#

my unreal engine repo got bigger in size in 20 commits than the perforce one in 500

safe rose Oct 28, 2017, 8:58 PM

#

It's like Perforce and Git had a love child

gentle ivy Oct 28, 2017, 8:58 PM

#

ah maybe it's bigger on the server

frank escarp Oct 28, 2017, 8:58 PM

#

and by commit 20 i had a 50 gb .git folder

gentle ivy Oct 28, 2017, 8:58 PM

#

but I use github

frank escarp Oct 28, 2017, 8:58 PM

#

50 gb

gentle ivy Oct 28, 2017, 8:58 PM

#

so it's easy

frank escarp Oct 28, 2017, 8:58 PM

#

on the local .git

gentle ivy Oct 28, 2017, 8:58 PM

#

oh

#

let me check that

#

6 gb

#

not bad

frank escarp Oct 28, 2017, 8:59 PM

#

DWVR project size is around 8 gb

gentle ivy Oct 28, 2017, 8:59 PM

#

my .vs is 5gb

frank escarp Oct 28, 2017, 8:59 PM

#

but git LFS does not do deltas

gentle ivy Oct 28, 2017, 8:59 PM

#

nah you upload all the file each time

#

I believe thats the same with perforce binary files as well

frank escarp Oct 28, 2017, 8:59 PM

#

so a resave on a unreal map (no changes, but maybe timestamp) will make the whole thing save again

#

oh its not (at least on the server)

#

it compresses/deltas it

gentle ivy Oct 28, 2017, 8:59 PM

#

ah

frank escarp Oct 28, 2017, 8:59 PM

#

you do send the full file to the server

gentle ivy Oct 28, 2017, 8:59 PM

#

yeah perforce will delta it

#

on the server just not the transfer

#

so you transfer the map over

frank escarp Oct 28, 2017, 9:00 PM

#

wich is ok

gentle ivy Oct 28, 2017, 9:00 PM

#

its better than git lfs sure

#

but the big thing I've loved with LFS is that I no longer need to mess around to compile

#

you know how perforce you have unset readonly in bins for plugins and engine and project and etc

tall pendant Oct 28, 2017, 9:00 PM

#

can you run plastic scm locally? @safe rose

gentle ivy Oct 28, 2017, 9:01 PM

#

for some reason git sets to read only but not the bins because they aren't lockable

#

soooo your work routine changes completely from messing with the file system to just start working

#

@tall pendant do you mean self-host

#

cause you can self host it

tall pendant Oct 28, 2017, 9:01 PM

#

yes

gentle ivy Oct 28, 2017, 9:02 PM

#

yes

tall pendant Oct 28, 2017, 9:02 PM

#

thats nice!

gentle ivy Oct 28, 2017, 9:02 PM

#

and the guy who makes the UE4 plugin for it also makes the git lfs plugin

brave gate Oct 28, 2017, 9:02 PM

#

you know how perforce you have unset readonly in bins - like for default for any new file? no

#

but you know how to do it manually, right? 😃

gentle ivy Oct 28, 2017, 9:02 PM

#

right

#

but you don't have to do that in git cause its not lockable

#

in fact perforce as a setting for that

#

but its global not for dlls only

#

so you can either set all your files as readonly or none on perforce push

#

where git is MUCH easier and flexible

#

the only REAL issue with git lfs is that when you push it doesn't unlock the files.

brave gate Oct 28, 2017, 9:04 PM

#

actually, there's some server setting - like "make every file of this writeable"
seen on Unreal docs somewhere

#

didn't work for me

#

but maybe I did something wrong

#

wait a sec

gentle ivy Oct 28, 2017, 9:04 PM

#

yes that is what I was talking about

#

its in your workstation setting

#

its global for all files not just dlls

#

which you don't want DLLs to be readonly EVER but you do want things like uassets

#

So its a fun balancing act of all these options that really don't do exactly what you want

brave gate Oct 28, 2017, 9:05 PM

#

they say it doesnt have to be global

#

check this

#

https://docs.unrealengine.com/latest/INT/Engine/Basics/SourceControl/Perforce/

How to setup Perforce so that you can share assets with other on your team.

#

P4 Typemap

#

let us know if you could make it work, I failed, I don't know why 😉

gentle ivy Oct 28, 2017, 9:07 PM

#

so the types are different that's how to actually handle and diff the file

#

like a binary type checksums where a text type unify diffs

#

I am not sure if it effects readonly or not

#

"Setting the typemap will affect how files get set to read only or writable inside of Perforce"

#

hmmm

#

so according to the screenshot in the docs you linked and https://www.perforce.com/perforce/r14.2/manuals/cmdref/file.types.html +w means always writable which means shouldn't be readonly

#

but by default dlls are +w?

#

but my typemap is empty

brave gate Oct 28, 2017, 9:13 PM

#

it doesn't look like default is +w, suspicious

gentle ivy Oct 28, 2017, 9:17 PM

#

yeah it seems like this will solve that

#

😄

brave gate Oct 28, 2017, 9:41 PM

#

glad to hear that, sir! 😃

light thunder Oct 28, 2017, 11:04 PM

I'm trying to understand level streaming better -- is the persistant level always VISIBLE or just always LOADED....meaning, does a huge persistant level with a lot of draw calls affect performance if you are in other sublevels, or does it just take up memory?

maiden swift Oct 29, 2017, 12:04 AM

#

@light thunder The persistent level is always loaded, so being in a sublevel doesn't unload anything in the persistent level.

#

As far as I know, you cannot change the visibility of a persistent level at runtime; only in the editor.

marble lynx Oct 29, 2017, 12:48 AM

#

@light thunder @maiden swift a persistent level is just that, persistent (always there). You can't unload it, because that's what the game world is running on. All dynamically spawned items exist in the persistent world

mint raptor Oct 29, 2017, 12:57 AM

#

Is there aa way to get the center location of an object?

#

In world coordinates

south ridge Oct 29, 2017, 1:11 AM

#

Doing a large persistent level with lots of drawcalls IS bad

#

In our game, we have a multitude of persistent levels loaded in the same world, plus even more levels with actual graphics content

#

The persistent levels only store non-visual stuff (and, of course, they store state of players and other things that exist in the entire world)

#

There is one root persistent level used as the startup map, then it loads all neccessary additional persistent levels manually. The root level is the only 'true' persistent level in that sense, everything else is automatically streamed

#

The reason is that we have several intersecting 'worlds', not all of them have to be loaded and functioning (but you can still see other world from current world etc)

#

You can make persistent levels unloadable if you do a similar thing - keep one root and multiple persistent levels

light thunder Oct 29, 2017, 1:32 AM

#

@marble lynx WHY is this happening then?

📎 2017-10-28_1922.png

blissful kettle Oct 29, 2017, 1:46 AM

#

So I had downloaded git lfs because of large assets to connect to github. I've reached my limit for the storage. Any one have some advice?

light thunder Oct 29, 2017, 1:47 AM

#

Welp, I think I figured out the main issue on my simulator....tossed down a pawn and fly up and look down...practically NOTHING IS BEING CULLED!!! How do I fix this besides putting a cull distance on every single object? Is there a best practice in terms of laying down cull volumes?

📎 2017-10-28_2145.png

south ridge Oct 29, 2017, 2:02 AM

#

Also seems like there's not enough LODs

marble lynx Oct 29, 2017, 2:05 AM

#

@light thunder Your level isn't being automatically loaded, by default they're usually not loaded. So you need to load it.

