wait is UT no longer maintained on github?

What's UT? Is that a Fortnite mode?

No? Then nobody's working on it

#

can someone please tell me why if I bought a template which is connected together why when I import them into unreal are they all broken into tiny meshes?

📎 1.JPG

#

thats how its suppose to look but unreal breaks them down into parts and not connected

cloud cobalt Sep 26, 2018, 3:16 PM

#

@iron wadi UT has never been a serious project at Epic

#

Fortnite and UE4 are their main business - one is short term, the other long term

#

UT was a goodwill gesture to the community, and the community wasn't large enough to keep development running when Epic pulled the 3 people working on it part-time

static viper Sep 26, 2018, 3:18 PM

ofc UT was!

#

any ideas why a mesh seemingly wont attach to a socket in levl editor? It 'attaches', but wont follow movement of the socket it's attached to

grim ore Sep 26, 2018, 4:49 PM

#

is the mesh being forced to another location on it's own? like some code in it's BP? are you sure it's attaching to the socket and not something else? are you sure the socket is on the mesh you are moving?

rich sparrow Sep 26, 2018, 4:50 PM

#

I just did a simple test with a sphere, that failed also. Was working some weeks ago

#

annoyingly I can see the socket moving when simulating also. Hmm will have to dig

dark depot Sep 26, 2018, 5:19 PM

#

are you sure your connecting it to the component that includes that socket and not the root of the object

ember hull Sep 26, 2018, 5:33 PM

#

Guys is there any side effect of moving projects, nativize from bp to c++, or is it better to rewrite it from scratch ?

#

im changing from bp to c++ because I heard its alot better in performance

grim ore Sep 26, 2018, 5:44 PM

#

if you need the performance go for it, if you are doing it because some stranger on the internet said something then.... well go for it 😃

#

now if you are doing it because you tested it and you need the performance gains that you tested and found then no, there is no real side effect other than having to rework your existing code.

#

is it true, that c++ is best for performance

smoky stream Sep 26, 2018, 5:51 PM

#

i would like to point out that for loops are not extremley common in most game logic

#

but yes, if you need it to be as fast as humanly possible, use C++

grim ore Sep 26, 2018, 5:51 PM

#

Will you be doing a math operation 1 million times in a row like the video shows?

God, every bp vs C++ benchmark is so fucking unrealistic

ember hull Sep 26, 2018, 5:53 PM

and thanks for the video, going to check

grim ore Sep 26, 2018, 5:53 PM

#

then the first part of that video is for you, if you are more comfortable about using C++ then use it.

ember hull Sep 26, 2018, 5:54 PM

#

im very new to both, I only want to choose, what is better for more potential and performance

polar hawk Sep 26, 2018, 5:54 PM

#

They aren't separate systems

smoky stream Sep 26, 2018, 5:54 PM

#

C++ is very tricky, but very rewarding to learn

#

so if you want to, go for it

grim ore Sep 26, 2018, 5:55 PM

#

nah, C++ is super easy. no more than 2-3 years of learning to get good at it

smoky stream Sep 26, 2018, 5:55 PM

haha yes™

screeches in concepts TS

#

and in modules TS

#

as well as reflection TS

supple totem Sep 26, 2018, 5:58 PM

#

where c++ gets tricky is that it lets you shoot off your own foot

#

wanna run a function from a pointer that you never once thought of pointing to anything

#

sure itl compile

#

then crash

#

yay

smoky stream Sep 26, 2018, 5:58 PM

#

with a segfault that you need valgrind to debug

#

or even better is getting a program that wont run if you remove a printf

supple totem Sep 26, 2018, 5:59 PM

#

never had that sounds fun

#

i will say visual studio's debugging is pretty nice

#

i am quite dumb but can use it to fix most things

worn granite Sep 26, 2018, 6:00 PM

#

@ember hull Actually performance is the lowest thing on my list of reasons to use C++

smoky stream Sep 26, 2018, 6:00 PM

#

not everything is exposed to blueprints

but you can use it through C++

you could just read the rules and guide...

solar sparrow Sep 26, 2018, 6:12 PM

I had quick flick through them but nothing to do with screenshots so I'm guessing it's fine.

astral rain Sep 26, 2018, 6:16 PM

#

I started with the intention of doing strictly c++ because every warned about BP performance. I would make simple mechanics in BP then redo it in c++ before removing the BP. But in my tests, aside from like two things, I'm not seeing a performance difference between the two.

smoky stream Sep 26, 2018, 6:17 PM

#

it depends on what you're doing

#

some stuff will be heavier in blueprints than other stuff

astral rain Sep 26, 2018, 6:17 PM

#

I mean, it's possible that performance gets worse the bigger the project (which will happen in most cases), but I'm not seeing huge red flags here.

