Simple Question (I think)

Troubleshooting General Help
1

I'm using BasicGameState for Standard game, and I wanna know how can I retrieve my Inputs, so I can do, for i.e:


input.addAction(accelAction, InputHandler.DEVICE_KEYBOARD, KeyInput.KEY_U, InputHandler.AXIS_NONE, false);



Thank you :D

There are many ways.

You could use Gamecontrols / GamecontrolManager.

take a look at http://code.google.com/p/jmonkeyengine/source/browse/trunk/src/jmetest/input/controls/TestControls.java

So, Core-Dump, I have a question about TestControls.java. I can see in the code the part that sets up the Controls, but not the part that says what to do when use that command. Can you it show me?

The GameControl system is quite flexible and easy to work with and extend.



The ThrottleController and RotationController are predefined Controllers, you pass the GameControls you defined, and the controller rotates your object.



In the example also a ActionChangeController is used, where you just implement the changed() Method.

           ActionChangeController quit = new ActionChangeController(exit, new ControlChangeListener() {
                        public void changed(GameControl control, float oldValue, float newValue, float time) {
                                if (newValue == 1.0f) {
                                        game.shutdown();
                                }
                        }
            });



An example using ActionController which has a pressed / released event:

        // Lock target
        manager.addControl("lockTarget").addBinding(new KeyboardBinding(KeyInput.KEY_L));
        ActionController lockTargetController = new ActionController (manager.getControl("lockTarget"), new GameControlAction() {
            public void pressed(GameControl control, float time) {
                targetDevice.toggleLock();
            }
            public void released(GameControl control, float time) {
            }
        });
        node.addController(lockTargetController);



There is also ActionRepeatController where you can pass a Runnable and a rate at which the Runnable is executed as long as the GameControl you defined is active.

I tried to do what you said, so at my BasicGameState init method, I call the method 'configureControls()':


public void configureControls() {
        GameControlManager manager = new GameControlManager();
        GameControl forward = manager.addControl("forward");
        forward.addBinding(new KeyboardBinding(KeyInput.KEY_W));

        ActionController forwardController = new ActionController (manager.getControl("Forward"), new GameControlAction() {
            public void pressed(GameControl control, float time) {
                pivotNode.getWorldRotation().mult(lookingDirection, lookingDirection);
                walkDirection.addLocal(lookingDirection);
                character.setWalkDirection(walkDirection);
            }

            public void released(GameControl control, float time) {
         
            }
        });
        pivotNode.addController(forwardController);
    }



But I get a exception in 'main':

Exception in thread "main" java.lang.NullPointerException
        at jme.game.SimpleGameState.configureControls(SimpleGameState.java:107)
        at jme.game.SimpleGameState.init(SimpleGameState.java:84)

addControl("forward");

getControl("Forward"),



:slight_smile:



you could use  enum's or constants to avoid such typos
