From worst to best:

  • Using an array of separate images and assigning the textures to the material for each frame.

  • Having a page containing all the images for a single "sprite" and animating using the texture offset for the material.

  • Using a texture atlas (texture for multiple objects) and animating the uv coordinates in the mesh (not using the texture offset of the material) for each.

  • Displaying all the 'objects' in a single mesh, each getting its own four vertices and two triangles. Use a texture atlas for the contents, and modify the UV coordinates for each 'object'.
