How do I keep a part attached while animating?

动画时如何让部件保持连接？

Bind the part to a skeleton joint in the BONE (Skeleton) panel. Attached parts then move together whenever the parent joint moves.

在 BONE（骨骼）面板把部件绑定到骨骼关节上。绑定后，关节一动，部件就跟着一起动。

How to do it in 3SAX V3

在 3SAX V3 中如何操作

1. Open SG Material Group. Upload the PNG part, set its Part ID and Parent ID so the part sits in the parent-child tree, and set Anchor X/Y and Layer correctly.

1. 打开 SG 材质组。上传 PNG 部件，设置 Part ID 和 Parent ID，把部件放进父子树，并正确设置 Anchor X/Y 和 Layer。

2. Open BONE Skeleton. Bind the part to the parent joint so it follows the joint instead of moving on its own.

2. 打开 BONE 骨骼。把部件绑定到父关节，让它跟随关节而不是自己乱动。

3. Open AG Action. Add an action unit with target part = the parent join, set relative rotation / scale / X-Y offsets, and use a seq range (e.g. 01:0-5).

3. 打开 AG 动作。添加动作单元，目标部件设为父关节，设置相对旋转/缩放/X-Y 偏移，并使用 seq 帧范围（如 01:0-5）。

4. Use auto-suggest sequence to generate a seq that matches the target part's available states.

4. 用自动推荐序列生成与目标部件可用状态匹配的 seq。

5. Open CANVAS. Drag the character to fine-tune dx/dy and edit rot/scale; changes sync back into the codes.

5. 打开 CANVAS。拖动角色微调 dx/dy，编辑 rot/scale，改动会同步回代码。

6. Check the validation hints. Fix any red field before render, then render in RENDER.

6. 查看校验提示。渲染前修正红色项，再在 RENDER 渲染。

What you CAN and CANNOT do

能做与不能做

CAN: link parts into parent-child trees, bind parts to skeleton joints, drive motion from action units, count on each part having a category (join) and numbered states.
CANNOT: skip the joint bind and expect parts to follow. Parts not bound to a joint or missing a valid Parent ID will fly apart on canvas and the project validation will flag the error.
CANNOT: target a different part in the action unit than the joint you bound; the motion will not reach the part.

能：建立父子树、把部件绑定到骨骼关节、用动作单元驱动运动，每个部件都有类别（join）和编号状态。
不能：跳过关节绑定还指望部件跟随。未绑定关节或 Parent ID 无效的部件会在画布上飞散，项目校验会报错。
不能：动作单元的目标部件与绑定的关节不一致，运动不会传到该部件。
