A NULL OP callback function.

This function always returns null.

Used internally by Phaser when it's more expensive to determine if a callback exists than it is to just invoke an empty function.

GetAdvancedValue

<static> GetAdvancedValue(source, key, defaultValue)

Description:

Retrieves a value from an object. Allows for more advanced selection options, including:

Allowed types:

Explicit: { x: 4 }

From function { x: function () }

Randomly pick one element from the array { x: [a, b, c, d, e, f] }

Random integer between min and max: { x: { randInt: [min, max] } }

Random float between min and max: { x: { randFloat: [min, max] } }

Parameters:

Returns: * - The value of the requested key.

Source: src/utils/object/GetAdvancedValue.js#L10
Since: 3.0.0

GetFastValue

<static> GetFastValue(source, key, [defaultValue])

Description:

Finds the key within the top level of the source object, or returns defaultValue

Parameters:

Returns: * - The value if found; otherwise, defaultValue (null if none provided)

Source: src/utils/object/GetFastValue.js#L7
Since: 3.0.0

GetMinMaxValue

<static> GetMinMaxValue(source, key, min, max, defaultValue)

Description:

Retrieves and clamps a numerical value from an object.

Parameters:

Returns: number - The clamped value from the source object.

Source: src/utils/object/GetMinMaxValue.js#L10
Since: 3.0.0

GetValue

<static> GetValue(source, key, defaultValue, [altSource])

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:

Copyconst 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.

Parameters:

Returns: * - The value of the requested key.

You can also use it to pad numbers (they are always returned as strings):

pad(512, 6, '0', 1)

If you don't specify a direction it'll pad to both sides:

pad('c64', 7, '*')

Would return: **c64**
