blueprint

[gentle urchin]

I see

[marble echo]

theyre less cards and more events i guess

but i felt cards was a good way to describe them

i wanted the ability to shuffle and add and remove them like a deck

[gentle urchin]

ah i see

[lucid nebula]

hey guys i got a question, so im making a game like r6s and wondering if theres a way to make AI on certain teams and shoot AI and players not on their own team

[spark steppe]

obviously that's possible

[lucid nebula]

well if i asked about it that means it wasnt obvious to me

[lime cairn]

a bit unrealistic, I remember getting popped in the back of my head when playing R6 Rogue Spear

[last abyss]

you just have to add a variable to your ai, then when it detects another ai, check that variable and see if its equal to the variable on this ai, if its not the same, then you know they're on other teams

[lucid nebula]

ty

[gentle galleon]

figured out

[steady night]

https://gyazo.com/8d94dca7ae2b3395d043f8ba6b705ca6

can i destory emitter based on a delay timer instead of auto destroy ?

[gentle urchin]

perhaps set lifetime ?

not sure if that works for emitters, but i'd think so

[steady night]

lifespan ?

[steady night]

target is actor

so no.

[gentle urchin]

a bit surprised one cannot set lifetime on a component

[obtuse herald]

lifetime is an actor thing, yes

[gentle urchin]

would be handy for those who like to create/destroy them on a whim

[dawn gazelle]

Could spawn a niagara actor instead, then you could do a lifetime on the actor spawned.

[steady night]

https://gyazo.com/6b8237dfa9cfd94bf050759775318346

dosent work

[gentle urchin]

It could already be destroyed ?

auto destroy is still ticked

[obtuse herald]

you could also spawn an emitter if you use cascade

[gentle urchin]

but emitter dont do lifetime! 😛

being a component

[steady night]

auto destroy dident change it

aye, so its a no go

[gentle urchin]

lifespan is just a timer tho

[obtuse herald]

the naming may be confusing, but 'spawn emitter' spawns a 'particle system component'

however 'emitter' is an actor with a particle system component as root

[gentle urchin]

Ah

That was gonna be my next suggestion

wrap it in an actor

toss a component to it

glad to see it already exist, and you're right, the naming is confusing 🙂

[steady night]

hm i suppsoe so

or rather

https://gyazo.com/a1c3a03f5f7c03cd9684bac3dcbfc1ca

how could i change the color of the effect ?

[obtuse herald]

kinda like this

[steady night]

aye cool ty, however changing color would solve it better for the next one aswell 😛

im kinda new so still learning

do i have to change the mesh materials colour ?

[glass stump]

how do i make an enemy move forwards in the direction it's currently going?

[odd ember]

take its forward vector, multiply by amount of forward, add to location

[formal wren]

I guess this has been asked a 1000 times, but how does one make interpolation truly frame rate independant?

[odd ember]

there isn't anything "truly framerate independent"

at least not in BP

[formal wren]

I know 🙂

but at least more consistent

[odd ember]

more consistent than what

[obtuse herald]

isn't the InterpTo node pretty consistent?

[odd ember]

everything is consistent

[formal wren]

If I use vinterp for example to move an actor from A to B it need 1 sek on 30 fps and 10 sek on 120 fps (extreme example)

[odd ember]

that's where deltatime comes in

[obtuse herald]

what is your delta-time input?

[odd ember]

it has to be variable per framerate

[formal wren]

delta time input is 'GetWorldDeltaSeconds'

[odd ember]

okay can you see if during debugging it corresponds to 1/framerate for the framerates you listed?

[odd ember]

something along the lines of 0.008 for 120fps, 0.033 for 30fps

[odd ember]

there's also a concern if interp speed varies between framerates, that should stay consistent

[formal wren]

Just tried setting a constant value for Delta Time and it seems to work

speeds now seem more consistent on different framerates

[obtuse herald]

what

[formal wren]

lol

[odd ember]

lol

[obtuse herald]

do you.. change your interp speed variable somewhere between these frames?

[formal wren]

no

[obtuse herald]

👁️ 👄 👁️

[torpid hound]

How are you changing your framerate to test?

[formal wren]

t.MaxFPS

This is driving me crazy. I'll create a project just for testing this now 😄

[gentle urchin]

The two interps handle it differently aswell, InterpTo vs InterpToConst

[formal wren]

Okay, just build a simple test map where I switch the framerate and stop the time an actor needs for a certain distance. And results are consistent

so I might have something else off in my project

it falls apart at extremely low fps

[main lake]

How to bind an event dispatcher to multiple Events please ?

[safe musk]

Hello every one, guy i have a doubt, How should i use the "Base pose" in a "Blend Pose By Enum" because my ENUN there are those options:

[dawn gazelle]

Can you clarify? Normally an actor would bind an event to the event dispatcher on the target actor that calls it, so whenever that event dispatcher is called on the target actor, the actors that have bound to the event will fire their bound events.

[main lake]

I need to bind my "Hour Changed Dispatcher" to 2 events : Event On Enable and Event On Disable

and the red line (Event) I can only connect it to one of the 2 but not both

do I need to duplicate the Bind Event a second time for the second one ?

[formal wren]

You mean you don'T have a 'Default' Entry in your Enum? You can just leave it blank. It will never be considered

[dawn gazelle]

Definitely not. What you're looking for is just for the logic to fire both checks at the same time. You can do the same with one event and a sequence node.

[main lake]

how ?

[glass stump]

Like this?

[safe musk]

@formal wren is it possible create a "default" in ENUM ? how i can define a "default" in this condition ?

[dawn gazelle]

On the event that's bound, put a Sequence node. One the first part of the sequence do your first == branch check. On the second part of the sequence, do your second == branch check.

[formal wren]

Show the ENUM definition

[safe musk]

@formal wren

[main lake]

Like so ?

[safe musk]

i can do this ... if is not those option it is "default" ...

[formal wren]

You don't have to have a 'Default' value in your ENUM

[odd ember]

of all the combinations you could have picked

but in principle, yes

[dawn gazelle]

No. This would mean the bottom check would only ever execute if the top check was false. Based on what you were saying, you wanted both checks done regardless of what the other one was as you wanted both those events bound to when the event dispatcher was fired. There's a node called "Sequence". It lets you run things sequentially without having to put them all in a line like you usually do with blueprints.

[glass stump]

hmmm, it didn't work, is there something i need to add?

[odd ember]

values? an actual forward vector?

[glass stump]

so like 'current rotation'? if that's a thing, lemme check

[odd ember]

also you're adding an offset

[glass stump]

get base rotation offset maybe

[odd ember]

get actor forward vector

[main lake]

Like so ?

awesome thank you 👍

[zealous fog]

Sequence nodes are the best

Also for do once events they're useful

[glass stump]

ah ha, that may work ,i'll try it, thnak you. :)

[zealous fog]

You can use them like this, it will fire off 1, then 2. Next time the event hits it will only fire off 2

[glass stump]

hmmm, nope the enemy still chases after the player.

i just want it to go in the direction of the player and then continue onwards.

[odd ember]

well you left that part out

[glass stump]

well, it's kind of complicated and a separate part of what i want it to do.

basically, i just want it to move forward based on whatever direction it's going.

[odd ember]

but that's kind of part of the context

[glass stump]

true true 😅 good point

[odd ember]

find look at rotation > forward vector

[glass stump]

Like this?

wait wait nevermind

i see what you meant

[odd ember]

sorry look at between the position of your AI and your player character

[glass stump]

Hmmm, maybe it's because I previously used an AIMoveTo.

[odd ember]

yeah if the task isn't done then it won't move

[glass stump]

is there a way to interrupt the task?

[odd ember]

also keep in mind 10 units = 10 cm

[glass stump]

oh whoa, yeah, i just changed it to 100 and it kind of teleported.

[odd ember]

that's what set offset does

if you want it to move, use another AIMoveTo

should override the first

[glass stump]

yeah, i was thinking that too, but i just tried it and it caused the AI to move into the center of the map instead. (which is an imrpovement to be fair haha)

[odd ember]

well you didn't add the location

so now it just takes the forward vector from 0,0,0

[glass stump]

Like this?

