So maybe you play the locomotion blendspace based on velocity, then play Jumping if going up, and play Falling if going down.

3 pose sources and 2 blends

[midnight blaze]

I've already identified a number of points where I disagree with things like naming scheme but these are all really, really simple teaching examples, which is what I need at the moment. I started on some videos intended to be an introduction but it was all... high-level abstract and historical information and not touching the tools in the detail that I need to actually learn it

[faint pasture]

Does this use a state machine or just blends?

[midnight blaze]

State machine

[faint pasture]

Ya so you'd have 3 states and the rules to transition would depend on those 2 bools. You'll figure it out.

[midnight blaze]

Yeah, I understand that part, but I don't know what I don't know. Never touched animation before this in... anything. I think I watched a video on how it's done in Flash once.

[faint pasture]

I'd take a peek at the 3rd person template if you haven't yet. It's got a nice simple animBP

[midnight blaze]

I'll go back to that one and see what it does after this one

I was really just wondering if there was some weird pitfall with something like the vertical component changing between the sequence executions and the value of the last getVelocity persistng somehow

[faint pasture]

For reference I'd do running and jumping as 2 states with 2 blend spaces. Running blendspace uses velocity to blend between running and standing, and jumping blendspace uses Z velocity to blend between jumping and falling.

[midnight blaze]

Ah, neat

[faint pasture]

bIsInAir would be the bool to switch them, I think you can just yoink it from the character movement component but don't quote me. My game doesn't have jumping shrug

actually i think its called IsFalling

Anyway anyone here ever done a detached camera? What's the most elegent solution?

If I could jsut add a camera component to the playercontroller and drive it around that'd be great but that doesn't seem to work.

[final python]

I am working on a project with a bunch of idiots that just sit on their phones and stuff, anyways, the yellow arrow indicates the tick in the base enemy class and everything in the picture is connected to it. I am pretty sure this is waaaaaaaaaaaay to much, especially considering there are gonna be about 25 - 75 enemies spawned at once. I have told them use timelines and timers, but their best solution is the easy way and throw everything onto the tick.

(everything except that one event in the middle) nevermind it is binded

[faint pasture]

" bunch of idiots" correct

not that tick is bad

but

why not do AI with the AI systems

That's a clusterfuck, what all is going on there?

[final python]

idk, and that is just the base enemy as well, the others call the parent plus a shit load more

[faint pasture]

Yes you guys need to learn Behavior Trees if you want decent AI that's not a spaghetti mess

[final python]

idk isnt for what all is going on there, let me look real fast

[faint pasture]

Can you give a higher res screenshot so I can see what's going on here?

[final python]

moving left to right it does ai stuff along with setting flipbooks, then in the middle it does damage checking and health checking along with flipbooks, then at the right it does more movement things.

[faint pasture]

Do you have smoothly regenerating health?

[final python]

no the health doesn't regen on the enemies

[faint pasture]

Then probably none of that has to be on tick. Dunno much about flipbooks but they might have to be

[final python]

I mean this project is a cluster fuck. I have 1 thing on tick, which I am working on the bosses, and it checks death and thats it

[faint pasture]

Basically if you don't expect something to be changing EVERY FRAME, it doesn't need to be on tick

not even that has to be, just make an Event Death

[foggy escarp]

@final python https://www.unrealengine.com/marketplace/en-US/product/graph-printer?sessionInvalidated=true
You'll thank me later

[faint pasture]

Event any damage -> is hp<=0? -> Event Death

[final python]

yea would be nice if I could do it that way

[faint pasture]

This project is headed to chugga chugga spaghetti city if you guys don't whip it into shape lmao

[final python]

but the character guy who also does the projectiles is half dumb as well

oh trust me it already is there lmao

[faint pasture]

Start with this. If it doesn't typically change a value EVERY FRAME, it doesn't go on tick.

HP Regen on tick is fine

updating aim direction on tick is fine

animation stuff that should probably be in the animBP but can be hacked together in the pawn BP is fine

checking for Dead is not

For instance, here's my Character tick, where I do stuff that has to update EVERY FRAME

the acceleration tilt can probably be handled by animation, just haven't don that yet

[final python]

yea I know tick, im saying there is about 15 of us in this class working on this project, and about 10 of them either sleep, sit on their phones, or gossip the entire class (and all classes), and the only reason I had to check death on tick was because he wasn't applying damage on the enemy attacks, he was straight subtracting health

[faint pasture]

If you're trying to do AI in your Character BP by doing stuff like perception or navigation ON TICK with 70+ AI running around is a recipe for disaster.

lmao

when's this due?

[final python]

we also have a c++ class that is another project class, but it is solo since we are still in the process of learning it, and they do the same thing in there, so Idk how their projects are gonna turn out onthat

the next milestone is due monday lmao, but its graded on seperate parts so I am good

like they get graded on what they wroked on, and I get graded on what I worked on, and so on

[faint pasture]

Set your HP variable private

[final python]

yea, this is a mess, me and about 3 other people are trying to get everything to semi work, because also a bigger kicker is they said the enemies work and they dont at all, so we are gonna try to just polish it, since there isn't enough time to just do it ourselves

[faint pasture]

make him use the damage interface

yah 15 nubs on a BP project lmao consider yourself lucky if it doesn't crash

[final python]

yea I hope it doesn't, the professor is gonna be cringing once they see how much they have on the tick when we upload it, and present it lmao

[faint pasture]

So does like every pawn use different stuff if made by different people?

Is this fine or shitty?

For just driving around a camera as a transform.

[final python]

nah, like we split into groups, and then each group had 1 person create the base class, adn they all help out and think of stuff they needed to make it and include as much as possible that everyone needs (if needed) and send it to a branch on the github, and then they were assigned who would do what in that group, like you make enemy A, you make enemy B, you make enemy C, etc... , and they would all just work on their class, and communicate if they needed something added in another class, so 2 people wouldn't upload the same file and erase the other one, anyways, so to answer the question, sorta, but they all derive from a parent that they all made

[hexed inlet]

Would anyone know why GetActorOfClass fails (returns 'None') when the class it is getting an actor of simply has one component's collision enabled?

If I disable that component's collision, GetActorOfClass works again.

Ie, this:

... fixes/breaks this:

(Where that white egg/orange cone thing is the BP_Flyer)

[faint pasture]

Is the flyer spawning at runtime or does it already exist on the map?

[hexed inlet]

Runtime, it's the default Pawn class so PlayerStart sets its position

er

Well I guess that's not runtime

It's what the gamemode sets as the default pawn anyway

[tiny bay]

Did Unreal Engine 5 completely overhaul math operations?

I remember being able to do operations between different variables, but it seems to be unified and more limited?

for example, I used to be able to do intPoint - Float, but now it's gone, and it's giving me errors if I try to convert it into IntPoint

is there a way to get around this?

[sharp rapids]

I managed to get this
It's a lot wonky though, getting the widget to clamp exactly to the edges is a little bit tricky
The circle one is easier, but I reckon that's not what you want

Also, I suck at recording videos 🤷‍♂️

[brazen merlin]

square version looks better to me, close to skyrim level

[tight schooner]

@hexed inlet by description that's not a problem I've encountered. There must be some other logic involved. As a generic potential fix, try delaying the Get slightly in case it's some funky issue with the dynamically spawned thing not yet being fully constructed. Idk what the circumstances are.

Love the avatar btw. Star Control II is a personal fave.

[supple bane]

How do I do something while a delay is playing

?

[brazen merlin]

vague, but, Sequence?

[paper galleon]

I don't think that would work. Sequence does not allow parallel execution

[supple bane]

basically I want to continue on the the Meleeattack2 Bool without waiting for the delay

But I dont think its possible

atleast not the way Im doing it

[brazen merlin]

you're right, timer would work though

[supple bane]

timer?

[paper galleon]

Oh, right. Timer would work better

[paper galleon]

You set a timer for the event to fire after your set time. You'd need another event to hold the logic you want to run after the event.

Just get the timer node, it should be intuitive after that

Specifically timer by event. It's easier to work with imo, than timer by function name

[supple bane]

set timer by event?

Im not sure If this will work

Im trying to start a function and play it onTick, then stop it after a certain amount of time

will I just need to create a function to stop the original function

?

