It's the difference between asking for contact 0, and asking for all the contacts and then picking out just the first one and throwing away the rest.

how can I set a function that take a float or int , can I call it everytime I update the slider ? I forget how to do it

#

This worked nearly perfectly, but I think I want a SpringJoint, rather than a HingeJoint. It makes the object move in 3D rather than on a single axis. Thanks for the tip.

#

Now I'm deep in Spring Land, trying to figure out why this thing is CRAZY

#

The HingeJoint was a lot more stable, and tended to settle in the middle of the screen where the invisible grabber is. But the spring joint almost wants to remain constantly at motion.

Hello. When moving in a specific direction and checking distance between object position and destination position to snap, how to not fly over the object?

Theoretical example:

bool isMoving;
float speed = 10;
Vector3 finalPosition;

private void Update()
{
    if (!isMoving)
        return;

    Vector3 direction = GetDirectionToPosition(finalPosition);
    transform.position += direction * speed * Time.deltaTime;

    if (Vector3.Distance(transform.position, finalPosition) <= 0.1f)
    {
        transform.position = finalPosition;
        isMoving = false;
    }
}

In the example above we can fly over the destination if our fps is low without snapping. Can someone help me with a good approach here?

I never got any help on this

#

so I'm bumping it with some clarification

#

the reason the material's on a quad is because of the particles attached to it

#

its a prefab

#

so how can I orient it to face away from a surface it's on

and how would I do that

#

I'm 100% doing something wrong here but idk what it is

Hi, is there a way to avoid Dictionary or Hashset lookup with State machines?

It seems pointless in state machines where all transitions from one state to another are pre-defined. Technically no lookup is needed, each state already knows the other states it goes to before program runs.
But how would that work then? I want to avoid reference nightmare on Awake() but also avoid runtime lookup.

// processed by state controller, Dictionary/Hashset lookup
public int nextStateHashedValue() {
    if (...)
        return hashOtherState1;
    return this.hashedState;
    // in the Controller, myStates[this returned value]
}

// return the new state directly (requires pre existing reference?)
public State nextState() {
    if (...)
        return ??????; // state member variable that has to be assigned in Awake()?
    return this state, but the instance, somehow???;
}

I've seen people do like, a bunch of addTransition(stateToSwitchTo, Func<bool> condition) on Awake() but I prefer to write the state logic by hand. So I have this dilemma.

#

⭐ TLDR;

if (nextState != 0)
    currentState = myDictionaryOfStates[nextState];
// etc```

```State nextState = currentState.getNextState();
    if(nextState != currentState) // or some kind of integer comparison whatever etc.
        currentState = nextState; // NO DICTIONARY OR HASHSET LOOKUP

How to achieve 2nd behaviour where no lookup is needed? Without reference nightmare of instances in Awake?

oh nvm, my discord just didnt load properly while scrolling up 😄

you could probably do hundreds of thousands of lookups per frame without your fps dropping below 30

edgy sinew

#

at that point the editor is limiting your fps

With string lookup it was like 240-320. Int lookup, 380 consistent

If I'm making, say, 100 nearly-identical objects, with identical rigidbody and Box Collider settings - is there an easier way to do that than copy-pasting 100 prefabs? Say, if someone accidentally removed a rigidbody or collider component from one object, it'd be a pain in the butt to track it down.

Object Pooling allows you to have 100s of prefabs "ready to go" at anytime. Whenever one is needed, you simply "activate" it, rather than actual Instantiate and Destroy which are slow.

why does it not preview what

edgy sinew
polar acorn

#

cos it needed a quaternion thing

languid pagoda

So, if your surface normal is straight up, you'd have a direction vector of 0, 1, 0, which is going to give you a rotation of one degree about the Y axis

it goes to the right spot, texture and particles are just fucky

I had no idea that was bad practice

true pine
polar acorn
#

If you look at the prefab with the transform gizmo on, which arrow is pointing in the direction you want the bullet hole to be facing

#

Like, is it the front you want to see it from? The top? Depends on the orientation of your prefab

true pine
#

well the direction depends on the angle of the surface it's hitting

polar acorn
languid pagoda
edgy sinew
# true pine I had no idea that was bad practice

nah ur fine, yeah it's very expensive to Instantiate and Destroy at runtime
Object Pooling is kind of like, having all the Lego pieces ready from the start of the program. And you just turn them on or off as needed, never creating or destroying from a memory standpoint.

# true pine see I never knew these existed

So, you have some base "Equippable Thing" class... then you have a "Fireable" that is not only equippable, but also can be aimed & fired... a "Throwable" that can be thrown rather than fired... Etc

So when you go to equip a new item...
You're not equipping a firearm, or throwable
You're equipping EITHER of those things, and the computer will allow either to fill the slot

Then you just have different behaviour depending on what's equipped ...

This is called Polymorphism

I don't have very many issues or things to expand upon there

#

making it exist/work first

winged ridge
edgy sinew
#

If your Update function ends up looking like this... You're probably doing fine and you can build a whole game

void Update() {
    readInput();
    checkIfGrounded();
    calculateNextPosition();
    calculateNextRotation();
    moveToNextPosition();
    // etc
}

See how it's English? It's step by step? Someone who's not a developer could probably get the idea.

#

So when you revisit some part of the code, oh guess what, it's in freaking plain English what is happening

edgy sinew
# true pine making it exist/work first

I usually do "make it exist/work" or "find out if it's even possible to do this in this way", then "OK it's possible let's make it clean and easy to work with."

Can anyone speak to their experience either splitting out or combining functions? I have this Grabber class that allowsme to pick up items, and I want to add the ability to bring items closer or further from the camera using the scroll wheel. I could see us making two functions - one for bringing the item closer, and one for sending it further. Or we could make a single function that takes the Scroll Wheel value as a parameter, and then moves the object based on that parameter.

Any thoughts?

polar acorn
edgy sinew
#

Why do we need 2 functions? This can be done in Update() with SmoothDamp or however you like

odd remnant
#

Not quite. The Player Class manages the input from the scroll wheel. When the scroll wheel moves, it calls a function in the Grabber Class. Either one of two functions - decrease distance/increase distance, or a single function: ChangeObjectDistance.

#

And the distance that the object moves will be a variable that I'll tweak to make a smooth movement feel to it.

grand snow
#

thats worse 😆

nimble apex
#

lol

grand snow
#

probably fine when not done too much all the time

odd remnant
#

You're saying the scroll value alone would suffice?

grand snow
#

sorry talking about linq myself

odd remnant
#

Oh, haha

grand snow
edgy sinew
# odd remnant You're saying the scroll value alone would suffice? 
float epsilon = 0.08f; // Snapping distance
void Update() {
    if (Mathf.Abs(desiredItemPositionFromScrollWheel - currentItemPosition) > epsilon)
        currentItemPosition = Mathf.SmoothDamp(...) // or however u like
    else // Probably not great to assign this every frame, maybe check equality first too
        currentItemPosition = desiredItemPositionFromScrollWheel; // Snap to exact desired value
}
#

I'm curious if it can get more efficient than this, assuming the scroll wheel should be read every frame.

#

There's no need to overcomplicate. Doesn't matter where you call the functions (WHEN probably matters though), where the data is stored, how you read the input. Get access, and do what's needed. Or if nothing is needed, do nothing

Any news here? I wanna help but you haven't posted any code. And what you said wasn't relevant to the solution I posted - doesn't matter if you have delta scroll position or absolute scroll position, that code works fine.
And if you aren't using either of those, please educate us on how you get scroll wheel input.

Maybe use a Curve for smoothness. Something like, difference in position vs. max distance to move this frame perhaps. SmoothDamp is usually good enough but I use Curves cause they're fun.
Here's a simple ScriptableObject class so your Curves don't reset when you exit Play mode.


[CreateAssetMenu(fileName = "CurveAsset", menuName = "Scriptable Objects/CurveAsset")]
public class CurveAsset : ScriptableObject
{
    public AnimationCurve curve;
}```
Hope this helps. I didn't mean to be rude when I said it sounds like things are being overcomplicated.

Im using visual studio not vscode. So its an asp.netcore webapi player sends credentials to webapi and then gets a token back in return that is used to verify if authenticated. both the web api and the unity project rely on some POD classes, so I have a visual studio solution with the webapi and a "shared" dll that is referenced by both unity and the webapi. It is currently under development so when I build the shared dll it executes command in visual studio to copy the dll to the plugins folder in unity. Only problem is you cant just copy it in like that it fails every time unity is preventing it. So anytime I need to make changes to shared.dll i have to go into unity delete the existing one then copy the freshly built one from the output directory to the plugins folder. Its annoying and inefficient

edgy sinew
# odd remnant Lol, you didn't exactly answer the question I was asking, but you did propose so...

AFAIK the question you had was to use 1 function or 2 - the answer I gave was none at all and to just use variables (desiredPosition, currentPosition) with every-frame checking (if in the right state) as I wrote out (Events wouldn't save much FPS unless the scrolling won't be happening every frame when object equipped)

There's a great video from Toyful Games about Springs, that could be worth looking into as well. That's where I first saw this kind of "set the DesiredValue when needed and the per-frame code just handles it" But there can be issues with overshoot.

Yeah please give it a try "DesiredPosition" and "CurrentPosition", with the every-frame if (different < epsilon) that I wrote

# odd remnant Yeah, I'm mulling it over. I think the only way the player will do this is by sc...

The BOTTOM LINE is that you always have, some desired item position and some current "Item position based on scroll (& other factors)" right? So that system ONLY does that 1 thing

This is called Single Responsibility Principle. Where you get the inputs from, what extra modifiers and logic go on top of that, that's all cool. But the system, is the system

You shouldn't have to change the actual system, to add more or different functionality

rocky canyon
#

but yea, good example..
lots of things in a game can be affected by different mechanics
a + b is a really nice mindset to have handy for alot of things
and its clean b/c u don't have to toggle off that functionallity.. just set it to 0 to ignore it..
a + 0 = a

#

Moar Modular

edgy sinew
#

In other words, when an item is equipped, the game always brings the ItemCurrentPosition towards the ItemDesiredPosition, smoothly.
How those are calculated, how much change happens each frame, what kind of controller the user uses, is all separate and unrelated to the main item-relocating system itself.

rocky canyon

u can do the same thing with multipliers.. but using 1 instead of 0

edgy sinew

Are events really that good or is Unity just checking if the event was fired every frame 🥹

i actually need to rewrite almost all my code to use them more often

# edgy sinew The BOTTOM LINE is that you **always** have, some desired item position and some...

And I'm not. I'd been using current and target position in my update function.

Though I'm not sure how this:


if (Mathf.Abs(Vector3.Distance(targetPosition, grabberRigidbody.position)) > epsilon)
    grabberRigidbody.position = Vector3.SmoothDamp(grabberRigidbody.position, targetPosition, ref grabberSmoothVelocity, 0.1f);
else
    grabberRigidbody.position = targetPosition; // Snap to exact desired value```

would be more performant than this:

```Vector3 targetPosition = playerCamera.transform.position + playerCamera.transform.forward * grabbedObjectDistanceFromCamera;
grabberRigidbody.position = Vector3.SmoothDamp(grabberRigidbody.position, targetPosition, ref grabberSmoothVelocity, 0.1f);```

thats when i'd possibly unsubscribe from my InputHandlers()

edgy sinew
#

I found it takes too long to resolve, always. Especially if you modify params in anyway like the smoothTime

#

The 0.08f is just the closeness to trigger an exact-value snap

#

SmoothDamp does that internally but it's not customizable i think

#

I just use curves and epsilon or clamp with a minimumVelocity to ensure resolve

rocky canyon
#

Curve junkie over here lol

odd remnant
# edgy sinew That's fine, if you're OK with how SmoothDamp behaves

I'm about halfway to loving it. I'm noticing two strange things - when I rotate the camera and scroll the scroll wheel at the same time - the object doesn't get closer to the camera until it stops rotating - this screams "async" issue to me. And the second is that as I rotate the camera - even moderately-slow, the object is kinda jerky.

odd remnant
edgy sinew
rocky canyon
#

u could seperate the two..
zoom/pan w/ an outter gameobject wrapper..

#

and then rotate an inner

edgy sinew
#

Maybe the calculation is wrong, I didn't look deeply into it

odd remnant
edgy sinew
#

Yeah definitely. do you have Interpolate on?

