when constructing the widget for the first time
#blueprint
twilit heath
use that GetActorOfClass node and plug the result into the extra pin you'll get in ConstructWidget
after that you have a reference to that quest for the lifetime of the widget
gusty shuttle
Cool, thanks, I'll give that a shot
twilit heath
then setup an EventDispatcher in the quest
with 2 integer inputs (CurrentNumber, FinishNumber)
gusty shuttle
For some reason I NEVER use Event Dispatchers, I really should
twilit heath
call the dispatcher whenever either of those change
and in widget, on Construct, bind to Quests EventDispatcher
and in the Event handing it, set the text
gusty shuttle
Nice, I'll give that a shot
twilit heath
you will need to initialize the text too, once, on construct, because dispatcher won't fire just because you bound to it
dusk flame
"Hello" gets printed, so I know the SetScalerParamaterValue is being called.
gusty shuttle
with 2 integer inputs (CurrentNumber, FinishNumber)
@twilit heath I'm looking into how to do this in a dispatcher but there is no way to put inputs in a event dispatcher?
nvm, found it at the top heheh
twilit heath
you just answered your own question @swift pewter
maiden wadi
What do you mean by default value in child classes? They should inherit whatever the parent class is. If you wanted a different default, another widget would have to inherit from that original widget and set it's own default for it's children to inherit.

This node just Straight up kills Unreal engine, wtf...
And I have it in the Construction script of a Blueprints, meaning if I open the Blueprint it kills Unreal
But just adding it to any instancedStaticMesh component in other blueprints kills unreal when it's executed as well, no matter if it's in construction script or while playing

so you need to line trace to get the actual hit location?
gloomy linden
You could use it as start or end location for a trace

So far I managed to get the print outs Standing, Walking and Running when I push an analog button/stick towards a scale of 1
but when I set brake friction factor to 1 and brake deceleration walking to 300 I don't get the print out "Walking"
Here is my overall script
and here's how I set up the "walking" and "running" phase
So in a nutshell UE4 prints out those three print strings (in the first pic) during acceleration, but not on deceleration which is what I also want.
How can I fix that?

Hi! How do I set a custom AIController on runtime? When I try to Possess / Unpossess the pawn to set a new Controller, it gives me errors saying that my custom AIController returns NULL.
So the game starts and the pawn moves with its default AIController, but on an Event trigger I'd like to switch the AIController to a new one, let's say AIController_new . Any way to do this in game mode?

Anyone know how i can remove this gun mesh that is attached to this character

@fierce birch I suppose that exporting the mesh as FBX, importing it in a 3d app, removing the gun, reexporting the mesh in fbx, and reimport the base mesh will do the trick.
fierce birch
ok thanks, i thought there was a way in the editor

@fierce birch I may be possible. But i'm not aware about the way to do in the editor.
Maybe you can change the surface of the gun with an translucent material. It become unvisible 🙂

Any way to get random vectors on the "skin" of a mesh?

@late shuttle what does that even mean?
maiden wadi
@flat raft Your specific widget for the Trigger needs to handle the Drop if you want it to drop there. What'll happen is where ever you drop that payload, it'll more or less get any widget under the mouse, and drop it on the first one that is hitvisible. If it doesn't implement OnDrop, it'll just keep checking til it finds one that is or runs out of widgets.
flat raft
So my trigger slot, needs to be a separate widget.
maiden wadi
If you want it to work the default way, yep.
flat raft
So, if I wanted to avoid that.. and use my current setup
When I drop the green box over ammo slot, how do I go about ID ing that slot?

this video is esentailly free multiplayer with blueprints right?https://www.youtube.com/watch?v=u2Si2y2hviA

@sudden swan it's never free as you need to host all that stuff and the servers somewhere
sudden swan
can i locally host it on my pc during testing though
its hosted on a sql database so i can locally connect to it via an app during testing 🙂 but i will have to host it once i release
aws just gives a 24/7 vm for it to be hosted on right?
if so i already have a azure vm
can i use a azure vm to host the multiplayer since i have a free azure vm from their student plan
or does it have to be aws

So this for each loop is looping the same thing in the array infinitely. The do once node seems to work, well once, however if I add a reset to it from any point it loops infinetly again. How do I just say, do once for each item in the array each time this custom event is called?
earnest tangle
Based on what you've shown it doesn't look like that should loop infinitely
If you modify the array during looping or if you recursively call your event that could cause it, but not much else
severe iris
Is there any better documentation on the math node? I keep going to that article and being frustrated at how it doesn't give enough information https://docs.unrealengine.com/en-US/Engine/Blueprints/UserGuide/MathNode/index.html
A list of supported functions would be good for example 😕
tight schooner
@severe iris I've been frustrated about that too, but AFAIK no such documentation exists. You can always try stuff though; a surprising number of things work, e.g. Lerp() and RotateVectorAroundAxis() and etc.

VectorLength() works
I've noticed that functions that include parenthesis in the name such as "Lerp (Vector)" aren't available in math expressions

