blueprint

[drowsy veldt]

That is, there's a queue system, but it's executed on the main thread.

[runic parrot]

that trashes all the benefits of using async calls 🧐

[drowsy veldt]

You can still take advantage of the throughput limit

[final lava]

yea, I mean, it is possible in classic way without any problems but I am trying to use latest Enhanced Input Plugin that has much more nice features.

[drowsy veldt]

Yeah, events are not executed off-thread.

Or rather, each specific event is fired and executed on whenever the programmer that fired that event feels like.

[gusty axle]

ive fixed the issue
i just installed a Runtime PhysX Cooking plugin lmfao

this

works on cooked project too

[covert schooner]

When you do what is Print Screen in C++, you can control the amount of time the message persists for, is that available in blueprints, or do I need to expose it more with a BP helper?

[gentle urchin]

Yes

Let's say I'm playing a in-place animation that changes the player's location. And I want to use MoveComponentto on the player to keep the player at the end location so when the animation ends the player doesn't snap back to the starting location.

[hollow gorge]

Hi, I'd like to build some menu navigation with the integrated focus system.
The goal was to have mouse over and keyboard navigation change focus between individual buttons, I was considering using the "Event on added to focus Path" on each individual button but I can't seem to find this or any events for my custom button class. Should I be using a custom event for this functionality or is there a better approach? I try to avoid ticking if possible.

[hollow gorge]

Solved, It seems like can achieve this functionality by using a custom widget that contains a button.

[cyan bone]

How do i clamp a value to a minimum of 1 and maximum infinite?
I have an integer that i need it to be at least 1, but Clamp needs always Max. I need it to make sure it becomes if it is 0. But no limit on the max.

[lucid lynx]

Create a pure function that just if(Int<=0)return Int=1.

[cyan bone]

That worked. Thanks.

[cyan bone]

yup that also works and its more simple

[wild crater]

Is there an easy way to convert a spline (or a set of points) into a mesh?

[onyx token]

i wanna hold rightclick, and as soon as my "i get stunned" animation is over - i wanna move to the block animation

[grand briar]

I need a good way to trace to the nearest surface to an object. Not sure how to go about it

[deep elbow]

sphere trace and set start and end to be like 0.001 away from each other

then see where the sphere overlaps?

and a sphere radius as big as it needs to be for your uses

[grand briar]

yeah i was thinking in any direction. i havn't used sphere trace before it confused me a bit. i'll check it out thanks

any "visible" surface

[worthy tendon]

not sure if sphere trace would give you accurate results to your problem but might be accurate enough

[deep elbow]

he doesnt know the object

i presume, otherwise bit of a wierd Q

[grand briar]

yes, i mean any object. i just want to find what is closest to me, the point of any surface that is closest. and then i want to get the impact normal

[worthy tendon]

@trim matrix but center of the object could be further from you. for example tracing inside a mug, nearest surface is edges of the mug not inside of it

🙂

it depends on where you start the trace, you can try multiple sphere traces and get the closest hit but that might not be always correct

[grand briar]

hm, only problem i realized is i need to do it on a plane. (only x,y and not z)

[deep elbow]

you might need to just spray a load of line trances in a circle around your character, like, not that expensive

or tag things you want to overlap with the spehere

and ignore everything eklse

[grand briar]

i started doing that, but i wasn't sure how to get the average impact normal between several hits for accuracy. then i figured maybe i rotate a line trace around like a scanline really fast. seemed dumb but i guess that could work?

[deep elbow]

yeah depends how often you do it and how much stuff happens with the info you get from the trace i guess?

[grand briar]

only worried that it might "jump" over smaller objects if it's rotating too fast. can't have it too slow either

[lofty jungle]

can anybody help me? I have created a health bar on top of enemy pawn/character, and am trying to bind the percentage, but i dont know what to plug in to the cast to wildcard. I have tried promoting to variable and plugging in the reference but im getting errors. I think it might be because the AI is spawned in and not existing on begin play until 2 seconds later, but not sure.

[deep elbow]

where does the widget get spawned from?

you could pass in the owner as a ref if the alien spawned the widget

otherwise which alien is it supposed to be getting the health from? it doesnt know

[tawdry surge]

Or don't use a binding at all and just call an update health function or event when it changes

[lofty jungle]

The widget is a component of the enemy alien actor, so yeah the alien spawned it i think. I can see the bar, but its just stuck at zero. Which node/s do I need to pass in the owner?

[deep elbow]

uh, you could create a variable in your widget with the class of your bp_alien, then expose that on spawn and pass it in to the widget from the bp_alien

[lofty jungle]

i tried get owner, but error.

[deep elbow]

but eh, im ill, so my brain is not firing correctly

[lofty jungle]

ok ill try that, thank you. im pretty new to game dev so a lot is unfamiliar to me at the moment.

thank you i will watch them now

[lofty jungle]

Worked like a charm, i found it really helpful to know to keep it in the character BP instead of bind it in the widget BP. Thanks so much 😄

[deep elbow]

awesome, glad it helped!

[grand briar]

so i'm not sure how to go about this. made a sphere trace. this is the result. this way it doesn't work well to find the closest surface

[tawdry surge]

Looks like you're just doing a regular sphere trace. If you do multi sphere trace instead it'll return an array of all things hit and you can evaluate which is closest

[grand briar]

ah, handy

Hi all!

I have this blueprint for a decrease hunger event and i want to hook it up to a progress bar on my UI. I have the progress bar set up and ready to go and the HungerLevel variable is attached to the FirstPersonCharacter template i have. How can I make the progress bar on my UI read the hunger level from the player?

because the HUD that shows the hunger level is going to be removed and recreated on the viewport on the fly as menus are navigated between, i don't want to do the whole math on the UI blueprint

[deep elbow]

you get a reference to the widget in your player, you update the widget when you update hunger

make a function or custom event to blibbidy-bloop the hunger

[runic urchin]

I'm looking to select all static meshes underneath Exterior, how would you go about it

[jolly cairn]

awesome, will give that a try, thanks!

[tawdry surge]

Open it, select the top one in the folder, shift click and select the bottom

[runic urchin]

I'm looking to select them or sort them into a group in a blueprint to force an lod

[deep elbow]

at runetime?

lol rune time

[runic urchin]

yes

[deep elbow]

cant you get the parent and get children and add them to an array and run a for loop on that shit

[tawdry surge]

You could use tags, but I don't think you can access them by folder in the world outliner

[runic urchin]

I've gotten as far as get children compents

and then able to filter by static mesh components

[deep elbow]

?

[runic urchin]

the only thing is that static mesh components

[deep elbow]

i mena, what are you trying to do

[trim matrix]

Hey is there a way to draw lines on the screen within a widget?

[runic urchin]

I'm trying to get all static meshes in a certain group and force LOD

[jolly cairn]

this is what i have now, the hunger progress bar does not deplete. Set Percent should be the right function to call, right?

[runic urchin]

the other thing i'm trying to do with it is trigger a forced LOD when inside a trigger zone (that code I already have)

[jolly cairn]

im being dumb, im not telling my event to start XD

[deep elbow]

yeah, but thats uses a 0 - 1 value i think, so check what your float is, maybe its 0 - 100

ah

[jolly cairn]

ok the actual number ticks down but not that bar...

[deep elbow]

i find it weird that just getting children and casting to static mesh components wouldnt work

[jolly cairn]

righttt, so will need to divide by 100 then

[deep elbow]

what gets returned when you try, do the casts fail? do the lods simply not update

[runic urchin]

Casting to static mesh components is not finding the force LOD

[icy dragon]

There is a Draw Line node for widgets

[jolly cairn]

@deep elbow working perfectly! thank you very much for your help 🙂

[trim matrix]

That doesnt work for me. Only when i replace the onpaint function

[deep elbow]

great!

[runic urchin]

this is getting all children components of my exterior group

[deep elbow]

yeah, head issues with checking class like that, thats why in my image i just casted to the componenet, does the sdame thign right

that should work

is it possible to read from a JSON file with blueprints? i want to store the inventory contents in a file and coming from mainly doing .NET stuff in Unity, I've always done it with a JSON file. Should it be handled the same way in UE or is there a better way?

[idle vale]

Why did the Set Max Distance exist as a node & not the Set Min Draw distance ?
That the one i absolutely need...anyone have an idea/ solution to bypass that ? or maybe i'm missing something.