[odd ember]

add it to the end result

[tulip mason]

Yeah, that'll literally say go to the position of the forward vector, which is always between 0 and 1, so pretty much 0,0,0. Or add that forward vector multiplier to the actor location so it moves forward from the actor location instead

[glass stump]

@odd ember @tulip mason This is great stuff, thank you! :) This explained it really well, I get what you mean now, I'm just working out how to implement it.

[odd ember]

think of the forward vector, like any unit vector, as a direction

that means it will always have a length of 1

and as such when you multiply it with a value, you get a distance in the direction of the unit vector

[glass stump]

ooooooh! I think I see what you're saying, it seems to almost be doing what i want it to!

[odd ember]

almost as if math works

[glass stump]

the problem with it currently is it stops when it gets to where the player was at that time.

whereas i just want it to continue going forward. like a homing missile that's lost it's tracking.

[odd ember]

add more distance

[glass stump]

i've tried a few things but none of it is working, so may i ask what your recommendation on how to add distance is? i tried following the method you used above, but maybe i'm using the wrong nodes perhaps....

[obtuse herald]

bump up the value with which you are multiplying the forward vector

[odd ember]

what distance are you multiplying with right now?

[glass stump]

wait that's my problem

the get actor location, right?

[obtuse herald]

why are you multiplying the forward vector with your location?

[glass stump]

I'm trying to get the enemy character (this BP) to move in the direction of the player and then keep going.

[obtuse herald]

that was right

just change the 10 to something way higher

[glass stump]

hmmm

[glass stump]

for some reason the enemy just stops instead when i set it like this.

[obtuse herald]

mmh

try setting the int value to 1000

and add the player location instead of self location to it

[odd ember]

most likely the AIMoveTo cancels out because you're hitting beyond the navmesh

[glass stump]

OH MY GOSH IT WORKED

I think

I had it at 6000 and it just stopped still, why did 1000 work!?

[obtuse herald]

6000 is probably out of nav mesh and the ai ain't even trying to get to that point then

[glass stump]

ahhhh

[obtuse herald]

but 'Simple move to' might actually

[glass stump]

Oooh, maybe I should try that!

And thank you very much all of you! :)

[obtuse herald]

you're welcome

[glass stump]

I tried a few months ago to do this and couldn't, so I appreciate this immensely!

[obtuse herald]

if 'Simple Move to Location' doesn't work there is also a 'Move to Location' node

it has a lot more parameters avaiable

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/AI/Navigation/MovetoLocation/

[glass stump]

Ah, thank you I'll try that! 'Simple Move to' didn't seem to have any difference.

[main lake]

I have a small problem (as I think it could be improve). So I'm using my variable "Hours" (replicated variable) on my Binded Event to call the binded event / dispatcher "HourChangedDispatcher" and printed when the Box Collision is enabled when receiving the call from the binded event but instead of printing only when the Hour variable change it prints all the time (it looks like each time my timer update (so almost once per second).

I use the OnRepHours function to call the bind event "HourChangedDispatcher".

I tried to replicate only if the old value isn't the same as the new one to not overload my print system but it doesn't work (See screenshot below)

[glass stump]

I played around with a few of the options but that also worked the same way. I suppose I just need to work out how far I can push the integer with the navmesh.

[obtuse herald]

interesting

I thought 'Allow Partial Path' would do the trick

[glass stump]

I thought that too, but it just continued to stop still for some reason.

Maybe I need to connect it to something I wonder.

[glass stump]

YES DID IT!

Thank you so much!

I accidentally increased the acceptance radius instead of decreasing it!

[main lake]

How to Enable and disable collision on Box Collision please ? Like NoCollision works perfectly for disabling it but Enabling it make it we can't go through anymore and get the overlap event like before and in the "New Type Property" there's no option for "OverlapAllDynamic"

[silk hinge]

Hey guys, I'm having a little trouble finding something, Like I literally just want to stop running a behavior Tree, The "Run behavior tree" node set up with no value dosent do anything, any ideas of a node ? I can always run an empty bevior tree to make the AI stop, but I'm pretty sure there is a "Stop running behavior tree" node, right ?

[fluid dirge]

I'm trying to understand how the ThirdPersonCharacter blueprint rotates the camera boom. How does Add Controller Yaw Input "tell" the camera boom to rotate?

[main lake]

Does anyone know if a replicated variable is only replicated when it changes or it's replicated every frame, because I'm using a Binded Event that I call on the OnRep function of my variable and it's spamming the string with a printString I told it to print, so that's why I'm confused on why it's printing this much even if my variable isn't changing this quick (my variable change like every 20 to 30 sec)

[dark crow]

Pretty sure the Server stores the Replicated value and if it's the same it doesn't Replicate it again

[gentle crest]

Hey I have a strange issue. I created a blueprint with a light that turns on when a generator is filled with gas. I want it set to stationary and or static because it doesn't move but no matter what it gives me this warning https://media.discordapp.net/attachments/225448446956404738/942989593668620389/unknown.png?width=1003&height=687

has anyone else had this warning before ?

[tight cargo]

anyone know how to make the character lock onto the person so I cant look around the character?

[main lake]

Then I don't understand why this prints all the time somehow (I'm in the OnRep of my variable)

[dark crow]

Well, it's sent over to the server ofc all the time, but it doesn't replicate to clients if it's the same value

[dawn gazelle]

Your function is likely constantly setting a different value for the hour. Assuming your timer value is incrementing every second, the timer value / 60 % 24 will likely not result in the exact hour that you're hoping for. Put some print strings around and you can see what your values are looking like.

Part of the problem is likely because you're using floats. When you're dealing with integers it usually just gets rounded out. So 1/60 = 0 rather than 0.01666 or 65/60 = 1 rather than 1.0833

[main lake]

my variable "Old Hour" variable is always at 0 somehow

Zoom

[gentle nebula]

How can i read a mesh/widget current material opacity through the actor blueprint?

[dawn gazelle]

Well if you're truncating after the fact, of course that's what you're going to see. Don't truncate the values before putting the value into the print string. That's changing the number from a fraction to 0.

[main lake]

yeah my Old Hour variable stay at the same value all the time somehow and even setting it to 6 to be equal to the hour variable at start changes nothing it keeps spamming the print string

[main lake]

When should I truncate it ?

[dawn gazelle]

Don't

[main lake]

so what should I do ?

[dawn gazelle]

I've told you - put the values into a print string and you can see what their values are. Don't put them into a truncate node - that changes the value from what it really is so you're not seeing the true picture.

[mild ibex]

so uh, my blueprint isnt receiving inputs even though i have it set to enable input and i know for a fact that input is enabled due to a print string
but none of the keybinds in that bp are working at all, even if i set a basic keyboard binding like shift or something, its still not working

[gentle nebula]

Anyone?

[main lake]

the values aren't the same you're right so how do I solve this problem as those 2 variables are floats

[crisp vault]

The cube can be attached to player and left laying around, so the safe location can move/change position.

[mild ibex]

nvm, forgot that after moving to perforce some things were changed, apparently my level BP just cut out the enable input stuff

[sharp rapids]

will creating separate Blueprints for every inventory item become performance intensive?
I'm working on an Inventory system and so far I've found two ways to go,
first being simply creating a new blueprint for every item
second is having only a few base classes and using data assets to change their properties.
The second one is obviously more convenient to work with but I find a lot more flexibility in the first one.
I'm using actors to store the inventory items, so an actor for every item in the inventory
My question is, will the first way be more expensive than the second?

[silent berry]

Are you talking, purely for example, doing something like having multiple weapons?

[sharp rapids]

Something like Minecraft

[silent berry]

Well going off the example of weapons, which could be applied to many other similar things, I've just found that making a master blueprint and then making a different child blueprint for each different weapon wasn't super performance heavy

[sharp rapids]

For e.g. If I have 50 items in the Inventory, either way I'm going to have 50 actors in the level
In the 1st way, I'll have 50 instances of different classes (each inheriting from one base class)
2nd way, I'll have 50 instance of the same class (with different data assets)
Using the first way increases the number of classes in the project, so for 100 or so items that's 100 more classes
So I was wondering If it was more expensive

[dawn gazelle]

Here's a way to think about it:
Your inventory component likely isn't going to be storing actors, especially if you're doing something like minecraft and you need to store 99 stone blocks in it.
Additionally, you can't really store actors in a save game, so you'd have to break down and reassemble each actor when you save and load them.

[silent berry]

well more classes doesn't necessarily mean more expensive. I'm not sure how exactly you're building your thing, so the only thing I can really suggest is just trying a sample of each method and seeing which works best for you

[silent berry]

This actually makes a lot of sense

[sharp rapids]

Well right now, I'm simply referencing actors in the inventory items array
I tried doing it with structs, but BP Structs are limited so I went with actors

I can't have functions in structs 😦

[sharp rapids]

I have an actor BP that stores the amount, item texture, etc. things
When I need to spawn an item, I spawn that actor and reference it in an items array
When done, I simply destroy the actor

[silent berry]

I see

My apologies @sharp rapids , I'm a dipnut and I actually completely misunderstood what you were asking for

[dawn gazelle]

Either way you're not going to be storing your inventory as actors in the end - that would be super wasteful and require too much additional code to manage.
You're going to end up with a structure somehow. That structure should be minimalistic - just a means of identifying the item in the slot and the quantity of them.
The identity of the item can even be a reference to the actor class (normally the purple colored reference) that would represent that item as an actor. Just make sure you use a decent base actor class that has details like name, description, etc. so you can look it up by using a class default object.

Having different types of actor BPs isn't really the limiting factor and it's fine to build out your items in such a way- but then that makes the limiting factor your management of said actors. Like, if you build a house out of 15000 bricks, each one of those actors will be making draw calls unless you have a manager set up to handle instancing of meshes.

[runic parrot]

Hi everybody! i want to remove all text but the numbers from a editable text box, is there an efficient way to do this?

[tight schooner]

It's possible to get parameter values from a material instance https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/MaterialEditing/GetMaterialInstanceScalarParamet-/

[dawn gazelle]

Easiest way I know of is using the Low Entry Extended LIbrary XD
It has a regex replace function that allows you to use a regular expression and remove characters from strings.

[runic parrot]

i was thinking on creating some method to do exactly that, but if there's a library for it already, even better

do you know how do i have to proced to get the library?

[fathom cobalt]

can someone help?

[obsidian ridge]

I want to make it so when a first person character clicks on a cube it makes it rotate

I use raycast? I'm not sure where to start

So far I have it working with a projectile and overlap, but it's too buggy that way

[tulip mason]

Well, I'd you click on a cube, you then have a reference to the cube based on how you clicked on it.
You could then have a timer that finterps your current rotation to the find look at rotation based on your location to the cube rotation that you clicked on. Probably using world delta seconds for the timer looping

Or the cube rotate,,?

[obsidian ridge]

Here's what I'm trying to do

It's working with a projectile

[obsidian ridge]

Another question

How come textures in the blueprint view port look fine, but ones it's in game they turn black?

[tulip mason]

Well I guess a line cast would work, I can't remember raycast bu it's surely cheaper.

You could then do a fast rinterp of 20-30.

[wicked osprey]

Hello guys. Where i should write cutscenes and entire game logic? In game mode, or level blueprint, or another actors?

In a sequencer I'd think

[crude dew]

Hi wonder if someoen can help me im sure it,s easy fix but after 2 hrs i finally thought I would ask for help.

I have a health bar but instead of using 0.01 for damage values from a gun i would like to use integers.

[faint pasture]

Don't save stored items as actors, save them as structs which can be used to spawn an actor when dropping/equipping (holding in hand)

[crude dew]

This is my current HP implementation.

https://blueprintue.com/blueprint/cc0z6lf_/

[faint pasture]

You need to choose whether you want your HP to ALWAYS be a float or int. Float is fine, you can round for display if you're worried about floating point precision, but int is ok as well

either way, you need to architect your HP and Damage systems to work with floats or ints

a health bar is going to expect a float but you can convert from into to float for it.

[crude dew]

As you see with the image it prints out 40 as 4000 is 40% of 10000

but im sure how to convert that output of 40 to a float to feed the Progres BAr

[faint pasture]

Current/Max

BarAlpha = CurrentHP/MaxHP

[native willow]

see smth suspicious?

[faint pasture]

That's assuming your bar expects a 0-1 range. You can make a bar that takes whatever numbers you like though.

[crude dew]

is it the x 100 ?

[faint pasture]

You want to convert those to floats tho before the divide

the outcome of 4000/10000 as an int will NOT be 0.4

[willow yacht]

for the progress bar i use this returns 0.0 to 1.0f value
Percentage = Value * 100.0f / MaxValue / 100.0f
value = health or whatever
max value = max health ...

[crude dew]

ok i removed the x 100 and it prints out 4000/10000 is apprently 0.0

[faint pasture]

#blueprint message

[native willow]

^

thats why you usually want to use floats

saves you a few headaches

[crude dew]

so use a float of 4000 and a float of 10000 ?@

[faint pasture]

You can cast an int to a float. Just make a float divide node and drag the ints into it and you'll see.

That will convert int 1 into float 1.0 so you can do a divide without rounding

[crude dew]

Ok this prints out 0.4

but set percent doesnt set the health bar.

so maybe i need to check the cast.

[faint pasture]

Does set percent expect 0-100 or 0-1?

[crude dew]

0-1 i think

[faint pasture]

check it, give it manual numbers

[crude dew]

just checked the progress bar widget it says in the progress section Percent and can go from 0-1.

[faint condor]

he just gave you the formula for progress bar lol

[faint condor]

here

[crude dew]

lol sorry maths never been my strong point ;P

[faint pasture]

It's either this or this x 100, if it doesn't work, something else is fucked

[crude dew]

ye im guessing the cast to the health bar widget isnt working as it prints out 0.4 correctly so it knows 4000 is 40% of 10000

[willow yacht]

isn't the function GetWidget() that returns the component widget?
also make sure you select a widget class in your component

[crude dew]

@willow yacht I have the HealthBar widget selected in the class component the text is showing the values but the slider part is not working am getting a float of 0.40000 now man i hate using progress bars lol

[willow yacht]

lol try to remove the progress bar and add it back again and compile the bp
or restart the editor

[crude dew]

odd even with a hardcoded value like this it doesnt work

[willow yacht]

lmao

[crude dew]

but the target is active when i step through the code. xD

weird i removed it and readded it and it,s all working now

thanks for the help!

[gentle urchin]

Could you've had a binding on it aswell?

easy to forget those

[rough cedar]

Is there a way to get a character to follow a spline forward direction without using a tick?

[gentle urchin]

Why would you not use tick?

If it's animation/movement, surely you'd want it as smooth as possible

[rough cedar]

I'm just trying to see if theres another way. I like to avoid ticks if possible

[gentle urchin]

Avoid it when it makes sense

in this scenario it doesnt

you could use a timeline, arguably easier to manage

Its still tick based, but the gating is handled internally atleast

[rough cedar]

Ive never tried that way. How is that done?

[gentle urchin]

Updating animation/interpolation/movement less than on a per frame basis can easily look very bad (unless fps is way above noticeable animation smoothness, in which you probably have the resources to just do it on tick anyways)

[rough cedar]

oh ill just use a tick

[gentle urchin]

You'd lerp towards the next splinepoint

and when you reach it (e.g. timeline completes) you'd check if there are more splinepoints

if so, restart the timeline, with the next splinepoint index as a target

[rough cedar]

If you think its better to just use a tick I'll do that

[gentle urchin]

I'd just use tick, but then again I'm used to gating it

[rough cedar]

ok I'll use a tick for now. If it becomes a problem I'll try this other method. Thanks!

[gentle urchin]

No worries! Gl 🙂

I'm playing about with a 2000m inverse sphere (ico sphere with normals flipped inwards) and I'd like to have a light source in the middle that lights everything up and casts shadows. A point light can't seem to reach the required attenuation radius to light the whole thing up. Just curious as to what my options are. Is there anything like in the Source engine skyboxes where you can essentially create a small diorama of a scene, light it and then scale it up with all the baked lighting data? A lot of this would be for background scenery purposes and playable areas could still be lit by a direction light when loaded in.

Any other suggestions would be appreciated too

[primal smelt]

Right you are, I'll ask there thanks

[ocean bluff]

Hello, I'm doing a blueprint where the tether mechanics behaves like a rubber band ( like a Bungee). It works quite well for the first player but when I play as the second player, the cable doesn't follow it in the second video. is it because of the endpoint of the cable settings? in the first video, this is what is supposed to look like

[gentle urchin]

I would think the entire component must be attatched to one actor, and end attatched to the other ?

instead of just existing in the world?

If thats whats going on.. cant tell from your screenshots

[gentle urchin]

Im seeing the ned being attatched

but not the start

ok nvm

i got it 😄

its the end having isssues

Try adding a socket to the mesh and use that

instead of end location

[ocean bluff]

It didn't change unless I missed something

[gentle urchin]

You may need to include a component name?

i'd expect this to work tho

opening project now

[ocean bluff]

This what happens when I put it in component name

oh alright

[gentle urchin]

the socket in the socket name, and the component (mesh component) in the component name i would think

cant recall if you could get sockets across all components in an actor just like that

This just worked atleast

[ocean bluff]

where should i put that on my blueprint

[gentle urchin]

beginplay

i would say

you can prob just use the existing cable component, and not the "add cable component" node that i used

[ocean bluff]

what's the reference for start pole and end pole?

[gentle urchin]

just two random components i had laying around

It would probably be the capsules or mesh components inside your two reference actors

or just root component or smth

[ocean bluff]

I've probably done something wrong haha

I tried to use the character reference variable for the parent and component but it doesn't connect

[gentle urchin]

It needs a component,.

so try to get one of the components in the char ref 😄

[ocean bluff]

oh yeah! I got it

haha

let me show you

[ocean bluff]

It looks like this

[gentle urchin]

sweet

so now its attatched

next up is attatching it to your desired location

or socket

there's a socket name input

avaliable 😄

I think you need to get the correct component for that to work tho

root component probably (?) doesnt have sockets

Not sure if its able to walk down its tree and find a matching socket... i would think not

[ocean bluff]

I tried to use this socket i added but it doesn't attach there

[gentle urchin]

use snap to instead of keep relative

for the attachment rule

[ocean bluff]

IT WORKS!

Thank you very much

[gentle urchin]

Well done!

[chrome nymph]

if i have a PlayerStart - i should not have a BP_Character, right?

in my level

(assuming i only need one that the player should control)

[odd ember]

PlayerStart will spawn whatever is set to be your default pawn

[tawdry surge]

Unless you place one and it's set to auto possess. But generally you pick one or the other

[surreal coyote]

I have a blueprint that consists of multiple light components and in another blueprint I'd like to toggle the visibility of all those light components. How do I do that?

Blueprint reference > Set Hidden in Game
doesn't work

[gentle urchin]

propagate to children

[surreal coyote]

Like so?

[gentle urchin]

No, the boolean

Check the propagate to children bool on Set Hidden in Game

with the original target

[surreal coyote]

Oops blind

Yep that does it, thanks 🙂

I've outdone myself on that lightbar

[gentle urchin]

noice!

I would think an emissive material could handle that

[surreal coyote]

Not quite the same effect as pointlights

[gentle urchin]

quite a bit cheaper 😛

you can check the light complexity of it

[surreal coyote]

Well

[gentle urchin]

😄

If its not a problem, its not a problem i supppose

i love pre-opitimizing

dont follow my example

[thin panther]

is that the assetville pack

[surreal coyote]

Yeah it is

[thin panther]

it looks sweet, it's essentially what I model my environments around lol

might have to nick the vehicles tho, never been good at those

[final kiln]

Good day I am trying to make a system that checks if the interface is open, but I do not know how I can do pro branch be informed whether it is open or not, how could I do this?

[surreal coyote]

I love the style of that pack

[thin panther]

its my favourite style, all of our projects get made in that style

low poly is underrated

[surreal coyote]

Why don't you just block input when interface is open?

[gentle urchin]

Interface -> Widget?

[thin panther]

yeah you could just disable movement

[final kiln]

and because the idea is that the user's movement will be deactivated when the interface is opened, because he will use the same movement buttons in the interface

[gentle urchin]

disable movement sounds like what you want then i think

[surreal coyote]

Yes

Check if interface is open in the character movements. If yes, block movement

[final kiln]

and if I use a branch it does this easier, because if the interface is open it already stops working the movement, if it is closed it comes back, but the thing is that I don't know how to pull the information from the interface that is open

[surreal coyote]

The information from the interface?

[final kiln]

Let me explain better, wait a bit

[gentle urchin]

On Interface Open -> disable movement?

What else is there 😄

You need to redirect your inputs to the interface?

Use a branch

IF Visible -> Interface
ELSE -> Add Movement

[final kiln]

I am trying to make a skill tree interface system where it is possible to move around inside because there will be many skills and with that a normal screen size would not be enough to show everything, so to give the player the freedom to move the screen and see the rest of the skills, but already made everything to work, just missing this issue of the branch, because I have to make it true when the interface is open and false when it is closed, so the screen movement script will only work when the skill interface is open

[surreal coyote]

Sounds like you need a boolean variable

[gentle urchin]

"Is Visible"

[final kiln]

Yes, but I don't know how to pull from one script to the other

[gentle urchin]

You have a interface reference (widget ref),

you simply provide functions in the widget for widget movement

[surreal coyote]

Default false, set to true when you open it, back to false when you close it

[final kiln]

is ?

[gentle urchin]

skilltree is an actor...

didnt see that one coming

Or is it?

looks like a widget unless you get errors

dunno if you unticked "Context" ..

[chrome nymph]

am i misunderstanding how event dispatchers work?

on my other actor - i am calling this actor's OnEvent function

however, it doesn't seem to do anything

[final kiln]

I tried this before, but it didn't work

[thin panther]

theres a node called bind event to, that you will wanna call on the first image

cause you have the event, but it isnt associated

[gentle urchin]

Yupp. If TRUE , forward the event to the widget
if not, then just act normal and add move input

[final kiln]

=/

not working

is ?

[gentle urchin]

huh

you can invert it if you like sure

then if branch is true, do movement
else do forward the input to the widget

[gentle urchin]

null ref

[final kiln]

it doesn't work, the same way as the other way, it just fills up the logs with errors

[gentle urchin]

you're accessing something that is not valid

this is the root of your problem

[final kiln]

that's the problem

[rugged wigeon]

I'm trying to use a data table to store my skill / ability data. Part of that data needs to be the icon used to indicate the skill in a widget. The desired type is just "Object" which is not compatible with data tables.

Any ideas on how I can store this kind of data in a table?

[tawdry surge]

Wouldn't the icon be a texture2d

[rugged wigeon]

ahhh set brush from texture. Yes that would do it

didn't realize there were other options. thanks

[prisma gulch]

I dont know why this error is showing

[gentle urchin]

you're not checking if its valid

it appears it is not

So you should probably ensure it is valid before trying to access it 🙂

And possibly have some fallback if its ment to be valid, but is not yet updated for some odd reason

[prisma gulch]

thanks but I solved it by creating the variable of CurrentWeapon which was declared in C++, but I was using the different CurrentWeapon

How Can add CurrentChamberAmmo and TotalAmmo like 25/100 or do I create a new text for TotalAmmo

[chrome nymph]

is there a way to make a retriggerable timeline?

[rugged wigeon]

use the append function of strings to join together the integer values and " / " in between

[chrome nymph]

like retriggerable delay

[chrome nymph]

thanks!

[gentle urchin]

Its still good practice to validate pointers before access. Also I'd suggest doing an event driven design on the UMG updating instead of a binding

[prisma gulch]

I dont know how to do that I am beginner

[faint condor]

use format text node and put this text inside {Health}/{MaxHealth}

[prisma gulch]

@faint condor where do I put the CurrentAmmo/TotalAmmo in the Format text node

[prisma gulch]

Ok thanks

[chrome nymph]

boolean i guess

[gentle urchin]

huh ?

just play from start?

[remote obsidian]

I have a problem re: procedural components in editor and persistence

I'm spawning components on a blueprint actor procedurally in the editor, I'm using call in editor functions to spawn these components.
The problem comes when building the app, the procedurally spawned components aren't included, aren't saved with the level.

One solution is to trigger all the functions I'm using in editor on event begin play, but then I'm adding a lot more calculations on app start that I'd rather have baked down in editor, I also can't cherry pick my component setups as they're regenerated on play (eg. random scattering)

Is there any way I can take my "AddComponent" dynamic objects and bake them down to fully static components that can be adjusted in the details panel when the blueprint is selected (eg as if I had added them using the "add component" dropdown in the details panel)?

Thanks!

[fiery knoll]

Are you spawning them during play or beforehand (eg in the construction script)?

[odd ember]

you can use SetArrayElem and SizeToFit, but you'll have to have a nonzero element at the end

[remote obsidian]

Missed this message, i'm spawning them in the editor, not specifically construction script but by calling "Call in editor" functions

[chrome nymph]

how do i make my game start automatically possess the player spawn?

[rugged wigeon]

@trim matrix There is no reason to pass an array as an argument to that function and then clear it. Make the array a local variable. It will be instantiated as an empty array whenever the function is called.

That being said, I'm not sure why you would ever need such a function. Seems kind of obscure.

[fiery knoll]

Not entirely sure, but I would say the approach you're taking isn't meant to work that way: an actor in the build will be made just like the base blueprint, with the properties you set in the editor. So added components would not be created as they're not a part of the 'template'. Why do you need the objects to be spawned as a component? If they're going to be static objects anyway, why not just spawn them as separate objects?

[chrome nymph]

does anyone know what i'm doing wrong?

sorry the deadline is super urgent >_< i need to compile it asap

its not automatically posessing the pawn

[spark crow]

do you have auto possess player enabled on the BP_Character?

[chrome nymph]

BP_Character isnt in th eworld

does it need to be?

i only have PlayerStart

i just enabled it to player 0 - doesn't work still

[spark crow]

that's as far as my knowledge goes unfortunately :p

[chrome nymph]

anyone?

i will literally paypal you 5 usd if you can help solve this

i need a solution like NOW T_T

this is what i see when i press start

anyone? if you can solve this in the next 5 mins i will paypal you 10 usd

[spark crow]

what exactly you see when you press play?

[chrome nymph]

this

only my viewport

[spark crow]

on the scene

[chrome nymph]

the same perspective as i was

when zooming around

[thin panther]

you are on simulate

change to play

[chrome nymph]

omg thank you

pm me your paypal address

i really hope i can package it in time

[thin panther]

nah i dont need paying

[chrome nymph]

wow thank you

[warm ermine]

If anyone could help me code this into my game but modify it work similarly to super smash bros (2:27) - I'd be willing to pay them for their work first 😮
I have to go to work soon but DM me if interested

https://youtu.be/aVfusKPUPqk?t=147

[odd ember]

#instructions and the job board section is the place for this

[odd ember]

have you tried #packaging ?

it might be that the project settings need to reflect the target platforms that you are building for

but I'm not sure

[chrome nymph]

was because i didnt have VS installed

anyway yikes, compiling takes quite a while huh 😛

[odd ember]

I think there's a joke about this between programmers

[maiden wadi]

5900x disagrees with your compile times being long.

[limber olive]

hey guys how can I use multiple "set timer by evenet" instances at the same time in a for loop? The engine only uses one and resets on each iteration of the loop

[odd ember]

you want a new event every time?

[limber olive]

yes sir

[odd ember]

remove the loop, tick the Looping box on the SetTimer node

[limber olive]

I need a new event not a single repeating event

[odd ember]

at least that would hack it to work that way

[limber olive]

Each timer has it's own unique delay

[odd ember]

otherwise you would need to spawn new objects for each item and handle the timer inside of each object

[limber olive]

So I should make a BP actor that plays a sound after a delay and auto destroys?

[odd ember]

yep

[limber olive]

that's really funky lol but guess it'll work

[odd ember]

or if the actor already exists you can just call an event on that actor to do the same

[obtuse herald]

You could also try start timer by function name

[limber olive]

I don't know how to set the parameters though

[odd ember]

the problem is that the timer isn't unique if it's inside e.g. a manager class

[odd ember]

in response to this

[limber olive]

It only gives the option for the name

[odd ember]

so it's a no go

it also violates the responsibility chain generally

[limber olive]

Also I think functions don't allow any delays/timers/timelines

[obtuse herald]

Yeah, but you falling it via timer anyways

Calling*

[runic phoenix]

Why don't you make multiple custom events, use Start Timer by Function Name, and a Select from int to the name

Mind you I don't know if that would work, just what I thought up

[obtuse herald]

Just create a new uobject st that point

[odd ember]

what happens if the amount of objects inside the array increases then? you'd have to create a new event per new object, no?

this is why it's better to let the object itself handle this responsibility

[limber olive]

yea the array size n is the amount of pawns

[odd ember]

no extra code needed

[limber olive]

no upper bound

[runic phoenix]

Yeah, but what's the goal here, trying to call events each on their own timer?

Just put the function in the object and the timer there too

[obtuse herald]

Calling the same event multiple times with different delays

[limber olive]

Yea I'm going the route of spawning an actor at this point

[odd ember]

Foreach (Pawn) -> CastToPawnType -> CallSoundFunctionWithCustomDelay

[runic phoenix]

Yeah then you'll need multiple objects firing that event

[gusty shuttle]

Anyone have an issue where you try to play/scrub through an anim in UMG and it won't frigging move?
Why is that and how do I fix it

[obtuse herald]

I would've thought that the set timer node would not override the previous timer but here we are

[runic phoenix]

Hey I have a question, I want to add an in-game pause, but still allow for my camera to move around smoothly. What would be a good way to do this? Is there a way to have multiple delta-seconds somehow?

[odd ember]

I believe you can have input keys trigger regardless of pause, so maybe that would work on its own?

[obtuse herald]

You can make actors not be affected by time dilation/pause

[odd ember]

sorry, input actions

[runic phoenix]

Yeah they do, but things like r-interp don't work when the game is paused, so the camera no longer moves gently

[odd ember]

how does it move?

can you show your code?

[obtuse herald]

Yeah world delta seconds probably doesn't get uodated

Use delta seconds of your tick instead

[runic phoenix]

Input movement is using Add Actor World Offset

[obtuse herald]

And set the actor to not be affected by pause in details panel

[runic phoenix]

Ok so I was on the right path creating the camera's own delta seconds variable

[odd ember]

you can use AddControlRotation instead perhaps? I forget what the default nodes for camera movement are in the TPS

[obtuse herald]

Yeah world delta seconds is literally the delta seconds of the world

[runic phoenix]

Also the focus gets blurry when moving while paused, but only near the original rotation when pause begins

[odd ember]

you could also try with 1/GetFrameRate() to get an approximation

of delta seconds, that is

[odd ember]

the blurry thing is a camera function, you can turn that off

I think it's a tickbox somewhere

I can't remember where

[runic phoenix]

Ok thanks I'll do some digging

[heavy peak]

Good morning, I had a quick question if someone could answer at all or provide even slight assistance on. We are having issues with our beam (an FX) going to the center of the crosshair in our third person game. We are able to spawn a line trace to get the point of impact we want it the beam to end up. The issue is the beam that is socketed to the hand is slightly off and when moving the character up and down it deviates even more.

Thanks in advance for any advice 🙂

[feral ice]

can i change at what level (z value) objects should get destroyed? Cuz i cant jump down before i get killed

[fierce stump]

So I've hade some issues with implementing a proper reload system with the function in the weapon master blueprint. Ideally I'd want to do something like GoldenEye where the weapon you're holding drops down off of the screen for the reload duration.

how do?

[blissful grail]

Yes. It's in the world settings tab

Kill Z is the setting

[feral ice]

yeah nice

[feral ice]

I assume this is first person

[fierce stump]

First-person, yeah

[feral ice]

Do you have a skeletal or is the gun just floating in the air?

like does you character have arms or is it just like this

@fierce stump

[fierce stump]

They have arms, but they're set to invisible

[feral ice]

you could just rotate the arm thats holding the gun

hmm im thinking of a way that doesnt require any animations

ill try and see if i come up with any solution

[fierce stump]

cause ideally I'd want the ammo to replenish after the gun goes back up

[feral ice]

https://youtu.be/a07CBMlxqWY This is the method im trying to implement @fierce stump

[grave relic]

Anyone that is able to help me? I spawn NPCs depending on a input int(currently 10) that runs a forloop for spawning. I pick a random pos on the nav mesh within a radius. But I never get them all to spawn, often around 1-3 are missing. I have the print string and it prints out "hello" on is not valid. Ive tested with print string and it runs through 10 times but some NPCs just get deleted.

