Meanwhile, Unity is working on developing its own UnityScript to C# conversion tool to help developers through the transition.
For now, this means that Unity is no longer accepting Asset Store submissions that contain UnityScript code.
Unity has begun the process of sunsetting its C# alternative UnityScript, partially in an effort to free up resources for a number of other projects within the company.
All in all, 3.6 percent of all projects owe at least 20 percent of their code to UnityScript, while .8 percent use the language exclusively.