[willow gate]

Uh, ok just started messing with UE5 and the FPS template is strange the way it uses an event dispatcher to fire the weapons. My question is, are the event dispatchers not replicable? Cause I'm having a hard time replicating the projectile spawning.

I can just fix the problem another way but I'm just curious now for future reference, if there's a trick to replicating an event dispatcher call from another object

[steel shadow]

What happens if I call a 'timer by event/function name' at a higher frequency than frame rate allows? Does it then just execute per minimum ms interval?

[solar bison]

fire the event dispatcher in onrep, so then every client gets that event when whatever you need has successfully replicated

alternatively if you aren't using onreps, then you're probably using a multicast. Fire it in the multicast

[lost wyvern]

My geometries made with Geometry Script for UE5 disappear when displaying in standalone or after packaging, but you can still see them in the editor and in PIE.
Any idea why this is happening?

[willow gate]

hmmm.. ok. I'm not sure I know what you mean but I'll do some research before I ask any more questions.

does anyone know any tutorials for side scroller object grabbing? im trying to get my character to animate grabbing an object but i dont know how to make it

[real notch]

I keep having issues with accessing "none" on actors I cast and store references to in beginPlay. I understand why it's happening, but it's a bit annoying. Is there a step after begin play? Like how unity has awake and start for example? Some place where I can be sure everything (actors, game mode, game state, player controller, player state) exists and is ready to find?

[calm citrus]

Can anyone explain to me what this is doing? Trying to wrap my head around some of the BP's in Advanced Locomotion v4. I understand what its meant to do but im confused what all the wiring is doing

[dark crow]

It's just a double tap logic based on on gates

or i guess it's a hold logic

Shortly releasing closes the upper gate and triggers tapped but only if you didn't trigger hold
Holding it will enter the first gate and return held closing the released gate ofc

It's a Macro so it remembers the states

[grand briar]

So.. i've managed to get the distance of all the hits.. i'm trying to get the closets surface's impact normal but i'm not really sure what to do from here. quite new to arrays so.

[faint pasture]

Make a function that takes in an array of hits and returns a hit

Loop over all the hits, setting a local variable ClosestHit if the distance is less than the current ClosestHit or it's index is 0. Return ClosestHit

Or rather, set ClosestHit = Array.Get(0) then do the looping.

[calm citrus]

Ok so I am understanding it slightly. Im going to continue to study what you said. But I am also trying to implement this in my game. So the Macro from before is the Hold Input and the tap works perfectly from changing from walking to jog. But Im stumped on the held input and trying to make it to where when the player is no longer holding the button they stop sprinting and return to the previous state...

[dark crow]

It doesn't do that

You would need to get rid of this

That closes the Released gate

[calm citrus]

so get rid of it all togther?

just that input

[dark crow]

If you want Released to always, trigger, yes

[grand briar]

Oh man :D. let's see if i got this. thanks for the info though i'm gonna give it my best

[calm citrus]

Dude thank you so much it worked perfectly I am definitely gonna study this so I wont get lost later on

[faint pasture]

Do you follow the logic?
Look at hit
Is it closer than the closest one so far? It's now the closest.
Done? Return the current Closest

[dark crow]

You may wanna change Tapped to Released so it's clearer to you what it does now

[calm citrus]

Will do thank you so much

[grand briar]

yeah, it's the execution i'm worried about

[dark crow]

Just keep in mind that at that point you don't even need the Macro, you can just use the InputAction flow directly

Doing this is the same if you make that edit

[calm citrus]

huh you're right... lol I feel like an idiot however there is one problem

[dark crow]

The Macro like you had before is useful if you want to keep continous input till you press again

Let's say I have a sprint key, I hold it then release, it will keep me sprinting till i tap it

Like in most modern FPS I guess

[lime moat]

anyone know if its possible to change lock/rotation constraints at runtime using BP?

[dark crow]

With the edit you made it's only good if you wanna have a chargeup ability of sorts

For example I need to hold the key for 5 seconds for me to sprint and when I release it goes back to walking

But at that point there may be some more logic in between

[calm citrus]

Ok cool I'm writing this stuff down in my notes. I do have one more question if you can answer it.

So for the input I just used like you said. I don't know how easy it is you can tell. But the input reads my toggle at the same time as its held. Making it to where if I stop sprinting it goes to the next toggle action. Is there a way to make it if I stop sprinting it will go to Jog mode instead of going back and forth from jogging and walking

I dont know if I explained that correctly

[grand briar]

Would you say i did it properly? i'm trying it out now just gotta draw debug and all that

[dark crow]

You can use some bool logic if needed, really depends on how you want your run / jog / walk flow to go

[calm citrus]

I basically want my sprint action to always return to jog state. Never the walk state

[dark crow]

And how would you go from jog to walk?

[calm citrus]

with the toggle I use now

[dark crow]

Use a bool then

bSprinting

If you sprint it sets to true then on the toggle it checks

if bSprinting True then Jogs
if false then Walks

It will be true only if you sprinted prior, if not it means you are jogging / walking

FlipFlop is basically do A then B and repeat so not really useful in this case

[calm citrus]

I swear I feel like an idiot more and more I go deeper in UE lol

thanks for the help

have a lot of notes

[dark crow]

You may wanna have a bool for each state just in case if future things can impact that

bWalking
bJogging
bSprinting

And you can create functions to change states

For example SetWalking where it edits your speed and sets bWalking to true and you can do whatever you want in there related to the state change

[calm citrus]

Would it be easier to use enums? I have enums to transfer me from walking to crouching

[dark crow]

You can totally yeah

Whatever feels most comfortable

[calm citrus]

Cool, thanks

[bold shard]

Weird question, I have a BP with several components on it. I can modify all of them, and I can save my BP, but when I reopen the project one of these components resets (a cube I use for some collision stuff). Anyone have any ideas?

[flat coral]

This is stupid but try closing the editor tab before exiting the editor. It can force a "real" save for materials at least, probably works on BPs too

Also does anyone have any idea how I can figure out what class is still referencing this deleted class?

Clearly something has it as a parent but i have NO IDEA what

And weirdly nothing is breaking in game

Actually that's not weird, I replaced the parent class with a component system before removing it

[surreal peak]

Hm

You could try to run the compile all blueprints test

And see if one cries out

[flat coral]

Where is that?

[surreal peak]

I usually do that via command line and I'm on my phone so all I can suggest is googlung for this ):

[flat coral]

ahh fair

UE4Editor-Cmd.exe MyGame\MyProject.uproject -run=CompileAllBlueprints

[surreal peak]

Command line is something something UE Editor.exe projectname.uproject -run=CompileAllBueprints and then some optional settings

Yeah, memory on point today

[flat coral]

nice

[surreal peak]

There are some ignore folder things you can do

Not sure if needed

[flat coral]

OH hold up! I just figured it out one sec

[surreal peak]

This also exists as an ineditor test with UI but that's a longer walkthrough to get access to that

[flat coral]

This is useful general knowledge: If you get that error, you can mouse over "inheritablecomponenthandler" and it says what it ACTUALLY is

[surreal peak]

Nice

Well I would recommend the command line anyway

It's a strong tool to find broken bps before submitting to P4 for example

[flat coral]

The fuck? The class this references doesn't have that missing BP as a parent AND neither does its parent. The missing class is nowhere in the tree.

[flat coral]

Wait do I run this in the UE4 command line or like the windows command line?

[surreal peak]

Windows

[flat coral]

oh weird

I'm shit with the windows CLI lol

[cyan bone]

I need to remove a range of indexes from an array.
So i have an array of vectors. And sometimes i need to remove items from 3 to 9. So remove 3 4 5 6 7 8 and 9.
Other times i need to remove in the opposite direction. for example from 7 to 2, remove 7 6 5 4 3 2.
How do i do this?

[mental trellis]

Is there some reason you want to remove them in specific orders?

[cyan bone]

It doesnt need to be removed in the order exactly. Only the range must be removed. But i had to say that sometimes the range comes in reverse.

[mental trellis]

If the range is in reverse, just reverse it and use the same method as before.

Is it always a contiguous set of indices?

[cyan bone]

yes its always like from 2-9 , or 7-19, or 17-5.

[spark steppe]

for loop

iterate from max index to min index

there are math min/max nodes to determine the lowest/highest index

[cyan bone]

so it works both ways? i dont know why it is not working. i must be doing something wrong

[mental trellis]

Does the order of the array matter?

[spark steppe]

well, you have to remove from back to front

[cyan bone]

from back to front? You mean like as we do in a reverse for each loop

[mental trellis]

What I'd do is something like: count = end - start + 1 for (index = start; (index + count) < array.size; index++) array[index] = array[index + count] array.setsize(array.size - count)

instead of the min you could check for going past the end of the array

It is simple ✈️

[late gorge]

by event didnt work either

[gentle urchin]

Are you sure its executed?

Tried a print string?

[late gorge]

yes, i've confirmed by setting a break point

the set timer definitely happens

[mental trellis]

You can do a cross product of A->B and A->point (assuming 2d plane,) the 3d coordinate (z) will be positive for the one side and negative for the other

Or unrotate the A->point vector by (A->B).GetRotator() and then compare Y values

That's a Vector-Vector node with the second vector split. You can right-click input/output pins for structs and certain data types, like vectors, and use Split Struct Pin to split it into its parts. You can recombine after splitting too

Hey guys not really sure where I should be posting this but I'm running into an issue getting my box collider to work properly on my character. I've set up a box collider so that it would block off my character from entering a specific area, but I realized that it only works when the box collider is located on the ground. If I raise my box collider slightly above the ground my character can go through it, whereas on the ground my character can't. Does anyone know why this may be happening?

Here's a fun one: How would you lerp two curve assets that set a value on array elements?
Use case: I have an array of curves which get randomly selected. They are meant to add height variation to vertices in a procedural mesh in a certain section. Problem is, when a curve ends (on vertex section threshold) & the next one begins, the change in height may be abrupt. How would I lerp the end section of the previous curve with the start section of the following?

Hi ! I have an issue with my collision ... as if they are broken

created a new object Projectile, got to spawn a projectile also but it never generates overlaps or hits ...
both static mesh and capsule are set to profile Projectile.
Both have generate overlaps and hits.
My EnemyPawn has a EnemyPawn Profile with blocking (I tried overlap, doesn't do anything more)

Projectile Actor:

The spawn actor node:

the only time I have a collision update is with the main pawn actually ...

what's wrong with my approach ?

That's the catching overlap on the projectile capsule:

[trim matrix]

Does the static mesh you are trying to use even have collision? Open the mesh asset to check directly.

That sounds like an issues with the projects code. Sadly nobody else but you has seen even a single line of code in your project. Please provide as detailed of an explanation as you can. Also provide screenshots including the code you believe to be problematic.

[trim matrix]

Have you checked that there is not something in front of the ItemButton widget?

[tranquil gorge]

sure i can do that

[true valve]

If I play an in-place animation that changes the player's location by the end of the animation. How can I use MoveComponent to keep the player at the end animation location?

[rough iris]

The [Overlay], [ItemNameText] and [ItemStackText] are set to Not Hit-Testable (Self Only)

[upper summit]

@high ocean You could create a smooth curve between the end of the first curve and the start of the second curve with some lerping similarly to how you've drawn your picture. With a single interpolating value you can lerp between points 1 and 2, between 2 and 3, and between 3 and 4. Then you lerp the results of those three lerps together in the same fashion, and finally you lerp those two to get the final output value. You'll create a cubic bezier from the first point to the fourth point, and the 2nd and 3rd points will act as control points giving additional shape to your bezier.

This suggestion has been brought to you by my recent cubic bezier addiction.

Deciding how far inset into the curve you place the 1st and 4th points is probably just something you can tweak to find results you like.

[trim matrix]

This is an item stack in your inventory widget. Can you click on other parts of the inventory widget? does that work?

[high ocean]

@upper summitThanks for your suggestion, i'll look into it 🙂

[astral epoch]

Floating Pawn Movement doesn't follow navmesh right?

[rough iris]

clicking everywhere works, and the event is fired, it's just the IsHovered returning false

[tranquil gorge]

I actually ended up solving my own problem so thankyou very much for replying. To share, the solution was to make sure both in the blueprint and in the playerstart for both characters that 'auto posses' player number was set to disabled.

[trim matrix]

Nice

[rough iris]

also if I check Is Hovered on target = self it also doesn't fire

it's weird because the button "appears" clicked, like it changes color accordingly

[trim matrix]

I see, not sure then.

[rough iris]

no worries, thank you for your help still 🙂

[cobalt gulch]

How can I fix the camera clipping/culling objects which are very close?

[green briar]

If you dont want it to clip check the camera options, its an option to Do Collision Test

[cobalt gulch]

which group is it located in i cant find it

[green briar]

Camera Collision

[green briar]

Actually its in the springarm

[elfin vigil]

I have this block of code in a binding to populate a text block that appears above an actors head. I'm feeding the values in through a blueprint interface, but it's giving me back 0 instead of the values I set in the actor's class

I think the problem is the get player controller, but I don't know what to put in it's place.

I'm feeding in the default values from a parent actor, then making a child of that actor to customize the values per child

I set this actor to have a cooker rank of 8

[green briar]

You are trying to have the players cooker rank appear over their head?

[elfin vigil]

yes

like this

The far left zero shows a 0 instead of an 8

[green briar]

Where are you setting cooker rank?

[elfin vigil]

as a variable in the actor

[green briar]

Then it looks like, to me, based off your pictures, that the widget isn't receiving your BPI values.

[elfin vigil]

I'm doing everything in a parent, then changing values on a child

[green briar]

Are you casting to the widget or are you making sure to go through your actors widget instead?

[green briar]

Why dont you PM me, I can help you better there

[cosmic kelp]

I would like to set brightness for my game in an Options Menu using a slider and found this solution using a google search. When I tried this, nothing happened on my menu widget. I'm not quite sure I'm using this Post Processing Volume setting correctly. Can anyone think of what might be going wrong? Could I possibly need to set up my own GameMode instead of the default one to see this working?

[lucid lynx]

I've got an actor BP in my level with a public variable referencing another actor also in the level. Something happens with these actors when my player spawns into the level. When running the game in the editor while the level is loaded, everything works. If I start the game in another level then load into the level with the actors, the public variable referencing the other actor seems to be void.

[runic parrot]

Hi! is there any way to update a datatable from the editor with blueprints? (not at runtime, just in edito mode)

[lucid lynx]

Any way to solve this? It's like the referenced actor isn't created yet when the script tries to do something.

[runic parrot]

If the actors are destroyed, the references are lost

[trim matrix]

There is not.

[lucid lynx]

There shouldn't be any destruction going on as far as I know. The actors are in the level file itself.

[trim matrix]

is this "script" the construction script?

[lucid lynx]

No. It's a BP that moves some actors around when the player BP's BeginPlay activates it.

It works when I start the game with the level loaded, but it doesn't when starting an another level then loading into it.

[trim matrix]

how is the reference set? it is an instance editable variable that you directly set in the level editor details panel?

[lucid lynx]

Correct.

[trim matrix]

I see no reason as to why that is happening then.

[lucid lynx]

I know, right? lol

[trim matrix]

What BP has a reference to what BP?

[trim matrix]

since sounds like the player BP has this reference???? Doesnt make sense to me

[lucid lynx]

I have an actor BP in the level that acts as a "cutscene director." It has references to other actors in the level that it moves around and does things with. When the player BP loads it tells the game to begin any director BPs that are set to activate on map load. So player loads into map -> tells any cutscene actor that's set to fire on map load to go -> cutscene actor moves around some other actors like puppets.

[trim matrix]

Ok good. Have you tried directly checking the value of that reference in game? You can use the F8 key to unposses your character and fly around. You can then click on the world outliner and find the cutscene director. You will be able to directly look at the value of any instance editable variables then.

[lucid lynx]

Okay, let me try that.

[trim matrix]

I would imagine the reference is correct and there is just some issue with the game code.

[trim matrix]

After you click on the Cutscene director in the world outliner, check the details panel. The variable will show up somewhere in there.

[lucid lynx]

Oh wow, I'm super dumb. One of the references is literally null in the details panel. I think I changed it a while ago and forgot to put it back in. 🤣

Thanks for the help, I completely forgot about the F8 feature.

[trim matrix]

Well there you go then.

Make sure that value is also NULL on the level though.

There could be a peice of code that is for some reason, setting it to NULL

[lucid lynx]

Looks like everything is good in the standalone build too.

[drowsy crater]

Evening gents

I'm using a blueprint that triggers a ragdoll effect when activated. However the camera gets reattached from the capsule to the mesh, even after reseting.

Someone suggested that after adding the mesh to the capsule, I should also add the camera to the capsule in the reset part, though I'm struggling to figure out how exactly to integrate that into my blueprint, since I've only recently started using UE5, and found the blueprint on blueprintue.com.

