Q: In SuperMap iClient for javascript, when you use SuperMap.Animator to achieve animation effect, why is the animation speed always up and down? Using setSpeed() to adjust the playback speed has no effect?

A: The running speed of Animatoris determined by setSpeed and setFrameRate; the setSpeed() method can change the play speed, namely, the time interval between the data played each time. It refers to the time jump between user data played twice. The setFrameRate() method can change the frame rate, representing the number of times played per second.
