Hello.
I´m added a code that makes the leaves going down, look:

But, I want to repeat that same effect in the same location, because it only happens once. Could you help me?
I´m using this code:
Spoiler, click to toggle visibilty
[bg 0] ; Leaves - Front

type=normal
spriteno=0,4
start=10,40
delta=.342857,0.5
tile=1,0
tilespacing=420,0
mask=1
velocity=-0.5,0.3

scalestart=1,0.5
zoomdelta=0.5
[BGCtrlDef Pos2]
looptime=200
ctrlID=100
[bgctrl 0]
