I would like to know what is the best way to generate a kind of "ore" that stores some data which I can get somehow later (breaking or right click). I plan to get more than 16 "types of ore", so I cannot use metadata. I also think that I cannot use tile entities since it would be spawned and probably cause a terrible lag.

 

So, what do you guys suggest?

 

(I had a strange idea about textures. If they have textures with different paths, then I would be able to compare later.)

 

Thanks for all the help.

Thanks for your reply, diesieben07. I have figured out another approach for my problem without using TE. I created a class that returns values depending on the block position, which is basically what I needed.