#

Yeah, actor spawning is kinda harsh in BP.

#

And for loops running other for loops.

#

A for loop spawning 20+ actors is really rough in BP lol

smoky stream Sep 26, 2018, 6:20 PM

#

oof

surreal kite Sep 26, 2018, 6:34 PM

#

Oh geez Im spawning thousands of actors in for loops in a BP... is there a wiki or something on things you shouldnt do in BP and why?

smoky stream Sep 26, 2018, 6:34 PM

#

use the profiler

#

just find other ways to spawn blueprints

#

or pool them

surreal kite Sep 26, 2018, 6:35 PM

#

Im wondering if someone has already done this and wrote about it

smoky stream Sep 26, 2018, 6:35 PM

check epics youtube channel

they have a ton of optimisation stuff

surreal kite Sep 26, 2018, 6:35 PM

👍

sleek solar Sep 26, 2018, 6:36 PM

#

you shouldn't be spawning thousands of actors on the same tick at first place... even on C++

surreal kite Sep 26, 2018, 6:38 PM

Oh its delayed a second between iterations dont worry ;p

I guess I missed the point earlier heh

grim ore Sep 26, 2018, 7:11 PM

#

they are a thing if your an awesome person they want to show it around to. public tours I have not heard of 😦

#

before you build it's using the realtime, after you build it's using the lightmap settings. You might have to increase the resolution on the landscape or the light settings to fix that. Alternately if you are building in test and not production it might be low res.

strange eagle Sep 27, 2018, 1:20 AM

I created a new blueprint in the project and set it up the exact same way but its not affecting the project at all. i assumed theres some sort of step that I need to do to get it recognized by the project

livid haven Sep 27, 2018, 1:22 AM

#

You created a LiveLinkRemap asset and overrode that function?

strange eagle Sep 27, 2018, 1:22 AM

#

yeah it looks exactly the same in the picture

#

because the blendshapes need to have specific names like eyeBlinkLeft

#

but my blendshapes are called "Character_eyeBlinkLeft

livid haven Sep 27, 2018, 1:23 AM

I assume you have to actually tell something to use a given LiveLinkRemap asset somewhere.

#

Yup

same

livid haven Sep 27, 2018, 1:24 AM

No, you clearly know more, because you're trying to use this. I mean I don't know what any of this does or is or is for.

strange eagle Sep 27, 2018, 1:25 AM

#

i didnt even know what blueprints were until 1 week ago

livid haven Sep 27, 2018, 1:26 AM

#

So, somewhere, you're going to use the LiveLinkRemap blueprint you made by using a Live Link Pose anim node in an anim blueprint.

strange eagle Sep 27, 2018, 1:26 AM

#

i know where the anim blueprint is

#

so insert Live LInk Pose anim into the anim blueprint and connect it to the LiveLinkRemap?

#

ill check it out

#

thanks

livid haven Sep 27, 2018, 1:28 AM

#

Yeah, when you have the anim node selected, you see in the details panel that there's a property you can set to reference a LiveLinkRemap asset.

📎 unknown.png

#

in the MI viewer it works fine, i'm just having a heightmap point vertices towards the center of the mesh

#

however, in the level the vertices are being pushed in directions that I can't determine the source of

#

I've checked all the math in my materials / material functions and that doesn't appear to be the issue

likewise, the world position / rotation etc. of the mesh don't seem to have any bearing on the vertices going the wrong way

apparently my worldpositionoffset function doesn't work regardless of local rotation

Strange, you could try to force substepping

Check the project settings for that

Ok Ill give that a try. Does that reduce performance though?

