Hey all,
Hopefully just a few pointers and links from what I learnt yesterday whilst trying to package and export a test build, as I encountered a few pit falls and didn't want anyone missing the deadline after creating a project and then not being able to release it!
First check out Matt's guide here
Then, if this is your first foray, your computer will probably need to install some C++ dependences, this is so Unreal can encode your Blueprints into the code that Windows needs to run the game. Follow this link to install Visual Studio by Microsoft.
https://visualstudio.microsoft.com/vs/features/cplusplus/
Click Download Visual Studio with C++ and in the dropdown you can select Community 2022, install that and restart your machine.
Unless you plan to code for Unreal using Visual Studio, these steps should have your system setup correctly as is to package and export your project for Windows.
In terms of the output log in the event of a failure (of which yesterday I had a few!) Anything in red will cause a fail. I had some inventory code that failed due to a strut type being unrecognized, turns out the blueprint code was ok, and it was an old, on again, off again bug Unreal has had for ever. In my case the Unreal error code was :Unknown, cheers guys! So I instead googled the node in question, and turns out just deleting and then re-adding the node to the effected blueprints fixed it!? Anyways, my point is to not get flustered, take each red line one at a time and work the problem through google, search and sort. All part of the game I guess!
Hope this helps eliminate any last minute stress!
Looking forward to what you have created :)
