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.

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.

## 🤝 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.

# Code Of Conduct
## 🎯 Goal
My goal is to provide a space where it is safe for everyone to contribute to,
and get support for, open-source software in a respectful and cooperative
manner.
I value all contributions and want to make this project and its
surrounding community a place for everyone.
As members, contributors, and everyone else who may participate in the
development, I strive to keep the entire experience civil.
## 📜 Standards
Our community standards exist in order to make sure everyone feels comfortable
contributing to the project(s) together.
Our standards are:
- Do not harass, attack, or in any other way discriminate against anyone, including
for their protected traits, including, but not limited to, sex, religion, race,
appearance, gender, identity, nationality, sexuality, etc.
- Do not go off-topic, do not post spam.
- Treat everyone with respect.
Examples of breaking each rule respectively include:
- Harassment, bullying or inappropriate jokes about another person.
- Posting distasteful imagery, trolling, or posting things unrelated to the topic at hand.
- Treating someone as worse because of their lack of understanding of an issue.
## ⚡ Enforcement
Enforcement of this CoC is done by Orange++ and/or other core contributors.
I, as the core developer, will strive my best to keep this community civil and
following the standards outlined above.
### 🚩 Reporting incidents
If you believe an incident of breaking these standards has occurred, but nobody has
taken appropriate action, you can privately contact the people responsible for dealing
with such incidents in multiple ways:
***E-Mail***
- `orange-cpp@yandex.ru`
***Discord***
- `@orange_cpp`
***Telegram***
- `@orange_cpp`
I guarantee your privacy and will not share those reports with anyone.
## ⚖️ Enforcement Strategy
Depending on the severity of the infraction, any action from the list below may be applied.
Please keep in mind cases are reviewed on a per-case basis and members are the ultimate
deciding factor in the type of punishment.
If the matter benefited from an outside opinion, a member might reach for more opinions
from people unrelated, however, the final decision regarding the action
to be taken is still up to the member.
For example, if the matter at hand regards a representative of a marginalized group or minority,
the member might ask for a first-hand opinion from another representative of such group.
### ✏️ Correction/Edit
If your message is found to be misleading or poorly worded, a member might
edit your message.
### ⚠️ Warning/Deletion
If your message is found inappropriate, a member might give you a public or private warning,
and/or delete your message.
### 🔇 Mute
If your message is disruptive, or you have been repeatedly violating the standards,
a member might mute (or temporarily ban) you.
### ⛔ Ban
If your message is hateful, very disruptive, or other, less serious infractions are repeated
ignoring previous punishments, a member might ban you permanently.
## 🔎 Scope
This CoC shall apply to all projects ran under the Orange++ lead and all _official_ communities
outside of GitHub.
However, it is worth noting that official communities outside of GitHub might have their own,
additional sets of rules.

# 📥Installation Guide
## Using vcpkg
**Note**: Support vcpkg for package management
1. Install [vcpkg](https://github.com/microsoft/vcpkg)
2. Run the following command to install the orange-math package:
```
vcpkg install orange-math
```
CMakeLists.txt
```cmake
find_package(omath CONFIG REQUIRED)
target_link_libraries(main PRIVATE omath::omath)
```
For detailed commands on installing different versions and more information, please refer to Microsoft's [official instructions](https://learn.microsoft.com/en-us/vcpkg/get_started/overview).
## Build from source using CMake
1. **Preparation**

Oranges's Math Library (omath) is a comprehensive, open-source library aimed at providing efficient, reliable, and versatile mathematical functions and algorithms. Developed primarily in C++, this library is designed to cater to a wide range of mathematical operations essential in scientific computing, engineering, and academic research.
## 👁‍🗨 Features
- **Efficiency**: Optimized for performance, ensuring quick computations using AVX2.
- **Versatility**: Includes a wide array of mathematical functions and algorithms.
- **Ease of Use**: Simplified interface for convenient integration into various projects.
- **Projectile Prediction**: Projectile prediction engine with O(N) algo complexity, that can power you projectile aim-bot.
- **3D Projection**: No need to find view-projection matrix anymore you can make your own projection pipeline.
- **Collision Detection**: Production ready code to handle collision detection by using simple interfaces.
- **No Additional Dependencies**: No additional dependencies need to use OMath except unit test execution
- **Ready for meta-programming**: Omath use templates for common types like Vectors, Matrixes etc, to handle all types!
