Hi, trying to move my project into Intelij\*, but I can’t get PeasyCam to work.  
I’ve added the library to the project, and it correctly recognizes the PeasyCam type, but when I run the sketch I get the following runtimeException:

```auto
java.lang.RuntimeException: java.lang.NoSuchMethodError: processing.core.PApplet.registerDraw(Ljava/lang/Object;)V

```

Seems to be related to OpenGL, but without PeasyCam I have no problem running P3D sketches, and the jogl libs are available in the project.

\*Not the most reccomended path for beginners, I know, but since my job uses Intelij I’ve grown quite accustumed…

Hi, I just tried add it to my current project and it works. I have `peasycam.jar` and `peasy-math.jar` added to Global Libraries. I add

```
private PeasyCam cam;

```

to my main class which extends PApplet, and

```
cam = new PeasyCam(this, 400);

```

inside `setup()` (not inside `settings()`!). That’s all.

I somehow missed the `peasy-math.jar`… Oops.  
Thanks! Hope it’ll be helpful to some other poor fools in the future 😉

To avoid that problem, when adding a Processing library in IntelliJ Idea, I normally add the whole folder that contains the jar (instead of selecting a specific jar file), because this searches for any jars or system dependent binaries found in that folder and adds them to the project.

The exception to that is when I add the Processing core libraries (or libraries that have OS dependent versions), because I do not want to add Mac or Windows libraries since I’m on Linux. Then I manually select only these:

```
core.jar
gluegen-rt.jar
jogl-all.jar
gluegen-rt-natives-linux-amd64.jar
jogl-all-natives-linux-amd64.jar

```

The last two will depend on the OS you are targeting.
