TheLinearcontrollerinterpolatesbetween
animation keys by evenly dividing the change from
onekeyvaluetothenextbytheamountoftime
between the keys.
Linear controllers do not display a properties
dialog. The only information stored in a linear key
are the time and animation values.
Use Linear controllers whenever you want a very
regular, even transition from one key to the next.
Forexample,useaLinearcontrollerfor:
