This is how I have it set up in my level blueprint

and then use Switch node in the sound cue
to plug in the random int from the blueprint
tribal kraken
This seems a bit off
When I print to string, the number that comes out has no correlation to the song that's playing
Did I do this bit wrong?
static charm
yeah the random Int might need to be Set once before pluggin into the Paramter and String
oh yeah

I'm having an issue where my shot gun projectiles seem to go through enemies if they're too close. My shotgun is set up like this: Gun spawns shotgun shell which immediately spawns a numbers of projectiles based on the weapons data and then destroys itself (the shell) while the projectiles fly off. The shell is spawned at the tip of the gun and the individuals projectiles are spawned on top of the shell, right at the end of the gun. I have a scatter formula that gives a spread. It works fine, and if the enemy is at least a meter away I've noticed no issues, but I have noticed that if the enemy is almost right on top of me, it doesn't hit them. This is a bit of an arcadey shooter, so it doesn't need to be super realistic or anything, but I'd like to make sure these projectiles hit enemies right in front, is there another check I should use for that?
static charm
well you need to debug it a little and verify if the bullets are spawning inside, or infront of, or to the side of the enemy, etc
if you haven't seen
in the spawn node settings, the collision handling option
which could be affecting how/where the bullets are spawned if the enemy is in the spawn location

I've been trying to use variables to rotate a skeletal mesh smoothly (finterp, anim blueprint, etc). Seems that none of the methods I've found work in the newer version
I'm probably missing something tiny, but it seems that one can't use floats on a rotation node for a skeletal mesh component, so therefore no finterp
tribal kraken
@static charm one more thing, how would I make sure the random int doesn't repeat the same number in a row? I just had one song play, and then it played again.
static charm
well im not sure you need to be adding audio component after each song finishes
but regardless, uh

I'm having an issue where no matter what I do calling Set Show mouse cursor false won't hide the mouse
i set the input mode to game and UI
but when i use the gamepad, i want the mouse to hide
static charm
alright i made super lazy and dumb not twice dulplicate sound player
otherwise to make it better it would just use an array
Well the mouse is hidden by default
so you have something thats unhidding the mouse
flint sedge
I'm literally just calling set show mouse cursor true or false
I check the hide on capture box on the set input mode game and ui
i event just made a flip flop that toggles the show/hide with M
doesn't work half the time
i also do "lock always" on the mouse options in set input mode
i'm setting widget focus, would that do it?
so with my flip flop here is what i'm seeing
stuck hedge
@static charm The projectiles are set to always spawn and ignore collision. They should be spawning at the end of the gun always. Maybe if they spawn inside the enemy, they'll leave the enemy before they "hit"?
flint sedge
i toggle mouse cursor TRUE, it doesn't show till i move it
i toggle mouse cursor FALSE, it doesn't' hide till i move it
static charm
show ur code because it works for me
Crossmr, yeah i don't think collision hits are two sided like that
so if it starts inside there probably won't be an exit hit
as a work around you can make an overlap area, like some small collision shape at the tip of the gun, that applies the bullet damage directly to whatever it overlaps
stuck hedge
hm...so on begin play maybe i should get overlapping actors and check that.
static charm
yeah
flint sedge
static charm
what about your other code
oh
yeah i see now
you need to focus the viewport or to widget when doing this
flint sedge
stuck hedge
@static charm The only issue I run into there is a lack of hit data. I have ragdoll deaths in my game, so I need information like the impact point, etc. I'll have to generate that another way.
stuck hedge
actually maybe it's okay. Now that I look at it, I'm mainly only using the hit location for two things. Reporting the damage to AI and for finding the closest bone struck. Even if the point was inside the unit, it would still return the closest main bone (I only do impulses on major bones, not all of them)
flint sedge
thanks! I will try that.
the "set focus to game viewport" I'm not very familiar with
is that a full screen focus?

anyone know how to do weapon pickups where if you press a button it picks up the item?
I have this so far, it's incomplete but not sure how I can do it https://blueprintue.com/blueprint/v33ethg5/
static charm
have you looked at any tutorials yet?
lavish glade
yes they use different approach then what I already have set up
static charm
they would probably be called item interaction
there's a few ways to do item pickup by key press. you can use Overlaps or you can use Line trace to see where the player is looking at
lavish glade
no I just want it so if they are in the sphere and they press "E" then it picks it up. I've already done overlap and that works but I want a button to pick things up
Why does this not work? https://blueprintue.com/blueprint/__vkbmmh/
static charm
oh okay
in the blueprint settings
class defaults
then right side of screen
search for Auto Recieve input
set it to player
then the blueprint will accept inputs
lavish glade
where is class defaults?
static charm
top of blueprint graph screen
lavish glade
there is a lot of players
static charm
hmm
lavish glade
do I just try all of them?
lavish glade
oh player 0 worked
lavish glade
Thank you so much man 🙂
I had no idea class defaults even existed
ok but what if I want to do multiple pickups?
static charm
multiple in what way
like at same time
or just multiple types
like food, water, etc
either way you can just right click and duplicate the blueprint in the content browser and change what you want
or make a child class of it
etc
lavish glade
no it's not that
it's just when I have a different gun I want to pick up and in class defaults for auto receive input I set it to player 0 then none of them work, I only get to pick one
static charm
alright
click the Input Action node
and the settings on the right side of screen
turn off consume input
lavish glade
oh it works perfect now, again thanks a lot mate 👌
static charm
although if you have hundreds of pickups in a level, you may want to change how the code works
lavish glade
how can I get the gun to highlight when the player enters the pickup sphere?
static charm
probably just do a material effect
you can use Dynamic Material Instances to do that
or even just change the material
lavish glade
so is that in the sphere collision details panel?

Question please, how can I change my AI controller Class in the game?, I set it to different class but it does nothing and still return the normal AI class
@lavish glade On component begin enter?
Go for that event
on the sphere collision yes
static charm
Where did you set the class?
trim matrix
Inside the AI blueprint
static charm
is the AI already placed in level?
trim matrix
yes
static charm
sometimes the blueprint settings don't update to the level instances
there is a button to update
or just delete and replace it
in map
static charm
oh that
trim matrix
ye, when I print tick the Ai controller class, it's still default
static charm
if you want to change class during runtime?
or is that during construct?
during runtime you need to spawn AI controller and possess with that new controller
lavish glade
hey guys, like this? I have the target set to my gun, is that correct?
trim matrix
Isn't there a node to change Material?
static charm
yes changing material will be the easiest right now

@static charm thx for helping btw how can i spawn the AI?
there is Spawn AI from class but, i already have my AI spanwed
oh wait, i dont wan to spawn AI, i want to spawn controller

yup

how can i get it to posses my AI tho?

How can I get that material to glow?
trim matrix
show me your material
static charm
change the material to unlit and then put something in for the emissive
trim matrix
u want everything to glow?
lavish glade
I want the outside to glow
trim matrix
if u dont, you will need mask
lavish glade
ok what is easier
trim matrix
that's the easiest method to get glow on certain part
there is no other magic
my sword sheathe with glow
just need mask to specify the areas
lavish glade
ok I got my material to be unlit, now how do I make it glow?
I did emissive boost to 1000 but it's still black
trim matrix
i plug this into my emmisive
emmisive multiplier = intensity
Emmisive color = The Glow color
Alpha is the mask texture
this is very simple setup
If you dont have alpha texture then you can just plug the multiply onto the emmisive, but that would be an ugly gun imo
if this is for Item pickup, maybe you want to do Outline instead?
lavish glade
uhh
where do I find the blueprint, I forgot
oh nvm
ok so my material blueprint is big
I am very lost
lavish glade
nope
static charm
so
left side of material graph screen
some settings you see
one of them is shading model
change that to unlit
static charm
or
maybe it doesnt need to be
lol
guess i should read up on materials
anyways just drag what plugs into the base color
connect it to a multiply node
then either make the pin b of the mulitply node, some number like 10
or plug in a constant
and make it some number
lavish glade
Honestly that does the job 🙂 I made it look much more complicated then it should of been
thanks for the 3rd time

Hey peeps trying to find the quickest way to get references to anim instances that multiple characters in my level are using. Having some trouble. I thought Get All Actors with Tag would allow me to Get Mesh and then Get Anim Instance but I guess I can't without casting?

Hey guys, I've got a setup that I'm trying to do where you switch from a top down RTS style camera, and then at a later point possess a man with a whole different control set. They way I was hoping to have it work is from the RTS style camera you select the unit, hit a button from the presented widget screen and then it goes to change the playercontroller. The problem is although I could do possess and un possess it gets messy with the controller and such. What would the recommended way to change "controllers" and players in the middle of gameplay?
Just to clarify, I understanding switching possession of pawns, but am unsure how to switch the controls
indigo zenith
controls are on pawn
most of time
so u posseses human
u have human controls
u posses a vehicle
that has controls for vehicle
or make interface and use those events to drive functions that do controls
quite roughly
input wsad can be used for character and vehicle
sage marsh
oof, I didn't think about that. I did the RTS controls on the PlayerController instead of on the camera pawn, I will give that a shot
indigo zenith
when u posses a "pawn"
u can use wsad per "pawn"
so if its a vehicle it uses throttle input as W
but it has a different functionality for a character
trying to be clear as possible
didnt had any sleep
sage marsh
It's a mobile game so it's all touch drag input, but should be pretty easy to move. Thanks for that, I can't believe I didn't think of that -_-
Thanks @indigo zenith, huge help!

