I'm having a bit of an issue with On Component End Overlap event, it triggers when physical body is colliding with the trigger component (as intended), however is player (or another physical body) will step on top of that trigger, after exiting the trigger area On Component End Overlap will trigger, even if there's another physical body colliding with the same trigger component
So what happens, when simulation starts, the cube falls down hence triggers the On Component Begin Overlap as intended, but if player will step on same button, after player will move out the way it trigger On Component End Overlap even if that cube is still here
nocturne remnant
@scenic mesa On your actor spawning the projectile, make sure you put a reference into the instigator. On the projectile, uncheck Initial Velocity in Local Space. Set Initial Speed to 0. Set Max speed to whatever maximum you might want. Put this in the projectile constructor.
Obviously, you can use a different variable instead of breaking out the X velocity of the projectile, but that's what I grabbed out of the default first person template.
I couldn't figure it out at first because I forgot that the initial speed setting will override the velocity even if you aren't using Initial Velocity in Local Space.
@trim matrix You need to actually check what actor ended the overlap
trim matrix
Well, player as expected since it was last to step out of the trigger area and cube is still in there
nocturne remnant
Actually, I guess what you want to do is a get overlapping actors and see if anything is still there
trim matrix
So what would work in my case would be something that is dynamically checking if sphere collision is overlapping with something, not just upon other actor entering or exiting that area
Hmm, that could work, thanks for the hint
nocturne remnant
Yeah, when it ends, just call that and check the length of the array it returns

those things can't happen at the same time, you need to decide in which order they will execute and connect them that way

Has anyone had issues with 4.25.3 and the clients disconnecting from the server on match start? Using Advanced sessions, everything has been running great until the update. now (using two standalone windows), once leaving the lobby and loading the match, the client drops back to the main menu with a lost connection. I even just migrated my whole project to a brand new one just in case. Everything is up to date, and this seems to have started after the .3 update. I don't even know what to look for since I've never had an issue with a client losing connection. Anyone got any suggestions?

hello, i am just starting to make games using unreal engine, and i have watched the 2017 video explaining "multiplayer" replication from the unreal engine youtube channel. I can't help but notice that if clients shoot, the projectile just shows up low to the ground with no Y direction( so it just goes in a straight line forward low to the ground) can anybody help me?
zealous moth
@minor sand that video is a dud and the comments will say so; look up other videos on FPS multiplayer shooters
before you even begin with multiplayer, learn what a client system is and how to work with it because even if you do manage replication, it is useless without a client system like EOS and such
minor sand
yes.. but i can't find stuff i understand because either they have set up a complete game from scratch which i won't now how to start. OR they have flaws like above.
zealous moth
start over; consider that official video a dud on what NOT to do and practice
torpid linden
you really don't want to set up eos or steam to learn about replication, and you don't need to
you can work just fine connecting by ip
zealous moth
you can youtube search several, just make sure they have a beginning and an end; again if you just started out, multiplayer is not my thing, i make single player games
torpid linden
I'd start with cedrics networking bible
which will explain the concepts and ideas
zealous moth
^ bad idea, Cedric's guide is advanced, he just started
torpid linden
if he can't handle this he certainly can't handle EOS
minor sand
i see that i know some things in the bible.
torpid linden
anyway, if you don't understand it then start with more basic stuff about UE in general, like the classes at the unreal online learning
minor sand
and i think il get it if i have enough time to read it all properly. but yeah
torpid linden
and come back to multiplayer when you do understand the info in the bible
it's possible to make a multiplayer game using blueprint only but you are much more limited in what you can do and what you have access to so expect to need to move into C++ eventually
minor sand
anyway, if you don't understand it then start with more basic stuff about UE in general, like the classes at the unreal online learning

Is it possible to have multiple Timelines running at the same time?
For example, player does damage to an enemy by hitting it a few times. Each hit pops out floating damage text (like "-50" damage). I want the trajectory path of the damage text to be random (like going up and then down like an upside down parabola).
I was thinking of having each damage text trajectory path be determined by its own Timeline, but then they'd have to be running concurrently

@nocturne remnant I might be mistaken and am doing it wrong, but you are just grabbing the velocity of the actor that spawns the bullet(instigator) and then multiplying it by the bullet's velocity(Which is default value of 0) and then setting the result as the bullet's velocity?
I tried your suggestion, and if my char is stationary, the bullet spawns and won't move because both the instigator and the bullet's velocity is zero. The bullet only moves the playerChar is moving?
mighty sinew
also is their a default text for it? it asked for one but i dont have one

Hey folks. I'm trying to understand something. I've made an array of Hexes, and I've set up a click function so that when I click a hex, it adds a mesh at the click location. Now, what I'd like to do is make it so that when I click a hex, I get its ID in the array. Right now when I click it, I just get -1 on any hex, and 0 if I click empty space. How can I get it to give me the index of the hex I clicked?

