better learn cpp then 😄

I know CPP.. I'm writing a crafting system for a friend, and he only knows BP
flat raft
I just look at the CPP Api. I just got lazy lol

yeah putting helpful stuff in blueprint function libraries is a good practice
unless you need something that works with generic arrays or DataTables, then it's hell to work with 😄

Yea, generic
I created a unreal share git

Hiho i have a question again 🥺
In the tutorial im watching he is creating every skill in the Character_BP, so the Mage have all mage skills, the Tank have all Tank skills and so on. My Idea is to create 4 different BaseBP´s and link this base BP to the character how should lern this skills.
Ist that way better für the performence?
I have skills like Fireball and 3 different Mages can cast that spell. Its easyer to link the Skill_BP to an Character than create the same skill 2 or 3 times??
if i have an different skill_BP i can use that skill for enemies too

sonic pine
ok a parent skill like a base skill to link to each char how should lern that skill?
trim matrix
explain what u trying to do.
u want to make 1 spell and every character should be able to use that spell ?
sonic pine
Ok i want to have 4 different Chars you can choose. If you will take the Elemental Mage you can some los ice, electric, fire and wind skills, the Dark Mage can different Fire and darkness skills.
So Small Fireball is a skill that 2 different mages can leran, the same problem i have by the melee champs some attack are the same
so my question is if i make a Skill_BP and link that BP to Darkmage, Elemental Mage and different monsters, i dont need to rebuild the skill every time. Im buildig the skill 1 times and can link it to every champ, Mob, Boss i want
For example the "hit", every champ, boss, mob ist hitting between the spacial spells, so i can create one hit for all and only link the hit_BP to the different Chars
the different power of the hit is coming from the damage poits of the Char who is hitting.
For example
Skill: hit = 5 DMG + Char 1 = 20 DMG =25DMG/hit
Skill: hit = 5 DMG + Char 2 = 25 DMG =30DMG/hit
Skill: hit = 5 DMG + Boss 1 = 100 DMG =105DMG/hit
so i give every monster/Char/boss only the special attacks and the base attacks flike small fireball or hit i need to config only onetimes and not für every char/mob/boss
Im asking because of changes. If i have only one hit_BP i can change the hitpower from 5 to 6 without chaning every character
frozen dune
I understood what you need and will suggest two approaches depending on the scale of your game
if you have few skills for each character/boss, create a basic class as an Actor Component that contains all basic functionality for magic such as damage, range and so on.
Then create a single BP for each skill and then tie it to each character/boss as needed. Each spell type will be a single BP and can be reused for as many chars as needed.
you can make an event or function call to automatically update the skill stats based on the component owner
If you have the need for many more skills, I would make another component that manages if a character can or not have access to that particular skill at that moment.
wind atlas
good day, I'm just starting to build the base for my game, I plan to have physics based vehicles, I'm not sure if I should use a pawn as my base class or a character as my base class, that then will have children which can be different types of vehicles.
I'm a little lost on how to get a solid foundation with correct inheritance heirarchy. I'm not sure if I should make a character that can move to and then possess vehicles, I don't necessarily need technical help but more general advice.
I'm currently following the "Twin Stick Shooter with Blueprint" course on the epic games website
sonic pine
@frozen dune Thanks 😉
teal burrow
That's kinda how I have my systems too
It's been decent so far, but spawning an actor for something that doesn't move doesn't feel very optimized
Though the optimizations since 4.25 helped with that a lot
sonic pine
Yeah the "updates"/Changes are global and not for each char/boss and so on. the testing time is lower, if 1 char is using the spell, and the other cahr say no, it can only be a mistake bei linking, because the spell is running on all other chars ^^
and the game would be smaler, i havnt 100 times the same skill_BP
teal burrow
Even then, it's not that expensive, at least depending on your game's scale
sonic pine
and time ^^
teal burrow
For me, I fit 5 spells and whatever other functionality they have (projectiles, status effects, etc) in 10 MB of BP
And that's before packaging
sonic pine
nice ^^
teal burrow
I wanted to release my game and its framework soon but 4.26 has a bunch of features I'd like to use
It has exactly that and makes developing a game a breeze
sonic pine
maybe you can create a way to fix it or to do thesame without the components you normally need?
teal burrow
I've already done that
sonic pine
ok nice
teal burrow
Though I focus on customizability and mod support
flat raft
@sonic pine You need to use inheritance, if you're not already.
It's the best way to pass abilities to child classes
sonic pine
Thanks i fothot this ^^
still sigil
Yo, so does anyone know how to go about doing a camera like this? You fall down a bottomless pit, and the camera lags behind in the air, but still pans down to show the player falling to their doom? 😛
teal burrow
Spawn a new camera that auto-possesses once the character falls down
still sigil
Interesting. I think I'll give that a try. I haven't actually started on this yet, but it's something I know I'm gonna incorporate into my game eventually, so I wanted to get some ideas going on how to approach it.
teal burrow
Make your base mechanics first
This camera can be easily done if you have literally nothing else to do
still sigil
Especially since trying to tell the player camera to move in a specific way seems to be alot more difficult than it really should be, when it's not just the default player input movement. (I've been using the default Third Person camera this whole time, with very little alterations.) So I wanted to get a head start on that.
teal burrow
Default movement is fine until you get into anticheat
Also Raikun if you're still here, I just checked and turns out a full character functionality fits in 2.5 MB for 5 skills and a passive
still sigil
That will require some programming/blueprinting work on your end. "Flying" basically just disables gravity for the character, and suspends them in the air.
If they are actually IN the air when it's activated that is. You won't really notice the effects if you have it activate while on the ground.
hearty gazelle
What im trying to do is launch the character into the air and then suspend them in zero gravity
because the game takes place in space
still sigil
Then I guess do like a "Launch Character" node? Set how high you wanna launch them, then activate the "Flying" movement mode at whatever moment you wanna keep them in the air.
hearty gazelle
Yeah and then when im in the air, do I have to use forces to move my character?
still sigil
Or you don't even have to change the movement mode at all. You can just tell it to change the gravity to a certain point.
Most likely. Any space movement you'll have to implement yourself. How to do it, I can't really tell you, cause I don't know how you want the movement of your game to feel. 😛
That's all on you to decide.
hearty gazelle
The thing is is that when I change gravity scale to 0, it just keeps floating up.
Is there a way to sort of make gravity scale 0 but control movement
still sigil
Are you wanting like moon physics or something?
hearty gazelle
Like an astronaut floating in space.
but like
you get launched to a specific point
then your floating in space then you can make the character move in the direction u want and also float up if you press space
still sigil
Okay well, floating up can probably be achieved by using a "Move Up" node. And vice versa if you want a way to descend aswell.
As for forward and back movement, I'm not really sure. I've not tackled any sort of flying movement before, so someone with more knowledge than I do will have to help you with that. 😛

Hello! does anyone know how to get the parent class of an asset in blueprints or through the unreal python api? I have already tried using "Get Tag Values" to get the parent class which only gives me a string, I need the actual parent class object

@coral fossil don't know if there is a specific node, but in your parent class, you can make a variable of type class, and store the class of the parent. you can then access that from the child.

coral fossil
@flat raft I still don't get it, I can only get the parent class as a string, and how can I store it then as a class when its only a string?
flat raft
GetClass > Promote to Variable
coral fossil
but GetClass gives me only the blueprint class, I want the parent class. so say, I have a character, GetClass only give me "Blueprint", but I want the parent class: "Character"
flat raft
I don't understand
If you have a class called MyCharacter, and you create a Child Class called MyChildCharacter, using GetClass inside of MyChildCharacter will give you the class MyChildCharacter. If you use GetClass in MyCharacter, you'll get MyCharacter.
If I understood, you want to get the Parent Class of MyChildCharcter, which is MyCharaxter?
@coral fossil
coral fossil
when you say, using GetClass inside of MyChildCharacter what do you mean? I'm using AssetData -> GetClass -> promote to variable, then I get "Blueprint"
@flat raft
or are you using c++ for this?
dusk flame
I'm pretty sure n that case you can do GetParent -> GetClass.
Anyways, can anybody suggest a method for providing a default value, in the case of IsValid failing?
I have a class like GetSubSystem->GetDog->GetName if GetDog is not valid, I just want to default the entire output to some OTHER string like Rover or NoNameFound
trim matrix
spawning and deleting a lot of ui widgets
dusk flame
But atm I haven't found a way to do it, using either Select nodes or Branch nodes, since the GetName isn't an exec, its getting called no matter how I try to branch it.
covert stirrup
How do I tell a scene capture to stop recording in BP? I can't see any relevant variables
glacial eagle
If "Capture Every Frame" is checked they will capture constantly
They don't "record" as such
covert stirrup
yea sorry bad use of language on my part. I think I have a bad scene, I thought the framerate was due to the scene capture, but removing it all the scene is lagging heavily and it really shouldn't (basically empty)
so think I am bugged or the latest driver for my GPU is fucked
glacial eagle
Well the scene capture is always going to be like having a second monitor the size of the render target on screen
They are far from cheap
You can disable "capture every frame" and manually call the "capture scene deferred" function if you want
Not sure if those are the exact node names in BP but something like that
But don't forget how expensive it might be, also depends on the size of the render target it's capturing into
covert stirrup
nah I know that, but it's not in my scene with nothing else and I am below 120fps, something isn't right
I got sent on a red herring chase thinking my code was wrong but it's actually working just fine xD
I had SSGI enabled, which didn't help was testing to see the differences but it does add frame overhead
covert stirrup
it's really weird -- When I simulate, its telling me it wants to build 6 captures, but I have nothing in my scene that creates this. everything has been removed from the scene
Solved, it's the new dynamic sky - In the level blueprint it is capturing on tick
glacial eagle
ewww
uncut sonnet
I'm fairly new to Blueprint, and trying to work this out for a little bit now.
I have a blueprint with an arrow, and I want the arrows print string output value to be 0-1 for the full 360 degrees of the arrows rotation.
I'm using Get Forward Vector, and by using a dot product and doing a constant Bias scale, I've been able to essentially turn 0-180 into 0-1 but after it hits the 180 it starts going into minus numbers.
I'm sure there is a much more simple solution than I'm thinking of here.
sonic pine
Hiho. In my Character_BP i have all all Variables i need für my skills, now im Trying to outsouce the skills into a seperated BP to include the finished Skill. But This part will not work corectly.
I try to fix that like this
My idea was Cast to Character_BP will import the Health and mana Variables but it doesnt ^^
Someone have any idea how to fix that?
covert stirrup
@glacial eagle tell me about it xD it's like that by default 🤢
maiden wadi
@uncut sonnet All you need to do is convert the usual -180 to 180 into a 360 value. Then do that value divided by 360. 0 will be 0, 360 will be 1.
uncut sonnet
This is how its looking right now.
maiden wadi
I'm not sure that's what you're after. Do you know what the DotProduct is?
uncut sonnet
Oh! Theres a Map Range Unclamped node, this could be what I'm searching for, or, it could be entirely different.
The dot product is outputting 1-0 for the first 45 degrees of the rotation.
maiden wadi
DotProduct is a measure of how similar two pointing vectors are to one another. It'll be one if two vectors face the exact same direction 0 if they are facing tangent or 90 degrees of each other, and -1 if they're facing opposite directions.
Which rotator does your arrow move on? Like turning left and right in a typical shooter, the Yaw?
uncut sonnet
I'm looking down the Y axis and rotating it in the Y axis.
maiden wadi
So pitch in a typical rotator? IE, looking up and down in a typical shooter game.
uncut sonnet
Yes I believe that'd be correct. Sorry, had to convert that in my head for a moment.
maiden wadi
Try something like this. Could be what you're after I think.
Gives me 0.75 if I look straight down, and 0.25 straight up. 0 looking at horizon level.
uncut sonnet
Thankyou, I'll give it a go.
swift sphinx
i've seen more and more use of this "hard mapped keys" style! is this a better way of making a character BP? :S why not use the default UE4 that comes withe ThirdPersonBP?

I just use it for testing and quick implementation. No point wasting time mapping keys for testing. If I plan on doing something serious that I know is going to stay, I'll map a project keybind for it.
uncut sonnet
My find lok at rotation looks nothing like yours.
Possibly because I'm on UE 4.20
maiden wadi
Show me? I thought that was an ancient function.
maiden wadi
Oh. No, it's the same. Just right click on the purple pin when it's not connected and Split Struct Pin.
uncut sonnet
Oh... god that was dumb sorry.
covert stirrup
Is it possible to scale the 'Size X' of a render target at run time?
It works in construction script, but the same code doesn't function in the event graph
maiden wadi
Stuff like Rotators and Vectors are Structs, and you can do that with any struct pins in BP.
uncut sonnet
It's not quite right
180 gives me a value of 1
270 gives me a value of 0.75
Facing left on the horizon is 0 and looking straight up is 0.25 as you mentioned.
straight down gives me 0.75 but 180 gives me 1, wheras it should give 0.5
maiden wadi
Yeah, I just realized my error. I wasn't considering Unreal's FPS perspective, where pitch facing one way is the same pitch facing the other way.
uncut sonnet
Yeah, this is what I've been running into the whole time too.

