fuck this

#

@gloomy linden i have NO FUCKING IDEA how to use the timeline besides lerping it

maiden wadi Jun 7, 2020, 9:24 PM

#

Is this for first person?

paper magnet Jun 7, 2020, 9:25 PM

#

yes

snow halo Jun 7, 2020, 9:27 PM

#

Is it possible to have a branch inside a function which if true would then fire the actual functions exec pin and if false the exec pin would not fire?

#

or does a BP functions exec output pin always fire when the function is executed?

#

i'll keep that in mind, but if i go c++ this is a non-issue for me hehe.. much more flexible

paper magnet Jun 7, 2020, 9:30 PM

#

what node would i pull from here if id want to create a rotation of the X axis by 45 degrees

snow halo Jun 7, 2020, 9:30 PM

#

i'm just wondering about stock blueprints

#

i had forgotten that the output exec of a function always fires

paper magnet Jun 7, 2020, 9:37 PM

#

"plug in 45"

#

what? do i make a variable for this?

old rock Jun 7, 2020, 9:37 PM

#

for some reason I’m coming up empty: can I add a component (e.g. a SphereComponent) at runtime? I’ve searched for “add component”, “spawn component”, “make component”… nothing

paper magnet Jun 7, 2020, 9:40 PM

#

uh

📎 unknown.png

#

this code just swaps my controls

#

goddamn it

#

i made the increment 45

old rock Jun 7, 2020, 9:42 PM

#

@trim matrix that didn’t show up either, but apparently because I was in an actor component’s blueprint. in an actor’s blueprint it works fine. thanks!

paper magnet Jun 7, 2020, 9:42 PM

#

okay i know about that one i dont really need to increment

#

just transition from A to B

#

but for some reason it just swaps my controls

#

oh okay

#

so should the "A" in the lerp be 0?

#

it doesnt rotate my camera and overall makes my character act weird

#

📎 unknown.png

#

hm

#

so uh

#

i see

#

is there a way i can make the camera have the same rotation or just be attached to the actor?

#

or actually why not rotate THE capsule and the camera at the same time

#

i guess you turned away cause im stupid

@void cobalt get its skeletal mesh and set simulating physics to true

void cobalt Jun 7, 2020, 9:51 PM

#

📎 unknown.png

#

like this?

#

it didnt work

#

@thin rapids

thin rapids Jun 7, 2020, 9:52 PM

#

is it a skeletal mesh?

void cobalt Jun 7, 2020, 9:52 PM

#

yes

#

i tried both skeletal and normal mesh

#

neither work

thin rapids Jun 7, 2020, 9:53 PM

#

does it have a physics asset?

void cobalt Jun 7, 2020, 9:53 PM

#

yes

#

its the default ue4 mannequin

static charm Jun 7, 2020, 9:55 PM

#

collision has to be enabled for that mesh, you can enable it before turning on physics

void cobalt Jun 7, 2020, 9:56 PM

#

still doesnt work

#

i just dont know why this doesnt work

📎 unknown.png

#

its so painfully simple that it should work, but it doesnt

#

if hp below 0 = is alive? No

#

if is alive? NO = set simulate physics true

paper magnet Jun 7, 2020, 9:58 PM

i guess why question wont get an answer

shade, just add a camera to the actor, then it would always follow rotation

paper magnet Jun 7, 2020, 10:00 PM

#

i fucking did..

thin rapids Jun 7, 2020, 10:01 PM

#

@paper magnet perhaps you could also try other places to find the information you want if you didn't find it here, like the ue4 forums

#

so no one knows how to make a mesh ragdoll after dying?

static charm Jun 7, 2020, 10:07 PM

dan already said how

#

you need to check if the code if firing after the branch

how do I replace a playable character with blueprints and all to another in another project? I have a multiplayer template and need the humans changed to another ones

void cobalt Jun 7, 2020, 10:07 PM

#

i did

static charm Jun 7, 2020, 10:07 PM

#

or test the skeleal mesh itself by dragging the asset itself into the level and turning on physics for its default.

void cobalt Jun 7, 2020, 10:07 PM

#

and it works

#

but its not ragdolling

#

ok i put a skeletal mesh in and it works

📎 unknown.png

#

but on my enemy ai it doesnt turn into a ragdoll

static charm Jun 7, 2020, 10:10 PM

#

it's possible there's some conflicting code, or it's not the correct skeletal selected.

#

otherwise, no idea

void cobalt Jun 7, 2020, 10:11 PM

#

this is the only other code on that enemy bp

📎 unknown.png

static charm Jun 7, 2020, 10:12 PM

#

you might have to use a Stop Movement node before turning on the physics.

void cobalt Jun 7, 2020, 10:13 PM

#

hmm hold on

#

i put stop movement in

#

but it only stops for a second after i hit it rather than when it dies

Trying to make my ship rotate multiple times, how come it's only doing a 180° rotation? :/

📎 unknown.png

thin rapids Jun 7, 2020, 10:17 PM

#

its rotation 540 degrees

#

but the rotation is instant

#

so you cant notice it

#

and it looks like its 180 degrees

cerulean pivot Jun 7, 2020, 10:18 PM

#

nope, just made it rotate over 5 seconds and it's still rotating 180°

thin rapids Jun 7, 2020, 10:19 PM

#

do the rotation in a timeline

#

and see if it is just 180

any 1 has any experience attaching a camera to the head bone?

#

it works fine for me in the editor but in game its like its not attached

thin rapids Jun 7, 2020, 10:23 PM

#

it works fine for me in the editor but in game its like its not attached
@celest oar with in game you mean in a packaged build?

celest oar Jun 7, 2020, 10:23 PM

#

no just play in editor

#

when im in the bp viewport it works as expected, as soon as i play in the editor its like the attachment never happened

simple lantern Jun 7, 2020, 10:24 PM

#

Hey all, I dropped a copy of my ThirdPersonCharacter BP into my scene with an Enable Input connected to BeginPlay in it, and expected this mannequin to copy my players movements but instead nothing is happening. Any obvious reason why this is the case?

trim matrix Jun 7, 2020, 10:24 PM

#

Can you send screenshots sonicphi?

celest oar Jun 7, 2020, 10:24 PM

#

theres nothing much to see really

#

its jsut a construction script that has a start node connected to attachtocomponent with the camera as target and the mesh as parent

trim matrix Jun 7, 2020, 10:25 PM

#

I'm trying to see what youve done wrong. As if you just put the camera under the mesh in the components screen and select the bone you want to attach it to, it should be working.

celest oar Jun 7, 2020, 10:25 PM

#

@simple lantern pawns needs to be possesed to move

#

@trim matrix i didnt do that, but in theory i am doing the samething but with an attach node

trim matrix Jun 7, 2020, 10:26 PM

#

Oh. Ive never done it with the attach node.

celest oar Jun 7, 2020, 10:26 PM

#

also it works in the editor it should work in the game

#

thats why im confused

simple lantern Jun 7, 2020, 10:27 PM

#

@celest oar Is that based on how pawn movement is calculated? because I could easily create other BP's in my scene that move based on my input, like doors.

static charm Jun 7, 2020, 10:27 PM

#

Inputs actions and axis events all have consume input enabled by default. which means only one actor will receive any of those inputs. you have to disable the setting inside each node in all the blueprint for the input to work on any actor.

sonic crescent Jun 7, 2020, 10:27 PM

Hi guruz, What is the best way to have a spaceship that move with an inertia, like a little lag because it's heavy?

void cobalt Jun 7, 2020, 10:27 PM

#

ok so it works when the target is static mesh?

trim matrix Jun 7, 2020, 10:27 PM

#

Maybe its an issue of restarting the editor. Sometime restarts solve stupid problems

celest oar Jun 7, 2020, 10:28 PM

#

@simple lantern yes its not the same

#

i can try to restart

#

doesnt hurt

#

but i doubt it

@static charm let me try that, thanks

thin rapids Jun 7, 2020, 10:29 PM

@celest oar wait does that means its working or the now was a typo for not

Is there a way to add input to a character to drive it's movement without possession? Like feeding it a boolean instead of keyboard inputs?

Hey all!

I create an ActorComponent C++ class. Inside that class there is a public UFUNCTION called PlayFootstep().

That same actor's animation blueprint I have created some anim notifies for when the player "steps". In the event graph, I reference these anim notifies, and that anim notify calls my "PlayFootstep" function from C++.

When I try to compile the blueprint, it fails. I guess I need a reference to the target? What does that mean? How do I fix that?

#

tight venture Jun 8, 2020, 1:45 AM

#

After a few hours of debugging, I finally came upon an important discovery, so I thought I'd share it with y'all:

#

RandomFloat gets called twice!

The value sent to the > node is not the same as the value that Foo is being set to.

📎 unknown.png

#

Would've saved me a few hours' time if I'd have known that ahead of time.

#

That was an arbitrary example, of course. The point being:

The value obtained from a function call is not "saved" at the reroute pin. It is obtained anew from a fresh call to the function.

tight schooner Jun 8, 2020, 1:50 AM

#

yeah, that's how "pure" functions differ from executed functions

tight venture Jun 8, 2020, 1:51 AM

#

Do you know exactly the conditions under which this is true? (I just discovered this minutes ago)

#

Are there any times when the same float would be sent to > and set to Foo?

#

e.g. a user-defined function as opposed to a built-in one, in a macro, etc

#

since a macro is just an expansion, there might be times when this wouldn't apply to them, right?

tight schooner Jun 8, 2020, 1:53 AM

#

I would imagine that a random float inside of a macro would roll a new number for every node the macro's connected to

#

but if you put the Random Float node into an executed function (i.e. has exec pins) you can re-use the rolled value

#

cuz the function only executes when you tell it to

tight venture Jun 8, 2020, 1:54 AM

#

Very sneaky... I would've noticed that in a second if it were written in code 🤨

#

ahh.... good point @tight schooner

#

That was the answer I was looking for. That's what makes it call RandomFloat twice

tight venture Jun 8, 2020, 2:22 AM

#

@tight schooner So I assume that the same is true for this?

📎 unknown.png

#

The value being checked > 0 is not the same as the value being set to Foo, correct?

#

Gotta be the same. Even sneakier when it's hiding behind another node like that

tight schooner Jun 8, 2020, 2:27 AM

#

I haven't done extensive testing on how executed functions work... my vague impression is that each executed node, such as that Branch and that Set in your screenshot

#

re-executes each of the "pure" functions feeding it

#

ok, I did a test and answered the one thing I was wondering about pure functions...

📎 random1.png

#

📎 random2.png

#

so yeah, each executed function... executes... each pure function connected to it once

Hey guys I have a question on a simple blueprint function. I have am making collectables and have a icon in the HUD that I need to change opacity based on the collision of collecting the item. I put a boolean into the box collision of the item and tested it with print string and it shows that collecting the item changes the boolean to true. So that part works. Now I need to have my Item Icon in the HUD that is almost invisible on the top left of the screen recognize The boolean is changed and change the icon opacity. How would I set up the opacity change based on the boolean changing?

I feel like this is something that they should scream at you in your first introduction to blueprints. Very confusing, visually.

tight schooner Jun 8, 2020, 2:35 AM

#

yeah I get the impression that everyone new to programming learns this lesson by connecting a Random Float node to multiple things, lol

tight venture Jun 8, 2020, 2:35 AM

#

hehe

#

Look at #gameplay-ai to see what I actually was going through when I discovered this

#

@rugged violet You'll need a material parameter to do that.

#

Go into the icon's material, right click on the opacity pin and choose "Promote to Parameter". Then you can get the material and set its parameter in a blueprint

How can I set an angular velocity on a component relative to its rotation?

tight schooner Jun 8, 2020, 3:17 AM

#

Combine Rotators node if you're trying to make a rotator relative

sweet onyx Jun 8, 2020, 3:18 AM

#

Specifically, if I want an object to spin around Z, it looks fine when its Z points up, but it's all wrong when its Z is pointed anywhere else but up

#

I was using Set All Physics Angular Velocity

#

combine rotators?

#

Hmm

#

That's probably it, let me try

tight schooner Jun 8, 2020, 3:19 AM

#

If you have some world space rotator, combine it with the actor's rotation (or the component's worldspace rotation) to make it relative to that thing

sweet onyx Jun 8, 2020, 3:19 AM

#

Set All Physics Angular Velocity doesn't take a rotator, it takes a vector

tight schooner Jun 8, 2020, 3:19 AM

#

Oh ok. Rotate Vector node I guess

sweet onyx Jun 8, 2020, 3:19 AM

#

When I drag the node, it's converted via GetRotationXVector, not sure if that's right

tight schooner Jun 8, 2020, 3:21 AM

#

I'm not familiar with that node so idk what it expects. Generally speaking, use Rotate Vector to make a worldspace vector relative to some thing's rotation

sweet onyx Jun 8, 2020, 3:21 AM

#

I'll give that a shot

#

Tried a bunch of stuff, but none of it worked

#

Tried to rotate its rotation by 500 on Z, and set that directly, no spin

#

Tried RotateVector, no spin

#

If I pass in the current angular velocity into rotate vector, it's funky again

dense mantle Jun 8, 2020, 3:29 AM

#

@sweet onyx Have you Tried to apply to it ???

#

torque that is lol

sweet onyx Jun 8, 2020, 3:29 AM

#

@dense mantle torque? hmm

dense mantle Jun 8, 2020, 3:30 AM

#

@sweet onyx what is angular velocity ??

sweet onyx Jun 8, 2020, 3:30 AM

#

@dense mantle how fast it spins

dense mantle Jun 8, 2020, 3:31 AM

#

@sweet onyx so you need torque to get a motor going to move the car start there

sweet onyx Jun 8, 2020, 3:32 AM

#

well... using apply torque is closer to what I want

dense mantle Jun 8, 2020, 3:32 AM

#

@sweet onyx is it s tire or what

sweet onyx Jun 8, 2020, 3:32 AM

#

the specific use case is a thrown disc

#

the idea is, you throw it, it spins

#

with set angular velocity, that angle seems relative to the world, so if you throw horizontally, spinning around Z looks fine, but throw vertically and it looks like throwing a mario coin

dense mantle Jun 8, 2020, 3:33 AM

#

cool so torque will spin it and the inpluse you give it will throw it

sweet onyx Jun 8, 2020, 3:33 AM

#

adding torque is way better, but instead there's a wavyness to it that's also bad

#

rather than just a straight spin

dense mantle Jun 8, 2020, 3:33 AM

#

@sweet onyx lock the verts

#

the disk needs to be wrapped so you can lock the disk to z axir rotation and the use the wrapping bp to add it back for effect

sweet onyx Jun 8, 2020, 3:35 AM

#

wrapped?

#

it's a static mesh actor

dense mantle Jun 8, 2020, 3:35 AM

#

bp contains the disk

tight venture Jun 8, 2020, 3:35 AM

#

So @tight schooner, in your opinion, is there any danger in doing something like this? The only danger I can think of would be related to thread-safety (if the Influence gets set in a different thread) but I don't know enough about UE's thread handling to be able to speculate on that.

Basically, should I use local variables for anything that comes out of a pure function, to ensure the value is saved, instead of branching off the output pin multiple times?

sweet onyx Jun 8, 2020, 3:36 AM

#

@dense mantle the idea is, you throw, it keeps going in the direction you throw it, at the rotation you threw it at, but spinning

#

like a thrown frisbee, basically

tight venture Jun 8, 2020, 3:37 AM

#

@keen garden I'd be interested to hear if there's an answer to that myself. AFAIK, this discord server is the missing chapters in UE's documentation.

dense mantle Jun 8, 2020, 3:37 AM

#

@keen garden start with the live streams that un real put out they have some great training

tight venture Jun 8, 2020, 3:37 AM

#

^ I disagree, somewhat.

sweet onyx Jun 8, 2020, 3:37 AM

#

I got the first part by disabling gravity when thrown, and the second part with the set angular velocity, but it has that side effect depending on how it's rotated when initially thrown

tight venture Jun 8, 2020, 3:37 AM

#

UE's live stream videos are terrible

#

There are other youtubers that produce much better, more concise videos

keen garden Jun 8, 2020, 3:38 AM

dense mantle Jun 8, 2020, 3:38 AM

they are great at giving a direction of what is there to use ... there are too many changes for a "book" to be relevant that long

tight venture Jun 8, 2020, 3:39 AM

When it comes to figuring out more details on a specific node, the WTF Tomatoes guy has a short video explaining just about every single god damn one.

sweet onyx Jun 8, 2020, 3:40 AM

@dense mantle I don't see a way to lock the rotation in a BP node

sweet onyx Jun 8, 2020, 3:40 AM

#

I can lock rotation in the details pane, but I only want it locked when thrown

keen garden Jun 8, 2020, 3:41 AM

how do I set a % chance in an array so that I can change how often things spawn

#

@dense mantle I don't follow

tight schooner Jun 8, 2020, 3:43 AM

#

@tight venture I don't fully comprehend the question or your screenshot... The way pure functions work, conceptually, is they'll always give you up to date information. So for everything you connect Is Valid (boolean) to, it will re-check if the thing is valid and produce an up to date answer.

tight venture Jun 8, 2020, 3:44 AM

#

@tight schooner exactly. So what if the object becomes valid in between execution pins? Only reason I could see that being possible is via multi-threaded stuff, which, if it does happen, is hidden from you

#

I think we're supposed to presume that everything except events are single-threaded, right

#

errr... technically, maybe even that is single-threaded too

#

I guess what I'm saying is... what would be the point of needing to check for up-to-date information if there was no chance of it changing between now and then?

tight schooner Jun 8, 2020, 3:46 AM

#

Yeah if you set up a situation where it becomes valid in between, it'll produce a different answer.

Also yeah all game logic (and physics) runs on one thread called the "game thread". There is a BP multithreading plugin I've heard but I have no experience with it

tight venture Jun 8, 2020, 3:47 AM

#

That situation we were talking about earlier is so deceptive though... it would basically only occur (with any relevance) in situations like getting random values. GetActorLocation will probably produce the same value between a few execution pins

tight schooner Jun 8, 2020, 3:48 AM

#

And yeah, if you wanted to save performance in some data/execution-heavy script, like if you're doing thousands of loops, you could save a predictably static pure function output to a variable or something.

tight venture Jun 8, 2020, 3:48 AM

#

For example, anyway

#

yeah, good point

#

@pure blade you'll have to clarify further if you want anyone to answer

tight schooner Jun 8, 2020, 3:51 AM

#

If pure functions didn't re-run for every node it's connected to, then it would add some ambiguity over how up-to-date the information is. I have no prior programming experience so I can't speak to C++ and whatnot, but would assume BP's approach is that execution wires drive execution. If it doesn't have execution wires, then you don't get to control when a function produces new data.

#

As an approach there's is a discernable logic to it

#

If it didn't work that way, then people would have the opposite confusion over when pure functions are updating their outputs

@tight venture thx

tight venture Jun 8, 2020, 3:54 AM

#

@tight schooner I agree. I was just fooled by my intuition based on how it looked in a blueprint.

#

I have C++ experience. Quite a bit of it. I find myself kind-of translating, if you will, blueprint schematics into code, in my head. I was just translating it incorrectly.

tight venture Jun 8, 2020, 4:23 AM

#

@slender venture Probably. I'm no UE guru, but event tick, unless you've set it to behave otherwise, is called every frame. You want to keep as much out of EventTick as possible.

#

In all practicality, though, just run it. If it runs slow, that's probably the culprit. If not....... who cares...?

#

Anyone know how it is possible for a physics object to become launched outside of a sealed room?

I have a kitty playing with balls of yarn, inside what is essentially a cube with no way out. Yet, quite often, my kitty will bat the yarn ball around, apparently so fiercely that it somehow teleports through the walls or the ceiling.

Is there something I'm missing? Maybe something to do with sweep motions?

#

I have the collision settings basically correct, I think... If the kitty doesn't bat it very hard, it banks off the walls like it's supposed to.

#

I just realized I should post that in #legacy-physics but the answer probably has more to do with something basic so I'll let it simmer here for a bit

are “input action” things expected to work if you have them in the blueprint for an arbitrary actor, or only pawns / player controllers? mine aren’t working but I’m not sure if it’s because of other weirdness (the inputs are mapped to VR controllers) or because what I’m doing isn’t even right in the first place

Hey all, could someone help me with transferring my player controller inputs to an AI character that would mirror all of my players movements? My first thought was to just copy the ThirdPersonCharacter BP and place it in my scene, and enable input on it, but that didn't work. I tried disabling consume input on all the InputAxis nodes, but that didn't do anything either. Some suggestions after coding suggested just feeding the players actions to the ai character, but I'm not sure how to go about that. Any advice would be helpful

deep elbow Jun 8, 2020, 6:12 AM

#

you could use event dispatchers to run the same commands from the player controller - in your AI just bind some events to the controllers input events, or literally just set a ref to the player in your AI when it gets created and have your input events on the player run similar things on the ai

simple lantern Jun 8, 2020, 6:37 AM

#

@deep elbow Thanks for the reply. Since event dispatchers are a little above me right now, I'm trying to accomplish it by casting to the mirroring AI and setting a custom event. Here is the player's BP

📎 unknown.png

#

and here is the receiving AI's BP

📎 unknown.png

#

Not working though, and since I still only have a beginners idea of how this works i'm not sure whats going wrong

#

to be specific I'm getting a cast failed

deep elbow Jun 8, 2020, 6:46 AM

#

yeah, you are getting the player character and then casting to another actor, which is not the player

#

does that make sense?

#

when you get player character it returns the character that is possessed by the player controller

#

if you want to use casting you need to get the actual actor that is the shadow, you need a direct reference to it

#

this is why dispatchers would be useful to you because you wouldn't need to know where or what that is, but the shadow would just bind events to the player character, but if you want to use casting you need to, at begin play or when the pawn is possessed, or when the shadow is created (is it spawned dynamically from gameplay?) you create a reference in the player pawn, and plug that into the cast object

#

@simple lantern

#

casting is less like fishing where you throw out a line and hope to get something, and more like Scorpion in mortal kombat where you throw a line directly at something you know is there

lilac lance Jun 8, 2020, 6:52 AM

@simple lantern dont be scared of dispatcher.
Just create it in the character, and in the mirrored one, type bind "name of dispatcher" and disable content sensitivity for it to appear. Bind it on begin play of mirrored.

You can add inputs and outputs to the dispatcher.

#

I hope i said it right.
I may be slightly wrong on something.
I cant check now.

he needs a reference for the player in his mirrored character tho right, can use get player character and cast to that

right, can you try compiling the blueprint that has the dispatcher, and then right clicking your custom node and selecting refreshnode?

yeah having problems finding the updated version:(

simple lantern Jun 8, 2020, 8:15 AM

#

So if i'm binding an event to an event dispatcher, I need to cast to the BP that contains the event dispatcher. If i'm casting to that BP to access the dispatcher, what's the point of even using a dispatcher? why not just create a custom event instead?

#

I thought the benefit of an event dispatcher is that it is it's own version of communication that any BP can tap into and access without direction communication. but if i'm casting just to access it I just don't see the point

what glaringly obvious thing am I missing here..

deep elbow Jun 8, 2020, 11:16 AM

#

@trim matrix you can double click wires to create reroute nodes, alternatively collapse sections onto a child graph, you can also use custom events to reroute the flow; or the best practice imho, is turn off the blueprint grid, and make stuff readable at a glance but avoid getting hung up on tidy blueprints, it sucks away time and accept nobody will ever ever see it when playing your game. as long as something can be followed by another developer without untangling then it's fine

maiden wadi Jun 8, 2020, 11:28 AM

@dim robin Not sure how you're handling this with just what you've shown, but all you're checking is that an actor that can be cast to a BP_Pawn is passing the checkpoint. There's no checks about whether it's locally controlled or anything multiplayer. So this means that on any person's machine, anytime that a BP_Pawn that is controlled by anyone, even an AI controller passes a checkpoint going the right direction, it'll clear that checkpoint.

dim robin Jun 8, 2020, 11:29 AM

that's exactly the point! should I tell inside the checkpointbp (the one with overlap event) to check which player is going through?

#

The only thing I was thinking about was to set a different pawn (maybe a child of the main pawn) for each player, and duplicate the checkpointbp for each player, changing the overlapping actor with every single pawn children. that ideally should work but I believe it's the worst way to do that

Change the visibility of the checkpoint in the scenerender. There may be a better way though. I'd check the multiplayer channel. Someone there might have experience in Coop that can help.

Specifically this part:

"The shortcut method (which should work depending on how specific that 100ms window needs to be) is a VInterpTo Constant node.

basically the input that's given to object A i want to then get passed to object B after a delay

elfin hazel Jun 8, 2020, 12:12 PM

#

there's no way you'd solve that with a delay. If you want an exact trace, every tick you need to cache the leading actor location. And every tick the follower needs to get the cached location of x time ago.

#

Or well there's also the 'chrono cam' system.

I don't have a great top-of-head answer for that short of making a custom struct that has your inputs and also the timestamp, and saving to an array every tick for ultra accuracy. (Then using the timestamps to interpolate the values and reconstruct the inputs at any arbitrary point in time.)

#

It'd be a data intensive approach for sure

#

But if you could do with less accuracy you could add to the array every 100ms instead and interpolate entries to get a particular time

#

I never tackled this problem myself so there may be a smarter approach to this...

simple lantern Jun 8, 2020, 12:17 PM

#

I've looked around a bit and it seems to always circle back around to creating a 'buffer' with arrays

#

I was hoping for something simpler though since I don't really have the knowledge to put that array set up together :/

glacial eagle Jun 8, 2020, 12:21 PM

#

The only way you can really make it work reliably is keep a short history buffer that you store the location in each frame (and timestamp each entry)

#

You can get an interpolated position between two samples to get an "exact" 100ms-in-the-past time.

#

Or just use the sample that's closest

simple lantern Jun 8, 2020, 12:22 PM

#

What if there was a workaround by using the world position to generate a spline, and have the second actor follow that?

glacial eagle Jun 8, 2020, 12:23 PM

#

That still doesn't help when it comes to being exactly 100ms in the past

#

No different to interpolating the position directly AFAIK

simple lantern Jun 8, 2020, 12:23 PM

#

right

elfin hazel Jun 8, 2020, 12:25 PM

A spline is just an array of transforms really. it's pretty much the same method. Maybe you would have some more functionality to access from splines but that's about it.

tight schooner Jun 8, 2020, 12:27 PM

#

The spline method won't be less complicated ... You still have to manage points and interpolate values cuz splines don't recognize points as being a fixed time interval thing out of box. (My current project uses splines that way and I had to make some custom functions to do point-by-point traversal.)

elfin hazel Jun 8, 2020, 12:28 PM

#

But I think that what it boils down to is that you got to implement your own system, and to do that you need to be somewhat comfortable with the parts you're working with (arrays, transforms, blueprint communication). And you should work on something that is simpler but shares some of those parts so you get how they work.

It seems like something that lends itself more to CPP-implementation tbh if you're able to do that. Array manipulation in BP (especially each frame) can be painful.

The lag comp method I've done works pretty well though. At the end of each frame (or after object moves), store the history item with the current world time seconds as a timestamp.

@jaunty dome Open a gate to a tick that does it, or set a looping timer.

jaunty dome Jun 8, 2020, 1:07 PM

which node is that again ?

maiden wadi Jun 8, 2020, 1:07 PM

#

Which one? They're different things.

jaunty dome Jun 8, 2020, 1:08 PM

#

well how to use a ticking gate, and how to set a looping timer

#

whichever is better on performance side

simple lantern Jun 8, 2020, 1:08 PM

#

@simple lantern I did something similar not too long ago. Just in reverse. Created a 'recall' effect that lerped the player backwards over their last five seconds worth of movement. Was rather fun to implement.
@maiden wadi sounds awesome. was it in BP or C++?

maiden wadi Jun 8, 2020, 1:08 PM

#

Probably timer. Since it's not every single frame.

simple lantern Jun 8, 2020, 1:09 PM

#

@jaunty dome the node is Gate

maiden wadi Jun 8, 2020, 1:10 PM

#

@jaunty dome Try this.

#

On press it'll create a timer and loop it every 0.05 seconds. On release it'll clear and stop looping the timer that's calling the line trace function.

#

@simple lantern It was in blueprint. I'll see if I can't find the project really quick.

simple lantern Jun 8, 2020, 1:14 PM

@maiden wadi cool thanks

jaunty dome Jun 8, 2020, 1:16 PM

@maiden wadi I was exactly doing that 😮

#

thank you

#

one issue tho

#

i'm using a timeline to make a smooth "zoom" effect on camera

#

using Play and Reverse inputs

#

how would one go about that in the "LineTraceStuff" event ?

#

or maybe I should do the camera zoom BEFORE the event ?

#

even with that I only have one input after it hummmm

maiden wadi Jun 8, 2020, 1:20 PM

#

@simple lantern So, bearing in mind that I'd probably do a few things differently these days, like make the Vector/Rotation arrays into a single array of structs. This is also single player. This is what I was doing with that.

a mesh started cloning itself. I have an interaction that rotates it, and it clones itself on top of rotation. what can be the cause?

#

now I understand, it's the child actor, for some reason when I spawn stuff with child actor, there's two of them.

Hey everyone ! Is it possible to keep modifications made to blueprints when I exit my playtest ?

For example, I spawned an object using ingame UI, and I want that object to stay there when I exit the playtest.
Or, I changed some settings in my blueprints ingame, and I want them to stay the same when I exit.

#

Just need a way to keep everything the same and not reset the scene

maiden wadi Jun 8, 2020, 1:37 PM

#

@crude timber Blueprints are just that, blueprints. They're a blueprint of the object you create from them. They don't actually change. What you're changing in your playtest is an instance of the object created from those blueprints. As for those. I think there's a keep simulate option for the editor somewhere if you wanted to use that, or you're going to need to rely on savegames.

elfin hazel Jun 8, 2020, 1:44 PM

#

You could look into Editor Utility objects, I bet there's a way to change the value of an object in PIE, and then using Editor Utility apply it to the class or maybe even instance object in the scene.

gilded pebble Jun 8, 2020, 1:46 PM

#

Hey, is it possible to rotate a socket on a skeletal mesh using blueprint?

elfin hazel Jun 8, 2020, 1:51 PM

#

@gilded pebble Doesn't seem to be. But you could attack a scene component to the socket. And now the scene component is your new socket that you attach things to. And you can manipulate it. But I would use it lightly, or stress test it, since the more bones and sockets the mesh has, the more transforms the animation needs to update.

elfin hazel Jun 8, 2020, 2:02 PM

@jaunty dome hmm I always forget how I do that. If the widget is on a canvas panel, then you can get its slot as canvas slot and get its position. But I bet you'll get some weird offset, so you probably have to scale it by dpi. You got to google this yourself tbh.

jaunty dome Jun 8, 2020, 2:02 PM

nvm Robin i got it

so say if I have an actor that when the character overlaps it will add a 1 to an int and if I have multiple of the same actor how to I get the highest int (e.g. actor 1 is 4 and actor 2 is 8 )?

elfin hazel Jun 8, 2020, 2:35 PM

#

@simple lantern You can get the Last Index of an array. Though, the question is if you want that. Since you want the follower to follow after a certain time, maybe the leader object should inform the follower when the array is full or something?

simple lantern Jun 8, 2020, 2:39 PM

#

@elfin hazel the way I have it set up, i'm trying to get the follower to move to the oldest array index location. Object A set's a variable "UpdatedLocation", and object B gets that variable and feeds it into it's world location. I just don't know what index to feed into UpdatedLocation :/

#

whatever index I set that variable as, it seems like the entry data gets frozen. Like the follower will move to the index just fine, but as the array fills up and all 30 indices are getting updated and moving through the array chain, the follower location doesn't update

elfin hazel Jun 8, 2020, 2:41 PM

#

well, if you're Adding to an array, zero index will be the oldest. You can Insert at 0 index, pushing the older ones and then the last index will be oldest.

How do I change actor transparency having the actor object reference?

maiden wadi Jun 8, 2020, 2:56 PM

@cinder stratus You can't actually affect an actor's transparency. Just whether it's visible or not. To change transparency, you need a static mesh in the actor with a material that can change it's transparency.

Can I change the material of the object via blueprints?

Of course. Just get a reference to the mesh you want to change it on and set the new material.

Is there any good way to handle "Apply Damage" if your actor is already handling Point and Radial damage events separately?

#

Apply Damage only triggers the Any Damage event, but the point and radial damage functions also trigger that... which would cause those to get handled twice because there's no way to tell which kind of damage it was in the Any Damage event...

#

(this isn't really a huge issue, I'm just using point damage for "generic" damage atm, but figured I might as well ask to see if I missed anything)

maiden wadi Jun 8, 2020, 3:51 PM

#

@earnest tangle The DamageType should be able to differentiate that for you.

I think. I might be mistaken, let me look.

#

Oh, my bad. Was thinking damage types, not the application function.

earnest tangle Jun 8, 2020, 3:53 PM

#

It's not the worst idea tbh, I only wanted to use apply damage in some special cases

so I could have a DamageType_Generic for that purpose, and then if that's not used with with any damage, the event just gets ignored :)

@lone vine if you know there are only a certain type of Actors you will be scanning for you can use a custom TraceTypeQuery to limit the results to just that class

than go to your actors set collision type to custom, and add custom collision trace type*

Can anyone recommend a good method for having the main character provide valid, yet random tips to the player depending on the situation? Example: maybe the character hasn't broken a hidden wall in the environment, and the character would say, "hey, maybe I can break that." Or, "what's that over there?". My initial thought was linking a trigger box to the state of that hinted object and it would activate/deactivate as needed via dispatcher bind. Is there a better way to manage this?

zenith scarab Jun 8, 2020, 5:17 PM

Yes I would do something similar.
Having an overlap box on the specific actor with an array of tips.
After a specific time in the overlap and nothing happening it could start displaying the tips

thin rapids Jun 8, 2020, 5:23 PM

you could also make sphere traces or box traces and see if the object that has been hit has a certain tag

daring summit Jun 8, 2020, 5:57 PM

#

No worries :) Just create a new timeline (right-click in graph, create timeline). Create a new function within it. Right-click to add new keys (add 2 for now), to set your float start value and time and end value and time. This basically will increase (or decrease or whatever your float is told to do within the timeline) the float value over time. You can then link your output value from the timeline to the set rotation of your turret

Good Evening :)

I am making a building game, whats a good way to structure data/ objects so the player can choose which items they want to build with?

I currently have an array that cycles but the items dont remeber which number in the array they are so saving is impossible... any help appreciated. Even suggestions of what to google will help

maiden wadi Jun 8, 2020, 6:40 PM

#

Hard to say without more information. How many building parts are we talking about? What kind of UI are you looking for for picking building pieces? etc.

dim kiln Jun 8, 2020, 6:42 PM

#

@maiden wadi thanks for replying :)

Maybe about 100 in total, I just need a way to give each item a unique identifier, currently I have 3 items working as an array

📎 unknown.png

#

but once they are build unreal calls them all 'Buildblock' with no way to tell which peice they are

#

so creating a save file with their locations is proving problematic with all the same names and the same actor class

maiden wadi Jun 8, 2020, 7:00 PM

#

@dim kiln Well, personally if you're going with that many buildings, I would do this off of a datatable. Make a struct that contains everything you need to initialize this buildings defaults, mesh, material, etc. I like renaming the rows in my Datatables to be a simple 0 based number that I can use as a lookup ID. But to simplify what I mean.. Say you have three building types. A floor, A Wall, and a Roof. What you might do is create a struct that contains the mesh type, materail, maybe a transform or location for a local offset like if you're building on a grid. Then you can create the building with these from your BuildBlock. Make it have a StaticMesh component and set the static mesh to the one from the struct, then the material to the same static mesh component. Set the local offset if you need it. And also in this Buildblock have a name or integer that you can use to identify which building type this was in the datatable. Then when you save, you save the location, that it was a BuildBlock class, and that ID. Then when you load, all you need to do is spawn a new Buildblock at the save location, and recreate it with the datatable ID that you saved it with.

#

Hoping most of that made sense.

#

Of course you can add a lot of other stuff to the struct that makes up the datatable too. Maybe build costs, or requirements. All stuff you might use when first creating this building.

dim kiln Jun 8, 2020, 7:04 PM

#

thank you so much ❤️ I will read up about data tables. Assigning an ID is the bit I am most unsure abou

maiden wadi Jun 8, 2020, 7:06 PM

#

I'd probably go with integers myself. Just make an integer in the buildblock and set it to the same ID from the datatable. Just needs to be something that you can use to look up the assets in the datatable later for loading.

dim kiln Jun 8, 2020, 7:08 PM

#

yea should be nice for cycling meshes as well with simple of adding 1 or -1 to the ID

#

I am correct in thinking the buildblock will basically be empty and then just assign the mesh from the table? @maiden wadi

maiden wadi Jun 8, 2020, 7:09 PM

#

Correct. But it still needs an empty StaticMeshComponent.

This is odd... https://gyazo.com/310d5143e7c7cb878be4310798bbd539
how can the exec lline out of the loops finished be lighting up, when the input to the loop is not? Those two wires should always be running at the same time

I'm unsure if this is a visual quirk, or if there is some useful meaning here that I'm failing to grasp...

Hard to say. I tend to not trust or use a lot of the in editor debugging tools. I've had very little problem using general logic and print strings for pretty much all of my debugging needs.

round idol Jun 8, 2020, 8:26 PM

#

Heh...Can anyone recommend a "trick" or something I could do not to have multiple spawned units do "synchron dance"? They are playing the same animations on the same meshes, they all move at once and it looks like a 90s J-LO clip 😄

maiden wadi Jun 8, 2020, 8:28 PM

#

You're spawning them all at the same time?

tight schooner Jun 8, 2020, 8:31 PM

#

add a breakpoint to a node and step through your logic node-by-node

#

that's another way to examine your execution flow

lyric urchin Jun 8, 2020, 8:32 PM

#

@vital prism yeah i would use a print string to see if the finished is actually always running or not. ive come across a lot of bugged exec lines myself. once a BP becomes larger, the traces seem to become more visually unreliable

lyric urchin Jun 8, 2020, 8:48 PM

#

im trying to add components to a BP based on how many objects there are in a public array. i want to be able to edit each of these components in the editor. anyone know how i could do this?

#

#

ive tried adding a static mesh component in the construction script, but they dont appear in the editor as i add to the array

I'm trying to create a heartbeat flashing effect. The closest I can get tinkering is plugging a sine into a cosine half the value. Can anyone recommend a good way to emulate a heartbeat style pulsing?

#

I thought about combinging two sines somehow, one with a minor delay, but can't think of the node to use to do so

round idol Jun 8, 2020, 9:04 PM

#

@maiden wadi sry, missed that. Apparently yes, it's a jRPG so units face each-other in a battle map

maiden wadi Jun 8, 2020, 9:06 PM

#

Dunno. Somewhere, probably somewhere in the animation blueprint or something you'll need to start a timer or something with a random float and start the idle animation after that.

round idol Jun 8, 2020, 9:07 PM

#

but I just found out I've ignored a huge problem for a long time and i have no idea what to do, so i kinda lost my interest in finishing touches - this is a game breaker 😭 Idk how to remove hand-placed encounters from the world map upon winning a battle...Idk how I've missed this, now I can't find a way to do it...Any ideas would b wonderful. Otherwise I'll have to spawn all encounters procedurally which is inconvenient in many game situations 😦

#

@maiden wadi it's the only thing I've thought about, but wanted to ask, there is still about 80% of engine nods I never used 😛 Thanks, will go with a random delay of 0-1 sec or something, that should b enough range

@trim matrix This works really well in combination with what I had, thank-you!

#

📎 unknown.png

#

For anyone else 🙂

round idol Jun 8, 2020, 9:13 PM

#

@trim matrix Question is how do I ref that actor that "knows".
I've tried reporting encounter to GI before switching to battle map as dummy.
The ref gets passed to the Battle map PC and if the battle is won, Battle PC passes it back to GI marked as "defeated".
GI then adds it to an array of "to be destroyed upon world level load".
Problem is, when the "new" world map gets created, the dummy no longer matches "newly created" (hand-placed) actor ref (ofc...) and the "to be destroyed" array contains an index of the right type but registered to a different level, so !=

#

Oh wow, I'm an idiot - would it work if I did the same thing with a bool or anything else which gets passed on to GI?!

#

@trim matrix but they "knew" me in the last "session" as far as they're concerned, they spawned a-fresh...Only some independent data permanently in the GI would do...Right? or am I still being retarded? 😛

#

and why do u say "we hacking"? Shouldn't this be simple? :/ Didn't even think of it and I have the whole battle pre-alpha-test ready lol...Even did UI for it to be tested for bugs/ballance/fx/anims 😦

#

and now i feel like a dodo bird 😐

#

damn it! Spawn procedurally from DT to targets/pointers then? :/ Any ideas? I can't be the only one getting smacked by this...

HELP. I have a collectable and i want it to trigger a opacity change on a HUD icon when collected. This is my collectable, the letter S. set up like this. When i collect it it says true on screen. SO it appears it is setting my boolean variable correctly. How would I connect that to the HUD opacity change. I have tried a few ways and cant seem to get it right.

round idol Jun 8, 2020, 9:47 PM

#

@rugged violet An easy way is to play an animation for the letter you want which brings opacity to the value you want.