Hi hi. I was wondering print

So, I was wondering
this input action is consumed when I press a button
Is there anyway to not consume the input when pressing a button but still having the event On Hovered?
marble compass
how do you pass the reference of a variable to a function in blueprints? like i have float x, i wanna send the variable x into a function so the funciton can modify its value instead of just sending the value of x.
earnest tangle
in your function's properties, expand the parameter's options
there should be a checkbox for pass by reference
tbh it might be better to treat it as a value, and return the updated one... it's kind of unobvious in BP's what's gonna modify a ref so I feel like using them might lead to some confusing code
marble compass
thanks, found it
maiden wadi
@opaque warren Not exactly sure what you're asking for? If you don't want that LeftClick event to consume your input, just click on it and unselect the Consume input checkbox. But I don't know what that has to do with Hovered events?
marble compass
why does class == class not work properly in blueprint? i tested to see if it overlapped with the object of class that build area is set as default and it did, but the == returns false every time.
it works with cast to class node, but i want it to be done by comparing a variable since the blueprint will have children and i want them to be able to modify the build area variable to a different class.
spring hare
Does anyone know how or what this effect is?
https://www.youtube.com/watch?v=cWpFZbjtSQg&ab_channel=SebastianLague
opaque warren
@maiden wadi sorry for my description. I have a bp that has an event for the input action LeftClick. When I LeftClick I do a Trace line and I execute my logic. If I have a button in the middle of the screen and I click on it, this Event for the input action does not trigger. I guess that happens because the button consumes the input and then the event for the input action is not fired.
marble compass
update: solved my issue, just delete the variable and created it again and it works fine now, probably a bug with the engine
surreal peak
@spring hare Sebastian fully explains how it is done. You'd need to port that knowledge to UE4 though.

is having tick enabled for a BP a non-negligible performance hit even if nothing is done on event tick?
in other words, should i unbind event tick for every BP where event tick isn't used?
haughty ember
depends on how many actors of those classes you have, and before you ask I doubt anyone can give you a specific number
haughty ember
true, it's just about remembering
ripe rose
yeah
haughty ember
assuming you're derived class is actor, that is.
Some derived class might use it, so be aware of that
ripe rose
right
haughty ember
Personally btw, I wish the default was off
trim matrix
@ripe rose There is a project setting which disables tick by default. The Tick event wouldn't even fire if you had that enabled (in some cases).
The devs talked about how Tick is enabled there by default for easy and quick plug and play without hassle for the majority of developers.
It should be the other way around:
Enabling Tick for a class that needs it. Not disabling it as exception
That's what they recommend
ripe rose
ic
earnest tangle
If having it enabled has no performance repercussions then not sure why 🤔
it seems like there would be even if you did nothing
because the engine would have to call the function even if it's a noop

Anyone has ever tried to scale a spline mesh with an offset from the original spline ? In my case I have a spline (1) making a ladder. To the spline I add meshes to make rungs (2) and rails (3) but when I scale a spline point the tangents get all screwed up : /
haughty ember
If having it enabled has no performance repercussions then not sure why 🤔
@earnest tangle because new users would have to find that tick option just to use it
I'm assuming you mean by "it enabled" you mean the option where tick is unchecked by default

Hi! I'm making a custom text graffiti in blueprint by using text renderer and line tracing
but the problem is whenever I hit the key for the graffiti it sometimes prints half the text only
and how do I place it on surface normal
can someone help me with this
ripe relic
but then how do you make it custom text?
It uses materials
@trim matrix I have the text material but I don't have any idea how do I make it custom text
trim matrix
Good question, I am no material artist so I have no idea how to parametrize the text somehow inside a material
Might even just keep it as actor like above
What was your problem exactly?
maiden wadi
The only easy way to do text in a material that I know of is a mapping. And that's not necessarily easy.
ripe relic
What was your problem exactly?
@trim matrix So the problem currently is I don't know how do I use decal for the text material so I went with text renderer and when I hit the key for graffiti on a wall or a floor it prints it in half and I want it to face it on surface normal
is there any way to do this?
fallen glade
If anyone stumbles upon my ladder from the future, this is how I fixed my problem. Instead of relying on a singular spline, I recalculate a spline for each rail (just a point per point copy of the main one with correct offsets applied) and then use that one without any scaling
maiden wadi
@ripe relic Try this.
ripe relic
thank you will try it
trim matrix
@ripe relic I realized that the good thing about decals is that they behave exactly as real graffiti.
Widgets can easily have adjustable text.
What if widgets can be used as material, I thought. Then I stumbled across this:
https://forums.unrealengine.com/development-discussion/rendering/1603327-umg-widget-render-target-for-material
I looked at how TextRenderActor and TextRenderComponent pull it off. The way that works is totally different than anything else material-related
ripe relic
I looked at TextRenderActor and TextRenderComponent. The way that works is totally different then anything else
@trim matrix Ohh alright I will take a look at it and try it, thanks

I'm actually really curious how to pull this off. I'll do it too just for fun
Using the Render Target from a widget component as material parameter sounds like the solution (if you want to use decals)

In my Animation Blendspace the horizontal and vertical axis is -1 to 1.. In my character BP I set the walk / run speed to 270 & 600 depending if you're walking or running. How do I communicate this to my animation BP so the correct animations play depending on if I'm running or not? Right now the running animations are played even if the movement speed is set to 270...
My blendspace looks like this... 0.5 on both axis are walking animations... (This is from the RifleAnimsetPro btw, if that makes a difference?)
I guess I could do a check when pressing the movement keys and then clamp the axis value if I'm walking? Kind of feels hacky, so maybe there's a better way to do it?

I have a current setup running through pressed, released and held, and the only one that isn't triggering is released.

neon sorrel
Anyone know how I can detect which user interacted with a blueprint object easily?
I dont know if theres a way to detect the actor that activated it

