How To Interact In Unreal Engine 5 | How To Use Blueprint Interfaces In Unreal Engine 5 (Tutorial)

Hey guys, in today's video I'm going to be showing you how to create and use a blueprint interface. In this example, I will be creating one to interact with different blueprints as my player character.

I interact with unreal engine 5 by yelling at the monitor and then watch one of the many tutorial videos by Matt and then say oh I have to click on that. And it works perfectly

[feomec]

I already watched a lot of other videos from other sources trying to explain BP interfaces. You made it so easy to understand in this one, thank you so much.

Seriously, this way of using blueprints have opened up so many more doors for me than the door in this tutorial, whenever i felt stuck how to solve something, this method have often worked so well

[chetleahey]

Love you man. Your tutorials are perfect. They explain things in a way that helps me understand the broader concepts you’re using, not just in that specific way of implementing something.

I'm new to Unreal and am working on a VR game and was looking high and low on how I could use the motion controllers to interact with objects. Thank you so much for this video; I think this is it!

I love this pattern but I think the proper way to set up input actions now in 5.3+ is the input action and input action context. Other than that this still holds up.

Key to all interactions in scene - fantastic tutorial, big thanks !!!

Interfaces function works well with sphere trace or line trace by channel ;)

For anyone that wants the button to close the door on a second press, you can just add the "Flip Flop" node to the door_BP. Place the node between the "Open Door" custom event and the "OpenDoor_T" timeline. Just plug A into "play" on the timeline node and B into "Reverse" on the timeline node. Hope this helps!

You're brilliant. Thank you for explaining this in the best way possible! Came here right after the prompt on object video. My teacher sadly presents this in a much more complicated way, as do other YouTubers I've found. So, THANK YOU! And Yes, I've subscribed obviously ^^

I always name the blueprint interfaces as BPI_functionname. Generally I'd use it more similar to modular functions which could attach to specific actors that would use them. It's super useful and I have many blueprint interfaces in one project. I know that I can make many functions with just one interface, but it wouldn't make any sense when you're putting the damage system and the interact system at the same thing since not everything would use damage system and it's better to make them modular than trying to fit in a bunch of them together.

Super Helpful. 🙏
Had no clue Interfaces were so clutch.

Hey, Matt! Great tutorial! Will you make one about the new Input Commands of UE 5.1? The Axis and Action Mappings have been deprecated and I do not know how to add input anymore.

[Bramski]

Thanks, I was struggling to understand the way, why and how the blueprint interfaces are used. Thanks for the great tutorial : )

[Star_Jewel_Realm]

Good tutorial. However we need some updating. UE 5.2x had an important message for Input. We should use Enhanced Input Actions and Input Mapping Context. See UE 5 docs for details. 🤔

[dreamingacacia]

I'd love to see you explain more about function blueprint(the one that purpose is to have a bunch of functions) and using game state. Right not if I'm not using the default game state, the characters cannot move at all(using thrid person template). OR alternatively something that helps me taking the variables that will affecting the entire game. I could try to save them to the player controller but in a more advance scenarios I'd need something higher than player controller which persisting throughout the game and not limited to the scene. Though I can just use level streaming and save everything on the master level's bp

Great video Matt! Could you make a tutorial on physical hit response? That would be a huge help! I appreciate it!

[Marvoldo]

Much better than cast all the time, thx for the tutorial <3

[DPW]

THANK YOU!!! I swear this is exactly what I was looking for and couldnt figure out <3
