Unreal Engine 5 Tutorial - Quest System Part 3: Quest Givers

[@shifugurugaming]

Another method for Third Person: - (Remove GetCameraManager Node) - Change to LineTrace node to SphereTraceByChannel - GetActorLocation = Start - (GetActorForwardVector * 100) + GetActorLocation = End - Radius = 20 - GetOwner -> Make Array = Actors to Ignore

[@pottz91]

does not work.. halp me

[@blacksage81]

Thank you! I had a gut feeling that was the move to make, I had to swap out the line trace for sphere.

[@mrh8984]

@@blacksage81 @sonny5974 whats the meaning of a Sphere line trace vs Line?

[@mrh8984]

Awesome this worked!

[@motazturk]

For Those Following the Tutorial with a ThirdPerson Blueprint, Just change the Line trace to a Sphere trace, the start and end should be as Follows: Get Actor Location + (Get Actor Forward Vector X 150) Radius about 120 Trace Channel Camera That way you will interact with the Actor/NPC in a 120 Units Radius that is 150 Units in front of you

[@uchihakidd9026]

Thanks a bunch! I finally got it to work!

[@itzyaboytunez4182]

This didn't work for me because the radius was too large, but I implemented an alternative solution using box colliders for the interface after playing around abit with it.

[@rasbe7210]

oh my god thank yo

[@KenLinx]

If this still doesn't work, also replace 'Get Player Camera Manager' with 'Get Player Character' and set the multiply value to 0 instead of 150.

[@charles8059]

Thank you!!!!

[@seeRK108]

1 if u cant see the Print string quest in thirdperson so just increase(GetActorForwardVector * 5000) it will work but it is not the best way 2 just change the Linetrace to SphereTrace It will work

[@voryszlo]

the easiest. add 2 scene component to the character's BP. first to the center character's BP. the second at a distance with which we want to interact. 1 get world location to the beginning. 2 get world location to the end and that's it.

[@nathanmiller8818]

Anyone that has used is prior interact system: Simply add a new function to your interface (I called mine quest interact) make sure it has the Quest ID output and input! then under the npc or other item you want to have the quest give them the quest giver component (and of course your character still needs the quest log component. After that double click interact with (on the npc etc..) to create the event, call in the quest interact, for the quest ID you will grab the quest giver component, grab the quest row name then have it as the quest ID, and the quest giver component as the target. Now click the quest interact and attach the ID quest to the quest ID and boom! Everything else is the same except under the quest giver component, under interact with you want to call in the quest interact (leave everything blankc and fill it out under it like he does above. This should all work as it does and not break your previous interact with function.

[@arthurmarquis764]

@Ryan Laley how about using the new input action system instead of the depreciated? How can I do that?

[@MaksymilianWawrzyniak]

Just add new Input Action eg. "IA_Interact" set as a bool with only one state "Triggered" - then add this action to your Input Mapping Context and set up the key you like eg. "E" - then in Player Blueprint add event "EnhancedInputAction IA_Interact" instead of "InputAction Interact"

[@rasbe7210]

Thank you for your video! I learned a lot. :]

[@dawidpiejko9917]

Hi, one important question, what should I do if I have one Interaction Interface from your equipment and pick up series? Just add input ObjectiveID to it?

[@imwheeliebad]

UPDATE ON THE THIRDPERSON ISSIE: after redoing the line trace blueprint it seems to work fine :)

[@ergingoksu9567]

do you know a solution on 2d topdown

[@imwheeliebad]

@@ergingoksu9567 Sorry, been doing 3rd person so haven't dug into top down mechanics.

[@epeli9915]

and how you did it?

[@imwheeliebad]

@@epeli9915 Just like in the video...Deleted the Line Trace node and redid it the exact same way, now it works ;)

[@agst7095]

@@epeli9915 I fixed this issue by increasing the multiply number in the InteractTrace function to something higher than 200.

[@danzalotX]

he said that the quest giver component can be used differently than having an NPC. Such as a timer based thing or event based thing... I'm trying to make a tutorial in the beginning of the level. does anyone know how it can be implemented that way? i was thinking perhaps trigger boxes when entering a room, and give the box the quest giver component? or is there other ways of doing this? i'd appreciate some ideas. thanks :)

[@jakespencer917]

Really thinking there should have been an interactable main BP for your different series that you branched out of for this, items and equipment.

[@TheOfficialAgNO3]

Hmm.. Sadly this isn't working for third person at the moment. Is it the line trace by channel set to camera? Visibility doesn't work for me either. Any suggestions Ryan? Would really love to continue this tutorial, it's great.

[@imwheeliebad]

Did you find a solution?

[@dergamegamer8176]

I have now the same problem. When someone find a solution. Feel free to share :)

[@jesperrasmussen2058]

@@dergamegamer8176 Did you solve it?

[@jesperrasmussen2058]

Did you solve it? im stuck :( sadly no help here in the comments

[@motazturk]

so i just did a normal line trace but instead of camera i did from player mesh with 200 multiplier! not as pretty but works

[@TrocarQueen105]

I'm using a VR template, and wondering if this tutorial still applies? I'm at a similar block as found in the comments, but all seem to say they're working in third person vs the first person in the video. Will update if I find my answer in my research. This video series has been fantastic.

