hi everyone

I am new to processing and the code was meant to 2d swarm setup, but does not appear anything.

here's my code. Many thanks for your time!!!

int pop = 600;

int DIMX = 600;

int DIMY=600;

int DIMZ=600;

ArrayList <Ple_Agent>boids;

float rotX, rotY;

PMatrix3D currCameraMatrix;

PGraphics3D g3;

//PeasyCam cam;

ControlP5 controlP5;

void setup(){

size(800,800,OPENGL);

g3 = (PGraphics3D)g;

// cam = new PeasyCam(this, 600);

initGUI();

boids = new ArrayList<Ple_Agent>();

for(int i=0; i<pop; i++){

Vec3D v = new Vec3D(0,0,0);

Ple_Agent pa = new Ple_Agent(this, v);

Vec3D initialVelocity = new Vec3D (random(-1, 1), random(-1, 1), 0 );

pa.setVelocity(initialVelocity);

pa.initTail(5);

boids.add(pa);

}

controlP5.setAutoDraw(false);

}

void draw() {

background(235);

pushMatrix();

translate(width/2, height/2);

rotateY(rotY);

rotateX(rotX);

rect(-DIMX/2, -DIMY/2, DIMX, DIMY);

//buildBox(DIMX, DIMY, DIMZ);

popMatrix();

//gui();

}

void gui() {

currCameraMatrix = new PMatrix3D(g3.camera);

camera();

controlP5.draw();

g3.camera = currCameraMatrix;

}

void initGUI() {

controlP5 = new ControlP5(this);

}

void mouseDragged() {

rotX = radians(mouseY);

rotY = radians(mouseX);

}

expecting EOF, found 'DIMX'

Need help for connecting controlP5 and Custom gray scott

Hello all. I'm new at Processing.

I have been struggling to connect controlP5 and Custom gray scott which I got from open source library. Currently, I'm interested in introducing Reaction-diffusion simulation that used pollutant concentration as a starting condition of my project.

I would appreciate if someone would be able to explain a reason why the below link does not work well, that would be wonderful. I believe it works well without ControlP5 connection and don't need image attachment to sort it out this inquiry.

Thank you to anyone who is willing to help.
