I come from a long background in C++. I liked the BP system, though. I wanted to familiarize myself with it so I could ease my nephew into programming via BP, but I am starting to run into too many issues, not being able to do certain things that are easily done in code.
trim matrix
@tight venture i fully agree with you and i come from c# and unity so i'm at the disadvantage of not knowing C++ but i'm really hoping to release the game i'm working on now to help with me only earning ~$200 a month (before COVID-19, it's now $0p/m) and once i've released this game i'll drive head first into learning C++
tight venture
C++ is a beast of a language. It's huge. Helps to start with C, IMO, but I know that opinion is... debateable, to say the least.

How big of an enum is too big, typically?
tight venture
um... that's a weird question. There is no such thing as "too big of an enum", but it might be a code smell if you use them a lot and they're all really big. Most the time, when I used enums (pretty rarely) in my code, they never exceeded about 4-5 items. But that doesn't mean that using an enum of say, 128 things, is necessarily bad. Just unusual.
a lot of really long enums is something you'd see more in C code, not so much in C++
true marsh
I see I see thanks
trim matrix
@tight venture i do agree it is a beast, i see C++ and C# as the best languages ever (for what i'll probably ever program) but like you said it's huge and so is unreal engine 4 and i dont even know the latter very well IMO
tight venture
I know a lot about C++. Very little about UE
trim matrix
wanna trade? i'd prefer knowing C++ over UE
tight venture
@true marsh Describe what you're trying to do or give some code snippets and I may be able to help you out further
Haha. I learned C++ in college, and then over the next 5 years or so, building and maintaining a networked rendering program for an IoT business
C++11 was a huge milestone. Don't write pre-C++11 code IMO
true marsh
If was setting up a enum for all stats in the game, all resists, attributes, crit/dodge/block, regen values if it would be better to have them categorized or if its fine to have them lumped in to one big one
tight venture
That doesn't sound like what you want an enum for
tight venture
you want an enum for cases where there are a finite number of variations of something. Like COLOR {red=0, blue=1, etc...}
tight venture

tight venture
@ripe turtle What type is that "In Animation" input? Can you include in the picture the stuff to the lower left?
ripe turtle
its a get animation
its a 1 second animation to make a progress bar go from 0% to 100%
@tight venture
tight venture
well, it looks like your animation stops down in the lower right there. Why not print the string right before you return from the function?
ripe turtle
i want to do it right after the animation is done. im not going to have it as a pring string forever i want to do other stuff i just want to know how to tell when the animation is over
so everytime it is done it loops and repeats as long as im holding e. everytime it loops i want print string to be triggered
tight venture
does it have to print the string at a certain time of the animation loop? what about printing it before the animation instead then
when you get the 'E' input
ripe turtle
everytime the animation is done and then the animation restarts
as long as im holding e the animation will loop forever
tight venture
and you want it to print every time E is pressed? How about making a new event when E is released? and then print it then
ripe turtle
no i want it to print everytime the animation is looped
ripe turtle
i was thinking maybe have a 1 second timer start everytime i press e and then have it loop until i release e but i dont think you can cancel a timer once you start it.
ripe turtle
it prints repeatedly as long as im holding e
all i need to know is how to figure out when an animation is done and is now looping
tight venture
I am sorry, I don't really know much about using animations in UE. I am an experienced programmer, though. It looks like that "Stop Animation" execution path would be taken when the animation is finished, but you're saying that that is only reached after you stop holding E, and multiple animations may have been executed during that time?
Sorry, I can't help 😦 I don't know. Anybody else?
ripe turtle
ok thanks
tight schooner
How would i make it so print string is triggered immediately after the animation finishes?
@ripe turtle
I don't have animation experience but I have heard of an "anim notify" function. Maybe you're looking for that. https://youtu.be/vY8ENkjBY2I

ok thanks
ive been trying to work around it for 2 hours but i cant. ill look into that now
vocal urchin
Am I going crazy? Why does this not print??
I can grab the length and print that. Why does it not work if I do simple division? 😄
ripe turtle
dont know what im talking about at all but maybe try to convert to a float first?
vocal urchin
Actually, it looks like it is printing, but it's not doing the division
So...I revise my question - why won't it divide?? lol
ripe turtle
what does your length equal
vocal urchin
It varies, it's just capturing actors within a bounding sphere
Could be zero, could be 50
But this is running on event tick
ripe turtle
not sure
static charm
well 1 divided by 50 is 0.02
which an integer in ue4 would probably just go to zero
so jack was right
use float
vocal urchin
ah...I see now
Haven't had to divide something like this before until now.
Yeah, it's just dropping it as an int.
Thanks guys

