How to use

Update Input

If you use HxInput without HxSystem then you have to call this code to update the input device states

Input.Instance.Update(gameTime);

If you use HxInput with HxSystem then you have to call this code to update the input device states

Hx.Instance.Update(gameTime);

Mouse Input

public Vector2 MouseDistanceVectorFrom(Vector2 position);
public Vector2 MouseDistanceVectorFrom(Point position);
public Point MouseDistancePointFrom(Vector2 position);
public Point MouseDistancePointFrom(Point position);
public bool IsMouseKeyDownOnce(MouseButton button);
public bool IsMouseKeyDown(MouseButton button);
public bool IsMouseKeyUpOnce(MouseButton button);
public bool IsMouseKeyUp(MouseButton button);

Keyboard Input

public bool IsKeyboardKeyDownOnce(Keys key);
public bool IsKeyboardKeyDown(Keys key);
public bool WasKeyboardKeyDown(Keys key);
public bool IsKeyboardKeyUpOnce(Keys key);
public bool IsKeyboardKeyUp(Keys key);
public bool WasKeyboardKeyUp(Keys key);
public void TextEntered(object sender, TextInputEventArgs e);

Example

How to process text input with keyboard

Game1 Class

public class Game1
{
/*
 * Your Code
**/
Window.TextInput += InputManager.Instance.TextEntered; //Registers Methode To TextInput Event
}

TextInput Class - used in HxUserInterface (not released yet)

public string Text = "Text"; //Content Of The TextInput
public SpriteFont Font;

public bool Focus = false; //If The TextInput Has Focus
public bool Edit = false; //If The TextInput Can Be Edited

public TextInput()
{
    Input.Instance.OnCharDown += OnInput;
}

public void Update(GameTime gameTime);
public void Draw(SpriteBatch spriteBatch, GameTime gameTime);

private void OnInput(object sender, KeyboardCharEventArgs e)
{
    if (!Focus)
    {
        return;
    }
    switch (e.Char)
    {
        case '\a':
            break;
        case '\f':
            break;
        case '\r':
            break;
        case '\n':
            break;
        case '\t':
            break;
        case '\v':
            break;
        case '\0':
            break;
        case '\x1B':
            break;
        case ' ':
            Text = Text?.Insert(Text.Length, " ");
            break;
        case '\b':
        {
            if (Text.Length - 1 >= 0)
            {
                Text = Text?.Remove(Text.Length - 1);
            }
            break;
        }
        default:
            if (Font.Characters.Contains(e.Char))
            {
                Text = Text?.Insert(Text.Length, e.Char.ToString());
            }
            break;
    }
}

This code prints "Key Pressed" only one time when the key "G" was pressed

Using OnKeyDown Event

public void foo(object sender, KeyboardKeyEventArgs args)
{
    if (args.Key == Keys.G)
    {
        Console.WriteLine("Key Pressed");
    }
}

//Somewhere in the code
Input.Instance.OnKeyDown += foo;

Using IsKeyboardeKeyDownOnce Method

if (Input.Instance.IsKeyboardeKeyDownOnce(Keys.G))
{
  Console.WriteLine("Key Pressed");
}

GamePad Input

public bool IsGamepadButtonDown(PlayerIndex index, Buttons button);
public bool IsGamepadButtonUp(PlayerIndex index, Buttons button);
public bool WasGamepadButtonDown(PlayerIndex index, Buttons button);
public bool WasButtonUp(PlayerIndex index, Buttons button);
public bool IsGamepadButtonPressed(PlayerIndex index, Buttons button);
public bool IsButtonReleased(PlayerIndex index, Buttons button);
public bool IsGamePadConnected(PlayerIndex index);
public bool WasGamePadConnected(PlayerIndex index);
public bool IsGamePadDisconnected(PlayerIndex index);
public bool WasGamePadDisconnected(PlayerIndex index);

Touch Input
