Thank you so much for this tutorial! It was incredibly helpful for my project. I was able to implement the functionality correctly and move forward with my game development. Keep up the great work!

[@UnrealART]

glad you liked the video! happy to be of help 🥂🙏

[@Plannito]

thank you so much, with this tutorial i now can end my school project! Sorry for my english, but i really want to tell you that

[@UnrealART]

Glad I could help! what are you studying ?

[@hazemsy2797]

Great work thanks, 1 thing that is interisting was when u click "E" in the Box, the widget will be opend as much as u press it, and when u want to close it, u need to close it as many time as u open it. Just Note.

[@UnrealART]

yeah good idea , thanks for sharing ! 👌👌

[@D3ck4rd87]

I can't get the door to close once it's verticle, I am making a castle gate and I have my collision box verylong on the bottom so the collision box will still be detectable. Once the gate is lifted I can't get it to close

[@masankaurat1974]

You videos are really helpful and easy to follow, my question is while we download the door model which format is the exactly the same one? I clicked the obj but it wasn’t the same one, could you please help me about that?

[@UnrealART]

@@masankaurat1974 hey , thanks glad you like the videos, I always go with fbx. if they came in seperated parts, you can enable combine meshes in the import menu

[@masankaurat1974]

@ Thanks for advice, I was going to same but there was no fbx choice, in that point I am bit confused.

[@UnrealART]

@ you can use other formats as well, but you need to be aware of the scales and texture sets

[@mysticprophecyroblox]

Awesome video, I like the order you did things to show how each thing works

[@UnrealART]

Glad you liked it!

[@TheJMBon]

10:32 You NEVER want to call 'Remove all widgets'. If you have a HUD, this will remove your HUD as well. You want to ONLY remove the widget associated with the door. Also, you don't create the widget on E press. You create the widget in the door's OnBeginPlay event and when E is pressed, you simply show it. On E again, just hide it.Its far less overhead and improves performance.

[@UnrealART]

yeah that's correct, Thanks for the tips 🥂

[@sinsamuhamad]

so instead calling "Remove all widgets" what should i call?

[@nitram1923]

hi, thank you so much for the tutorial! It was extremely helpful! But after i closer the UI the cursor is still visible, how do i remove that?

[@UnrealART]

hello . you are welcome. I think I explained it in the video . you need a remove cursor function in the blueprints

[@nitram1923]

@@UnrealART hello again. I have another question: I had a crosshair on the screen but after exiting the UI the Crosshairs UI gets removed as well. After trying some selutions I wasn’t able to fix it, do you have an idea on how to fix it?

[@UnrealART]

the problem is that when we remove all widgets, it removes the crossair as well. you just need to remove the widget you made and not all of them. In my video I removed all widgets because I did not have anything else and it didn't matter

[@A.G.Arts2024]

Perfect and super functional! I wanted to thank you and at the same time ask you if my idea of using the same system using a keyboard input in order to give the password with letters to compose a word or an entire sentence, is it really possible in the end? This is simply to know if I understand the direction in which I am going to look, thanks in advance! By the way, I can apply the "Remove Parent" in the blueprint of the widget but not in that of the door (I can't find it in reference, am I missing something?)

[@UnrealART]

Glad you liked the video. yeah it's totally possible to use the keyboard instead. With a couple of small adjustments you can create that system

[@A.G.Arts2024]

@@UnrealART Thanks, so I will look in this way I've got some Ideas now thanks a lot for sharing yours!

THIS VIDEO helped me a LOT like A LOT thank you and can u make a tutorial on how to make the game generate a random number and display it on the screen and the randomly generated number is the correct password?

[@UnrealART]

thanks glad you liked the video, you mean you want it to generate a new password for example in every 1 minute?

[@Frzbex]

kind of like that but a random password will be generated when the game begins and that will be displayed in a widgit@@UnrealART

[@UnrealART]

Yeah it's totally possible. you need to combine some variables together

[@Miaou_Bad]

ok :) @@UnrealART

[@julianking4793]

I am a bit late to this brilliant tutorial. Any idea how to reset the blueprint state? Say "On component end overlap" reset so when you go through te door and leave the hitbox the door closes and the blueprint is ready again to be triggered?

