#

if it works I wouldn't worry so much about a better way to do it.. as
i would be about understanding exactly what you have so far..
you can refactor more when you learn more

#

i guess this is useful for looping thru vectors? lol cool, TIL

For Vector2:

  • vector[0] → vector.x
  • vector[1] → vector.y

For Vector3:

  • vector[0] → vector.x
  • vector[1] → vector.y
  • vector[2] → vector.z

close enough 👍

#

now can you share the original question? or a link to it

solar torrent
#

🫷 olk I will

#

do you see like idk whats wrong it works until i does not

rocky canyon
#

its soemthing to do w/ the UnitySelectionManager and the units in that collection

#

can you share the UnitySelectionManager script?

private void TriggerSelectionIndicator(GameObject unit, bool isVisible)
{
    Debug.Log($"Unit: {unit.name}, Child Count: {unit.transform.childCount}");

    if (unit.transform.childCount > 0)
    {
        GameObject child = unit.transform.GetChild(0).gameObject;
        child.SetActive(isVisible);
    }
    else
    {
        Debug.LogWarning($"Unit {unit.name} has no children.");
    }
}```
#

i think you should probably check if thers a child first before manipulating..

#

from the video tho it appears all ur selectable units have a selection image.. (as a child) soo idk it seems like maybe its adding stuff that isnt?

#

id open the UnitSelectionManager component and keep an eye on that list and make sure its working how u expect

Unity web build has issue for looping sound. it make pop or void sound every loop

rocky canyon
#

https://www.youtube.com/watch?v=vAVi04mzeKk&ab_channel=SpawnCampGames

i have a tutorial on a top-down selection system.. maybe it might help to check my code and compare it to the one ur using.. (iirc i don't remember having that issue)..

i think the main difference I see is I don't add or remove units from the list from outside that class.. I tell the UnitSelectionManager which Unit it is.. and then it removes itself from the list..

solar torrent
rocky canyon
#

that way its not trying to remove it more than once.. or trying to access something that isnt there

rocky canyon

#

sometimes pops arent easy to notice.. could be just teh very last sliver of the audio file..

#

if u have some sort of audio editing tool you can shorten it or clip the end/beginning and see if the pop goes away.. or test w/ another clip

burnt vapor
# solar torrent

Ok but I asked for both the exception and the last log message

#

Remember I asked you to log the gameobject and the childcount until the exception is thrown

#

At this point it's just all assumptions until you start debugging

#

And now people like @rocky canyon will suggest the exact same thing because conversations have 40 minute intervals, after which we just start over again

#

So please pay attention and give us results if you want this to be fixed

public void Build()

    Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
    Vector3 targetPosition = ray.origin + ray.direction * range;

    Collider buildingCollider = currentBuilding.GetComponent<Collider>();

    {
        buildingCollider.isTrigger = true;
    }

    Renderer buildingRenderer = currentBuilding.GetComponent<Renderer>();
    Vector3 boxSize = buildingRenderer.bounds.size / 2;
    Vector3 boxCenter = targetPosition;
    Quaternion boxRotation = currentBuilding.transform.rotation;

    Collider[] hitColliders = Physics.OverlapBox(boxCenter, boxSize, boxRotation);
    bool canPlace = true;

    foreach (Collider hit in hitColliders)
    {
        if (hit.gameObject != currentBuilding)
        {
            canPlace = false;
            break;
        }
    }

    currentBuilding.transform.position = targetPosition;

    Renderer renderer = currentBuilding.GetComponent<Renderer>();
    if (canPlace)
    {
        renderer.material.color = Color.green;
    }
    else
    {
        renderer.material.color = Color.red;
    }

    if (isBuilding && canPlace && Input.GetMouseButtonDown(0))
    {
        isBuilding = false;
        currentBuilding = null;

        if (buildingCollider != null)
        {
            buildingCollider.isTrigger = false;

    }
    else if (!canPlace && Input.GetMouseButtonDown(0))
    {
        Debug.Log("Cannot place the building here!");
    }
}

So when the building is a floor it should snap to other floor. but not when the player is looking at a floor. How can I manage to do that?

pine jackal
#

Is there any option for it?

