How do I save/load files from outside the p3d?

Scripting Issues
1

Hi there,
I already searched the forums but the only way i could find was with the use of start_dir but i want to save/load files into the same dir as the p3d so that the normal user can easily backup his saves
I would like to store some ini files there as well so that you can change game options as long as i haven’t implemented option dialogs.

Is this even possible or do i have to change to py2exe?

If you pass -c “keep_user_env=1” to packp3d, then the resulting p3d file will run in the current working directory, instead of in start_dir.

There is not, at the moment, an easy way to query where the p3d file was loaded from, though this has been requested.

Hmm…
I tryed it but it seems the cwd is the start_dir anyway.

The following code:

        plini = Filename(os.path.join(os.getcwd(),'players.ini')).toOsSpecific() 
        print plini
        print Filename(plini).exists()

will prompt this:

Hmm, it works for me. Can you use multify to examine the p3d_info.xml file within your p3d to ensure it contains keep_user_env?

How are you invoking the p3d file in this case?

p3d_info.xml:

<?xml version="1.0" encoding="utf-8" ?>
<package name="folks" platform="win32" version="0.0" main_module="main">
    <config display_name="Folks PRE-Alpha" keep_user_env="1" />
    <requires name="fmod" version="cmu_1.7" host="http://runtime.panda3d.org/" />
    <requires name="audio" version="cmu_1.7" host="http://runtime.panda3d.org/" />
    <requires name="panda3d" version="cmu_1.7" host="http://runtime.panda3d.org/" />
    <host url="http://runtime.panda3d.org/" />
</package>

The .p3d file is started with the runtime (double-click from windows explorer)

If you double-click the p3d file from explorer, you don’t have a current working directory, so it has to use “start” anyway. You only have a current working directory if you launch the p3d file from the command line; and in that case, it preserves that working directory.

One option is to store the save and ini files in a standard directory, like “c:\mygame” or something along those lines.
