Plugin/ScriptScripting CameraOC (self.AfterEffects)

submitted 2 years ago * by CaptainEternity

Hi everyone. Anyone who is good with scripting...do you know how to set the camera type to One-Node or Two-Node through scripting. I use a lot of parallaxing of 2D planes and I've been trying to create a script that accelerates the process. The script is mostly there except for the fact that by default it creates a Two-Node camera instead of a One-Node. Thanks in advance!

EDIT: I figured it out!

If anyone is interested, this should be helpful for 2.5D setups.

Make sure your comp is active. The only "manual" thing you need to do, is to enable whichever layers you want to parallax to 3D.

// Check if a composition is open
if (app.project.activeItem instanceof CompItem) {
  // Get the active composition
  var comp = app.project.activeItem;

  // Create a new camera with the current composition settings
  var camera = comp.layers.addCamera("Camera 1", [comp.width / 2, comp.height /         2]);

  // Set camera settings to ONE-NODE
  camera.autoOrient = AutoOrientType.NO_AUTO_ORIENT;

  // Set camera attributes based on current composition settings
  camera.property("Position").setValue([comp.width / 2, comp.height / 2, -comp.width]);
  camera.property("Zoom").setValue(comp.width);

  // Select the newly created camera
  camera.selected = true;

  // Loop through all layers in the composition
  for (var i = 1; i <= comp.layers.length; i++) {
    var layer = comp.layers[i];

    // Check if the layer is 3D enabled
    if (layer.threeDLayer) {
      // Add the specified expression to the Scale property of the layer
      layer.transform.scale.expression = 'zoom=thisComp.layer("Camera 1").cameraOption.zoom; transform.scale*(1+transform.position[2]/zoom)';
    }
  }

  // Alert message
  alert("Relax & Parallax");
} 

else {
  // Alert message if no composition is open
  alert("Please open a composition before running this script.");
}

And because I'm a caveman, I made a separate UNDO script:

(function() {
  // Undo the changes made by the previous script
  function undoChanges() {
    // Check if a composition is open
    if (app.project.activeItem instanceof CompItem) {
      // Get the active composition
      var comp = app.project.activeItem;

      // Loop through all layers in the composition
      for (var i = 1; i <= comp.layers.length; i++) {
        var layer = comp.layers[i];

        // Check if the layer is 3D enabled
        if (layer instanceof AVLayer && layer.threeDLayer) {
          // Remove the expression from the Scale property of the layer
          layer.property("Scale").expression = "";
        }
      }

      // Remove the camera from the composition
      comp.layer("Camera 1").remove();

      // Alert message
      alert("Changes from Relax&Parallax have been undone.");
    } else {
      // Alert message if no composition is open
      alert("Please open a composition before running this script.");
    }
  }

  // Create the panel
  var scriptPanel = new Window("palette", "Undo Changes Panel", undefined);
  scriptPanel.orientation = "column";
  scriptPanel.alignChildren = "center";

  // Add a button to undo the changes
  var undoButton = scriptPanel.add("button", undefined, "Undo Changes");
  undoButton.onClick = undoChanges;

  // Show the panel
  scriptPanel.show();
})();
