Good point. I have added the following method to
AnimationControl:
public int getCurrent()
It returns the ordinal step number of the current
animation step. You can get the Time value as
follows:
int current = animation_control.getCurrent();
float[][] values
animation_control.getSet().indexToValue(new int[] {current});
float time_value = values[0][0];
Note that AnimationControl.getSet() returns the
(1-D) Set of samples of Time (or whatever RealType
is mapped to Animation) associated with animation
steps.
