I'm a little fuzzy on the nitty-gritty details of delegate types et al.

#

some languages (C# included, in unsafe contexts!) let you know exactly where a thing is in memory

#

that location is stored in a "pointer" (it points to something!)

muted sonnet Apr 13, 2023, 1:26 PM

no point in getting into that rn tbh

can I not put a MonoBehaviour on an obj, if the MonoBehaviour is inside a Package ?

muted sonnet Apr 13, 2023, 1:26 PM

#

the main idea is, in C# functions can be put into variables

heady iris Apr 13, 2023, 1:27 PM

#

it's very convenient for allowing flexible behavior

#

you can pass a function that compares things into a sort function

#

and bam, you can sort a list however you'd like

If i set my raycast on one object and decide which object the pointer should interact with, its not going to stop interacting with the other objects because i have canvasses on Top of each other

magic harness thats gona create spaghetti code whenever i have to add more content

not if you keep it reasonably organized

#

actually, I guess I'd do it like this:

#

have a single input controller component

#

it is the only thing that listens to mouse input

#

it has a list of places to try that input in

#

it tries them in sequence until one of them says it did something

magic harness Apr 13, 2023, 1:29 PM

The thing is that these other canvas have buttons that listen for the input independently

I got a screen space object that is on top of my world space object

The screen object has buttons that i use to select what thing is going to move in my world space object, and the click on my world space object decides where its going to move

You can even do this, and store a reference to the instance in a field if it does not exist yet.

private EnemyManager _enemyManager = null;
private EnemyManager EnemyManager {
  get {
    this._enemyManager ??= EnemyManager.Instance;
    return this._enemyManager;
  }};

void Update()
{
  this.EnemyManager.CanAttackPlayer();
}

#

Not that it matters here

scenic hinge Apr 13, 2023, 1:37 PM

#

magic harness sure, but the problem is in multiple canvas

Then as long as sorting order for the overlay is 0, it’ll always render before the other, also in the hierarchy make sure the canvas you want on top is higher up on the hierarchy

Top one is a property, bottom one is a field that you're assigning to

#

A property does not hold a value, it gets it from something else

#

If you define a property without an explicit getter, it's retrieved from something called a backing field

#

You're defining it to fetch it from EnemyManager.Instance

#

So the thing with properties is that you're not setting it in Awake, which prevents race conditions, which in turn is bad

scenic hinge Apr 13, 2023, 1:46 PM

magic harness none ever disappears

scenic hinge Apr 13, 2023, 1:50 PM

I think that is fairly easy, you just create a bool that gets set to true when you click on the screen space GUI, then you query for that every time on the world space GUI, or you check which UI your pointer selects first and ignore interactions thereafter

magic harness Apr 13, 2023, 1:51 PM

the bool doesnt work because if i set it to true after i click the screen space object then the functionality will run on world space anyway

So if you are looking for just generic input, you can use the input package, however I’d recommend looking for SAMYAMS inputsystem guide

cobalt elm Apr 13, 2023, 2:29 PM

scenic hinge So if you are looking for just generic input, you can use the input package, how...

No, I have the actual input down. Unity just does some backend stuff to connect the input to the eventsystem for UI. I want to manually connect an input device to the eventSystem.

#

in the docs ive found, there is a base input module but that turns into a legacy input module in 2020.3 (the version im using). Thus leaving me with no where to find how to event system finds the input device.

no, the opposite. whats important for gameplay is the settlements + connections between them (ie i just need to know that settlement X is connected to settlement Y, not the exact path that is used to connect them), i need those in gameobjects/components for the gameplay. the terrain is just eyecandy. and i can manually recreate that map, but im really looking for something that allows me to procedurally generate a large variety of maps

yeah. mapmagic2 does that part pretty well, i can have it scatter the settlements then pathfind and it generates a bunch of nice splines that connect the settlements in a satisfactory way... but then there doesnt seem to be anything in mm2 that actually outputs the splines, it just seems to be built to use them to draw textures on the terrain object, and i havent found a way of using the mm2 output to determine settlementX connects to settlementY

so that green scatter node is what scatters my provinces (which can be seen as little clusters of houses), and then it flows into that orange interlink node which generates a bunch of splines to connect those provinces, and then the latest thing ive been trying is the orange scatter node, which takes a list of splines and creates a list of locations which i then dump "PathPoints" on to (the orange dots you see in the scene)

#

but theres no way within mm2 that i have found to attach any other data to them. trying to think of a way to use them to generate logical X->Y connection information after the mm2 generation is done

#

and then got to that point and thought "dammit is there another asset that could do this easily" 🙂

#

30 years of software engineering and im lazy af, i dont want to write code, i want to ship games XD

#

i can increase the # of objects placed in the scatter node

but theres no way within mm2 that i have found to attach any other data to them. trying to think of a way to use them to generate logical X->Y connection information after the mm2 generation is done
I wouldn't try to do all that stuff inside MM itself

I would just use MM to generate the terrain and the provinces themselves (with Objects in MM as you have done there). I would then basically just take over with my own custom graph generation logic. Pretty much just check within a radius of each province to consider as "neighbor" provinces and then it's just standard graph logic from there

#

other than drawing the splines of course...

quick kindle Apr 13, 2023, 4:01 PM

#

leaden ice other than drawing the splines of course...

yeah i thought about that... but then i dont get the visual representation of the roads between the provinces, and that feels meh from a ux perspective

leaden ice Apr 13, 2023, 4:01 PM

#

You get it... just not from MM

#

Use the Unity splines package or similar and draw the edges of the graph

quick kindle Apr 13, 2023, 4:01 PM

#

hm

#

looking into unity splines, never used em before

#

can they be used to write onto the terrain?

leaden ice Apr 13, 2023, 4:02 PM

#

As a crude first pass you can just draw them as straight lines with simple LineRenderers

leaden ice Apr 13, 2023, 4:02 PM

#

quick kindle can they be used to write onto the terrain?