Nope, stuff is still digging into the ground. I set the ground thickness to 1000 and now stuff doesnt fall out. Just digs into the ground then gets shot out

#

Wonder if its because they are low poly and "sharp"

cloud cobalt Sep 27, 2018, 1:04 PM

#

My guess would be, you simply have too many of them, and the limits of physics simulation can't resolve it

#

The falling blocks push the lower ones into the ground

surreal kite Sep 27, 2018, 1:14 PM

#

So thats a gif I copied from the internet. In my project Im seeing the same behavior with far fewer objects

#

I suspect it might be the sharp poly thing, I wasnt getting this with higher poly models

I think this was a problem I encountered too a long time a go using bullet physics

Hey guys, I am working on a fps game. I have attached a gun model to a socket on my guy’s arms, which creates a lot of wobbling and shaking while moving. Anyway to reduce the wobble?

grim ore Sep 27, 2018, 2:49 PM

#

Is the object you attached using physics? if not it should just move with the item in a 1-1 fashion if it's a socket

gleaming thicket Sep 27, 2018, 2:52 PM

#

It might not be. The gun was one whole object by itself (without specific parts unlike the human ehich has body parts)

grim ore Sep 27, 2018, 2:54 PM

#

well I can say taking the default character, adding a socket, and attaching a mesh to that socket I get a mesh that doesn't jitter. my only thoughts are the mesh you are attaching is simulating physics so it's bouncing due to that or it's possible it's colliding with the mesh it is attached to

Can someone tell me how much truth is in this snippet from an article I'm reading PlayerController The most important part of PlayerController is that it can get input from Player (keyboard, mouse, touch, pad etc) it can posses Pawn and Character. You can have different PlayerControllers if you have different movement functionalities. For example if you are controlling a car with CarPlayerController you should have different PlayerController for controlling an air plain.

worn granite Sep 27, 2018, 8:01 PM

#

everything before for example is mostly fine.

#

You can have different player controllers for any particular reason

quasi star Sep 27, 2018, 8:01 PM

#

I was thinking the same thing

#

But you would put driving and flying controls on the car and plane pawn, instead of two controllers right?

worn granite Sep 27, 2018, 8:02 PM

#

You can have global inputs in the controller, things like pause and stuff.

regal mulch Sep 27, 2018, 8:02 PM

#

That's not correct

#

You have Different Pawns and Characters

quasi star Sep 27, 2018, 8:02 PM

#

especially if you could leave a car walk to a plane and get in a fly?

regal mulch Sep 27, 2018, 8:02 PM

#

You are most likely gonna have the same PlayerController

worn granite Sep 27, 2018, 8:02 PM

#

And then you can have the specific controls on the characters

regal mulch Sep 27, 2018, 8:02 PM

#

As you can't change the PC without swapping level and the whole GameMode out runtime

#

Pawn/Character depending Input and Movement goes into the Pawn

quasi star Sep 27, 2018, 8:03 PM

Yup, awesome. I didn't feel right after reading that so it's good to get that cleared up.

regal mulch Sep 27, 2018, 8:04 PM

#

Your PC can have the logic to possess the Pawns

#

E.g. swap between Character and Car

#

And keep track of that state

#

But that's it

#

Imagine having 20 different things to control, you'd have one huge PC :D

maiden swift Sep 27, 2018, 8:05 PM

#

That makes sense for games with many different pawns that do different things.

regal mulch Sep 27, 2018, 8:05 PM

#

Yeah, but just for having thigns clean you would also want to put pawn input into the pawn

#

Even if it's only one pawn

worn granite Sep 27, 2018, 8:05 PM

#

if you get super into it, you can also bind inputs to the inputcomponent manually so that you have special input "modes" in a pawn. So you might only bind the look and ADS controls if you don't want the player to be able to start firing. That's a pretty neat approach, but it doesn't actually impact what functions go where.

regal mulch Sep 27, 2018, 8:05 PM

#

It doesn't hurt putting it into the PC if it's only one Pawn of course

#

But well

worn granite Sep 27, 2018, 8:06 PM

#

That also requires C++

regal mulch Sep 27, 2018, 8:06 PM

#

You can't swap the PC like the article above makes believe

maiden swift Sep 27, 2018, 8:06 PM

#

Yeah you could certainly do it that way.

dark depot Sep 27, 2018, 8:06 PM

#

just makes it nicer to have things that are common in the PC and the pawn have pawn specific things

maiden swift Sep 27, 2018, 8:07 PM

#

I honestly have never done that. Didn't think of it from that perspective.

#

I'm used to keeping input in the PC.

quasi star Sep 27, 2018, 8:07 PM

#

Yup I agree, but what about AI. Would you have a PilotAIController, DriverAIController and a PedestrianAIController?

maiden swift Sep 27, 2018, 8:07 PM

#

Then again I tend to work on relatively simple games.

