#

say even a couple thousand

#

for 100% i just go random float in range between 1-100 and then see if its less than or equal to accuracy

#

and i get a hit or not

#

any ideas?

tired cypress Mar 29, 2021, 10:25 PM

#

Yeah you could use Random Float in Range

#

But I'm not certain what you are going for after you acquire the random

halcyon grove Mar 29, 2021, 10:27 PM

#

i got it i just made the max of the float in range defender's evasion

tired cypress Mar 29, 2021, 10:27 PM

#

There ya go

halcyon grove Mar 29, 2021, 10:27 PM

#

and then check if accuracy is higher than the random number

#

if your accuracy is higher than the evasion you'll hit

#

its not perfect

#

but actually I think it will scale well

#

because the numbers can be whatever I want and it will be good enough 🙂

#

this like the 3rd time I'm doing this damage tree to tweak it better and I had brain poop

obtuse herald Mar 29, 2021, 10:32 PM

#

You could have 2 Random floats in range, one with min 1 and max 'accuracy' and the other with min 1 and max 'evasion'. Then you compare the 2 random outputs and the one which is higher wins.

halcyon grove Mar 29, 2021, 10:34 PM

#

i like that because of more variation

#

though I'll probably set a value of like 50 as the minimum in the accuracy

#

so we're not shooting in the dark xD

#

tweak and see how it "feels"

#

thanks

Is there a way to get performance overhead? Currently I'm using EventTick and comparing that to the target framerate, but in the cases of a locked frame rate, it seems like there isn't a way too see the remaining frame time.

in command console, type stat unit

and then look at the game time

also it's based on the paddle's local axis.

franman, you can use input axis

proven mason Mar 29, 2021, 11:27 PM

and add movement requires the object to be a default pawn.

not sure if add timeline can help

you can use a delay node and self loop

proven mason Mar 29, 2021, 11:30 PM

#

also I want the paddle to hit a wall and not go pass through it

#

anyways I have to think of ways of being creative

#

I'm not brainstorming hard enough.

snow harness Mar 29, 2021, 11:32 PM

static charm noneutrality, there might be a way but not sture

These are the specific blueprints. Output is essentially just a multiplier based on a curve. The Time of that curve is the Delta Seconds relative to target frame rate. At the beginning there, if Delta is higher it updates exactly, if lower it interpolates.
That Instances multiplier affects a global particle dealio.
Though any frame rate cap means it can't go over 1.
Not a big deal, but it would be cool to overclock the particles or resolution if I can detect the headroom is there.
I'll keep looking online otherwise.

Lol. Electric Nodes plugin doing the heavy lifting.

static charm Mar 29, 2021, 11:35 PM

you can boost particles/resoultion until you get less frames

then reduce to get back to target frames

basically a mini/short benchmark

what's the method for spawning a second player, but not doing split screen? For the menu part of some local split screen play, I'd like the players to each share the same menu while they do their avatar setup for gameplay and then on switching to the level for the actual gameplay go into split screen. But creating a player seems to auto-engage split screen.

i could of sworn i saw some plugin or something for free related to split screen just recently

#

I'm doing some digging i was getting a lot of noise with people asking how to enable split screen and then a lot of vague hand waving suggestions for disabling it. I think I'll have to do it in C++. there used to be a node in blueprint but it doesn't seem to exist any more.

#

but.. creating the new player still made my "menu" start over

and just draw it twice on the same screen

#

    Settings->bUseSplitscreen = isSplitScreenEnabled;``` this takes care of it..but yeah, when I use the "create new player" node in blueprint it seems to start a new player from scratch.

it's working for me on 4.26.1 Source Build! (the "go to cpp definition from blueprint" feature)

if you're using the precompiled build from the Epic Launcher, then you must move the contents of the UE_4.2x where the engine is installed to D:\Build\++UE4\Sync
you will need to create a D: drive where you can put it if you don't have one already

If you're using the source-compiled version, the feature seems to have broken in v4.26.0 but on v4.26.1 the feature is working. Strangely, there's no mention of it in the hotfix release notes.

so you wanna have a Branch there.. where if the value is higher than 180 you want to clamp it to be between 180 and 359

when its less than 180

obtuse herald Yeah, create a struct with all variables you want, like that:

And then create a DataTable with your struct and populate it with some data

trim matrix Mar 30, 2021, 4:11 PM

I dont get it. sorry ;/

#

I've got my Struct set up, and have it as a variable on my class

#

How do I now access that information within another blueprint?

