is it possible to destroy my projectile before this part plays and still have it play that part after the projectile is destroyed?
static charm
yes although not sure if the delay would still function
destroy actor doesn't immediately kill the code. it just calls the actor to be killed and calls the rest of the code.
surreal peak
DestroyActor should always be the last thing you call.
surreal peak
Not sure what happens if whatever you call afterwards checks pending kill on it
static charm
that would make sense because the delay is a few ticks later
but code called in the same tick as destory, should still function
surreal peak
Destroy it after the delay
static charm
what didnt work
static charm
are you using the default projectile from template? that already has a destroy or lifespawn/kill time set
oblique gyro
it does but the projectile just stays there for .5 seconds then disappears
and no
and what i want is the projectile to destroy/disappear and for the mat to change
static charm
Then hide the projectile before delay, then destroy after delay

Do you have any video suggestions for making a slide animation possible?
I have the actual animation
I've parted it into start, loop, and end
but as for putting it all together in the state machine and what not, jeez.. thats tricky
static charm
this one uses a montage
and might require root motion, which may not be what you want
twilit lily
I mean, montage works too xD
odd ember
has anyone had issues with SetTimerByEvent not firing on CreateEvent functions?
twilit lily
I have not tried that
twilit lily
I actually do use force root lock

Small issue
My attack animation uses the default group called upperbody so that it blends with running and attack etc
This guy wants me to add the default group default slot, which makes my attack animation not work after I slide.
and me being a noob, have no idea how to fix that
static charm
i dunno i dont do much animation work
trim matrix
the slot overrides the animation thats playing
trim matrix
if theres no animation playing in that "defaultslot", it will use the previous logic
twilit lily
So it will just use the upperbody then
trim matrix
depends, its must be playing some anim in upperbody
twilit lily
my character feels slow and hard to control when I press the slide button
So its doing something
Any suggestions?
trim matrix
whats is the problem?
twilit lily
So I'm trying to utilize this slide animation
but it calls for the default pose
meanwhile my attack animation needs upperbody
so if I slide
I cant attack anymore

Could someone help me troubleshoot why my interface isn't sending my PrimaryFire input to my PlayerWeapon Actor, which should be firing a projectile on my Fire event?
Both BPs have the interface, and the weapon fires when I do a direct Cast To, but I would prefer to use an interface for a bit more flexibility..
twilit lily
trim matrix
its selected the right group in montage?
twilit lily
twilit lily
Hmm, where do you see that?
trim matrix
click in the slot, at anim graph
twilit lily
Ah, let me try
twilit lily
Sadly not
I think
It's my do once breaking
It was set to reset after the montage completed, the attack montage
I took my do once out and now I can attack at will
trim matrix
on completed maybe isnt called if you call another montage to play before it ends
twilit lily
Crap
twilit lily
But then you could spam the slide

I am implementing a couple global systems, and I'm pretty sure SubSystems are going to be the way to go in the future. In the meantime, does each system being a component on Gamestate seem reasonable?
trim matrix
crypto
use a delay
and gate
instead do once
so ur mechanic insnt dependent of animation times
twilit lily
gate?
trim matrix
or in anim instance you have that node that returns the time for the montage
twilit lily
Gate looks interesting
trim matrix
@faint pasture depends of ur component necessity
usually components that only belongs to server wont be even spawned to client
twilit lily
Surikate how would I use a gate and delay?
twilit lily
Why would I need a sequence?
trim matrix
to easier ur life
instead plug things from kilometers away, you know the sequence will execute the code

@trim matrix I'm pretty sure gamestate exists everywhere
trim matrix
yes, but ur components depends

any component on the CDO of a replicated/pre-placed actor, as well as any replicated component on a replicated/pre-placed actor spawned in runtime exists on all machines

class default object
if you're using BP only think visible on the component panel in the BP

I've got a flashlight (just a simple spot light attached to a spring arm) for my character - is there any way to lower the brightness on things close by and increase it on things further away? For the light to be bright enough to show things at a distance, I have to have the intensity pretty high, but that makes it utterly blinding up close.

@unkempt granite Increasing attenuation should do that, if you haven't set that already

How would I check if a location is on a spline path?

depends what your goal is
there is a node that checks distance from spline
and some other related nodes
that does stuff
related to splines
split ginkgo
I want to make an AI follow a spline path, and then be able to leave it it if needs to then hop back on the path
I found a way to get the closest point on a spline path from the actor
I just want to find a way to check if it is on the path
And I think I could be able to do the rest

yes and if you check distance from path, and the distance is 0 or some other low number
then it's on path

Okay, whats the node for that?
snow halo
Hey all i'm print a float and I just wanna round to the second decimal place.
by default it shows 1.111f for example, but i just want 1.11f or 1.1f. Any easy way in bp?
this is print through a widget text object
snow halo
can i do that with text or do i need to convert to string?
static charm
string has more options
snow halo
ultimately SetText() in widget BP wants text. Lots of conversion nodes hehe
it's already spaghettis soup
static charm
well the only way to do it with maths is multiply and then modulo then divide
so always gonna be bunch of nodes
i think there is a c++ node though
that just lets you specifiy how many places you want to round to or truncate to or something
snow halo
ya, arg i'm stupid for using bp on this widget ui

