[1.7.2]How much memory do tileEntityies really use?

[darty11]

I will start with this: I know next to nothing about memory usage in java, other than tile entities use more memory than blocks which aren't even actual instances of an object, but just an id for each location. I need a way of getting the locations of all my blocks, in only a certain world.  What would be the best way of doing this, making tile entities for each block, or having a list of a new object that stores a world and coordinates?

Ok, thanks.

The most important thing about TileEntities is that not that they take more memory (of course, yes they do, I'll get to that later), but that they are ticking every single game tick, which can really affect the TPS when you're having a lot of them around. You can disable that though by setting

canUpdate

in your TileEntity class to false.

 

That's a really useful tip actually.  I can see a lot of uses of non-updating (or selectively updating) tile entities.
