TrainEngine

Cross-platform 2D game engine made with C++ and SFML.

Features

• Game state management
• Multimedia resource manager
• Input manager (with both callbacks and polling support)
• Frame interpolation
• Multi-view camera
• Animated entities
• Parallax
• GUI
• Tilemap level editor
• Physics
• Profiling information

Prerequisites

Toolchain

• GCC or Clang

  Note: For Windows, make sure you have MinGW-w64 SEH 6.1.0 64-bit installed and in your PATH. This version is important since SFML's binaries are shipped with the engine. If you want to use a different compiler, you must recompile SFML 2.4.2 and replace it in the engine under libs/SFML-2.4.2.

• Make

  Note: For Windows, you should use Git Bash (shipped with Git for Windows). Use mingw32-make instead of make.

• clang-format
• clang-tidy
• Doxygen and Graphviz

Dependencies

• SFML 2.4.2 or 2.5.1
  • Linux: Install SFML using your system's package manager. For example: sudo apt install libsfml-dev
  • macOS: Install SFML using the instructions here.
  • Windows: Windows will use the vendored SFML library under libs/SFML-2.4.2.