@snow halo get anim instance should be for all character based class i believe
you should be able to
snow halo
looking back at what my q was hehe
trim matrix
@snow halo
snow halo
right i know that works but
try Get all Actors with tag
because it only returns the base actor class you can't get mesh
since you can't get mesh, you can't get anim instance
trim matrix
are u only trying to return characters btw?
snow halo
hopefully i'm wrong somewhere here
ya ultimately I'm trying to get all instances of a specific anim instance that multiple characters in the level share
trim matrix
hmm i havent thought much about it but you are deffinitly right
u can always do casting
snow halo
i can't cast or dunno how because it's all different character bps
snow halo
unless i can cast to some generic character class
trim matrix
that will work for all across your bp that is based on character
snow halo
oh ya that will work. Do you like that approach or my workaround better? My workaround was to have one character bp (master) and every other character is a child. then I can use get all actors of class
all characters in level are children of BP Nancy pictured (it's a character bp)
snow halo
I need to grab variables from my custom c++ anim instance
trim matrix
what if the character have different anim instance?
snow halo
so i assume i have to cast to it
trim matrix
so u only want to store face anim instance and nothing else?
snow halo
ya totally
if the cast fails on some characters that's great since then it won't store them in the array
snow halo
i only want to store characters that use this specific custom anim instance
i'm creating a marketplace plugin to facial mocap multiple characters in a level
trim matrix
yep, casting it to that specific abp will work then
snow halo
so hopefully it makes sense what i'm tryin to do : )
trim matrix
👌
snow halo
i decided to cast to the specific anim instance and skip the abps all together
figure that's ok too
sorry i know my variables pictured say ABP
but the type is actually my custom anim instance
trim matrix
anything is good as long it works man 🙂
trim matrix
if u only want to store specific instance
snow halo
child character bps versus tags

then use your way

how could I get the angle between these vectors? #1 is fixed, #2 rotates on Y. the current solution either gives me positive values only (need to know if it's negative - vector 2 below vector 1) or the sign flips according to the pawn orientation
twilit heath
pull the length of cross product and then asin
that will work for +/- 90 degree range
but won't be able to tell the difference between 45 and 135 degrees
although if your angle is in +/-90 degree range, the dot product will be positive, negative otherwise

this got me really confused for a while. Apparently it is possible to have an actual blueprint graph of a parent open in a child? I've been noticing some other strange behaviour, like if you double click a function to open that graph, sometimes it will go to that graph tab, which is what I'd expect, but some times it will change the -current- tab to the function graph. So the same tab will go from say event graph to function graph. So as I work the blueprint I sometimes find myself having 5 event graph tabs open! wtf is going on, when did this happen?

Good morning ! wondering if i could ask for some help ... I have 3 problems i am fighting today with but would need some pointers maybe to get them solved 🙂
So i am using raytrace to fire a beam that then should trigger if hit by the right cube the laser on the next cube and so on .. Issue is when i try to have a visible and not visible switch on it it wont just not show up at all once hit .. while my source cube using the same code always fires for some reason .
So i am doing something like this
this is the issue i cant understand why its not firering even though its getting trigered .. Raytracing in this works pretty well though
this is the result
ignore the laser not alligned issue .. thats only because i had to alt tab out to show it 😛

@hard galleon that looks like you're using a single ParticleSystemsComponent and trying to make it render all 3 particle systems

hard galleon
well it works fine if spawm 100 source laser cubes
twilit heath
each cube should handle its own laser
hard galleon
only when i set the laser to relay cube ( same cube type basically just wont auto fire ) and trigger it trough the event it wont
twilit heath
when its hit
twilit heath
that code looks like you're configuring a particle system, then telling the hit actor that if it was hit, provided its a cube
hard galleon
Well what i am doing .. I have a cube .. I made a variable enum where you can set it what cube type it is . Each cube has its own instance of a particle system ( if i am understanding what i have done right ) XD . at the start i disable visibilty to all laser .. and then depending if its should fire (same as the raytrace ) it should enable it .. if i remove the disable laser thing the laser work .. just never despawn when they are not updating there position anymore when they shoudl

