forestrf / UnityScriptReloadFixer.cs

Last active July 26, 2018 19:10

[FIXED BY UNITY. This is not needed at all anymore] Unity sometimes does not reload my scripts when reimporting them. Apparently the .dlls inside /Library/ScriptAssemblies are not always replaced by the generated dlls inside /Temp, so this scripts moves those dlls automatically

	using System;
	using System.IO;

	class Program {
	static void Main(string[] args) {
	Console.WriteLine("Close this window when you are finished doing cool progress");
	Console.WriteLine("first argument: path to Library folder");

	// Path
	string path = new FileInfo(System.Reflection.Assembly.GetEntryAssembly().Location).Directory.FullName;