i dunno, i was told people who willingly do ui in c++ are masochists

I'm making some experiments with a Third Person game, and I want to hide the mesh of the character when the camera is too close to it (for example, when the character is close to a wall and the player rotates the camera). I added a SphereCollider to the part of the camera the will probably collide with the character's CapsuleCollider and set the collision presets to overlap every dynamic object in the game. I also changed the preset of the CapsuleComponent to overlap with the camera instead of blocking. Then I added OnComponentBeginOverlap to the spherecollider, but there's no overlapping event at all with the Capsule. Other colliders in the game generate overlap events with the sphere. I even tried to test the overlap between the two colliders in EventTick with the Function IsOverlappingComponent(), but still no overlapping event. Any idea what I'm not doing correctly here?
trim matrix
@plucky dawn For some reason I thought this is all that's needed. I don't tinker much with blueprints, so I may be wrong
tranquil bone
So if you have a savegame object which has a map of Names and Structs, then it cannot be modified.
the map cannot be modified.
plucky dawn
@trim matrix thank you for your answer. I checked the SpringArm and my setup is the same as the image you posted. I did some other tests and when the Character is moving, the overlap is actually detected. This doesn't happen with other no-moving objects. I will keep trying to understand what is going on with this collision detection. If anyone else has any other suggestion, please. Thanks again
twilit lily
Does anyone know how I could make my camera not rotate with a ball. The ball has physics on and I want it to roll.
haughty ember
check the rotation properties on the character, camera and controller (write "rot" in search)
@plucky dawn Not sure I fully understand your situation, but know that collision events aren't generated if they are collided on creation (rather, on spawn)
tight schooner
@patent crow if you haven't figured this out already... Your player character is calling the "fire" function on itself, rather than sending an interface message to the PlayerWeapon. In the most basic sense, you're using the wrong "Fire" node on the PlayerCharacter end. You need to find one that has a mail envelope icon on it, and set the PlayerGun as the target.
If it simplifies things, only the recipient BP needs to implement that interface. All BP classes will have the ability to send all available BPI functions even if they don't implement any of those interfaces.
twilit lily
Quick q, is there a way to have my collisions be the same exact size as the object/actor etc?
tight schooner
there's a "get bounds" node IIRC... I don't have UE4 open rn, but that'd be a way to get the in-world size of a particular component.
twilit lily
Thanks, will look around for it
trim matrix
Alright, so I have a player character, it was made out of blueprints, and I paid for it. It changes the character movement... and whenever I add anything to the character, it works like half the time as a client. Half the time I will be able to move around, the other half well... all I can do is jump and look around and (unrelated: get the leg break sound from "falling" even though the character is not falling.)
Is the blueprint broken or something?
tranquil steeple
not enough context to be able to say anything
trim matrix
ok ill look into it more
tranquil steeple
the character movement as in the blueprint code within the character bp, right?
not an actually replacement of the CMC (Character Movement Component) in C++
trim matrix
not actual replacement of the movement C++ code, within character
going through everything again, I guess ill be bound to find the issue eventually even though itll take forever
faint pasture
@trim matrix You are telling us almost nothing, you need to spell out what your specific problem is.
vale escarp
Hello guys so i have this problem in the 3'rd person character template, wen you activate cursor, the camera rotator is still active, and once you click on the screen the rotator disable itself (and is posible to rotate by Click and drag on the screen) As a solution i want to simulate a Click wen i make the transaction from the 3'rd person controller to mouse, or I'am open to any suggestion. 🙂
earnest tangle
There should be a way to turn off movement for it
vale escarp
i can force it to stop rotate, but i like the "Click and drag on the screen" to make rotation wen you have the cursor
earnest tangle
Right - so in that case you would probably want to stop the rotation, but enable it when the user is holding the mouse button down
vale escarp
Jezz dude 😄 tnx 😛 Gonna try this now
icy pelican
Hello, I have a Character with an CapsuleComponent(root) and AIController(both inherited) and when I call Move AI Task, it works perfectly. When I set Simulate Physics to true on the CapsuleComponent the Move AI stops working, it does nothing. My goal is for the movement to ignore the physics (I still want physics because it allows me to spawn a lot of characters in the same place and they make room by pushing each other). Any ideas?
earnest tangle
You can't have character+physics, they are mutually incompatible
icy pelican
how will i spawn them? in a way that the characters wont overlap? right now im spawning with "try to adjust location, but always spawn", and after i spawn a few, it just spawns the character inside another one, which cant happen :/
earnest tangle
not really sure if there's a good solution, you could try checking the spawn area and then moving the spawn location if there's something there
verbal bolt
why can't I override an instanced property array?
icy pelican
the idea was to push the others away tho
earnest tangle
afaik there's some kind of crowd sim in the AI stuff, maybe that would be able to push the others away
odd ember
@verbal bolt default values are buggy as fuck
icy pelican
im gonna check it out
verbal bolt
should I use something else?
ok, I though of doing so, but can there be some other way perhaps?
odd ember
looks like you're using structs anyway, so I recommend using data tables
you'll have to load in the data from the data tables anyway
verbal bolt
Thanks for the tip
@odd ember wow, found a strange thing. you CAN actually edit the array in child blueprints
you CAN'T edit them in a scene, but in child BPs you can
WEIRD
odd ember
@verbal bolt you can probably edit them but there's no guarantee that they stay the values that you set
I had the same issue that I set up values for an array, but once I hit PIE, the values would reset every time
restive tundra
How do I go about activating a boolean of single copy of an actor in the same level?
surreal peak
Depends on how you interact with it
restive tundra
I'm just trying to lock doors so that when the player enters a room, the 2 doors for that room set to lock, and when the enemies in said room are killed they unlock
surreal peak
So you want them to be false by default?
Before even playing?
If you click on a variable in your blueprint and you check the details of that variable
You should find a thing calls Instance Editable
If you mark that true then you can change the value on each instance (copy) in the scene
rotund ruin
I think I've seen this yesterday but I can't find it - I have a collision capsule on my pawn and I want to detect when it overlaps walls (static meshes). In order for it to work, all static meshes hit need generate overlap events true? is there another way around it? Like how the spring arm collision test works?
hazy fulcrum
Hey guys, not sure if this is a concern for the design channel or this one, but I'm trying to work out a mechanic in Blueprint.
I have a third-person camera inside my player character, attached to a spring arm component. I have the socket offset to the right side of the character, and I want to swap shoulders like so.
My thoughts were that, for this to really be a useful mechanic, I would want the crosshair to remain on the point at which the player is aiming, but I don't know how I would go about doing this. My line of thinking so far is that I would need to somehow either rotate the camera towards the crosshair direction?
crude jewel
@hazy fulcrum check first person template in Unreal Engine already have a built basic aiming System. You find a idea how the aiming will set.
Use Aim OFFEST
https://docs.unrealengine.com/en-US/Engine/Animation/AnimHowTo/AimOffset/index.html
This is basic..
Another is aim assest for aiming System

