Constant Holds the values at the ends of the range for all frames. Use Constant
when you want no animated effect before or after the range. The time value
at start of the range is held for all frames before the range, and the time value
at the end of the range is held for all frames after the range. Constant is the
default out-of-range type for multiplier curves.
Cycle Repeats the same animation as within the range. Use Cycle when you
want an animation to repeat exactly.
Loop Repeats the same animation as within the range but interpolates between
the last key and the first key of the range to create a smooth loop. Use Loop
with an extended range bar to produce smoothly repeating animation.
Ping Pong Alternates between forward and backward repetition of the
animation within the range. Use Ping Pong when you want your animation
to alternate back and forth.
Linear Projects the animation value along lines tangent to the ease or
multiplier curve at the limits of the range. Use Linear when you want the
animation to enter and leave the range at a constant velocity.
Relative Repeat Repeats the same animation as within the range but offsets
each repetition by the value at the end of the range. Use Relative Repeat to
create animations that build on each other as they repeat.