#

These days my pawns tend to have very little going on in the event graph and just contain functions to be called externally.

it all depends on the person making it for the most part it can go wherever

rustic panther Sep 27, 2018, 8:08 PM

is there an article or somethign that explains why Unreal adds tiny values to world objects when you rotate them/move them like a 34 Z rotation will turn into 33.99999 or 34.00001

dark depot Sep 27, 2018, 8:08 PM

#

floating point precision

rustic panther Sep 27, 2018, 8:09 PM

#

ya but it changes the value when you enter it

quasi star Sep 27, 2018, 8:10 PM

#

floating point arithmetic is strange, ever tried 0.1 + 0.2 != 0.3 ?

rustic panther Sep 27, 2018, 8:10 PM

#

so it changes it so the math is easier?

quasi star Sep 27, 2018, 8:11 PM

#

@rustic panther If you enter 34 in the ui then I guess it's a bit odd that it does give you 33.999999 usually you get those rounding issues after applying calculations.

rustic panther Sep 27, 2018, 8:12 PM

#

I'm not trying it atm, it's just something I thought about and wanted ot know... I'm fairly certain that happens though

#

it does it most on rotations, enter a whole number, click off then back on it

#

it probably will change the value slightly

quasi star Sep 27, 2018, 8:13 PM

#

Seems ok here, unless i drag when clicking back on the input, which i guess the inc/dec step on those inputs are just set to small numbers for finer control maybe?

#

Can I ask what sort of data or functions people usually put on game instances? Is this used for higher level stuff such as save/load game, error handling etc..

I'm instantiating a widget blueprint from a different class blueprint. The widget has a heiarchy: Widget > Canvas Panel > Canvas Panel > Background Image, Text Box. I'm saving the instance as a User Widget variable in the class blueprint. How do I access/modify the different levels of the hierarchy through the blueprint?

#

Or as a more general question, how to I access a class's instance variables via blueprints?

grim ore Sep 27, 2018, 10:54 PM

#

you can get child or get parent and then slot them as the container or the type. If it's a variable you exposed you just get that variable (easiest way)

plush yew Sep 27, 2018, 10:56 PM

#

Im seeing options lik e"Get Child At", "Get Child Index", and "Get Children Count"

#

are any of those what you're refering to?

#

Thanks for the help, btw

grim ore Sep 27, 2018, 10:57 PM

#

that would be the generic way yes, like if you were at the top canvas panel and wanted the background image you could use the get child to get down to that level

#

if you exposed the variables for what you want, say the background image, you could just get that directly

plush yew Sep 27, 2018, 10:58 PM

#

so at the lowest lever there is both the background Image and Text box

#

can I call them by name?

grim ore Sep 27, 2018, 10:58 PM

#

so like you create your widget, save the instance variable, then later you can get that instance variable -> get background image variable

#

turn them into variables, its an option in the top right of the editor when you are designing the widget

#

then in the graph editor view on the left is the list of all variables in that widget, click the eyeball icon next to the name to expose it

#

just make sure to save/compile when done

plush yew Sep 27, 2018, 10:59 PM

#

Okay, I have that set

#

I had them as variables so that I could edit them through the scene details

grim ore Sep 27, 2018, 10:59 PM

#

you should be able to just drag off your variable you saved after you created the widget now and get variable name

plush yew Sep 27, 2018, 11:00 PM

#

I can do that, but I was hoping to modify them from the other blueprint that instantiates the widget

grim ore Sep 27, 2018, 11:00 PM

#

yes doing what I said above

#

so your other BP creates the widget, after that you save it right?

plush yew Sep 27, 2018, 11:01 PM

#

yup

#

ahh, I see

when I drag a wire from it and type get

#

it autofills with variables

plush yew Sep 27, 2018, 11:02 PM

#

I was just right clicking and looking for a method box that would let me, idk, like search for a generic object type or something

#

in general, is that how class instance variables are accessed?

grim ore Sep 27, 2018, 11:02 PM

#

ah gotcha, nah the node searchy thingy is context sensitive

plush yew Sep 27, 2018, 11:02 PM

you drag a wire from that class in the blueprint

#

?

