[1.11] Detecting & Generating

[abused_master]

Hey guys, i got a few questions regarding a generator im making that uses anything that is burnable

#1 how can i check say coal or charcoal was in the slot?

#2 how can i make it consume that item and turn it into energy? like a coal generator lets say, and generate the amount energy i want with the value i specify

how can i check say coal or charcoal was in the slot?

Coal and charcoal use the same item, just different metdata. So just check for

Items.COAL

without checking metadata and you will cover both.

 

how can i make it consume that item and turn it into energy? like a coal generator lets say, and generate the amount energy i want with the value i specify

To consume an item you can use the

extractItem

method on your

IItemHandler

.

How to generate energy from that depends on how you have energy implemented in your system. In the simplest case you only have to increment an

int

field in your TileEntity class.

Im not sure what method to use to check if the item is in that slot

To get an item from a slot you use

IItemHandler::getStackInSlot

(duh). To get an

Item

from an

ItemStack

you use

ItemStack::getItem

(also duh).

Quick question I have seen you do this but what do the "::" mean is it the same as using "#"?

That is pretty much what it means. The

::

is actually an operator added in Java 8 to reference methods so they can be used for various things e.g. passing a

Function

as a parameter of a method. Probably not the best explanation, but this is what I know of them.

Ahh and then that prompted me to look up lambda expressions which are pretty cool. (Been meaning to do that for a while now though). Thanks.

Yeah, I use :: to mean "this is an instance method", because Foo.method looks like you invoke it on the class. Could use # as well, but :: looks cooler