I see the description part, but that only shows the tooltip if you hover over it in the functions area on the left. I'm looking for something to be on top of the node itself.
untold anchor
right click the node, and add comment
you can add comments so sections of nodes and individual nodes
hard kettle
@trim matrix I would first strongly suggest making a hex class, this will allow you to add additional information, such as terrain type, and if you follow that path, suggest storing the index as a variable of the object
flat raft
@trim matrix Making BP Class would be very beneficial like PharingWell stated. If you would like to do it with your current setup, you would have to loop over each item in your array, get the ObjectName, and compare it to the HitActor ObjectName. The match would be your index. Use a For Loop with Break.
Will definitely be slower depending on the amount of hexes you have.

Im trying to do lean when i look over. Everything works except 1 side

also character rotation skips over some degrees too
ik i did it wrong but im not sure how to make it better
flat raft
What kinda lean?
native plover
no i didn't fix it
just saying leaning doesn't relate to the problem it's for context
the issue is the rotation
im not doing it right
here
flat raft
Got a screenshot to illustrate your problem?
native plover
do u not see it?
flat raft
I see
native plover
cool
flat raft
Can I see what ur character is doing? like a vid
flat raft
Doesn't play the animation?
native plover
ye
because its not meeting the condition
that i posted
because camera rotation can't reach the needed view min
flat raft
Ok...so your on a wall...
When you look right, the right hand comes down and u can see behind you
When you look left, you can't rotate any more..so the left hand doesn't come down and you can't look behind you.
is that the issue? Looking left?
flat raft
You're using the camera rotation, have you tried using Control Rotation?
native plover
look at the numbers on left
orange must be close to blue
but range is too off
You're using the camera rotation, have you tried using Control Rotation?
@flat raft it's the same
the math is wrong
idk different way
flat raft
Your camera is straight up locked on the left side
native plover
?
flat raft
you have limits set on how far the camera can rotate?
native plover
yes but that's not the issue
it's supposed to release the limit and do animation
like on right side
flat raft
yea yea.. looking at it.. hmm
native plover
it's adding and subtracting is the problem
because it goes over the limit
but that's how i track the rotation so idk
native plover
ok
flat raft
When your character is on the wall... say the yaw is 0
So u have in ur screenshot get actor rotation..
native plover
mmk
flat raft
When ur character is looking straight ahead, ur camera rotation also is zero
native plover
eh ok
flat raft
Then you set the limits...
Say your character can rotate his head 90deg +- before the animation kicks in
So you min would be the actor yaw -90, and max is yaw +90
anything larger than that would trigger your hand letting go animation
So your min is going to be GetActorRotation.Yaw - 90 and your max is GetActorRotation.Yaw + 90
native plover
how would i 0 rotation ?
flat raft
well... try that first.. disconnect the unlock part in ur bp.. and set up the math so that your head locks to your range
flat raft
That's good... now... disconnect the pin after ur set max
flat raft
Exec
native plover
yeee?
flat raft
Your going to say... if camera rotation yaw is greater than the min... print "greater"
if camera rotation yaw is less than min... print 'smaller"
native plover
i did that before this i meant to say
flat raft
ok... try again.. let's see what happens
Basically as it crosses the min max threshold, it should print something
native plover
ye
it's the same thing as nearly equal
nearly equal works better
i did do your way i remember now
it's the same result my way just does it smoother
flat raft
Nearly Equal is not a clamp.. say your nearly equal is 90deg, and you are rotating .. the value can be 80deg, 85deg, 87deg, 92deg, 95deg.. depending on ur tick. So u can miss the threshold. Try a bigger tolerance if ur want to use nearly equal
native plover
tick is on every mouse input
flat raft
If I turn the camera really fast, The tick will register yaw at 80 and the next tick 100.
Since ur nearly equal is 90, it will miss the trigger
flat raft
Must have a nice machine.. lol .. mine sucks
flat raft
anyway, did you try it? does it print outside the range?
native plover
yes but it's twitchy that's why abandoned that approach it's not smooth at all
flat raft
ok try nearly equal with a bigger tolerance maybe
native plover
again check this https://i.gyazo.com/6b91728f23a9bf7bc49b11a9eef8b7ef.mp4
look at numbers
it's big difference
native plover
it's the same
both approaches use the same data
changing the condition doesn't help
flat raft
but the branch way works, it's just choppy?
flat raft
hmm
native plover
u wanted like that ?
i made it so right doesn't work
so don't worry about the min
flat raft
Ok.. so when it is greater than .. nothing prints?
flat raft
It's should print true
native plover
ya...
flat raft
it's not printing true?
flat raft
Hmmm.. print ur actor rotation yaw
native plover
number ?
flat raft
yea
native plover
without the - and +?
flat raft
It's should be constant number as u just hang there
native plover
it is
flat raft
what is it..
native plover
it is constant
flat raft
what number?
native plover
171.5
flat raft
What's ur max set at?
flat raft
Right.. as soon as ur camera hits 247 it should print true
flat raft
the max of what?
native plover
camera rotation
flat raft
oh you stopped it at 180?
native plover
it's default 180 XD
so is actor rotation
but we are adding to the actor rotation max view
so camera rotation can't get to that value
flat raft
wait a minute... you have limits on the camera?
native plover
view min max are limits if that's what you're referring to
flat raft
no no.. this aside..
native plover
well besides that there are nothing else
flat raft
when ur character is standing normal, and ur are looking around.. do u have a limit to how much ur camera can turn?

so when it's above 180, you can't do the animation

nothing i wanted you to see the angle that doesn't work

if you're facing that direction it won't work
m8 walls are not always same rotation
@flat raft
it changes depending how u placed it
flat raft
trust me.. when you are on the wall... in any direction, it will work. It will work because your character is still.. and the camera is rotating
give it a try.
native plover
if wall is facing you at above 180 rotation from your character it won't work
dude you have the same system as mine
nothing to try
you try
face the character in that direction

when the character is standing, the mesh moves with the camera

so the math is different. When you are on the wall the mesh is still

but rotate the actor to the side where it's above 180
and separate the camera again

maiden wadi
@mellow wadi I'm not sure why your function doesn't work. It looks like it should. I tend to just create an empty variable of the widget type and on call ask if it's valid. If not, create the widget, populate the empty variable and then just remove/add it to viewport if the variable is valid. Makes it a little easier than keeping up with extra booleans and since you are basing it on whether the variable is valid, if it ever gets garbage collected for any reason, it'll just recreate it.

I have a door actor and it has a static mesh and a box collision
The door should rotate 100Β° when the player overlap with the box and press "E"
It works fine but i noticed the box is rotating with the door and i want it to be static. But when i edit it to be static the rest of the components are static. How can i set different mobility options for each component of the actor?

@sly finch You should create an actor, the base component should be the box collision and it should have the static mesh attached to it. On Actor overlap or Box Collision component overlap play your timeline or whatever you're doing to rotate the door.

@tough ore Casting does not 'get' anything. Casting simply changes a reference's type. Note I said reference and not the object. If you have a Character, which inherits from Pawn which inherits from Actor, A spawned Character can be referenced as an Actor, Pawn or Character. A spawned Pawn can be referenced as an Actor or Pawn, but not a Character. Casting is when you have an Actor type reference for.. in this case say a Character. You can cast that reference type from Actor to Character. In your case you need to use GetGameInstance and cast it to your game instance.

Hey all, I'm running through the book "Unreal Engine 4.x by Example" by Benjamin Carnall. The book was first published in 2016 so I realise he would have been using an older version of unreal than me...
I've followed the instructions to the letter and have run into a problem, and I'm not sure if it's me or just because I'm using an updated UE4. Could someone help out?
Here's the blueprint from my Game Mode
...And the second error I had just suddenly fixed itself when I recompiled to take a screenshot. Β―_(γ)_/Β―
I found that someone else had a similar error back in 4.17/4.18 and that turned out to be a bug https://answers.unrealengine.com/questions/714268/signature-error-binding-to-onperceptionupdated.html

Hey guys I'm trying to measure the time the moment you start to tilt your left analog stick to the point you made a full tilt but couldn't seem to get it right in blueprints.
Check this out
Can sum1 plz make a suggestion on what I did wrong with the code based on the red circle?
another way of explaining what I attempt to do is I want to retrieve the scale value the moment I tilt my analog stick; if the scale value is greater than 0 but less than 0.9 start the timer.
if it returns to 0 or surpases 0.9 stop the timer, but as long as it stays within range continue counting the timer.
and print out the time in seconds or milliseconds.
maiden wadi
@undone tusk Usually you can solve that with a recompile. If that doesn't work. Try selecting each node starting with the red Event node and bring up the menu with right click and select "Refresh Node".
@proven mason You just looking for the amount of time it took someone to move the analog stick from the center to the very edge?
proven mason
yes
undone tusk
@maiden wadi That did it! Thank you!
maiden wadi
@proven mason You would need to create s bit of checking logic after the axis input. I don't really have much good advice besides a bunch of logic checks. Something like this might do the trick, but I threw this together pretty quick. Dunno if it'd bug up or not.

I need range on Timeline but how can i get range ? Im gonna connect range with field of view
maiden wadi
@plain flare If you mean the distance from one actor to another, you either need to get their world location and vector math it, or do a line trace to find the other one.

Anyone know if the "Time" param of this USplineComponent node is meant to take the "Time" param as a range from 0.f to 1.f? It's peculiar that they'd call it "Time" if so
sand shore
It is, the rationale is that assuming a constant rate of progression, it is the ratio of time spent traversing the spline

@sand shore thanks for that explanation. Could you by chance articulate what bUseConstantVelocity adds when true? I understand that it assumes a constant speed, but the definition of Constant Velocity in textbooks is that it also assumes moving in a straight line. The confusing part for me is that my spline has all kinds of curved points on it

