Cross Platform?

anon_84962506 · September 28, 2010, 9:20pm

Hey All,
I have some code we are porting from a Unity WebPlayer game to iOS in Unity3. In particular I am having issues with our UI system. It runs fine in the editor, stand-alone builds and web player builds but crashes hard on the device. I fear it stems from this message in my GDB output.

position - byteStart != info.byteSize

Is there any black magic I can use besides Debug.Log to figure this out? I submitted a bug, case #374302, on Sept. 16th but have not heard anything about it.

Any help would be greatly appreciated I have already spent 3 days spinning my wheels on this. Below is my GDB log.

you have 3 EXC_BAD_ACCESS
these normally signal that you have null reference exceptions (ie try to access objects that are null)

anon_84962506 · September 28, 2010, 10:21pm

Yes this appears to be stemming from a failed prefab instantiation.

Here’s what I’ve tried with similar results, minus the EXC_BAD_ACCESS.

WWW an assetbundle and instantiate a prefab out of it.
Resources.Load the prefab and instantiate it.
Put the prefab in the scene.

The object in the prefab is not instantiated on device but all three work fine in editor. I just get position - byteStart != info.byteSize.

what I see is that the path to the asset bundle makes totally no sense.
on the desktop, yeah potentially
on the iphone: near granted big nope

anon_84962506 · September 28, 2010, 10:51pm

I include a reference to a folder of asset bundles in my xCode project. This is not how it will be in production just a crutch to get this project off the ground. I successfully load materials and some particle emitter prefabs from there.

Dreamora · September 28, 2010, 10:57pm

can’t comment on that, but I can say that from the path you use it might not be present at all on the device (path wise). You can use System.IO.File.Exists(…) to check that

anon_84962506 · September 28, 2010, 11:03pm

It seems to think it is there. I am really worried about this.

position - byteStart != info.byteSize
(Filename: /Applications/buildAgent/work/68355d6e5d19d587/Projects/…/Runtime/Serialize/SerializedFile.cpp Line: 900)

If I remove the script from the GameObject in the prefab I stop getting this error. How could I go about debugging this error? I have tried the Debug.Log tactic and It looks like it is happening between the end construction of the script’s monoBehaviour and the beginning of it’s awake().

how i can load textures from an Xcode folders ( like raw video )? AssetBundles?

i have big out of memory problem with a lot of textures for an iPad project.

thank you

Dreamora · October 26, 2010, 12:31pm

a video is no texture and you can not load it like this (and raw is not a supported texture format - png or jpg should work though)

you can load real textures through WWW for example, accessing the files in the applications data folder and alike.
in case of textures you can additionally use System.File.ReadAllBytes and Texture2Ds LoadImage

system · October 26, 2010, 12:40pm

thank you Dreamora, i try to explain better.

Is there a way to load textures from Xcode folder and not from a website?
Unity crash with Out of Memory when i try to build after i have added more textures into the project.

I have to install iPad project with ad Hoc distribution with no wifi available.

Dreamora · October 26, 2010, 12:50pm

WWW can load local files, just use the file:// protocol.

but if you are having out of memory on building your project is totally out of scale for an iOS project as you must be overdriving it rather heavily.
A warning when loading from outside: your textures will eat several times the memory they would need if they were in the project

and you can not install anything on devices over anything but USB anyway unless its on the appstore so no prob there

system · October 26, 2010, 1:01pm

What is the right path ?
In other words where i can put the textures in Xcode project folders?

sorry, but i’m trying to find documentation without success.

In any case thank you

Dreamora · October 26, 2010, 1:10pm

never experimented with that I fear but it will end with something thats “file://” + application.dataPath + xxxx

system · October 26, 2010, 5:33pm

i will try it

Thanks
