Only clone if the item is actually moved -* Return true when a plugin cancels inventory move item event instead of false, as false causes pulls to cycle through all items. - However, pushes do not exhibit the same behavior, so this is not something plugins could of been relying on. -* Add option (Default on) to cooldown hoppers when they fail to move an item due to full inventory -* Skip subsequent InventoryMoveItemEvents if a plugin does not use the item after first event fire for an iteration - -diff --git a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java -index b9f5f49055..a8470e6e76 100644 ---- a/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java -+++ b/src/main/java/com/destroystokyo/paper/PaperWorldConfig.java -@@ -399,6 +399,15 @@ public class PaperWorldConfig { - squidMaxSpawnHeight = getDouble("squid-spawn-height.maximum", 0.0D); - } - -+ public boolean cooldownHopperWhenFull = true; -+ public boolean disableHopperMoveEvents = false; -+ private void hopperOptimizations() { -+ cooldownHopperWhenFull = getBoolean("hopper.cooldown-when-full", cooldownHopperWhenFull); -+ log("Cooldown Hoppers when Full: " + (cooldownHopperWhenFull ?