#

And this is my import setting

#

did you test blank project? different settings? different browser etc. You have to do more testing to isolate the problem. Also send a link of your webgl maybe its just your end

pine jackal

by the way which version of unity are u using?

ah before it

i want to share my issue video

here is my video

you can check it have something pop sound

or something void(empty) sound

this was not happen on ur?

okay but you should not be crossposting

hi, im making a top down rpg game similar to that of undertale. what is an efficient/effective way to manage/save/set a lot of bools to check if the player did some sort of action and change character dialogue according to the value of those bools? (i.e, a player chose to insult a character, next time they open the game the character is still bitter about them being insulted)

Sorry this is bit VS focused, but I can not see how to turn off the 'fade' effect when code is unused because its really annoying actually and I only remember the 3 dots effect. If i am in the middle of writing a class there may be unused functions - I do nto need the text to be faded!

you should probably use navmesh surfaces btw, this way of baking is deprecated

wait you're not even on Unity lts lol

dense root
#

Yes lol

rich adder
#

oh my

#

no wonder the bake tab didn't say deprecated

dense root
#

Hmm, I'll re-review the video I'm following and see if I missed a step. For future projects I'll use navmesh surfaces

rich adder
#

yeah they're much better because you dont have to painfully go through each gameobject to mark as navigation object and all that

dense root
#

Ahh makes sense, thank you for the guidance

if/when you come back with further questions on the navmesh .. use #💻┃unity-talk - it's not a code question

just put another gray image over it then scale it the direction you want, should be easy once you set pivot to top edge

#

Weird I'm getting the same error

rich adder
#

restart the editor?

dense root
#

I clicked reimport all and it restarted it, I can try again

rich adder
#

another reason you should probably be using lts

dense root
#

Yeah, I think I'll upgrade the project and spend some more time with it after a break. Thank you so much

rich adder
# errant pilot yes please

btw if you have a blank square you can set the image mode to filled and you can just use the slider so you dont have to worry about scaling anything or changing pivots

Haha I've done that couple times hit a button on side of my mouse when i go back to desk and puts a character into script ><

fading thunder

Hi! I'm following tutorials and using many other resources to mane a "first draft" while learning. Trying to make a 2d side scroller character jump, but it doesn't seem to want to do that no matter what I do...

Here's the code that I've got so far:

using UnityEngine;
using UnityEngine.Assertions.Must;

public class playerMovementNew : MonoBehaviour
{
    public float moveSpeed = 10f;
    public float jumpForce = 5f;

    public Rigidbody2D rb;
    public SpriteRenderer SpriteRenderer;
    public Vector2 movement;

    private void Start()
    {
        rb = GetComponent<Rigidbody2D>();
    }

    void Update()
    {
        movement.x = Input.GetAxisRaw("Horizontal");
        //movement.y = Input.GetAxisRaw("Vertical");

        if (Input.GetButtonDown("Jump"))
        {
            Debug.Log("Jump button pressed.");
            rb.AddForce(Vector2.up * jumpForce, ForceMode2D.Impulse);
        }
    }
    private void FixedUpdate()
    {
        rb.MovePosition(rb.position + movement * moveSpeed * Time.fixedDeltaTime);
        // ^Makes player actually move based on input. 
        if (Input.GetAxisRaw("Horizontal") < 0)
        {
            SpriteRenderer.flipX = true;
        }
        else if (Input.GetAxisRaw("Horizontal") > 0) {
            {
                SpriteRenderer.flipX = false;
            }
        }
        //^Makes the sprite flip directionally

    }
}

Any idea what's wrong here? I press space and the debug says I did, but the character doesn't go up.

naive pawn
#

did you set the jump force in the inspector to something else?

fading thunder
rich adder
#

ur overriding position with Rb.MovePosition

#

AddForce works on forces

naive pawn
#

(sidenote, comments that annotate code usually go before the relevant code, so you get an explanation before having to read the code)

fading thunder
naive pawn
#

you could replace MovePosition with setting the x velocity

# 
Vector2 vel = rb.velocity;
vel.x = /* intended x velocity (NOT proportional to deltaTime, since velocity is already per unit time) */;
rb.velocity = vel;
#

so the velocity would bemovement.x * moveSpeed

#

(if it's a sidescroller, not sure what you'd need a vertical axis control for)

fading thunder
naive pawn
#

i'd recommend you stick to a single, reputable guide, since different people have different styles and it's likely you'll encounter slightly different ways of doing stuff in different tutorials

naive pawn
#

try debugging some values. is movement being set? is isMoving being set?

formal hill
naive pawn
#

being assigned to correctly

formal hill
#

And how exactly would I check that with the debug.log?

naive pawn
#

you log the value out

#

and you see if the result is what you expect

#

just, Debug.Log(movement);, same for other variables

languid spire
#

And the reason your animations aren't playing is because you are starting them every frame

formal hill
languid spire
#

stop doing it

formal hill
formal hill
languid spire
#

it's not about not making them start, you are already doing that, it's about not doing it too often so apply some logic

maybe restrict calling AnimationStuff unless certain conditions are met?

