That’s OK. Just as a bit of info, C++ is the programming language that’s used to make games in Unreal although many people choose to use Blueprints. I don’t think your question will get much attention here because the C++ area really is focused on programming questions, not general issues. You might have more success in ‘Using UE4’. When you do post though, please try and include as much information as possible. There are so many things that can go wrong that ‘messed up’ doesn’t really give anyone enough information to help you. Try and describe what you were doing, what happened right before it went wrong and exactly what the problem is now (use screenshots if you can).
