how do i get an actor id?
#blueprint
wise jewel
devout condor
@frozen spear thanks, I didn't realise I can add other actors, I thought chiald actor, mean that it had to be a child of that actor as if it was a base class
frozen spear
you can...but...it will cause you headaches unless the other actors defaults are exactly as you want them and they dont change much...my atempts to use it in pure bp projects always leads to cases where i was not able to access or change a given variable on the child
wise jewel
how do i convert it to int? for example? @undone imp
frozen spear
it ends up more frustrating then helpful unless youre doing this in C++ where you can correct the issues with custom getters and setters for the child
undone imp
display name for actors spawned on runtime will have a class name and a number. So you can get last few characters, and that will be an int, and you can use it as random seed or just add to a random function
you can probably also convert string to a number
straight up, somehow
but I can't tell from memory
if there is a node for that
frozen spear
you can, just drag the string into an int setter and it will create the macro
actually i might be remember it wrong hold on
just to be sure
wise jewel
it's kinda mmm weird to get the label to get a seed
isn't there something more... clean so to speak?
undone imp
@wise jewel you can just get a ranodm seed for each actor when they sapwn
simply begin play -> Get random number -> store it
undone imp
you can do it in a construction script then
frozen spear
undone imp
same thing.
it will be updated each time you rerun the script (move / update the actor),
but if you want random nosie, that will beit
hmm
also.. what is the problem actually
each time you use a "random" node the output will be different
so you dont actually need to do anything
frozen spear
you could just convert the whole name to string then set to int...it would create a unique identifier for your actor
if thats what youre looking to do
undone imp
@frozen spear what does it actually do? is it length? or what?
whats the int value of "a" or of "hello world"?
frozen spear
it convert the char into thier int value i can actually print it out for you hold on
wise jewel
ill try the label thing later
for each instance of the actor the random will be different?
wise jewel
it's non deterministic?
wise jewel
it's great
thansk it does work with setting randomin a variable
cool
so i'm trying to do this:
when i enter in a the radius of these flickering lights, i want to change color or some other values.
now i'm setting these things INSIDE the character.
a better way would be to use an interface
am i right?
i just call some "use" function
and the lights are responsible of their internal logic
am i right?
frozen spear
it only stores any number strings only
undone imp
heh
@wise jewel depends. You can have lights with a collision sphere that triggers when player overplaps it
or player can have a collision sphere.
wise jewel
i'm pressing a button now
undone imp
then interface would be good
wise jewel
when im overlapping
undone imp
if you plan on having other things react to player
wise jewel
so they change only if im in the radius
this is what im doing inside the char
but say the light is also controlling the color with some internal logic
undone imp
yeah, that works. just make the color from RGB and randomize components or something
wise jewel
on the next tick it gets it will override whataver get set from the character
am i right?
undone imp
no. it will change each time player presses a button
INPUTS trigger once when pressed
AXIS trigger every frame
wise jewel
it works like i said
undone imp
if we are talking about inputs defined in project settings
wise jewel
maybe i didnt express myself well
my light is setting color every tick, with some logic.
if i press a butto and tell "change the color"
it will maybe change it, but on the next tick the light gets, it will go back to what it was doing
i have 2 things that "compete" , that wants to set the same color
i've tried, and it works like i said. i tought it was quicke to ask then to try it
😛
undone imp
so what are you trying to achieve? that button will stop the flicker? or start it? or set it to a specific color?
undone imp
maybe I missed something
devout condor
any idea what is happening here?
undone imp
yes
Turret here is not a turret class
is a child actor component
you need to get actor instance (or something like that) from the turret
and cast that
wise jewel
i want to display a in interface in viewport, can i use gamemode blueprint to display it for example? i would put it in level blueprint since it would be a "global" menu
can i use any blueprint to display it?
undone imp
player controller would be a good place for any HUD
or actual HUD class
but game mode will work
wise jewel
ok
mortal heron
Hi, I am currently using the 3rd person template blueprint, and I'm using another map, when I click play, I'm not controlling the player and the camera is stuck in the ground, any help?
undone imp
@mortal heron you have a player start on the map? or your charcter?
undone imp
player start doesnt have to be possessed.
Make sure its placed in a valid location.
For example if it clips the ground it will show "bad size" msg
instead of a normal icon
mortal heron
i've put the player start away from the ground for a second, away from the map and it says bad size
undone imp
maybe there is something blocking it? invisible mesh? large collision volume?
frozen spear
@devout condor you get the children components and cast the item in the array to the class
mortal heron
i imported the map via .fbx
undone imp
@mortal heron then it probably doesnt have proper collision, and the whole map is a solid block
move the spawn above the map, or disable collision
to see
devout condor
@frozen spear this that necessary?
undone imp
@devout condor "Turret here is not a turret class
is a child actor component
you need to get actor instance (or something like that) from the turret
and cast that"
frozen spear
you didnt read when i said..."unless your in a c++ project where you have better control of the child variables"
or the part where i said "why you would even want to add it as a child instead of finding a better solution thats more flexible?
undone imp