#

You can do it either VIA blueprints, or set it to Always Loaded

#

Inside your Levels Panel, I believe you just need to right click the level and change Streaming Method to Always Loaded

light thunder Oct 29, 2017, 2:11 AM

#

@south ridge the nature of the game is teleport based, there will be no locomotion so I really just need a good way to cull that stuff

hardy socket Oct 29, 2017, 2:18 AM

Hello - I am wondering, has anyone here delt with the problem of Unreal not compiling a .dll file?

#

LogStaticLightingSystem: Warning: WorldSettings.bForceNoPrecomputedLighting is true, Skipping Lighting Build! WHY WOULD THIS EVER BE??!

hardy socket Oct 29, 2017, 2:22 AM

#

It is to the point where every time I try and make an unreal project, the same error pops up everytime so I never actually get into unreal itself as trying to recompile via visual basic doesn't seem to work

grim ore Oct 29, 2017, 2:23 AM

#

@light thunder that is an option in the world settings, you would set it if you don't want lightmaps

light thunder Oct 29, 2017, 2:23 AM

#

@marble lynx I've done something wrong...I changed it to always loaded but now this? All lighting is in the persistant map and the level change only loads a sublevel and it goes dark

📎 2017-10-28_2222.png

#

@grim ore I get it and it makes sense if you were doing a bunch of dynamic lights but whyyyyyy would that default

grim ore Oct 29, 2017, 2:24 AM

#

it doesnt default as far as I know

light thunder Oct 29, 2017, 2:24 AM

#

Must invent timemachine to kill past Blake for randomly clicking things

marble lynx Oct 29, 2017, 2:27 AM

#

well if your skipping the lighting build your sublevels aren't going to have lights

grim ore Oct 29, 2017, 2:29 AM

#

That error message will pop up if you disable static lighting completely in your options as well

toxic wagon Oct 29, 2017, 2:31 AM

#

I'm trying to make a blinnphong material :v

light thunder Oct 29, 2017, 2:34 AM

#

@marble lynx I watched it, it built the lighting for all 2levels

#

but the first sublevel is dark

marble lynx Oct 29, 2017, 2:43 AM

#

Change your sky light (or add one) to dynamic (Moveable) and try again real quick, if it's dark it's a lighting issue

light thunder Oct 29, 2017, 2:49 AM

#

I'm not supposed to mess with any of those options at all right?

📎 2017-10-28_2249.png

#

I tried that....it's still dark

#

Just making sure, Level Streaming Volumes are only used to trigger a load/unload, they don't do much else correct? I don't have any volumes because the level load is a widget/keypress event

marble lynx Oct 29, 2017, 2:50 AM

#

Scenario1?

#

Scenario1 is still being loaded by Blueprints

#

so it sounds like you're not loading Scenario1

light thunder Oct 29, 2017, 2:51 AM

#

I'm hitting a key that loads it

#

the problem is the lights that are on persistant map aren't showing

marble lynx Oct 29, 2017, 2:52 AM

#

Do they show if you set the map to Always Loaded?

light thunder Oct 29, 2017, 2:52 AM

#

well, if I load that map it's there by default but when I hit the key I have bound to activate the level load, it all goes dark

#

goddamnit

#

I feel like I am about to learn something very important and very basic

📎 2017-10-28_2254.png

toxic wagon Oct 29, 2017, 2:56 AM

#

you know

light thunder Oct 29, 2017, 2:57 AM

#

Like, what is the difference between load level and open level???

marble lynx Oct 29, 2017, 2:58 AM

#

I'm not 100% sure, but I'm pretty sure Open Level changes the level

#

as if you hit File -> Open

#

so you're undoing all the work you've been doing

#

Load Stream Level, is streaming in an additional level on top of your already loaded ("Opened") initial level

#

but Open Level only works when running the game, in PIE it does nothing because you can't change the level in PIE like that

#

so you should only be using Load Stream Level I believe

#

Streaming volumes are used to control the way a map loads in or out. With some additional parameters outside of your basic Blueprint Load/Unload commands. It's a way to automatically stream in/out stuff based on distance mostly

light thunder Oct 29, 2017, 3:03 AM

#

Hmmm....I have this huge map that's an optimization nightmare because I'm a firefighter and not a developer.... I wonder how I could use level streaming to fix this without dragging everything to a different level

📎 2017-10-28_2145.png

marble lynx Oct 29, 2017, 3:05 AM

#

which stat profiler are you using in that screen?

#

Memory?

light thunder Oct 29, 2017, 3:05 AM

#

rhi

#

that just shows there is no culling going on

#

or at least, as far as I understand, no distance-based culling...there is some occlusion culling down below

fiery harbor Oct 29, 2017, 3:07 AM

#

I dont see how level streaming would be of use in such a small level

marble lynx Oct 29, 2017, 3:07 AM

#

if that's your view in the game

#

level streaming isn't going to help you much if at all

light thunder Oct 29, 2017, 3:08 AM

#

um, that's the sky view @fiery harbor It is pretty big

#

nope, that was just to test

fiery harbor Oct 29, 2017, 3:08 AM

#

it doesn't look big

light thunder Oct 29, 2017, 3:08 AM

#

Here, see the buildings in the background

📎 2017-10-28_2124.png

fiery harbor Oct 29, 2017, 3:08 AM

#

its less than 1km * 1km

marble lynx Oct 29, 2017, 3:08 AM

#

well CULLING is done based on obstruction

light thunder Oct 29, 2017, 3:09 AM

#

That's why I mentioned my understanding...there are plenty of tutorial videos on lighting, level streaming, and optimization, but doesn't seem to be a video on just 'Understanding Culling"

marble lynx Oct 29, 2017, 3:09 AM

#

you don't need to understand a lot, it's really done by the engine automatically. If you can't see an object, it culls it. If you see part of the object, it loads the entire object. That's about all you need to know

fiery harbor Oct 29, 2017, 3:11 AM

#

its a bit more stupid than that

#

it happens a lot that stuff thats completely invisible is not culled by the occlusion culling

light thunder Oct 29, 2017, 3:11 AM

#

Well, my problem is there is no fade distance, I can see for a long way away so I'm rendering a bunch of unnessary stuff

fiery harbor Oct 29, 2017, 3:12 AM

#

then just set some distance culling up?

light thunder Oct 29, 2017, 3:12 AM

#

is there a way to do that without editing hundreds of actors, other than using a culling volume

marble lynx Oct 29, 2017, 3:12 AM

#

usually the biggest performance issue comes from lighting, you either have really bad lightmaps, unbuilt lighting, too many dynamic lights or really poorly made models get clogged up by the engine. Also make sure your terrain isn't set to incredibly dense

fiery harbor Oct 29, 2017, 3:12 AM

#

whats the problem with using a culling volume?

marble lynx Oct 29, 2017, 3:13 AM

#

because you're always rendering huge chunks of the terrain

light thunder Oct 29, 2017, 3:13 AM

#

lighting is unbuilt

marble lynx Oct 29, 2017, 3:13 AM

#

use Alt-8 to go into Shader Complexity mode, Green = Good, Red/White = Very Bad

fiery harbor Oct 29, 2017, 3:13 AM

#

@marble lynx he has 20 million triangles and 56k draw calls in his first screenshot, its not the lighting that makes it slow

light thunder Oct 29, 2017, 3:13 AM

#

i get these shader errors

#

Yes, what @fiery harbor said

marble lynx Oct 29, 2017, 3:14 AM

#

Well yeah, 30 million triangles is gonna take a hit to most systems.

#

Especially without built lighting

#

but his first person view showed about 7 million

#

Which is still kind of high for the kind of detail in the photo

#

What's really throwing a flag is your Primitives Call to me, that number is super high I feel like.

light thunder Oct 29, 2017, 3:15 AM

#

Most of the foliage is static instances

#

This is the stuff I need to understand

#

I found that a fair portion of my assets were not optimzied, I was using prefabed blueprints for buildings

#

Merging the actors helped some

marble lynx Oct 29, 2017, 3:17 AM

#

Can you show us the wireframe of roughly the same view you showed last?

I dont think thats an issue

marble lynx Oct 29, 2017, 3:20 AM

#

So you may be having some performance issues from those foliage actors, it looks like they were poorly setup

#

Overall you don't have a lot of detail in that scene, right? Not really.

#

But your drawcall is still 2.5k

light thunder Oct 29, 2017, 3:21 AM

#

correct, a few particle emitters

marble lynx Oct 29, 2017, 3:22 AM

#

📎 Culling.jpg

#

Now here's a scene I'm working on, there's a bit of BSP, and simple meshes. But nothing is optimized at all yet, I have 3 detailed vehicles

#

and some windows

#

but my draw call for primitives hasn't even hit 600 yet, even though my triangles are about 1mil

fiery harbor Oct 29, 2017, 3:23 AM

#

@light thunder how many particle emitters?

light thunder Oct 29, 2017, 3:24 AM

#

what is wrong with the foliage ? what do you need to see?

📎 2017-10-28_2322.png

#

@fiery harbor just a few on that....but they don't appear to be the issue

#

I wish it were JUST particle emitters

marble lynx Oct 29, 2017, 3:24 AM

#

the engine and computers are great at rendering large amounts of triangles these days, but it's the amount of draw calls you have to watch out for. 1 Million with 1 draw call is way easier to handle than 500k with 30 draw calls

fiery harbor Oct 29, 2017, 3:24 AM

#

particle emitters cause a lot of draw calls and often have huge bounding boxes

light thunder Oct 29, 2017, 3:25 AM

#

those draw calls are from the editor, the particle is not even activated so it's not even doing the draw call

fiery harbor Oct 29, 2017, 3:25 AM

#

ah

#

@marble lynx the difference between 1 and 30 draw calls is not really relevant

#

difference between 500k and 1 million triangles or more relevant

#

I try to stay below 1 million triangles and below 600 draw calls

marble lynx Oct 29, 2017, 3:28 AM

#

For the most part, but the idea behind Instanced Static Meshes and Material Instances is that you're limiting the number of draw calls that take up memory overall.

#

or at least from what I understand

fiery harbor Oct 29, 2017, 3:28 AM

#

material instances don't have anything to do with draw calls

#

they are only for easier configuration of materials

#

its still 1 draw call per material per mesh

#

for every time its rendered

marble lynx Oct 29, 2017, 3:30 AM

#

Hmm, I'll have to look into that more. But I always undestood it as if you have 2 material instances, and you're changing say a Brightness Parameter, the engine only has to load 1 Material, and simpy swap out basic values. Comapred to if you copy the same material twice, and set the brightness to different values inside the material

#

meaning less memory usage

fiery harbor Oct 29, 2017, 3:31 AM

#

memory usage for materials is completely irrelevant

marble lynx Oct 29, 2017, 3:31 AM

#

which is why you don't have to recompile when you change values in an Instance versus inside a material. It's already loaded

fiery harbor Oct 29, 2017, 3:31 AM

#

materials instances are slightly more expensive than regular materials actually because a dynamic parameter in a material is a bit slower to process than a static one

marble lynx Oct 29, 2017, 3:31 AM

#

Hmm

#

WEll!

#

Back to the matter at hand

#

having 10k unbuilt objects is going to be hefty on the system

#

from lighting

#

and you have a super high amoutn of draw calls for a relatively simple view

light thunder Oct 29, 2017, 3:32 AM

#

so how do I build it without taking forever....can I build an area at a time without setting up level streaming just yet?

fiery harbor Oct 29, 2017, 3:33 AM

#

the level still looks pretty small, is it an issue to build it at once?

light thunder Oct 29, 2017, 3:33 AM

#

the level is big man

how big is it?

light thunder Oct 29, 2017, 3:34 AM

#

What do you guys think? swarm says (it's been building for about 7 minutes) it's at .25 percetn

#

which I'm fine with going to bed to have this finished

#

but that's only at preview quality too

#

I'm not 100% sure if this is true, but I believe lighting takes longer when you have improper lightmaps, or no lightmaps at all

light thunder Oct 29, 2017, 3:35 AM

#

how do I, um, build lightmaps

marble lynx Oct 29, 2017, 3:36 AM

#

but typically the first 20% takes a bit to get going, then it goes through pretty quickly and then sits 99% for a long while (if the lightmaps aren't right) before it finalyl releases the build

#

Basically all your static objects, need to have a 2nd UV spot in them, and that should contain 100% unique UVs, no overlapping, no mirroring, no shared UV space at all

#

the engine automatically takes the 2nd UV space, and applies lightmap data to it when it builds

light thunder Oct 29, 2017, 3:36 AM

#

well there's like some with 44% overlapping UV's

marble lynx Oct 29, 2017, 3:37 AM

#

Yeah, any overlapping causes havoc on the build basically. Because it bleeds around the edges, and tries to light every face. But if there is already data there it sort of goes haywire

#

typically causes lots of issues

light thunder Oct 29, 2017, 3:40 AM

#

is there things I can do in Unreal while it builds lights?

#

I can make assets like blueprints or widgets though I can't play anything

marble lynx Oct 29, 2017, 3:40 AM

#

It'll make the build go slower, and more prone to crash. But technically you can

light thunder Oct 29, 2017, 3:42 AM

#

I never could get swarmagent to network up

#

I have a decent 3 year old Sager gaming laptop that'd I would love to hook up while I'm baking lightgs

ripe plover Oct 29, 2017, 4:04 AM

#

Making a building.. Read somewhere using brushes is not a very good idea. Any resources/help on how to get started making structures properly if my way is not correct? (I do not want to develop bad habits or kill game performance doing something incorrectly.) Any help appreciated thanks
I was also hoping to have all my brushes attached so I could reuse the building elsewhere as an asset but I heard you can't attatch brushes to other brushes.

P.S: I am new to UE4 (Started Yesterday) So dumb it down for me please 😛

PUBG is a game about running away from a sphere collider, and an if statement ... if playersAlive <= 0 && PlayerAlive[0] == this {ShowVictoryScreen();}

#

Anyone notice that?

light thunder Oct 29, 2017, 4:35 AM

#

@ripe plover Check Youtube, there's a bunch of videos for the best practices to creating content, also you can get free assets from Epic from all their content examples and some of their projects they put out. I'd look at the materials videos they have too

#

@marble lynx So wait, if I put a Culling Volume on the ENTIRE LEVEL and I put the size to cull like 5000 to grab every object basically and I put the culling distance to like, 5000 as well, that will cull EVERYTYHING (that is the size of 5000) around player right since it is based off camera distance?