@swift pewter save your emitter as a variable right after it is spawned, then access that variable to make changes to it or destroy it.
olive ferry
Hey! Can someone help me with the following problem. I need to deproject screen space location to world space. I use the node Deproject Screen to World. But it has some offset due to the fact it doesn't consider camera settings. How to get exactly matching point in a 3d space to identify an actor under this 2D coordinates? Please, don't refer to some topics on the Internet. I have already learned them and still didn't get it working
swift pewter
How can I destroy it, doing it that way @proud hull
proud hull
It won't work your way because it loses its reference over time. Spawn nodes will cache its results, but not permanently unless you tell it to (like store in a variable). If your destroy node was within the same execution path, it would work, but it is part of a separate event that may be called seconds, minute, hours, days after it is initially created.
The output pin of your spawn emitter node, right click that pin and "promote to variable"
Then right-click anywhere and type in "get" plus the name of the new variable. Then crag from the get node to the target of the destroy node.
Or instead of typing, you can drag the new variable from the "variables" section on the left, to your graph, and choose "get".
Your isValid node and destroy node should be connected directly to the new variable.
Yeah, you will want it empty so that the isValid node fails when you have no emitter spawned.
fair magnet
Hey everone... I'm trying to use a Switch on Enum for my Defense Calculation... but how do I set an Enum Var depending on the damage type ?
covert stirrup
hey @fair magnet where does your damage type get set?
covert stirrup
with that current setup you are manually choosing the damage type in the blueprint, if you create a variable and put it into where it says physical damage, you will have the options you can expose in the editor and select which type you want an object to give
fair magnet
but what if an enemy can use magical skills aand physical skills ?
covert stirrup
Then an enum is probably not the best way to go about it
fair magnet
what's better then ? o:
covert stirrup
well, your damage is going to be either a float or an integer
in your BP you'd set that particular float to be magic or physical, which then does the calculation you want for that particular damage
fair magnet
Okay so far I've understood... but how do I find out which damage it is ?
covert stirrup
lets back up
fair magnet
I mean.. yes there are these damage types
covert stirrup
Why does magic and physical need to be different?
whats the ultimate goal to seperate them
fair magnet
Because magic casters have different weaknesses than knights have
physical stuff would be more meele stuff
while magic stuf is more ranged
like fireballs
fair magnet
yes
covert stirrup
So all you need is a tag to define the damage source
It entirely depends on how all your damage outputs are setup if its one master class or seperate but if you want to do it the enum way, have the blueprint specify which type you want it to be for the type
and as you run it through "physical" that's where your debuffs are, if they apply
but you already have that setup so not sure where the issue is, maybe how you have your damage BP's setup?
covert stirrup
Was doing some awesome drawing how I envisage it
so you have a BP for melee damage and Ranged damage with their enum set to the desired value and that goes the Stat System as a custom event, with the follow through line. I put a branch but I meant Switch on Enum so you can select based on the desired Enum outcome line

Hiho someone know how to create a skill without the main Character?
This is the BP in the MainCharacter_BP with all Variables, and i want to create this Skill in an seperate BP to include it into the chars who should usw that skill

@sonic pine Are you saying that you want the main character, and an NPC to be able to use the same ability, with the same mana checks and the like?
sonic pine
No the main character and an NPC or other characters should be able to use the same skill but every character need his own mana request

so i try to create Heal_BP with the funktion Heal, the mana costs, the cooldown and this BP i want to include to the MainChar_BP, NPC_BP so the chars can youse the skill but i dont need to create the skill in very character. 1 PB linked to 10 Chars for example ^^
Can I ask why the NPCs or others need a different check than the main character?
@maiden wadi If the Main char have 50/100 Mana and an other char/mob have 0/100 Mana the Main can heal and the Mob cant heal. If the Mana request is in the skill i give the mana to the skill an not to the char
its ddifficult to describe ^^

Unfortunately, the issue here is that you shouldn't really create a full actor just for a mana check. You should write the check in the character class, then spawn the skill after. I mean you 'can'. But you shouldn't. Use what's already in the world to do simple checks instead of allocating memory and resources to spawning a full actor that might not even get used just to destroy it when it can't be used.
hollow drift
Hi, what kind of other events could i use to trigger the event when my object is already overlapping on gamestart. since when it does so it does not register "begin overlap" yet.
maiden wadi
@hollow drift There's a checkbox somewhere, I can find it in a minute if you can't, but it causes overlaps to be checked on component or actor creation at beginplay or something.

still unable to destroy this compenent. should i be making a interface here to interact with the two blueprints? its casting the true bool but not destroying the component of itself.

Not to the box itself, check that on the Actor that has the box.

It'll generate the box's overlap event too.

@maiden wadi I want to have 2 different Blueprints
Blueprint 1 Character 1 Firemage
All Character Informatios like animations, camera, moving and character stats (Health and Mana)
Blueprint 1.2 Character 1 Darkmage
All Character Informatios like animations, camera, moving and character stats (Health and Mana)
Both mages have a Base spell for example Fireball
Blueprint 2 Skill Fireball
Skill Informations, Skill Damage, mana costs, gravity, cooldown, when the skill can be casted and so on
Now i want to include the Fireball into the Firemage and the Darkmage, without copying and double Variables.
I think i can link the skill with the Cast to Character command so both mages can use the skill without the skill have to be in there BP as code/BP.
The positiv effect of that is: If im changing the skill Colision or Damage i have to edit the Fireball_BP and not all characters with this skill.
My problem is i cant controll the Mana of the characters out of the skill_BP and i cant take the mana from the character out of the Skill_BP
hollow drift
@maiden wadi sorry to bother y again but i cant find a way to connect this:
Also the checkbox is not present anymore as like you have mentioned before:
https://answers.unrealengine.com/questions/980963/how-to-trigger-an-event-when-streaming-level-loads.html
This checkbox is not there, also not on actor
maiden wadi
@hollow drift You have a BP like this, with a box, and the overlap event for the box like so. In the same Blueprint, click on class defaults.
And just change the checkbox in the bottom right.
maiden wadi
Not the box. The actor itself. Look at the second screenshot I posted.
@sonic pine Do your Darkmage, and Firemage share the same base class?
hollow drift
I am confused^^
maiden wadi
hollow drift
ahh
damn
it is already set
but doesnt work rip
I read somewhere there is a bug with it?
maiden wadi
That's odd. If I place two of those in the world overlapping each other, they'll print each other after that's checked.
hollow drift
it updates for me only when i move componend
thats about my structure
i check if i overlap with a "puzzleblock"
sonic pine
Not the box. The actor itself. Look at the second screenshot I posted.
@maiden wadi Yes ^^
maiden wadi
@hollow drift Trying to replicate the issue. Are these actors spawned in code at the same spot, or are they placed in a level manually?
hollow drift
placed manually
so to speak
i generated "pirate_pawn" which inherits the code above inside of puzzleblockgrid (from ue4 default starting template)
just with some coords
but guess can call it "manually"
y wanna have a look into the code with screensharing?
it s a bit complex
maiden wadi
I was just asking, because the only way I can get the overlap to not fire, is if I create two actors at the same time on top of each other. If I input a small delay between the spawns, the overlap fires again. Which leads me to believe that you can't generate overlap events from actors spawned in the same moment.
hollow drift
ah i see
thats the bug perhaps
leme try
yes
it seems it works from "top down" and cannot load everything at once
this is baad..
or wait, ill generate it at the end
o man, still does not work perfect
i need to set delay even higher then 0,2 else my below tiles are not updated lol
o man, this will make issues for the future ^^

@trim matrix Literally everything in the game is destroyed when you load a different map except for the GameInstance. To retain those values, you will either need to rely on the GameInstance Or learn how to use SaveGames to accomplish this. Savegames are often the better gameplay choice, but some people do rely on GameInstance.

Hey ho! I'm packaging my project and I've set it up in the player pawn that you can change levels if you hit the spacebar. But the packaged project doesnt seem to be able to find the 2nd level. (as it tries to go there but reloads current). I've added it in the "Packaging" dropdown thingy in the Project Settings. Anyone knows if you need to do more stuff for it to work 😮 ?

I have a customer player controler bp, changed my default gamemode and added my player controler but i still cannot get out a result when left mouse is pressed. Did i missed something?
In mouse interface i also enabled click events and show mouse cursor but this did not help either
As also adding click event keys
frank lantern
Hi! Hope someone can help me here :-))
I am trying to have a logo overlay appear when the mouse is idle in a game. It works with this blueprint, but I cannot figure out a way to make it go away again when the mouse is moving?
spark steppe
just grab input in the overlay and let it destroy itself when an input event occurs?!
minor folio
How would I get the player's LOCAL velocity in Blueprints?
spark steppe
@frank lantern if its UMG look at your blueprint of it, you can create an override for On Mouse Move
in that override you could hide/destroy the widget
maiden wadi
@minor folio What do you mean by local?
minor folio
@maiden wadi Like instead of using the global x, y, and z, I want to use the local axis
For example
If I hold w (with global velocity) and turn to the right 45 degrees, then my velocity is gunna look something like 2.5, 2.5, 0
But i want where if I hold w and turn 45 deg., then it should look like 5, 0, 0
if that makes sense
Maybe there's a way to convert global velocity to local by also giving the function a rotation vector
or something idk
maiden wadi
I think I understood right, let me test something quick.
spark steppe
can't you just rotate the velocity vector by the player rotation?
minor folio
What node do you use to do that?
maiden wadi
maiden wadi
I was in the middle of trying to math that out manually. Wasn't even thinking about the rotate nodes. Too much C++ lately.
maiden wadi
I've warmed up to it. Once you start making more complex functions, C++ makes life so simple. Not to mention the speed difference is more than notable.
spark steppe
can't wait for a linux build of rider for unreal
minor folio
I don't like cpp because the compiler errors are so fucking vague yet c++ is the most complex language to ever exist
frank lantern
@spark steppe I am sorry, I am new in this software, so i dont really know what that means... It is in the character blueprint. Can I do it somehow by dragging notes from "false" ind the branches?
spark steppe
just do that override in your logo overlay widget blueprint
frank lantern
@spark steppe i dont have that option when it is an event? The BP doesnt work when I have it in the widget blueprint, only as an event in the character blueprint
@spark steppe
spark steppe
thats not the blueprint of the logo overlay
the hiding doesnt have to happen in the character blueprint
it can happen in the logo overlay, thats why you should add an on mouse move override in the logo overlay
as soon as the mouse moves, it can hide/destroy itself
also you are creating an infinite amount of logo overlays if im not wrong
you should bind it to a variable in the character and check if its populated before creating a new one
and comparing the axis value like that also won't make any sense
😄
frank lantern
Omg I didnt know that, but you are right. They are just stacking.
I still dont really understand haha
Sorry. but thanks a lot for explaining. I need to see how the nodes should look to do it.. will keep on googling 😂
spark steppe
you can actually remove that branch which checks the value of the mouse axis
just retrigger your delay when an mouse event occurs
frank lantern
Thanks!! so what about the float values?
@spark steppe This is what you meant right?
spark steppe
yes
now connect to the return value a succeed (or success, not sure how it was named) node
and before returning you can destroy/hide your widget
(the succeed node is just necessary to get rid of the warning of the output node)
frank lantern
It will not let me add the succeed as return value 😦
spark steppe
wait im starting studio, then i can make you a screenshot
frank lantern
Thank you so much <3333333
frank lantern
ok thanks! Do i still need the variable in the character BP?
spark steppe
yea
frank lantern
which kind?
spark steppe
overlay logo object or the generic widget object
frank lantern
Ok thanks and what about the float values in the mouse X and Y?
spark steppe
you don't have to check them
mouse move is mouse move, no matter what the values are
spark steppe
yea kinda like that, just that current menu is whatever you named your variable
thats what you execute when the menu should show up, so at the completed output of your retrigger node
frank lantern
This is in the widget BP? or character?
spark steppe
in the character
anyways, i have the slight feeling that you dont have any idea of what you are doing 😄
frank lantern
Hahaha you are completely right about that!! but I am really trying and thanks to you, Im slowly getting closer to what I want to do 😄
spark steppe
thats what the alternative check should look like if the first suggestion wont work
spark steppe
frank lantern
thanks again! still not showing up :((((
spark steppe
does overlay event ever fire?
either watch it with your player as debug object selected, or put a print string in between so that it shows you a message
spark steppe
wait what are those custom events?!
that looks like you replaced the mouse events by something
frank lantern
Ah yessss i see that!!! dont know how that happened
It converted the mouse events when i deleted the branches
fair magnet
@covert stirrup I were actually a bit stupid there... so... I am doing events for different skills and attacks... left click for example... and I can just set that specific skill to be any enum type I need it to be... :D
carmine prawn
Looking for some assistance it possible.
I have 2 actors. With actor one I get a location and rotation of this actor. Actor 2 has #number of sockets at it's edges, which represent where to connect with actor one. I can get the location working fine, but am having trouble working out how to get and apply the rotation so it lines up correctly. Any advice or tips would be appreciated.
carmine prawn
Should I spawn it in, apply the rotation of the target socket, then apply the location? Or is that not right?
spark steppe
@frank lantern please show a screenshot of how your character bp looks like now
frank lantern
I guess the overlay event in the branch is the problem?
gusty shuttle
Does a Call to a Bind in a master character not get called in it's child character actors?
spark steppe
the condition is probably the problem
but i dont see why
as it checks if both objects are valid, so the error shouldn't raise
@gusty shuttle are you overriding the method thats called?
frank lantern
I dont really now if the variable is created properly?
spark steppe
@frank lantern probably it is, otherwise you wouldn't be able to connect it to the other nodes like you did
gusty shuttle
@spark steppe Negative? I just want to tell enemies that the player has died, I'll get some quick screen shots
First pic is in player, after generic health loss, second pic is off BeginPlay in Master Enemy
Duhhhh, I used Unbind :PPPP
Sall good. Thanks for answering @spark steppe
