|
* ControlP5 Basics
|
|
*
|
|
* The following example demonstrates the basic use of controlP5.<br />
|
|
* After initializing controlP5 you can add controllers to controlP5.
|
|
* Here we use three numberboxes, one slider and one textfield.
|
|
* The numberbox with name numberboxC will trigger function numberboxC()
|
|
* in the example below. Whenever controlP5 detects a function in your
|
|
* sketch that corresponds to the name of a controller, it will forward
|
|
* an event to that function. Any event triggered by a controller
|
|
* will be forwarded to function controlEvent in your sketch.
|
|
* related examples ControlP5numberbox, ControlP5slider, ControlP5textfield
