Creating ArchiveLoader for custom Archive Format?

[Zecchan]

First of all, I read this in the API:

cpp Code: Select all

If you want the Irrlicht Engine be able to load archives of currently unsupported file formats (e.g .wad), then implement this and add your new Archive loader with IFileSystem::addArchiveLoader() to the engine.

Then, I'm planning to create my own format (for security reason).
As the above statement said, I look up for the IFileSystem::addArchiveLoader()
But I find the API is confusing
Can someone give me a tutorial or example on how to do this?

btw, I use IrrDelphi, but I don't think it is a problem is it?

PS: I don't want to use zip

See for example CWADReader.cpp and CWADReader.h in the source.

Umm... I prefer pascal, but, I'll check it, thanks >_<

I am afraid that Irrlicht functionality isn't exposed to Pascal compilers

Anyway, A custom format is relatively easy to create, All you have to do is to create a class that meets the requeriments of the interface, that way, Irrlicht will handle your files like all other it loads.

This is the interface.

Make it so you create an animated mesh out of your information. The good thing is that you wouldn't have to handle ZIP files on your own, if there was a file of your format inside a ZIP file, Irrlicht could handle it also.

Good luck!

Maybe encrypted zip files would already be enough for your purpose? That's available automatically in Irrlicht, so you wouldn't have to implement such things on your own.

Yes, he also wrote that he does not want to use zip. But maybe encrypted zip is good enough for security reasons.
