The Input class is a static helper for checking the state of the keyboard and mouse.

Methods

Method	Description
bool IsKeyPressed(int)	Check if a key is currently held down.
bool IsKeyJustPressed(int)	Check if a key was pressed during this frame.
bool IsMouseButtonPressed(int)	Check if a mouse button is currently held down.
void SetCursorMode(int)	Set the cursor mode (0: Normal, 1: Captured/Hidden).
int GetCursorMode()	Get the current cursor mode.

Properties

Property	Type	Description
MousePosition	Vector2	Current mouse screen coordinates.
MouseDelta	Vector2	Mouse movement since the last frame.
ScrollDelta	float	Scroll wheel movement since the last frame.

Usage

public override void OnUpdate(float delta) {
    if (Input.IsKeyJustPressed(71)) { // 'G'
        Log.Info("G was pressed this frame!");
    }

    if (Input.IsMouseButtonPressed(0)) { // Left click
        var mousePos = Input.MousePosition;
        Log.Info($"Mouse clicked at: {mousePos.X}, {mousePos.Y}");
    }
}

Note on Keycodes

Helios uses standard GLFW keycodes. For common keys, the keycode typically matches the ASCII value for the uppercase character (e.g., 'A' is 65, 'S' is 83).
