Doesn't work either. I also tested using a cube-primitive instead of
my model, but it still jumps back to start after having reached the
third Vector3D ("pEnd").
New code:
[…]
public function followPath(pathVectors:Array) //Called by the
Document Class after some Event
{
if (this.pathAnimator == null)
{
Var path:Path = new Path(pathVectors);
this.pathAnimator = new PathAnimator(path, this,
{ alignToPath:true } );
trace("eagle's Path = " + pathVectors[0] + pathVectors[1] +
path.array[2] + " | " + path.array[3] + pathVectors[4] +
pathVectors[5] + " | " + pathVectors[6]);
this.addEventListener(Event.ENTER_FRAME, enterFrameHandler);
}
}
[…]
New trace:
Eagle's Path = Vector3D(0, 0, 0),Vector3D(26.135709113441408,
56.92195810116378, 300) ,Vector3D(26.135709113441408,
56.92195810116378, 600) | Vector3D(26.135709113441408,
56.92195810116378, 600),Vector3D(29.517402342494407,
137.12164446189104, 900) ,Vector3D(29.517402342494407,
137.12164446189104, 1200) | Vector3D(29.517402342494407,
137.12164446189104, 1200), ...
I kind of solved the problem by simply giving the PathAnimator only
one PathCommand at a time. Once my model reaches the end of one path
segment it gets handed the next one. So instead of one big path I
divided it into the smallest possible chunks. That works, but it leads
to the next problem: As the path segments are of different lengths,
they make my models movement speed vary from segment to segment. But I
think I will find a way to handle that.
Nethertheless I'm still curious why the PathAnimator doesn't work as
it should (in my case). So if you, Fabrice, or anybody else has got an
idea, I'd love to test it :) .