made a script that has 4 drop zones and 1 general card to drop onto. Worked perfectly fine until I wanted to make the card bigger once dropped (changing the size to droppedSize). Problem is line 50 makes the card go back to the place where the card is picked from (startPosition). Chat gpt didn't really help

placid oxide
#

but it's the endragging event, should't it run only when I drop the card?

placid oxide
#

but it's the thing I want, to resize the card once dropped

rocky canyon
#

does that line cause any errors in the console or is this just a
"working, but not desired outcome" type of problem?

placid oxide
#

not even working, it doesn't even resize the card, it just make it go back to the default position

rocky canyon
#

that might be the root cause of ur issue

# 
if (currentDropZone != null)
{   //grab components
    RectTransform rectTransform = GetComponent<RectTransform>();
    RectTransform dropZoneRect = currentDropZone.GetComponent<RectTransform>();

    // set position to match dropzone position
    rectTransform.anchoredPosition = dropZoneRect.anchoredPosition;

    //optional assignments
    rectTransform.anchorMin = new Vector2(0.5f, 0.5f);
    rectTransform.anchorMax = new Vector2(0.5f, 0.5f);
    rectTransform.pivot = new Vector2(0.5f, 0.5f);

    // set size
    rectTransform.sizeDelta = droppedSize;
}```
#

screen space coordinate system vs world space coordinate system

#

that said and all.. But chosing to use UI for a 2D type of game probably isn't your best choice.. (not sure how much you've already built)
but Unity UI usually isn't the most performant.. and is meant to be used more so to display stuff(info) to you..

as for interacting w/ the objects I'd probably chose to use 2D Sprites.. those will exist in world-space and will be much easier to drag, drop, and interact with..

#

even if they're "text heavy" you could pair 2d sprites w/ textmeshpro world text objects

#

either way.. the .rectTransform.anchoredPosition is the bit that will fix what you already have..

#

if u go w/ 2d sprites instead you can resort back to the basic transform.position = thatPosition; type positioning

placid oxide
#

it doesnt )))

#

now it doesnt stick at all

rocky canyon
# placid oxide it doesnt )))

it does work.. maybe not w/ your setup for some reason

    public void TopLeft()
    {
        thisRect.anchoredPosition = topLeft.anchoredPosition;
    }``` etc, same for each of the test methods i call in the clip
for yours, not sure, I'd probably suggest:
make sure your components are assigned.. (like the recttransform you grab w/ your getcomponent methods)
can debug them afterwards to see that they're assigned ` Debug.Log(rectTransform.name);`
make sure you're setting its `anchoredPosition` debug it afterwards see if it has a value that makes sense `Debug.Log(rectTransform.anchoredPosition);`

put some debugs in  ur if statements make sure they're being called like you expect
`Debug.Log("If statement is true, doing this"):`, same w/ else, or false, or w/e
nothing more comes to mind besides something i'm just not seeing.. or some error you haven't revealed yet
#

the logs and stuff should tell you whether its an issue w/ ur logic flow
or its a problem w/ assigning the wrong values or variables

I used a tutorial for the base of the game

I know but i dont want to take the just redo the game in another style way yet since not much is left to do

rich adder
#

another style?

placid oxide
#

Not using only canvas

rich adder
#

if you plan on using colliders/physics then you'd switch it to using sprites,
if you use canvas then you have to use the event system instead with all the functions that come with

#

the canvas and the physics objects are not even in the same space

Hi, i been thinking, how i can make the sprite of the character of a 2D game flip depending on where the mouse is?

obtuse quarry
#

my pathfinder gets stuck here

27DBD956-0577-48E2-9C18-0A7C0A42F4F1.png
#

tho it can pathfind around other structures of blocked cells

acoustic belfry
obtuse quarry
#

there are some cases where it cant pathfind around certain cells

#

it perfectly pathfinds around this structure of blocked cells

DECC9D30-27CB-47E4-9AEA-09943AAFE77B.png
#

its an image so you cant actually see it get to the destination, but it does

#

and it gets to the destination no matter where it starts with this structure and many others

#

there are just edge cases where it cannot

#

i know the code is definitely terrible, this is just a prototype keep that in mind

rocky canyon
stable quail
rocky canyon
#

theres usually two options..
"scale the object negatively (this works out well most times b/c the axis will flip w/ it"
or you can flip the sprite FlipX (this means you need two states of movement.. when lookin left, if lookin right

acoustic belfry
rocky canyon
acoustic belfry
#

I use it for flip it

#

Bad idea?

rocky canyon
#

nah, its a completely acceptable option..

obtuse quarry
#

are you trying to detect which side of the player the mouse is or something?

acoustic belfry
#

Yep

rocky canyon
#

but note that the axis will not flip around.. (ur transform.right) (y axis in 2d) will always point right..

