RETURNED_PARAMETERS

[dushyant]

Hi

I'm trying to return some parameters from an object called in the parent object. I have placed the parameter names after the 'END' in the parameter script. In the caller, I'm doing as:

CALL 'childObject' PARAMETERS RETURNED_PARAMETERS param1

Then if I try, say

PRINT param1

it gives an error: "Unitialised variable"

I tried calling the object in the 3D script, Master script, and the Parameter script, and get the same error.

How do I access the returned parameter? I have tried in a similar way for another set of objects calling another macro, and it worked there. Don't understand what's wrong here..

Thanks

That could be also done by setting the parameter in the macro directly, not using returned_parameters.
Depends on whether you can use a fixed parameter name, or need to set different parameters conditonally.

Okay, I see. So then the parameter (of macro) would be available directly in the caller in all the scripts?

You have to add it to the parameter list of the macro and the object too. But it's enough to set in the macro, the object will see the changed value too.

Okay, thanks!
