Hi,

I've googled my ass off, thought this was easy to find:

When writing a float script controller for some property of an object, how can you reference the object itself? I know you can use $instance_name if you know the name, but I want to write the controller script once, and copy the object multiple times, and don't want all to reference only the source object.

In my case, I have a light, and assigned a script controller to its intensity value. Somewhere in the script I need to get the position of the light the controller is for.

add the light as a node variable and use variableName.pos

add the light as a node variable and use variableName.pos
But then, when I copy the light, will the variable reference the source or the destination of the copy?

NM: I noticed I was lazy to ask and not just try ;). The variables references the new object, exactly what I want, thanks man!

hey, take a deep look into MXS helpīs Interface: IScriptCtrl

simple test:



-- create the light
theLight = omniLight name:"light_omni" multiplier:200 rgb:(color 255 255 0) pos:[0,0,20]

-- add the CA
CA = attributes CustomCA
(
parameters mainP
(
script type:#float animatable:true
)
)
custAttributes.add theLight CA

-- create the float script
FS = float_script()
FS.addNode "theLight" theLight
FS.SetExpression "theLight.multiplier = 200"

--add the float script to the light CA
theLight.baseObject.CustomCA.script.controller = FS


notice the variable will auto-update when you copy the light multiple times.

hope it helps.