but since i dont disable them like now when everything breaks this would happen https://cdn.discordapp.com/attachments/579545686291251210/675522488435867668/unknown.png
and i know why this happens .. what i dont understand .. is why the relay cube is not firing the particle when it should :/
I have a terrible feeling that i sort of need to somehow to figure out how i can fire all rays first ... wait for that to finish and then enable or disable the particle visibility before the tick ends but after all rays are done doing there stuff
twilit heath
you did not show the relevant code/context
twilit heath
do you have separate particle system assets for different colors, or is it done by SetParameter?
hard galleon
is there an easy way to take screens of blueprints that show all of them but make themreadable too ?
color is a paramater that i can set on the fly
though i know why color mixing is not working
thats because its forgetting the other color between each triggering
need to fix that later .. one issue at the time 😛
so this is the entry point for my cubes
firing laser mechanics right now (part1)
part 2
ignore the mess still just prototyping this 😛
trim matrix
How can i get a rotation from component space to bone space?
hard galleon
when it comes to color mixing .. i have to redo some stuff and sort of build a temp memory so it can remember all the colors i am firing at it on each tick .. now that just resets after each time it gets hit anyway .. though i anyway have to build in that you cant loop the fire ( hiting a cube ) in a loop
twilit heath
first thing you do
is keep a reference to the cube you're hitting
and a SetHitCube function to set it
if your trace returns no actor hit, you set it to null, and you turn off the laser
if it hits a cube, you set it to that cube and turn it on
if the cubes aren't moveable, but can only be rotated, which i suspect is the idea here
hard galleon
you can move most of them is the idea
twilit heath
ok, then trace on tick is fine, otherwise you'd need to trace only when the rotation changes
when you hit a cube
you call a function on it
and it stashes the reference to the cube hitting it in an array
important part: if your SetHitCube function is setting the currently hit cube to null, it needs to notify the cube it was hitting that it no longer does before nulling the reference
hard galleon
question .. ( pretty new to UE blueprints etc ) is there a way i can assign an ID automatically / get it to each cube without user input ?
actually this is the third day only of me playing around XD
twilit heath
each time your array of cubes hitting a cube changes
you pull out their colors (which are basically vectors4)
sum them up
and divide by the number of elements in the array
and set that as vector param on its particle system
unreal does it with names already, they are unique
so in a single sentence: keep a reference to the cube you're currently hitting, as well as reference to any cubes currently hitting this one up to date, use setter functions for those references to notify other cubes of the relevant changes and adjust your laser visibility/color
hard galleon
thanks .. i guess i do this first then before i worrie about the particle not firing issue .. maybe it fixes it self by then
Though! i have another issue
XD

well, i have to go buy groceries for lunch, but maybe someone else answers it

guessing thats where the problem is. Do i use something else than this actor location and rotation node?
edit: Plugging in does work but creates a node between the two called RotationFromXVector. That didnt happen in the tutorial

I'd guess you want one location along spline and one rotation along spline. Then plug the corresponding one into new location and new rotation.

