把别人的Tcl/Tk代码加入到Go语言里15 游戏8 翻牌游戏
这次文章主要引用了网上的这篇教学http://www.cwflynt.com/TclForTeens/
步骤a 下载第17课里提到的扑克图像包
http://www.cwflynt.com/TclForTeens/cards.zip
解压缩cards.zip内所有文件到c:\cards\目录下
【你可以放在桌面的cards目录里,随意】
步骤b 跳到第20课http://www.cwflynt.com/TclForTeens/lsn20.html
找到最后一段框起来的源代码,它的上一句是“And that‘s all the changes. Here‘s the complete game.”
把这段框起来的代码复制到如下go代码的字符串常量里
package main import "github.com/nsf/gothic" const init_script = ` #init_script字符串常量,tcl/tk代码从下一行开始 ` func main() { ir := gothic.NewInterpreter(init_script) <-ir.Done }
步骤c 保存go文件到c:\cards\目录下
【总之和图像文件在一起、同一目录就行】
步骤d 运行和编译
liteide下编译如下图
运行效果如下图:
步骤e 发行
从ActiveTcl 开发环境的安装目录(一般都是c:\tcl\)下找到
bin文件夹,把里面的tcl86.dll tk86.dll和zlib1.dll这3个文件复制到
c:\cards\目录下
再从c:\tcl\lib下找到tcl8.6和tk8.6文件夹,把这俩也复制到
c:\cards\lib\下
【如果必要可以删除一些用不上的包以减少发布文件的大小】
【完】
【附上全部go源代码,只有400多行,其中含tcl/tk代码的#注释都快有100行了】