#

if u scale the object negatively.. then the axis will flip so looking right will have the axis pointing right.
and looking left will have it left

obtuse quarry
#

if its just for the appearance flipping the sprite should be fine

rocky canyon
acoustic belfry
#

How?

obtuse quarry
#

i must suck at programming

acoustic belfry
#

Me too

#

;-;

rocky canyon
#

positive value would be on the right side.. and negative value would mean its on the left

obtuse quarry
#

i know what it does ive jst never used it in this application

rocky canyon
polar acorn
# acoustic belfry How?

Dot Product can be thought of as a "Sameness" value of two direction vectors. If it's 1, then both vectors are pointing in the same direction. -1 is opposite, 0 is perpendicular.

acoustic belfry
#

Ok. But i mean, now i can detect the left and side of the mouse...but how i can detect the mouse itself?

obtuse quarry
#

like its position?

acoustic belfry
#

Yep

rocky canyon
obtuse quarry
#

Camera.ScreenToWorldPoint(Input.mousePosition) i think

#

or something like that

#

to get its world pos

polar acorn
acoustic belfry
#

So how the script would look like?

acoustic belfry
#

Ok

obtuse quarry
#

itd be like this i think

Vector3 mousePos = Camera.main.ScreenToWorldPoint(Input.mousePosition);
mousePos.z = 0;

to get the world position of the mouse

polar acorn
#

Although if it's 2D, ScreenToWorldPoint should be fine

#

You only really need to worry about the ray for a perspective camera

#

If you just need left/right and don't care about any other directions, you can just check if that result is less than or greater than the player's X position

obtuse quarry
#

yeh

(URP) I'm trying to add a flashing to my game, but it doesn't go nearly far enough to see what's in front of you. Turning up the intensity of the flashlight makes it still not go far enough, and flash the player when looking at something too close. I can't seem to find a way to make the flashlight see further and also be darker up close. Is there a fix to this? (first image intensity 3, second image intensity 30)

I'm trying to go for a flashlight that is far reaching, but not super bright up close. I want to be able to see where I am going in my map, but currently the light is too bright for that. My game is a speed parkour game and running into walls is pretty annoying. I originally had the whole map have a light cast on it so you could see, but it looked terrible. I'm making a flashlight mostly for ambience. End goal is just to tone down the light up close.

for enemy ai, would a breadcrumb solution suffice? like the player drops a "breadcrumb" every certain interval and if the enemy has los of a breadcrumb it moves towards that breadcrumb

steep rose
#

sure if you want it to follow the last players position, I would just use the conventional A* for AI enemies though

obtuse quarry
#

i thought a breadcrumb solution would be good because

i dont want the enemy to always know where the player is after seeing it, with breadcrumbs if the enemy loses los of the player it can just move to whatever breadcrumb is in los and if it can see the player when it gets to that breadcrumb then great else it can be idle

#

ive tried A*

#

its nice but not what i need

slender nymph
#

a* and this breadcrumb idea are not mutually exclusive. I do this in one of my projects and use navmesh (which uses a*) to move the enemy

obtuse quarry
#

does navmesh work in 2d?

steep rose
#

no

#

A* can be used in 2D though as it is only an algorithm

obtuse quarry
#

oh

slender nymph
obtuse quarry
#

ill check these options out

#

ill go through them and see which one is good for me

#

A* probably will be better, in the past it just didnt really work out

steep rose

A* is probably the best pathfinding algorithm unless you need hundreds of objects pathfinding to a certain position, if that's the case use flow fields

Could I get some help regarding raycasts in 2D please?

I am having trouble getting the raycast to detect my player and return a RaycastHit2D. I have given the required parameters as seen below.

RaycastHit2D los = Physics2D.Raycast(m_mob.transform.position, (collider.transform.position - m_mob.transform.position).normalized, m_visionRadius, m_targetLayers);
Debug.DrawRay(m_mob.transform.position, (collider.transform.position - m_mob.transform.position).normalized, Color.red, 0.1f);

I also drew rays to make sure it is actually looking at all colliders within the specified radius that belong to the Player layer as seen here

Collider2D[] targetColliders = Physics2D.OverlapCircleAll(m_mob.transform.position, m_visionRadius, m_targetLayers);

So far the colliders and debug rays are correct, they point at every collider belonging to the Player layer, however, the raycast isnt working as expected.

I have provided it the correct vector values since the debug ray works fine and takes in the same values, however it doesn't seem to return anything from the method, its always null.

It uses the same values as my OverlapCircleAll arguments but it doesn't return anything despite being in direct line of sight.

