This is a very simple function and is really for a test purpose. Feel free to change it.


//Simple function to detect the keys pressed by the user. We just change the offsets and angles.
function checkKeys() {
 if (Key.isDown(Key.RIGHT)) {
  xOffset += 4;
 }
 if (Key.isDown(Key.LEFT)) {
  xOffset -= 4;
 }
 if (Key.isDown(Key.UP)) {
  yOffset -= 4;
 }
 if (Key.isDown(Key.DOWN)) {
  yOffset += 4;
 }
 if (Key.isDown(Key.INSERT)) {
  angleY -= 0.001;
 } else {
  if (Key.isDown(Key.DELETEKEY)) {
   angleY += 0.001;
  } else {
   angleY *= 0.95;
  }
 }
 if (Key.isDown(Key.HOME)) {
  angleX += 0.001;
 } else {
  if (Key.isDown(Key.END)) {
   angleX -= 0.001;
  } else {
   angleX *= 0.95;
  }
 }
 if (Key.isDown(Key.PGDN)) {
  angleZ += 0.001;
 } else {
  if (Key.isDown(Key.PGUP)) {
   angleZ -= 0.001;
  } else {
   angleZ *= 0.95;
  }
 }
}

The only thing this function does, is to change the angle and offset vars we declared in the previous page. Im also adding a bit of "inertia".

Next section is the render function.