[obtuse herald]

Set that to to adjust but always spawn

[grave relic]

My saviour! Thx

[lofty ravine]

Does anybody know how to do a live-editor in game like landscape editor

[hazy grail]

there is a plugin in the marketplace called "Interactive Dynamic Snow + Weather system - under 5 min Setup!" maybe something like that. I've also seen one so dynamic you can make caves and stuff in game, but don't know how to do it

[lofty ravine]

Yeah trying to mkae like users make there own landscape editing tools but idk how to do that

[hazy grail]

I think it takes custom C++ coding unless you can find someone that did it already

[obtuse herald]

landscape isn't really editable in runtime

[lofty ravine]

Frickkkk

Thanks though

[obtuse herald]

but you can create a flat landscape and materials to "fake it"

via heightmaps'n stuff

or you create your own mesh in runtime

[lofty ravine]

Is there a way they can import that stuff through run time

[obtuse herald]

yeah loading external textures in runtime works

[lofty ravine]

Hmmm ok is there a video on it

[obtuse herald]

I don't know

your second option is btw to create your own mesh in runtime

but that is a bit more advanced

[remote obsidian]

How would you take a rotator value, and add rotation to that value relative to itself?
I feel like I'm missing something obvious

Basically I get this rotation from the ImpactNormal of a lineTrace, then use LookAt to get the angle between the hit and the impact normal vector

I tried converting the normal to rotation but couldn't get consistent results

The problem with this current result is that I want the blue axis to be facing outwards from the hit, but if I use combine rotators I end up rotating every new angle by a world value rather than relative to itself

[obtuse herald]

to load an external texture you can use this node

[remote obsidian]

Problem solved - Make rot from Z was what I should have been using

[hollow sequoia]

Hi, I try to replace a make array ( with level references) by a Get all Actors Of class with tags ( target points are flagged ) then store them into and variable array to randomly spawn actors, the thirst way work well but the GetAllActors return an 'access none' did I miss something?

[odd ember]

actually never mind, you're checking for get all actors instead of checking if your array is valid. you should be checking your array that you set

[pliant sail]

Is there a way I can have the camera rotate around the character without the character always facing the same way or does it need a complete overhaul?

At the moment the character's facing direction is locked to the camera but I'm trying to have it so the character can face independently from the camera

[hazy grail]

maybe there are no "target point" BPs in the level?

or the array could be getting emptied later where we can't see

if you hook print string after targetpoint list hooked to with a do for each loop I'd like to see what it outputs

[dawn gazelle]

On your Camera Boom click the "Use Control Rotation" option

[pliant sail]

OK done that and it's rotating around the camera at the other end of the boom 😅

[steady night]

https://gyazo.com/a9289a0a110abdba618c77dec127e720

Hey guys, how do i check if "hud" is already showing ?

[earnest tangle]

Maybe store the widget you spawn into a variable, then you can check if it's valid or not

[dawn gazelle]

Sorry, on the actor itself, turn off "Use Controller Rotation Yaw".

[gentle urchin]

Or "Is Visible"

[steady night]

hm

[gentle urchin]

on the return pin of the create widget,

promote to variable

[steady night]

ah you can do like that

https://gyazo.com/349376187f52d9482ba9c152cdba541a

i did like this :/ ?

same same but different i suppose

[maiden wadi]

Checking the actual state of things creates less buggy games than storing other variables that make assumptions.

[steady night]

how do i remove widget from viewport ? or do i destroy the widget or what way is best ?

so boolean is better ?

[maiden wadi]

The boolean is the assumption.

[steady night]

oh

ty !

[hollow sequoia]

thanks I'll check this

[hollow sequoia]

I'll do that thank you, I was confident because the previous array creation worked

[steady night]

@gentle urchin hm i cant find the "is visible" condition is widget dosent appear in my list

oh had context sensetive on

got it

[maiden wadi]

You should see it even with that on if your pointer is correct. Messing with Unreal for over three years and I've turned context sensitive off less than a dozen times.

Do the codez.

You have to be missing a super somewhere then, or have the construction script move variable turned off. Which would still run it when finishing a move.

[steady night]

@maiden wadi hm ok so how could that be sometihng wrong the n?

[maiden wadi]

@stone linden Does this class inherit from a BP or C++ class?

[steady night]

BP

[maiden wadi]

Did you do this when you created your pointer? #blueprint message

[steady night]

YE

https://gyazo.com/153d83e8570b1a3acc282e715d5f833b

https://gyazo.com/1adc2452b0ad9637e35feb28db617b6d

its not working tho :/

[maiden wadi]

Cause you're backwards.

[pliant sail]

Lmao OK the camera is now working as intended so thank you....but now the actor doesn't move in the direction the camera is facing 😅

[maiden wadi]

If Visible set to Visible, if not visible then set to collapsed.

[surreal coyote]

Why does this just straight up fail to cast?
I set self visibility to false if it fails to cast the character on overlap. It's invisible instantly

[steady night]

oh

thanks 😛

works now

[maiden wadi]

It's kay. You can blame Squize, they did it too. 😄

[dawn gazelle]

You'll need to use the control rotation to drive which way the character moves.

[steady night]

yeah thats why i wonderd but x)

he did it in like 3 seconds so its fair game

[pliant sail]

Ah ok thank you :)

[dawn gazelle]

Casts fail if the object fed in is not, or does not inherit from, the defined class you're attempting to cast to.

[surreal coyote]

Explain

I placed a collision box around a car and want it to do something when the character moves into it

[gentle urchin]

Not sure what this means tbh

[gentle urchin]

well damn, i went to fast ! And got caught!

[dawn gazelle]

The Other Actor pin returns a basic actor reference which basically everything in your game world is. Let's say you have two different character classes, your BP_CharacterExample, and another BP_CharacterEnemy. Both of these classes inherit from just the base "Character" class.

If your BP_CharacterExample walks into that overlap, then the "Other Actor" pin will be returning a reference to your BP_CharacterExample character, just in a basic "Actor" reference instead. You then use your cast which is converting that Actor reference to a BP_CharacterExample reference, so the cast should succeed.

If the BP_CharacterEnemy walks into that overlap, then the "Other Actor" pin will be returning a reference to a BP_CharacterEnemy character, again, in a basic "Actor" reference instead. When attempting to cast, since this actor is not a BP_CharacterExample, and it does not inherit from BP_CharacterExample, the cast will fail.

[gentle urchin]

Ah, vaulting. Now it makes sense. My mind read Mantling..

[maiden wadi]

I took a quick glance through the C++ code. The singular thing I'm seeing that stops BP construction script is some setting called bDoUserConstructionScript. You messed with anything like that in project settings or whatever?

May also be some ini setting.

[gentle urchin]

I'd linetrace for it

[pliant sail]

Thank you @dawn gazelle it's working perfectly now! 👍👍👍

[surreal coyote]

I understand that. I only need to get this to work with the CharacterExample and only try it with that. How does it still fail to cast?

[gentle urchin]

Whenever you detect that you're going to vault (if ur detecting that already), i'd at the same time check the distance to vault for

[dawn gazelle]

As I just explained the cast would only fail if the thing you're feeding into it isn't a BP_CharacterExample object.

[gentle urchin]

If the question is how to detect vaultable obstacle in the first place then thats another thing ofcourse

[dawn gazelle]

So there could be other things overlapping that's causing it to fail.

[gentle urchin]

Linetrace for sure

When trying to vault, do a trace to figure out the depth needed to vault

[surreal coyote]

So I have to filter what it can overlap with?

[stable abyss]

Anybody can suggest a good blueprint tutorial or book. I'm technically a virgin in unreal engine 😫

[dawn gazelle]

Well, the cast somewhat does that already. It'll only ever proceed with the valid path if indeed the thing is a BP_CharacterExample.

[surreal coyote]

It just never does

But now it also doesn't fail anymore either

Now it's just doing nothing

[gentle urchin]

Simplest way to check whats going on ^ is to print its display name

the incoming actor

[surreal coyote]

Prints nothing

I think my collision box is broken

K, new collision box, cast fails again but prints nothing

Entire mesh turns invisible (failed cast)
Log prints nothing

[tawdry surge]

You realize print will never fire cuz it's white pint isn't connected to anything

[surreal coyote]

I'm tired

It overlaps with itself

Why does it overlap with the actor it's attached to

Doesn't make any sense..

