 For an example (and a highly usable implementation) of generating interfaces from the annotations you are encouraged to check out [`orx-gui`](../orx-gui/README.md).

+Currently orx-parameters facilitates the following annotations:
 
  - `DoubleParameter` for `Double` properties
  - `IntParameter` for `Int` properties
  - `BooleanParameter` for `Boolean` properties
  - `TextParameter` for `String` properties
  - `ColorParameter` for `ColorRGBa` properties
+ - `XYParameter` for `Vector2` properties
+ - `Vector2Parameter`  for `Vector2` properties
+ - `Vector3Parameter` for `Vector3` properties
+ - `Vector4Parameter` for `Vector4` properties
 
 Additionally there is an `ActionParameter` that can be used to annotate functions without arguments.
