What start frame and end frame mean in an action

动作中的起始帧和结束帧是什么意思

In an Action Group (AG), the start frame and end frame define the seq range an action unit plays — which states of the target part are used and when that action begins and ends inside the clip.

在动作组(AG)中,起始帧和结束帧定义动作单元播放的 seq 范围——即使用目标部件的哪些状态,以及该动作在片段内的开始与结束位置。

How to do it in 3SAX V3

在 3SAX V3 中怎么做

1. Open the AG panel and bind a Material Group (SG).

1. 打开 AG 面板,绑定一个材质组(SG)。

2. Add an action unit and set the target part (join).

2. 添加动作单元,设置目标部件(join)。

3. Enter the seq range, e.g. 01:0-5 — 0 is the start frame, 5 is the end frame.

3. 填写 seq 范围,例如 01:0-5——0 是起始帧,5 是结束帧。

4. Or click auto-suggest sequence to generate a seq matching the target part's available states.

4. 或点击自动推荐序列,生成与目标部件可用状态匹配的 seq。

5. Set relative rotation, scale, X/Y offset, swap part, or trigger event for that unit.

5. 为该单元设置相对旋转、缩放、X/Y 偏移、替换部件或触发事件。

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

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

7. Save the action to LIBRARY for reuse.

7. 将动作保存到 LIBRARY 以便复用。

What you CAN and CANNOT do

能做与不能做

  • CAN: play only the frames you need, chain units into a state machine, trigger EVT events, reuse actions from the server library.
  • CANNOT: reference frames the target part does not have — validation shows a red hint with a fix example and the render fails.
  • CANNOT: leave required fields empty — the error list blocks the render.
  • 能做:只播放需要的帧,把单元串成状态机,触发 EVT 事件,从服务器库复用动作。
  • 不能做:引用目标部件没有的帧——输入框旁显示红色提示和修改示例,渲染失败。
  • 不能做:必填项留空——错误列表会阻止渲染。
