Those links provided the information you need for making a basic feature of a simple rpg game.
You can explore the tutorial section, you can get all you need to create a rpg game.
For example, this additional links will help you start your RPG game:
Health Bar
Enemy AI for Top Down
Animation Management in 8 Direction Games
There's no full one-package RPG Tutorial. It will takes more than 20 pages of tutorial. I hope this helps