Each object should be uniquely identified even if they're of the same class, as far as I'm aware, same for controllers. Beyond that it depends on exactly what you mean by "activated it".
neon sorrel
Well my door currently works with a E to open button, trying to figure out if theres a way I can get the user who just pressed E on that door
astral epoch
Could have the event on the door require an input variable that's a pass-by-ref of the character blueprint?
I'm assuming you are actually calling something in the door here.
neon sorrel
Currently I just have a interact event that checks the users inventory system and if they have that item then open the door
actually hmm
I could maybe just use that
Standby
astral epoch
If you're doing everything in the character blueprint then you already have your self node to use. Otherwise, passing said self in whatever event the player calls works too.
neon sorrel
Im using it all in the door blueprint, for the inventory I just called get player controller. But if I use that in a print string it will print out the same controller for both clients. Hard to tell if theyre different since its the same name
astral epoch
The key press is in the door too?
neon sorrel
Yep
astral epoch
You're testing this with multiple computers?
neon sorrel
Nope, just the one. When I print out the local player controllers player name it prints out my pc's name
Maybe I just have to test with another pc?
neon sorrel
It seems to work properly if it prints out my pc name when running a client
astral epoch
Print the player controller number?
neon sorrel
Hmm maybe yeah
astral epoch
Yeah I'd day that is a good sign
neon sorrel
Wouldnt that print a 0 or blank space then?
astral epoch
You said you have a ref to the inventory?
neon sorrel
Because using that same player controller works for my inventory system
astral epoch
Player 0 is first player.
neon sorrel
Yep I just use "Get player controller" as the target for my inventory check
Seems to work well
astral epoch
Ah.
If it's not hooked to a controller blueprint then it wont have a player ID assigned to it.
neon sorrel
Yeah, which is odd that it still works with a player index of 0
astral epoch
You're probably better off doing all inputs from the player character, especially if its multiplayer.
Rather than having press E et all in the door.
neon sorrel
Currently I contained most all of the code for the doors in the door blueprint itself, it worked well for checking the players inventory and all, but hmmm
If I use get player controller then get player name it prints out my pc's name
So I assume that would print 2 different names on two seperate pc's
astral epoch
You can test that.
neon sorrel
I just have to wait for some of my beta testers to come online and push out a build yeah :/
astral epoch
I'd suggest more but I cant check as I'm on my phone right now.
neon sorrel
Its all good, I appreciate the help
astral epoch
Theres probably a node that checks who fired an input but I'm unsure.
neon sorrel
Ill read up some documentation, that would be handy if there was
I think I found the issue
Seems since I run the door event in the blueprint for the door, it runs on the server, which opens it for all players which is good
But I just cant reference the user who interacted with it easily because of that

Why doesn't my character "Un-crouch"? 😦
rough wing
I'm not sure but Can Crouch might be false when already crouching?
Also there should be a "crouch speed" variable so you won't need to set max speed
white crypt
@daring vapor not that i know of, but its rather simple. You make a function in your bp and check the box "call in edtior", then when you click on the bp in your viewport you will see a button in the details tab. That button is your function, so you would have to get all actors of class (static meshes) and from a for loop you set new meshes
or always take a look at Mathews videos
ashen sparrow
I'm not sure but Can Crouch might be false when already crouching?
@rough wing It's not.. if I remove "Crouch" and "Un Crouch" from the end of the chain and do a Print there, it's all fine... :/

You've changed one of the two types.

Aaah.
You deleted a class.
That's what's happened.
Your 'bad cast node' there is what happens if you have a 'Cast to MyClass' node, and then you delete 'MyClass'.
My guess is, all those other missing pins are probably from trying to use something of that class after it's been deleted.

hey guys, having some trouble getting my character to rotate when entering a "Battle Arena" . I can get the character to move to the target location using target points but the rotation never works on the Z axis.
I've tried using local and world transforms and locations but I'm a bit stuck. Any help would be appreciated!

it doesn't update regardless of what Z value is enter, Ideal it should face the same direction each time, at present it keeps the character current rotation and moves them to the target point 😦

Ah - I have a feeling I know what it is.
I think this is a bug.
Recombine that Rotation struct.
And use a 'make struct' node for the rotation.
Try that, put the same values in.

I get initial worldspace position of cursor when I click in middle mouse button, verified working correctly
while input key is down, it will vinterp between (Current Position - Initial Pos) to AddWorldOffset
on event tick
To me, that seems sound, instead its literally just throwing the camera across the universe within a few ticks
woven wing
Hahah
bitter iron
and I think its got something to do with on play doing weird things to the position of some components, like -5432, -60102 XY???
white crypt
if you got two vector points and want to vinterp between them then use set world location
not add
bitter iron
am i stupid or should add work
woven wing
It won't work with v-interp.
bitter iron
oh
woven wing
What you could do, if you wanted to add it, would be to create a delta, and then multiply that by deltaseconds, and add that.
But setting the position using VInterp will do the same thing.
ashen sparrow
Is there a way I can put a Branch in here?
white crypt
blend by bool
ashen sparrow
Lovely.. Thank you!
white crypt
you will want to cache it
if thats what you are asking 😄
from default drag and type cache
then you will be able to use that cache more than one time
ashen sparrow
Hmm.. I don't think that is what I want.. After the Default I want to check if my CombatMode-variable is true or false.. If it is, go to the "StandAim", else to "ExplorationLookAround". Or should I place my AimOffsets elsewhere?
woven wing
That's why Tsauken is suggesting you cache it.
white crypt
still cache it
woven wing
Cache the outcoming pose of your Default state machine.
Name it like 'State Machine Pose'.
Then plug 'State Machine Pose' into both of your AimOffsets.
And have the bool blend after with outputs from both AimOffsets plugged into it.
white crypt
yup, duplicating state machine would be wasteful
woven wing
Your cursor is attached to your animated character?
bitter iron
myb if i seem stupid, this was easy in code but rn i have no idea why I can't get this to work how i want rofl
woven wing
Hah, I mixed you and Svedin up.
white crypt
you are deducting from impact point
woven wing
Also that 'Set' for initial mouse WS makes me anxious.
white crypt
it does
bitter iron
im new to blueprint
white crypt
the whole thing probably runs on tick
bitter iron
might have to elaborate
woven wing
You cannot guarantee that a return value will be valid except within the evaluation in which it was generated.
bitter iron
see that is one thing I'm confused about
timings in general are not explicit to me
does it re-evaluate what it needs once its called? even if its not needed?
i should do all this in c++ tbh
blueprint seems bad for this kind of thing
woven wing
I don't think it's that bad.
You're just unfamiliar with it.
And it does take some getting used too.
It's a different programming language.
bitter iron
yeah, its seems really good for behavioral stuff
just for this seems outside the intended use case
woven wing
Nope.
bitter iron
besides like third person shooters
bitter iron
ok, one thing im confused on then, why is it not moving the scene root by the same amount my mouse is moving in world space
ashen sparrow
I think I got it.. (?). One more thing; the Output Pose - I can't connect them both to the output.. So how would I go about solving this? Sorry if I'm a total noob - it's my first time working with Animation BPs 😄
woven wing
You want to connect StateMachinePose to your AimOffset, and then connect both AimOffsets to your Blend.
ashen sparrow
Please let it be beer?
charred berry
@woven wing if so, how do I fix a deleted class, can i reimport something ? Not a great programmer atm, a WIP
woven wing
Uhh... if you have perforce or git or some other kind of version control.
You can roll back whatever version you submitted the deletion.
If you don't - you're straight fucked.
bitter iron
so things shouldn't be on tick, what should be running camera functions
everything works
woven wing
OK so, some things should be on tick - things that happen over time.
Some things should not be on tick - things that respond to events.
Like a mouse click.
In Blueprint, all evaluation comes from an event node, whether that node is 'Event Tick' or otherwise. Functions called in a particular 'thread' of evaluation (the white lines emerging from one of the event nodes), the results of those functions are unreliable if used from another Event thread.
Unreal does not guarantee they will still have valid values.
So, in your 'Click' event, you should store all valid values as variables.
And then in your Tick event, you should use those values to do things over time.
In your case, I think you want to store 'Impact Point' as a variable.
Probably call it something like 'Clicked Location'.
And you probably want to use 'Set Actor Location', rather than move the Root component.