If I discover this issue I'll be sure to share it 😃
vocal barn
I think it's because you are only setting value to a float variable
try putting a add movement input
nvm it's the sprint which isn't working ?
if so then try setting your max walk speed at normal rate when your release your input
worn kernel
i tried that even put it to something as crazy as 5000 to see if im not seeing the diffrence but nothing chage
changes
wispy star
is the inputaction run bound to a key?
worn kernel
yeah left shift
wispy star
is it triggering?
wispy star
well, the only reason i can imagine is that your character not using referenced Character Movement to walk
worn kernel
is there any way to find out if am
vocal barn
is your script on a pawn bp or a player controller bp?
if it's on the pawn you should find the compenent window at your left, you simply drag the character movement component into your script table
worn kernel
player blueprint
vocal barn
if you have a player controller you have to cast to your pawn and get the character movement reference
so you could put a get controlled pawn => cast to "the name of your pawn" => get character movement
vocal barn
your first person character is your pawn?
vocal barn
@worn kernel maybe you forgot to put your walk speed at max walk speed
you did change max walk speed but not your actual speed
i think that's the problem
worn kernel
how do i put my walk speed on max
vocal barn
on your movement script, do you use the max walk speed variable or another variable?
worn kernel
just walk speed
vocal barn
i see
instead of changing max walk speed on your run script just change walk speed
dont forget to put back the normal value on release or else you will be stuck at your running speed
worn kernel
i cant change walk speed only max speed
worn kernel
no
worn kernel
its default
vocal barn
can you put a screenshot of your movement script?
worn kernel
vocal barn
not this one, the one you use to walk please
worn kernel
its inherited
vocal barn
what do you mean by that
worn kernel
OOOH
twilit heath
@worn kernel if you used GetPlayerCharacter instead of GetPlayerPawn, you could lose the casts there
vocal barn
did you find your problem?
worn kernel
yeah another script was used to stop the character in motion when a animation was called and that was stopping it from being called
so every time i changed iot with the button it would detect that i wasent in animation and change it back to default
vocal barn
that's good to hear!
quaint portal
i made a head bob with a camera shake. but it's not that realistic so i tried adding a camera anim to it in the "anim shake" but it doesn't change the result at all. anyone knows how to do this?
celest oar
UMG channel is dead, does any know how to scale a umg image to fit the size of the screen?
worn kernel
just one more queston anyone know how to lock the camera so it dosent rotate and move the player model
celest oar
can u be more specific?
you want the camera to always stay in one place and never move
like a 2d sidescroller?
worn kernel
like a animation is playing and i cant get the camera locked in one place so it looks wird ill show it
celest oar
an animation like a cutscene?
celest oar
well in that case the easiest way to do that would be to disable input and then enable it at the end
worn kernel
alright
celest oar
or you can make a cutscene in the sequencer
and blend your camera to the sequencer camera when it begins
but thats a bit more work
worn kernel
yeah that works but i want the player to be able to press e to get out of the ship
lavish glade
hey guys can any1 explain why this happens https://www.youtube.com/watch?v=8veeEb5dD_M ? Here are the blueprints for the pickups https://blueprintue.com/blueprint/gydxx2cl/ and https://blueprintue.com/blueprint/pg3xekcm/ . Sometimes the character can pickup the gun from a mile away
ye sorry about taking all that space
celest oar
@worn kernel you could make a bool var and only let the input work when its false
and when u do that cutscene jsut set it to true and at the end false
odd ember
@lavish glade you shouldn't be doing logic for pickups in your weapons
lavish glade
then what should I be doing
odd ember
the weapons should just tell the player that they are there and what they are
the player should have the logic for making/picking the weapons up
odd ember
what I said
lavish glade
so the inputaction interact?
odd ember
the way you do it ordinarily is by letting the pickup class tell the player what's going on when the player overlaps it
so the pickup sends itself to the player
the player then acts on that pickup
lavish glade
yes and why does that not work
odd ember
that's not what you're doing
lavish glade
the player can only interact when he overlaps the circle
odd ember
you're having your pickup do the logic for the player
the player doesn't know what it can interact with
lavish glade
so do it in the character blueprint?
odd ember
yes
or ideally in the player controller blueprint but you're new so player blueprint is fine
lavish glade
I have no idea how I would set it up
when I look it up on youtube I always see people do it on the pickup
odd ember
yeah because people on youtube aren't developers, they're mostly noobs
it's the blind leading the blind
silver bolt
hi y'all, anyone familiar with splines?
I'm generating a wee road https://www.youtube.com/watch?v=jeXbL6Md4Bc
how do I generate tangents? I currently have them at 0
This is how I'm generating now https://blueprintue.com/blueprint/ufym1j2z/
lavish glade
@odd ember but how come my M4A1 works perfectly fine but not the other gun (the one inside the building)
odd ember
probably because you screwed up some value so it's constantly interacting
anyway it's stuff like this that makes the logic on pick approach pretty shit to work with
if you had the logic on the player you wouldn't be subject to these issues
light glen
i did something pretty dumb and deleted a c++ class that i had a child blueprint using, can i reparent without restoring the old code?
odd ember
you should be able to @light glen
lavish glade
I think you right cuz I just duplicated my M4A1 pickup and I think the bug is gone, not sure yet cuz the bug kinda hard to replicate sometimes
light glen
PIE crashes when i try to edit, can't see any way under the right click options
odd ember
what do you mean PIE? are you trying to reparent real time?
light glen
play in editor, did it get a new name?
odd ember
yeah why are you playing when trying to reparent?
light glen
i can't open these now without crashing out
odd ember
restore the old code then
odd ember
I did a similar thing but I could reparent fine
surreal peak
If you lost them then congrats on your first reminder that you should always use Source Control.
odd ember
to be fair it was a component class and not actor
surreal peak
Then put it back in place
Well or that if you have nothing in them anyway
You should still setup Source Control if you haven't already
odd ember
@surreal peak any chance you know how the third person template takes a RMB to activate the camera movement? it's nowhere in the project settings as a modifier key
surreal peak
Weird. Source Control should allow you to just roll back to the last working state