#

Is the Rigidbody kinematic?

odd remnant
#

Yes, it is.

rocky canyon
#

golden rule with FixedUpdate() is don't have Input in there..

odd remnant
#

Interpolate though, I'm not sure.

edgy sinew
#

Physics is a whole topic

odd remnant
rocky canyon
#

yea don't poll for input in fixed

odd remnant
#

I don't.

rocky canyon
#

cool cool..

odd remnant
#

It's only performing the smooth damp movement to the target position.

#

But it seems like the camera movement and scroll wheel somehow aren't happening at the same time - and it's weird because when the camera is rotating SLOWLY, it's fine.

edgy sinew
#

I don't think you can just move Rigidbody like that

#

Maybe try Physics.SyncTransforms() after you directly set a Rigidbody transform.

#

I think with Kinematic Rigidbody, MovePosition and MoveRotation don't screw up the interpolation?

#

there's rules to it, I forget the exact details.

midnight plover
#

MovePosition work for both, but as we had earlier a case, its bad for like restricting player movement with walls or what not. Its more to like push things away while your character is moving

odd remnant
#

Hang on, new info - the above wasn't true. Whenever the camera (or maybe the mouse) moves, the scroll doesn't work - but when there's no mouse movement, the scroll "catches up" to the new location.

Physics.SyncTransforms() didn't fix it.

edgy sinew
#

You can also turn interpolate off, on a kinematic RB, and just set position directly in Update.

#

I'd recommend getting this working without Rigidbody first. Just a regular GameObject.

rocky canyon
#

i recommend that dozens of times..
i always tell people if things aren't going ur way or ur having an excessively hard time with something
break it into pieces.. and work on a single piece in isolation... all by itself.. nothing to go wrong but the code ur working on..
once u get it working and u add more and more to it you'll easily being able to pinpoint where the code goes rogue and stops working..

#

much easier than working out a full mechanic w/ lots of moving pieces all at the same time..
heck theres even times when i'll have something not work.. and i get it fixed just to realize i broke the thing that was already working..

that happens less often too when i go at it bite by bite byte by byte 🤪

I had the same issue when "picking up" a Rigidbody. (SetParent to Player's hand) - so basic huh? Unity tries to control the Rigidbody when Interpolatation is enabled. So i just had to disable that on pickup.

itemToPickUp.GetComponent<Rigidbody>().interpolation = RigidbodyInterpolation.None;```

FYI it's not great to `GetComponent<>()` at runtime. I'll be getting those references on Awake() eventually in a "ItemThatCanBePickedUp" script to avoid this.
#

Idk if that's helpful, it all depends what exactly you're doing with the Rigidbody.

glad shore
#

How can i tell if a animation has played(from a script) in an animator

rocky canyon
#

i mean. its not as bad as running a Get in Update() or soemthing 😄

#

atleast in urs is only when u pickup or drop something

odd remnant
#

Which happens in another class's Update class.

rocky canyon
#

well thats also a no-no
updating the same thing from fixed and update at the same time especially a Transform

odd remnant
#

Could that be the root of the issue? targetPosition is updated in the FixedUpdate step, and dependent on a variable whose value is changed in the Update step.

#

The transform itself is only updated in FixedUpdate.

edgy sinew
#

Yeah 100%

rocky canyon
#

oh, well if its depending on a value updated in Update() its possible its changing quite drastically compared to the last value Fixed() thought it was

edgy sinew
#

You should change the "desired position" in Update, but only ever move the object in FixedUpdate, towards that Vector3 desiredPosition

#

Unless you were to go the other route and remove Interpolation. Then you don't need FixedUpdate until you re-enable Interpolation

odd remnant
#

Interpolation is the SmoothDamp, right?

edgy sinew
#

First thing I'd try is to remove that last line of FixedUpdate, replace with MovePosition

#

No - Interpolation is a Rigidbody setting that tells Unity to approximate the position of a Rigidbody in Update. Why? Because FixedUpdate is not synchronized with Update

odd remnant
edgy sinew
#

An object moving at 50 FPS (fixed) will not look good if the game is at 60 FPS.

#

MovePosition has a speed to it too. But if your desiredPosition is smoothly calculated, you can just have infinity max speed.

In the list of calls it goes Update -> fixed update -> late update as per Unity documentation

eternal needle

i dont know where you got that info, but that list of calls is just wrong

polar acorn
#

They're separate loops. One of them is going to occur before or after the other simply due to the fact that Unity is multi-threaded, but the timings have nothing to do with each other. You shouldn't think about it being "before late update" because it isn't. It's called when it needs to be

edgy sinew

Unity themselves state physics should be calculated in fixed update

That’s correct. The “order things happen” we were clarifying

theres a reason its called the physics loop in the link i sent

edgy sinew
#

PhysX looks good Ngl. Real good

winged ridge
#

Right so if update is based on your frame rate calculation, then anything not tied to physics should be in it. Hence pre physics as I said, arguably could be post physics but then just use late update

edgy sinew

You can switch Physics to run on Update time too! lol

#

For non deterministic funk?

fast relic
edgy sinew

🐴

fast relic
#

some (visual) frames its called before physics, some after, some multiple times, some physics is called multiple times (because your fps is lower than the physics tick rate)

update is all over the place while fixed update is, well, fixed - it runs consistently (by default) 50 times a second

That is the only place it’s mentioned on that page, though. So you’d have to go to Physics API or FixedUpdate to learn more yeah

eternal needle

they show it this way because thats the execution order. as digiholic said, its not multithreaded so it technically does run in some order

winged ridge
eternal needle

you still arent understanding, what i wrote isnt the same at all compared to your original point (where the order was wrong still)

edgy sinew
#

There is no order. Physics runs on its own time lol

rocky canyon
#

u can see in the flow-chart how they loop back on themselves

image.png
winged ridge
#

And they take frame rate because a frame rate is a base calculation between 1 second and another, they are varied based on other factors

edgy sinew
#

“yield WaitForFixedUpdate” see that at the bottom?

#

Do you know what yield does

eternal needle
#

i dont think I can explain it anymore clear that fixed update does not use your frame rate

#

maybe reread some of the messages above because there isnt much value in us repeating the same points over and over

edgy sinew

yield is cool … framerate saver

This is getting nowhere on either side

Dead Cells needs some of that Ngl

It’s getting to, you learning about yield hopefully ??

#

You think we’re playing here bro? You wanna know more or not

winged ridge
#

That loop does not state it goes back on itself it says when 1 process is finished it can go back and restart

polar acorn
ivory bobcat
#

If you have a frame skip of say, 2 seconds.. the fix update method would be called many extra times to offset the frame skip whereas update would only occur once

rocky canyon
#

if everything was consecutive you'd not have any of those loops returning back to a certain block

#

it'd only be at the very bottom

eternal needle
#

it really feels like they're trying to teach us here by saying "This is getting nowhere on either side". It's really hard to teach someone who won't accept that something is wrong

rocky canyon
#

i think theres some ego/argumentative nature here

edgy sinew
#

Always a little but, we’re here to learn more not say things are one way whilst being clueless

polar acorn
#

How it specifically works is that whenever it comes time to run FixedUpdate, it checks the clock time to see how much time has passed since the last one. If at least your FixedDeltaTime has passed, it runs FixedUpdate, then increments the internal physics clock by one of those deltas. If it's still greater than that fixed delta, it'll run again. And so on.

If your Update loop is very very very slow for a brief period of time (let's say you've done a non-async additive scene load of a massive scene file), it will run a full Update and then do potentially dozens or hundreds of FixedUpdates all at once

edgy sinew
#

Bro … this guy knows everything

polar acorn
#

If your Update loop is super clean and barely takes any time at all, it'll run dozens or hundreds of Updates before enough time has passed for one FixedUpdate

rocky canyon
winged ridge
polar acorn
#

(Unless you VSync or framerate cap it, at least. If you do then it does that "hold for time passed" schtick for Update as well)

Naive way that is almost certainly not optimized but should work:

Loop through all pieces. Have each piece check each direction, and if it encounters a matching piece, check that direction from that piece. If you see another, do one more. If that one also matches, you've found four in a row! Otherwise, go back to the original piece and check the next direction. When you're out of directions, skip to the next piece.

