tutorials   Welcome to JS Build If it wasn't for Build, I may have never gained an interest in mapping levels, at all. It is one of the easiest level editors around and a great editor for learning how to build your own maps. You will certainly learn all the essentials of level making and everything you do in Build to make a level come to life you will carry with you on to other level editors. This site has been around for going on five years and I never thought that it would have helped so many Builders. Enjoy and happy Building! Please check the site map. You'll find all the tutorials and editing links you'll need.