#

Player Call Function Event pickup --> (Widget has the event pickup called by the player) --> Event Pickup - Play animation

Anyone know how to access an action's default key bindings? Alternately, anyone know how to reset an action's current bindings to the project default?

rugged violet Jun 8, 2020, 9:51 PM

#

@round idol Im modding a map for a game i did not make and Im not accessing the player at all so my map doesnt break when they change things as the game has not come out of BETA yet.

round idol Jun 8, 2020, 9:53 PM

#

@rugged violet irrelevant man, just make an event on the widget which you call from the BL_S (before destroying BL_S ofc). The event on the widget plays an animation which changes opacity

rugged violet Jun 8, 2020, 9:54 PM

#

Oh ok. Ive never made an animation before so its all new to me.

round idol Jun 8, 2020, 9:54 PM

#

Then just get the letter and set it's opacity in the widget blueprint

rugged violet Jun 8, 2020, 9:55 PM

#

Thats what i wanted to do but i messed up somehow.

round idol Jun 8, 2020, 9:55 PM

#

Make Image518 into a variable and upon the event, drag a get from the var, type in color and "color and opacity" node will pop up. break the struct with right-click and set opacity

rugged violet Jun 8, 2020, 9:56 PM

#

Ok. How do i make the image to a variable?

narrow kelp Jun 8, 2020, 9:57 PM

#

@rugged violet if you want to be very dirty, you can GetAllWidgetsOfClass

#

but it would be better to have a reference somewhere

@rugged violet Like I was saying, you need a reference to your widget

#

if you don't have one already, you can GetAllWidgetsOfClass

📎 unknown.png

round idol Jun 8, 2020, 10:04 PM

#

Ok...nvm

narrow kelp Jun 8, 2020, 10:04 PM

#

you might need to do something like this, replacing widget_status with your widget

#

then you can do what claudiushwartz was saying and set the variable

rugged violet Jun 8, 2020, 10:06 PM

#

@round idol thank you for trying. this may lead to a solution in the end. Im new to blueprints as you can tell. @narrow kelp I tried to set a boolean before destroying the collectable and that seems to work. How do i check the boolean and have that set opacity in the HUD?.

narrow kelp Jun 8, 2020, 10:07 PM

#

the more correct way of doing it would be to make a function on the HUD

#

that is called by the pickup when it overlaps or w/e

#

a function or event

#

In other words, when your pickup item is picked up, it asks the widget to do whatever it needs to

#

and the widget sets the opacity of your image

rugged violet Jun 8, 2020, 10:09 PM

#

Sounds legit. lol. How do i do that? I tried this.

📎 PlayerHUD_Widget_6_8_2020_6_07_25_PM.png

narrow kelp Jun 8, 2020, 10:09 PM

#

Tick is an event that is called basically every frame

round idol Jun 8, 2020, 10:09 PM

#

@rugged violet ok...lol, stop with that event tick already. Just do exactly as I say:

vital prism Jun 8, 2020, 10:09 PM

#

@lyric urchin Interesting to hear that the lines are bugged. Though weird results - seem to get different exec lines based on a variable set at end of function, still gonna see if I can work out a pattern.

round idol Jun 8, 2020, 10:10 PM

#

@rugged violet Go to your pickup widget* -sry

rugged violet Jun 8, 2020, 10:10 PM

#

I will just start at the begnning and make it as simple as possible this as new to me

round idol Jun 8, 2020, 10:10 PM

#

right click empty space and type in "custom"

#

create a custom event

#

name it whatever you want - Pickup for instance

rugged violet Jun 8, 2020, 10:11 PM

#

ok done

round idol Jun 8, 2020, 10:11 PM

#

Go to your blueprint, do what @narrow kelp said, "get all widgets of class" ... etc

#

cast as he said, and get that pin which says "as XYZ_Widget" and type in the name of the event you just created

#

it will show up in the menu. click on it and connect the execution wire

rugged violet Jun 8, 2020, 10:13 PM

when the enemy attack me I want to ghost animation to keep looping

round idol Jun 8, 2020, 10:41 PM

#

@inland current you don't want that man, you want it to go up and down according to your HP. right? so it going up n down won't help

#

and forget animations, you can't do it like that, you need to script it and offset it in the viewport.

inland current Jun 8, 2020, 10:42 PM

#

I mean I want it to float @round idol

#

well I just the fade in and fade out already

round idol Jun 8, 2020, 10:44 PM

#

if you want it connected to your HP bar, you can't do it through animations like that

inland current Jun 8, 2020, 10:44 PM

#

so when the enemy attack me the health bar fade in but if I runaway from the enemy the health bar fade away

#

So these blueprint are a waste now

📎 unknown.png

round idol Jun 8, 2020, 10:45 PM

#

so you have the HP system setup already? Then I misunderstood. Just play the animation forward and backwards every time you get hit or something. Trigger events

#

So these blueprint are a waste now
@inland current well, idk what you wanted to achieve with that anyway so yea...sorry

inland current Jun 8, 2020, 10:48 PM

@round idol My whole idea is that I want the HP bar to float when the player is near a enemy when the player is not near a enemy then the HP fadeaway

#

I can only figure out how to for each loop every single text, where I want all names in one message

narrow kelp Jun 8, 2020, 10:58 PM

#

you can append a single long string or text

#

make a new string variable, and append each element in your for loop to that string

tame stream Jun 8, 2020, 11:00 PM

#

ooh so like save the appended string, and then use the appended string for additional players

#

makes sense

narrow kelp Jun 8, 2020, 11:01 PM

#

you wouldn't necessary want to save the string, because its harder to manipulate

#

but if you're getting ready to print something it can be useful

@inland current you need to "set percent" from 0 to 1 the bar, basically you need to get the Max life and Actual life and tranform in a number between 0 and 1. ex.: 0.4 = 40%

@tame stream first you create or load the save and save in a variable, than you can change the variable, after you change you need save it

@inland current looping?

@frozen dune give a example of what you want to do

inland current Jun 9, 2020, 1:00 AM

@thorn moth I just want it to keep looing when the enemy attacking

thorn moth Jun 9, 2020, 1:01 AM

you need to read the life variable inside the the Text widget function or make a event to update the life every time it change

inland current Jun 9, 2020, 1:01 AM

#

@thorn moth My whole idea is that I want the HP bar to float up and when the player is near a enemy when the player is not near a enemy then the HP fadeaway

frozen dune Jun 9, 2020, 1:02 AM

#

@frozen dune give a example of what you want to do
@thorn moth A store with 3 buttons (buy, sell, exit). Once buy is pressed, a list of equipments is shown to the player.

