OK, here it is. My first C++ question

I want to create a new material. Isn't this done with:

> BaseMaterial *mat = Alloc(Mmaterial);

I get a compiler error:

> error: 'Alloc' was not declared in this scope

Anyone?

Hello,

better to use
BaseMaterial *mat = BaseMaterial::Alloc(Mbase);

Cheers

There is no generic Alloc() method. Use the static Alloc() associated with the class type.

X-post.

OK, I'm now trying to use this new material, called 'mat' and assign it to a TextureTag. Like this:

> BaseContainer *container = tag- >GetDataInstance();
> container->SetData(TEXTURETAG_MATERIAL, mat);

I get a new compiler error:

> error: conversion from 'BaseMaterial*' to 'const GeData' is ambiguous

What does this mean? Should work like this, no?

((TextureTag* )tag)->SetMaterial(material);

Seems easy enough.

Hm, I think this is easy enough. But what if I really really wanted to use containers for this?

You could try:

container->SetLink(TEXTURETAG_MATERIAL, mat);

or

container->SetData(TEXTURETAG_MATERIAL, GeData(mat));

but I can't guarantee that these work.

Check the example below if you really want to use a container.
