I am try to make this collision with multiple balls work,but I am not understanding how to get it.

Is there anyone who has a suggestion for me?

I would be so helpful

This is my code.

Thanks! :)

float [] ballFallX = new float [0];
float [] ballFallY = new float [0];
float circleX, circleY;
int x=50;
float ballspeed;
int i=1;
int triangleX=500;
int triangleY=300;
boolean alp=true;
float[] xnew=new float[5];
float[] y=new float[5];
float[] speed= new float[5];
void setup() {
size(700, 700);
ballspeed=5;
frameRate(40);
for (int i=0; i <5; i++){
xnew[i]=random(width); //random position between 0 and the width
y[i]=random(height);//random position between 0 and the heigth
speed[i]=random(1,5); //the star will have a random speed
}
}
void draw() {
background(0);
for (int i=0; i <5; i++){
ellipse(xnew[i],y[i],40,40);
y[i]=y[i]+speed[i]; //here I am going to move the star on y
if(y[i]>700){ //here we say that if it goes out of the screen it has to jump back
y[i]=0;
}
circleFunc();
triangleX= x;
triangleY=600;
fill(0, 10, 200);
triangle(x+20, 675, triangleX, triangleY, x-20, 675);
}
}
void keyPressed() {
if (key == CODED) {
if (keyCode == RIGHT) {
x+=20;
}
else if (keyCode == LEFT) {
x-=20;
}
else if (keyCode == UP) {
ballFallX = append(ballFallX, triangleX);
ballFallY = append(ballFallY, triangleY);
}
}
}
void circleFunc() {
for (int i=0; i<ballFallX.length; i++)
{
fill (200, 0, 111);
ellipse(ballFallX[i], ballFallY[i], 10, 10);
println(i + " THis is the number of ball in the array");
/*
if (abs(circleX-triangleX)<50 && abs(circleY-triangleY)<50)
{
alp=false;
println(alp+" after test");
}
if (alp ==false)
{
ballFallX[i]=100;
ballFallY[i]=100;

fill(0,0);
println(alp + " in function ");
}
*/
circleX=ballFallX[i];
circleY=ballFallY[i];
// println ("Here is the X array " +ballFallX[i]);
ballFallY[i]-=ballspeed;
}
}
