I’m working with away3d 4. I want to create a hovercontroller with infinite tilt so i can freely rotate around an object
the bits of code below allow me to do this but when the tilt goes beyond -90 or +90 the object flips (ie appears to do an instant 180 degree rotation)
cameraController = new HoverController(camera, null, 150, 10, 2000); cameraController.minTiltAngle = -Infinity; cameraController.maxTiltAngle = Infinity;
then the mouse control is done like this
private function onEnterFrame(ev : Event) : void { // Handle hover camera if (move) { cameraController.panAngle = 0.3 * (stage.mouseX - lastMouseX) + lastPanAngle; cameraController.tiltAngle = 0.3 * (stage.mouseY - lastMouseY) + lastTiltAngle; } _view.render(); } private function mouseDownHandler(e:MouseEvent):void { stage.addEventListener(Event.MOUSE_LEAVE, onStageMouseLeave); lastPanAngle = cameraController.panAngle; lastTiltAngle = cameraController.tiltAngle; lastMouseX = stage.mouseX; lastMouseY = stage.mouseY; move = true; }

Stick this in the same folder as HoverController
It has easing on the distance and allows for an infinite tilt.
eg
camController.noFlip = true;

“-Infinity;” ???
The default values of maximum and minimum tilt are infinite. So when declaring the Hover Controler “new HoverController(camera…);” leave the max and min pan and tilt angle empty or see whats the default value (i can’t remember what it was and I don’t have away3d at this moment).

Nope the max min tilt defalut is -90 90.
To have the camera rotate without restriction then you need to set to Infinity.
The next issue is flipping at the poles, which is solved by flipping the up axis thats passed to lookAt.
Hence the little editted class above

that would be the solution, thanks john - again i can’t download that file.
Are you able to download these? I’m on a mac and i’ve tried chrome and safari - the link opens a new blank window but nothing downloads. Perhaps this forum has some issues, i was getting mysql errors when searching this morning (though that seems ok now).

[REMOVED LINK]
Just noticed
Theres an unnecessary import in that
import flash.geom.Matrix3D;
Just delete it

Thanks so much John, just got all that working. Its a beauty!
Perhaps this code should be integrated into core, its seems so useful as spinning a camera all around a model seems a pretty useful thing to do.

Hi
I get this errors:
“lib\away3d\controllers\HoverControllerJB.as(310): col: 28 Error: Incompatible override”
so I change:
public override function update():void
to
public override function update(interpolate:Boolean = true):void
but now I Have this error:
[Fault] exception, information=TypeError: Error #1009: Cannot access a property or method of a null object reference. on the line 340 because the “lookAtObject” are null.
any help ?

Tanks for the reply.

Hello!
I tried the HoverControllerJB.as as well but it doesn’t seem to work with infinite tiltangle and I was wondering how careca solved this or is there a more simple ways of achieving this?
Thanks
