I've recently been working on a mod which requires the creation of a fairly high amount of unique blocks. The small amount of block metadata has restricted me from simply multi blocking my problems away, as I have other data riding on the metadata. I was wondering if incorporating tile entities for the sole purpose of block differentiation ( i. e. I wouldn't be using most of the other features of tile entities ) would be effective, as I feel I am going to sponge up too many block ID's. Additionally, granted I know little about their performance, I fear the performance hit of using tile entities over blocks. Any feedback would be appreciated.