I'm trying to move a series of vector points in and out based on a parameter I'm calculating (the float coming in). I've actually got it working how I want, but the resulting array of vectors is suuuuper tiny instead of the size I'm expecting. I'm pretty sure I'm not doing this in the most optimal way, so how do I adjust them in relation to the original scale?
As you might imagine, the unit formation shouldn't be that tiny.
I thought I could just divide the vector, but that causes some infinite values

@old prism Are you using the "pressed" and "released" input pins on the input event node?
Try using a "flipflop" node.
Easy way to toggle events without using a boolean variable.
maiden wadi
@vocal urchin What are you trying to do with your vectors?
old prism
Massive thanks renzu
maiden wadi
Cause you're only setting the location of one actor? That or you're setting the location of all of them to the last index in that vector array. Can't tell from where the actor reference is coming from. Most likely the second though given the self reference right there.
tawny tinsel
so how do i fix this?
the refrence is the capsiume component
how do i set it for each actor in level?
well that was easy :3
thank you for the help with your vague instructions i was able to figure it out
it seems to all work now
tight schooner
looks like you still got another thing plugged into Target, FYI
maiden wadi
Typically you would set the locations right after spawning them, all on the same loop from the savegame information. But that's using standard savegame practices.
Cause then you'd have the class type that they were, spawn them in, set their locations and variables back up with the spawned actor reference, and loop all of that for the number of them you saved.
maiden wadi
Right now, you're telling each of those actors after they're spawned to get all of them and set the locations of all of them. If you have ten AI, you're setting each of their location ten times which is a hundred set location calls when you only need ten. If you're going to run a GetAllActors, do it from somewhere that only runs once.
tawny tinsel
it only runs once here at event begin play so the fps is alrit
maiden wadi
Is that in the AI blueprint?
tawny tinsel
yes
maiden wadi
Then it's being called on begin play for every instance of that AI. If you have ten AI, that will run ten times. Ten loops calling set location ten times for a total of a hundred setlocations.
tawny tinsel
yes but thats only once

here's a weird one, not sure how this works but
I gave the game a VR mode, based off the FPS template
and apparently when they load in it's like 2 FPS
but when you play normally it's 80 on mid end and 144 on high end+
I know that VR is high spec but the very small map I have shouldnt take so much to make it 2 FPS
I don't see a reason why VR would lag so badly

weird one, but GPU profiling will be useful
unique hollow
aight lemme get RenderDoc out

how would I use the GPU profiler?

although I do not have a VR headset myself, my friends do, I just wanted to add the functionality so I'll probably need to get them to do the thingie
lemme GPU profile in normal mode first
covert stirrup
yea doing a project for VR right now, even having one is a pain in the ass
unique hollow
maybe that can leave a clue
yea
Especially since I'm very concerned on how it will turn out for grabbing objects
cause rn all of my physics objects are just StaticMeshActors that get pulled to a GrabLocation in the FPS character's view range and apparently you need a BP script on stuff to make it work in VR
maiden wadi
In general, VR shouldn't be any different than normal. What are you doing on your VR controls? Maybe it's something there that's being called too often or something.
unique hollow
lemme show you
the basic stuff
and that's it
also this
but these are gonna be my collision boxes
and controllers to serve as hands
the particles will be lasers so you can see where you're pointing at since no hands
maiden wadi
I mean sure VR practices are a little different. But that's for stuff like not shaking the camera too much or that the pawn is set up slightly different. Nothing that should cause an 80 to 2 fps difference. Not unless they're playing on a literal potato.
Nothing there would cause that. Not even close.

What engine version are you running? I'll see if there's anything general going on.

So I'm testing input on this ATM model to toggle a light when I press F and it works fine. However, when I run the same code on a different character model, nothing happens. Any ideas? Maybe it is because the character model is using a Character Blueprint instead of an Actor blueprint like the ATM mesh? Even then I feel like this simple code should still run, but it's all I can think of.
maiden wadi
@supple rivet Sorry, your explanation is a little confusing. You have one ATM machine and two characters? Or what is the third actor besides the atm and character?

@maiden wadi I have two blueprints, an ATM mesh and an NPC character

Is that screenshot in the character or the atm?

What are you trying to toggle visibility of in the character?
supple rivet

vocal urchin
@maiden wadi I'd gone to bed when you @'ed me earlier, but basically the problem is this - I have a group of vector positions that are stored in an array. For various gameplay reasons, I want to tighten their arrangement (move closer to 0,0,0) based on the number of actors in a bounding sphere. I have to do this on event tick, because it's based on a movement the player is making. So, I got the length of the array storing the number of actors overlapped within the sphere and calculated a decimal value I could multiply times the vectors in the position array, thinking this would then shrink them dynamically. But, it only kind of works and creates a super tiny version of what I'm trying to accomplish. So, I figured I was probably not handling the vectors properly.
In theory, this is the unit positions for a formation. But, the "formation" is the size of one unit's foot. So..not going to work 😄

What's the recommended way for setting up collision sounds? Like a wood crate bumping into a plastic barrel should play the Wood Collision Cue and Plastic Collision Cue
I'd prefer not doing it per actor (would require creating a blueprint for the Static Mesh just for this). A global event would be nice where I could just handle it for any component hits

I am struggling to reference objects in this BP, anyone know whay ?
even if is is selected, nothing related to it comes up when I search in the bp
covert stirrup
what vector are you looking for?
BP's read left to right, generally speaking anything from the left doesn't give anything, it only looks for something
so if you want a "Get world Location" to input into the location vector, you'd need to get a reference, from a Static mesh for example

Hey doing University work need some help using a VR template and i believe that the widget interaction component is stopping the teleporting any ideas on how to fix this ?
covert stirrup
have you changed it from the default settings how it would be when you first load up the project?
dapper cradle
@covert stirrup so it needs to be a static mesh that I have highlighted in order to reference its location ?
I have seen a spawn target used to spawn things in a tutorial so I was hoping to do the same (the tutorial referenced the spawn target the same way I wanted to)
I just need the location and possibly the rotation for spawning my actors in at the right spot.
tight schooner
@idle horizon maybe ask #virtual-reality
idle horizon
ok
tight schooner
@vocal urchin maybe I'm just speaking for myself here but there's a lot going on in that graph that I don't understand. If you just want an array of vectors to be closer to the origin, then multiply them by some float between 0 & 1, of course. I don't get why it's adding a normalized version of itself to itself; wouldn't that ruin the formation? I sort of get the array length scaling factor — more actors shrinks the vectors somewhat. I suppose I fundamentally don't understand where the problem lies. What happens if the vectors aren't modified at all?
covert stirrup
@dapper cradle yes you need a reference of something
if you have no reference, it will just be 0,0,0 and spawn in that point of your level
(well technically either level or reference frame, if it's a relative transform)
idle horizon
Also for mine above
dapper cradle
Thank you @covert stirrup !
vocal urchin
@tight schooner If I don't normalize it, for some reason I get infinite values because this is running on event tick
tight schooner
It's rescaling itself on every frame? It might be better to make the scaling factor separate from the vector array. Like the array just stays the way it is, but on tick the scaling factor is altered. And whatever retrieves and uses the vectors does the scaling on demand (vector * float) without altering the original vector array.
The problem with stuff applying to itself every frame is yeah, you get situations where it's compounding toward zero or infinity very quickly.
I have a vague recollection you wanted mousewheel to determine the scaling factor...?
vocal urchin
No, that might have been someone else.
I was hoping to have this be dynamically achieved, and then optionally controlled manually.

Is there a way to set the refresh rate in ue4?

There is a frame rate setting in Project Settings

there's also a way to change the viewport framerate but don't recall how to do it offhand...
@trim matrix You'll have to ask #graphics ... The material graph isn't Blueprint. Blueprint is game logic script.
tight schooner
@vocal urchin my suggestion wouldn't change the rescaling-itself-by-itself-on-tick problem where it compounds toward zero or infinity, but abstracting the scaling factor to a single float would make it easier to manage at least. For example you can clamp a float.
vocal urchin