If anyone is able to modify the blueprint to solve this issue, or give additional suggestions/ideas, I'd be highly grateful.
https://blueprintue.com/blueprint/ptpb1p7w/

Cheers.

[cobalt gulch]

How can I edit a keyframe on a timeline with blueprints?

[thin panther]

you cant

not as far as i am aware

[cobalt gulch]

Aw

[runic parrot]

Does anyone remember if the "For each loop" reference is a ref or a copy?

[marsh seal]

I think it depends on the the type of variable

some can only give you one or the other

[runic parrot]

it's a copy

[marsh seal]

oh wait I'm thinking of Gets on Arrays

nice!

[tawdry surge]

Everything with a round pin is passing a copy. Diamond pins are passing by reference

[opaque acorn]

Can we control variables of animation blueprint via ui or a general blueprint??

[icy dragon]

Yes, either the same way you pass variables from actor BP to anim BP, or setting it directly from anim instance reference variable.

[golden frigate]

Is there a general way to go about dual hand animation montages?

I hooked up one as I’ve done in the past with blend per bone and did 1 slot for left and another for right but if I play a montage on the left the montage from the right goes away

They don’t play simultaneously

[runic parrot]

Hi! does anyone know if there's a way to have multiple tags on the same actor?
I can only add one : (

oh you need a gameplay tag container for that

[torpid mulch]

Is there anything I should know about changing character height in-game? I mean the capsule collision, can I do it without worries?

[runic parrot]

I think there's a linetrace from the Feets pointing to the floor so check if you are "grounded" or "flying".

maybe if you stretch it too much, that linetrace will become short in proportion and look wonky, can't think of anything else.

[torpid mulch]

I'll give it a try, to see if something happens haha

[torpid mulch]

Guys, If I have a function that is called only on two parts of my blueprint and will never be called outside of it, should I make it a macro? I mean, as it is only called on two parts of the blueprint, there will be no much repetition, but I like to make it something separated (like a function or a macro) just for organization sake.

[desert juniper]

If you want to organize it, just give the function a category

[rotund marlin]

ugh.. why does my character turns its movement forward location based on mouse when https://gyazo.com/45f641aa89b2dbbff0dc35ab7e43d097 is set in pawn..

[torpid mulch]

Yeah, but I mean, as from what I have read, the difference between Macros and Functions is that on compilation Macros are copied into the code where they are placed, where functions are read uniquely and separately, and for example Macros cannot be called from other blueprints while functions can, so my question kinda goes on performance as well, what fits the best etc.

[desert juniper]

Performance isn't a consideration here

[torpid mulch]

Please correct me if I'm wrong on something

[desert juniper]

as for not wanting access on other blueprints, you can just set the functions to private

[torpid mulch]

So what's the best use for Macros? Like, where should we use them?

[desert juniper]

you're free to use them as you'd like

but most people just use functions once they get used to it

[torpid mulch]

Yeah I was doing that, was using macros for more simple things such as shortcuts for math etc

[desert juniper]

you can keep doing that if you'd like. nothing wrong with it

[torpid mulch]

I'll keep on doing it then xD Thank you so much for your attention :P

[desert juniper]

On a side note, if you ever start using any typed programming language like C++, macros don't function the same, and they aren't used for creating any game logic. They're more for compiler instructions.
I've seen most people who come from a typed language tend not to use macros in blueprints.
Only functions are used

[torpid mulch]

I used to code on Unity (c#), but on Unity there's nothing like that, so I was 100% lost about it lol

[desert juniper]

yeah. seems kind of out of place and dated, but 🤷‍♂️ they work if you need them

[torpid mulch]

Maybe they leaved it there on UE5 for compatibility sake, to me it automatically felt like "do quick shortcuts here" because of MMORPG macros having that usage

But yeah I'll keep using it for shortcuts, things without execution etc. Using functions feels more natural to me as I coded on c# before

[surreal peak]

They also allow for some stuff that functions can't

Like wildcard or multiple exec pins

A normal function would need CPP for this, so macros can be powerful

E.g. the "for loops"

[desert juniper]

oh that sounds like a good use of them

[surreal peak]

I honestly never use macros despite maybe an inverse loop or so but even that exists natively by now

[silk cosmos]

That just states that at all time your characters yaw will face the controls yaw. From what it sounds, you mean while moving? Check your add movement input; the movement direction is probably your control rotations forward vector.

[surreal peak]

@rotund marlin the CMC has a boolean for orient rotation to movement or something along the lines

[silk cosmos]

Yeah I believe they're referencing character facing the camera

[torpid mulch]

Tried it right now and it can be indeed very useful

[runic parrot]

This keeps popping on the log every 1 second, even while on editor.

does anyone know what it's? i tried to look for the code, but nothing

(This is not a mp project)

[surreal peak]

This could be some other part of the engine trying to talk to something

Unrelated to the game code

[nimble talon]

is there something like branch but for text variable?

[sly forge]

My blueprint no longer has parent class and i cannot open it to reparent after i renamed my c++ class, is there a way to fix it?

Found this on the internet [/Script/Engine.Engine] +ActiveGameNameRedirects=(OldGameName="ODLCLASSNAME",NewGameName="/Script/NEWCLASSNAME") but not sure what to put in old and new gamename

[teal dove]

Hey guys, does anyone know the blueprint math to create points evenly distributed on the surface of a sphere?
I know of the fibonnaci sphere method, but I have a hard time implementing it into blueprints.

[rotund marlin]

Hm.. Would flipbook question fall under here or animation?

[trim matrix]

If it’s related to blueprint code

[rotund marlin]

i mean its in blueprints, but it contains animation of 2d? :p

[trim matrix]

Just ask

[rotund marlin]

i think i figured it out >.< whelp

[golden pagoda]

Hi friends, I am using ue5 and Build the IOS file in Distribution but still the Print String Are showing, anyone know how to fix this ?

[dawn gazelle]

Closest you can kind of do is Switch on String, but that's typically not the best way to go about something like that. It'd be better if you could use an Enumerator with a switch instead just so there's no spelling mistakes, and processing wise, switching a number is faster than comparing strings.

[rotund marlin]

hmm.. How do i prevent myself from sliding off.. a 2d world? like the tilemap if character collide with other they seem to slide off lol which looks very ironic but not good!

[wise tide]

is there no blueprint node for checking if a blueprint is a child of "x blueprint class"

[icy dragon]

Uhh... Cast?

[wise tide]

it will work if I cast to the parent class? Didn't realise that, ty

[icy dragon]

It will work

Also (depending on the situation) you can have an object reference of that parent class, and any children class will valid for it.

Also casting do the valid check (if object reference not points to nothing)

[wise tide]

I see, that is extremely cool.

Is there something for going the other way where I can get all children classes of a parent class?

[icy dragon]

As in getting all in the scene or getting all possible children classes?

[wise tide]

all possible children classes

I have a blueprint base for pickup items, and each item you can pickup is a child of this class. I want to loop through all the children classes in my actor and spawn 1 at random

however I don't want to make a manual list of all the items to loop through as I want it to automatically change when I remove or add a new pick-up

[icy dragon]

[icy dragon]

Pfft lazy.

[wise tide]

What's correct solution for this then?

It is GAS so maybe the solution is within that system. I should probably ask in that channel

[icy dragon]

Array of classes, or data table if it's going to be static post editor

Hey back again with my nvidia reflex question in hopes someone here may have used it. I followed this guide, https://www.youtube.com/watch?v=BihuOz_earw. I talked with nvidia support earlier attempted clean driver install and disabling services for possible conflicts. Still nothing I load my game debug sits at 0 https://i.imgur.com/fUBRlV4.png. My code while simulating not sure if theres supposed to be indication of firing https://i.imgur.com/B1smog0.png. I have a 2080 super and i've used reflex on multiple games just not in unreal projects im creating. This is UE5.

[trim matrix]

[gaunt viper]

Anybody happen to know why the Enhanced Input system in UE5 just wouldn't be accepting any inputs? I've been following the Third Person Character Stack-O-Bot tutorial (this is my second time going through it, albeit this time on a completely new project as opposed to the Stack-O-Bot one) and I've set everything up as the course instructs but when I get into the game and hit play none of my inputs do anything. I've made sure the Mapping Context is set up properly, I've made sure that the characters is being possessed by player 0, and as far as I can tell I've set up every input action and blueprint as intended, and I'm just not getting any results when I press any of the inputs. I'm still fairly new to UE5, so go easy on me

Don't know if these will help any or not but:

Based on the video, the character should be moving, but the game just isn't doing anything with the inputs. I tried adding a some debug text to each input and nothing came of that either

[fallen glade]

How do you know you've possessed the right pawn? also maybe this?