Afternoon guys! So our team are currently stuck on finding a universal way of making a character sit (to a snapped point) on key press and then stand and resume control again on key press. Now, I know there is a blueprint out there, I think it was from Git, where there is a chair and stamina system, we have tried that out and tried to adapt it but didn't work out for what we needed. We need a system where we can attach a point to any bench or moving seat (such as the smiler coaster attached) and the character will adapt that position and also move/rotate with the car. We did look at the approach of adding sockets to the train mesh and blueprinting the "attach to socket" thing but couldn't figure that out either...So, all you experts out there...what would be the best way to tackle this?
opaque elbow
I tested a lot of things these past 2 days with my inventory system. I played with breakpoints, and I event tried a new system for my inventory to work but I still have that bug... (Im still loosing my reference to the item)... I was wondering if you could help me with that 😕. I am really starting to think that its just a bug because it really makes no sense at all to me. So I was thinking maybe I can send you the project and you could check it really quick if you can find if there's a problem or not. The project is not really big btw. I know its a looooot to ask so feel free to say no if you don't want to, its ok 😛 Thank you! @odd ember
odd ember
I really don't wanna mess with your project tbh
@opaque elbow
I got my own projects to work with
but I honestly can't remember what your bug was
opaque elbow
It's all good my friend 🙂
odd ember
so perhaps you can mention it again
opaque elbow
ok
I had a copy of my text i sent
Sooo here's my problem: I have an inventory widget with 8 "slots widget" in it. Whenever I pickup an item, the inventory refreshes all 8 slots widget with some info like the image of the item and the actor reference itself (the type of actor). "look at the image" https://gyazo.com/c31e112a13e00ff912fedb93afcf4a62. When I select a slot in my inventory, it gets informations of that slot (like the item reference "type of item") and with that, i can click a drop button that will spawn an item based on the (item reference "type of item").https://gyazo.com/77d1b330056a88554d4d43747d7b9d93 And here's my problem... Everything works perfectly fine when I drop my item. The correct item is spawned and everything works fine but sometimes (RANDOMLY) its like if the (item reference"type of item") is NONE so when I drop an item, nothing spawns cause there is no item ref (so it doesn't know what to drop). But most of the time, everything works. Its just doing that randomly. Sometimes I can drop 20 items before I lose the item ref and sometimes I loose the item ref on the first item i drop... its really random...
I have no idea if this is a bug or what but i really need help with this... I have been trying to fix this issue for now 2 weeks and a half and I have looked at approximatively 50 videos and I still cant find what im looking for. (let me know if you need more picture or anymore informations "I will provide them")

