Problem with Processing Eclipse

in Integration and Hardware • 2 years ago

I made a great decision (I hope...) to pass to Eclipse for a more professional development.
And now I face with first professional (!) problem. I try to import this project in Eclipse but it seems doesn't recognize some function (like random, pow, vertex...).
1 - some function are outside processing.core?
2 - Plus Eclipse force me in some case to convert from float to double. Not clear, hints on this are welcome
3 - I don't fully understand how to implement the parent mechanism of PApplet?

For this post, You will have a place in my biography for sure!!!
Thanks

Have you read the Eclipse tutorials? Searched the forum for similar threads (numerous!)?
In Eclipse, your class must extend PApplet to be able to use Processing's functions. If you have a secondary class, you have to pass an instance of the PApplet, to be able to call pa.random() for example (where pa is a reference on the PApplet subclass).
Moreover, Processing makes all literal decimal numbers to be float, by appending f to them, behind the scene. You have to do this manually in Eclipse, since default in Java is doubles.

Yes I'm reading some tutorials on Processing Wiking and in CreativeCode site.
Your hints pa.random() solve some of the problems. But.... It's a little bit complicated.

If I extend the PApplet with an external Class, I notice that I must extend also the methods in which I want to use processing function...

I downloaded the project, imported it in Eclipse, made the necessary changes and corrected a few errors. Finally I got it to compile. But the output is just a blank applet viewer window. I couldn't figure out why nothing is getting displayed. Check out the modified project here.

Just downloaded. In my version remain a problem with colors, and it's slightly different from yours... I will let you know.
(Anyway, I've just granted a place in my life.)

Solved. All functional. You can download the from Eclipse projects from here.
@Manindra29: I didn't test your project but di d you try to use v and b key to set the dimension of the balls?
I had some problem with this when I run the project...