[gaunt viper]

That doesn't seem to work either, no. As for the possessing the right pawn part, I'm not sure, I'm still a really new to all of this, sorry 😦

[fallen glade]

have you setup your game mode?

[gentle urchin]

Array of soft class pointers* 😄

[fallen glade]

Still don't understand what a softclass is. And I tried :/

[gaunt viper]

Yes, it's all set up as the course told me to

[fallen glade]

mmm let me have a look at one of my projects

[gentle urchin]

Rumor has it that its some string to the class on disc, which you can then load when needed

[fallen glade]

I don't get it haha

What's the difference? sounds the same

[gaunt viper]

Gotcha. I've been looking at the Stack-O-Bot one while trying to solve this, and I can't seem to find anything wrong with my setup, myself. The only real differences between the two that i can see right now are the names of the mappings/input actions

[gentle urchin]

It doesnt load the class itself untill you explicitly load it, so its super lightweight

[fallen glade]

oh so you don't load loads of nested classes?

[gentle urchin]

Like soft reference pointers dont directly point to something, it doesnt tie them together(e.g. both must be loaded for it to work)

[gentle urchin]

You only load it when you need it

[fallen glade]

I see, maybe a bit too advance for my thinking. Thanks for the explanation!

[gentle urchin]

It goes down the drain once you cast tho

[fallen glade]

If you print this do you get what you think you should?

[gaunt viper]

Doesn't seem to be showing anything, no, but I also might have it set up wrong, lol

(Sorry again, like I said before still very new to Unreal)

[gaunt viper]

Okay I got it to print, it does print the character Blueprint

[fallen glade]

Why do your inputs look like this? mine are different just a sec

is that a UE5 thing?

[gaunt viper]

I'm not sure, it might be

I'm going off of this course/tutorial series: https://dev.epicgames.com/community/learning/courses/kry/build-a-third-person-character-from-scratch/lo4/setting-up-inputs-and-building-control-systems

I've already done it once using the example project, now going through it again as a refresher in an empty project, with my own model/animations

[fallen glade]

oh, I've never used an imput mapping file whatever it does sorry

[gaunt viper]

You're good, thanks anyway

[wanton galleon]

Hey, I'am missing something ? I try to spawn an empty actor and attach a capsule component to it for a collision test, but whatever my transform is, the actor is always spawned at 0,0,0, it is normal ?

[trim matrix]

what should i use to get the direction of my pawn in Anim blueprint

Get velocity + Vector length = speed

Get actor forward vector + ? = direction forward/backwards

[untold fossil]

For some reason I can't see my exponential height fog in the editor, but when I play it works fine. I also checked to make sure show fog is enabled in the show menu for the viewports. The hell is going on?

I even tried a completely new scene with just a sky sphere, fog, a plane mesh and directional light

When I hit play fog works perfectly fine, but in editor I can't see it no matter what

Anyone have any idea what kind of annoying trick the editor pulled on me this time?

Gotta love random stuff just suddenly not working anymore

[tawdry surge]

@trim matrix easiest way would be to save your axis value to a variable and if it's >0 its forward <0 backwards

[blazing kiln]

Try using node get direction from movement comp

The other way is using math with dot product, but get direction should work fine

[bronze hill]

Is there way to find out what is binding to Event Dispatcher?

[fair sun]

Event destroyed gets called when an actor has been explicitly destoyed, is there a function/event that works when an actor is destroyed by travel/streaming?

[bronze hill]

other things just press find referrence but it's not, i can't find

[fair sun]

I have BindEventTo when I press find reference, maybe nothing is bound?

[icy dragon]

What are you trying to do?

[fair sun]

I want to call stop music when my music actor gets streamed out

[bronze hill]

ah ha, that's could be? thanks i will try another

[wanton galleon]

#blueprint message Hey nobody ? :/

[icy dragon]

Stop the music before you do level travel?

[wispy star]

Greetings!
Maybe anyone knows if there is some way to connect multiple nodes/pins at once? Like here:

[lapis inlet]

Alright need help, I want this to run continuously but I want to check if the actors in the list have already been added (so that they are skipped), any thoughts on how to achieve this?

[icy dragon]

I felt like I'm getting myself into a honeypot repository 🙃

[wispy star]

it's just docs repo, source only provided via marketplace

[icy dragon]

Not the first time I stumbled into such repo.

Felt like they serve as honeypot repo, tricking search engines in the process for those who are looking for free (open source) versions of the tools (or alternatives that do pretty much same functionalities)

I say that's pretty cunning even if it's unintentional to that specific bait goal. Even though there are other ways to store docs.

Perhaps I should do that next time I'm selling plugins or other stuff

[remote meteor]

endplay

[wispy star]

i guess main reason for that is MP is SOOO annoying to update so people just don't bother

[remote meteor]

also you can point the owner of the sound to something within the streamed level

and it should destroy along when level is being unstreamed

[icy dragon]

The likes of Google Docs or Read The Docs do exists, but I digress.

Whoever did that first is a genius.

[lapis inlet]

Urggggg calling arrays is so difficult

[icy dragon]

Make a doc repo of a paid plugin, making sure none of the repo nor the description says it's a documentation, then somewhere a hidden message that says "hahaha you're getting jebaited now buy my product lmao"

Delightfully devilish marketing 😈

[lapis inlet]

Guys I would really appreciate the help

[remote meteor]

use AddUnique() instead

[lapis inlet]

Oh, that's a thing?

Holy shit

I think you just

solved a shitton of problems

[wispy star]

@supple dome well, it seems it doesnt work on anything except BP and Materials...i've tried Niagara, Audio, and custom logic nodes -_-

[lapis inlet]

@remote meteor Weeks of troubleshooting and nowhere close to completing, and turns out all I had to do was use AddUnique() instead of Add

https://tenor.com/view/praise-allah-gif-24350702

[sonic moss]

I might be able to help with this - you were following the course but on your own project, not the Stack O bot one, yes?
And your character is just straight up not moving at all?

[remote meteor]

It will return index -1 if it already exists

Else it returns the new index

[lapis inlet]

So I want to remove actors that the player destroys from the array

How do I set about in doing this?

[gentle urchin]

Use 'find' before add

[lapis inlet]

Well thing is

[remote meteor]

Bind on destroy

[lapis inlet]

The array is in a gamemode

[gentle urchin]

You can bind to an actors destroyed event

[remote meteor]

Remove from array

[lapis inlet]

And the player has a seperate blueprint

[gentle urchin]

Also

Its better having the bps register to the gm

[lapis inlet]

I do this atm

[gentle urchin]

Than running get all actors continously

[remote meteor]

This

[lapis inlet]

Care to explain like I'm 5? My blueprint knowledge is severely limited

[gentle urchin]

Making dinner so short on words

[remote meteor]

Enemies when they are spawned will add themselves to the gm array

Bind on destroy (will return you which actor is being destroyed)

Remove from array

[gentle urchin]

Like registering a car

[lapis inlet]

So is binding a process that needs to be run? Before removing?

[gentle urchin]

Imagine if they each day ran out chevking every damn car if it was registered

And if its not, then register it

[remote meteor]

Bind is an event listener

[gentle urchin]

Compared to every car owner being responsible for reporting in their car, and getting it registered

[remote meteor]

It waits for something to happen then, does it.

You call that event dispatcher

[lapis inlet]

Aaaaaaaah

So don't run continuously

Only run when an event triggers

Eases performance

I can understand the principles for that, just didn't understand the terminology

[remote meteor]

Do the binding when you add it yo the array

So they 'come in a package'

[gentle urchin]

I guess this could be a scenario for an interface?

The registration part

[remote meteor]

Yeah

[gentle urchin]

Generic actor input. Afterall, GM doesnt really care what type of actor it is

And can still register to its destruction event

[remote meteor]

Something like 'Report Gameplay Event'

And based on different game mode

They can be handled differently

[golden frigate]

Is there a way to play multiple anim montages at once for different blend per@bone bones? Mine just resets the others when it plays

[gentle urchin]

You can play it to different slots ?

I think..

[lapis inlet]

Oddly enough, the game runs smoothly even with the dogshit blueprints I have

[remote meteor]

Usually it wont tank to slideshow instantly

[lapis inlet]

And honestly? Can't be bothered with troubleshooting, considering the project needs to be submitted tomorrow

[remote meteor]

It takes a combination of dogshit to make it happen

[golden frigate]

I tried that didn’t work but maybe I setup the slot system wrong

[remote meteor]

:)

[lapis inlet]

Previously it went to slideshow within 5 seconds

Now I don't see slideshow happen for, well, haven't checked

A couple of minutes of decent smoothness should be fine

It's not like my teachers are actually going to play the game anyways, they just want a video

[remote meteor]

😅 inb4 lecturer had fun and decide to play it at home

[lapis inlet]

They never specified to send the game files

Just videos

[remote meteor]

Lol

[lapis inlet]

But seriously, thank you so so so much!

I might actually pass this course

Anyways, I need a system of movement for the player

My original idea is to project a raycast from the mouse on a holding mouse click to produce "thrust" in a direction

Imagine a spaceship, and where the mouse clicks the craft would travel using a set addforce modifier

Accelerating, but not travelling immediatelly

Oh shit the slideshow suddenly begins to appear at 10 seconds, probably fucked up

[remote meteor]

or you can just modify the movement component parameter on
maxacceleration
maxvelocity

[gentle urchin]

Dont be so logical

Make it as complex as possible

Im doing custom physics engines for my 2d paper plane game

Fun times

[balmy vessel]

Hey guys, I have a part of a project where we have meta humans and we want to swap out their clothes.

A way to do this I thought was to have an array of actors which represent each clothing state (its not as easy as changing 1 thing for the outfit with metahumans so changing just the clothes may be harder/cause a bigger load) the issue im having is the player controller I'm putting this behaviour on wont let me edit the default values of an array of actors so I can add the blueprints from the content browser in.

Any ideas why or how to fix this

[silk sandal]

Hello I want to make a fortune wheel blueprint so I was wondering if its easy or not

Already have

but im more for the actually application of movement itself

Calculating the direction is proving difficult

have you by any chance

had a look into

[hasty dune]

Hello everyone ! I ask for your help because I have trouble finding "simple" explanations of my problem on the Internet.

I am currently creating a cannon projectile, and I would like it to be able to fire in an arc (like a mortar). I managed to do it with the mortar with the function: "Suggest projectile Velocity Custom Arc" which varies the velocity of the projectile. But here it's different, I have two points that can change position (initial spawn projectile and the target location) and the initial forward speed of the shell, so I would like to calculate a trajectory that hit the target and get the initial angle.
I don't know how to do it, thanks to those who can help me !

[lapis inlet]

BTW what is square root in UE4? sqrt with 2.0?

[icy dragon]

Sqrt node?

[lapis inlet]

Well, yes

but what value?

2.0?

3.0?

[bronze hill]

should i use collapsed Graphs over functions for cosmetic purpose? or i can make function as many as i want?

i feel like function is superb but also feel like there is downside

[remote meteor]

either is fine, as you suit

there is only very few scenario where one can do something other cannot do

[bronze hill]

thank you, now I'm relieved

[remote meteor]

well if you must need something

dont clutter your event graph

editor gets laggy

[untold fossil]

Does anyone know how to make a camera system like this? Click and drag https://www.youtube.com/watch?v=LjRY86YT8UM

[lapis inlet]

@remote meteor ok just reaslied, how do I check and update actors in the array?

Like if one actor got more health from a pickup, and needed its health to be updated from the array

But not added, just changed

[bronze hill]

ok i got it. thanks!

[remote meteor]

you dont have to if they are Array of Actor reference

[lapis inlet]

Well then I think someone is wrong

cus the changes are not being applied

[icy dragon]

Whatever value you want to put in and do sqrt operation, I guess?

It's not like square root is also  ∛ or anything

[lapis inlet]

Figured it out, but cheers regardless!

Also, screw it, imma redo the entire casting part of my blueprint

This is what I currently have

The delay at the end forms a pseudo loop by just rechecking it every second

But of course, its uneeded

Any thoughts on how to improve?

[icy dragon]

Change the evil delay loop hack with looping timers

[lapis inlet]

How do you make a looping timer?

[icy dragon]

Set Timer By Event (or Set Timer By Function Name)

[lapis inlet]

Oh, so if I were to have an actor collide with another, I can set an event to play and then call for it to happen inside the gamemode blueprint?

Would this work?

[random plaza]

is there any way to make an onject visable to only one camera?

i have 3d menu parts and i dont want to have them constantly in the world

[cyan bone]

I have one line A-B and a group of 10 random lines. I need to find which one of the random lines is the most straight in comparison to my line A-B. Do i do this with cross product?
I tried it and failed. What value should i use to know which line is the most straight in relation to the A-B?

[remote meteor]

dot their direction vector

whichever closest to 0

[cyan bone]

So thats the same a using cross product Z, right? So all i have to check is which one is closer to 0

[remote meteor]

yas

[cyan bone]

How do i do that? Using a Min?

Min with Abs?

[remote meteor]

i suppose you need to test 1 by 1 in an array

and save the smallest value's index

[cyan bone]

yup thats what i did. And using abs with <. It worked so far :). my soldiers are going straight ahead 🙂

[rugged wigeon]

@lapis inlet I think you are confused on math terminology. A square root is something to the power of (1/2). The inverse of it being squared, which is the power of 2.

x^(1/3) would be referred to as a cube root, for example.

[lime moat]

anyone know if its possible to edit lock position/rotation constraints in BP?

[lapis inlet]

Yea I figured it out

I understand what square cubed and square root is, just not what it was represented as in UE4

Which is the Sqrt call

But cheers!

[random plaza]

i have a recipe in the form of an array of strings, how would i check if one array contains another?

[lapis inlet]

Moving on, I need help with how custom events work - how do I call a custom event from one blueprint to another?

[rugged wigeon]

You need to drag out from a reference to the other blueprint

[jolly surge]

so i've made a function like that, when i call the function, it doesn't actually give each item, only the first one.
I guess it's something with the way it execute, any way to make it work?

[lapis inlet]

So a "casttogamemode"?

[jolly surge]

Here i used it, but it doesn't actually loop and output, only once

[rugged wigeon]

@lapis inlet it depends on context. Some way or another, you have a reference X, which you know is an instance of blueprint Y, and you can drag out the blue pin from it say X is calling some event

[lapis inlet]

Oh it, wasn't that hard

[gentle urchin]

Cast to MyCustomGameMode, sure

As input you can use GetGameMode

[lapis inlet]

Alright so now that the casting is done, I need to reference both the player actor and the colliding actor inside the gamemode

[random plaza]

i really do need to know a solution to this

[rugged wigeon]

That seems very suspect though. When something begins overlapping, the game mode calls an event called collision? It seems likely that the object doing the collision should be calling an event.

[gentle urchin]

But in general you can access an objects methods/functions/custom events / public variables by having a reference to it

[rugged wigeon]

@random plaza you'll basically just need to check if every element of A is contained by B. If order matters too, that's another can of worms.

[lapis inlet]

nods

[remote meteor]

for each, contains, if not return false, after the loop completed return true

[rugged wigeon]

blueprints aren't a particular pleasant place to do a lot of operations on arrays

[lapis inlet]

So I need to call the parent blueprint (the actor) inside the gamemode now, how do I do that?

[random plaza]

only issue is this is an array of strings, and some of them could have duplicates

[gentle urchin]

Recipe usually is a small array in this context tho

[remote meteor]

or you can look into set 😉

[gentle urchin]

So bp performes just fine

[remote meteor]

https://docs.unrealengine.com/4.26/en-US/ProgrammingAndScripting/Blueprints/UserGuide/Sets/

[gentle urchin]

Set cant have duplicates can it

[rugged wigeon]

@lapis inlet you could add a reference to the actor as an input to the event

[lapis inlet]

How does one go about and do that?

[rugged wigeon]

@random plaza I think you're confusing people with your requirements. You mention recipies.

Does order matter? Does the number of appearances of each ingredient matter?

e.g. if A needs 3 rocks and B has 1 rock, 1 sand
does B "contain" A?

@lapis inlet

[random plaza]

my only issue is it would require 3 iron, and there's just one iron in the stockpile it would say "well, theres iron in there"

[lapis inlet]

Aaaaaaah

Cheers!

