Pong OpenTK Game

A simple 2D Pong game implemented in C# using OpenTK for OpenGL rendering. Features two-player controls (W/S for Player 1, Up/Down for Player 2), scoring to 5 points, and text rendering for UI.

Requirements

• .NET 6.0 or later (tested on .NET 8.0).
• OpenTK 4.x (via NuGet).
• System.Drawing.Common (via NuGet; Windows-only for full text rendering; on non-Windows, install libgdiplus via package manager, e.g., sudo apt install libgdiplus on Ubuntu).
• Visual Studio 2022 or VS Code with C# extension (for development).

Libraries

• OpenTK: Cross-platform OpenGL bindings, windowing, and input. Installed via <PackageReference Include="OpenTK" Version="4.8.2" />.
• System.Drawing.Common: For text bitmap generation. Installed via <PackageReference Include="System.Drawing.Common" Version="8.0.0" />. Note: On non-Windows, runtime may throw PlatformNotSupportedException unless libgdiplus is installed.

Building for Release

dotnet publish -c Release -r win-x64 --self-contained

Adjust runtime identifier (RID) for your platform (e.g., linux-x64).

Known Issues

• Text rendering limited on non-Windows without libgdiplus.
• Uses OpenGL 3.3 core profile; ensure compatible GPU.
