Phaser API Documentation

Description:

Retrieves a value from an object, or an alternative object, falling to a back-up default value if not found.

The key is a string, which can be split based on the use of the period character.

For example:

const source = {
  lives: 3,
  render: {
    screen: {
      width: 1024
    }
  }
}

const lives = GetValue(source, 'lives', 1);
const width = GetValue(source, 'render.screen.width', 800);
const height = GetValue(source, 'render.screen.height', 600);

In the code above, lives will be 3 because it's defined at the top level of source. The width value will be 1024 because it can be found inside the render.screen object. The height value will be 600, the default value, because it is missing from the render.screen object.