[paper galleon]

It's not recommended in any case to put a delay in tick.

[supple bane]

does a delay work not in tick?

[paper galleon]

It works. But you have to be careful in its useage. If you aren't sure of what you're doing, you'd get unexpected behaviour.

[supple bane]

Is there a way to make a function repeat every tick?

[paper galleon]

Tick

[supple bane]

besides just putting it in event tick

[paper galleon]

A looping timer.

[brazen merlin]

Timers!

If you can grasp them, they are the best alternative to delays

[supple bane]

Is there any way I can put a delay inside a function?

[brazen merlin]

no, event graph only 😛

[supple bane]

timres it is

[brazen merlin]

and yes you can put a timer in a function

a timer can call an event (via delegate or create event node) or a function (by its name)

[supple bane]

for a timer I just call it once, or do I call it at the end aswell?

[brazen merlin]

when you call the timer it sets it into action, it will wait the time before it calls the associated event/function

[supple bane]

alright

[paper galleon]

But your design sounds a bit suspicious. Tick without using tick? Are you trying to circumvent the notion that tick is bad?

[supple bane]

me?

[paper galleon]

Yep

[supple bane]

No I was just wondering because I know you need a tick to use a delay. So I was asking if a function could use ticks

if that makes sense

because I wanted to put a delay in a function

[paper galleon]

You don't need tick to use delay. You just can't use it in a regular bp function. Only events in the event graph. Doesn't have to be tick

[supple bane]

hm

so a function just plays a function when the timer runs out? or plays the function until the timer runs out?

[brazen merlin]

it would not be the best to use tick with delay. A delay node, when called, will run its time and if it is called again, it will ignore the input (pretty sure it will not allow the flow to continue). Once it expires and continues the flow, it can be called again

[paper galleon]

It plays a function after the timer expires. Like an alarm or a stopwatch

[brazen merlin]

i think i understand you.. you call Function A which has Timer A, and when Timer A expires it will call Function B

[supple bane]

alright

[supple bane]

its only asking for one function, it this Function A or B?

[hexed inlet]

Awesome hehe. You know they've (as in Fred and Paul) have officially started on UQM2? One of their team of now 4 does a stream twice a week on its development. Super super early stages.
Regarding the GetActorOfClass, I even tried calling it every tick. Same issue.

[brazen merlin]

so when the timer expires, it will call THAT function, does that make more sense?

[supple bane]

yes

[brazen merlin]

regarding tick, and this is twofold, you can check the timer to loop, which will repeat the time delay and call the associated event/function at each interval - secondarily, timers output their "handle" which is a reference to them so you can clear it, pause it, or check the time of it

[supple bane]

thanks

[paper galleon]

I think it'll be easier if you explain what you're trying to do. Not the logic, just what you want to achieve gameplay wise

[supple bane]

alright its gonna be a long explaination

[brazen merlin]

i remember the same difficulties and confusions, but if you can get the hang of them, they're awesome

[paper galleon]

Not the entire gameplay though 😅. Just the section that is troubling you

[supple bane]

I have a boss with two 'heads'. Each with two attacks. I need to be able to call and play any of the two attacks for a certain amount of time(which was what the delay was for)

[paper galleon]

So you play the attacks and after a while they stop?

[supple bane]

yes

I think I have a solution

I put a timer in each attack function, which plays a function stopping every attack and calling a random one again

But that wont work

now that I think about it

[paper galleon]

What kind of attacks are they?

Continuous?

[supple bane]

Depends on the attack

some repeat until they finish the timer, others continuous

[paper galleon]

Hmm, it's a complex case. I can't provide a design since I don't know the full picture. But I would suggest learning how to use timers they would be very useful for what I think you want to do.
And don't put delays in tick unless you've thought long and hard about it.

[supple bane]

lol thanks

But I have one last question

Can you put a timer for functionA if the timer is in functionA?

so it can call itself?

[brazen merlin]

nope

[paper galleon]

Not sure if you can but if it's possible I would advise against it. Recursive functions are usually a bad idea in most cases.

[supple bane]

But I can have timer for functionB in functionA?

[paper galleon]

Absolutely

[supple bane]

alright

thanks so much for the help

and gn/gm

[brazen merlin]

if it helps

CallThisWhenTimerExpires can be your function instead

[supple bane]

omg yes

tysm

[brazen merlin]

sure thing

[tiny bay]

would vector2d * float be the same as vetor2d (x) * float, vector2d(y) * float?

[supple bane]

so this should work?

[brazen merlin]

once E is pressed, 5 seconds later MeleeAttack1 will be called

[supple bane]

what if meleeattack1 relies on a tick?

[brazen merlin]

why does it rely on tick?

[timber knoll]

Yes

The * will basically do component based multiplication

[timber knoll]

Then it should use a timeline

So you trigeer the event and the event starts a timeline

[brazen merlin]

hmm, the only thing that is dependant on continuous updating is the set world location part

[timber knoll]

But that looks weird to me for a melee attack tho

[supple bane]

yes

[brazen merlin]

Delta Seconds * 0 !?

[timber knoll]

Yeah that just teleports them

[supple bane]

hm

[timber knoll]

You’re not even using the lerp

[supple bane]

idk how that got there

oh

I deleted the old float that went there

[brazen merlin]

ah ok

[supple bane]

wait no

thats 8.0

[timber knoll]

What are you lerping tho 🤔

An enemy position on melee attack

[brazen merlin]

is it? squints

[supple bane]

the boss goes from its current position of the player

[timber knoll]

Is that a part of the enemy?

Aah

[supple bane]

well to the player's old position

[timber knoll]

Yeah I would use a timeline for that

[brazen merlin]

so what about move to location node?

or move to actor

i guess it would stop once it reaches them..

[timber knoll]

Does that work if its not pawn/character?

[supple bane]

my code?

[timber knoll]

What conrad said

[brazen merlin]

"move to" calls just need an AI controller

[timber knoll]

Ye that is true

[brazen merlin]

and navmesh

[supple bane]

the boss doesnt have an ai controller

[brazen merlin]

i kinda figured

so... what my initial thought was 🙂 make another timer for the set location

actually wait..

[supple bane]

then it would interfere with other melee attacks

[timber knoll]

Nah nah

[supple bane]

possibly

[timber knoll]

Timelines are the way to go in that case 😛

Gives you control over the movement and how it interpolates

You just change the lerp alpha to the timeline value

[brazen merlin]

you call MeleeAttack1, that should do the set visibilities afterwards, the timer can loop at whatever interval to call the set location portion

[timber knoll]

Another timer as in event?

[brazen merlin]

doesnt need another timer

[timber knoll]

But you said timer 😛

I’m confused as to what your solution looks like

[brazen merlin]

please hold

[supple bane]

So if I set timer by function name it will simply just play the function even if it's not included in the event graph?

[gentle urchin]

Timeline sounds about right ^^

Triggerd by some anim notify is what i'd do

[timber knoll]

I think so 🤔 I actually always use event timers haha

But if you are using timeline which you are

It should be event regardless

[supple bane]

alright

[gentle urchin]

Well tineline gives you nice curve control

Which timer doesnt

[timber knoll]

Timeline as in time graph I mean...

Not the node 😛

[supple bane]

im assuming a set timer cant be called in event tick?

[gentle urchin]

Time graph?

[gentle urchin]

You wouldnt do it on tick

Is it a teleport?

Rip. Then thats solid

Lerp.. isnt this prone to issues?

[timber knoll]

No I wouldn’t do that conrad

[gentle urchin]

Fluxing framerate?

[brazen merlin]

this is how its setup up with a tick

im not a fan either

[timber knoll]

That is a very risky setup

[brazen merlin]

but if its working with a tick, then that would be the adjustment

[supple bane]

wdym by risky?

[timber knoll]

Keep in mind the event timer only means it will AT LEAST take x seconds

[brazen merlin]

i would prefer something else as well

[timber knoll]

So if you drop fps

Your movement will be completly broken

Whereas normal frame tick is variable

[brazen merlin]

im assuming delta seconds is set by tick, meaning the delay time should match with the frame drop

[supple bane]

so a better aproach would be a timeline?

