ControlP5 and JS mode problem

in Integration and Hardware • 1 month ago

Hi there,

I'm using ControlP5 control library in my project and it works nicely in Java mode, but when I try to run it in JavaScript mode in Chrome browser it says:

Uncaught Processing.js: Unable to execute pjs sketch: ReferenceError: ControlP5 is not defined

probably the next error is related to the first too:

Uncaught TypeError: Cannot call method 'draw' of null

What I have to do to make it working on-line ?

Moved topic from Contributed Libraries.
Basically, if your sketch is doing any "import" statement, it won't run in JavaScript mode. Java libraries doesn't work with PJS.

What?

Looking at the Libraries page, I see a new kid in town: Guido was made to be compatible with the JavaScript mode...
I believe Quarks worked on his G4P library to make it JS-compatible, but I don't know if it is done.

Hi,

Thank you for your responces ! They are really helpfull !

Just tried Guido, but in Java and JavaScript modes it says:

1) in the Java mode:

The class de.bezier.guido.Interactive is incompatible with Processing 2.0.

A library code (or other code) is using registerMouseEvent() which is no longer available.

2) in the JavaScript mode:

Uncaught Processing.js: Unable to execute pjs sketch: ReferenceError: Interactive is not defined

Am I doing something wrong ? On what version of processing this library is supposed to be working ? I have Processing 2.0.18

Mmm, strange, the page mentions Processing 2.0 and last commit is only one month ago, so it should be OK with this version.

Out of curiosity, I will try it and report back.

I installed Guido via the PDE's interface, then I restarted Processing (2.0 currently).
I was able to load the examples, although they are messing up the interface.
Probably because they have a sketch.properties file that forces the PDE to load them in the JavaScript mode... which I haven't installed yet!

But by copy & paste in a clean window in Java mode, I can run the first examples, so it definitively works with Processing 2.0.

[EDIT] Yes, once I removed the sketch.properties files, the example sketches loaded and worked without problem.

How did you install Guido?

I installed it manually - I downloaded the Guido.zip file from the page the adress you gave me https://github.com/fjenett/Guido then inzipped it and moved to libraries directory in Processing folder, so when I started again my Processing it was already there.

Hope it'll help.

I don't know if the zip file is up-to-date. It is better to use the Processing's way of installing libraries, anyway, when it is available.