  • I have read the docs many times over and I don't know what I'm doing wrong.
  • Also, how do I specify a layer with colliders the block line of sight in addition to the layer I wish to detect the collider using the raycast from?

obtuse quarry
#

in pathfinding should i use manhattan distance or regular Vector3.Distance?

steep rose
#

Manhattan (as it works for grids) if you are using A*

obtuse quarry
#

i searched it up and apparently manhattan distance isnt good for diagonal movement

#

and stuff

steep rose
#

huh?

#

why would it be bad for diagonal movement

#

it just makes the distance between the current node and the top/down , right/left/down/up movments a distance of 2

obtuse quarry
#

oh

#

okay ill try it

steep rose
#

now if you want the distance to be 1.4 for diagonal movement just use the √2

#

which is somewhere around 1.4

obtuse quarry
#

would that benefit?

steep rose
#

I've never tried it

#

but I'm guessing it will be roughly the same, you can google the differences if you would like

obtuse quarry
#

i cant get past this

4420A875-3253-4F25-BCF4-F600E4D63E8C.png
#

and obstacles placed like it

#

but most other setups work fine

steep rose
#

are all of the Fcosts correct? are you checking all of the neighbors around the current node?

obtuse quarry
#

yea, im moving to the neighbor whos fcost is the least

#

fcost = gcost + hcost

steep rose
#

are you ignoring the current node?

obtuse quarry
#

yeah, you cant see it because its an image but the pathfinder just continuously moves between 2 nodes

steep rose
#

so it does pathfind?

obtuse quarry
#

to something

#

just not to the right place

#

and it works fine with no obstacles and when obstacles are placed in certain ways

#

i can see which cells have the lowest fcost, the cell i have selected apparently has the least fcost

60290DAC-1589-40D8-A7E0-7756AA9309EA.png
#

and now this cell i have selected has the lowest fcost

40916045-2903-4090-862B-4C2304BB32EE.png
#

and the pathfinder continuously moves between these cells

steep rose
#

are you checking end to start or start to end

obtuse quarry
#

what?

steep rose
#

the current node on start of the project should be the starting node I believe

obtuse quarry
#

yep

steep rose
#

then you pathfind to the end node, then retrace steps (to get the path)

obtuse quarry
#

oh im not doing it that way

#

even ill admit i have no idea what im doing imo

#

what ive done has gotten me this far

somber beacon
obtuse quarry
#

basically i just move to whichever neighboring cell has the least fcost

somber beacon
#

and on every step you will change the grid position you are in as an obstacle, and when that agent gets out of it, you make it available again

steep rose
#

I'm guessing you are which is good

obtuse quarry
#

yeah, the list of neighboring cells i get doesnt include obstacle cells

steep rose
#

Sebastian league has some good stuff on A* pathfinding, some good information that you can use

obtuse quarry
#

it only includes valid cells

obtuse quarry
#

i watched his introduction video

#

in theory i think the way im doing it should be working

#

idk why it isnt

If we're talking like 2D zelda boomerang you're just moving a transform and giving it some collider

creating a mechanic or system is all about logic (coding in general). once you know/understand the logic, you substitute the logic with its programming counterpart . . .

If you want curving, you can create a path using AnimationCurve but I'm pretty sure Zelda was just a straight forward throw and return

#

3D versions had more realism to them

if it's like a terraria boomerang make sure it's going towards the player instead of the starting position after the apex

you could also use acceleration instead of a distance check

hello unity heads, im having some trouble with a coroutine

#

I am making an arcade racer. At the start of the race, I use an Ienumerator to countdown to the race start, this works fine. I want the player to be able to quickly restart the race, so I would like to run the coroutine again, however the countdown somehow end up as a negative number?

hexed terrace
#

because you haven't reset the number at the start of the countdown

hazy crypt
#

I have done this

hexed terrace
#

not properly, otherwise it wouldn't go negative

hazy crypt
# 
    {
        //reset collectibles
        currentCollectibles = 0;
        UpdateCollectibleCount();
        hasAllCollectibles = false;

        // set vars so that the player can reset with R key after finishing
        raceStart = false;
        raceEnd = false;

        // turn off end screen
        EndRaceBackground.SetActive(false);
        LeaderboardBackground.SetActive(false);
        NavigationBackground.SetActive(false);

        //reset race timer and countdown to start 
        timerTime = 0;
        countinTimer = 3;

        StartCoroutine(CountdownToStart());
    }
#

This is the reset race method

#

the countdown definitely does go back up to 3, but it counts down twice as fast

hexed terrace
#

ok.. show the rest..

frail hawk
#

how about stoping the first coroutine

hazy crypt
#

If I keep resetting it, it always back to 3 straight away and then instantly jumps to a negative number

