Hi,

Thanks for the great tutorial. I’m just starting to learn AS3 and Papervision for some projects. I have one question:

The files work just fine, i’ve applied a new texture to the cow and it loads just fine, but when i try to replace the original .dae file with a model i need (also .dae, i just replace yours and keep the same name “cow.dae”), i get an error:

“TypeError: Error #1009: Cannot access a property or method of a null object reference.
at org.papervision3d.objects.parsers::Collada/buildObject()

at flash.net::URLLoader/onComplete()
”

What’s this about? how can i make it work? Any ideeas?

Thanks a lot :)
Stefan

I am an experienced 3d artist, but new to actionscript in general.

Simple question; I get it to compile without errors, but get a blank window.

Where do I set up the texture + model so that it loads it?

So can you animate the separate parts of the loaded object? In this example – can you make the bell on the cow’s neck swing, or make her walk etc.?

I change .dae

but

INFO: Viewport autoScaleToStage : Papervision has changed the Stage scale mode.
INFO: BitmapFileMaterial: Loading bitmap from daeModel/guy.jpg
ERROR: BitmapFileMaterial: Unable to load file daeModel/guy.jpg
ERROR: COLLADA file load error

Can you help me?

Hi Wolf,

don’t be afraid, the rotation instruction are only called one time in the constructor (and so, applied one time only). If you wanna see the cow rotating, just copy paste

cow.pitch( -10);

in the rendering part (not because it call the render function, but because this function is called every frame. Any recurring instruction make the job done).

Btw, you can also use cow.yaw(n), cow.rotationX += n, etc.

[...] post, I plan to go through it more fully later! Btw, “cow in the sourcecode is a reference to a tutorial where i first learned to add colladas in papervision. Use something like the code in that tutorial [...]

Hi,

I’ve used my own model instead of the cow, everything seems to load perfectly except it doesn’t rotate. I’ve copied paste the exact same codes. Any ideas why? thanks !!

Can this load .png textures that have transparency?