I mean they're pretty much general purpose mathematical splines

#

theoretically you can do whatever you wish

#

there's no built in terrain drawing feature though

#

Is there a reason they need to actually be baked into the terrain?

#

rather than for example separate meshes laying on top

quick kindle Apr 13, 2023, 4:03 PM

#

ah not neccessarily baked into terrain, but i would like a visual effect

#

mm2 just has all these super nice nodes for splines, like you can have it keep the splines to minimal elevations, so it naturally wraps around steep mountains and such

#

and a stamp node that flattens the ground around the spline so it looks natural

#

its just frustrating bc it seems like mm2 gets me 99% of the way there, and if i handroll my own pathfinding and generation, i'm having to write a bunch of stuff that mm2 does for me, just to get that last 1%

heady iris Apr 13, 2023, 4:06 PM

it would be very convenient to re-use the same paths, for sure

leaden ice Apr 13, 2023, 4:06 PM

you probably have something else going on, this method is not expensive

heady iris Apr 13, 2023, 5:56 PM

then find the nearest edges of the two surfaces and do a raycast between them

or maybe overlap a box in that area

if it's clear, make a link

This set up is on my laptop which is only different from my desktop PC in that the laptop has Visual Studio 2022 professional, and my desktop PC has the 2022 Community edition of VS

#

I've tried all the common fixes like reinstalling, running a 'repair' of visual studio, etc. still have the same problem

dapper hinge Apr 13, 2023, 6:57 PM

Anyone know what I'm doing wrong?
I just have this

public class Keyboard : MonoBehaviour
{
    private TouchScreenKeyboard keyboard;
    public void OpenKeyboard() 
    {
       keyboard = TouchScreenKeyboard.Open("", TouchScreenKeyboardType.NumberPad);
    }
}

The OpenKeyboard() method get's called in the OnSelect event of an inputfield like in the image

#

No keyboard opens up though, I'm using Unity Remote 5 to test it

potent sleet Apr 13, 2023, 6:57 PM

did you read the docs?

dapper hinge Apr 13, 2023, 6:58 PM

Not sure what all of these GUI.button() if statememts are about

how do I check if a rect transform has the mouse position?

#

I tried RectTransformUtility.RectangleContainsScreenPoint(rectTransform, Input.mousePosition)

#

also tried RectTransformUtility.ScreenPointToLocalPointInRectangle(rectTransform, Input.mousePosition, null, out _)

#

tried using Camera.Main

#

tried doing rectTransform.InverseTransformPoint (gives some huge numbers)

#

nvm got it

dapper hinge Apr 13, 2023, 7:09 PM

#

Camera.main.ScreenToWorldPoint(Input.mousePosition); Get's you the coords of the mouse
rectTransform.TransformPoint(rectTransform.rect.center);Get's you the transforms coords too I think

#

oh

#

:/

heady iris Apr 13, 2023, 7:10 PM

#

TransformPoint goes from local space to world space

#

InverseTransformPoint goes from world space to local space

@potent sleet I need some more help here if you can. Or anyone really.

I don't really know why this decal is appearing before the draw distance. I have this, which adds the distance (from the center of the bound (drawn in blue) to the edge of itself) to the render distance. I then check the distance from the camera's near clip plane (just camera's forward multiplied by the near clip plane distance in world space) to the center of the bound. Yet it's still slightly off, I don't know why.

Vector3 zPlanePos = Camera.main.transform.TransformPoint(Camera.main.transform.forward * Camera.main.nearClipPlane);

_bounds.IntersectRay(new Ray(_bounds.center, (zPlanePos - _bounds.center).normalized), out float distance);
float realDistance = (-1 * distance) + projector.drawDistance;

Debug.Log(realDistance);
Debug.Log(Vector3.Distance(zPlanePos, _bounds.center));

Yet the decal appears before the second debug log statement is equal to the realDistance.

#

(in the image I'm logging Vector3.Distance(zPlanePos, _bounds.center) > realDistance). It's true, yet the decal is shown. Also I am using the near clip plane of the camera instead of the player position because I could not figure out why the decal was appearing before the player got close. Using the near clip plane position makes it almost correct. almost.

heady iris Apr 13, 2023, 7:27 PM

#

does the behavior change if you change the near clip plane?

#

if not, then that's probably not relevant

shell scarab Apr 13, 2023, 7:28 PM

#

heady iris does the behavior change if you change the near clip plane?

no it doesnt. I forgot I could even change it to test, I barely touch the camera haha.

