 ## 背景

-当前大鱼运行时使用左下固定虚拟摇杆，玩家必须点到摇杆区域才能移动。移动端实际体验应改为屏幕任意位置触控：第一次触点只建立方向原点，不直接产生移动；后续触点相对原点形成方向向量，角色按恒定速度朝该方向行动。
+当前大鱼运行时使用左下固定虚拟摇杆，玩家必须点到摇杆区域才能移动。移动端实际体验应改为屏幕任意位置触控：按住屏幕时不再用“触点相对按下原点”的距离判断方向，而是按固定采样间隔比较“上一次触点位置”和“当前触点位置”的位移方向，角色按恒定速度朝采样方向行动。

 ## 交互规则

-1. 玩家在玩法舞台内按下时，记录第一个触点坐标为本次操作原点。
+1. 玩家在玩法舞台内按下时，记录当前触点坐标为采样起点。
 2. 按下瞬间提交 `{ x: 0, y: 0 }`，保证一开始玩家不动。
-3. 手指/鼠标移动后，用“当前触点 - 原点”的向量计算方向。
-4. 输入只表达方向，不表达速度；超过死区后归一化为单位方向向量。
-5. 松开或取消触控后，清空操作原点并提交 `{ x: 0, y: 0 }`。
-6. 前端继续定时提交当前方向，即使没有玩家输入也提交零向量，让后端或本地直达局持续推进世界 tick。
+3. 按住期间每 `0.1` 秒采样一次当前触点坐标，并用“当前触点 - 上一次采样触点”的位移计算方向。
+4. 输入只表达方向，不表达速度；超过采样死区后归一化为单位方向向量，未超过死区则沿用上一段有效方向。
+5. 每次采样完成后，把当前触点写为下一次采样的“上一次位置”。
+6. 松开或取消触控后，清空采样状态并提交 `{ x: 0, y: 0 }`。
+7. 前端继续定时提交当前方向，即使没有玩家输入也提交零向量，让后端或本地直达局持续推进世界 tick。

 ## 本地直达局边界

- `/big-fish` 的本地占位局必须在玩家未操作时继续移动野生对象。
+- 大鱼吃小鱼的最终游玩部分统一放在前端本地 runtime，不再调用后端 start/input/get run 接口。
+- 后端只保留 Agent 创作、草稿编译、资产生成、发布和作品列表；不负责移动、碰撞、刷鱼、合成、屏外清理或胜负模拟。
+- `/big-fish` 的本地直达局和平台内测试玩法必须共用前端本地 runtime，并在玩家未操作时继续移动野生对象。
 - 玩家速度保持恒定，只由方向决定移动方向。
 - 野生对象使用确定性游动规则，避免直达入口看起来像静态截图。

 ## 验收口径

 1. 在舞台任意位置按下时玩家不立即移动。
-2. 按住并拖动后，玩家朝拖动方向恒速移动。
+2. 按住并拖动后，玩家方向来自最近 `0.1` 秒位移，而不是来自按下原点。
 3. 松开后玩家停止。
 4. 不操作时野生对象仍会持续游动。
+
+## 资产生成补充口径
+
+- 大鱼实体主图、`idle_float` 和 `move_swim` 动作图都按 RPG 角色资产口径处理：单体完整入镜、中心构图、轮廓清晰、透明背景、无 UI/文字/水印。
+- 场地背景只生成环境，不生成规则说明、UI 或巨大主体遮挡；画面元素要少，中央活动区域要大，边缘只保留少量出生区提示。
