Anyone succesfully using a one source of truth type state management system ? Redux.NET seems pretty good but im not sure about unity compatibility. I wish Pinia could be ported to C#.

#

I've written my own reactivity system inspired by Vue's and used it in my Unity project. A primitive reactivity system is pretty simple to write, especially if you are willing to make some tradeoffs like not doing automatic dependency tracking, that basically reduces the whole thing to less than 100 LoC.

Hey! I have
-float angle in degrees(can be easily changed to radiants)
-origin vector2 point(game is 2d)
-float distance /magnitude
And i want to generate Vector2 with that angle and distance from origin,

I know how to do this in math like with explinations and calculations, but not sure how to approach it in unity components lol

#

like ofc i can do the long way but Vector2. has so many methods and stuff so i think there should be some easy way

#

nvm found it online lol

Is there an easy way of checking if the transforms parent has a parent with a certain tag?

#

The whole parent of parent and child of child stuff is a little confusing to me

dusky lake

keen lantern
#

Do I just add an extra transform.parent for every parent that I want to go up?

latent latch
#

probably, but not a way I'd code it all. I'd make a specific field for that reference and make sense of what this greater parent is

keen lantern
#

Oh interesting, I would assume that I can do the same with transform.child?

latent latch
#

sure, but if you can do it at editor time, just bind those references on the editor too

Whenever you are running you set the "running" bool on the animator to true and it transitions to the running animation, when you stop, set it to false and it transitions back to idle

What is best practice for using Floats?

slim gate
thick terrace
dusky lake
unreal valley
# slim gate what

If I can represent a float as an Int what's the point of using a float. Essentially is what Im asking.

slim gate
#

you cant, not in most cases. Not sure if I understand

rugged storm
unreal valley
#

Ex. 15%, instead of 0.15f I just do int 15.

dusky lake
rugged storm
#

OH

dusk apex
slim gate
rugged storm
#

than you i can believe i over looked that

slim gate
#

how do you represent 1.5f as an int

heady iris
#

you can find an integer that looks kind of like any given float

slim gate
#

lol

dusk apex
#

If anything, use approximations and ranges when comparing values

heady iris
#

that's not meaningful, though

#

123 kind of looks like 1.23f, but so does the string "1.23"

#

use floats when you need to represent a non-integral value

unreal valley
dusk apex
thick terrace
#

floats are inherently a little bit inaccurate, if you need exact precision you can use int types but for most physics and game logic it doesn't matter

unreal valley
#

I really just wanted to know if I should continue using floats or swap to int's. And in the future if I run into code that I think needs to be a decimal, should I convert to int to avoid these problems.

thick terrace
#

never expect exact equality when comparing the results of float operations, use Mathf.Approximately or whatever

slim gate
#

well if you need floats you use floats and if you dont you use int

unreal valley
#

To go into more detail. It was an accuracy up being applied to a character. Then it got hit with accuracy down. It SHOULD HAVE been 0.

slim gate
#

no reason to use a float if int can do the job

unreal valley
thick terrace
#

things like RPG stats are often better as ints, like currency, you actually do want the exact precision

Hi, I have an event to which I subscribe 2 methods (line 15 of ChillState and line 39 of InputManager), but one method (the one in ChillState) isn't being called when the event is invoked. I used Delegate.GetInvocationList to check that it's actually subscribed and it is. Any thoughts why this might be?

I also used to have Unit Level up bonus's which were in the same boat, it was a aList<StatType,float> . Ex. Strength 2.6 * base each level up. But that can easily be remedied with Mathf.RoundToInt

#

@thick terrace Thanks for the talk.

Any response for this earlier question?

leaden ice
azure heath
# leaden ice I don't see where you invoke the event

Cast is subscribed to OnStartTouch (InputManager Line 103), which is invoked in TouchPressed() (Line 121), which is subscribed to touchPressAction.started (Line 36), which is invoked when you tap the screen

#

it's a bit convoluted ik

leaden ice
#

If you do that it's not going to pick up updates to Cast

#

Cast gets reassigned when you subscribe something new to it

azure heath
#

Oh right yeah I remember now I had the same problem a while ago. That's why I made that AddToUncast() Method on line 139

#

Oh wait that's not quite the same

without using HitInfo I'm assuming is raycasthit, I dunno. just wanted to feed info.

leaden ice

RaycastAll gives RaycastHits too though

rigid island

ya lol also this

warm canopy

correct

#

all the casts do so.

rigid island

for something i am doing
means :p

warm canopy

the CheckBox, CheckSpehere, etc returns just a bool. the *casts methods use raycasthit, and has certain flexibility.

Those are just shortcuts for Overlap methods which are not casts

https://hastebin.com/share/kunebukeku.csharp hi, i am making a script for the player to throw a katana but I have a coroutine that returns the sword to the player that for some reason runs after the sword returns for a little bit (sometimes). this makes it (I think) so after a few consecutive throws, the katana will throw for like half a second and immediately return, not going its full length. (btw this happens when the player hits the enemy not just throwing it into the open sky.) tried making it so when you catch the katana and even when it is in the distance to catch to stop both theThing and the FollowHand coroutine but the issue persists

# solid slate i see

Your variables inside of that coroutine too may not being reset as they are member variables, so make sure stuff like the returning force is changed back to defaults when making a new coroutine.

solid slate
latent latch
#

Ah, I see. My best two guesses would be the values arent resetting, or that you have multiple coroutines running that are changing the values which you may not be aware of.

solid slate
#

yeah that makes sense

latent latch
#

which is why vs debugger is great for debugging coroutines

solid slate
#

how do i debug coroutines tho theres no way to get its status other than bools which isn't really helpoing in my case

latent latch
#

If you're doing it by logs then putting them directly in the coroutine yourself

#

unfortunately not easy to debug per instance though (well, you can identify them inside the coroutine scope, but iterating over a list of coroutines does not yield anything too useful)

Could anyone tell me the most straightfoward way to ensure text (tmp) only shows from one direction, like a real life notecard, even if the material is transparent?

rigid island
rocky basalt
knotty sun
#

I gues this is 3D TMP so parent it to a Quad

rigid island
#

ohhh the 3D one

rocky basalt
#

I may be misunderstanding, but parenting it with a quad didn't fix it

#

and yeah it's 3d

knotty sun
#

i did. Did you flip the Quad 180?

rigid island
#

just seen that lol

#

huh , didnt know it was a fix

rocky basalt
rigid island
#

huh it works

#

nvm didn't work for me

rigid island
rocky basalt
#

It's a VR app where user can grab and manipulate the notecards, so it's a little unorthodox I guess. I'm surprised it isn't more straightforward to solve this lol

rigid island
#

but yeah thought there would be an option on the 3D mesh extra settings to render one sided but alas none I found

rocky basalt
#

I'm actually using the asset Nova for my UI, if you're familiar with it. It's all world space

#

It integrates TextMeshPro

#

Unity's UI just looks like puke to me so I preferred to use Nova. Alas it leads to situations like this tho, hah

rigid island
#

Oh I'm not familiar with it, are you able to use the TextMeshPro UI version of text? I would use that then

rocky basalt
#

Even with that it doesn't seem to make a difference.

#

Oh well, it's not a total gamebreaker for me, but I'm sure I'll run into this issue again someday

knotty sun
rocky basalt
#

are you using sorting layers or anything

knotty sun
#

nope, just put 0.1 on the z of of the text

rocky basalt
#

yeah the problem is the notecard is a semi-transparent 3d object that needs to be consisent on both sides, i just want the backside to not show the text. might require a specific shader or sth

#

Ohh I see, if the quad is like 'inside' the 3d object it will still work I guess

#

What is a good way to have a list of classes that derive from a base class, but which hold unique data types, and then retrieve them?

Like, say, PositionData derives from BaseData, and AnimationData also derives from it.

PositionData holds a Transform, and AnimationData holds an AnimationClip.

I then want a list of BaseData, which contains instances of both PositionData and AnimationData.

Then I have a Function, "PlayAnimation", which takes in a BaseData as a parameter, but I want it to only ATTEMPT to retrieve an AnimationClip from it, so if it's passed an invalid BaseData which doesn't contain that variable, it doesn't throw an error.

Does any of this make sense? Apologies if I'm not explaining it well.

I'm working on a modular statemachine for a turn-based RPG, so I need to be able to build complex custom "actions" that the player can perform.

thick terrace
#

at what point would you pass a non-AnimationData object to PlayAnimation though? i'm wondering why you'd need to avoid something like if (data is AnimationData animationData) PlayAnimation(animationData)

Look, this should explain it better. Here's a snippet of my design document, where I'm trying to piece together the architecture of a state machine for playing character actions.

indigo verge
#

Basically, I want an action to be able to;

Bring up a UI unique to it when selected
Perform a unique action with that UI input
Perform multiple actions if need be, in any order
Provide Control, Modularity, and Complexity for designing actions, playing them out, and modifying them in editor or runtime.

#

So I'm designing it to be polymorphic, and am working on what sort of design elements suit that.

I've read that using coroutines for Turn Based Combat is common, though?

leaden ice
#

Coroutines sound like a nightmare for turn based combat. Coroutines are really just lightweight/poor man's state machines. A full fledged state machine would be better

steady moat
#

No, it is not. It is possible to use them, but definitely a bad idea. You have less control over them. You should favor using your own Update logic.

latent latch
# 
public abstract class EntityConditionsBool : ScriptableObject
{
    public abstract bool EvaluateCondition(IEntity target);
}

public class UnderActiveEffect : EntityConditionsBool
{
    [field: SerializeField] private ActiveEffectSO ActiveEffectSO;

    public override bool EvaluateCondition(IEntity target)
    {
        foreach (ActiveEffectBundle activeEffectBundle in target.ActiveEffectBundles)
        {
            if (activeEffectBundle.ActiveEffectSO == ActiveEffectSO)
            {
                return true;
            }
        }

        return false;
    }
}

So I was thinking of a class like this for conditions for characters. Problem is I'm not too sure of the best way to structure it for return types, as well as being able to work with it on the editor.

#

I dislike the SO Idea as that's a lot of asset bloat so I'mma just use serialize references

#

Another class would be something like this

public abstract class EntityConditionsInt : ScriptableObject
{
    public abstract int EvaluateCondition(IEntity target);
}

public class GetNumActiveEffectStacks : EntityConditionsInt
{
    [field: SerializeField] private ActiveEffectSO ActiveEffectSO;

    public override int EvaluateCondition(IEntity target)
    {
        foreach (ActiveEffectBundle activeEffectBundle in target.ActiveEffectBundles)
        {
            if (activeEffectBundle.ActiveEffectSO == ActiveEffectSO)
            {
                return activeEffectBundle.ActiveEffectApplications.Count;
            }
        }

        return 0;
    }
}```
#

So it's like a class for each type of return value that I want? Ye or nah? I feel like the serialization is what's holding me back here

steady moat
# latent latch I dislike the SO Idea as that's a lot of asset bloat so I'mma just use serialize...

I usually implement "Serialize Condition" as "SerializeReference". Not sure what you are referencing for your issues ?

It seem to me that you are trying to serialized to much "code" and instead you should simply code it. Do not overthinking it, just make a class for every scenario. If you really, really wants to do that, you should instead create a Graph Editor such as what you can see with VisualScripting. It is 100% better to edit "serialize code" in this format.

latent latch
#

Coding it directly would be a solution, but I was looking for like absolute modular code that I could just wrap these in with other classes

#

Probably a bunch of other classes where I do need to know if they have a specific amount of effect stacks, if they are under % hp, stuff like that

steady moat
latent latch
#

Yeah, I can see that and it would probably just be easier to duplicate code if I need to

#

It is nice though a lot of my systems I can just move and replace without touching the underlying code because how component heavy it is

steady moat
#

Obviously, it depends on how much you are going to use those condition and how specific they are.

fervent coyote

Hi there, simple question, how can I get an angle of a direction vector:
_newDir = Handler_Gamehandler.Astro_UnitCircleVector3(transform.eulerAngles.y + (i * 45));
Instead of transform.eulerAngles.y I want to use something like PathfindingDirection.y but it is obviously, 0
Could I have some pointers for this problem?

latent latch
#

Visual scripting does seem like a fine idea too, but it's one of those tools where I'd forget I was even making a game

steady moat
#

If you make a FireBall, just code a FireBall class.

