Thanks, that was useful. I also realized that I wasn't aware of
maxTiltAngle and minTiltAngle properties that let me go beyond the
range of -90 and 90.
However, I find that when the tiltAngle crosses the threshold of 90,
the Z-axis flips to the other side. Here's the relevant code: How to
avoid flipping of the z axis?
override protected function CreateCamera() : void
{
m_pHoverCamera = new HoverCamera3D();
m_pHoverCamera.distance = 2000;
m_pHoverCamera.tiltAngle = 0;
m_pHoverCamera.panAngle = 0;
m_pHoverCamera.steps = 0;
m_pHoverCamera.yfactor = 1;
m_pHoverCamera.maxTiltAngle = 360;
m_pHoverCamera.minTiltAngle = -360;
m_pHoverCamera.wrapPanAngle = true;
m_pHoverCamera.target = this.m_pTrident;
m_pView.camera = m_pHoverCamera;
}
protected override function onMouseDown(evt : MouseEvent) : void
{
_mouseDown = true;
_lastPanAngle = m_pHoverCamera.panAngle;
_lastTiltAngle = m_pHoverCamera.tiltAngle;
_lastMouseX = stage.mouseX;
_lastMouseY = stage.mouseY;
}
protected override function onEnterFrame(evt : Event) : void
{
m_pPendulum.rotationZ = 45 * Math.sin(getTimer() / 500);
if (_mouseDown)
{
m_pHoverCamera.panAngle = 1 * (stage.mouseX -
_lastMouseX) +
_lastPanAngle;
m_pHoverCamera.tiltAngle = 1 * (stage.mouseY -
_lastMouseY) +
_lastTiltAngle;
}
trace(m_pHoverCamera.panAngle,
m_pHoverCamera.tiltAngle);
m_pHoverCamera.hover(false);
m_pView.render();
}
Thanks.
