### [ScriptGraph] GetInputValue from an input node

Posted:

**Mon Jul 23, 2018 8:24 am**Hello,

Sorry for this noob question. I tried to find as much information as I can about how to do this. I though I understood it but I keep getting errors, so I'm requesting your help.

What I'm trying to achieve:

Using a Transform Scale node to randomize some transformation I'm doing.

It was working well using a basic float input like I'm doing for the translation and rotation. But I wanted the possibility to lock the 3 values together like we have with a Transform scale.

However, I'm having trouble accessing the float values of the Transform Scale node

I'm not pasting the entire code but just the areas that concern my issue.

It was perfectly working until I tried to improve a bit my script.

At this line:

What I'm trying to store in this variable is an array of value like I can get with my randTrans and randRot variables.

I tried a lot of different syntax and combination without success.

The error on this one is

Thank you very much for your help!

- Code: Select all
`function ScriptGraph.onInit(self, graph)`

local inputs = self:setInputLinkers(

{

{

label = "Random Translation",

type = octane.PT_FLOAT,

defaultNodeType = octane.NT_FLOAT,

defaultValue = { 0, 0, 0 },

sliderBounds = { 0, 1 },

logarithmic = true,

},

{

label = "Random Rotation",

type = octane.PT_FLOAT,

defaultNodeType = octane.NT_FLOAT,

defaultValue = { 0, 0, 0 },

sliderBounds = { 0, 1 },

logarithmic = true,

},

{

label = "Random Scale",

type = octane.PT_TRANSFORM,

defaultNodeType = octane.NT_TRANSFORM_SCALE,

defaultValue = { 0, 0, 0 },

sliderBounds = { 0, 10 },

logarithmic = true,

},

{

label = "Seed",

type = octane.PT_INT,

defaultNodeType = octane.NT_INT,

defaultValue = { 1 },

sliderBounds = { 1,1000 },

logarithmic = true,

},

})

IN_TRANSLATION_RAND = inputs[1]

IN_ROTATION_RAND = inputs[2]

IN_SCALE_RAND = inputs[3]

IN_SEED = inputs[4]

local randTrans = self:getInputValue(IN_TRANSLATION_RAND)

local randRot = self:getInputValue(IN_ROTATION_RAND)

local randScale = self:getConnectedNode(IN_SCALE_RAND):getInputValue(octane.P_SCALE)