[rugged wigeon]

@random plaza so it sounds like you're saying you're comparing recipes and a stockpile.

If recipe needs 3 iron and stockpile has 1 iron, should this function return true or false

[random plaza]

it should return false

also, items dont stack yet

[gentle urchin]

Id have a tMap 😁

With quantity

Not stack yet sounds like you want it to stack

[random plaza]

i'm making a colony simulator with automated jobs for npcs

[lapis inlet]

Alright so, kind of confused here, how do I call for the sphere component from my Player Actor, inside the gamemode blueprint, using a reference through an event?

[rugged wigeon]

Honestly you should just stop using string arrays and do it properly.

Make a struct with one entry per resource.

[gentle urchin]

This sounds very wardbacks

[lapis inlet]

Or maybe

Call the component in the player bp

And take it through the event

That could work

[balmy vessel]

If i have an actor that has lots of different clothing options which are their own individual blueprints (each blueprint works as a seperate actor, they all have the body + clothes) is it a fine approach to spawn an actor in the same transform and then destroy the old actor? or should I look into just changing the cloth static meshes/materials and changing those, will it affect performance and be something i should worry about?

[gentle urchin]

TMap with GameplayTag and quantity(byte/int)

[rugged wigeon]

@random plaza
Something like this

Then your function for "does stockpile have everything the resource needs" is just checking if all the values of stockpile are >= the values of the recipe

[balmy vessel]

atm i'm juist spawning and destroying actors as i go through the array of possible blueprints

[random plaza]

only issue is the system i have is using strings as shorthand for the actual item structs, i have a struct that has over 20 entries on it and it gets the items from its name

i can send you a pic of the item struct if you want

[gentle urchin]

The last option keeps it more modular

So you dont need a char for every possible combination of clothing

[random plaza]

using this system i can bring the items from any inventory on the map, and do whatever with it

[balmy vessel]

thats what i was thinking, my concern is how hard it could be to setup all the different meshes/materials

we're working with metahumans so its a bit more of a pain

[gentle urchin]

Soft object refs

[gentle urchin]

Still its just a one time job

But if the sets are few then... idk 😄

Your job, your choise :p

[balmy vessel]

yeah, i'll talk to my line manager about it and see if its worth the time investment

[random plaza]

can you elaborate?

[balmy vessel]

but is spawning and destorying taxing to the system? id assume no as long as its not every frame haha

[hollow gorge]

hey, do you mean chorded actions like Ctrl + L, where one key is only a modifier or are you talking about simultaneous button presses of buttons that have other actions bound to them usually? like LB, RB and LB+RB triggering abilities?

[gentle urchin]

Swap the hard refs with soft refs to not load things that dont need to be loaded

[remote meteor]

in DataTable, it is recommended to use Soft Reference for any Asset Referencing

else

everything will be easily referenced and rip RAM usage

[gentle urchin]

Nah not very taxing. Use soft class refs 😄

[gentle urchin]

Yes when the asset is only needed on request

[random plaza]

i really am confused, im not using data tables for this. i'm storing the objects in arrays and saving them automatically to the save file.

[gentle urchin]

Ignore my comment then^^

[random plaza]

thats completely fine

[rugged wigeon]

Seems... unlikely that you need to store a lot of these variables. I would expect you could just store a reference to what class the object was, where it was located, and any unique properties of the item.

[gentle urchin]

Exactly

[balmy vessel]

wym soft class refs?

[random plaza]

i didnt know about data tables when i made this system, and if i gutted the whole thing it would set back my progress significantly

[rugged wigeon]

welcome to game dev lol

[random plaza]

yep

[final lava]

thx, I did already found that it chorded action 😅

[rugged wigeon]

But I guess going back to your original issue, using maps or structs to count how many of a given resource you have isn't incompatible with using strings as lookups in a data tale or what not.

And that's what you should be doing

[gentle urchin]

Hence the GameplayTag notion

Avoids typos in strings

[hollow gorge]

okay chorded action is the simple use case. did you also try with keys that are also bound to other actions? like LB being one action, RB another and LB + RB a third?

[rugged wigeon]

Yeah squize's suggestion is probably better here. Look into gameplay tags. They're basically pre-registered strings within a project.

[gentle urchin]

Requires a rewrite of a system, but it shouldn't be insane amount of work

[random plaza]

are data tables dynamic? can you add to them using blueprints?

[gentle urchin]

No

Static

[random plaza]

good to know

[gentle urchin]

Like item info is

[random plaza]

so arrays for save files, data tables for item classes

[final lava]

I am fine now. I just didn't check all input action options. So basically I just now discovered chorded 😅

[gentle urchin]

Datatable for static sets of data

[hollow gorge]

ok if you find yourself doing simultaneous presses of already bound keys and find a solution that works... ping me 😉 because I'm having troubles with that

[wraith crane]

can you somehow encode and decode a string in blueprint?

[restive tendon]

Hey so I'm extremely new to UE and idk why but this simple function is taking me forever to figure out lol. I have an actor that when it's entered a widget will pop up that says "Press E To Scan" and the widget dissapears when exited. I want to make it so the actor is destroyed when you press E (which I have as an input called Interact). But my InputAction node isn't working. I can't even get it to print a string when I'm in the actors collision box. How can I fix this?

[gentle urchin]

Enable input

After add to viewport

[wraith crane]

i want to do this bcs i try to add multiplayer to my game and i want do encode host ip

so that when switching on the ip, only such a lobby password would be used

[restive tendon]

Like this? If so the string still doesn't pop up

[gentle urchin]

Get player controller

For the input on the enable input node

[restive tendon]

My God I knew it was gonna be something so simple lol thanks for the help I really appreciate it

[rigid mantle]

Very new to UE5, If I want something to persist across levels, are there global variables or something similar? or do I pass the variables to each level?

(for example time of day)

[gentle urchin]

GameInstance

Persists

[rigid mantle]

Ahh perfect, Thank you

Will go research 🙂

[gentle urchin]

Alternatively save and load via saveslot

[rigid mantle]

That is not a bad idea either, at least that way it would be a save point at every map load and less to less potential data loss

Will do some research and thinking, thanks!

[final lava]

do you mean by this? I do not use Chored Action for now. But for quick test I did add 2nd key to InputMappingContext to Jump Action as on pic example and it works. Player have to press space+N to jump. PS: this is just my working example. You can also add Triggers inside InputAction instead in InputMappingContext . But all keys should be inside InputMappingContext .

[harsh coral]

Quick question:
Lets say I have copied a blueprint asset a few times in the level and changed a ton of settings on ONE copy of it....
Is there a way to copy/paste ALL settings from one copy to another one?
Right now I can only seem to copy/paste one setting at a time, which can become quite tedious.

[gentle urchin]

If it was a struct

I believe you could copy it in its entirety

Id just make a helper bp

With editor event

Copying between source and target(s)

[harsh coral]

Yeah, I´m a little less advanced, it was a bought market place asset...:)
Of course I can copy the whole blueprint, but I already placed it a bunch of times and animated it etc, so I really just wanna copy the settings.

[gentle urchin]

Exactly

Helper bp

Blutility, if you like

Takes a few min to setup

You know how to create new actors, custom events, and reference variables?

[harsh coral]

Nope.

I have messed around a bit inside the blueprint, but I haven´t done anything from the ground up.

[gentle urchin]

If i wasnt babysitting id show you

[harsh coral]

haha, yeah, I´m babysitting too, but mine are a bit older I guess..:)

[trim matrix]

Hey does anyone know why my screenresolution doesnt change? im executing it in the start widget that im loading at gamestart

[gentle urchin]

6 months, with a fever 😂

[harsh coral]

Ouch. 8 years, no fever, but twins...:) Get well soon!

[nimble talon]

i know no one asked
but to create this points on lines(idk what are this called) you must double left click

[blissful grail]

They're called reroute points. Can search for it as well.

So if you pull out the execution line and then let go (without connecting to anything), you can just search "reroute" and it gets this.

[nimble talon]

Ok

double clicking is easier

[blissful grail]

It depends on the situation on which one you go with.

[green briar]

Hello, I am having some trouble getting this capsule trace to be how I want it. Can anyone help me out? Not quite sure what to put here to make this work.

[cyan birch]

Is the issue that it's casing from the center of the player, not the front?

[green briar]

Correct. Apparently simply getting my forward vector and increasing it for the Start doesnt work

[cyan birch]

Really? Like you can't use the same math you used to determine the end for the start? That seems...odd.