#

still can't figure out why it renders before the distance of the box from the center of the box + the render distance

heady iris Apr 13, 2023, 7:29 PM

#

also, I'm thinking of restructuring my entire game, again, and I could use a sanity check

Right now, each stat in my game -- health, stamina, mana, whatever -- is identified by an enum. This has already led to headaches, as seen in exhibit A:

#

I had the idea to make a ScriptableObject type that represents a stat. The type would hold localized strings for the name/description of the stat, plus the stat icon.

#

one issue I see that is that I'll need to do something like Resources.LoadAll to get a list of every stat

#

instead of just iterating over the values of the Stat enum

#

(i'll also be adding more kinds of stats, some of which are conceptually different from others. it'll be about as elaborate as Elden Ring/Nioh/etc.'s list of stats)

#

so those will probably need different types

#

I guess I should just give it a whirl and see how it feels. I'm still very early in development.

well how are you using the enum?

heady iris Apr 13, 2023, 7:32 PM

#

shell scarab well how are you using the enum?

Here's an example.

#

swinging the sword costs 10 stamina, and deals 20 vitality + 10 stamina damage

#

so, in this case, I'd just be replacing the enum dropdown with a field that holds a Stat reference

#

One place that this seems like a win is localization: I'm doing some...suspicious stuff right now

#

    private string StatKey
    {
        get
        {
            return System.Enum.GetName(typeof(Stat), stat);
        }
    }

#

this gets turned into a LocalizedString

#

actually, basically everything I do with enums feels suspicious

#

enums are funky little guys

shell scarab Apr 13, 2023, 7:35 PM

#

tbh I like enums bc you can use it as a flag enum and use bitwise operators so you can easily say "this stat or this stat or this stat or this stat or this stat" in an if statement. I would even set up a method that I could use to take points away from multiple stats based on an int that represents the flag enum.

heady iris Apr 13, 2023, 7:35 PM

#

yeah, although I don't have it set up properly for that

#

since the enum values are just sequential

#

I am using enum flags like that in another place, where different interface elements are enabled depending on the current game state

#

I think the big hang-up is iterating over all of the stats

#

I guess I'd just make a static class that does a big Resources.LoadAll once

shell scarab Apr 13, 2023, 7:36 PM

#

why do you need to iterate over all the stats with the current system?

heady iris Apr 13, 2023, 7:36 PM

#

shell scarab why do you need to iterate over all the stats with the current system?

any situation where I want to do something with every stat, like drawing them all to a status screen

heady iris Apr 13, 2023, 7:37 PM

#

heady iris I guess I'd just make a static class that does a big `Resources.LoadAll` once

and then it'd just have a nice static list of the stat SOs

#

it'd even sort them correctly so they show up in the order I want

#

rather than just "whatever order they have in the enum"

shell scarab Apr 13, 2023, 7:37 PM

#

heady iris any situation where I want to do something with every stat, like drawing them al...

which is where the bitwise operators could come in. (make a method that separates out each field from an int value and performs a supplied action on the stat? Then you'd just need to call that method whenever you want to do something for certain stats, and pass a lambda expression to be ran on each stat.)

#

Well, are you concerned with performance or ease of use? bc you said you're in early development, so it's not a good idea to be concerned with performance right now, or so I've heard.

heady iris Apr 13, 2023, 7:39 PM

#

Ease of use generally wins.

#

Critically, it shouldn't feel gross to add and remove stats later

...which, lol

I am thinking about the potential cost, though

the big thing will be that I will look up stats with a SO reference, rather than an enum value

Hi, I'm facing a problem with my game, everything was going smoothly and all of a sudden i can't see the map, even by restarting the game

shell scarab Apr 13, 2023, 7:41 PM

#

heady iris I am thinking about the potential cost, though

I mean a for loop looping through even 100 stats wouldn't be too big of a performance impact in the big picture if you aren't doing computationally heavy actions each time.

hey, deleting the Stat enum only made 9 errors

#

that's concerning

#

🤨

shell scarab Apr 13, 2023, 7:42 PM

#

maybe you should make a static class and have that handle everything, so if you decide to switch back to enums later you only need to change it in one place rather than a bunch of places @heady iris

heady iris Apr 13, 2023, 7:42 PM

#

Yeah, I'm definitely gonna have a static class that holds all of these SOs

#

thanks!

shell scarab Apr 13, 2023, 7:43 PM

#

yup! And that way if you want enums it shouldn't be.. too hard.. hopefully.. to switch back.

heady iris Apr 13, 2023, 7:46 PM

shell scarab still can't figure out why it renders *before* the distance of the box from the ...

what if you change the size of the box?

#

I'd fiddle with more variables

#

I wonder if it's accounting for how the box could be rotated

#

so that a corner is facing you

#

you'd need to add...a factor of sqrt(3)?

shell scarab Apr 13, 2023, 7:47 PM

#

the render distance is definitely from the edge of the box to the camera. So if you stood in a spot and rotated the decal so a corner was within range, it would start rendering.

heady iris Apr 13, 2023, 7:47 PM

#

ah, okay

shell scarab Apr 13, 2023, 7:47 PM

isStopped us causing error
can only be called on an active agent that has been placed on a NavMesh.

heady iris Apr 13, 2023, 8:01 PM

#

heady iris I think I'll give it a go

ah, one nuisance: this is going to work great for stuff like weapon scaling, since the weapon can have a list of stats that are used to determine its damage

...but it's inconvenient for things like health. An entity checks every update if it's at 0 health, and, if so, dies. But now it doesn't really know what "health" is.

#

It just has a bunch of stats.

#

stuff like "health" and "stamina" feel very different from things like "strength" and "reflexes"

#

they're numbers that go up and down all the time and have very concrete meanings

#

I guess I can just tell the entity what stat should be used for deciding if it's dead, etc.

#

that could certainly lead to interesting things like an enemy that only dies when it runs out of mana

Having an issue with Unity sort order--it seems that the sort order doesn't take effect unless I modify it after hitting play

#

I have a canvas at sort order 0, then a background sprite at 1, and text at 2. But at runtime the background sprite renders over the text. If I change the text sort order to 3 at runtime (or background to 0) then it works. But it has the same issue every time I rerun it

What is the best way to surround enemys around player

I have found one tutorial about that which has this script

    private void MakeAgentsCircleTarget()
    {
        for (int i = 0; i < Units.Count; i++)
        {
            Units[i].MoveTo(new Vector3(
                Target.position.x + RadiusAroundTarget * Mathf.Cos(2 * Mathf.PI * i / Units.Count),
                Target.position.y,
                Target.position.z + RadiusAroundTarget * Mathf.Sin(2 * Mathf.PI * i / Units.Count)
                ));
        }
    }

But problem in this if target is not accesable (out of navmesh area) enemys will go nuts.

or i can create waypoints around player and every enemy will check the closest and then move to that but this time there will be a lot of distance check which will bad for performance

can you suggest me bast way to achieve that

Hi! I have a need to send some web requests to initialise objects. I want to do it in a coroutine, but I need them to be executed in the order they are added, otherwise everything will break. Currently I have this:
There is ICoroutineTask interface with methods Start, Wait and Finish.
There is WebRequests class that generates ICoroutineTasks from a UnityWebRequest, with Start Wait and Finish with Wait being request.SendWebRequest().
The setting of local variables is done in Finish method
And finally the code for resolving the enqueued tasks is:

        private IEnumerator WorkCoroutine()
        {
            while(_running)
            {
                if(_tasks.Count == 0)
                {
                    yield return new WaitForSeconds(0.1f);
                    continue;
                }
                var task = _tasks.Dequeue();
                Debug.Log("Dequeued task");
                task.Start();
                yield return task.DoWork();
                task.Finish();
                Debug.Log("Finished task");
            }
        }

But what I do does not work..

            yield return null;
            bgMesh.material.color = Color.Lerp(start, "246F2A".Color(), delta / duration);
        }
        Module.HandlePass();
        
    }

tulip quartz Hey, Im very confused as to why putting the `yield return null` specifcaly there...

It makes it wait until the next frame. It's the shortest amount of time you can wait, because coroutines are updated at the same rate as Update.

When jumping (with current system) despite having no "air control" the players rotation is still able to change the direction of the in air velocity. I want to make it so that when in the air you are still able to look around but do so wont change your momentum.

the private field was not accessed anywhere, only the getter and setter

like subscribing to a static event every single time the game runs, piling up more and more

#

for a sanity check, do you find any extra references if you shift+F12 the private field?

cerulean oak Apr 13, 2023, 9:42 PM

#

ctrl + F?

heady iris Apr 13, 2023, 9:42 PM

#

no, shift+F12 to find all references

#

(i think that's the shortcut in VS)

#

it finds every place in your code that references something

#

the opposite of F12, which takes you to where something is defined

In the editor, there's this nice system for moving an object based on its center, which takes its childrens' position and scales into account. Is there any built-in way to do this through code, or should I make my own function for it?

#

cold parrot Apr 13, 2023, 9:54 PM

#

inner yarrow In the editor, there's this nice system for moving an object based on its center...

you can just GetComponentsInChildren<Transform>() and average their positions, then calculate the move delta and add that to the parent's transform position

cerulean oak Apr 13, 2023, 9:55 PM

inner yarrow In the editor, there's this nice system for moving an object based on its center...

cerulean oak you mean moving localPosition?

In this case I want the local position because I'm using a script that creates a bunch of 3d text objects, but they are centered at the bottom left, so I want to set their local position to make them centered around the parent object.

somber ether Apr 13, 2023, 10:08 PM

cerulean oak idk if im having an ictus or that made no sense

If you are responding to me, it does make sense. Its just generating a new playerprefs when a product is purchased

cerulean oak Apr 13, 2023, 10:08 PM

#

I mean the sentence

#

I dont get what you mean

somber ether Apr 13, 2023, 10:09 PM

#

If you have a shop in a game for buying avatars and someone buys something, you dont want them to buy it again

