按照官方教程所说需要mingw环境首先按照教程去下载 We tested the Windows build using the mingw-w64 toolchain (you can download this file in particular). 下载后将文件解压并添加环境变量(主要是bin、include、lib) 然后下载g3n源代码git clone https://github.com/g3n/engine g3n-engine同样添加下环境变量 重启然后可以开始install了cd g3n-engine
go install ./...测试
创建一个空文件加创建一个main.go 文件package mainimport (timegithub.com/g3n/engine/appgithub.com/g3n/engine/cameragithub.com/g3n/engine/coregithub.com/g3n/engine/geometrygithub.com/g3n/engine/glsgithub.com/g3n/engine/graphicgithub.com/g3n/engine/guigithub.com/g3n/engine/lightgithub.com/g3n/engine/materialgithub.com/g3n/engine/math32github.com/g3n/engine/renderergithub.com/g3n/engine/util/helpergithub.com/g3n/engine/window
