I’m completely new to Blueprints and I’m starting to play with it now. I have used Fusion(Clickteam) for years. It has limitations, the biggest one being that its 2d, but its very good for making you strong at figuring out how to bring about events by creating unique conditions. You might want to download the demo and see if you can get the logistics down using that, then figure out how to execute the logistics in BluePrints.
