So do the same thing in your listview widget.

[faint pasture]

in all 3 cases, ItemData should be the EXACT SAME STRUCT

[agile ermine]

exactly

Data Table shares SAME INFO for every object inside

[faint pasture]

Struct ItemData can hold the class for the world actor

so given a struct, you can spawn the actor (dropping and item)

and given the actor, you can get the struct (it's just a field on the actor, that's for storing an item)

You can use data tables as the master list but it's all the same.

So then for the world list view, when you overlap a world actor

Overlap -> Get ItemData -> Add ItemData to NearbyItemDataList -> Update UMG
End Overlap -> Get ItemData -> Remove ItemData from NearbyItemDataList -> Update UMG

[agile ermine]

pretty simplified but correct 😄

[rigid fractal]

actually, there are two collision box, one on the object and another on the character, the collision box that is on the player is the one i use to detect when an item is nearby, so i get the name of this object (item) that was collide and i execute this function, where "item" is the name of that item

[drowsy ridge]

Tried the bool method, didn't work too

[faint pasture]

And for when you overlap an InventoryActor

Overlap -> Get InventoryActor -> ForEach ItemData in ItemDataArray -> Add ItemData to NearbyItemDataList -> Update UMG
End Overlap -> Get InventoryActor -> ForEach ItemData in ItemDataArray -> Remove ItemData from NearbyItemDataList -> Update UMG

[agile ermine]

you don't need any extra parts in your Player

you can check for collisions agains a specific part of it (f.ex. Capsule Component)

[rigid fractal]

i know, is that i preferred to create another box where i can have greater control of the area where the items will appear

[agile ermine]

this is how you can make sure only specified Component is able to trigger an event

[agile ermine]

not true 😛 but if you're unexperienced then you can handle it that way

but math is your friend in UE4 / programming overall

more components = more things to update all the time, check their overlap etc.

so you just use more of your RAM

sometimes you also don't necessarily need a component persisting all the time - you can Add Components on runtime

and then destroy them once they done their job

as an example:

You have a rocket that should deal Area Damage:
It hits ground, spawns Collision Sphere (with size o f.ex. 1), then resize it to your desired size (you have to do it that way, it will not detect Actors inside of it if you spawn it with already desired size) and then perform code of applying damage

Afterwards everything gets destroyed

[drowsy ridge]

Figured it out mate! I'm a knobhead for using do once in the receivenotifytick @agile ermine

Worst programming habit

[agile ermine]

haha, didn't realize that as well

it's almost like placing delays in the Loop iterations XD

they won't work as we may think 😛

[rigid fractal]

a lot of things to change, hard 😔

[agile ermine]

yup, hate that as well

changing and re-adapting the code again so it works with the project together

[rigid fractal]

worse than i spent all night last night doing this and thinking of a way to solve the problems, thinking it was good 😅

[maiden wadi]

Technically didn't need to change much. For the containers you could have used a different list view.

[rigid fractal]

i cant think straight, i couldnt understand much, but i will think of a solution

[maiden wadi]

But I feel you. Currently in the middle of ditching Prefabricator. Not nearly as nice as I was hoping. I can't even change an instance's collision without affecting every other prefab spawned after it. 😦

[gentle urchin]

Rip !

[viscid barn]

Alternatively, you could create a new type of collision channel and make it so your component can only interact with components of that channel, negating the need for that check

[odd ember]

have you considered making your own tool?

[fast escarp]

@dusk ember ALSV4 comes close, but the blueprint version doesn't have replication.
https://www.unrealengine.com/marketplace/en-US/product/advanced-locomotion-system-v1
I don't do networking outside C++ so I'm not sure how you'd rep it in blueprint, but somebody already made a C++ port of this which is replicated and you can expose to BP if they haven't already.
https://github.com/dyanikoglu/ALS-Community

they have some posts on their discord for setting it up to use BP as well you can take a look at

[dusk ember]

so how am i supposed to use this with the wallrunning? sorry if i'm sounding like a noob i'm not familiar with replication

[odd ember]

you can always ask in #multiplayer

[fast escarp]

Yeah if you need specifically wallrunning you'd need to either fiddle with the C++ or restructure it some so you could expose some parameters to BP. Personally I'd avoid networking if I couldn't write C++ but maybe thats a hot take.

[odd ember]

nah generally multiplayer is better made with cpp. I wouldn't consider multiplayer for early projects either as you're squaring the complexity of your project

[dusk ember]

hmm, ok

i'm trying to make a multiplayer fps game that uses parkour, but for now i can just do singleplayer

[dusk ember]

this is the error that is spamming and this is where its happening

[maiden wadi]

<@&213101288538374145>

[torn kettle]

:no_entry_sign: samosa#3563 was banned.

[hexed glade]

Hoping to get some insight here. I'm building a topdown rpg with a single shared inventory. Considering the main character is always static, would it be better to attach the inventory component to the main character or the player controller?

[maiden wadi]

Considered it. But honestly I'm probably just going to rely on soft class actors as prefabs for what I need.

[maiden wadi]

Sounds like something you'd put on the GameState, or a GameState ActorComponent.

Realistically, some of the best inventories are just ActorComponents, so it won't matter where you choose to put it in the end. But if it is meant as a party wide inventory, or a multiplayer game where everyone can access it, it should probably live on the GameState.

[hexed glade]

Can you directly influence the character from the game state, such as equipping and using items on them?

[viscid barn]

Most of the times I got that error it was because interacting events were being called at the same time, causing interferences

[viscid barn]

You can have the character call the gamestate to retrieve the desired variable

that said I would put the equipment references on the character directly, to reduce the amount of times you need to interact with the gamestate

[tacit parrot]

How can i get the Index from the Actor that i hit here? Is this even possible? Sorry when this is a dumb question.

[dusk ember]

how can i fix this?

also, i added projectile trails but they only appear in the client net mode not standalone. anyone know a fix?

[viscid barn]

check if you don't have another event managing your control rotation, if there is, add a rule to negate it while your wallrun check is valid

[dusk ember]

mk

[viscid barn]

I'm afraid I've yet to touch networking on UE so for that I can't help

alternatively, it could be that the way you set up your wallrun makes it so every actor of the same class try to perform the designated task while it's not valid for them, thus giving you errors

[dusk ember]

so should it be set so that it only runs on the client?

[viscid barn]

what, no

[odd ember]

that's fair. I'm considering making some small tools to help with instancing. not at the level of something like prefabricator, but similar

[viscid barn]

Just look for something that could cause interferences

[maiden wadi]

Sounds like you've done an authority switch somewhere and mistakenly only spawned that affect on remote.

[viscid barn]

to give you a more concrete example;

the latest case of that I encountered was because I had set an stat update event to trigger three events in succession: first to update the base attributes of a character, the second to update the attributes of its equipment and finally one to take the result of the previous two and combine it to get the final attribute.

The problem was that the equipment was on a separate bp component which caused an issue as the first needed more time to perform all of its math, leading to an error when attempting to trigger the second.
adding a simple delay between the two events gave it enough time to calculate everything before finally attempting to update the equipment

tl;dr: it was attempting to run both events at the same time despite the first not being done yet, making it impossible for the second to run

[jolly island]

Hello, I implemented an interface in my widget but now the widget won't compile and I get error messages saying "overriden function is not compatible with the parent function check flags exec, final, static" and "cannot order parameters in function" Does anyone know what's wrong?

[dusk ember]

well i thought what you were trying to say was that it was running across the entire server so that when one player tries to wallrun it also checks for all other players. so, i thought that you only want it to check the one client.

[maiden wadi]

Any reason your widget needs the interface?

[viscid barn]

I mean, you can run your function client side only but then you might end up with a discrepancy between what players see

(like how in early MH games, monster location was done client side which resulted in players seeing monsters in different place and thus it'd look like your friends were fighting the ambient oxygen 😂)

[gentle urchin]

Lool ! Howd that pass any qa

[maiden wadi]

You'd be surprised how bad QA can be.

[gentle urchin]

And the follow up

😅

[dusk ember]

i understand that but i just want the wallrun check to occur on the client thats attempting to wallrun, then i want it to show that player wallrunning for all others

[maiden wadi]

I mean. Cyberpunk 2077 exists. That passed QA somehow despite all of it's hype.

[viscid barn]

tbf, if something doesn't really affect gameplay quality, it's not rare for the devs to let things pass so they can focus on more important stuff

[jolly island]

It's a cursor widget and through the interface I get access to the enum that has different cursor uses like talk etc

[viscid barn]

I guess you could have the wall run check be done client side but keep the movement and animations still updating server side

[dusk ember]

whats the other way?

[viscid barn]

adding something to your function that makes it so only the character you're currently controlling is affected

but before you do that, I'd use a debug print to make sure that it is indeed an issue of several characters attempting to wallrun even if there's no wall to run

[gentle urchin]

Doesnt client-side location mismatch affect gameplay quality? :p

I suppose one can alwats find things that are worse

And i get that theres a budget and time constraint

So more important issues comes first

[viscid barn]

Depends on the end effect, in this case, seeing your friends hitting nothing while their damage is still being dealt successfully is acceptable enough to give it a pass

[gentle urchin]

Yeah i wouldnt push the deadline for it

I would patch it tho

[viscid barn]

remember that we're talking ps2/WiiU/3DS era netcode, overall stability is more important than immersion

god I'm so tired I keep making weird english mistakes lmao

[dusk ember]

so it seems that the Camera Tick function which is what causes the Camera Tilt happens on Event Tick. could this be the issue or is that how it should be?

[viscid barn]

what do you use for your camera tick?

[gentle urchin]

Yeah its easy to forget how things have changed. Qa was way better in the ps1 era

Like.. no option to patch it, so the release had to be like 99.91%

[viscid barn]

Errrr, I mean... depends on the sector

😂

[dusk ember]

these are all the functions in order

[viscid barn]

there's a reason why exploits are so prevalent in speedruns. You can't have a bugfree game, it's just a matter of priorities and bug severity

[maiden wadi]

To be fair. It had to be better. Updates were kinda hard. There were no day two patches, or first month DLC release with major game fixes.

[viscid barn]

I'd advise against event tick

it's called so frequently that it can cause a lot of problems

[gentle urchin]

^ True. Nowadays you can get away with super buggy game as long as you do a day2 patch

[dusk ember]

is there another method?

[viscid barn]

while that's true, the day1/2 patch culture also led to a lot of bad practices

[gentle urchin]

Unless you are SimCity and dont expect fanbase to flood the servers for 2 weeks

Yeah, personally i hate it.

If its not ready to be shipped, dont ship it..

[viscid barn]

An easy one to use is SetTimerByEvent

[gentle urchin]

I dislike early access aswell

[viscid barn]

then you can decide how frequently you want that timer to loop

[gentle urchin]

Not because of it being early access, but because of the abuse of it

And the amount of cashgrabs that just doesnt commit to it.

[frail pilot]

what's the name of the node that has the tooltip above?

[maiden wadi]

Part of that is publishers though too. You'd be surprised how little control you really have over your own game when you sell your soul to a publisher.

[gentle urchin]

And just ditch it once they make some promises

[viscid barn]

personally my camera is set on a 0.1s tick, it's fast enough to feel smooth without taxing the system too much

[viscid barn]

addtimeline

[dusk ember]

what event connects to the SetTimerByEvent?

[viscid barn]

timelines are also a nice way to set ticks but they're not available on all types of graphs

[viscid barn]

here's an example of how I set up an timer by event

the settimerbyevent is activated by beginplay

if it's not clear enough tell me and I'll try to summarize what's going on

[dusk ember]

so in yours you have a custom event connected to the SetTimerByEvent, but there isnt a custom event in mine. its calling a function i believe.

actually

wait

let me see something

[viscid barn]

You need to create an event first

have that event trigger the function

the connect that event to the timer so that the timer runs that event every x seconds

for example in mine:
-my attack input event checks if the attack button's buffer is active, if it is, it tells the character to attack
-my attack input event is linked to the timer, set to be ran every frame (on a 60fps basis)
-Said timer is enabled by the event begin play

(btw you don't have to type that big ass number for 60fps, just type "1/60" then enter and it'll do the math on its own, this is valid on all nodes afaik)

[dusk ember]

so it works but i have to set the time to 0.01 or else the camera tilt gets really weird

[viscid barn]

can you record a quick video of that tilt?

[gentle urchin]

I wonfer why its ran on tick?

Wonder*

Wouldnt it just be event driven?

Some catch when wallrun starts and ends?

[viscid barn]

changing the type of tick shouldn't cause ticks normally

[gentle urchin]

True, its just wasted i suppose

Event sets the offset

Tick checks if current rot != offset

And RInterp or whatever if they differ

[viscid barn]

that's cause your tilt adjustment is too slow

can you show my your tilt bp? it's probably a lack of RInterp as Squize said, or it's update value being too low

[dusk ember]

i think its the interp speed

lemme check

[gentle urchin]

Rinterp eases aswell.

While rinterpconst dont

[dusk ember]

it was the interp speed

[viscid barn]

😄

[dusk ember]

lemme find a good value for it

[viscid barn]

0.01 is even lower than delta tick if I remember correctly so yeah, best not use that

[gentle urchin]

Yepp

Better to just use tick then

[viscid barn]

calling on a 100fps for something as constant as a camera is a good way to mess things up if you add too many 😂

[gentle urchin]

As its ment to be used

[viscid barn]

UE4's event tick is actually rarely used, it's usually kept for very specific things as it's quite ressource heavy

[dusk ember]

its a bit stuttery when i jump on/off and i think thats because its at 0.1

[gentle urchin]

Well youd use c++ tick if you can/know how to

[viscid barn]

unfortunately a lot of youtube tutorials don't really take that into account and it works fine for them because each is set in their own project

[gentle urchin]

I use tick for lots of things

Only when necessary tho

[viscid barn]

ah yeah but that's two different kinda ticks hahaha

[gentle urchin]

For dure

[dusk ember]

the most i know in C++ is a print statement lmao

[gentle urchin]

Magnitudes of difference

You know more than me

[viscid barn]

not to mention c++ is a lot less consuming than bp so even if it was as frequent as event tick, it'd even out

[gentle urchin]

But got a few hundred lines in there by now

[viscid barn]

what kinda camera do you use? boom attached to character or separate individual?

[dusk ember]

well in the viewport theres a follow camera and a camera boom attached to the mesh

[viscid barn]

hmmmm

if its attached the the character it shouldn't normally stutter when it moves

[gentle urchin]

Unless code is trying to override its location

😄

[dusk ember]

i'll record it

[viscid barn]

Oh indeed

[gentle urchin]

But stuttering probably is more noticable at higher speeds aswell

[gentle urchin]

Increasing the interp speed

Looks like to high speed imo

Whats it at?

If you go 0 to 100 in one frame, the i terp is wasted 😅

[viscid barn]

Yeah I think your camera is updating too fast lol

[dusk ember]

its at 85

[viscid barn]

try halving it

[dusk ember]

its still stuttery it just takes longer

this is the camera tick event btw

[gentle urchin]

.1?

Rip

[dusk ember]

what should it be?

[viscid barn]

I meant the camera's bp

[dawn gazelle]

If you're adjusting something that moves, you should probably just use tick instead of a timer.

[gentle urchin]

Interps are made to be driven on tick

[viscid barn]

OH wait

you're using ALS's?

[dusk ember]

?

no?

[viscid barn]

Oh

hmm, weird

[dusk ember]

heres the camera tilt

then this is the camera tick

[viscid barn]

weird thing is, I'm using a similar setup and yet I don't have no stutter like this

[gentle urchin]

I'd still consider using pure tick instead but oh well

Camera handling, movement, interps

All belong to tick

Easily gated

[viscid barn]

Well, so long as you don't overuse tick it's fine to have the camera on it

[gentle urchin]

Exactly

[viscid barn]

though I must admit I'm not sure why yours is behaving like this

[gentle urchin]

To keep things clean you can do it in the cameramanager

[dusk ember]

the whole problem i had was that i was getting an error spewing out repeatedly when i went into multiplayer

[viscid barn]

do you still get the error after swapping to event based?

[gentle urchin]

Multiplayer..

Always

Makes me cringe

[dusk ember]

here was that error

[dusk ember]

yeah

[viscid barn]

Also, took a while to register in my brain but yeah, it's your interp speed, because you're no longer on a 0.13s update base

ofc an interp speed of 80 will result in instant

[gentle urchin]

Update brain freq pls

Jk 😅

[dawn gazelle]

Where are your running this code? In the character or the controller?

[viscid barn]

try an interp speed of 5

[dusk ember]

a component

[dawn gazelle]

That is on the character?

[viscid barn]

your camera updates a hundred time slower so ofc you need the interp speed to scale

[dusk ember]

yeah

[viscid barn]

(assuming the event based tick fixed your error)

[dawn gazelle]

Ok, then the error is most likely being caused because this is also running on other clients. The other clients are setting the character reference, but other clients do not get other client's player controllers.

[viscid barn]

otherwise you can go back to the regular tick

[dawn gazelle]

The player controller only exists on the local client and on the server.

[viscid barn]

yeah that's what I figured as well

[dusk ember]

how can i fix this?

and no matter what the interp speed is it still stutters

[trim matrix]

Is there any way to sort an array in BPs easily from integers?

[dawn gazelle]

Probably put an isvalid check on the GetController output, only proceeding when it's valid. Ideally the camera code would only ever run on the owning player's character.

[dusk ember]

Ideally the camera code would only ever run on the owning player's character.
thats what i was trying to figure out but i didnt know how

[viscid barn]

its because your camera is tied directly on your character

so naturally if you don't specify which player's camera you want to update, it'll try to update them all

[gentle urchin]

Not sure if multiplayer is the best project at this point if im being honest

[dusk ember]

i probably wont be doing much more for multiplayer but this is all i'm trying to do for now so i at least can test it out without getting the same error repeated thousands of times

i'll wait until i understand it better

[dawn gazelle]

And special moves like a wall run is a bit more complicated in multiplayer too. You'll never get it working 100% through blueprints - it may seem like it'll work, but introduce any latency and it'll end up failing.

[viscid barn]

in all fairness, if you don't have the infrastructure to host the online side of your game, it's not going to serve much purpose beside getting some practice for the future

[gentle urchin]

Its just a commonly underestimated complex thing to setup and run properly

[dusk ember]

yeah i just wanted to be able to test this

[trim matrix]

Would anyone know like a simple way to do so?

[viscid barn]

It'll add some realism to the wallrun, land a few step then fall on the ground 😂

[gentle urchin]

It's not rocket science really, but there's a ton of things to consider

[dusk ember]

where do i put this? i tried searching for it but it doesnt pop up

[dusk ember]

😭

[gentle urchin]

Manually loop it and sort it

[dawn gazelle]

If you're searching in your component, you may need to turn off the context sensitivity.

[trim matrix]

But the sort part is the issue 💀

[viscid barn]

grab the component's owner first, then pull it from there

[trim matrix]

Lmao if I knew how to do that, I wouldn't be asking 😂

[dusk ember]

i'll probably put it on the backburner but this needs to be multiplayer. whether i learn it in a month or a couple years, i want to be able to understand it and use it within C++ so that i can fine tune it.

[viscid barn]

any interaction with controllers from a component require you to call back to the component's owner first

if you're going to use component, I highly suggest promoting the owner to a variable so that you can use related functions more easily

[gentle urchin]

https://answers.unrealengine.com/questions/803198/how-to-sort-an-integer-array-in-blueprint.html

Replace the float with the int version

[dusk ember]

how do i turn it off?

[dusk ember]

thanks

ngl im not too sure where to put it

[viscid barn]

ForLoopception 😂

[gentle urchin]

😅 had it laying around from earlier

[viscid barn]

hahaha

I mean, I use a similar ForLoop setup for enemy detection

and soft targeting

[dusk ember]

where do i use the IsLocallyControlled?

[mossy mist]

Greetings I have a sphere component that generates overlap events and overlaps all dynamic. This is used to register melee hits from the character. The problem is that enemies who use overlapping detection to register hits can hit this sphere component to register damage onto the player. This is not good as I only want them to hit the player, not its melee range. How can I fix this?

[gentle urchin]

If you dont wanna adjust the collision response

You can always add a tag to it

[viscid barn]

I'd use custom collision channels but yeah, a tag would also work

then in the overlap tell it to ignore components containing said tag

[mossy mist]

If those are the only two options then ill use a custom collision channel because tags means I have to add a tag check to every single enemy

ty

[viscid barn]

cheerio

Must say though, that is one big ass hitbox 😂

[dusk ember]

how does this work?

[dawn gazelle]

Put it into a branch and put it anywhere before you execute anything that would reference the controller of a character.

[dusk ember]

would i use it here?

[dawn gazelle]

Probably before executing that function entirely.

[viscid barn]

yeah

[dusk ember]

ah ok

[viscid barn]

the earlier the better

[tulip mason]

I use a trace notify on attack animations that looks for hits that are proper.

That way does look lik a huge headache to get working.

[mossy mist]

wait thats actually a good diea

*idea

ill try that ty

[viscid barn]

if it's in a component rather than an actor bp

woops ignore that lol

[dusk ember]

it worked! tysm!!

[dusk ember]

the locally controlled fixed it

[viscid barn]

I copied the nodes instead of taking a screenshot lmao, didn't mean to do that

[dusk ember]

i'll figure out the stuttering thing later, but the error constantly outputting is gone and thats enough for me today 😂

[viscid barn]

I mean, as I said before, if it's only your camera you use the tick on, that's fine. You can go back to it.
it's just keep in mind that in general practice, bp event tick will quickly hit your game's perf if you rely too much on it

[gentle urchin]

Even c++ tick does!

[viscid barn]

yeah

[gentle urchin]

Im using like 8ms on 4k agents

Sad

[viscid barn]

but bp tick has the added deficit of bp being a major ms killer by default 🤣

[gentle urchin]

True !

I gained 8x performance going from bp to c++

Litteraly the same code

[viscid barn]

😂

it's insane how bp can make your ms go from 40 to 600 😂

[gentle urchin]

Yes !

😂 i was amazed

[faint pasture]

Have it ignore WorldDynamic

[mild ibex]

Is there a way to make the door open smoothly in Editor instead of snapping into place?
Im using a custom event to open and close the door but it snaps into place rather than just opening like it otherwise would on runtime

[gentle urchin]

Dont think you can do timelines on editor events

This sort of prooves it

[mild ibex]

i figured, is there a better solution? Or any solution to this LOL

[gentle urchin]

May i ask why you need it

[mild ibex]

simple curiosity

[gentle urchin]

Then no , there is none

[mild ibex]

fair enough

[supple bane]

is there a way to spawn a plane by getting the locations for each corner?

[devout latch]

Show your curve

in the timeline

(I'm assuming you have a curve because that's the way you would do it)

[mild ibex]

rn this is it

it was at 0 to -90

im testing some math stuff to constanlty add rotation until a value, so that it opens

[supple bane]

basically need a way to find 2 points, and create a plane using them

[devout latch]

Where is the 0 to -90

It looks like it is going to 1 which will look like 0

[mild ibex]

this is the graph from this stuff

[dawn gazelle]

Instead of using Play From Start and Reverse from End, try using Play and Reverse - this way if it's triggered again, it'll just resume from where it was.
You can either have your timeline output from 0-90 or 0-1, but 0-1 would require an interp node of some kind.

[faint pasture]

a mathematical plane or a plane mesh?

[mild ibex]

i tried Play and Reverse but neither one does anything

[supple bane]

mesh preferably

[dawn gazelle]

Is your door mesh a child of pivot?

[mild ibex]

yes

[faint pasture]

Just spawn a plane static mesh (I think the default one is 1m x 1m).
Its scale X will be Height
Its scale Y will be (B-A).Length
Its rotation will be (B-A).RotationFromYVector

[mild ibex]

might be hard to see in the video, but in the outliner, its pivot then SM_Door

[supple bane]

thanks

[dawn gazelle]

OH you're doing it as an editor utility widget...

I don't think timelines work in editor.

[mild ibex]

ye, it works on play, i just want to see if i can get it working in editor

[tranquil abyss]

Ok so

the top picture is in my player character

but the problem is on M1 press

The ai that have the same animation Blueprint

also attack when I hit M1

I not sure how to design around this

[faint pasture]

Show the anim bp

[glass stump]

I have a BluePrint for a patrolling enemy, he goes to 'location 1' then to 'location 2'.
I'd like to have multiple of these enemies in my game though. Do I just duplicate the BP and change the locations or is there a better way of doing it?

[tranquil abyss]

@faint pasture Is above

[dawn gazelle]

Duplication is not the answer. You'd be better off making a "PatrolPath" actor that's specifically for setting up patrol paths that contains a vector array that is exposed on spawn and instance editable, and set"3D Widget" to true. This will allow you to place a patrol path actor, and add vectors to it and place them around the level where you want the thing to patrol.

Then on your AI, you can have them set up with an exposed variable of the "PatrolPath" type. When you place your enemies in your level, you can then select which patrol path they should follow - your AI should instead read from the patrol path they were assigned (if it's valid of course).

If you have an actor for spawning AIs, you can have them set up with a patrol path variable as well which you can have them feed into the spawn node.

You can make the patrol path actor a bit more advanced by having options for looping or going back and forth and wait times for each point.

Kismet libraries have functions to draw shapes.

In 3D I mean.

DrawDebugBox, DrawDebugText, DrawDebug etc

Ah, yeah. In that case, simple shapes and materials or Niagara emitters work well.

[dawn gazelle]

If the AI have the same animation blueprint, then you don't want them casting to your get your player character to get the values - change the input to the cast to "Try Get Pawn Owner" - this returns the character that the animBP is tied to.

[keen wedge]

Hi all, does anyone have any "good" tutorials on rendering a 3D object in the game world (outside of the main playspace) into UMG? At game over, I want to display three skeletal meshes, they'll be animating. I do actually have it working, following this tutorial:
https://www.youtube.com/watch?v=BnLHBJMX0cE

...but there's a minor problem in that the colours after a bit washed out - and I cannot for the life of me work out why, nor do I really know enough about materials in UE4 to fully understand everything thats going on in the tutorial.

[glass stump]

Ah, thank you! :) I'll try this out.

[keen wedge]

I hate discord so much...

First image is what comes out... second image is what the border should look like..

[maiden wadi]

I don't see why not. For basic shapes they're pretty easy to manipulate. Sphere, Box, Pyramid, etc are already in engine if you use content examples. And Sphere and box are easy to scale since they're at 100uu size.

Isn't much different if you make your own. Just have them at a default size that you can scale. Alternatively there is a plugin that allows you to create meshes procedurally. Little bit overkill in this sense though I think.

[mossy mist]

Hi I have a server rpc that calls a multicast to run a attack animation montage

that montage then has a trigger which calls a server rpc

that server rpc then applies damage to things

when the server uses it the damage is correct

but when the client uses it the damage is doubled

the animation runs smoothly on everyone

but the damage is doubled when used by clients

how can I fix this?

[rough warren]

Hi, I've got a bit of a question. I would like to see if one of the objects my object is colliding with is my spawn_zone which is a blueprint that is spawned. I'm trying to figure what actually goes in my array

[keen wedge]

Try using the class of the object instead... Loop through your array of overlapping actors, then for each item in the array, compare the class to the class you are looking for. Might work.

[maiden wadi]

You're also looking for the Contains node.

[dawn gazelle]

#multiplayer and you may want to show some code surrounding your montage, like how the damage is dealt.

[slow matrix]

does anybody know how to detect if the players health (a float variable) is below 20 health? im trying to make it so a blood vignette appears when they're below 20 health

[mossy mist]

was able to fix it anyway the solution was to not run an rpc to do damage

[dawn gazelle]

When applying damage, check if the player health < 20. If so, display your vignette. If not, clear the vignette if it is valid.

[slow matrix]

thanks

[faint pasture]

@tranquil abyssFound your problem. Instead of using Get Player Character, use Get Owner or whatever

You want the anim bp to get the actor it's on, not the Player's character

[rough warren]

like this?

[keen wedge]

Yeah... although you might want to use a For Each Loop with Break - that way, if you find it, you can jump out of the loop, rather than cycling all the way through - assumes you're only interested in "one" etc...

Also, try what Authaer suggested also, regarding the "Contains" node, you might be able to just pass in a reference to your Spawn object instead...

Depending what you're trying to do, it might be easier to tackle the issue from the other side... e.g. have the spawn_zone detect the collision and then respond accordingly...

[rough warren]

yeah that's probably a better idea

[keen wedge]

Really depends on the context, but you'll know which is more straight forward/appropriate etc - anything that saves you looping through things lots of times is a win 🙂

[tranquil abyss]

Does anyone have general tip for hit detection- when I swing my weapon I can hit the same enemy 2 or 3 times

I have tried Do Once and resetting

but that never seems to work

this is my damage logic

in my ai that is

[keen wedge]

Might not the best way, but you could try creating a boolean variable (not a local one), perhaps called "IsProcessingHit"... within the logic for dealing with the hit, place a branch to check that boolean first. Only proceed if its not already processing... then, at the end of your processing logic, reset the boolean so that it could be hit/processed again..

[tranquil abyss]

oh lol

thats an easy solution

idk I didnt think of that

[keen wedge]

As I say, may not be the best... but might move you forward...

You might want to also consider resetting it in the OnComponentEndOverlap event too... maybe...

[empty needle]

Anybody have any suggestions n why this is happening?

https://cdn.discordapp.com/attachments/221799467689574410/936988676368510996/AnimationBug.mp4

I’ve stripped the project back to nothing, and have this standalone. It’s when both UMG are hidden, and then when I bring them back they bug one of them?

#umg message

[keen wedge]

It looks like its a "focus" issue... e.g. after you'd hidden both panels, you clicked on the top button but it didn't do anything, as if it was focusing the main ui widget, first... then the second click hit the button

[empty needle]

Here is the entire project

I'm not using any form of focus, it's running an animation.

[keen wedge]

Cant open that with my current version of UE4... the map file doesn't appear, all I get are a couple of enums...

Sorry..

[empty needle]

Which version of UE do you have?

[keen wedge]

4.26.2

[empty needle]

Ah, it’s in 4.27

[keen wedge]

Sorry. It looks like a focus issue though... I'd check the UI widget you have for buttons and check that you are setting it to be focused etc...

Easy way to test the theory... run that exact test you did in the video, but before you click on the top button to bring one of them back (after both being hidden) - click anywhere on the screen (not on a button) - then click the top button...

[empty needle]

trying now

i'll make a 4.26 version

Hi @keen wedge , tried that. Still having the same issue. I click someone on the screen prior to clicking any of the buttons for it to return.

[keen wedge]

So you click anywhere, then you click on a button and it appears, yes?

[empty needle]

Nope

[keen wedge]

What, the button still needs two clicks?

[empty needle]

il'l record what's happening

[fickle nebula]

I'm spliting screen with the Create Player node on Begin Play of the** level BP** and saving that reference in game instance when I open a new level and check the game instance the variable returns None in Begin play on level BP ... Any ideia?

[empty needle]

It's actually causing the issue to happen immediately.

[umbral galleon]

I'm spawning an AI actor during runtime, but when they spawn they are not assigned an AI controller. How does one assign an AI controller to an actor?

[keen wedge]

If you can create a 4.26 build I dont mind having a quick look..

[empty needle]

Weird Widget Behaviour

[frozen spear]

@fickle nebula are you using absolute travel? That will dump the current instance and start fresh

[umbral galleon]

what method are you using to open/close

[fickle nebula]

how I know?

[empty needle]

This is how I'm telling it to identify the type of animation to play.

And this is the blueprint that plays the actual animation for the UMG side.

[odd ember]

absolute has to do with the path, not functionality

[umbral galleon]

If you follow the same sequence, but close them both with more time between them does the issue still occur?

[odd ember]

levels are always flushed

which is probably why your reference is null

because it doesn't exist

[fickle nebula]

should I save in a file?

[empty needle]

If I close them, and make sure that one always stays open. It seems fine, but the moment that both of them get closed and come back something happens.

[odd ember]

in the game mode you might have an option for a "seamless travel" actor list

these are the actors that are carried over between levels

I can't remember if it's exposed

[fickle nebula]

oh ok

[odd ember]

by default player character, controller and game mode should be in that list

[fickle nebula]

I checked that

[odd ember]

but if you have multiple players then that may be different

[odd ember]

yes but you have to use the list as well

[fickle nebula]

I'm mirroring tha character

[odd ember]

I don't know what you mean by that

[odd ember]

right but it's still a separate character that you need to add to the list

with, probably, its own controller

[umbral galleon]

What is happening in "Check is Already Open"

[fickle nebula]

In the level blueprint

[fickle nebula]

If I create player again on the next level is going to be 3 screens, so I thought I could just posses again that one I first created

[odd ember]

yeah but since levels are flushed when changed, you don't have a reference to that character

[empty needle]

I've uploaded a copy of the project in 4.27

[fickle nebula]

the next level

[odd ember]

like I said

[odd ember]

your reference doesn't exist

[umbral galleon]

Your issue is occurring in the Widget Animator Play obviously since it's detecting it's "Open" when you click, but not playing the animation.

[odd ember]

because the level is flushed

[fickle nebula]

the reference of the character?

[odd ember]

yes

[fickle nebula]

event if I just placed it there?

[odd ember]

then it will be another character

not one from a previous level

[umbral galleon]

is the bool in Check Already Open unique?

[odd ember]

if you want the same character to persist through levels, you need to use the seamless actor list

[empty needle]

The odd part is, it works really really well when you continuously click it. But when two are on the screen at the same time they seem to be impacting each other. Which doesn't make much sense, as they are 2 different widgets.

[fickle nebula]

yeah it ok, I just want the camera to posses the new one

[odd ember]

that is the only way

[umbral galleon]

right, something has to be overlooked somewhere - from what you've shown the Check Already Open is the most suspect...

[fickle nebula]

isnt it weird not executing something in the begin play?

[odd ember]

not sure what you mean by that?

that it doesn't find it at begin play?

[fickle nebula]

if I use a breakpoint on the cast to game instance, it wont stop

[odd ember]

I'm really not following

[fickle nebula]

ok with this node it worked

but now I need to delete stuff from the previous level

nvm, I'll try to work with a persistent level

[umbral galleon]

navigation raycast??

[dawn gazelle]

I came up with this...

[rough warren]

So, I spawn my "spawn_zone" actor bp after my building gen bp is spawned, and I created this to detect what "building gen bp's are colliding with my spawnzone and delete the ones that are" and it doesn't seem to do anything. Got any clue why?

[keen wedge]

Best "guess" would be that they are not deemed to be "overlapping", e.g. not in your array of things you're deleting.. throw a PRINT node in that Loop and spit out what's in it... alternatively, remove the "DestroyActor" node temporarily, and replace with a PRINT node, then append the name of the actor that is effectively going to be destroyed...

[rough warren]

Alright, so I threw in a print statement and it shows nothing.

[keen wedge]

So, either nothing in your array has that class... or, maybe there's nothing in the array...

you can use a LENGTH node to get the size of the array, try printing that out before you loop through... see what you have..

[mystic bough]

thanks, looks solid.

[keen wedge]

you might need to set your collider on that GetOverlappingActors node too... where it says "Self" etc... depending on your setup..

[keen wedge]

also.... check the collision presets to see that the objects/presets actually can cause overlap events with each other..

[rough warren]

outputs 0

so it's not detecting any collisions

[rough warren]

how can I do that?

in the collision tab right?

[keen wedge]

okey... so everything is set to "block"... not overlap..

[rough warren]

should I use custom or one of the presets

[keen wedge]

you could test with one of the presets first, but then you may want to create a custom one later, along with perhaps an object channel... try changing to OverlapAllDynamic and see what happens

you might get something in the PRINT

[rough warren]

right, changed both collisions and there is still a 0

[keen wedge]

did you set the GetOverlappingActors node to have a collision volume reference going into it, instead of Self?

e.g. the collision component

[rough warren]

I changed it to

[keen wedge]

Is this code running "inside" of the cube?

e.g. its the blueprint for that cube

[rough warren]

yeah

[keen wedge]

Is there a specific collision volume component on that cube?

[rough warren]

dont think so, I just added a component cube

[keen wedge]

Does it have "Generate Overlap Events" ticked on it?

[rough warren]

yup

[keen wedge]

...and what about whatever you're trying to collide with it?

is that set up the same?

[rough warren]

Yup

[keen wedge]

So BeginOverlap and GetOverlappingActors are not doing anything at all for you?

[rough warren]

Yeah

[keen wedge]

can you zip up the project? what version is it?

I'm running 4.26.2, will have a look if its quick...

[rough warren]

Wait, you said "BeginOverlap"

How do you mean by that

And the version is UE5 EA2

[keen wedge]

Yeah, there are events that you can add also... OnActorBeginOverlap and OnComponentBeginOverlap... its kinda hard to do this blind without knowing what you've got set up, how its set up, and whats going on...

I dont have that version installed I'm afraid..

https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Collision/OnActorBeginOverlap/
https://docs.unrealengine.com/4.26/en-US/BlueprintAPI/Collision/OnComponentBeginOverlap/

[rough warren]

Yeah that's all good. I'll take a look at these

Do I need to set this object as a trigger or is that not a thing in Unreal Egnine

[keen wedge]

Unity background?

[rough warren]

Yeah.

I like Unity, I understand it but I feel like Unreal is better for what I want to do.

[keen wedge]

From memory, there were triggers and colliders weren't there? UE has overlap/hit...

[rough warren]

Yeah triggers and colliders

[keen wedge]

so the triggers are your overlaps..

the colliders are the hit caused by something being blocked

[rough warren]

so I just tried this out, and it's not outputting. Something is wrong with my colliders and I'm gonna just delete them and work from scratch on em

[keen wedge]

I would try adding a specific collision volume to your blueprint... and then test against that specific componet...
I'm gunna have to call it a night now... its 03:43 here and I'm exhausted..

[rough warren]

Yikes, all good

[keen wedge]

Take a look at this... the overview may get you started:
https://docs.unrealengine.com/4.27/en-US/InteractiveExperiences/Physics/Collision/

...and then the How To takes you through in small steps 🙂

[rough warren]

Sounds good, thanks for the help!

[keen wedge]

No problem, sorry we didn't get it sorted for you... gotta go... good luck 🙂

[rough warren]

Thanks! Bye

[trim matrix]

how come in gamestate it's not letting me do the reference with the dropper thing? if I put this in the level BP it will let me.

[dark crow]

Cause Level BP has access to Actors in the Level

[trim matrix]

ok

anyway I can create a reference in gamestate?

[dark crow]

Depends what you need

[trim matrix]

I need access to an actor in the level

[dark crow]

Is there only one of that type or many?

[trim matrix]

one

should I get actors of class?

[dark crow]

Get Actor Of Class would be the easiest way

[trim matrix]

aiight

thank you

[dark crow]

There's a version that only returns the first Actor which sounds like your case

[trim matrix]

gotcha

thank you again man

it worked

this has been bothering me for a bit but you helped bunches. I appreciate it a lot. Thank you very much!!!!

[faint pasture]

Is it bad form to extend static mesh component? I have a gameplay-related scene component that is always combod with a static mesh. Is extending static mesh fine for this (basically making a mesh + gameplay functionality) or does that smell?

Like say you were making a WingComponent for aerodynamics. Would it be bad form to have the parent class of WingComponent be StaticMeshComponent?

[brazen merlin]

ill give you permission if it makes you feel better about it

[faint pasture]

I mean does it feel gross? It kinda feels gross.

I'm already 3 layers deep into my modular vehicle system tho, I don't wanna make a PowerPort an actor

It'd be Vehicle has Engine has Powerport (has power port component?)

It's stuff like this that makes me wish we had Godot style scenes

[brazen merlin]

well we extend actor class and have visuals + code

would do the same for actor component... so then if staticmeshcomp has everything you want anyways...

[rough cedar]

Just wondering if anyone has a good system to swap weapons and play a specific character animation and weapon animation but both of them are triggered from a single montage. Is this possible? Right now I’m just playing both animations simultaneously but that kinda messes up my combat system. Any help or link to a good tutorial is much appreciated!

[wild seal]

how can i implement the intarface in bp?

i inherited it right click the function implement

event appeared i did print and nothing happens when i call the function

[faint pasture]

Show what you have. Show how you're calling it

[wild seal]

did it only in c++ so far

thought it should be working 🤷‍♀️

sooo any insights? why this could happen?

[brazen merlin]

id help but i dunno cpp >.<

[wild seal]

rhis is the class settings

keeping it simple as possible

[brazen merlin]

from a bp standpoint, there's a caller and receiver, I see above that the event call is for the receiver, if the code below that is for the caller then it should fire and be received. Regarding the caller (at least for bp setup) the call to the bpi needs the target as a reference (the receiver)

[wild seal]

ok so the thing is

this is how i call it

and the cast is not working i assume because i add the interface in BP

:/

[brazen merlin]

as mentioned, i dont do cpp, but i dont see any reference to the target - casting to the interface is not a target, it should be some actor

like talking between the player and a light switch or something

[verbal current]

Trying to figure out how to pass along a variable (location vector) from a blueprint that contains an actor, that spawns another actor from a blueprint.

To give an example. Think a house that is spawning an npc. I want that NPC to be able to know the location of the house that spawned it. I was thinking I could maybe link the two by using the Owner tag in SpawnActor to then somehow reference the owner in the blueprint of the spawned actor. But after some googling I'm not sure that's what that does. Could anyone point me in a good direction to look/read?

I'd like to be able to reference the "Villager Spawn location" from inside the villager NPC blueprint.

[wild seal]

the target is the act, i assume

[brazen merlin]

you need to have a variable for this location to exist on the class you are spawning. Then you can set that var with the one you have here. Or you can have the spawned class get it's location at spawn and set it because that's essentially the same location

[brazen merlin]

i think the cast is wrong but i dont know cpp, try #cpp

[wild seal]

yeah works in cpp, but apparently have to work differently when i wanna use bps

[brazen merlin]

i only do bp so i can help there, but im lost with the hybrid use of the two

[verbal current]

Thank you! So I did have that, what I was struggling with is figuring out how to set the variable in the class that i'm using as the spawn target. I was thinking maybe the getOwner function but it returns an object and I wasn't sure how to get the variable out of it.

And yes you're right I could use the current location at spawn as well. But I'm hoping to make this a generic villager class I can attach to many different things that spawn it. I figured it would be smarter to "attach" it to the BP that spawns it.

[brazen merlin]

well since you are playing with options, just know that there is a return value of the spawn actor node which is what you just spawned. So there is plenty you can do at that point

[faint pasture]

After spawning the villager, have the spawner set VillagerSpawnLocation

it'll have a ref to the villager and its spawn location by definition

[verbal current]

I believe I've already done that before even actually spawning it, that's the SET that then pipes into the spawn transform location. What I'm trying to get is the spawned actor to pull a variable from the actor that spawned it.

BUT as @brazen merlin said, I think if I just pulled it's current location right as it spawns it shouldn't really matter... I think I was just overthinking it.

[faint pasture]

Then just set MySpawnerActor ref or whatever

[verbal current]

The return value of the spawn actor node last bit I don't quite understand though. But I figure in the future it would be good to know how to get info from the spawning BP anyways.

[faint pasture]

Spawn Villager -> Set MySpawner on the villager that just spawned to Self

[faint pasture]

That return value is a reference to the spawned actor

[verbal current]

OH... I think I get it. 1 sec

like this. Cuz i'm getting the spawned object as a return value like @brazen merlin said, I have a link and that'll fill the value at the other end. That totally makes sense. Thank you both!

[rough warren]

I'm still unable to figure out why my "spawn_zone" bp cannot detect these "building_gen" points. It can detect a player but it's unable to detect the small little cubes. (the big cube is my spawn zone and all the small cubes are my building gens

[verbal current]

hmmn, wait shit. I just tried that, and while it picked up the variable "spawn location" that exists in the villager blueprint in the set function at the end, when I tried to compile I get this error because that variable doesn't exist in the spawnning bp/actor. (which in this case is the well)

[faint pasture]

Show the collision settings for both boxes

[faint pasture]

Recreate that set node. Drag off the spawn villager return value and set the spawn location

does Villager have a variable SpawnLocation?

[verbal current]

yes it does.

I'll try remaking it.

[rough warren]

(this is spawn_zone)

(this is building_gen)

[verbal current]

huh... werid. it works when i remade it. But it looks identical to the one that errored out.

[faint pasture]

Yeah it mighta been stuck trying to set some variable with the same name or maybe you changed the spawn actor class after making it or whatever.

why are you storing VillagerSpawnLocation tho

[brazen merlin]

id guess that the error was because it was not compiled if the variable was made on this spawned class

[verbal current]

Gotcha. In any case that helps me understand that a lot better. Thank you again.

I want to set a patrol from it's spawn point to a central "village hall" actor on the map.

So I wanted to have the starting and ending vectors to make it walk back and forth.

[verbal current]

Yeah I think I hadn't compiled it on the villager class.

[brazen merlin]

nvm, it says it could not not find it in Well_BP, so its the wrong set node

[verbal current]

It's been years since I did any real CS. can't believe I didn't catch that return value. Makes total sense now.

[faint pasture]

I would just set spawn location on begin play. It'll by definition be where it is when begin play fires.

Then it's dummy proof, don't gotta remember to set it

[verbal current]

Yeah, when conrad mentioned that I realized I was overthinking it. But It's a good lesson learned for next time I do need to pass along some sort of variable.

I want to have several different classes spawning the same villager class. and they all remember their individual spawn locations is why. But yeah no reason they just can't check at spawn time.

[rough warren]

yeah it's weird, it doesn't register anything else except the player

[rough warren]

Okay, I tested moving the piece and it works, it just doesn't work when it's spawned into the zone

Does anyone know a way around this?

Nvm, all good did something and fixed it

[dusk dust]

Yet again asking for someone to try and help me understand this

Please let me know if I need to elaborate

[rough cedar]

anyone know of an easy way to set visibility of a mesh on a certain frame of a montage.

