Good day
Do not have any idea. How to rotate a rect in the cycle.
float a;
float fx,fy;
void setup() {
size(640, 550);
smooth();
fill(255);
rectMode(CENTER);
}
void draw() {
background(102);
translate(320, 275);
a = atan2(mouseY-height/2, mouseX-width/2);
rotate(a);
rectDraw(250,50,0.45,0);
}
void rectDraw(int r, int s, float c, float d)
{
for(float i=0; i<2*PI; i=i+c)
{
fx = r*cos(i);
fy = r*sin(i);
//This is not work everything becomes chaotic
//translate(fx, fy);
//rotate(i)
rect(fx,fy,s,s);
}
}
Please help.