[@matthewcheung4296]

Even in first person gamemode it's not really working for me. Followed every step and also followed someones instruction with the new input mapping

[@Ehlemdej]

Could you please update or explain how to do the interact input in UE 5.1? I tried to do it while following your other video about this change, but since it's not made for this quest series, I can't seem to make it work now and I'm stuck 🤷🏻‍♂

[@Ehlemdej]

Update: I guess I did make it work. Somehow I have to look a bit up, so that my camera gets very close (zoomed in on questgiver). Only then it will interact with the questgiver. I guess it has something to do with third person mode. Since this tutorial is first person and doesn't have this issue

[@TheShadowCamel]

@@Ehlemdej Did you find a way to make it work better? I know there is a different way to do it with Collision capsules as seen in his previous videos. They were about UE4 quest systems that he made 4 years ago.

[@TheShadowCamel]

@First Last You get videos earlier if you are a supporter on patreon. 😎

[@imwheeliebad]

Not sure it is related to the input changes, something to do with ThirdPerrson vs. First i think

[@HadesRage93]

To fix this Get the Camera Boom Get its world location plug it into start then plug it into the top Add input node and plug into the End for 3rd Person Tracing. The reason being the Camera Boom is at the center of the Default third person Character.

[@theshtshowlive]

My question here is: Since I already have an interaction system in my project, can I just create a new Function in that interface or would it be better to create a new interface to receive quests when interacting?

[@deliciousagony]

Yes that is what I did. Just added it to my existing function

[@lylejoslyn2638]

@@deliciousagony So when I added it to my existing interface it turned my interact with into a function compared to an event, how did you fix this?

[@deliciousagony]

@@lylejoslyn2638 for me it just works. I have combined this quest system with the interaction system from Michael Pattinson. I am thinking to make a video about it on my channel later on

[@pterafier]

@@lylejoslyn2638 just copy paste your event code into the function

[@StopItRyan]

Method for line trace for third person character I used: Get Player Character Get Forward Vector (Root Component) [rest as normal in tutorial]

[@grimmthemisfit9168]

hey I was trying your method when I realized that I can't connect Get Player Character into the line trace, nor the forward vector, maybe I picked the wrong thing but I'm not sure :,)

[@rarisninja461]

does implement interface dosent show up for me

[@descendantsonline221]

I came to the same conclusion , it simply wasnt working. after running in circles for a bit the 200 distance needed to be doubled and it works now.

[@teodorfredriksson]

Ok so i've rewatched the videos 1-3, and i've tried all the examples below. Is anyone else still experiencing trouble with interacting? More specifically, that no message is being shown when trying to interact with the NPC. I have tried: -switching to sphere trace -changing from player camera manager to get player character (not the pure function, but the game function) -changed the radius to a variety of values -changed the multiply/add value to a variety of values -changed trace channel to camera -actors to ignore -->make array Any tips?

[@ilithyia7445]

same here :(

[@matthewcheung4296]

Havent got a clue on how to fix this either :-

how do i get break fquestdetails in third person

[@giacomofumagalli8532]

Hi everyone, I dont get why it doesnt work on third person, anyone tried to make it work on third? Thank you

[@WaHBz86]

Does anyone know how to get this working with ThirdPerson? I've tried a bunch of things, including some of the suggestions in the comments, but no luck on my part.

[@KenLinx]

Here's what I did: Replace 'Get Player Camera Manager' with 'Get Player Character', then replace 'Line Trace By Channel' with 'Sphere Trace By Channel', set the radius to 90, set trace channel to camera, and set the inputs and outputs to the same as what was shown in the video. Then, finally, set the multiply value with 'Get Actor Forward Vector' to '0'.

[@puffpuppy420]

@@KenLinx first of all THANK YOU! This worked for me, however now its pulling three quests instead of just one. Any idea why?

[@KenLinx]

@@puffpuppy420 I didn't have that problem so I don't know how to fix it. Maybe double check that you've followed all the instructions correctly? Sorry I can't be of much help; I haven't touched this system in months.

@@puffpuppy420 I'm glad you were able to resolve your issue, but what's enhanced system? Did an Unreal Engine update change something?

[@BlazeGamesUK]

For anyone doing 2d, I did a sphere trace but this wouldn't work for some reason, so I did line trace and it worked. Just in case it helps anyone!

[@RagbroGaming]

I dont know what im doing wrong but i dont get it to work :(

[@robvan6274]

Yeah ive hit a roadblock. Ive attempted every single fix within the comments and none worked. I tried using the actor location, ive tried using the spring arm.

[@pottz91]

same

[@jakespencer917]

with what? Confused what you are attempting to do here. Using 3rd person or 1st person? Assuming it is the trace.

[@anthonytaylor7362]

This playlist order is out of it.

[@katiekaliber]

Somehow it prints the quest 5 times for me every time i interact. Anyone got an idea of what is happening?

[@Ekelmonsterchasti]

I have the same problem today, but I found a solution: I'm working with "EnhancedInputAction" and used "Triggered" first. Changed it to “Started” and now it works. So its maybe just your input action from your player character :)

[@arthurmarquis764]

This is old so may not help you but the next guy maybe. Check that you are coming off the right pin when pressing the key. Try triggered instead of pressed or whatever else you might be using.

[@jakespencer917]

mine is doing the same, and I am not 100% sure why. going to continue tutorial and see if fixed but that is an odd bug.

[@zjaranyjoe7456]

What if I dont need those trace cuz I have dialog with npc and want give quest just at the end of that?