The list shows the available equipments, each with an image and status. The data comes from a spreadsheet. I made a base item widget to use along with ItemList and each individual item should create an instance of that widget.

thorn moth Jun 9, 2020, 1:02 AM

#

@inland current add a widget component to the enemy and inside add the life widget

#

than you will need to detect the distance of the enemy

inland current Jun 9, 2020, 1:04 AM

#

@thorn moth This is my enemy blueprint

thorn moth Jun 9, 2020, 1:04 AM

thorn moth Jun 9, 2020, 1:07 AM

#

items you can add to a datatable and than you read it inside your widget

inland current Jun 9, 2020, 1:07 AM

#

@thorn moth I did that, what next

thorn moth Jun 9, 2020, 1:08 AM

#

create a struct that has all information your items need, name, price, weight, wharever, than create a datatable. inside the datatable create just 2 items as example to read inside the your widget @frozen dune

#

@inland current ok, you can control the life widget inside the enemy or inside the widget, the easy way is to save the widget inside your component in a variable inside your enemy

inland current Jun 9, 2020, 1:10 AM

#

@thorn moth Oh that life bar that you see in the picture is the player life bar

thorn moth Jun 9, 2020, 1:10 AM

#

than when you enemy takes damage you can edit the life bar based on the enemy life, you need the Maximum Enemy Life bar and the Actual Enemy Life to calculate the percentage

#

add a "on any damage" to the graph

inland current Jun 9, 2020, 1:10 AM

#

Ok

thorn moth Jun 9, 2020, 1:11 AM

#

event tick you use very little

I'm managing to send the datatable data to the widget. It's showing the item widget itself in a list form that I'm not able to do it yet

I found a small tutorial on ListItem, but it's difficult to understand it properly.

@inland current you will use the "Event AnyDamage" in any game when dealing with life

@frozen dune than you get the items you want and create a button for each of those items with what items they represent

inland current Jun 9, 2020, 1:17 AM

#

@thorn moth made this myself but this the life bar that I'm trying to animate in the game

thorn moth Jun 9, 2020, 1:18 AM

#

@frozen dune I send just the name of the datatable row to the button, than it read the informations that need to create the button information

@inland current the animation is from the widget animation?

#

@frozen dune the best way is to create a widget that is just the button to buy the item
@thorn moth Is it possible to make them show like this:

Item1
Item2
Item3

And a scroll bar to whenever I have a lot more items ?

thorn moth Jun 9, 2020, 1:20 AM

#

yes, you add a vertical box and add the buttons inside the vertical box

#

I think the vertical box need to be inside a scroll box

inland current Jun 9, 2020, 1:20 AM

#

@thorn moth yea I know but I want to make sure that the animation works when the enemy come near the player

frozen dune Jun 9, 2020, 1:21 AM

#

that's the suggestion I was looking for =D
Never thought of using a scroll box
Thanks a lot @thorn moth . I'll try this

inland current Jun 9, 2020, 1:21 AM

#

also play a loop

thorn moth Jun 9, 2020, 1:21 AM

#

you can make the animation play in loop when the widget is created, in the event construct Play Animation in loop

@thorn moth when I'm near the enemy the life bar fade in but when I runaway from the enemy it fade out that works. But not the float animation

#

what did you use for the loop animation

thorn moth Jun 9, 2020, 1:25 AM

#

Num Loops to play = 0

#

@thorn moth So I don't use the Translation so just use Scale to animate the float animation right ?

thorn moth Jun 9, 2020, 1:30 AM

#

use the transform

#

no, the translation

#

is right

#

but you need to select the animation there in the red arrow

#

and connect to the play animation

inland current Jun 9, 2020, 1:32 AM

#

It work now but the animation is going to fast I just need to play slowly that's all

thorn moth Jun 9, 2020, 1:33 AM

#

yes, you can fix on the animation or change the playback speed in the play animation

inland current Jun 9, 2020, 1:33 AM

#

ok

#

but now i just need it to loop now

thorn moth Jun 9, 2020, 1:34 AM

#

Num Loops to play = 0

inland current Jun 9, 2020, 1:35 AM

#

@thorn moth do I do the loop in the event graph ?

thorn moth Jun 9, 2020, 1:35 AM

#

no just set the Num Loops to play = 0 in the Play Animation function

when it fade out the float animation doesn't keep going

thorn moth Jun 9, 2020, 1:39 AM

it can only play 1 animation each time

inland current Jun 9, 2020, 1:39 AM

this what I have now

thorn moth Jun 9, 2020, 1:39 AM

#

you can make the fade out animation float too

inland current Jun 9, 2020, 1:40 AM

#

oh ok I get it now so I had to do it on both side then wow silly me

#

so in this picture where do i go to slow down the animation if I may ask

thorn moth Jun 9, 2020, 1:41 AM

#

make the animation longer in this part

#

in the Play Animation you can change the "playback speed"

inland current Jun 9, 2020, 1:43 AM

#

I don't see play backspeed ?

@thorn moth can see a video what the Life Bar does now

thorn moth Jun 9, 2020, 1:50 AM

#

cool

inland current Jun 9, 2020, 1:50 AM

#

thanks

#

you see in the video it only plays in the beginning and at the end not in the middle

#

I guess I have to make it longer then

thorn moth Jun 9, 2020, 1:52 AM

#

in loop it should play all the time

#

are you executing the function with the looped animation?

#

you can start the loop animation when the start animation ends with "event animation finish"

inland current Jun 9, 2020, 1:54 AM

#

you can see in the video that it stop for minute then it plays again when it fadeaway

anyone have a source for height math?
I have cm, I want to display the height in feet and inches

thorn moth Jun 9, 2020, 2:00 AM

this is a question you can find easily on the internet

plush ridge Jun 9, 2020, 2:00 AM

#

have not been able to find anything online about this formatting

thorn moth Jun 9, 2020, 2:00 AM

#

just transform from cm to feet/inches before you show the number

inland current Jun 9, 2020, 2:00 AM

#

@thorn moth I did what you said and it doesn't play in the middle

plush ridge Jun 9, 2020, 2:00 AM

#

I have that, but it displays it with a decimal point, like 5.9 feet instead of displaying inches separately as an additive to show the difference between whole feet

#

I'm trying to use the x'x" format in the way we might display human height

thorn moth Jun 9, 2020, 2:02 AM

#

well, do you have a screenshot?

#

@inland current its the fade in animation that should be there?

I need some guidance : I opened the Roller template and like the concept of it, but I want to make the camera chase / behave like the Third Person template does. Is there a good way to change or set the blueprint so it follows the ball and orients the camera the way the ball is moving?

I.E get the camera to behave more like the third person chase camera instead of being fixed isometrically.

I dont know exactly how this template works, buy you can remove the fixed camera and add a camera to the ball

#

the ball need to be a pawn

and you can add it as a default pawn

You see in the video you can se that it's not working right

Why do floats become imprecise or just add random bits to the end? saving a float variable of 120.36 in the editor ends up turning it into 120.3600006

keen atlas Jun 9, 2020, 5:40 AM

#

Where is the second screen plugged into @somber igloo ?

#

Also, I highly discourage using == for floats due to the following:

#

@stuck hedge Floats (floating point numbers) store the most relevant part of a number with an offset of position, making it so it bleeds some precision in exchange of being able to store extremely large/small number.

My whole idea is that I want the life bar to float when the player is near a enemy when the player is not near a enemy then the life bar fadeaway

Sounds to me like your fade may be looping

@keen atlas I'm recording seconds for a racing game. I'm setting a default value as the best lap time value, and to test my function for converting a float to a readable MM:SS.SSS format, I entered a default value of 120.36 for the variable in the actor. However, after saving the actor it adds the extra bits to the number.

keen atlas Jun 9, 2020, 5:45 AM

@stuck hedge That's normal with floats, rounding errors are common. What I would say is to truncate the number before showing it on screen

I just want to fade in when near a then float then fade out when running away from then enemy