#

I have a char that shoots a projectile. I have a spawner that spawns 2 boids. The projectile has a code that on overlap makes an impulse to the component the boid actor has. Now only one of them reacts to the impulse.

#

I want them both to react

#

picture is from the projectile bp

hollow cape Mar 30, 2021, 4:15 PM

show the code above. You are doing 1 compare, but you said there are 2 potential actors that need to react.... therein lies your issue @trim matrix

trim matrix Mar 30, 2021, 4:16 PM

there is just begin play and get actor from class and it sets that to boid reference

obtuse herald Mar 30, 2021, 4:17 PM

#

trim matrix I've got my Struct set up, and have it as a variable on my class

A struct is only a holder of variables (something like a folder i guess). So only having a struct wont solve your problem.
I'm assuming you're using these classes only to save data right? If so create a DataTable with that struct.

trim matrix Mar 30, 2021, 4:17 PM

i can get that print string working easily when hitting those both

I want that same logic to work here

Wait, are you using an Object or are you using Actors?

The Variable needs to be the Type: 'Your Actor'
Or you cast the variable to 'Your Actor' in runtime

Object, parent of actor

obtuse herald Mar 30, 2021, 4:38 PM

Note that Objects don't have World Context (Can't spawn in Actors, can't create Widgets, don't have a Transform etc.)

trim matrix Mar 30, 2021, 4:39 PM

Yep, I don't need them to exist in the world or tick, just have variables and functions

obtuse herald Mar 30, 2021, 4:39 PM

trim matrix Object, parent of actor

Let's say you have a new class called 'MyObject' with object as parent

#

In that object you have a variable called 'MyStruct'

obtuse herald Mar 30, 2021, 4:41 PM

#

obtuse herald In that object you have a variable called 'MyStruct'

And you have an actor called 'MyActor'. You want to reference the Object in there

trim matrix Mar 30, 2021, 4:41 PM

#

yep

obtuse herald Mar 30, 2021, 4:41 PM

#

To do that, you need to create a variable in 'MyActor'. Let's call this variable 'MyObjectReference'.

#

Now you have 2 Options:

#

Option 1: You set the variable type to:

and then you can access 'MyStruct' like that:

Option 2: You set the variable type to:

then you can access 'MyStruct' like that:

Thanks 🙂

Hello. How can I change variable category for multiple variables at the same time?

faint pasture Mar 30, 2021, 6:26 PM

the whole point of parameter collections is that they are global, but you don't want them to be global in this case, you want them to be separate per instance

#

I'll see you don't need to set it on tick, just set it with a timeline when they die

#

Er, set the radius with the timeline. You camln set your material up to only need a location when the dissolve is triggered as well. Or just use object location in the material.

brittle reef Mar 30, 2021, 6:31 PM

for the radius im using the a timline, will give a try on the location

without parameter collections

faint pasture Mar 30, 2021, 6:33 PM

Yeah parameter collection is explicitly used for global parameters, which is the opposite of what you want in this case.

where

right, then you need to store that doors open position

then on BeginPlay if door is open, just set it to its open relative position

how you get that from your save system, 🤷 but if the property is marked SaveGame, and you save that actor in the SaveGame, then it should be whatever value it is at the time the game is saved

Make your timeline go from 0 to 1, use that to make the door rotation line up with however you want it to be. So maybe door yeah equals 90 - 90 * timeline Alpha or whatever. Whatever gets it to work

#

You could just hard code the values in the timeline but something like this is a little bit more extensible, you just change your math for a different type of door instead of having to redo the timeline

summer bolt Not sure if I phrased something wrong sorry if I did

Here's what I did when I need multiple buttons...
Create a widget that contains a button and set it up how you want it to look.
In that widget, give it a variable of some kind to uniquely identify itself, and perhaps another variable for the "type" of button it is. Expose these variables on spawn.
Create an event dispatcher in the widget that passes through the identifying variables.

