download file problem with .pak file, vm compiles (I think) but hangs

hebdemnobad · 26-Oct-2014 16:20:46

colleagues:

I'm attempting to have the vm download a predetermined .pak file, in this case,

http://ifam.net/openspace/hybridui3/mainwindow/mainwindow.pak mainwindow/mainwindow.pak

here is the code that calls filedownload. The vm is able to resolve all the variables in these lines without indicating an error:

let "http://ifam.net/openspace/hybridui3/mainwindow/mainwindow.pak mainwindow/mainwindow.pak" -> urlstring in
downloadFile urlstring mkfun3 @loadpakfile  [viewstr loadwidget];

here is the downloadfile callback:

fun loadpakfile (url,data, p)=
	let p -> [viewstr loadwidget] in
	(
	_cacheActivate;	
	 set loadedProject.PRJ_xmlFile = XMLloadString mkUnpakProject data;
   	 setProjectCbSceneLoaded loadedProject mkfun2 @cbProjectLoaded p;
    	loadProject loadedProject viewstr nil nil nil nil 1;
   	 );
0;;

the player opens up and then hangs.

The log terminates here

File "C:\Program Files (x86)\Scol Voyager\Partition_LockedApp\tools\mediaoctopus3dplayer\mainsplash.png" isn't a BMP file : 20617 is found as file type.
_load_bitmap failed

goes on repeating itself, I suspect there is a problem with how I am handling the objurl object, with which I am unfamiliar. I thought that once the .pak file is downloaded, I can just go ahead and call

	_cacheActivate;	
	 set loadedProject.PRJ_xmlFile = XMLloadString mkUnpakProject data;
    	setProjectCbSceneLoaded loadedProject mkfun2 @cbProjectLoaded p;
    	loadProject loadedProject viewstr nil nil nil nil 1;

without having to save the unpacked .pak file, since I assumed that is handled by the loadProject function.

In any case, I welcome any guidance, I'm a bit lost in this new territory of file downloading and network communications (ui and 3d terms I comprehend, but I don't know too much so far about network communications)

thx for your help

Hi,

I don't know precisely the os3d APIs but there is an error at least in your code.

Your url is incorrect.
I assume that the last term is the destination file (the file where the content will be saved), it is not a part of the url (the address where the resource is on the server).

"http://ifam.net/openspace/hybridui3/mai … window.pak" could be the correct url
"mainwindow/mainwindow.pak" could be the destination file on the hard disk.

So, the good statment should be :

let "mainwindow/mainwindow.pak" -> destinationFile in
let "http://ifam.net/openspace/hybridui3/mainwindow/mainwindow.pak" -> urlstring in
downloadFile urlstring mkfun3 @loadpakfile  [viewstr loadwidget];

You should probably add destinationFile somewhere.

Yes, it is correct. But your url was incorrect and thus your download is corrupted.

hebdemnobad · 26-Oct-2014 17:10:54

thx Iri...so when I declare a particular file, it includes the file name and the folder above it?

I think I'm a little closer:

	let "mainwindow/mainwindow.pak" -> destinationfile in
	let "http://ifam.net/openspace/hybridui3/mainwindow/mainwindow.pak mainwindow/mainwindow.pak" -> urlstring in	
                   (	  	
		   downloadFile destinationfile mkfun3 @loadpakfile  [viewstr loadwidget destinationfile];
		   );

and here is the changed callback:

fun loadpakfile (url,data, p)=
	let p -> [viewstr loadwidget destinationfile] in
	(
	_cacheActivate;
	///do somethign with destinationfile here, I don't quite know, or perhaps I do something after unpaking the .pak file

	 set loadedProject.PRJ_xmlFile = XMLloadString mkUnpakProject destinationfile;
    setProjectCbSceneLoaded loadedProject mkfun2 @cbProjectLoaded [viewstr loadwidget];

    loadProject loadedProject viewstr nil nil nil nil 1;
    );
0;;

it looks like the vm is doing something useful, although no scene is displaying.
excerpt from log, it shows that vm doesn't hang and is unzipping the .pak file, so thx Iri for that

I 'll wait for arkeon's input on this. I'd like to teach myself more of the api, but the online documentation isn't very explanatory (I'm not complaining, you guys are so helpful. And I'm writing a tutorial about custom callbacks that hopefully will help others...I will submit it to you and arkeon.)

arkeon · 26-Oct-2014 17:34:31

this still not good

fun loadpakfile (url, data, p)=
  let p -> [viewstr loadwidget destpath] in
  (
    //save the data in the file
    _storepack data destpath;
    
    //unpak / read pak file
    set loadedProject.PRJ_xmlFile = XMLloadString mkUnpakProject destpath;
    setProjectCbSceneLoaded loadedProject mkfun2 @cbProjectLoaded [viewstr loadwidget];

    loadProject loadedProject viewstr nil nil nil nil 1;
  );
0;;

fun downloadPak(viewstr, loadwidget)=
  //can enable cache first
  _cacheActivate;
  
  let "mainwindow/mainwindow.pak" -> destpath in
  let "http://ifam.net/openspace/hybridui3/mainwindow/mainwindow.pak" -> urlsrc in	
  (
    downloadFile urlsrc mkfun3 @loadpakfile  [viewstr loadwidget destpath ];
  );
0;;

hebdemnobad · 26-Oct-2014 17:37:18

Thx arkeon I'll try that this evening

arkeon · 26-Oct-2014 17:37:42

The cache is enable here to do not unpak / overwrite into the default user partition.
So the files are unpaked in the cache partition.

hebdemnobad · 27-Oct-2014 01:37:48

thx arkeon, I think I''m closer but the project is not loading.

