World#setProperty()

setProperty(child, key, value, operation, force) → {boolean}

Sets a property to the given value on the child. The operation parameter controls how the value is set.

The operations are:

  • 0: set the existing value to the given value; if force is true a new property will be created if needed
  • 1: will add the given value to the value already present.
  • 2: will subtract the given value from the value already present.
  • 3: will multiply the value already present by the given value.
  • 4: will divide the value already present by the given value.