Have your main widget that contains the button loop through and create the buttons you require and place them in where you need them. When creating them, you feed in the IDs and types that you require. Then you bind your widget to the event dispatcher on each of the buttons, and on the event that is called, you will receive the identifying variables, from there you can create the logic for what should happen.

any help? 🙂

@royal zealot I would recommend setting breakpoints when that logic is called when you don't expect/want it to, and use the Call Stack to look at where it's coming from

royal zealot Mar 31, 2021, 12:03 AM

#

@sleek pecan ty ... thing is ... this all happens in editor ... no gameplay events whatsoever

#

it's just literally, the child actor component resets all variables of the child actors

sleek pecan Mar 31, 2021, 12:06 AM

#

Well, I would say you can move everything to Begin Play instead of having it in the constructor

#

or you might see if breakpoints activate while in the Editor in the Constructor, which they might. I don't know

royal zealot Mar 31, 2021, 12:09 AM

#

the idea is for it to work in the editor only... all the randomizing and settings changes ... it's a "tool" to build up the level, so to speak. after its set and done it should remain the same. hopefully I'm making sense with the explanation 😅

sleek pecan Mar 31, 2021, 12:09 AM

#

Well, you could wrap "randomize color" into its own custom event and make it usable in editor

#

then you'll have a little button you can click from within the editor

#

and once you have a color you like you can just let it alone

royal zealot Mar 31, 2021, 12:10 AM

#

yep ... the BP actor that is the "basic" component does indeed have a couple of editor evens

#

and it works perfectly fine

#

the problem is, once I add these "element BPs" as child actors to the "parent" actor, this parent actor keeps resetting the children at every interaction

it would be real cheap and crappy

I'm reading the documentation now. the word "PC" doesn't exist in the page, but all the appearances of 'console' refer to console commands

Hi, I heard that dynamic resolution is not possible on PC because it conflicts with distance fields? but this seems like an unlikely reason. So what's the real reason?

#

so the built in dynamic res seems its possible but not supported

obsidian meteor Mar 31, 2021, 12:56 AM

#

I'm reading this too. I have playtested a built version with it on

never saw dynamic resolution (that I noticed) and did get hitches (presumably unrelated)

so you have to edit engine code to get dyna res?

i didn't fully read the forum post, but dynamic res is suppose to adjust when the frame rate is suffering

so if your frame rate is fine, then dynamic res is not going to kick in

#

like i said its a cheap method

#

not really useful for your purposes, but it is useful to auto adjust graphic settings

#

#

i was gonna make this for auto graphic settings/benchmark thingy

#

but this is the concept

#

map range would be changed out for more dynamic logic

#

and the delay node, could be adjusted

#

and this could also be Nativized to c++

#

actually testing it, it needs logic to stop adjusting once its sort of tuned in

#

lmao

#

but the concept works

Anyone know if UE4 registers controllers that are "asleep"? I'm doing a setup screen for local multiplayer and expecting it to be used in big picture mode on a TV which would likely include wireless controllers. For avatar select, after they select the number of players a screen comes up with 2-4 panels on it that allows each player with their own controller to set up their avatar. When that page comes up, the code has to set the focus for each user to their own panel. I'm just wondering what would happen if a controller was asleep when this page came up and then woken up by the user pushing a button. Would it still set the focus properly and simply wait for the controller to respond?

TFW you are trying to make a custom UI navigation, because the native one have features that break your setup (such as the hardcoded Tab button overriding whatever action is assigned to the same button).
But I'm unsure that my approach to do that is entirely correct. Looks too messy. Any tips?

