Hello i've got this script but when I run it the black scrolling circle scrolls infront of the text how do I make the text a seperate colour and have it so its infront of the scrolling ball. Also how can I make the text appear and dissapear in relation to an amount of time?
Thanks for anyhelp

//Ball variables

int x,y;

Circle myCircle2 = new Circle(x, y, 30);

Circle myCircle1 = new Circle(200, 200, 20);

//Image variables

PImage img;

void setup() {

size(500, 500);

img = loadImage("image1.jpg");

x = width/2;

y = height/2;

noStroke();

}

void draw() {

background(0, 0, 0);

image(img,0, 0);

myCircle2.x = x;

myCircle2.y = y;

y--;

if(y < -50)y = height+50;

myCircle1.x = mouseX;

myCircle1.y = mouseY;

if(dist(myCircle1.x, myCircle1.y, myCircle2.x, myCircle2.y) < myCircle1.r + myCircle2.r) {

strokeWeight(2);

stroke(0, 255, 0);

textAlign(CENTER);

textFont(createFont("Arial", 18));

text("You Lose.",width/2,150);

line(100, 100, 400, 100);

line(100, 200, 400, 200);

line(100, 100, 100, 200);

line(400, 200, 400, 100);

fill(0);

noStroke();





} else {

fill(0, 255, 0);

noStroke();

}

myCircle1.render();

myCircle2.render();



}



class Circle {



float x;

float y;

float r;



Circle(float xpos, float ypos, float radius) {

x = xpos;

y = ypos;

r = radius;



}

void render() {

ellipse(x,y,r*2, r*2);



}

}

Hello I am completely new to processing.

Anyway I found this code for a ball which scrolls down the screen but I want to make it go the other way but cant get it to move the opposite way, also what does y-- mean ? Heres the code:
```
int x;
```
```
 int y; 
```
```
void setup() { 
```
```
size(500,500);
```
```
 x = width/2;
```
```
 y = height/2; } 
```
```
void draw() { 
```
```
background(200,100,100); 
```
```
fill(100,200,100); 
```
```
ellipse(x, y, 100, 100);
```
```
 y++; 
```
```
if(y>height)
```
```
 y=0; 
```
```
}
```
```
Thanks for any help you can give me.
```
