我是一名网络开发人员 (symfony <3 ;) C# 和 microsoft 技术对我来说是新的! )并且在covid遏制期间,我想用游戏引擎统一创建一个简单的游戏
在 Ubuntu 19.10 上,我下载了 unity Hub v2.3.0 ( https://unity3d.com/get-unity/download )
从统一集线器,我安装了 unity3D v2019.3.7f1 (最新稳定版)和一些选项( Linux & WebGL & windows build support )
我创建了一个简单的 2D 游戏
一切都像魅力一样,我可以在 unity3D 控制台中打开我的项目并运行我的新游戏而不会出现任何错误
在 Unity 中,当我创建一个 c# 脚本时,可以通过我的(非常简单的)文本编辑器 gedit 打开该文件。现在我想安装跨操作系统 IDE 可视化代码,谢谢,当我编辑统一脚本时,我会得到一些有用的扩展和自动完成代码。
所以,我通过 apt install
安装了 vscode(我遵循了这个官方指南:https://code.visualstudio.com/docs/setup/linux)
我的 vscode 版本是:
经过一些网络搜索,我知道我必须安装 .NET 框架(也许我错了?)
我的 dotnet 版本(来自终端:dotnet --version)是 3.1.201
接下来我配置了统一参数以更改默认文本编辑器:
