I wanted to know is there a fast and easy way to get used to the engine,and making a efficient project without knowing little about code?

Being fairly new to this myself, congratulations on opening communication with a forum. Asking for help always saves time. There are some YouTube tutorials I've found helpful, DevAddict is the channel for the video I'm currently watching. He gives you a basic idea of what to grasp starting out. From there I leave you to the more experienced people on this site, and look forward to learning from them as well. Thanks for asking.
