This would appear at first glance to be a proper meta message. I thought so at first as well. It isn't. The first part is fine - TTexture meta new sends a meta message of #new to the class TTexture. This returns a texture. We then send a message: #initializeWithForm: bbForm mipmap: true shrinkFit: true extension: #colorKeyZero. to this new texture. Notice that THIS message is not replicated. Oops. The (current) proper way to do this is: tex := TTexture meta new. tex meta initializeWithForm: bbForm mipmap: true shrinkFit: true extension: #colorKeyZero. or this: tex := TTexture meta new meta initializeWithForm: bbForm mipmap: true shrinkFit: true extension: #colorKeyZero. This seems unfortunate to me. The intent of tex := TTexture meta new initializeWithForm: bbForm mipmap: true shrinkFit: true extension: #colorKeyZero. seems quite clear to me. Unfortunately, you can't just have TTexture meta new return a TMeta object, as we don't know if we will have a followon message or not. If we don't then tex := TTexture meta new. sets tex to a meta object which will always replicate ANY message sent to it. While that is perhaps useful in some cases, it is probably not usually a good idea. For new, keep an eye on this pattern. We should really think about how we might like to change this. This particular problem was in at least two places in this fix.
