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!)?

if (obj->IsInstanceOf(Opoint)) ...
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

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.