[fiery swallow]

anim notify

[rough cedar]

Ok cool thats what I was thinking

[gentle urchin]

I shared a snippet for that yesterday

[gentle urchin]

This

[torn kettle]

:no_entry_sign: Slygear#8224 was banned.

[hardy sphinx]

i need object to move to a player, but it goes to falls locations and idk why. maybe smb understand why?

[zealous fog]

Is there a reason you aren't using the ai move to node?

[hardy sphinx]

but its a static mesh

[zealous fog]

What's the parent class? Does it have character moving component?

No idea what yoy are trying to do, right now you're only storing a reference to the class

[dusk dust]

I really don't know why this isn't working

I've tested it without procedural mesh component and it works fine

I've also just called the create grid function once without a forloop and built the mesh, and I was able to move it around

[fiery swallow]

@zealous fog love the pfp

[rough cedar]

Is there a way to create a timer within an anim notify blueprint?

[quaint nova]

Hey. I have the 2d paper template and I would like some help on the character moving to a direction when the level loads and I couldn't find any tutorials

[zealous fog]

You'll all have to give some more explanation about your problem, what you've tried to do to solve it, what you are trying to do exactly and preferably show the BPs

[zealous fog]

Haha thanks!

[quaint nova]

This is the BP and I tried Unreal's own tutorial on the endless runner (customizing it to 2d https://www.youtube.com/watch?v=yS-yQfo0lc0&t=254s

[zealous fog]

You dont need the branches

Or you need to know what side he is moving for another function?

You are moving btw just really slowly

Try increasing world direction

Scale only goes from -1 to 1

You dont need the second branch at all anyways

You can just plug it into the set bool

[quaint nova]

i figured it out myself

[gentle urchin]

Not the first one either

[quaint nova]

somehow

[zealous fog]

Depends on if he needs to know if the character is moving right

[gentle urchin]

Not really

Bool == axis > 0

No branching needed

[worthy carbon]

Hi! I created an inventory but when i pick up the weapon it doesn’t attach to the player… someone help me

[gentle urchin]

Branchless logic 😄

[zealous fog]

Oh how do you set that up?

[gentle urchin]

Set the bool directly based on the condition

Just ditch the branch and plug the condition result into the bool

[zealous fog]

Oh yeah that's true

Does it matter much? Besides looking prettier

Performance wise

[gentle urchin]

Not anything you'll notice

But branching is error prone

Theres always an extra possibility for mistakes when you branch

[zealous fog]

Fair point

[zealous fog]

Have you debugged it? Where is it going wrong?

[worthy carbon]

Not yet

[jolly island]

Hello, does anyone know why Simple Move To Actor works for moving my player character but Ai Move To doesn't? The Ai node would be more useful.

[zealous fog]

Then do that first

[worthy carbon]

👍🏻

[zealous fog]

Does it have an AI controller? I think you need one

[jolly island]

It says that Ai controller class is AIController in class defaults under pawn.

[zealous fog]

Show the BPs

[jolly island]

There's a Set AiController Class node, mayb that would work? Never used it myself.

[zealous fog]

Class defaults or class settings

[zealous fog]

It has an ai controller in the setting, but I assume you posses it during play? Because then it has player controller I believe

[jolly island]

Oh, I see. So you can't use that node for player character then?

[zealous fog]

Not if its possessed by the player I think

What are you trying to make

[jolly island]

I just need to have the player move to an actor when clicked on and I need to know when the movement is complete so it's at a certain distance from the actor

[zealous fog]

Top down game? You can just have the "player" be an AI if you wanna do AI stuff with it

But maybe you can just get the distance between the 2 and then stop the character from moving when too close?

Yes, you're asking if the directions are equal however that's a really small margin

You should instead get the direction and add a margin to it, and ask if the rotations are within that margin

You're asking the thing on the left

One really specific rotation

You should ask on the right, if my rotation within this range

0 is one rotation, x is another, find out if y degrees is between 0 and x

And this is 2d btw

So depending on what you wanna do, you also have to solve for the z axis, or you can decided to break the rotation and only use the x and y axis

No scrap that

Brain fairt

This is just for one axus

The z axis

If you wanna do it in 3d you'd have to solve for 2 or 3 axis

So I would keep it to the z axis for simplicity

Have you googled it

[jolly island]

I'll have to try that then, thanks 🙂

Or would it be possible to turn the player into an AI temporarily?

[cursive path]

Hi i have problem with world composition when loading and unloading tge level there is little lag is there any fix for it??

[zealous fog]

Probably yes

You'd have to look it up

I dont know how but I imagine it should be a pretty normal feature for an engine

[trim matrix]

Hey there, I have this delegate here (which took me a long time to figure out cus I did it in c++), what do I do now to broadcast this to my animbp?

[odd ember]

how...

and maybe.... why?

delegates broadcast to their subscribers, so your animBP needs to subscribe to your delegate

[trim matrix]

Ah okay

Sorry but do you have any idea how?

[odd ember]

well if you know how to make a delegate, how do you not know how they work?!

event dispatcher is the name used in BP

the functionality for adding subscriptions is Assign or Bind

[mortal wharf]

I have this USTRUCT:

 USTRUCT(BlueprintType)
struct GAME_API FSSPInventory
{
    GENERATED_BODY()

     UPROPERTY(EditAnywhere, BlueprintReadWrite)
    TArray<AEquipment*> Equipments;
};

But in blueprint, I can't access the Equipments TArray. How come?

[odd ember]

#cpp

[mortal wharf]

You want me to post in #cpp ? Alright 🙂

[odd ember]

yes it's nothing to do with BP

[lost crow]

Hello guys, I added mobile input to the screen, but when it is damaged by AI, all touch is gone. Anyone know the reason for this?

[odd ember]

ask in #mobile perhaps?

[lost crow]

oh sorry. My bad, im new on here

[devout dove]

I'm trying to open a level but it won't, so I have created a Menu that opens a "Town" level when pressed on "play" and then in that "Town" i have a button saying "Fly" so if pressed another level should open but it doesn't. It weirdly moves me into some random place in town.

Here is the town

When i click on Fly i see this

Found the issue, "BlockAll" collision caused this problem.

[sinful moth]

Can anyone explain what the delegate means in the last block?

[earnest tangle]

It's an event that gets called when the ai is spawned

The node is perhaps asynchronous

Hard to say for sure because that doesn't look like a default UE node but rather from some plugin

[primal smelt]

The spawner delegate node is just a custom event, any code you put on that exec line will fire off. As zomg pointed out, looks like it will do so when the actor is spawned

[subtle isle]

Oh I feel like I was asking my questions in the wrong place so I'll repost it here and delete it from where I just wrote it

Hey, I'm trying to figure out how to make it so if a player presses a key while in a specific area (trigger zone) it transports him elsewhere but I am unable to call the inputaction to the BP where my triggerzone is
I have this set up as my interact event right now for testing

and nothing shows up when I look it up through my reference

[hexed glade]

Is there a better way to retrieve variables from a character than using cast to? I ran in to problems with using cast to when switching characters.

[sinful moth]

Alright thanks

[sinful moth]

Yeah it's a custom engine for making mods for a game

[last abyss]

you should look into interfaces

[odd ember]

cast to their parent

[hexed glade]

Ah, yeah that would work.

[primal smelt]

I'm not familiar with the particulars of Launch Character node, but in the trigger bp (or level bp) you should be able to get the character reference from the trigger and you could set a bool from there called "overlapping" or something like that. Then you could put a branch infront of that Launch CHaracter node checking this value.

[subtle isle]

I wont be using the launch character node, it was more for testing purposes so I suppose i can switch it to a print node instead

[primal smelt]

You'd need to return false to the value when the character is no longer overlapping

[subtle isle]

Ill give that a go real quick

Lets see if I can pull that off without my brain exploding this late at night, thank you!

