View Full Version : Slider on change Event + Math + Logical Question

 abyjoe05-06-2009, 12:26 PMI am using a slider where I set the range on the fly (through a variable) myLayers = #(1,2,3,4,5,6,.....n) -- (This is calculated when the script runs) mySlider.range = [0, myLayers.Count*5, 0] mySlider.ticks = 5 Now lets say myLayers.count = 6. In this case the range will be 6*5 = 30... And with Ticks = 5 it will take 6 ticks to reach the range which is equal to myLayers.count. In the "on Slider Changed Val" event I want play with each myLayers element visibility... So when the value of spinner is between 0-5 I want to increase the visibility of 1st element of myLayers from 0 to 100... when the value of spinner is betweek 5-10 I want to increase the visibility of Second element from 0 to 100... and so on. This is what I cant quite put down correctly... any help will probably save me tons of hours. thanks

Here is a quick example:

try (destroyDialog rollname) catch ()
rollout rollname "rollout"
(
spinner spNumLayers "num layers:" type:#integer range:[1,20,6]
slider slTest "test"
spinner spCurrentLayer "current layer:" enabled:false type:#integer range:[1,20,1]
spinner spVis "visibility:" enabled:false range:[0,100,0]

fn setTickes =
(
slTest.ticks = spNumLayers.value
)

fn getCurrentLayer =
(
spCurrentLayer.value = if slTest.value < 100 then
1 + spNumLayers.value * slTest.value / 100 as integer
else
spNumLayers.value
)

fn getVisibility =
(
local part = 100.0 / spNumLayers.value
spVis.value = if slTest.value < 100 then
100 * (mod slTest.value part) / part
else
100
)

fn updateUI =
(
getCurrentLayer()
getVisibility()
)

fn init =
(
setTickes()
)

-- Event Handlers
------------------------------------------

on spNumLayers changed val do setTickes()
on slTest changed val do updateUI()
on rollname open do init()

) -- end of rollout

createDialog rollname width:200

i have run into a problem... although my script now works but its behaving in a wierd way

The visibility wont update on all objects when I am looking at only a Shaded View in viewport i.e. without wireframes.. But if I have wireframe + shaded it works fine....

How can I fix that?
