worst part about taking breaks from unreal is knowing everything you need to finish a system, but forgetting all the specifics and having to follow toturials for a few days xD
Oh yeah, definetly lmao, that's been my situation in the past few days. Thankfully i have a bunch of old notes on my phone regarding what to do next in UE... but i take a lot of notes, so digging those up will be an enormous pain -_-
I thought I knew blueprint interfaces, but you blew my mind by calling out how adding details on the outputs changes how it's called. This is a real game changer for efficiency in what I'm working on, great video!
This is awesome. I'm not sure if you have something like this, but an in depth tutorial going over blueprint communication in general and the different methods would be a solid hit. There's no obvious tutorial out there that I've found.
@@Beardgames Dope! I got my associates in Game Design and I feel like they really didn't go far enough in depth with blueprint communication. I think a lot of beginners would really benefit from a detailed explanation and would stick their projects out!
@@21GunGaming Hey that's awesome dude! but yeah I hear ya, blueprint communication is a massive tasks so as much knowledge as possible is needed. I'll see what I can do!
I'm really confused. I am trying to have a pushable blueprint with a box collider tell my Interaction Component that the player is overlapping. I can't have Inputs and Outputs with the same variable name on a Function in my Interface, so I can only set or get in the respective blueprints. How do I pass this information between the two? It's just a simple "canPush?" boolean. Nobody seems to explain this in a way I can understand.
Can I call individual variables from one blueprint to another using interface? For ex, I'm having some skeletal meshes inside my character bp. I want them to be called into another blueprint without using casting. Can interface do it? And if yes how?
So I'm still a little lost. I tried this (instead of a boxcollision I just used a keyboard input for the example) and it's not coming up. What I'm hoping this all allows for is a way to say trigger "things to happen" like the resetting of a boolean or a random location generator without Casting. is that what this is supposed to help with?
This is a very helpful tutorial. I wish I had this earlier. I hope new developers watch this video and learn how to use interfaces instead of lvl bps or casting all the time.
I've lost count how many tutorials I've watched about this and still can't get it to work. The first issue I have is that I can't even get a reference to to the correct blueprint as you do at 3:35, I only have the top option (the BP interface itself) and not the BP I've added the function to. I've compiled everything and added the function to both the blueprints. Does anyone have any idea why it wont work?
maybe late and maybe not helpful but when you clock and drag a node off and get the pop up box of all the new nodes you can pick, you'll see a box that can be ticked on and off in the top right that says something about only showing nodes that make sense in context or something like that. If you untick this box you will be able to see all the nodes available instead of just some, it's possible you will be able to find it now but keep in mind now you can see every node so you may need to search around a bit harder but I needed to do this to show the interface that specifically said "(message)". I personally could not get this to work for me still but this should help others hopefully.
@@sezpul8325 haha, thanks for the reply, I've come so far since this post.. hopefully it helps someone else :) Also interfaces are only useful in certain situations, so if you can't get it to work, there are easier ways
It took me SO LONG to figure out how to use Interfaces. Now that I figured it out, it's so much easier. I don't know why interfaces seem so complicated, but they are really not once you understand them.
Whao... interfaces are weird in blueprints. I was trying to save a reference to my class which implements the interface, but that wouldn't work. Meanwhile you can just call any interface method from any object and it'll work if it's implemented. Weird.
this is the best tutorial on interfaces that I've wateched so far that really made me understand when and why we would use an interface bp. so far I've been looking at ll these other tuts and at the end of the vid I'd still scratch my head still thinking "and still , how tf do I use them/for waht reason" this one is so clear and nice. Great work mate. Subbed
Damn Denarus thanks so much for the kind words and I'm really glad I could help you out! Keep smashing it for us and keep me posted with how you're getting on :)
Overly complex,. and stupidly convoluted. I hated the 2004 editor and every iteration since. Horrible to work with, plus, nodes make NO sense to me whatsoever. All I wanted to understand was how easy it'd be to make a teleporter rise and drop out of the ground (a glass floor) as the player approached it / stepped away from it. I don't have the latest editor installed, it was just that a friend is porting my UT99 W007 map to UE4 (5) and she's not prepared to keep the functions I built in place in my original; I figured I'd find out how easy (or hard) it'd be to do it myself, despite having a passionate hatred of the new editor.
I tried to go further of your tutorial, meaning, i tried to implement a function in a BluePrint Interface (meaning passing varaibles with inputs/outputs).. I could not see the benefit of it. Mainly because you have to input the aimed actor. If you dont have it, you will have to cast it so function become useless. But I mean i discovered interface with your video and it changed my coding life lol. So if i am wrong and BPI functions are really powerfull, dont hesitate to do a little video about it, it will serve!! Thanks again for this supergood tuto !
hey man I was wondering how would I use a blueprint interface to avoid the cast node in the anim blueprint for my character? I think that that initial cast node is tanking my framerate.@@Beardgames
Maaate! Thank you so much! I cannot get one Interface to work well on a AIController... the same one works just fine on another actor... Any hint? Cheers!
I think you answered the first one while I was editing... (sorry, and again: Thank you!) I cannot get one Interface to work well on a AIController... the same one works just fine on another actor... Any hint? Cheers!
@@FB-eq9vl Course! Anything you want to be passed over as a reference just add it as an input, then you can send it over and then convert it to a variable on the recieving end :) for UI what I like to do is handle all the UI in the player controller then create receive events in it so I can pass over that UI to any BP in my project by getting the player controller and calling the receive event! We'll make a god developer of you yet FB73😎

Get player character at 5:46 wouldn’t work in multiplayer though right; How would you interface with multiple players?

amazing explanation and awesome examples! i really love how you show the examples. Thank you\
works this also with an click Event on a ui button? in my case the print string doesnt fired up!

Can someone tell me why the target input pin on my call interface node is a float? I can't use it because I need to plug in my actor. Thanks
I like your tutorial, but if I may ask a question, if I have a blueprint with an output, would I be able to conduct logic through it?
