Whenever I start dragging something with this code, it seems to call the coroutine twice, am I missing something obvious?


        private void Update() {
            // Make sure the user pressed the mouse down
            if (!Input.GetMouseButtonDown(0)) {
                return;
            }

            var mainCamera = FindCamera();

            // We need to actually hit an object
            RaycastHit hit;
            if (!Physics.Raycast(mainCamera.ScreenPointToRay(Input.mousePosition).origin,
                    mainCamera.ScreenPointToRay(Input.mousePosition).direction, 
                    out hit, 
                    100,
                    LayerUtility.GetLayerMask(Layer.UPGRADE)
                    )) {
                return;
            }

            // We need to hit a rigidbody that is not kinematic
            if (!hit.rigidbody || hit.rigidbody.isKinematic) {
                return;
            }

            if (!m_SpringJoint) {
                var go = new GameObject("Rigidbody dragger");
                Rigidbody body = go.AddComponent<Rigidbody>();
                m_SpringJoint = go.AddComponent<SpringJoint>();
                body.isKinematic = true;
            }

            m_SpringJoint.transform.position = hit.point;
            m_SpringJoint.anchor = Vector3.zero;

            m_SpringJoint.spring = k_Spring;
            m_SpringJoint.damper = k_Damper;
            m_SpringJoint.maxDistance = k_Distance;
            m_SpringJoint.connectedBody = hit.rigidbody;
            
            StartCoroutine(nameof(DragObject), hit.distance);
        }

how can you tell it's calling it twice?

elfin tree
#

from logs... but now it got weirder

#

I tried reverting to the old code

#

but my Debug.Logs that are in the other script are still being called

#

created another script to make sure and same thing, in inspector i can see it's the right one there

#

ima restart pc at this point something's off

#

ok i'm just dumb i think ifigured it out

clever bridge
#

Hello all, I have a code where I have a sprite with paint on it and I want this code to fade the paint away, I'm not getting any errors but it's actually making the alpha less faded and I don't know why

somber nacelle
#

that is one of the worst sites you could have chosen to share code with. there's no syntax highlighting and it is replacing characters with the html names

#

but what is the value of fadeAmount

clever bridge
#

50

#

what is an alternative site

somber nacelle
#

any of the sites that the bot recommends for posting !code

tawny elkBOT
clever bridge
#

when i debug the value of the alpha it always says 255

somber nacelle
clever bridge
#

when I debug it it says 255

knotty sun
clever bridge
#

then why does it say it's 255

knotty sun
#

no idea Color32 is probably what you should be using

somber nacelle
#

is currentColors perhaps an array of Color32?

clever bridge
#

and when I made fade amount 0.01f it still says 255 and doesn't work

#

yes it is

#

Color32[]

#

I'll put the whole thing in a proper paste site

somber nacelle
#

that's why. but colorChange is Color not Color32 so that uses values from 0 to 1

clever bridge
#

ah

#

so I should say new Color32?

somber nacelle
#

well that likely won't fix the issue

knotty sun
#

is that not what we already said?

somber nacelle
#

but at least that would make your math more correct

clever bridge
#

I put the code in a different page and added the relevant variables

#

when I change it to 32 it errors the alpha subtraction saying 'cannot convert float to byte'

#

I just realized Color at the beginning also needs to be Color32

#

doesn't change the error though

somber nacelle
#

yes well you cannot subtract a float from a byte and expect to result in a byte

knotty sun
#

not quite sure why you don't just do

Color32 colorChange = currentColors[array_pos];
colorChange.a -= (byte)fadeAmount;
clever bridge
#

so that works now, thanks! It still lags whenever it runs the code, because it's checking all 10000 pixels of multiple sprites, not sure how to make it more cpu efficient, I may drop the fading altogether

#

I have multiple 100 x 100 pixel sprites that I paint on, I wanted the whole game to be paintable, and I wanted rain to wash the paint off, hence the fading code, but it lags the game when it does the fade, so i may not use it at all

knotty sun
clever bridge
#

also, the problem now, is the alpha cycles now, it fades, then when it becomes less than 0, it goes back to 255

#

My code says if it fades enough, to make it zero, but i'm guessing it's never 0 because it cycles back and that else statement never happens

knotty sun
#

well 255 divided by 50 will never give you 0

clever bridge
#

right

knotty sun
#

51 will

clever bridge
#

I assumed it worked like a float where if it goes less than 0 it will make it 0

#

nice

knotty sun
#

never assume

fervent furnace
#

underflow
btw i dont know why you check the coordinate but you bound the loop at the same time

clever bridge
#

I'm not sure what you mean

thick terrace
clever bridge
#

so I could just GetPixels32() in Start and it would be the same?

#

that makes sense

#

I've already stored it in the array

#

and when I want to change it I can just SetPixels32() when I want to apply the changes

#

currentColors is already what I want it to be

thick terrace
#

doing it that way would save the cost of copying every pixel back into the texture too

fervent furnace
# 
for (int x = 0; x <= 99; ++x){
  for (int y = 0; y <= 99; ++y){
    // Need to transform x and y coordinates to flat coordinates of array
    int array_pos = y * (int)paintableSprite.rect.width + x;
    // Check if this is a valid position
    if (array_pos >= currentColors.Length || array_pos < 0)
      return;
thick terrace
clever bridge
#

I just updated the paste

fervent furnace
#

actually the code will wrong if paintableSprite.rect.width is not 100

clever bridge
#

every blank sprite I use is 100 wide

fervent furnace
#

the range of x mismatch

clever bridge
#

I just changed the paste, it should be good now other than the return; I had, now that it's a coroutine what should I change that to

#

continue?

#

and I'm not sure how to do a row every frame like SteveSmith said

#

I think I did it right

fervent furnace
#

is the width of every sprite you use are the same?

clever bridge
#

yes

#

every blank sprite I'm using this for are all the same dimensions

#

I have a folder of them in the assets folder they are painted on during the game and cleared when the game ends

#

64 blank 100 x 100 pixel sprites

thick terrace
clever bridge
fervent furnace
#

you have bound the loop and you dont need to check index out of bound actually, if you are really afraid of that then use debug.assert to verify if the dimension is correct

thick terrace
clever bridge
fervent furnace
#

yes

clever bridge
#

I changed it to this

                        yield break;```
#

If alpha is already 0 I don't want it to check it

fervent furnace
#

yield break is to stop the iterator

thick terrace
#

if you just want to skip that pixel you want continue , yield break exits the whole method