#

Btw, that lighting build helped a lot....I'm not sure but I think I'm hitting 90 fps, it was stopping at 45 and I think that's because of Steam VR 's stuff

ripe plover Oct 29, 2017, 4:40 AM

@light thunder Thanks dude can you confirm if brushes are a bad route though?

#

Ill go look for yt vids

light thunder Oct 29, 2017, 4:49 AM

#

@ripe plover There are many who know much more, jcheck the graphics room, my understanding is that you shouldn't rely on them as a main thing, they are good for a small bit of detail or in a pinch when you have to see how something would look

#

Advice: watch the livestreams one a monitor and follow through with them, pausing when you need to

fiery harbor Oct 29, 2017, 4:49 AM

@light thunder as I said in #virtual-reality, you are not hitting 90 fps if you are at 45 fps. at 45 fps you are at 45 fps

sudden agate Oct 29, 2017, 7:40 AM

Your textures are done in a third party app (Substance Painter or Mudbox or ZBrush for example) while your actual Material is done in UE

#

@drowsy sage it's a Transform node

regal mulch Oct 29, 2017, 8:30 AM

#

@scarlet grove You could make your own collider child class (component) and use that. A linetrace should return the hit component too, so you can call your own function on that. Or you pass it via the interface and let the actor check what was hit. Not so beautiful with a lot of components though

keen birch Oct 29, 2017, 8:30 AM

#

Alright, guys

#

I'm a bit stuck on something

#

Games like Pokemon SNAP detect what's in the current FOV, and where in said FOV it is - how would you go about implementing something like that

#

Can I access a list of all objects being rendered?

#

And how big they are on-screen?

regal mulch Oct 29, 2017, 8:36 AM

#

I think actors have a "recently rendered" or "time since last render" thingy

#

That should technically tell you if the actor is in view or not

so I ran into interesting issue yesterday, is BSP collision evaluated just once?

BSPs are static

#

hey I'm kinda new to UE4

#

have a small question

#

is it possible to have UE4 run as smoothly as Warframe's Evolution Engine?

#

if yes, how complicated is it?

#

is it a relatively automated function in UE4 or do I have to edit source, etc?

tall pendant Oct 29, 2017, 10:09 AM

#

depends on your hardware target i guess

paper kernel Oct 29, 2017, 10:09 AM

#

short answer is probably not possible

midnight mantle Oct 29, 2017, 10:09 AM

#

I see

paper kernel Oct 29, 2017, 10:10 AM

#

Evolution engine is specific purpose engine for the game, UE4 is more generic

quasi lake Oct 29, 2017, 10:10 AM

#

Anyone knows something about rootmotion?

midnight mantle Oct 29, 2017, 10:10 AM

#

so I should probably use the least amount of meshes and textures, etc for lower end hardware ?

quasi lake Oct 29, 2017, 10:10 AM

#

I have enable rootmotion in my animation.

paper kernel Oct 29, 2017, 10:11 AM

#

there's million and one things to optimize for lower hardware, but if you're new to the engine don't sweat it yet

midnight mantle Oct 29, 2017, 10:11 AM

#

okay

tall pendant Oct 29, 2017, 10:11 AM

#

Well they did Dark Sector with their Engine 😛

paper kernel Oct 29, 2017, 10:12 AM

#

iirc original warframe was made with UE3

#

and they ported it to inhouse engine later in major patch

quasi lake Oct 29, 2017, 10:12 AM

#

But I didnt work

midnight mantle Oct 29, 2017, 10:12 AM

#

interesting

#

but UE3 was completely different

tall pendant Oct 29, 2017, 10:13 AM

#

Evolution and UE3 share some similarities... which makes sense since DE was a partner of Epic for earlier UE versions.

paper kernel Oct 29, 2017, 10:13 AM

#

yea I belive they derived their own engine from UE3

#

but man that engine runs fast

I think I got like +300fps on SLI setup

Everything seems a bit nicer when you actually introspect and look at others' successes in a constructive manner instead of just bitching. :)

plush yew Oct 29, 2017, 3:07 PM

#

has nothing to do with the game itself... if i made OverWatch before blizzard, exact copy paste of it... it wouldnt be popular... because im not blizzard

#

lol

#

For example, I know that I could dedicate my whole life to something and never come close to the positive attributes gained from being "Blizzard" simply because I'm not blizzard. Even if my games were of equal polish and quality, which they aren't currently, but if they were, they would still not make nearly as much money as blizzard.

#

Lol

#

@glossy flame Oh yeah, the thing is, you don't really get to see the story of success, and how it happened most of the time, you only get to see the end result which kind of sucks. Lots of people I know who Ifor example have tons of YouTube subs I would ask them "How did it happen" and they reply with "I don't know." Because success is RNG based.

The world of games does not reward the best maker, it rewards the most well known maker. Not just in games, but in life in general, the best person doesn't get the golden medal... It's the best "most known" person who gets the medal.

I'm sure there's better swimmers than Michael Phelps for example, but hes the most well known swimmer in american olympics.

#

You know what I mean?

#

The most known + best gets the medal, that doesn't mean hes the best though

#

It just means hes the most bestest known

#

lol

glossy flame Oct 29, 2017, 3:12 PM

#

Uh...not really, rofl.

#

That's pretty off topic though

#

There's no argument that big brands get recognition, but how do you think those brands came to be?

#

By making complete garbage?

plush yew Oct 29, 2017, 3:13 PM

#

Nope.

#

I'm just saying that if I made an exact copy of some of those games which they make... i wouldnt get nearly the press coverage as they do

#

Even though its an exact copy

upper heart Oct 29, 2017, 3:14 PM

#

There is beauty in making games regardless of success/money/recognition.

ionic sedge Oct 29, 2017, 3:15 PM

#

It's more subjective than something like sports though. It's like music, what's the best? You can think of it as a preference or what makes the most money.

#

(mainstream appeal)

#

In that sense PUBG is appealing to a lot of people. 😛

#

But you could as well make a super niche game and if it was good it would probably still sell.

thorny kayak Oct 29, 2017, 3:18 PM

#

I don't know about that

#

If the marketing is right, then maybe. But these days it's really difficult to even find good games. There are so many of them.

#

Also, it's fun to make games, but if you intend to do it as something other than a hobby, then you need your games to sell.

#

But hey, I know people don't want to hear my depressing rants so I'll just shut up. 😄

plush yew Oct 29, 2017, 3:20 PM

#

aWell I don't think the success, and profitablility of a game is based around it being unique.

#

I feel like a lot of people try to make a "unique" game and it ends up being forced, and they just make a fool of themselves.

#

I think that, if you just copy a genre which exists already, and make a few changes... you will ALWAYs get some minor, or major changes from the thing you are basing it on.

thorny kayak Oct 29, 2017, 3:21 PM

#

Absolutely

plush yew Oct 29, 2017, 3:22 PM

#

Like for example, League of Legends vs Dota... very similiar games, but one big difference is that league has no turn speed on your heroes, which is a massive difference.

thorny kayak Oct 29, 2017, 3:22 PM

We released a game this year on Steam called Riptale and... I mean I think it's a fun game to play and it sold ok, but not enough to keep us in business.

#

Sold ok as in if my albums sold anywhere near that number of copies, it'd be a miracle.

