![]() Maybe in the future we'll look again at changing the internal format but for now protobuf it is. While I haven't tested this I would say something like FlatBuffers or Cap'n Proto might be an even better fit than protobuf, but they just don't have the supporting community, documentation, and environments that protobuf has.ĭocs and community trump features and performance every time. many different programming environments supported.supports collection based data structuresĪnd had a whole bunch of other benefits that are tricky to achieve already done for us:.We could have created our own format but that just invites problems, so we chose to move the internal format to protobuf because it matched our requirements: Under the hood then, Yarn dialogue is nothing but a big list of instructions that Yarn Spinner obeys, some of these instructions show lines to the user, others are responsible for features like reading variables or branching your story.Īll of this means that keeping Yarn as text at runtime isn't the best move and we needed a binary format. csv file) to work out what to show to the user. These line identifiers are then looked up in a strings table (a. While Yarn scripts are text you really don't want to be parsing through a giant blob of text every time you need the dialogue, we want something a bit more lightweight.Īdditionally with the improvements to the localisation support in Yarn Spinner the core of the project no longer even cares about the dialogue itself, all it sees are line identifiers. This might seem a little weird as Yarn is clearly a text format: you definitely write it as text. ⚠️ This was written for Unreal Engine 4.24.3 using Visual Studio 15.9.21: It may not work for any other versions! For Those That Came In LateĪ little bit of backstory, Yarn Spinner uses Google's protocol buffers (also known as protobuf) as its internal storage format. If you don't care about the story that led to this blog and are just after the example code please go to Github repo. This is because it is as much for me to process my thoughts and have a record of my thinking for later on when I forget it all, as it is for others to learn from. Please note, this is a fairly dense blog post. ![]() This is a story of integrating protobuf into UE4. I didn't think porting Yarn Spinner would be easy, but I also didn't anticipate the hardest part (so far) would be reading the yarn files into Unreal. While that task isn't finished, the first stage is and this is the opportune moment to write a blog post about the challenges thus far. * \Program Files (x86)\Microsoft Visual Studio _.A little while ago I embarked on the adventure of porting Yarn Spinner to Unreal Engine.