before I get to what I encountered.....where exactly is the cache partition....in Usm.ini, the code says cache ./Cache 256, but i don't see such a folder in my Openspace or Partition_LockedApp folders

back to my code, ...I put a flag in the pakloaded function:

fun loadpakfile (url,data, p)=
	let p -> [viewstr loadwidget destpath] in
	(
	//save the data in the file
    _storepack data destpath;
    _fooS "pak file downloaded";
  	  _DLGMessageBox _channel mainWindow.EDW_win "pak file downloaded" "pak file downloaded" 0;
  	 //unpak / read pak file
    set loadedProject.PRJ_xmlFile = XMLloadString mkUnpakProject destpath;
    _fooS strcatn "pak file downloaded and unpacked from: ":: destpath :: " "::nil; 
    setProjectCbSceneLoaded loadedProject mkfun2 @cbProjectLoaded [viewstr loadwidget];
    loadProject loadedProject viewstr nil nil nil nil 1; 
    );
0;;

and the console is displaying

"pak file downloaded and unpacked from: mainwindow/mainwindow.pak", so the .pak file is downloading successfully

however the cbProjectLoaded function is not being called (I assume the scene is not loading).

I put flags in cbProjectLoaded and the cbPlugLoaded functions, but neither are executing...the vm isn't getting further than downloading and unpacking the .pak file.

fun cbPlugLoaded(trm, p)=

  let p -> [viewstr loadwidget] in

  if bPluginsLoaded then

  (

    _fooS "plugins have all loaded";
    _deltimer trm;

    //SO3WidgetDestroy loadwidget;

    V3DsetCbResizeView viewstr @cbPlugView3dResize;

    0;

  )

  else nil;

  0;;





fun cbProjectLoaded(project, p)=

    	  _DLGMessageBox _channel mainWindow.EDW_win "project loaded callback executed" "project loaded callback executed" 0;
    	  _fooS "projected has been loaded, triggering plugloaded callback";
    	  _rfltimer _starttimer _channel 100 @cbPlugLoaded p;
  

  0;;

Hi, the cache is here as you can see in the log
C:\Users\Daniel Green\AppData\Local\Scol Voyager\Cache

did you call that earlier in the code ? : set loadedProject = crProject sCurrentScenePath nil 1;

Thx I'll try that in around an hour and report back.

hebdemnobad · 27-Oct-2014 13:57:34

Thx arkeon it works!!!!!!! Now to build a download bar for the .pak file and a common interface for loading files from the openspace3d partition and web based .pak file.

In Scol, a new type object can be created on the fly. It will be added to the basic types like I, S, Chn, Srv, ObjWin, etc and available in the channel where it is created.
To define it, a way is to define a structure (keyword struct).
Some fields are defined in a structure, these fields are seen like functions by the VM.
Once done, you can use this new type.
Always, the first thing to do is to initialize each variable (locale and globale) which uses this new type. Otherwise, the variable will be always nil, even if you try to set it later.

OS3D define itself a lot of specific types like the type named "Project". Project is a structure (os3dlib / os3dstruct.pkg). To avoid to initialize it manually each time, Arkeon has written a function "crProject".
You must call it at first for each new Project variable.

If you are interested by that, you can read the wiki : http://redmine.scolring.org/projects/tu … es_in_Scol

I've also written this in the wiki, this may be inspirational.

hebdemnobad · 27-Oct-2014 15:09:04

thank you Iri

the lesson I take from this thread is always look at each and every function being called.
I know how to make structs now, but I'm not the best at understanding them when I encounter a call to a function in another file. I've looked at the crProject function and now understand, it's a short way of creating a Project struct without assigning values to all of the fields manually.

Thanks for the link to the slider bar tutorial and the repository of tutorials. It never hurts to be reminded (again.) For a loading bar, I prefer just a rectangle.

I will post my question about creating a download bar for a .pak file in a separate thread.

hebdemnobad · 27-Oct-2014 15:31:12

and this is the working code, with some notes as a help for beginning coders and as a reminder to myself (always check to see that ALL structs are initialized, or instanced)

hard coded download of an arbitrary .pak file.....first make the vm begin to download it

//code..
let "mainwindow/mainwindow.pak" -> destpath in
  let "http://ifam.net/openspace/spacemanshooter1/dan_no_mohawk/spacemanwithtank.pak" -> urlsrc in	
  (
    _cacheActivate;
  	downloadFile urlsrc mkfun3 @loadpakfile  [viewstr loadwidget destpath ];
  );
//code..

when the file is downloaded, loadpakfile is called. since it only passes the downloadFile url and data to the callback 2 parameters), and I need to pass the view structure, loading widget, and destination path to it, I use mkfun3 and so I can add a third parameter, the tuple [viewstr loadwidget destpath ].

here is the loadpakfile function. p is the third parameter, which I used mkfun3, so I break p into its parts, [viewstr loadwidget destpath ], so each object in the tuple can be used anywhere in the function.

fun loadpakfile (url,data, p)=
	let p -> [viewstr loadwidget destpath] in
	(
	//set scene_is_loaded global  variable to opening a new file will reinitialize scene
	set scene_is_loaded = 1;	
	//save the data in the file
    _storepack data destpath;
    _fooS "pak file downloaded";

  	 //unpak / read pak file
    set sCurrentScenePath = destpath;

    set loadedProject = crProject destpath nil 1;
    set loadedProject.PRJ_xmlFile = XMLloadString mkUnpakProject destpath;
    _fooS strcatn "pak file downloaded and unpacked from: ":: destpath :: " "::nil; 
    setProjectCbSceneLoaded loadedProject mkfun2 @cbProjectLoaded [viewstr loadwidget];
    loadProject loadedProject viewstr nil nil nil nil 1; 
    );
0;;

I didn't change cbProjectLoaded or any subsequent callbacks.
