Nevo Engine

Overview

The InputManager provides a unified interface for polling keyboard and mouse state. You can access it via the global Engine instance.

auto& engine = Public::Engine::getInstance();
Public::Input::InputManager& inputManager = engine.GetInputManager();

Keyboard Input

Checking Key States

IsKeyDown(keyCode): Returns true if the key is currently held down.
GetKeyDown(keyCode): Returns true only on the frame the key was pressed.

using namespace Public::Input;

if (inputManager.IsKeyDown(Key::Code::W)) {
    // Move forward
}

if (inputManager.GetKeyDown(Key::Code::Space)) {
    // Jump (trigger once)
}

Mouse Input

Mouse State

You can retrieve the current mouse position and delta (movement since last frame).

MouseState mouse = inputManager.GetMouseState();
float yaw = mouse.deltaX * sensitivity;
float pitch = mouse.deltaY * sensitivity;

Cursor Control

The InputManager allows you to lock and hide the cursor, which is essential for first-person camera controls.

inputManager.LockCursor(); // Locks to center and hides
inputManager.UnlockCursor(); // Restores normal behavior