#

There are just so many games and if you don't get into that loop of popular gamers playing it, then it just doesn't go anywhere.

(in seconds)

sudden agate Oct 29, 2017, 8:30 PM

#

InterpTo Speed Constant: = 1sec/ (Speed/100) = Time to reach Target

#

dunno about Interp To (without Constant) tho

#

@zinc bison

feral echo Oct 29, 2017, 8:31 PM

#

most of time its movement speed

#

I suppose

zinc bison Oct 29, 2017, 8:31 PM

#

so in your equation, Speed = InterpSpeed?

sudden agate Oct 29, 2017, 8:32 PM

#

no.
If you put 100, you need 1 Second to reach Target.
If you put 200, you need 0,5 seconds to reach target
If you put 300, you need 0,33333 seconds to reach target and so on

zinc bison Oct 29, 2017, 8:33 PM

#

what is the interpspeed in your equation, this is what Im asking you. Are you saying interpSpeed is the speed constant?

sudden agate Oct 29, 2017, 8:33 PM

#

There are two Interp To Nodes:
InterpTo
and
InterpTo Constant

zinc bison Oct 29, 2017, 8:33 PM

#

im using C++, but yes I know

#

Im trying to understand your equation because you do not actually have InterpSpeed in that equation anywhere

sudden agate Oct 29, 2017, 8:34 PM

#

when using the Constant version,
Time to reach Target = 1/(Speed/100)

zinc bison Oct 29, 2017, 8:34 PM

#

Okay so Speed == InterpSpeed

#

thank you

#

and "time to reach target" is in seconds Im assuming.... I should just read the source.

#

also why do they make it such an annoying equation to deal with

#

as far as the inputs go, they should have been able to make it simplier for the user. Thats kinda the whole point of the math library

#

Do you guys know if it's possible to let the player see in Wireframe mode while actually in-game in a shipping build?

#

I know you can execute a command to do this but I have to assume it would only work on a Development build and not in an actual Shipping build for consumers

paper kernel Oct 30, 2017, 9:10 AM

#

I think not, but making a wireframe material shouldn't be too hard

wary wave Oct 30, 2017, 9:10 AM

#

wireframe is a material type

#

also, I see no reason you couldn't ship with that console command enabled, but this will likely involve code

tidal bluff Oct 30, 2017, 9:10 AM

#

wireframe is hidden in the content browser right?

wary wave Oct 30, 2017, 9:11 AM

#

huh?

#

what's the content browser got to do with it?

tidal bluff Oct 30, 2017, 9:11 AM

#

nvm

#

"making a wireframe material"

#

iirc in the hidden content browser, the actual material for wireframe view is in there right? I havent dug into it for a while, but you can find things like a "wave material" and other example materials in there

wary wave Oct 30, 2017, 9:13 AM

#

https://snag.gy/cxShTJ.jpg

#

it's just a flag in a material

#

the actual wireframe view I don't think is a material

tidal bluff Oct 30, 2017, 9:15 AM

#

oh, definitely not the view no

#

it wouldnt give good player feedback anyway

ruby chasm Oct 30, 2017, 9:27 AM

#

I want to have my entire map be wireframe

#

And then switch over to the regular view mode

#

To create a transition that looks like you're loading into a simulation

#

I have a lot of different assets in the game so switching the mats on everything would be a pain

#

I also noticed a performance drop while simulating in wireframe, not sure if that's meant to be happening (maybe because you can see through objects)

wild ivy Oct 30, 2017, 9:32 AM

#

hey guys!

#

i have a prob. so im doing this (https://docs.unrealengine.com/latest/INT/Gameplay/HowTo/CharacterMovement/Blueprints/index.html) tutorial, and however, when i press "c", it will slow down the movement speed to 160 as it should, but it wont play any animation.. so the transition works fine, but the anm

#

but the animation doesnt

ruby chasm Oct 30, 2017, 9:36 AM

#

So you slow down the character but the animation still plays at full speed

#

Can you show us your BP?

#

@wild ivy

wild ivy Oct 30, 2017, 9:37 AM

#

oh sorry, forgot to mention that im talking about the crouch

#

so it slows down, but keeps standing

ruby chasm Oct 30, 2017, 9:37 AM

#

Oh so it doesn't play the crouch animation

wild ivy Oct 30, 2017, 9:37 AM

#

yup

ruby chasm Oct 30, 2017, 9:37 AM

#

Alright, easy fix

#

1 sec

wild ivy Oct 30, 2017, 9:37 AM

#

want me to send bp screens?

ruby chasm Oct 30, 2017, 9:38 AM

#

No, go into your state machine in the anim graph of your AnimBP

#

And show me that

#

Do you have a transition set to rely on a boolean?

wild ivy Oct 30, 2017, 9:39 AM

#

📎 statemachine.png

#

im new to ue4, so it looks a bit messy

ruby chasm Oct 30, 2017, 9:40 AM

#

All of your transitions are being handled by bools?

#

The little circles next to the connecting lines are the transitions

wild ivy Oct 30, 2017, 9:40 AM

#

kind of yeah

#

ikik

#

i set the transition rules like the docs told me

ruby chasm Oct 30, 2017, 9:41 AM

#

Alright, now those bools need to be set elsewhere so that the transition can happen

#

Otherwise it'll never go from walking to crouching

#

And back

#

Is that happening anywhere?

wild ivy Oct 30, 2017, 9:42 AM

#

but if it wouldnt, than it would also not slow down like it should right?

ruby chasm Oct 30, 2017, 9:42 AM

#

The speed of your character likely isn't being set in the AnimBP anyways, right?

#

You're probably doing that in your character's BP

wild ivy Oct 30, 2017, 9:42 AM

#

yup#

ruby chasm Oct 30, 2017, 9:42 AM

#

That speed change doesn't rely on the AnimBP, the AnimBP will only control the animation which is why the speed is changing but the animation isn't

#

That transition isn't being allowed to happen

#

Somewhere else in your BPs you'll need to call out to the AnimBP and tell it that you're now crouching

#

I'm assuming that was covered in the tut, do you remember?

wild ivy Oct 30, 2017, 9:43 AM

#

i hope that is what you mean

ruby chasm Oct 30, 2017, 9:45 AM

#

Ah there we go

#

Both of your Crouch bools are being set to false. One of them needs to be set to True

#

The one that would = crouching

#

Based on speed

wild ivy Oct 30, 2017, 9:45 AM

#

so the upper one?

ruby chasm Oct 30, 2017, 9:45 AM

#

Yeah

#

And if you set up the transition to go back into walking, the second time you press C it would switch everything back

#

Speed + Anim

#

Try it out, let me know

wild ivy Oct 30, 2017, 9:47 AM

#

just did, and still.. its slowing down, but not showing the animation

ruby chasm Oct 30, 2017, 9:47 AM

#

there are a few places I'd check, do you have TeamViewer or something?

#

You may also not be checking this variable from the AnimBP so the AnimBP has no idea you've set it

#

Do you remember setting that up in the AnimBP?

wild ivy Oct 30, 2017, 9:51 AM

#

gonna dig myself a hole 😄

ruby chasm Oct 30, 2017, 9:51 AM

#

Instead of linking them up like that, use a 'Sequence' node

#

It basically lets you output as many pins as you need and is useful in cases like this. Your method should also work but Sequence nodes are clean 👌

wild ivy Oct 30, 2017, 9:53 AM

#

📎 docs.png

#

thats why i did it 😛

ruby chasm Oct 30, 2017, 9:53 AM

#

Personal preference I guess haha

wild ivy Oct 30, 2017, 9:54 AM

#

not skilled enough to think on my own, so i just followed the docs

#

but what do you mean by "Sequence Nodes"? 😃

sudden agate Oct 30, 2017, 9:54 AM

#

There's a Node "Sequence" which has multiple output pins and are executed one after another

ruby chasm Oct 30, 2017, 9:54 AM

#

If you right click and type in 'Sequence' you'll see a Sequence node. One example of its use:
You want multiple things to fire off at the same time on BeginPlay, you drag out from BeginPlay into a Sequence node and fire off all of them at once.

#

^

#

Oh I thought it was simultaneous but that's silly

#

What he said ^

wild ivy Oct 30, 2017, 9:55 AM

#

If you fire all of them at once, doesnt that set all Vars to true?

ruby chasm Oct 30, 2017, 9:56 AM

#

With your current set-up, you're firing off the first node and every node after without anything to stop them anyways

#

The only reason they aren't all being set to True

#

Is because they're checking your pawn

#

To see if they should be

#

So a Sequence node would fire them all off but only set them if the Pawn needs them to be

#

No difference

#

Jump Pressed = Jumping. If Jump Pressed = False, Jumping also = False but it's still firing off to check for which

#

I know it might be kind of confusing but when it sinks in you'll never forget it

wild ivy Oct 30, 2017, 10:01 AM

#

so relating to the last screen, what do i connect the sequence with?

ruby chasm Oct 30, 2017, 10:01 AM

#

from Set Speed

#

enter a Sequence

#

Then, make sure the Sequence has 4 output pins

#

Connect each one to Is Crouching, is Jumping, etc. one per

#

You don't have to do it but, good practice if anything.

wild ivy Oct 30, 2017, 10:03 AM

#

like this?

#

📎 seqprac.png

ruby chasm Oct 30, 2017, 10:03 AM

#

Yeah, perfect

wild ivy Oct 30, 2017, 10:03 AM

#

ok lemme test it 😃

#

it works 😄

ruby chasm Oct 30, 2017, 10:04 AM

#

So what you're doing here is, your AnimBP will constantly fire those off and every time it does, it'll check your Pawn BP to see if any of those buttons were pressed. When you connect a 'Get Bool' into a 'Set Bool', it's basically checking 'Is bool #1 True?' if so, Set the bool its connected to to true.

but char movement is a variable 😮

ruby chasm Oct 30, 2017, 10:11 AM

#

All you're doing is checking to see if your pawn is falling

#

Yeah?

#

Pawns have Movement Components so to check for 'Is Falling', you'd need to go through that movement component

wild ivy Oct 30, 2017, 10:12 AM

#

woah its done!

ruby chasm Oct 30, 2017, 10:12 AM

#

👌

wild ivy Oct 30, 2017, 10:13 AM

#

so can i use the "is falling" to respawn a player if he is falling for more than 3 seconds?

ruby chasm Oct 30, 2017, 10:13 AM

#

Can you tell me where this might happen? Like if he's falling off a cliff or something where he shouldn't be?

wild ivy Oct 30, 2017, 10:14 AM

#

well for now, my map is just a flat box 😄

#

so you can fall down anywhere basically

ruby chasm Oct 30, 2017, 10:14 AM

#

What you can do is create a new actor BP and inside that, create a Trigger Box. Then generate an overlap with the player. If this happens, respawn him. Place that box and stretch it out below your map so when he falls off, he'll overlap and respawn.

#

In that actor, you'd basically do:
On BeginOverlap (from the trigger box) > Cast to pawn, use it as 'Other Actor' > respawn logic

#

It would only fire off when that pawn you cast to overlaps that box.

wild ivy Oct 30, 2017, 10:16 AM

#

so as soon as the player box and the respawnBox collide, it respawns the player to his starting entity?

ruby chasm Oct 30, 2017, 10:16 AM

#

Yes, well you'll have to 'move' the player to a predetermined location of your choice (the respawn point)

#

Or to be more specific, you would 'Set Location' for the player

#

All of this would be done inside that box

wild ivy Oct 30, 2017, 10:16 AM

#

and enter x,y,z

ruby chasm Oct 30, 2017, 10:16 AM

#

Exactly

wild ivy Oct 30, 2017, 10:16 AM

#

ahh

#

maybe im just thinking way to complicated

ruby chasm Oct 30, 2017, 10:17 AM

#

You could do like a Portal type effect even with this method, as an example

Enter the trigger box, teleport to XYZ

It's cool, once you understand the basics you'll be able to do a lot

ruby chasm Oct 30, 2017, 10:51 AM

#

@wild ivy Not collision. Overlap

#

I'll show you, one sec

wild ivy Oct 30, 2017, 10:53 AM

#

SetActorLocation?

ruby chasm Oct 30, 2017, 10:53 AM

#

#

To get that first node, click on the trigger box component and in the details panel, scroll to the bottom

#

Click on 'on Begin Overlap'

#

It'll create it for you.

#

'Sniper Pawn' is the name of my pawn, ignore that particular name

wild ivy Oct 30, 2017, 10:55 AM

#

i did that

#

doesnt work though

#

ahh now it does, forgot to link cast and setActorLocation(target)

#

thanks alot for everything 😃

ruby chasm Oct 30, 2017, 10:56 AM

#

how can I fix it?

ruby chasm Oct 30, 2017, 11:05 AM

#

Hmm

severe glen Oct 30, 2017, 11:05 AM

#

Its about collision

#

I guess

ruby chasm Oct 30, 2017, 11:05 AM

#

No,

#

Are you attaching the actor to the chair?

severe glen Oct 30, 2017, 11:05 AM

#

no

#

I just use respawn class

#

It respawn at the Target point

ruby chasm Oct 30, 2017, 11:06 AM

#

You can try offsetting that target point, up a little higher and pull it back

severe glen Oct 30, 2017, 11:06 AM

#

I did it already 😃

ruby chasm Oct 30, 2017, 11:06 AM

#

Or push the chair in

#

It's kind of far back

severe glen Oct 30, 2017, 11:06 AM

#

I have 20 character actually

#

and they respawn on chairs

#

but someone overlapping on chair

#

should I use physic animation?

wary wave Oct 30, 2017, 11:08 AM

#

no, you should fix your animations and make them match the chairs.

#

if they already match the chairs, then your target point is wrong - but I suspect the problem is the anims

severe glen Oct 30, 2017, 11:10 AM

#

I just when her hip colliding on chair It should be stop fall dawn

#

I guess when her foot colliding on floor its stopped

#

📎 unknown.png

#

this is my collision settings for chair

#

📎 unknown.png

#

and this is my character colliison settings

wary wave Oct 30, 2017, 11:28 AM

#

I'm pretty sure the animation does not match the chair

severe glen Oct 30, 2017, 11:35 AM

#

I dont think so . the problem should be colliison presets

wild ivy Oct 30, 2017, 12:31 PM

#

what is the best and cheapest way to create models for ue4?