[odd ember]

you should be using the OtherActor pin instead of trying to get player character

[subtle isle]

otheractor?

ahh

[odd ember]

you have two separate problems essentially: registering that the player is in a specific place, and whether a player has pressed a specific button

[subtle isle]

like so?

[odd ember]

yes

so that will check all actors that pass through

but only if they are of the class you are casting to they will pass through

how you do the next part is a bit more finicky

if you have interaction in your game across the board, I recommend thinking of system for interaction where objects/actors in the world register themselves to the player, and based on some conditions that you can set up, the player interacts with what you want

[subtle isle]

to be very honest I don't have many systems right now, its a pretty empty project
I am doing this for a class project and we don't have to make a whole game just a working level

[odd ember]

in that case

[odd ember]

you can make it so you just register a single actor at a time

[subtle isle]

I would be doing this in my Character blueprint or my object blueprint?

[odd ember]

ideally in the controller, but character in your case will do

[subtle isle]

this is the triggerzone i was talking about

[odd ember]

yeah that's fine

it doesn't matter

basically your registration code is what matters

and that's in the character

[subtle isle]

alright

[odd ember]

for simplicity's sake, it's worth implementing an interface for this

[subtle isle]

yesss! An interface, I was trying to get that to work

[primal smelt]

The quick and dirty approach (what I mostly know) would be that branch method. From the cast BP you could pull off the As BP Skjorn (presuming that's the player character) to set the bool. You need to create the bool variable and compile it in your character bp first though

[odd ember]

then create a variable of that interface inside your player character

[subtle isle]

I have one called Enter

[odd ember]

okay what you want is an interaction interface that has a Use function

have you setup inputs in your project for a Use key?

[subtle isle]

Im assuming this

[odd ember]

perfect

yeah so do you have event setup in your player character BP?

[subtle isle]

nope, thats where I got lost

I made a BPI_Interact

and added the interface to my character BP

[odd ember]

you don't need to add it to you character

you add it to the objects you want to interact with

[subtle isle]

right

I had also added it to the cave from earlier

[odd ember]

so look for InputAction inside your player character

you should have one for Interact

[subtle isle]

oh right

[odd ember]

bingo

next, create a variable for your BPI_Interact inside your character

just a variable

[subtle isle]

can I call it interact?

[odd ember]

call it something like CurrentInteraction

[subtle isle]

like this ?

[odd ember]

yep

[subtle isle]

never made a bpi var b4

[odd ember]

crazy innit

[subtle isle]

yea crazy xD

[odd ember]

so now off of your Interact action, get the variable of your BPI_Interact and drag out a pin to the Use function

[vernal path]

Hi all, in a chess example... if i want to change the piece colour to yellow (selected) and later (after deselction) back to default colour. Function Vs Custom Event, which one to prefer and why?

[odd ember]

functions have return values and are expected to return instantly

events can do whatever you want, including delayed/timed functionality, but cannot have return values

[subtle isle]

is this what you mean by getting the BPI_Interact variable?

feel like im setting it rn

[odd ember]

nope. open your BPI_Interact

create a function called Use

[subtle isle]

ooh

[vernal path]

right.. i read that... like in this case, anything will work right.. should i prefer function or event?

[odd ember]

you have to make your own considerations. I don't know your use case

[subtle isle]

like this ey?

[odd ember]

correct

[subtle isle]

awesome

[odd ember]

now

go back into your object

that you want to interact with

add the interact interface if you haven't already

[subtle isle]

donezo

[odd ember]

then where we were with the cast node

[subtle isle]

(also making it show some text)

[odd ember]

you want to pull the character BP's pin and use it to Set CurrentInteraction to Self

[subtle isle]

self as in the cave's triggerzone?

[odd ember]

yes

[odd ember]

get a reference to self

type self or this inside the context menu

add it to the yellow pin

[subtle isle]

ah got it

[odd ember]

cast it

[subtle isle]

like this?

[odd ember]

correct

[subtle isle]

am i casting it to the right thing xD?

[odd ember]

well

probably not?

you need to cast it to the interface

[subtle isle]

ohh there ya go

[odd ember]

yes

and connect it

so now there's two things left to do

[odd ember]

1. Implement the Use function on the object itself

[gentle urchin]

Isnt this over the top? 😅

Couldnt it just be an actor reference ?

[odd ember]

2. Make sure that when the player leaves the object's area it zero's out the interaction

[gentle urchin]

Instead of bpi reference?

[odd ember]

no it couldn't

[gentle urchin]

How so

[odd ember]

because you don't know what the object needs to be that you want to interact with

[subtle isle]

i have the node ready

[odd ember]

yep so remember to cast again

you only want it to happen if it's the player character

[odd ember]

null it out

as in, set it to nothing

[gentle urchin]

Object in this context would always have to be an actor, wouldnt it ? Placed in the world..

[odd ember]

not all actors can be interacted with

[subtle isle]

how do ya set it to nothing?

[odd ember]

leave the pin empty

[gentle urchin]

No, but those wouldnt set themself to the interactable actor

[subtle isle]

oh

so the way it is now?

[gentle urchin]

And even if they did , it wouldnt react to the interface message due to no implementation

[odd ember]

you could not register the interaction functionality without the interface in this case

so yes, the interface is necessary

is this the most optimal way of doing things? probably not. but it's a quick and dirty way to get it working well

[gentle urchin]

Guess theres something im not seeing in this scenario then

True

[subtle isle]

am i to remove the target?

like that?

[odd ember]

have you read the entire thread? literally we're using the interface calls to ensure that we can use the interface. if we didn't have the interface, what would be called on the actor?

[odd ember]

no, remove the yellow pin

[subtle isle]

oh right right

[odd ember]

Target should be your player character

[subtle isle]

should be good now

[odd ember]

yes

it's not super clean but it'll do

next

implement the Use function

[subtle isle]

that's all we need brother

[odd ember]

and just do whatever you want to do on that function basically

[subtle isle]

message?

[odd ember]

no

in the panel do you have a Use function?

[subtle isle]

under functions?

[odd ember]

yes

double click it

that's where your interaction logic goes

[subtle isle]

oh boy

one second

[odd ember]

did you implement the interface?

[subtle isle]

just did now :X

[odd ember]

yep

[odd ember]

no

[subtle isle]

aight

[odd ember]

that would imply using it as soon as you enter it

implement it as an event or function

[subtle isle]

that clears things up

[odd ember]

and add the logic you want to have happen onto it

[subtle isle]

i get it from here i reckon

[odd ember]

just right click on the Use function

and click Implement

[odd ember]

👏

this is where your interaction logic goes

whatever you want

[subtle isle]

and here I would put in what would happen

wonderful

and its only being called because of this part right?

[odd ember]

yes. we're registering the interaction to be current

because that's where the player is

it's not perfect

it doesn't account for a lot of cases

but for a simple project it'll do fine

you can do the same type of logic for any number of actors or objects and they'll work all the same, as long as they implement the interface and add themselves as a current interaction

[subtle isle]

it workeeeed

[odd ember]

well duh

[subtle isle]

genius

this anything i should worry about?

[odd ember]

yes

put an IsValid before the Use call to the CurrentInteraction in your character BP

[odd ember]

👍

wait no

[gentle urchin]

Mesh?

Nah

[odd ember]

the current interaction

is what you're checking for

[subtle isle]

oh

reference to self?

[gentle urchin]

Intefaces dont throw errors for nullpts afaik

[odd ember]

no

it will since it's a variable

[gentle urchin]

Mine doesnt 🤷‍♂️

[odd ember]

a call won't trigger a nullptr

but if you have a pointer to an object, then that pointer can be null, whether it implements an interface or not

[subtle isle]

what does reference to self call in the bp for the character?

[odd ember]

forget reference to self

[subtle isle]

aight