Howdy doody guys and gals! I am on a quest for someone elses experience! I wish to add downforce to an F1 car i threw together... no coding experience... I don't need a full on tutorial... just have this question... Is this something i will manage? Or is downforce via blueprints tricky.. i struggled to find any info on the matter >_<
frozen spear
zethfoxToday at 11:04 AM
it ends up more frustrating then helpful unless youre doing this in C++ where you can correct the issues with custom getters and setters for the child
devout condor
ok, I think I understand, it just looked unnecessary sorry
undone imp
@mortal heron in the top left click show > collision, see if it is inside any volume
frozen spear
in c++ you would code a custom function in the parent that rotates the turrent and call that function as blueprint callable
undone imp
or click on the map, if its a single mesh and disable collision
frozen spear
with a float or vector passed to it
then it have it rotate the child in C++ instead
undone imp
@unique holly simple force in one direction or a full simulation of aerodynamics?
unique holly
simple force, i just need it to handle humps a bit better at speed >_<
undone imp
You can "Add Force" every tick, using actor "up vector" and multiplying it by -1 and by some fraction of the speed.
not sure how it will interact with vehicle simulation
mortal heron
should i choose complex or simple collision for all meshes?
unique holly
i think thats what i'm looking for, ty @undone imp. i'll mess round with it and see what i get >_<
undone imp
simple is faster, complex is more precise 🙂
@mortal heron you can use an option 'use complex as simple" in mesh properties
mortal heron
kk ty
undone imp
to have collision that matches the goemetry
unique holly
Yeah, im on about 4 -5 months of learning and only one of those is unreal... so urmmm.... screw precise for now >_< the double wishbone stuff was 'fun' enough...
lol.. cross wires, ty peeps!
imma go try again..

ughh my idea of procrastinating on my game project is come on here and help other people solve thier problems clearly im messed up in the head

