Yes

chilly surge
#

That's even easier. Set the whole board to zero except the last k elements being -1 indicating they are mines. Fisher Yates shuffle the last k elements, that's it.

#

Zero allocation, only k random calls and swaps.

vestal arch
#

why wouldn't it be

#

but generally you wouldn't have that many mines

fiery steeple
vestal arch
#

because usually there aren't that many mines in a 10x10 board

fiery steeple
vestal arch
#

also the amount of mines is usually fixed, not random

vestal arch

yeah

google's easy difficulty has 10 mines on a 8x10 board
minesweeper.online's easy difficulty has 10 mines on a 10x10 board

chilly surge
somber tapir
#

also the first field is never a mine, the mines are generated after the first click

vestal arch
chilly surge
#

I don't see how that's different

vestal arch
#

if you set the mines then shuffle, you'd have to also reposition the actual tiles

chilly surge
#

You put empty tiles all the way up, except the last k tiles being mine tiles, and do the exact same algorithm

vestal arch
#

shuffling first then setting the mines would let you avoid that, no?

vestal arch
naive swallow
fiery steeple
chilly surge
#

Reposition while shuffling then.

naive swallow
#

But you can still make a perfectly serviceable Minesweeper with just pure random placement

vestal arch
chilly surge
#

Yeah I mean, if this whole conversation is about the easiest way, then who cares about 100 allocations.

vestal arch
#

im not talking about adding allocations though

chilly surge
#

If we are going down the optimization route, the way I described would involve zero allocation and only k randoms and swaps, regardless of n.

vestal arch
#

...with those swaps involving repositioning gameobjects

#

i'm only talking about removing that last part

chilly surge
#

I don't get it, if you can "shuffle pure data first then position the game objects correctly at once" then why couldn't you also do the same thing but with my algorithm? Well, I'm not invested enough in this conversation tbh, seems like you guys have something already.

vestal arch
#

the gameobjects already exist

#

i am referring to your algorithm - in fact, i suggested a very similar thing

fiery steeple
#

Also I have another question, how to make my grid centered on the screen please ? I tried to change the pivot point of my tile to the center, top right and bottom left but my grid is never centered 😬

vestal arch
# chilly surge I don't see how that's different

this is the change im referring to

  for (int i = 0; i < k; i++) {
    target = random(i, n);
-   a[i] = -1;
    swap(a[i], a[target]);
+   a[i] = -1;
-   a[i].position = i;
-   a[target].position = target;
  }

#

instead of setting mines and then shuffling them into the board, you would shuffle the board and set the mines to first k Tile refs

Hey guys! i have a problem that i dont know how to solve. I have script that handles all my inputs
onFoot.UseItem.performed += ctx => { if (!playerUI.isInventoryOpen) useSelectedItem.UseItemInHand(); };
like this, when i press lmb it calls function from another script

