Take for example Pokémon and the way the player interacts with PCs, Pokémon Nurses...

frosty hound
#

I mean, is that what you're making though? A 2D tile based game?

ionic zephyr
frosty hound
#

Then really the player should just be "examining" the tile in front of them to see if there's anything on it, and handling the results. You don't necessarily need to do zones or anything.

#

But again, depends on your game. If you want an NPC to have a (!) above their head when you're near them, that would be a trigger zone, vs another way to detect the player is actually interacting with them

#

It's not a one size fits all solution, you need to clearly define how you want interactions to work in your game.

ionic zephyr
#

the ones you need to press a key

hazy fiber
#

when collision boundaries for 2 moving objects controlled by the player are set (where both objects cannot bypass these boundaries)
how can i let a third object bypass the same boundaries?

ionic zephyr
rocky canyon
ionic zephyr
#

that should be placed on the player, right?

frosty hound
#

Yes, the player is reponsible for deciding that they've checked for something in front of them

rocky canyon
#

if its raycast u should raycast from the player.. trigger and stuff could be on the interactable object.. but still makes more sense for the player

ionic zephyr
#

what is the most accurate method?

#

I usually use boxcollider2D

rocky canyon
#

i cant say for 2d.. osteel might know

frosty hound
#

You could overlap with any shape. If you want to use that, just make sure it's smaller than the size of a tile, so you're not overlapping two interactions.

#

To be clear, overlap here means using the OverlapBox / OverlapCircle functions and doing it in code. Not actually using a physical collider.

raw token
ionic zephyr
frosty hound
#

That question doesn't make sense

#

What are you worried about?

ionic zephyr
frosty hound
#

Both will work, there is no better

#

However, if you just have an actual object that is moving with the player, you will have to manage the triggers

#

If you check with code (overlap box or circle), you can control when you actually care to check, such as once the player finishes moving to the next tile.

Excellent 👌. How do you handle the click events?

fickle stump
#

when you click a marker, the content of that marker should be loaded, all other markers disabled.

#

What is that you're struggling with here?

fickle stump
#

Where do i start

willow scroll
#

By making them UnityEngine.UI.Buttons?

fickle stump
#

So, I'm struggling with the context. How do i make them buttons? What does the => mean, whats a listener ._.

willow scroll
#

Do you know what UI Buttons are in Unity?

#

Add a Button component to them

fickle stump
willow scroll
#

Then why are you asking how to make them buttons?

fickle stump
#

i just realised how you meant it

#

i thought there's a way to code them as buttons

#

but i know what UI Buttons are

#

as long as u mean these

image.png
willow scroll
#

There is a way to code them as buttons, but Unity already provides a built-in one

#

There is no graphic

#

Attach an image too

fickle stump
#

if I'm adding an image, doesnt it cover everything else? doesnt it make sense to not have them as buttons

image.png
#

i mean to not have them have images

willow scroll
#

And you don't have it separated by those images?

fickle stump
#

oaky so

willow scroll
#

This... is bad

rocky canyon
fickle stump
#

this is a bit complexe to explain

rocky canyon
#

and make it transparent

#

(invisible button over ur main image)

willow scroll
#

Well, you should first consider making this whole photo a UI Image

fickle stump
# willow scroll This... is bad

the image you see is a brochure with AR Elements, you're palcing the AR elements on that brochure so the image has to be loaded

fickle stump
#

tehcnically?

AR_ImageTarget

raw token
#

Can we just see a screenshot of a marker object's inspector? 😅

raw token
# fickle stump AR_ImageTarget

So you can still do what sashok was describing. The only difference is where your marker object script handles a "click" you'll have it invoke a custom event.

public event Action<MarkerScript> OnClick;

public void OnMouseButtonUp() {
  OnClick?.Invoke(this);
}

(or similar)

Then the manager can subscribe to this event

private void OnEnable() {
  foreach (MarkerScript marker in Markers) {
    marker.OnClick += HandleMarkerClicked
  }
}

private void OnDisable() {
  foreach (MarkerScript marker in Markers) {
    marker.OnClick -= HandleMarkerClicked
  }
}

void HandleMarkerClicked(MarkerScript marker) {
  // ...
}

You can also do all of this without events at all - give each marker a reference to the manager and have them call the method on the manager directly when "clicked". But the event pattern is a little cleaner, and events are a great tool to have in your toolbox

has this ever been solved.. I have a rigidbody that moves w/ offset from camera.. (camera is attached to CC)

#

no matter what combination of interpolation or changing around update loops and stuff i can't get all of the jitter out

#

its better but not perfect 😢

ionic zephyr
#

how can I keep objects static while still wanting them to be detected with overlapCircle??

slender nymph
#

they only need a collider for that

slender nymph
rocky canyon
#

overlap detects colliders not rigidbodies

rocky canyon
#

which is child of my CC

#

w/ physics forces.. 1 sec

ionic zephyr
#

what? then I dont know why it doesnt detect it without a Rigidbody

rocky canyon
# 
                // Apply lift force to counteract gravity
                Vector3 lift = direction * liftForce * Time.deltaTime;
                pickedObject.linearVelocity = new Vector3(pickedObject.linearVelocity.x, lift.y, pickedObject.linearVelocity.z);

                // Clamp the y position to ensure it does not exceed maxHeight
                Vector3 clampedPosition = pickedObject.position;
                clampedPosition.y = Mathf.Clamp(clampedPosition.y, 0, maxHeight);
                pickedObject.position = clampedPosition;

                // Update the target position
                targetPosition = followPosition;
            }```
ionic zephyr
rocky canyon
#

imma try late update

ionic zephyr
slender nymph
# ionic zephyr
  1. !code 👇
  2. prefer TryGetComponent over two separate GetComponent calls just for one of them to be a null check
  3. a rigidbody does not make it any more likely to be found using a physics query, the query will find colliders that don't have a rigidbody justfine

rocky canyon
#

i cant really tell a difference.. it might be a little better

ionic zephyr
rocky canyon
#

1 sec, i'll try fixedupdate now lol..

slender nymph
rocky canyon
ionic zephyr
#

this tryes to get a component of interaction

slender nymph
#

yes that was the only part of the code we could actually confirm the validity of

ionic zephyr
#

and then start a method which is in that component of other gameobject

#

which uses a UnityEvent

slender nymph
#

show 👏 the 👏 code 👏

rocky canyon
#

i give up, fixedupdate looks jittery too

#

guess i'll just not use a lift mechanic on my CC.. i'll instead reserve it for my Kinematic boi

ionic zephyr
#

one method gets to the other

#

the unity event is assigned in the editor

slender nymph
#

have you actually done anything to find out what was hit? because you aren't filtering any colliders out of the OverlapCircle which means if the overlapcircle finds literally anything else first then it has failed to find the Interactable object.
so i'd bet that it's not that it isn't working without a rigidbody, i'd bet that the rigidbody is just making it a higher priority so it isn't finding other objects first. you likely just need a layermask to ensure you are only detecting interactable objects with that query

ionic zephyr
#

Okay, lets try that

slender nymph
#

you're also doing literally nothing at all to ensure you are only calling TryGetComponent when anything was detected, so if nothing is detected you'll be receiving NullReferenceExceptions, and if you are not then the issue is 1000% what i said before

rocky canyon
#

whoop whoop! hell ya

#

just needed some fine-tuning of the forces

#

MUCH higher forces than i expected

#

and hella dampening to accompany it

#

and i changed the tracking to use RB.MovePos in fixedupdate @slender nymph so thanks for that too

Is it bad practice to use a static rather than constructor or does it depend on the scope of what you're trying to do?

#

@bold plover can you clarify?

#

you mean to call a static method (to create an instance) instead of that type's constructor?

Hello I am new and would like to create a VR app with hands that are detect through the camera for a project. Can you tell me how I could do and/or the steps to follow.Thanks

ionic zephyr
bold plover
#

Of course! Error CS0120. Trying to make it so that movement values in the main player script correlate with movement state. Wondering if it is better to declare that variable as static or define that object as part of a constructor argument.

Hoping that makes a bit more sense.

Alright. I wasn't certain if it was worth it as there are two listed solutions. I'm just not sure if one is "better" than the other.

How do I log positions? And detect if an object has gone past a certain position?

wintry quarry
ancient rampart
#

Just debug and transform.position?

wintry quarry
#

Debug.Log($"My position is {transform.position}");

ancient rampart
#

Ahh ok

wintry quarry
cosmic dagger
#

log the value(s) you want to track. that's up to you . . .

ancient rampart
#

Figured, just hadn’t done much with the position information in code, that was the main part I was wondering about, but if it’s just transform.position that’s pretty easy

wintry quarry
#

transform.position is the position of the object, yes

ancient rampart
#

Also meant moreso like

#

Logging it to a variable, or something I can check for another object

wintry quarry
#

the beauty of programming is everything is data

#

and you can do anything you want with it

ancient rampart
#

Like if object A is past object Bs Y position then do this

bold plover
wintry quarry
#

if (a < b) etc

bold plover
#

Been spending the last two days just reading about constructors and trying to get all the details under my belt.

ancient rampart
wintry quarry
#

in this example a and b are numerical values

ancient rampart
#

To compare 2 objects

wintry quarry
#

you don't compare objects

bold plover
#

At least I hope I understand said point as you intended, haha.

wintry quarry
ancient rampart
#

Cuz I need their individual transforms to compare

#

Yeah I have to reference them somehow

wintry quarry
#

you need references to the objects to get their positions, if that's what you're asking

mint remnant
#

is there a way to initialize a sprite to a source from code?
public Sprite sprite = new Sprite

polar acorn
wintry quarry
mint remnant
#

I guess so, when I drag an image in there it just shows a sprite

wintry quarry
#

What else are you expecting it to show

polar acorn
mint remnant
#

I was hoping to initialize it from code as it's in an array of them

#

to avoid having to drag alot

wintry quarry
polar acorn
wintry quarry
mint remnant
#

they are subelements of other arrays, so can't just drag a bunch like that

wintry quarry
#

then sure, just populate an array in code. You certainly wouldn't be doing that in a field initializer though

#

ever heard of a for loop?

hi this script is for a 3s countdown. in game it shows 3,1 and not 3,2,1 as it should i also tried it with higher countdowns and it skips for 2 numbers there too like for 6 : 6,4,2 ``` cs
public class ReviveScreen : MonoBehaviour
{
public GameLogic logic;
public Text CountdownText;
public int Countdown;

public void StartCountdown()
{
    StartCoroutine(CountdownS());
}
IEnumerator CountdownS()
{
    while (Countdown > 0)
    {
        CountdownText.text = Countdown.ToString();
        yield return new WaitForSeconds(1f);
        Countdown--;
    }
    yield return new WaitForSeconds(1f);
    logic.CountdownFin();
}

}

i debuglogged the countdown it showed what its supposed to show on screen 3,2,1,0

wintry quarry
#

where did you put the log

#

and when did it print

#

look at the timing of when it prints. Is it printing two numbers at once, then waiting 1s, then printing two numbers again?

polar acorn
#

It's pretty clear you're calling the coroutine twice. That's why I asked for the code of where you're calling it

wintry quarry

#

yeah it goes two numbers at a time

wintry quarry

ok so

case closed

stop running RevContinue twice

just changing that damage amount

could use an enum for ur tools

            case ToolType.Shovel:

# 
 public void TakeDamage(ToolType toolType)
    {
        float finalDamage = CalculateDamage(toolType);
        Health -= finalDamage;
    }
``` and im not sure what u mean by u dont want everything to be damaged.. u'd only have scripts on the things u want damaged..

the enum would look like

{
    Axe,
    Shovel,
    etc,
}```

the clearest reference is minecraft

rocky canyon
#

interfaces come to mind.. IDamageable.. (all it knows is that it can be damaged) and every thing u inherit from it could just have a Damage() function you call..

#

you'd still need different components.. but the logic would all be the same.. so u'd just have to check which tool is being used

public class Wall : MonoBeahviour, IDamageable

I was following the steps of the guy in this video and I encountered this error

anyone know why this script is instantly removing the platform instead of fading it out
(the fadetimer is a float and set to .25f)

because it's not a Coroutine

I'll try using a coroutine

it loops until it's done, all at once

#

Stop calling GameObjects “objects” in confuses me 😭

spiral glen
rich adder
#

kinda

#

everything in c# is an object essentially

half egret
#

You need to wait for the end of the frame while looping

rich adder
#

you are in a OOP(object oriented programming) language

rich adder
modest dust
spiral glen
#

oh

rich adder
#

without coroutine you would have to take out the while loop and only use time.deltaTime / timer

thorny basalt
#

Which is different from c# object iirc

rich adder
thorny basalt
#

Yes

#

Correct

alpine dew
#

Does anyone know how I could return the text property of a TMP component as a string array to be iterated over?

rich adder
#

not specific to GameObject though i meant

#

you make a class, thats an object (a blueprint to one actually)

thorny basalt
#

Yeah. Language for objects is kinda confusing since some beginners since I see some call GameObjects objects.

deft grail
thorny basalt
rich adder
alpine dew
#

let me just show you my code maybe it'll explain itself better

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

public class TextScroll : MonoBehaviour
{
    private string[] text;
    private float textSpeed = 0.01f;

    private TextMeshProUGUI textTMP;
    private int index = 0;

    void OnEnable()
    {
        textTMP = GetComponent<TextMeshProUGUI>();
        text = textTMP.text;
        textSpeed = GlobalVariables.textSpeed;
        ActivateText();
    }

    public void ActivateText()
    {
        StartCoroutine(AnimateText());
    }

    IEnumerator AnimateText()
    {
        for (int i = 0; i < text[index].Length + 1; i++)
        {
            textTMP.text = text[index].Substring(0, i);
            yield return new WaitForSeconds(textSpeed);
        }
    }
}
#

The intention is the script gets the TMP component of the GameObject, it loads up the text (I need it to be as an array type though I guess somehow), and it then iterates over the text for each character until the coroutine is done

#

but this current setup returns a null object reference

rich adder
#

are you doing some type of typewriter effect or whatever

alpine dew
#

text = textTMP.text; it says it cannot implicitly convert from a string to a string array string[]

alpine dew
rocky canyon
#

text is an array

#

how u gonna set a string to an array

polar acorn
rich adder
polar acorn
#

What are you trying to set text to? Which strings?

rich adder
#

its array of chars technically

#

but immutable

alpine dew
rich adder
#

if you want to iterate over the chars just iterate over the string, its already an array

polar acorn
thorny basalt
#

But why did you make it an array?

deft grail
thorny basalt
#

Oh wait misread sorry. 😅

alpine dew
#

that's just how the concept was set up by someone else and so it seemed like it needed to be an array to be iterated over by its index but I guess it being a string in general would allow that wouldn't it

#

I'll try some things

deft grail
rich adder
alpine dew
#

There was an attempt

rocky canyon
alpine dew
#

It's saying there's no substring method because it's per character

rocky canyon
#

substrings are easy to use

#

thats how my text writer wrks

modest dust
#

I believe you can also just use the property maxVisibleCharacters instead

spiral glen
# 
    [SerializeField] float fadeTimer = .25f;
    void Start(){
        color = GetComponent<SpriteRenderer>().color;
    }
    void OnTriggerEnter2D(Collider2D coll){
        if (coll.name == "Player"){
            StartCoroutine(Fade());
        }
    }

    IEnumerator Fade(){
        color.a = color.a - 0.1f;
        yield return new WaitForSeconds(fadeTimer);
    }```
I'm kinda lost in why this script isn't doing anything (I'm trying to make an object fade out if a player touches it)
deft grail
modest dust
rich adder
#

the manual literally has example for fading..

spiral glen
#

oh damn

rocky canyon
#

not sure why i never realized that Neat!

rich adder
# rocky canyon 🤯

the difference is they are Immutable so you cannot replace chars by index
reason why new strings needs to be made when modified

rocky canyon
#

ahh gotcha gotcha makes sense..

eternal needle
# rocky canyon

I think tmpro has a max visible characters field you can use instead of this also

rocky canyon
#

i see caesar also mentioned that.. ❤️

eternal needle
#

Oh my bad, I didnt see that

rocky canyon
#

me neither..

#

but im changin it aorund right now..

#

im all about TMP functionallity

alpine dew
#

Alright so I reworked it slightly and well it does work but it seems like the coroutine only iterates about 14 times and then just stops before the end of the text's length

#

actually it varies

rocky canyon
#

how??

alpine dew
#

I have no idea

polar acorn
eternal falconBOT
alpine dew
rocky canyon
#

if u use the same string each time, im not sure how it would ever vary lol the loop is the same

alpine dew
#

I'll show you the in-game result of what I mean

#

it only runs for so long and depending on the textspeed it stops early

polar acorn
#

And show what it logs

alpine dew
#

Will do

#

For some reason it just works as intended now after I decided to log it

#

before it would stop before the end of the string

#

now it finishes

#

no change

#

I think it just hates me ngl

#

but thank you guys

How do i get a variable from another skript. I looked so much online and can't find a solution

slender nymph
alpine dew
#

might be a little bit hacky because obviously scene names can change but that is one way to do it

jaunty bay
jaunty bay
rocky canyon
#

the gameObject part is redundant

alpine dew
#

basically I made a series of empty GameObjects and loaded up references to each in a script in every scene, and that script then switches based on an integer, and the integer determines which gameobject to transform the playercapsule to** **

#

depending on how you want to do it you can set the spawn position either as a value the function returns or maybe store it globally

timid quartz
#

is there a way to find out where the input axis is coming from? I have no peripherals plugged in beyond keyboard/mouse/headphones and for some reason my input axis is reporting .17 on the vertical scale.

You should have a class that extend dictionary for serialization.

#

Or buy odin inspector if you don’t want to write your own.

thorny basalt
#

If not you can make a list

eternal needle
#

but there are other better implementations online out there

thorny basalt
# 
[System.Serializable]
private struct DoorSpawnLocation
{
public Vector3 spawnLocation;
public Door spawnedDoor;
}
[SerializeFeild]
private List<DoorSpawnLocation> doorSpawns = new();
#

@jaunty bay if you are not doing lookup values just do this.

timid quartz
#

for some reason my movement code is snapping me to 0,0,0 - I have tried setting movement speed to 1 in the actual function and its still being funky.

    {
        // if we are holding a movement button, we want to move in that direction
        MovementSpeed = 1f;
        
        float horizontal = Input.GetAxis("Horizontal");
        float vertical = Input.GetAxis("Vertical");

        Vector3 location = transform.position + new Vector3(horizontal, 0f, vertical);

        rigidBody.MovePosition(location * MovementSpeed * Time.deltaTime);
    }```
#

both my horizontal and vertical axis are correctly 0 when this happens, too, I made sure of it

#

so with 0 it should just be moving me to my current location

#

instead I snap to 0,0,0

modest dust
#

You're constantly multiplying your whole position by delta time

timid quartz
#

OH!!!

modest dust
#

If anything, you should be only multiplying the position change

timid quartz
#

you're a genius and totally right

#

thank you

thorny basalt
#

Double check your math before doing stuff

#

Desmos is a cool tool for that

timid quartz
#

I refuse to use third party tools for anything!

#

(but seriously thank you, obvious in retrospect for sure!!)

modest dust
#

Does discord count as a third party tool? 😛

#

If it helps, use it

Especially as an indie developer.

#

Plus, Desmos is a website. You aren’t installing anything into unity

I'm having an issue with the way transform.TransformPoint() is working. If I pass it a vector that I have confirmed is (-.9, 0, -.9) then it should return a Vector3 that is in the world location of a point that is (-.9, 0, -.9) in the local transform space. However, that's not what I'm getting.

Here is my code:


        Debug.Log("Vertices[0] * .9f = " + Vertices[0] * .9f);
        Debug.Log(transform.TransformPoint(Vertices[0] * .9f);

If I take the outputs of those logs, create two empties, one at (-.9, 0, -.9) in local space, and the other at the point output by transform.TransformPoint((-.9, 0, -.9)) They are not in the same place. I have confirmed that transform is referring to the correct object. What am I missing here?

Rigidbody is one word. I would definitely find that odd

I normally use full words for almost everything. But.... i mean this is a rigidbody. It is like shortening camera to cam. You know what it is

thorny basalt
stoic oracle
# thorny basalt What is it outputting instead?

The results are close, but a few tenths of a unit apart. It seems dependent on the orientation of the parent of the transform object. I think I'll have to do some more testing. I just wanted to make sure I wasn't misunderstanding what it was SUPPOSED to be doing.

thorny basalt
#

Float math isn’t 100% precise.

You mean it's going to be off by like .3? That seems like absurd margin for error.

No, tenths. Yeah idk. I think I can figure it out tomorrow. But geez it had me stumped tonight.

I have a feeling it is some other force at play then the transformPoint method. Good luck though

the type you picked for prefab passing in instantiate is what matters

#

what is TABLE_ ?

#

u mean a prefix of "TABLE_"

#

interestn

#

ive never done anything like that but im sure its possible w/ someting other than a tryget

#

u could get all and loop thru checking the name w/ strings

#

u should use interfaces intsed

# 
   if(hit.collider.transform.TryGetComponent(out IInteractable interactable))
            {
                cachedInteractable = hit.collider.gameObject;
                if(Input.GetKeyDown(interactKey))
                {
                    interactable.Interact();
                }
            }```
#

yessir

#

soo things like my Pickup scripts are found w/ that interface

#

and everything interactable just has an Interact function we call

#

regardless if its a pickup, a switch, or w/e else

#

yes, thats what u can do w/ interfaces.. u havee 1 basic interactable interface or w/e

#

and u can inherit it from different classes (these can be different functionallity for different things)

#

or u could go the ez route and use a Tag

#

Table object or something.. and tag all ur things w/ Table..and u could check for that tag w/ the hit info

#

a switch statement would be a bit cleaner.. but yea interfaces sound like a better solution for what ur talkin about

#

thanks..

#

good luck.. come back if u run into any issues 👍

hey guys.
im trying to remove ALL triangles inside of a collision mesh, that have a normal similar to a normal vector returned by a raycast hit, in runtime.
is there a way for me to do that?

rocky canyon
#
  • raycast to get normal
  • access mesh data
  • calculate normals of each triangle in mesh
  • compare normals
  • remove triangles
  • update mesh
#

now as for the nitty gritty of that process, no clue

vast vessel
rocky canyon
#

after u remove triangles u have to recalculate / rebuild the mesh

#

you shouldn't be directly modifying the triangles either..

#

need to create a new list of triangles and then iterate thru that afterwards to rebuild it

#

but ive never done this.. soo this is just speculation

alr ill try, thanks 👍

I wrote code to load a VideoClip from Adressable and assign it to VideoPlayer.Clip, but the error output just says "Cannot read file". What is the cause? Sorry for this amateur question.

The question isn't amateur, how you asked the question is though

#

You need to provide information on what you're doing for others to be able to help

I wanted to use this code to overwrite the VideoPlayer source, but the editor error output just said "Cannot read file", so I don't know what is wrong.I would like to know what is causing this error.

How to get a bounding box that equals an orthographic camera space

#

or see if a bounding box is visible in screen space

languid spire

#

I'm trying to get a 2D bounding box kinda

#

I'm programming a renderer for my world, so I want to be able to know if a chunk is in the screen before rendering

wintry quarry
#

Use these two^

Help me!! I am spawning NPCs from a prefab, and I want them to follow a path of waypoints. If I put the script onto the prefab, then I can't assign it the waypoints which are GameObjects in my scene. If I put the script onto an empty GameObject in the scene (and call it NPCmanager) then I don't know how to dynamically assign it to the spawned NPCs. Any suggestions?

#

If you have a link to a tutorial or any advice, I'd love it!

languid spire
#

pseudo swan
#

Gotcha, so the behavior script (to follow waypoints) sits on the prefab. How do you assign the waypoints then?

languid spire
pseudo swan
#

They are game objects.

#

I can make them transforms or something.

languid spire
#

that is not what I asked

pseudo swan
#

It would be good if I could see them in the scene, but no mesh renderer so they are invis in the game.

#

What did you ask? Sorry, I'm a bit of a noob.

languid spire
pseudo swan
#

Do you want me to paste the script?

It's small. I can post it here, am opening the project right now. ChatGPT helped me make the script, but not exactly how you described. It doesn't sit on the NPC.

#

To clarify, I'm using a 3rd party asset called Ultimate Spawner 2.0 by Trivial Interactive to spawn the NPCs. The spawner has some extra features, such as events you can use. I've tried using an event called On Spawned (transform) to run a method that's supposed to assign the waypoints to the spawned NPC. The method is on an empty object called WaypointAssigner in my scene, to which I can add the waypoints since it's in the scene with them. But this is not working for me.

#

Let me post the scripts here:

# 
using UnityEngine.Events;

public class WaypointAssigner : MonoBehaviour
{
    public Transform[] waypoints; // Array of waypoint transforms

    public void AssignWaypointsToObject(Object spawnedObject)
    {
        GameObject myCube = spawnedObject as GameObject;
        if (myCube != null)
        {
            AssignWaypointsToCube(myCube);
        }
        else
        {
            Debug.LogError("Assigned object is not a GameObject");
        }
    }

    private void AssignWaypointsToCube(GameObject myCube)
    {
        AdventurerRoutine adventurerRoutine = myCube.GetComponent<AdventurerRoutine>();
        if (adventurerRoutine != null)
        {
            adventurerRoutine.waypoints = waypoints;
        }
    }
}
#

I didn't format that right, sorry.

#

Currently I'm just using a cube to represent the NPCs, calling it myCube.

languid spire
#

that looks fine, show the code for AdventurerRoutine

pseudo swan
# 
using UnityEngine;

public class AdventurerRoutine : MonoBehaviour
{
    public Transform[] waypoints; // Array of waypoint transforms
    public float speed = 1.0f; // Speed of movement

    private int currentWaypointIndex = 0;

    void Start()
    {
        // Check if there are any waypoints to go to
        if (waypoints.Length > 0)
        {
            StartCoroutine(MoveToWaypoints());
        }
    }

    System.Collections.IEnumerator MoveToWaypoints()
    {
        while (currentWaypointIndex < waypoints.Length)
        {
            Vector3 targetPosition = waypoints[currentWaypointIndex].position;
            while (Vector3.Distance(transform.position, targetPosition) > 0.1f)
            {
                transform.position = Vector3.MoveTowards(transform.position, targetPosition, speed * Time.deltaTime);
                yield return null;
            }

            currentWaypointIndex++;
        }

        gameObject.SetActive(false); // Disable the GameObject when all waypoints are reached
    }
}
#

This is a screnshot of my Infinite Spawn Controller, and you see the On Item Spawned (Transform) event.

#

I cannot assign a game object dynamically there, I don't know how.

languid spire
#

Dont see anything horibly wrong with that as long as your spawnObject (myCube) has the AdventurerRoutine script attached to it

pseudo swan
#

myCube has the Adventurer Routine script.

#

I think the problem is in the Infinite Spawn Controller, you see there is None (Game Object) there.

languid spire
#

you have not assigned myCube here

image.png
pseudo swan
#

But how? The cube is just a prefab until it spawns.

#

It doesn't exist in my scene.

#

Do I drag the prefab there from the Project window?

languid spire
#

looks like you are using the asset incorrectly becaue there is no spawning going on there

pseudo swan
#

I see. By the way, I don't have to use the spawner asset if it's simpler a different way.

#

And the cube does spawn in my scene, it just doesn't do anything.

languid spire
#

this should be
GameObject myCube = Instantiate(spawnedObject) as GameObject;
then no asset required

pseudo swan
#

It just sits there.

#

Where should that line be?

languid spire
#

then you can put the prefab in the event

languid spire
pseudo swan
#

Which script, WaypointAssigner?

#

Sorry, I'm being stupid.

languid spire
#

read your own code
GameObject myCube = spawnedObject as GameObject;

pseudo swan
#

I see it, it's in WaypointAssigner.

# 
using UnityEngine;
using UnityEngine.Events;

public class WaypointAssigner : MonoBehaviour
{
    public Transform[] waypoints; // Array of waypoint transforms

    public void AssignWaypointsToObject(Object spawnedObject)
    {
        GameObject myCube = Instantiate(spawnedObject) as GameObject;
        if (myCube != null)
        {
            AssignWaypointsToCube(myCube);
        }
        else
        {
            Debug.LogError("Assigned object is not a GameObject");
        }
    }

    private void AssignWaypointsToCube(GameObject myCube)
    {
        AdventurerRoutine adventurerRoutine = myCube.GetComponent<AdventurerRoutine>();
        if (adventurerRoutine != null)
        {
            adventurerRoutine.waypoints = waypoints;
        }
    }
}
#

Like this, right? And no other changes needed?

languid spire
#

only assign the prefab in the inspector

#

and, of course, actually add some waypoints to the list

pseudo swan
#

Well, no errors, but the cube still just sits there. I have the waypoints assigned to WaypointAssigner:

#

Ohhh

#

It moves! It moves!!!

#

OMG I almost had an anneurism.

#

Thank you so much, Steve!

#

May I bother you with another question?

languid spire
#

Sure, bear in mind this whole thing is much more complicated by you using an asset to do basic stuff

pseudo swan
#

In my game, the NPCs don't have physics. They don't have navigation etc. They just move from one point to another, in a linear fashion. (Or at least they should.) When the cube in this case follows the waypoints, it seems to interpolate or make a curve.

#

Is it possibe to tell it to go in a linear way, straight to the waypoint?

#

I can capture a video if that helps.

#

(Yes, I should do this basic stuff myself, but I thought the asset would make it simpler as I'm a noob. I should just learn to code better.)

languid spire
#

this code
transform.position = Vector3.MoveTowards(transform.position, targetPosition, speed * Time.deltaTime);
says move from A to B
so I dont see where a curve is coming from although you might want to look at Vector3.Lerp

pseudo swan
#

Sorry about the messy scene, just showing you the cube going through the floor.

#

But don't worry about it, I will figure this one out on my own/

#

Thank you for your help, you have no idea how helpful that was for me.

formal sable
#

There is a problem, I press the space bar and the panel is removed, I do not understand what it is... I didn't put anything anywhere. Can you help me please?

languid spire
#

that looks fine. you should look at the scene view with your waypoints selected

pseudo swan
#

Haha, the pivot of the cube is in the center of it, that's why it's going into the floor. Simple problem, sorry to have bothered you. Again, thanks for all the help!!

#

I will learn how to code better.

Why every guide want to find object by tag instead of by name?

wintry quarry
#

but, neither of those are recommended in general

twilit iris
#

By faster is the processing?

wintry quarry
#

there is no other meaning of faster

twilit iris
wintry quarry
#

otherwise some mix of opportunistic assignment and the singleton pattern or other dependency injection.

hey, I'm trying to change images of my imagecontainer (a panel that holds 5 images) by clicking on buttons. But the only way that it works is after I've clicked 5x on the next or the previous button, all images get loaded at once ._. can somebody help me '^'

What is Direct references? like resources.load?

wintry quarry
#

you wrote = when you should have written ==

wintry quarry
#

direct reference is assignment in the inspector

languid spire
fickle stump
#

AND THAT TOOK ME 45 MINS TO FIND

fickle plume
#

@fickle stump Don't spam off-topic images

twilit iris
#

is direct reference making public attribute and drag and drop asset?

fickle stump
#

sorry didnt know that thats spaming nowayMonkaS

languid spire
twilit iris
#

Ahhh...

fickle stump
#

@wintry quarry I've tried your fix, but somehow the the index only changes after beeing clicked 5 times..

image.png
#

it gets triggered at once after 5 clicks

wintry quarry
#

you're only calling SetImage in that if statement

#

why

#

shouldn't you be calling it no matter what?

#

some simple debugging will get you these answers in the future

fickle stump
#

i see.. thanks

#

coding is very hard for me unfortunately

languid spire
twilit iris
#

How do you change attribute inside prefab? Do you just make a new class with constructor to change certain attribute?

#

I want to generate text with certain font but different text everytime

(idk if this counts as really beginner coding so sorry if this is the wrong channel)
Does anyone know why my AddExplosionForce() is applying way too much vertical force and not enough horizontal force?

#

(also hi everyone)

wintry quarry
quiet pilot
#

The problem is I don't think it is

#

oh that's kinda cool it blocks "uh"

wintry quarry
#

Sounds like you should start debugging

quiet pilot
#

yeah

#

I keep forgetting not to say uh 😭

#

The point that the explosion is from should be right in front of the player

languid spire
wintry quarry
quiet pilot
#

and the upwards modifier is very low

quiet pilot
wintry quarry
quiet pilot
#

I can try to give context

#

lemme try this first

#

Although I do apply the explosion force through an external method

#

like the method is in a script on a different object

#

By the way, the explosion force sends the player extremely high up even if it's in the negatives (down to -1)

wintry quarry
quiet pilot
#

Yeah

twilit iris
wintry quarry
#

and just set up anchors/etc in the prefab

#

Instantiate(prefab, container)

twilit iris
#

I successfully make it as a child of a canvas

#

but somehow the position still wrong .-.

wintry quarry
#

again, proper anchoring etc

#

you are giving vague answers here so it's not clear what the "correct" position would be

quiet pilot
#

like this

image.png
twilit iris
#

Uhh how do I set the anchor by script again?

quiet pilot
#

oh sorry

#

I don't know that

twilit iris

        for (int i = 0; i < HighScoreList.Count; i++)
        {
            var temp = Instantiate(Font, new Vector3(50, 160 - i * 100, 0), transform.rotation, GameObject.Find("CanvasHighScore").transform);
            temp.GetComponent<TextMeshProUGUI>().text = "Score : "+HighScoreList[i].ToString();
            temp.GetComponent<TextMeshProUGUI>().anchor
        }```
