TAPython_Taichi_StableFluid_UE5

This is a UE5 demo project for demonstrating how to modify volumetric clouds with only python though TAPython plugin and taichi-lang. This project has already contain the lastest TAPython v1.0.7.

Prerequisites

• Unreal Engine version 5.0.3
• Launch project, open Project settings - Plugin Python - additional path, add TAPythonTaichiClouds/TA/TAPython/Python to additional path. then restart the editor.
• install taichi-lang in Unreal Engine, and make sure 'import taichi as ti' works fine in UE's python console

My recommendation for using 3rd python package in UE：

1. Install Python 3.9.7 which is same version of UE5's python
2. Create a virtual environment for UE5
3. Install the 3rd package in the virtual environment
4. Add the /lib/site-packages directory which under the virtual environment to ProjectSetting/ plugins-python /Additional Paths in Unreal Editor. Relaunch the editor.

step

• Open the project and the level: /Content/StableFluid_Cloud.umap
• Click the Chameleon icon on the toolbar, Menuitem / Taichi/Taichi Stable Fluid
• Click and drag on the 'black window'
• Have fun

Core python script：

• TAPythonTaichiClouds\TA\TAPython\Python\TaichiStableFluid.py

TAPython_Taichi_StableFluid_UE5

在UE5中通过TAPython和Taichi-lang修改体积云覆盖范围的工程。本工程已包含预编译的TAPython插件v1.0.7

本示例仅供演示TAPython与Taichi-lang在UE5中的通讯之用，非游戏实际实现步骤。

先决条件

• Unreal Engine 版本5.0.3
• 在ProjectSetting/ Plugins-Python/Additional Paths中将当前UE工程中的TA/TAPython/Python 目录加入其中
• unreal的python中安装taichi-lang，确保在unreal的 python console中可以正确导入

UE5中使用其他三方库的推荐做法：

1. 本地安装Python 3.9.7（UE5 使用的Python版本为3.9.7）
2. 创建UE5使用的Python虚拟环境
3. 在虚拟环境中，安装taichi等三方package
4. 在UE5中，将虚拟环境所在目录下的/Lib/site-packages 目录添加到 ProjectSetting/ Plugins-Python/Additional Paths中。重启编辑器

演示步骤

• 打开工程，关卡地图为 /Content/StableFluid_Cloud.umap
• 点击 工具栏绿色变色龙图标（Python Chameleon Tools）/ Taichi/Taichi Stable Fluid
• 在黑色窗口点击鼠标绘制
• Have fun
