I got a block VAT that checks nearby FURNACE and do stuff IF smelting the right items.

 

IF nearby FURNACE smelting Iron ore do X  PER Iron ore smelted.

IF  nearby FURNACE smelting Gold ore do Y PER Gold ore smelted.

 

 

The way I figured it out is to enable random tick and to schedule updates at block placement every 60 ticks which is like 2 sec. So every 2 seconds I'm polling the inventory of nearby Furnaces see if they are doing anything. Note that my system actually works is just runs all the time when the chunk is load even if Furnace is off  doesn't matter it will keep on polling. Works but seems a bit wasteful.

 

Is there any other way say some event fired whenever the furnace finishes smelting something? Or can I tap into it somehow create my own custom event listener for that specific furnace to check if anything is finished smelting?

 

Any thoughts or suggestions?

enable random tick

and

to schedule updates at block placement every 60 ticks

 

Random ticks are not scheduled ticks.  Literally.

I mean...you could go look at TileEntityFurnace....

But no, there is not

Apparently to enable updateTick which is actually what I use you need to have setRandomTick(true)  . YEAHHHH LOGIC!!!

 

Not but seriously. When you set random ticking you enable ticking in general. Otherwise is disabled. So updateTick() function starts working.

 

So atBlockPlaced I schedule an update tick and after that I just use updateTick and ignore randomTick function

...no, that's not how that works.  You need to schedule the first tick yourself onBlockPlaced.

Yeah that's what I did!  I schedule the first one 60 ticks then at the end up tickUpdate i schedule it again
