Input

The Input is managed by the Window system, using GLFW to retrieve the system events. These events are then passed onto the Input system, which in turn manages the state of Pressed, Released, and their variants in JustPressed and JustReleased.

Functions

Using the Enums below, you can access their state by calling one of these functions:

For Key, MouseButton, Pad:

• IsPressed() Checks if the state of the Key/Button is Pressed.
• IsJustPressed() Checks if the state of the Key/Button has changed to Pressed. Please note that this function must be called every frame for the State to properly flush.
• IsJustReleased() Checks if the state of the Key/Button has changed to Released. Please note that this function must be called every frame for the State to properly flush.

For JoyStick:

• GetAxis() Returns a float with the Axis of the given JoyStick.

Example

void UpdateInput() {
  float speed = 2.5f * Time.deltaTime;
  if (Key.W.IsPressed())
    this.position -= front * speed;
  if (Key.S.IsPressed())
    this.position += front * speed;
  if (Key.A.IsPressed())
    this.position += front.Cross(up).Normalize() * speed;
  if (Key.D.IsPressed())
    this.position -= front.Cross(up).Normalize() * speed;
  if (Key.E.IsPressed())
    this.position += up * speed;
  if (Key.Q.IsPressed())
    this.position -= up * speed;
}

Warning

A possible mistake while using the Just variants is that they are not called in every frame. This is wrong:

void Update() {
  if (Key.LeftControl.IsPressed() && Key.Q.IsJustPressed()) {
    // Something
  }
}

Since the second statement is not called on every frame, the state is not flushed properly, causing it to be always true whenever the Key Q has been pressed in the past, but not necessarily in that moment.
