Keyboard Input

Handle keyboard input using the RaylibInput static class.

using Xengine.Rendering;

Methods

IsKeyDown

static bool IsKeyDown(KeyCode key)

Returns true while the key is held down.

if (RaylibInput.IsKeyDown(KeyCode.W))
    Transform.Position += Vector3.Forward * speed * Time.Delta;

IsKeyPressed

static bool IsKeyPressed(KeyCode key)

Returns true only on the frame the key was pressed.

if (RaylibInput.IsKeyPressed(KeyCode.Space))
    Jump();

IsKeyReleased

static bool IsKeyReleased(KeyCode key)

Returns true only on the frame the key was released.

if (RaylibInput.IsKeyReleased(KeyCode.LeftShift))
    EndSprint();

IsAnyKeyPressed

static bool IsAnyKeyPressed()

Returns true if any key was pressed this frame.

Common Patterns

WASD Movement

protected override void OnUpdate()
{
    var move = Vector3.Zero;
    
    if (RaylibInput.IsKeyDown(KeyCode.W)) move.Z += 1;
    if (RaylibInput.IsKeyDown(KeyCode.S)) move.Z -= 1;
    if (RaylibInput.IsKeyDown(KeyCode.A)) move.X -= 1;
    if (RaylibInput.IsKeyDown(KeyCode.D)) move.X += 1;
    
    if (move.LengthSquared > 0)
    {
        move = move.Normalized * Speed * Time.Delta;
        Transform.Position += move;
    }
}

Jump with Cooldown

private bool _canJump = true;

protected override void OnUpdate()
{
    if (RaylibInput.IsKeyPressed(KeyCode.Space) && _canJump)
    {
        _velocityY = JumpForce;
        _canJump = false;
    }
    
    // Reset when grounded
    if (_isGrounded)
        _canJump = true;
}

Sprint with Shift

protected override void OnUpdate()
{
    float speed = BaseSpeed;
    if (RaylibInput.IsKeyDown(KeyCode.LeftShift))
        speed = SprintSpeed;
    
    // Apply movement...
}

Menu Navigation

if (RaylibInput.IsKeyPressed(KeyCode.Escape))
    TogglePauseMenu();

if (RaylibInput.IsKeyPressed(KeyCode.Up))
    SelectPreviousOption();
    
if (RaylibInput.IsKeyPressed(KeyCode.Down))
    SelectNextOption();
    
if (RaylibInput.IsKeyPressed(KeyCode.Enter))
    ConfirmSelection();
