This is a companion series to Slip into Ruby (my teardown of the RPG Maker VX Ace default scripts) and aims to teach a bit of Javascript while explaining exactly how everything works under the hood of MV's .js files.

Part 1: https://rpgmaker.net/tutorials/1230/ (main.js, rpg_scenes.js (Scene_Base))
Part 2: https://rpgmaker.net/tutorials/1357/ (rpg_scenes.js (Scene_Boot, Scene_Title))
Part 3: https://rpgmaker.net/tutorials/1358/ (rpg_scenes.js (Scene_Map))
Part 4: https://rpgmaker.net/articles/1359/ (rpg_scenes.js (Scene_MenuBase, Scene_Menu, Scene_ItemBase, Scene_Item, Scene_Skill))
Part 5: https://rpgmaker.net/articles/1362/ (rpg_scenes.js (Scene_Equip, Scene_Options, Scene_File, Scene_Save, Scene_Load, Scene_GameEnd, Scene_Shop))
Part 6: https://rpgmaker.net/articles/1378/ (rpg_scenes.js (Scene_Name, Scene_Debug, Scene_Battle))
Part 7: https://rpgmaker.net/articles/1384/ (rpg_objects.js (Game_Temp, Game_System, Game_Timer, Game_Message))
Part 8: https://rpgmaker.net/articles/1393/ (rpg_objects.js (Game_Switches, Game_Variables, Game_SelfSwitches, Game_Screen, Game_Picture, Game_Item))
Part 9: https://rpgmaker.net/articles/2615/ (rpg_objects.js (Game_Action, Game_ActionResult))
Part 10: https://rpgmaker.net/articles/2694/ (rpg_objects.js (Game_BattlerBase))
Part 11: https://rpgmaker.net/articles/2770/ (rpg_objects.js (Game_Battler))
Part 12: https://rpgmaker.net/articles/2774/ (rpg_objects.js (Game_Actor))
Part 13: https://rpgmaker.net/articles/2778/ (rpg_objects.js (Game_Enemy, Game_Actors, Game_Unit))

Hopefully this will be helpful to people just starting out or who want to understand a bit more about how MV does what it does! Eventually I'll even be tearing down the basest of the base classes like the content of pixi.js and the core classes like Window and Bitmap.

Nice to see you back. If this is as good as Slip into Ruby, it will be awesome.

Well funnily enough Archeia I'm bringing both my tutorial series out of retirement and rebooting them as videos, possibly!
That is great news! With souls 70+ youtube scripting tutorials not available anymore this would be so nice for the community :LZSexcite:

That sounds awful since I prefer easy to read documentation especially when I have hearing problems. Here's hoping it has a transcription :'D

I wanted to ask, I loved your original Ruby tutorial. Do you think it would be worth reading both tutorials for both languages, or primarily stick with learning Javascript?

With a lot of applications I'm familiar with (InMoov GUI for example), it requires knowing both Python and Javascript. Definitely in a very different place now from when I was first wanting to do game script. I know html, css, ruby, shell, python, crystal, and Julia.

Maybe it's just a psychological think, thinking game scripts would be way harder.

I'm not sure how much you'd get out of reading both unless you plan to use both VX Ace and MV for game development. If you're set on one engine, I'd focus on the tutorials for that engine. That said, there's never any harm in knowing more than one programming language.

So I'd written part 9 and submitted it, then realised what I'd written was part 7, which I actually wrote on the 30th of April 2017. I actually wrote part 8 as well, but I hadn't updated this forum thread. That's what I get for not double-checking what my last entry was. XD

Worry not though, part 9 is being written properly as we speak and should be up tomorrow or Friday.

Of course! I'd be more than happy for you to do so.

Part 9 should hopefully be up today, I had a busy week so I wasn't able to do as much on it as I'd hoped.

Just to let you all know, I'm picking this and Slip into Ruby back up. I'd written part 9 but accidentally covered classes I'd already done, which I'll need to fix soon.

Edit: Rejoice! Part 9 is finally done and uploaded.

Written documentation remains the best for technical explanations, videos are awful, that's the plague of RMMV 90% of the plugin documentation is a 3mn video and that's it. And you need to watch that 3mn video, 10 times... Obviously, I know your videos would be much more consistent than this but still...

If you do videos, please keep your written format as well (a pdf file in the YT description for example).

Anyways, thank you for your work and wish you well... :)

Oh yeah, if I ever did start doing videos they would have full text transcripts available too.

I want to learn Javascript to create a custom menu, but I don't really know where to start.
One uncomfortable truth that has withstood the test of time, is how most people will stand by while they see a crime happening, unless it's illegal to stand by. We probably wouldn't have stories about "special heroes" or games about heroes if the "everyday common folk" were largely capable of being heroes. Heroes face dangers that most people are not willing to.
I'm having toooo much fun designing the new MP (Mental Psyche) system. I've only worked it out for enemies so far, but it's fun to stun them, then go after their MP and delete them instead to farm for better item drops.
anyone know of a place I can promote my game? sorta like game awards but for indie devs, like a place where I can drop a trailer and like stir up some hype
