问题
From apples documentation: "You can only request mipmaps if both of the texture’s dimensions are a power of two."
However, it's unclear whether the SKTextures from SKTextureAtlas's also support this feature (since they're essentially a bit different in nature).
I ask the question because it's actually hard to see if anything is getting mipmapped from the results.
回答1:
First off a SKTexture from a SKTextureAtlas does not support mipmapping. Secondly sometimes mipmapping doesn't even work with a regular SKTexture it depends a lot on how it is nested inside the node structure.