odd ember
you could try creating a dummy bp class with the same name and inheritance
surreal peak
@odd ember Sorry?
odd ember
when you use the third person template input, the camera doesn't move until RMB is held down
however this is not explained through the project settings anywhere
surreal peak
It's probably in the pawn
odd ember
I see, I'll take a look
lavish glade
nope the bug is not fixed
odd ember
again it's probably the fact that interacting is never set to false
or some shit like that
anyway you're going to keep having this problem until you move logic to your player
quaint portal
hello. i have a head bob animation but when i walk it plays once normally, once again but weaker, then a third time really weak and then it doesn't do the animation until i unpress and press walk button again
using a camera anim in a camera shake class
lavish glade
@odd ember could it be possible that the zombies are creating the overlap? https://blueprintue.com/blueprint/pg3xekcm/
odd ember
@lavish glade probably
lavish glade
I believe it is, so do I do cast to thirdpersoncharacter?
lavish glade
I get this
odd ember
why are you doing it on component
I mean it doesn't take 2 secs to hook it up correctly
lavish glade
I don't even know what it does so I just connect it lmao
odd ember
well then good luck
lavish glade
yes the zombies are the issue
fathom portal
I'm drawing a blank, what is the term for the node that lets clicking work in game but also in your UI?
fathom portal
Yes! Man I've been searching through my code trying to remember what it was called
Thanks @odd ember
Hey friends, I'm not sure what I did, but all of a sudden my left click no longer triggers the left click event in my pawn, what should I investigate first?
olive cloud
is input enabled?
olive cloud
yes
fathom portal
I added it, no change. It's weird, I wasn't even working on anything input related, it just all of a sudden decided not to work
So uhh
I removed the "enable input" that I literally just added and now it works again
What in the world
olive cloud
wacky
timber gull
Look if it's not your left click event which sometimes doesn't fire because of some error
fathom portal
Not sure, it didn't show any errors after playing in the editor
timber gull
it doesn't need to show an error to have one : exemple, your left click fire a bullet and sometimes the bullet is invisible, the game doesn't tell you any error but for you it is.
trim matrix
Hello. Could anybody help me? I'm new in Unreal and I'm playing with interactions. According to some tutorials I saw it's the best idea to do it through Interface. So I created it and now I'm trying to do something if key button is pressed and held. So I created something like this (in the picture below), but through the interface it works only once. When I stop holding a button and press it again it's not working anymore. How so? Thank you and if you have better solution for this I'll be glad to learn it.
fathom portal
From initial glance, it seems you should be hooking up the execution line to "play from start", no?
I'm no expert in interfaces tho
trim matrix
Yeah true. I forgot to change it when I wanted to make it clearer before I post it. But it doesn't matter much if it's in loop I think.
olive cloud
There isnt a way to get nearest point on spline is there?
elfin hazel
you should get some functions just by typing nearest.
Or keywords such as closest or near.
trim matrix
I found the problem. There's nothing with Interface, but I forgot I have a condition in child blueprint which called parent interface. Anyway thanks for help
worn kernel
ok so im trying to get a ai meter on my screen to test it but the text wont change even thought its affecting it so its not being displayed
its just 0
static charm
my guess is the issue is outside of that function
use print strings or breakpoints to see what is being called and/or not being called, see values, etc
example of using print string to debug stuff
worn kernel
im refrencing it
and i did print string but its not showing
the +1 at the top left is the string
static charm
okay and what is +1 telling you what is working?
static charm
okay did you check that the function is being called?
and then check the function is working correctly
sorry i showed wrong picture too
that will print the float's value itself from within the function
im going to guess you haven't set the fear monster reference. although you should be getting an Error popup due to none referenced
worn kernel
yeah its just zero how do i cast it so i can refrence it
static charm
you can either save the monster reference to some location like game state, and then get the reference from game state inside the widget. or you can Get Actor of Class to get the reference
or if the monster can get the widget reference, it can pass it's own reference to the widget
tepid fossil
Hi all 👋 If you have a blueprint that contains a static mesh at root, and you scale that static mesh down to 10% of its size in the blueprint, when you spawn an instance of the blueprint (whose static mesh you edited and scaled), should that instance be scaled down in the scene? For me, it looks the scale remains the same no matter how I set the transform in the static mesh - I must be missing something?
static charm
oh yeah if you use the spawn node
it has scale settings
this is the root scale of the blueprint
so if you want to keep the static mesh scale as in the blueprint you need to get the default scale you set
or make the static mesh not root, and it will keep the scale when spawned as scale 1.0
static charm
yup
tepid fossil
I actually replaced the Root node with the StaticMesh, and I don't see any component called Root when I try to add component - is there specific component type that I can use which will have a transform (and then I can nest the current tree under it)? BTW, thanks very much for your help!
static charm
scene
(or just make a new blueprint)
but scene is an empty component that will work
tepid fossil
If I set that scale to 10.0, or .1, when I spawn the items in the scene, they are still back to 1.0
tepid fossil
Got it
static charm
(and this only happens because when using Spawn node it asks for the scale you want to set the blueprint/root, which then overrides the default blueprint/root scale)
tepid fossil
It actually makes a lot of sense, now that I see it done this way - thanks a ton for your help 🙂
static charm
there is a way around it, for example you can Get Class Defaults and then plug that scale in
but then it just clutters up the graph unless you have a lot of defaults you need to get
analog ice
Is there a way to disable my character from being animated in the Character Blueprint Viewport? It makes it very difficult to attach components with his idle animation playing.
analog ice
Thank you!
I don't suppose there would be something similar to put him into a T-Pose for easier attaching components?
static charm
change the blueprint animation mode
or select an animation
click the skeletal mesh in the blueprint and you will see the options on right side of screen
analog ice
Great 🙂 I overlooked that because some of the other dropdown options, it kept playing, but Use Animation Asset stopped it. Thank you!