im currently trying to get a health bar working amd im at the step where you create a binding via the display percentage and when i drag off and search for "third person character" nothing comes up
maiden wadi
@trim matrix Do you have a character class with the health variable in it?
strange pike
can anyone help me with a small problem i have? i keep getteing accessed none for a vector varible
trim matrix
@strange pike have an isvalid check to make sure the variable is not null when accessed.
@maiden wadi yes
strange pike
example? @trim matrix
maiden wadi
@trim matrix What is the class name for your character and is this character controlled by the player's controller?
trim matrix
@strange pike https://docs.unrealengine.com/en-US/BlueprintAPI/Utilities/IsValid/index.html you can search for isvalid or accessed none via search.
@maiden wadi yes the character is controller via a blueprint class FPSController and i have another sepretae blueprint called HealthBarHUD
maiden wadi
Try to Get Player Character, cast that to your class with the health in it.
mellow stump
right click and type it
trim matrix
wait
do you want me to do get player character in my health class or my fpscontroller class cuz it shows up in my fpscontroller class
maiden wadi
This will get the health of the character class that is currently being controlled by the current machine's player controller.
trim matrix
oh ok
maiden wadi
Well, as long as you have those two variables it will.
trim matrix
what do i type to get the cyan color block
make sure the heatlh variables are exposed in the blueprint too
maiden wadi
Why do you need to expose them?
trim matrix
if he wants to access them outside from the node pins, not necessary if it's just a cast i suppose.
https://www.youtube.com/watch?v=qzcqmVcV9IQ skip to 5:40 thats the part that doesnt show up when i drag off and type in
maiden wadi
Exposing is meant for the spawn node. To change them as the actor is being spawned. Instance Editable is for changing placed instances' variables in the editor. You shouldn't need to do either to access variables at runtime from your coding or blueprints.
trim matrix
yep not necessary, i just sometimes have a practice where i expose vars because i often use the Spawn node.
maiden wadi
@trim matrix In your content browser, what is the name of the class that has the Health variable in it?
maiden wadi
No, the class that you're trying to pull the health variable from, the actual character class.
trim matrix
that would be FPSController i believe, sry im new to unreal and coding this is my third day
maiden wadi
The health is in the controller, not the character?
trim matrix
no
@trim matrix here's how i do it
the variables i have in FPSController are Current Health, Max Health
i use interfaces
does that work for normal health bar lol?
seems complex
mellow stump
c++ is complex
maiden wadi
@trim matrix
trim matrix
@trim matrix you are correct, interfaces are advanced and you can probably do it Authaer's way
maiden wadi
Try that one instead. I thought your health variables would have been in the character class.
trim matrix
ok
@trim matrix this way uses direct connects
get owning player pawn, cast to the asset that has the variable, and then get the variable by dragging off.
no interfaces needed this way.
ok ill try both
cool
once again sry very new to this, the only coding program i have used is bare minimal of C++ and Python
maiden wadi
Interfaces are fine, but I don't think I'd ever use them in a binding. They're somewhat expensive compared to just getting the variable and on every frame it's a bit unnecessary.
trim matrix
@maiden wadi you think it might be adding to my tick time? i do want to take all steps to minimize cpu utilization for my game.
simple crow
@trim matrix I just made a new level and now they stopped working again
I have a nav mesh bounds and didnt change any code
trim matrix
'FPSController' does not inherit from 'Player Controller' ( Cast To FPSController would always fail).
maiden wadi
I doubt it's enough to care over. Just performance habits on my end. I try not to use interfaces unless I'm dealing with different classes that don't have a common base class. UI designers get a lot of leeway with performance a lot of the time.
trim matrix
did you assign the same controller as your other level
simple crow
yep
maiden wadi
@trim matrix What is FPSController then?

Hello, I wanted to ask about Level Streaming. Is is worth to split Landscape into like 5-10 sub-levels, big chunks, each containing a whole town.
Or hundreds of small sub-levels, that would contain every building interior in separate map and etc. How it will affect level streaming system? Will it work slower?
maiden wadi
@trim matrix Ah, FPSController is actually a character class, I can see it in the top of your screen. It's a Character and not a Controller.
trim matrix
yea
simple crow
@trim matrix when I print string from the movement result it says it was aborted
maiden wadi
@trim matrix The first one I posted earlier should have worked then. Try this.
maiden wadi
Try what I just posted. GetPlayerCharacter, drag off of it and start typing FPSController, it should show up as Cast To FPSController
trim matrix
@simple crow maybe you ai is being spawned in a bad position or something
simple crow
k wait
I dont think so cuz they spawn fine and shoot at me they just wont walk around
trim matrix
@maiden wadi nothing shows up
just print string is destination vector and see if it makes sense or check is actor is valid