[timber knoll]

It won’t either

[gentle urchin]

Delta is, but timer isnt adjusted

[timber knoll]

You will have last frames time

[supple bane]

how would that look?

[brazen merlin]

a better approach for movement would be Move To, but there's no AI controller

[timber knoll]

Yeah or as we said a timeline

That 100% guarantees to not mess up

[gentle urchin]

MoveTo, isnt this some charge attack? Sry didnt read up to far 😅

[brazen merlin]

you say that...

[timber knoll]

It does tho

[brazen merlin]

there's no Ai controller

[supple bane]

no, just move to the players previous location

[timber knoll]

If your frame drops, your timeline will sinply continue and stop at the end

Guaranteed

[brazen merlin]

feel free to provide a mockup, there's a reason why BT and AI controller exist though

[timber knoll]

Yeye that would be a good idea

[gentle urchin]

Ahz, ok

[supple bane]

I might just have to restart the whole thing but with an ai controller this time 😭

[timber knoll]

But without, I think that would be the way to go

[brazen merlin]

what's the boss curently?

[gentle urchin]

If one is doing bp ai one could make a custom input management system for the ai without ai controller, but feels way out of scope for this

[supple bane]

It was fully functional except for one unfixeable bug

atleast unfixeable the way I made it originally

[brazen merlin]

you could always just not do this one thing and go a different route

before it becomes a topic of proper AI execution

[supple bane]

Id rather just restart and do it right this time

[timber knoll]

Give me 3min need to get onto my pc then xd

[gentle urchin]

Moving actor with set location will break animation walking tho

0 velocity

[brazen merlin]

i dont think its necessary anymore

[supple bane]

so whats so good about an ai controller?

[brazen merlin]

its just been a bit of bp, so honestly if noha says it mainly works except for this little detail, then i assume they have it implemented the way they want

[gentle urchin]

Fair enough

[brazen merlin]

once again noha, if it's just this one thing, maybe just cut this and work with what works currently

perhaps you'll have an opportunity to make another enemy and then you can explore ai controller method

[supple bane]

everything works, But I want to add more than just 2 attacks, but with the way I have it implemented it would just cause more problems, even if I remove the problematic attack alltogether, more problems would arise anyway

[brazen merlin]

it works with one attack but not two right?

[supple bane]

3 work, 1 doesnt

but its going to be nice having a fresh template

[brazen merlin]

https://tenor.com/view/jackie-chan-meme-what-confused-huh-gif-5480485

[timber knoll]

it is somewhat of a learning curve tho if you've never worked with AI controller and BT before

[supple bane]

thats alright

[brazen merlin]

i dont want you going down this route when this is essentially working

[supple bane]

heres how I put it in:

[brazen merlin]

if you want to do Ai, make a new class, implement this method as a new enemy rather than replacing what you have

separate it completely from what you have now in the same project

[supple bane]

this isnt going to be my last boss, so I might aswell learn how to do it right

and yes, I would completely restart

[timber knoll]

oh right... not your last one ye then sure

basically the BT will be the brain of your boss

[brazen merlin]

ehhh, dont go deleting all you got now

[timber knoll]

so you just feed it with data and it will do the work for you

well kind of for you, you tell it what action to do based on the data

[supple bane]

yea Im still keeping some code

[brazen merlin]

just dont mess with that code

since you want to start from scratch, just make new classes and such

[supple bane]

im talking about health mainly

[brazen merlin]

so am i

[supple bane]

oh

alright

[brazen merlin]

wait, enemy health or your health?

[timber knoll]

duplicate and remove the attack/movement code

[supple bane]

enemy

[brazen merlin]

alright, still, yeah

[supple bane]

how does an ai controller work?

[timber knoll]

similar to a playercontroller for the player

[brazen merlin]

you have functions that it can call such as move to actor which does what i think you were trying to do with the set actor location

[timber knoll]

but then every AI has it's own controller with the basic AI functionality

[brazen merlin]

it does use navigation mesh

[supple bane]

so it will make life easier or harder?

[timber knoll]

easier to maintain, harder to set up right since you're new to it 😄

[brazen merlin]

https://tenor.com/view/idk-nickofferman-gif-5026658

i think it best to jump into some how to AI vids

[supple bane]

yea thats a good idea

ill start in the morning

thanks

and gn

[brazen merlin]

good luck

[supple bane]

ty

[timber knoll]

https://www.youtube.com/watch?v=iY1jnFvHgbE

here you have a good starting point explaining some of the basics as well 🙂

gn

[brazen merlin]

that is a great one, might be steep

that is actually one of the best ones compared to most other BT AI tutorials

[supple bane]

so even with a BT I can have it use a blueprint's code?

[brazen merlin]

yes

the video will show you all

[supple bane]

alright

gn for real this time 😅

[brazen merlin]

put it on loop when you go to sleep and when you wake up you'll be speaking french in no time

omele du frumage!

@timber knoll them old peeps know what im talkin bout

[timber knoll]

I'm too young in that case 😂

[brazen merlin]

well, its a reference to Dexters Lab, an cartoon where Dexter listens to a french cd to learn the french language. but it bugs out and the same phrase repeats over and over again

that's all he can see the next day, and as awkward as it is, it works out where that is the thing to say in every situation

[timber knoll]

pffff that's been too long ago for me XD

[brazen merlin]

yeh..

[gentle urchin]

i knew it sounded familiar!

[storm vigil]

is there a way to automatically unreference assets within a folder so that I can delete the folder without crashing? Thank you

[spark cliff]

not that i've found, reference viewer helps

[harsh juniper]

Hi, I have a scene root that is parent to 10.000 instances of instanced static mesh. It renders fast. However, when I move the scene root, performance goes away.
How can I effectively move all instanced meshes at once, without losing performance?

[gentle urchin]

c++

[harsh juniper]

I can do it in c++, however my blueprint code calls one node update in one actor, once per frame.

[gentle urchin]

sounds something like what im doing,

altho at 1/10th of the amount

there are some tricks in c++ that arent exposed to bp tho, will get you further

beyond the regular perf diff

[harsh juniper]

Ok, so how would I do it in cpp?

[bleak hornet]

trying to make 2conditions, "DIE ON HIT" and "DIE ON EXPLODE"

any help?

[gentle urchin]

well most of it would be like in bp, with the exception of this i think (haven't tested myself (yet))

[harsh juniper]

will look into it, thank you 🙂

[timber knoll]

cant read that

[rough cedar]

I have a animation montage I want to play while my character is sliding on the ground. But when I fire the montage it looks like the animation is half way between my walking animation and the slide. almost like a 50% blend of the 2. any ideas what it could be?

this is in my characters bp

This is in my anim bp

[fiery glen]

How is the montage blended?

[vestal plinth]

I have a character blueprint that's set as the default pawn, set to receive input, etc. It's not receiving ANY input though. what have I forgotten?

[rough cedar]

I'm using this

maybe something in here?

[odd ember]

That's cool, what did you use?

[odd ember]

have you tried asking in #animation ?

[keen wedge]

Hi all, quick question if I may...

I have a small game where enemies are spawned and give off "threat"... the object is to collect the enemies and destroy them, reducing the threat to zero - game over you win etc...

At the moment, the gameover condition is being checked against the remaining threat. Because these values are floats, when they are getting added together there is a tiny little fraction left over, so, although I remove the cumulative threat for each enemy, its never actually gets to zero (unless you destroy the very first enemy quickly and no more spawn).

I looked at the IsNearly node, and noted it has a Tolerance property. I set this to 0.1 for good measure, being that the values I am left with are things like 0.000763 etc, it still didn't seem to work. The existing logic was just check for <= 0 etc.

I wondered if perhaps there was something else I could do? I was hoping to avoid wiring up specific values if possible, e.g. <= 1, but the floats are a bit of a pain in the arse. Only other thought it is to move to a solution which counts the number of enemies instead and then checks whether that is zero, as that would be integer based instead.

[odd ember]

I'd check if you have a bug first

nearly equal is pretty good at picking up on things

but you could also try rounding

[maiden wadi]

0.000763 would definitely return true for nearly equal zero at 0.1 tolerance. If you have a set amount of enemies each map, it could be worth turning the threat display into nothing more than a visual, and just rely on the actual enemy count for game ending logic. If you're using a spawning system that spawns until a set amount of threat is reached, it could be worth just doing a simple check based on the lowest threat enemy versus how much threat level you have left for spawning.

[keen wedge]

Stepped through it a few times, and it was always the same, if only one enemy was spawned and destroyed, all all worked fine. When there were two or more, the issue with the floats became apparent, and after destroying the last enemy there was still a little bit of "threat" left in the game preventing the win.

I changed the value on NearlyZero to 0.001 and that seems to have resolved it for now. Feels a bit of an arbitary value though, so think I'll probably re-engineer the mechanic to use the number of enemies instead. Not sure why the 0.1 value didn't work yesterday, maybe I wired it up wrong when tired. 🙂

[keen wedge]

Yeah, I think that's the way I'll go when I iterate over this feature again. The enemies keep spawning, but there is enough time in between for the player to destroy all that are in the level, if they are quick, and thus end the game. So maintaining the count of spawned enemies and checking for when that's zero is probably going to be safer. I prefer the constant of zero than having to choose a tolerance value which may/may not be ok for all occasions etc. 🙂

[winged sentinel]

why is my print string outputing my characters bp instead of what im actually trying to get

i have it connected to get current active montage and it keep outputting my base character bp

doesnt make any sense to me

[haughty nymph]

i get this warning "Blueprint Runtime Error: "Accessed None trying to read property CallFunc_Create_ReturnValue". Blueprint: Menu Function: Execute Ubergraph Menu Graph: EventGraph Node: Add to Viewport
"

[heavy lion]

Is it possible to blend post process settings in a blueprint?
For example, blend bloom intensity from one value to another over time?

[winged sentinel]

yes

wait sorry

wym by blend

ik you can control post process from bp

[heavy lion]

I cant seem to find any options to do so

Ahh, Set members in PostProcessSettings

[odd ember]

yeah structs in BP use the details panel

[dapper bobcat]

It's likely to be something in the construction script or construct event on your widget

[eternal drum]

How would i put binds/bounds on a camera or object so it for example doesn't go under -90 on the pitch axis?

[pallid gate]

is it a lot of work to get a menu that can scale the skeleton ect ?

[odd ember]

just set the pitch axis to what you want once and never allow it to be modified

[odd ember]

you'll have to elaborate

[odd ember]

but if you want more than this you can clamp values

[pallid gate]

basically a character creation menu

[odd ember]

if you have to ask this question I'd say pretty damn hard

[haughty nymph]

where can i add my return value from the create widget node to

[sharp rapids]

Get the angle between camera forward and target direction, then use it to get normalized direction in screen space. Then clamp the direction vector to the edges

[odd ember]

also if you're new and you're building something that requires a character creation screen, I'd recommend scoping down your project

[tight schooner]

If it's a visual effect you can also look into doing it as Niagara mesh particle system

[odd ember]

hmm interesting, so dot acos? how do you handle dot being left right agnostic?

[pallid gate]

yeah im a little ahead of my self rn lol but its one of my main things to learn / get a grasp on

[odd ember]

why don't you start by making some fun gameplay happen instead of trying to focus on technicalities? you can build a small game around fun gameplay. you can't build a game with no gameplay and only a character creator

[heavy lion]

Is it at all possible to have an asset which is an array of curves? Instead of having a curve for every single value?

So I could do away with this and have them all exist within a single asset?

[odd ember]

something like a curve table perhaps?

curve atlas?

[sharp rapids]

Actually I used this to get the angle
It returns -180 to 180
Then,
x = r.cos(theta)
y = r.sin(theta)
(x,y) is the normalized vector in screen space

[tight schooner]

A data asset but it's an array of references to these curves...

Wouldn't be strictly 1 asset though

[odd ember]

hmm isn't atan2 supposed to be used with like atan2(y, x)?

[sharp rapids]

idk, But I did have to exchange x and y while setting the position of the widget

[odd ember]

but I'll take a look regardless, if this works even to some degree it'll save me doing the full complex viewmatrix bs

[odd ember]

very well, I'll give it a go

thanks a bunch

[unique falcon]

Hello i'm new to UE4 i was wondering why is there UMG and the hud blueprint to render a UI on the screen?which one should i use?

i've read some stuff about both of it and i think im going to use UMG for the main menu UI and for rendeing some stuff like the crosshair or the health bar i should use the hud blueprint

am i on the right way?

[odd ember]

how did you handle the clamping?

I can't seem to replicate your results

[sharp rapids]

In Screen Space, Y is up-down and X is left-right
Check the absolute values of X and Y,
if Y is bigger, set the widget position to the upper/lower edge of the screen (lower or upper edge is calculated based on sign of Y), update the X position
if X is bigger, set the widget position to the left/right edge of the screen (again calculate using sign of X), and update the Y position

It's not really 'clamping' the values per se

[odd ember]

ah I see

I've gotten a normal in screenspace so far and I thought I could multiply that with viewport size

but I guess it isn't that easy

I'm trying to avoid having a separate widget space

[sharp rapids]

Yeah, That seems to give some weird results for me

[odd ember]

well I had to normalize the normals to an alpha value

so both x and y have a range from 0..1

[sharp rapids]

The widget actually performed an ellipse on the screen instead of sticking to the edges 🤷‍♂️

[odd ember]

I think that's fine technically. it's essentially trying to follow a circle bigger than the viewport

but clamps to viewport edge

as I understand it

[sharp rapids]

-1 to 1 ?

[odd ember]

ordinarily a normal would have -1..1

[sharp rapids]

0 to 1 would only give you the upper right corner of the viewport always

[odd ember]

but if you create a constant bias you can normalize it to alpha scale

so 0..1

not if you multiply by the viewport extents

it becomes percentage of the viewport

but I'm not sure if it works for this method

[sharp rapids]

I'm not sure how to handle the clamping in that case

[odd ember]

yeah that's a good point. if the circle would be big enough the clamping would be automatic

atm I'm trying to just make it work without clamping and I'm getting very odd results

[odd ember]

using just this

[sharp rapids]

That gives a circle

Multiplying the values by a large number and clamping them gave some odd results.

[odd ember]

but I assume you multiply by viewport center then?

[sharp rapids]

what? didn't understant

I simply have an Image anchored to the center of the screen

[odd ember]

ah that's why

[sharp rapids]

So, (0,0) is already the center

[odd ember]

yep ok

so I spawn a widget on screen

[sharp rapids]

Yeah

Keep in mind, I'm changing the position of an Image withing the Widget, not the whole widget

[odd ember]

but yeah I still can't get it to work properly even with center viewport multiplication

I'm certain the math is correct but I just have no clue what to do with it

[sharp rapids]

You have the normal vector, right?

[odd ember]

yeah, cos(angle), sin(angle)

[sharp rapids]

does the widget perform a circle then?

If you set this vector as the position

[odd ember]

if I just set the vector it stays in upper left corner/disappears

[sharp rapids]

Weird 🤔

[odd ember]

actually

[sharp rapids]

It's a normal vector

[odd ember]

I see it now

[odd ember]

yeah but if put it directly as position the position is between -1..1 on both x and y

so it makes sense it stays in the corner

there's some pivot weirdness now I'm sure

it seems to go in a circle that center on the (0, 0) of the viewport

so the upper left corner

when I multiply it with the viewport center

so I'm only getting a quarter of the rotation

[sharp rapids]

Are you multiplying it by the viewport dimensions?

[odd ember]

GetViewportSize() * 0.5

[worthy carbon]

Hi i want to learn how the weapon (pick up, fire weapon, pickup multiple weapons, etc) system works. Does someone knows a good tutorial

[odd ember]

if I don't multiply it by anything viewport it's just stuck in the corner

I need to make the pivot come down from the upper left corner into the center

[sharp rapids]

If you don't multiply it by anything, it should stay in the centre of the screen

[odd ember]

well no

[sharp rapids]

Tracing a circle of very small radius

[odd ember]

it stays in the upper left corner

because it uses normal values

so both x and y are -1..1

[sharp rapids]

These normal values are not relative to Viewport

I'm talking about Cartesian Plane

(0,0) at center

[odd ember]

right but because I don't spawn my widget inside another widget space, I use viewport space

[sharp rapids]

(0,1) to the upper side
(1.0) to right
(-1,0) to left, etc.

