Rotate an ellipse during mousePressed

tjhoersten

I have a football being kicked by a robot going through the goal posts. How do I make the football rotate while flying through the air? Here is my code. Thanks

int x = 80; int y = 600; int bodyHeight=110; int neckHeight=140; int radius = 45; int ny = y-bodyHeight-neckHeight-radius; int m=740; int b=558; int t=15; int h=30; void setup(){ size (1520,780); } void draw(){ smooth(); strokeWeight(2); background(204); fill(#36A6FF); //sky color rect(0,0,2000,600); //sky fill(#F6FF00);//suncolor ellipse(30,30,100,100); //sun ellipseMode(RADIUS); //neck stroke(102); //set dtroke to gray line(x+2,y-bodyHeight,x+2,ny); //left line(x+12,y-bodyHeight,x+12,ny); //Middle line(x+22,y-bodyHeight,x+22,ny); //Right //antennae line(x+12,ny,x-18,ny-43); //small line(x+12,ny,x+42,ny-75); //tall line(x+12,ny,x+78,ny+15); //Medium //Body noStroke(); //disable stroke fill(102);//set fill to gray ellipse(x,y-33,33,33); //antigravity orb fill(#FF6600);//set fill to block rect(x-45,y-bodyHeight,90,bodyHeight-33); //main body fill(102); //set fill to gray rect(x-45,y-bodyHeight+17,90,6); //gray stripe //head fill(#FF6600); //set fill to block ellipse(x+12,ny,radius,radius); //head fill(255); //set fill to white ellipse(x+24,ny-6,17,17); //large eye fill(0); //set fill to black ellipse(x+24,ny-6,3,3); //pupil fill(155); //set fill to light gray ellipse(x,ny-8,5,5); //small eye 1 ellipse(x+30,ny-26,4,4); //small eye 2 ellipse(x+41,ny+6,3,3); //small eye 3 //goal post fill (234,234,2); rect(1200,200,10,400); //left upright fill(234,100,30); //color football ellipse(m,b,t,h); //football fill (234,234,2); rect(1400,200,10,400); //right upright rect(1200,400,210,10); //crossbar fill(#26D34D); //grass color rect(0,600,2000,2000); //grass fill(#FF0000); //flag color rect(1210,200,25,10); //left flag rect(1410,200,25,10); //right flag fill(#FF6600); //pad color rect(1185,500, 40, 100); //left pad rect(1385,500,40,100); //right pad fill(0);//tee color rect(725,588,30,12);//tee //bigger eye, smaller big antenna, sky, sun, laces on the ball, upright flags, orange body color, and post pads. } //kick the football void mousePressed(){ x+=30; if (x>700){ m+=50;b+=-25;x=700; rotate(90); ellipse(m,b,t,h); } }

Compute the argument passed to rotate() based on the x position of the ball.

rotate(90);

or:

rotate(x * spinfactor);

The matrix is reset at start of draw automatically

This means you have to pass a value to rotate that makes the ball rotate even though the previous rotation is not there anymore
