entities about its parent can be very easily implemented by a small script - so, unlike with BlitzD, it does not make much sense here to build this into the engine. It would not be any faster or have any other advantages over a script.

You can however post this suggestion onto the template forum for Doug to provide a general purpose script for this. Give some examples how you would use this feature.

Does it affect the camera's turn/rotate (pan etc.), too?

The camera pan, no
Actually you create an orbit camera
you turn the pivot and the camera moves around the player
yes ,it can be de-attached

I do think that having some kind of parent-child system that is easy to use would be a good thing. While you can do this with pointers and handles, sometimes i have wanted an easy way to simply "destroy all children entities". So instead i have to make some junky function that loops through all objects or has some linked list or whatever..It would be nice if you could set the parent object at creation, and then that parent object can have a special function like:

remove_child_ents()
hide_child_ents()

or whatever....

and of course the child objects would get a special pointer "parent" ..
