Also, a memory free isn't dramatic here & there, but as mentioned, if you do that too often, it's just not properly optimized. The thing is that you have an alternative which is way more memory friendly & more efficient, if you want to go with the parsing method, that's up to you

teal viper
#

I'd like to see a game engine without a garbage collector or a similar system.

devout flume
#

But this probablt involves at least an O(n) time complexity, alongside other factors that consume unnecessarily

devout flume
#

It would be addressed to advanced programmers, or even studios

#

Which in terms mean they would need to charge a lot of money for it to be sustainable

teal viper
#

It's not as much about "knowing" how to manage memory. Some complex systems simply can't function without sort of a garbage collector.

timber tide
#

people actually destroy their objects?

devout flume
#

I agree, it would be great to have an option to fully manage memory

#

Biggest problem for unity is that GC isnt generational

night raptor
#

One nice thing about cargabe collector is that the workload can be divided between multiple frames which unitys garbage collector does so you don't need to worry that much about performance even if you dispose of large amount of data at once

languid spire
#

Even more important, the vast majority of programmers are totally incompetent and so systems like garbage collection are a requirement to protect their users from crappy code

#

I've got a few scenes that are identical except for the types of enemy waves that are spawned. I know I can have all this data be in one scene but I'm not sure what method to use. For this type of data loading, would that be done with scriptable objects?

languid spire
night raptor
#

relative to the amount of objects in the heap would sound reasonable though

Hi everyone! I’m a beginner working with prefabs, and I’m running into some issues with maintaining references in my Unity project. I have a car prefab that I spawn at runtime, and it needs to be assigned to the camera, but the reference to the car is lost every time I spawn it. Right now, I’m using FindObjectWithTag in Update() to re-assign it to the camera, but I know this might not be the best approach. The car also has button references for touchscreen movement (forward and backward), and because it’s a prefab, these references in the inspector are empty. I know I could assign them with a script, but it seems like it could get overly complex. Is there a recommended way to handle these references efficiently without a large script? Thanks!

rich adder
#

whatever is in the scene already had reference to camera, when you spawn you pass the reference

Let me explain like this, for example, there are ui buttons which i use to move the car forward ,backward , left and right. All these buttons are assigned to player movement script which is on the car. As i am making a multiplayer game, i need to make prefab of this car and spawn it when player starts the match. So i made a prefab of this car . And when the match starts and the car spawns, all the buttons which i assigned are going away, like its showing none in the inspector. I dont want them gone...

#

it's [SerializeField] , not [Serialize] - though it's not needed for public fields

wintry quarry
#

Only serializable types can be serialized.

#

Primitive data types (int, float, double, bool, string, etc.)
Enum types (32 bits or smaller)
Fixed-size buffers
Unity built-in types, for example, Vector2, Vector3, Rect, Matrix4x4, Color, AnimationCurve
Custom structs with the Serializable attribute
References to objects that derive from UnityEngine.Object
Custom classes with the Serializable attribute. (Refer to Serialization of custom classes).
An array of a field type mentioned above
A List<T> of a field type mentioned above

sleek notch
#

Okay thanks

timber tide
#

Ya also don't need to initialize it with new

swift sedge
#

in modern C# you can use a primary constructor and do List<Emails> everyEmail = []

slender nymph
wintry quarry
#

List<Emails> everyEmail = new(); works just fine

slender nymph
#

or in this case, no constructor call is needed as Mao pointed out since the list is serialized by unity so an instance is automatically created

timber tide
#

man I made so much fun at c# about the syntax of the full initialization, then the next week they released the version for the short version

#

was like 2015 or something? Surprised it took them that long

swift sedge
timber tide
#

of course if you wanted to downcast it you would have to type out the full syntax of it

languid spire
#

syntactic sugar, there are so many other, important, things that the devs could be concentrating their energies on

Guys i got the multiplayer working with photon fusion. Everything is working well. But the car movement is not smooth. Its a bit jittery. Can anyone please tell me how to fix it. Thanks in advance

slender nymph
#

#archived-networking
also photon has its own server you can ask for help with their networking tools in
and networking is not for beginners. you will fail if you don't actually understand what you are doing

red harbor
#

I followed their guide to make the player movement smooth but it isn't working. Guess I'll have to post this on networking

you would be better off asking in the actual photon server. and post actual details

#

why would be issue destroying

molten dock
#

thinking it may be laggy to destroy 200-500 ish objects in a short period

rich adder
#

are you just assuming that or you actually tested this

#

when you set to Destroy it doesn't even do it right away, it waits till the GC is coming to collect

swift sedge
#

DestroyImmediate is a solution, but not recommended

rich adder
#

thats meant for assets not instances

swift sedge
#

but in the docs, it has a second parameter called "allowDestroyAssets"

rich adder
#

idk I only used it in the Editor which from what i know , should only be used in that context

#

like destroying maybe TEMP objects created in Editor

#

idk what the bool is for tbh my assumption is was for that by default

Unfortunately no, I was gonna reformat but here it is.

Hello. I'm trying to display a crosshair and item name when my raycast hits a 3D object. I'm using a UI Image and a TMP_Text. Pretty much everything I have that's relevant has been up in the video below.

The Bug: When I look at an interactable object for the first time and my HUD displays, there is a jitter or jump in the camera. It only happens the first time the TMP_Text is drawn on the HUD.

Note: Sometimes the jitter or jump is larger than other times. Sorry if the issue seems super obvious, please pardon my incompetence. Also, in the video I had no idea why it was happening but have since figured out it's related to making the TMP_Text visible for the first time.

Video: https://www.youtube.com/watch?v=YulfGxssvJ8
PlayerInteraction.cs: https://pastebin.com/gyeYX9eR
Interactable.cs: https://pastebin.com/aJYh3kgM

Info & what I've found:
If it matters my player's movement is done in FixedUpdate() while my input is handled in Update().
I tried changing the PlayerInteraction for CheckForInteractable() to FixedUpdate but that did nothing, so I reverted it back to Update().
It's specifically when the line 48 of the 'PlayerInteraction.cs' runs. Why drawing the TMP_Text for the first time is causing a stutter? I have no idea and I'm not sure where to continue this debugging process. I confirmed it doesn't do this by commenting this line out which seems to fix the problem. There may still be a tiny stutter without it, but if so it's nearly unnoticeable. Could just be placebo for me looking for a stutter.

Hello, guys! So, I would like to know if there is a method in Unity that loops a clip infinitely. What I mean is that I don't want the clip to reset at the end in the loop of the clip but to infinitely being played over and over? I don't mean that loop because that checkbox is resetting the clip at the end of it's duration.

When the player dies a scene should load with a username text promting user to input a name. but should also be able to press play or quit too. this menu should looks the same as the startmenu except the text input thing. Is it better to have two different scences for that or have a deactivated element in the startscene and use same scene for gameover scene but with a logic saying if <player has died in gamescence> activate this gameObject. Which is the best?

Does anyone know what are the names of the CONTEXT menu elements for every component? Like rectTransform in this case.
If there is a full list somewhere it would be great tho, but for know I only need to know how is the inputMap assets from the inputManager package called.
[MenuItem("CONTEXT/RectTransform/Action", priority = 1)]

Hello, I'm just now starting to use Unity to make my first ever game, and I was wondering if anyone here could show me how I could add a border to my 2D game? Currently, if I set the RigidBody 2D's Gravity Scale to anything over 0, the character just falls from the map. so I would like to add borders so that I can add gravity to my game.

you would just arrange them to be at the bounds of what ur camera is seeing..

#

and so on..

vast hamlet
#

Ah, got it

#

Could somebody explain to me how exactly I should set the box collider where the character wouldn't "hang" onto it, but instead just step on it?

np, it won't take too long . . .

#

is there a simple coroutine class with OnCompleted callback in unity?

#

i want to have a list of coroutines and maybe end them before they finish

cosmic dagger
rocky canyon
#

you could probably make a custom class to handle it

undone pier
#

ye just asking quickly

cosmic dagger
#

or pass in a callback, or check a bool variable that can change outside of the coroutine . . .

rocky canyon
# 
    var myCoroutine = coroutineHandle.StartTrackedCoroutine(MyRoutine(), 
            onCompleted: () => Debug.Log("Routine Completed!"), 
            onCanceled: () => Debug.Log("Routine Canceled!"));```

#

thanks both of u

rocky canyon
#

good luck.. would be a cool helper class to keep for later

vast hamlet
rocky canyon
#

if those are both 2D colliders it shouldnt be doing what ur video shows it do

#

unless ur movement code is bad..

cosmic dagger
#

that's how i ended up creating a timer class with a bunch of actions, like: onCompleted, onCancelled, onSuspended, onResumed, onUpdated, onRestarted . . .

vast hamlet
# 
using UnityEngine;

public class MainCharacter : MonoBehaviour
{
    public FixedJoystick joystick;
    public float moveSpeed;

    float hInput;
    void Start()
    {
        
    }

    void Update()
    {
        
    }


    void FixedUpdate()
    {
        hInput = joystick.Horizontal * moveSpeed;


        transform.Translate(hInput, 0, 0);
    }
}
#

This is my movement code (I haven't added vertical functionality as I'll be adding a jump button)[

rocky canyon
# 
        public TrackedCoroutine(MonoBehaviour owner, IEnumerator routine, Action onCompleted, Action onCanceled)
        {
            this.owner = owner;
            this.routine = routine;
            this.onCompleted = onCompleted;
            this.onCanceled = onCanceled;
        }``` something like this eh?
rocky canyon
#

given enough transformation it can literally clip/ phase right thru ur collider

#

must use Rigidbody2D and accurate physics functions (for the best collision detection)

vast hamlet
#

Could you recommend me a guide for that?

the monobehaviour / coroutine relationship makes it pretty difficult in my eyes

#

i could build it... but do i completely understand it..

#

^ thats the dilemma

cosmic dagger
# rocky canyon i could build it... but do i completely understand it..

that's the truth. it's best to isolate/work on it in a separate project. then you won't have any other distractions. just make a simple coroutine that counts to 10 every second or display a log after a certain time. then you can mess with the calling onComplete to check that it finished, onCancelled if it was cancelled manually, etc . . .

#

break a feature down into task, and complete each step at a time . . .

rocky canyon
#

i'll give it a shot

#

learning experiene if anything

cosmic dagger
#

that's why i attempted to create my own pooling system, so i can understand how they work and to be able to add custom features. of course, this was before unity decided to make their own, but it's good practice . . .

rocky canyon
#

ya, imma try.. if anything its events, actions, callbacks

#

all that stuff that im a bit uneasy about

cosmic dagger
#

that's the part of practicing most people don't do. it's hard to learn something (a concept) if you don't attempt it yourself . . .

#

to me its more complicated b/c of how similar they all are

silk night
#

Idk if its just selective bias but I suddenly see many people using [field: SerializeField] instead of just [SerializeField], is there any difference or just syntax sugar?

rocky canyon
#

im 100% sure theres a difference in the two.. (soo more than just syntax sugar) specifcally? idk yet

silk night
rocky canyon
#

i think [SerializeField] is unity specific... and the other one is not.. and can be used to serilize backing fields of auto-implemented properties

backing fields? no clue lol but yea..

  • [SerializeField] for private fields you want to edit in the Inspector
  • [field: SerializeField] for auto-properties when you need Inspector visibility with encapsulated access

a sprinkle of complication

rocky canyon
#

hell ya 💪

#

good to know tho.. when i actually do start using more properties

timber tide
#

allows you serialize auto properties

#

such that you can make it a private setter, public getter

swift sedge
#

unity has a lot of attributes, so it's nice that it's still the same attribute name

timber tide
#

ye, and for all attributes if it's being applied to the auto property field you need to continue to use [field: ...] on it all

# 
[field: Header("Settings")]```

Is this a good way to check if player is holding mouse over a location in a grid in unity ?

When the mouse is clicked, see which square in the grid its in and keep checking if its still inside that square
And have a coroutine to have a hold timer.

#

I just checked out the hold interaction using the unity input system, however I need a way to be able to control how long the hold is depending on the type of object the mouse is hovering over.

rocky canyon
#

sounds like rolling ur own solution would be best if it were gameobject dependent

not sure tbh

but now, i would like to get those things converted to text elements and such,
So i can change / look at them when i hit play

#

Yes correct

#

I want it in the scene, it’s visible in the editor indeed

eternal needle

#

Make a ui object reference the scriptable object and simply populate the text/label. I'm unsure if you'll be able to change the asset:scriptable-object permenantly during runtime release but you could probably write/send the updated data back to the Google sheets ect.

Can someone please explain to me how this code works. It's baffling me. It's meant to go with the new input system.

Vector2 inputVector = playerInputActions.Player.Move.ReadValue<Vector2>();

Whereas before, I had to write all that

Vector2 playerDirection = new Vector2(0,0);

    if(Input.GetKey(KeyCode.W)) {
        playerDirection.y = +1; 
    }
    if(Input.GetKey(KeyCode.S)) {
        playerDirection.y = -1; 
    }
    if(Input.GetKey(KeyCode.A)) {
        playerDirection.x = -1; 
    }
    if(Input.GetKey(KeyCode.D)) {
        playerDirection.x = +1; 
    }

Like how does it know to just ReadValue and understand -1 or +1 for this Direction. Insane

Few thing here, considering using TryGetComponent as that's less error prone and easier to debug against

Oh and btw destroy has a time argument, like Destroy(gameObject, 0.1f)

First thing to do is figure if it's a code issue and I'd make sure the component that being retrieved correctly, otherwise could just be not set correctly on the editor.

Oh yeah right you apply the force to the rigidbody of the sphere, not the player

Also you can put a Script on c, which references the rigidbody in a public property, which you can then get off that script

timber tide
#

But if you're doing a cast using Overlapsphere, you should be getting the object with the collider, so if you're saying the parent of c is th eone with the rigidbody then it also must have a collider

It has a collider but it's deactivated because it's a container

I want an enemy in my game to shoot a bullet and then run a certain distance away from the player before shooting another shot

timber tide
#

That's just logic then. Assuming your enemy is patroling via path calculations, you want some sort of detection method like OverlapSphere to hault the current pathing. Then, calculate a new pathing towards the player.

#

If enemy is atleast 5 units close to the player -> shoot
else continue pathing

#

If enemy shot a bullet, find a position on the navmesh 5 units away from the player and path there

silver basin
timber tide

#

Sometimes you may not get a position, so the idea is to fallback on a count of sampling. If you can't find one then that's up to you to decide how they should behave.

#

Lot of ways about this, such as having nodes on your scene you consider as cover which you can just use those as the position

Howdy there,
I'm looking to create a timer that will work with a collider area and track how long the player has been in that area. If they're in that area too long, it calls a function. When they leave the area, the timer stops.
Can anyone please help?

# 
        uI_Fade.FadeToPurple();
        if(Time.deltaTime == timeUntilPoison) {
            playerHealth.Death();
        }
    }
    
    void OnTriggerExit2D(Collider2D other) {
        uI_Fade.FadeToClear();
    } ```
#

This is what I currently have but I feel like the if() is a little off.

is there any equivalent to a raycast that just makes a sphere with a specified radius around a transform, and checks if anything collides with that sphere?

slender nymph

#

@wraith phoenix Just a tip: instead of separate methods to fade for every color, make one FadeTo method with Color as a parameter . . .

#

Just check/compare its position with the world position . . .

timber tide
gleaming kraken
# timber tide OverlapSphere

thank you! I did it in a very stupid way by just making a sphere trigger, and adding anything that enters it to an array and anything that leaves is removed from the array, but this is so much easier and i'd bet much more performant too.

cosmic dagger
#

There is a distance method to see how close the GameObject is to a position . . .

timber tide

#

if the gameobjects have a collider then a physics query like an overlapcircle would

wraith phoenix
timber tide
#

Mind you that rigidbody is only required to register the events, but can be set as kinematic

#

some physx bs

wraith phoenix
gleaming kraken
#

because colliders just aren't enough i guess

#

blame nividia

#

meanwhile box2D allows you to invoke colliders directly

timber tide
gleaming kraken

timber tide
#

box2D you can just check if something is intersecting via collider

#

instead of having to use these events

wraith phoenix
gleaming kraken
slender nymph
#

you can check if something specific is touching the collider with the IsTouching method, but the methods like Collider2D.Overlap still require a rigidbody

gleaming kraken
#

unless you're talking about couroutines

timber tide
wraith phoenix
wraith phoenix
slender nymph
timber tide
#

Oh, I mean having to use the Trigger method specifically

#

Sorry yeah rigidbody is still required unfortunately

slender nymph
timber tide
#

It's just that I've a preference of doing stuff in Update primarily, so I'm not the biggest fan of just the general usage of OnTrigger() ect

#

so usually you fall back onto using the physic queries but it's something easily to work with on the editor visibly

#

Maybe I'll look into developing a small gizmos script per query for that specific gameobject

wraith phoenix
#

I did get some of the code to work.

# 
        if (other.CompareTag("Player")) {
            Debug.Log("Player tag has worked with collider");
            poisonTime = timeUntilPoisoned;
        }
    }

    void OnTriggerStay2D(Collider2D other) {
        if (other.CompareTag("Player")) {
            Debug.Log("Player has entered Poison");
            uI_Fade.FadeToPurple();
            poisonTime -= Time.deltaTime; 

            if (poisonTime <= 0) {
                Debug.Log("Poison time has reached zero and if statement fired");
                playerHealth.Death();
            }
        }
    }

    void OnTriggerExit2D(Collider2D other) {
        if (other.CompareTag("Player")) {
            uI_Fade.FadeToClear();
        }
    }```
#

My uI_fade is not wokring but the poison area kills me after 3 seconds

slender nymph
#

depending on what your FadeToPurple method actually does, you might be restarting the process over and over

wraith phoenix
#

I likely need to move it to OnTriggerEnter

# 
        if (fadeRoutine != null){
            StopCoroutine(fadeRoutine);
        }

        fadeRoutine = PoisonFadeRoutine(1);
        StartCoroutine(fadeRoutine);
    }

private IEnumerator PoisonFadeRoutine(float targetAlpha){
        while (!Mathf.Approximately(poisonFadeScreen.color.a, targetAlpha)){
            float alpha = Mathf.MoveTowards(poisonFadeScreen.color.a, targetAlpha, fadeSpeed * Time.deltaTime);
            fadeScreen.color = new Color(poisonFadeScreen.color.r, poisonFadeScreen.color.g, poisonFadeScreen.color.b, alpha);
            yield return null;
        }
    }
#

Here is my fade FadeToPurple method

not sure why it isn't firing

I'm encountering the weirdest thing I have ever seen. I'm creating a new empty scene, add an empty GameObject and add the following script:

public class AuthManager : MonoBehavior
{
  public static AuthManager Instance { get; private set; }
  // some other fields
   [SerializeField] private string baseUrl = "http://localhost:8000/api";
  // etc. (but nothing special)
  private void Awake()
      {
          Debug.Log($"AuthManager Awake called. {Instance == null}");
          // Implement Singleton pattern
          if (Instance == null)
          {
              Instance = this;
              DontDestroyOnLoad(this.gameObject);
          }
          else
          {
              Debug.Log("Duplicate AuthManager detected. Destroying.");
              Destroy(gameObject);
              return;
          }
  
          DontDestroyOnLoad(this.gameObject);
      }
  }

The gameObject get's destroyed after seing AuthManager Awake called. True in the console. And there is no Duplicate AuthManager detected. Destroying in the console either. It makes zero sense to me.

    // some other fields
    [SerializeField] private string baseUrl = "http://localhost:8000/api";
    // etc. (but nothing special)
    private void Awake()
    {
        Debug.Log($"AuthManager Awake called. {Instance == null}");
        // Implement Singleton pattern
        if (Instance == null)
        {
            Instance = this;
            DontDestroyOnLoad(this.gameObject);
        }
        else
        {
            Debug.Log("Duplicate AuthManager detected. Destroying.");
            Destroy(gameObject);
            return;
        }
  
        DontDestroyOnLoad(this.gameObject);
    }

    public void Start()
    {
        Debug.Log("Start called.");
    }
}

Could I be doing something else wrong?

your text object is very likely a TextMeshProUGUI object, not a legacy Text object

night raptor
#

past spindle
#

I'm using Text in another script and it works fine. Why would it be different here?

hexed terrace
#

because you're using legacy text component with it..

polar acorn
#

Is that other script referencing an actual Text object instead of a TextMeshProUGUI object?

#

They're different components

#

They aren't interchangeable. You can't use a variable of one type to reference the other, in either direction

#

Show the inspector for the object that does work, and the one for the one that doesn't

there are beginner c# courses pinned in this channel, if you are not aware of the + operator, then perhaps start there

how do i change the material of an object thru a script? like if i want to change a ball to use a different texture by pressing a button

slender nymph
gentle fog
slender nymph
#

text mesh pro had nothing to do with converting the numbers to a string. its text property is a string and can only have a string assigned to it.

raw loom
slender nymph
#

you can change the entire material with that property

raw loom
#

oh i see

slender nymph
#

the code example is merely just an example of getting the material. that is not the only thing you can do with it

polar acorn
past spindle
#

For changing a variable in another script, you gotta declare the variable, define it in start, and do the math your wanting to do, but what sends the data back to the script you got the variable from in the first place?

polar acorn
#

That doesn't seem like what you do for changing a variable

steep rose
#

you have to reference the script if which containts the variable you want to change then change that variable like so
public Script _Script;, _Script.Var1 = etc;

past spindle
#

Then I’m doing it wrong lol

#

You don't get a reference to a variable

you get a reference to the object that has the variable

I wanna make a cue which can rotate as it moves around the ball, where can I start?

#

I tried the lookat method but it rotated it in axis' i didn't want

rich adder
#

You could also potentially give it a parent object whos origin is always at the ball when shooting, and use regular rotate methods

dreamy bear
night raptor
#

Parenting would also make it easier to make the shooting animation etc. because you could just move on local axes

carmine sierra
#

Is it?

rich adder
# carmine sierra Is it?

nahh not at all . SetParent function works very well , just move the pivot item to the ball when you setup for a shot

night raptor
carmine sierra
#

I need to rotate it around the ball

rich adder
carmine sierra
#

so i make the pivot a child of the ball?

rich adder
#

no because if you move the ball everything will follow the ball, all you need is to set that parent position to the ball

carmine sierra
rich adder
carmine sierra
#

ohh

#

couldnt i just make the cue a child of the pivot though

#

the ball i mean

rich adder
#

you could but after you hit the ball you must unparent it

#

otherwise any child (including the cue) will follow the ball

carmine sierra
#

oh ok

carmine sierra
#

i have the pivots position and the cues position (where it follows the mouse)

rich adder
carmine sierra
#

yeah i get that

#

but idk how the cue will understand what angle to point in

#

cause it will rotate with the mouses position

#

i assume i need to take the distance between the two and do smth but idk what it is

dreamy bear
#

You want to target where the mouse is pointing ?

rich adder
#

that depends on how you plan on rotating , its behaviour

carmine sierra
#

at the cue balls position

rich adder
#

the pivot will be your rotation

carmine sierra
#

yeah

#

but the mouse will move to change the rotation

rich adder
#

usually transorm.up is your direction

#

you could rotate the Z with for example the delta of the mouseX

If I don't indicate a parent when defining a class, does it automatically have Object be the parent?

make sure its in Local mode not Global

yes you want transform.forward if thats Local mode

#

cast the mouse onto a plane here (if you're doing topdown)

        if (Physics.Raycast(ray, out RaycastHit raycastHit)) {
            _mousePos = transform.position = new Vector3(raycastHit.point.x, 0, raycastHit.point.z);
        }```
#

I did that

rich adder
#

so based on that example I sent, it would be
var dir = worldPoint - cuePivotTransform.position cuePivotTransform.forward = dir.normalized
just make sure the plane is in the correct axis

carmine sierra
#

yh

#

when it comes closer

did you use the plane?

no need for a reg raycast here, use the plane so its flat

fixing vs code not opening

teal viper

# waxen adder Yeah, I might look into that. I get the whole thing of them being a function in ...
  • Run some function when you click a button, or multiple functions
  • Detect if an actor gets damaged
  • Detect if the scene changes
  • Detect if a tween is complete
  • Detect if the editor's play state changes
  • Delay an editor action via EditorApplication.delayCall to call a function on the next editor frame

etc etc, many use cases where you basically want to "emit" an event for any number of "listeners" to get that emission later.

waxen adder
#

If I'm thinking in that particular area/scope, it makes more sense

#

Yes. Also bawsi was talking about the literal event keyword which can be put onto a delegate variable so only the thing that holds it can actually run it.

you could use FindGameObjectsWithTag

If there is no way around doing that by tags the answer above is your choice but thats generally not something you want to do

hexed terrace
#

Don't want to do it often.

Once at the start during/after load is fine

#

The question is too vague to give the best way for this situation though. There are too many ways to do this and the best way depends on the specific use case.

private void Update()

        // ... (Other code)

        Vector2 direction = lookAtObject.transform.position - transform.position;

        float lookDirection = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;

        transform.rotation = Quaternion.Euler(0, 0, lookDirection);

        spriteRenderer.flipY = transform.position.x > lookAtObject.transform.position.x;
}```

is this a clean way to implement an object looking at another object? (2D space)
timber tide
#

if it works it works

languid spire
gleaming kraken
#

or i might be using it wrong

#

by just putting in the object I want it to look at

#

rather than the look direction

timber tide
#

this is top-down?

#

as you're using atan2

#

funnily enough, you can use quaternion's methods too (z-up)

I used OverlapSphere to create a knockback effect, but it sends the player through the epicenter if they are running toward it instead of knocking them back. Recently ai was told player movement can override addforce and I was wondering if stopping the player movement prior to the addforce would fix that or if there was a simpler solution?

slender nymph
#

it depends on how you are moving the player. if you're using anything other than addforce to move them, then yes you will need to stop their movement ability for the duration of the knockback so you don't completely override it

We don't spoonfeed scripts here, I'm sure there are plenty of tutorials to achieve that, you may also want to check the documentation. I know for sure that in the beginner pathway on !learn, there is a final step that introduces you to scene management & scripted buttons to teleport from one scene to another

that's your issue

You need to give your object a Rigidbody if it doesn't have one, turn on interpolation, and move it in FixedUpdate with Rigidbody.MovePosition

So this is my Loader class. I want to go to Loading Screen first. Then when on Loading Screen scene, after first update, it fires the callback saying the scene is loaded. Then I want to load the scene name I pass in additively so i do not destroy my Init scene which is loaded from the start of my game. For some reason when I press load. It loads Loading screen scene and playable scene again and again.

as he's got no font asset assigned, I'd assume it's imported with the essentials

you need to generate a font using the TMP font generation tool

you don't need to generate a font to use TMP. they have a default . . .

There's no font assigned here by default.
They get no font asset in the drop down, because none are present.
The default font isn't present because they haven't imported the TMP essentials

There are a lot of ways to pass information between objects, which strategy you want to go for really depends on what you're trying to do. Take a look at singletons. You can only have one instance of a Singleton, so you'll have a static method for accessing that instance. Let's say you want to track score in such a way that any object can read or modify the score, you could have a ScoreManager singleton with a score int, then if you want to add 100 points to the score from any script, you'd just do something like ScoreManager.Instance.addPoints(100);

transform.position - c.transform.position * -1 is the same as transform.position + c.transform.position

If you want to reverse the direction, swap the positions: (c.transform.position - transform.position).normalized

When I load a scene additively while im still on the say loading screen. The additively loaded scene's awake methods will get called right?

It will do whatever you told it to do in Awake

if that includes "looking for objects", certainly.

final kestrel
#

Yeah like. I think my additively loaded scene looks for the camera object inside the loading scene.

#

Its possible yeah?

wintry quarry
#

if you wrote it that way

cosmic dagger
#

is that what you told it to do?

past spindle
#

Hey, that seems to have worked, reversing the positions. Thanks

wintry quarry
#

I do believe if you delay scene activation, you might be delaying Awake/OnEnable.

#

but it's not clear

final kestrel
#

I mean no I do not want it to be clear. I just want it to call awake if the scene is loaded but i guess i am not doing it. Because in my newly loaded scene, when it gets set active, even though I have a camera, it says camera is destroyed. I believe it is because awake gets called in my new scene while im still on the loading scene because of additive loading. Finds the loading scene camera, when the loading scene gets unloaded it loses the reference and never tries to find again

wintry quarry
#

sounds likely

#

You might need to evolve beyond whatever naive method you are currently using for finding the camera

final kestrel
#

Thats right. I need to evolve. Thanks for the help

#

Wohooo! I delayed the finding camera and it works.

I have this line off code, but it return null, if i restart the game, any idea why?

what do you mean by "restart the game"

you'd have to explain how you're doing that

and on which object this script lives, etc..

    }
}
#

and now the error appers, if the tirgger gets triggert. i seem like the logic is null, but why ?

slender nymph
#

if there is no exception being thrown in Start then whatever object is tagged with Logic does not have a LogicManagerScript component attached

queen adder
#

this is the whole game, the logic (gamecontainer) was the script

and i really don't understand why unity didn't find the logic script

make sure that is the only object tagged as Logic in your scene

Just to make sure, which one is better for the new Input System

Invoke C# Events or Send Messages...?

#

I mean right now I'm using Invoke C# Events and it works, but if I had to call my methods (when I make a state machine later), I don't think it's letting me do that

#

Well...I don't know how to call methods with Input CallbackContext as the parameter

zenith cypress
#

I just use the actions directly, so I don't use either.

normal turret
#

With the InputAction reference thingy...?

zenith cypress
#

You can assign actions to a variable in the inspector with InputActionReference. Then you can use the events yourself like .action.performed += MyEvent;. Otherwise if you are starting out, try out all the options to find a way that you think works best for yourself 😄

Yeah that's true, I'll test it out, thank you

yeah, like it disappears either once it scrolls into the image's border or before it

remote osprey

It needs to scroll upwards but also toward the image?

#

you can just change its visibility once it crosses the border

#

There's probably a doTween to make an animation for that

#

You'll need to make each line be a separate object

And each object has a trigger event or you can just coordinate the animation with DoTween to do what you want to do
