Bitmap setTexture vs setTextureRegion

So I realize that there are Texture and TextureRegion classes the latter of which extracts subtextures from Texture. However I'm wondering if on the native side these are viewed as objects of the same class and if its ok to do Bitmap:setTextureRegion(Texture.new(....)) and Bitmap:setTexture(TextureRegion.new(...))

@amaximov unfortunately no, they are not the same.
If you look at the docs, you will see that Texture is actually subclass of TextureBase
And TexturePack is also subclass of TextureBase, so they can be counted as same.

But TextureRegion is a superclass on its own, completely different. Thus there are two different methods (Bitmap:setTexture and Bitmap:setTextureRegion).

What you could do is try to check instance of which type is passed to method, and then call corresponding sub method.

Which I think could look like:

Bitmap._setTexture = Bitmap.setTexture   function Bitmap:setTexture(texture) if getmetatable(texture) == TextureRegion then self:setTextureRegion(texture) else self:_setTexture(texture) end end

ahh so that's how we can also do an "instance of" check. As always thanks for the help!

@amaximov that was just form the top of my head, still you'd need to try if that works