Anyone that can help me? I thought i solved the bug by making a second branch where i put in the return value from the linetacebychannel in. But i still get this bug

tranquil tundra Mar 31, 2021, 7:40 AM

#

that return value tells if there was a valid hit
if you continue from the false of the branch the hit will be invalid (or at least undetermined)
Just clear the link from that false branch

Is it possible to use multiple graphs but have each one of they depend on beginplay? Having everything in a single graph is very messy but I need beginplay in the other graphs in order to refactor a bit.

rapid robin Mar 31, 2021, 10:53 AM

#

Hey @eager peak , yes you can. Create a key binding for an action in your project. Call it 'Proceed' or something. Then in your logic, rightclick and find Event Proceed. Plug that into your logic instead of where the delay went in.

#

Hey @trim matrix , yes you can. On the left hand side of your blueprint you'll see the + in the Graphs section. Your new graph will also have an Event BeginPlay https://prnt.sc/110oz47

Hey @eager peak you could try something like this using some logic gates:

if you are lucky you'll find an autosave in your projects autosave folder of the affected bp

so you could overwrite your current broken one with the autosave

but like usual when doing something like this, a full backup of your project directory is recommended before

in case it makes things worse, you can go back to the backup

Cool assignment! Does the base game exist already or are you starting from scratch? Either way I'd start with the basics if I were you, then figure out some little challenges in a test level. By the time you've done that you'll have a better idea for what works and what you'll want and the level will start coming together as you progress.

I'm pretty much starting from scratch. I am able to follow along tutorials but I still dont understand the blueprinting. I've added a stamina system as well as moving platforms, doors, and simple things like that. The ai is not advanced. They will chase you if youre in sight and thats it.

rapid robin Mar 31, 2021, 1:54 PM

#

Alright, sounds like a good start. Maybe you could have some light and dark areas, and the dudes won't spot you if you're in a dark area. But if you're in a light area AND you're spotted by a dude for [x] seconds, then they'll chase you.

rapid robin Mar 31, 2021, 2:11 PM

#

@desert idol you could try making a blueprint with a spotlight in it and a trigger volume. So if the player is inside the volume they know they are in a light area (coz you'll set a boolean when you enter/exit it). If a badman 'spots' you, they can then do a quick check to see if you are in the light or not. If you aren't in the light, then they ignore you. If you are in the light then they'll go into chase mode. You can then add the timing thing in later if needed.

#

To clarify you'd then drag a bunch of these spotlight blueprints into your map. Good luck!

Hi, probably a dumb question

but if I'm using a ForEachLoopWithBreak

Does the completed execute fire if I break it?

Yes

desert idol Mar 31, 2021, 2:26 PM

Oooh that makes sense. Much appreciation!

Break will just have the foreach skip iterating any further, otherwise it behaves the same

languid lion Mar 31, 2021, 2:29 PM

One more question, what happens if an array is empty and I run a ForEachLoopWithBreak?

earnest tangle Mar 31, 2021, 2:29 PM

Same as with a regular foreach, it just immediately goes to completed

languid lion Mar 31, 2021, 2:30 PM

Huh?

#

Oh, you mean array index if you try to access it from completed?

languid lion Mar 31, 2021, 2:32 PM

#

Like when I try to find an item, and it's not found

obtuse herald Mar 31, 2021, 2:32 PM

#

languid lion Will array index give me a -1 or do I need to track it myself?

It wont fire the LoopBody as far as i know

languid lion Mar 31, 2021, 2:32 PM

#

and if I were to remove an array entry during a ForEachLoop, would the next entry now get skipped?

earnest tangle Mar 31, 2021, 2:32 PM

#

Yeah, the stuff you have in the body will never run with empty arrays

#

Removing stuff from the array during looping can lead to confusing results depending on what you're removing from it, if you remove the current item, it likely will skip the next one yes, because the next one becomes the current one, and then it will go forward for the next iteration

#

So if you need to iterate an array and remove from the array, make a copy of it and either iterate the copy, or remove from the copy

obtuse herald Mar 31, 2021, 2:34 PM

#

frozen spear Mar 31, 2021, 2:35 PM

Thanks everyone

Yeah, I myself use length -1

frozen spear Mar 31, 2021, 2:39 PM

#

I just can't wrap my head around when I update the code to use last index why it breaks this person's asset

earnest tangle Mar 31, 2021, 2:40 PM

#

Yeah I mean assuming it returns the same as length - 1, it seems like it should work

frozen spear Mar 31, 2021, 2:40 PM

#

It will return whatever the index is of the last valid entry in the array.

earnest tangle Mar 31, 2021, 2:42 PM

#

hard to say then, would have to look at the specific code in question I guess 🤔

#

but at least it sounds like it shouldn't break things

        return ArrayHelper.Num() - 1;
    }

    return INDEX_NONE;
}

languid lion Mar 31, 2021, 2:44 PM

#

last index -1 would be one value lower than get length -1, no?

earnest tangle Mar 31, 2021, 2:44 PM

#

It looks like it literally returns length - 1 lol

languid lion Mar 31, 2021, 2:44 PM

#

so it's length -2

#

when you do that

that's pretty interesting ^ ^

earnest tangle Mar 31, 2021, 2:57 PM

wait, when you simulate does it kinda rotate the whole body to the side and go down awkwardly?

#

Or is it constantly flipping/rolling around on the ground

#

ahhhh you're using convex hulls for physics

#

I had major issues with that

#

what I did is have a second phys asset for the skeletal mesh, and just before simulating physics, I switch the physics asset to a simple capsule physics asset

tawdry surge Mar 31, 2021, 3:11 PM

#

yeah he rolls on the ground and flies off.

hollow cape Mar 31, 2021, 3:11 PM

also make sure there's nothing with collision attached to the mesh (weapons, etc), and it's not colliding with the capsule

tawdry surge Mar 31, 2021, 3:12 PM

#

no, it's just a base mannequin. So the shape of his collision has to be simple capsule.. wonder why that is

hollow cape Mar 31, 2021, 3:13 PM

I believe the convex hulls are causing self-collision or something. I tweaked a bunch to make it work and just decided on switching physics assets directly before simulating physics.

frozen spear Mar 31, 2021, 3:19 PM

#

Yeah its complex math, i sent you a pm cause i dont want to name and shame..it a great asset but just a certain part does some array magic that if you change any of it you need to just rewrite the whole function

tawdry surge Mar 31, 2021, 3:20 PM

#

it's not really any better with the capsules.. I don't think it was colliding with it's self. cause it's collision reactions were good he's just not following the scrips. falls and gets blown away by magic wind

agile hinge I'm making a multiplayer game, should I put my inputs (ex: events for stuff like...

If your players are going to be controlling more than one class of pawn and those pawns may have different movement controls (think like a humanoid vs a car) then pawn is the place to put controls that are unique to the specific pawn. If you have inheritance set up, then perhaps you'd have a parent class of all pawns that your player may control and if so, that's where you would want to put any common controls that are shared between them, and if not, then in the player controller but then you'd have to feed the input into the controlled pawn. I've also been using the player controller for any input events for UI and the like.

Is the best way to toggle UI in a thirdperson game, so "UI only mode" then override OnKeyDown function on the focused UI, so that it can enable the toggle off press of the key?

#

I'm not getting really consistent results with it. Not sure if its a focus problem but it seems clunky

#

so this set up, as an example won't work because UI only mode locks the keyboard from inputing.

Then in the main widget when i want that particular button to show up, I actually create the widget instead and bind an event to the event dispatcher within the button. The extra arrays and map there are just for my own systems as I do some sorting later.

#

When I want to add the buttons to the layout I just loop through the relevant array and add them to a vertical box.

#

The event that the bind sets off will contain the data about the button that was pressed, allowing me to pass the data from the button to whatever i need it to do.

dawn gazelle Ok, so here I've created a widget that is specifically just a button... I handle...

so this is a secondry widget

dawn gazelle Mar 31, 2021, 7:31 PM

#

Sorry can't do that and it'd be far more confusing as there's a bunch I'm not showing that's not relevant.
Step 1: Create a widget BP that contains only a button and the label for said button. Add "exposed on spawn" variables used to identify and label the button. Create an event dispatcher in the button's widget that feeds through the identifying values.

Step 2: In your "main widget" where you'd want these dynamic buttons to exist, you create them by a loop or by whatever logic you want to use, but you use the Create Widget node. When you specify the button's widget class, you'll see the expose on spawn variables - you feed in the values that the button should have, again, you define where the data comes from, whether it's a table or an array of values, that's up to you and the logic you need to use. Upon creation they can be directly added to a vertical box or any other widget component that exists on your "main widget". Using the reference from the creation of the button, also create a bind to the event dispatcher within the button.

Step 3: The event that is created from the bind is where you continue with your logic for when the button is pressed, and using the data that is passed from the button in the event dispatcher, you can determine what to do next.

summer bolt Mar 31, 2021, 7:35 PM

dawn gazelle Mar 31, 2021, 7:35 PM

#

summer bolt Mar 31, 2021, 7:36 PM

#

but what variables

dawn gazelle Mar 31, 2021, 7:38 PM

#

That's up to you. However you wish to identify them or whatever values you need to pass through to label or otherwise customize the button widget. So in my case...

These are all my exposed variables.

#

and you can see them when creating the widget:

#

I'm using an enumerator for button type that mainly drives it.

#

So depending on the button type, it'll do something different, but then IDs are used to pass additional information through (like Mission1 is different from Mission2, but I can use "MissionStart" button type to indicate I have a mission to start, and I can have two buttons that are "MissionStart" buttons, both that can start a mission, but one is for Mission1 the other Mission2)

dawn gazelle Mar 31, 2021, 7:44 PM

We can still work this out. What do you not understand?

#

What I'm trying to show you is a way of dynamically creating multiple buttons that you don't have to necessarily create an event for each button press, which is sort of what you were asking for but with on commit events if I recall correctly.

#

In order to do something like this though, you still need some way of identifying which button was pressed or which text box was committed.

#

summer bolt 👍 alright i get that but the rest of it is confusin me

Here's an example of a very basic setup.
I have an array of name variables named "Button Names".

I can loop through the button names, create a button for each of the names, add the button that's being created to a vertical box, and bind to the event dispatcher in each button. I then get an event in my "main" widget that you're seeing here where I can control what happens when I click the button.

#

The ID is passed to the button when it is created, and the button when clicked, passes the ID back throguh the event dispatcher, allowing me to determine which button is pressed.

summer bolt Mar 31, 2021, 8:09 PM

#

so ima copy this just to get the hang of how it works

dawn gazelle Mar 31, 2021, 8:13 PM

#

The button widget itself is very simple. Just updating the name on the button on construct, and making the button press call its event dispatcher and sending back the values that were passed in on creation.

#

(i have a function there for the update button text, but I think you know the settext node 😉 )

Yes, you need to create some identifying variables within the button. In the example I gave you, you can get away with just a "Name" type variable and call it "ID". Set it to "Expose on Spawn" and "Instance Editable"

I'm trying to do a hexagonal progress bar, and a friend who uses unity suggested trying a radial mask

earnest tangle Mar 31, 2021, 8:52 PM

#

fallen glade is this better ?

