We have multiple ways to more or less do the same thing:
What he does: Having 1x1 loaders, that are loading invisible chests. And then he is moving items from intput-chests to output-chests and then the 1x1 loaders are emptying the chests again.
My method is: Moving items from the belt into a list of SimpleItemstack
s. And moving them back onto belts, if possible.
I would say, both methods are valid and i dont think any method is faster than the other. I have the overload of dealing with belts. And he has the overload with dealing with how chests work. Also it would be closely impossible to have such buffer chests, without unexpected behaviour (especially with future plans). Also i dont have the space to use the 1x1 loaders, my whole entity is only 1x1 big.
You still can change my mind here, but im pretty sure, that will be equally fast :)