[maiden wadi]

Makes perfect sense. It's a component. So it's going to check if it overlaps any other component. Actors have many different components. If you don't want your logic to run in that case, just check it. If Overlapped Component's Owner != OtherActor, then do code.

[surreal coyote]

Well it does overlap with the character now but it still doesn't do the logic after that

[gentle urchin]

Its not just rotated wrong?

[surreal coyote]

Nop

[gentle urchin]

And it contains text?

[surreal coyote]

The text is Enter

[gentle urchin]

Also, i think this would be better as a on screen widget instead

Belonging to the character

Allowing interactable objects to send their location and interaction text

[surreal coyote]

The cast doesn't fail. I connected it to the mesh invisibility on cast fail and the mesh turns invisible when I overlap with the hitbox

[gentle urchin]

Mesh turns invisible?

[surreal coyote]

My "debug"

[gentle urchin]

So the cast succeeds

[surreal coyote]

So with this it does not turn invisible but the text is also not visible

[gentle urchin]

Eject from the controller while playing

Check the text component

Both its visibility and text

[surreal coyote]

Text is "Enter", hidden by default

[gentle urchin]

Hidden in game.......

Is not the same as visible

As you can see, they are seperate

Hidden in game overrides visibility

[surreal coyote]

I swear I shouldn't do this stuff at 2am

My apologies

I literally did it for my emergency lights before..

Thank you

[broken wadi]

What's the fastest way to check if a custom event from a blueprint is used in any other blueprints? I know the reference viewer can help determine if anything from that blueprint is being used by another blueprint but I'm looking for a specific event. So far I just keep opening up blueprints and doing a CTRL + F to search for the event.

[hazy grail]

I'm trying to figure out how to enable mods in my Unreal game. Anyone know an easy way to enable that?

[hazy grail]

print string

[odd ember]

probably not through blueprints. have you googled it?

[hazy grail]

I tried. Very little came up. I found this thing called mod.io, but if I could do it easier that would be better. All I want is for them to be able to add their mesh they loaded up with Unreal already.

I was thinking maybe a simple open the game file up and add their uasset might work

, but IDK

[empty bison]

any linetrace specialists in here ? my brain is not working anymore, cant calculate, im hanging 😄

[odd ember]

well I just googled it and there's a bunch

https://www.tomlooman.com/unreal-engine-mod-support-example/

tom looman is reliable too

[hazy grail]

Thank you. I'll look into that. Didn't pop up for my google. that search is so custom for each person now a days.

[broken wadi]

Well I can print something like "this event was called from this blueprint" whenever it fires, but I'm trying to find in my blueprints exactly WHERE that particular custom event was called so I know it can be safely deleted or not.

The reference viewer helps to find if blueprint A is being used inside of blueprint B, but I'm only interested if a particular custom event from blueprint A is being used.

[hazy grail]

You can put a print string anywhere you want at any event. It will show exactly if a part is being executed. Further I would not keep print string around all over the place. Use for a test. After tested remove the print string.

[broken wadi]

That isn't really what I'm after, my use case is more about refactoring code or deleting something.

[obtuse herald]

where is the problem?

[broken wadi]

Can I safely remove this custom event? I forgot if its used elsewhere.

[hazy grail]

You are trying to on the fly remove events?

during runtime?

[broken wadi]

I know that this custom event isn't ever being called within the blueprint I made it in, but I can't remember if another blueprint is using it or not.

Then its like that problem over and over again lol

[obtuse herald]

just check with the reference finder

or whatever it is called

lemme open a project

[broken wadi]

Yes I have been using the reference viewer, but that only helps determine if blueprint abc has any reference to blueprint xyz, but I'm only looking for a particular custom event. So I have to open each one and do a CTRL + F to search for it.... rather tedious.

Because blueprint abc is being called by say like 20 other blueprints

[obtuse herald]

right click on the node and click on "Find References"

[broken wadi]

That's just like pressing CTRL + F to search, it only scans within the current blueprint.

[obtuse herald]

and then click on the binoscluar on the right-hand side

[broken wadi]

ahhhh bingo!

That's what I was missing the binoculars

thanks

[obtuse herald]

you're welcome

[small halo]

this is my ragdoll code as of now
https://gyazo.com/3cd72ca2ea330e79c27ab6935842bb43
At the moment, my ai runs to me and when i send of a blast out of my character to kill the enemy, the ai will die and fly towards me as its simulating physics (ai was initially running towards me) however, i want the same effects as a ragdoll but i want the ai to fly away from me when i use the blast as it makes sense

is there any way of doing this

[obtuse herald]

apply a radial force to your enemys skeletal mesh

[obtuse herald]

it's a node

[small halo]

would this be in the ragdoll event?

[obtuse herald]

that's your decision at the end, but I would put it there where you also do the blast

[small halo]

and the target being my AI's mesh?

also before or after where i call the ragdoll event

[trim marsh]

Yo, guys , someone know a way to clean the child box one by one? , i've a horizontal box , this function clear all

[obtuse herald]

after

[obtuse herald]

if you want to apply it to every physics object and not only to your enemys sk, you can do it like this:

[small halo]

yeah i added it into the for loop

but dont u need the mesh for the target?

[obtuse herald]

you only need a 'primitive component' (a mesh is a primitive component)

[small halo]

origin is the players location as thats where i want the blast to come out from right?

[obtuse herald]

yes

[small halo]

thanks it worked @obtuse herald

[trim marsh]

lov'u, thx 💪🏽

[wicked osprey]

Guys, what should I do if I created a sound cue variable in the parent class, but I don't need this sound in only one child class? Is there any way to close it for this child class?

[obtuse herald]

just don't use it

or split your hierarchy tree into a class with the sound and a class without the sound

[surreal coyote]

Is there an easy way to always get a location to the left of a movable actor?

[wicked osprey]

And why blueprint haven't protected variables? (

[obtuse herald]

interestingly functions do have that functionality

[obtuse herald]

you mean a direction vector?

[keen wedge]

Sanity Check Please...

I'm experiencing some weird behaviour in a function, its probably something else, but I just wanted to check...

If I set a local variable in a function, and that function is executed many times, in quick succession (from input event), does each call to that function use a "unique" instance of that local variable for each function call? This is my expected behaviour, and how I thought these things worked in general... but as I say, some odd behaviour as if the local variable has changed by the time its almost at the end of the function - just wondered if a subseqent (or many subsequent) calls to that function could be over writing that value...

[surreal coyote]

When I detach from my vehicle I'd like to always go to the left of it

[obtuse herald]

yes, local variable is unique for every function call

[keen wedge]

Thank you... thats what I thought etc but very odd behaviour... will keep looking for other causes... thx 🙂

[surreal coyote]

I actually just pulled a big brain I think

I have a collision box on the left of the vehicle to check if I can enter it or not

[obtuse herald]

scene component?

[obtuse herald]

yeah you can also just add an empty scene component

probably easier to manage anyways

[surreal coyote]

I love it when my brain works

[obtuse herald]

hahaha

who doesn't

[surreal coyote]

Well it works when the car is on the road. When it's on a sidewalk and I get out, it launches up in the air like a rocket

[obtuse herald]

yeah probably because it teleports you inside the sidewalk

[surreal coyote]

Even with Z +50

Plus my character is fine, only the car

[obtuse herald]

wait the car gets launched?

[surreal coyote]

Yep

[obtuse herald]

well that's another problem and not releated to your set location node

[surreal coyote]

The car is way too easy to move around anyway. Can push it with my character

Guess I'll have to increase its mass?

[obtuse herald]

yeah

[surreal coyote]

Even at mass scale 50 it gets launched

[obtuse herald]

why not just set the mass to a realistic value?

[odd ember]

sounds like a #legacy-physics problem

[restive token]

when a user alt-tabs away and comes back, the widget loses focus
is there a simple way to refocus if they come back? is there an event for coming back from alt-tab?

[quick marsh]

I'm making a damage system, when the player touches this basic enemy blueprint it should take some of their health. Is there a way I can get it so it only takes the health of the player if it overlays with the players capsule component?

at the moment the player has a collision box in front of them for the sword and I want the enemy to ignore that box

[odd ember]

I think there is in CPP, but not sure about BP

[tawdry surge]

If you select the capsule component it should have an on component overlap begin event at the bottom of the details panel

[quick marsh]

but this is in the enemy blueprint

would it just be easier to do it in the player blueprint?