There might be some better solution to this, but something that could work is if you find the last spline point that's inside the sphere, and then the next spline point that's no longer inside it. You could then plot points using a binary search algo between those two points, until you're happy with the result

#

ie. something like this where the circles are the points you find, then you plot in their midpoint at 1, then since 1 is inside the sphere, you plot at midpoint between 1 and the outer point, you get 2, which is then outside the radius, so you plot between 1 and 2 for the next one

#

I'd imagine there could be some mathy way of determining it too but I don't know enough math for that lol

Essentially I have a main menu UI widget bp that creates the other tabs of my UI and sets their visibility to be hidden. Whenever the user clicks a button to go to one of those tabs it sets the main menu UI to be hidden and the corresponding UI to be visible now. My issue is that when I want to hit a back button to go to the previous tab, I don't know how to reference the different widgets created within my main menu UI widget. I set them all in variables of user widget object references currently in my main menu UI widget.

burnt trench Apr 1, 2021, 5:04 AM

#

I found a bug in Unreal 4.26 which causes it to crash everytime

#

Not sure if its intended to crash or not

#

I have a Map variable with a enum and a struct as key and values

#

I populate it in the blueprint

#

and then change the struct (add or remove a value)

#

and try to recompile

#

it crashes

#

is that normal and should that happen?

spark steppe Apr 1, 2021, 5:08 AM

#

well, i guess no crash is intended

leaden dock Apr 1, 2021, 5:08 AM

#

i know how to crash the engine too 😄 disable realtime, enable show fps, then disable realtime override, then enable realtime and then disable show fps, and then it crashes 😄

#

@burnt trench is the struct that is the map key custom ?

#

like is it a fvector or so or a struct you made yourself?

#

oh you used an enum as the key, lol sorry, but thats really weird

#

usually the key needs to have some type of hash function, at least in unity

#

so e.g. a struct with 3 floats generates a hash based on those floats and then the map uses the hash as the key

#

and it looks through the hashes

#

so every struct that's a key needs a hash function

#

to provide a unique hash per value set

burnt trench Apr 1, 2021, 5:12 AM

#

Crashing Unreal is a breeze. Just make something null in code without handling it. Works every time haha

#

Map makes the keys unique

#

does that answer the hash part?

leaden dock Apr 1, 2021, 5:13 AM

#

a map only checks the hashes and sees if it exists already

#

it cant magically just hash something

burnt trench Apr 1, 2021, 5:14 AM

#

did I mention this is in blueprint

leaden dock Apr 1, 2021, 5:14 AM

#

just saying, enums dont have functions, so probably an enum cant be used as a key

#

you could make a struct holding an enum and using it as the key though (maybe, didnt try)

#

Well this is the variable I have

#

that's insane. 20 major engine versions and they didn't fix this?

leaden dock Apr 1, 2021, 5:19 AM

#

hm in c++ it'd probably be better to store a pointer to the struct so the map doesn't change, only the struct itself

#

changing the struct would need to change the whole map

#

well just a guess

spark steppe Apr 1, 2021, 5:26 AM

#

it's a luck game, and depends on where/how you access the struct

#

i think its either related to the break struct node or if you have a node where the struct is used and set that pin to split output

Is it possible to dynamically set a variable inside a function?

weak gulch Apr 1, 2021, 6:31 PM

Hi everyone, I have a math question I'm trying to figure out. I have a system in place to score the player's drifting that works great. But I want to save a snapshot of their amount, when they stop drifting, to a total score pool. And then I want to be able to add to that pool when they drift again. Current drifting score is calculated on tick as I need to be able to get player movement and angle to calculate the score properly.

The problem: I can't seem to figure out how to save the score properly. I need to be able to keep adding to the total pool and right now all I can do is track them.

Picture is how I have it setup, with the red circle being where the math I'm looking for probably goes.

azure knot Apr 1, 2021, 6:45 PM

@tropic storm could you just set the health variable on beginplay? I can't think of the name of the node off the top of my head but there is probably a float random in range node that lets you set a min and max and returns a random number within that range and you could just set the health float variable with that return.

keen goblet Apr 1, 2021, 8:05 PM

@weak gulch So you know the score the player is getting from currently drifting, and you have a var that you want to store the total score the player has gotten from all drifts.

