# python-genshin-artifact 伤害计算
|
||
|
||
PaiGram 通过调用 python-genshin-artifact (下文简称 PGA) 模块实现角色伤害计算，该模块将 Rust 实现的 [genshin_artifact](https://github.com/wormtql/genshin_artifact) 库包装为 python 模块供 PaiGram 使用。
|
||
|
||
|
||
## 依赖
|
||
|
||
PGA 主要依赖 Rust 以及 PyO3 实现与 `genshin_artifact` 的对接：
|
||
|
||
- [Rust](https://www.rust-lang.org/)
|
||
- [PyO3](https://github.com/PyO3/pyo3)
|
||
- [Python 3.8+](https://www.python.org/)
|
||
|
||
## PYPI 安装
|
||
|
||
[python-genshin-artifact](https://pypi.org/project/python-genshin-artifact/)
|
||
|
||
```
|
||
pip install python-genshin-artifact
|
||
```
|
||
|
||
## 编译安装
|
||
|
||
1. 克隆项目
|
||
|
||
```
|
||
$ git clone https://github.com/PaiGramTeam/python-genshin-artifact.git
|
||
Cloning into 'python-genshin-artifact'...
|
||
...
|
||
```
|
||
|
||
2. 浏览至项目主目录下，用 `cargo` 编译 Rust 代码 (可选步骤)
|
||
|
||
```
|
||
$ cd python-genshin-artifact/
|
||
$ cargo build --no-default-features
|
||
...
|
||
Compiling python_genshin_artifact v1.0.0
|
||
Finished dev [unoptimized + debuginfo] target(s) in 25.67s
|
||
```
|
||
|
||
3. 编译成功后用 `pyo3/maturin` 安装至当前 Python 虚拟环境 (`env`)
|
||
|
||
```
|
||
(env) $ maturin develop
|
||
Compiling python_genshin_artifact v1.0.0
|
||
Finished dev [unoptimized + debuginfo] target(s) in 18.06s
|
||
📦 Built wheel for CPython 3.10 to /tmp/.tmpE21JWW/python_genshin_artifact-1.0.0-cp310-cp310-linux_x86_64.whl
|
||
🛠 Installed python_genshin_artifact-1.0.0
|
||
```
|
||
|
||
4. 至此，`python-genshin-artifact` 可被导入至项目中使用
|
||
|
||
```python
|
||
from python_genshin_artifact import get_damage_analysis, CalculatorConfig
|
||
|
||
calculator_config = CalculatorConfig(...)
|
||
damage_analysis = get_damage_analysis(calculator_config)
|
||
```
|
||
|
||
|
||
### 编译 wheel
|
||
|
||
如果需要导出给其它项目测试或使用 (例如 PaiGram)，需要通过 `maturin` 将模块编译成 `.whl` 格式以便其它 Python 虚拟环境安装。
|
||
|
||
1. `maturin build`：
|
||
|
||
```
|
||
$ maturin build --out dist
|
||
Finished dev [unoptimized + debuginfo] target(s) in 0.12s
|
||
📦 Built wheel for CPython 3.10 to dist/python_genshin_artifact-1.0.0-xxx.whl
|
||
```
|
||
|
||
2. 将上一步打包完成的 `.whl` 安装至另一个项目的虚拟环境中 (此处假定 PaiGram 用的虚拟环境名是 venv)
|
||
|
||
```
|
||
(venv) $ pip install dist/python_genshin_artifact-1.0.0-xxx.whl
|
||
```
|
||
|
||
3. 至此，PaiGram 项目就能导入 `python_genshin_artifact` 模块调用其中的函数了，具体用法参考 [PaiGram/plugins/genshin/player_cards.py](https://github.com/PaiGramTeam/PaiGram/blob/44a01bffd15bdb4b05e66fcd265d1e924490b4ef/plugins/genshin/player_cards.py#L620-L637)
