       Hi!

How do I receive the values of userdatas. I found some snippets here in the forum, but the most code snippets iterates through the user datas, but thats not what I want.

I know the exact id of the element and want to receive the value. Can anyone of you check my code?

Why? \>                          GePrint("failed"); \>                } \>

Thank you very much

bye.

The creation of your DescID is wrong. You have to make sure the type of the DescLevel is set correctly. Here an example for a Real type userdata with the ID of 1:

Matthias, you wrote:

const DescID id(DescLevel(ID_userdata, DTYPE_SUBCONTAINER, 0), DescLevel(1, DTYPE_REAL, 0));

But what if I don't know that the element is of type Real? I just tried '0' but that did not work.

Any suggestions? Thanks.

You can browse the Userdata:

Hi!

A combination of your solution and the solution of Matthias would be cool.

Not to browse through the userdatas and the condition I don't know the type of the element.
