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
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.
I 100% agree. I'd watched 3 videos on blueprint interfaces before yours but yours is the only one that finally made me understand what they're all about. Clear and straight to the point, you're a really good teacher man!
I'm new to UE5 and have been dreading trying to learn yet another programming language on top of getting used to yet another game engine, but this just seems so simple, yet so powerful. Maybe I don't need to fret so much! Thanks for the clear and straightforward explanation. You have a new subscriber!
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!
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
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 RUclipsrs I've found. So, THANK YOU! And Yes, I've subscribed obviously ^^
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.
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
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.
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.
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!
Just an update for anyone doing this in a later version of the engine... the Overlap actors doesn't work with a reference to Self anymore, so put your player capsule in the target.
I am finding that after opening the door, the closing/reopening is often not as responsive. Any ideas how to fix this? Feel like I copied the video exactly.
do you guys know why when im in my door_bp trying to add the implemented interface, the interface doesn´t appear at the left (in the "my blueprint" section) so i can´t display the event interact bp?
I just want to access a bool variable in blueprint-1 from blueprint-2. Why is this so hard? Do I really have to do this with interfaces, is there no way to make a "get" in BP-2 to get the bool from BP-1?
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. 🤔
Can you explain how to transfer information across blueprints via interface? As soon as i try to add an output pin. I cant implement it as an event. It will show up as a function with in/out execution pins
Great video. Really well explained. My only humble suggestion would be to try not to run your words together, as it can make some of the things you say difficult to understand. Thanks for the great content.
Was following along well until the door stuff. My door timeline doesn't have a 'door track' and the "set relative rotation" only has a single entry for XYZ rotations. Is it supposed to be a different type of actor?
Door Track shows up after you add a float track to the timeline. And for the XYZ rotations, simply right click that knob and select "Split pins" It'll separate them into X, Y and Z
Hello Matt Aspland. Thanks a lot for the tutorials. They have been very helpful. I would like to ask you how I use the "crosshair" from the tutorial you made using blueprint interface along with an interaction like opening doors, turning on lights or even changing materials in a mesh. again thank you very much
First off, love your videos, they have helped me a ton with my project. This one in particular. However, I've found a bit of a problem with it. There's no way (at least that I have found) to turn this off. Once you overlap, it fires off the interact and makes it an almost permanent state. This has lead to some issues with interactable objects I've set up where it continues to fire off the functions I've written even after I've stepped away from them. Any help would be appreciated!
I'm thinking of making a scene component that can be added to any blueprints with Collision component and functions that fire off upon the player entering the field. This way, I won't have to keep applying the same code into every actor. Is this recommended?
Great and short tutorial mate, thank you so much! Unfortunately my interface just doesn't trigger… any idea why that could be? I might be on a newer engine version than you but not sure
6:09 are you not supposed to hook up the false to the break as well? will it not continuously loop if you try on an actor that does not implement the interface?
If you hook up the false as well, it will end the loop as soon as one is false, which if that is before the true one - it will never reach true. The reason why it doesn’t continually loop is because as soon as it has gone through all the elements, the loop will end, instead of going back to the beginning of the array. I get you’re thinking though. Hope that makes sense!
When double clicking the interact thing I go to a new thing instead of just spawning a event (UE5.1) and aswell I get sent to a new function where I cant use certain BP nodes EDIT: Never mind outputs caused that but outputs to me are useless
This is fantastic man, thank you so much Edit : Just tried it, came back to say, this has absolutely changed everything for me. i am so very grateful dude. tysm Edit Edit : could this method be used for like a global music manager? so a variety of songs play when adventuring, but if a player enters a town, or combat per se, the music fades in and changes, until combat is over or they leave the town and the adventuring music starts again? :)
Check out how metasounds works! I just barely use them for playing a bunch of sounds together, but from what I've seen the new sound system has been made with this kind of interaction in mind. It works like a blueprint but with sounds and in a "event flow" flavour, meaning that you have more control on what fires off the sounds and how to transition from one to another
Hii im trying to add a key system on top of this but when i try to connect the branch node or the set key variable node to the interface it does not work and always shows an error. can anyone help
Awesome. Im making a building game where I want a menu list of items to pop up when you press a key… then when the player selects an item it spawns into the world. Any suggestions?
Great tutorial! Can you make one where you show how to make a widget minigame like the ones from the circus baby repair Fnaf the glitched attraction. Appreciate it.
At time 6.40 i attempted to set up the event graph as im a complete novice. I typed in door timeline but it does not compute when i typed it. This part of the video im currently struggling with. Does the door timeline have a particular name ?
Hey, Don't know if you resolved your issue, but the Door Timeline is just a "Timeline" node that he custom named. If you right-click in the Event Graph and type "timeline", you'll see "Add Timeline". After that, he set up his own timeline track to animate the door swinging. The timeline track is his "Door Track" output that he is connecting into the "Lerp - Alpha". Hope this helps!
I really wish I could find someone explaining how to interact with something you are looking at, everyone is doing by collision, and it's not what I want... It's so frustrating...
having some issues, My blueprints and interface look exactly like in the tutorial but after firing interact once, it will not fire again. Are there changes to the timeline I must implement?
Thanks for the feedback, I’ll keep that in mind for future videos! In the meantime, you can take a look at this video for opening and closing a door. If you want any additional help feel free to ask in my Discord server :) ruclips.net/video/dkeVrlRFJDk/видео.html
For me i did a REALY simple thing just to print hello And still no communication ??? I have done if CTRL is started Then send message, Then in ANimBP i send the message to print hello. There is simple no communication ?? wat am i doing wrong ?
hello, i don't know if you gonna read this message but is it possible to interact with an actor without using a box collision ? i don't know how to do it if its possible. Because box collision is a bit frustrating if we put many objects at the same place it will trigger them all at the same time.

Use a line trace and check if the actor hit implements the interface, if it does call the interface funtion/event
In UE5.1 the Add button has disappeared from Implemented Interfaces...
You now need to use the one underneath it called “inherited interfaces” instead
