unexpected token: "class name here"

in Programming Questions • 2 years ago

I keep getting the error "unexpected token:" followed by the name of the class that I just created in another tab within Processing 1.5.1.

As far as I can tell I am using the correct syntax.

Any help would be great.

import hypermedia.net.*; //UDP Library
import processing.pdf.*; //PDF Library
import processing.opengl.*; //OPENGL Library
import traer.physics.*; //Physics Library
import peasy.*; //Camera Library
import controlP5.*; //Control Buttons Library
import superCAD.*; //CAD Export Library
PMatrix3D currCameraMatrix; //define Camera Matrix Object
PGraphics3D g3; //define 3D Space detached from PeasyCam for buttons
ControlP5 controlP5; //define the ControlButton Objects
UDP udp; // define the UDP object
ParticleSystem physics; // Physics Universe!
PeasyCam cam; //PeasyCam Object
Coral coral;
ArrayList corals;
int coralIndex = 0;
void setup() {
//size(1000, 1000, P3D);
size(1000, 1000, OPENGL);
hint(ENABLE_OPENGL_4X_SMOOTH);
frameRate(30);
cursor(CROSS);
udp = new UDP( this, 6001);
udp.listen( true );
g3 = (PGraphics3D)g;
coral = new Coral();
corals = new ArrayList();
controlP5 = new ControlP5(this);
//controlP5.addSlider("mySlider", 0, 0, 0, 10, 10, 300, 50).setId(1);
controlP5.addButton("Export_OBJ", 0, 10, 80, 80, 20).setId(2);
controlP5.addButton("newMesh", 0, 10, 170, 80, 20).setId(3);
controlP5.addButton("Export_PDF", 0, 10, 240, 80, 20).setId(4);
controlP5.setAutoDraw(false);
cam = new PeasyCam(this, 500);
cam.setMinimumDistance(100);
cam.setMaximumDistance(1000);
coral.create();
coral.display();
}
void draw() {
for (int i = 0; i < corals.size(); i++)
{
Coral coral= (Coral) corals.get(i);
coral.display();
}
}
void mouseClicked() {
corals.add(new Coral());
Coral coral = (Cape) corals.get(coralIndex);
coral.create();
coralIndex++;
}

and this is the class

"class" is supposed to be all lowercase ("class Coral").
That's the only thing I can think of right now.

Re: unexpected token: "class name here"

I do believe that solved it :)

it was highlighted yellow, like a keyword as a capital, so I just kept skipping it as I checked through for errors...good to know!

Thanks so much!