marble lantern
what node allows me to tell the get a ref to get all the actors in the level so i can run a custom event
woven wing
"Get All Actors Of Class", with the Actor class of "Actor" will get everything.
But you almost never need to do that.
The only time you'd need to do that would be something very odd and one-off.
marble lantern
i have some lights in a boss where it needs to change when the boss gets to a certain health @woven wing
woven wing
Ah, so if they're all the same class then you can put that class into the "Get All Actors Of Class" node, and then you won't get everything you'll just get lights.
And if it's only some of the lights, then you can add a tag to them, and use Get Actors By Tag and then you will only get those specific lights.
marble lantern
thing is i have a custom event in the light blueprint and i cant access it without a ref
woven wing
👍
That said, you can also have your lights find the boss.
And connect to his "I'm About To Die" event.
marble lantern
yea i was about to do that
woven wing
As it's a one-off, it's probably fine either way.
marble lantern
either way would be fine right? its not like one way is less cost effective
woven wing
If it were a standard mechanic - I'd say use the 'light subscribes to boss' method, but either way works fine.
bitter iron
I click, and it works
the problem is when I click, no matter where, it will move the camera so that my cursor is at world origin

Hey all its me again lol! I had another question, Im trying to create a simple fighter game respawn system similar to mortal kombat's. Basically the player fights the ai and if he wins 2/3 he goes to the menu level and is able to choose another fight. However, if he loses he has the option to try again or go back to the menu level and pick another fight. Any suggestions?
severe sparrow
hi.. i'm new here and also pretty new to unreal engine in general, maybe 20 hours in atm.
i have what is probably a very novice problem but i can't for the life of me find a solution on google, unreal forums or anywhere else.
I'm working with a shop inventory system using a data structure and data table, for some reason they will only work on the level that was on when i created them. I checked the level blueprint, I made sure all things are sharable to other blueprints, etc. The shop works 100% perfectly on one level, but when I switch to a new level it wont load anything from the data table. is anyone familiar with this?
shrewd mural
When you load a new level, those objects have to be re-created. So if you want to transfer data between levels, one of the ways to do it is through the use of the GameInstance.
Idk if this should be here or animation, but does someone know why this does not play the animation? It prints the string, so I know it's running through Play Animation. nvm I just forgot to call super in the base class.
For context, thats a user widget and Fade is an animation of text fading.

@barren relic two integer variables. One for player, another for ai. If anyone losses first 2 games then no need of third. I think about a macro which contains 3 output respective to player. Win, draw, lose. If win then playerWinCounter+1. If lose then aiWinCounter+1. If draw then go for tge third game.

@shrewd mural thank you! I had no idea it worked like that. I'll try to learn about game instance then
trim matrix
How do I reference a target point outside of the level blueprint?
I've set it location in the world and need to move the player to it, which I can do in the level blue print but not the first person character bp?
woven wing
@trim matrix - You can create an object reference variable on a blueprint in the level, and you can plug references into that.
If, however, it's like a spawn point, or a teleportation target - for the player, there are likely better methods to do.

simple berry
how would i go about hiding a skeletal mesh from everyone on a server?
woven wing
Like have an invisible mesh that's invisible to everyone?
Or one that's just invisible to some people?
simple berry
Invis to all
woven wing
Just set the either the 'visibility' property to false.
Or the 'hidden in game' property, if you still want to see it in the editor.
simple berry
Well I mean, it's supposed to be something that happens only when a certain variable is ticked, I have an event for it I just can't get it to work properly for some reason
woven wing
Can you show the bp?
woven wing
Ah, this is the same thing I was talking about earlier.
In "Server Hide" and "Server Death" you're using the values from another event.
Those values will not be valid.
So they won't be set.
Basically copy the 'Set Visibility' node down, plug it into the Server Hide node's 'New Param' parameter, and make it run off pin 1 of the sequence, and it should work.
simple berry
you see when i do this it dosent become invisible
simple berry
But when I do it the way you're saying it dosent work
woven wing
What does 'my way' look like?
simple berry
woven wing
Ah, you still need to call the event.
Use a sequence.
Call the event.
And then set the visibility.
simple lantern
How many texture samples is too many in a material?
woven wing
But do so from the ServerHide's NewParam value.

when connected it still dosent work

I followed crocopede's grab ledge tutorial (https://www.youtube.com/watch?v=4yjcwZLQqlE) and followed everything he did but I am facing a weird thing. As shown in the video, my character stops at the desired height and everything is fine but if I press any movement button in any direction for a single time, my character automatically starts moving in random direction. This is happening when I am setting my movement mode to ‘Flying’ when the character grabs the ledge as shown in the tutorial but if I keep it to default ‘Walking’, such random things don’t happen but my character doesn’t reach the desired height. Many people have faced the same problem and they have commented in the video but no one provided the solution. As this is a complex blueprint setup, I can’t provide the full code but I am posting as much as I can. Can anyone please help me?

