There are so many people capable of making games on Smile Basic. My question is: WHERE DO YOU LEARN ALL OF THIS?

There's a youtube series done by Petit Profesor. Copy the code and follow along. You'll learn how a lot of stuff works

has that helped you much?

If you want to learn SB, u need to go to the manual, petit professor 3d, and the online tutorials. This game is not for full beginners. u at least have to know basic knowledge.

the way i learned is by looking into other codes and trying it out myself

The videos will have tutorials like loading maps, moving sprites, and collision detection. They helped me (after watching a few times)

i do have an understanding of the basic fundamentals, i just need extra help. I also can't apply code from other program, if i can't figure it out

I finally don't understand where someone nowadays can learn BASIC. There is only the possibility to be a beginner
