Problem

Since 3.2.3 (#22) a node's whole cycle output had to fit the hopper above it in one go, or the cycle was held. A hopper has 5 slots, so any output with 6 or more item kinds can never fit. On Main, ThatOneBard's Exotic Fruit Orchard (guild Seire) has held 11 seeds across 6 kinds since this morning, and every activation fails with "Held output does not fit in the hopper".

Change

• The hopper gets whatever fits. The rest drops on top of it, where output used to land before 3.2.3, and the hopper pulls it in once it has room.
• When anything spills, the console logs it and the guild's online members get:
  • The hopper on your <resource> node at x, y, z is full. N items spilled on top of it and may be lost.
  • Have the hopper feed into a chest or barrel so the output has room.
• Output held by 3.2.3 (saved as pending result) is delivered the same way on the node's next activation or cycle, without a reroll. So Bard's node can be reactivated after the update.
• The held-output activation error now reads "Held output cannot be delivered yet". It can only appear when a reward item can't be created.

Testing

• mvn verify: 217 tests pass and ItemDropper and Node have full line coverage. On Windows DatabaseTest and NodePaymentsTest fail the same way on unchanged main (file-system tests), so I left them to Linux CI.
• Dev (TFMCDev01): seeded an active node with Bard's exact held output, with a barrel, a barrier and a hopper. On the first cycle the hopper got the 5 kinds that fit with exact counts, 1 lemon seed spilled on top, and the console logged Node c0ffee00… spilled 1 item past its full hopper at 3010, 121, 3010. After I freed a hopper slot, the hopper pulled the spilled seed in. Breaking the node afterwards dropped only the node item, so the held output had been cleared. The test node and blocks were removed afterwards.
• No guild member was online during the Dev test. The chat warning is covered by unit tests only.

📝 Summary

Summary by CodeRabbit

• New Features
  • When a hopper cannot hold all produced items, the remaining items spill nearby and the guild is notified with the hopper location and overflow count.
  • Delivery now completes even when some items spill, including for held output.
• Bug Fixes
  • Guild notices are sent to online members of the node’s owning guild.
  • Updated the held-output message when delivery cannot proceed.

ItemDropper now spills output that does not fit in a hopper, warns the guild, and records the result as delivered. Node adds a method to send messages to guild members with available player objects.

Guild notifications src/main/java/net/tfminecraft/dowsing/objects/Node.java, src/test/java/net/tfminecraft/dowsing/objects/NodeBehaviorTest.java	Node.notifyGuild(String) sends a message to guild members with available player objects.

It logs and reports spills to the guild, then clears the pending result and records the delivered result. Tests cover overflow, held results, and sound behaviour. The held-output activation error text also changes.

Merge Risk: 🟡 Moderate · up to 7587b

When a node's output no longer fits its hopper, the excess is now spilled on top of it. Each leftover item becomes its own dropped entity with its own pickup sound. A large held output, or a hopper left full across many cycles, can pile up many entities and slow the server near the node. Spilling overflow in full stacks before merging would avoid this.

- Around line 129-132: Update dropLoose to split the rejected amount into item
stacks no larger than item.getMaxStackSize(), dropping one entity per stack
instead of per item. Bound the pickup sounds rather than playing one for every
dropped item, while preserving the dropped quantity.
