Resupply Upgrade

The resupply upgrade takes items from the backpack and places them in the player's inventory.

Technical Details

Every time a player performs a set of actions (event based), this is triggered and the logic is run. It goes as follows:

  • Check the resupply filter for items, and if it has some

    • Check the backpack for that item, and if it is present
      • Look through player's inventory for that item, and if they have a non-full stack
        • Increase the amount to full if you can, otherwise just as much as possible
          • Decrement that amount from the stackSize of the item in the backpack
  • You also have to make sure that the item being picked up doesn't interfere with this action if it is the same item.

  • The use cases for this event triggering are a bit complex as well.

  • Optimizations are possible. For example, onBlockPlaced means you can just look at the player's active slot for the stack to refill (unless you're using something like a builder's wand).

You can probably imagine this is one of the trickier upgrades to implement.