trim matrix
your input to the moveto function
simple crow
ah ok
maiden wadi
@trim matrix Do you have the GetPlayerCharacter node?
simple crow
it said it was valid
simple crow
ah k
trim matrix
@rich trellis unreal is meant to handle level submaps in large chunks. as you can see from my output there, i have 3 chunks of submaps for my level. each one is fairly large with many trees and grass meshes. this way, you are able to optimize larger areas and texture them. unreal was always built this way for large chunks as optimized,
maiden wadi
@trim matrix Right click in an empty part of the graph and type GetPlayerCharacter, get that one first.
trim matrix
ok
simple crow
@trim matrix it says sucsess when then cant see me then when they can it says it was aborted
trim matrix
got it i was in the wrong place lol
so that means the location doesn't work for the ai
paste ur code
now what @maiden wadi
simple crow
it is the same as before
trim matrix
sec
simple crow
that going into the moveto
strange pike
@trim matrix its returning as null
trim matrix
show the aimoveto node lel
simple crow
@trim matrix
strange pike
its returning as null
code
trim matrix
@strange pike you have to make sure wherever your receiving your vector, it's passing the value. the isvalid check only checks if its not null and then passes it preventing unreal accessed none warnings.
so basically, if you are trying to pass the vector, make sure the values are supplied correctly.
ok one moment i'll take a look
image is a but blurry, but
i cant read the reference to the left of the GetActorLocation, but whatever that reference is, it's not valid.
maiden wadi
@trim matrix Drag off of the GetPlayerCharacter and Cast To FPSController
trim matrix
so make sure the reference exists at runtime
@simple crow are you playing as the first person character?
simple crow
@trim matrix yes
trim matrix
it doesnt give me and option to cast to fps controller ffrom dragging off of the get player controller
mellow stump
dont drag off then
trim matrix
try getting your actors world position and plug that in the vector instead or anything for that matter and see if the ai goes there
mellow stump
just right click and type
simple crow
nope
mellow stump
dragging off wrong things may not give the right result
trim matrix
ok i got it linked to the object port attached to cast to FPSController
maybe try this node for the pawn
@simple crow
you're using the right controller for the ai right
i don't know where your logic is for the moveto function
now what do i do?
simple crow
@trim matrix what logic? The ai is just running at the player
trim matrix
what class are you in to preform the logic "run the move to task"
you're in the controller?
of the ai?
anyways try doing this node for the target
so thats all the help i can really offer not sure I'm not that experienced
sand shore
@sand shore thanks for that explanation. Could you by chance articulate what
bUseConstantVelocityadds when true? I understand that it assumes a constant speed, but the definition of Constant Velocity in textbooks is that it also assumes moving in a straight line. The confusing part for me is that my spline has all kinds of curved points on it
@snow halo Constant velocity means that if you lerp from 0 -> 1, the point along the spline will progress at a constant rate in world space. The time input would no longer be normalized fully, in other words. I don't really think I'm the best to explain this.
That being false allows you to get to halfway along the spline with .5, but depending on how you outline your points that may be visually .85 of the way through?

I ended up with a weird problem; I added a few new variables to my Item object, and it ended up breaking the Item Pickup process. I tried to re-save and re-compile everything that used Items but it still destroyed item actors without adding them to inventory. I traced the issue the 'empty item' used to find the first empty slot, which apparently needed to be deleted and replaced followed by a new compile.
In doing so, a question came up: As it is, the process checks each playable character until it finds one that has an empty item slot and adds the item to that slot, but I also thought about saving the item slot number in the search for the character who will acquire, and then casting to the First Person Player to get that slot and fill it with the item.
Which of these methods is better? I tested both of them to work but if one is more resource efficient I will use it

Someone had a plugin that hadn't been updated for 4.25 that put in blueprint nodes that used the quat stuff. Looking at the source, the quat math stuff is all in there... it's just not exposed to blueprint.
untold anchor
i think i know of which one you're talking about, it's a c++ thing right ?
and then the plugin is supposed to allow blueprint exposure
i was considering it
but, this method provides solid enough results that i'll avoid it for the time being lol
nocturne remnant
But all of the actor specific functions are private class things, so... I'm not sure how best to hook it since I never actually had to learn c++
nocturne remnant
I may actually know where the base level quaternion math stuff is now, which would solve that issue
in a surprise to no one... the source for UE4 is... pretty fucking large.
And you run into things where the header files are in one place... and the actual private .cpp stuff is somewhere the hell else.
snow halo
@sand shore thanks for that info. it all helps : ) I'm about the throw in the towel unfortunately. My ultimate goal is to have multiple splines with one spline as the primary spline. Every object on each spline would line up perfectly with the objects on the forward vector of the primary spline
untold anchor
i did not allow for running in inverted surfaces though, as my game won't need it
snow halo
If anyone could solve this for me or with me, happy to pass a couple hundred $ : /
nocturne remnant
Yeah ... parts of it are totally straightforward... here's the public directory with the headers... here's the private directory with the c++... And then there's shit that's up a directory, and down two directories from that. ripgrep has been pretty useful because it's stupidly fast
untold anchor
however i may impliment it just for the sake of having it is suppose
sand shore
Unfortunately, I'm going to have to pass on the offer
snow halo
As long as the primary spline is straight, i have it working already
sand shore
I can put out a feeler to see if someone I know is free tho
nocturne remnant
Did you at least put some of your linetrace stuff into functions? I remember you having a few that were doing the same thing
snow halo
but if i curve the primary spline with multiple points and moving tangents, things stop lining up
ya i'd really appreciate that
untold anchor
not yet, but I will
snow halo
i imagine it would take someone knowledgeable an hour or two tops
untold anchor
i tend to lay it all out, first
snow halo
if not i'll pay more : P
nocturne remnant
also, I wasn't sure if you were building something specific or just "problem solving"
untold anchor
free flowing and all that jazz, then make it cleaner
yea, i'm building something specific, but when in the problem solving portion, i just leave it all out nasty XD
nocturne remnant
Yeah, I'll do that too sometimes... throw the stuff out there and then collapse it later. It super sucks for anyone else looking at it because you'll know where things are "geographically" but they don't
snow halo
just need those ISMs all lined up
untold anchor
yea, it'll be nice and tidy in the end though
sand shore
following the curve of the spline?
untold anchor
i've started from scratch on this whole character like 10 times just due to the wall running lol
snow halo
the objects follow their respect curves np, but I need all those static meshes to line up on the forward vector of the primary spline
untold anchor
this time i realized the wall running might be the most "difficult" aspect of it, so let me just do that first above all else
and then work within that framework to build the other things
instead of the other way around
snow halo
so if i was big overlap component box running, i would trigger rows of these objects, 1 on each spline
nocturne remnant
I can't even figure out what the hell I actually want to build at this point
snow halo
They allllmooost line up on x perfectly. I'd say i'm a few centimeter or so off at times : / just not sure how to get it perfect
untold anchor
hmmm, i present to you a set of challenges. Have you ever built a skill upgrade system? or leveling up to allow you to upgrade that system? or perhaps items that you can equip that effect the skills in that system in different ways? ^_^
snow halo
and I'm doing it all in c++ rn, but blueprint / c++ all the same
sand shore
if you don't hear back, I don't have a response
snow halo
o course : )
nocturne remnant
Are you talking specifically about implementing it programmatically or are you referring to the actual systems design portion?

