Engine Demo

A demo application using my game engine. It consists of a multi-layer tilemap and a player sprite (also form the tilemap). The player can move using WSAD, arrows or pressing edges of the screen on Android devices. Player position is linearly interpolated to provide smooth camera movement. The position is rounded to the nearest pixel when still.

Supported platforms

• Android
• Linux
• Windows
• MacOS

Requirements

• GPU compatible with one of the following:
  • OpenGL 3.0+
  • OpenGL 2.1 with GL_EXT_framebuffer_object extension
  • OpenGL ES 2.0

Building

Android

Open android folder in Android Studio (Panda or newer, with NDK installed), connect a supported Android device with USB Debugging enabled and click Run or Debug. The required libraries will be automatically downloaded.

Linux

Prerequisites:

• GCC 13+ or Clang 17+
• glibc 2.37
• CMake 3.6+

The easiest way to build on any GNU/Linux distribution is to download and compile dependencies automatically alongside the engine:

cmake -DENGINE_USE_SYSTEM_LUA_LIB=OFF -DENGINE_USE_SYSTEM_GLM_LIB=OFF -DENGINE_USE_SYSTEM_FREETYPE_LIB=OFF -DENGINE_USE_SYSTEM_NLOHMANN_JSON_LIB=OFF -DENGINE_USE_SYSTEM_GLFW_LIB=OFF -DCMAKE_POLICY_VERSION_MINIMUM=3.5 -DCMAKE_BUILD_TYPE=Release -B build -S .
cd build
make -j16

Alternatively, install required libraries (Lua, glm, freetype, nlohmannjson and GLFW) with a package manager and run

cmake -DCMAKE_BUILD_TYPE=Release -B build -S .
cd build
make -j16

Then run the demo (the program binary is located in the parent folder):

cd ..
./EngineDemo

Windows

Prerequisites:

• MSVC 2019 version 16.10 or newer with Build Tools
• CMake 3.6+

Open Microsoft x64 Native Tools Command Prompt. Enter the project directory. Type:

cmake -DCMAKE_POLICY_VERSION_MINIMUM=3.5 -DCMAKE_BUILD_TYPE=Release -G "NMake Makefiles" -B build -S .
cd build
nmake

Then run EngineDemo.exe in the parent folder

MacOS

Prerequisites:

• Apple Clang 17+
• CMake 3.6+

Open CMake GUI. Select the project folder and create a build folder. Add variable CMAKE_POLICY_VERSION_MINIMUM and set it to 3.5. Then click Configure and Generate. The required libraries will be automatically downloaded. Enter the build folder in a terminal and type:

make

Then enter the root repo folder and launch the demo:

./EngineDemo

Assets

The assets used in the app are from CRAFTPIX free tilesets.