#

Brute force it first until the game works, then you can go back and algorithmify it

Normally, you'd only have to check the most recent piece, but since this one has some randomness to it you might need to check more often

really i am one of those people that knows way too many vim motions and prefers cli apps for a lot of things. None of it matters, how fast you can input stuff is never the bottleneck.

rocky canyon
#

i still cant remember the bloody hotkey to format

edgy sinew
#

I mean the vertical blinking line like ur next typing position

rocky canyon
#

i just cut and paste the whole dang class

#

and let it format that way 😄

fast relic
#

ctrl a, ctrl x, ctrl v

rocky canyon
#

exactly 😉

fast relic
#

-# or just enable format on save

my god, i been following a tutorial on youtube and got stuck at the firsts tep >.<
i followed it to the T, and still it doesnt work. If anyone able to help heres my problem

i am trying to create a fnaf clone, one for halloween and im trying to set up a scroll function on office, ya know. So when player hover on the edges of the screen it moves to that side. but no matter what i do it doesnt budge at all!

heres the code:

using System.Collections.Generic;
using UnityEngine;

public class ScrollArea : MonoBehaviour
{
    public GameObject background;

    public float scrollBoundX;
    public float scrollSpeed;

    public bool left;

    private void OnMouseOver()
    {
        if((background.transform.position.x < scrollBoundX && left) || (background.transform.position.x > scrollBoundX && !left))
        {
            background.transform.position = new Vector2(background.transform.position.x + scrollSpeed, background.transform.position.y);
        }

    }
}

oh... fack

winged ridge
fast relic
#

you need to i think implement IPointerOverHandler (or enter/exit)

#

and make sure you have an event system

shell sorrel
dry tapir
#

thanks guys

#

the tutorial i been following is very old then

winged ridge
dry tapir
#

lol

rocky canyon
#

eh, some people still use the old input system

edgy sinew
#

Maybe it’s from b4 the new input system came out

fast relic
#

i like the new one

rocky canyon
#

for now 😈

eternal needle
rocky canyon
#

rebinding was hella ez

eternal needle
#

Although the input system has existed for years*

fast relic
#

i like it being event/callback based

shell sorrel
#

new one is massivly better

dry tapir
#

im coming from renpy so yeah im lost as hell

shell sorrel
#

takes more setup to use and pushes you into better practices

fast relic
#

also i started with unity 6 so that was the default and might as well use it

winged ridge
#

To be fair.. the new input system is Unreal engines version just changed a bit

edgy sinew
#

Can’t really complain yeah. Do u guys recommend using the built in processor like scale Vector2 etc. deadzone
It’s possible to edit all that at runtime too right?

rocky canyon
#

i use both 🤫

shell sorrel
edgy sinew
#

Well I wouldn’t make a settings menu without dead zone support

shell sorrel
#

the scale can be used as a setting but i often also use it, when i have multiple input devices 1 bind that act quite differently

#

like mouse vs stick inputs for example i often need to scale one

edgy sinew
#

Oh yeah i have separate scale for mouse look / controller look

rocky canyon
#

wait

#

yall talkin like sensitivity multipliers built in?

edgy sinew
#

Hard to find online about “Unity new input system change deadzone at runtime”

#

Yeah those ones. I wanna change them at runtime too

shell sorrel
edgy sinew
#

The more I let Unity handle stuff, the better I feel & the game runs

rocky canyon
#

hell ya

winged ridge
shell sorrel
# rocky canyon hell ya

you will still need some processing after depending on your game, but you can have your scale multipliers be per input device or per bind

rocky canyon
#

i might just get rid of my input class stuff

fast relic
shell sorrel
#

also stuff like normalize and invert and deadzones

edgy sinew
fast relic
#

yeah

rocky canyon
edgy sinew
#

It has invert? i do that manually …

shell sorrel
#

just be carful with normalize most people new misunderstand it and bugger there inputs up

rocky canyon
#

i dont know how many times ive written inversion code

#

oh yea im super familiar wiht normalize

#

altho i always forget about it until i go bak to the code

#

im like tf? Ohhh wait!

#

lol

shell sorrel
#

you can also just write custom processors for the input system

rocky canyon
#

thats pretty awesome to know..

