0450dc3547 Adds concept for prediction engine traits
Introduces a concept `PredEngineConcept` to ensure that classes used as projectile prediction engine traits conform to a specific interface.
This enforces the presence and return types of required methods and ensures that these methods are `noexcept`, improving type safety and predictability.
2025-08-12 09:21:34 +03:00
0bd9eda48f Introduces CameraEngine concept
Adds a concept `CameraEngineConcept` to ensure that camera
engine implementations provide the necessary functions
with the correct signatures and `noexcept` specifications.

This enables compile-time checks for valid camera engine
implementations, improving code reliability and preventing
runtime errors.

Refactors camera and prediction using traits
2025-08-11 00:47:25 +03:00
17b150499d Refactors camera and prediction engine traits.
Moves camera and prediction engine implementations into traits for each engine,
decoupling the engine-specific logic from the core classes, promoting code reuse
and maintainability. This change allows for easier addition of new engines and
customization of existing ones.

2025-08-06 06:23:06 +03:00
08d2ccc03a Refactors Vector operations for type safety
Ensures type safety in Vector2, Vector3, and Vector4 operations by using static_cast(0) instead of relying on implicit conversions.
This prevents potential issues with different numeric types.

Adds from_im_vec2 and from_im_vec4 methods for creating vectors from ImVec2/ImVec4 types.

2c4ff37062 Merge pull request #52 from orange-cpp/feature/more_traits
Adds engine traits for projectile prediction
2025-08-06 05:49:25 +03:00
695a8035b5 Adds engine traits for projectile prediction
Implements engine-specific traits for projectile and target position prediction.
Each trait encapsulates logic tailored to a specific game engine (IW, OpenGL, Unity),
accounting for engine-specific coordinate systems and calculations.
This allows for accurate projectile prediction across different game environments.
2025-08-06 05:45:37 +03:00
d12b236e56 Refactors target position prediction
Moves target prediction logic into engine traits, improving modularity.

This change consolidates target position prediction within the engine traits,
allowing for a more flexible and maintainable design.

This eliminates redundant code and simplifies the core prediction engine by
delegating target movement calculations to the appropriate trait.

f1fbea21a7 Refactors projectile prediction engine
Refactors the projectile prediction engine by introducing an interface
and making the legacy implementation more flexible.

The legacy engine is updated to allow for coordinate system customization
through virtual methods, enabling usage in different game environments.

Also introduces vcpkg support for easier dependency management and adds boost-asio as a dependency.

1aa62cb396 Enables legacy code compilation
The changes encapsulate the matrix tests within an `#ifdef` block, allowing conditional compilation based on whether `OMATH_ENABLE_LEGACY` is defined. This enables the legacy code to be compiled only when needed.
2025-07-15 11:51:14 +03:00
8e411771c2 Adds option to enable legacy classes
Introduces a CMake option to enable legacy classes,
allowing for backward compatibility with older code.

# Generated from CLion C/C++ Code Style settings

Language: Cpp
# Generated by CLion for Stroustrup
# The Stroustrup style, named after Bjarne Stroustrup, the creator of C++, is similar to the K&R style but differs
# in its treatment of the class definitions and the placement of braces in certain contexts. The opening brace is
# placed on the same line as the control statement, and the closing brace is on its own line.

## 🤝 Contributing to OMath or other Orange's Projects
### ❕ Prerequisites
- A working up-to-date OMath installation
- C++ knowledge
- Git knowledge
- Ability to ask for help (Feel free to create empty pull-request or PM a maintainer
in [Telegram](https://t.me/orange_cpp))
### ⏬ Setting up OMath
Please read INSTALL.md file in repository
### 🔀 Pull requests and Branches
In order to send code back to the official OMath repository, you must first create a copy of OMath on your github
account ([fork](https://help.github.com/articles/creating-a-pull-request-from-a-fork/)) and
then [create a pull request](https://help.github.com/articles/creating-a-pull-request-from-a-fork/) back to OMath.
OMath developement is performed on multiple branches. Changes are then pull requested into master. By default, changes
merged into master will not roll out to stable build users unless the `stable` tag is updated.
### 📜 Code-Style
The orange code-style can be found in `.clang-format`.
### 📦 Building
OMath has already created the `cmake-build` and `out` directories where cmake/bin files are located. By default, you
can build OMath by running `cmake --build cmake-build/build/windows-release --target omath -j 6` in the source
directory.
