How To Open A Door With Mouse Drag | Amnesia or Phasmophobia Style - Unreal Engine 4 Tutorial

[@bill.i.am1_293]

for anyone watching this using unreal 5.1.1, in the BP_firstPersonCharacter blueprint, the "mouse input" is now "camera input". This had me confused for a second because it is laid out differently. All you have to do is: Under EnhancedInputAction IA_look, promote "action value x" to a variable, then name that variable turn rate. Then, connect the output from "Add controller input yaw" to the input white arrow of "turn rate". Then, connect the white output arrow of "turn rate" to the white arrow input of "add controller input pitch". This will make it work. Make sure all of the other original connections are still as they were and you will be set.

[@sayhelloethan]

should I connect anything to the target or val of "add controller pitch input"

[@Elitum]

For everyone having problems with the camera rotating left, but door moving right, change the variable "sensitivity" (which we made during this video) to a negative number (from 6,0 to -6,0). Worked for me!

[@MattAspland]

Thanks for pointing this out for others!

[@Zetrominator]

By default the SM_Door asset doesn't appear to have a simple collision box-- maybe just in newer versions. I think this is the main problem people have had in the comments if using that specific mesh, so either swap it out or keep reading below. To remedy this, find your asset (not the blueprint) or click the magnifying glass at 1:09 to jump to it. Open it up and at the top (File, Edit, eg.) select Collision, and add [Box simplified collision]. You can go to (Show)->SimpleCollision in your viewport to verify the green box around your door now. Save and close. At 5:36 change Draw Debug type from None, to Duration. This will enable the line trace shown in the overview and let you troubleshoot if your trace triggered by LMB is hitting the door or just passing through it. If you were missing a collision box, after completing the tutorial you were likely either unable to interact with the door or just seeing a red line shoot through it.

[@TuberStevo]

you saved my day :) TY!

[@Euenise]

Thank you so much, I have spent a whole hour trying to figure out what the problem was and even uninstalled and installed Unreal

[@Zetrominator]

@@Euenise Woo! Glad I could help

[@stevenwynn819]

Another great video. One suggestion for modifying the blueprint would be to use the nodes "Set Timer by Event" or Set Timer by Function Name" in place of using Event Tick. The timer would only run when the player character is looking at the door (or you could add a trigger volume). That way you could have many doors in a level without worrying about them all executing the branch check with every tick. Just a little more efficient.

[@MattAspland]

Thank you! And yeah you are absolutely correct, that would be more efficient than the event tick. The tick shouldn't be too bad, but yeah if you have a lot of these doors in your level than it might be quite bad on the system. Thanks for letting others know too!

[@TiNNx]

@@MattAspland Hi, could you make a tutorial on opening these doors without the locked camera movement when interacting? Opening doors using this method can cause inversed ways of opening doors,with no camera lock if you moved your mouse to one side fast, the door would slam. I know in Unity there are quite a bit of tutorials on this, but although this method is a great way of opening doors, locking camera movement feels clunky.

[@deadsamurai2011]

same with a collision box/capsule or circle to enable and disable the input

[@EspacX]

Awesome, exactly what I needed. I also used this basis to make a manual sliding door by inputting the player velocity.

[@nextanvil3346]

Aw man that is so cool I really like that you can open a door manually instead looking at the animation that is so cool thanks for the video keep it going

[@MattAspland]

Thank you, yeah it's a great mechanic! Thank you :)

[@funagengames1177]

Thanks Matt! Your Unreal tutorials are the best on youtube and you always seem to have just the right tutorial for whatever I need. I adapted what you taught in this one to using a crank to reset the arm on a trebuchet in my game and it works perfectly!

[@The_Fennix]

I am using UE5, but the issue I am having is, the door is turning opposite what I am doing, so if i move my camera LEFT, door goes right, I turn Right Door goes left. Also noticed is their a way to do it When Moving Up Move the door away Like Up = Left, Down = Right? So it would look like you bringing the Door Closer to you and away?

[@epetubaa4773]

Great tutorial. Worked right away. Thumbs up!

[@zebra486]

idk if this could be answered, but how would this be implemented with the new input mappings system? i have been tinkering with the bp based on this video with the new input mapping and i can't seem to get the yaw working right

[@xgamerunknown6414]

I was totally wanting this. I'm so glad I subscribed to your channel

[@petervandersteen1418]

When I've dragged two of the drag door BP into the map, only the most recently will open even when looking and attempting to open other doors. Do I need to create new BP's with different variables for each door?

[@pedrorosa5782]

I would like to know about this too

[@focalaxisssx5490]

The video is very educational, and I've got it working client side, though I was wondering if there was any way to make this run in multiplayer?

[@ThatsTheMidnightGamer]

Me too. Whenever these things need network replication it seems like the entire code changes. So when I try and quickly edit the code to be network replicated, its always more complicated than I imagined.