someone posted a how-to on Twitter on detail panel customization using blueprints a few days ago, but I can't find it now... anyone know what I'm talking about and have the link?
unique holly
@undone imp How does my first non-tutorial blueprint look? It seems to work, the help is very much appreciated!! http://prntscr.com/sdragw
thin rapids
@unique holly why did you truncate that float twice? you could've just multiplied that int to another int
undone imp
@late cave you are probably talking about editor scripting tools by Elhoussine Mehnik.
Some of it can be enabled in plugins, some is still WIP
unique holly
ty! Danielll... i am that noob >_<
undone imp
@unique holly you are using X from the velocity
which means it will only work if you are going "world forward"
unique holly
ahh. thats not local >_<
undone imp
you need to normalize the whole vector and get the length
late cave
@undone imp YES! that's what it was... thank you 🙂 https://twitter.com/HoussineMehnik/status/1257762472196476929?s=20
so that's not out yet?
undone imp
I know that you can make custom editor windows with widgets. I did that. You can use them to customize details of an actor.
However, AFAIK you can't yet edit the details panel itself using bp / widgets
but you can make your own windows / tools.
@unique holly use the whole vector, not just X/Y, since otherwise the effect will be weaker if you go up/down hill for example
late cave
right... the documentation only mentioned Slate so that answers why I wasn't able to find anything official
vivid plinth
Okay fellas. I found something odd. I have a character that shoots a projectile blueprint. This projectile has a sphere collision that triggers an explosion effect when it overlaps a static mesh. This projectile fires 4x per second. Upon a LOT of testing it appears that no matter what this thing hits/overlaps, the event is only called sometimes. Like 3 out of 4. Timing doesn't matter too much, I spaced out my shots and still, like 1 or 2 out of 4 don't fire. It's very random. I'm not sure what's causing this?
Here's a quick display of several projectiles. Some of them trigger the effect, some of them don't. In the same spot.
Does Unreal have some kind of limit on emitter spawns per time? or something?
undone imp
maybe when you rapid fire one projectile hits another or something?
unique holly
@undone imp Fingers crossed this is my last pester >_< http://prntscr.com/sdribe Am i close?
undone imp
and its not coded to explode then?
@unique holly closer...
normlize returns the vector with a length of 1
so you need to get a lenth of the normal velocity
up vector * -1 * velocity length * some constant
smoother solution would be to make a curve that maps velocity length to downforce multiplayer
unique holly
@undone imp for now, i'll stick with this, tyvm! I have loads to learn, lots of other things to do, just felt a shame to leave this car without at least some semblance of realism, It now does not fly at all humps... hopefully not locked to world x >_< http://prntscr.com/sdrlxa
undone imp
yeah, this will work
vivid plinth
Generate overlap isn't the problem since the effect DOES work, just for some reason not 100% of the time. Ignore the replication, I'm testing locally. The problem AFAIK is the engine doesn't seem to want to do more than 1 collision at a time.
undone imp
@vivid plinth but if you hit something that is not a static mesh actor it will not trigger
vivid plinth
Like if I launch a single projectile, it works, but then sometimes, it just doesn't
undone imp
like other bullet
vivid plinth
The problem is not that it doesn't work, it just for some reason falls short at random times. Casting because I don't want to trigger on every overlap (like the player who spawned it)
undone imp
again, it might fail cause you hit something else
vivid plinth
wouldnt an ignore self work better
@unique flicker Player is not self
let me try, i did this before
unique holly
https://i.gyazo.com/3c58b111463cc10010da3bc054e4240c.mp4 @undone imp The car you saved from obscurity! now to learn how to strap guns to cars >_<
vivid plinth
anyway on event overlap doesn't trigger sometimes. it's part of the engine....
@unique flicker but why? then why would anyone use it
short coral
Hello, can someone help me figure out if i understand this correctly? I'm profiling and i'm trying to figure out some slow downs , one of the most reoccurring things are cpu stalls - wait for event , can these also come about from delay nodes as well? Or what kind of nodes should i be looking at exactly , i'm kinda stumped
undone imp
for fast moving projectiles, line traces are probably good enough
cedar sleet
@mint bane do you know how to create a blueprint class
cedar sleet
create a new class of the type Actor
actually create a class thats called TriggerBox sorry
mint bane
yup
cedar sleet
inside of the class click the + sign to create an On Component Begin Overlap event
vivid plinth
but once u hit things really fast, it becomes unrealiable
@unique flicker its just so disheartening to see two fireballs explode and then a third one just delete :(
will try alternatives to overlap I guess
cedar sleet
inside that event, drag the CollisionComponent out onto the grid and call Unbind all Events from On Component Begin Overlap
this is the function that will disable the overlap event we just created
mint bane
alrighty noted
cedar sleet
the problem we have currently is any actor can set this overlap event off, you want it to just be your player that can set it off right?
mint bane
yup, and play it once
cedar sleet
so we drag off Other Actor and cast it to your players character class
trim matrix
what exactly is construction script for and how is it different from my normal blueprinting?
cedar sleet
correct
mint bane
okay ty
cedar sleet
@trim matrix when the class gets created the constructor runs. this is generally used for setting variables default values and such
trim matrix
ah ty
cedar sleet
so for example i have a class called BP_CharacterBase. what i do is i take Other Actor, cast it to BP_CharacterBase, if its successful then i unbind the overlap event just like this
cedar sleet
correct, so only your players character can activate it
mint bane
okay neat ty
cedar sleet
then after you unbind the events for the overlap event, simply play your dialog
you can even go a step further and delete the trigger box after the dialog runs if you want unless you will need it again
mint bane
urm, idk because, in a thing i did before whenever id walk back it it would play over the already playing audio
is there a way for it to wait for the current one to finish
then play if you go back in,
also, would this then play around the character or in the place the sound is coming from, lets say its a thought dialog it would have to be playing around the characters head?
sorry if im asking too many questions
cedar sleet
if you know how long the audio is you could create a timer with a delay thats the length of your audio (such as if your audio is 60 seconds you would add a 60 second delay). so you disable the overlap event, play the audio, start the timer, once the timer runs it re enables the overlap event
play it from the source of your character, im not sure if it will follow it around or not though
so create a function, lets call it ReEnableOverlapEvent
mint bane
yup 
cedar sleet
nevermind delete that function
vivid plinth
@vivid plinth you can try using a collision sphere/ capsule
@unique flicker I am using a collision sphere, I have tried printing every overlap and it seems the engine just doesn't want to give it 100%
like I fire 8 or 9 shots now, it works fine, then #10 just DOESNT lol
mint bane
okay !
nevermind delete that function
@cedar sleet
cedar sleet
do SetTimerbyEvent, set the initial delay to whatever length your audio is. then in the little event (the red/orange box) drag off of it and type custom event to add a custom event
trim matrix
difference between functions,macros and events?
cedar sleet
then drag the Collision Component back off and bind the OnComponentBeginOverlap event again like this
then link the event to the OnBeginComponentOverlap event shown here like this
vivid plinth
I might be okay with 10% of shots not exploding but it's just extremely annoying
mint bane
alrighty!
vivid plinth
just curious how fast is your missle flying
@unique flicker 15000
let me try dramatically slowing it down and see if there's a difference
cedar sleet
@trim matrix functions and events are a little weird in blueprint, but functions are usually used to shorten your nodes so to speak. so for example instead of having a ton of nodes running taking up alot of space, you can put them into a function and just call the function. events are usually bound events like the OnComponentBeginOverlap event i was discussing above, events can be used as RPC's so you can call functions to run on the server, client, multicast and so on. macros i cant really explain as im not sure if their the same in bp as in c++
trim matrix
ok ty @cedar sleet
vivid plinth
Okay slower projectiles don't appear to miss any overlaps.
cedar sleet
@mint bane im heading out so feel free to ask here or tag me if its related and ill answer when i can or unless someone else can
vivid plinth
This is a bummer because 15000 was very fine tuned and felt good. Idk how far I can change it.
vivid plinth
I changed it to 2000 just for testing
Let me see how far I can push it before it starts clipping those overlaps off
little spade
Can someone explain to me what "sweep" and "teleport" do when enabled?
vivid plinth
Okay at 10,000 every single shot exploded. At 12,000 it started to miss a few
little spade
I'm trying to follow this tutorial
vivid plinth
at 11k it misses too. I think 10k is the cutoff for 100% trigger
I can probably make this work but it will mean adjusting some stats in my game. Thank you for the support @unique flicker
tight schooner
@little spade I think they have some mouseover descriptions. Sweep checks for collisions along the path of movement. Teleport skips physics update or something.

