Let's see how we can add the functionality to pick up and place blocks. The following fig-
ure is of a resulting terrain block:
1. Begin in
CubeWorldAppState
by implementing
ActionListener
to
handle user input. Add a
CubeCell
field called
takenCube
to store a
CubeCell
field that has been picked up.
2. Add mappings to
inputManager
to pick up and place a
CubeCell
field. Use
the left and right mouse button as shown in the following lines of code:
inputManager.addMapping("take", new
MouseButtonTrigger(MouseInput.BUTTON_LEFT));
inputManager.addMapping("put", new
MouseButtonTrigger(MouseInput.BUTTON_RIGHT));
