AxisCount: The number of available axes in Java Implement qrcode in Java AxisCount: The number of available axes

AxisCount: The number of available axes use jsp qr implementation togenerate qr code with java Microsoft .NET Buttons.Count(): The number of buttons. Buttons is an array of bool values, counting its members we can know the number of available buttons. In the CheckJoystick method, the first thing done was to update the input device status, calling the UpdateStatus method:. _joystick.Upda jvm qr barcode teStatus(); [ 202 ]. 6 . This method up QR Code 2d barcode for Java dates the values for the axis and the buttons properties to reflect the changes in the previously acquired input device. Then, we were able to check the values for the corresponding properties and we translated and rotated the spaceship according to them. The Buttons array"s lower bound is 0.

Therefore, in order to check the bool value for the button number 11, we used Buttons[10]. A true value means that the button is pressed. We checked for buttons number 11 and 12 and translated the spaceship according to their states:.

if (_joystick. Buttons[10] translateShip.OffsetX if (_joystick.

Buttons[11] translateShip.OffsetX == += == -= true) 0.05f; true) 0.

05f;. The steering w tomcat QR Code 2d barcode heel movement affects the AxisC property as previously explained. We took into account the value that ranges from 0 to 65535 to create a 360 degrees rotation:. rotateShip.Ang le = ((_joystick.AxisC / 65535f) * 360);.

We also rotate QRCode for Java d the spaceship in its Y axis taking into account the acceleration and brake pedals that affect the AxisD property, creating a 360 degrees rotation:. rotateShipY.An gle = ((_joystick.AxisD / 65535f) * 360);.

You can control any aspect of the game checking the values for the available axes and buttons. Working with many input devices Sometimes, we applet qr bidimensional barcode need to work with many joystick style game input devices at the same time. For example, we can work with two gamepads, one flightstick and a gamepad, one steering wheel and two gamepads, etc. We can do this using the Joystick class analyzing the strings returned when calling its FindJoysticks function.

Then, we can call the AcquireJoystick method for each gaming input device that we need to control. We need one instance of the Joystick class per device..

[ 203 ]. Controlling Input Devices to Provide Great Feedback Using other input devices We can use the qr codes for Java same principles explained for the steering wheel to take full advantage of the features offered by a gamepad, joystick, flightstick, and any other input gaming devices that provide a certain number of buttons and digital and/or analog sticks. The only difference will be the features reported by each device and the experience provided to the player..

When using Dir ectInput in an XBAP WPF application, it is convenient to deactivate the keyboard and mouse mode for the gamepad or other gaming input devices. We can take full advantage of their analog modes..

Have a go hero using the Wiimote You can use th e most exciting input gaming devices, such as the amazing Nintendo"s Wiimote, adapting existing wrappers to an XBAP WPF application, as we did for the Joystick class. There is a managed library to use the Wiimote in Windows with the C# code, developed by Brian Peek (http://www.brianpeek.

com). You can download it from http://wiimotelib.codeplex.

com/. Your project manager wants you to control the spaceship using a Wiimote. You have to adapt this wrapper to use it in the game and change the game loop to take the values from the Wiimote.

It must move and rotate the ship as we did for the steering wheel.. Have a go hero working with time, analog and digital values Your project m anager is delighted with the steering wheel that controls the spaceship. The game loop used in the XBAP WPF application takes into account the elapsed time between each rendered frame. However, this value is not used to bring more precision to the movements and rotations.

You have already worked with 2D games taking into account the elapsed time. Now, it is time to do this in the 3D games. Offer the player the possibility to translate the spaceship and rotate it taking into account the values from the gaming input devices and the elapse time.

Then, accelerate and decelerate the spaceship"s speed according to the values read from analog inputs. Use an object-oriented design to provide these new features to the spaceship..