{
    ItemSO itemSO = inventoryManager.GetSelectedItem(false);//what item is selected
    if(itemSO == null)
    {
        Debug.Log("No item selected to use.");
        return;
    }
    ItemSO selectedItem = inventoryManager.GetSelectedItem(itemSO.isUsable);//this reduces item quantity on use
    if (selectedItem is IItemUse usableItem)
    {
        usableItem.UseItem();
    }
}```
and from scriptable object script it gets UseItem of that SO
```public void UseItem()
{
    // Implement the logic for using the seed item here
    Debug.Log("used");
}   ```
ill try to be as clear as i can, i need to check in UseItem for canPlant bool from my plantingmanager script, so if i can plant than i will use the item, but i cant get a reference in my SO to plantingmanager, if i will do it in my UseItemInHand, then every object even if its not a seed will have a check on canPlant which i dont want because i will have items other than seeds. i propably could just use old unput system and in every item use script i would wait for lmb input, but i wanna do it with new input system. I hope i was clear enough and at least someone can understand what im saying.

Why not

#

This seems like a perfect use case

The alternative is to pass in some kind of context to the game world in UseItem or injected into the SOs at some earlier point.

I have an issue where my character uses root motion to do a dodge roll, but it doesnt seem to move the character controller.

(the animator and CC are both on the parent gameobject so thats not the issue).

#

You would want to disable that and the CC probably during the roll

deep pond
#

Yes the roll code is in the same code as the movement.

#

And I already do disable the movement when rolling

# 
if (isRolling) return;
leaden ice
#

How about disabling the CC when that happens too

deep pond
#

CC.move()

leaden ice
deep pond
#

what

#

you have to use root motion with the cc

somber nacelle
#

are you sure about that? because doesn't the root motion mean the animation controls the movement of the transform?

deep pond
#

skip to 7:10

#

apparently it causes glitchy movement

leaden ice
#

i.e. is Vector3 deltaPosition = animator.deltaPosition; this value as you expect?

deep pond
#

which means theres eomthing wrong with the deltaposition

leaden ice
#

right so it sounds like your animation simply doesn't actually move the root object

deep pond
#

think so

#

But the mesh

#

Actually moves

#

uknow?

#

jeez

#

yeah your right its the animation itself

#

In the animation I was moving the "torso" bone (which moved the whole character so i thought it was the root)

#

ihi quick question how come i cant see my scene until i go into game mode game mode bottom right

Screenshot_2025-06-03_165958.png
somber nacelle
#

not a code question. but it is because your scene camera is far away from the contents of your scene (excluding the canvas which it is focused on).
double click an object in the hierarchy to have the scene camera move to focus that object

bitter finch
#

ah ok it would be design then im assuming thought it was a bug in code

somber nacelle
#

it would not be a design issue either. it's just a general misunderstanding of the editor. #💻┃unity-talk is typically the place for questions like that.

bitter finch
#

ohhh ok ty

naive swallow
bitter finch
#

yeah i just realized that lmao since this isnt the right channel should i ask how to fix my issue in unity talk?

opaque vortex
bitter finch
#

i just cant figure out thebest way to make it so my sprites and what shows on camera fit the giant canvas unity made and if thats worth it

naive swallow
#

Sprites shouldn't be on a canvas

#

The Canvas should be for UI elements only, and things that aren't expected to move much

bitter finch
#

oh theyre not i meant the giant white outlined area

#

idk what the name is

naive swallow
bitter finch
#

wait so then why do i get a giant canvas for the game anyway if sprites cant go inside that area

vestal arch
naive swallow
#

You make the game in world space

#

you put the UI on the canvas

bitter finch
#

yeah i just feel buggered that that canvas isnt overlapped over the worldspace for me to see where everything lines up

#

but alr ty for educating me on that principle lol

vestal arch
#

it wouldn't really make sense since it an overlay canvas doesn't move in worldspace

naive swallow
bitter finch
#

mm i honestly just wanted the text to go about under the characters but still be ui buttons so i dont need to put them as sprites

#

so i see that too

or, to make it simpler. Can anyone help me on how to procedurally animate one axis, i have the target and the bone that needs to point all setup. i just need to figure it out

Can anyone test my movement code and give feedback on it? btw if you do the map has to be the layer "Ground"

you'd be better off making a WebGL build of your game and asking for feedback on the movement.

I want to render the main camera at a lower resolution using a RenderTexture, but I don't want to display it through a UI Canvas with a RawImage. I assume it's possible to draw the result directly on screen, since the PixelPerfectCamera component seems to do this without using any UI. How can I achieve the same effect manually?

leaden ice

Nothing specific, I just want to know if it's possible.

you can use renderer feature with URP and create a fullscreen effect

Hi everyone

round violet
#

how can I scale the touch input delta with the screen res to have a independent touch drag sensitivity ?

#

closest i got is dividing touch delta input with screen res

fiery steeple
#

Hey, is there a better way to handle out of bound indices for neighbors of my Tile in a Minesweeper game without using alot of if statements ? Like would it work with the ? operator for instance or something else ?

leaden ice
#

IsInBounds(coord)

leaden ice
fiery steeple

You'd have to show your existing code so there's something to compare with.

round violet
leaden ice
round violet
#

i dont see how this would work, higher res will mean higher speed

leaden ice
#

The res is already factored into the delta

round violet
#

the bigger the screen, the highest speed

leaden ice
round violet
#

so afaik delta isnt independant to the res

round violet
fiery steeple
leaden ice
#

It's literally 4 if statements

#

Or rather 4 conditions you combine with && or ||

#

In the time it took to ask the question you could have written it

#

It's just if:
x < 0
or
x > maxX
or
y < 0
or
y > maxY

No?

fiery steeple
vestal arch
#

no that doesn't work - it'd have to be the subscript itself being checked, which isn't a thing

null could work like that, outofbounds does not

I don't understand why you would need to check 8 things

#

It's only 4 checks

#

We're talking about a bounds check I thought

fiery steeple

oh yeah makes sense, I thought about when a cell is in a corner but yeah checking 4 directions would be enough to handle all cases 👍

leaden ice

Oh here's the cute way actually lmao

fiery steeple
#

People call me crazy for not going straight to the solution I have in mind, while doing this makes me and other people trying to help learn something new too 😄

vestal arch
#

you aren't actually using vector2ints though, are you lol

#

this is part of its own contained system that you aren't using, so now you have to sync them - seems like a lot of work to pawn off a single if check imo

fiery steeple
vestal arch
#

were you not using a 2d array?

fiery steeple
round violet
#

whats the macro to know if its a dev or release/shipping build ?

vestal arch
fiery steeple
vestal arch
#

im confused, do you have both the Vector2 and the 2d array to keep track of the position of each tile?

fiery steeple
#

in case I need to use

vestal arch
#

yeah ok i see what's going on, it's basically a reverse mapping isn't it

fiery steeple
#

I have no clue 😄

vestal arch
#

you have a mapping of 2 ints to each Tile and each Tile also has its key, those 2 ints

#

the disconnect is in how those 2 ints are represented - separately for the 2d array, and as a struct Vector2Int within each tile

#

and also how the bounds are defined - by the length of each dimension for the 2d array, whereas with Vector2Ints the bounds would probably be represented with a RectInt as you say

#

thonk could be a dict with try get and no need for bounds checks...

#

but yeah you have 2 systems in play but they aren't overlapping, they have separate responsibilities, so not really an issue

fiery steeple
vestal arch
#

what's with that grid

#

is that.. not the same as tiles

#

also wtf why is minesSpawnChances a Vector2Int lmao

#

eh whatever if it works it works shrugsinjapanese

fiery steeple
#

grid[] is data part of the grid, while tiles is the array containing the Objects themselves

#

like the visual part

vestal arch
#

doesn't seem like they really need to be separated

vestal hornet
#

What kind of project structure do you guys use/like. I'm currently basing it on modules, but i noticed that each folder will have the same folders like scripts, prefabs, shaders etc. I could have the like Assets/Scripts, Shaders etc... but i feel like there will be more coupling this way. Thoughts?

latent latch
#

If you're familiar with namespaces then follow a similar convention using them for your scripts, as for unity assets there's plenty of ways to go about it but most of the time it depends how you're constructing those objects from those assets

#

Like understanding the difference between a global material you would constantly use between objects, and more those specific to a prefab.

chilly surge
#

Organizing by type and organizing by feature are the two common ways. Personally I believe organizing by feature scales better.

latent latch
#

Big problem with some of the Unity asset architecture if you do just want a single instance of it, but unfortunately you need it to live in some directory.

last quarry
latent latch
#

Being able to embed materials or SOs would be a gamechanger

last quarry
#

You typically want as little embedded in a scene as possible.

#

You can embed mesh data in scenes but this is highly discouraged

latent latch
#

Yeah but I've some projects where I do have a directory per prefab because it has dependencies on 4 materials and a dozen SOs

#

would be able to cut it down and just have a directory of prefabs

last quarry
#

You could store the materials on the SO