[tawdry surge]

Oh. Set the box to ignore pawns

[quick marsh]

alright, that works, is that going to cause any problems if I need that box to interact with enemy characters though?

[charred berry]

was baseflattennormalmap texture for BP, changed to T_flat_Normal ? ( think so as former isn't showing up under material expression texture base)

[odd ember]

I think you meant to ask that in #graphics perhaps? @charred berry

[charred berry]

I'm using BP's so I thought it was here, ok np

[odd ember]

are you referring to the material graph?

[tawdry surge]

Yeah. You're telling it to ignore them..
What is the point of the box?

[quick marsh]

the area the player will be able to slash their sword

I'm sorry if these are dumb questions, I'm really new to unreal

[sand radish]

Hello everyone, I m new to UE4; I have a level with multiple player starts; I have figured out how to travel back and forth from the levels and start at the desired player start. But at the first startup, it will jump randomly to one of the player's starts; how do I set up the default player start on a level with multiple players starts?

[tawdry surge]

@quick marsh I don't understand. Are you using it for damaging things when you swing the sword?

[quick marsh]

yes

[odd ember]

can you show the pickup code?

[sand radish]

Lets call the level with the multiple play starts as main, and the other as 2nd, this is code on the level blueprint from my 2nd into main

ugh sorry ue4 crashe

this is my code on my gamemode

[quick marsh]

the player has a capsule component that when hit should lower the players heath. I've put a box collision for when the sword animation will be played and damage enemies but the way the code is at the moment its considering the player as a whole so when the enemy overlaps with anything, including the box, the player takes damage

is there a better way to work with weapons then?

I might just ask my teacher next time im in class

[trim matrix]

dumb questions but how do you make something "happen" without using event tick?

I'm trying to generate a sine wave but I don't want to use delta seconds lol

I want to have some node "work" every say, x seconds

[zealous fog]

Timers

[odd ember]

a sine wave is a perfect use case for a timeline component

[main lake]

I'm using the Example Content by Epic Games to learn all the stuff through those explained levels but there are alot of them, does anyone know if it's possible to play the first one and when you're done you go through a teleporter and it will move you to the next level so you don't have to stop the play mode and launch another level each time?

[trim matrix]

thanks not that, still not sure how to generate a sine wave that sweeps from -180 to 180

[odd ember]

have you tried timelines?

[trim matrix]

I'm looking at it now for the first time

I'm assuming I want a float track to set my function right?

y = sin(x)

oh nvm I got it that's insanely cool

[odd ember]

yeah glad you got it figured out

the float track generally you can use with alpha values to lerp anything between two states fluidly

doors etc. as well

[trim matrix]

The only thing is that I plotted the points of a sine wave by hand which is easy enough (just 4 points really), but how do you actually input a function in it?

[odd ember]

hmm I'm not sure you can. perhaps if you supply a curve asset separately you can do that, but I'm not too sure

[amber kindle]

Does anyone know how to make a button run an event to choose a random map (level) ? Im very new to this.

[odd ember]

like a menu button?

[amber kindle]

Yes

[odd ember]

that would be a widget, I'm sure if you search for button widget you can find a tutorial. for the actual functionality, I'd have a table or array of level paths that get picked at random into an OpenLevel node

[amber kindle]

Tu

Ty

Ill see if i can find a tutorial

[jolly inlet]

Trying to get a blend blueprint going with the megascans. How should i go about that here

[tawdry surge]

@quick marsh Why not just have the sword trigger a hit event on the enemy when it hits the enemy?

[odd ember]

this is the material graph, not blueprints. #graphics

[trim matrix]

heyy i've got a question, is there a way to disable triggers? i've been trying to find a way to disable it, but nothing works, is there a special node or something else that i'm missing? and yea i tried to spawn the actor in and it he didn't open the door because it needs to specify which door he should trigger to open

[umbral dirge]

"Choose Player Start" executes before "Begin PLay". Is it okay behaviour? Cause im want to give first player first spawn spot and for the second player second spawn spot etc.

[odd ember]

you cannot ensure the correct order of beginplay

[trim matrix]

wrong chat?

[trim marsh]

guys , how can get a unique random value?

[umbral dirge]

Its all in blueprint.

[trim matrix]

talking about the guy promoting his game

lol

sorry should've specified

[odd ember]

use a foreach loop?

or do you just want 1 thing to have random value?

if so just use the random node

with set visibility

done

[trim marsh]

this works, the array value need to be called every loop , but the random dont pick unic values, need a method to dissapear the random value from the array , when its called

like this

[magic summit]

hello is it possible to have sort of boolean or something that switches true or false upon development or shipping build?

for example I would like to have login bypass in dev build and automatically remove it in shipping build

[untold mist]

@magic summit "is packaged for distribution" I think thats what you're looking for

[magic summit]

thanks

its exactly what I was looking for

[untold mist]

Don't know if this is the "correct" way to do it but this is how do it

[trim marsh]

thx so much

[hard scarab]

How best could I setup a timer to track the time in between a players actions for a minigame?

[odd ember]

get game time when the first action happens, compare it when the next action happens

[hard scarab]

Thanks!

[sharp rapids]

gonna have to redo the whole inventory system 😫

a different question, Do empty arrays occupy memory?

[jaunty summit]

No

[faint pasture]

Even if they did, don't worry about it.

How do I get around this message? I have VS 2021 installed.

Hi everybody! is there any reason as to why i can't Override OnRepNotify on BP? is this intentional or a bug?
As a workaround i'm creating a new Method and calling that one OnRep, so i can override that other method for my changes, but it's kind of annoying
(I'm posting this one there and on MP because it also involves bp, not spam)

I have a chunk system and i'm trying to have each chunk have it's own random seed do you guys think this is the correct way to approach that?

on animation menu , can set sound notifies , and you call every time that this is played

Please, can someone help me

[obtuse herald]

It's not the best way but it should work

[merry moth]

I'm having the issue of the random stream not really being random...

I think i'm not really under standing how to use it. I'm used to seeded randomness acting different i guess? This just ends up giving alot of the same numbers

[obtuse herald]

Ahh, yeah random stream is not that good especially at low values

[merry moth]

Is there a better alternative to seeded randomness in ue4/ue5

[obtuse herald]

Just change the 10000 to 1000000000 and see if it gives you better results

[merry moth]

I think the issue stems from my chunk system allowing -1,1 and so on

It will at the end of the day be the same if it's 1,-1

[obtuse herald]

Should be fine

[obtuse herald]

How do you call your random functions?

[merry moth]

Random bool from stream and other functions

[obtuse herald]

Show a pic

[merry moth]

https://files.catbox.moe/w384w1.png

[obtuse herald]

Ok

[trim matrix]

the people on this server are very rude, you didn't even try to help me

[obtuse herald]

So you have a seed variable that you set once yeah?

[obtuse herald]

Never really worked with anim notifys

[trim matrix]

this is not anim notifys

[merry moth]

Yeah

[obtuse herald]

Because if you always retrieve a new random stream with the same initial seed it will always give you the same value

[trim matrix]

You lazybones didn't even read my messages, fuck you, I don't want your help anymore

[merry moth]

Bro chill

[obtuse herald]

Ok, but don't use equal on float

[obtuse herald]

Also that's a lot of nodes for essentially one random bool xd

[merry moth]

Yeah it was just a test to get something

[obtuse herald]

Did you try upping the limit in your 'get seed' function?

[merry moth]

Yeah it didn't work @_@

Chunks 1,-1 and -1,1 are still coming out the same

[obtuse herald]

Oh yeah actually that makes sense

[merry moth]

Is there a good way to generate a seed for two integers?

[obtuse herald]

You probably want to do some math magic dividing stuff and such to generate your seed value

(X10) * (Y/2.5) + (WorldSeedX/Y)

[obtuse herald]

Try that formula

[wicked osprey]

Hello guys, why blueprint haven't protected variables and how to get around it? If I set private variable I can't change it in child class, and if I set public class I'm violating OOP rules(in particular encapsulation)

[obtuse herald]

Use naming convention

[sharp rapids]

Is there any way to set the 'Outer object' of a 'Object' reference to null?

I have a BP derived from the 'Object' class

I'm using the 'Construct Object from class' node to create an instance of it at Runtime

When it's no longer needed, I'm setting the reference to null