maybe the physics of the bullets are not activated (i.e set simulate physics) ?

opal pendant
@static charm is there a way to spawn an object with the input class as a variable?
for some reason it never works when I use the Weapon class variable
static charm
its multiplayer
no idea
otherwise should work
id remove stuff that have any effect on the spawned weapon and test the basic function of just spawning the weapon
and just to be clear you did actually set the weapon class there too?
and not just make the variable weapon
opal pendant
yes it's set to the Firearm class, which is the parent of all of my weapon classes
and the object is also a Firearm Object
I think I figured it out, might be an issue with the server not knowing I'm selecting the weapon in my weapon select menu
late gorge
hi, can someone help me debug why this is happening?
this is the controller, it's the standard third person controller with print (the values in the video)
for some reason side to side isn't updating the rotation :\
haughty ember
@late gorge Sounds like you want to orient your rotation to movement; there's a property in the movement component for that
late gorge
no, i dont want my character to follow the movement
haughty ember
Also, next time use a site like gfycat.com for the video (people can see the video in here rather than download it)
late gorge
i want it to be independant of the camera
haughty ember
What rotation are you talking about then?
late gorge
they both use identical code to drive them
anim bp and mesh are the same
the movement input section:
clean project:
custom project:
input axis have been renamed and some prints for debugging, other than that i don't see any differences and am not aware of any other code that would be relevant
i've checked that nothing else is attached to these input axis events
terse harness
I'm struggling with adding widget components to actors. I adjust the widget so it's where i want it relative to the actor in the actor viewport but when running the game the location changes. can anyone link to a tutorial on doing this properly?
stiff tendon
@terse harness It's parented to the actor, so if actor moves, the widget will move in 3D space as well. Also if you changes its 'RelativeLocation' in blueprint, make sure you didn't use 'AddRelativeLocation' because that might continuously add a translation and make the widget drift forever. Not sure that's your issue though
@late gorge You're probably using different 'CharacterMovement' settings? I mainly thinking about the 'OrientToMovement' setting
Because indeed inputs doesn't seem to be the issue here
stiff tendon
It's a component inherited from the 'Character' class
you should see it in the list of components along with the mesh, capsule, arrow
click on it and you'll be able access its settings
late gorge
yeah that fixed it but its not behaving same as just a clean controller
it has a lag to it
instead of being instant
terse harness
@stiff tendon ah ok so scaling/moveing the actor in the editor might be moving the widget disproportionately?
late gorge
~~https://gfycat.com/glumunconsciousbunny~~ nevermind, that's exactly how the clean controller behaves
stiff tendon
@terse harness what do you mean the 'location changes' first of all? Is it just displayed at a location you do not expect it? Does it jumps once? Is it drifting/moving somehow?
terse harness
@stiff tendon nah it's static, it just appears too high+ to the right in the actual game
also im not moving the actor in the BP in anyway
also, in the actor viewport the widget is invisble from certain angles, not sure why
like i can only see it from far away
stiff tendon
@terse harness that's probably due to the widget's 'pivot'. You probably have to shift it by half its width and height because its displayed location will be its top-left corner
@terse harness Not sure about the visiblity issue. Probably the occlusion culling. If the widget is big enough that you should see it but the actor owning it isn't in view, it'll skip being rendered. I think.
terse harness
Ok thank you, I'll try adjusting the pivot
Ok yeah the problem was the widget's screen size was set to something weird, was messing up everything

stable arch
Hello, I've made PlayerGraphics.sav and i wanted to add shadow quality and more, does it matter if i use the same slot name for all the settings i will add or i need a different slot name?
late gorge
is there a way to access value/slider range programmatically or is that just UI fluff?
stable arch
@surreal peak @trim matrix so it doesn't matter if i have a save called PlayerGraphics?
surreal peak
UE4 handles graphic settings via the GameUserSettings
It has the functions and the object exposed to BPs
You use these for your graphic settings
And if you have access to c++ you'd also put more settings into it, such as audio
stable arch
ok so i can just switch to "GameUserSettings"? @surreal peak
for all?
example one of all bp's
surreal peak
You don't have to use SaveGameToSlot
You call ApplySettings on the GameUserSettings object
You also don't need to create a SaveGame for this
This is all handled by the GameUserSettings
It saves them in the GameUserSettings.ini
Which is also a better way of saving settings
Cause like this your users can edit them outside of the game, in case they set something that stops them from starting the game (e.g. wrong resolution)
surreal peak
?
surreal peak
Yeah but that's not desired
stable arch
it happened to get it stuck and never go back on
and i deleted the PlayerGraphics.sav file
surreal peak
You DON'T need a SaveGame for this stuff
surreal peak
Buddy, the SaveGame is wrong. The GameuserSettings handle this
You are basically doing the work twice.
twilit heath
end ending up with a binary format save that can't be manipulated via text editor
surreal peak
You can delete all of that
Just call "ApplySettings" on the "GetGameUserSettings" return value.
trim matrix
soo, is there a way to get a tsubclassof class object from blueprint?
surreal peak
I guess? What exactly do you want?
trim matrix
I have a data only class that holds a tsubclass of, and I just want to get its data from a blueprint
surreal peak
@stable arch You don't need to use any SaveGames for this. That's all I'm gonna say. I already gave you what you need.
trim matrix
I can't seem to see anything that is tsubclassof from get class defaults node, it seems to autohide them
surreal peak
TSubclassOf will just show up as a purple Class pin.
Limited to the Class and its ChildClasses that you specified
twilit heath
you got the EditDefaultsOnly/EditAnywhere on the members?
trim matrix
apparently I forgot BlueprintReadOnly on those, I thought EditDefaultsOnly would cover that, but I guess I was wrong
thanks for the tip, otherwise I probably would forget about it 😄