# 
    IEnumerator CountdownToStart()
    {
        while (countinTimer > 0)
        {
            countinTimerStarted = true;
            yield return new WaitForSeconds(1f);

            countinTimer--;
        }
        countinTimerStarted = false;
    }
hazy crypt
frail hawk
#

well if you restart you would have to stop the current coroutine

hazy crypt
#

I see

#

It doesnt stop running on its own>

#

How would I do that

hexed terrace
#

you shouldn't need a stopcoroutine, you should be exiting it properly when the countdown finishes

languid spire
#

should you not be setting countinTimerStarted = true; somewhere?

hazy crypt
#

That was my assumption but im learly wrong somewhere

hazy crypt
#

its there

languid spire
#

no it's not

naive pawn
hazy crypt
#

line 6

hexed terrace
#

that bool doesn't look like it does anything anyway - probably used elsewhere

naive pawn
#

(it should probably be before the loop?)

hazy crypt
languid spire
#

if you are expecting your coroutine to do something, should it not call something after the while loop has finished

hazy crypt
#

Im only using it to display the countdown on screen

naive pawn
#

and not to control the actual start?

hazy crypt
#

I display "countInTime" at the race start

hazy crypt
naive pawn
#

so how are you controlling the actual start

hazy crypt
#

Im not sure what you mean

#

oh right

# 
        if (countinTimer > 0)
        {
            raceStart = false;
            countdownText.gameObject.SetActive(true);
            countdownText.text = countinTimer.ToString();
            countdownBackground.SetActive(true);
        }
        else
        {
            raceStart = true;
            countdownText.gameObject.SetActive(false);
            countdownBackground.SetActive(false);
        }
naive pawn
#

how are you controlling them not to start before the countdown is over

hazy crypt
#

This is in the update method

hazy crypt
naive pawn
hazy crypt
#

Yeah its inefficient

#

But its not the cause of my current problem

#

I can make it pretty later

naive pawn
#

(it's probably not related to the current issue, but that may cause issues with having like, a proper, understandable logic flow in the future)

hazy crypt
#

Yeah thank you, ill take that on board

languid spire
#

this
yield return new WaitForSeconds(1f);
should probably be WaitForSecondsRealtime

hazy crypt
naive pawn
#

WaitForSeconds is scaled according to Time.timeScale

languid spire
#

because WaitForSeconds is frame rate dependent

hazy crypt
#

I have changed it and the problem still occurs

naive pawn
#

have you tried debugging the coroutine? seems like it should exit on its own just fine

hazy crypt
#

Im not sure how I would go about this

rich adder
#

debug.log

naive pawn
#

just, Debug.Log in the loop, Debug.Log after the loop

hazy crypt
#

Okay, sounds good

#

I have been printing the countInTimer to the console

#

looks like this on the right

naive pawn
#

in what, Update?

#

is countinTimer being set anywhere else?

rich adder
#

check also how many coroutines you running

#

if(countinTimerStarted) return; StartCoroutine(CountdownToStart());

hazy crypt
#

So it looks like when i start the coroutine on reset, it never stops

#

the first instane does

#

instance

naive pawn
#

how are you calling Restart?

hazy crypt
#

pressing the "r" key on my keyboard, and also from the end screen and options menu

#

i have an event manager handling it

yes

        {
            EventManager.RestartCurrentScene();
        }
#

In the gamemmode controller

naive pawn
#

in Update?

hazy crypt
#

yeah

devout flume
naive pawn
#

yeah you're starting a coroutine every frame that R is held down

hazy crypt
#

shit

naive pawn
#

so the coroutines are being stopped

#

there's just more than 1

hazy crypt
#

that figures

rich adder
#

called it 😅

hazy crypt
#

thanks guys

naive pawn
#

and the decrement happens before the check, so they're all decrementing

hazy crypt
#

Ill go fix this

#

If it breaks again, which it will, ill be bak

naive pawn
#

use it as a button/key instead of an axis and check for the frame it's pressed

rich adder
#

also you have a bool. use it. Never hurts to assure yourself

#

if(countinTimerStarted) return; StartCoroutine(CountdownToStart());

naive pawn
#

also edge case to test while you're at it: what happens if you press R while the countdown is active?

I see ok so I have a 2d game where when you hit the zombie he dies but the problem I am having is or the game object dies so I made him go invisible but I can figure out how to make it go back to visible

why do you need to make it visible again

are you trying to achieve object pooling or something

The game I'm working on is zombie survival the problem I have is that I have a zombie spawner when I kill the zombie the game object that is the zombie destroyed it self so to fix that I made it go invisible but when new zombies appears it is invisible

yeah that should happen if you aren't pooling them. why is that an issue?

