The clicker game, such as "Cookie Clicker" and "Tap Titan", there is no player character. With the interaction of UI, the game could be progress. However, the unity editor has a lot of uncomportance like auto-compiling. Previously, I have encounter many situations that the time has wasted. Today I determined to solve the question.
Auto compile
in Unity editorCompiling the scripts make a memory stack which will spend long time while compiling. The solution was simple, but I haven't understood the origin. In the Unity, there was built-in package, 'Burst'. However, that doesn't work well. For the operation, we have to re-install the package. For the experience of tutor, he has adopted that environment, not change the environment for him. But the tutor has over than 10 year career. Since he has accustomed the tool. For the beginner, the auto-compile will be annoying issue. As a conclusion, the adoption is on the user choice.
