Bad frameRate

in Programming Questions  •  1 year ago  
Does anyone know why this simple program drops my frameRate to 20-25? Am I missing something?
Copy code
  1. float ballX, ballY;
  2. float speedX = 7;
  3. float speedY = 5;
  4. int dirX = 1;
  5. int dirY = 1;

  7. void setup() {
  8.   size(900, 600, P3D);
  9.   background(200);
  10.   smooth();
  11.   noFill();
  12.   //noStroke();
  13.   //noCursor();
  14.   camera(
  15.   width/2.0, 600, 500,
  16.   width/2.0, height/2, -200,
  17.   0, 1, 0);

  19.   ballX = width/2;
  20.   ballY = height/2;
  21. }

  23. void draw() {
  24.   background(200);
  25.  
  26.   //Creates floor
  27.   fill(255);
  28.   rect(0, 0, 900, 600);

  30.   //Creates top wall
  31.   pushMatrix();
  32.   translate(width/2, -100/2, 50/2);
  33.   fill(150);
  34.   box(width + 400, 100, 50);
  35.   popMatrix();

  37.   //Creates sphere
  38.   ballX += speedX * dirX;
  39.   ballY += speedY * dirY;
  40.   pushMatrix();
  41.   translate(ballX, ballY, 6);
  42.   fill(50);
  43.   sphere(6);
  44.   popMatrix();

  46.   //Creates paddle 1
  47.   pushMatrix();
  48.   translate(60, mouseY, 15/2+5);
  49.   fill(255, 0, 0);
  50.   box(15, 60, 15);
  51.   popMatrix();

  53.   //Creates paddle 2
  54.   pushMatrix();
  55.   translate(width - 60, mouseY, 15/2+5);
  56.   fill(0, 0, 255);
  57.   box(15, 60, 15);
  58.   popMatrix();
  59.  
  60.   if (ballX >= width || ballX <= 0)
  61.     dirX *= -1;
  62.  
  63.   if (ballY >= height || ballY <= 0)
  64.     dirY *= -1;
  65.    
  66.   println(frameRate);
  67. }

EDIT: Oddly enough, commenting out smooth() increases FPS by 30+... :/

If anyone knows anyway to get it to run faster I'd really appreciate it.

Even just this will drop it down to 25-30 fps...?
Copy code
  1. int ballSize = 15;
  2. float ballX, ballY;
  3. float speedX = 7;
  4. float speedY = 5;
  5. int dirX = 1;
  6. int dirY = 1;

  8. void setup() {
  9.   size(900, 600, P3D);
  10.   background(200);
  11.   smooth();
  12.   //noStroke();
  13.   //noCursor();
  14.   camera(width/2.0, 600, 500,
  15.   width/2.0, height/2, -200,

  17.   0, 1, 0);
  18.   ballX = width/2;
  19.   ballY = height/2;
  20. }

  22. void draw() {
  23.   background(200);

  25.   pushMatrix();
  26.   translate(0, 0, -10);
  27.   fill(255);
  28.   rect(0, 0, 900, 600);
  29.   popMatrix();

  31.   ballX += speedX * dirX;
  32.   ballY += speedY * dirY;
  33.   fill(0);
  34.   ellipse(ballX, ballY, ballSize, ballSize);

  36.   if (ballX >= width || ballX <= 0)
  37.     dirX *= -1;

  39.   if (ballY >= height || ballY <= 0)
  40.     dirY *= -1;

  42.   println(frameRate);
  43. }

use
Copy code
  1.   size(900, 600, OPENGL );
instead.

with
http://www.processing.org/reference/sphereDetail_.html
you can reduce the time to draw the sphere

smooth() slows things down

there's a technique to store fixed scenery (floor, walls...) in your graphic card - could be fast. Look it up here in the forum please.

Switching to OpenGL improved FPS insanely, thanks.