any of the above, not sure if you're just looking for concepts to build out and excericize, or you're a project, or what

I created a 'Foliaged Instanced Static Mesh Component' Blueprint which can be used in the foliage editor, but how can I get it to make sounds on overlap? None of the usual nodes are showing up.
@tired arrow You should do that in Level blueprint, or you should make actor blueprint.
Instancing doesn't have to do anything with that.
You make trigger box, and add event overlap--> object--.>play sound--.>
You literally need just 3 things.
tired arrow
Hey so speedfreak I have a lot of bushes
Using collision boxes wouldn't work for my use case, but thank you for responding! You're also right that I didn't need to create a new foliage blueprint. As for the answer it's simple I'm just tired rn. All you have to do is create a new trace channel, set the instanced foliage in the foliage tab to overlap with the channel, then have the player character check for collision with a cooldown on the noise.
tight cobalt
@tired arrow You can create one actor_bp, then instance/copy it throughout the level. All you ahve to do is to place the BP in the loaction of the folliage, thats all. I connected it like this cause it was more convenient in my case.
Also line trace is much more expensive for this, I wouldn't never do line trace to do it.
tired arrow
In my case not having the instanced foliage would give me more of a performance hit than using a line trace. Plus the line trace isn't on tick, only on a .5s timer
tight cobalt
YOu can keep instanced folliage.
No issue with that.
Just instead of tracing the foliage, you gonna check is object (character, bullet,whatever) collided with the trigger box that is placed at the bush location.
tired arrow
How would I automatically duplicate the blueprint at each foliage instance?
tight cobalt
You can make instanced blueprint, like you would do with any other instances.
See my lvl
Green and orange boxes are the triggers for the sound.
You right click the actor_blueprint
and select make child blueprint class
There are many different ways to do this, you can even make only one play sound, that changes everythime depending on the bush. You can do switch on int, or random..

shut hinge
i need to get the leveling component off the tick and onto a timer, but I don't know how to set the timer up for it.
maiden wadi
@shut hinge What's wrong with it being on tick?
shut hinge
This is what I was trying to do but I don't thik I can do it with Validated Get.
I wanted my 9 party members widgets to toggle on and off on the screen, so when you toggle the widgets on or or toggle some of them on, their stats all begin to show up on the screen. (help to clear all the clutter when you don't need all their stats to be all showing) You can toggle one or more party members off.
But The result I'm getting is when I toggle each party member stats on, the party member stats toggle on only on the party member that I possess and does not stay on for the others that I turn the widgets on unless I switch back to that party member again. So the result is alot of empty party member stats with only one party member's stats showing when I turn on all the widgets.
So yeah only one party member's stats show up at a time when I switch to each party member which is no good, all their stats should be showing up when turning on their widgets.
So this Validated Get will allow me to toggle on or off all of the widgets, but only show one stat at a time. So the levelling Component is the problem, its not showing all the stats when the widgets are turned on.
The Levelling Component Code (it currently runs off the tick, I was told I have to set it up with a timer instead to get it all off the tick, that part to implement the timer to it I don't know).
maiden wadi
I'm not at all sure what a Widget not displaying the correct values has to do with switching something from tick to timer.
The timer will do the exact same thing as tick. People are neurotic about not using tick because they think that it'll ruin their game performance. If you have something that needs to happen all of the time while the actor/component is active, it really should go on tick. If you want better performance, lower the tick rate.
shut hinge
LOL no diff in timer or tick... Ok How this was set up to show all different stats of the 9 party membrs was to make 9 copies of the level component and put them on each party member. Othrwise if I used the same one component for all 9 members, I would get the possessed party member's values all duplicating in in all the other 9 party members widgets....That's why I made 9 copies of the component and stored the individual party levelling XP stats in each component.
maiden wadi
How is your widget getting the values to display?
shut hinge
The levelling values are being binded through the Widget Designer. But what I'm finding out with possess pawn, is the widgets stop showing their stats on the screen when switching into different pawns.
maiden wadi
In the widget bindings, you're getting the values from the currently controlled character?
shut hinge
i'm just gonna get the binding now hold on
here's the binding for one of the party members Skynar.
so I stored the level XP values in the component itself.
So when I switch into Skynar his stats shows. But if I turn on another widget then it stops showing skynar's stats and the other widget shows it seems that the possess pawn turns off one pawn's off to turn on another.
When I need all the pawns I'm switching over into remain turned on so their stats can stay up on screen when their widgets are being turned on.
I'm not sure what the solution is to keep all the pawns I'm switching into all turned on, do I need a multi gate?
maiden wadi
You'd have a much easier time with this if you would just keep an array of references somewhere that has all of the party members. Create a single userwidget that has a Name, Health, Level and Icon like you have on each of these. Then create a second UserWidget that has a VerticalBox. When you create the verticalbox widget, loop through the character reference array and create one of the stat widgets for each character and pass the reference into the stat widget to make it update itself. But that's just ease of design. Right now your problem is that you're relying on the possessed character. You need to get the correct reference for your bindings to show their own character's stats.
shut hinge
Well at least I got their XP to only increase up when running around the level...
at the moment. The array of pawns is stored in the player controller.
hold on I gt the code for that to see what I need to do in binding

