Hello I have a little mini project and i need help concerning making once object go from one object into another. I have two scripts here. The first is the file i will be submitting for my project and its a box shooting and once it detects the circles, the circles disappear. Once the circle is disappeared i would want this explosion to happen but i don't know how to go about that. Here is the first script.
float px, py;
float vx, vy;
float minX, maxX;
ArrayList bullets;
int cols= 1;
int rows =2;
int cols_select;
int rows_select;
Alien[][] aliens = new Alien[cols][rows];
int deadAliens=0;
int lastGuy=0;
void setup(){
size( 600, 600, P3D );
bullets = new ArrayList();
minX = 150;
maxX = 450;
vx = 2;
vy = 2;
px = minX; // position px in minX at the start
py = 100 ; // posiiton py in the middle of the sketch
for (int i=0; i< cols; i++){
for (int j=0; j<rows; j++){
aliens[i][j] = new Alien(100, 300, 300, 360, i*100, j*150, 200,1);
}
}
fill(0,200,0,100);
}
void draw(){
background(255);
for (int i=0; i< cols; i++){
for(int j=0; j<rows; j++){
aliens[i][j].display();
aliens[i][j].move();
aliens[i][j].shift();
aliens[i][j].exitStageLeft();
}
}
for (int i=0; i < bullets.size(); i++) {
Bullet b = (Bullet) bullets.get(i);
b.display();
b.fire();
if(b.finished()){
bullets.remove(b);
}
for (int k=0; k< cols; k++){
for(int j=0; j<rows; j++){
if(b.intersect(aliens[k][j])){
bullets.remove(b);
aliens[k][j].destroyed();
deadAliens=deadAliens+1;
}
}
}
}
// Move box to x,y,z
pushMatrix();
fill(0,200,0,100);
rect(250,550,20,20);
popMatrix();
//Draw a box with size 50
}

boolean intersect(Alien a){
float distance = dist(xpos,ypos,a.true_xpos,a.true_ypos);
if(distance < 20){
return true;
} else {
return false;
}
}
}
class Spaceship{
//declare variables

float xpos;
float ypos;
//constructor

}
void display(){

ellipse(xpos,ypos,50,50);
}
void move(){
xpos=mouseX;
noCursor();
}
void limit_x(){
if(mouseX<100){
xpos=100;
}
if(mouseX>(width-100)){
xpos=(width-100);
}
}
void lastGuy(){
println(deadAliens);
if(deadAliens==cols*rows-1){ //changed this line here to match global variables
lastGuy=1000;
}
else {
lastGuy=0;
}
}
}
The second script is what i want the explosion to be once the circle is gone.
int num = 300;
float[] px = new float[num];
float[] py = new float[num];
void setup(){
size(400,400);
for(int i=0;i<num;i=i+5){
px[i]=200;
py[i]=200;
}
}
void draw(){
background(200);
for(int i=0;i<num;i=i+1){
px[i] = px[i] + random(-2, 2);
py[i] = py[i] + random(-2, 2);
constrain(px[i],0,100);
constrain(py[i],0,100);
ellipse(px[i],py[i],10,10);
}
}