Seems like all you have to do is TotalDriftScore += CurrentDriftScore when the player stops drifting, so that the CurrentDriftScore you use is the total score from the drift that just ended

Is there a way to get average frametime from the context of a BPL? I'm trying to expose some stats to Remote Control and the only solutions I'm finding are all dependent on hacky solutions using deltatime and an actor or widget, and I'd rather avoid that sort of solution. Plus, I'm not even sure that would play nice with RC.

tight schooner Apr 1, 2021, 9:43 PM

#

BPL = function/macro library? I don't think those can hold nonlocal variables and you need that to have a running average. You could put the function there but some object would have to hold a variable that your library function works on, so maybe put it in Game Mode or some other manager class. I can't comment on Remote Control unfortunately...

I can see its outputting values though.What Im trying to do is create a mouse pointer inside a bounding box.

OK found the problem mouse axis is a tick event causing the values to be set to 0 when using the controller.

Hi guys! anyone have any idea on how to destroy an Uobject from Blueprints?
i know that it's by removing the references and waiting for gc, but is there any way to force this? maybe some node to remove all references to some Uobject? go into all the references is just too much of a trouble in this case

twilit heath Apr 2, 2021, 12:57 AM

#

from c++ you'd call MarkPendingKill

#

not sure if thats exposed

#

also having too many hard references to an object to track them all doesn't sound like the best plan

#

best to assemble clear, clean object graph

#

where you know which object is responsible for managing the lifetimes of other objects

runic parrot Apr 2, 2021, 1:13 AM

runic parrot Apr 2, 2021, 1:31 AM

#

do you change visibility at any point?

neon sorrel Apr 2, 2021, 1:32 AM

#

Yep, did some debugging and got the visibility and it returns visible when toggled, sets the mouse as its supposed to, but the widget itself is invisible still.

runic parrot Apr 2, 2021, 1:34 AM

#

would have to look at your blueprint to check further, maybe you are missing some visibility change you made by some condition

#

also, i'm having some troubles with Uobjects interacting with others.
The short version is My Ubojects class have "Hp" and every X seconds, they reach to others Uobjects and transfer 1 hp from the other to themself.

The problem is they are firing at the same time and one extracts 1 hp, adds it to him and the other one tries to extract from that same Uobject that is not updated still, so both get 1 hp from the same Uboject, but the later one only losses 1 hp.

Could anyone point me a general probable cause of packaged game freezing upon open level?

I have a game which has two levels - menu level and game level (this one is quite big, with some level streaming involved). Game 100% times works on launching and loading game level from menu. But after playing some time, when i open in-game menus and try to return to main menu (basically open level node call) the game freezes infinitely very often - it looks like it depends on pc, some people have it more often. The logs just end on calling open level node and thats it - no error, nothing.

Anyone could point me any direction i should investigate? I am stuck on this without hope at the moment.

#

Maybe i should do a cleanup before calling open level node? Destroy npcs in world, unload some streaming levels? Maybe the game has issues with amount of content loaded when i try to switch levels?

Problem with .uasset files is that they have to match UE4 versions

Hiho i try to create an Inventory System for non Stackable items it is sill working but the Stacks will not work...

I have 5 Bushes to grind 5x Blueberry the first 3 Bushes will give me 1 Berry and Bush 4+5 will not give me Berrys (its all the same Bushes).

My stack maximum stacksize is 4 for testing it.
The 3 Berrys are in the Inventory but not stacked

#

If im changing the Berry to not stackable, i have all 5 Berrys in the inventory...

#

I think the mistake is in the "Addto Stack" function but i will not get any errors or warnings. Also the logic should be ok, i think. Maybe someone know the mistake or can help me to fix it?

#

Im also stuggeling by the way to create the stacking BP at first i have splited allparameters like that

sonic pine Apr 2, 2021, 10:28 AM

ok thats what i mean, you can cast the hud/main widget to your parent class char and every child should earn this hud. The differnet settings like Healer = 300 Health 500 mana and warrior = 500 Health 300 mana yan be changed in the child BP but the HUD to show the Health bar, inventory and so on is earned by the parentclass