#

And all the SOs in one asset file

#

With AddObjectToAsset

Almost all runtime code is in one assembly, and the only attempt at decoupling is this

B76FF7E9-AD34-4F22-B5EE-61D179C2AD75.png
#

YMMV but I've found that codebases that try too hard to be well organized and decoupled end up achieving the opposite catshrug

steady moat
#

Decoupling is usually made for maintainability in context of scaling application.

#

With multiple people working together on a considerably long timeframe.

last quarry
#

Well ymmv but again, I've found that the opposite was achieved by trying to centralize the codebase around some decoupling system.

chilly surge
#

You can definitely go overboard whether that's code structure or file system structure, but that doesn't necessarily mean going free style is going to work out fine.
Additionally it matters a lot more in a team environment than solo. With no discipline and everyone doing their own things, it gets out of hand real fast.

last quarry
#

You end up with everything having completely needless dependencies

steady moat
#

I have seen codebase with multiple script at 10k+ lines where you had possibly 100+ intertwined concept.

#

By example, the inventory was baked directly in the player.

last quarry
#

Yeah I think about it more on a per-system basis rather than taking the codebase as a whole

steady moat
#

I mean, we can simply look at what you have and find multiple case where what you did falls apart.

#

Obviously, in your case it works.

#

This is what matters. As long as you are able to navigate situation where you need to refactor it might be fine. (In a solo context.)

chilly surge
#

In a team environment, for the player and inventory example, even if you know these two are hard coupled in the project and you would never need to decouple them (which is a very fragile prediction about the future), just merely separating them into two files already provides many benefits, eg less merge conflicts when multiple people are working on this part of the code base at the same time.

last quarry
#

Well of course 🙂

#

But you're never going to fully decouple the player and the inventory

steady moat
#

By example, you might want to use the same system for loot

last quarry
#

Which I have

steady moat
#

So, you did that. Which is beyond what you were suggesting

last quarry
#

Yep. Thinking about dependencies on a system-by-system basis, instead of hard rules on the codebase as a whole.

steady moat
#

This is usually what people means when doing healty seperation of concept.

Or improvise and make your treasure chest immortal player objects you can interact with

last quarry
#

Bethesda-ass solution

last quarry
# steady moat No idea what you mean by "hard rules".

Once upon a time I worked on a game codebase where everything was structured according to the PureMVC framework, which is based around a messaging system.

Every call to another object went through a message instead of through a method call

#

Because everything needed to be registered, everything was dependent on this central system. Self-initialization was simply not a thing. Everything was highly reliant on call order. Debugging was hard because call stacks were super long.

steady moat
last quarry
#

Works pretty well in web dev yeah

#

Even though the kids complain that it's outdated 🙂

thick terrace
#

MVC can still be useful for UI if you have a lot of it!

last quarry
#

I've tried it once. Wasn't a disaster but felt kinda pointless maybe

#

Might be better with UI Toolkit

latent latch
#

On topic of the inventory/player relationship and MVC, ideally the inventory shouldnt know about the player and only invoke events upwards, but half the time I can't be bothered and just do bi-directional references

#

Similary with active elements like slots

#

Having the code decoupled is fine, sure. But having it decoupled completely via events is just overkill

last quarry
#

You'll probably know from the start that inventory can't rely on player so that's not a good dependency to make.

But for the most part keeping it simple makes refactors easier.

I am trying to add a waypoint that indicates the location of an area of the map of my game using a canvas with screen space camera and dragging the main camera to the render camera and with an image as a child that contains the arrow sprite that will appear on the map but I don't know why nothing appears, the sprite appears as if it were outside the map, I don't know why it doesn't work, I have the objective assigned to it correctly too, with the transform.

My main camera is orthographic and contains a cinemachine brain with a virtual camera that follows the player

#

And now I Will send the code

# 
using Cinemachine;

public class Waypoint : MonoBehaviour
{
    public Transform objetivo;
    public RectTransform arrowUI;

    void Start()
    {

        camara = FindObjectOfType<CinemachineBrain>().OutputCamera;
    }

    void Update()
    {
        if (objetivo != null && camara != null)
        {
            Vector3 screenPos = camara.WorldToScreenPoint(objetivo.position);

            // Ocultar si el objetivo está detrás de la cámara
            if (screenPos.z < 0)
            {
                arrowUI.gameObject.SetActive(false);
                return;
            }

            arrowUI.position = screenPos;
            arrowUI.gameObject.SetActive(true);

            // Calcular dirección y rotación
            Vector3 direccion = screenPos - new Vector3(Screen.width / 2, Screen.height / 2, 0);
            float angulo = Mathf.Atan2(direccion.y, direccion.x) * Mathf.Rad2Deg;
            arrowUI.rotation = Quaternion.Euler(0, 0, angulo);
        }
    }

For screeen space camera canvases you basically just use the world position of the object directly. It doesn't use screen space coordinates (confusingly enough)

i.e. pretty sure arrowUI.position = objectivo.position; would be more correct

but, all i wanna do is get something to look at another but only on a certain axis, like a pivot

leaden ice
compact carbon
#

i only want it to look at it with ONE axis

#

ive tried thost

leaden ice
#

still very simple

#

you're just skipping a step

#

you need to create a coplanar point first

#

then look at that coplanar point

compact carbon
#

how do i make a coplanar point?

leaden ice
#

for example, for rotating only on the y axis:

Vector3 lookAtPosition = whatever;
lookAtPosition.y = transform.position.y; // look at a point on the same x/z plane
transform.LookAt(lookAtPosition);```
#

This works well for world axes. If you need some arbitrary plane you can just use Vactor3.ProjectOnPlane to project your look direction vector on the plane then construct the rotation with Quaternion.LookRotation

compact carbon
#

but that wouldnt stop the x and y from also looking, correct?

leaden ice
#

I'm not sure what your question is asking

#

this will rotate the object on the y axis only to look at a point

compact carbon
#

is there any way that u can make an example of this in unity or sm, im not understanding this fully

compact carbon
leaden ice
#

that's all my code example is doing

#

(the green and red are axis markers)

compact carbon
#

oh forgot to mention, this is a pivot, so it pivots to look at something

leaden ice
compact carbon
#

i want the pivot to look at the grapple bar

leaden ice
#

what is "the pivot"?

compact carbon
#

the watch claw

leaden ice
#

i see

#

so you actually do have an arbitrary plane you're dealing with

#

you can do this in one of two ways

#

but the actual code depends heavily on how the object hierarchy is laid out

compact carbon
#

it has a root, and the actual bone for it is at 0,0,0

#

on the rotation

leaden ice
#

so I can understand the orientation of the objects better

compact carbon
#

1 = the pivot

#

2 = root

#

they are literally in the same place and rotation lol

#

though the root has the script in it

can anyone help with this missing prefab error I'm experiencing on linux? I am new to Unity but when running on Windows the sim worked perfectly fine with the maps being loaded but on Linux there are errors.

image.png image.png
leaden ice
# compact carbon

ok so what you want here is to rotate on the root's right plane basically.

Something like this should work or get you close at least:

Vector3 direction = directionToGrapplepoint; // however you get this
Vector3 planeNormal = root.transform.right;
Vector3 projectedDirection = Vector3.Project(direciton, root.transform.right); // project it on the plane.

Vector3 upDirection = Vector3.Cross(projectedDirection, planeNormal); // I _think_ this will do it.
transform.rotation = Quaternion.LookRotation(projectedDirection, upDirection);

but also you can't exactly pass components around like this afaik

why are you generating hitboxes dynamically?

'MB' is a variable but it's used like a type

Maybe this is what you want?

void CreateHitbox(GameObject theObj, List<MonoBehaviour> scripts) {

Seems good so far, but... well I've already made an entire game but I haven't screwed this much with dynamically applying scripts so sorry if this is a stupid question, how would I even make that list in the first place? Because I have this....
public class ATTACKMODApplyBleed : MonoBehaviour{[...]}
new List<MonoBehaviour> { ATTACKMODApplyBleed }
ERROR: 'ATTACKMODApplyBleed' is a type, which is not valid in the given context

the list would be the script

im pretty sure

ig

leaden ice

?
But how would I make a list of MonoBehaviors/scripts like I want to use?

leaden ice

you need the direciton vector, not the target position

leaden ice

Vector3 planeNormal = transform.parent.right;
Vector3 direction = target.transform.position - transform.position;
Vector3 projectedDir = Vector3.Project(direction, transform.parent.right);```

i said the script was on the root

leaden ice
#

gotcha

#

Vector3 direction = target.transform.position - transform.position;

#

you still need to do this

# 
Vector3 planeNormal = transform.right;
Vector3 direction = target.transform.position - transform.position;
Vector3 projectedDir = Vector3.Project(direction, transform.right);```

alright

ima check it now

WatchBone.transform.rotation = Quaternion.Slerp(

For the moment change it to just:

WatchBone.transform.rotation = lookRot;```
#

we'll add the slerp back in later

compact carbon
#

ok

its almost there

#

its just on the wrong axis lol

leaden ice