grim ore Sep 27, 2018, 11:03 PM

#

so yes

plush yew Sep 27, 2018, 11:03 PM

#

I see, that makes sens

#

*sense

grim ore Sep 27, 2018, 11:03 PM

#

yeah if you drag off an int for example you would get things you can do with an int

#

same with a generic object or say a specific class of widget

plush yew Sep 27, 2018, 11:03 PM

#

awesome. makes perfect sense

if you are using baked lighting you can use "Turn on the "Use Emissive for Static Lighting" parameter" on the items to allow lightmass to light using that. If you want something special tho like realtime emissive lighting that's going to be different

winged crypt Sep 28, 2018, 12:28 AM

Does UE support static shadows for foliage? Shadowless foliage looks like crap

viscid canyon Sep 28, 2018, 12:34 AM

#

@boreal night I don't see why you couldn't have something within the level bp that you could reference the temperaments of each group for each group.

#

I personally don't see why it would HAVE to be done in C++

#

or even have it in that particular pawn where when that actor sees another actor after casting to, then checks its properties to see if they are friendly or not

#

So you could On See Actor and after casting to that class, you could then check some value to see if you are friendly with that particular actor or not. Then branch based on that.

#

Unless I am completely off base here? anyone? lol

icy bone Sep 28, 2018, 12:40 AM

#

@boreal night BP is basically exposed C++ with UE4 macros. I believe u can use BP for ur case but dunno exactly what u need so...

viscid canyon Sep 28, 2018, 12:41 AM

#

@icy bone So from what i can understand is that he has pawns in his level that need to, when they see another pawn, check their temperament towards that pawn and react accordingly

#

So basically a bit of AI to determine how they act..

boreal night Sep 28, 2018, 12:42 AM

#

@viscid canyon how could I reference a temparaments?

#

so after set member to team ID, what I do>

#

?

#

You wrote: "So you could On See Actor and after casting to that class, you could then check some value to see if you are friendly with that particular actor or not. Then branch based on that."

#

I will try this first

viscid canyon Sep 28, 2018, 12:45 AM

#

So do you want to basically set it up to where a TEAM has an opinion of another TEAM's members?

#

or is at an individual level? Meaning... say... I have a Joe Guy who is part of team PIRATES and John Doe who is of team NINJAS and you want joe, when he sees john, to see if he is a pirate?

boreal night Sep 28, 2018, 12:47 AM

#

No just to identify another pawn as enemies or neutral or friend

#

maybe I was offset when using set member team ID

worn granite Sep 28, 2018, 12:47 AM

#

Also while I can see how you might want to define faction attitudes per-level, the level BP would not be the correct place for it. I'd use WorldSettings for that - I think you can specify a custom world settings class for UE4 to use.

I really new at this thing

I guess I don't know what you mean by AI Perception

#

hah

I don't think Epic even works on the AI systems anymore 😩

boreal night Sep 28, 2018, 12:51 AM

#

Let say, in my game there is a defense tower, when a pawn go near it, the tower will check first if he is friend or enemy or neutral

worn granite Sep 28, 2018, 12:51 AM

#

that particular field is not editor exposed, but the type itself is editor-friendly

boreal night Sep 28, 2018, 12:51 AM

#

then if he is enemy, will shoot

viscid canyon Sep 28, 2018, 12:51 AM

#

So Mario, would you say that the tower and the pawn passing it are of different TEAMS?

boreal night Sep 28, 2018, 12:51 AM

#

but all pawns seemed to set as neutrals

#

yes, different team

viscid canyon Sep 28, 2018, 12:52 AM

#

I don't see why you couldn't check a exposed param on that pawn.

boreal night Sep 28, 2018, 12:52 AM

#

and whats is that?

#

exposed param

#

how to do it?

#

give him a boolean variable?

viscid canyon Sep 28, 2018, 12:53 AM

#

you could even give it a string variable and compare

#

or an int... that would work too. Team 1,2,3,4

boreal night Sep 28, 2018, 12:53 AM

#

I think I'm getting close

viscid canyon Sep 28, 2018, 12:54 AM

#

when you see that actor, check to see if they aren't part of your team, then fire

boreal night Sep 28, 2018, 12:54 AM

#

It's good thing I ask here

#

right, I will try it

dim arch Sep 28, 2018, 12:54 AM

#

add cylinder collision to the tower, on overlap get actor team ID

boreal night Sep 28, 2018, 12:54 AM

#

before, I was like hitting a wall there

grim ore Sep 28, 2018, 12:55 AM

#

If you just want to define something in terms of Neutral, Friendly, Enemy for your types look into an enum so you can actually use those terms instead of 0,1,2,etc.. If you want to assign actual different values like team # 1, 2, 3, etc.. then an int is good nuff

boreal night Sep 28, 2018, 12:56 AM

#

Thank you

sonic pagoda Sep 28, 2018, 1:03 AM

#

ive got another crazy bug

#

in editor, i have these procedurally generated tunnels that have proper collision and all

#

in a build

#

they have no collision at all

#

what could possibly be that different from PIE and a build to cause different collision settings

light thunder Sep 28, 2018, 1:16 AM

#

@sonic pagoda Try making a regular tunnel, using the same settings as your procedural tunnels but one that is just static, see if it still has collision

golden tide Sep 28, 2018, 1:17 AM

#

What's the recommended Cubemap Size in UE4?

viscid canyon Sep 28, 2018, 1:18 AM

#

@grim ore ah yes. Forgot about using enum. That might make sense as you could then test if it equals Teams.Blue or Teams.Red

sonic pagoda Sep 28, 2018, 1:38 AM

#

@light thunder good idea, im going to try that, as well as checking if the individual static meshes show collision in a build version

#

yup, thats great, now i can pinpoint that the bug is somewhere in the actor that regenerates the tunnel on runtime... so at least i know its not the actual static mesh or the tunnel itself

#

thanks

icy bone Sep 28, 2018, 1:51 AM

#

@boreal night U may wanna look into AI Perception Component. And regarding teams there are many ways to do it but like mentioned an exposed variable could do fine

#

Reason to use Perception Component is that it does the query for u, so u dont need to check for range overlap events urself etc...

#

It also deals with visibility, so u dont need to do ur own raycasts

boreal night Sep 28, 2018, 1:55 AM

#

Thank you, I'm really new at this, I already set the aiperception with sight config. But how to do exposed variable?

icy bone Sep 28, 2018, 1:55 AM

#

each variable has an Eye icon next to them

#

if u click it so the eye is open

#

then other bp can access

boreal night Sep 28, 2018, 1:56 AM

#

the other BP access it by on perception update?

icy bone Sep 28, 2018, 1:56 AM

#

no

#

all BP that u wanna have this detection u need to add perception component to

#

then u setup the perception events

#

to fire when it detects an actor

#

then convert that actor to ur actor type that has exposed team variable

#

then get that variable and check

sonic pagoda Sep 28, 2018, 2:00 AM

apprently i have an engine bug

@sonic pagoda U can generate ur own mesh as mentioned by some, hard work :/

sonic pagoda Sep 28, 2018, 2:07 AM

not hard work... art work lol

icy bone Sep 28, 2018, 2:09 AM

@sonic pagoda lol

sonic pagoda Sep 28, 2018, 2:10 AM

#

but yea in my case hard work, as a terrible artist lol, whatever, ill figure it out

icy bone Sep 28, 2018, 2:11 AM

#

if its always tubes then a workaround is to make many tube sections

#

and connect them procedurally

#

since each section will be a model they will have proper collision

sonic pagoda Sep 28, 2018, 2:12 AM

#

yea thats true, its really not that hard

icy bone Sep 28, 2018, 2:13 AM

#

only good thing with spline is the infinite number of possible curves and bends etc, but with enough sections should be fine

boreal night Sep 28, 2018, 2:14 AM

#

or do I?

icy bone Sep 28, 2018, 2:14 AM

#

@boreal night ok ure a bit off track

#

u wanna use the last sensed stimuli

#

and u can config that number in the component to higher number

#

but u need first to ask urself if i.e ur tower should keep shooting at its initial target or new target, or should there be some kind of aggro level

#

lets say there are 10 enemies in range, who to shoot

boreal night Sep 28, 2018, 2:19 AM

#

For now, I have only 1 Intruder, but yes, I need to look into the target choosing later

sonic pagoda Sep 28, 2018, 2:19 AM

#

the problem is generating collision at runtime, but if i can make it happen during the construction script, somehow run that before runtime, then i wont have an issue...

#

the whole issue is that i destroy the spline on begin play, and recreate it for "procedural generation" but if i can make the entire thing generate on level load on its own construction script than collision will be there.. but thats another issue, forcing construction script to change

icy bone Sep 28, 2018, 2:21 AM

#

@boreal night i think ur code might qork

#

work

#

the Target node from the Info

#

is that an actor?

#

then u can cast directly

i think you need to do some studying, from what i read you seem to have a lot of misconceptions

about bp

try to follow a tutorial, like the unreal engine twin stick shooter tutorial

with enemies

Udemy, yes, I am considering it

sonic pagoda Sep 28, 2018, 2:26 AM

so you are using the ai perception component in a character class?

#

its pretty straight forward, it has events like on seen, on heard

#

or you are using it in an ai?

boreal night Sep 28, 2018, 2:27 AM

yes, in my Tower pawn class

You have several lights in your level and you want them all to turn on or off when an event occurs.

I think nativization gets way more interest than it should

#

If you have game thread performance issues, move offenders to C++

#

It's unlikely you have that much code to write, and the API is often pretty consistent

@plush yew most people say you just have extra bones or it's not named properly. Look for loose bones not part of the main hierarchy and try to name your root the same as what UE4 expects. Alternately like they said import it into blender and export it out of blender.

plush yew Sep 28, 2018, 2:36 PM

#

We can try to do the first part, but it would be strange, because we didn't change something in the bones we just took the standard rig from MAYA/Mixamo

#

Also importing it to blender gives this result:

if it's not coming into blender like you expect it seems like it might have a problem 😦

You might have to find better help in #animation but I think this is less of a UE4 issue and more of a source issue.

Myself, I'm very happy with Blender - decade long user. Like all software, it's great at some stuff, less so at other stuff. The good part for me is that Blender is free, and extremely versatile - we use it for trailers, for example, because it just happens to have a full video editor embedded

Blender definitely has a fairly aggressive interface for new users, it's always been an issue, and it's very slowly getting better. Not the kind of software you can use with no reference.

Hi guys, I am doing a OOP class, and am familiar with some OOP design but I come from a data science background.

What do you call something that will push actors away from it by constantly applying a force? Physics thruster only works on meshes its attached to right? I want one where it stays in one spot and pushes things that get near it

I tried force field but that seems to only be giving me results for a sphere that just blocks you from going into an area

Trying to figure out how to lerp a widget between two positions

#

I found the set position in viewpoint box thing, and the lerp box thing

#

in the event grapnh

#

andI found a 'get defualt window position' which sounded promising, so I wanted to be able to take the default position shown in the viewport and save that as the final position

#

is says that the return value of that is of variable type 'int point structure'

#

but set poisitionin viewport takes a vector 2d

#

can't seem to find a way to cast the int point structure to a vector 2d, so it seems like maybe 'get defualt window position' is not the right function

#

anyone have any ideas on how to get the default position (the one saved in the viewport) and save it as a vector 2d

#

?

grim ore Sep 28, 2018, 9:19 PM

#

ok so for moving UMG stuff you have 2 options. doing it in code or doing it with the animation system in the editor.

#

for doing it in code you have to know a few things and the main one is the container or parent controls the child and it's options for positioning.

#

the biggest one is the canvas panel is the only real one that allows exact position, the rest use fills and alignments

#

so first thing first, is the widget you want to lerp in a canvas panel?

plush yew Sep 28, 2018, 9:21 PM

#

It is!

#

and thanks again, you helped me out with something yesterday

#

I just found how to get the target's render transform

#

so from that can I cast to it's local position or something?

#

I'm pretty sure I have the parent transform set to match with the screen space

#

so I wonder if I can just get it's local position and lerp that around?

#

*its

grim ore Sep 28, 2018, 9:22 PM

#

the key is the parent controls the widgets transform settings

#

in terms of position, alignment, etc.

#

so you would get your widget that you want to move -> use the "Slot as Canvas Panel" node to get the parent slot -> use the set XXX node for alignment or position or whatever you want to set

plush yew Sep 28, 2018, 9:24 PM

#

I'm just seeing 'slot as canvas slot'

grim ore Sep 28, 2018, 9:24 PM

#

and yes the position is pretty much always considered "local" as it's the position in the parent

#

yeah canvas slot

#

I never quite get the nodes right from memory lol

plush yew Sep 28, 2018, 9:24 PM

#

you're good, haha

#

so is slot then the term that refers to a widget's position?

