How to rotate listenerOrientation

[craigbrett17]

Hi there. Love the library - think it's my favourite way of doing web audio. But... I'm having a little trouble with 3D sound, in particular rotating the listener position, representing turning the player around, etc.

From looking at the example, it's very Thre.JS specific. However, the reason I came to sono was that I found Three.js a bit too heavy for just doing simple 3D sound in the web when you're not using any visuals. So I've been trying to crack it without it. I think when I understand this all a bit more I might try upping the documentation of it a bit.

So far, I've been minorly successful making a sound pan from left to right when I rotate, except the jump is huge and it doesn't go all the way around for some reason. I think my maths is wrong here.

Here's what I have, with pov being an instance of my PointOfView class.

In index.ts:

function inGameKeyPressHandler(ev: KeyboardEvent): void {
  switch (ev.which) {
    case Key.LeftArrow:
      pov.rotateLeft(45)
      console.log("Orientation: ", pov.OrientationX, pov.OrientationY, pov.OrientationZ)
      break
    case Key.RightArrow:
      pov.rotateRight(45)
      console.log("Orientation: ", pov.OrientationX, pov.OrientationY, pov.OrientationZ)
      break
  }
}

And in PointOfView class I have:

    /** The orientation X direction of the POV */
    OrientationX: number
    /** The orientation Y direction of the POV */
    OrientationY: number
    /** The orientation Z direction of the POV */
    OrientationZ: number

    rotateLeft(degrees: number) {
        this.OrientationX -= degrees * Math.PI / 180
        sono.panner.setListenerOrientation(this.OrientationX, this.OrientationY, this.OrientationZ)        
    }

    rotateRight(degrees: number) {
        this.OrientationX += degrees * Math.PI / 180
        sono.panner.setListenerOrientation(this.OrientationX, this.OrientationY, this.OrientationZ)        
    }

Am I even close?

Sorry if this isn't the right forum to ask questions on library use, happy to move it if needs be.