#

No need to make everything abstract and generic.

latent latch
#

but generic projectile that has a chance to explode into smaller fireballs that have a chance to burn the enemy and make the enemy explode when they die is pretty cool too

#

swap out the fireballs for icebolts in a single SO ;)

steady moat
#

It works well if your game is not that complicated. But when you start to have specific condition that only make sense in a specific context it start to being a hindrance more.

latent latch
#

It's unfortunate, but larger reason it is this modular is because I'm bad at having stuff planned out in design

steady moat
latent latch
#

one day I want fireball, the next day I want fireball storm

steady moat
#

Modular means that you are adding limitation and you make a lot of assumption.

#

From the little experience I have, I can guarantee you that the worst you are at planning the worst modular architecture are. It is always 100% easier to replace code of a single whole class then replace code of 5 smaller class and adding context specific module.

I'd do it with a Quaternion that describes one "direction increment" (360° / number of directions to check)
Then multiply it with your direction vector to rotate said direction vector

# 
Quaternion rot = Quaternion.Euler(0, 360 / 6, 0);
Vector3 dir = transform.forward;

for (int i = 0; i < 7; i++)
{
    dir *= rot;
    // use 'dir' for raycast
}

Something roughly like this

steady moat
fervent coyote
simple egret
#

That would be 360 / 8 or just putting 45. Afterwards it depends on the initial direction vector and around which axis you need to rotate it

#

My example assumes a direction that is flat (no Y value) that needs to be rotated around Y

#

(it would make a circle when viewed from the top)

#

Use the stuff in the Debug class to visualize the resulting direction vectors

What's dirA and why is it included in the rotation quaternion?

It's a simple -1 or 1

simple egret
#

Also not sure why you made _newDir a Quaternion, it's supposed to be a Vector3 for it to work properly

fervent coyote
simple egret
#

Right, the operator only works on one side because of matrix multiplication rules

#

_newDir = quat * _newDir;

fervent coyote

Let me try this

Alright, that does work

But I'd like to it to be rounded to the next 45*, the initial rotation

    }

    // Virtual method to be overridden by derived classes
    public abstract void Evoke(ActionStateManager actionStateManager);
}

So basically something like this, as a constructor, so when I have a CombatState, it requires the correct information by default?

fervent coyote

The reason I want to round it the nearest 45* is so I can avoid things like this happening:

There's no way to successfully do a 'GetComponent' on a component you've disabled previously, right?

somber nacelle

have you tried it?

rocky basalt
#

yeah, it returns null. and google indicates it's not possible. wondering if there's some other workaround without having to keep references

somber nacelle

getcomponent should still return a disabled component. are you sure you are calling it on the right object and that the component is disabled and not destroyed?

rocky basalt
#

ok my bad, i read some google results wrong and it confused me. sorry

somber nacelle

you said you tried it

#

Wording is ambiguous, we don't know if you're attempting a disabledComponent.GetComponent<T>() or a GetComponent<SomeDisabledComponentType>()

#

But shouldn't matter, both work

rocky basalt
#

yeah it was returning null because i did something else wrong. i misread some google search results and thought the issue was getcomponent doesn't work on inactive components

simple egret

GetComponent will find and return inactive components, and you can call GetComponent on a disabled component.

Could you be looking at the wrong one?

I would guess that your code is probably referencing a prefab

#

the enemyAI reference

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class BasicEnemyAI : MonoBehaviour
{
    int health = 100;
    EnemyCounterScript counter;

    // Start is called before the first frame update
    void Start()
    {
        counter = FindObjectOfType<EnemyCounterScript>();
    }

    // Update is called once per frame
    void Update()
    {
        if(health <= 0)
        {
            Die();
        }
    }

    void Die()
    {
        counter.enemies--;
        Destroy(gameObject);
        Debug.Log("Die is working");
    }

    public void TakeDamage(int dmg)
    {
        health -= dmg;
        Debug.Log(health);
    }
}
#

That's the enemyAI code

# 
using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class EnemySpawnerControl : MonoBehaviour
{
    [SerializeField] GameObject spawner;
    [SerializeField] GameObject enemyPrefab;

    [SerializeField] BasicEnemyAI enemyAI;

    // Start is called before the first frame update
    void Start()
    {

    // Update is called once per frame
    void Update()

        if(Input.GetKeyDown("p"))
        {
            KillEnemies();
        }
    }

    void Spawn()
    {
        Instantiate(enemyPrefab, spawner.transform.position, Quaternion.identity);
    }

    void KillEnemies()
    {
        enemyAI.TakeDamage(100);
    }
}
leaden ice
# 
    void Update()
    {
        Debug.Log($"My Health is {health}");
        if(health <= 0)
        {
            Die();
        }
    }```
#

Do this

leaden ice
#

given that the enemy seems to be getting spawned in Start

#

and you're ignoring the return value of Instantiate

#

the only possible conclusion is that you have referenced a prefab in the inspector

#

obviously you are then just doing damage to the prefab

#

not to the actual enemy in the scene

#

The reason this might start to "work" when you make it public is that you are then serializing the health variable

#

and so it's saving between play sessions in the editor

#

You need to actually reference the copy of the enemy that you spawn

#

Instantiate returns that reference for you.

Yall, Im confused, in this script: https://hastebin.com/share/ozojexamup.java
the noMoreSeeConnector boolean becomes true after a set of conditions have been met. In the debug log, I can see that it does become true, but for some reason, the else if statement doesnt run. I have tested the else if statement without the boolean check and it works fine, so Im confused why adding the boolean check causes it to stop running, even if its conditions are met.

What have you tried?

I tried using an if statement, but that didn't work.

vagrant blade

Be less vague, show your work, explain the issue and errors.

spring creek
#

"Didn't work" is always gonna be an unhelpful response.
And an if statement is going to of course be a part of any conditional logic, but of course not the actual way of changing the sprite.

pulsar holly
#

I'll show the code.

#

And yes, I formatted it!

spring creek
#

This is still really wild, but yeah, formatted way better.

#

So which part of the code is the attempt on the sprite code?

I think line 33

You should really share the whole thing in an actually halfway decent code site

tawny elkBOT

#

I recommend gdl.space most

pulsar holly
#

Again, I formatted it.

spring creek
#

And why did you say your formatted it again?

pulsar holly
#

Because people kept saying I didn't format it when I did format it.

spring creek
#

Ok, yeah, your previous code cut off the color array, so that was very confusing

pulsar holly
#

Oh

spring creek
#

Lmfao

pulsar holly
#

Ok

spring creek
#

So I see you setting the color of the sprite renderer to a random index in your color array. What is wrong with that?

#

You want to change it to an actual sprite?

pulsar holly
#

No, I was just using sprite as an example for my problem.

#

But the thing is, how do I make the oppentents color the same as the players?

spring creek
pulsar holly

How do I do that? I don't understand what you're saying.

Can someone explain to me why line 45 causes a NullReferenceException error despite me having the EventManager script execute before this script (through Script Execution Order)? It may be important to note that the EventManager script and this script (GermManager) are attached to the same empty GameObject. EventManager uses the Singleton pattern while GermManager does not. I'm willing to provide more details to anyone willing to help.

Im working on a dynamic weather system for my game, starting with rain, though im not sure the best way to handle transitioning surfaces from "dry" to "wet", im using a shader with similar properties to the default lit shader with a "wet value" slider (and other weather-specific params) but this means id have to replace maybe 70% of the materials on most maps and slowly blend between them - what might be a good way to handle this change? Should I make a very large array and add every object in my maps that I want to change the material of? Does it make more sense to put this shader on all surfaces at a "wet value" of 0 even during times where its not going to rain? Or is there maybe a better way to handle this? The idea is for example, is a concrete sidewalk on a sunny day, then it starts raining and slowly that concrete becomes wet/damp/porous, but there are a lot of concrete sidewalks and other surfaces in my maps that should be affected in a similar way

Yo guys! I'm trying to make my raycast ignore the colliders of my own player, but I don't want to use layer's as I'm making a multiplayer game, and would still like for the bullet to hit enemies using the same player prefab.

I tried so many things and this is what I have so far.


foreach (RaycastHit hit in hits)
{
    if (hit.collider.transform.root.gameObject != transform.root.gameObject)
    {
        TrailRenderer trail = Instantiate(bulletTrail, bulletSpawnPoint.position, Quaternion.identity);
        StartCoroutine(SpawnTrail(trail, hit));
        break;
    }
}```

It checks if the collider it hit is a collider of a child in the current gameObject's root parent.
However! When there is another player (spawned in with the same prefab, but still it's own root parent), the bullet also goes straight through him?
I have absolutely no idea anymore how I should make the raycast ignore ONLY the player who is shooting and I've tried sooo many things.
anyone have an idea what to do?
somber nacelle
#

just because you are doing multiplayer doesn't mean you cannot use layers. just put only the local player on a separate layer

(assuming you are doing this check on the local player, that is)

# west lotus Oh I think I get it. Yes you would always have the wetness shader on the materia...

Ah I see, thanks for all the feedback! Out of curiosity, how does this "screen space wetness shader" work? Is there any resources that could explain the technical part behind it? What I dont understand is, if its screen space its not actually applied on specific objects in the scene, so how would it know how to turn things wet or dry? Is it based on camera distance or sampling the camera every frame and then applying "filters" above it before it gets rendered over the screen or something?

leaden ice
#

so they can still know how far away a surface is and what direction it's facing

soft shard
#

Interesting, that sounds like a really cool technique

west lotus
#

In deferred rendering there is this thing called the GBuffer that holds material information for all objects, objects first get rendered into that then light is calculated on the buffer. With the technique in question you would modify the normal and roughness values of the buffer after opaque rendering but before light calculations

#

If you search for screen space wetness, GBuffer wetness online you should find a plethora of resources

soft shard
#

Awesome, ill look more into that, thanks again!

Im thinking about redesigning my object pooling system and could use some tips. i have a singleton pool manager that takes care of all object pools like VFX, bullets, etc. One annoying part is populating the data. I'm stuck either manually linking each prefab in the inspector or letting it create what it needs at runtime when it's first asked for an object, which I feel isnt great. The first time an object is grabbed, itll spawn a lot of them.
As I add more features like "projectiles dont hit the character that spawned it" I feel this system is becoming clunky. I could solve this but I dont want to go deeper into a solution if it isnt good from the start. Im thinking of each character having it's own pool, which would make the above case easier but also enemies on spawn and death will be creating/destroying a lot of objects.
Im not sure if i should remake this or just tough it out with a single pool, anyone have advice on this?

i don't see the problem with using FixedUpdate at 60hz for this, if the framerate goes below 60 it'll just run multiple updates per frame to catch up, it's designed for that

gray mural
thick terrace
#

for a fighting game with deterministic gameplay, surely yes you do

gray mural
#

Coroutine is enough.

thick terrace
#

i don't know why you'd use a coroutine specifically for this, a coroutine is also limited to running in the same fixed update or update loop, but either way you'd probably want to implement some kind of fixed timestep if you're not using FixedUpdate directly

gray mural
thick terrace
#

if it's running forever in a loop, why not just put it in an Update method somewhere?

gray mural
#

This seems the best option. And more comfortable than using Update with Time.deltaTime added to a variable

gray mural
thick terrace
#

WaitForSeconds also only works if your framerate is 60 or higher

gray mural
#

You may use whatever you want, but coroutines are usually much more readable.

Animation Events. That way if you modify the animation you don't have to change a "magic number" in your code

I want to do that instead of using animations Events because I feel like adding each time an event at the end of an animation and defining a specific method to handle what happens at the end of each animation is not really sustainable. Tell me if i'm wrong.

