I want to build my game in web, but there are not webplayer in build page, and download page. And I already download webplayer file in unity website, but It was plugin. How can I build my game in version 5.4.2? Help me…
WebPlayer builds were deprecated and removed from Unity due to policies that affected the plugin nature of the WebPlayer(read as the obsoleted and removed the old netscape plugin implementation from chrome and all that). WebPlayer builds are to be replaced by WebGL platform builds, there isn’t any reason to use WebPlayer since browsers are removing the code that supports the plugin in general and it’s dead.
As Landern has said the WebPlayer build target was removed in Unity 5.4. For web builds you should now use WebGL.