#

So I want to only instantiate playerprefs that they own (for the tab where they can equip their purchased ones)

cerulean oak Apr 13, 2023, 10:11 PM

#

you can use
PlayerPrefs.SetInt("item" + itemIndex , 1);
to store the purchased items
and
```PlayerPrefs.GetInt("item" + itemIndex) == 1````
to get if an item has been purchased or not

somber ether Apr 13, 2023, 10:12 PM

#

No, because when theres 50 items in the shop we dont want to check each individual pref

cerulean oak Apr 13, 2023, 10:12 PM

#

so dont use playerprefs

somber ether Apr 13, 2023, 10:13 PM

#

regardless of save method youll need a loop

cerulean oak Apr 13, 2023, 10:13 PM

#

you could also use the int as a flag, and store 32 bools per int

#

but like

#

just

#

dont use playerprefs

somber ether Apr 13, 2023, 10:13 PM

#

why not

cerulean oak Apr 13, 2023, 10:13 PM

#

idk

#

you are the one who doesnt want to call one GetInt for each item

#

why not?

somber ether Apr 13, 2023, 10:14 PM

#

because thats weak code, using else if that many times

cerulean oak Apr 13, 2023, 10:14 PM

#

what?

somber ether Apr 13, 2023, 10:14 PM

#

youd rather just use a foreach loop to check the array for all the items you do own and instantiate those into the shop

cerulean oak Apr 13, 2023, 10:14 PM

#

just use a loop

somber ether Apr 13, 2023, 10:15 PM

#

I know to use a loop, thats not the question I asked. I am asking someone who is smart enough to give a detailed code

#

#

Thats what I have so far

#

Which is likely wrong

cerulean oak Apr 13, 2023, 10:15 PM

that wont work

you need to use a normal for loop

somber ether Apr 13, 2023, 11:34 PM

#

potent sleet why not Dictionary

Code example?

#

I have one tab where ppl equip owned items, and one tab where ppl buy new items

#

so on start I generate the playerprefs to the size of the array. Now for next loading when it will instantiate all the products that are 0(not bought yet)

potent sleet Apr 13, 2023, 11:39 PM

it has length

cause its fixed

somber ether Apr 13, 2023, 11:41 PM

So it should instantiate all the purchased prefabs only

such as producttype9

solemn raven Apr 14, 2023, 12:09 AM

hi,
i have a drag and drop situation , where i want to get the item the mouse pointer is hovering on once drag ends to make a drop

    public void OnEndDrag(PointerEventData data)
    {
        GameObject go = data.pointerDrag;
        if(go)Debug.Log($"go:{go}");
    }

the value of go is always the original parent before drag , not sure why

latent latch Apr 14, 2023, 12:15 AM

#

Best to debug with all the other drag events at once

#

and onpointerclick

solemn raven Apr 14, 2023, 12:17 AM

#

i also did that

public void OnDrag(PointerEventData data)
    {
        Debug.Log($"Draging :{data.pointerDrag}");
    }

also the original parent even though iam hovering over many other objects

#

is there is a way to just get the object underneath the pointer at anytime regardless of the drag event ? cause it seems to be buggy

latent latch Apr 14, 2023, 12:21 AM

#

Could be like a raycast problem perhaps? Is there something blocking what you're trying to drag? For detecting what's underneath the pointer when dragging, I would assume you could just cast a ray yourself assuming you've not repositioning what you're dragging (and is under the pointer blocking the ray)

solemn raven Apr 14, 2023, 12:23 AM

#

thanks , i will try that 🙂

potent sleet Apr 14, 2023, 12:24 AM

#

somber ether

I would still use a dictionary

latent latch Apr 14, 2023, 12:24 AM

#

I havent really used it for a while, I just remember a lot of the drag events being fluff. You only needed like the OnEndDrag for it all to work. (still, the other events are needed to display you 'moving' the ui element for the user)

somber ether Apr 14, 2023, 12:25 AM

#

My debug log says its going to spawn 3 different types of prefabs, but it only spawns prefab #2 three times, whys that?

potent sleet Apr 14, 2023, 12:26 AM

#

I would not use rely on playerprefs for this..

somber ether Apr 14, 2023, 12:27 AM

#

potent sleet I would not use rely on playerprefs for this..

its already working tho. The instantiate code just seems wrong

potent sleet Apr 14, 2023, 12:27 AM

#

just cause it's working doesn't mean it's not flimsy code but I guess

somber ether Apr 14, 2023, 12:28 AM

#

Im not staying with playerprefs, its just the fastest way for now so I dont need to write obsessive classes for file saves

potent sleet Apr 14, 2023, 12:29 AM

#

somber ether its already working tho. The instantiate code just seems wrong

well debug your PlayerPrefs.GetInt then

#

so you know the value ur actually getting

#

not everything needs to be 1 liners

#

var productIndex = PlayerPrefs.GetInt("producttype" + i); Debug.Log(productIndex )

somber ether Apr 14, 2023, 12:32 AM

#

Ah I see what went wrong. im getting the value of the prefs

#

The value is always going to come out as 1

potent sleet Apr 14, 2023, 12:33 AM

#

is product type supposed to be a bool

somber ether Apr 14, 2023, 12:33 AM

#

When you buy something from the shop it takes the product ID and sets its int to 1 as you now own it.

#

Now I need to instantiate all of those that exist/purchased

#

So the player can equip it

#

I can solve it tho

#

Instead of setting each product to 1, set the product to the product id

potent sleet Apr 14, 2023, 12:36 AM

#

what's wrong with

public class Product
{
    public int Id;
    public string Name;
    public string Description;
    public GameObject ProductGO;
    public Product(int id, string name, string description, GameObject go)