That could be a way, but I suggest you either use string, enum or type as "id".

anyone know how to detect/and or resolve packages that have changed to their default state? Client.Resolve() doesn't seem to do this. Client.Add(URL) works (git packages won't be reverted correctly with anything other than URL, not sure about others), but still not sure how to determine if they've been modified.

just want to check something before I do a stupid:

public class Target
{
  public void Hit()
  {
    // do smth
  }
}

public class Enemy : Target
{
  new public void Hit()
  {
    // do smth else
  }
}

hit.collider.gameObject.GetComponent<Target>().Hit()

Would still do smth else instead of do smth if it hit an Enemy right?

simple egret
#

I don't think so

#

Use proper inheritance with virtual + override

tall scroll
#

if I overrode it then it would work how I expect?

simple egret
#

Yes

#

oki noice

simple egret
#

If you don't plan on having any logic in Target.Hit(), consider making it abstract

tall scroll
#

Noted I do but good to know for the future

leaden ice
#

if you did a proper override... oh SPR2 sorted you out
But you'd get do smth else in both cases if you override properly. (assuming it's actually an Enemy)

In the editor, when you drag an object into your scene, it snaps to other objects that the mouse is hovering over, without overlapping them. Is there a way to replicate this functionality in a runtime scenario?

I've been doing research to try and find something like it, but I can't seem to find anyone implementing something like this.

how do you serialize a graph that has references to gameobjects in a scene ? im using callback reciever interface, i dont know how to keep it all linked

soft shard
# indigo verge I've been doing research to try and find something like it, but I can't seem to ...

That is a mechanic often seen in building games like RTS, TD, etc (you can try looking up these genres for more research), though the general idea would consist of firing a raycast from the mouse screen position to the world position, and placing an object at the hit .point, if the pivot of the object is at the base then that should be all youd need to do, if it is in the middle, youd want to consider adding half the height of the mesh bounds or collider bounds to the hit .point before placing it - you can take it one step further and snap it to some kind of grid if you dont want to allow freeform placing, RTS games tend to do grid snapping, TD games tend to allow freeform since RTS tend to be about managing limited resources and TD tend to be about maxing the landmass, but every game is different

indigo verge
#

I just need to make sure that all of my items have some kind of definition of where their pivot point is.

soft shard
# indigo verge So as long as I have a pivot point, just use that? That's much simpler than wha...

Sounds cool! But seems like you got th general idea, yeah - though if the object does have a rigidbody and you dont want the thing your placing to move around aftter placing it (or you want to create a "preview" or "ghost placement" to see where you would place it without committing to placing it there), you may need to set your rigidbody to kinematic, sleep the rigidbody or freeze its constraints (or possibly disable the collider so physics dont have anything to react to)

indigo verge
#

Yeah, all my items will be kinematic, since I do need them to not be influenced by physics

#

the rigidbody is purely for hit detection, in terms of its actual functionality

soft shard
#

Raycasts can hit colliders without rigidbodies as well, so if you only need it for hit detection, you may not even need the rigidbody at all

yeah

The editor shouldn't crash even if your scripts throw an error.

vapid lynx
#

oh

cosmic rain
#

Where is that code running?

vapid lynx
#

in a grass generator script

somber nacelle
#

is the editor actually crashing or is it freezing? because those are two different things, and which the latter is usually caused by your code

vapid lynx
#

Oh wait

#

i meant freezing 😭

#

my bad

somber nacelle
#

that typically indicates an infinite loop

vapid lynx
# 
        int[] tris = sourceMesh.triangles;
        SourceVertex[] vertices = new SourceVertex[positions.Length];
        for(int i = 0; i < vertices.Length; i++) {
            vertices[i] = new SourceVertex() {
                position = positions[i],
            };
        }```

this is the original code. The only problem is that it covers my entire terrain mesh and i only want it to cover over a certain height
#

so how would i go about doing it in a way that like works

cosmic rain
#

As for the implementation itself, I'm not sure if modifying a mesh like that is gonna produce the results that you expect.🤔

Like obviously object pooling is great for things like bullets that are relatively "simple" with limited logic but you're spawning potentially millions of them over a session.. but even for vfx, I dunno, it seems like maybe it's a close call whether the additional complexity and load costs are worth it

#

bullets I'd say are good pooling candidates, but .. maybe the other stuff isn't until you're talking like N > 100k+ in a session..

#

i dunno .. like in my merge game I create several items per turn that have lots of initialize logic.. shaders.. material cloning.. vfx and particles, sound clip allocation and playing.. and it's pretty invisible even when the user is mashing moves at 2-3/sec

#

even with editor overhead i've never dipped under 60fps or any GC burps

#

i tried to mash through that level as fast as i could to demo

lean sail
# modern creek How many of these things are we talking about? I spawn VFX (with instantiate, fr...

its hard to estimate since i havent planned a whole lot but definitely not near 100 a second. im making a roguelite, enemies likely will cast abilities every few seconds, planning on having a max of like 50 enemies at a time.
I probably dont need pooling, but im also scared of running into a case later when im really deep into the project and suddenly start needing it. Then having to implement it on everything

modern creek
#

each one of those tiny little prefabs has like.. 500+ lines of init code, instantiating and copying materials, vfx, nested prefabs etc.. and i've just never needed to touch optimization

#

I'd probably KISS here and not pool until it's a problem

#

object pooling is great but it's definitely adding a layer of complexity when the cost/benefit might not be clear at the outset

#

imho stuff like this (maybe even localization) is best added when you need it

#

i don't even think retooling to take an Instantiate() approach and moving to a pooling approach is that big a deal

lean sail
#

Ah you're probably right. Ill likely just drop the pooling entirely for now because this really is such a pain. Im pooling an object thats likely gonna be cast once every 10 seconds

modern creek
#

and if you get to the point where you are seeing some performance issues.. at least at that point you can crack open the profiler and examine what's going on.. maybe some errant Resources.Load() call you forgot about or whatever.. and if you just can't get any faster then.. explore the pooled approach imho

#

yeah overengineering a perfect solution is a ... tempting forbidden apple in gamedev.. my opinion is that you kinda gotta get something into market/finished before you worry about the tech stuff like that.. even accruing some tech debt with the benefit of getting shit done is worth it imho

#

like.. the other day my game designer asks me for a list of all the levels (some 600+) in our game with the 1-star/2-star/3-star moves required since the admin tool makes editing a single level easy but not reporting on all the levels at once

lean sail
#

It just feels wrong to be instantiating and destroying so much, but maybe ill just run some tests to prove to myself its not a problem

modern creek
#

my brain starts going.. ok, I can make some denormalized json reporting object that'll get uploaded to our reporting/analytics database, polled once per day.. plugged into google drive

#

and he's like NO NO NO do THIS

#

that code took like 4 minutes and he's like BEAUTIFUL I LOVE IT

#

and meanwhile i'm like 🤮

#

point is.. Instantiate() or even Resources.Load() aren't terrible in small doses, or even before you know you have a problem.. cuz kind of the worst outcome is you spend hours/days/weeks architecting something complex and beautiful and fully featured but then it wasn't even necessary

lean sail
#

Yea true, i guess if i have problems itll likely be from certain overused attacks anyways which I can just make dedicated pools for.

#

not my one off, 30 second cooldown ultimate ability

modern creek
#

or even if it's a huge problem, make the attacks like that use different kinds of bullets instead of 100x bullets

#

like a beam

#

(dunno exactly what your game is but hopefully you get the point.. like.. just change the ultimate a tiny bit to not need 1000 of a small thing)

#

"hit everything on the screen 6 times"

lean sail
#

thats a pretty smart idea, just like a single beam and change the damage rate of it

#

yea my game is just a simple 3d roguelite, you go around and shoot things. items will buff the players and they'll likely get a lot of buffs to the point of possibly having 50x the initial attack speed

modern creek
#

yeah maybe... depending on how many bullets every enemy is shooting at you (like, is this a bullet hell, or is it more like.. uh.. i dunno, something less ha) you might actually need to pool

#

Instantiate is expensive but .. not too bad, and having all the logic constrained to a single bullet/player/npc/turret without needing to do all the pooling "gimme a bullet and set it here and tell me when it hits something and set the owner/properties/speed of it" would be nice

#

if you are pooling, though, i'd probably just have a single pool for bullets, with a BulletManager static/singleton and some methods to get a bullet (and have the bullets do the collision checking and returning themselves to the pool)

#

basically your enemies/players/turrets/whatever should basically not have to do any of the plumbing - just "get me a bullet, set it to (x,y) with a velocity of (x,y) and a damage of (x)" and then forget about it

rigid island
#

use Path.Combine

modern creek
#

no :p

#

I ran that chunk of code exactly one time and then threw it away 🙂

lean sail
modern creek
#

I mean.. obviously I could [over-]engineer the crap out of this little thing.. store the path in player prefs, prompt the user for it, save the output in a document and put it in the database, etc etc etc.. but the 10 line csv solution that took 5 minutes was what the designer needed/wanted and then we were back to other problems 🙂

modern creek
#

whatever is shooting or getting hit by the bullet shouldn't need to do a lot of boilerplate nonsense to get/destroy a bullet

#

i dunno exactly what that looks like for you, but maybe it's a callback on "did hit the player" or some interface that all your shootable/hittable things implement in order to interact with bullets (ie class Player : IHittable, IShootable where hittable has a "GotHit" callback or something, shootable has some things like "shooting direction" or "shooting velocity" or "shooting damage" or whatever), then the player just calls Shoot() and the bulletmanager does all the repeated boilerplate code

lean sail
# modern creek Yeah so ... despite my previous diatribe I'd actually say you're probably on the...

yea but this kinda brings me back to the initial problem. its really annoying to populate this pool. I could populate it when its first asked for a certain prefab and really i might just do that but over time rather than instantly.
and yea the pool right now is also pretty easy to use, its a 1 line solution for anything to get an object. then the object itself is responsible for returning itself to the pool

modern creek
#

why's populating the pool expensive? Aren't you doing this like, once per game session or level or something? I mean, I feel like even if your game is pretty "busy" you only need like.. 1k? 10k?? bullets in the pool

#

even instantiating 10k items in the pool once should only be a few hundred ms... maybe, depending on what each bullet needs to do

royal birch
#

Hi I wonder if somone can help me pls? How do I change an objects physics layer mask after instantiation? The prefab is built as "ignore Raycast" for instantiation but then needs to be switched back to "default" after instantiation.

rigid island
#

lean sail
# modern creek why's populating the pool expensive? Aren't you doing this like, once per game s...

i mean that either i have to manually drag in each object to this pool in inspector, or I can populate the pool manager when something asks for an object for the first time. Basically a difference of doing it in awake vs doing it on demand. Im just unsure if doing it on demand will suffice, because throughout the game there will be new enemies so this will constantly be spawning 100s of objects as the game goes on

modern creek
#

Hm, I guess I don't understand? Maybe show me a screenshot of your inspector pool or some code about how you're getting these pooled objects? It sounds like you're doing something (process-wise, not theoretically) incorrect

#

Like, don't you just have some class BulletManager that's got an Object Pool on it, you instantiate a boatload of the bullets at app/level startup, but then you just GetPooledObject() (or whatever the method is called) whenever you need a single bullet? .. you shouldn't be adding more items to the pool at playtime runtime unless you've suffered some pool starvation, in which case you'd need to just adjust up how many items the pool is making at the beginning

lean sail
royal birch
modern creek
#

wait - are you only instantiatng "prewarm count" bullets?

lean sail
modern creek
#

bullets/explosions/hittexts etc

#

show me more code on your ObjectPoolManager - like, show me where you GetPooledObject

lean sail
modern creek
#

yeah it should be like 100-1000 i imagine.. maybe hittexts/explosions/healtexts are like 50, but bullets probably 1-2000

