When MAXScript was first added to Max, the methods had to be coded explicitly to support certain object classes, but the methods were NOT exposed by these objects, so it is not possible to ask for a list of methods in these cases.
Where properties and methods are exposed via a Function Publishing Interface though, the showInterface() method will list both properties, methods and actions defined by the Interface.
For example, to see the properties and methods exposed by the inode interface, select any scene object and type in
But how do you know what interfaces an object exposes?
To see all Interfaces exposed by a node, for example, type in
(note this is plural and expects an object or class as argument, while showInterface() expects an Interface)
SplineShape was exposed explicitly in Max 2 and has not been changed since then, so it does not expose methods via interfaces. The only way to find out what methods it supports (or to be precise - what methods support SplineShape as argument) is to read the MAXScript Reference.
showMethods() along with showEvents() exists for ActiveX controls and (in Max 9) for DotNet classes, objects and controls. It does not apply to other objects.
I hope not, I have scripts written in 1997 that still work today because Autodesk does not break features for the sake of organization
I would rather see them expose what is left unexposed from those days, while leaving anything that is already there untouched, or else!:twisted:
