wait lol

#

how do i do the underlined part and not the common mistake :d

leaden ice
#

if you want to destroy the GameObject, pass the GameObject in

terse quarry
#

How do I pass an instance of the class that the script is attached to

leaden ice
#

this is the instance of the class that the code is currently running on

terse quarry
#

Then how do i destroy the object and not just the script

#

but from the script that the object is attached to

leaden ice
#

If you want to get a reference to the GameObject the script is attached to, that would just be this.gameObject or just gameObject (you don't need the this)

ok ive been racking my brain at this for a while im trying to traverse a graph essentially which is my list<list<int>> and im trying to make it start in a random place and assign that to 0 and then adjacent tiles which are the ones to the left and right and above and below it it will randomly choose to go to one of them and assign it 1 then do this so on until roomCount is reached

    {
        new List<int> {-1, -1, -1},
        new List<int> {-1, -1, -1},
        new List<int> {-1, -1, -1}
    };

    public List<List<bool>> roomsVisited = new List<List<bool>>
    {
        new List<bool> {false, false, false},
        new List<bool> {false, false, false},
        new List<bool> {false, false, false}
    };

    public List<List<bool>> roomsValid = new List<List<bool>>
    {
        new List<bool> {false, false, false},
        new List<bool> {false, false, false},
        new List<bool> {false, false, false}

#

is this a graph on a grid?

jaunty sundial
#

i guess yeah

hard viper
#

is it a directed graph

jaunty sundial
#

yeah it should go from start to finish

hard viper
#

uh, but are the edges directed

#

like two positions might have one-way travel between them

jaunty sundial
#

all the positions will be one way travel

hard viper
#

and what sort of graph traversal do you need

#

are you just adding vertices to graph?

jaunty sundial
#

Yes

#

Im trying to make a graph not traverse one

hard viper
#

if you are trying to search, you should use a graph.
if you are trying to create a graph on a grid that satisfies specific constraints, you want the wavefunction collapse algorithm

#

and this does not sound like a directed graph

#

you are building outward, but that does not make the graph a directed graph

#

also, don’t do all this in a Start() call

#

make an actual class to handle this. a POCO

Hi, I have a line of code where I want to aim a hose and spray a target, is this right?

hose.transform.eulerAngles = new Vector3(0, 0, Vector2.Angle(hose.transform.position, target.transform.position));

quaint rock
#

no calculating angle between 2 positional vectors makes no sense

clever bridge
#

i want the hose to point at the target

quaint rock
#

i would do something like

var direction = target.transform.position - hose.transform.position;
hose.transform.rotation = Quaternion.LookRotation(direction.normalized, Vector3.up);
clever bridge
#

it's 2d, is vector3.up the right thing? I want to rotate the z

quaint rock
#

ah i was assuming this is 3d

#

for 2d i would be tempted to just manually do the math

var AngleRad = Mathf.Atan2(target.transform.position.y - hose.transform.position.y, target.transform.position.x - hose.transform.position.x);
var AngleDeg = Mathf.Rad2Deg * AngleRad;
hose.transform.rotation = Quaternion.Euler(0, 0, AngleDeg);

hi im using this line of code:
lastProp.GetComponent<Rigidbody>().AddForce((propPos.transform.position - lastProp.transform.position) * 45, ForceMode.Acceleration);
to move my prop to its destination it works but in like 1 in 5 times it just starts floating around its destination how do i fix that?

quaint rock
#

the multiply it by 45 will not be consistient since the length of the vector will often be much larger then 1 unless you normalize it first

cinder fractal
quaint rock
#

yes though dest is a bad name for it, since its not a position in space its a directional vector

cinder fractal
quaint rock
#

assuming it greatly overshoots, because the velocity does not get smaller as it approaches the target

#

it could be scaled down based on distance to target

cinder fractal
#

maybe the problem is my if statement
private void FixedUpdate()
{
if(itemHeld)
{
if (lastProp.transform.position != propPos.transform.position)
{
Vector3 dir = propPos.transform.position - lastProp.transform.position;
lastProp.GetComponent<Rigidbody>().AddForce(dir.normalized * 45, ForceMode.Acceleration);
}
else
{
lastProp.GetComponent<Rigidbody>().velocity = Vector3.zero;
}
}
}

lunar python
#

should my State be ScriptableObjects or just classes?

quaint rock
lunar python
#

wait it depends on the context?

#

basically my State class is an abstract state for controlling Player's State, AI's/Enemy States, and some Objects' State

lean sail
#

and you would have to create a new instance for each object anyways

lunar python
#

okay I found an article on that, so im just asking whether I should change my approach

quaint rock
lean sail
#

theres a ton of ways to implement it, a State can be anything. as long as its easy for you to use then use it

lunar python
#

does referencing StateMachine in States cause problems in the future or is it having some unnecessary computational burden on the game?

quaint rock
#

would say depends on implementation you got, you are getting maybes since state machines are just a lose programming pattern that can be used for many many things and implemented in many ways

lean sail
#

its just a matter of storing a reference

lunar python
#

Im even referencing player's controller in one of the State's derivatives. Maybe I should just let the states have their neccessary variables instead of passing in all of them

lean sail
#

relaly not sure what the point of this state is, but yea this state has way too much control over what happens. The whole stateMachine.SetNextState(new SlimeIdle()); part needs to go. This is gonna stop you from making reusable states

lunar python
#

Im citing player's position in the State and constantly updating it every frame. So if I have 1 million entities in the world would that be ridiculous?

