Hey guys, im looking to create a spinner that controls the maximum value of a slider. I’ve got it all working except for one thing: the Slider will not Update when you enter a new value. You have to deselect the item and reselect it for it to work. I cannot figure out how to update it as you go.
Here is the script as it stands.
-- FoaS 3-Point Lighting Rig
-- v: 0.1a
plugin modifier ThreePointControls
name: "FoaS 3-point Rig v0.1a"
classID:#(0x492d55d4, 0x363e8221)
(
parameters main rollout:controls
(
'KeyInt' ui:key_sld type:#float default:0
'FilInt' ui:fil_sld type:#float default:0
'BakInt' ui:bak_sld type:#float default:0
'KeyCol' ui:key_pkr type:#color default:(color 255 255 255)
'FilCol' ui:fil_pkr type:#color default:(color 255 255 255)
'BakCol' ui:bak_pkr type:#color default:(color 255 255 255)
'Keymax' ui:key_spn type:#float default:1
)
rollout Controls "Light Console" width:160 height:300
(
slider key_sld "Key" range:[0,Keymax,0] orient:#vertical ticks:0 pos:[10,50] width:40 height:100 enabled:true
slider fil_sld "Filler" range:[0,1,0] orient:#vertical ticks:0 pos:[60,50] width:40 height:100 enabled:true
slider bak_sld "Kicker" range:[0,1,0] orient:#vertical ticks:0 pos:[110,50] width:40 height:100 enabled:true
spinner key_spn "" range:[0,100,keymax] pos: [10,160] width:40
colorpicker key_pkr "" pos:[10,10] width:40 height:40 color:((color 255 255 255))
colorpicker fil_pkr "" pos:[60,10] width:40 height:40 color:((color 255 255 255))
colorpicker bak_pkr "" pos:[110,10] width:40 height:40 color:((color 255 255 255))
)
on key_spn changed val do
(
key_sld.range.y = val
if (val > keyint.value) then (keyint.value = value))
)
Once again, the problem is the slider will not update automatically until you descelect the item and reselect it. Furthermore the actual light will not change to suit until you move the slider.
Your problem is the syntax, not so much the logic.
First of all, event handlers of rollout controls MUST be inside the rollout definition, not in the plug-in body.
Then, the parameters from a paramblock2 do not have a .value property, they are values already.
Lastly, if the current value of the slider is greater than the top limit, you will have to bump it down, not the other way round. You can do this to either the parameter or its UI element – both will work.
rollout Controls "Light Console" width:160 height:300
(
...
colorpicker bak_pkr "" pos:[110,10] width:40 height:40 color:((color 255 255 255))
--move handler inside the rollout
on key_spn changed val do
(
key_sld.range.y = val --set the top range
if KeyInt > val do KeyInt = val --if value is greater than top limit, bump it down.
--if key_sld.value > val do key_sld.value = val --ALTERNATIVE, DOES THE SAME
)
)
Thank you Bobo, as always you are a saint.
I owe you a beer.