It looks like you've independently come up with the concept of object pooling. You've got the basic concept right, but might be a bit confused on the implementation. Here's a tutorial on the concept:

my problem is player vertical camera jitter lag when falling. I fixed it by turning interpolate to none on my rigidbody but then it made my game feel horrible and the bullets are super laggy now. Is there anything else I can do to fix the jitter lag when falling without turning off interpolate ?
I can send my player movement or camera script

did you use a cinemachine

#

you can get it from package manager

faint agate

cinemachine is a gameobject

#

you can make it follow a gameobject you assign in the inspector

#

I dont know why but I thought about 2d

#

what does your camera script do?

faint agate
#

https://pastecode.io/s/3ha6snzi

so here is my camera script.
first, I'm setting the direction in which the player is start facing, then I check if game is playing, if so then I can control the player looking around. Next is setting the sensitivity and camera rotation logic along with if im on a wallrun which is probably where my issue is somewhere

#
  • on the y axis, if I move too fast sliding to rocket jumping. Its like the camera starts kicking back trying to get itself back in place
sharp abyss
#

is camera child of your character

faint agate
faint agate
sharp abyss
#

do you set cameras position in MoveCamera script?

#

maybeusing fixedupdate can solve or making camera child of the player and not setting it by script

faint agate
#

Heres the moveCamera script. In this script I tried making it fixed update, but then the camera become super unsmooth

#

i think i found the problemmm

sharp abyss
#

what is it

hazy crypt
#

guys why does my new input manager package thing not look like the tutorials? I cant assign any global actions or anything

faint agate
# sharp abyss what is it

On my main camera, theres a script to handle player clipping. When I turned it off the bug went away but now I can look through wall if im next to one and look all the way down. fixed one issue to have another lol

naive pawn
faint agate
fading thunder
#

Okay this is puzzling for me. I'm working on my first 2d sidescroller as a learning project, and I am just this simple script for the camera to follow the player:

    public GameObject playerDefault;

    // Update is called once per frame
    void LateUpdate()
    {
        transform.position = playerDefault.transform.position;
    }
}```

But when I actually playtest, the camera does position itself at the player, but it doesn't show anything except the empty background...
#

any idea what could cause that?

hazy crypt
fading thunder
#

Oh, so even though it's 2D, I need to offset ?

faint agate
#

just in case
https://pastecode.io/s/wtjmpi48
heres the script that messed up my camera. When this script was active, the camera starts kicking back trying to get itself back in place if moving too fast. I turned it off and everything is fine now

hazy crypt
#

youre not just looking at the thing, youre inside of it

#

you need to zoom out away from it

naive pawn
fading thunder
#

Ahhhh yeah that makes sense now. Ty.

naive pawn
#

the z index in 2d is depth

#

you may notice the camera is at z=-10 by default

you don't have to share the entire thing, just the line where you're declaring playerNameInput

past spindle
#

[SerializeField] Text PlayerNameInput;

#

So just switch that to [SerializeField] TextMeshProUGUI PlayerNameInput; ?

runic lance
#

yeah, that looks correct

#

Text is the old unity text component, you should avoid it

past spindle
#

What about the later reference to PlayerNameInput.text; ? Do I need to adjust for this change or can that stay the same?

naive pawn
#

does it error?

#

if not, no

past spindle
#

lol fair enough

naive pawn
#

that's just how you'd do it in general lol
if it does error, you'd have to check docs for what the right property is
you should check regardless to make sure it's not subtly different, but i mean, this is pretty straightforward lol

past spindle
#

That does seem to fix the problem. I would like to check the property though, as you said. I would just google TextMeshProUGUI, yeah?

naive pawn

yeah

past spindle

cool thank you

some extra keywords like "unity" or "tmp" would help ensure you get the right docs

and you could also just go to tmp docs and search the class there

no, the player which is the one being knocked back

moveInput = Input.GetAxis("Horizontal");
rb.linearVelocity = new Vector2(moveInput * moveSpeed, rb.linearVelocity.y);

if (moveInput != 0)
    transform.localScale = new Vector3(Mathf.Sign(moveInput), 1, 1);
slender nymph
#

rb.linearVelocity = new Vector2(moveInput * moveSpeed, rb.linearVelocity.y);

#

what a surprise, you over write the velocity

abstract copper
#

is it not only when moving the key

slender nymph
#

unless there's some logic preventing this code from running when no key is pressed or for the duration of the knockback, then no

#

of course if you do have logic that prevents this from running when you do not press one of the Horizontal axis's keys, then you never stop either