[green briar]

Okay

I just got it lmao

[lone gull]

hi, I have a question. I am making a multiplayer Game. I have one character and one Ki. I want that every Player have a amount of Ki. Like That when two Player join the Game that both of them have 20 Ki as an army. And then That the Ki fight against. How can I make that both Player get a Ki army? How can I make that 20 ki spawn at one Player and follow one Player and 20 ki spawn at the other Player and follow him? Right now the Ki only work for Singelplayer.

sorry for bad english

In the Ki I have a Character ref but it is not working with the Multiplayer

A ki that follow The player

I allredy program the ki

But the character ref dont work

[gentle urchin]

Ki -> AI?

[lone gull]

Ki = Ai

or?

[gentle urchin]

Kunstig intelligens

[icy pilot]

Are there any tricks i can use to sort those components in this BP ?
Cuz right now the sorting is just a mess

[random plaza]

can you sort an array of strings by size?

[gentle urchin]

Sure

Length of string

[flint shard]

I'm using GetHitResultUnderCursorbyChannel to figure out what part of my terrain/landscape is being pointed at by the user. But the hit sometimes goes below the terrain. I've got Collision Mip Level and Simple Collision Mip Level both set to zero on the Landscape actor. If anybody can help me figure out a way of getting this to not happen, I would be super appreciative. Here's a picture of the problem:

[mystic ether]

Hey i'm trying to get the dominant wind angle (WaterBodyOcean) in a pawn, how can i link this, do i need to create a manager? thanks

[flint shard]

Hey nevermind, I figured out I was being silly and setting the icon location somewhere it shouldn't have been instead of the hit location.

[cyan bone]

Im trying to add text component in specific places in world location. But it seems there is only the option to set it as relative?
Is there a way to create it in world location?

[gentle urchin]

Finally asleep. I got a minute if you still want help

[onyx token]

okay-

could it be that interfaces are a little bit bugged?

sometimes?

[gentle urchin]

unlikely

[onyx token]

so-

i have an overlay notify

[hot ice]

anything wrong with (self -> world location ) - (target -> world location) = relative transform EDIT: or the other way round

[onyx token]

and i got this on my notify end

(and on my notify begin)

For some reason-
The weapon State gets sent
The animation doesn't get sent

but if i put a print in the overlay to print out the animation value - it works

[icy dragon]

DVORAK typer eh

[onyx token]

And whatever i put below that - strings, bools, floats-

they all don't get sent

only the first bool gets sent for some reason

BUT

on my play it does get sent

but only the animation & the bool, nothing i put after

my NPC only sends the bool

even though they all share the exact same code

[icy dragon]

Maybe you mean 地

[dark heron]

Hey - new to unreal here coming from a Unity background. I'm getting my feet wet with blueprinting, specifically behaviour trees. How do I expose a variable on my controller that can be passed all the way through to the behaviour tree? I tried making an Actor variable and toggling Instance Editable, but I'm not seeing it anywhere (or looking in the wrong spot).

Once I have that variable, I assume I pass it to the blackboard which the tree has access to?

[gentle urchin]

curious why you use an interface to the owner of the anim, cant you just cast ?

[remote meteor]

Blackboard yes,

BT can access blackboard values

[onyx token]

because it can either be an NPC duder, or the player, or an animal or whatever else

[gentle urchin]

aight

[onyx token]

I want to make 1 overlay to fit them all, which leads into 1 animBP which fits them all, which leads into 1 ParentClass which fits them all

[gentle urchin]

I guess a cow and a human npc dude share the same animation

[dark heron]

I'm struggling to set that variable somewhere. I'd like to select another actor in the scene.

In Unity, I would make a transform property, then drag the other object to it. Not sure what the equivalent is here

[onyx token]

nope, because they get child animBPs

and there i change up the animation

But the code is the same

[gentle urchin]

ah

ofc

the notify isnt locked to the anim

[onyx token]

ye it's just a notify i can slap on anything

[gentle urchin]

yepp

im just being dumb lol

[onyx token]

if only the interface would work

[remote meteor]

when you enable the BT in your AI Controller, you need to specify which Blackboard to use

after that

you can access the Blackboard variable from within AI Controller

you can set the values from there

[dark heron]

I'm not currently having issues communicating between the controller and the tree

I'm having issues setting the variable in the first place

[cyan bone]

Sorry i didnt understand. I need to create 3d text on specific points in the map. But i only have the world location. If i plug in the world location, then it will be off.

[remote meteor]

setting the variable?

[dark heron]

I would like my controller to be aware of another actor in the scene. I'm not sure what the way to do that is

[remote meteor]

hm may need a long way to do that

first i dont think controller will be manually placed in the level designer

so you cant exactly just item picker with a controller

[barren hill]

Hello guys! I have a graphing question if anyone can help me.

Issue: I have two levels Level 01 = Main Menu and Level 02 = Actual Game Level, I'm attempting to change the FOV using a Widget Slider the problem I'm having is because my game level is different then my settings widget which is located in my empty main menu level it's not actually changing the FOV of the follow camera.

Question: How can I cast or change my BP_ThirdPerson_Character from a different level such as Main Menu Level?

Notes:

• My Widget (Settings) is located in empty level Main Menu 01 {They are in separate levels}
• My BP_ThirdPerson_Character is located in Game Level 02 {They are in separate levels}

[dark heron]

The controller is currently attached to two mannequins in the scene - not sure if that's the correct way to do it

[hot ice]

The add text render component should be attaching that text to an actor no? Hence the relative transform from that actor. If you use self -> world location that will get the world location of what you're attaching to so you can calculate the relative transform to your desired world location

[gentle urchin]

What about grabbing the anim from the weapon when the notify is recieved ? Instead of sending it over the interface

[onyx token]

well the weapon doesn't animate, it's just parented to the socket...

[gentle urchin]

well, whatever animates then i guess ?

wouldnt that work?

[onyx token]

i guess i could use normal skeleton-based notifies to grab it from the animBP

but it annoys me that the interface doesn't work

[gentle urchin]

probably some logical reason for it to not work

unknown to me, ofc

[onyx token]

yea because it does work for the player

[remote meteor]

hm anyway, if you want to do "item picker" style

[onyx token]

i'll look for it... If i can't figure it out because my brain not wrinkly enough, i'll work around it... thanks tho! @gentle urchin

[remote meteor]

first the object has to be in the level designer

[onyx token]

i just wanted to know if anyone knew situations where interfaces were just bugged sometimes, like blueprint structs sometimes are

[dark heron]

it is, so that condition is met

I just have two characters with the same AI controller that I would like to make aware of the other through a variable

[remote meteor]

that axis is an ai controller?

[dark heron]

that's the plane

this is the controller, nested under each player

could be bad practice, I'm new

[remote meteor]

i can understand the confusion 😅

so you see, usually you setup your AI controller like this

in the class default of your pawn

there is an Auto Possess AI, with the class

[dark heron]

I assume SkeletalMeshActor doesn't have access to those fields?

I might need a different type of actor

[remote meteor]

A Controller can Control a Pawn

so it has to be a subclassof Pawn

it can be Character and so on

[dark heron]

That's where I get lost

I know the terms, but I don't know how to place pawns or tell if these things are pawns

I just saw a model and dropped it into the scene

[remote meteor]

when you create blueprints

you can see their class hierachy

for something to have an AI Controller

it has to be atleast a Pawn

[dark heron]

I believe the blueprints are pawns, but I'm not seeing how to properly link the blueprint to the actors now

My AI Controller does derive from pawn

[gentle urchin]

You can also see parent class when hovering it in the content folder

[gentle urchin]

Or up in the right corner as you showed^^

Pawn is good

Pawn is life

For controllers anyways

[remote meteor]

AI Controller is AIController

[dark heron]

Pawn is life. Noted

[onyx token]

holy shit

i'm fucking braindead.

@gentle urchin

[gentle urchin]

Pawn is the intented controllable class in unreal

[onyx token]

i am a literal

[dark heron]

Now how do I go from 2 dumb models in my scene to having them use my AI?

[gentle urchin]

Found the mistake?

[onyx token]

no braincells here.

not one.

[gentle urchin]

LoL

[remote meteor]

are your model still in simple state?

[dark heron]

I just dragged and dropped things in

[gentle urchin]

Time to quit buddy. 😂

[dark heron]

They're SkeletalMeshActors

[remote meteor]

alrighty

so now you need to create a Character subclass

[dark heron]

done
