|
* ControlP5 Annotation
|
||
|
|
*
|
||
|
|
* Lately annotation support has been added to processing.
|
||
|
|
* Making use of annotations to create controllers is a great strategy i learned
|
||
|
|
* from Karsten Schmidt's (toxi) cp5magic library.
|
||
|
|
* Loving the simplicity of annotations and how it is aplied with cp5magic,
|
||
|
|
* i had to include it into controlp5 and the following example
|
||
|
|
* shows how to use annotations with controlp5.
|
||
|
|
*
|
||
|
|
* Annotations can be applied to variables and functions of the main program
|
||
|
|
* as well as individual classes. More details are included in the comments below.
