Most shooting Addons currently available for Minecraft Bedrock Edition (MCBE) typically determine hits by detecting item usage, then spawning a projectile, and finally checking if that projectile hits an entity.
However, MCBE has a core limitation: the system cannot instantly spawn entities at the exact moment an item is used. When the system attempts to spawn an entity, it actually does so on the next game tick (a 1-tick delay). This tiny 1-tick delay leads to a less fluid shooting experience.
To address this issue, I've designed a simple method. By utilizing the world.beforeEvents.itemUse event to instantly detect item usage, and combining it with ScriptAPI's Dimension.getEntitiesFromRay() and Dimension.getBlockFromRay() for pure vector calculation, we can determine shot hits. This method completely avoids the 1-tick delay caused by spawning entities, achieving instant shooting feedback.
目前市面上大多數的 Minecraft Bedrock Edition (MCBE) 射擊類 Addon，其射擊判定機制多半是透過檢測物品使用後，生成一個投擲物，再檢測該投擲物是否命中實體來判斷。
然而，MCBE 存在一個核心限制：系統無法在使用物品的當下立即生成實體。當系統嘗試生成實體時，實際上會在下一個遊戲刻 (1 tick 延遲) 才生成，這微小的 1 tick 延遲會導致射擊體驗上的不流暢。
為了解決這個問題，我設計了一個簡單的方法。利用 world.beforeEvents.itemUse 事件來即時檢測物品的使用，並結合 ScriptAPI 提供的 Dimension.getEntitiesFromRay() 和 Dimension.getBlockFromRay() 進行純粹的向量計算來判斷射擊命中。這種方法完全避免了生成實體所造成的 1 tick 延遲，實現了即時的射擊回饋。
