The following code experiences no technical difficulties, but the font baskerville doesn't seem to apply in Javascript mode. Any ideas?

PFont Font;

void setup(){

size(1300,800);

background(240,255,240);

}

void draw(){

Font = loadFont("Baskerville-48 . vlw");

textFont(Font);

text("US Population Chart :1900-2000", 300, 200);

strokeWeight(4);

stroke(60,179,113);

line(50,750,50,50);

line(50,750,1250,750);

for( int i=1 ; i<12 ;i++){

textSize(20);

fill(255,127,80);

text( int(1890+10*i), i*100, 775);

}

for( int i=1 ; i<12 ;i++){

textSize(15);

fill(255,127,80);

text( int( i-1)*50 + "M", 10 ,750-(( i-1)*100));

}

stroke(60,179,113);

strokeWeight(4);

fill(255,160,122);

rect(75,750-(76*2) ,100,76*2);

rect(175,750-(92*2) ,100,92*2);

rect(275,750-(106*2) ,100,106*2);

rect(375,750-(123*2) ,100,123*2);

rect(475,750-(132*2) ,100,132*2);

rect(575,750-(152*2) ,100,152*2);

rect(675,750-(180*2) ,100,180*2);

rect(775,750-(205*2) ,100,205*2);

rect(875,750-(227*2) ,100,227*2);

opacity loop?

So I understand how to use opacity +=1 to increase the opacity of the color, but what can I do to create a loop to decrease the opacity back to 30 when it hits 100, and then bring it back to 100 again? Do I have to use a boolean statement? How?

Thanks!!!

Functions affect each other?

So I did two functions in my code, one is the thing moving in circular motion, another one is moving in a wave form. I don't want the alien1 function to redraw the background, but I do want the alien2 function does. But looks like they are always affecting each other. Any solutions? Thanks!!!!

float x1;

float y1;

float x2;

float y2;

float r1 = 100;

float rc = 20;

float rc1 = 10;

float theta = 0;

float[] rs = new float[5];

float[] gs = new float[5];

float[] bs = new float[5];

int i = 10;

int j = 0;

int k = 100;

void setup(){

smooth();

size(400,400);

background(33,33,200);

for (int i = 0; i <rs.length; i ++){

rs[i] = random(0,255);

}

for (int j = 0; j <gs.length; j ++){

gs[j] = random(0,255);

}

for(int k = 0; k <bs.length; k ++){

bs[k] = random(0,255);

}

}

void draw(){

alien1();

alien2();

}

void alien1(){

translate(width/2,height/2);

background(33,33,150);

float x1 = r1 * cos(theta);

float y1 = r1 * sin(theta);

stroke(0);

fill(255);

triangle(x1,y1-1.5*rc1,x1-1.5*rc1,y1+0.75*rc1,x1+1.5*rc1,y1+0.75*rc1);

stroke(0);

fill(255,20,20);

ellipse(x1,y1,rc1*2,rc1*2);

stroke(0);

point(x1,y1);

theta += 0.05;

}

void alien2(){

translate(-width/2,0);

x2+=2;

float y2 = cos(theta)*height/2;

stroke(i,j,k);

fill(255);

triangle(x2,y2-1.5*rc,x2-1.5*rc,y2+0.75*rc,x2+1.5*rc,y2+0.75*rc);

stroke(i*20,j*2,k*40);

fill(i*20,j*2,k*40);

ellipse(x2,y2,rc*2,rc*2);

stroke(0);

point(x2,y2);

theta +=0.01;

if(x2 > width){

i = (i+6) % rs.length ;

j = (j+6) % gs.length;

k = (k+6) % bs.length;

x2 = 0;

}

Here is the code for one of my classes, it doesn't run and keeps telling me found one too many { characters without a } to match it...Maybe it's very obvious but i just cant tell...

class evil{

float x1;

float y1;

float x2;

float y2;

float x3;

float y3;

float speedX;

float speedY;

color c;

evil(){

c = color(255,0,0);

x1 = random(width);

y1 = random(height);

x2 = x1 - 6;

y2 = y1 + 10;

x3 = x1 + 6;

y3 = y1 + 10;

speedX = random(-5,5);

speedY = random(-5,5);

}

void display(){

stroke(c);

fill(c);

triangle(x1,y1,x2,y2,x3,y3);

}

void move(){

if(x1 < 0 || x1 > width){

speedX = speedX*-1;

}

if(y1 < 0 || y1 > height){

speedY = speedY*-1;

}

x1 += speedX;

y1 += speedY;

x2 += speedX;

y2 += speedY;

x3 += speedX;

y3 += speedY;

}

void caught(){

x1 = random(width);

y1 = random(height);

x2 = x1 - 6;

y2 = y1 + 10;

x3 = x1 + 6;

y3 = y1 + 10;

score -= 1;

}

}

Question about expand array

I am creating an array of cells, what i want is once mousepressed, one cell becomes two, then each of the two cells becomes two , so the quantity of the cells doubles everytime you press the mouse. I want to use expand function to double the size of the array,
Here is my code(I have a cell class created already):

cell[] cells;

void setup(){

size(600,600);

smooth();

cells = new cell[1];

cells[0] = new cell(300,300,50);

}

void draw(){

background (255,235,205);

for (int i = 0; i < cells.length; i++) {

cells[i].grow();

cells[i].move();

cells[i].display();

}

}

void mousePressed(){

cells = (cell[])expand(cells);

// not quite sure what I should put in here?

}

}

Thank you for your help!
