i'm looking for full tutorial but nothing ! please dear boxers do you already have background in game Dev such as unity before you became a boxer ?
The best course of action for mastering Buildbox fast is by following the "Make Your Own Game" Series. Do all the parts of the tutorial and you'll be awesome with it in no time. https://www.buildbox.com/make-your-own-game/
I started making games with Buildbox about one year ago; I had 0 experience in design or game development. Take some time to learn Buildbox by yourself and make lots of games. Of course, the BB Youtube channel is useful, but the most you'll learn while you experiment by yourself. Cheers