can you show what it's doing?

compact carbon
#

do u know whats happening

leaden ice
# compact carbon

hmmm that's odd... are there other scripts or anthing on the objects that are childre of the pivot?

#

At the very least the pivot should be pointing towards the point.

compact carbon
#

ye, just the actual bone, i made it a parent to make a pivot that faces the right way

leaden ice
#

is there IK or something involved here?

#

YOu are saying bone

compact carbon
#

no Ik

#

i just made the bone a child of a pivot cuz that way i can have the pivot at 0,0,0 but the bone is at 0,90,90

#

to face the right way

compact carbon
leaden ice
#

Can you show the pivot object selected again? It really just looks like maybe I was mistaken about the orientations

compact carbon
leaden ice
# compact carbon

Like can you show these screenshots but with the hierarchy in view too

compact carbon
leaden ice
#

ALso is WatchBone the pivot?

#

Or something esle?

compact carbon
leaden ice
#

Because my code assumes WatchBone is the pivot

#

At this point I would start doing Debug.DrawRay with projectedDirection and upDirection

#

to make sure they're being calculated properly

compact carbon
#

nothing is popping up i dont see it

#

would it be drawline?

#

huhhhhh

its drawing it at the center of the scene

ocean mirage
#

hi, i have a problem and cant solve it, maybe someone can help me.
player and enemy use both the same prefab like fireball for attacking each other. before the abilites launch, i give them a tag with it, that the ability knows who to collide with.
but when many enemies are attacking and i also atttack at ("kinda") the same time the tag get changed while flying or the projectile starts right away with the wrong tag and explodes instant on myself or the enemy hits hisself.

solution right now is, i have 2 prefabs, 1 fireball for the enemy and 1 for the player.
i wanna know if there are another ways to do it.

naive swallow
#

What is the difference between the two prefabs currently?

ocean mirage
#

fireball? nothing

naive swallow
#

So why are there two different prefabs?

ocean mirage
#

yeah but why does it work tho

#

i just tryed it and then it worked

naive swallow
#

tried what

ocean mirage
#

simple copied the ability

#

gave 1 the player and 1 the enemy

#

no more wrong collisions

naive swallow
#

Okay, and what are the differences between them

ocean mirage
#

they are differently named xd idk 😄

naive swallow
#

Are you using the name for anything? Do you have any code that checks that?

ocean mirage
#

no i dont make that

#

hmm u would need many things

naive swallow
#

So then what is the thing that you are checking to determine which one it is

ocean mirage
#

seralizefield, so i set it up in the editor

naive swallow
#

No, what is the code doing that is determining which fireball is which

ocean mirage
#

the fireball gets called from either player- or enemycontroller with a tag attached. so the fireball knows who to collide with

#

did i understand u right?

naive swallow
ocean mirage
#

theres 1 string tag in an ability and i set them depending on which controller called it

naive swallow
#

which you said there weren't any

#

If there's a tag that determines who cast it, you can set that after spawning the object from the prefab, then you don't need two prefabs

ocean mirage
#

what is the difference that im doin right now?

naive swallow
#

I don't know, you haven't mentioned what you're doing right now until I wrestled it out of you over ten minutes

ocean mirage
#

ah maybe i need to set the tag after it spawns instead of before

naive swallow
#

You can't set a tag before it spawns, it doesn't exist yet

#

you're changing the tag of the prefab

#

which would mean, the two prefabs have different tags

#

and are therefore not the same

ocean mirage
#

why i cant set a tag before it spawns. its a seralizefield gameobject, so i can call methods there without spawning it, cant i?

naive swallow
#

Spawning creates the object. How are you going to set any data on that object before it exists

ocean mirage
#

thats interesting and maybe the solution

naive swallow
#

Instantiate creates a clone of the prefab and puts it in the scene

#

The prefab object never actually exists

#

Any functions you're calling on it are changing the prefab

ocean mirage
#

understood

#

i try it - thank u so much

I'm building a 3D multiplayer mech game with a top-down perspective. Each mech is able to choose its loadout at the start of a match, and then it'll have those items equipped throughout the match. When I'm structuring my Robot Prefab, what principles should I be using to align with best practices? Specifically, I have a mesh for my Robot, but it needs to hold a gun - where should the object that represents the gun sit? Should it be a child of the Hand object inside of my Robot mesh? Or should it be a child of the "Robot" object? And then its visual is updated/rotated to match the location of the hand as it moves?

#

My understanding was that it's best to separate logical and visual elements, so my hunch was to create a PrimaryWeapon object as a child of "Robot". But I'm getting a little...brain-tied thinking about which objects should be responsible for which logic.

naive swallow
steady moat
naive swallow
#

You'd make the weapons be sibling objects that can easily be swapped out and not muck with the visuals, then you'd just need a script that knows which object the hand should be

fallen current
#

Wait, sorry, sibling.

#

Interesting, so you propose that every weapon is a sibling of one another, with a common parent.

naive swallow
fallen current
#

And then we toggle on/off which weapon is active?

naive swallow
#

ParentConstraint makes the actual parent hardly matter

fallen current
naive swallow
# fallen current What do you mean by that?

As I said, Parent Constraint makes the object move as if it were a child of something without actually being a child of it. So you could have the weapon anywhere in the hierarchy and just use a parent constraint set to the mech's hand

#

and you can set the offset and whatnot as well

fallen current
#

Got it, interesting.

naive swallow
#

If there's somewhere you'd prefer to put it because you don't want it to be in the hierarchy of the visuals, you can put it wherever makes sense for your workflow without worry

fallen current
#

Yeah I'd probably store it in the Robot object itself. Given that multiple players will be editing their robots on the screen at once.

#

And if a player drops out, that robot, weapons, etc. wouldn't exist.

naive swallow
#

Yep. And if there's a mechanic like looting weapons from destroyed bots, you could have the weapons be outside of that hierarchy so they'd still exist when the robot object is destroyed. It's a handy component

fallen current
#

Got it. Interesting ok!

naive swallow
#

Most of what it does can be solved by juggling parent objects, but doing that makes it a lot easier to lose track of the object or accidentally destroy it. It's not really any new functionality, but great for organization purposes like this

fallen current
#

So question about that then. I want to create a structure - I think - that allows the RobotController to activate "FirePrimaryWeapon(target)", and then the PrimaryWeapon fires a projectile. Naturally every weapon has different traits - damage, projectile speed, etc. My assumption is that every weapon should maintain knowledge of its projectile traits, and when spawning a projectile, it passes in the damage, speed, etc. (The projectile itself manages any unique movement)

So how would I build that programming structure to pass in the necessary damage to the PrimaryWeapon class? My first hunch was on Awake of any weapon, update the stats of its parent.

So I have a PrimaryWeapon class with a bunch of fields and a method called FirePrimaryWeapon(target) which is called by the RobotController when the player clicks the mouse, and a method called "UpdateWeaponStats". And then I have a Wep_Rifle class that sits on the actual Rifle prefab (a child of PrimaryWeapon) that, on Awake, calls UpdateWeaponStats(damage, speed, prefab, etc.) of its parent object.

#

But I have a hunch that...there's an easier, better way to accomplish this.

#

Ehhhh. Wait. That wouldn't be great because it would prevent me from creating unique firing traits - like burst fire or a flamethrower, etc.

leaden ice
#

e.g.

[CreateAssetMenu(...)]
public class WeaponInfoSO : ScriptableObject {
  public float reloadSpeed;
  public float shotsPerSecond;
  public float projectileDamage;
  // etc...
}```
fallen current
#

I guess what I'm missing is: with Wep_Flamethrower a child of PrimaryWeapon, how do I activate Wep_Flamethrower's instance of "FireWeapon()"?

image.png
leaden ice
#

then your weapon script can be like:

public class Weapon : MonoBehaviouir {
  public WeaponInfoSO weaponInfo;

  void Shoot() {
     float damage = weaponInfo.projectileDamage;
     // etc.
  }
}```
steady moat
fallen current

fallen current
#

So if the player equips Rifle, I'll first disable Flamethrower, and then enable Rifle.

steady moat
fallen current
#

I will, yeah. And in a single match, the player will only be able to ever have a single weapon the entire game. Instantiation feels like it makes a bit more sense for that reason.

#

(They can't drop or pick up weapons)

steady moat
fallen current
#

Ok so my next question then is, how do I instantiate a weapon, ensure its position and rotation are set properly, and make its methods available to my RobotController class?

You should follower a course.

#

You are going to learn a lot which you are not seeing because you do not even know it exists.

#

Then things are going to make sense.

fallen current
#

Sorry, that was a poorly-worded question. I know how to instantiate a weapon - I'm going to do so inside of the PrimaryWeapon class and track it from that class. And make calls down to the weapon's Shoot() method that it overrides from inheretance.

#

Thanks for the guidance!

#

I have a completely unrelated question: When I first started developing in Unity, my scripts would stay as active tabs inside VisualStudio 2022 even between compiling. But it seems now that sometimes when I compile my game, or when I add a new script, VisualStudio completely clears out my open files, which is getting REALLY annoying. Even if I pin them, they close my open files.