Hey
I'm possessing pawns at the beginning of the game, but the aicontroller still executes
Or more importantly, IsPlayerControlled returns false
So even if I do this
This still returns false

I don't think events can be marked private
You could try using a function instead? Those can be marked both protected and private

Really? Wow... Im really falling in love with Unreal
earnest tangle
it says "tried to access index N from array of length 0"
so the length of the array is 0, and you're trying to read values from it

tall eagle
@tall eagle it simply takes the values from the editor right? i want to build a spline that shows the individual Points to teleport
@thorny cedar yes, it must be instance editable
thorny cedar
i set the value in my spline constructor for each teleporter element and it updates the position, but not at the exact location. I guess its not possible to add the element locatocation to my teleport to location before construct
thorny cedar
is there a way to lock a variable completely, that it cant be altered the editor?
earnest tangle
I think if it's declared in C++ you can just omit any Edit specifiers on it
then it won't be visible in any of the property panels to be edited
thorny cedar
@earnest tangle in c++ its obvious 😄 i want to have ana ctorr, that i can drop in my scene, but wont allow tto rotate it
dense mica
hardcode the actors rotation in construction script 😛
if you even try to rotate it, it should revert itself to hardcoded rotation i guess 😄
earnest tangle
that is a good idea lol
I don't know if you can prevent rotating an actor even from C++ unless you do something like that
thorny cedar
hm somehow i tried it and it didnt worked

use posses before maybe
anyone knows is sequence same thing as multi-threading? (in theory ofc)
signal palm
It just executes them in order
earnest tangle
It's just a way to organize your nodes differently if needed
dense mica
understood. i was saw some multihreading things while researching my queue system, then wondered whats the difference
i guess multi-threading is about memory
im pretty sure im overlapping the object lol, why its not triggering overlap event?
breakpoint doesnt trigger too
signal palm
You don't have to check if it implements the interface btw, you can just fire it anyways
dense mica
doesnt work either
weary jackal
Rather than checking actor being overlap. Try overlapping sphere collision. And check with casting to your player
dense mica
tried it too... not worked, event hit works but overlap doesnt work
whats the difference anyway?
weary jackal
In actor overlap it checks fpr whole actor. And sometimes the actor held out of bounds. So it's good to work with colliders
dense mica
i created a sphere collision to check if it will work
the problem is not the collision channels or actors, its block my pawn on level but not triggering the events 🤔 thats weird
severe sparrow
does anyone know how one could share a data table through multiple levels using a gameinstance? i'm not having any luck. my goal is to share the same NPC with the same inventory widget that utilizes a data table and data structure, but they only work on the original level.
dense mica
maybe use savegame?
as far as i remember beginplay should trigger every new level loaded, right? on beginplay get savegame data (your data table)
save when needed so data wont lost (eg. save when inventory changed, new item added, removed an item etc.)

is this a good way to check gamemode?
i want to add different logics between different gamemodes
but i am handling the logic on pawn, thats why i need to do this
surreal peak
no
You are comparing a BP Asset with a Class Instance. That's the most wrong you can go.
If you want to know which specific GameMode that is, you can use a Cast
Also keep in mind that you always only can have one GameMode at a time. So theoretically you should be aware of what Class you are using.
You can of course change the GameMode per Level and when switching Levels, but during a Level the GameMode stays the same.
dense mica
okay eXi, thanks 🙂

hi ! i think this is pretty simple but im lost.
im trying to call an event from another actor blueprint but cant get the correct object input when casting to it
if anyone has any pointers would be appreciated , been on this for hours
dense mica
is portal_bp a custom actor?
civic sand
its from when you add a bp and chose actor , is that a custom actor ?
dense mica
yes
dense mica
so you cant access a custom actor with only casting
you somehow need to get info about that actor
civic sand
yes , thats where im falling over
civic sand
its in every level
dense mica
but only one for each level, right?
civic sand
yes
dense mica
ok then you're lucky
normally you should learn about blueprint-communications and containers etc. but i can give you an easy solution for now (i mean "for now" because its not recommended for every logic-setup please dont get me wrong)
use "getallactorsofclass"
civic sand
ive been doing lots of examples but cant get anything ive learnt to work
dense mica
if im not wrong, there must be something called "polymorphism" in c++
so you create an actor, define some values, logics, codes to that actor
then create another actor derived from that actor
what you see on the actor creation window is actors derived from engine classes
"Get Player Character" gets the players Character actor
Derives an actor from that
You actually use that
With casting to original Character actor you can access to your own Character
But in custom actors thats not that easy
There are ways to access custom actors, like spawning them on gamemode then promoting the return value to variable, get all actors in class node, or using event hit
civic sand
ok
dense mica
but you dont need a specific actor to access, there is only one actor in your level
so get all actors of class returns as how many actors you have in level
you can just use it
civic sand
i tried binding but the problem was there are multiple coins
dense mica
i would create the portal_bp (spawn) on gamemode* then reference it by promoting variable, then cast to game mode and use it there
civic sand
thats great thanks , ill try that
marsh forge
what is the standard way to apply a force over time to an actor/component? I would imagine it is addforce but I keep running into bugs with that
basically if I wanted to apply a force while a button was held down, would I want to use impulse, addforce, or something else?
dense mica
im really not into phsyics but i guess impulse
im just saying that because i saw impulse too much in tutorials 😄
add force is kinda for movement maybe(?)
signal palm
Impulse is usually an instant push and force is usually a constant force that's being applied for multiple frames
marsh forge
ah, so then I guess I have to figure out why it's acting so wack
earnest tangle
AddForce should be the way to go if you want to apply it over several frames
You need to multiply your force by deltatime though
iirc
marsh forge
for some reason addforce is requiring really high values and it kind of breaks depending on the event
I didn't multiply it by deltatime
so that might fix it
lemme give that a shot in a sec