#

but outside my wheelhouse for now

shell sorrel
edgy sinew
#

Ahh ok this is the page i was looking for all along. Nice

rocky canyon
#

gotta focus switching things out and getting rid of some of my redundant code for now

edgy sinew
rocky canyon
edgy sinew
#

I’m so behind i dont have enemy AI even started

winged ridge
#

Pretty much everything in Unity can be redone if you wish, even without access to base code

rocky canyon
#

with only the new input system

fast relic
winged ridge
rocky canyon
#

i had a really smart one.. w/ senses and stuff but got corruptd

edgy sinew
#

If you can just hit me with some key words or things to look out for

fast relic
rocky canyon
#

behaviour trees

edgy sinew
#

I know navmesh is important. I already know state machines

winged ridge
rocky canyon
#

and become a master at the animator

edgy sinew
#

2D doesn’t have navmesh or

rocky canyon
#

nah u have to do a* or something

edgy sinew
#

Why would it, it’s just

winged ridge
#

I was meaning more what's your ai focus

edgy sinew
#

Yes

shell sorrel
#

there are many ways to do pathfinding

rocky canyon
#

i use a hybrid approach

shell sorrel
#

have done 2d with my own A* based on a tilemap or a quad tree

rocky canyon
#

with a navmesh and custom movement logic

edgy sinew
#

I mean basically it’s just the path finding that i don’t know yet

shell sorrel
#

never had a cause where A* on a mesh made more sense in 2d since you need a way to define that mesh

rocky canyon
#

a* a* a*

edgy sinew
#

State, detection with triggers etc, all chill

fast relic
rocky canyon
#

u need to be able to disable the navigation too

#

for things like knockback

#

or anything like that that would move it extra from the pathfinding

#

or u could bake it in i guess

winged ridge
#

I mean the senses idea mentioned was a good one to implement
Sound you just need footsteps decibels
Visual just use raycast
Guess you could implement smell too

edgy sinew
#

What 🤣

rocky canyon
#

senses/ sensor and a sensor array

shell sorrel
rocky canyon
#

ya

edgy sinew
#

I doubt sampling audio would be valuable

rocky canyon
#

for what?

edgy sinew
#

The computer knows where things are, how fast they’re moving (how much noise they’re making)

rocky canyon
#

u gonna build ur ai around the audio? lol

#

ohh that

edgy sinew
#

Nah lol i thought that’s what dragoon meant

rocky canyon
#

no.. that doesnt make sense

#

u could easily do that with proximity and volume levels

edgy sinew
#

Would be cool though. Maybe a quantum computer can do it

rocky canyon
#

cool idea tho..

winged ridge
#

No, I'm saying implementation of sound is easy for the ai

rocky canyon
#

it does remind me this guy made a full echo and reverb system

edgy sinew
#

I saw one guy who was just doing like… “anything that moves makes sound”
With materials and other params

rocky canyon
#

u could walk into a space and the audiowould start bouncing around and echoing

edgy sinew
#

Can’t find that anymore but it was sickkkk

shell sorrel
#

sound for enemy AI is just distnace, and tagging what actions are loud vs quite etc

rocky canyon
edgy sinew
#

Half Life kinda does that i think

shell sorrel
#

no need to overcomplicated it the user will never notice

rocky canyon
#

depending on what ur walkin on u change out the footstep sounds

edgy sinew
#

There’s a lot of math behind which sounds play

shell sorrel
winged ridge
rocky canyon
rocky canyon
#

itd be using materials is what ive seen in teh past

#

to decide the audio but yea if we're still talkin ai i said

u could easily do that with proximity

edgy sinew
#

Running the entire game thru a VST compressor real time lol

rocky canyon
#

so i agree with that part

edgy sinew
#

I wondered if Escape From Tarkov was doing that. That game sounds terrific

#

Nobody’s doing real time compression right … real time reverb, yes though ofc

shell sorrel
winged ridge
#

A reason to use audio is if you wanted to implement perks that adapt things It was mentioned using speed etc. which if you want it so you can perk and run but quieter, you don't want the calculation based on velocity rather than sound it makes... So checking against audio feedback helps
Physics material to define it's parameters

shell sorrel
#

so checking agaisnt audio directly would make game design very hard while keeping things sounding like how you want

