[1.7.10] Block NBT?

[Bugzoo]

I can't find any tutorials for reading/writing block NBT. If I give the block an item, the block changes model, so I want a tutorial which shows me how to make the change to the block I right clicked on and not every one of them

override

canUpdate

to always return false, your TileEntity will then not take up CPU power, only memory (

updateEntity

will not be called every tick).

 

Oh I didn't know this!  Fancy!

 

Now, does that work for blocks that only need updates on occasion, i.e. neighbor-changed?  I'd love to be able to slim the performance on a multiblock I have (TE required, but it does nothing every tick, but does need to know when its neighbors change).

[Draco18s]

Nope, it's an either-or. Either you receive ticks, or you don't.

Everything else would be counter-productive, because then MC would have to call a method on your TE every tick anyways (to check if updateEntity should be called). That you can do yourself.

 

I don't mean "sometimes receive ticks."  I was blurring together onNeighborBlockChange for the block.  That wouldn't be affected, and that's what I was trying to get at.

For the benefit of later folks, in 1.8 this has been replaced:

 

Tickable TileEntities (eg TileEntityDaylightDetector) now implement IUpdatePlayerListBox

Non-tickable TileEntities (eg TileEntitySign) don't.
