Hey Dave
this is a problem we are aware of - a tip i have is to add your loader to
teh scene like this:
scene.addChild(loader.handle);
the handle property of the loader contains either the loader obejct itself,
or the loaded object (if the object loads instantaneously).
however, this doesn't fix the problem of a load success event being missed
because it is fired before the listener can be setup! There is actually a
mod in the latest updates that is designed to counter this and other issues
with the loading system in Away3d, and the basic premise is this:
loader = Max3DS.load("assets/f360.3ds");
loader.addOnSuccess(onSuccess);
scene.addChild(loader);
is now equal to
loader = new CubeLoader();
loader.addOnSuccess(onSuccess);
var max3DS:Max3DS = new Max3DS();
loader.loadGeometry("assets/f360.3ds", max3DS);
scene.addChild(loader);
this means you can be sure no object success event is missed. As an added
bonus, any properties for the loader and / or parser can be set on the
relevant instances using typechecked property setters - no more relying on
the init object. Should hopefully please the purists among you :)
These and other updates will be detailed in a full update email when
everything is ready for launch.
cheers
Rob
