Roadmap

Done

The "heart of the program"
Tree of "Nodes" similar in spirit to Godot Engine with a component system similar to Defold!
Particular graphics nodes for the graphical interface in the same tree (so there, not like in Defold at all)
I will give a more thorough explanation at the beginning of the documentation but this tries to respond to criticisms that I would have to make both in Godot and Defold
It’s logical: since I’m doing a new thing!

GUI system with a management of themes that can be changed at any time (all widgets update automatically).

Visualization of the tree of nodes and components in progress (same principle in the spirit as in Godot)
The output is in the console for now but will be in a widget when it is available.

Error messages for debugging in a particular function (same as above).

Functions pLoad...(or methods)
(automatic waiting for file loading with a scroll bar)

Management of keyboard entries with possible modifications during the program’s progress
(notably to manage the different keyboards / languages).

User language detection (Javascript)

In progress

local git

 Date (day/month/year)
9/4/25 - #21. Preload Java and JS ok
21/4/25 - #21.4. Keyboard inputs

Project on hold: I had to take care of other things for a while!

4/8/25 - #22.4. & #22.5.: Responsiveness of Java code with the same method as Javascript.
Not ok without windowRatio() in Java because width and height don’t seem to update in Java!
Reported in the Processing Forum
5/8/25 - #22.6. : JAVA-JS compatibility / language detection in the browser in JS
5/8/25 - #22.7. : removeItem() removed from JS specific code
11/8/25: #22.9. use of instanceof, remove NodeType, create WidgetType
12/8/25 - #22.10 prepaAI: Responsive now works without windowRatio() with P2D (thanks to the Processing Forum)!

I try to use an AI for transpilation : Processing to P5js

12/8/25: Translation from Java code to JS with OpenIA

15/8/25 : Breaking News (lol) : I've used (to try) Gemini IA... and the translated Java #22.10 version almost works in P5js (with minor modifications !) : investigation in progress ! see here

The main problem with openIA was that I couldn’t send everything at once.

The Prompt (translated from french) asked to Gemini

Do the translation from Processing to P5JS of the code following line:
// START CODE
Translate only the syntax (do not change the code, do not modify the functions, do not add functions)
Do not add or edit comments.
The part of the code located between the line
//----------------SPECIFIQUE JS start-------------
and the line
//----------------SPECIFIQUE JS end-------------
is not to be translated because it is already in P5js
Variables declared in java but not initialized to a value must be declared and initialized to the null value.

--> followed with all the Java + JS code (all the tabs in a single text)

The modifications after the work of Gemini

• The code blocks that were initially in tabs had to be put in the correct order for javascript to accept them. The order of the class declaration... does not matter in Java since it starts by reading all the source code to list the classes before rereading everything to take into account what is inside.
• The path to the images must have been specified.
• There remains just the error "n is not a function" and the tree of nodes and components are not written in the JS console like in the Java version (it works fine in the JS #21 version)

Investigation !

16/8/25 : Gemini did not write a ‘let’ for many variable declarations. It is perhaps this that causes problems because if variables that must be local are declared as global, it will work in most cases… but not all!

I will start again by specifying to it : Precede the declarations of new variables (those which are preceded by a type name of variables in Java such as String, float, Boolean, PFont, PImage,int ...) with the JavaScript instruction let).
+
For file uploads, precede them with their path, namely: data/

+

use the javascript strict mode

Done and it works fine (almost) !

Just an error in a function name and something Ihat I've to change in the JS part !

Fixed and no error in strict mode !

So we can use AI for transpilation sometimes to save time (provided that it can also be done without ! ).

16/8/25 - #23. Java version #22.10 translation in JS with Gemini: ok
19/8/25 - #24. Small settings in the demo
21/8/25 : #24.1. Small modifications without using global positions for the Demo to work properly

Problems with global positions in JS: investigation in progress

Then

(not necessarily in this order)

Delete ComponentType (instanceof) ?

Website: put a button / translation in French on each page

Put the project on a software forge (probably codeberg.org)

Change the name of the listen() method to listenedBy() for a better readability

Comments
Translate the French comments into English (/IA)
Write all the Javadoc comments
In the Java code, copy/paste the signatures of the methods into comments on the same line so that they end up in the JS code after a translation /IA

Improvement of the keyboard detection system to manage the simultaneous pressing of several keys
Label + Containers
AnimatedSprite2D
Sound management
Particle system (Shiffman reference)
Buttons System (Texts or images)

Button on the sketch instead of keyboard inputs (JS compatibility on smartphone)
waiting for a version of the Java app on Android
