There is not existing comand for that. Sorry...

What I am doing is to give each limb data about size, angle, offset and centre position (you can store it in arrays) and make box around limb when checking for collision of that limb. You can do it mathematicly or making box object and use inbuild collision comands.

Other way I think it would work is to make parent object with limbs but no mesh, then make each limb separate object and position object at limb position and rotation it belongs to.

Yeah, there is no command for that, there are some work-arounds though that aren't perfect but might be good enough, like if Limb15 is the "head" then use Object_ScreenY() during collision to check and see if the sphere is high enough to to be touching the head.

just a small example, I'm sure you'll think of something.

You cant! If you glue object to limb, DB stops to detect collision for it correctly. It detect collision at the place where object was before glueing. You can unglue object for collision check and then to glue it again afther of course, but that doesnt work as well, because if you unglue it, all the rotations and offset will be reset to 0...

I was already asking if thats bug, but I got no response.

I would like to know if its like this in DBpro also, so those of you, who use pro, can you please look at it may be?

...thx

so once its glued it loses it collision huh?

ok if glueing isnt the key then you could position and rotate with maths the objects to the body but what Ive found is that the objects attached this way have a slower pick up than the turning limbs at high speeds causing a lag and delay when they move at high speed turns etc.

I believe that depends on how and when you handle the movement of the limb and the parent object in the game and when you choose to sync.