@final vigil I would say sockets is the way to go. If it's not adaptable enough for your purposes you might need some kind of component system that contains locators and snap to those instead, but as a general implementation i dont see why sockets wouldnt work.
oblique gyro
ok so still cant figure out how to destroy this projectile and still have this part play
odd ember
@opaque elbow when you refresh the inventory you replace all references with an empty array
final vigil
@worthy dew i'll give it a second go, maybe i just missed something
odd ember
@opaque elbow do you have a separation between your logic for acquiring the inventory items and the UI?
@final vigil I second sockets as the way to go forward
final vigil
wait, is it possible to attach a character blueprint to a mesh with a socket that is also inside a blueprint?
opaque elbow
@odd ember What do you mean by a separation?
final vigil
or would you have to casttobp?
opaque elbow
This is what happens when I pickup an object
this is in another blueprint
Its the master item. And every item in the game has a child class of this one
@odd ember
When i refresh the inventory it does replace every reference with an empty array but why is the array epmty? ... Its shouldn't be
sometimes it works and sometimes I loose the reference to the item as soon as i drop 1 object
but sometimes, I can drop 30 items before I loose the ref
worthy dew
@final vigil that should work if you have read access to the mesh
odd ember
@opaque elbow where is the pickup event in your other graph?
@opaque elbow it is empty because you use Set Array before iterating over it
remove that node and that will go away
does that solve your problem?
opaque elbow
Would i need to set the array when the game begins?
i have already tried it and its the same thing
My pickup event is fired correctly when a linetrace hits and you press "E"on a type of objects that are collectable.
odd ember
yeah if you need to set the array to something set it at BeginPlay
yeah but what does the pickup event do
and how does it relate to what's happening in your widget
tight basalt
Someone knows easiest way to make mortar ?
calm dock
why does the item have functionality to add it to the inventory? 🤔
opaque elbow
When you pickup the item, it adds it to an array of item in the inventory and it show it in UI
calm dock
yeah, but thats bullshit design-wise
opaque elbow
is it?
here's the pickup function. its just doing the little stuff when you pickup an object
calm dock
You should invert it.
Instead of having a player ref in the item, the player should have "add item" function
opaque elbow
@calm dock Ok I will check that after I fixed this problem 😛
calm dock
your problem exists probably because of this
opaque elbow
hmm probably. But I dont loose the item ref when I pickup an item tho. only when I drop it
opaque elbow
maybe
odd ember
you should have an underlying array of items that are the "real" items
opaque elbow
ive never done an invenmtory before
odd ember
and then on top of that you need an array of "visible items" that are present in your widget
hazy fulcrum
@crude jewel I think you've misunderstood my issue, sorry. If you notice how the crosshair moves with the camera, I would like it to remain on the same spot that the player aims at regardless of whichever shoulder the camera is over.
odd ember
so when you add an item, you tell the inventory component to add the item to itself, and the inventory component should communicate to a separate widget that an item has been added
then the widget knows how to handle the item based on the struct and shows it properly
you do the same for removal
so in terms of you dropping the item, what happens? the item doesn't exist anymore?
opaque elbow
When I drop an item, sometimes it works and the item ref is ok, but sometimes when I drop an item the item ref is "NONE" so it doesn't know what to drop.
@odd ember
opaque elbow
with the item ref
odd ember
where does that come from
opaque elbow
2 sec i'l show you 🙂
opaque elbow
ok
odd ember
I want to understand how you are thinking about this
opaque elbow
My master item has a struct in it wich contains an item ref that is automatically set to itself on event construct
odd ember
it's really hard to read your code
what I can suggest is to rewrite the code for picking up and dropping items
when picking up the item, make sure the item you are picking up is valid
when dropping items, make sure the item you drop is valid as well
although it could be
opaque elbow
when i pickup an item its "Always valid" But when I drop an item, sometimes its valid and sometimes its not...
odd ember
is it always the item at the end that doesn't get dropped?
how do you check for validity?
opaque elbow
When I drop the item, I check if the item in my inventory array with is valid. https://gyazo.com/36e921910d56aca60ac6b895709b5362
Sometimes its valid and sometimes its not
idk why tho...
@odd ember
odd ember
have you checked through debug if it's always the last item that's not valid?
odd ember
the last item in the inventory
opaque elbow
no it is not
its random
dont mind tha graphics. there is nothing done yet https://gyazo.com/6e3b8a1b00d3e9510c944598e72fe194
it can be in the middle, the first one etc...
opaque elbow
ohh do you mean in the array?
odd ember
yes
opaque elbow
yes
opaque elbow
the first slot is 0
odd ember
and not slot 1
opaque elbow
yep
odd ember
where do you map the two arrays to each other?
opaque elbow
the array of the item in the inventory and the slots?
odd ember
yes
because I think your error is there then
that's why it would be better to rewrite the function so that you are sure that both arrays are added at the same time
and I think that also includes not resetting the visible array every time
I think that is causing you issues first
and then something else goes wrong on top of that
blazing ridge
generelly speaking, say i need to break and make a structure. whatever it may be, post process settings, stats for my player, or a brush löike in the picture.
is there a way to streamline this process? i dont want to connect all of the pins on those nodes if i only want to change 1
odd ember
@blazing ridge use set members in var
blazing ridge
that will keep all other pins as they are and only change the ones i expose?
thats great, thanks a lot!
so this right here would take the brush, change the image, set the brush and leave all unexposed pins as they were, right?
or can i delete the Set Brush node at the end?
opaque elbow
https://gyazo.com/5170cb409b08c85748a31d135209e4fd every slots in the inventory, has a variable named "Slot" wich is set in the designer tab becasue the variable is editable. So the slot slected in the picture is curently the index 2 since its the 3rd one and the 4th one its index is 3, etc... After that, this "Slot variable is passed into the event dispatcher to my inventory (This is in my slot widget btw)https://gyazo.com/08e2875106b0ee6219c2d6c0ea9056d7 And then in my inventory, whenever I click a slot, it sets the inventory slot selected to the one I just clicked since I passed that "slot variable" and that I used a for each loop of every slots in my inventory. And this is how I know wich slot I have pressed. https://gyazo.com/adb7adb351ea8b750594c6e365ad65d1
@odd ember
twilit heath
@blazing ridge why don't you just call SetBrushFromTexture on the image reference there?
avoids the binding which are pricey even if they don't use a binding function
odd ember
@opaque elbow you need to make sure that when an item is picked up both of your arrays are updated at the same time. I don't need to see more code
blazing ridge
theres no such node to pull of from my image variable @twilit heath
also i was curious for all structure related sets
opaque elbow
@odd ember wich array?
the inventory slot selected?
@odd ember they are matching correctly
Because when I click a slot in my inventory, im printing the name of the item and its the good one
I have just realized that even when I dont drop an item it looses its item ref. I think it looses its ref by time passing... Idk why...
When I pickup the item, i can select slots and it prints the right item name and everythings fine. But after waiting arround 30 to 60 seconds it looses the "item ref" for some unkown reasons... 😕

Yes, ask your question and if anyone can help they will 🙂
zenith flame
so i was trying to use the template of the first person shooter to experiment a bit, and i was trying to make a bullet destroy another actor but its not working, why?
haughty ember
@zenith flame When explaining a problem (in general, not only in computers), try not to use statements like "not working". The more details the better:
1 - Is the bullet even colliding with the character? If you're not sure, you can either put a breakpoint in your event or add a Print String node.
2 - If so, print/check the other actor to see why the cast fails
zenith flame
@haughty ember where do i find the log?
haughty ember
@zenith flame you mean for print string node? you should see it on the screen. You can also see the output log: Window -> Developer Tools -> Output Log
zenith flame
@haughty ember So i don't think its even colliding, how do i fix that?
haughty ember
@zenith flame Collision settings. You should be familiar with them though, so you should probably read this first: https://docs.unrealengine.com/en-US/Engine/Physics/Collision/index.html

@haughty ember Solved it, understood collision correctly. I just didn't realize i didn't have a collision box on the bullet. Thanks for the help!

Hello , in my game i have a farming system where the player will press a button which will fire trace , if the trace hits an instanced mesh it will replace it with a blue print actor allowing it to be farmed , this approach gives me a bit of hiccups during playtime , can anyone help to better optimize this or find a better approach?
tight schooner
Things that could be slowing it down...
- "Get all actors of class"
- iterating through big lists/arrays
- Spawning an actor that has a ton of components or a heavy construction script
Hard to say what's slowing it down without getting into the weeds, so to speak.
Pooling actors is a strategy for cutting down on spawns/despawns. It means making an actor reusable -- having a "pool" of them and hiding them when not in use. Commonly used for projectiles e.g.
but you should first figure out exactly what's making it slow before trying any particular optimization

@haughty ember I have a third person template, i have a collider in the camera and I want to detect when this collider overlaps with the CapsuleCollider of the Character. They are defenitively not colliding on creation. The image shows the moment I want to detect the collision.
haughty ember
If they are not colliding on creation, it has to be the preset of the collision.
You can try to use a camera actor outside of the character actor, perhaps there's some issue with components in the same actor? but I'm pretty sure there isn't.

Has anyone been having problems overriding Input Action events in 4.24? i am getting inconsistent results. sometimes firing the pressed of the parent and only the release of the child, etc, keeps switching and is inconsistent on what will fire if it fires at all. I have consume input unchecked in the child
fair estuary
Unless I'm missing something, children inherit from the parent. What are you trying to accomplish @fiery sage ?
I've not experienced that personally Juan.
distant sedge
Instead of having Input Actions in a whole hierarchy, just have it in the parent and the parent calls a function on press / release. Then the children can override it.
weak idol
@distant sedge ya that's what i'm considering doing, but can't choose to consume input that way
i could have the virtual function have a return value to say if it should run the actual one i guess
just hate hacky shit
distant sedge
You can consume the function call, if you don't call to the parent function in a child.

@opaque elbow if you sit still in the game for 30-60 seconds without moving or anything do you still lose it?
sour lily
twilit lily
Errr, I came to this realization that colliding with two boxes, if I leave one is in air is set to false. Any idea how I can fix this?
Meaning, if I got to a corner, where multiple box collisions can be then leave it, it runs the exit collision and thats no bueno
opaque elbow
@odd ember well if I just start the game and dont move like that there's nothing in my inventory soo i can't lose anything since there nothing
I have to at least pickup an item
odd ember
@opaque elbow well yeah pick it up and leave it
opaque elbow
but let's say after picking up an item 30 to 60 sec after I loose the ref
yea
i loose it
odd ember
do you have item decay in your game
opaque elbow
whats that?
odd ember
like do you have items like food that over time self destruct?
opaque elbow
humm.. I have a hunger system
And i have apples that gives you hunger but nothing destroys over time
odd ember
can you destroy items in any way?
opaque elbow
by picking them up

This bug still exists in 4.24.1: https://issues.unrealengine.com/issue/UE-28811
Quick rundown of the bug: When the mouse cursor is shown, mouse x/y events don't fire properly unless the LMB is held down
Are there any good workarounds to this? I created a custom mouse widget that just gets set to the mouse position every tick, then set the playercontroller to not show the cursor anymore, but that feels laggy. Its possible the framerate of the PIE isn't great, but I'm curious if there are other, more reliable ways around this issue.
odd ember
so if you're destroying them, and you're having a reference to them
that sounds like the issue
opaque elbow
Im setting a varible in another blueprint before I destroy the item tho
odd ember
that doesn't matter
odd ember
so your inventory consists of an array of class types?
twilit lily
@odd ember When you have a chance can you help me with a small bug?
odd ember
sure just ask
twilit lily
So I have an issue with this
I enter 2 box collisions
and leave 1
then I cant move
even tho I'm still in 1
It makes sense
Just curious how I can make this work as intended
odd ember
what do you want to do?
twilit lily
This i just a check so the player cant move in the air
I'm not using a template so I can't call is falling
odd ember
what does that have to do with overlaps?
twilit lily
Well my idea that when the ball overlaps a collision is that they're on the ground
But I didn't take everything into account
So do you have a suggestion to fix this or an idea for a better is in air system?
odd ember
I have no idea about the context of what you're trying to do
like what is the game
what does being in the air mean in this
can you jump?
are you playing as a pawn?
twilit lily
Yup, as a pawn
Just a ball
So the player can't jump or move while in the air
Thats what I need to accomplish
odd ember
I would recommend a character movement component
hollow cape
odd ember
I honestly thought it was animBP
spark delta
Just reparent your pawn to make it inherit from Character, it is defined as a pawn with movement capabilities. Checking if the Character is in the air should be at least easier than checking if a pawn is in the air
Characters already have an inherited movement component too
twilit lily
Alright, thank you guys
spark delta
apologies for the copy/paste, but I have been looking everywhere for a solution to this and I've only found one, non-ideal solution to this (the one I'm using).
This bug still exists in 4.24.1: https://issues.unrealengine.com/issue/UE-28811

Its possible the framerate of the PIE isn't great, but I'm curious if there are other, more reliable ways around this issue.
This seems like a bug that would have more exposure, since its so easy to replicate (turn on show mouse cursor in a game that also captures mouse x/y events), but also such a common feature
I'm trying to create a twin-stick style hack and slash, kind of like battlerite if anyone is familiar. I need to be able to turn (mouse X event) as well as see my mouse for really precise movement and abilities
I think the other solution I have is to allow mouse to be shown, and handle character rotation per frame by setting them to face my mouse each tick instead of on mouse events, but that feels not ideal either because it is so much extra work each tick
opaque elbow
OOOOMMMMMMMMMMMG
@odd ember
AFTer 4 fcin weeks
I fixed it
Bro like you dont understand how much time and effort I have put for that
odd ember
so what was it
opaque elbow
Thank you sooooooooooooooooooooooooo much for taking the time and helping me man 🙂
you know when I told you my ref was the ref of a class? I actually forgot to do that when i did the code because I was testing some shits a long time ago and I forgot to get the class instead... 😂
Now im getting the class and everything works PERFECTLY
FINE
odd ember
glad I could help
unborn maple
So, i am using matinee to move a boulder for a death trap, but the boulder is not spining -90 degrees until it hit a wall. any ideas how i can fix this? i know it work when i do it on tick but there no way i can do tick if i want to use it as a trigger.
odd ember
matinee still a thing? I thought sequencer was all the new rage
unborn maple
lol i am new so i am just using what i know
twilit lily
@odd ember So I cannot seem to get my movement to work at all with CharacterMovement (Inherited)
Actually its the is falling
The is falling always returns true
unborn maple
i guess i can look at tutorial on level sequence and see what that about
spark delta
@twilit lily does your mesh have gravity enabled?
I just tested with the unreal mannequin and falling is set correctly
twilit lily
Okay, let me try something then
Yeah its just always returning true
Hmm, so I figured something out, not working but it will lead somewhere
gusty shuttle
Hey guys, in your whole history of using blueprints, have you ever come into a error from using the same ref (sprite) for multiple ref connections like below?
I don't think I have but just checking with you guys. Im about to make a bunch of connections so I wanna know if I need to make a GETer ever time
twilit heath
thats fine
every pin on nodes connected via exec wires updates when the exec runs through the node
spark delta
Whether you copy it or not, it calls GetSprite only when it needs it so it makes no difference
twilit heath
and stays valid until the next time it does
gusty shuttle
Yeah that's what I was thinking too. All should be well. I never ran into a error or something messed up from calling a ref too many times
twilit heath
every node that is not connected via exec wire directly evaluates whenever the exec node its connected to is executed
trim matrix
How can i set a timer in my behavior tree or in my ai controller where if the enemy doesnt see the player, it generates a random time and then plays a sound?
twilit lily
Okay so the issue is that simulate physics has to be off on the Capsule Component, which I was fine with however if the sphere has simulate physics on it just rolls away from the parent.. and off the camera.
spark delta
You can turn off physics on everything, but make sure that enable gravity is on your root component
@trim matrix does the Delay node work for what you need?
twilit lily
Well I suppose I could turn off the physics but how can I use the Character movement to accurately move this ball?
spark delta
You can create a random time to delay for, then play your sound after it
I guess I'm not sure what you're trying to do. Why do you have a capsule component if you're just trying to control a ball, shouldn't you have a sphere collision component?
If you're trying to control it with like angular momentum or something, that might need another solution than charactermovement, or a subclass of it or something
trim matrix
@spark delta is there a way to determine if a blackboard entry is not active as ai perception?
twilit lily
but only way to get that is by creating a character
spark delta
Is your movement scheme more complicated than "move left/right/up/down using wasd"? If so, I would first try to create a new blueprint of CharacterMovementComponent and implement the correct type of movement in there then add that manually to a pawn to be able to control it as well as get your isFalling feature
@trim matrix Unfortunately that is beyond my experience level, sorry :(
twilit heath
CMC supports falling just fine out of the box
and i think a custom CMC is a terrible idea if you're just starting
that class is ludicrously large
twilit lily
@spark delta It's really not, it's a 2.5d game with a bouncy ball lol. just need some semi-realistic physics.
lofty kernel
guys my level blueprint is not going off on my build anyone know why?
spark delta
I think CMC doesn't give him the kind of movement that he wants though- which I think is physics based ball rolling movement?
twilit lily
@lofty kernel We need way more info than that..
twilit lily
Did you set it to be the default?
spark delta
Anything specific you can give us. picture of your blueprint, what you expect it to be doing, any error messages you're getting, etc.
twilit lily
^
twilit lily
What is telling your level to load tho?
twilit lily
Is that on a widget blueprint?
lofty kernel
yes
lofty kernel
thanks so much! ill check it out, sorry for interrupting zlo and Tim
trim matrix
is it possible instead of ai perception, i can use line trace to see if the raycast from my character hits me, then set a blackboard?
twilit lily
No problem
spark delta
@twilit lily Just to not let your problem go away without a resolution- As zlo mentioned, I would highly recommend trying to make the movement work with a basic CMC. Its a pretty well formed class with most of what you need for movement in there somewhere (including moving with wasd, jumping, etc). If that doesn't work, you can create your own custom CMC, but you'll lose some of the features of the CMC by overriding how it handles movement
twilit lily
I've never tried that before, how can I create a basic cmc?
spark delta
Its default on your Character lol :)
Its that inherited CharacterMovement Component on your new character
spark delta

Haha, sure hope so

Hi. I'm trying to figure out what is modifying the position of my UE4 actor's camera boom. How would I go about debugging this?
odd ember
@trim matrix how do you mean? the camera boom itself is a spring arm, so it'll act as a spring and retract when necessary
still salmon
Hey, anyone have any idea how I would lock a character to a particular object while its moving?
trim matrix
Yeah I know that. I was talking about how I have something set to change the rotation of the camera boom when targeting, and for some reason, the camera is shaky, which is why I was wondering if there was a way to find out what modifies that value
minor karma
hi, i'm having this issue rn
i'll keep setting the game mode and all that, then save and exit to try refresh the editor, and it just deselects everything
twilit lily
Hey @odd ember What can I call to move something if I'm using CMC?
Is there anything specific?
Or just add force?
spark delta
@still salmon can you use the AttachTo node to attach the character's root component to the other actor? I haven't done it before personally (not sure if you would then be able to control the other actor, since there would be a CMC on that actor then, but worth a try
twilit lily
also @spark delta
spark delta
I haven't tested brand new characters in a while... but I'm pretty sure movement is included out of the box. After you reparented your actor to be a character, you should just have movement abilities by default
iirc, anyway
spark delta
I'll create a new test project to see if I can get more detailed information really quick

I'm sure that this question gets asked a lot, I'm new here and i've been trying to make an interact door to work without this glitch that i've been running into. If anyone can help that would be awesome! Here is my Blueprint and here is a gif to show the glitch i'm running into.
The first open always plays like it's in reverse but it shouldn't do that

spark delta
Try toggling the default state of DoorClosed
jade widget
@limpid lotus yes 0 to 90 on the timeline

@spark delta toggling the state didn't change a thing.

haughty ember
@jade widget you're probably confused about SetRelativeRotation. it does a rotation relative to it's parent, not to the current rotation. 0 probably means "open", so the first time it goes from 0 (snaps to open) then 1 (to closed).
unborn lantern
Hi, Im trying to have a cube move based on mouse input axis, my camera stays on top and the cube should move left right based on mouse, but if I use InputAxis and feed it to "SetActorLocation" I see a LOT of flickering in the actor. Do you know why and how to fix it?
I have a SetActorLocation in" InputAxis Turn" event
jade widget
@haughty ember So what should I change the node to?
haughty ember
you have various ways to solve it:
- Change the base rotation of the mesh. You can try to use scale and positioning. Probably not what you want
- Change the float in the track of the timeline to go from 1 to 0 rather than from 0 to 1.
- Use a "1-" (float-float) node from the "Door Open" value. This is probably the easiest/best way
tight schooner
@unborn lantern Does it move around or does it flicker in place?
haughty ember
@unborn lantern Define flickering? but I think you probably want to lerp the position rather than set it
unborn lantern
@tight schooner it flickers in place, then when I move the mouse it flickers while moving and sometimes he goes back and forth
mmm. I found out something
it works on one axis only
I mean up/down
when I connect also left/right is where it starts to flicker
like if he is getting conflicting inputs
tight schooner
You might need to show us your graph. (That said I've never dealt with mouse inputs so IDK how helpful I'll be.)
unborn lantern
my graph will be hard to show 🙂
its inside a bunch of other stuff
but I can stream it
tight schooner
what if you used Add World Offset / Add Actor World Offset ?
instead of set location
my wild guess is the mouse input values are just -1 to +1 on each axis and you're just feeding those axes directly into a Set Location?
unborn lantern
the arrow is the axis value of InputAxis
so im adding the axis value to the location
tight schooner
oh ok, you're doing your own sort of Add World Offset
where's the other mouse axis?
tight schooner
also wow Get All Actors of Class
unborn lantern
its just a test
I will move that out
the actor is always the same
this is the other axis
so the first is setting Y, the second X
but this one setting X flickers like crazy
tight schooner
your graph is all kinds of scary, lol, but theoretically it would work. Maybe there's something about mouse inputs that I don't get.
or maybe your execution flow is weird
but try detaching what you have from execution and try... Event Tick --> Add Actor World Offset
with Get [name of your input axes] both plugged into the X and Y respectively
unborn lantern
I fixed it
the problem was the "Negate" node I had in the first graph
was a copy paste of a SetRotation graph where I needed the Negate for other reasons
tight schooner
oh, lol
unborn lantern
thanks anyway for your input @tight schooner , when you said it should work, made me focus and find the issue
jade widget
@haughty ember What would I do with this? i'm sorry i'm new to blueprints
tight schooner
timeline hype
haughty ember
@jade widget other way around; 1.0f - the value. It has the same value as if you go into the track of the timeline and set the value from 1 to 0.
It's more math than blueprints, but yeah you need to get used it.
And you just plug it instead of using Door Open
@tight schooner and for good reason.
tight schooner
yeah, opening a door with a nice animation curve is a practical use for timelines
twilit lily
@odd ember
I've been messing with for a bit
Can't get the movement input to work at all
it does nothing

I've tried all sorts, low, negative, 100000000
50000
scale = 1000
scale = 1
The ball moves with force tho
odd ember
you're using this node yes?
twilit lily
yup
Wait a sec
Hmm, I think I see an issue
So I have my CMC
I put it on my pawn
my pawn spawns by a player start
So I noticed that my InputAxis for A and D doesn't work on CMC
but it does on my pawn
@odd ember ^
odd ember
that doesn't make sense
wait
are you using a cmc on a pawn?
and not on a character?
odd ember
yeah but that's not how it works

patent crow
Could someone possibly point me in the right direction?
I'm looking to spawn a small mesh at the end of a linetrace that occurs constantly when a weapon is equipped.
The question is this: How would I go about using the impact position of a linetrace as the spawn, or socket, of a mesh?
prisma pebble
on hit location from the line trace
worthy dew
you probably dont want to spawn it every time, better to keep one around and move it where needed
prisma pebble
break the hit result, get the location (if that's what you want) and promote it to a variable. set it to a name that makes sense, like "TraceObjectSpawn"
i think
sorry sorry, get hit point, not location
patent crow
So spawnactorfromclass on weapon equip, save the hit location as a variable, and mark it as, per say, "lasersightlocation"
hit point, got it
prisma pebble
"impact point" on that node I think
you can do a lot with line traces, but keep in mind that they can be HELL in replicated systems. Can be very very expensive depending on player count
patent crow
Thank you. What kind of node should I use to tether the mesh's movement to the hitlocation? Also, I'm getting the impression I shouldn't use this on my weapon's event tick, so how should I go about having it change? I have a DoWhile(TrueOrFalse) Macro that I could probably implement, just not sure if it's feasible
Don't need any replication here, purely singleplayer.
prisma pebble
I'd actually recommend doing this as a VFX trick, not game logic
patent crow
I'd be open to that, I just have no particular knowledge about particle effects.
i just have a mesh which is two planes in an X pattern, with a translucent red mesh
As a diagetic version of a crosshair for most weapons
patent crow
no problem!

lol
Rival I'm not using any character movement
It wont work with what I want
spark delta
There's plenty of ways to overthink this, but I think in this case its just easier to just go with what the easiest solution is :)
Dang, that stinks. What was the problem with using a CMC?
twilit lily
Well, the simple fact its inherited to the character
and forces me to have capsule comp
so atm I'm using the ball template from unreal
with some minor changes
spark delta
ah, gotcha. You could set the half height of the capsule to the radius of the ball and you'd have a sphere :)
but if that ball template is closer to what you want, definitely go with that
twilit lily
It is a bit easier to manipulate
plus the CMC has a lot that I dont need
let me give you an idea of what I'm trying to achieve
spark delta
Oh, with that max speed thing- if you also want to clamp speed due to gravity, you'll need to clamp speed in tick instead of after adding the force
twilit lily
Hmm
spark delta
Otherwise I could see some funny things happening where you're falling with no input, gaining crazy speed, then when you add input again suddenly your speed is limited and you come jerking down to a slower speed
spark delta
oh wait- I think InputAxis calls every tick.. So its already ticking that lol
Never heard of it
spark delta
like 2D gravity platformer or something? Can't watch the video atm
twilit lily
Yeah more or less
You just move a ball around
oh and inputaxis does tick
So I'm still unsure as to how I can clamp this exactly
physics was never my strong spot
pine trellis
Does anyone know how I can fix this error my project wont open any more
spark delta
something like this should work @twilit lily
You could reuse that CharacterMovement pin if you like the look of that better too
Oh, you're not using character movement lol
spark delta
give this a shot @twilit lily
That capsule component is just whatever your root component is
in my case I was already in a character, so it was a capsule
twilit lily
Works perfectly
Thanks @spark delta you've been a great help today
Let me know if you ever need any help 😛
spark delta
That's my secret- I always need help

Haha xD

That should clamp the magnitude but keep the direction
You can also clamp2D if you want to just worry about 2 dimensions

Hi guys, anyone work with level sequence?
Mine would play but it won't fire the events unless I went to sequence editor
@trim matrix maybe?
I will try that 🙂 thx
@trim matrix where do you find that?
Also my event fires with no problem
but I had to bring the sequence to the editor
it will not fire any event when I open the project and just play the level
oh, I may just be wrong, I vaguely recall someone recently went through a similar problem, and that was their solution. It's basically your variables on your blueprint, if the sequencer should have or not access to said variables. But I may just send you on a wild goose chase, because I don't use blueprints only C++ actually...

