[Closed] Callback for vertex delete

Oct 19, 2011 4:29 pm

Hi All!

I just wanted to know if there is any way to know when a vertex is added or deleted on an Editable_poly?
It could be either on Maxscript or in C++.
(for maxscript I haven’t found the correct Callback name. eg: #nodePreDelete)

I am working with 3DS MAx 2008 so no use of NodeEventCallback

Do you have any idea?

How about a when construct with the “topology” attribute?

From the maxscript help:

topology
Signaled when the topology of an object changes in the Modify panel, such as via a mesh smooth, optimize, or vertex delete.

It’s callBack day!
try this


B = Box()
convertTo B editable_poly
deleteAllChangeHandlers()
test = when topology B changes obj do 
( print (polyop.getNumVerts obj) )

cheers

Thanks guy for your help! It was something like I was looking for.

Last question : can we know which of the vertex is deleted or added?
