public bool hasFixedDuration ;

Description

确定过渡的持续时间是以秒还是标准化时间为单位在固定的持续时间报告。

If hasFixedDuration is true, the transition duration is in seconds.

If hasFixedDuration is false, the transition duration is in normalized time.

Note: In normalized time, a duration of 1 makes the transition the same length as the state that triggered it. A value of 2, for instance, would make the transition twice as long as the state that triggered it.
