[Closed] activate visibility track

I am creating a tool to animate several object visibility. My problem is I can’t activate the visibility track by script… anyone can do that?

BTW here is my script

– loran 2009 – – loran.cg@laposte.net
– visibility animator-
rollout visibility “::visibility::”
(

button addviztrack “Add visibility track to selection”
label blabla1 “———————————”
spinner fr1 “frame:” type:#integer range:[0,10000,1]
spinner viz1 “visibility:” type:#integer range:[0,1,0]
label blabla2 “———————————”
spinner fr2 “frame:” type:#integer range:[0,10000,10]
spinner viz2 “visibility:” type:#integer range:[0,1,1]

button btndoit”DO IT”width:100 height:35
button btnreset “Reset animation” width:100 height:15

–add visibility track for selected objects
on addviztrack pressed do
(for o in selection do
(
actionMan.executeAction 1 “640” – Doesn’t work please help!
)
)

–apply animation for selected objects
on btndoit pressed do
(
for o in selection do
(
with animate on
(
at time 0 o.visibility.controller.value = viz1.value
at time fr1.value o.visibility.controller.value = viz1.value
at time fr2.value o.visibility.controller.value = viz2.value
selectKeys o.visibility.controller 0 0f
deleteKeys o.visibility.controller #selection
)
)
)

-- clear all visibility frame for selected objects

on btnreset pressed do
(
for o in selection do
(
selectKeys o.visibility.controller 0 10000f
deleteKeys o.visibility.controller #selection
o.visibility.controller.value = 1
)
)
label blabla3 “———————————”
label blabla4 “::loran::”
)

createDialog visibility
