I looked at the Away3D book and all the classes involved extensively
this afternoon and evening but it did not seem to be setup for what I
wanted to do, in the end I have had to directly modify Loader3D but
very unhappy to do that, added this public method I tried some tricks
but private in as3 really is a pain... there is no sensible way to get
round it! Probably needs some testing... maybe there is a better
approach?
// add to Loader3D
public function get fractionTextureLoad(): Number
{
return _loadQueue.currentItemIndex * 1 /
_loadQueue.numItems + ( _bytesLoaded /_bytesTotal ) /
_loadQueue.numItems;
}
// and my loader is
package loaders
{
//TODO: remove unused imports

public var fraction: Number;
public function ColladaLoader( _file: String )//, _ratio:
Number )
{
//ratio = _ratio;
file = _file;
}
public function load()
{
loader = Collada.load( file, { scaling: 1,
bothsides: false } );
loader.loaderSize = 0;
loader.addEventListener( Loader3DEvent.LOAD_SUCCESS,
loaded );
loader.addEventListener( Loader3DEvent.LOAD_ERROR,
onError );
loader.z = -2000;
fraction = 0;
loader.addEventListener( Loader3DEvent.LOAD_PROGRESS,
loaderProgress );
}
private function loaded( e: Loader3DEvent )
{
content = loader.handle as Object3D;
trace( content );
finished.dispatch();
}
private function onError( e: Loader3DEvent )
{
trace( 'error loading ' + file );
}
private function loaderProgress ( e : Loader3DEvent )

Thanks Rob I will take a look tomorrow morning, it's one of the main
issues I need to get sorted so our friend can get his project out
the door, which is looking nice but quite a set of downloads.
For the new build your using adobe code for the shaders, have you
considered the haXe shaders instead any thoughts on this, any tests
on performances?

Hey Justin
Loaders are getting a complete overhaul in broomstick after it was
recognised that the current implementation is 3.6 is not flexible
enough for all use cases. So things should be a lot simpler once
that area of development has been completed
For the existing approach in 3.6, the LoaderCube object is an
example implementation of a 3D 'progress bar" and should give you
all the functionality you need to have a visual output of the
loading progress - the intention has always been for LoaderCube to
be hacked and re-purposed for your own specific visual needs

Bump - no suggestions, maybe it's basic question, but not used 3d
stuff for awhile.
I think I have to "tap into the loadercube class"... what ever that
means?
Can anyone give me a headstart, as I said not working on this for
fun or money, just trying to help a friend out, so really don't
want to spend all of tomorrow rewritting away code if there is a
simple way to do this, I presume I set the collada loader running
and then somehow hook up the loadercube but not show it and then
listen on that??
We found this snipit .... but must admit it makes little sense to
me and seems rather obscure approach.
snippet:
"Hey Kakarlus
1
0
0
0.8681069768057965
1
dae/ch_dagger_1h_t1_01_base.DAE
my question is why is there a 1 up there...
ProgressEvent is fired the instant a file starts loading. However
at this
point both bytesLoaded and bytesTotal haven't been set yet. you
will be
dividing aero by aero which returns 1.
and another question,
how do i remove the cubeloader?
to get rid of it altogether is the same approach as replacing it:
obj = Collada.load("dae/ch_dagger_1h_t1_01_base.DAE",
{loader:Object3DLoader});
the loader property in the init object can be any class definition
that
extends Object3DLoader, or if you want no visual feedback at all,
Object3DLoader itself
cheers

To be honest I have always found the loaders for away a pain to
work with maybe I need to rewrite them to be user friendly, they
seem to be sort along the lines of flash's loader which I don't
like either, but maybe I just don't understand them well enough,
but was hoping to just hook into an event that tells me the amount
loaded, if I need to feed it the total that's fine but seems this
would be something most people need... rather than an event giving
random numbers.

Hi helping a friend on some away3d, but really unsure on how to
proceed with a preloader on some collada, we have one for each
section and some streaming 3d music but thats besides the point.
currently I listen to the loading..
loader.addEventListener( Loader3DEvent.LOAD_PROGRESS,
loaderProgress );
and dispatching a signal...
if( loader.handle.bytesLoaded != 0 &&
loader.handle.bytesTotal != 0 )
{
fraction =loader.handle.bytesLoaded /
loader.handle.bytesTotal;
if( Math.round( fraction ) != 1 )
{
progressed.dispatch();
}
}
but it seems to be giving results for all the assets ( all the
images in the scene ) as they are loaded so I have a yo yo loading
bar, just unsure on the best approach, do I set the collada images
to a single 0 size image by hacking the collada file and then
replace them at run time from a separately loaded swf - that would
be a real pain and not easy, do I go down the prefab route (or
tell him to), probably sorted this before but no idea where my old
code is. Was hoping there was an event I could hook into that
would save me having to do lots of work, just assumed this is a
common thing and the engine would have something set up for this.
Sorry if I should read the documents more I looked through some of
the away classes but did not find any clues in the code and
googled but did not find an clues.
Currently looking at the standard as3 away3d version would love to
play with molehill and maybe help on the haxe part but need to get
my friends project out the door in as3, and I seem to have lost
all motivation to code as3 :).
Many Thanks for any tips cheers
