animate rotation rect and explotion

in Programming Questions • 1 year ago

Hello.

I want a rectangle to spin around it's on center.

my rect is spawning outside the screen and will aim at the center.

I want it to rotate all the way... can figure it out, please help me.

Best to do this in the class or in main?

class komet{
int a = 15;
int b = 15;
float x = 0;
float y = 0;
float komet1,komet2;
komet(float _x, float _y){
x = _x;
y = _y;
float speed = 1;
float ang = atan2(height/2-y, width/2-x);
komet1 = cos(ang)*speed;
komet2 = sin(ang)*speed;
}
void movement(){
x +=komet1;
y +=komet2;
}
void kometer(){
rect(x,y,a,b);
noStroke();
}
void collision(){
if ( dist(x, y, i1, i2) < i3) {
println("traff");
x = 1000000;
y = 1000000;
i++;
}
}
void smart(){
movement();
kometer();
collision();
}
}

this is my mainer

PImage jorden;

int e = 0;
ArrayList kometer = new ArrayList();
int x = 0;
int y = 0;
int douche = 0;
int i1 = 503;

int i3 = 62;
int i = 0;
komet k;
PFont Font;

int startTime; // for the timer to make request ever N seconds
String html = ""; // String to hold data from request

xmlRequest.makeRequest();

}
void draw() {

ellipse(i1, i2, i3*2, i3*2);

// Every 5 seconds, make a new request
int now = millis();
if (now - startTime > 2000) {
xmlRequest.makeRequest();
println("Making request!");
startTime = now;
}
jorden = loadImage("earth.png"); //Bilden
imageMode(CENTER);
image(jorden, 500, 250);
for (int i = 0; i < kometer.size(); i++) {
komet k = (komet)kometer.get(i);
k.smart();
}
Font = loadFont("PressStartK-48.vlw");
textFont(Font,48);
text(i, 25, 75);
}
// When the request is complete
void netEvent(XMLRequest ml) {
// Retrieving an array of all XML elements inside "<title*>" tags
String[] headlines = ml.getElementArray("title");
for (int i = 0; i < headlines.length; i++) {
// println(headlines[i]);
}
for (String html: headlines) {
if (html.toLowerCase().contains("2012")) {
douche++;
println(douche);
switch ((int) random(4)) {
case 0:
// top edge
k = new komet( random(width), -10 );
break;
case 1:
// right edge
k = new komet( width+10, random(height) );
break;
case 2:
// left edge
k = new komet( -10, random(height) );
break;
case 3:
// bot edge
k = new komet( random(width), height+10 );
break;
}
kometer.add(k);
}
}
