nearbySmelt fuel priority

[KarolisRam]

Currently neabySmelt uses first burnable item in your inventory as fuel, maybe there should be a priority instead? For example coal > plank > log > stick > wooden_pickaxe?

I was so confused when my agent somehow kept ending up with 1 stick in inventory... this was the reason :)

The current implementation allows for agents to determine smelting priority by equipping the preferred fuel before smelting (as indeed you say the ordering is based on inventory ordering). That being said, we don't currently have this analog for the demonstrations, so BC only policies will be messed up by this. One alternative is to rectify this in the smelt action, humans who place a particular fuel in the furnace could be recorded as equipping the fuel, then re-equipping their previously held item

How to equip coal? No such action?

There is no action for equipping coal (you are limited to the ones the environment provides).
