Thanks so much for this nice Plugin. I hope this will get an official, non experimental some day since it has to much potential for classic unreal AI development.

Hello! I ran into an issue on the course, the blueprints are not rendered fully. When I try to copy them with the ‘Copy full snippet’ button, only rendered part gets copied, which is about 20% of the full blueprint. Tried in multiple browsers on multiple devices, same issue everywhere. Also applies for the 5.3 and 5.4 version of the course. Any idea what to do?

Hi, I am having the same issue as well with the blueprint references in the documentation not rendering properly / missing most of the nodes.

Looking into this. Thanks for reporting!

I have the same issue in the “Design a Puzzle Adventure” tutorial, on the “Project Setup and Level Blockout” page. Trying to copy the blockout using the “Copy full snippet” buttons only copies the first 16k of text, whether or not the snippet is expanded. The problem occurs in several different browsers.

Thanks for your patience! This has been fixed.

Thank you for this plugin. It helped me a lot to understand the basics of RL. I documented my findings in my blog. You can find the last one here. Let me know if you think there is something wrong or missing.

@Deathcalibur I love this tutorial thank you for making it.

I believe in 5.7.4 the part in regards to imitation learning I believe is broken. The “Make Imitation Trainer” now has a new input “Communicator”. I’m not sure how to use it properly and I don’t know if it needs new settings, it’s some kind of a struct.

Any advice would be great, as that part of the entire course is the most relevant for me :slight_smile: . Anyway thanks again, hope to see a reply.

I had to change it like this, you can see the commented out parts from 5.5.

// TrainerProcess = MakeUnique(
//  ULearningAgentsCommunicatorLibrary::SpawnSharedMemoryTrainingProcess(TrainerConfig->TrainerProcessSettings));
// Communicator = MakeUnique(
//  ULearningAgentsCommunicatorLibrary::MakeSharedMemoryCommunicator(*TrainerProcess));
FLearningAgentsSharedMemoryCommunicatorSettings CommSettings;

TrainerProcess = ULearningAgentsCommunicatorLibrary::SpawnSharedMemoryTrainingProcess(
TrainerConfig->TrainerProcessSettings);

Communicator = ULearningAgentsCommunicatorLibrary::MakeSharedMemoryCommunicator(
TrainerProcess, TrainerConfig->TrainerProcessSettings, CommSettings);

PPOTrainer = ULearningAgentsPPOTrainer::MakePPOTrainer(
LearningAgentsManager,
Interactor,
TrainingEnv,
Policy,
Critic,
Communicator,
ULearningAgentsPPOTrainer::StaticClass(),
TEXT(“PPOTrainer”));

Looks like the 5.7 overwrites snapshots when saving. The previous one (5.5) saved them nicely with step count labels. Does anyone know if there is a way to enable it in code? I couldn’t find anything in TrainingConfig.