[odd ember]

hmm

so were would I convert this

[sharp rapids]

Well, that requires some more math which I'm not aware of then

[odd ember]

currently it seems that the normal uses viewport space, so 0,0 is upper left corner

I tried multiply the normal by ViewportSize() * 0.5 which just makes the radius of the circle tangent the screen center

it does not move the pivot

[sharp rapids]

The normal would use any space we want them to

[sharp rapids]

Try adding ViewportSize/2 to the position?

[odd ember]

adding

of course

that could be it

yep

that centers it

also found alignment

which may be the cartesian you're talking about

it isn't, lol

welp

but ok

[sharp rapids]

The alignment is probably the pivot

[odd ember]

ok I got half a circle showing up by doing ((cos(angle), sin(angle)) * radius) + (ViewportSize() * 0.5)

going out from middle

[odd ember]

possibly

okay

added 90 degrees to the amount of degrees, made the radius larger than the viewport size and it's working

it's missing some accuracy but it's way better than what I had before, so appreciate the help

for the record these are identical, but the one on the lower side is cheaper

[sharp rapids]

Yeah, it's not that accurate

[odd ember]

I think I can play around with the radius of the circle

to make it slightly more accurate

[spiral sand]

Got a weird one. Projected is C++ base and replicated. This problem relates to a prototype (mostly in blueprint) and is not replicated. RTS style game

What should happen:

1. Player selects building what they want to build
2. Shadow/Ghost version of building follows mouse

What is happening:

1. Player selects what building they want to build.
2. Shadow/Ghost Building spawns but doesn't follow mouse
3. If pawn is unpossessed or the PIE is exited but not closed (by clicking on world tree)
4. the pawn is repossessed or the PIE is resumed (by clicking back in the window) the building follows the mouse

Sad part is, I've done this before without this issue

[odd ember]

since this seems to be based in replication issues, have you tried #multiplayer ?

[spiral sand]

As I said, this is not replicated.

This occurs locally only

[worthy frost]

seems like a capture issue

what is Shadow/Ghost building?

[spiral sand]

actor

[worthy frost]

and how do you move the actor?

[sharp rapids]

@odd ember so, you want a circle or a square

[spiral sand]

it's what is mostly BP. All the variables it uses are C++ based right now (the methods will be too when the prototype is done). It is being spawned by a actor component (100% bp currently) that is attached to the player controller. The second it spawns the building it through casting (interface will replace this soon enough) calls a method (event) in the building BP that sets actor to location. Location is passed through the component. The location is based on the mouse location with some offsets.

(code base I am using works, it is from my tutorial series, but I am making an new version of it in C++)

[odd ember]

I think I figured it out, this is basically what I am doing now:

[spiral sand]

@worthy frost here are the methods (events) I am using

also I need to move is previewing I know

[sharp rapids]

@odd ember but that would result in the widget going out of the screen

[odd ember]

it would but you clamp it to ViewportSize() * 0.9

it works for all angles

top down too

[sharp rapids]

For some reason that results in the widget getting stuck in a corner for me

[worthy frost]

and what does MovePreview do @spiral sand

[odd ember]

well you have sub widget space right?

[sharp rapids]

Yeah

[odd ember]

that might be why

[spiral sand]

@worthy frost this is the BP prototype of the BuildingMasterBase class file.

[worthy frost]

sorry i was meant to ask where you get the mouse info from

[odd ember]

I will have more than one of these widgets on screen at the same time, so that's why I think it's better to spawn them directly in viewport

[spiral sand]

the player controller

[worthy frost]

it feels like a focus problem

[spiral sand]

the information is valid and is being correctly passed along.

I was just given a suggestion though that it may be the way the building master is constructed

[worthy frost]

as when you loose focus on the game viewport then regain focus

it fixes itself right?

[spiral sand]

yes

[worthy frost]

tried setting the InputMode to Game?

PlayerController - SetInputMode Game

[spiral sand]

already done. Game Mode and UI mode (due to the nature of the game)

[worthy frost]

interesting, i mean we only ran into that issue when the input mode was wrong in Red Solstice 2

[spiral sand]

I thought it was a focus problem too. Let me quickly tackle the building master base issue (I constructed the base code differently), because that in theory could explain it too.

(if begin play does not finish firing by the time it is suppose to track the mouse the mesh may not being set and by leaving the viewport it sets partially - would also explain a secondary issue)

[sharp rapids]

@odd ember ah, I see

[spiral sand]

Tested both ideas.
Setting the mesh in the construct script did nothing.
re-setting (in case the C++ player controller setting was ignored) the focus for game/UI did not work either

[worthy frost]

do you spawn some widget?

[spiral sand]

I do

There is a widget the player has to click to build the building

[worthy frost]

tried not spawning the widget?

or hiding the widget

see if that fixes it

[spiral sand]

can't spawn the building... will make a dummy key for it

[worthy frost]

your widget could have stole the focus

we have had that happen also

[spiral sand]

hmm

shit

can't really not spawn the widget, nto without a lot of code change

I could just not add it to view port

[worthy frost]

@maiden wadi how do you stop the widget from stealing focus?

[maiden wadi]

First thing I did when starting my most recent project, was make a new Userwidget that is a button, has styling options, but most importantly, it and it's internal UButton has IsFocusable disabled by default.

[worthy frost]

jnot a UMG guy.

[maiden wadi]

UButton has IsFocuable true by default. And it's incredibly annoying.

[spiral sand]

One moment. I seem to have lost something... like the construct script

weird part is it is still firing but it is not even listed as an overrideable now

[maiden wadi]

@spiral sandOn a side note. I haven't been following the conversation long. What button is the widget stealing focus for?

[spiral sand]

it's not the widget

just did without the widget on the view port, using a hot key to spawn the building in.

[maiden wadi]

And that doesn't work either?

[spiral sand]

nope same error. Small update to the problem though

I made one small mistake and this mistake is why it appears to be a focus issue.

[odd ember]

@maiden wadi if you're interested in the offscreen problem from yesterday we got it resolved

[spiral sand]

It is not clicking out of the view port that matters. It is clicking out of the view port and selecting the actor in the world outliner that fixes the problem

[odd ember]

(for all angles)

[maiden wadi]

Always up for learning. 😄

[odd ember]

this is the easiest way to show off what's happening. the radius is the outer bound for where the indicator wants to be, and that is clamped by viewport size. the math itself is getting the angle between the vector of the OtherActor pointing at the camera (or pawn), then translating that into a 2d normal by going normal = (cos(angle), sin(angle)), then (normal * CircleRadius) + GetViewportSize() * 0.5

circle radius can be adjusted based on normal value to get best results

so it's not just a circle but an ellipse effectively

in my case I'm using something like CircleRadius = normal.x > normal.y ? GetViewportSize().x : GetViewportSize().y

[maiden wadi]

Huh. Might have to mess around with that. I was always wondering how to project it to the edge of screen effectively. That'd be a pretty easy way to handle that. Also probably computationally faster than what I have at the moment. 😄

[spiral sand]

yeah definitely not a focus issue I think.

[odd ember]

also avoids math/perf heavy solutions like deprojecting view frustum to get vector intersection

which was the road I was heading down 😅

[sharp rapids]

That sounds ....... complex 😅

[odd ember]

yeah. I mean it is available in BP as well, but requires a very roundabout way of doing things

like you have the find the actual camera to get its FMinimalView struct (because for some reason this isn't available through the camera manager)

[sharp rapids]

btw, you can use the same angle to rotate your widget so it points at the target

the angle you calculated earlier

[odd ember]

ah yeah, appreciate it

I will probably rotate a part of it to give an indicator. have to create a new widget now that the logic is in place

I'm also trying to scale the widget based on distance

but perhaps opacity is a better marker

[maiden wadi]

I'm cheaty. I just get look at rotation from Screen center to screen location with zero Z and use the yaw value of that to set the angle of a right facing arrow.

[sharp rapids]

But lookatrotation only seems to take the position into account 🤔

If character is standing at a location and you get the rotation to the target,
Then you rotate the character in the same place, and again get the rotation,

In both cases, it returns the same value

[maiden wadi]

For the arrow direction. In screenspace.

[sharp rapids]

Aah, Ok

Got it

[maiden wadi]

I do the same thing for quick radial menus. Getting the angle of Initial mouse location to current mouse location after pressing the key allows very easy radial menu selection. Can choose the option from an array based on the angle.

I prefer float comparisons for this. Some people use delays.

[odd ember]

lookat is the direction from the other actor to the player character/camera

[maiden wadi]

In regards to this, how often should the hit be able to damage? Like once per second, or?

[sharp rapids]

I thought it was the direction from start to target (or whatever the other var is called)

[odd ember]

it is, so if we plug in the other actor's location into that, we get the direction from the other actor towards our player character/camera

[sharp rapids]

Why is there a branch with always true condition?
might as well remove it

[odd ember]

if it's being registered every frame, your issue isn't with this blueprint. your issue is how your hit registers every frame

[sharp rapids]

Huh
I thought it was the other way

[odd ember]

start is where we start looking from

target is where we look towards

[sharp rapids]

Exactly

So, If Start is the player character and target is the target actor

It should give the direction from Player to Target, right?

[odd ember]

then we are looking from the player character

but that's not what we want

we want where the other actor is looking at the player from

yes

[sharp rapids]

I did all that the other way though

We find where the target is from the player's perspective

[odd ember]

you already have where your character is looking from, that's the forward vector 😉

[maiden wadi]

@sudden briar Try this out.

[sharp rapids]

The forward vector is where the character is looking at
If the target is to the right of the character then that gives us 90 degrees between the forward vector and the direction vector to the target

90 degrees means the indicator should be displayed along the right edge of the viewport

This is what we've been talking about, right?

[odd ember]

I would personally look into structuring your architecture so this doesn't happen. because if it happened here, it will happen again elsewhere

[odd ember]

that's potentially true, and I did add 90 degrees to make it work out right

so it may be a question of using right vector instead of forward vector

[maiden wadi]

Hmm.. I wonder if that's a possible feature request. It would be nice to be able to set macro's local variable defaults.

[sharp rapids]

you can just set it at the beginning of the function before doing anything

[maiden wadi]

There are cases where that isn't applicable. Since that would force you to execute that macro at least once before use. That isn't ideal in UI uses at least.

[odd ember]

as far as I understand macros aren't actually like functions

they are just collapsed graph

[maiden wadi]

I use them to keep variable lists clean. I love macro's local variables.

[sharp rapids]

Yes, but if you're accessing the local variable, that means you're executing the macro anyway?
Or am I forgetting something?

[maiden wadi]

Macros are generally meant to be ran multiple times and keep state. Otherwise there's no point in using them and you should just use a function. To set up initial state in a macro would require having a bool and switching on whether it's been executed before.

One wouldn't think it would be that difficult for some UE graph wizard to add an editable value in the details panel for the node.

[odd ember]

afaik there is nothing keeping macros stateful

I avoid them like the plague

[icy dragon]

this tbh

[maiden wadi]

I've never had problems with them. 🤷‍♂️

[odd ember]

I've never had use for latent macros in any capacity

https://www.reddit.com/r/unrealengine/comments/6r5np4/blueprints_trying_to_sort_actor_array_by_distance/

search at google "ue4 sort array by distance", if it is C++, then create your own function in C++ and expose that function to blueprints

There is a blueprint function called "Max/min array element", which return element with it's index, just do with your array and remove that index element after adding to new array. Unreal engine should have that kind of functions in blueprints as well for sorting arrays.

[odd ember]

the best answer is have these in a priority queue

or at least that's how I would do it

of course one of the very valid data structures that still isn't natively implemented in UE4 😔

[formal wren]

Is it possible to initialize an asset reference using it's path in the content folder?

E.g. I want to get an array of Texture2D references by iterating over all .uasset files in my textures folder

[formal wren]

Is the AssetData Struct bugged? Why can't I set its member?

[brazen merlin]

Unless there is a better way, i store all applicable textured2d assets in a name|texture2d map. Then I fetch any textures by name. Maps must have unique names (keys) so you can have an array of all appropriate names and search that way

[formal wren]

Yeah, that's a way. But I would have to maintain that map. Textures in my game are modable. User jpegs are loaded from the mod folder at runtime. But I also want to load everything which is in the vanilla textures folder as well using the same function 🙂

[brazen merlin]

I think soft objects would be the area but ive not worked with them really

[formal wren]

This looks promising: https://isaratech.com/ue4-get-assets-by-path-in-blueprints-with-the-assetregistry/

[odd ember]

maybe it's not exposed to be writeable for blueprint. generally I would avoid heavy struct editing in BP

it's a can of worms due to how cpp handles copies

[sand shore]

because you're not really meant to mutate asset data in this way. Modifying these won't change the actual asset, or it's metadata. You should be requesting another asset data if you just want valid data that references another package.

it isn't bugged, that's an intentional design choice

[formal wren]

Makes sense! Thx 🙂

[steel zealot]

Hey guys. Is there any way to disable a first person characters hud from appearing during the loading screen? Currently I have an empty level which is used to display the main menu, and at the end of the script I have a DestroyActor function to prevent the HUD from appearing. I'm sure theres a better way but I'm not sure.

[maiden wadi]

Why does destroying your character have anything to do with your HUD?

[steel zealot]

The character has a hud built in but for some reason when the main menu is displayed, the hud is being called and drawn over the main menu

so the only way ive found thus far to prevent that is to destroy the character

[maiden wadi]

By hud I'm assuming you mean a widget. This is one reason that character spawning should not handle widget creation. At the absolute most, your character should call to the local controller's actuall AHUD class, and tell AHUD that it's spawned. And AHUD can manage your actual widget UI. Then you can not use that HUD class in the main menu.

[spiral sand]

@worthy frost in doing some reading it appears this issue happens to others too when the root is the collision mesh, which still makes no sense but hey at least I'm not the only one with this issue

[dry glen]

I'm trying to set up a metahuman with the Advanced Locomotion System following a tutorial but when i start playing the animations i get some weird clipping between the jacket and head

[trim matrix]

Hi, i 'm needed to set vlue of this variable "Wood Life" that is stored in another BP it ask me the target what should i put in it?

[dry glen]

an im not really sure whats causing this because the custuction script seems fine

[steel zealot]

Appreciate the response. Actually managed to fix it by setting up a second game mode, which i should have done originally.

[trim matrix]

Also i want to hide this object when this variable reach zero, how should i connect the trigger?

this happen when game start ofc

[velvet smelt]

Connect a branch

[odd ember]

just connect what you have to new visibility

no branch needed here

[trim matrix]

but if i connect only to new visibility the exec node is not called

i need eoither to use event tick or something else?

[velvet smelt]

If the variable “WoodLife” is in another BP, then you have to get a reference to that BP. Cast and store the reference as a var. Then drag off from the reference/var and search for “WoodLife”

[velvet smelt]

Is it like that on all LOD levels?

[dry glen]

as of now i havent added all the LOD levels so its at 0 right now

[icy dragon]

MetaHumans already have 8 LODs by default.

[velvet smelt]

Something you can do…since he’s wearing a hoodie, you can hide his torso with a material that’s blank

[dry glen]

Ok so i added a LODsync and plugged in the LODs and it works fine on lod 0 but not at default -1

Oh i figured it out

[velvet smelt]

Hoodie missing?

[dry glen]

I had a misspelled word somewhere

thanks for the help though, i think it was a problem with the LODs

looks like you might need to compile it yourself?

hard to tell

follow the instructions

we know as much as you about the plugin

yes I need to compile it myself

Im probably just gonna make movement myself

i need the experience anyway

What are you trying to do

[shadow crescent]

I am following a guide for a 3rd person game

I want to keep my 1st person perspective

[odd ember]

so you started with first person instead of third person because...?