#

and slot as canvas slot would mean the widget's position as relative to the paren't canvas's slot?

haven't heard the word slot used before in this context

grim ore Sep 28, 2018, 9:26 PM

#

well the slot as nodes are just shortcut nodes they added in that are basically "get Parent -> Cast to XXX" in one node

plush yew Sep 28, 2018, 9:26 PM

#

ah, I got you

#

so it's just retreiving the parent canvas and outputting that

grim ore Sep 28, 2018, 9:27 PM

#

yep. If you look at a widget in the designer in the details panel you will see the first thing is the "Slot (whatever) section

#

and you will notice all of the unique settings for that slot type for setting how it behaves

#

like the canvas being the only one with defined positions, things like that

plush yew Sep 28, 2018, 9:28 PM

#

hmm, okay

#

so I followed a toutorial online, which I had me nest the text box so it goes canvas > canvas > text boxes /background

#

I'm pretty sure the top one in the heirarcy maps to the screen size, and it's the lower canvas that I want to manipulate the location of

#

do you know which one slot will grab?

grim ore Sep 28, 2018, 9:30 PM

#

so the 2nd canvas acts like a "window" with stuff in it basically?

#

and you want to move that

plush yew Sep 28, 2018, 9:30 PM

#

yeah

#

exactly

grim ore Sep 28, 2018, 9:30 PM

#

make that 2nd canvas a variable and expose it so you can change it

plush yew Sep 28, 2018, 9:30 PM

#

they're all saved within one blueprint

#

ah

#

that makes sense

grim ore Sep 28, 2018, 9:30 PM

#

then you would get that canvas panel thru the variable, slot as canvas slot, set position, profit

#

the key with widgets is the parent owns them for how they are displayed, its super confusing until you understand that

#

its why people dont understand why they cant move something in a vertical box or a border

plush yew Sep 28, 2018, 9:31 PM

#

so then do I need to still slot it?

#

since I can now just grab the canvas by name?

grim ore Sep 28, 2018, 9:31 PM

#

yep the act of going "slot as " is what gives you a refernce to the parent and then you get the position stuff

#

I could be wrong but let me verify lol, its been a bit

#

yep nope I was right, you have to slot it

plush yew Sep 28, 2018, 9:32 PM

#

so if the top canvas has the position for the canvas I actually want to move, why not set the top canvas to a variable and grab that directly?

grim ore Sep 28, 2018, 9:32 PM

#

Its weird but the variable is the widget or object reference while the slot as XXX is the slot itself which controls the layout

plush yew Sep 28, 2018, 9:33 PM

#

am I grabbing more than just the canvas when I set it as a variable?

#

I see, so the canvas is just a component of the 'object' in the hierarchy?

grim ore Sep 28, 2018, 9:33 PM

#

so like when you save a reference to a widget, like a button or the canvas slot, it's just that object itself

#

above that or another part of it is the slot is is occupying which you have to get at by doing the slot as XXX node

#

its really weird I know lol

plush yew Sep 28, 2018, 9:34 PM

#

oh, so when I save it as a variable it's just looking at it as a generic object

#

and I have to specify what components it has that I want using slot

grim ore Sep 28, 2018, 9:35 PM

#

well its specific as in a button or a image or a canvas panel object

plush yew Sep 28, 2018, 9:35 PM

#

is that accurate?

grim ore Sep 28, 2018, 9:35 PM

#

the key is that each object in the hierachy occupies a slot and that slot is the parent basically

plush yew Sep 28, 2018, 9:36 PM

#

the slot is the parent, or the slot is owned by the parent?

grim ore Sep 28, 2018, 9:36 PM

#

and the only way to adjust how the object behaves in terms of position and such is by talking to the parent slot not the parent object....

#

I guess more the 2nd?

#

if you grab your canvas panel you want in your graph, and drag off it you wont find "Set Position" but if you drag off the canvas panel, slot as canvas slot (assuming the parent is that which you said it was), then drag off that you will find "Set Position"

plush yew Sep 28, 2018, 9:37 PM

#

okay. So you're saying that the top canvas owns a slot which the canvas that I want to manipulate occupies, so I have to get that slot, rather than the object I want to manipulate. That makes sense.

grim ore Sep 28, 2018, 9:37 PM

#

but if you were to go right for that top Canvas Panel you would not get access to the set position node as it's an object and not a slot...
