Repeating background image

  Oh, thanks for reminding, updated first post to newer example, in case anyone will be looking at how to create repeating background.
  
  about @avo question.
  
  Are you sure that this region exists and method does not simply return nil value?
  
  Edited: sorry misread it, you said it provide table.
  
  Ok based on documentation: "The TextureRegion class specifies a texture and a rectangular region in it"
  
  How about iterating through returned table, maybe one if it's properties is the texture, other's just defining region?
  
  Well it would be just a hack, but it should work with region also, as Bitmap does.

  Hi,
  
  I have the same problem with avo, I'm trying to fill my scene's background with a textureregion from my texturepack object. Filling shape method is not working with textureregion but frankly it works with texturepack object because it inherits texturebase class.
  
  I could not find any other way to fill a shape with an image other than creating a texturepack that contains a single textureregion or using an image outside texturepack.
  My question is there any significant difference in memory consumption between using these methods?

  So, the example from the first post of this thread does not work for you?

  It works, but one of rules I learned while developing games for mobile platforms is images should be in texturepacks or textureatlas(andengine) or it will consume more memory.
  I am simply asking if the image size is a power of 2x2, will it consume more memory when it is not in a texturepack or will it consume the same memory?

  Your correct, effective use of texture atlases (or tpages - however you want to call them) is the most efficient method of drawing as it removes the need for OpenGL to swap textures and re-upload data to the video card (the slowest bit), however currently I don't think shapes accept texture regions as a valid texture type - hopefully this will be changed in a future release.
  
  Depending on the size of the image you want to repeat, you might be better off to just create a single sprite that contains several bitmaps all pointing to the same texture - I suspect (as the texture is already loaded) that the actual draw time won't be that much slower.
  
  As for the power of 2 size - that's an OpenGL restriction and in your case will actually refer to the Atlas size (if you using a single large atlas (ie 1024x1024) to hold all your resources).
