Right now, the blueprint folder is pretty hidden. Try make it more simple, e.g. read the Windows download folder, or allow to write in other places.

@SpaceToad computercraft alows you to put programs in resourspacks so it should be possible (don't know exactly how)

I can look in to it if there's enough interest

I believe it's just as simple as searching for files using a ResourceLocation and the supplied InputStream

@dmillerw let's go for ./minecraft/blueprints then. It be useful indeed to have a default location for resource packs too.

Windows download folder

But please don't forget about other OS.

Not really sure the download folder is best. It should stay within the .minecraft directory, as that's where everything Minecraft related is.

Could have a button (blueprint library?) to open up the blueprint directory though? Similar to the resource pack location button.

maybe make it so that the blueprints can also be included in resourcepacks?

@Prototik I don't know other defaults, but I'm happy to add a list if of download folders if you know about them. On windows, that would be something like:

System.getProperty("user.home")+File.separator+"Downloads"

@dmillerw I'm not sure either which best output would be. Right now, it's .minecraft/config/buildcraft/blueprints/client. Maybe .minecraft/blueprints?

@AEnterprise how would you include a blueprint in the resourcepack?

@SpaceToad .minecraft/blueprints would fit the standards the best. As long as it's descriptive, I don't think it's an issue. You could even be safe and do .minecraft/buildcraft/blueprints

Done this initial check-in. Feel free to complete the list of default input directory to support other OSs. @dmillerw, the road is open to implement support for resource packs on top of this ;-)