@supple root I have no animation knowledge, but I'll say generically that, in plain English, the blueprint is...
- Getting pawn owner.
- Checking to see if the pawn owner is of an "IKPawn" class (this is fundamentally what a "cast" does).
- Getting a reference to the camera component of the IKPawn class
- Getting the world transform of the component.
- Saving the transform to a variable.
supple root
but how does it get that camera reference?
like every other UE4 tutorial, it just says 'do this' but doesn't explain how or why, and if I drag off that and type 'target' or 'camera' or 'get' there are no results in the blueprint system
so as far as I can tell he has a different version, or is using some innate knowledge that people who use the engine have but beginners dont have
there is no such thing as GetWorldTransform in my blueprint editor, for example
tight schooner
By casting, it's able to make assumptions about what that target object has. It knows that an "IKPawn" has a camera, so you can get a reference to the camera if casting succeeds (it passes the check).
You can get world transform for any component; it's a generic node
vital pike
The PlayerController is described in the docs as ' implements functionality for taking the input data from the player and translating that into actions, such as movement, etc'
..but most examples I see putting the 'Add Controller' inputs onto the character BP. I'm confused
tight schooner
Drag out the "As BP VRPawn..." pin and you'll have access to all the components, functions and variables that the class has
(Again, I can only speak generically cuz I don't know about animation systems in particular.)
supple root
right, and that's the issue, I don't have the things he does in the tutorial
I know how to do this in c++ as a programmer, but I don't know how to do it in ue4 c++ because there is no tutorial or reference or anything useful for it
the calculations are incredibly easy, but there is not enough reference material for a 'hello world' type of thing
zealous moth
you're right clicking in the void. Click and drag from the blueprint node "cast to". Then it will show you "target vars"
watch your tutorial again and check the exact mouse movements
when you drag from other nodes, you get node specific context
why in the world would you get a private var from another bp out of nowhere?
supple root
I don't know, ue4 tutorials dont explain why you do things like they just show pictures and say 'copy this'
supple root
I dunno, Unity was super easy to set stuff like this up, I got farther in an hour than I have in 3 weeks here (though Unity has it's own issues that make it unsuitable for this project)
zealous moth
the problem with unity is that it is too bare and you have to program everything. Anything you make in unity, you can make in unreal in record time.
if you still cannot see the var, make sure you compile the bp you are casting into
supple root
how so? I found the exact opposite
blueprints are just a crappy way to program things
but either way that is besides the point
zealous moth
bp is literally the same logic as typing without the human error factored in.
supple root
it seems like it would be safe to assume that this tutorial was, at some point, functional
but there is a blue box that says 'target' on the left and 'camera' on the right
but nothing says what that blue box is, what action it is doing
and since it's just a screenshot with no project I can't right click it or do anything to find out what it's doing
so my only recourse is to ask here, or instantiate EVERY SINGLE BLUEPRINT ACTION until I find the one that looks the same
zealous moth
that is because the "camera" variable is specific to that "target" being the "cast to" target. You click in the pin (the blue circle) and drag out. Then a new context appears that is specific to that cast. That's what you're seeing.
supple root
I dunno, I just don't have the option that he gets, it must be a version thing or a missing step or something
zealous moth
@vital pike this is one of the intrinsic contradictions of UE4. The logic is that character BPs will hold all their available commands and if you need to change characters, the new character you possess will hold its own set of moves. It honestly does not matter but there are input fatal error issues when your pawn is destroyed for whatever reason.
If you have a need to swap pawns, use a character scheme; if you use the same character, use a controller scheme.
@sour raft "isinputkeydown"
@vital pike typically the logic is this:
Game Mode sets up what the controller is
The controller is the player and can contain any input. This is usually not destroyed. If a pawn is defined, the controller possesses it
The pawn acts out all commands given by the controller (you).

Is there a standard way for handling references to abstract actors in the scene? For example: When my character places a unit in the level, he offloads that function to a unit placement manager which is just a blueprint sitting in the level. It actually handles spawning and placing the unit, etc. My question is about how should my player get that reference to the unit manager? Is it better to have the player character do a "get all actors of class" on begin play and find it, or should I have the unit manager register with the game mode and then have the player character ask the game mode for the reference to that unit manager?
pale epoch
@stuck hedge since each player character is only finding the unit manager once I doubt performance is a consideration. Using "get all actors of class" sounds more simple, so I'd go with that unless there's a reason to refactor it.
stuck hedge
I didn't really think there would be much of a performance issue. It is a single player game. I just wondered if there was a standard way to handle this kind of thing.
I was thinking about the idea of how maybe a game mode or something else should act as the go-between for all the disconnected actors in a scene that might need to talk.
pale epoch
Yeah I dunno. I went through a similar exercise ages ago so I don't remember the outcome, but I don't remember finding a clear answer either.
I suspect there isn't one, but someone with more experience might know.
I have a new question 🙂 AI Controller has a 'MoveCompleted' event. Is there an equivalent for 'RotationCompleted'? I'm using AI Controller.SetFocalPoint to rotate my characters, but I can't find a built-in method to know when the pawn rotation has finished.
stuck hedge
is rotation considered a move?
pale epoch
No I don't think so. Move is just to a location.
pale epoch
Start an animation.
I'm contemplating making my own event in C++ to use from BP but I'm not keen to reinvent the wheel.
stuck hedge
The only immediate solution I could think of would be to check your look at rotation and compare it to your existing rotation (maybe yaw only) and go off that.
is it taking a really long time for them to turn and face the way you want?
zealous moth
@pale epoch you can make it so that when the location is reach, force the rotation via rotate actor and look at nodes and then make a check that the look at and forward are the same
@stuck hedge if your want to pass on references for the player, I recommend either the GameInstance or the PlayerController
pale epoch
@zealous moth thanks, I'll have a play.
stuck hedge
@zealous moth Game instance is persistent across the entire game. When the level changes those references would no longer be viable. My player will be going back and forth between 2 main levels so when that happens those references will be wiped and while the player character in the other level wouldn't be accessing those references, I would have references sitting in memory that are not valid any more. As for player controller, it doesn't make sense for the player controller to be interacting with much beyond the player character itself and maybe the game mode. It really shouldn't be talking to other random actors in the scene without good reason.
zealous moth
well... otherwise, use the save file and store those references
stuck hedge
I think you're not understanding the scenario.
There is no way using the save file would be remotely appropriate in this situation.
When a character interacts with something like a door in a level there is an overlap or line trace or something that gives your player character the reference to that actor so that he can do whatever with it.
but when we make actors in a level like managers or whatever, that don't have physical form, there is no way for a character to get a reference to that directly. They have to use a function like "get all actors of class" and find the one they want (usually only 1 anyway), or some similar method to find it and save a reference.
my question was regarding a standard method for getting that reference to the player. Whether it was better to have the player character to do "get all actors" for the various references it might need or if those manager style actors should register themselves with the game mode on begin play so that the player (and any other actors that might need those references) could get them from a centralized place.
the save file cannot be used to save references to instanced versions of blueprints.
I guess it could..but it would be meaningless since those instances would change when the level changes.
There is no reason for these references to persist across level changes.
zealous moth
well... what you're trying to do is top down; as in you are trying to find all your actors.
You can always do it bottom up: on beginplay, each of those actors can declare themselves to either your character/controller/whatever that wants to know.
Storing them in memory would work best imo but if it doesn't apply to your game, then it doesn't.