What would be an optimal way to load character models in blueprints without overwhelming the system memory?
In my game i have a character select where if players click on a character, their model will switch to that new character model and it will be saved to their id card when transitioning to a gameplay map
Right now i have the skeletal meshes in an array and when a player selects a character it uses an integer to find that model in the array and set it as the preview mesh
bitter iron
what would be the most foolproof way to enforce a level bounds? My first thought is to use collision channels
winged badge
On average each character takes up around 30mb and i intend for this game to run on systems with 4-8gb ram
trim matrix
is this a good way to crouch?
trim matrix
what should I use then?
trim matrix
Thanks
winged badge
If something such as a skeletal mesh is an object array as a default variable, will that mesh be loaded in even if i dont use the array?
marsh forge
so if I wanted to use addforce on a player, would I set the target to character movement?
just want to make sure I'm not setting this up wrong
dense mica
no set the pawn itself
what i meant movement before was moving the actors with phsyics, it wasnt related to cmc and i dont even know what i said is true 😛
marsh forge
oh I could have sworn it gave a compile error when it was set to self
lol
I am incredibly smart
dense mica
lmao
signal palm
You should actually use the character movement I'm pretty sure
marsh forge
it looks like it targets character movement component when you leave it as self anyway
which is why I was confused
well that's good
guess I have to give it a test and see if it decides it wants to act buggy
signal palm
It needs high values because the delta time is like less than 0.01
marsh forge
Noted
The main issue I was having with it earlier was it not working with one controller, but then having it add a crazy force when I had the input set to 0
signal palm
Hmm I just did a quick google search and found this: "Add Force and Add Force At Location automatically account for the delta time."
signal palm
But then some people say that their force is much stronger if their fps was low
marsh forge
Ue4 go home, you’re drunk
signal palm
Maybe just use impulses 🤷♂️
marsh forge
Impulses do work fine but I’m not sure how performance friendly that will be if I want to set up a drag force
Only one way to find out lol
signal palm
Found this on an old forum post
"AddForce accounts for delta time and should be used for applying force over more than one frame, AddImpulse does not account for delta time and should be used for single 'pushes', like from an explosion or being thrown by a player. The reason is that if you use AddForce for throwing or an explosion, how far the object moves depends on the framerate at the exact frame the force was applied, rather than being independent of framerate like AddImpulse is."
Do whatever you want with that information lol

