animInfo.normalizedTime  Animation State Standardization time , An animation value is from 0~1. To 1 Then the animation is played

animInfo.IsName("Take 001")  Currently playing animation ,Take 001 Is the name of the animation

principle ： First of all, you should know the end frame of each animation , Then the end frame of the animation is divided by the total frame to get the end frame at animInfo.normalizedTime  Value , Finally, pause the animation as a condition , Continue to play the animation to realize the start and stop of the next animation .

such as ： There is an animation 100 frame , No editing , Need to play multi segment animation .

It is known that the end frame of the first paragraph is 20 frame , that 20/100=0.2,0.2 Then for normalizedTime Value as animation pause condition （ You can set a range when writing conditions ）.