lean sail
#

if you have 1 million entities in your game, your game wont even run

#

this code is definitely a mess, why is OnEnter calling BaseUpdate

lunar python
lean sail
#

my enemies are simple enough that i dont even care about transitions. If they can enter a state, they enter the one with the highest priority

lunar python
#

do we have priority_queue in C# or some sorts

#

or do I have to recode it

lean sail
#

there is, but thats not what i was referring to. I assign each state a number and then just check which one has the highest number

lunar python
#

let's say I want to make a horde of enemy acts differently. Having priority queue so an enemy would go and be the defense line. Others notice some of their teamates are defenders, they change their priority to ranged attack

#

would be cool

lean sail
#

a priority queue wouldnt really affect what happens here, the enemies in this case would need a sense of their team. You could pass this as a parameter to each state, then they lookup what role is lacking

#

Actually this wouldnt really happen inside the state machine, being ranged/melee/whatever would be the states. An enemy controller script would be looking that information up, and then requesting a state transition

#

oh ye

#

i forgot to move that to the SlimeMovementBase

but it is going to be depracated soon with better management

Hi, I have some code to point a hose at a target point, but it's not quite doing it right, I have a player moving back and forth, their scale x is 1 or -1, when it's -1, the aim is off a bit and I don't know why

        var AngleDeg = Mathf.Rad2Deg * AngleRad * tank.transform.localScale.x;
        hose.transform.rotation = Quaternion.Euler(0, 0, AngleDeg);```
frosty snow
#

how does the view model system differ from the entity component system

cosmic rain
#

One separates visuals logic and business logic. The other separates data and behavior.

They're kind of in different realms entirely.

frosty snow
#

which would be easier for saving and restoring data / application state ?

cosmic rain
#

Like a save system?

frosty snow
#

yea

#

im trying to make a hot-reload system

#

and i would like it to be easy for people to implement hot-reload compatibility

without for example, needing to make every class they use/make annotated with serializable annotations and such

cosmic rain
#

Then maybe ECS? It should make it easier to save/load the data as is.

#

Honestly, I'm not sure how view model pattern even is relevant in this context.

frosty snow
#

the view model pattern basically just ummm operates on read-only data right?

#

(the actual data is writable outside the model but read-only inside the model)

Hi, I'm writing a server that I'd like to use to perform a number of simulations quickly, independent of frame rate (the server wouldn't be rendering anything). Is it as easy as putting the code in FixedUpdate? I'm having a difficult time googling an answer, and I tried using GPT, but it said to use async/await. I thought async would still run synchronously if there is no await. If anyone could point me in the right direction, I would appreciate it.

frosty snow
#

Physics.step and multiple Physics Scenes (i think)

mellow sigil
#

If you just want to run a simulation and get the result, you don't need to put it anywhere. Just run the simulation.

pale plover
#

I feel dumb, thank you. I had a feeling I was making it more complicated than it needed to be

frosty snow
#

do note that this depends on what you require

#

for example, if you need to simulate physics temporarily (eg, for predicions and such) then a second physics scene must be used

if you need to adjust the physics speed (how many times fixed update is called) then Time.fixedDeltaTime and Time.maximumDeltaTime can be used to achive that, the lower its value the faster the simulation will run

pale plover
#

thank you, again. Appreciate it

cosmic rain
frosty snow
#

how so ?

cosmic rain
#

Because it's irrelevant. The main concept is separation of business logic from presentation.

frosty snow
#

eg

Label {
    public string text => data().text();
    // or a more effiecent binding that updates the text variable and causes a redraw when ever data.text changes
    ...
}
cosmic rain
#

This is just a property that retrieves a value from the data. I don't see how it's alone is relevant to a design pattern.

#

Typically in Model view you'd have 2 classes that perform the model and the view role. The model class is responsible only for the business logic, while the view is responsible for the presentation logic. The interactions between them and their specific implementation doesn't really matter.

#

There are all sorts of variations like MVC and MVVM, but the general idea is separation of logic from presentation.

frosty snow
#

or similar to such

cosmic rain
#

Data binding is not necessarily related to MV.

I'm saving data through BinaryFormatter, and I get such error when im trying to save a List of scriptable objects.

SerializationException: Type 'UnityEngine.ScriptableObject' in Assembly 'UnityEngine.CoreModule, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.

#

i have marked it as serializable

#

so im not sure what's wrong

quartz folio
deft timber
#

or am I trying to serialize something, that just cant be?

deft timber
deft timber
quartz folio
#

and do they inherit from ScriptableObject

deft timber
# 
[System.Serializable]
public class PlayerDeckUnitSlot
{
    [Header("Settings")]
    public UnitData assignedUnit;
    public bool isAssigned = false;
}
#

no

quartz folio
#

They have a UnitData in them.

#

Which does, which is the problem

deft timber
#

so there is no way to save the scriptable objects at all?

#

cannot change the architecture for it that far into development

#

I guess I can make some kind of workaround of it, since i have serializable Dictionary<enum, UnitData>

#

so i can save the enum, then map it to proper UnitData, then set it to the loaded list

Can I get same random values using Random.InitState(seed) on different computers? I generate some data on one computer and Id like another computer to generate exactly the same data. I tried to find answers on google so hard, but I feel like some ppl think its possible and some its not

#

I did try it, but didnt work

knotty sun
rigid island
#

indeed, if "its not working" something is wrong with how you're generating

south violet
#

It seems it doesnt always work. I generated data twice with the same seed on one PC and data were exactly the same, but when I tried to generate on different PC and compare then data from these two PCs, they werent equal

break down the problem into smaller issues to solve

Right?

knotty sun
#

I just roll my own Random, it's not that hard

dawn nebula
#

How very programmer of you.

knotty sun
#

that's me, old, old school

dawn nebula
#

I can see the value of a Static random class, but I think I would have preferred like...

#

Random.Default.Range(...);

#

Instead.