We have a very strange problem and it would be great if anyone could help us. We added a loop that continuously kept updating the server to see if it would fix a problem we previously had. However after deleting the code for the loop it seems to still be running in some way. We even reseted back to an old version and the code appears to still be running, like some sort of ghost code. Is this even possible?
We are new to UE4 and Blueprints

i've seen a tutorial where they use remove from parent to hide a widget. i've also seen another tuto that i'm not able to find again, where it shows a better way, so that the widget is only hidden and i don't have to create a new one each time.

How do i set the Widget class if i do it manually?
@trim matrix with 'do it manually' do you mean doing it in blueprints instead of setting it in the component?
trim matrix
Yes
hollow flame
@unique flicker please explain more
thin rapids
Yes
@trim matrix i'm gonna take a screenshot to send you how
trim matrix
i clicked on the blueprint and got the details right, probably i can set everything there?
thin rapids
i couldn't take the screenshot but i'll tell you how
@trim matrix first you create that widget component
after that you'll want to use the 'create widget' node and set the widget you want there
after that you'll want to get a reference of your widget component and connect it to the target node in 'set widget'
and in the 'widget' connector in the 'set widget' node you will put the return value of your 'create widget'
trim matrix
like so?
thin rapids
yes
trim matrix
That unfortunatelly doesnt work
thin rapids
but instead of the 'add widget component' put the widget component reference from your character in the set widget
stoic mesa
quick question, what would be the best way to get a reference to a specific object out of a group based on if it is the closest to the player character

thin rapids
what do i need to do with the above blueprints?
@trim matrix remove the 'add widget component'
and in the 'target' of 'set widget' put the widget component you made in the character
trim matrix
Ah
Okay but i need the add widget component
because i only want to add that component by the server and set it replicated
because i only want to change the name by the server
to be synced for every player
nvm, i am just using it by adding it i the components tab 😄
hollow flame
@stoic mesa
thin rapids
nvm, i am just using it by adding it i the components tab 😄
@trim matrix yeah, it's easier like that, if you want the name of each individual player get the player name from the player state if i'm not mistaken
trim matrix
Yep
Do you know where i can get the player state? 😄
Ah it is directly saved in the pawn
hollow flame
@unique flicker do not use overlap for spawning blood at location, use event hit or line trace
thin rapids
Ah it is directly saved in the pawn
@trim matrix yep
or you can also type 'get player state' in the blueprint editor to add that
trim matrix
kinda equals to get player controller i guess?
stoic mesa
this is what I have so far slack im just struggling on how I get all the distance variables from the actors and compare them all

Hey guys, I made a radial menu as you can see in the picture. The outer widget_icons are created by code and added to the menu widget. While creating those widget_icons, I saved them in an array. Now the problem: When I try to change the appearance (As Example the size or visibilty or texture) of the widget_icons, it doesnt show the changes on screen. By debugging I found, that the values indeed changed, but werent shown on screen. Any ideas? Do I have to update the widgets manually somehow? Thx 🙂
Im using bps btw
hollow flame
@unique flicker you can try as you want, but you can run this line trace on tick like this
use this separate from overlap function, use overlap for other purpose
ok so you can run timer event after every x seconds when overlap, and after delay you can clear timer
trim matrix
@thin rapids
This wont work (btw i needed it because i need to store the instance 😄 )
thin rapids
did you try using the return value in the 'widget' connector? (you can still leave the SET in there though)
hollow flame
@unique flicker if you don't want tick, try this, please remember, it only return location if line trace is running and hit the location, you can also create two scene component and make it child of sword, and then you can get first scene and plug into start location and second scene component to end location, use doN instead of do-once
thin rapids
but the widget is not visible
@trim matrix is the name of the character filled?

Just getting involved with editor widgets, so maybe I'm missing it but I couldn't figure out a way to do this yet: randomizing cell data in a data table via button (i.e. think of randomizing first name/last name). There are other ways to achieve this of course (much easier ways without editor widgets), but wanted to know the limits of editor widgets and if this type of thing is possible with them.
frozen spear
using just widgets graph you mean @daring summit
?
you should be able to, tho whatever you run into problems with you could easly code the logic into gameinstance bp and have the widgets communicate with it through blueprint interfaces...

Really getting bummed out with physics toggling in UE
I created child actors which are basically identical to their parents - I want the staticmeshcomponent in the child to turn off physics simulation while it simulates in the parent
The tickbox is greyed out in the child, and trying to override it on beginplay confirms my suspicions - it does nothing
I created the child in the first place because I couldn't seemingly reliably turn physics off when spawning an object

hey guys... so I'm trying to make a trigger box inside of a trigger box that is a specific size smaller than its parent - this outer trigger box is scaled to whatever size to fit an area - I know I can set the scale on the child trigger box to .8 for example but the larger the entire blueprint (outer box) is scaled - the more of a difference there is between the out and inside box
I'd like to specify X number of units of difference between the sizes - anyone know how to do that?

