Class 3 Input Handling
Inclass Keyboard input demo
KeyboardState keyboardState = Keyboard.GetState();
Explore Limitations of Built in Keyboard state.
Input
input from Game Controller and Keyboard
GamePad
XNA has built in support for up to 4 game controllers. The default controller is a x-box controller. X-Box Controller The Controller is accessed through the GamePad Object and the GamePadState Structure reference types
//Get an instance of the gamePadState Structure
GamePadState gamePad1State = GamePad.GetState(PlayerIndex.One);
/*Since the Keyboard structure is Windows only we
need to use some preprocessor
directives to only compile the KeyBoard
state code if the target is not XBOX360 (I
should also add zune if this is one of our build targets)
*/
#if !XBOX360
#region KeyBoard
KeyboardState keyboardState = Keyboard.GetState();
#endif

Input Error missing DirectX9
Error:An unhandled exception of type 'System.DllNotFoundException' occurred in SharpDX.XInput.dll Additional information: Unable to load DLL 'xinput1_3.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E)
XInput library may be missing if you have a fresh install of win8.1 or 10
Solution: Install DirectX 9 Runtime http://www.microsoft.com/en-us/download/confirmation.aspx?id=8109 or http://www.microsoft.com/en-us/download/details.aspx?id=35
Unity Basics and Movement
Demo add Art and setup folders
Movement script
parameter
public Vector3 Direction = new Vector3(1, 0, 0);
public float Speed = 5;
Update
void Update () {
//Move Pacman
this.transform.position += this.Direction * this.Speed * Time.deltaTime;
}
Full Script with wall bouncing
using UnityEngine;
using System.Collections;
public class SimpleMove : MonoBehaviour {
public Vector3 Direction = new Vector3(1, 0, 0);
public float Speed = 5;
static Vector3 cameraBottomLeft; //calculate camera left
static Vector3 cameraTopRight; //calculate camera top
static Rect cameraRect; //rectangle for camera
// Use this for initialization
void Start () {
cameraBottomLeft = Camera.main.ScreenToWorldPoint(Vector3.zero);
cameraTopRight = Camera.main.ScreenToWorldPoint(new Vector3(
Camera.main.pixelWidth, Camera.main.pixelHeight));
cameraRect = new Rect(
cameraBottomLeft.x,
cameraBottomLeft.y,
cameraTopRight.x - cameraBottomLeft.x,
cameraTopRight.y - cameraBottomLeft.y);
}
// Update is called once per frame
void Update () {
//Move Pacman
this.transform.position += this.Direction * this.Speed * Time.deltaTime;
if (!cameraRect.Contains(this.transform.position))
{
//keep on screen
if (this.transform.position.x <= cameraRect.xMin)
{
this.Direction.x *= -1;
}
if (this.transform.position.x >= cameraRect.xMax)
{
this.Direction.x *= -1;
}
if (this.transform.position.y > cameraRect.yMax)
{
this.Direction.y *= -1;
}
if (this.transform.position.y < cameraRect.yMin)
{
this.Direction.y *= -1;
}
}
}
}
and Input from keyboard
using UnityEngine;
using System.Collections;
public class SimpleInput : MonoBehaviour {
public Vector3 Direction;
public float Speed;
public Vector3 keyDirection;
// Use this for initialization
void Start () {
}
// Update is called once per frame
void Update () {
//input
//direction.x = direction.y = 0;
keyDirection.x = keyDirection.y = 0;
//Keyboard
if (Input.GetKey("right"))
{
keyDirection.x += 1;
}
if (Input.GetKey("left"))
{
keyDirection.x += -1;
}
if (Input.GetKey("up"))
{
keyDirection.y += 1;
}
if (Input.GetKey("down"))
{
keyDirection.y += -1;
}
Direction += keyDirection;
Direction.Normalize();
//Move Pacman
this.transform.position += this.Direction * this.Speed * Time.deltaTime;
}
}
Homework
Moving Game 2 Interesting movement (Mono Game and Unity)
Update your moving assigment to make the movement more interesting. Use more than 1 input method ie Keyboard, xbox controller, mouse etc.
Create a Unity Scene with the same sprite and use a script to create similar movement.
Commit the mongame project and an export of the Unity Scene as a package to SVN or Moodle.
