F-XX (Airborne)

An indie flight simulator gmae without any game engine, just C++ and some libraries.

This project trys to make a little bit modern remake of the classic F-15 Strike Eagle II and others flight simulators made by MicroProse back in the 80s.

The magic of those games comes from the fact it is not really a simulator, and it is not really an arcade. It somthing between just genius like Sid Meier can create :).

Check out the development blog for updates ot the Wiki for more information.

How to

Still in progress, but...

cmake --build cmake-build-debug
./cmake-build-debug/se

The Rules

• Do not use game engine and or LLM
• I have to re-learn CPP and linear algebra (ohh, trigonometry)
• To have fun

Nostalgia Moment

I spent so many hours flying this beast on my XT-16MGhz machine with monochrome CGA resolution screen. I tried to play it again, it was fun but somthing is missing. No, I don't want another DCS neither an arcade game, I want the same gameplay I got from this magic game, so this project has begun.

TODOs

Leftovers from the ESC refactoring:

• fog shader
• complete configuring the terrain streamer
• performance optimizations: change read only view data to const reference
• autopilot controller
• navball widget

Modules Rules

module;
// includes only here:
#include <vector>

export module MyModule;

// import only here:
import JsonConfig;

export class MyClass { ... };

Modern CPP Rules

• Modules
• static_cast for casting
• if-init statements
• auto for type inference
• constexpr for compile-time constants
• nullptr instead of NULL

Style Rules

• Use PascalCase for class names, structs, and enums
• Use snake_case for variables, methods, and functions

Build

The project require C++ compiler with support for C++20 modules, and CMake 3.25 or higher.

I'm using LLVM. My configuration looks like this (macos):

export CC=$(brew --prefix llvm)/bin/clang
export CXX=$(brew --prefix llvm)/bin/clang++

cmake -B cmake-build-debug -S . -DCMAKE_BUILD_TYPE=Debug -G Ninja
cmake -B cmake-build-release -S . -DCMAKE_BUILD_TYPE=Release -G Ninja
cmake -S . -B cmake-build-asan -G Ninja -DCMAKE_BUILD_TYPE=Debug -DCMAKE_CXX_FLAGS="-fsanitize=address -g -fno-omit-frame-pointer" -DCMAKE_EXE_LINKER_FLAGS="-fsanitize=address"

# clean builds
cmake --build cmake-build-debug --target clean && cmake --build cmake-build-debug