clever bridge
#

ok

#

so the place I have yield return null is making it wipe sideways

#

I need to put the x loop inside the y loop don't I

#

which is what simonp said

#

ok it does rows now, but I need to iterate it backwards

fervent furnace
# 
for(int fast=0;fast<arr.length;){
  int bound=fast+column_length;
  for(int slow=fast;slow<bound;++slow){
    //access the element in flatten 1d array directly by arr[slow] to save one addition and multiplcation, assumn the array is picked as [columns in row0,columns in row1,...];
  }//here you finished one row
  fast=bound;
}
```a slightly faster way to loop, though i think you wont see any differences in terms of execution speed unless your image is really a long 1d array
clever bridge
#

to make it wipe from top to bottom

#

GetPixels32() does turn the pixels into one long 1d array

hey guys i ran into an issue, if i change my color through this script to black on runtime, it changes the color forever, even when you press stop the material color doesn't get reverted back. Does someone see the issue here?

aight thx guys ill look into those things

Or access the materials from the renderers using .material this will create a copy

Does anybody know where A* puts its movement code? I'm trying to take the x,y,speed values to make my blend tree play the correct animations and rigid body values don't work, but when i use delta position, it also doesn't work

probably the package

doube click the file and open it?

static matrix
#

how could I make a shader where the visible pixels follow a sinwave?

# 
if(sin(unity_DeltaTime.w) != sin(i.uv.y)){
                col.a = 0;
               }

heres my latest attempt

leaden ice
#

what do you mean by the pixels following a sine wave?

cosmic rain
leaden ice
#

That could mean like 10 different things in my mind

static matrix
#

effectively
square
but the only visible pixels are the ones on a sinwave

leaden ice
#

Still vague

#

like you want an oscilloscope?

cosmic rain
#

Maybe draw a picure of what you want it to look like

static matrix
#

although it could be non-moving too

leaden ice
#

so you want an oscilloscope

static matrix
#

probably

leaden ice
#

you want to only draw a pixel if it lies on the graph of Sin(x)

static matrix
#

this is 2d, just to clarify

spring creek
leaden ice
#

so i'd do something like:

float expectedY = sin(uv.x);
float distanceFromExpected = abs(uv.y, expectedY);
float alpha = step(distance, something, threshold);```
#

i don't remember how the step function works

static matrix
#

interesting

#

I was about to ask what step does heh

leaden ice
#

but basically this will say cut out the alpha for any pixel that's too far from the graoh

#

that step part definitely needs modification

#

one sec

#

ok so actually:

float expectedY = sin(uv.x);
float distanceFromExpected = abs(uv.y, expectedY); // how far are we from the true sine wave?
float alpha = step(lineThickness, distanceFromExpected);
col.a = alpha;```
static matrix
#

should the thinkness be on scale of 0-1 or full ints?

leaden ice
#

it's distance in UV units

#

0-1

#

try this and see what you get I'm curious 😆

#

it makes sense in my head but obviously untested

#

this is also assuming alpha is 0-1 as well

static matrix
leaden ice
#

oh sorry

static matrix
#

should it be the abs of the distance?
or subtracted?

#

just subtracted I presume

leaden ice
#

abs(uv.y - expectedY);

#

this is what I meant yeah

static matrix
#

its.... close

image.png
#

I'd need to change the frequency and also I think invert it

leaden ice
#

Uhhh now that I think of it we might actually want:

float expectedY = (sin(uv.x) + 1) / 2;```
#

because sine gives us [-1, 1]

#

and we want [0-1] because UVs are 0-1

static matrix
#

makes sense

leaden ice
#

and yeah if you want to change the frequency you'd do sin(uv.x * freq)

#

so:
float expectedY = (sin(uv.x * freq) + 1) / 2;

static matrix
#

very very close
this is pretty cool in its own right
shaders are awesome
but i'd need to invert it so the transparent parts are red and the red parts are transparent

image.png
leaden ice
#

nice!

#

yeah try reversing the parameters in the step function

#

or getting rid of the 1 - part if you still have that

#

but yeah that looks great actually haha

static matrix
#

huzzah!

image.png
leaden ice
#

nice!

static matrix
#

rope arm!

#

I should probably make frequency and thickness adjustable from the editor

knotty sun
leaden ice
#

step is a hard cutoff, next thing i'd do is maybe try to explore a way to make it "softer"

#

but this is a great start

#

float alpha = 1 / pow(distanceFromExpected, 3); or something maybe?

#

just exploring things 😆

static matrix
#

this is pretty good for now
got the vars changeable in the editor

image.png
#

shader code is so satisfying

#

really makes you feel like you have a lot of control over how you can make your game look
also feels like you are doing wizardry

#

(didn't capture the whole screen which is why its cutoff)

Has anyone been able to send emails through Unity?

I was trying this code:

`

    MailMessage mail = new MailMessage();
    SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");
    mail.From = new MailAddress("SENDER@gmail.com");
    mail.To.Add("RECEIVER@gmail.com");
    mail.Subject = "Feedback - " + SceneManager.GetActiveScene();
    mail.Body = "mail with attachment";

    SmtpServer.Port = 587;
    SmtpServer.Credentials = new System.Net.NetworkCredential("SENDER", "SENDER_PASS");
    SmtpServer.EnableSsl = true;

    SmtpServer.Send(mail);`

Credentials replaced with placeholders. It looks like I'm receiving the following error:

Username and Password not accepted. For more information, go to 535 5.7.8 https://support.google.com/mail/?p=BadCredentials b7-20020a170902650700b001e245c5afbfsm11939832plk.155 - gsmtp System.Net.Mail.SmtpClient.CheckStatus (System.Net.Mail.SmtpClient+SmtpResponse status, System.Int32 i) (at <7a81e51e915a4e3a83ecbb5584005dd3>:0) System.Net.Mail.SmtpClient.Authenticate (System.String user, System.String password) (at <7a81e51e915a4e3a83ecbb5584005dd3>:0) System.Net.Mail.SmtpClient.Authenticate () (at <7a81e51e915a4e3a83ecbb5584005dd3>:0) System.Net.Mail.SmtpClient.SendCore (System.Net.Mail.MailMessage message) (at <7a81e51e915a4e3a83ecbb5584005dd3>:0)

Then I found this solution as a workaround:
https://gist.github.com/marcotmp/f6dc6cfcd2d6fb73978479d04bd7b0e5

But the issue is that when I went to google to set up App Passwords, I didn't see the option anymore. Is it no longer supported? I set up 2-factor authentication as well.

So with that being said, I was curious to know -- is anyone with a gmail account able to send emails out through Unity?

I'm currently in the process of getting a demo set up for beta-testing, hence why I was curious.

Thanks!

#

That's a really bad idea unless it happens to be a Unity instance running on a server

wheat elbow
#

It's probably not the most secure if they get access to the source code, but it's just a way of me gathering feedback for now in a limited set of people with a demo build.

#

For context, I'm trying to build an in-game feature that allows the testers to give feedback as they play:

Screen_Shot_2024-04-17_at_8.44.15_AM.png
mellow sigil
#

I would rather build that form in Google Forms and have the game open it in the browser

wheat elbow
#

Unsure if there is a better way to go about it though -- this was the way I saw a few people going about it

mellow sigil
#

If you include your Gmail credentials in the build, anyone who has it can dig them from there and then you're screwed

#

How does the game send the emails if it doesn't have the credentials?

wheat elbow
#

It's a burner account that I set up to send emails from -- those are the credentials that would be present in the code.

But I'm not sure how that would be seen in the build is what I'm wondering

knotty sun
mellow sigil
#

I'm not sure what the confusion is. The game must have the credentials to send the emails. So the credentials must be included in the build.

#

If the credentials are in the build, anyone who has the build also has the credentials

wheat elbow

#

I don't know what the file structure for Mac builds is

wheat elbow
# mellow sigil I don't know what the file structure for Mac builds is

Ah no worries -- I'm thinking it might be safer for me to hold off on directly sending emails through Unity then from what I'm gathering -- maybe I can use the in-game survey to send responses to the Google Forms.

Haven't done that before so time to look into that haha.

Thanks for the heads up on that front!

#

It doesn't really matter where it is exactly, that's reverse engineering territory. What matters is that it's in there, and anyone malicious enough will find it and completely compromise that email account.

I'll see if I can connect it to a public google forms instead

If you only need it temporarily, I think just using Application.OpenURL to a public Google Forms would be easier as suggested, you dont then need to setup any webhooks or anything to send to a form - if you need a more long term solution, maybe you can look into using a database, like MySQLite, to store the feedback, you can even store additional info like the point of the level the report was sent, or the time it was sent at, how many enemies were killed when it was sent, etc

wheat elbow
chilly surge
#

Note that the above will have the same problem if you don't have your own backend sitting between (game -> backend -> database) and malicious attacker will just take your database credentials and compromise it.

wheat elbow
#

but makes sense, thanks!

#

For now I'll just see if I can collect feedback with a google forms 🙂

Can you show screenshots of how you set things up?

Also not a code problem

#

Is there a way for OnCollisionEnter to happen but prevent a physics collision?

#

In my case I want that for a piercing projectile, i want it to behave like other projectiles (deal damage on collision) but not collide

leaden ice
modern creek
#

@odd light CI/CD conversation here if you need

leaden ice
#

but the normal approach would be to use a trigger collider

elfin tree
#

maybe ontriggerenter still triggers for a collision on an enemy (collider, non-trigger)?