[faint pasture]

That's fine, what are you actually trying to do here?

what is this bit of code supposed to do

[odd ember]

you should add a camera to your first person character I guess

[shadow crescent]

omg, doesn't starter content come with one, lol

[odd ember]

the default engine comes free with one

you just need to add one

[shadow crescent]

it has one already

and apparently 2 guns, lol

[odd ember]

right but you need another

[odd ember]

don't talk to me or my gun again

no but for serious

[shadow crescent]

lol

[odd ember]

you need a third person camera

[shadow crescent]

k

[faint pasture]

One is what you see, the other is what other ppl see. Are you trying to have 3rd or 1st person view?

[shadow crescent]

1st person view

like in Satisfactory

[odd ember]

well right now you have first person

[shadow crescent]

I wanna place things into the world and need this reference for line tracing

[faint pasture]

K then you're fine, what are you trying to do with that code snippet you posted?

[shadow crescent]

omg, thanks for helping me to see the light, lol

but wouldn't I wanna stick with the same view as the player has, to ensure accuracy?

[random plaza]

what's the best way to save and load physics objects that ive already spawned into the world? idk how to upload my project files so people can help, could i just give you the uasset file?

[faint pasture]

For line tracing you already have everything you need. Just trace out from the camera you already have

[odd ember]

wait so you don't want a third person camera?

[odd ember]

probably better to ask in #legacy-physics

[faint pasture]

No he doesn't, I just don't know WTF that bit of code he posted was trying to do lmao.

[shadow crescent]

following this dude, about 4 mins in
https://www.youtube.com/watch?v=Z8u1EUJxfOI&list=PLGm9gBuuMTeuLQythBu61WK7qO31RRH7l&index=4

[faint pasture]

What is THIS trying to do?

OK i gotcha. He's makign a component to handle the building mechanic and move the ghost item around

[shadow crescent]

yup

love the idea 😛

[umbral ginkgo]

I have a custom event to spawn an actor and I want that event to trigger on collision with a box trigger. What's the best way to do that?

[faint pasture]

This is where you fucked up.

[shadow crescent]

yup

[odd ember]

you're in luck. box collisions have an event called OnComponentBeginOverlap

use that

[faint pasture]

Do it just like he is. Just telling the Build Component that its Camera variable should be the camera on the character. This is done from the Character

[hard charm]

yes

[faint pasture]

He is setting BuildComponent's Camera to be Characters Camera

[hard charm]

someone knows how it would be

[shadow crescent]

I don't understand enough yet on how to change it to 1st so will follow him and figure it out later

[umbral ginkgo]

thx bro

[shadow crescent]

thanks for your insight @faint pasture

will be easier next time around 🙂

[faint pasture]

First try doing exactly what I posted. In the Character, which should contain the BuildComponent, set BuildComponents Camera to be the Character's Camera on Characters Begin Play.

[shadow crescent]

will do

[shadow crescent]

sorry for noob question but would you recommend that on the begin play event?

[umbral ginkgo]

yes

[shadow crescent]

ta

I really need some super beginner training, lol

this is not working, lol

[faint pasture]

That isn't the same thing

[shadow crescent]

I suspected not

[faint pasture]

Drag off build component, set it's camera

[odd ember]

if you check there's a bunch of links pinned that you can check out

[shadow crescent]

nothing listed though, lol

'tis the first thing I tried

[odd ember]

in the channel

this discord channel

pinned

[shadow crescent]

ta, will take a look

[faint pasture]

Does build component have a camera variable yet?

[shadow crescent]

nope

when I drag from the component and type cam nothing shows

[leaden breach]

aight so I made some VR arms and they are acting up a bit

[stable osprey]

hi,,,, i'm having issues with playing my game,,,, for some reason when I click play it only simulates the blueprint i'm in,,, i dunno why

[faint pasture]

You skipped the part where you give build component a camera variable then.

Or you named it something different.

[shadow crescent]

this is what I have now (but still in 3rd person) ... will clarify how to switch the came later as I have been getting "stuck in the details"

oops

[tight schooner]

A plane isn't a primitive collision shape so maybe you need to use Complex Collision or make a really thin box collider, lol.

[quick lance]

I ended up using a thin box.

[tight schooner]

Yeah complex can be wonky in some scenarios

[umbral ginkgo]

ok, what is the simplest way to spawn in an actor from collision with a box trigger?

k thx

[supple bane]

I got the movement working

well I made my own

its not spot on but its close enough

[trim matrix]

https://cdn.discordapp.com/attachments/857835276843352094/914412240478810192/unknown.png

does anyone know how to make this work

[tawdry surge]

Change the type input you are passing

[hybrid ether]

I'm using this in game mode after Died. It works in my multiplayer game but problem is that it resets player but not "controller" example: UI shows 0% health

Is there way to reset whole player after getting killed in multiplayer game?

Like open level to current again but without loss multiplayer session

[odd ember]

there is a way but it's cpp only

seamless travel

[icy dragon]

Thank me later

[trim matrix]

i worked it out

but thanks

❤️

Hey guys, I'm working on a jump system for a small project, Im trying to emulate something like in the FF13 games where the jump is fixed to a position. could someone point me to the right direction for resources, I think I need to look at, Camera and Animation material, is there anything else I would need to look into? Just looking for an idea on the right keywords to search for, thanks all!

[icy dragon]

I think it's just as simple as playing the jump animation and lerping position from one point to another.

[odd ember]

I'm not sure what jump fixed to a position means? a fixed position in front? back? where the character stands?

[icy dragon]

It's more of the jump positions are predetermined.

[trim matrix]

https://youtu.be/wzFGvmJ6alg?t=857

like this

[icy dragon]

At least in first Final Fantasy 13, you can't jump around at your own will (as there's no need to - the game is very linear and not a platformer), so the characters would jump from one point to another only in specific points in the map.

[trim matrix]

^^ this yeah

[icy dragon]

(also can't forget how the "prologue" chapters drags out for hours but I digress)

[trim matrix]

yeah that was terrible

[odd ember]

looks like something you could set up with sequencer generally

[icy dragon]

Or simple lerp w/ timeline

[odd ember]

lerp would linearly bring you to the end position

[icy dragon]

And that's pretty much how it goes in the game. It's just basically play (exaggerated) jump animation and move the player entity into position.

[odd ember]

yeah but a jump is a curve in space

it's not linear

it goes start > jump apex > end

[icy dragon]

I'm thinking about the jump animation do the lift up.

Not necessarily "in-place" animation.

[odd ember]

that's bound to cause issues

I'd handle it as a cinematic and have the character teleport basically

hence sequencer

it also simplifies the fact that you have cinematic "jumps" separate from game logic

[trim matrix]

Cool I look into both options then, cheers

[warm rain]

I'm new to unreal and I'm trying to figure out a way to get all objects with a certain tag and then run some code on each of them. The problem I'm having is that all the objects are different classes and have run different code so I can't reference one function.

[fiery swallow]

sounds like something an interface is for?

[odd ember]

it's exactly what an interface is for

though it depends on what function parameters each class has

there has to be some parity in the function signature

[icy dragon]

Though he mentions tag, so I'm assuming it has to do with GameplayTags

I'm not versed in GameplayTags yet

[warm rain]

It turns out the tag part was unnecessary, I can now just use does implement interface.

[hard charm]

Guys I have already created my own graphing script for statistics 🙂

[tawdry surge]

There's also a get all actors with tag, but both those functions are pretty heavy because they get everything and then check if it has whatever you're looking for..
If you can avoid it, I'd try get direct references another way or do an event dispatcher and have each of your actors implement a delegate event to run the code you want

[hard charm]

too easy

[icy dragon]

No copying from Kantan Charts? 😏

[tawdry surge]

Well now make it fancy..
With like colors and dots or something

[hard charm]

this is mine I did it from 0

[hard charm]

yes that's the next step

I'm putting more data to show me but it works very well

[icy dragon]

You know, because kantan charts is free and open source, just in case you claiming it as yours, made from scratch. But I'm overthinking tbh

[hard charm]

I think it is not worth buying some of this if you can do it yourself

[icy dragon]

Buying for $0?

[tawdry surge]

If it's easy to do and you wanna do it, I always find it's easier to work with my code then someone else's

[icy dragon]

I'd prefer making things from scratch because cooler first, practical second.

Imagine the street cred gained from going deep into the code, heck yeah.

