I did this course a couple of months ago. Highly recommendable. On special every other day for ~$15.

Very glad I did. It would've beeen torture to try to learn and troubleshoot this stuff via YouTube walkthroughs alone.

Yeah never pay full price for anything on Udemy. I got that same course for like $10. It was pretty good.

The GameDevTV multiplayer course was also quite good, probably better actually. Covered stuff like lag compensation and client side prediction etc. See here if interested.

This one might be better https://www.udemy.com/course/unrealmultiplayer/ I did both this and the course by tom looman, and I liked this one a lot more. I felt like they didn't explain some stuff properly but it's still good

Blueprint should also be used for final projects as well there's so much thing you can do to make development easier while crucial parts in C++ such as Ability System and Multiplayer/Networking.

I use Blueprint for basics mechanic part of my video-game anything that requires me to move characters, animation montages, User Interface, Basic Replication, and Health/Armor/Stamina/Mana Bars especially when you give specific numbers for say your HP or enemy HP including speed or mana for something like spells or special abilities.

I hate this guy's work and I will NOT endorse him other than this one particular lesson he did for Udemy. The reason why I recommend this is because he covered some good info on replication, but as far as the other courses he made I will not be endorsing it. If you want a more professional approach with clear details get those two courses to get into multiplayer / networking for Unreal.

(Only take this course to get a better idea on replication. As far as doing the other stuff such as making maps just flat out ignore 50% of the course as it's useless information.)

When you are familiar with Replication do get into the advance topic of Multiplayer as it's very important to get into. Yes! Replication is Multiplayer it's just that knowing to understand what needs to be replicated and how to replicate things is what you need to focus on as a beginner.

As metalcat said, this stuff gets outdated really quickly but this should get you going.

I've personally completed Tom Loomans course: https://www.udemy.com/course/unrealengine-cpp/
but the project has not been updated in some time. The other highly rated course that I've started on is: https://www.udemy.com/course/unrealmultiplayer/ and has been updated recently.

Along with the recommendation already made (the Network Compendium that's been linked already really helped me get to grips with the fundamentals) I can also recommend the following course on UDemy.

https://www.udemy.com/course/unrealmultiplayer/

It's a really thorough course and is frequently on sale for £9.99.

For free tutorials on Youtube, there are also the following (though I haven't been through these ones yet...)