#

Like, I always thought you slapped an object pool component on something, then did the instantiation of the objects yourself, not create the component yourself with initializers to actions/funcs

cosmic rain
modern creek
#

Like maybe I'm missing something obvious, but it seems like your singleton is creating an object pool at runtime, not populating an object pool that you've defined

lean sail
#

and it does get filled through the create function line 63

modern creek
#

Like why not just make an Object Pool that has some RBProjectiles on it, you instantiate your 100 or 1000 at awake time, then everything in the game just says RBProjectileSingleton.GetMeABullet() and the singleton just does RBpool.GetPooledObject()

#

it doesn't look like that to me? it looks like lines 63-75 create a function that you send as a parameter on line 95

north hearth
modern creek
#

so your singleton creates an object pool that is empty and not initialized

lean sail
#

the pool itself works and has all the objects that i want, its just that it is tedious to assign the references for which object it should spawn in inspector

somber nacelle
modern creek
#

hm.. ok.. I'm probably missing something .. not sure what though 🙂 Sorry that's not more helpful

cosmic rain
modern creek
#

At a glance though, it does seem a bit more complex than needed - aside from bullets.. like I'd use hittexts and healtexts and VFX like explosions just as needed until playtesting shows otherwise

lean sail
modern creek
#

i have this hittext thing which I'm assuming is pretty close to yours.. basically you spawn it at some location and it just rises up over 0.5f sec and tweens the color from whatever to whatever... does some material stuff, some random angle/heights/etc so they don't overlap.. i've spawned hundreds of them on the screen at once and it hasn't been a hotpath thing

north hearth
north hearth
modern creek
#

I'd probably rearchitect your singleton to just be a bullet manager - and the api surface the rest of your game essentially consumes is public Bullet GetBullet() and then returns it to the pool with bullet.gameObject.SetActive(false) which, my understanding, is how you do it (instead of destroying it)

spring creek
mortal egret
#

Thanks, basically I have a moving platform and a Player, when the player jumps on top of the moving platform I check the colliders and I parent the moving platform to the player so they both move together, however when I try to move the player the movement is all stuttery

#

I have tried adding the velocity of the moving platform to the player, however its slow and stuttery

spring creek
#

And what do you do for the platform?

mortal egret
# 
private void FixedUpdate()
{
    _onGround = _collisionDataRetriever.OnGround;
    _onMovingObject = _collisionDataRetriever.OnMovingObject;
    _velocity = _body.velocity;

    _acceleration = _onGround ? _maxAcceleration : _maxAirAcceleration;
    _maxSpeedChange = _acceleration * Time.deltaTime;
    
    if (_onMovingObject)
    {   
        _desiredVelocity = new Vector2(_direction.x, 0f) * Mathf.Max(_maxSpeed + _collisionDataRetriever.MovingObjectVelocity -         _collisionDataRetriever.Friction, 0f);
    }
    _velocity.x = Mathf.MoveTowards(_velocity.x, _desiredVelocity.x, _maxSpeedChange);
    
    _body.velocity = _velocity;
    Debug.Log(_body.velocity);
}

I check if Im on moving object, if yes, I do a new desired velocity, where I add the movement speed of the platform

# 
_desiredVelocity = new Vector2(_direction.x, 0f) * Mathf.Max(_maxSpeed - _collisionDataRetriever.Friction, 0f);
#

for obstacle move, i have a parent which holds the script, a child that is the platform itself with rigidbody etc, and a list of points in which platform goes to

spring creek
#

Ok, so fairly complex movement, but rigidbody velocity based.

I have been, no joke, looking for a solution for 4 hours and none of the google results work, you guys are my last hope before I decide it's not a bug and it's a feature
#

here's how the timeline looks

already saw that thread like

#

10 times

#

ALTHOUGH

#

maybe I could download the project of those examples

#

(which I didn't do because it was like 7 years old and it would be a hell to import)

        for (int i = 0; i < GameDatabase.Instance.ItemList.Count; i++)
        {
            button.onClick.AddListener(() =>
            {
                Game.Instance.inventoryManager.AddItem(i);
            });
        }

Seems like this works like in JS and all butttons will call AddItem() with index being equal to .Count
How do I make sure that each button has its own index passed through onclick event?

fervent furnace
#

copy the i to local variable

#

or make a custom struct/class and capture the variable by your self

plucky inlet
#

Your code currently adds a listener to one button for all items?

#

Why not make the button a prefab and create it from script, so you already have a loop you could hook into and pass in the correct item?

upper pilot
plucky inlet
#

so you got it working?

upper pilot
#

Yes

#

That wasnt the issue, I did what the other person said and created a local variable.

Quite a common problem in a lot of languages

#

Go specifically added a language level fix for this problem somewhat recently.

there is no remove button in the package manager. does anyone know how to remove the package. we want to remove photon

plucky inlet
silver chasm
#

from package manager

primal wind
#

Regular assets don't have a remove button. Only packages

#

You basically just delete them manually

#

For clarification regular assets are what you're importing from the My Assets tab

#

Almost everything else is a package

silver chasm
#

ok

#

so photon is a regular asset?

plucky inlet
#

If its only in your project folder but not in package manager, its an asset and you can get rid of the folder

#

Anyone know how can I load dlls at runtime and add it to the project like if I have a assetBundle that as a script in a gameobject called Potato.cs and I compile that script outisde of the main project then import it with assembly.load how can I make it be acessible in the unity project. Because I want to make my game moddable more or less like KSP or city skylines.

primal wind
#

It's easy and complex at the same time. Look into BepInEx

#

I'm sure you can implement it directly

#

Tho it doesn't have sandboxing

tawny gale
#

It doesn't need to have sandboxing

#

So it's ok I will look into BepInEx

plucky inlet
#

You guys got an idea about why ToJson might give me {} in a custom editor script but not on runtime? Like, the object is there and I can access the list, but ToJson does not seem to like the list when in editor mode. Is there a parameter I am missing to make JsonUtility work in editor scripts?