spark steppe
ok 😄
@frank lantern can you just connect the first is valid check to the branch condition input and try again?
frank lantern
i tried, the error still occured
but have a feeling that the logo overlay variable i created is not really connected?
spark steppe
show the details of your variable then
frank lantern
@spark steppe do i have to somehow connect the variable to an object?
or set it as something
or thats maybe what i did in the lower part of the BP image
spark steppe
is the variable type an object reference of overlay logo?
anyways im heading to bed now, maybe someone else can help you with the mess that we created
or has an better approach
and connect the false output of the branch to the execute pin of the create widget node, before you forget about that
frank lantern
yes it is
thanks so much for your time!!!
@spark steppe well that overlay is showing up now! But only when the game starts, and then it dissappears when moving the mouse and never comes back 😂
hearty gazelle
Hey guys, I have a question.
So my character is set to this
In midair he moves, but he still does the running animation
how can i stop him from doing that
trim matrix
@hearty gazelle what do you want him todo instead?
hearty gazelle
just do idle while hes floating
unborn maple
i fix my issue didnt know i had change the collsion on the box so that why it wasnt registering the hit.
trim matrix
You are going to have to change his animation graph and anim BP
Unless you want him to forever idle, then you can simply change the skeletal mesh settings to not use an Anim BP and instead just only use the idle animation.
hearty gazelle
Well i still want him to shoot
my template is fps
but i think they are seperate right
trim matrix
Oh well i think the shooting is an animation montage, which in order for those to work right you still need a anim BP I believe. Since you’ll need to setup the Anim BP to use the correct Slot for the anim montage.
I would suggest looking up some tutorials on animation graphs and anim BPs.
hearty gazelle
Ok
trim matrix
Good luck
trim matrix
Oh?
trim matrix
Ah yea. Well that is one way to fix it. Your anim BP never thinks it’s moving now
Anyways maybe still look up some tutorials on that. It’s good to know the basics of how that all works
hearty gazelle
Yeah that is true, thanks.
thin ferry
anyone use GetViewportSize node? I am curious what kind of offset is on this... I am drawing lines to the HUD and they are off... and if I dont add a little the line never draws to the end of the screen.
odd ember
@thin ferry multiply by .5
rough wing
@thin ferry there should be an option to get viewport scaled by DPI
sonic pine
Hiho i have createtd a HUD (Skill-, Health-, Mana- and EXP Bar) for my first Character now im Created a second character. Have i duplicate the Hud or can i use the same for more than one Character?
thin ferry
oh its not dpi... cause I printed string for test and it says 1920x 1080 i think it was at the break vector 2d
sonic pine
Normaly if im starting a game i have an empty skillbar, full HP and Mana and 0 exp on each character so whats the different between ?
proud surge
Hey, I was just wondering if there was any way I could spawn an actor on top of another static mesh actor? I want to do it so that the spawned actor is on the surface of the other actor and it follows the other actor around. I tried searching this up online, but I couldn't find anything useful.
odd ember
@thin ferry did you try multiplying by .5?
vale seal
I need a tutorial on how to have it so I press a button while near a box, that box teleports above my head, then as i walk it says there, then i press the button again, it teleports back to the floor; practically picking up and putting down.
trim matrix
the highlighted custom char isnt that supose to be a round blue ball and not a blueprint icon ? or is that changed?
whas does this mean please?
thin ferry
@odd ember multiply which by five? I couldnt find scaled by dpi node...
odd ember
viewport size
thin ferry
errr 0.5 i think you said
odd ember
I mean it's going to pivot your viewport to start from the middle instead of from a corner
somber falcon
choose
odd ember
select node?
flat raft
Select String Thanks!
thin ferry
hmn interesting... thanks @odd ember I will play with that.
unreal fossil
how do you store blueprint function or procedure into a variable?
odd ember
you use cpp
unreal fossil
thanks
thin ferry
well i made a mess of that whole .5 thing lmao
odd ember
at best BP can offer ternary operators for functions
or well you can go hacky and use a string
unreal fossil
i was thinking to make a generic popup window with couple buttons. Those buttons onclick procedure can be assigned with a function.
odd ember
are you just talking about binding delegates? if so that's built in
unreal fossil
oh, it's called delegates?
odd ember
well no
they're called event dispatchers
but they are delegates in function
I have a modular UI element that I reuse all over with a binding like that
the buttons do and say different things depending on where they are located
unreal fossil
so the button sends an event, we assign a procedure to an event?
then when the even got triggered, the procedure then called
odd ember
yeah so an event and a function is intechangeable lingo in blueprints
behind the scenes it looks different
but they're functionally (hah) identical in BP
unreal fossil
ok, cool. thanks bro
odd ember
anyway event dispatchers are delegates, delegates can help you setup event subscriptions if you're aware of the observer pattern etc.
unreal fossil
yeah, I'll use my observer mindset when working with generic buttons and widget such as popups
vale seal
What am I doing wrong here? How do I make it so when I hold F down, the blueprint is teleported constantly to the player?
vale seal
how do i wire it up
odd ember
you google a tutorial
vale seal
i wish the wiki was more indepth 😭
odd ember
youtube is really going to be the best resource for learning this stuff
unreal fossil
grab timer call function block, set loop to true, and the time (in secs), and the function name
it basically works like setInterval in javascript
proud hull
@vale seal blueprints have a built-in infinite loop called EventTick. Not recommended to use it for many things, but in this case it would work for you. Something simple that is only triggered when a key is held.
odd ember
I always recommend using timers over event tick and just turn tick off but yeah event tick is an option
proud hull
Your F key would set a boolean variable to true when pressed, and set it false when released. EventTick will have a single branch node with this boolean variable plugged into it and on true it does the teleport.
vale seal
grab timer call function block, set loop to true, and the time (in secs), and the function name
@unreal fossil ?
event tic, huh
i'll have to look into it
odd ember
@vale seal look up a youtube tutorial
for real
it's going to save you so much time
and headache
proud hull
Timers have a bit more tricks to them. You basically do the same thing I mentioned except in a few different places.
Setup the timer on begin play, save the output of the timer to a variable, then instantly pause it. Then the F key will simply unpause on key pressed and pause again on key released.
odd ember
or you could just use the timer directly on the key lol
no need to pause it
cleanup on release
etc.
proud hull
Why would you constantly recreate the timer over and over?
When it has built in pausing functions.
Simply by seeing the project using F key for this task, I assume the key will be pressed often since that is a common hotkey.
vale seal
eek
teal burrow
I believe sweep is only caused by SetActorLocation with Sweep = true
shadow saddle
@teal burrow this?
teal burrow
Yeah, but generally you'd avoid that node for collision
stuck fossil
Can I pick the brain of somebody who knows a bit about the "Get (a copy)" node when using a "get all actors of class" node? I apologize in advance if my terminology is a bit off, I've been mostly learning with a "hunt and peck" method so to speak, but I'll try and explain my question as best as possible. Basically I have a spawner blueprint with multiple instances of the same blueprint in the level, and I'm casting to it from inside a game instance blueprint to call a custom event. I noticed if I change the integer on "dimension 1" I can select a single specific instance of my spawner based on the order that I placed them, but some of what I've read online suggests that just because that works in the editor doesn't mean it'll work the same way in a packaged product. So if that is the case, I was wondering if I could set up something like an editable integer on my spawner, give each instance their own unique number and line that number up with the "dimension 1" pin inside my game instance blueprint, but I have no idea how to do that cleanly or if I can even do that at all, or if it's even actually necessary if just changing the integer in Dimension 1 is enough.
Im just now realizing thats a huge wall of text and I apologize for that
odd ember
getting ref will technically get you an object pointer. getting a copy will get you the data from the actor
shadow saddle
@teal burrow so if sweep = true , i can access to whatever is inside the sweep result?
odd ember
although I'm not sure in which context BP uses copied data from actors
I reckon it is always a ref when it is actor
teal burrow
Sweeping should be only used for when you're moving an actor in an irregular way with SetActorLocation
odd ember
and the fact that get copy exists is a generic expression from the array itself
shadow saddle
teal burrow
I'd assume the thing you want to do is get a hit result from a sword
shadow saddle
yes
i use two method , hitbox collision
and trace channel
trace channel can give me impact point
hitbox collision wont
stuck fossil
So then I'm probably using the wrong Get node then?
teal burrow
I myself use a custom melee model that traces a shape
shadow saddle
i need impact point for doing the " when enemy hit my shield there is a particle effect and play on hit sound"
odd ember
So then I'm probably using the wrong Get node then?
@stuck fossil I reckon it doesn't make a difference
but you can try and see for yourself
teal burrow
Other Comp returns the thing that your colliding component has hit
odd ember
note: it doesn't make a difference when it comes to ACTORS
other things may still be fair game
teal burrow
E.g. when you swing a sword and it hits an object, Overlapped Component is the sword, Other Comp is the object
stuck fossil
Okay fair enough, I think thats enough info to point me in the right direction here. Thank you!
teal burrow
Yeah, as long as it has collision
shadow saddle
ah
let me try out
what method would u recommend for hitbox detection , use the sword own coli , make box coli for the sword, or sphere trace
proud hull
@shadow saddle depends how accurate you want the hit testing to be. If your shield is a separate actor itself and added to other actors that equip it, you can get away with using overlaps like you are doing.
teal burrow
I myself use box traces, like this https://www.youtube.com/watch?v=dGY9hcJnGr4&list=PL7J-TdxpvG5x9SrElWY54BT3ZG9p4Uiwn&index=27
vale seal
still can't find any useful vids tbh
proud hull
Personally I went for everything having a box collider and then I do a box trace that is activated/deactivated by animation notifications.
My project deals with hits on a per bone basis so I needed to use traces.
shadow saddle
alright
proud hull
@teal burrow damn, how often you do that trace, per tick? I went with 25x per second which seemed like a good balance.
shadow saddle
its very very frustrating when u trying to implement some feature
u look for 3 different tutorial
teal burrow
I do per tick since I use animation data
shadow saddle
each with their own method
then u just cant proceed sometimes cuz they are using diff method than yours
for example the 3 method i mentioned
teal burrow
Also because per tick only depends on the server tickrate, I'm doing for a MOBA
proud hull
I guess if it only runs during the attack itself it doesn't really matter, hehe
teal burrow
Yep
Tbh me lad
My project has remade some things that exist in the engine
That hitbox, projectiles, abilities I've all done from scratch
I know how to do stuff in a way that I can customize at will
shadow saddle
proud hull
Programming is great like that. A million different ways to make the same thing.
teal burrow
There was a GDC talk I watched that talked about camera shakes
Lemme see if I can find it
shadow saddle
nice
teal burrow
Basically, don't use randoms, there's a formula you can use to make it look much more natural
shadow saddle
btw it works
this other comp thing
thank you
now i can get rid of sphere trace
teal burrow
shadow saddle
ahhhhhh
vale seal
Your F key would set a boolean variable to true when pressed, and set it false when released. EventTick will have a single branch node with this boolean variable plugged into it and on true it does the teleport.
@proud hull aight what've I done wrong? i've watched about 3 vids and am still struggling !!
shadow saddle
thank you
teal burrow
If you have a second monitor and nothing to do, I recommend leaving GDC talks there
You soak up some info that may be useful
hollow cape
@vale seal just jumping in to this, but your branch has no condition, it's always true
vale seal
ah
proud hull
@vale seal right-click that red pin on your branch node, and then select "promote to variable" or "make variable" or whatever its called, haha. Then use the "set" node of that variable in your F key event.
vale seal
WHen I press F it doesn't give an output ?
to cheer me up
hollow cape
you need to create a bool variable, and set it to true/false as you press/release F
teal burrow
shadow saddle
anyway ill look into the video thanks
hollow cape
I'll defer to Slash since he's been helping you already
proud hull
@vale seal you may be better off watching some introductory tutorials. This is some very basic stuff.
vale seal
What're some good ones?
proud hull
Not sure, haha. I personally can't stand videos, no good way to search through them for specific info.
teal burrow
I'm out of ideas too, I self-learned UE4 starting since 4.0
proud hull
Understanding logic is the main key. With a good grasp of logic flow you should be able to understand how nodes work.
vale seal
Then use the "set" node of that variable in your F key event.
What'd you mean when you said this
teal burrow
I think not
But from the formulas you see there you adapt the shake to a path from an attack
proud hull
@vale seal after you create a variable, you can see it in your list of variables on the left. You can drag that variable to your graph and select "set" so you can set it true when F pressed and false when F released. "Get" and "Set" are the two inherited functions of any variable you created. Get will let you use its current value and Set will let you change it.