#

like audio being triggered is really just invoking a event, so just provide what args are needed for other systems with that

winged ridge
#

Triggering fine, but getting the audio feedback after the variables have been altered based on your conditions (IE crouching, running, grass or broken glass.. etc.) just change decibels and effects and just check against that. The triggering audio sure event invoke

edgy sinew
#

Ngl the audio feedback idea does sound cool

#

Sounds computationally expensive too

shell sorrel
#

its not

winged ridge
shell sorrel
#

its just changing some properties of how something is going to play when it was going to play anyways

edgy sinew
#

Like, sampling an audio source from down the hall, 3 floors down

#

To find out how much of it reached bounced etc or

#

I don’t even know how complex Unity sound simulation is

shell sorrel
#

they are not talking about that though

edgy sinew
#

oh ok nvm then

winged ridge
#

That is what I'm talking about yes vengeful

shell sorrel
#

also defualt unity game audio is not that complicated

winged ridge
#

You mentioned AI I'm talking about a reactive ai based on sound output by your player etc

shell sorrel
#

no bounces are happing, its just how loud is sound, then there is a exp^2 falloff

rocky canyon
fast relic
winged ridge
rocky canyon
edgy sinew
shell sorrel
#

but what i am saying is there are ways to get the exact same outcome that do not involve sampling audio listners

winged ridge
fast relic
#

they just fake it

shell sorrel
#

and are much much cheaper

rocky canyon
#

til u make it

shell sorrel
#

its not even faking it, its just realizing ai's do not care about the audio its self, just the conditions it was made with and where they are relative to it

rocky canyon
#

true.. lmao.. like the clicker zombies in that game.. they dont hear u walkin.. they just know ur way too fkn close.. lol

#

oh, n ur moving..

winged ridge
#

I do feel like we are in the wrong feed for these conversations

bright zodiac
edgy sinew
#

since the terrain is painted with the textures themselves

shell sorrel
edgy sinew
#

Oh fr? hm

#

I thought there’s more complex blending going on etc

shell sorrel
#

so in the case of a terrian or a mesh with vertex color used for different materials you would need to sample it

shell sorrel
edgy sinew
#

So by default it’s the same as dropping a material onto a cube

winged ridge
#

I'd say regardless of whether unity has it or not... Research how it works, try to replicate it, understand the maths and logic behind it, you'll implement it much better (even if you use unity version)

edgy sinew
#

I thought the terrain painting works like that underneath, green red yellow

shell sorrel
#

where you need alternate ways to know what the player is over

rocky canyon
#

u could simply use tags or layers as well if it was the case of an indoor space or walkin on meshs vs the terrain

winged ridge
#

Or a script that you have an enum attached to and just change based on that (get component rather than compare tag)

fast relic
#

get component is more expensive

winged ridge
#

How often do you plan on doing it is the question

edgy sinew
#

I’m hoping, with Procedural Terrain Painter, there’s some way to access the value at some xz location

#

Might not be idk how that thing works

fast relic

#

Nobody will complain if the sound switch is a few frames late

#

(Sometimes the update will coincide and be on time too)

eternal needle
winged ridge
#

Could just have the vectors plotted out stating that between xy and xy is this sound, etc

edgy sinew
#

or wait no Coroutine method would always wait exact same # of frames

eternal needle
#

a coroutine waits a certain amount of frames if you code it to do that. the same way you could do that in update or code it properly to use real time

edgy sinew
#

Oh, yeah. So it could line up with when person changes material they’re on

shell sorrel
#

its 1 frame you loop

#

but now are tieing stuff to exact frame rate which is not great

edgy sinew
#

Yeah im saying, something that for happens “exactly every 5 frames” - it would only be 5 frames late at the most & can other times be only 1 frame late etc

#

I can feel in Dead Cells that they do that for the flying eyeball monster. It looks laggy compared to other monsters

edgy sinew
shell sorrel
#

pretty standard stuff

edgy sinew
shell sorrel
edgy sinew
#

Ah, another “0% FPS gained”

shell sorrel
#

if its continous i would lean towards just a update method and counting frames

#

don't over think things

dry tapir
#

AI is completely frickin useless for unity coding, holy cow

edgy sinew
#

Everyone, cheer! Yay!

it doesnt even tell me whats wrong with the script, nothing it does works