@old prism modify the FOV parameter in your camera component with a timeline maybe... A timeline that you play forward and backward via run button pressed & released events

Hello, how are you? I am developing a Battle Royale (with blueprint) and I have a little difficulty... When I increase the scenery, which I did using the landscape function to more than 400x400, the character does not appear. Can you help me?
coarse lava
.
Short question: Is there a way to hover the camera around with my mouse after I've switched it by using "SET VIEW TARGET WITH BLEND"? Basically I'd like to "possess" (only the...) camera which is inside a blueprint actor I've made.
Explanation: I made this blueprint for a crypt where the character can hide... In reality the (invisible) character doesn't hide anywhere but instead he, right now, just blends into the other camera while standing next to the grave (and that's just fine). What is not fine is that I'm pretty sure the mouse cursor is still effecting the camera of the invisible character standing next to the grave and not the "hidden view blend camera" inside the grave. Is there a way to "possess" this camera or is it bound to be locked into view?
astral granite
do you want to leave the camera still? if so, you have to see it and the camera has the settings for standing still, disabling the Yaw / Pitch / Row options
@coarse lava changing the subject... I am developing a Battle Royale (with blueprint) and I have a little difficulty... When I increase the scenery, which I did using the landscape function to more than 400x400, the character does not appear. Can you help me?
coarse lava
No the camera is already frozen after blending the camera to another with the "view target with blend". What I want is to unfreeze it. Was going to add restricted angles to the mouse but first I need to get it moving.
astral granite
this is a problem with the view target with blend class, the configuration itself does not allow it.
coarse lava
What character doesn't appear? Your player character? Have you checked the location of your player start node? If you don't have one the player will just spawn to 0,0,0 or something I think.
astral granite
Yes. I use a player start, because is a mutiplayer.
coarse lava
So the character does not appear where you have your player start? I haven't done multiplayers so I don't know much about those but seems weird that your character would not appear if you have a player start set and if it's not being occluded by anything.
astral granite
Yes, i
I think so too, but everything is defined
@coarse lava returning to your subjec.... this is a problem with the view target with blend class, the configuration itself does not allow it, already happened to me.

Hello, I need some help with my blueprints
When I launch the game, and left click(Input action fire), my game freezes and I have to turn off unreal
My Projectile is a simple blueprint, with one cylinder inside a texture on it
When I unplug the spawn class, unreal engine turns off my game and gives me an infinite loop error, which is true, but I dont know how else I could achieve a Hold and continuesly shoot function
thin rapids
so basically, you need to add an delay between the shots, otherwise there's an infinite loop that the computer struggles to run smoothly resulting in a freeze
wide portal
Ooh right, forgot that, true
But even with a delay at the end, the result is the same
thin rapids
hold up, let me recreate that and see whats the issue
because just looking at it makes it confusing to figure out wheres the issue
wide portal
Thank you
thin rapids
try doing it like that (you don't have to remove the connections from the spawn actor and the set physics linear velocity, i just didn't fill those connections)
thin rapids
that's just a guess though
wide portal
Still crashing

hmm... 🤔

i have a Cube with a texture now under my player but everytime he is moving, the texture getting a blur effect

trim matrix
With your and the community‘s help sure 🙂
Saved me a lot of time searching on google for that or watching hours of videos 🙂
thin rapids
and the game stops when I press left mouse button, warning me about infinite loop
@wide portal so, the thing is, it's not doing any instructions other than a loop, so it IS an infinite loop because it's doing nothing else than the loop, ignoring the delay because its not really an instruction
Saved me a lot of time searching on google for that or watching hours of videos 🙂
@trim matrix 😄 awesome!
wide portal
Putting something like output string between then would work?
thin rapids
i think so, the crash may also be an engine bug
wide portal
hmm
I put the string there, it crashed, but for a second I saw billion hellos outputted
Maybe Im using the loop node wrong
thin rapids
maybe the while loop is just completely ignoring the delay and only doing the rest of the stuff you put in the connections
wise jewel
hello
i need to understand a thing
from level blueprint i can get a reference of an actor in the scene
wide portal
Omg I just realised whats happening.
thin rapids
Omg I just realised whats happening.
@wide portal what was it?
wise jewel
but from inside actor bp for example i can't.
thin rapids
but from inside actor bp for example i can't.
@wise jewel yes, the level blueprints are used only to do things that are specific to that level, meaning that theres no way for you to reference a level bp from another class
wide portal
Since the program computes everything and then outputs a frame, What an infinite loop does is "As long as I hold left click, keep computing the loop" but then never outputs a frame
I should try to use Event Tick instead!
wise jewel
mmm
no i mean reference an actor inside another actor
if i select an actor, and in level bo right click, it shows up "create reference.."
thin rapids
I should try to use Event Tick instead!
@wide portal so, the while loop ignores the delay and makes an infinite loop for whatever reason
wide portal
No
It does wait
But that still counts as an infinite loop
cause it includes that wait in the ecommand before rendering a frame
thin rapids
yes, so the delay is useless @wide portal
wide portal
realised
thin rapids
realised
@wide portal did tick work?
wide portal
Ima bout to try
thin rapids
hopefully tick will solve your issue
wise jewel
i mean this..
i can only do it in level bp.
sorry for interrupting the conversation
thin rapids
no i mean reference an actor inside another actor
@wise jewel you cant reference an actor like that inside another actor because that is not a level specific thing, you would need to cast to that other actor you want to reference.
wise jewel
ok
and.. level blueprint the bp of the current map, or level, right? but it's not accessed like any ohter blueprints
thin rapids
just keep in mind that you cant cast to an specific object in a scene, but to the class as a whole
and.. level blueprint the bp of the current map, or level, right? but it's not accessed like any ohter blueprints
@wise jewel yes