🤔 not working

What blueprint are you currently working in?
Do you have the default value of that boolean set to true?

proud hull
Is this the blueprint of the character you plan to use as the player character?
vale seal
where do i set that
I've put the blueprint on an object
is this testing if the object presses F or me ?
surely that's not a thing
teal burrow
That teleport doesn't really do anything
All you do is teleport it to where the character is currently standing
Which does nothing
vale seal
aaah
proud hull
To set default value of that boolean variable, select the variable and change it in its details on the right.

Or is that in your interactive cube

What node has the boolean
proud hull
"New Var 1" is your boolean variable.

I have a separate question, which is regarding the Game Mode blueprint
It looks like the Event Tick runs every tick, but an array I'm working with only updates when I put in keyboard input, not mouse input
So I can move my mouse around and there's no update
but as soon as I touch any directional key (WASD)
it updates
can I work around that?
surreal peak
That doesn't sound related to the GameMode, but rather to whatever you are doing there.
wraith wraith
yeah it's because i do that on my character blueprint not on the wb
but anyway it should work

@surreal peak Is it cool if I get a recording and post it here for reference?

You should also start printing some values. Is that Interaction Array even properly filled?
icy isle
It is filled, yeah
I'm watching it
and it has the correct values in it
I'm using a map because I need to access the specific actor at the index of the closest distance
which I'm not sure how to communicate through just an array of distances
surreal peak
- You aren't clearing that Map, so you might deal with old values.
- You are adding into the Distances array in the same order you iterate over that Interaction Array, so the Indices are equal anyway.
icy isle
I'm not sure 2. is necessarily true all the time, since some actors may remain in the array while others are moved out, and then re-added later so they can move from e.g. index 1 to index 2 in that shuffle
- is definitely right and a dumb oversight
but help me understand 2. better, since I feel like this is okay
surreal peak
So, given this happens all in one frame on the same thread, you are looping over the Array and for each element you add to an empty Float Array.
icy isle
Oh shit you're right
surreal peak
Next frame, this repeats
wraith wraith
then do that on your pc @trim matrix
surreal peak
So you have the current array anway. There is no "old actors that remain" etc.
icy isle
Yeah, if they're added/removed from/to one array
same happens in the other
gotcha
thanks
surreal peak
Yeah but next frame you have these updates and everything is reset (if you clear that float array)
icy isle
yeah let me turn it into an array and clear it after loop completion
and see what happens
odd ember
I haven't really been in the conversation but is this one of those times where there should be a PQueue available in BP? 😅
surreal peak
maybe, but you can always say "There is a better structure or type for this and it's not available in BP."
Here it's mainly programming errors
odd ember
true I guess. PQueue is just the one thing I've consistently found myself looking for

I have a mesh with a socket positioned somewhere along the edge of the mesh. I would like to use that socket as a improvised pivot point. Can anyone shed some light on the best way I could work out the transform I would need to apply to the scene root to achieve that?
rough sinew
@carmine prawn I don't there is a easy and clean way to do that unless you want permanentely change the pivot point.
It is not that you can't but some vector maths is probably needed.
carmine prawn
Yup. I know I could set up an actor BP and use scene components, however the sheer number of meshes (which will only increase over time) make that approach less than favourable. It's easy enough to work out a location transform, but getting the rotation and location is another matter hence this question 🙂
rough sinew
@carmine prawn You can set you mesh as a child of other with the proper translation (maybe it is what you said already) and rotate the parent. If it is like you said, for many actors, it will be cumbersome.
carmine prawn
Yeah, that's what I said 🙂 I'm sure there is a mathematical way of solving it, however my limited knowledge of both maths and the various nodes required makes it a more.... interesting challenge 😄
I should point out that I'm not looking for anyone to actually solve it, but hope that someone may have experience enough to point me in the right direction.

Anyone had much experience with the new "Time of Day" lighting system. I am trying to tone down the bloom of the surrounding sun but it doesn't seem to respect post-process or other traditional settings. How do I tone it down?
carmine prawn
Probably in SkyAtmosphere settings, or possibly the directional light. Maybe in the SunSky if you are using that. It's there somewhere, I just can't recall off the top of my head.
rough sinew
@carmine prawn I don't really know the answer to your original question but will probably use spherical coordinates. There is a node to convert one to other (unitcartesiantopolar)
carmine prawn
Thanks, appreciated. I'll add it to the list of things to check out 🙂
covert stirrup
@carmine prawn thanks for the reply -- I did a lot of testing and found out it was a bug. The glow was effectively stuck and adding on top of it's self or not removing, it is controlled by the bloom

Is anybody aware of the performance hit of enabling "Generate Hit Events" on a whole level (2-3 thousand elements). Only some actors will be queried per event.

how can I access this area from another blueprint? with casting or any other method?
casting works but this method makes childactors' variables private
worn nebula
Hey guys, I have a sequence set up, how can I get input to be ignore up until the last frame of the sequence?
dense mica
casting works but this method makes childactors' variables private
i've solved this problem just now.. thanks anyway
maiden wadi
@dense mica You have to cast the ChildActor variable you're dragging from to your BaseUpgradeElement thing.
dense mica
yes, i thought it will just pass the base actor's variables, but its passing the childactors' variables
maiden wadi
@worn nebula Depends on how you're playing the sequence. But in short, just disable input on the player controller and the player pawn temporarily and reenable it after the sequence is done.
worn nebula
Okay I'll give it a go
@maiden wadi I tried putting in Disable input where the red arrow is, and enable where the blue arrow is. I connected player pawn to target and player controller to controller but it didn't really seem to make a difference
maiden wadi
I don't imagine it did. You told it to disable it, started the sequence, and then reenabled it a nanosecond later.
trim matrix
What is a pure cast and how do I know when to use it?
dense mica
nothing different than other, you just need to use branch to check if cast succeed or not when using pure cast
worn nebula
Oh of course! Okay I'll put a delay in, thank you!
maiden wadi
@worn nebula Something like this would work best, but a delay will work as well.
worn nebula
I like that as well, i'll give a try. Thank you for your help
maiden wadi
@trim matrix Pure cast is a simple cast. It just casts the object. This cast doesn't check if that cast succeeded or if the value input into it was valid in the first place. Pure casting has practically no overhead. Normal, or IsValid casting will check both that the input object can be cast to that type and that the object itself was valid to begin with. Normal casting is maybe 8-15% slower than pure casting from what I've noticed, but that is doing 100,000 iterations at once. It's worth noting that the 15% sounds like a lot, but using an invalid object for calls will result in a minimum of a 1300% increase in performance loss. TLDR, normal casting is safer and well worth the 15% hit for safety.
worn nebula
sorry @maiden wadi , just wondering if there's a reason you disable input twice in a row?
maiden wadi
One is for the Controller, other is for the Controlled pawn. You can feel free to remove one if you're not using inputs in one or the other.
worn nebula
Okay thank you
maiden wadi
@trim matrix Different variable type.
worn nebula
@maiden wadi This is what I've got, went with the delay, but it still isn't working, I can press E straight away after starting the sequence. Could it be the Is Hiding variable?
trim matrix
what do you mean ?
maiden wadi
@trim matrix Material Interface != Material Instance.
trim matrix
thanks !
loooll
i see now xD
still do i need to change the mesh itself to an instance then ?
maiden wadi
I'm not sure. I'd have guessed you needed to change your struct, but I don't know what you're setting up or doing.
worn nebula
I think I found the issue
maiden wadi
@worn nebula Ah. This is my bad. I didn't realize you were in the level blueprint. I'm not sure what the Level blueprint technically is, but since it can have input I'm pretty sure it's Actor based. You might just add a third Disable/EnableInput, and plug the Controller into the PlayerController port, and leave the target to Self.
trim matrix
hioe u found mine problem xD
worn nebula
Yeah no worries, I think what I was doing wrong was trying to manually stop movement input through blueprint, when in the level sequence you can already disable movement input, much smoother, I was using the disable E input as a work around
Thanks for the help though!
trim matrix
@maiden wadi thank you alot
can you maybe explain me the difference between material interface and instance ?
grizzled garden
guys i enabled camera actor how to disable it?
maiden wadi
I don't know the exact differences personally. MaterialInstance seems to inherit from MaterialInterface though, so MaterialInstance is basically an extended version of a MaterialInterface. In this case, it's like saying Actor and Pawn. All Pawns are Actors but not all Actors are Pawns. All MaterialInstances are MaterialInterfaces, but not all MaterialInterfaces are MaterialInstances.
grizzled garden
ok

