虚幻4编译手记

虚幻4的源文件组织码相对与虚幻3个人感觉清楚了很多,明显是良心准备过的。编译非常简单,基本都是自动化一键生成的,去git下两个依赖文件(有个可选项,我没下),解压与源代码文件融合,运行根目录下的GenerateProjectFiles.bat文件1分钟以内就生成了一个sln解决方案文件,打开选择development Editor,直接build UE4即可,不需要其他的任何设置。编译时间会持续15到40分钟。编译完成后,直接调试就可以打开编辑器。

可选项:GenerateProjectFiles.bat默认会生成所有检测到SDK的平台的构建项目,使用-CurrentPlatform来仅生成当前平台的构建项目。
重要的一点:每次更新源代码后都要运行GenerateProjectFiles.bat,否则可能会无法编译。如果自己改动了模块(比如增删源文件),也要重新运行GenerateProjectFiles.bat。官方不推荐手动更改项目文件。也可以使用UnrealVS来重新生成项目当前加载项目的项目文件。
如果只是想使用学习UE4的话,推荐还是使用官方编译好的编辑器,以防止出现一些无解的问题。

记录几个我在windows上构建时遇到的几个小细节。

1、依赖包的正确融合

2、保持磁盘空间在15G以上

3、生成完成后如果在编译DefaultDeferredDecalMaterial时候自动退出,注销系统再启动即可。(具体原因不是很清楚,可能是因为某些程序被长期占用的缘故。)

但是需要注意的是:

使用Development Editor编译出来的编辑器在我的电脑上经常出现打包问题,因该是从来没有打包成功过,而且打包过程相当缓慢。最后打包失败似乎还是因为编译DefaultDeferredDecalMaterial失败。

没有仔细读过官方文档,具体问题原因还不知道,希望知道答案的人赐教。

log如下:
