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?

Copy code

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