    {
        this.Id = id;
        this.Name = name;
        this.Description = description;
        this.ProductGO = go;
    }
}```

then you on purchase store them in your player inv..

#

List<Product> for example or Dict

somber ether Apr 14, 2023, 12:39 AM

What do you mean "to slow down time only inside a capsule collider"?

I think I understand what you want to achieve, but it requires handling your own physics setup. You'd need to handle all of your object velocity to be able to control "time" when inside a trigger volume.

The problem is that you're using a Unity game engine where physics is already built for you. What you're trying to accomplish goes beyond than using Unity's default physics. You would need to handle your own physics solver to achieve "slow" and "timed" movement.

My object has an instance each of Script A and Script B.
During Awake(), Script A references a UnityEvent in Script B, and adds a listener to it to run a function in Script A.

Awake() in script A runs properly, and so does the UnityEvent in Script B, but the listener is not running. I think it's not being added in the first place (possibly due to the event somehow being triggered before Awake() runs), but I don't know hot to check this.

All of UnityEvent's built-in functions only work for its persistent listeners, so I can't use those.

Thoughts?

no can do, I'm under NDA. I got an idea from another guy to run it in Start() though

public void ContarCantNoticias()
    {
        dbReference.Child("noticias").GetValueAsync().ContinueWith(task =>
        {
            if (task.IsFaulted)
            {
                Debug.Log("TASK FALUTED xD");
            }
            if (task.IsCompleted)
            {
                dbReference.Child("noticias").RunTransaction(mutableData =>
                {
                    IDictionary<string, object> cantNoticias = (IDictionary<string, object>)mutableData.Value;
                    Debug.Log(cantNoticias.Count);
                    debug.text = cantNoticias.Count.ToString();
                    mutableData = null;
                    return TransactionResult.Success(mutableData);
                });
            }
        });
    }

When I add this 2 lines of code it works on the 2nd time I call the void (I dont want this to happend):

  Debug.Log(cantNoticias.ToString());
  Debug.Log(dbReference.Child("noticias"));

But if I remove them it just stops working (also dont want this to happend tho)

I'm getting this error:

RenderTexture.Create failed: colorFormat & depthStencilFormat cannot both be none.

when I call this:

but the render texture is set to this:

RenderTexture rt = new(Screen.width, Screen.height, UnityEngine.Experimental.Rendering.GraphicsFormat.R32G32B32A32_SFloat, UnityEngine.Experimental.Rendering.GraphicsFormat.None);

or this (tried both):

rt = new(Screen.width, Screen.height, 0, RenderTextureFormat.ARGB32, RenderTextureReadWrite.sRGB);

But neither of those have both colorFormat & depthStencilFormat set to none, so I'm very confused. Any help with this?

would the render texture somehow be getting reset?

I have it stored in the class and never changed so I wouldn't think so.

quartz folio Apr 14, 2023, 6:03 AM

#

Slightly scary where you're rendering the main camera from, but I won't question that part too much

#

You'll probably have to show where you initialise the RT

#

You should be calling Create yourself if you haven't already

#

(and Release for that matter)

shell scarab Apr 14, 2023, 6:04 AM

#

yes it is scary. I couldn't figure out a way to get the pixel color from the screen in a different way.

#

would I really need to call Release if I just reuse the same render texture over and over?

quartz folio Apr 14, 2023, 6:05 AM

#

You use it when you're done

sweet basin Apr 14, 2023, 6:36 AM

shell scarab what's supposed to happen and what is happening?

I only sent the part with the reloading because that's the issue. Can you tell me what exactly do you not understand so I can properly elaborate?

shell scarab Apr 14, 2023, 6:37 AM

#

you said that you're having an issue with the code but didn't say what the issue was, could you start by saying what the issue is?

#

I know you said you don't know what the issue is, obviously if you did you wouldn't be asking here, but what's happening with it right now?

sweet basin Apr 14, 2023, 6:38 AM

#

Ahh nvm I reread your question. In any case, nothing happens, the magazine I have stays at 0 once I empty it and the function never happens, and what is supposted to happen is, after the R key is pressed the reload starts, it lasts for "gunData.reloadTime" which I set to be 1,5 seconds and the current magazine should be equal to the overall mag size

shell scarab Apr 14, 2023, 6:43 AM

#

hmm well first I don't think you need the ?. operator to invoke an Action, could be wrong though.

second, have you put debug log statements in the if statement that gets the reload input to make sure that works?

third, have you tried putting debug log statements in the reload function? Could gunData.reloading be set to true already? maybe it's not getting through that. As for the activeSelf, I'm just going to assume that's true, although you don't need this to access gameObject.

Next, have you put debug log statements in the Reload coroutine? In the code you sent you have a typo, gunData.reloadTIme, I assume it's supposed to be gunData.reloadTime. Also, could that value be very large?

Finally, could gunData.magSize be 0?