any way to do an "Is Valid?" check on an interface reference?
its a light yellow color
maiden wadi
@still trellis Not sure what you mean with an interface reference? Can't recall anything with a light yellow color.
still trellis
that bottom one there
its a variable of type BPI_ReceivesDamage which is an interface that i created
i am just calling functions on it, which i can do fine, but would like to null check before doing so
can work around it if its not currently possible, was just curious
maiden wadi
What does that pin type say when you hover over it? Just curious of what it is. It doesn't look like a softobject or softclass reference.
Oh. I see.
still trellis
i see that there is a ToObject(Interface) node, im using that right now
i'm assuming that this is essentially the same as casting something to the interface type rather than its own type, to be used with interface calls rather than interface messages
Apply Damage is an interface function, and this version of it takes an interface reference rather than an object reference like the Message nodes do
weird
there's like zero documentation on this
maiden wadi
Yeah, I'm not exactly sure. I've never used a direct variable for interfaces. I just implement them in the classes that I need the interface in and make message calls.
still trellis
i know the Message nodes are safe in that you can pass them something that doesnt actually implement the interface and it will just spit out whatever defaults for a return value or just do nothing, im guessing internally they do a DoesImplementInterface check or cast to the interface type first, so this is just skipping that step
or i could be totally wrong and hitting play will crash everything π

I was given the code to update widget bindings of the party members, but not the screenshots to the references of these widgets. so I'm having trouble knowing which reference goes where.