@stable arch might be easier for people if you tell who is "it" that was showing you the problem, and what is the actual "problem"
gusty shuttle
Anyone know how to stop the collision of a particle through a wall? I can stop the beam emitter but not the mesh emitter. Any quick tips will go a long way. I am also using the Actor Collision module on the blast wave but it seems to not be working right.
odd ember
@gusty shuttle make a hitscan trace first, the impact point is the end point of the emitter
sullen radish
left mouse click is not working in blueprint, it doesn't make any effect during gameplay ... someone knows why ?
i've noticed it has to be in the pawn blueprint. 😄 thanks
gusty shuttle
@odd ember I already do, the first green circle that works, but thats for a beam emitter, but inside that particle is a mesh emitter too, and that seems to not work for that. Unless I can GET that mesh emitter from the particle
sullen radish
it worked when i moved the everything into the pawn blueprint... don't really know why but it worked.
odd ember
@gusty shuttle I think it's a question of separation
you're trying to make one particle system do two things
you should separate that into two
gusty shuttle
Aye, I suppose. I might have to do just that. Though it feels a bit silly because one Particle system can house many emitters
surreal peak
Read all of that and you should understand why it works in some places and not others.
sullen radish
@surreal peak Thanks a lot.
odd ember
@gusty shuttle they can house many emitters because you can layer emitters on top of each other for different effects. but in terms of purpose, it's best to have those emitters be uniform in scope
just like with everything else in computers
sullen radish
@surreal peak i guess the problem was that i forgot to put the logic blueprint i built into the level 😅 ,, it was never there to receive input .. LOL

Hey, is there a way to bind a specific input device (the keyboard or a gamepad) to a specific player controller?
So the players can select which controller they can use to control their characters. I see that the engine assigns the controllers and keyboard automatically, but can't find any way to control that and change in runtime.

Idk, but just if you have Keyboard PC so don't make there Event of Gamepad

in code there is, not so sure about BP
cedar sparrow
I know i've asked this before, but im really struggling with how gamemode, gamestate, and levels fit into my game
for reference, im just trying to make the arkham horror LCG card game
each campaign has different effects, but they all follow the same gameplay rules
so im not sure where to put the rules for like drawing and resolving card effects
vs where to put the campaign specific rules
i know that each scenario would get its own level, but then is it the gamestate that holds the campaign info between scenarios? or is it the gamemode?
am i making any sense? lol
odd ember
the hierarchy goes
Game Instance -> Game Mode -> Player Controller/Game State
game instance you want to keep things that are important per game session and handle persistent data loading/saving
cedar sparrow
ah jeez i didnt even think of game instance. now i gotta read about that lol
cedar sparrow
ah ok
odd ember
keep in mind that in most cases Game Instance shouldn't hold logic beyond its scope of being a meta class that keeps the game session infrastructure running
cedar sparrow
hmm ok
cedar sparrow
hmm so it sounds like GameMode would hold all of the rules that apply to every campaign (round sequence, when to draw cards, etc)
odd ember
Game State is also mostly seen as a stand in for player controller seeing as in multiplayer you cannot replicate the player controller
cedar sparrow
but gamestate is cleared between levels?
odd ember
yes
cedar sparrow
so where do you store stuff that carries over between levels?
odd ember
game instance
cedar sparrow
ok
odd ember
sometimes controller/game state if necessary
cedar sparrow
got it
so for me
it sounds like each campaign gets it's own GameInstance
and all of the rules for playing go in the GameMode
odd ember
nope
there is one game instance per session
you could make your structure so that each campaign is a level
and then use game state to fuel each campaign
cedar sparrow
oh ok
yeah that makes more sense
thanks for the help
im gonna run with that for a few days and see where it gets me
odd ember
good luck

last jetty
Hey, can anyone explain why might a float keep resetting its value to 0.0 every time I reopen the project?
tropic tide
because it is not saved

But I have saved it

I save the blueprint and project each time
tropic tide
did you make save file?
last jetty
I did save the file. All other changes are retained except for the value of this one particular float.

maybe you forgot to connect something?

It's the default value of the float, so I don't think it should be being influenced by anything else