[@VictorBiryukov]

Awesome video. Thanks. But does anyone know how to make same thing in UE5? I got stuck in a moment when you have to "get turn rate". There is no "get turn rate" in UE5.

[@InquisitiveTurtleStudios]

Make sure you're grabbing "Get turn rate" from the blue node in the "Cast to (...)" component rather than the white arrow! I also made that mistake at first.

[@pwnonator]

I would Love an UE5 version of this. Somethings are different and im stuck at "get turn rate" and some things seem to be different

[@victorblanchard7774]

The answer is in the video at 7min17

[@potaterjim]

I'm having a problem, using the standard first person package, it isn't recognizing the hit to the door. When I get to the branch just before the CasttoDoor, it always returns a false. Even when I turn on the linetrace visibility, I can clearly see that the linetrace is penetrating the door

[@lpking2005]

I had this issue also and found that i had to add a box collision to the door and set the collision preset to 'BlockAllDynamic'.

[@krzysztofbogdanowicz4543]

Fantastic tutorial ! One question - how to make classic door which are opened only to one side (can not be rotated around frame) ?

[@TAMEJoKeR]

I have just done the same thing. It would be the same concept except adding in the minAngle. So having a max open angle and min close angle. I also added a forward vector check so that you can open and close the door with the correct rotation depending on the side you are standing by getting the sign vector of the forward vector of the camera (+1 or -1) to determine which way i was facing and then multiplying that to the output of the make rotator which gave me the desired effect.

[@theofficialamt6626]

Can you make a series on a Phasphobia style game. Can't find anything similar.

[@YuBGamerzBen]

This is cool, but the door doesn't really react like you'd expect when opening from one side (moving camera to the right when trying to swing door to the left). Also if you have more than one instance of the door in your world. The first door opened is the only one that opens. The rest just open and close the first door clicked on.

[@Perkins.Garage]

Have you managed to figure out a workaround? I’m currently struggling with the same issue

[@Perkins.Garage]

Sorry, to be more specific the the issue where you can’t open any door but the first door in the world

[@rifat.ahammed]

Thanks again, Matt, but I've got an issue. If I rotate the door with a big max open angle , the door mesh enters into the wall , making it feel like there is no collision. And if the main character stands in front of the door and tries to open it , it won't stop. But I want it to collide with colliders and seems natural. How can I do it?

[@wookiebush7449]

This doesnt work, maybe because of a 5.1.1 update. My setup is identical but when I click on the door it immediately jumps to the 100 angle and I can continue to swing it open through the wall until it reaches the -100 angle, then it immediately jumps to the 100 angle again.

How do you add sound to it?

[@Jimmybear06]

Is there a way I can add a door sound effect as I gradually open it?

[@MattAspland]

I assume you could maybe get a very short clip of a sound effect and play that every time you update or move the door? I haven't looked into that one too much, but I assume that would work, you've just get to get a sound effect which would sound good with that. Or have a longer one, but only play it when the door (or your mouse) is moving.

[@stuffedturtle1426]

On the true and false (within the Branch just after the Gate). Add 1 more then node. Then 0 will continue like normal (Into the timeline), the false sequence will have the same set up (false Then 0 will go into the timeline). Then within the True sequence, out of Then 1, put a Play Sound at Location. choose the sound, then grab a reference of the door static mesh (Or the handle etc. Whatever you want it to be). Out of the Door reference get a "Get World Location" and plug that vector into the Location of the Play Sound At Location. Copy those 3 nodes (Play Sound- Get World and the Door reference), Then paste it and connect it to the Then 1 in the false section of the Branch node. For me I put a delay between the Then 1 and the Play Sound at Location so that after 1 second the sound will play (Simulating the door hitting the door frame). Hope I made sense- feel free to comment if you are confused or need any more help :D

[@Salaudo]

My only issue with this (and I've been struggling for days to figure this out) I just really wish the door would follow the cursor if that makes sense? Rather than it turning dependent on the way you turn the camera. And I would like for it to be more clear on how to limit the door to only opening one direction

for some reason it only works on 1 door if u try placing more all doors will affect the last added door do you know of a fix for this

Hi, if you select the action mapping for our interact, or drag mouse, you can un-tick "consume input" in the top right. This should allow you to place multiple doors down and use all of them :)

Make a second sensitivity variable that's negative from the original. Set up a trigger on the side that doesn't work. Make another AddLocalRotation that uses the new sensitivity variable. Example... Sensitivity Side A = 6 ... Sensitivity Side B = -6

I think you can do that by getting the "Get player controller" node then connect it to the "Cast to" Object input, then in "Get player controller" you can specify which controller you want to cast to (ex 0 is player 1, 1 is player 2, etc).
