Talon Engine

Talon Engine is a lightweight, modular 2D game engine written in C++ using SDL2.
Inspired by Unity, designed from scratch, and built with pure muscle.

---

Features

• GameObject + Component System
  Inspired by Unity, every object is modular, dynamic, and follows a clean lifecycle: Awake(), Start(), Update().

• Input System
  Handles real-time keyboard input (WASD, spacebar, Shift) using SDL2's raw scancodes.

• Animator with Frame Events
  Spritesheet-based animation with timing control, direction switching, and frame-triggered callbacks (std::function per frame).

• SpriteRenderer
  Renders sprites with SetSourceRect() support for pixel-perfect control over frames and spritesheets.

• Rigidbody2D Physics

  • Gravity, drag, velocity, acceleration
  • AddForce() and ApplyImpulse()
  • Fully frame-based physics update with jump support

• BoxCollider
  Collision detection with offset support, overlap handling.

• CollisionManager
  Handles collision resolution and prediction before applying movement.

• Vector2 Math Library
  Clean utility methods like Normalize(), Length(), Dot(), and operator overloads.

• Folder-based project layout
  Organized includes, systems, and components — Visual Studio–friendly.

• Built From Scratch
  No engine templates, no frameworks — just pure C++ and SDL2.

In Progress / Planned

• JSON-based prefab & scene loading
• Tilemap & Z-Ordering
• CircleCollider
• In-engine level editor (drag, drop, save)
• Audio system (sound FX, music)
• Save/load game state
• Component editor UI
• Particle system & animation blending

Requirements

• SDL2
• vcpkg
• C++17 or higher
• Visual Studio (recommended)

🔧 Getting Started

Follow these steps to build and run Talon Engine locally.

1. Clone the Repository

git clone https://github.com/severmanolescu/Talon.git

2. Install Dependencies with vcpkg

If you don’t have vcpkg installed yet:

git clone https://github.com/microsoft/vcpkg.git
cd vcpkg
./bootstrap-vcpkg.bat

Then install SDL2 and SDL2-Image:

vcpkg install sdl2 sdl2-image 

3. Open the Project in Visual Studio

• Open Talon.sln

• Go to Project Properties > VC++ Directories

• Add:

  • Include Directories: C:\path\to\vcpkg\installed\x64-windows\include

  • Library Directories: C:\path\to\vcpkg\installed\x64-windows\lib

4. Link SDL2 Libraries

Go to Project Properties > Linker > Input > Additional Dependencies, and add:

SDL2.lib SDL2main.lib SDL2_image.lib

Copy all the dlls from C:\path\to\vcpkg\installed\x64-windows\bin next to the .exe at runtime
