[iOS] Load Textures/Images outside of WorkingDirectory

[IrrlichtForiOS]

Hi Guys,

developing a new Irrlicht based App, we need to load an image as a Background texture, which is placed in an other directory as the irrlichtDevice's workingDirectory.

Is it possible to switch the workingDirectory to load this images, or is it possible to access directories outside of the workingDirectory?

Example:
- App Sandbox
------ Documents
----------- background.png
------ App-Data
----------- media (the working Directory)
----------------- all other textures

Regards,

Daniel

It's possible. You can do something like that:

Code: Select all

core::stringc filePath = [[[NSBundle mainBundle] resourcePath] UTF8String];
filePath += "/Documents/background.png";

or something like that (if you don't want to use objc):

Code: Select all

path filePath = irrDevice->getFileSystem()->getWorkingDirectory(); // AFAIK at default working dir is set to resources path, but I may be wrong
filePath += "../Documents/background.png";

Thanks Nadro! We just found out, that it's possible to switch the directory while runtime.

Code: Select all

stringc workingDir = device->getFileSystem()->getWorkingDirectory();
            
            device->getFileSystem()->changeWorkingDirectoryTo(FAAppFrame::getFassadenBilderDirectory());
            
            //LOAD IMAGE FOR BACKGROUND
            loadImage = new E3DCLoadImage(device, smgr);
            loadImage->loadImageForBackground(FAAppFrame::getCurrentFassadenBildName());
            
            device->getFileSystem()->changeWorkingDirectoryTo(workingDir);