#

Like some default static instance was always available, but nothing was stopping you from instantiating another.

knotty sun
dawn nebula
#

why is that?

knotty sun
#

not random enough, way too much chance of it being manipulated

dawn nebula

huh

Hey guys, I have an issue where when a level reloads, when the player tries to aim, I get missing reference errors. Ive looked about online but issues tend to be personalised. The thing with my debugging is the references still seem to be there in play mode meaning the script should be able to access it

(for e.g line 125 LeanTween.scale(crosshairDot, new Vector2(1f, 1f), .2f) .setOnComplete(() => Crosshair());, the script still has this game object within the inspector, this is the same for the animator)

Any help?

# lunar python did you destroy any object on reload?

not that i am aware of, i have a trigger where when the player falls it simply reloads the scene (delay for a fade animation) private IEnumerator OpenLevel(float waitTime, string level) { yield return new WaitForSeconds(waitTime); SceneManager.LoadScene(level); }
Its weird as everything else works and those references are still present in inspector

#

and the original crosshair() function still plays upon start to make it appear in the first place

#

meaning... it exists

dawn nebula
#

But... ya.

#

Bit awkward.

lunar python
#

maybe get someone experienced in a call would be quick fix

fiery path
rigid island
tawny elkBOT
lunar python
#

do you use drag and drop or GetComponent<>

fiery path
lunar python
#

hmm thats kinda buggy

fiery path
#

still learning

rigid island
#

no

fiery path
#

also aware the manager can be a lot more optimised

lunar python
#

no but i just don't like idea

fiery path
#

yeah thats fair

rigid island
#

put this before line 125 Debug.Log(crosshairDot, gameObject)

#

also you should probably fix your other errors so your console isn't spammed with errors

fiery path
#

is it to do with the ui manager instance

rigid island
#

dont clip screeeshot of error, show the whole stack trace

rigid island
fiery path
#

1 of each

rigid island
#

looks like you're trying to use functions on destroyed animator component

rigid island
#

how many did it print

fiery path
#

the animator it is referring to is still there in inspector which is the confusing part to my head tho

image.png
fiery path
lunar python
#

also remember to apply to prefab

rigid island
lunar python
#

did you destroy the gameobject and instantiate a prefab without the applied changes?

fiery path
#

i am unsure but it is fixed

    {
        if (_animator != null)
        {
            myCamera.Priority += camPriority;
            uiManager.CrosshairAimed();
            _animator.SetBool("isAim", true);
        }
    }

    private void StopAimPlayer()
    {
        if (_animator != null)
        {
            myCamera.Priority -= camPriority;
            uiManager.ResetCrosshair();
            _animator.SetBool("isAim", false);
        }
    }``` 
I added a null check but now it works fine
#

might have been a prefab issue

#

really dont know

#

thank you tho guys

lunar python
#

also check for script execution order

#

as some objects may load in before others

#

so make custom Start so the dependencies gets loaded in first

rigid island
fiery path
#

im aware

#

is referencing my ui manager within awake an issue

rigid island
lunar python
#

remove the null

#

and check again

#

might cause future headache if we patch things like that

fiery path
#

im not spawning the prefab with the animator at any point

rigid island
fiery path
#

or to my knowledge destroying it

fiery path
#

uiManager.ResetCrosshair();

#

for example

rigid island
lunar python
#

give full code

fiery path
#

so this seems to be the main script causing the issue

#

the interesting thing is the same animator is being used by the player controller script

#

and the movement animations play fine, no null error

# 
        _animator.SetFloat("side", sideValue);```
#

seems to only be aiming

#

again, only when reloaded

rigid island
#

your sub to those inputs look wrong

hello, I have encountered a problem can you help. My for loop returns 7 times and my value always returns 7 times 1 or 7 times 0 when I restart the project for example: 1 1 1 1 1 1 1 1 1. What I want is that my test value returns 1 or 0 7 times example: 1 0 1 1 0 1 1 1 1 0 like this. here

i’ve been having issues setting an animated tile back to its initial start frame. I’ve been trying Tilemap.SetAnimationTime(), but when I do, I see the tile flicker, but still end in the wrong frame.
Advice?

lunar python
#

idk what is InputAction

rigid island
hard viper
rigid island
#

wel diff values but same variable

lunar python
sage plaza
lunar python
#

if test is string or array do test[i] where i is index

rigid island
#

that wont work

sage plaza
#

test is int

lunar python
#

what

sage plaza
#

I'll tell you what I'm trying to do.

rigid island
lunar python
#

oh

rigid island
lunar python
#

so string is immutable in c#?

rigid island
#

correct

sage plaza
#

I have car parts and I am trying to determine whether they are damaged or not, so I used bool and I will determine whether it is damaged or undamaged with random, this is the code I wrote.

`bool testbool;
int test;
public void ValuesRandom()
{
for (int i = 0; i < damagedParts.Count; i++)
{
test = Random.Range(0, 2);
}

    for (int i = 0; i < damagedParts.Count; i++)
    {
        if (test == 0)
            testbool = true;
        else if (test == 1)
            testbool = false;

        damagedParts[i] = testbool;
    }
}`
rigid island
tawny elkBOT
lunar python
rigid island
#

just set damaged directly on the parts during the loop

sage plaza
#

yeah

rigid island
#

you dont need this int assigment at all

lunar python
#

you need an array which is a series of numbers to store multiple numbers

rigid island
#

nah you dont even need that

#

if the parts are already in array they should just have an isDamaged bool

lunar python
#

yes but we need him to know how code works

rigid island
rigid island
#

they need to learn how to iterate through their carparts and assign the value depending on a random number

lunar python
#

I think he is thinking that the 2 for loops are executed at same time

sage plaza
#

im junior dev this is my case a actually

lunar python
#

code executes from top to bottom

rigid island
#

the logic is somewhat valid but not for 7 times

sage plaza
rigid island
#

again also doing 2 loops for that is unecessary

sage plaza
#

yeah i know im just testing

rigid island
lunar python
#

anyway this should move to begginner

lunar python
#

dont give him code teach him

sage plaza
rigid island
sage plaza
#

Actually, I'm not very new, I just said yes to avoid beating around the bush.