Hello everyone. I'm in the process of creating a leveling system for my game. What I am having difficulty with is adding a skill point after every other level without it adding 0.5 per level. What would be the best way to achieve this?

The simplest would be to use % modulo, right? 🙂 If the level is divisible by two, do something, if it's not, skip something. You can also look into data tables, it may be overly complex unnecessarily, but depends on your design goals @potent citrus

I have a question, if i wanted to play a sound when my enemy is looking for my player, would i put it in the controller or behavior tree?
@trim matrix There should be a behavior tree task to play sound already available...
So I guess you can add it to the behavior tree
how would i stop it from overlapping?
tropic tide
Didn't try behaviour trees yet, but maybe a delay?
trim matrix
There are several different states for checking the status of our behavior tree node: start, in progress, failed, completed
is it possible to create a new task for playing a cue or should i just use the built in play sound?
ideally you would have a decorator that checks a condition, and play the sound only when start stage is about to kick in
it depends on the overall design, if it's a simple game, you can bypass behavior tree entirely
what do you mean bypass?
Don't use behavior tree at all
all it is is a robot chasing you around a house and you gotta escape before he kills you
but if you have an AI controller actively required for a proper flow of the game loop, then a behavior tree is an elegant solution
in its simplest form related to behavior trees, a decorator is a condition that if it's true allows a task to start running
if the decorator check doesn't pass, the task doesn't need to run and is skipped until the decorator check passes at some point later
You can use a decorator check for: is sound playing?
Or a decorator check for: did I start looking for the player, me the killer robot 😄
@trim matrix
Ok question
let's say i want to add in a stun gun to make the robot flee whenever it is hit
is that possible with behavior trees? Also #gameplay-ai please

How do I replace the inherited movement component in a character class?
trim matrix
I see, so the inherited movement component is just written in C++ and inherited in a C++ character, then you create a BP child class of the C++ character?
tranquil steeple
yes
earnest tangle
Depending on what you want to do, you could set the movement component to "custom movement" which effectively disables most of its movement related logic
earnest tangle
it doesn't but it would allow you to do movement logic yourself (again somewhat depending on what you're trying to do)

trim matrix
yes because it's only outputting the value on w/e u put in the timeline
for example X might be 0 - 100
so tree falls on 0 1 0 then 0 2 0 then 0 3 0 and so on until 0 100 0

@tight schooner yeah thanks, that helped. i changed it so im using a breakloop now. however I think i have another issue with the equal check im doing.
im not the best at vectormath or anything like that. but im trying to get it so the meshes i spawn are not so close to each other.
so what im doing is I check if the generated vector is equal to one thats already in an array. But i dont know if that check is really doing what i want.
my tolerance is set to 0,01 and i tried some different values but cant confirm that it works
trim matrix
I am not sure if you can dynamically change the value on timeline
opaque elbow
I want my tree to fall in the direction the player is looking when he has cut the tree, but when it is falling the tree doesn't follow the player
trim matrix
ok
opaque elbow
im not sure how to do that tho..
trim matrix
U have to do something with forward vector i suppose...
opaque elbow
how do i get the look at rotation?
trim matrix
Find look at rotation
then since u just want to rotate in one axis
split the structure pink
and get either x y or z... im not sure which one untill u try
Start is the tree location
target is the Player location
trim matrix
nw fam let me know
Oh btw
Take one of the value (X, y or z) im not sure which one rotates
Then invert it
So multiply it by -1
opaque elbow
ok ty 🙂
odd ember
if it's the direction the player looks in just take the pitch of the findlookat
you don't need the other values
oblique gyro
so is there some way to animate the set material node so it changes between 2 materials smoothly
opaque elbow
maybe blend with a timeline idk
trim matrix
@oblique gyro I am blending 2 textures for my cooking game later on
dunnoe about 2 materials, i mean most likely there is, but I am really newbie at these stuff
trim matrix
What are you trying to achieve anyway?
oblique gyro
when a projectile hits a shield it changes the material to a red one then back to the default one
i want to make it smoother so it doesnt just snap
trim matrix
I don't know how you plan to do it but if I were you, I would make material instance where I can control the color
from there on, i can just smoothly change the color with timeline
oblique gyro
yea
trim matrix
share the screen shoot
oblique gyro
like of what
trim matrix
your material
oblique gyro
the mat bp?
trim matrix
yes
oblique gyro
sec
trim matrix
If it's as simple as overlaying color, deffinitly use parametre
oblique gyro
trim matrix
Ahh yeah man
that's easy...
Right click on the blue color
Make it a parametre
Convert to parametre
trim matrix
U have to make material instance first
Rightclick on ur material and click create material instance
oblique gyro
yea ik
oblique gyro
of?
oblique gyro
yup
trim matrix
btw can it be fix value?
as in
it will always be blue to red
then maybe red to blue
oblique gyro
yeah
trim matrix
but not any other color
oblique gyro
yeah
oblique gyro
which
trim matrix
If u want it to change to other color, i think there is naother way.... but u cant use timeline unless it's a fix value
Make timeline in your bp
i dont know where u want to put it
on ur player/target/
Obviously on the event where it take damage
oblique gyro
player
trim matrix
yea make the timeline where u see fit
i would say when player take damage
Right click add timeline
oblique gyro
yea