#

and then I just make a function and copy it to both OnTriggerEnter and OnCollisionEnter?

#

if u think that api is the best way i'll dive deeper into it

leaden ice
somber nacelle
#

apparently not

#

also why are you calling GetComponent on the singleton when that would just return the same object?

leaden ice
#

The errors don't lie

#

there's nothing to do. Get rid of the extraneous GetComponent

#

the one without GetComponent yes

somber nacelle
#

nobody said that would fix the issue. the issue is still caused by the same exact thing

#

PlayerHealth.instance is null

spring creek
#

You also had two variables named instance

#

Is your ide configured?

somber nacelle
#

that does not mean that PlayerHealth.instance is not null

spring creek
#

Show a screenshot of your editor with the top showing

somber nacelle
#

try looking at your code and show where you see it being assigned to anywhere

leaden ice
#

Pretty clearly instance is never assigned @bleak thorn

Screenshot_2024-04-17_at_13.23.05.png Screenshot_2024-04-17_at_13.23.11.png
#

why do you have two variables with almost the same name

spring creek
#

Your code editor. The ide, which I was asking abouy

#

This does not look configured

somber nacelle
#

it is though

spring creek
#

It is? Ok, well i figured it would underline the double variable error

#

Ahhhh, one is capital notlikethis

#

yeah, just a terrible theme causing poor syntax highlighting

#

How to fix that

#

Just delete one of those

how to make a physics projectile 'look towards' it's trajectory?

#

is there a physics way to achieve this or is this always simulated?

#

for example, if you imagine an arrow being shot, if it goes up and down, you'd expect the arrow to first look up and then look down

#

seems straight forward for a missile or something with propulsion since the force will guide it's 'look direction'

#

but not sure how it's typically achieved for initial velocity projectiles

cold parrot
#

there is nothing in the physics sim to simulate aerodynamics

leaden ice
cold parrot
#

You have to make that yourself

leaden ice
#

the tail has more drag than the head
so there's a net torque forcing it to orient in the way it's moving.

knotty sun
cold parrot
#

or just apply the velocity as forward

leaden ice
#

For an arrow in Unity you could hack it with like

rb.MoveRotation(Quaternion.LookRotation(rb.velocity));```
in FixedUpdate
knotty sun
#

would you not normalize the velocity?

leaden ice
#

no need

#

LookRotation doesn't care about magnitude

elfin tree
leaden ice
#

you could do it

#

certainly you could

#

it's just complex

yeah, not just like attaching two rigidbodies together, one with more drag

leaden ice
#

you'd be doing AddForceAtPosition or AddTorque to introduce the necessary torques

#

it's just... complicated. Real life physics are complicated and we're doing a primitive simulation that just looks decent

#

in reality drag forces are being applied to the object pretty much at every single position on the object

elfin tree
#

alright, the hack seems to be the common/simple way to do this

#

thx all

#

also i assume stevesmith's solution is equivalent to yours basically?

#

seems like the velocity prolly already contains that info

knotty sun
#

yep, it's basically using velocity as a direction, interesting hack, end result should be the same

leaden ice
knotty sun
#

very true, I overlooked that

leaden ice
#

But it would be a good way to do things if we didn't have a Rigidbody available

elfin tree
#

@leaden ice would you just disable the hack being called in update when it touches the ground?

#

it's kinda freaking out when it touches the ground but other than that it works great

knotty sun
#

need to disable when velocity reaches approx zero

elfin tree
#

ah ye that's a simple enough check

knotty sun
#

be an interesting test, if constantly adjusting the rotation does it affect the trajectory of the object?

cold parrot
#

It doesn’t change angular velocity but may change it if forces are applied off center of mass

elfin tree
knotty sun
elfin tree
#

seems like somthing like this kinda works
if (Math.Abs(_rigidbody.velocity.y) < 0.1f) _orientProjectile = false;

leaden ice
#

It probably would matter more if you had an off-center center-of-mass

rigid island
#

doesn't MoveRotaion ignore mass?

knotty sun
#

I'm thinking more of the physics calculation

leaden ice
elfin tree
#

makes sense, will give that a try

#

seems cleaner anyways

elfin tree
#

it still rolls a bit on the ground, so i think it hits a low velocity at some point, but then it increase again

leaden ice
#

it doesn't make sense to do this after bouncing off the ground once I think

elfin tree
#

ye

leaden ice
#

you could also use a much larger threshold for sure

#

but then it might get weird at the top of its flight arc

elfin tree
#

anything particularly bad about the previous solution?
(Math.Abs(_rigidbody.velocity.y) < 0.1f) _orientProjectile = false

knotty sun
#

bearing in mind you are not going to get much deceleration but a rapid stop

