To render two copies of a complex shape in KineticJS, you can follow these steps:

  1. Create the complex shape using KineticJS. This can be done by instantiating a Kinetic.Shape object and specifying the desired properties for the shape, such as its fill color, stroke color, line width, etc.
  2. Once you have created the complex shape, you can then create two copies of it by using the clone() method. This method creates a deep copy of the shape, including all its properties and children.
  3. You can then position the two copies of the shape on the stage by setting their x and y coordinates to the desired values.
  4. Finally, add the two copies of the complex shape to a Kinetic.Layer object and add the layer to the Kinetic.Stage object to render them on the stage.


Here is an example code snippet to demonstrate how to render two copies of a complex shape in KineticJS:

// Create the first complex shape
var shape = new Kinetic.Shape({
  fill: 'blue',
  stroke: 'black',
  strokeWidth: 2,
  sceneFunc: function(context) {
    // define the complex shape here
  }
});

// Create two copies of the shape
var shapeCopy1 = shape.clone();
var shapeCopy2 = shape.clone();

// Position the two copies on the stage
shapeCopy1.setAttrs({
  x: 50,
  y: 50
});

shapeCopy2.setAttrs({
  x: 150,
  y: 150
});

// Add the shapes to a layer
var layer = new Kinetic.Layer();
layer.add(shapeCopy1);
layer.add(shapeCopy2);

// Add the layer to the stage
var stage = new Kinetic.Stage({
  container: 'container',
  width: 500,
  height: 500
});
stage.add(layer);


This code snippet creates two copies of a complex shape and positions them at different locations on the stage. The shapes are then added to a layer and the layer is added to the stage to render the shapes on the screen.