Question: In a widget anim, if it get's called to play only once, do I have to tell it to stop once it's done? It's like a one-shot anim
As in, does it "garbage collect" it after it's done?
That question is weird but I just want to know if after it's playing if it's lingering
dense mica
on the last frame animation stops by default?
if you dont loop it
no idea about gc part
gusty shuttle
Aye, same. Thanks for Rubber ducking though
bitter iron
4 days into blueprint, seems to be especially vulnerable to my everlasting stupidity, feels so much harder to look at then code but so weirdly useful at the same time
So far, I feel that epic could use maybe a better way to show EXACTLY what something is doing, which I feel is the big strongpoint with c/cpp
signal palm
What do you exactly mean?
bitter iron
let me find an example
signal palm
I never used cpp in ue4, only for non ue4 projects just because blueprints are quicker to prototype with so I get lazy and don't wanna switch to cpp later in the project
bitter iron
ConvertMouseLocationToWorldSpace for instance
my initial assumption was that it literally did just that, but it doesn't, it allows you to do that with a tiny bit of work
signal palm
I mean it does that? It returns the location in the world and the forward direction from your camera IIRC
bitter iron
I suppose it does still yea
gusty shuttle
@bitter iron I've used that node before, it always gave me wacky results somehow. Probably was using it wrong on my end
bitter iron
or even just documentation, because a lot of blueprints are just magic
@gusty shuttle I also had to look up how to actually use it
since It didn't click for me
signal palm
Hmm maybe I'm too used to blueprints but it clicked for me instantly when I saw which outputs it gave me
bitter iron
it just takes essentially where your screen is, and then figures out a direction based on where your cursor is on the screen
yea the outputs let you see what it does
but if you are tired, or new to blueprint, a lot of nodes have extraneous outputs
that you don't really need to use it, they are just there for any use case
so the direction is like "ok idk why I'd need that" and you ignore it
and nothing is working, then if you are smart (I was not) you look at other nodes before you examine what that one is doing
signal palm
Yeah I guess that makes sense
bitter iron
but in code, it seems slightly easier to understand functionality, and especially trying to build something with math I can basically drop in formulas from PDF's if I want to
gusty shuttle
Maybe GetMousePositionOnViewport?
bitter iron
transforms are how UE4 refer to vectors in math sense right?
bitter iron
GetMouseVectorsOnViewport seems fine
but its nitpicky
its more of a flaw with the medium than the node itself
or english tbh
signal palm
GetMouseVectorsOnViewport seems fine
@bitter iron You mean for the ConvertMouseLocationToWorldSpace noed?
bitter iron
ye
signal palm
Honestly GetMouseVectorsOnViewport would probably confuse me
bitter iron
yea thats what i mean
you can't make it better, its just the medium
im sure they have a ton of people having meetings on the names of nodes and shit, like every other company
just this week I had to participate in a meeting where my icons were deliberated about for 4 hours because one person thought they weren't good enough, and at the end he changed his mind and says he likes them, so same thing
signal palm
Idk honestly I find the node names pretty good usually, also they are usually just cpp functions exposed to blueprints, and their names are pretty much the same as I would name my cpp functions
bitter iron
usually pretty good yea, like I said I had no experience with this kind of thing at all, and in like 10-12 hours of learning it I've got a decent little camera system
and thats with like 9 hours of figuring out why my math didn't work
and its because I didn't have a addition node in the right place
9 hours.
signal palm
Oh well
bitter iron
ye
signal palm
I've done singleplayer bp only for like 3 years though I had some long breaks
Even though I've started learning cpp like 6-7 years ago, still haven't tried it in ue4
bitter iron
it look pretty dont it?
bitter iron
do you hate the curvy lines as much as I do?
bitter iron
god if epic gave me a editor preference thing for circuit board style interface my nips would explode
OH GOD
signal palm
Lmao
bitter iron
what the fuck
signal palm
bitter iron
no seriously
signal palm
I actually knew where everything was idk how lol
bitter iron
and they are so far apart you can only see one node at a time when you zoom in
bitter iron
your blueprint is a fire hazard
signal palm
I had a skin system
Where it had a switch
For every skin you can buy
And I manually hard coded every 3d asset for that skin
So when I wanted to add a new skin I had to change the code in like 5 blueprints
bitter iron
LOL "yea this is how fortnite does it"
signal palm
So I fixed that now and made a datatable and now you add a skin with a click lol
And I wanted to continue to work on it but it's just bad
So I started doing my first real multiplayer project a few days ago
bitter iron
yea, like I want to add velocity to camera rotation, so it feels nice, make everything feel better, zoom to cursor, gamepad controls, wasd etc
better to just remake it from scratch
bitter iron
is there a way to hide comments
signal palm
I haven't made it a habit to use reroute nodes
bitter iron
like folders in photoshop
signal palm
Hmm not sure
bitter iron
it would also be nice if they had a portion of the screen where It lists all my comment blocks
so i can double click there and zoom to it
bitter iron
LOL
signal palm
Or the whole block
signal palm
Yeah xD
bitter iron
i mean the block
signal palm
Not sure then
signal palm
There is also a plugin that makes your lines straight automatically
bitter iron
i wonder if it would be possible to have a cpp node where you can write cpp code as a node itself inside blueprint editor
signal palm
I remember wanting that before too haha
bitter iron
for my econ sim I am probably going to have to write cpp classes for the math and use them as blueprint
you can just use vs but it takes so long to load
and i don't feel like having a visual assist subscription right now
signal palm
Idk if I should try cpp for this game I started working on
bitter iron
i think cpp + blueprint is way better than either individually
signal palm
Well yeah
bitter iron
some things are cleaner in code, some things are way cleaner in blueprint and more modular
so you'd write functions in data oriented way in code, then use it modularly with blueprint to implement it
signal palm
I always say I'll try cpp in this project and I never do lol
Yeah I could just write functions and expose them to blueprints right?
bitter iron
yea
one problem is if features need to change, but with blueprint structure as long as you have the same in/outputs nothing should completely break

Heyo! Hopefully a simple one for someone... I have My item classes as a string... 'item_C' .... and i was hoping for a node that removes the '_C' leaving just the items name. So from string element to string element removing '_C-
any takers? >_<
bitter iron
sure ill try
is there a reason to use strings though?
you can build custom variable types iirc?
unique holly
I'm trying to use the class of the items to pull defaults from a data table. Converting the class to row name seemed a simple route... i might be too noob
signal palm
Sooo that doesn't look like very good code but sure that should be easy
bitter iron
strings are best for literally just text
if its something the player needs to read, string is nice
unique holly
yeah, its just to get it to work on the data table row get node.
needs a name input >_<
signal palm
unique holly
You're a genius, i'll let ya know if it plugs my gap >_<
bitter iron
oh you are getting the row named Item_C
not items being named Item_C
misunderstood
unique holly
Exactly, And i can hopefully just set the class for any item in game... then adjust all the details for any item on one data table...
in theory...
signal palm
Hmm not sure, there are a lot of different ways to manage data in bps, and my old projects were terrible at it
bitter iron
i think its more difficult is what i mean
unique holly
This trick makes me very happy!! >_< Thankyou! I believe it lets me connect excel into my stuff... via csv files and data tables...
bitter iron
one line can be 1 node, or 15 lines can be like 100 nodes if its data management of something really complex

Hey guys, do you know if there is a way to make multiple highResShots in a row ? I put this in a loop but only the last screenshot is taken
signal palm
I think that's because it saves it into the same file so it overwrites the old screenshots
I haven't used that before but I think you can define the file path
So you can maybe take the index of the loop and append that to a path so it saves the images to file1 file2 etc
rose flint
Interesting Idea, I don't think it's that because it uses next available name by default but I will try thanks

Is there really no way to fix a missing class born out of error inBP compile ? I can yes easily make a new project and migrate my terrains and avoid all of it and delete old project, but I like fixing things, so there really is no way ?
It would take forever on my i5-3570 no doubt, would a engine recompile do anything for THAT ?:

I have a map with multiple "DeathTraps" scattered:
Those DeathTraps have a NavModifier to not be included in the NavMesh:
Which works fine in 4.18 as you can see above
However, when I use the same thing on 4.25, it does not work
The NavModifier does not change anything in 4.25
Anyone knows if that's a bug?