rigid island
#

you're def missing some basics on how the code is working

lunar python
#

anyway I have 2 collider in the same object. How do I GetComponent<>() to one specific

rigid island
#

you don't , you use the inspector

#

if the collider types are different then you find the specific type

sage plaza
lunar python
#

what if my future enemy has a random number of child objects with colliders

#

how do I control it

rigid island
#

you put them in an array of Colliders and you can loop through them

#

GetComponents is also a thing

lunar python
#

okay nice

sage latch
#

You could also create a component on the enemy that keeps track of one of them. Then make a public getter

rigid island
#

yeah also an option

lunar python
#

why cant we have name for colliders

#

would be nicer

hard viper
#

yeah, you need to use a monobehaviour to link them to specific variables for that

#

I’m trying to make a system where a front of ice/heat can propagate through a large tilemap of water/ice, affecting the nearest neighbor over time. Any suggestion on how to best represent/do this?

lunar python
#

Also do we have some way of having code hierarchy in inspector

hard viper
#

inspector for a given script shows different fields depending on the order of attributes you give.

lunar python
#

I mean by script hierarcy like in go dot

you can set a gameobject as a child of another gameobject

#

if that is what you mean

#

so I might have my player gameobject with a collider and player movement etc. Then a child gameobject might be a sword it is holding, which has its own collider and sword script.

#

but multiple components within the same gameobject are basically not sorted with any hierarchy

#

Godot enforces more hierarchy in that regard

#

Unity has a hierarchy of gameobjects, which contain scripts. Unity does not have a hierarchy of scripts.

I have a general concept question for a project I'm doing but not sure where to start.
I want to convert a video into a image sequence.
From that video sequence convert it to a sprite sheet.
Then apply that sprite sheet to a character
I know I can do this outside of Unity, but I want this entire process to work within my Unity Game.

Anyone got any ideas?

i’ll take a look at the vid later, when I have a break. In my case, I’m thinking about making the delay time a float.

#

one note is that it isn’t a state function. If I have water in contact with ice, the result is different if I’m propagating a freezing wave outward, of thawing wave

#

actually, I have an idea to use a separate grid. ty tina

Hey everyone, just working on optimising some code right now. I've found a section that updates a sprite every frame, however often it's just setting it back to the same sprite. I presume this has a performance cost associated with it, so I'm trying to figure out how to best improve this. Currently the code is as follows

sprite1
sprite2

if sprite != sprite1 && other condition
  sprite = sprite1
else if sprite != sprite2
  sprite = sprite2

Is there an even more performant way of doing this check? Obviously I'm comparing sprites, and I'm unsure if it just uses the memory address to check if the references are the same or if it's doing something heavier. I considered checking the name or the hash. What do you think?

somber nacelle
#

I presume this has a performance cost associated with it
have you profiled it to see if there actually is a performance cost worth worrying about?

lucid tulip
#

Well there is noticeable lag caused by this system on device, however I can't see anything particular in editor unfortunately. Because of this I'm working through the code just to see what could be causing potential issues with it

#

I should note that I'm shooting in the dark here because the profiler isn't providing any useful information about my situation

#

Or more likely I'm missing something

#

Also is it even worth getting the hash? I've just realised I could just as well use a bool

rigid island
lucid tulip
rigid island
#

send them a dev build and you can also setup a remote profiling by IP connect

lunar python
lucid tulip
#

just an int check if level >= level threshold

lunar python
#

setting sprites isn't that costly

#

you can use switch instead but that would be premature optimization

lucid tulip
#

It was being set in the update loop, so I figured it's definitely doing more than it needs to

lunar python
#

an animation can even change sprites tens of time per second

lucid tulip
#

true

lunar python
#

anyway how is that even costly

#

can I see full code?

lucid tulip
#

Unfortunately I can't show the code. I don't reckon that is the issue anyway, I just wanted to know if/how much a difference it would make

#

I'm looking at some previous commits to see if anything jumps out at me. My biggest issue is not being able to replicate any performance issues on my end...

How does LogAssert.Expect() work with the Unity.Logging package?
The following code fails:

LogAssert.Expect(LogType.Log, "All allies are defeated");
combatLoop.EndOfTurn(); // runs Unity.Logging.Log.Info("All allies are defeated");

While this succeeds:

LogAssert.Expect(LogType.Log, "All allies are defeated");
Debug.Log("All allies are defeated");

#

I don't see this case mentioned in the Docs, and Google hasn't been helpful either.
In both cases, I see a Log appear in the Console

leaden ice
wraith spear
# leaden ice What does the success of failure message say? Are you sure it's not failing for ...

Fairly certain. The message is Expected log did not appear: [Log] All allies are defeated.
The only difference is the way it's logged (Debug.Log vs Log.Info). And I do see the Log.Info message in the Console, so I know it does get hit:

All allies are defeated
Logger:Log(LoggingLevel, String) (at Assets/Scripts/Logger.cs:29)
Battle.<AlliesAreDefeated>d__13:MoveNext() (at Assets/Scripts/Battle/CombatLoop.cs:159)

It does get called from an IEnumerator (CombatLoop start the Coroutine). Does that matter?

#

And the messages are identical; I've copy-pasted them over

leaden ice
wraith spear
# leaden ice What is Log.Info. Isn't LogAssert.Except expecting Debug.Log calls specifically?