#

@sweet basin that's everything I could see that could be wrong, besides the fact you should probably unsubscribe from those events in OnDestroy() or something.

sweet basin Apr 14, 2023, 6:50 AM

#

shell scarab hmm well first I don't think you need the ?. operator to invoke an Action, could...

I sincerely apologize to say this but I don't understand what you mean with the second and third point. I'm quite new to game development and I wasn't too deep into programming before this either so it's really hard to understand. As for the ?. operator, I'm confident it's not an issue because the action before reloading, the one that deals the actual damage to the target, works just fine with the same operator. And as for the fourth point, yes I made a slight mistake with the reloadTime typo, managed to correct it but the issue is the same still.

shell scarab Apr 14, 2023, 6:51 AM

using Debug.Log(object); at various points in the code to print to the console is what I mean, to verify it's reaching there.

shell scarab hmm well first I don't think you need the ?. operator to invoke an Action, could...

Ohh yeah I also tried changing the values, so that's not the issue also

sweet basin Apr 14, 2023, 6:54 AM

#

shell scarab Apr 14, 2023, 6:54 AM

#

ah ok, so it's not something easy we missed then, compiler would have complained.

#

yea, just try the Debug.Log statements. I would literally just do
Debug.Log(1);
Debug.Log(2);
Debug.Log(3);
....
and so on, and see where it doesn't reach.

sweet basin Apr 14, 2023, 6:55 AM

#

For every function?

shell scarab Apr 14, 2023, 6:56 AM

#

no

#

In the code that you sent (I don't know if these line numbers match up to your cs file) I'd put one after line 21, after line 47, after line 49, after line 55, and after line 57.

sweet basin Apr 14, 2023, 7:01 AM

#

Uhh non of them pretty much

#

#

I have emptied the mag and I got no info after trying to reload

#

I tried to see if I did the debug wrong by putting one message on the shooting command also, but that one worked just fine and I got the info

#

And so I deleted it

shell scarab Apr 14, 2023, 7:02 AM

#

so I suppose it's not detecting the reload key

#

you put a Debug.Log() statement inside of the if (Input.GetKeyDown(reloadKey)) if statement right?

sweet basin Apr 14, 2023, 7:06 AM

#

Yes

#

shell scarab Apr 14, 2023, 7:06 AM

you're serializing the field, are you sure it's set to R?

#

nonono, in the inspector

sweet basin Apr 14, 2023, 7:07 AM

#

I mean I did type the KeyCode.R after it

shell scarab Apr 14, 2023, 7:07 AM

#

when you Serialize the field it exposes it in the inspector, so it could be changed.

#

check the inspector of the object that has the PlayerShoot component

sweet basin Apr 14, 2023, 7:08 AM

#

Could be cuz of this that I don't have it

#

shell scarab Apr 14, 2023, 7:09 AM

#

sweet basin

Sorry, I'm a bit confused... by inspector I meant the thing on the right side of unity, as shown in the screenshot you sent here

#

just click on the object that the PlayerShoot component is attached to

sweet basin Apr 14, 2023, 7:10 AM

#

Yes, but it wasn't there, If I delete the [HideInInspector] I can see the bool element

#

shell scarab Apr 14, 2023, 7:11 AM

#

sweet basin

yes, but that's not what I'm talking about. I'm talking about this

#

it seems that reloadKey is assigned something else in the inspector.

sweet basin Apr 14, 2023, 7:12 AM

#

I'm so sorry to bother you like this and lack so much knowledge, but I really am not sure how to check that

#

I just went through every folder and script and I have nothing

#

With reload

#

Ohhhhhh nvm I realised what you were talking about, I forgot to add the PlayerShoot to my gun...

#

I was sure I added it since I added the Gun script also

#

I mean I was sure everything in the inspect was right, so I only focused on the code

#

I see it works now, thank you for all the help anyways, and I'm sorry to trouble you like this

shell scarab Apr 14, 2023, 7:18 AM

#

lmao

#

so unity uses components. When you create a script by default it can be attached to any game object. I was trying to ask you to select the gameObject that you had added that script to and check the inspector, the panel on the right side of the screen.

sweet basin Apr 14, 2023, 7:20 AM

#

Yes I know that, I understood later what exactly you meant, but I thought that I had already attached all the scripts

#

That's why I really didn't understand the problem

vague slate Apr 14, 2023, 9:22 AM

I am a bit confused

Hi guys! I have a question regarding coroutines. So assuming I have a code like this:

{
  if(x)
    {
      print("hi");
      x = false;
    }
   else
    {
      StartCoroutine(UpdateX());
    }
}

private IEnumerator UpdateX()
{
  yield return new WaitForSeconds(1f)
  x = true;
}```

#

will the coroutine keep on starting again at the beginning before it could pass the if condition in the Update() function?

knotty sun Apr 14, 2023, 10:43 AM

#

steady granite Any idea why this appears when I call DontDestroyOnLoad on referenced object but...

Depending on which Unity version you are using, you might want to update your TextMeshPro package

knotty sun Apr 14, 2023, 10:44 AM

#

fathom plaza will the coroutine keep on starting again at the beginning before it could pass ...

yes, for 1 second, which is a lot of Update cycles

#

put the x = true before the yield to stop this, but it will only half the problem

thin aurora Apr 14, 2023, 11:00 AM

#

fathom plaza will the coroutine keep on starting again at the beginning before it could pass ...