apparently cameras are a player controller thing.
when it possess a pawn, it looks for a camera on that pawn and uses that.
or better, is uses the setting of what's specified on that pawn camera.
and in each actor (or only pawn, can't remember) there's a couple of options that specifies if they should pass the camera they have or not to the player controller camera

characters set to 'navmesh walking' mode tend to walk into walls and don't respect the navmesh bounds accurately, any way to fix that?

try them in just walking mode not navmesh see if that helpps

The boom was indeed off a bit, so I reset the positions of both camera and boom, but no win yet

it is cheaper but doesn't support some of the finer checks
@mild pine are you rotating the camera or the boom?

@ocean radish At the moment Im just doing an Add Controller Yaw Input to my Input Axis LookLeft/Right event.
But yeah, the camera is attached to the boom

@mild pine so best thing would be do somthing like a freelook mode, so hold a button and can look around without steering your character

Hmm, strange thing is I've seen games pull this off though, but yeah... even ALS or the third person templates dont come with this, and theres little specific threads about this specific issue
Hmm I'll sleep on it; maybe a freelook mode is the way to go indeed, which would be triggered by aiming with a bow or weapon etc. Any suggestions on how to make that work? Upon input action rotate the camera boom towards the rotation angle? ... uhm yeah. Too late for me haha. 🙂 Thanks for the help so far

@frozen spear sorry for late reply. No, I mean making my own custom editor widgets for the editor (say a custom button I can click), but applying it to each row of a data table.
@frozen spear Not sure if custom editor widgets are even capable of being that integrated with data tables, so was curious if it's possible.
The example I gave was say I had a data table of this structure: [First Name] [Last Name] [Gender], [Custom Editor Widget]. My custom editor widget would be a button. The editor widget, when clicked, would randomly select a first name (based on gender) and last name. Again, easier ways to achieve this without custom editor widgets, but was delving deep into them and couldn't find a way to add a custom editor widget to a structure for my data table to make this scenario possible.

You get a reference to the actor like this and promote it to a variable which is "SmallPP reference" for your case or w/e you wanna name it. Then you can just do a "Get smallpp reference" and drag off and call the custom event off that.
drag off the get and promote to variable and if it saves it as just an actor, you can go in and specifically set the variable for smallpp reference to small pp and then redo the get and connect it like so
tribal axle
Ok, so Get copy, promote to var and use that for all of the targets?
chrome dust
yup then just use that promoted variable to drag off an call the events in the actor blueprint

Wait, so the variable, the references the pp is set, and I call an event in the actor blueprint, the blueprint has all the code for spawning. So I'm not really following ya.

So start the portion I showed you off the "Event Construct" node then go back down to button put a get small pp reference and then spawn it

Dynamic Sort of Item Struct? You mean Sorting an Array of Structs based on some value in a StructMember? @trim matrix

well the specific problem I am trying to solve is having an item struct that can be any type of item (consumable, weapon, etc.) and based on it's type it has a "subtype" enum of that type, f.e. a consumable type enum or a weapon type enum.
I think for now I might just go with a byte
probably will try to come up with a different system in future projects that might have structs for each specific type and maybe also different structs with different information depending on the use case (inventory widget, use/equip, etc.)

Well while you can inherit structs in C++, you shouldn't handle it with Inheritance the same way (as in saving a child struct in a parent struct variable).
trim matrix
there is also the possibility of splitting static and dynamic data into different structs
surreal peak
Cause you can't just cast structs back and forth
trim matrix
yeah I read it will cause crashes
surreal peak
You can static_cast them, but at that point you need to be 100% sure that the struct is of that type.
Not the safest thing to do
You can always use DataTables and DataTableRowHandles to ref different meta data in your items
trim matrix
problem is I also need a blueprint implementation
surreal peak
Yeah then you need to stick with one Struct class
And Enum with the type and/or having the custom data in DataTables then
So the main Struct class holds the info that all items have (possibly dynamic data, not static data).
And then you have a DataTable + RowName in it (DataTableRowHandle) that points to the static data that is different per item
For the DataTable structs you can actually use inheritance in C++
So if they all have a Name/Description/Level or so, you can make a base struct for that
And then make custom child structs with info about the specific item.
Then use that childstruct to make the DataTable
Then you don't have to make 15 structs that all have Name,Description,Level, etc. in it
trim matrix
Hmm seems good, only thing is that maybe one could rather use a function to get the data table row with 2 enums, 1 for datatable and 1 for rowname, since I find having the datatable pointer and rowname on the dynamic structs might be a bit too much
surreal peak
There is a type for that already though?
DataTableRowHandles hold both
The DT and the RowName
And give you UI to select it
It generates an EnumDropDown from the RowNames of the selected DT
I wouldn't reinvent the wheel

