Hi!
I’m using Unreal 5.4.4. to package a demo in shipping configuration. This is the first time I do this and I’m a bit loss.
The game uses some text and binary files which are non-assets. To include them into the game packaged, I have added their folder to the Additional Non-Asset Directories to Copy list, but the files can be copied and modified because they are just copied to the shipping folder with the same structure than in the game.
Is there a way to hide them?
I have also tried Additional Non-Asset Directories to Package, but if I use it, the game can’t find the files.
Thank you!
Additional Non-Asset Directories to Package should add your non-assets files to the PAK.
First, make sure they are in. Use UnrealPak to dump PAK contents after packaging. UnrealPak used to be shipped with engine but I’m not sure anymore nowadays, might have to find one online or from a previous version.
If assets are in, you have to open them using the IPlatformFile API (which should be an instance of IPlatformFilePak in shipping). You can get it with FPlatformFileManager::Get().GetPlatformFile(). Utilities from FFileHelper already use it under the hood so if you are using them you don’t need to change anything. However your standard C++ file system APIs will not work.
Lastly, to access PAKed files you’ll have to use virtual file paths, not disk paths, so if your file is in Content/CustomFiles/foo.txt then the path would be like /Game/CustomFiles/foo.txt.
