How do I make a part bounce using actions?

如何在 3SAX V3 用动作组让部件弹跳？

In 3SAX V3, a bounce is an Action Group (AG) action unit bound to a material part, with a sequence of frame states that change rotation, scale, or offsets over time.

在 3SAX V3 中，弹跳是一个绑定到材质部件的动作组（AG）动作单元，通过一段帧状态的序列改变旋转、缩放或偏移来完成。

How to do it in 3SAX V3

在 3SAX V3 怎么做

1. Open the SG Material Group tab and upload the PNG part. Set Part ID, baseX/baseY, Anchor X/Y and Scale. Add numbered states (frames) for the part.

1. 打开 SG 材质组标签页，上传 PNG 部件。设置 Part ID、baseX/baseY、Anchor X/Y 和 Scale。为部件添加编号状态（帧）。

2. Switch to the AG Action tab and bind the material group.

2. 切换到 AG 动作标签页，绑定材质组。

3. Add an action unit. Set target part to the part's join.

3. 添加一个动作单元，把目标部件设为该部件的 join。

4. Set a seq frame range (e.g. 01:0-5) covering the states you defined.

4. 设置 seq 帧范围（如 01:0-5），覆盖你定义的状态。

5. Set relative rotation, scale and X/Y offsets per frame to create the up-down bounce.

5. 逐帧设置相对旋转、缩放和 X/Y 偏移，形成上下弹跳。

6. Use auto-suggest sequence to generate a seq matching the part's available states if unsure.

6. 不确定时用"自动建议序列"生成与部件可用状态匹配的 seq。

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

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

8. Save the action to LIBRARY if you want to reuse it later.

8. 想以后复用，就把动作保存到 LIBRARY。

What you CAN and CANNOT do

能做什么、不能做什么

Can:

能：

Bind parts by join, animate rotation/scale/offsets per frame range.
Trigger events from actions.
Preview and tweak on CANVAS.
Save and reload actions from the server library.

按 join 绑定部件，按帧范围做旋转/缩放/偏移动画。
从动作触发事件。
在 CANVAS 上预览和微调。
从服务器库保存和加载动作。

Cannot:

不能：

Bounce a part without defined numbered states; the seq hint will show a red error with a fix example.
Make the tool compose music, generate saxophone sounds or build instruments; it does not.
Skip frame ranges; a mismatched seq is rejected by validation.

没有定义编号状态就无法弹跳；序列提示会显示红色错误和修改示例。
让工具自己作曲、生成萨克斯音色或制作乐器；它做不到。
跳过帧范围；不匹配的序列会被校验拒绝。
