I know this has been asked several times, and I've searched the forum for explanations, but I'm still confused. It's so easy in COFFEE but how to do it in C++?

Specifically, I want to determine if an object in the scene is a point object. According to the SDK, I should be able to do:

if(obj->GetInfo() & OBJECT_POINTOBJECT) ...

but it won't compile, in that OBJECT_POINTOBJECT is undefined. Where in the API is this (and the other OBJECT_ constants) defined? I can't find them anywhere. Or am I misinterpreting the SDK (more than likely!)?

Thanks,
Steve

Except for Splines, this works for everything (tags, materials, objects, ...). Most of the available IDs are in the SDK docs.

For Splines, use:

if (obj->GetInfo()&OBJECT;_ISSPLINE) ...

To use IsInstanceOf() with your own plugin classes, use the unique Plugin ID in place of something like 'Opoint' and add this to the top of your class definition:

class MyObject : public ObjectData
{
INSTANCEOF(MyObject,ObjectData)
...
};

Ah... thank you! I was obviously going wrong with GetInfo, IsInstanceOf does exactly what I need.

I'll be back when I hit another brick wall, many thanks in the meantime.