It's from the Unity.Logging package. Full method call is Unity.Logging.Log.Info(string message);
And I don't know for sure if it is expecting *onl Debug.Log. The official documentation says:

"LogAssert lets you expect Unity log messages that would otherwise cause the test to fail. A test fails if Unity logs a message other than a regular log or warning message. Use LogAssert to check for an expected message in the log so that the test does not fail when Unity logs the message.

Use LogAssert.Expect before running the code under test, as the check for expected logs runs at the end of each frame.

A test also reports a failure, if an expected message does not appear, or if Unity does not log any regular log or warning messages."

#

I would expect it to work with the Unity.Logging package, but it seems like it doesn't

leaden ice
wraith spear
#

Difference in message:
Log.Info:

All allies are defeated
Logger:Log(LoggingLevel, String) (at Assets/Scripts/Logger.cs:29)
Battle.<AlliesAreDefeated>d__13:MoveNext() (at Assets/Scripts/Battle/CombatLoop.cs:159)

Debug.Log

All allies are defeated
UnityEngine.Debug:Log (object)
Tests.Battle.CombatLoopTests/<Allies_Are_Defeated_Triggers_When_All_Allies_Are_Defeated>d__0:MoveNext () (at Assets/Play Tests/Battle/CombatLoopTests.cs:32)
UnityEngine.SetupCoroutine:InvokeMoveNext (System.Collections.IEnumerator,intptr)

leaden ice
#

I guess you have your answer then?

wraith spear
#

I can't really change the Logging in my game to Debug.Log. However, I would very much like to test whether messages appear in the Logging

wraith spear
leaden ice
#

gotcha I think I'm finally caught up on your original question 😆

wraith spear
#

Npnp

#

Ah, maybe Unity.Logging has its own Test package, I'll have a look

#

Yeah, found the answer:

It’s not natively supported by the Test Framework, a workaround is to use the WriteTo.UnityDebugLog sink at the cost of a negative performance impact.

Thanks for the help regardless, Praetor

hey i need to deserialize json formatted string into classes, but there is like 5 diffrent classes. How do I determine witch class to use? Every class has a "type" key (string)
thanks

wait

#

can I use something like

public class Base{
  public string Type;
}

public class A : Base{
  public float test;
}
[...]

you could, but you would still need to do things twice

#

first get base, figure out what type is, then choose your final type for the 2nd pass

Are you using baked lighting?

You have realtime lighting and baked lighting. Baked lighting "bakes" the lighting data into the scene's textures. Realtime lighting allows for moving lights. If you're not bothered about performance you can make sure your lights are set to real time, otherwise go to Window>Lighting and bake the lighting into the scene

For example you can have a List<NavMeshAgent> to store as many agents as you want.

you put a NavMeshAgent into an array

#

You can

leaden ice
#

once you have a reference to a specific agent you can call functions on it

#

you would need to get the specific agent you want out of the list and do what you want with it

#

If you want to do something to all of them, you can use a loop to iterate over all of them and do the same thing to each

any idea how can i code a script that will always keep a folder opened in assets inspector window? (not the inspector, just the unity's file window)

maybe if theres a callback whenever you click on files

then i could check if its opened there, if not then open

#

idk if theres even api to do this

for example keep this always open (so that its children are visible in the folder tree)

Is there any suggestions on how to make multiple objects move as one until a specific action is done and then make only some of the objects start moving seperatly?

hexed oak
#

parent them all under one gameobject, then when specific action is done swap some to a different parent

orchid finch
#

Should have specified that objects are physics based or will work either way?

lean sail
orchid finch
#

that can be broken down

west lotus
#

Keep the rigidbodies on the pieces kinematic then when they are hit set them to non kinematic and detach them from the parent

#

That would be the simplest option. Now if we are talking actual demolition there a bunch more work to be done on clustering, separation, structural integrity and so on.

#

Ie if you don’t want floating pieces

lean sail
# orchid finch that can be broken down

Broken like piece by piece? Or damage any piece of a wall and then it all breaks?
What Uri said above works for piece by piece. If you want to destroy the whole thing I'd just have it as one object and replace the whole wall with a destroyed version when it should break

orchid finch
#

broken into like cubes/parts

ig it will work in a way kind of

    [SerializeField]
    private int maxValue = 10;
    [SerializeField]
    [Range(0.1f, 10f)]
    private float noiseScale = 1f;

}

Then, in another class, I serialize a list of the "Wave" above. When I add a new instance to the list via the inspector, it's added with default values rather than the ones defined above / the standard behaviour when adding components.

How can I make sure new instances are added with the values defined in the class?

Hey, I have a little problem. I have a hex grid system, with a pathfinding system. My list of tiles for a path is given correctly. I wanna add some directional arrows to show the path on the tiles. the arrow is just a sprite renderer (it's in 3D). I tried everything to rotate the arrow at index N to the tile at N+1, but it never works, does anyone could help me please? 🙂

strange yacht
#

Hi, could you provide your current code for the arrow rotation

warm night
#

Sure, I'll give you that

#

I tried this

 public void ShowArrowTowards(Tile tile)
 {
     Vector3 direction = (tile.transform.position - transform.position).normalized;
     this.displayInformationRenderer.sprite = arrowSprite;

     if (direction != Vector3.zero)
     {
         float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;

         angle -= 90f; 
         displayInformationRenderer.transform.rotation = Quaternion.Euler(0f, 0f, angle);
     }
 }
#

I also tried transform.Rotate(); transform.LookAt(); transform.eulerAngles = new Vector3(..)

#

I never found a solution on internet lmao

strange yacht
#

and what are you seeing ? no rotation or incorrect rotation ?

warm night
#

Incorrect rotation, let me show you what that code gives me

#

the arrows are... really facing up. However, if i took one in the scene, and just set rotation to (0f, 0f) on x and y, and manually change the z value, it rotates well, so that's why I tried to do

Quaternion.Euler(0f, 0f, angle);
#

This is the rotation given by the inspector

image.png
#

idk why it gives me this, but... yeah

strange yacht
#

and on the picture you set the arrows to indicate toward which direction ?

dusk apex
#

Maybe set the local rotation if you want the inspector to match?

warm night
#

Each arrow has to indicate towards the next tile, i tried to raycast to see the path, and it goes well, but not the rotation

quartz folio
#

Don't look at the inspector and assume it's going to be the same value you set it code. Euler angles derived from quaternions can be different representations of the same orientation

dusk apex
#

Else print the rotation in euler and ignore the inspector value

warm night
#

Okay i see

warm night
dusk apex
#

I don't think you'll get what you want but maybe it'll be a bit more understandable from the inspector relative to location rotation.

warm night
#

fact yup, now we can see flat arrows, but as u said, they're not facing to the next tile

image.png
#

that's completely weird, because I'm taking Atan2 of the direction, so it has to get the good value tbh

dusk apex
#

Log the result and values to see if they're what you're expecting.

#

Were you feeding arc tan directions?

warm night
#

I'm doing some raycasting and printing values, but to be honest for the first arrow, it has to be approximatively 120 in Z axis, but it returns me 90

dusk apex
#

Ah nevermind

warm night
#

The raycast of the direction is correct, as u can see

image.png
dusk apex
#

Was the direction vector as expected for each?

warm night
#

yeah

dusk apex
#

You should be able to visually confirm

warm night
#

the direction is as expected yeah

dusk apex
#

So the resulting angle isn't?

warm night
#

yeah

#

that's the problem, and a weird one

#

maybe i'm not using the Mathf.Atan2 correctly, i'm not kinda good at math

dusk apex
#

The value would be in radians. Is that what you're expecting?

warm night
#

Yeah, but i''m converting it in degrees

#

using Mathf.Rad2Deg

dusk apex
#

Ah, I'm on mobile. The screen is small.

warm night
#

sorry :/

#

i just saw something on a website which tells me that it can be caused by the values passed in mathf.atan2

dusk apex
#

Can you log the direction vector and the resulting angle?

warm night
#

They're using Mathf.Atan2(-direction.y, direction.x) instead of Mathf.Atan2(direction.y, direction.x), i'm gonna use that

#

sure

dusk apex
#

Showing us the console log, if possible.

warm night
#

yeah yeah np

#

I tried to put -direction.y to try as well

#

and just so you know, i just do angle -= 90f, as well so if u want the real result of Atan2, you'll have to add 90

dusk apex
#

So y is zero

#

Maybe you're wanting z/x?

warm night
#

oooooh

#

that's smart

dusk apex
#

arctan(z, x)

warm night
#

let me try,

somber nacelle
#

also if you just want the sprite's Y axis to point at the position, just assign its transform.up to the direction. no need for the atan2

warm night
somber nacelle
#

displayInformationRenderer.transform.up = direction

warm night
#

now we have something interesting

image.png
#

I'm gonna try your thing instead @somber nacelle

#

tbh i didn't even know that we can change transform.up

#

that's weird

image.png
dusk apex
#

There seems to be a pattern UnityChanHuh

warm night
somber nacelle
#

show the current code

warm night
#

or invert, i'm gonna try all possibilities

# 
public void ShowArrowTowards(Tile tile)
{
    Vector3 direction = (tile.transform.position - transform.position).normalized;
    this.displayInformationRenderer.sprite = arrowSprite;

    Debug.DrawLine(GetDisplayRenderer().position, tile.GetDisplayRenderer().position, Color.red);

    if (direction != Vector3.zero)
    {
         float angle = Mathf.Atan2(direction.z, direction.x) * Mathf.Rad2Deg;
         angle -= 90f;
         Debug.Log("direction vector = " + direction + " | angle = " + angle);
         displayInformationRenderer.transform.localRotation = Quaternion.Euler(0f, 0f, angle);
       // displayInformationRenderer.transform.up = direction;
    }
}
#

That code is for the first screenshot

#

And if you want the code for the 2nd one, just inverse the comment and code in the if statement lmao

#

i tried -direction.z, direction.x and i got this, i think if i delete the -=90f, it could work

how many people use giant switch case blocks for logic?

#

i try to avoid that as much as I can, and use delegates, but I feel like I should just use switch case more liberally

latent latch
#

usually up to 5 then I break it more into sub-types / sub-states

quaint rock
#

like what it switching on?

#

if its just a enum, and its getting big you can just pass functions around directly, or use a interface type

hard viper
#

when I say giant switch case blocks, I mean 20+. It doesn’t depend. You do this, or you don’t.

cosmic rain
#

What are you gonna do with that information though?😅

quaint rock
#

20 is still in the it depends region it really depends on what its for

#

what you are switching on and why

#

like if its a switch over enums, and the enums are only used for choosing what logic to run

#

would just pass functions directly in that case, or a object that has overriden methods

#

really most questions like this come down to use what works for you in the moment, and if you start feeling a lot of friction doing that figure out why and come up with a new approach

hard viper
#

reading the room

lean sail
#

If you're looking for justification to keep your current method, maybe start look at redesigning.
Out of like 100 scripts I have, I think I used a switch once on an enum with 5 options. Having to do this often sounds like a design issue

hard viper
#

my personal limit on switch case blocks is 6

#

but i see some people writing some giant goddamn switch case blocks, and I want to know how common of a practice it is

lunar python
#

you dont write giant switch cases

#

learn how loops work

hard viper
#

how does a loop replace a switch case, my man

lunar python
#

a loop with conditional ifs and an array of constants

lean sail
#

What on earth..

lunar python
#

if the conditions have a pattern better code that way

hard viper
#

maybe help me out. I have this code:
switch (cardType) {
case “PotOfGreed”: hand.size += 2; break;
case “Cow” : milk++; break;
case “Corn”: player.health++; break;
…
}

#

how does this turn into a loop

lunar python
#

you dont code it that way

hard viper
#

no. you said to learn how loops work

lunar python
#

use an integace

#

interface

hard viper
#

no. you said to learn how loops work. Now you teach how loops fix this issue

lunar python
#

these dont have any patterns

hard viper
#

i was working with a guy the other day with a switch-case block with >120 cases

lunar python
#

that would be hard to read

hard viper
#

trying to get him to something not cursed. and I want to know how common that practice is

lunar python
#

i dont think anyone would want to go through all of that

hard viper
#

yet here we are

#

it exists

#

and it is exactly as cursed as papa always said

lunar python
#

just interface ICardEffects and executeEffects()

hard viper
#

I tried to guide him towards that, but he’s on GDScript, which lacks interface support.

#

So that is not an option

lunar python
#

you could try abstract classes

hard viper
#

that’s what I was leaning towards.

#

anyway, point being, I want to know if there are any more degenerates out there

#

writing giant switch case blocks

lunar python
#

yes my friend bruteforced 100 if else to solve a problem for kindergartens that only requires 5 lines

lean sail
#

Even with the interfaces or abstract class, you lose out on some ease of setting things up in inspector. Now you have to do some custom editor stuff

hard viper
#

i think the core question is to tie a specific enum to a particular function

lunar python
#

I mean if its card effect, it only affect one of the two player right?

hard viper
#

i already sketched out a solution for him a while back

#

abstract class was my main recommendation

#

he did not like the idea of defining 120 different classes

lunar python
#

Action is a useful class

#

you can add functions to existing functions

hard viper
#

you still need a way to tie the delegate to the key/enum

lunar python
#

repeated actions on cards can be reduced to AddCard(), FindCard(), DestroyCard(), BanishCard()

#

most yugioh effects can be reduced to about 20-30 functions

#

they summon bunch of stuffs and do random things

lean sail
#

only thing that matters is how this affects the users experience

lunar python
#

why must we have key and enum

#

like Dictionary?

Hi guys I have a moving platform and I want the player to move alongside the platform.

To achieve this, I parent/unparent the player to the platform.

However, and here's my question: When the platform is moving (XYZ) the character controller and camera are rather "janky" and dont' move/flow smoothly they instead jitter with the platform.

Anything I should consider when trying to achieve a smooth look for this?

I was thinking, add the velocity of the object to the controller.Move() method

Spring Joints

nimble cairn
#

Thanks, due to the volatile nature of the spring joint bridge, I think this coupled with setting the parent of the player to the bridge itself

#

would solve the issue

west lotus
#

You dont parent when you set the velocity

nimble cairn
#

Oh, really?

west lotus
#

Have a externalVelocity variable in your character. Then in your update resolve it and add it to your move after you have calculated player input. Then add the end of the frame 0 it out.

#

This away any number of objects can add do this external velocity during the frame

nimble cairn
#

Sweet as, sounds like a plan

#

@west lotus Works like a charm, thanks!

How would I go about copying the angular velocity and velocity of one rb2d to another? I can use addforce for the velocity but with addtorque the pivot point is different

first.velocity = second.velocity
first.angularVelocity = second.angularVelocity

Hey guys.
How can i make a good RIGIDBODY fps player controller, that can go up slopes and terrain?

I have a limitation have however:
-i need other forces to take effect on player, such as explosions and etc for rocket jumping, so i can NOT directly set velocity to player input.

#

Any good guides for this out there that go over how to handle slopes and terrain? When normally rb charachter controllers bump into slopes and then get launched off of them.

#

Remember, i need to have rocket jumping so I CANNOT CLAMP OR DIRECTLY SET THE VELOCITY ON ANY OF THE AXIS

vagrant blade
#

I'm sure you can find tutorials online for this. You have to add forces along the slope of the ground below the character, not directly forward like most people do.

next salmon
#

I said i want external forces to move my player around

hard viper
#

KCC respects collisions

#

do you mean you want to actually use .AddForce

#

which can be easily simulated on a kinematic body

next salmon
next salmon
#

Do i need to calculate the velocity and drag myself?

hard viper
#

the whole point of KCC is to make a kinematic RB move in 3D while respecting collisions vs static and kinematic rigidbodies

hard viper
#

but depending on 2D or 3D changes when the velocity += is evaluated.

next salmon
#

dosnt the fact that this is kinematic mean it can push physics objects of any mass without being slowed down?

hard viper
#

KCC is more like a custom physics solver

next salmon
#

But i dont want my 40kg player to be able to push a 1000kg rotating gate

hard viper
#

I made my own physics engine similar to KCC for 2D. It took me 3 months, and I’m already very comfortable with all the math. You do not want to make your own engine.

hard viper
#

just look at the main video for it

next salmon
#

So it will all be nornal? No weird interactions with physics objects? Its all be done beforehand?

#

I just need to implement addforce?

hard viper
#

just look at what it does

next salmon
#

Yooo this is amazing. It even has stairs and steps implemented

#

I wont need to clip stairs with slopes!

#

I cant believe its free

hard viper
#

KCC is like its own mini physics engine

#

it does require your own implementation. it’s like a separate rigidbody-like API

#

like you need to tell the KCC where to walk etc, but most of the slopes/stairs/collision/etc is what you are getting in the package.