Not to mention potential to naming things yourself to be said in public presentations

[tawdry surge]

Haha idk if you've watched the cppcon presentations, but they get deep..
I gotta pop an asprine in advance

[pine idol]

How do you create a bullet tracer round that can be seen, regardless of distance from the actor? Similar to how you can see Bullets flying across the map, and from the barrel of your gun in any modern fps game, like battlefield, cod, etc.

The material will always fade drastically or disappear completely when it reaches an unknown distance, and I've never been able to figure out how to fix that.

[brazen merlin]

sounds a bit more like a vfx questions, but if you use niagra ribbons and a line trace, you can draw a line. with a little finessing you can make it as if the bullet took a few frames to reach that distance or else it will be an instance line. the fade effect and appearance can all be handled in the ribbin

[pine idol]

apologies, I was looking for a material channel but didn't see one. I'll ask there. 🙂

[stray mural]

If I have some blueprint uassets files, is there any way to 'view' them without adding them to some functional UE project? 3rd party or otherwise tool? Just a semi functional viewer? Original uproject is un-openable, so can't do export from it, and just want to examine some things

[icy dragon]

No.

There is https://blueprintue.com, but it's more for copy pasting BP nodes.

[stray mural]

yeah, need access to BP nodes first 😦 I did find a uasset 3d model viewer, but nothing for blueprints

[brazen merlin]

could you take the uassets of your bps and open them in a new project?

[spark steppe]

first of all make a full backup of the broken project

then take out assets and put them back in until you found the "corrupted" one

then get that asset from source control or the backups you make regular (right?!), otherwise check if there's an autosave of it which still works

[thorn ermine]

Also check your log file, it may tell you what the problem is.

[stray mural]

oh there is like a million problems, its not my original project that 'went bad', it was just never good/functional, requires things I don't have (plugins, and whatnot)
and aside from spending several days trying to unwind things, I just wanted to read/reference for educational purposes by looking at some of the uassets.
(e.g. downloaded a old sample educational project off internet, and even though using right version, just busted af)

[surreal peak]

I mean, theoretically you can move the files, if all references are moved, from one project to another, given they are the same engine version

But there are of course lots of terms and conditions attached

It's probably better to at least get that project to open and use the Migrate function to get the files out.

[icy dragon]

Shall the project unable to open at all and File Explorer is the last resort, at least make sure to keep the file structure all the same when copying from one Content folder to another, as to not break the references.

[tidal marlin]

Noob question. Why Add movement input with floationg pawn movement not working when i spawn actor?

[faint pasture]

Million reasons. Is the Actor a Pawn that you're Possessing? How are you adding the movement input?

[rancid steppe]

my NPC Essential enemy move to me but without anim walking

how can i fix it

[wicked shoal]

Im trying to adjust friction based on vehicle speed. is there a way to adjust paramaters to the wheeldata asset on runtime?

[velvet dagger]

Just curious, how hard would it be to make a game from start to finish entirely in blueprint? I remember hearing something about how there's certain things that text coding is capable of doing that blueprint can't do, or is really difficult with blueprint to do

[earnest tangle]

Depends on type of game and features you want

[warm rain]

for some reason specifically my e input isnt working when i am holding control. I changed it to f and it worked perfectly.

[icy dragon]

Yes, depends on the game and features. Some is doable entirely in BP, some would involve C++ into the mix.

(I don't say purely C++, because some things are legitimately PITA to do in Unreal C++ as opposed to side loading the job to BP)

[velvet dagger]

Thank you so much :)

What does PITA mean though?

[icy dragon]

Pain in the a||rse||

[warm rain]

I tried like 5 other keys and every one works with control except for e

[brazen merlin]

been doing that for awhile now

[velvet dagger]

What things have you achieved doing it that way?

[brazen merlin]

the first thing i made was a fps shooter, nothing great, but thats the basis of the engine

[velvet dagger]

Awesome none of the less

[sharp rapids]

Are using e somewhere else?

[tidal marlin]

Like this

If i add him on scene all work correct

But not when i spawn it

[faint pasture]

@tidal marlin what does that print string output? But also why are you not using a ProjectileMovementComponent for your rocket?

[tidal marlin]

Im not sure that if i using projectile movement, i can change speed.

Print string i use to see that all variables is correct

k i fix it

Need change auto posses ai

[unique falcon]

I'm trying to implement a crosshair for a tank by using a line trace but for some reason its not accurate, First i use line trace by channel then store the hit location in a variable and then in the hud i retrieve the value using project BP i display it on screen but for some reason its not accurate i could fix it by adjusting the return values on the project BP but is it really the correct way to do it?

Also for some reason when i shoot the crosshair jumps down why is that?

[faint pasture]

Your rockets should not be pawns lol, and yes you can change velocity in projectile movement component.

[unique falcon]

Here is the video showing the problem

[faint pasture]

@unique falcon That's not how you draw something on screen space from world space. You need to convert the coordinates.

And when you shoot you're probably tracing and hitting your shell.

[unique falcon]

"convert the coordinates" which coordinates ?

[faint pasture]

Convert 3d world to 2d screen

[unique falcon]

you mean i have to convert the return value from project BP?

[faint pasture]

Is that what that project node does? Haven't seen that one.

[unique falcon]

yes

[faint pasture]

You need to offset it. The point you're giving it is the top left corner.

Haven't seen that draw texture node but try setting texture u and v to 0.5

[unique falcon]

i think its probably becausse of the texture width and height

[faint pasture]

Try setting the UVs to 0.5. That might be the UV they map to the XY

[faint pasture]

Lmao

Ok then offset the XY by half the width

Subtract 27 from x and y

[unique falcon]

subtracting does work but is it the correct way to do it

but what about the weird movement of the line trace and the crosshair

when i shoot it just jumps down for no reason

look at the video you'll see what i mean

[faint pasture]

You're probably hitting your projectile with the trace unless you have recoil

Have the projectile collision NOT block whatever channel you're tracing in.

[unique falcon]

oh i think you are right ill try that

its currently set to block all dynamic

[unique falcon]

i have to do that in BP right?

[faint pasture]

Just edit the collision settings. Unblock whatever trace channel you use for aiming.

[unique falcon]

what do you mean by unblocking "trace channel"

you mean these two?

oh wow

thank you so much it's literally been a few days i was dealing with it

i think i have to go read some docs about physics

[faint pasture]

@unique falcon https://docs.unrealengine.com/4.27/en-US/InteractiveExperiences/Physics/Collision/Overview/

[whole dune]

Hi quick question: is there a way to convert a Texture 2D Dynamic to a Texture 2D in blueprints? Im downloading images but want to change its parameter values at runtime so i have to convert it

[bright frigate]

Hello, I have a prompt for when I am overlapping the box and it comes up fine. But it doesn't seem to go away even after leaving the box. Any thoughts? This should've just ... worked?

[faint pasture]

Save the widget to a variable

[bright frigate]

I did that too, didn't make a difference. Changed the order too.

[bright frigate]

This has solved it

So that means that the multiple overlaps are creating multiple widgets and it's always one short of removing the last widget. The question is why? Why not remove all the widgets?

[bright frigate]

wth! All my light blueprints are just messed up on their own! I know the first thing you'll say is I did something, but I haven't touched this blueprint in weeks after making everything perfect. I just checked and all their locations are messed up, they're no longer as they were (e.g. light parent of 2 lights, both children are no longer children and just listed as separate components in the hierarchy instead of being parented and their locations are all offset at random spots)

wth man

I just don't understand these weird things, unbelievable

[strong halo]

Hi! What is the correct way to make a tooltip on specific words like this?

So far I've found only two ways:
1 - break the text into multiple text blocks, which doesn't work with multiline
2 - make a custom rich text decorator in C++, which may or may not be reinventing the wheel

[umbral ginkgo]

Is there any way I can get trigger collision input from other blueprints besides the level blueprint? I want to spawn an object when the player walks into a box trigger except the spawn system is on the player blueprint and cant be moved elsewhere because it relies on a variable in said player blueprint

[sand yacht]

I want to make a procedurally generated office, does anyone have a good tutorial for this?

[strong halo]

@sand yacht multifloor or not?
