Eliminating elements from a KineticJS layer

I'm currently tackling a KineticJS project where I need to constantly create and delete shapes. However, I'm struggling with figuring out how to properly delete these shapes. I've been attempting to use the code snippet below:

$ myLayer.remove(myShape)

Despite numerous recommendations in various posts, the documentation indicates that this code will actually remove the layer from the stage rather than the shape from the layer. When I tested it in my project, it indeed removed the layer from the stage.

Am I missing something here or is there an alternative method to remove a shape from a layer?

Answer №1

Here are two useful functions that you can use:

  • childContainer.remove() function removes the childContainer from its parent.
  • parentContainer.removeChildren() function removes all the children from the container.

Note: This technique can also be applied to shapes. Just refresh or redraw the layer.

myShape.remove();
myLayer.draw();

Answer №2

After upgrading from Kinetic 4.0 to the most recent version, I encountered an issue where remove(child) was no longer functioning as expected. Even removeChild(child) failed to work.

To fix this problem, I successfully used child.remove(); instead.

Answer №3

To utilize the kinetic function prototype, you can use the following syntax:

Kinetic.Node.prototype.remove.call(removed_object);

baselayer.draw();
