|
|
This template handles value accumulation across repeated
|

effect runs: returned is the end value times the repeat
|
|
count, plus the current value.

|
@param rEndValue
|
|
End value of the simple animation.

Number of completed repeats (i.e. 0 during the first

effect run)

|
|
Current animation value
