[wiznoe]

Hi all,
i want to load a scene from directory, but cannot, in the console written like this :
could not load mesh, because file could cot be opened: meshes/tipe21/house21.irr
could not open file of texture: material/wood.bmp
...
etc

i think my problem on the working directory, like in the irredit, that the working directory can be setting,
than how to change my working directory on my code?
plz anybody help me, sorry for my bad english.
thanks

Just set your working directory in IrrEdit to the directory of your Irrlicht app and have all your assets local to your irrlicht app.

[NemoStein]

Go to "Tools -> Options -> Working Directory" and set the path to the folder that your .exe is...
Close your IrrEdit and open it again...

Now should work... ;D

[JP]

And you'll have to re-save your .irr file to update the file paths in it

Yeah, i ever do that, i know to set working direktory in irredit,
but when i open scene pass openfile dialog box, all the mesh in that scene (irr file) cannot load, any idea?

[JP]

Is this in IrrEdit it won't load? Or Irrlicht?

Are the meshes actually in the correct location? And what is house21.irr? Is that actually an irr file? Keeping in mind that irr is a scene format not a model format...

after using FileOpenDialog in Irrlicht, working dir remains where irr scene file was, so you have to write:

filesystem->changeWorkingDirectoryTo("myworkingdir");

to change it back to where your root is.

filesystem is of type IFileSystem* and you can get it with device->getFileSystem();

[JP]

Yeah before you open the file dialog, cache the current working directory and then once the file dialog is closed reset the working directory to the one you cached.

Thanks a lot, i will try it.

Hi JP & Pera,
sorry, maybe i'm stupid, but i can't change the working directory in my irrlicht app.
This is my code :

Code: Select all

		case EGET_FILE_SELECTED:
				{
					IFileSystem * m_FS = device->getFileSystem();
					printf("\n#dir1:: %s",stringc(m_FS->getWorkingDirectory()).c_str());
					IGUIFileOpenDialog* dialog =
						(IGUIFileOpenDialog*)event.GUIEvent.Caller;
					
					smgr->clear();
					
					loadRumah(smgr,stringc(dialog->getFileName()).c_str());
					stringc m_WorkingDirectory = "C:\SPPK Rumah V1.4\sppk\sppk.";
					m_FS->changeWorkingDirectoryTo(m_WorkingDirectory.c_str());
					printf("\ndir now in= %s",stringc(m_FS->getWorkingDirectory()).c_str());
				}

this code is path of IEventReceiver, that the file of scene is open from FileOpenDialog. I confused that where the code of changeWorkingDirectory have placed.
Please help me, maybe all of u have a sample code like my mean..
Sorry for my english, i wish u know.

you should post what is the problem - is there compiler error, what dir have you end up in?

I see two potential problems,

1 problem is in line
stringc m_WorkingDirectory = "C:\SPPK Rumah V1.4\sppk\sppk.";
cause escape character \ can act weird in that string. Change it to \\ or /

second, EGET_FILE_SELECTED is event called after you pick your scene! so you are already in the wrong dir (not the root one)
go to the code where you call the FileOpenDialog to appear, there, before calling dialog, store your working dir:

stringc m_WorkingDirectory = m_FS->getWorkingDirectory();

then in eget file selected event write

m_FS->changeWorkingDirectoryTo(m_WorkingDirectory.c_str());

BEFORE loading your scene

I had probles with that too

Plus you shouldn't ever set a path like C:/blah/blah because that relies on a specific driver and directory structure which you will not have control over on a user's PC if you decide to release your app so you should only do this if you're using the app only your PC for its entire life, and even then it's bad practice.