[@UnrealART]

Yeah it's possible. you may need to change the code a little to achieve that but it's totally possible

[@therealpfloder4730]

Hello Great Video, but do you know by chance (instead of doing the door opening with locationchange) how to do it with rotation(cause then the animation isnt smooth)?

[@UnrealART]

you can use the set relative rotation function. also keep the timeline but play with the values to get what you are looking for

[@LinlordLP]

10:30 I dont want to remove all Widgets, because I have a crosshair. What else can I do to remove the Keypad but not the crosshair?

[@UnrealART]

get a reference to the widget and then connect it to a remove from parent function

[@LinlordLP]

@@UnrealART I got it. Thank you. Very good tutorial

[@TheSilverFoxLP]

when i use the door with the keypad, all my other doors have keypads as well when i interact with them. even if the other door isnt suppose to have one. how do i fix this

[@UnrealART]

I think you can disable the colison box for your other instances in the level. you can use a boolean, make it instance editable and connect it to your flow

[@surya_616]

Hi bro I want to remove the specific num pad widget only from the viewport it's removing my all widgets from the viewport pls make a video of how to do that bro it will be helpful for me pls

[@UnrealART]

hi . use remove from parent widget node and then plug the panel to the target

[@DSX001USER]

@@UnrealART which panel?

[@levstepchenko5019]

Great tutorial, only one problem is that node "Remove all Widgets" kills other widgets on the level. Any idea what can be a substitution to that ? Thanks.

[@UnrealART]

Thanks. yeah you should use a remove from parent function and connect the return value from the create widget function to the target . let me know if there was any issues 🥂

[@levstepchenko5019]

@@UnrealART Already fixed that with the method you mentioned above, also it's better to change "remove all widgets" node in WB_numpad, becuase it will destroy all widget as well. I changed them to set visibility. Thanks for the reply anyway, it's always nice to see that author of the channel stays in touch with his viewers, not just drops tutors.

[@serizawareda7831]

thanks for the tutorial ! But isn't better to put the correct password as an Interger instead of a string ?

[@UnrealART]

have you tried it with an integer? I remember that using a string was better in this case but I don't remember the details. It was a long time ago. use whatever works! this is my philosophy in working with unreal ! 😉

[@ViNguyen-cr5gn]

Thanks for the video!

[@UnrealART]

You're welcome!

[@sinsamuhamad]

How can I make it so that the door only opens once when the correct password is entered? Currently, after the door is open and the correct password is entered, pressing 'E' shows the widget again.

[@UnrealART]

there is a flow control node called do once in blueprints. this makes the functions in front of it be called only once. you need to find the best place for the do once node in your blueprints and implement it, this should give you what you need.

[@tikal8746]

great video but it works better if you don't use remove all widgets nods and use remove from parents instead, my inventory was disapearing after crossing the door.

[@UnrealART]

Yes, you are right . Thanks for the tip . In my case I didn`t have any other widgets so I didn`t care about that .

hi, how did you replace the "remove all widget" in the door bp, I don't know how to do it.

[@tikal8746]

@@StellaKyriazi i'm no unreal expert, the teacher told me that the remove all widget from the door was removing my access to my invetory so he told me to replace the remove all widgets with remove from parents.

[@Arenac-d4o]

its good but there is one problem , when i pree E to remove my keypad my main hud also remove , ithing because u use remove all widget so how to correct it, as there is no option to add remove from parent node

[@UnrealART]

you need to call the remove from parent node and get a refrence to the widget you wanna remove and plug it into the function

[@Arenac-d4o]

It won't work if I do my widget stuck even press E, because of flipflop I guess

[@DatPhan-uo7ep]

is there a way so it only removes a specific widget rather than all of them? When I used it it removes some other widgets I need and doesn't allow them to re appear

[@DatPhan-uo7ep]

nvm found it "remove from parent"

[@UnrealART]

yes, you need to use the remove from parent function and for the target plug in the widget you wanna remove

[@willh546]

Hi, im currently following this tutorial and it was going great until i reached the section where you are creating the widget graph. I cant find a solution for this anywhere, but its not allowing me to use the "set text" node for the "input code" text block, even if the "text block has been ticked as "is variable", i was wonderinf if anyone would be able to aid in this anyway.

Maybe the collision box is parented to the door and moves up when it gets opened and you can't collide with it again. other than that, it should work if you do everything as explained in the tutorial .