Gentelmens im a bit stuck. Lets say we have a BP where we:
- Create dynamic material instance and assign that material to mesh inside those BP.
- We create RenderTarget and put it texture to our previously created dynamic material instance.
The problem: if we use construction script, when we move our BP and place in on the level it will constantly creating a huge lot of render target textures which will cause RAM overload.
If we create dynamic material instance and rendertarget texture on EventBeginPlay - it works but only at runtime.
How i can achieve render target updating in editor without those problems with creating too many unused textures?
And no, i cant create rendertarget by hands. It should be happened automaticly in BP.
mild ore
you can disable blueprints to run constructions script when moving the object that may cut these trashing quite a bit
also, try create a rendertarget asset and assign to your actor by default, which probably wont recreate it any longer. when you run the game in beginplay assign a new rendertarget so it can be unique.
past swan
you can disable blueprints to run constructions script when moving the object that may cut these trashing quite a bit
@mild ore Oh im complitely forgot about those one. Yeah, it cuts a bit of RAM problem. Sad part what changing variables still run construction script and they spam rendertargets to RAM :(
Unfortunately, if i create any "default" RT and assign it, it will works only for 1 actor, or for several actors simultaneously, which will not provide realtime in editor pipeline.

Currently im using event tick to trigger a line trace which tells me what actor im looking at. Used to show popup messages when looking at different actors. the problem is the popup animation is being triggered constantly because its on event tick. How can i get it so when i look at an actor this only triggers once. And then cancels the animation when i look away?
mild ore
@past swan store the reference for the new rendertarget, and check if its valid before creating a new one. just assign the old instead. i think it will remember.
you can also expose a button on the actors panel (event run in editor) and trigger a creation of rt, but that may require you to press this button everytime you load the level in editor
tight schooner
@ripe turtle Store the actor into a variable. Do a check if the traced actor is the same as the variable before executing the rest.

hey bp'ers sorry to interrupt but i was wondering why this sequence node is only firing the first pin and not the others :/

@past swan store the reference for the new rendertarget, and check if its valid before creating a new one. just assign the old instead. i think it will remember.

Maybe you can do something with a Do Once node, so it only triggers the first time. And if you want, another exec pin can reset the Do Once gate if you want it to retrigger the next time.

Im trying to make the character's active camera switch between 2 characters but im having trouble because they require a refrence to each camera but they are in diffrent character blueprints
stuck hedge
@old prism So you need to use something to pass the reference between the two characters. If there is no way for them to directly connect, e.g. via an overlap, then you should use the node "Get all actors of class" or use your game mode to store a reference to both instances of the actors and get it there.
after you have the reference of the correct type you should be able to pull off and get their camera manager.

Hi All, apologies if this is in the wrong channel but I don't see one specific for UI/Widget
When creating screen widget/menus etc. what would be the best practise for this in terms of scale/resolution and being able to change window size and keep everything aligned.
The reason I ask this is I'm having a few layout issues when changing size of the window when the PIE or game is loaded, in the default 1280x720 view in design mode its all fine and when the PIE launches in 1280x720.
Would you start at 1280x720 ? or something higher, the target platform will indeed be "PC Desktop Based" and ideally 4k but bare bones 1920x1080
Any pointers on this or help would be really appreciated.
Thanks

UMG is your general UI channel. But in general, just try to design on the scale you think you'll end up with the most. I'd almost say design on the platform that you think will be the largest but I don't personally have a lot of design practice with multiple setups yet. But in general, scaling down is a lot easier than scaling up.

do you guys have any idea to stick a ragdoll to a wall after shooting it with an arrow/bolt
maiden wadi
Not a clue. But if I was to go looking for how to do it, I'd start with applying a constraint to the ragdoll and bolt. Onhit or overlap, check if the hit actor was one that can be ragdolled or should be ragdolled, or whatever checks you need to make. Let it keep going though til it hits an actor type that you can stick the arrow too and just attach the arrow to that actor and keep relative location. Not sure if there would be issues, but it sounds like it'd work. In the end you'd end up with a physics body that has a constraint to a projectile that's attached to another actor like a wall.