#

JsonUtility is pretty weird. Plus most people just use Newtonsoft.Json as soon as something doesn't work

JSONUtility's shittyness strikes again

tawny gale
#

What I want to do is import the asset bundle and compile then add the dlls so they are recognizable in the scene of the asset bundle

thick terrace
tawny gale
#

Ok, but how should I approach the creation of the plugin system?

#

because a lot of games don't use the approach of bepinex and compile the scripts at runtime one of the examples is KSP

#

and it uses dlls, asset bundles for the mods I wanted to create something similar so the players don't need to install third party things

thick terrace
#

you can do pretty much anything that isn't creating new unity scripts, so decide what you want modders to be able to customize and create some base interfaces in the game that modders can implement in a plugin

tawny gale
#

But a lot of games can add unity scripts It's not impossible to do it but I don't find how can I do it I'm trying now to build a asset bundle with a .asmdef that I read on a thread that could work

thick terrace
#

sure you can do it, you just have to hack some unity runtime stuff to make it work, which is what bepinex does

tawny gale
#

Yhea and that's what I wanted to understand

primal wind
#

Simplest answer is, create a base class for your mods and when you load the assembly of a mod which uses it, you can load it directly

#

It's essentially what BepInEx does outside of injecting itself into Unity

#

And managing dependencies

#

BepInEx's plugin class is basically a MonoBehaviour. When the game loads, it loads all mods that can be loaded (have the base class and all dependencies satisfied) and add them to a manager GameObject. You can typically see it if you use UnityExplorer in a game with it

I was checking out the profiler and was noticing I was spending a lot of perf on my physics checks, (which I use to check what creatures are near the caster, there are a lot of casters)
and was wondering if it may be more optimal to just iterate through all the creatures and check the distances? or would this be more perf heavy

west lotus
#

Depends on the number of creatures

#

And what physics check you are using

#

And also why a physics check

static matrix
#

im using Physics2D.OverlapCircleAll
number of creatures is like uhhhhhhh
50-100 i think

fervent furnace
#

linear scan how many times?

west lotus
#

And how many casters ?

plucky inlet
west lotus
#

Cause that will multiple for each one

static matrix
#

im using physics because its what I thought was the way to detect all the things that are near something

plucky inlet
static matrix
#

this isn't for the player, its also checking other creatures to see if it needs to switch state to fearing or hunting etc

west lotus
fervent furnace
#

your physical query cant help you to reduce search space, try reduce the overlap radius, if this not work then the only way is to use your own space partitioning/BVH, then perform nearest neighbor search
i realize i havent written my own BVH though

static matrix
#

okay good to know then
i'll try the distance check

west lotus
#

Also consider not doing it every frame or consider splitting the work over multiple frames

static matrix
#

async scary

#

but ill look into it

plucky inlet
#

not async, just not in plain update 😉

#

What about the creatures just adding and removing themselves to a static list when in range for example and do a simple vector distance on themselves against the player? Any issues performancewise?

west lotus
#

I was referring to the good old time-slicing technique. For example in our game we have on average anything between 6k and 10k shooting positions for the enemies to take. Obviously we don’t update each and every one every frame

tawny gale
fervent furnace
#

it is linear scan, ever worse than using physical query to limit search space

static matrix
plucky inlet
#

Ah, just read your post again and you have multiple casters and multiple targets (creatures). Well from that part, I agree with having something like a grid system or similar

before:

 var IsNearFear = Physics2D.OverlapCircleAll(transform.position, FearCheckRadius);
        bool HasFear = false;
        foreach (var item in IsNearFear)
        {

            if(item.gameObject.GetComponent<Creature>()){
                if(Fears.Contains( item.GetComponent<Creature>().MyColor)){
                    scruffState = ScruffState.fearing;
                    HasFear = true;
                }
            }
        }

after:

 var IsNearFear = GameObject.FindObjectsOfType<Creature>();
        bool HasFear = false;
        foreach (var item in IsNearFear)
        {

            if(item.TryGetComponent(out Creature c) && Vector2.Distance(transform.position, item.transform.position) < FearCheckRadius){
                if(Fears.Contains( c.MyColor)){
                    scruffState = ScruffState.fearing;
                    HasFear = true;
                }
            }
        }
#

this is probably faster maybe hopefully

plucky inlet
#

Oh my god, do not do a FindObejctsOfType everytime

#

Get a list going somewhere and your creatures register themselves to it. So you got something to iterate over

static matrix
#

good idea ig

plucky inlet
#

Also the trygetComponent. Just be sure your creatures have the script and your list being of type Creature. soy ou can save that call too

fervent furnace
#

what "Fears" is?
dont tell me it is a list of >100 elements

static matrix
#

"Fears" is the list of colors it is afraid of
its like 4 elements long, Color is an enum

fervent furnace
#

list of 4 elements is fine
the previous version is definitely better, iterate all vs iterate some of them
also use the overloaded version of overlapcircle which takes a list as buffer

static matrix
#

ah whats the overloaded version?

plucky inlet
#

I suggest to just write the most performant of both versions and see, what your profiler does

#

If you do not need physics at all, you could just remove it entirely from your project. But if you need it, you can still try to use overlapsphere and update from there. But as you already tried with your casters and creatures, your outcome was performance issues, right?

Is there a way of seeing logging (Debug.Log and/or Console.WriteLine) in a non-development game build? The only way I've found I've been any to see logs from my monobehavior is to set BuildOptions.Development for BuildPlayerOptions (see code above). When that option isn't present, I don't see logs anymore in the game server. Since I'm on an m2 macbook, it's unclear to me if that's because logging is silenced on non-development builds or if its because there's an issue running the binary

I agree, thats the simplest way if you do not rely on internal unity logs

From what I know, debuglogs get fired no matter the debug bool is on or not for built. so that would work

Not sure about the current way or if it still applies. I am always using IDE or any UI to output what I need

Hey, I am doing a drag item from inventory function and have the drag script like this. When it hits a certain hitbox it goes back to its original place. But I've ran into many problems, sometimes the items disappear when they get dragged after a change of scene, or the original position is never (0,0,0) (the items are attached to a gameObject) and after dragging it many times it starts shifting from its original place. Any help?