How do i make widgets that are open stay open if someone respawns while in the settigns

hello everyone!
quick question, i have this array, it contains 10 different locations, im trying to make a 4 cubes to spawn randomly in four of this locations, until now i have been able to make just one cube spawn, how can i tell the blueprints to spawn 4 cubes at 4 of this 10 locations i have?
surreal peak
Well, that's basically the case if you make sure to not put them into the character :D @hybrid hound
surreal peak
Use a Loop from 1 to 4
And call that code in the loop body
Might also make sense to copy the array into a local one first and then removing the index you used, so it doesn't spawn at the same location twice

My PreCalculus is failing me. I have two vectors. One is the location of my weapon muzzle. The second is where my first linetrace hit. I take both of those vectors and run a second linetrace from vector 1 towards vector 2. My issue is that the linetrace is stopping at vector 2 and not hitting anything for some reason. How can I extend vector 2 so that the second line trace will hopefully keep going a few inches and get a valid hit? I've used "Get Unit Direction" and then multiplied by an integer but that throws off my aiming just enough to make bullets miss targets at long ranges.
surreal peak
Well, if you trace from Vector1 to Vector2, and Vector 2 is a hit, then it probably stops exactly in front of the mesh.
dapper kiln
Thats exactly what's happening
surreal peak
Vector2 - Vector1 is the Vector between those.
Length of it will be the Distance between the two points.
Normalizing it will give you the direction.
So you could get Length, Normalize, + 100 on the Length, multiply it again.
Something something.
Or just multiply the resulting Vector by 1.1 or so and add it back to Vector1
Or have a proper distance variable in your weapon that says how far it can fire
fallow magnet
you can use find look at rotation and tgive those 2 vectors it will give you a rotation, then from rotation you can -> make forward vector and then multiply by length of trace you want like 10000
lusty elk
@surreal peak what do u mean by "Might also make sense to copy the array into a local one first and then removing the index you used, so it doesn't spawn at the same location twice" can u explain me this part pls i don't get it!
surreal peak
Well if you grab a random transform from that array, nothing stops it from grabbing the same one 4 times.
hybrid hound
can you put widgets in the playerstate
surreal peak
Is that widget supposed to be visible by just the local player?
hybrid hound
yea
surreal peak
Then put it into the PlayerController
And check for IsLocalPlayerController before spawning it
hybrid hound
when i respawn i posess a new character which removes the widget
if its in playercontroller
surreal peak
Controller != Character
hybrid hound
i knwo
surreal peak
Yeah, your PlayerController will remain
hybrid hound
surreal peak
That will not cause the Widget to go away if you put it into the Controller
lusty elk
i know what i mean, sometimes its spawning one or two cubes in the same spot, i don't get this part "Might also make sense to copy the array into a local one first and then removing the index you used"
surreal peak
Create a function, e.g. "CreateBlockers" (Blocker!S!). In there, make a Local Variable (if you don't know how, please research it). Make that also a TransformArray.
Set that Array with the one you have already. Now you have two arrays, a local one and the original one. Now use the Local one to get a random index, save that index to a Local integer variable.
Then you can use that index to 1. get the transform from the array and 2. remove the element from the array (from the local one, cause I assume you want the original one to stay intact).
That way it can't pick the same transform twice.
hybrid hound
so im using a trigger volume to setup a capture point however i want my capture point to be robust in saying that i want to place it in any level without changing the level bp, but you cant have trigger volumes in an actor bp. ive tried using a box collision but it doesnt work the same way as the trigger volume

I run a linetrace from 1 towards 2. Then I'm trying to calculate 4 by using vector 3 and 2
I run my second line trace from 3 towards 2 but I need it to go a little further to point 4

@surreal peak Thank you so much. I got it working. You refreshed my PreCalculus hahahaha.
raw sapphire
Hey everyone. This is probably a stupid question but I couldn't find the answer.
I have a blueprint that has a variable.
When I cast to this bp in another bp and get that variable, I get the default value even if the value should be modified.
I suspect this is because I'm accessing the class, not accessing the instance (ie any modifications aren't taken into account).
- Does this make sense? When I do a "get X -> cast to X" do I access the class? Or should I get the instance and runtime values (which means I likely have another issue that I'm missing)
- If it does, how do I solve this? Should I make copies of these values in a gameInstance BP

can i change a box collision transorm during runtime in an actor?