I have an abstract blueprint base class with one sphere mesh in it and two float variables. The Mesh is called Influence and the variables are InfluenceStrength and InfluenceSize.
I have a child blueprint class that inherits from that and has a plane mesh with a material on it, just a little graphic.
It seems that whatever I set the parent class InfluenceSize to, the child class's plane mesh's scale, all 3 of them, automatically get set to the same value as InfluenceSize. Manually changing them per instance does nothing, it forces the values back to all be the same as InfluenceSize
Yet InfluenceSize is not referenced anywhere. I am not using it whatsoever at this point. (which seems like I must be wrong, but listing the references gives nothing)

Just wondering if I'm doing something wrong here?
wise jewel
where can i see an example?
tight venture
you want to create a blueprint pawn at the same location as another actor?
wise jewel
if you mean using reparent is not wha i mean
i mean the class
if i add a character bp inside i alreadty have some stuff
tight venture
i'm pretty noob too, but I've used that before
I think what you want is "Spawn Actor from Class"

i think you didnt understand what my question is

I've never used CharacterMovement before. I'm more noob than you. But it says on the docs that it comes preattached to an ACharacter actor

You can't add a character movement to anything that isn't a character or something inheriting from it. It's just an actor component that's specifically designed for the character class.

Is there an easy way to see if any of the actors in the array match the variable
ionic harbor
reposting with some additional info
I'm working on an AR app and I'm trying to make a scanned image perform a specific task. The caveat is there is more than one image tracked, and more than one task. so scanning picture 1 debugs one print string, and scanning picture 2 debugs another
[2:39 PM]
Anyone have an idea how to do this? my current blueprint is just getting everything
[2:40 PM]
The current blueprint gets all geometries and casts as AR candidate images (there are 2 in the AR session config.). What I need is to then go through them somehow and match them to a specific candidate. I can't even seem to reference candidates!
so I have these candidate images that are being tracked in AR, and I can get tyhe candidate image object. Does anyone know how I would compare a candidate object reference to another variable, to see if they are the same?
this is what I'm doing now and it seems insecure and silly.
the variables are right there, but I don't know how to reference them. so i'm instead going around the problem and comparing the display name to a hardcoded string that I'll put in. this seems sub optimal, does anyone have an idea what they would do?
grim stirrup
In your pic, you have "if the object in the array = nothing" Have you tried maybe setting up an enum of possible thingies? (I don't know AR or what you're using).
lament shuttle
Hi, I'm trying to debug something using the Blueprint Debugger window. I'd really just like a list of executed events, but the Execution Trace lists just gets overwhelmed by stuff running on Tick. I can't put breakpoints on events cause my bug is comes from something very finicky/fast input related.
How can I get a list of specific events executing without plugging Print nodes on each of them?
ionic harbor
Lord Xtheth, I started using blueprints a few days ago, so I don't know what an enum is in this scenario. But the main thing is that I don't know how to use my candidate image as a reference in this blueprint.
If you are returning a object of type foo, and you want to know if it is one in a list of foos, how do you instantiate that list of foos.
In this case, foo is "candidate image," which is a data asset meant to hold information about an image for AR tracking.
dragging the actual candidate image into the blueprint gives me nothing. adding a variable and calling it a candidate image gives me nothing. I just don't know how to handle the blueprint system doing this
lunar quiver
Hi @unique flicker . Do you want to spawn an actor at the location of a socket?
OK so you have this skeletal mesh in the level?
I do not understand the problem, if you could provide some more details of exactly what problem you are experiencing.
OK so the physics asset will only collide if the mesh is simulating physics. So either you have to call 'Set Simulate Physics' for the mesh, or more likely, just to detect overlap, you have to attack a collision shape (ex sphere) to the mesh, and set its properties to enable overlap.
For the Overlap event, you will need to do the collision shape thing. Have a look at this:
https://youtu.be/zZPyMjEWpF8
ripe turtle
I am so confused at to why this effect the default visibility of the progress bar... Its set to hidden as default and when i start it up its visible and visible nor hidden were ever printed
if i unbind it is hidden
but when i add the bind back. even if i disconnect the return nodes. it is visible
lunar quiver
@ripe turtle Add some prints to the Cast Failed outputs as well, maybe the code is not reaching your return nodes.
ripe turtle
btw the cast to flashminer fails until i look at it
not sure if that matters
but if the default state of the progress bar is hidden why should it matter
lunar quiver
Default visibility is probably Visible. That 'hidden' you set is probably ignored, because it is only looked at if you did not Bind your own event.
@cursive yewdii Overlap events will not be called because there are no overlap. Physics assets with collision shapes do not intersect eachother.
@cursive yewdii Because you used On overlap, I assumed that is what you wanted - overlap. If not, you might look into Hit events instead.

