Updated guide for using Processing 3 in Eclipse

espiuu

Hello, here is an updated guide for using Processing 3 in Eclipse.

https://github.com/DigitalMediaAcademy/Programming-with-Java-2016/wiki/Using-Processing-in-Eclipse

A couple more things to add in regards to using Processing once you get it set up:

• Accounting for colors by getting used to using ints and bit-masking, using individual rgb variables, or using java.awt.Color.

• Passing the PApplet to any separate Java files outside of the client class.

• importing other Processing libraries.

Please let me know if you see any errors, or suggestions for things to add.

Hot damn, thank you! For sure going to give this a try later today. I'll let you know how it goes.

At last, all the other tutorials seem to be obsolete! Thank you :)

With your technique I get this error when including P3D, any Ideas?

Edit: Could you please explain how I can add 'install' processing, so when I create a new project in Eclipse I can do New>Project>Processing?

I added a few more .jar and that solved the problem.
