n00b question, sorry if this was asked before

i would think thats your probably making to two pointers in one list.

This is a harmless debugging message in version 2.3 -- it shouldn't be appearing at all in 2.4 as far as I know...

well the thing is that it prints a crap-load of those and I'm wondering does it have an effect on the simulation's speed

It does effect simulation speed, but it shouldn't be happening in 2.4. Is there a reason 2.4 doesn't work for you?

- jon

I put in 2.4

the debug vanished. thank you

as long as we're talking about pointers. how do I set a boolean condition that says:
"if X is pointing to NULL" assuming X is type "object"?

I believe all that you need to do is something like this:

if (!X)
then{}
etc..

I think this should work, since much of the steve language works like C, and when working with pointers, this would work.

thnx a lot, that actually halped :D

now, I have a second questions.

I'm suppose to translate a breve program into a vigo program, vigo being based on C++. is there any type in C++ or in vigo that I can use instead of the steve "list"? something equivalent

I would appriciate any help.

I don't know what vigo is, but you can create a list structure in C++ with the STL vector template. Google for "STL vector" for more information.