#

best would be free?

wary wave Oct 30, 2017, 12:33 PM

#

Blender and lots of learning.

tall pendant Oct 30, 2017, 12:35 PM

#

best and cheapest are pretty contradictory tho

wild ivy Oct 30, 2017, 12:36 PM

#

how much is blender?

tall pendant Oct 30, 2017, 12:36 PM

#

free

wild ivy Oct 30, 2017, 12:36 PM

#

i just need 1 basic model for testing purposes

frank escarp Oct 30, 2017, 12:36 PM

#

Blender no doubt

#

Free, 200 dollars

#

also check the unreal engine samples, maybe there is something you can use

#

for example i use infinity blade asset pack in DWVR

wild ivy Oct 30, 2017, 12:37 PM

#

where do i find that?

frank escarp Oct 30, 2017, 12:37 PM

#

Learn tab in launcher

#

or Marketplace and filter through the Free stuff

honest raven Oct 30, 2017, 1:21 PM

#

Guys is it hard to "update" a project? Like a 4.17.2 version to 4.18?

#

Or possible in the first place?

grim sinew Oct 30, 2017, 1:23 PM

#

If you're using C++ it gets significantly harder. Otherwise, just open the project with 4.18 and the engine should do its best to update.

tall pendant Oct 30, 2017, 1:24 PM

#

its possible. depending on some stuff it can be easy to a pain in the a..

honest raven Oct 30, 2017, 1:26 PM

#

Hmm

#

I do not have c++ azm

#

Atm

#

But I had a project in 4.16 and tried to upgrade it to 4.18 but its wasnt succesful

#

:(

#

Wanted me to rebuild the source manually

#

But as ai said I am using pure blueprint

grim sinew Oct 30, 2017, 1:27 PM

#

That doesn't sound right

frank escarp Oct 30, 2017, 1:30 PM

#

actually not really

#

its much easier to update a C++ project

#

becouse you just search and replace compiler errors or api changes

#

and you are done

#

(mostly)

#

but blueprints..

#

blueprints fail silently on your back

#

they get unplugged and things like that

#

thats from my DWVR stuff, wich has been updated from 4.7 to 4.16

#

C++ has never been any issue

#

other than a couple compiler errors trivial to fix

#

but blueprints getting fucked? constantly

cloud cobalt Oct 30, 2017, 1:36 PM

#

As a C++ person I can attest that migrations are usually fast and smooth

#

Over more than 10 version updates, I think two required large changes. One was the new audio pipeline, making our audio settings code obsolete, and another was input-related and pretty painful, but mostly because of us

#

Other updates were just a search&replace job

wary wave Oct 30, 2017, 1:54 PM

#

depends on your changes really - if you for example make changes to the renderer, you can be in for a fun time sometimes

clever quartz Oct 30, 2017, 2:33 PM

How do I attach a PlayerController to the FirstPersonCharacter in the FirstPersonExampleMap, I tried dragging my controller to the FirstPersonCharacter but for some reason when I press play it creates another FirstPersonCharacter without my controller attached, if I didn't explain it well I can take a screenshot

ionic sedge Oct 30, 2017, 2:43 PM

#

You go to the project settings, maps and modes, expand the selected gamemode and change the player controller class.

#

@clever quartz

clever quartz Oct 30, 2017, 2:43 PM

#

thanks, I'll check that out then

clever quartz Oct 30, 2017, 3:39 PM

#

@ionic sedge so umm I can't seem to find a way to change any of those settings? They are all greyed out https://i.imgur.com/X1f6l3t.png

Imgur

#

only the + works but it just creates a new blueprint and no way to add it

ionic sedge Oct 30, 2017, 3:40 PM

#

Is that some template project?

clever quartz Oct 30, 2017, 3:40 PM

#

yes

ionic sedge Oct 30, 2017, 3:41 PM

#

You can see if you can find the MinecraftGameMode BP somewhere, then open that, you should be able to set the defaults there.

clever quartz Oct 30, 2017, 3:41 PM

#

cheers

ionic sedge Oct 30, 2017, 3:43 PM

#

If you can't do that there you can duplicate it and reassign it in the maps and modes panel, then you should be able to change them.

clever quartz Oct 30, 2017, 3:43 PM

#

okay, I'll have a look, thanks for the help

plush yew Oct 30, 2017, 4:11 PM

#

@tall pendant blender costs 1999 USD. but for nice people it costs nothing

#

hey any good programs i should use for level design like for making props buildings etc

plush yew Oct 30, 2017, 4:35 PM

#

blender

next badger Oct 30, 2017, 4:36 PM

#

@plush yew free or paid?

plush yew Oct 30, 2017, 4:39 PM

#

Well ill be damned

#

free for now

#

My apologies

#

You have my respect now

next badger Oct 30, 2017, 4:40 PM

#

@plush yew blender then

#

@plush yew what Victor did....again...?

plush yew Oct 30, 2017, 4:40 PM

#

He won a mega game jam

#

That takes talent

next badger Oct 30, 2017, 4:40 PM

#

already????

#

it's not started yet

plush yew Oct 30, 2017, 4:41 PM

#

No he won one before apparently

#

Theres more mega jams

next badger Oct 30, 2017, 4:41 PM

#

oh...i think he won many

plush yew Oct 30, 2017, 4:41 PM

#

Damn

#

Thats incredible

#

Oh mb normal game jams

#

Not mega

#

But still

wild ivy Oct 30, 2017, 5:07 PM

#

Can someone explain to me what this does? Thanks 😃

safe rose Oct 30, 2017, 5:09 PM

#

@wild ivy The tutorial that you are following tells you what it does

#

I am assuming that's from the official docs?

wild ivy Oct 30, 2017, 5:09 PM

#

It is, but still dont quite get it

safe rose Oct 30, 2017, 5:10 PM

#

?

wild ivy Oct 30, 2017, 5:10 PM

#

It explains what it does

safe rose Oct 30, 2017, 5:10 PM

#

You don't get what exactly

#

k

#

So, my assumption is you are relatively new to UE4?

wild ivy Oct 30, 2017, 5:10 PM

#

Exactly

safe rose Oct 30, 2017, 5:10 PM

#

So, you shouldn't be doing this then

#

No offense

#

Start off a little less hardcore

wild ivy Oct 30, 2017, 5:10 PM

#

Isn't AI something you should know?

safe rose Oct 30, 2017, 5:11 PM

#

There's a lot of intermediate stuff going on there

#

Of course...

#

But not as a newb

wild ivy Oct 30, 2017, 5:11 PM

#

Oh

safe rose Oct 30, 2017, 5:11 PM

#

There are so many fundamentals you need to get ahold of first

#

📎 unknown.png

#

Do you know what that does?

wild ivy Oct 30, 2017, 5:12 PM

#

It refers the object input to The ai controller and sets the ai con ref var

#

Right?

safe rose Oct 30, 2017, 5:12 PM

#

hmmm

#

no

wild ivy Oct 30, 2017, 5:12 PM

#

Duhh 😦

safe rose Oct 30, 2017, 5:12 PM

#

I mean, do you know what it's doing actually?

#

What is it setting?

#

📎 unknown.png

#

What that is?

#

The blue data wire

wild ivy Oct 30, 2017, 5:13 PM

#

Its passing on the value?

#

Oh fuck me i have no clue

safe rose Oct 30, 2017, 5:14 PM

#

Do you know what Object references and Class references are?

