How to create a parent-child hierarchy between parts in 3SAX V3

如何在 3SAX V3 中创建部件父子层级

Set it in the SG Material Group panel: every part has a Part ID and a Parent ID, so linking a child's Parent ID to the parent's Part ID builds the tree.

在 SG 材质组面板中设置：每个部件都有 Part ID 和 Parent ID，把子部件的 Parent ID 填为父部件的 Part ID 即可建立层级树。

How to do it in 3SAX V3

在 3SAX V3 中的操作步骤

1. Open the SG Material Group panel and upload your PNG parts.

1. 打开 SG 材质组面板，上传 PNG 部件。

2. For each part, set Part ID, baseX/baseY, Anchor X/Y, Scale, Layer and Z-perspective.

2. 为每个部件设置 Part ID、baseX/baseY、Anchor X/Y、Scale、Layer 和 Z 透视。

3. To attach a child part, enter the parent's Part ID in the child's Parent ID field.

3. 要挂接子部件，在子部件的 Parent ID 填入父部件的 Part ID。

4. Check the green hint beside the field; red means invalid - fix using the shown example.

4. 查看输入框旁的提示：绿色有效，红色报错，按示例修正。

5. Assign a category (join) and numbered states (frames) to each part.

5. 为每个部件设置类别（join）和编号状态（帧）。

6. Optional: open BONE Skeleton and bind parts to joints so attached parts move together.

6. 可选：打开 BONE 骨骼面板，把部件绑定到关节，使挂接部件随动。

7. Open CANVAS to preview; drag to fine-tune dx/dy, edit rot/scale - changes sync back into the codes.

7. 打开 CANVAS 预览，拖动微调 dx/dy，编辑 rot/scale，改动会同步回代码。

8. Link the group in AG Action, add action units (target part, seq frame ranges, rotation, scale, X/Y offsets), then preview again.

8. 在 AG 动作组中绑定该材质组，添加动作单元（目标部件、seq 帧范围、旋转、缩放、X/Y 偏移），再次预览。

What you CAN and CANNOT do

能做与不能做

  • CAN: build multi-level parent-child trees via Part ID / Parent ID.
  • CAN: bind parts to skeleton joints for joint movement.
  • CAN: save the material group to the LIBRARY and reload it in one click.
  • CANNOT: set a hierarchy without valid Part IDs - the code is rejected and the error list points to the field.
  • CANNOT: skip input validation - wrong Parent IDs leave parts unattached, so they fly apart in preview and render fails.
  • 能做：通过 Part ID / Parent ID 建立多级父子树。
  • 能做：把部件绑定到骨骼关节实现联动。
  • 能做：将材质组保存到 LIBRARY 并一键加载。
  • 不能做：没有有效 Part ID 无法建立层级，代码会被拒绝并在错误列表定位。
  • 不能做：跳过输入校验；Parent ID 填错部件将不挂接，预览时部件飞散，渲染失败。
