I'm trying to get my background (a png file) to appear on the background of this file and it doesnt seem to work with my moving ball animation. here is my code so far.
I was trying to get the background to form while the ball is bouncing and I just cant seem to get it right. Here my code so far. Please help if you can. I am an extreme beginner at processing.
import processing.opengl.*;
float xpos;
float ypos;
int ballWth ;
int ballHgt ;
float xspeed ;
float yspeed ;
PImage bg;
void setup(){
size(800, 600, OPENGL);
smooth();
background(0);
strokeWeight(10);
for(int i = 0; i < width; i++) {
float r = random(255);
float x = random(0, width);
stroke(r, 100);
line(i, 0, x, height);
}
save("background.png");
bg = loadImage("background.png");
noStroke();
frameRate(200);
smooth();
xpos = width/2.0;
ypos = height/2.0;
xspeed = .3+random(2.5);
yspeed = .3+random(2.5);
ballWth = 80;
ballHgt = 80;
}
void draw(){
smooth();
background(0);
strokeWeight(10);
for(int i = 0; i < width; i++) {
float r = random(255);
float x = random(0, width);
stroke(r, 100);
line(i, 0, x, height);
}
// Animation
background(123);
fill(0, 162, 142);
ellipse(xpos, ypos, ballWth, ballHgt);
xpos += xspeed;
ypos += yspeed;
if (xpos >= width || xpos <=0){
xspeed *= -1;
}
if (ypos >= height || ypos <= 0){
yspeed *=-1;
}
}