leaden ice
#

it will also stop working at the tippy top of the parabolic arc

elfin tree
#

ahh good point

#

iguess same thing but check x aswell

#

then that's kinda what velocity.magnitude does, no?

#

if (Math.Abs(_rigidbody.velocity.magnitude) < 0.1f) _orientProjectile = false;

#

maybe abs not needed there

knotty sun
#

probably best to make the threshold an inspector variable then you can play about with it to find the sweet spot

leaden ice
#

you don't need abs

#

magnitude is always positive

elfin tree
#

ye it seems to go through the ground sometimes doing this, weird

#

might just be a threshold thing

knotty sun
#

I'd be tempted to debug.log the magnitude to get an idea of the actual data involved

elfin tree
#

good point

#

magnitude seems ok

#

a bit of a mistery why it goes through the ground sometimes but i think i'll just ignore this for now

#

not the biggest of deals

#

(ground is just a plane for now also)

knotty sun
elfin tree
#

oh true ye

#

same behavior

#

maybe it has to do with the fact it's a thin cylinder

knotty sun
elfin tree
#

and it's the child of a game object

#

but at the center of it

knotty sun
#

so you are rotating from the center not from the nose

elfin tree
#

yeah i think so

#

i wonder if rotation from the tip also works

knotty sun
#

worth trying

elfin tree
#

lol it goes through the ground even more reliably

#

i'll try to do the opposite side

#

hmm, same thing

#

maybe because

image.png
leaden ice
#

yeah that should be precluded by the if statement around magnitude

#

can you show the code?

elfin tree
#

now i stop on collision

image.png
#

i'll just check if Quaternion = Quaternion.zero first

#

i can share if relevant, there's not much more to it

#

prolly this

hexed pecan
# elfin tree

Should check if _rigidbody.velocity is zero or not

elfin tree
#

oh.. yeah maybe that makes more sense

knotty sun
#

Also you need both, colision disable and velocity disable

elfin tree
#

i want it to roll on the ground though

knotty sun
#

but it doesn't need to have it's rotation controlled, physics can do that for you

elfin tree
#

oh i see what u mean

#

thought u meant something else

#

wait, why both?

knotty sun
#

just in case, you dont know which one will trigger first

elfin tree
#

i mean in that case it will always go through the ground but that was another test i was doing

#

without the .isTrigger part, only some of the time

ocean hollow
#

so much quaternion talk in one message

elfin tree
#

i guess u figured out i don't understand them at all x)

red dust
#

Okay so after an hour of testing cuz I'm a noob, if I set up a scriptable object for MovementParameters I found out that yes I do need to create a new scriptable objects for each things that calls for MovementParameters movementParameters. Cool, understand that I think. I'm trying to learn scriptable objects and how to implement them in to my game while I'm in the early stages.

But this brings me to a new problem. Let's say I make a basic enemy like a Goomba, and in its script it's calling for the HealthManager Scriptable object. Then I spawn 4 Goombas. Now they're each SHARING health even though they're all new instances of the enemy prefab, because they're all referencing the same HealthManager_Goomba. What's the way to handle this?

elfin tree
red dust
#

Ummm, so let's see, here's my HealthManager:

using UnityEngine;

[CreateAssetMenu(fileName = "HealthManager", menuName = "ScriptableObjects/HealthManager")]
public class HealthManager : ScriptableObject {
    public int maxHP = 100;
    public int currentHP = 100;
    public int healthRegenRate = 1; // Health regenerated per second
    private float healthRegenTimer = 0.0f;

    public void TakeDamage(int damage) {
        currentHP -= damage;
        currentHP = Mathf.Max(currentHP, 0);
        Debug.Log("Player took " + damage + " damage, current HP: " + currentHP);
        if (currentHP <= 0) {
            Die();
        }
    }

    private void Die() {
        Debug.Log("Player has died.");
        // Add death logic here (like triggering animation, disabling player control, etc.)
    }

    public void RegenerateHealthOverTime() {
        healthRegenTimer += Time.deltaTime;
        if (healthRegenTimer >= 1.0f) {
            int healthToAdd = healthRegenRate;
            currentHP += healthToAdd;
            currentHP = Mathf.Min(currentHP, maxHP);
            healthRegenTimer -= 1.0f;
            Debug.Log("Player regenerated " + healthRegenRate + " health, current HP: " + currentHP);
        }
    }

    public void RegenerateHealth(int amount) {
        currentHP += amount;
        currentHP = Mathf.Min(currentHP, maxHP);
        Debug.Log("Player regenerated " + amount + " health, current HP: " + currentHP);
    }
}
elfin tree
#

@red dust That's the issue

#

You 'never' want to directly change the values of a scriptable object through code

leaden ice
red dust
#

Hmm I see, so then in the EnemyStats script when it calls for a health manager, I need to store the stats separately there?

elfin tree