#

don't mix assigning directly to velocity with AddForce unless you know what you are doing. use one or the other. otherwise you need to prevent input from the player (and this code you've just shown from running) for the duration of your knockback so you don't just immediately assign the velocity again

Hey guys, I was thinking maybe I should just [SerializeField] all component references or object references because it's faster than doing

void Awake()
{
  rb = GetComponent<Rigidbody2D>()
}

or

void Awake()
{
  boss = FindObjectOfType<BossMovement>().transform;
}

Would that be good practice?

slender nymph
#

a serialized field is definitely faster than using any of the Find methods

fading mountain
slender nymph
#

it is perfectly fine to do so and is preferable over using any of the Find methods because those are all incredibly slow

How to rotate an object toward another 2D

timber tide
#

atan2

bronze carbon
#

how should i be connecting my player to the ui? ive tried using events to notify the ui when values change, and it mostly works, but im left with placeholder values until the values change for the first time because i cant guarantee that the ui is ready to listen when the player object starts itself
my only other idea is to give the ui a reference to the player and read the values every frame but that seems wasteful

timber tide
#

Events are usually the idea, but just communicating to the UI every time your health decreases or something similar is pretty standard

queen adder

There's many ways you can rotate in 2D in unity, even using quaternions

steep rose
#

quaternions are evil

timber tide
#

People give Unity a lot of crap for not having traditional 2D, but having the ability to use those methods makes up for it

steep rose
#

but necessary

fading mountain
rocky canyon
# 
// Set rotation using Euler angles
transform.rotation = Quaternion.Euler(0, 0, angle);

// Smoothly rotate to target
transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, Time.deltaTime * 10f);

// Rotate around target's position
transform.RotateAround(target.transform.position, Vector3.up, rotationSpeed * Time.deltaTime);

// Align object's up direction with a vector
transform.up = direction.normalized;

// Rotate to face the target
transform.LookAt(Target);

// Rotate around Y axis
transform.Rotate(0f, rotationSpeed * Time.deltaTime, 0f);
#

soo many ways to rotate stuff
i still dont know which one my favorite..
I tend to use rotation = Quaternion.AngleAxis the most i guess

bronze carbon
obtuse quarry
#

I usually use the atan2 for rotating towards another object

#

Quaternions just don’t work for 2d ig

rocky canyon
#

atan 2 is normally the next step after getting a direction

obtuse quarry
#

Yeh

rocky canyon
#

lot of those methods require a bit of math before hand

#

then u got magic ones like LookAt()

#

which im pretty sure also uses Atan2

# 
Vector3 direction = target.position - transform.position;
float angle = Mathf.Atan2(direction.y, direction.x) * Mathf.Rad2Deg;
transform.rotation = Quaternion.Euler(0, 0, angle);```
#

my golden rotation code

naive pawn
rocky canyon
#

one liners eh

naive pawn
#

i was already on that one line and didn't feel like making more stuff lol

rocky canyon
#

that makes me wonder if theres any optimizations to be had to write a little extension method to pass in two directions and just get the angle needed w/ the atan2 and the conversion

obtuse quarry
eternal needle
obtuse quarry
#

It’s about the same through other game engines that don’t already have a function for it

rocky canyon
bronze carbon
rocky canyon
# 
   public override void _Process(float delta)
    {
        Vector2 direction = target.Position - Position;
        float angle = direction.Angle();
        Rotation = angle;
    }``` seems Gadot *does* have that extension method 😉

agile oracle
# wintry quarry > combat with weapons This is really just too vague. The answer is, it depends.

so in my game, i plan on implementing multiple melee weapons (and maybe ones that shoot projectiles). the player and enemies can both perform combat actions like swinging the weapon. right now, i handle combat with a script on the player/enemy game objects. the player executes the attack by pressing the left mouse button, and the enemy does if the player is in the “attack space” (some area that triggers the enemy to chase the player).

when the player or enemy swings their sword, and the sword’s collider detects a collision, it raises an event that the target’s health component listens for, and then promptly decreases the health.

this is fine for now, but there’s an issue with this. since the enemy follows the player, there’s a chance it will hit the player’s sword even when the player is not swinging, which causes the enemy to lose health, and the enemy should only be damaged by the sword if the player is swinging.

i’m sorry if this is too long winded btw

wintry quarry
#

It's better to use direct physics queries

bronze carbon
# bronze carbon how should i be connecting my player to the ui? ive tried using events to notify...

i have:

  2. a Player script that fires a HealthChanged event when it gets hurt
  3. a PlayerUI script that adds a callback to the HealthChanged event in its Start() method
    i want the player ui to update with the players health as soon as the player spawns, but the player could spawn before the ui does and i cant find a way to handle that