I have a second camera in the scene but I don't know where it comes from
Is there anyway to find out?
It only spawns when i start the game it's not in the level while in editor
It's spawned at 0-0-0 with 90 degree perspective

I have a text widget as pop up I wanted it so that it always faces actor but having problems that while it faces facto its also rotating the entire actor to face my camera and not just the text widget above it. any idea how to fix this?

hi guys, when I change camrea rotation, my character walking slow
what could be the problem?
signal palm

@onyx pawn You are setting the actor rotation
You need to set the widget component's rotation
onyx pawn
how would I do that?
onyx pawn
got it thanks

hey guys,
which one of these functions would be more expensive? its a general example, but a programmer told me that 2. would eat up cache memory because its a recursive function. im no programmer so i dont know, but im curious.
open linden
@flat raft so 1 would be more expensive.
its calling "delay" all the time but delay is only allowing 1 exec to go thru it?
because its basically ticking all the time, even if nothing happens, right? but is a tick without connections at all expensive?
i totally get that "tick=evil", i'm trying to understand the input a programmer gave me.
open linden
😄
thank you for your input.
the original example was this:
https://cdn.discordapp.com/attachments/760995491190013953/763861700440752178/unknown.png
im using that to play sounds from time to time
flat raft
so, the tick is checking your bool every frame
in #2 your bool is being checked every 2 sec

Hey all, i'm trying to find the math to get a float, pref normalized, that tells me how much i am moving forward
open linden
Hey all, i'm trying to find the math to get a float, pref normalized, that tells me how much i am moving forward
@snow halo velocity? or distance traveled?
snow halo
forward at all even even if it's somewhat to the left or the right
so far i think i'm failing
woven wing
That would do it.
snow halo
i need the float to be 0 when moving backwards, fully left or fully right, backwards right and backwards left
does my math look correct?
waxen mulch
Hey any clue why this dosent update when a new player joins?
this is on my gamemode BP sorry im kinda new and just learning so
woven wing
@snow halo - I think you'd get the same effect with just the clamp.
open linden
@waxen mulch i think gameMode lives on the server, so if you call getPlayerController ID 0, its always gonna be player 0
woven wing
That just cuts off the negative values for moving backwards.
So you'd have zero for moving backwards, and you'd already have zero for moving at right angles.
waxen mulch
Wait so what would i call?
open linden
no idea.
maybe on playerController - cast to gameMode - call some "new player joined" function and give him a new, unique ID, maybe increment an int or something. dont know mate, never worked with BP
because playerController is always bound to the client thats playing
snow halo
@woven wing i think moving purely right is returning a value other than zero though
and i need left or right to be zero
woven wing
That doesn't make sense.
snow halo
testing rn
woven wing
A vector dot a vector at right angles should be zero.
snow halo
1 forward, -1 back, -0.5 left, 0.5 right
woven wing
No.
Dot doesn't care about left or right.
It's basically measuring how much the angles 'project onto' each other.
So left or right project the same.
snow halo
then i have no idea why left and right return values if i print the dot return
i can see i'm just strafing my character
woven wing
So this always prints zero.
I don't know how your character works, but my guess would be that your pawn is rotating somehow.

Hello guys, just found https://www.udemy.com/course/unrealblueprint/ this course, is it good entry? I, myself consider more like 3D artist, that would use unreal for those things but being able to do something in blueprints would be very handy, but not quite sure, if this is good course for 13 euros 
open linden
@unique zealot mate, if i can recommend you a course on BPs,its this one:
https://www.udemy.com/course/unreal-engine-4-blueprints/learn/lecture/8556554#overview
amazing teacher, superb examples and explanations.
this was my first BP course on udemy and i basically got high on it, bought a bunch of other ones, just to find that none of them were even close to the one i posted. hes an excellent teacher and you feel it.
stiff hatch
is there any good plugins for database work for BP?
open linden
i dont know about the other course, i can only highly reccomend the one i posted.
in the end, buy both, give back the one you like less.
unique zealot
Whoah, 31 hours, thats something.. thanks for recommend
wait, you can give them back? Thats weird, somebody can abuse that :/
lunar coyote
well, while I don't condone that, Udemy themselves are playing dirty with their perpetual 90% off deals
open linden
wait, you can give them back? Thats weird, somebody can abuse that :/
@unique zealot yes ofc. i gave back 4 courses because they were not on par with the one i posted. jesus, watching someone make mistakes and fix them - IN A COURSE, without intent, jus "oh well we just gonna fix that lol"
well, while I don't condone that, Udemy themselves are playing dirty with their perpetual 90% off deals
@lunar coyote yeah wtf i also thought "im a lucky guy" with the sale but nop... they do it all the time. 😄 typical salesmanship.
wait, you can give them back? Thats weird, somebody can abuse that :/
@unique zealot i would never in my life give back that course. enjoy. 🙂
i just was able to finish a game jam project as a sound designer that also helped progrmmers a shit ton and polished the game in the end, only because of that guy teaching me, its intense. 🙂
unique zealot
Yeah, thats very awkward to make mistakes in course, haha. I will buy both, start with that shorter and then switch to that with portuguese voice 😄 thanks! 🙂

Wait so what would i call?
@waxen mulch If you want to do something when a new player joins, you can use the OnPostLogin event in the gamemode bp
crimson charm
how do you change the speed of a particle effect or at least change the speed it plays when called from a "Spawn emitter" node?
tight schooner
As far as the blueprint end is concerned, you set a float parameter on the effect
crimson charm
tight schooner
On the effect end, the workflow differs between Niagara and Cascade, but the gist is you want to make a float parameter drive the spawn rate or w/e
@crimson charm There's probably a node you can use on the output of Spawn Emitter Attached called Set Float Parameter

@robust cliff Usually you have a bool so you play the death animation. Then you simply don't have any arrows leading out from the "death" animation node