Im trying to figure out how to detect what im looking at best.

@ripe turtle kinda depends what you're trying to achieve with the trace, but usually a Blueprint Interface lets you consolidate a lot of individual class casting by making a bunch of random classes share certain functions. (Class inheritance is another way to do this but BPI is arguably more flexible.)
There's probably a Matthew Wadstein video about Blueprint Interfaces

Heya. Is there any settings I might have overlooked that may prevent a pawn or character from receiving any of my InputAxis events ( 'AxisValue' are null, like a LookUp/TurnRight). It's called both on the controller and the controlled pawn but the controller doesn't block input nor consume any of those inputs. I don't get it. As soon as I delete the InputAxis from the controller, it works again
jeeeesssuuuuss I just found it. Those nodes 'GetLookUp' can consume inputs as well... man. I've been searching for an hour

@blazing ridge Most likely yes. You're changing the source file, so the engine needs to replace it in all of it's locations. Try to plan ahead for anything you'd need to use structs for.

stoic root
Hello there 🙂 I'm trying to learn the UE4 and so, I started my first little project. It should be an endless runner where you have to dodge cubes as a spaceship. The most things are working pretty well, except the collisions. They just don't work for me and my tiny spaceship flies trough the cubes.
I tried to add collisions to the static mesh, the cube in this case by using collisions -> add collission and the "Convex Decomps"-button. Both havent worked for me. I also tried to turn on the physic simulations. In this case, the collisions worked, but my spaceship moved the cubes 😄 Also not exactly what I wanted, but funny to observe 😄
For the generation, I have this blueprint. I'm following along this tutorial: https://www.youtube.com/watch?v=sNueIWCKoco
The "Add Child Actor Component" is refering to this simple blueprint
maiden wadi
@stoic root Anything that you want to use general collision on, don't use a default Scene component as the root. Change that to one of the collision volumes.
honest forge
Hello, does anyone have any advice on the best way to make an object move to the centre of the player’s character, then disappear after interacting with it?
covert stirrup
@honest forge Get the world location of your player character, and use that as a point the objects are attracted to. On BeginOverlap, destroy actor
maiden wadi
If you already have a reference to the player character, doing distance math on a timer is a little safer.
stoic root
@maiden wadi thanks for the answer 🙂 Have I understood it corectly, that the collisions don't work because i'm using the default cube in the box-blueprint? And do you mean with your solution this one here?
maiden wadi
@stoic root
honest forge
@covert stirrup thanks for the response. I have tried to use the player’s world location as the end point with a timeline, but the object moves to a place far behind the character 😩
maiden wadi
Or the other Collision one. Either way. But don't use a moving actor that has a SceneComponent as it's root for actor overlaps or Hit events.
@honest forge What is the other object? What is it you're trying to make move towards the character?
stoic root
@maiden wadi I tried to replace the DefaultSceneRoot with both collisions, but it still doesn't work. Thats how it looks like right now
maiden wadi
Show me your overlap or hit event?
stoic root
Where can i find this?
ah wait
@maiden wadi I haven't specified an overlap or hit event. I think I have to do this, the engine doesn't this by itselfs, does it?
maiden wadi
@stoic root Well, sure. The event probably still fires, but if you're not letting it run on your actor or telling it to do anything, it won't do anything. Or are you just trying to use physics collisions to simply stop the ship when it runs into something?
hardy sentinel
Why there is not a macro For each Loop that iterates/output the element by reference instead of values in Blueprints? Or it doesn't make sense to do that?
maiden wadi
@hardy sentinel If you really need a ForEach loop that sets by ref, just make one. All you need to do is copy the current ForEach loop and replace the GetCopy node with a GetRef node and change the output.
stoic root
@maiden wadi yeah, that makes sense 😄 I just tested the event a bit. The Event doesn't fire if my ship overlaps with the cubes. It only fires when it overlaps the collisionbox to load the next parts
hardy sentinel
@maiden wadi Yeah i know, just asking if it makes sense to make one or not(and use that instead of the by value one). I mean.. it will improve performance in BP's? Or it doesn't matter due to some limitation or thing that i don't know about BP's
maiden wadi
@hardy sentinel Hmm. Not sure. Let me try and see with a quick test.
@hardy sentinel There is only about a 2% increase with the ref one.
hardy sentinel
uhmmm
@maiden wadi thanks for the test, maybe the + operator is receiving a value?
maiden wadi
Is receiving a value?
hardy sentinel
don't know wait
i don't know if all the circles mean value and the diamonds mean by reference. Is that true?
well it doesn't matter.. 2% is very small
maiden wadi
Yes. Those two tests are doing the exact same thing. One is just setting by array element, other setting by ref.

