[@masterx_6119]

bro you have all tutorials i need for making a horror game. that helps me a lot. thanks a lot

[@PatrickTheDM]

It's a variable key to success! 😁 Edit: As you can see from my comment I expected you to use variables to match the key and door and you surprised me with a new way to do it. Great tutorial. Now I understand why you did a tutorial that you had done in the past.

[@exakelgaming]

this helped with one of my game design assignments.

[@jawsomeproductions]

This was a great help, thanks for putting it together!

[@GrownAssNerd]

Thank you for this easy to follow tutorial! Keep them coming!

[@vickycorbalan8556]

your tutorial was great! thank you so much :)

[@bunnygodx]

great tutorial, thank you!!!

[@One-4-uDe]

Awesome, that way is more elegant as I did with variables.

[@lordhightower6124]

very nice man thank you

[@ravi12880]

Thank you sir i appreciate it 😊

[@Lucifer100990]

Thank you

[@AUTONOMOUSTANZIM]

Ur the best tutor ever

[@muneebhero1159]

Please matt as planned I am begging you please please please make a video on unreal engine 5 first person shooter combat system please

[@vladiktomil434]

Very good tutorial bro! Thank you so much. Let's see you could upload something with Advanced Locomotion System.

[@kevCarrico]

great tutorial - i'm using this to put a coin in a subway turnstile (and then setting "has key?" to be false) - thank you!

[@topcheckers_]

When second part to multiplayer doors, please we need to this, with linetrace without box overlapping

[@studiodenne]

Hi, thanks for this tutorial. It still works when I put the key anywhere on the map. But if I put the Key inside an drawer, as an child actor, I can pick the key up, but can´t open the door, because at this moment I can´t promote the BP_key to the BP_door at the default. What can I do to put Key inside the drawer an use them ? thank you

[@makarqvvv]

you best

[@CountCoffee]

I did your UE4 locked door tutorial and it didn’t work… I hope this one does! Lucky I didn’t do this more than 3 days ago XD

[@raulalvarado7465]

I just used the aitudthy heavy key repond.

[@andrewvanderwalt8494]

Hi Matt, Awesome tutorial mate! Question though...How Can I make it that the key can just unlock a door when picked up without having to select it with the picker when spawned into the map? In the class defaults it is grayed out so I can't set what key will unlock which door before it is spawned into the world. I want a boss AI to drop the key and the player just picks it up and unlocks the door that was set for that key. Thank you in advance

[@Buddyer_ler]

hi i would like to know how to make a submarine for a game, if i can

[@jawsomeproductions]

Is it possible for one key to be set for multiple doors, like a key card system?

[@ERAK_Aenyegames]

I have one question, my door just do ROTATION, bot not open like urs, how it can be possible ?

[@GuestStudios690]

hey bro i got a problem in my game: i want to make it so when a object interacts with another object one simulates physics but i dont know how to do that

[@CyberianWaste]

How can this be adapted to open multiple doors (the blue keycard opens all blue doors)? Would you have BP_Key contain an array of multiple BP_Doors? Or is there a more efficient way?

[@MonkeyDGhoul]

did you manage to do it? and how? thanks

[@andresaraya5198]

idk if this will actually work but, can you add a int to specific key and then assign the same int to all the doors you want to open with that key. When trying to open them you can check/compare if they have the same int, if that is the case then the door opens.

[@itsnotmeitsyou7615]

You can use gameplay tags.

[@Mikaela112]

For some reason the doors collision is gone and I can walk through it? An idea what's caused this?

[@giloniellfeliciano6911]

I tried doing it exactly but the only thing it doesn't let me is interact with the key, pressing the key on my keyboard doesn't activate

[@makarqvvv]

I love u

[@ahmadruslanovich739]

Hi, Matt! How would you make a smartphone like in gta v? I mean there should be user widget and what’s happening on that widget should be displayed on phone object model. How we can transfer my user widget state into phone model widget? Anyway thank you!

[@ahmadruslanovich739]

Nvm, figured out

[@SharinganDeeOfficial]

What do I do if I want my door to require more then one key

[@shinykyogre7197]

the key wont be picked up, so odd

[@JasperDoggo]

for some reason when I open the door I can't go trough it. Anyone know a way to fix that?

[@goldskull4498]

soo confused, i followed step by step and it still doesnt work. i think it might be the timeline thing idk how to use it ugh

[@Ihatepe50]

everything seems the same however i cant get the pick up key to trigger in the door BP i can pick it up but it doesnt set the locked bool to false

[@Ihatepe50]

nevermind i figured it out i skipped over the 5 seconds thats showed me i just needed to set the door on the details panel of the key

[@m23rco]

Bro everything with key work but the door dont move, pls

[@Kami-fs2db]

interact doesnt show at 5:00

[@Tamrielforever]

The key wont pick up for me. The only difference is I had E already set up. I've set up a door before. Just not with a lock system. Any tips?

[@Tamrielforever]

UPDATE. The last part where i connect the door to the key isn't working!!

[@amarshil2415]

Hi mate can you make a Vedio on how to make jump attack system

[@OnlyViKnows]

So the tutorial worked sort of? Except it made my door does a complete 360 rotation even though i followed everything

[@Tamrielforever]

I tried this on a new project and the key still wont pick up!!! There might be something you need to update.

[@MattC-137]

How can I open multiple different doors with one key?

[@MattC-137]

I figured it out: if you right click on the door variable within the key blueprint to then change variable type, it will change it to an array and allow you to assign the same key to multiple doors.

[@Salad-Gamer]

8:31

[@JoTheMonkey]

last part doesnt work for me

[@JoTheMonkey]

for some reason the door wont be accepted as an actor or something

[@george_iv_4548]

My door opened up and down 😂 I don’t know what I messed up

[@NotSnakeRex]

try rotating it not on the Z Axis, try the X or Y Axis

[@itsnotmeitsyou7615]

Do not suffix bools with question marks, and don't put spaces in variable or function names. These are bad practices.
