How to communicate between Blueprints (button and Door)

How to set up two blueprints that will interact with each other in Unreal 4

[@iceddz]

You're the man. Thank you for making this as SIMPLE as possible. This took me days to find an answer to. So many other tutorials over complicate things and don't just simple link the two blueprints the way you did. Now I can finally make the "switch" downstairs unlock the door upstairs... Or have my character pickup a key and have it be usable on a door (or many different doors) throughout the level. Seems like a very simple thing to be able to do, but nobody else I could find was showing how to do it with TWO separate blueprints. Can't thank you enough!!

I LOVE YOU!!!!!!!! THANK YOU SOOO MUCH I WAS SEARCHING FOR THIS TUTORIAL FOR A WEEK!!!!

[@theillusionlotus1491]

dude this had me eating away at my brain for so long. trying to activate a animation in a seperate zone but could never figure out how to link the two. thank you

[@martinamateo4296]

so well explained, thanks so much

[@leonardobruni6887]

Finally, i was struggling on this, thanks a lot !

[@punishedproduct]

Brilliant! Searched everywhere!

[@avarionuk4283]

This is driving me insane, I am following this tutorial and its just not working for me. It says " 'Switch' Object reference is not compatible with 'Cone Move' Object reference" The 'Cone Move target has a box that says 'self'. Please help me its driving me nuts

[@spellwhisperrr]

tutorial starts at 3:50

[@barulicksama3838]

How do i reference more then 1 object?

[@fuzzypanda1684]

This! I'm wondering the same thing. *Edit, nevermind, he answered it below, you just have to make multiple public variables for each door.

[@terrablader]

No casting ? no interface? No event dispatcher? No get all actors of class? I am confused after all read none of it needed???...

You are the one and only person I've seen who has finally demonstrated how to activate something remotely, without walking up to it and activating up-close nor standing on platforms/trigger areas to make it move automatically (which is literally what all other videos show). I dont know why it had to be so hard to have found this video, but thanks for making it. Best of all, its far simpler than most things I've seen too!

[@andrew-martin]

This was just what I was looking for, thank you so much.

"Accessed None trying to read property " Can you fix this? I use UE4 4.22

I have the same problem - did you figure this out?

[@DuckJohnn]

How about multiple objects with same blueprint? I don't want to choose only one object.

[@Danha808]

did u ever figure this out

[@DatCameraMON]

Does this work for UI related stuff too? Cause I am unable to get it to work. All I get is: Blueprint Runtime Error: "Accessed None trying to read property (blah)"

[@HugSeal42]

This is just an amazingly great tutorial. 5years later and it's still incredibly useful :D

[@lisatapelefond7755]

BIG thank I finally found a simple and clear tutorial, thank's, i struggle with this since few days, and many tuto are bad

[@ShereefHisham]

Beautifully explained. Exactly what I needed. Thanks

[@shadowzero3673]

I cant reference Objects as a Variable Type could there be a problem with the software or am i using a different version?

[@hiQer]

Just type in the name of your custom Blueprint it will find it. Then reference that (blue).

[@patricksullivan4918]

I had this problem too, I was searching the custom event name, but found it when I searched the blueprint name

[@andym.347]

thanks so much. This is what i need in my game :)

thanks!

[@GraveyardBoogie]

Thank you for this! Was having a super hard time figuring this out and your video helped me get it working.

[@doublechindoge7]

Bruh. I was told all you had to do was make it public. Well, at least it was a simple solution.

[@WhiteTechWT]

Thank you so much! Really helped me! Was really struggling with this!

[@garozockt7198]

Why doesn't it the same way with UserInterfaces?

[@santiagoluib3]

Thank you for this video. Does the same exact blueprint logic apply to UE5 as well?

[@MegaBcoyle]

It should do yes

[@outtoplay]

Wow... an oldie but a goodie. Thanks for this.

[@kanysam8167]

Simple but nice and cool

[@rgbtryhardled636]

but how could you make the button open multiple doors, in the details panel there is only one slot for the blueprint to work with

[@MegaBcoyle]

Make multiple public variables for each door.

[@rgbtryhardled636]

@@MegaBcoyle Now that I know the answer it seems like it was a dumb question. Thank you.
