Ground Loot

The loot block now behaves like air when its container is empty, allowing interactions to pass through.

• 战利品生成方块在容器为空时，交互行为类似空气，可以穿透方块。

The "one-time" generation mode has been reworked: blocks with the NBT tag PlacedByPlayer set to 0 will use dynamic generation based on chunk loading/unloading; those with it set to 1 will use the default random tick generation.

• 重构了“一次性生成模式”的生成逻辑：当方块的 NBT 标签 PlacedByPlayer 为 0 时，使用基于区块加载与卸载的动态生成机制；为 1 时则使用默认的随机刻生成。