@maiden wadi thanks now i know more

anyone got any ideas on finding the point at which two splines cross?
carmine prawn
get the location at distance along spline for both splines and compare the two, when they match up you know where they cross. You'll have to decided yourself how to increment the distance, and maybe allow for some error/offset in the comparison.

frigid ether
I'm making a bullet penetration system and so far it works fine, but I need some help.
I want to give every actor a tag, which I then give parameters in the bullet blueprint to decide how fast I want the bullet to be going when exiting. Right now the 0.5 is the speed of the bullet every time it collides with something but I want more control
rough wing
@frigid ether Use physics materials and assign values to each of them
And when the bullet hits them it can get the surface's physics materials
And decide what speed to exit
frigid ether
Where do I find the surfaces physics material?
rough wing
idk
right lick on content browser
click*
Physics>>Physics material
or something like that
And then you can set the physics material by clicking on the component and scrolling down until you see physics material

How should I stop Movement Input when a certain event happen?
weary jackal
If you only want to stop movement then add a branch in the bool that checks. If you want complete input disable like movement and mouse. Then use disable input. You can enable it as well by enable input node
maiden wadi
@carmine prawn Did you ever figure out that socket transform location pivot?
@trim matrix Same way you do normally. Just use GetGameInstance and cast to your GameInstance class type. Only difference is that it'll have a world context pin, just drag off of that and type Get World. A getter called GetWorldContext should show up.
maiden wadi
@trim matrix It definitely does work, but your logic is wrong. You can't set a struct like that. Do you see the difference between the Target pin on SetPlayerStructure(ByRef) and the rest of the blue circular pins? The diamond Target one is passing by reference. But you're getting it from the GameInstance as a copy. So essentially you're altering a copy.
Actually, let me double check that really quickly. Because if that by ref accepts that from a straight getter node then what you have should be fine.

Im making a grappling game but its vr. iv made the grapple part in a first person bp using the character bp, however the vr mode uses the pawn bp which dose not have the "launch character" node. is it possible to have a working vr game using the Character bp? iv tryed to implement vr into a character bp but im not succeeding
maiden wadi
@trim matrix Okay. It works fine. I forget that works with direct getter functions sometimes. I'm unsure of what the issue is. I more or less copied what you have, just with a different struct type.

I have a system that is based on Event Tick that updates every frame, not ideal!
I am looking at making it only update when there is a change in the relevant variable (example being 1 second) How would I go about doing this, is it possible to get this information without the tick?
waxen mulch
Call an Custom event when you update the variable
covert stirrup
Yeah, I have an event dispatcher but don't exactly know how to detect when a second has increased without checking on the event tick
So that's the current setup, it's all bound I just don't know how to call it without the tick, maybe impossible?
covert stirrup
It's a clock that takes engine time and sets the hands to their relevant locations
Would I use the Delta second in the timer to make sure it's always correct?
or does it take framerate into account already
unkempt musk
You can also lower the event tick rate to 1 second. Have it sync on begin play, then use a 1 sec event tick.

@maiden wadi Hey Hey, Was it you that said you like using MAPS (var type) ?

Click "Class defaults", under details, change the tick interval to 1 second. "0.0" updates every frame.

Is that a binding function? O.o

Hi! (Newbie here)
I'm trying to destroy an actor with a Box trigger. I does delete from the world outliner but it stays in the world. I also sometimes get ''Kill Pending''
trim matrix
It is a binding function yes authaer
@maiden wadi
i wasnt sure if i needed to put the save game code in that aswell so i just put it in there to make sure. but i also tried it without the savegame code and its the same result
maiden wadi
I just wondered, because savegame is writing to disk. So you're rewriting that file on disk many many many times a second.
trim matrix
oof, yeah ill take care of that
You have an idea what it could be ? Because when i pick up the item the string prints 1
but on the binding it doesnt get a value of the same variable

For the GameplayDebugger if I dont have an AI targeted it should pickup my character yeah?
or am I just dreaming it works that way

Your latest screenshot is overwriting it, the one you posted earlier looked perfectly fine. How are you setting that variable in the savegame to begin with?
sudden anvil
Hey everyone
I'm quite new to unreal and got stuck at this problem
I have a key blueprint and a door blueprint (both are Actors). First one has a private variable "keyType" and secod "doorType". (there are 3 correspodning types)
I want to make each key open the correspodning door. How can I access the variable "keyType" of an instance of blueprint "Key" from the blueprint "Door" in order to compare the two?
In other words:
How can two blueprints communicate with each others' private variables?
Can that be achieved through referencing the class?
trim matrix
@maiden wadi
wait is it because i destroy the actor i destroy the value aswel ??
maiden wadi
@trim matrix Nah, you're not actually saving it to game, you're overwriting it there too.
trim matrix
iam new to saving, so followed a tutorial and thats where it got me 😛
maiden wadi
What you're doing is fine, up until the SaveGameToSlot after the string. Basically what is happening is that the LoadGameFromSlot is creating an object with variables in it and populating them from the disk into memory. Then returning the blue memory pointer for you to use to alter those variables in memory. But then you're not using that same pointer to save it to slot, you're just saving an empty pointer to slot.
TLDR connect the SaveGameRippyInstance variable to the SaveGameToSlot's SaveGameObject.
