Hey onlyfeng! We would like to see what you might need in terms for help in the help tab,
there we can help you any question you might wanna ask about unity!
Please do not be afraid to ask simple questions, we will answer no matter how simple
The physics engine is a piece of cake, it doesn't take much to get started.
Rendering is medium'ish, as long as you can write good shaders and scripts to render the shaers,
you get a pretty looking game
I hope you enjoy the forum!
