I was wondering how one would go about making a cursor that rotated so as to look in the direction the mouse is moving.

I also have code here that is like an unfolding of the cursor() function, if it would be easier to add something in this form:


void setup() {
 size(400,400);
 background(174);
 noCursor();
};

void draw () {
   fill(174,174,174);
   stroke(174,174,174);
   ellipse(pmouseX,pmouseY, 30, 30);
//erases what was previously drawn
   fill(255,255,0);
   stroke(0,0,0);
   arc(mouseX,mouseY, 20, 20, PI, PI/2);
//draws the image for the cursor where the mouse is
 
 
};

Thanks. after playing around some, I figured it out. It isn't perfect but this is the code:


void setup() {
 size(400,400);
 background(174);
};
void draw () {
 if(mousePressed) {
   delay(10);
   translate(mouseX, mouseY);
   fill(174,174,174);
   stroke(174,174,174);
   ellipse(mouseX-pmouseX,mouseY-pmouseY, 80, 80);
//to erase previous

   fill(255,255,0);
   stroke(0,0,0);
   float a = atan2(mouseY-pmouseY, mouseX-pmouseX);
   rotate(a + 9*PI/8);
//determines how much to rotate
   arc(0,0, 20, 20, PI, PI/2);
//draws pac-man
   noCursor();
 };
 
};
//when mouse is let go switch back

void mouseReleased () {
   fill(174,174,174);
   stroke(174,174,174);
   arc(mouseX-pmouseX,mouseY-pmouseY, 30, 30, PI, PI/2);
   cursor(ARROW);
 };
