I saw this thread and I was in favor of it almost immediately. But there is a way to do it already, but it is more costly and less effective.
Let’s say I want to craft some torches for my next mining trip. It’ll take around 3m 30s to craft about 40 torches. But that’s not enough for my adventure! Plus, I have to go study for a little while and the Blockhead will be tired by the time it’s finished crafting.
So, place a bed of some sort right next to your workbenches. Put your Blockhead to crafting the 40 torches, then make it go to the nearby bed. Do not wait for the Blockhead to craft all 40 torches, just set sleeping as the next action.
Next, tap on the workbench, then the name of the workbench. In this case, I’ll tap on the campfire and then tap “Campfire”. Then I’m able to craft 40 more torches. I can do this as many times as I like for as long as I like as long as I have enough torches and enough beds. Hope this helped