#

Does anyone have a hunch why that's happening?

steady moat
#

Alternatively, you could delete the library folder (it can takes a while) and reopen the project.

fallen current
#

Thanks, I'll try these.

steady moat
#

Otherwise, keeping it updated or reinstalling might works as well.

Hi, I'm working on a VR game so I have a player object that has the camera and both controllers as a child. But if the player moves in real life they will no longer be in the center of the player object which can be a pain when I want to move the player to a specific spot. So I'm looking for a way to always set the players transform at their head for example.

fallen current
#

@steady moat @leaden ice Thanks for the help today, you both got me on the right track. I created:

  • A PrimaryWeapon script that manages the PrimaryWeapon, instantiates it on a HoldPoint object on the mech's hand, and then call the equipped weapon's Shoot() method
  • A Weapon class that defines a Shoot method, inherited by each weapon so I can GetComponent<Weapon>.Shoot() regardless of the weapon equipped.
  • A WeaponStatsSO that defines fields that weapons will use to define damage, projectile speed, recoil, reload times, etc.
  • A Wep_Rifle script that defines the unique shooting functionality of the rifle, overriding the Weapon.Shoot() class
#

And then I refactored my original primary weapon shooting code, ripped it out of the RobotController and put it in the Wep_Rifle script. Now the RobotController calls PrimaryWeapon.FirePrimaryWeapon() which calls Weapon.Shoot() and can shoot any weapon I attach to the PrimaryWeapon class.

#

The element I'm not quite sure about is the WeaponStatsSO. I'm calling it the way you mentioned Praetor, but I don't know if I'm using SOs to their fullest. It doesn't feel like they're providing me much more than what I'd write inside the class itself.

public class Wep_Rifle : Weapon
{
    private WeaponStatsSO weaponStats;
    [SerializeField] private GameObject projectileSpawnPoint;
    [SerializeField] private GameObject projectilePrefab;

    private void Awake() {
        weaponStats = ScriptableObject.CreateInstance<WeaponStatsSO>();
    }
    private void Start() {
        //weaponHoldLocation = GameObject.Find("RifleHoldLocation");
        weaponStats.projectilePrefab = projectilePrefab;
        weaponStats.damage = 10f;
        weaponStats.projectileSpeed = 50f;
        weaponStats.projectileKnockbackForce = 10f;
        weaponStats.projectileLifetime = 5f;
        weaponStats.lifetimeTimer = 0f;
    }

    public override void Shoot(GameObject _target) {
        // Move all of this logic to the weapon itself
        Debug.Log("Wep_Rifle Shoot(" + _target + ") triggered");

        // Calculate the move direction to aim at the currentTarget, or forward if no target is set
        Vector3 moveDir = _target != null ? (_target.transform.position - projectileSpawnPoint.transform.position).normalized : transform.forward.normalized; // FUTUREMAX This is going to need to be updated, because if there's no target, it will shoot out of the front of the gun - possibly at the ground.
        GameObject projectile = Instantiate(weaponStats.projectilePrefab, projectileSpawnPoint.transform.position, Quaternion.identity);
        projectile.GetComponent<DebugProjectile>().Initialize(projectileSpawnPoint.transform.position, moveDir, gameObject, _target);
    }
}```

You wouldn't need to create more than one Weapon class

#

unless you had behavior you couldn't capture simply from the data.

fallen current
#

I definitely do.

#

A flamethrower is going to be fired very differently from a rifle.

leaden ice
#

eh, possibly

#

not necessarily

fallen current
#

Though...yeah, I get what you're saying - it's possible the fire logic takes into account elements like "fuel", where a rifle might have infinite fuel. Then some logic that determines if fuel then fire.

leaden ice
#

regardless you definitely would need fewer classes. You don't need a different class for a rifle vs a pistol

fallen current
#

Right. I understand. So an SO is like a container that makes fields available in the Unity Inspector - and these fields are individually editable on every object with a script that instantiates that SO?

leaden ice
#

the MonoBehaviour script has nothing to do with it

cold parrot
fallen current
#

So from a practical perspective, do I place the SO on an object in the editor as an asset? Or do I add it as an asset inside of the Weapon script?

leaden ice
leaden ice
#

it lives in the project folder

#

like all other assets

fallen current
#

Sorry, I confused the terms Asset and Component.

leaden ice
#

the Weapon script simply references it

#

Components are the things you attach to GameObjects

fallen current
#

I know it's an asset. But it's not a component.

leaden ice
#

Assets are the things in the Project window

#

there's a very clear distinction

fallen current
#

Right. Got it, yeah that I understand fully.

#

I think we might be on the same page, but using different terminology. My understanding until now was that the only way fields appeared in the inspector is if you used [SerializeField], or used [CreateAssetMenu] explicitly inside of a script. But in your Weapon.cs example above, you instantiate WeaponStatsSO weaponStats (using my naming here). And you're saying that the fields defined in weaponStatsSO would be editable in the inspector?

leaden ice
leaden ice
#

TO do this you:

  • Create an instance of the SO in the project window through the Create menu
  • Set whatever data on it you want
  • Add the Weapon script to a GameObject somewhere
  • drag and drop the SO from the project window into the field on the Weapon script to set up the reference.
fallen current
#

Goooooot it.

leaden ice
fallen current
#

The SO script is defining what fields an SO has. And an instance of an SO actually defines the values for those fields.

leaden ice
#

yep

fallen current
#

Got it got it got it. Ok.

leaden ice
#

same as a MonoBehaviour really except instead of being attached to a GameObject it just lives as a standalone object in your assets folder

fallen current
#

My brain is expanding.

#

It takes some time to get back into the swing of OOP. That a single instance of a script (weapon.cs) can exist on multiple objects, each instance containing its own instance of the weaponStatsSO that defines the values of fields relevant to that weapon.

leaden ice
#

Sure - I think it's better to think of the weapon having a reference to a WeaponStats, rather than containing it

fallen current
#

Absolutely.

leaden ice
#

But yeah classes in OOP are always like "blueprints". YOu can and often do build many houses from that same set of blueprints

fallen current
#

Yup

#

Cool, thanks for the clarity.

frail oak
#

is it really not possible to calculate a path using a certain set of weights for navmesh cells?

#

the only way to weight the pathfinding algorithm seems to be to give it GLOBAL area weights which rebake the navmesh

#

and apply to all agents

rigid island
frail oak
#

I understand that's a global modifier

#

that sets "area" which is like a terrain type enum

#

not setting the cost for a specific run of A*

#

plus it's done as a volume, is it not?

#

I want to tag each cell used in the path of an enemy, and trying to do that with a bunch of cube volumes sounds horrible

rigid island
#

I suppose so , what do you mean for a specific run

#

Working with a mesh you are pretty much at the mercy of whatever unity coded in

frail oak
#

im trying to make flanking behavior and it seems nearly impossible

#

so say one enemy walks right at the player through the most obvious doorway

#

I want to add all those cells to an "extra cost" array but only AFTER its generated the full path obviously

#

then I want the next enemy to account for that as like a weight mask, which would suggest it to take a different door unless thats the only door

#

but it also can't account for its own path, it has to apply once it has its path

#

and I might want other enemy types to not care what this one is doing

#

if one soldier guy goes through a door, a dog type chasing enemy shouldn't necessarily decide it needs to flank

#

but if I have to use a global area weight, it will

#

plus these areas are defined by like, volumes it seems

#

that float on top of the navmesh and carve it kinda

#

I want the actual navmesh triangles/polygons to be the shapes, not try to place a bunch of cubes all over the map editing the baked navmesh and then removing them and all that junk

#

basically I just want to take an agent, and say "run A* to find the fastest path, but add a weight to any node that the same enemy class took recently"

rigid island
#

I think combining this, with a bit of tricks with surface/modifier you can get around some limitations of built in nav

frail oak
#

I saw that method but all that does is set the cost of a specific terrain type

#

which I don't really need

lean sail
frail oak
#

I need to dynamically set certain costs an a CELL BY CELL basis

rigid island
#

That's all done in the backend by unity , you'd have to make your own system

frail oak
#

what is o2n

rigid island
#

typo sorry shit mobile keyboard lol I meant own

frail oak
#

ah

rigid island
#

Maybe the a* pathfinding project but doubt the free version would have such a gesture

frail oak
#

well yeah, I think I DO need to somehow get a graph from the NavMesh and then run a custom A* on that and then do some other stuff to smooth the path

rigid island
#

unity navmesh is like "baking...OK here is a mesh" hence the name lol

frail oak
#

or maybe I can like, place a volume over each "doorway" that turns on or off, which carves the mesh but only in a smaller area

#

but then can I make certain "areas" only apply cost to certain units?

rigid island
#

Also navmesh links are a thing too they offer some level of control over connecting areas

frail oak
#

you can set a "walkable mask" but thats binary

#

can you make links have agent specific weights?

#

or agent-class specific at least

rigid island
#

Yea

#

Make agent type

lean sail
#

if you have 2 of the same agents though, i dont think this applies to what you want

frail oak
#

I think it might work bawsi

rigid island
#

might have to switch some types at runtime based on current needs

frail oak
#

the problem I have with terrains is that they are the same for every agent

