Working with Sprite Sheets / Note On

[SonoLuminus]

I'm trying to animate a sprite sheets (png) where the animation is triggered and disabled with Note on information. I've done this in Kontakt many times with a custom script that looks something like this:

DECLARATION
declare $i
declare $wait
declare $run
declare $playing
declare $speed
declare $center
declare $ease_out
declare $animation_width := 0
$center := (275-$animation_width)
declare ui_label $animation(1, 1)

set_control_par_str(get_ui_id($animation),$CONTROL_PAR_PICTURE,"animation_noteon")
set_control_par(get_ui_id($animation),$CONTROL_PAR_PICTURE_STATE,0)
set_control_par(get_ui_id($animation),$CONTROL_PAR_WIDTH,$animation_width)
set_control_par(get_ui_id($animation),$CONTROL_PAR_HEIGHT,100)
set_control_par(get_ui_id($animation),$CONTROL_PAR_POS_X,$center+33)
set_control_par(get_ui_id($animation),$CONTROL_PAR_POS_Y,50)

CONTROL
function animation
$i := 0
while ($run=1)
$playing := 1
set_control_par(get_ui_id($animation),$CONTROL_PAR_PICTURE_STATE,$i)
inc($i)
if ($i=90)
$i := 0
end if
wait($wait)
end while
end function

on note
$speed := 10+($EVENT_NOTE/2)+($EVENT_VELOCITY/10*2)
$wait := 1000000/$speed

$ease_out := 0
$run := 1
if ($playing=0)
call animation
end if
end on

on release
if (search(%KEY_DOWN,1)=-1)
$ease_out := 10
else
$ease_out := 0
end if
while (search(%KEY_DOWN,1)=-1 and ($ease_out>0))
dec($ease_out)
dec($speed)
$wait := 1000000/$speed+1
if ($ease_out=0)
$playing := 0
$run := 0
end if
wait($wait)
end while

Can someone direct me to any comparable HISE callbacks, snippets or expressions that may get me headed in the proper direction? I've been able to create a knob using the my sprite sheet but I have not determined the best way to trigger the animation using any NoteOn functions.

Thanks in advance for your comments and replies!

There is no wait statement in HISE. Instead you should use the timer callback.
