🌙 飞蛾效应 (The Moth Effect)
At night, bats are attracted to artificial light sources (torches, lanterns, campfires, sea lanterns). When within 10 blocks of a valid light block with Block Light > 8, BatHuntLightGoal activates. Bats approach the light and transition into smooth circular orbits.
📐 切向旋回向量数学
The orbital velocity vector is calculated perpendicularly to the radial position vector $\vec{r} = \vec{P}{\text{bat}} - \vec{P}{\text{light}}$:
$$\vec{V}{\text{tangent}} = \frac{(-r_z, 0, r_x)}{|\vec{r}|} \times v{\text{orbit}}$$
A sine-wave vertical modulation adds organic natural bobbing:
$$V_y = A \sin(\omega t)$$
