A lot of the events DO have comments. Lemme walk ya through it. This'll go from the upper left hand corner to the right, then down a row, then to the right of that row, etc.
1) Comments, which attack is represented by which variable #
2) Which pokemon is which number
Next row
3) Manages the menu when it's your turn to attack
4) Manages what happens when you select Fight/PKMN/Item/Run
5) Manages the Attack navigation
Next Row
6) Depending on which attack, damage is calculated and animation is played
Next Row
7) Loads which attacks a given pkmn has (a lil' out of order)
Next Row
8) This has comments. It recalls CNS input (nicknames)
9) Shows each letter from the above step
10) Shows my beautiful pan and if it's a trainer battle, a trainer
11) Plays music
Next Row
12) Shows total pkmn you have and what the opponent trainer sends out among other things related to which pkmn you see
Two rows later...
13) Enemy level, PP, stats (attk, etc), KOing, etc. There are comments
Four rows later (at the bottom)
14) Items (like pk balls, etc)
I think I got that all right...
Sure, toothache. I'm glad you like RPG Maker. It's a powerful engine, and what's best is you don't have to hand-write the script!
And I don't have any credentials. No courses or anything in game dev or computer programming.
