How do I animate rotation of a part in 3SAX?

3SAX V3 中如何为一部件制作旋转动画

Last updated: 2026-10-21

Animate part rotation in the Action Group (AG) panel by binding a material group, adding an action unit targeting the part's join, and setting relative rotation over a seq frame range. The CANVAS preview and BONE binding keep attached parts moving together.

在 3SAX 中，为部件做旋转动画需在 Action Group（AG）面板绑定材质组、添加指向该部件 join 的动作单元，并在 seq 帧范围内设置相对旋转。CANVAS 预览与 BONE 绑定可让相连部件一起运动。

How to do it in 3SAX V3

在 3SAX V3 中的操作步骤

1. Open the SG Material Group panel; upload the PNG part and set Part ID, Parent ID, baseX/baseY, Anchor X/Y, Scale, Layer, and Z-perspective.

1. 打开 SG Material Group 面板；上传 PNG 部件，设置 Part ID、Parent ID、baseX/baseY、Anchor X/Y、Scale、Layer、Z-perspective。

2. Open AG Action; bind the material group.

2. 打开 AG Action，绑定材质组。

3. Add an action unit: set target part = the part's join, set seq frame range (e.g. 01:0-5), and enter relative rotation.

3. 添加动作单元：目标部件设为该部件的 join，设置 seq 帧范围（如 01:0-5），输入相对旋转。

4. Optionally set scale / X-Y offsets in the same unit.

4. 可在同一单元设置缩放 / X-Y 偏移。

5. Click auto-suggest sequence to generate a seq matching the part's available states.

5. 点击 auto-suggest sequence，按部件可用状态自动生成 seq。

6. Open CANVAS to preview; drag to fine-tune dx/dy, edit rot/scale (syncs back to codes).

6. 打开 CANVAS 预览；拖动微调 dx/dy，编辑 rot/scale（同步回代码）。

7. For linked parts, open BONE and bind parts to the joint.

7. 需要联动的部件，打开 BONE 绑定到骨骼关节。

8. Save the action to LIBRARY for one-click reuse, or go to RENDER for MP4 (720x1280 or 1280x720).

8. 将动作保存到 LIBRARY 一键复用，或到 RENDER 渲染 MP4（720x1280 或 1280x720）。

What you CAN and CANNOT do

能做与不能做

CAN: rotate a part via AG relative rotation over seq frames.
CAN: preview and tweak in CANVAS with code sync.
CANNOT: rotate a part never uploaded or with no bound join — the code will not resolve it.
Doing the wrong thing: an invalid frame range or missing required field flags red hints and blocks render; wrong Parent ID / joint makes attached parts fly apart.

能做：在 AG 中用相对旋转按 seq 帧旋转部件。
能做：在 CANVAS 预览并调整，改动同步回代码。
不能做：旋转未上传或无绑定 join 的部件——代码无法解析。
做错时：帧范围无效或必填项缺失会显示红色提示并阻止渲染；Parent ID / 关节错误会导致部件飞散。