How should I go about making a Freelook mechanic in 3rd person that doesn't alter the rotation or movement of my character? On input get the camera boom and set its rotation based on mouse X/mouseY axis value?
I found it pretty hard yesterday to setup this sort of mechanic without moving the actor aswell. My wishful mechanic is not a freelook one, but one where you can rotate view around without affecting the actor

Can you change game mode via blueprint?

at runtime? not sure i'd recommend doing that

@twilit heath maybe you have an idea for my problem. I want to check if a flag is waved

Hi, how to delete a referenced C++ component in blueprint, which was properly deleted from component list and then the plugin was removed from the project. BUT! The Blueprint is still referencing the component, even though the component is not used anywhere in the graph. I have fixed up redirectors in folder and on start of the project it still complains in the message log that it is failing to load Blueprint. The Blueprint can be opened, compiled and works in game. When I open binary file and search for the deleted reference it still exists. Is there any other way to clear such mess?
twilit heath

how can i measure the distance an object has moved in 3d space
for example the x value?
without using time?
basically i wanna check if an object is moved to the left and right in a given time window
deep elbow
store the starting location, store the end location, compare
thorny cedar
i want to stop when i hit the end position
for example after i moved my object 20 cm to the let
do i have to check every frame?
i have an idea let me write it down
deep elbow
i mena it depend shwat you want to do, theres a lot of ways of movign something,. you could run a timer and check if the object X is > or < than it's startign location and then clear the timer once it happens. you could make a timeline if you know exactly what you want to happen, you could run it on tick if there's other logic you need going on, i mean
thorny cedar
i want to have a flag that triggers an event when moved from left to right
or right to left
deep elbow
and its always on screen or just for a specific time?
personally to get the logic going, i would use Tick - eventually you'll move that into somethign else like a timer runnign when the flag is relevant, but tick is fine to prototype - you store the starting location from when the gameplay involving the flag begins, open up the tick and check the current flag location against your stored location with a vector distance node, filter out the relevant XYZ, and then do a > or < float and have events fire from there that will be left or right
thorny cedar
my first idea was to have sth like this
startpos = obj.getlocation
while(timer!=2.0){
if(obj.getlocation - startpos >= x_value)
{
right = true
}
if(obj.getlocation - startpos <= y_value)
{
left = true
}
}
if(left&&right = true)
{
trigger sth
}
yeah i mean, if you're doign it in code then you're asking in the wrong channel, if you are just using that as psuedo code then you're on the right track.
thorny cedar
ofc the negative x value not y
deep elbow
yeah

Hi all, I'm trying to set a countdown timer if a certain boolean is true. so if it is true then start the countdown, if not stop the countdown and reset. Bit rusty can anyone help me out? The countdown is going to be driven by a curve in a timeline and output a float value
thorny cedar
i'm not doing it in code, i just prefer to writet my ideas down in code
deep elbow
well i mean you could just base it off the actors whatever vector then it doesn't care abou pos or neg
ok psuedo, then yeah you are on the right path, just start plugging stuff into other stuff
thorny cedar
i want the player be able to swing flag and start the trigger as long the person picked up the flag
so call it every frame, while picked up?
deep elbow
if you need it to return somehting, you'll need to check often
thorny cedar
i was just worrying about all the ticks that happens while my timer runs
but i just can lock it with a boolean right?
and set it to false, when my timer end, so my tick starts a new check for swinging the flag call
deep elbow
if you use an actual timer you can clear and invalidate when you dont need to check
start teh timer when player picks up flag, destroy timer when you dont need it
try looking at timer by function, then you can choose a low looping time
if you are worried about ticking etc
but honestly there is nothign wrong with tick, just dont start with it enabled
deep elbow
you can go into class settings on your BP and disable tick from start, then whatever trigger event - pick up flag etc - can enable tick on that BP
yeah thats the right one
thorny cedar
thank you for your help 🙂
deep elbow
you can either create a function with that name, or create a custom event and call it the same name as what you entered in the function timer etc, np good luck!
thorny cedar
@deep elbow one question can i set a timer within a function that im calling?

hi , im trying to set a button that opens and closes a shop when the player overlaps with the collision/overlap area of the shoopkeeper, and i've managed to open close the shop, but i don't understand why it opens from anywhere on the map, not only when i'm overlapping , any idea why this is happening ?

@thorny cedar yeah you can set a function wherever you want

if i wanted to control the rotation of the camera independently of the character, i should rotate the camera i've set on the character right?
i'd have to separate the controls for rotating camera and char

@analog lintel make a boolean 'isOverlapping' and make it true when you're overlapping and make it false on an event 'onEndOverlap' (i think thats the name)
and make it so you can only open the shop when that boolean is true
analog lintel
Oh thanks @thin rapids it works!!! 😄
thin rapids
you're welcome!
analog lintel
Btw @thin rapids why is it, it doesnt work only with the binding the button with the overlap event?
thin rapids
it's because that event can only happen once the overlap event happened, if the overlap happened and you get outside of the overlap area, it will still count as if you could do that event
if you make it so you can't do that event when you leave the overlap area, it will no longer understand that you can do that event when you leave that area
thin rapids
you're welcome! 😄

You can set it that way or decouple the camera from the character orientation.

actors have to be spawned in the world. You can use objects if you want a blueprint without a transform

@sleek jacinth That makes sense, and since I'm new to UE, I'm probably going to ask a stupid question: can I still spawn UObject in the world, later on? Because I'd need to instantiate an object and at a different time, get it to show in the world
