Subject: [PATCH] Improve performance of mass crafts
|
|
|
|
When the server crafts all available items in CraftingMenu or InventoryMenu the game
|
|
checks either 4 or 9 times for each individual craft for a matching recipe for that container.
|
|
This check can be expensive if 64 total crafts are being performed with the recipe matching logic
|
|
being run 64 * 9 + 64 times. A breakdown of those times is below. This patch caches the last matching
|
|
recipe so that it is checked first and only if it doesn't match does the rest of the matching logic run.
|
|
|
|
Shift-click crafts are processed one at a time, so shift clicking on an item in the result of a iron block craft
|
|
where all the 9 inputs are full stacks of iron will run 64 iron block crafts. For each of those crafts, the
|
|
'remaining' blocks are calculated. This is due to recipes that have leftover items like buckets. This is done
|
|
for each craft, and done once to get the full 9 leftover items which are usually air. Then 1 item is removed
|
|
from each of the 9 inputs and each time that happens, logic is triggered to update the result itemstack. So
|
|
for each craft, that logic is run 9 times (hence the 64 * 9). The + 64 is from the 64 checks for remaining items.
|
|
|
|
After this patch, the full iteration over all recipes checking for a match should run once for a full craft to find the
|
|
initial recipe match. Then that recipe will be checked first for all future recipe match checks.
|
|
