How do I use processing.core in a .java?

MartensCedric

So I have import a few .java classes from another project, but I am unable to use function such as dist() and artan2() which I can use in my main pde tab, but not in my .java tabs

I thought writing "import processing.core.*" would work, but no

Are you in processing or in eclipse or something. Else? Maybe if you share your code its easier to help? :)

You either need to call them from an instance of a PApplet or, better, if they are abstract methods (like dist and atan2 if I'm not mistaken) you can call them like PApplet.dist().

..., if they are abstract methods...

You mean static: https://Processing.org/reference/static.html ;)

GoToLoop

... you can call them like PApplet.dist().

W/o using import processing.core.PApplet.*; we're gonna need its full qualified name: processing.core.PApplet.dist().

And a cool trick: w/ import static processing.core.PApplet.*;, we can directly use dist() and other PApplet's static methods & fields w/o prefixing them w/ PApplet.. :ar!