#

like "water" area is 50 cost or something

#

it's 50 cost no matter what agent you are

#

you can disable an area for an agent in a binary way but that's not what I want

#

but if links can say, "add cost for soldier agent type but not dog agent type" or something like that

#

then that MIGHT work, though it would require me to determine what exactly is a link and what isn't etc

rigid island
#

same with modifiers it can apply specific costs to certain agent type

frail oak
#

and it probably wouldn't just be something I can easily bake

frail oak
rigid island
#

I think so yeah

frail oak
#

can you have a static volume that doesn't change the navmesh triangulation constantly

rigid island
#

But also you shouldn't be baking an entire level, I use multiple navmesh surfaces depending on use case

lean sail
#

a link is to connect 2 areas of your navmesh, if all you're doing here is adding a link then it's going to calculate that it can just move directly across a link. i dont see how this solves anything really.
the placing a volume over each doorway i believe is something i suggested once, and really I think doing that would be the easiest way if you want to stick with navmesh

rigid island
#

Links is useful for creating a connections between two points on navmesh without rebaking

frail oak
#

so it IS possible to have a static volume over a doorway that cuts up the mesh once at baketime and then just changes the area of a subset of the triangles for SPECIFIC agent types?

#

area is such a confusing word for this use case, terrain type whatever

lean sail
frail oak
#

I was envisioning it in the context of custom A* where I would be applying a kind of "mask" of tris to the cost function each time but I think agent type would work just fine honestly

#

enemy type A would coordinate/flank, but would not coordinate with enemy type B etc

#

which I think is totally workable, if I want a bunch of enemies to surround the player I just need to make sure they are the same agent type

#

and that wont affect the pathfinding of an enemy that is more agressive or whatever

#

the only other question is, how do I determine all the volumes that need to be triggered when an enemy pathfinds?

#

like if an enemy gets a path that goes through a door, but it hasn't gone through it yet, how do I then tag that door volume?

#

can you test if a ray intersects one of those volumes?

#

this is why I thought custom A* would be cleaner, you just directly mark the nodes

rigid island
#

gotta look better when I'm back but at least with links for example you can get the agent on it , probably same with areas / surface

frail oak
#

plus I dont have to manually place volumes

#

on it currently, but what about for an entire path?

#

I dont want 5 enemies to approach the same door and THEN split up as soon as one touches it

rigid island
#

The agent has info of its path

frail oak
#

and I could convert the path into a sequence of rays potentially

#

ok I am kinda seeing the issue with per agent TYPE

lean sail
#

a raycast wouldnt hit it, its not a collider. you also wouldnt have it active in the first place, this is something you'd need to manually figure out. if a volume is covering the path that you were walking on. The agent does store the path that it wants to take.
I do find it even more confusing what you actually want now. Maybe play around with navmeshmodifiers and volumes in your scene to see how it works because I feel like you think it's going to do something that it won't.

frail oak
#

what I want is a pathfinding algo where each agent marks nodes that it's using, and OTHER agents avoid those nodes if possible

#

but since it seems that I cannot directly access the pathfinding OR the nodes in Unity...

#

volumes is kind of potential hacky workaround

#

the potential issue with agent TYPE though is that it can't ignore weights it set itself...

#

like say agent paths to green X, which then would trigger this doorway volume. but then it hears the player fire a gun and updates its path, however since it already marked that doorway, it's avoiding its past self even though it should "own" that path

image.png
#

that's probably why I wanted agent specific weights

#

not just agent type specific

#

maybe it can then pathfind to the new location both from its current destination and its current location and append to its path if the new location is closer to its destination? idk how cost intensive that is

#

with custom A* I could have a list of agents, and each agent has a set of nodes, and then when pathfinding it creates a weight mask of all agent nodes EXCEPT its own

#

and I would be willing to attempt custom A* if I could figure out how to get a graph from the navmesh triangulation unity gives me...

rigid island
#

that's difficult to do since it's closed source / probably the c++ side

#

doing hacky shit is sadly the reality of working with a closed feature with its limitations

frail oak
#

how easy is it to create your own navmesh?

rigid island
#

the grid itself is pretty easy since there are so many articles/tutorials/example

#

I only personally did it with 2D though so I cannot comment on how to deal with elevations / slopes

frail oak
#

I mean, I think it would be possible to create a graph of triangle midpoints based on the triangulation

rigid island
frail oak
#

it's just like, the actual smoothing of it, wrapping around corners etc

#

I can find the midpoint of each triangle and make that a coordinate node

#

and then if a triangle shares two verticies with any other triangle, make an edge

#

but that graph is going to look very jagged

#

A* itself I'm sure will be easy enough, I just need to apply an extra cost to a list of nodes every time it's run

#

the hard part is making that path actually look sane

#

like, I understand graphs and pathfinding on a graph. but I don't understand making that path fit nicely in a big polygon

#

maybe it doesn't need to look sane though? lol

#

if the player has line of sight to an enemy its gonna change its behavior anyways

#

so as long as it's not TOO innaccurate to the actual geometry of the place...

rigid island
#

You might be overthinking it tbh

frail oak
#

I dont think so unfortunately

#

if I can't have agent-specific weights then an agent can be blocked by its own pathfinding

rigid island
#

I think with the function bawsi and I linked you(set agent cost) can be used to solve partial part of this problem if you still plan on using navmesh

frail oak
#

set area cost or set agent cost

#

because set area cost has the same global problem and I dont see set agent cost

#

I can't figure out how to reference the NavMesh in code

#

its global per scene right?

rigid island
#

I think it was , iirc you can now access the specific ones based on navmesh surface

frail oak
#

I think I found it im checking rn

rigid island
#

I'm on mobile rn its a bit of a pain to double check but yeah you can probably find that

frail oak
#

I think I got it

#

now I need to make the code to create a graph from this, which I think is at least simple conceptually...

compact carbon
frail oak
#

If I understand the structure of the triangulation correctly I believe I have printed every triangle in the navmesh

image.png image.png
#

I want to draw them in the game or something if possible, but idk if drawing 2K spheres will crash the game I guess we will see

mossy snow
#

no, you have made triangle soup

#

you need to use the index to determine which vertex to use

frail oak
#

thats what im doing, am I not?

#

im looping through indices in groups of 3

mossy snow
#

but not using the indices to look up the vertices, just using the ith index for the ith vertex

frail oak
#

oh so it has to be like

#

tri.verticies[indices[i]]

#

right?

mossy snow
#

yes

frail oak
#

ah ok thank you for catching that lol

#

whats the best method to draw like a sphere or something? DrawGizmos can do it but it applies to the scene view, when this information has not yet been generated

#

I just wanna see if I can calculate midpoints and see if they line up to the navmesh

mossy snow
#

draw a sphere out of what? the midpoints of every tri? DrawGizmos would work fine, just cache the points it should draw

compact carbon
#

alright i figured it out, kinda this code works when its the object is not a child of an object but not when it is a child, why is this?

transform.LookAt(new Vector3(target.position.x, transform.localPosition.y, target.position.z));```
#

btw this is code to look at an object on ONLY the y Axis

mossy snow
#

it's expecting a world pos and you're providing a weird hybrid point that uses world target x and z but local y which is an offset from the looking transform's parent

compact carbon
#

well that localposition i changed after i still didnt work after just inputted the normal .position, doesnt wanna work anyway

#

i tested, when the object that is doing the looking is NOT a child. It works fine, but when it is it just doesnt

#

it still looks at the object but doesnt do it one just one axis. it does it on all

mossy snow
#

if the looker is not a child, then transform.localPosition == transform.position

#

so you did something wrong if you "just inputted the normal .position"

compact carbon
#

even if i just put in localpos it still works when not a child

mossy snow
#

if looker has no parent, then
transform.LookAt(new Vector3(target.position.x, transform.localPosition.y, target.position.z));
is equivalent to
transform.LookAt(new Vector3(target.position.x, transform.position.y, target.position.z));

#

what are you trying to do exactly? You keep saying one axis but your code will potentially manipulate all 3 axis

#

you only want to rotate around y axis?

compact carbon
#

okay, got it to work, but now it only updates when im moving the camera

# 
var relativePos = transform.InverseTransformDirection(target.position);
relativePos.x = 0;
var targetPos = transform.TransformPoint(relativePos);

transform.LookAt(targetPos, transform.up);```
#

btw rotating on the Y was just for testing

guys i need help, it's been 4-5 months since i started learning unity and i feel like that i'm stuck in tutorial hell already, i've been taking GameDev.tv course since 4 months and i've been really making a progress,

however i don't see it that it fits my overall perspective as i want to build a TCG/CCG and I couldn't even find any useful course that would teach me the logic of building such a game (like deck building / in-game stores / PvP / Drawing cards / holding cards in hands / etc)

I tried different courses and resources yet none of them is really that helpful which made me feel like I'm stuck in tutorial hell

any advice?

leaden ice
urban summit
#

well you're totally right with that one, but i couldn't figure out the right programming logic for building a TCG/CCG like deck-building system, drawing cards, in game-store etc it's that what's preventing me from starting to make out my own game

leaden ice
#

you're mentioning three different systems there

#

the best advice I can give is that you need to focus on each thing one at a time

#

don't try to do it all at once.

urban summit
#

they all are part of TCG = Trading Card Game / CCG = Collectible Card Game, they all are about these type of mechanics, drawing cards, building decks, buying cards, holding cards in hands etc (this is the type of logic that i'm struggling with)

leaden ice
#

I'm aware they are part of that kind of game

#

my advice remains the same

#

you must tackle each system one at a time

urban summit
#

I see

#

well could you provide me a guidance? like a certain course or anything really?

#

even someone that has succeeded making his own TCG before

night harness
#

The biggest way to escape programming hell is being able to take a specific goal (eg. drawing cards) and deconstructing it down into the actual features required to make that work

-Held cards need to be stored somewhere (on a/the player?)
-Deck needs to be stored somewhere (on a/the player)
-Max held amount needs to exist
-Selecting a given amount of random cards from a deck
etc. etc.

then thinking about each of these features and determining what you don't know about programming that you need to know in order to achieve them

-How do i randomly select from a list
-How do i make other scripts reference eachother

etc. etc.

At that point you can start actually googling those things to get specific advice and learn

leaden ice
#

Besides if the game you're making can be boiled down to a tutorial that 50,000 other people have followed, well the game you make from that isn't going to be very unique or interesting then, is it?

urban summit
night harness
#

yes

leaden ice
#

that's just how problem solving in general works, yes.

night harness
#

you don't learn how to make games, you learn how to do the things that are neccasary to make games

urban summit
#

Thank you so much i didn't know that i should be looking at it like this, it's why i was stuck

urban summit
night harness
#

And because your learning these individual things, you compound knowledge that is super transferable for other future games

urban summit
#

one last thing to ask you about, which game phase should i start with? the gameplay, main menu, deck-building etc? or should i just pick up one randomly and go on with it till i finish it and pass to the next phase?

leaden ice
#

go with whatever you think is the most interesting to start with

west lotus
#

Start by having a shuffled deck of placeholder cards and being able to draw cards into your hand . Then you can build out your specific card rules around that

urban summit
#

Thanks guys!!! I really appreciate your help!!!

latent latch
#

totally start with designing cards with simple mechanics as that's the fun part

#

not so fun part is getting a nice arc and lerping motion when choosing said cards in hand

urban summit
#

I already have that one in mind, like i settled down the game concept, the logic, the mechanics, the main idea of the game, literally everything (even the creatures design i have couples of them in mind) the only thing is to start actually developing the game, and i agree i already had so much fun during this phase (like settling down the game logic and mechanics)

west lotus
#

The great thing and making a tcg video game is that you can actually make a physical prototype and playtest that

#

Before committing a single line of code

#

Thats what I would do

urban summit
west lotus
#

You sit down, design your mechanics and cards, then write them out on pieces of thick paper cut out the cards and start playing with friends

urban summit
#

ohhhh

#

i see

west lotus
#

You then realise whats fun whats boring whats completely broken. You re-work re-balance

urban summit
#

ngl that sounds pretty interesting and would help me develop a better mechanics for the game

urban summit
west lotus
#

Iterate until you actually have a really fun card game and then it’s just a matter of coding it up

urban summit
#

ngl your idea is genuinely interesting and pretty smart actually, it'll totally help me figuring out what game mechanics are more fun than the others before wasting time coding them

#

Thank you i appreaciate your help!

west lotus
#

Just make sure to playtest with actual people. Go to your local shop and listen to the feedback. Games should not be made in a vacuum

urban summit
#

yeah i totally agree with that, after all a TCG isn't gonna be a single player game it's game that you play with other people and having an immediate feedback on every mechanic i think of would be really helpful and would save me plenty of time

west lotus
#

Exactly. No point on working on flashy card animations and foil shaders if your underlying card mechanics are shit

#

And your first iteration is going to be shit

#

I mean no offence thats just how game design works

urban summit
#

none taken really i did work on a couple of projects while learning unity and i totally understand that lol

#

one last thing i want to ask, my plan is to make the game fully online, so while building the game should i be building it as an offline game then adds the online feature to it, or simply builds it fully online from scratch? i'm still an amateur in unity and getting a feedback on this would be hlepful

west lotus
#

Build it with online from the start

#

Much easier to add offline play to a online game than adding online to a offline game

Hello what's up ?
I try to make a card game like.
I try to follow this tutorial : https://www.youtube.com/watch?v=bsPUDjijjTo but using the Balatro system made by Mix and Jam (https://www.youtube.com/watch?v=I1dAZuWurw4) as the base.

I don't know how to apply datas on the card instantiated. The Balatro system already instantiate the cards on the board. On top of that, for each card created, I want to call the Setup method that replace the datas(visual, titles, etc) on the visual of the card.

On the course I follow it has this structure :
Slay_Card get the datas from a scriptable object with all the info (title, images...)
Slay_CardVisual apply the datas on the card.

Now I have 2 other scripts that are supposed to connect all the datas.

I've got this script, it need to get the actual card create but I don't know how :
public class Slay_CardViewCreator : Singleton<Slay_CardViewCreator>
{
[SerializeField] Slay_Card_Visual card_obj;

public Slay_Card_Visual Create_Card(Slay_Card card){
    Slay_Card_Visual card_visual = something to put here; <-- 
    card_visual.Setup(card);
    return card_visual;
}

}

and this test script, it get the scriptable object and call the Create_card method:

public class Slay_test : MonoBehaviour
{
[SerializeField] private Slay_CardData card_Data;

private void Update(){
    Slay_Card card = new(card_Data);
    Slay_Card_Visual cardVisual = Slay_CardViewCreator.Instance.Create_Card(card);
}

}

I try with Code copilot, chatgpt and every AI I found but that never work for me

Thank you

I think I found the solution (with Code Copilot)

round violet
#

is there a c# definition to know what type of build is running ?

#

like UNITY_DEVELOPMENT, UNITY_SHIPPING, UNITY_RELEASE

#

i dont see any of thse or similar in the scriptign symbol reference, this surprises me

chilly surge
round violet
#

why such basic macros dont already exist ?

chilly surge
#

How should Unity know what development/shipping/release mean?

round violet
#

other engine does, i assume it can read what params are passed when compiling domain

chilly surge
#

I mean, what's to say my game must follow a software cycle like that, or what if I want a different cycle like development/staging/prerelease/release?

#

The point is that you can define whatever symbols and set whichever one to active yourself, via plenty of options listed in that page, automatically or manually.

round violet
#

im fine by adding it myself, but its very common to have stuff enabled/disabled depending on build type so i was surprised it wasnt implemented in engine core

chilly surge
#

Unity has build profiles, each profile can overwrite whatever settings (including adding/removing preprocessor symbols), and you just switch between which profile you want active atm.

#

I guess you could say "Unity should automatically create 3 build profiles (dev/prerelease/release) for me, each with symbols already set" but 🤷, feels like something very minor.

round violet
#

it doesnt change what i just said

#

yeah, but not minor

chilly surge
#

To me "clicking creating a build profile and clicking adding a symbol" is pretty minor, and this is an one time thing per project so it's not like you have to do this on every build, but I guess we have different definitions of minor.

round violet
#

something used for most projects isnt a minor thing to miss IMO

you dont see doctors using butter knives for surgery

Probably a better comparison - doctors don't get dogmatic about the brand stenciled onto their scalpel handles

#

If it's sharp and sterile it's gonna do fine

#

Their hospital might have some sort of brand deal where they get all their equipment from one manufacturer, which means the doctors there use that one

but no one should have any sort of loyalty to it

Hello dearest unity community! Im using the tarodevs playerController in case you know that, and im trying to implement moving platforms (without parenting the player) and if tried it via calculating the platform velocity, and than syncing that to the player velocity, but thats just making my player shoot of the platform, all attempts at moving the player via transform or rb.transform resultet in jittering and im kinda going insane.. maybe someone had this issue before or can help me!

wait ill upload my crazy spgagetti modified version of the playercontroller anyways