It wont keep starting at the beginning. It will constantly create a new Coroutine and the ones before that will also continue to run. Starting a coroutine twice does not mean the first one will be aborted

#

So in your case, it will be started as often as is possible in 1 scaled second

#

So assuming you run at a constant 60 fps, and your timescale is unchanged, 60 Coroutines will run at once

So this is probably not a good idea

knotty sun put the x = true before the yield to stop this, but it will only half the proble...

Thanks for this but the way that I intend to use the code is so that there's a delay. Would you have any suggestions on a better way of doing delays?

I plan on just putting another bool

fathom plaza I plan on just putting another bool

exactly

#

bool isRunning = false;
private void Update()
{
  if(x)
    {
      print("hi");
      x = false;
    }
   else if (!isRunning)
    {
      StartCoroutine(UpdateX());
       isRunning = true;
    }
}

private IEnumerator UpdateX()
{
  yield return new WaitForSeconds(1f)
  x = true;
   isRunning = false;
}

yea exactly what im doing now lol

knotty sun Apr 14, 2023, 11:07 AM

perfect

#

been stuck on a bug regarding input for about an hour

#

and I had to act like a controller for an hour to understand it

#

thanks for the help though!

knotty sun Apr 14, 2023, 11:11 AM

#

@fathom plaza tbh you could just do

private void Update()
{
  if(x)
    {
      print("hi");
      x = false;
      StartCoroutine(UpdateX());
    }
}

private IEnumerator UpdateX()
{
  yield return new WaitForSeconds(1f)
  x = true;
}

Nah I can't. My purpose for the code is to prevent inputs from overlapping. Since in 1 frame, there are 2 scripts that make use of controller inputs that trigger the same function, it tends to overlap. That's why what I did was in the latter script that should run, I placed the inputs for it on cooldown for a short period just to prevent it form overalpping

#

So basically, I want the coroutine to start first

Yes, you can use a format string to display the mass: text.SetText(rb.mass.ToString("F2")).
Adjust the number after the "F" to show more or less decimals

Hello, Why does agent.remaining distance always returns 0? Has anyone ever encountered such thing? There's no errors, no issues with the gameObject and the target, the agents are set correctly

if i have multiple colliders can i know which one was triggered?

timid crater Apr 14, 2023, 11:27 AM

plucky fractal if i have multiple colliders can i know which one was triggered?

Attach a script to the game objects that has a collider and use debug.log("Something " + gameObject.name) in a ontriggerenter method

plucky fractal Apr 14, 2023, 11:29 AM

#

well yes, but if i have one on right and one on the left can i know when the left one is triggered?

#

or should i make defferent objects per side

simple egret Apr 14, 2023, 11:29 AM

#

OnTriggerEnter, you can't

timid crater Apr 14, 2023, 11:30 AM

#

plucky fractal or should i make defferent objects per side

You can't use multiple colliders on the same game object

simple egret Apr 14, 2023, 11:30 AM

#

Probably, with each one having a script that relays which one collider to the same script

#

And you can use multiple colliders per object

Would they all fire?

If they have the exact same bounds, yes

Group the colliders by meaning on child objects

#

so if three colliders are all hitboxes, put them all on a child object

#

and add a component that reacts to collisions accordingly

Hey, anyone got any idea how I could make the highlighted tiles on movable spaces for the rook look better? I'm tryna figure something out but cant get something looking good as my artistic skills is non existent

Outline shader maybe

mighty juniper Apr 14, 2023, 11:40 AM

i actually tried that one with the chess pieces but for some reason it didnt work that well, when i tried it on pieces it wasnt great

steady moat Transparent Red/Green ? Arrow ? Single Dot ? Transparent Mesh ? Single Case ?

thing is right now, it doesn't change the actual tiles as its one prefab, its a square just above, and i tried transparency but its hard to see on white tiles. A singular dot could be a good idea actually

mighty juniper Apr 14, 2023, 11:44 AM

timid crater Oh I see

this is what i mean. I tryed following his thing exactly but i just couldnt get it right

heady iris Apr 14, 2023, 11:44 AM

very low poly models will not play nice with an outline shader

at least, ones that work by pushing faces out along their normals

I'm not sure but I think it might be a problem with the UV

I know of a good HDRP outline custom pass

#

not sure about URP tho

mighty juniper Apr 14, 2023, 11:46 AM

#

Yeah I only really know the absolute basics for shader graphs to be honest, never really dove into it much

heady iris Apr 14, 2023, 11:46 AM

#

What you COULD do is make a separate mesh for the outline

#

do you know much about Blender/3D modeling in general?

mighty juniper Apr 14, 2023, 11:47 AM

#

i mean its not really a problem, i dont really need an outline anymore for pieces. It was just an idea for the tile highlights

mighty juniper Apr 14, 2023, 11:47 AM

#

heady iris do you know much about Blender/3D modeling in general?

I've tried it, but im not exactly great at it

#

this is what i have for highlighting pieces now on mouse hover

#

which looks fine so im not bothered about changing that

heady iris Apr 14, 2023, 11:48 AM

#

ooh yeah, that's nice

#

Also, if you used smooth shading (when exporting the models), the shader would work

#

my understanding is that, to make sharp edges, you have to actually make the faces separate
