Custom script: Reading a string and changing arrangement of objects

  Hi,

  Apologies for the code dump. I’m trying to align letter-shaped chain links into a circle. This script works great for alignment (it counts the letters in ‘BraceletString’) but it doesn’t respond to configuration changes made by the website. Do I have to do some sort of async function? I followed the example in the docs as a template but I think there might be something I’m missing.

  //Get api data
  const config = api.configurator.getConfiguration();
  
  const pi = 3.14159265359;
  //get string info
  const stringInput = config[’BraceletString’]
  const num = stringInput.length
  
  if(num > 20){
     num = 20;
  }
  
  //per-link rotational offset in degrees
  const rot = 360/num;
  //radius of the arranged circle
  const spc = ((num * 1) / pi) * .5
  
  function circleAlign(){
  
     //for each link (named letter1, letter2, ... letterN)
     for (let i = 1; i < 21; i++) {
        //move out to radius distance
        api.scene.set({
              from: api.instanceId,
              name: ’letter’ + i.toString(),
              plug: ’Transform’,
              property: ’translation’,
           }, { 
              x: 0, 
              y : 0,
              z: 1 * spc
           }
        );
  
        //set pivot point to (0,0,0)
        api.scene.set({
              from: api.instanceId,
              name: ’letter’ + i.toString(),
              plug: ’Transform’,
              property: ’localRotatePivot’,
           }, { 
              x: 0, 
              y : 0,
              z: -1 * spc
           }
        );
  
        //rotate by specified offset
        api.scene.set({
              from: api.instanceId,
              name: ’letter’ + i.toString(),
              plug: ’Transform’,
              property: ’rotation’,
           }, { 
              x: 0,
              y : rot * i, 
              z: 0
           }
        );
     }
  }
  
  function straightAlign(){
  
     //for each link (named letter1, letter2, ... letterN)
     for (let i = 1; i < num + 1; i++) {
  
     //set pivot point to (0,0,0)
        api.scene.set({
           from: api.instanceId,
           name: ’letter’ + i.toString(),
           plug: ’Transform’,
           property: ’localRotatePivot’,
        }, { 
           x: 0, 
           y: 0,
           z: 0
           }
        );
        //rotate by specified offset
        api.scene.set({
           from: api.instanceId,
           name: ’letter’ + i.toString(),
           plug: ’Transform’,
           property: ’rotation’,
        }, { 
           x: 0,
           y: 0, 
           z: 0
        }
        );
     
        //move out to radius distance
        api.scene.set({
              from: api.instanceId,
              name: ’letter’ + i.toString(),
              plug: ’Transform’,
              property: ’translation’,
           }, { 
              x: i - (num * 0.5),
              y: 0,
              z: 0
           }
        );
     }
  }
  
  //TODO: make these inivisible instead of moving them out of frame
  function hideUnused(){
  
     if(num >= 20){
        return;
     }
  
     for (let i = num + 1; i < 21; i++) {
        api.scene.set({
           from: api.instanceId,
           name: ’letter’ + i.toString(),
           plug: ’Transform’,
           property: ’translation’,
        }, { 
           x: 100,
           y: 100,
           z: 100
        }
     );
     }
  }
  
  function setCamera(camName){
     // id = api.scene.findNode({
     //    from:api.instanceId,
     //    name: camName,
     // });
  
     // api.setActiveCamera(id)
     config[’CurrentCam’] = camName
     api.configurator.setConfiguration(config)
  }
  
  if(num > 8){
     circleAlign()
     setCamera(’OrbitCam’)
  }else{
     straightAlign()
     setCamera(’FixedCam’)
  }
  
  hideUnused()
  

  For reference, this is the website test:

   

  

  The string asset should change to ‘isNotShowingUpInTheConfig’ but instead the string stays blank

  Hi Andrew,

  I haven’t looked through your script extensively but I believe the issue your having is that in your embed ‘Attribute Name’ should be replaced with the name of the part reference attribute you’re using.

  hope this helps, Ian

  Well this is embarrassing! I expected it to be a structural problem and it was something pretty basic. It works now. Thanks for the help.

  initialConfiguration: {
           ’BraceletString’: ’andrewq’
            },
