npx skills add https://github.com/dylantarre/animation-principles --skill 'Animation Principles - Teaching Others'教授动画法则需要因材施教。以下是如何针对不同水平的学生传达每一条法则。
首先展示: 弹跳球练习——普适、直观、无可辩驳。常见误区: 学生保持形状而非体积。使用黏土演示。关键短语: "体积保持不变,形状改变。"
首先展示: 真实运动员的视频——每次起跳前都有下蹲。常见误区: 预备动作做得过大或过长。关键短语: "观众需要提前知道。"
首先展示: 剪影测试。如果无法通过阴影识别动作,则说明失败。常见误区: 在建立清晰度之前堆砌细节。关键短语: "这一帧要表达的唯一一件事是什么?"
首先展示: 用两种方式制作相同的动作——比较结果。常见误区: 认为其中一种方法是"正确的"。关键短语: "关键帧动画用于控制,逐帧动画用于探索。"
首先展示: 慢动作下的头发、布料、尾巴。自然界一直在展示。常见误区: 所有东西在同一帧停止。关键短语: "没有东西会同时停止。相连的部分会继续运动。"
首先展示: 推一个重箱子和一个轻箱子。间距会变化。常见误区: 均匀的间距(补间综合征)。关键短语: "在慢的地方用更多张画,在快的地方用更少张画。"
首先展示: 追踪自然手势中手的运动轨迹——它是弯曲的。 机械的点对点运动。 "几乎所有东西都沿弧线运动。直线运动是例外。"

首先展示: 边走边打电话——多重层次。常见误区: 次要动作与主要动作冲突。关键短语: "它增加风味,但不应该抢戏。"
首先展示: 在 4、8、12、24 帧下制作相同的动作——感受差异。常见误区: 对所有事物都默认使用相同的节奏。关键短语: "节奏就是表演。相同的姿势,不同的节奏 = 不同的含义。"
首先展示: 比较照片参考和迪士尼的诠释。常见误区: 害怕做得太过(比做得不够更常见)。关键短语: "找到现实,然后在此基础上推进 20%。"
首先展示: 将一个简单的角色旋转 360 度。体积必须保持。常见误区: 描绘符号而非形体。关键短语: "你能想象绕着它走一圈吗?"
首先展示: 角色阵容——你想看哪些角色?常见误区: 认为吸引力意味着"漂亮"。关键短语: "吸引力是磁性的。即使是反派也需要它。"
从节奏 + 挤压与拉伸(弹跳球)开始。然后加入弧线运动 + 慢入慢出。逐步增加复杂度。演出布局和吸引力放在后面——它们需要视觉词汇。

Teaching animation principles requires meeting students where they are. Here's how to communicate each principle at different levels.
Show first: Bouncing ball exercise - universal, immediate, undeniable. Common confusion: Students preserve shape instead of volume. Use clay demonstration. Key phrase: "Volume stays the same, shape changes."
Show first: Video of real athletes - every jump has a crouch. Common confusion: Making anticipation too large or too long. Key phrase: "The audience needs a heads-up."
Show first: Silhouette test. If they can't read it as a shadow, it fails. Common confusion: Cluttering with detail before establishing clarity. Key phrase: "What's the ONE thing this frame says?"
Show first: Same action animated both ways - compare results. Common confusion: Thinking one method is "correct." Key phrase: "Pose to pose for control, straight ahead for discovery."
Show first: Slow-motion hair, fabric, tails. Nature demonstrates constantly. Common confusion: Everything stopping at the same frame. Key phrase: "Nothing stops at once. What's attached keeps going."
Show first: Push a heavy box versus a light one. Spacing changes. Common confusion: Even spacing (tweening syndrome). Key phrase: "More drawings where it slows, fewer where it's fast."
Show first: Trace hand during natural gesture - it curves. Common confusion: Mechanical point-to-point movement. Key phrase: "Almost everything curves. Straight lines are exceptions."
Show first: Walking while talking on phone - multiple layers. Common confusion: Secondary action competing with primary. Key phrase: "It adds flavor but shouldn't steal the show."
Show first: Same action at 4, 8, 12, 24 frames - feel the difference. Common confusion: Defaulting to same timing for everything. Key phrase: "Timing is the acting. Same pose, different timing = different meaning."
Show first: Compare photo reference to Disney interpretation. Common confusion: Fear of pushing too far (more common than pushing too much). Key phrase: "Find reality, then push 20% past it."
Show first: Turn a simple character 360 degrees. Volume must hold. Common confusion: Drawing symbols instead of forms. Key phrase: "Can you imagine walking around it?"
Show first: Character lineup - which ones do you want to watch? Common confusion: Thinking appeal means "pretty." Key phrase: "Appeal is magnetic. Even villains need it."
Start with Timing + Squash/Stretch (bouncing ball). Add Arcs + Slow In/Out. Build complexity gradually. Staging and Appeal come later - they require visual vocabulary.
