Passing entitys directly

Can some kind person please shed some light on this lil problem for me.

I'm trying to pass a handle of an object into a function, seems to work as long as the object isnt a CHILD of an object.

Here's what I'm doing:

loading 'body' as parent object
loading 'head' as child of body object

passing the handle of the object into a function

disp(body)
disp(head)

..

function disp(temp_handle#)
..
positionentity temp_handle#,1,1,1
..
end function


Works fine for body, but I get an error of 'entity does not exist' for the head. I think as its a child object, its not sending the correct pointer to the routine ?.

Are both handles made global?

yes.. they are now. [ whoops ]

didnt make any difference though..

Like I said, if I take out the call to the function for 'head' - the body works fine. Is it something to do with the way blitz stores child objects ? - are they somehow attached to the main handle as an offset ?? (so it's not passing the correct pointer)

Don't use floats for handles.

got around the problem by making the second object a normal object. (parent)

So I guess the error is something to do with it being a child - anyway thanks for the suggestions.

try putting a global flag on the positionentity

And, like Fredborg said, don't use a float. No reason to use a float when all entity handles are integers.

Especially because they are bound to cause Memory Access Violations, as they don't have the same numeric span and/or precision as integers.
