How to get animation Node data?

Anonymous — Wed, 18 May 2016 07:07:51 GMT

Hello, I have created an example code of what I wanted to do:

def FindAnimationNode( pParent, pName ):
    lResult = None
    for lNode in pParent.Nodes:
        if pName == lNode.Name:
            lResult = lNode
            break
    return lResult
    
lConstraintRelation = FBConstraintRelation( 'scripted1Relation' )
mltplyNode = lConstraintRelation.CreateFunctionBox( 'Number', 'Multiply (a x b)' )
gotAnimNode=FindAnimationNode(mltplyNode.AnimationNodeInGet(), 'b')
gotAnimNode.WriteData([100])

gotAnimNode#how do I get the Written Data 100?

I want to find a function that can return the 100 for me, but there's no getData function... any help is appreciated.

I've searched the forum, and seemed like there others who are looking for an answer for this as well, but no solution:

after quite some digging in the documentation, I found ReadData actually exist, but only in the C++ api like so:

bool  WriteData (double *Data, FBEvaluateInfo *pEvaluateInfo) 
  Write data to animation node. More...
 
  
bool  WriteGlobalData (double *Data, FBEvaluateInfo *pEvaluateInfo) 
  Write global data to animation node. More...
 
  
bool  ReadData (double *Data, FBEvaluateInfo *pEvaluateInfo) 
  Read data from animation node. More...
 
  
bool  ReadData (double *Data, FBTime pTime) 
  Read data from animation node. More...
 
  
bool  ReadData (double *Data)

I guess I hit the ultimate brick wall..