#

it has a big document on how it works in detail

next salmon
#

Thank you 🙏

i want to check if the var is set or still empty, but VS doesnt let me do a null check, why ?

of course you can set a struct int member to have a default value of 5

to the int var but as the int var is part of the struct to that as well

is this permited ?

round violet
#

well now VS tells me that I cant access my struct members

    }

         sceneLoadCallback();

heady iris
#

When you yield an IEnumerator from a coroutine method, Unity will repeatedly call MoveNext() on the enumerator you yielded until it's exhausted

round violet
#

im returning the yield return of a inner coroutine

heady iris
#

then it'll go back to calling MoveNext() on the original enumerator

heady iris
#

This is a close recreation of how you'd usually write async code

#

which I think is a lot easier to parse than Callback Hell

round violet
#

is it because its already in a coroutine ?

heady iris
#

Hm, I'm actually not sure! I think the outcome will be the same..

#

StartCoroutine returns a Coroutine object

round violet
#

i'll keep my start method in case

heady iris
#

The StartCoroutine method returns upon the first yield return, however you can yield the result, which waits until the coroutine has finished execution. There is no guarantee coroutines end in the same order they started, even if they finish in the same frame.

#

now I need to check if yielding an IEnumerator does what I think it does

#

(i.e. the same thing as yielding a coroutine object)

#

excellent, it does

round violet
#

great

heady iris
#

I'm not sure if they're absolutely identical behind the scenes

#

there's certainly a huge difference if you don't yield the object

# 
IEnumerator Foo() {
  StartCoroutine(Bar());
  Debug.Log("Hi");
}

IEnumerator Bar() {
  yield return new WaitForSeconds(1f);
  Debug.Log("Hi again");
}
#

This immediately prints "Hi", then prints "Hi again" after one second

# 
IEnumerator Foo() {
  Bar();
  Debug.Log("Hi");
}

IEnumerator Bar() {
  yield return new WaitForSeconds(1f);
  Debug.Log("Hi again");
}
#

This prints "Hi" immediately and does nothing else

# 
IEnumerator Foo() {
  yield return StartCoroutine(Bar());
  Debug.Log("Hi");
}

IEnumerator Bar() {
  yield return new WaitForSeconds(1f);
  Debug.Log("Hi again");
}
#

This prints "Hi again" after one second, followed immediately by "Hi"

round violet
#

for all examples, you are doing StartCoroutine(Foo()) right ?

heady iris
#

Correct.

#

If I just ran Foo(), then the outcomes would be...

heady iris
heady iris
heady iris
round violet
heady iris
#

An IEnumerator-returning method executes until it hits a yield and then stops

#

If you don't call MoveNext() on the resulting IEnumerator object, it will do nothing more

#

because it's patiently waiting for you to ask for more values!

round violet
#

so using StartCoroutine makes it automatically call MoveNext ?

heady iris
#

I think it's useful to understand exactly how enumerators work. It takes away a lot of the "magic" from Unity coroutines.

heady iris
round violet
#

yes it is intersting

heady iris
#

When you call it, the IEnumerator is stuck into a list, and every frame (by default), every enumerator in the list gets MoveNext() called on it

round violet
heady iris
#

okay, yeah, it is on MonoBehaviour

heady iris
round violet
#

without starting a coroutine, when calling a IEnumertor, it will stop at the first yield return, and wont try again (thats when you use MoveNext)

heady iris
# 
IEnumerator DoStuff() {
  while (true) {
    Debug.Log("Doing work");
    yield return null;
  }
}
#

This runs twice on the frame that you start it

round violet
#

thats why sometimes i was seeing some errors at MoveNext, i was wondering what was this method i didnt write

heady iris
#

It hits Debug.Log once as it starts executing

#

then it yields and DoStuff() returns an IEnumerator

#

then Unity calls MoveNext on it in the same frame

round violet
#

unity calls once MoveNext ?

heady iris
#

It calls MoveNext every frame, unless you yield something like WaitForSeconds

round violet
#

without starting a coroutine ?

#

im confused now

heady iris
#

no, I'm talking about when you run StartCoroutine(DoStuff())

#

also, uh oh, I'm double-checking and I might be wrong here 🫠

#

one moment

heady iris
#

I was expecting to see two "Doing work on 86" messages in the console.

#

(frame 86, that is)

#

The first message comes from where we actually called DoStuff(); the rest come from Unity's coroutine logic

image.png image.png
round violet
#

okay ty

heady iris
#

...uh oh, am i wrong about something else here, too

round violet
#

now it way more clear

heady iris
#

today is a learning experience

round violet
#

:(

heady iris
#

Initially, the enumerator is positioned before the first element in the collection. You must call the MoveNext method to advance the enumerator to the first element of the collection before reading the value of Current; otherwise, Current is undefined.

Ooooooooooooooohhh

#

So I was wrong all along. When you run a method that returns IEnumerator, nothing happens.

#

StartCoroutine immediately calls MoveNext()

#

That's why I thought it ran up until the first yield statement.

#

Shoot. That's embarrassing

#

Well, at lesat I know now!

round violet
#

from memory, when i forget to add StartCoroutine, nothing happened.
thats why i thought it was weird

heady iris
round violet
#

so i have to keep my yield return StartCoroutine(...);

heady iris
#

the punchline: you can do it either way

#

you're yielding a value to Unity here

#

if it sees you yielding an IEnumerator, it will start working its way through that enumerator

#

if it sees you yielding a Coroutine, it will wait until that coroutine is done

heady iris
#

or if it's just equivalent to...

# 
IEnumerator enumerator = InnerMethod();

while (enumerator.MoveNext())
  yield return enumerator.Current;
#

That's something worth looking into