hello, is there a way to assign the same blue print to multiple meshes?
shut hinge
how do I bind this event? The designer won't let me bind it.
elfin hazel
Drag off the red square and type create event.
shut hinge
Can't because its inside of a function. It has to be a custom event it has to be binded to.
I know how to bind things in a function with the designer but not outside of it.
This is what is has to do
elfin hazel
well, it won't look exactly like that , but it will have that functionality.
shut hinge
how do i update the widget if I can't do the custom event in the binding of the widget?
elfin hazel
You don't create the custom event in the binding. Drag off the red square and type create event.
gloomy linden
why not make a new function with the shizzle you want and call the function when you need it?
shut hinge
all I know how to do is just click on the Level number in the designer in the widget where my level value is and then click Bind text, and then put the binding inside of the function.
Ok did create event, now Up pops a tiny list of functions.
which one do I choose?
elfin hazel
I wouldn't know. My guess is that you'd want to create a new one for that event, but maybe you have something neat set up already.
shut hinge
I have no idea, I hit create matching event, that now brings up a custom event so I guess I just delete the create event green node and just keep the custom event one. I got no idea what I'm doing and just guessing.
elfin hazel
well the 'green node' is what is linking that binding to the event.
shut hinge
this is much more harder than I thought because if I do create event off that Red squar, I can't create the float pins to the custom event because up pops only options to choose event functions.
elfin hazel
Choosing "create matching ..." will create an event of function with those pins.
shut hinge
the editor was playing up not refreshing the nodes,, it now allowed me to create the float pins, but i got a ton of errors now popping up i get a screenshot to show whats going on
elfin hazel
First of all, custom events goes in the blueprint graph or whatever its called.
The event must have matching properties to the dispatcher, so you can't just add new inputs.
If you renamed the event, you may have to re-select it in the create event node.
brazen elm
Hi, is there a way to refresh all blueprint nodes, across your entire project. I know there is a 'refresh all nodes' on each indivdual blueprint but I need to refresh them on quite a lot
shut hinge
Well I found that the widget is updating its level value through the widget refrence, and not through selecting the level text value itself and then binding it.
shut hinge
is this right? It don't l;ook right.
for I'm having difficulty trying to get this right.
twilit heath
bind goes where the call is, UpdateXPBar before the lower Cast, SetPercent behind SetText, and you pull Percent from LevelingComponent
after Bind, you also call UpdateXPBar manually, one time
shut hinge
I've not done event bindings combined with timers before this is why I've run into trouble.
This is supposed to be a levelling up component for 9 party members. That's why in each of the components I have the party's xp values in them.
What I was trying to do after possessing each party member was to turn their widgets on and keep their stats on the screen as I switching between party members until i toggle the widgets off again when I don't need them. But I can't get that to work. For when I switch, only one of the party members show up at a time when the widgets are turned on. Resulting in this problem.
twilit heath
not surprising with GetPlayerCharacter[0]
shut hinge
So when widgets are turned all, only one of the party members Stats show at a time when switching pawns. Real annoying this is. I've had this issue for a very long time.
twilit heath
never use that function until you fully understand what it does
unless you are doing single player, then its fine
shut hinge
I followed a tutorial to install in the levelling party XP system. That all I could go for because the guy did not show us how to put it on a timer.< SINGLE player is all fine, Party Group it does not work. If the guy who made the XP system had released a third video out to show how to do it for party group systems I would not run into this trouble.
because I need to modify that xp system to work also for party group mode not just single mode.
So I don't know what the solution is to modify his system to work for group party mode. Do the pawns need to use a Muti Gate node or what to keep them on so their stats do not keep shutting down each time they switch.
elfin hazel
Your system is so messy, I don't really know what is going on. But I think that the problem is that you're using GetPlayerCharacter, as well as casting to a specific class. In your own image; https://cdn.discordapp.com/attachments/221798862938046464/739810997040054272/screenbad.png
in the binding, you GetPlayerCharacter, which will return a different character when you possess another character.
Then you cast to your specific character. Which means, the other widgets - assuming they cast to their own character - will fail.
shut hinge
is this get player character index number the same number as the player possession number in
the details panel when you want to possess a certain player, or is it the number to the pawn registration array?
twilit heath
@elfin hazel trying to Bind to an event inside a function that runs every TIck is a horrid idea
elfin hazel
Yes, I know.
twilit heath
@shut hinge its neither
its the PlayerControllers place in the FConstPlayerControllerIterator
its not cached anywhere
so you need c++ to pull the Index out
so that function should only be used if you have only one PlayerController
or you need to iterate over every PlayerController
and in no other case
shut hinge
how do we switch pawns and keep them turned on so their stats don't keep on turning off when you switch over to them
because the levelling component was running off the tick so soon as I switch, that pawn's tick switches off and the other pawn's tick switches on. that's what's been happening.
that's why I can't get all their stats to stay on the screen during the switching. or when displaying their stats all at once on the screen.
which is a shame because I wanted party group screens for my party members and find it only going to work in single player mode.
twilit heath
http://cedric-neukirchen.net/2017/02/14/multiplayer-network-compendium/ read this a couple of times, then use PlayerStates for it
shut hinge
Player States? Oh its not a multiplayer game but is a single party group game. Couldn't do multiplayer, its much more harder than single player.
twilit heath
your answer is still PlayerStates
shut hinge
a;right I will have a look at that. in this doc
twilit heath
or equivalent
you can't use the GetPlayerCharacter[[0]
because its the possessed pawn, always
widget should have a reference to the pawn its displaying fed into it OnSpawn
shut hinge
Ok. So its the player who controls that particular pawn. Because the other issue that happens when you possess that other pawn then switch back is their AI Controller stops working after you leave them. I was running the pawn on AI Human.

How do you cast content from a editable text box to a Scroll box?
When a button is clicked
twilit heath
you don't
dire copper
Is it possible?
dire copper
oh
shut hinge
drat.
this is a valiable document. Handy for multiplayer setup.
ok i looked at the section on player states, I do have a team number system already set up, but not sure how to set it up with this playerstates BP. He does not show the whole set up in his document..
hexed oasis
how can I edit (with editor tools aka move tool) child component that was spawned by the construction script?
say i got array of static meshes that im looping and spawning each one
how can i then select them in the editor and move them?
shut hinge
I think its Editor Widget Utilities. You need to create the widget and menu to allow you to move and edit them. Codelikeme had to do that with his moving meshes around and changing properties of them within his procedural system.
hexed oasis
oof.... I didnt want to mess with it
shut hinge
yeah last time I used it, and removed the spline actor from out of the world then deleted the spline actor in the browser it corrupted the project and rendered the construction script useless for any new blueprints by slowing down the machine to a crawl and causing it to crash when inserting any new nodes into the construction script of any new blueprints. Wow that's what happens when I delete a spline actor from the window browser. epic bug..
foggy sundial
so assuming you have 2 Concentric circles like this
how would you get a random point within the green circle but not within the blue circle
hexed oasis
first get random radius between the 2 then get random angle
then do simple polar to cartesian conversion to get the vector location
or keep it as is if u are using polar coords
thorny cedar
i have a skeletal mesh and an actor that i wanna grab on runtime, can i place the actor on my skeleteal mesh?
foggy sundial
I'm using it to generate enemies uniformly from the center of the map
thorny cedar
i tried it and it always snaps out of it
foggy sundial
wdym by snaps out of it