#

And the difference

wild ivy Oct 30, 2017, 5:14 PM

#

Yyyyes. No. Yes. Idk

safe rose Oct 30, 2017, 5:14 PM

#

What about Instances of an Object?

wild ivy Oct 30, 2017, 5:15 PM

#

Ok back to basics.. Chapter 1: Setting up a project.

safe rose Oct 30, 2017, 5:15 PM

#

If you watch this video: https://www.youtube.com/watch?v=EM_HYqQdToE It should give you a better understanding of some fundamentals.

To answer your original question

plush yew Oct 30, 2017, 5:15 PM

i got 45 minutes of slepp

wtf

lol

plush yew Oct 30, 2017, 5:15 PM

and im about to die

that sucks

plush yew Oct 30, 2017, 5:16 PM

#

I spent ALL night working on starfighters

and after 2 years

safe rose Oct 30, 2017, 5:16 PM

#

get some coffee or something

plush yew Oct 30, 2017, 5:16 PM

#

I finally figured out how to do ship sway

#

nah

#

at school rn

safe rose Oct 30, 2017, 5:16 PM

#

@wild ivy Anyway, so if we take it from left to right

#

If checks to see if there is a valid reference of AI CON ref on Tick

wild ivy Oct 30, 2017, 5:16 PM

#

I mean i know variables quite well, as i used to webdev

safe rose Oct 30, 2017, 5:17 PM

#

Whenever this actually gets permission to go live

plush yew Oct 30, 2017, 5:17 PM

#

i know it sounds really simple but damn idk why i got stuck on it

wild ivy Oct 30, 2017, 5:17 PM

#

I dont even know what a tick is..

plush yew Oct 30, 2017, 5:17 PM

#

I think it was because I was using spring arms for the longest time

#

even tick

#

its a node

#

if you right click in the bp

#

type event tick

#

there

safe rose Oct 30, 2017, 5:18 PM

#

If there is a valid reference (i.e. Not Null), it will call this damn super expensive node; GetALlActorsOfClass, which returns an array of every single instance of the class it's set up to look for

wild ivy Oct 30, 2017, 5:18 PM

#

I would consider myself a good english speaker, yet do i still not know the exact translation of node

plush yew Oct 30, 2017, 5:18 PM

#

a fucking uh

#

you know

safe rose Oct 30, 2017, 5:18 PM

#

If it is null

plush yew Oct 30, 2017, 5:18 PM

#

the uh

wild ivy Oct 30, 2017, 5:18 PM

#

So its like collecting all the apple out of a fruit bowl?

#

Apples*

safe rose Oct 30, 2017, 5:18 PM

#

It will cast to the AI_CON class, using the Owner Actor incoming reference

plush yew Oct 30, 2017, 5:18 PM

#

@safe rose explain nodes

safe rose Oct 30, 2017, 5:19 PM

#

Which I can't remember where that comes from

#

I am not going to explain nodes

plush yew Oct 30, 2017, 5:19 PM

#

ITS the box things in bp

#

right?

#

or is that the wrong name

safe rose Oct 30, 2017, 5:19 PM

#

I am going over what is going on

plush yew Oct 30, 2017, 5:19 PM

#

oh

wild ivy Oct 30, 2017, 5:19 PM

#

Guess i get it

plush yew Oct 30, 2017, 5:19 PM

#

whatever

safe rose Oct 30, 2017, 5:19 PM

#

Regardless, we're at GAAOC node now

wild harbor Oct 30, 2017, 5:19 PM

#

Sorry to break in, but out of curiosity, how many ticks/sec are there in UE4, generally?

plush yew Oct 30, 2017, 5:19 PM

#

Oh hes working on AI

wild ivy Oct 30, 2017, 5:19 PM

#

GAAOC?

safe rose Oct 30, 2017, 5:20 PM

#

Immediately after we set My Location with is of Vector type

plush yew Oct 30, 2017, 5:20 PM

#

@wild harbor I think its 30

wild harbor Oct 30, 2017, 5:20 PM

#

OK, thank you!

safe rose Oct 30, 2017, 5:20 PM

#

That location is being set by the AI CON ref's host body

#

So, it's looking at the physical representation of the AI, the pawn, and getting that actor's location

#

setting it to My Location

#

Right after that

#

We do another expensive operation MultiSphereTrace For Objects

#

Remember this shit is all on tick

#

Anyway

wild ivy Oct 30, 2017, 5:21 PM

#

So its looking at where the actor is right now and hands it to the AI so he knows where im at and can follow me?

plush yew Oct 30, 2017, 5:21 PM

#

@safe rose actually I need some help, I am having collision cape physics issues where there is no collision for capes whatsoever

safe rose Oct 30, 2017, 5:21 PM

#

The trace start from the AI's host body

plush yew Oct 30, 2017, 5:22 PM

#

like it shows in editor that the collision is there

safe rose Oct 30, 2017, 5:22 PM

#

And ends 15 units above the Host

plush yew Oct 30, 2017, 5:22 PM

#

but it doesnt seem to work

safe rose Oct 30, 2017, 5:22 PM

#

then expands 1500 units in radius

wild ivy Oct 30, 2017, 5:22 PM

#

The radius of what?

safe rose Oct 30, 2017, 5:22 PM

#

So basically, there's this big sphere hovering around this damn AI on tick

#

But, it's only looking for the Desired Object Types

wild ivy Oct 30, 2017, 5:22 PM

#

Is it like a radar radius?

safe rose Oct 30, 2017, 5:22 PM

#

That's in that Green array

#

Hmm, sort of, yes, in this case

#

You can call it a radar, sure

#

And it's only looking for "desired object types"

wild ivy Oct 30, 2017, 5:23 PM

#

And the desired object types are players?

safe rose Oct 30, 2017, 5:23 PM

#

Which are collision settings

#

no

plush yew Oct 30, 2017, 5:23 PM

#

for capes

safe rose Oct 30, 2017, 5:23 PM

#

Collision Object Types

plush yew Oct 30, 2017, 5:23 PM

#

cape physics

safe rose Oct 30, 2017, 5:23 PM

#

anyway

plush yew Oct 30, 2017, 5:23 PM

#

the new inengine SHIT

safe rose Oct 30, 2017, 5:23 PM

#

It ignores all AI

#

in this search

#

Since it plugs in the damn GAAOC array into it

#

Anyway, next

#

Right after that "radar"

wild ivy Oct 30, 2017, 5:24 PM

#

So if there would be 100 zombies and 1 human, it would tell them to ignore each other and hunt the human down?

safe rose Oct 30, 2017, 5:24 PM

#

A ForEachLoopWithBreak (but break is never used...why) occurs

#

It will grab everything that sucker hits and figure out what type of actor it is

#

Every actor should potentiall be a "target"

#

Since it was distinguishing it in the object types

#

But, now we doing a LineTraceBy Channel

#

To see if the AI can see the Actor

#

MyLocation = Ai

#

Hmm

#

Lastly

#

If the AI can see it, it will set that target to the Blackboard target to follow

#

Which will do a whole bunch of shit in the rest of the BT

#

If it can't see the actor, it will make target to follow null, making it probably just stop.

plush yew Oct 30, 2017, 5:27 PM

#

I feel like

safe rose Oct 30, 2017, 5:27 PM

#

All that shit

plush yew Oct 30, 2017, 5:27 PM

#

Ive seen that before

safe rose Oct 30, 2017, 5:27 PM

#

happens on tick