You have to play it in reverse too. Maybe on end overlap.

I have a sun that's rotating around the scene and I want to do things with objects that are not in shadow

@covert stirrup The mesh surface of an actor. What I'm going for is a plant being hit by sunrays - depending on how many rays hit it, I add X to its growth for example
covert stirrup
Hehe, I assume you meant me! xP. Rather than raying out like it would in the real world, make the sun get references of all actors it would need to affect, then get the distance between V1 (Sun) and V2 (Planet)
Using the distance, you can calculate the inverse square law of how much ray would hit that planet given the distance, with the size of the planet / sun respectively
You could use a line trace every so often to see if the planet is occluded by any objects
carmine prawn
@latent junco something like this might help. Search online for more stealth tutorials if that doesn't help.

@tight venture Is this for mouse or screen touch?
tight venture
touch. here, let me post a pic of my blueprint section that illustrates
If I use the Released pin, I get 0 values for both the Location and the Impact Point
I looked it up, it's because there is no "hit result" on Released (because no finger is on the screen anymore, that makes sense...)
The Return Value from Get Hit Result Under Finger on Channel is false on Released
And that makes sense, sure, but then that still begs the question, how is this done then?
trim matrix
how can get all the objects in a range of the blueprints and reduce their distacnce
maiden wadi
@tight venture My initial guess would be something as simple as on pressed, start a timer that updates a hit struct variable. On release, spawn actor at the last valid point?
maiden wadi
@trim matrix Reduce their distance? Getting the actors is easy, just use SphereOverlapActors
trim matrix
i mean bring them closer to the center of the blueprint

@trim matrix you need to clarify your question

@trim matrix That sounds very similar to what I need to do. I haven't finished it yet, but basically, I'm planning on doing this (and it will work, pretty sure). Model it after the Newtonian gravitational equations, where the "pull" of one object on another is determined by multiplying it by mass/radius^2. Just use a BP class for anything that exerts "gravity" and give each one a "strength" (mass) variable, and then calculate the distance between the actors for the radius, then move your actors accordingly
trim matrix

That's the gravity actor.
This is the physics actor I was testing with.
trim matrix
thanks so mutch
maiden wadi
You might not need that much force on the multiplier either if you disable gravity. But with gravity I needed that extra zero to get it off the ground.
Bear in mind, I'd add some checks in there, like on the loop to check if the component is simulating physics before adding force, stuff like that. But for test, it worked.

I have an state in a state machine in an animation blueprint, is there a branch-like node I could use in the state?

@winter kettle What do you mean by in the state?
@unique flicker Just add that specific collision sphere's event overlap to your graph and use it instead of actor overlap. You can do that by clicking on the sphere collision component in the Components area. Right click on it and go to AddEvent, Add OnComponentBeginOverlap. Other way is clicking on it and scrolling down in the details panel until you see the green buttons to add events.
@winter kettle Are you in the AnimGraph or a StateMachine?
Isn't that what you just did with the bind?

yea no that's a completely fair fix tbh
so it sounds like you are binding on the first overlap yea?
hollow cape
You should be binding on spawn
covert stirrup
^ +1
These are bound on Event : BeginPlay, so when it is triggered it will always know what it's meant to be
hollow cape
@unique flicker , just to make sure we're all on the same page here. You spawn/pick up the weapon. Immediately after, you should do a get "mesh" (or whatever you've called it), drag off that and "Bind Event To On Component Begin Overlap"
Delegate that to a function/event on your character BP, and it will fire there
maiden wadi
Only if you want to handle that in the weapon blueprint.
covert stirrup
you could use BPI if you don't want to bind
hollow cape
Yep, I mentioned BPI and dispatcher as other options
Or just directly calling a function
covert stirrup
Begin play will bind once, at play to what ever it is told to be bound to
if you change the cast half way through without updating the bind, no
hollow cape
when you spawn the weapon, give it a reference to the owning actor, and use that ref to call the function on the character BP directly
covert stirrup
@unique flicker I am doing this very thing in my project right now, I will show you my use case. maybe that will help you out
