I am very new to UE. Just starting out. And I I would like to know if it’s very difficult to add an in game shop to buy upgrades for a players character, and if anyone knows of a good link for that.
There are plenty of tutorials about setting up inventory systems, which are basically “shops” you could check those out. It is unlikely you will find a tutorial that does exactly what you want for your particular shop but there are enough on YouTube that you can probably watch a few and figure it out.
