public interface ActionListener extends InputListener
ActionListeneris used to receive input events in "digital" style.
Generally all button inputs, such as keyboard, mouse button, and joystick button, will be represented exactly. Analog inputs will be converted into digital.
When an action listener is registered to a natively digital input, such as a button,
the event will be invoked when the button is pressed, with
true, and will be invoked again when the button is released,
value set to
void onAction(java.lang.String name, boolean isPressed, float tpf)
name- The name of the mapping that was invoked
isPressed- True if the action is "pressed", false otherwise
tpf- The time per frame value.