in case anyone has tipps on improving the readability of my code hit me up, cause i feel like even tho ive tried my best to keep this clean it is getting out of hand once again

☁️ 🌈 Another Philosophical Best Practice Question: 🌈 ☁️

I'm designing a character animator whose animations need to be changed as the character moves around the arena. I can't use input values, because the directional input from the player will rarely match the local directions of the character on the screen (the camera is set at an angle, and the character often rotates to face other characters). So the CharacterAnimator needs the value of the character's "local" move direction. I see two philosophies here:

  • The CharacterAnimator should fetch the move direction of the character, so it grabs an instance of the RobotController and queries the RobotController for the moveDir of the robot.
  • The CharacterAnimator should allow objects to give it the robot's direction. So it creates a public method called "UpdateMoveDir" which the RobotController calls every frame to pass in the moveDir.

Can someone talk me through the two philosophies, and how they make/break best practice when it comes to object responsibility and performance?

soft shard
# fallen current ☁️ 🌈 **Another Philosophical Best Practice Question:** 🌈 ☁️ I'm designing a...

Personally, I think the latter approach might become a bit of a nightmare to manage if you have objects close to eachother that can both affect the players movement, or objects that affect the movement in opposing ways (one moves it left, and another moves it right, keeping the player in a weird "undecicive" state) - for that reason, I think the player should determine their own movement in the world, rather than the world determining the players movement - the player could use raycasting/physics queries like a spherecast to figure out if things around it should affect when it should stop or something

In the former approach, I dont think I understand the issue of updating animation variables to affect the animations that play, regardless of the input thats coming from, if those values are between 0 and 1, you can treat movement like a percentage or convert the input into local direction: https://docs.unity3d.com/6000.1/Documentation/ScriptReference/Transform.TransformDirection.html

fallen current
#

My brain is processing the second bit - "covert input into location direction" I think I understand what you're saying though I think I'd need to use InverseTransformDirection if I'm not mistaken. Because it's a top-down game, I need to convert world coordinates (W means "move this direction in the world") to local coordinates, because the local coordinates would determine whether the player is strafing, moving forward, backward, etc.

soft shard
#

Yeah imo I think systems should try to be as independent as they can be, so if they dont need to have public functions which change the logic, from other classes accessing it, its probably a good idea to keep it local - you can try inverse if you think it will be better for your situation, its nice that the API provides a few different options for converting vectors, and if needed, you can also flip the sign of the resulting vector

I'm trying to code a dialogue system for my game

a conversation is a list of lines, and each line holds needed information, like the plaintext of the message, whether it's incoming or outgoing, etc

Im struggling to decide how to store the pointer to the next dialogue line

In some cases, the next line will be set, in which case, easy. Next line is the next line in the list.

In some cases, I want to be able to randomly select one line of several

In some cases I need to select a line based on game state like amount of ammo remaining or something

In some cases I need to prompt the player to choose one of a few responses

unsure how to fold all of those cases together

leaden ice
#

You can try using an existing framework like NodeCanvas or build your own

calm flame
#

I'm trying to figure out how to build my own, my dialogue system is convoluted and morse code based and part of the primary gameplay loop, so a plug and play prebuilt framework wont work in my use case

#

Trying to figure out how to allow the same system to handle the different cases of how to proceed

#

Considering making like, an enumerator, with

  • set
  • random
  • conditional
  • playerChoice
#

unsure if a two-part system, with type and list of options stored seperately, is my best play

lean sail
#

the simplest way without making a complex system would probably just be through scriptable objects, each asset represents a line. Each instance has a list for next possible lines. Use an enum/inheritance to determine how the next one is decided

leaden ice
#

NodeCanvas is far from plug and play

calm flame
lean sail
#

if you use an enum, that "conditional" part you mentioned above would have to constantly be updated to handle new cases. if you use a base class and override the method it'll be a bit cleaner.
Though if this system grows large i can imagine it being a nightmare to see the graph here. You'd probably want some editor script to draw it for you

#

and then we add more features like editing it from the graph and you've built a complex system!

calm flame
# 
public class Line : ScriptableObject
{
    public string plaintext;

    public messageDirection direction;

    public List<Line> nextLines = new List<Line>();

    public nextLineType nextLineType;

}```
#

How can I make it so when I hit the plus sign to add a new line to the conversation, it allows me to edit the lines from the same inspector rather than prompting me to drop in a line item?

#

desired result is something like this

hello does anyone know how to load levels in unity
Like i have a map with 3 levels
i want to load level 1 when this happens, do i use different scenes? or what

you'd need to learn how the SceneManager works btw

mint zenith
#

just answer pls

#

if u know

#

need answer fast

rigid island
#

I told you how, you call LoadScene with SceneManager

#

if you want to split it across different levels thats up to you and a game design question

mint zenith
#

so i can make one scene for each level, and i just have to add my player each time into each scene at the spawn position where i want it?

#

i think i understood it that makes alot of sense

rigid island
#

yes unless the same player is passed through the scenes each time or use ddol but those are diff topics

#

depends how you handle data

mint zenith
#

ye i understand what u mean

#

lowkey sounds way simpler then i overthought and overcomplicated that

#

data saving shouldnt be too hard

#

i found a way to handle that

#

but i just need to reuse the same player

#

or use tags

use tags for what?

for

just other stuff

why even have that object if you're not gonna use it

thats what its trying to tell you, its not a stupid warning..

I forgot why I have that 😄

Oh yeah I wanted to instantiate my tiles and have the parent be the gameObject "canvasCenter", and it complained and the solution I found was the InstantiateParameters as it was the thing it suggested if I remeber correctly

rigid island
#

"it suggested"

#

like AI ? cause this sounds like it lol

fiery steeple
rigid island
#

if you want them to spawn as child of canvasCenter then just put that there, there is no reason to have instantiateParameters cause Transform itself is one of the parameters of instantiate

fiery steeple
#

Oh yeah, I took the first signature proposed here

its just them making a fancy struct for them so you don't have a big signature/method

i personally use var rather than explicit types for local variables. but it's really a personal preference thing. just figure out what you prefer and stick to that

fiery steeple

Ok 👍

rigid island
#

its easy if you can tell what type it is right away

#

var mything = new Vector3(1,2,3)
I already know var here is Vector3 cause its right there in assignment and so on

#

mhh

rigid island

sometimes without ide var is hard to tell what type it could be if you got a chain of stuff going on and bad variable names lol

Also check if you have a layout group on the parent

#

also are tiles actual Image component btw?

#

and if the layoutgroup recttransform is 100,100 as shown in picture thats why its putting them all in a single column

#

layout group is weird to use if you're doing a board of tiles with your custom code

#

But yeah why use the GLG if you want to position them in your code. Pick one or the other.

Or if you have a better way / the best way of doing things like that

hey there can anyone help me. I am trying to make flying enemies in unity and I do not know how to make them with the current graph agent system does anyone know how to?

rigid island
#

grid layout group is set to "flexible" so its based on its Width rect transform, so you'd need width = tilewidith + offset x grid width count size

pretty sure brackys or something made a tutorial on this

i did not know that let me check it out

I don't think Brackeys use the "agent system" as his videos are really old

personally I wouldve done this with spriterenderers not UI

normally you would not use navmesh for flying enemies for 3D

you would do something like an Octrees so you can properly a* it @fresh bay

SpriteRenders are most common used with 2D games cause it literally just displays 2D sprites.. The only difference these work how a stage play works in front of the camera

#

the benefit of UI is scales with the screen if chosen to do so, which may or may not be wanted..
spriterenderer stays same size relies on orthographic size for "zoom" of camera and viewport size how much camera can see

#

from what i hear Canvas is less performant when it has a lot of changing elements to draw

#

usually its not a problem if you correctly place them with good ortho size and good aspect ratio in game view to preview what it will look like.

#

anyway dealing with rect transform will be a slightly different also dealing with anchor positions

#

pick one and stick to it, the code itself doesn't change much

#

the grid layout group can be skipped

How do I remove the canvas being the parent of my tile in this prefab ?

rigid island
#

you can't the Tile is an Image and it needs a canvas to display

#

its not parent to it, its just being used temporarily to display the image