#

I'm not quite sure the best way to go about it but I typically will treat what your healtmanager is as "HealthManagerData" and then have another class (HealthManager) with a constructor that takes "HealthManagerData" as a param

#

also i would probably have the health in an enemy/characters's scriptable object instead

leaden ice
#

if you want to store things like max health and regeneration rate in the SO that works

#

but the current health for an individual enemy should live on the enemy itself

elfin tree
red dust
#

Hmm I see, I'm still really new to coding and I was told to try to SOs to compartmentalize things. Currently I don't even have enemies, just a player that's calling for a HealthManager and ManaManager, then a scriptable object for each

leaden ice
#

SOs are to store and configure data in nice little assets in the unity editor that can be referenced in the editor

#

not really sure how that relates to "compartmentalization"

#

classes in general are for encapsulization and compartmentalization but SOs are a very specific/special thing

elfin tree
#

yeah another way to look at it is SOs are often for 'content', so enemies, projectiles, items (they can do other things too though)

#

different configurations

leaden ice
#

You can certainly use SOs for mutable data but you'd have to actually understand how they work and be a bit more advanced of a programmer to use them that way

red dust
#

Like I said I'm a noob so probably the wrong term then. I have a player controller for a platformer that's running exactly how I wanted, so I wanted to refactor/clean up/make it easier to expand upon before I got to work on the spells

mint gale
#

im using Input.GetAxis("horizontal") and the value for it keeps increasing does anyone know how i can make it only increase or decrease when either the "a" or "d" keys are pressed (2D)

elfin tree
#

then you'd have an enemy SO to configure your enemy, and hp from it would be used to generate ccurrenthealth in your healthmanager's instance inside the enemy

#

i might be explaining this poorly though
(enemy could also be player in that explanation, or whatever it is)

leaden ice
#

(2d is irrelevant here)

mint gale
leaden ice
mint gale
#

im using it in animations to get the sprite to change when you walk or turn in a specific direction

leaden ice
#

also !code

tawny elkBOT
elfin tree
#

@leaden ice going back to the isTrigger for piercing projectiles, lets say i still want them to collide with the ground, i'm currently going for having a 'pre-ground' trigger plane to turn isTrigger back off, makes sense?

mint gale
red dust
# elfin tree i think what you call health manager should be part of either the player or an e...

That's what it basically all is right now in mono behavior with some interfaces/abstract classes for my spellcasting mechanic. I was just trying to get ideas on how I could do things differently. In my player code where I was setting up movespeed, accelerationTime and decelerationTime, I tried changing it to call for MovementParameters SO, and hooked that up to see how scriptable objects work

leaden ice
# 
    animator.SetFloat("left", horizontalInput);
    animator.SetFloat("right", horizontalInput);

Why have two params that you're just setting the same value to?

leaden ice
elfin tree
#

ah didn't think of using two colliders

#

makes sense

#

ty

mint gale
#

whenever i change directions in the game the value of "left" decreases bellow -0.01 even when no button input is being pressed

leaden ice
mint gale
#

no

#

keyboard

leaden ice
#

which is tilted or not calibrated properly

#

you may have both

mint gale
#

i dont own a joystick

leaden ice
#

gamepad perhaps

leaden ice
#

i.e. xbox or playstation gamepad

mint gale
#

it has now stopped changing when nothing happens but now decreases to bello -0.01 when i press the down input

leaden ice
#

well yes

#

-1 is below -0.01

mint gale
#

but its the horrizontal value

leaden ice
#

so "below -0.01" is a really weird thing to say

mint gale
#

yeah sorry my bad

#

-1

elfin tree
mint gale
#

im not explaining this very well

leaden ice
#

can you just show some screenshots or a video already

#

it would make this so much easier

mint gale
#

i want the image to change when i press the a key which it does as it changes the value left to -1 but left also changes to -1 when i press the s key which it shouldnt

#

i do not have video softwhere on this laptop sorry

Hi guys, does anyone knows is it possible to make game object name or little cube icon of different color like it is for prefab, or any other way to make some game objects in hierarchy tree view being distinguished from others?

ocean hollow
elfin tree
#

Would something like this also prevent physics collisions with Enemy?

ocean hollow

#

@leaden ice @knotty sun In case you guys are curious, setting the collision detection to continuous dynamic fixes the going through ground thing, might be horrible for performance but I don't know yet!

knotty cargo
#

This question might be too general, but I am making a demo game where the player moves around a planet (or, small sphere, similar to mario galaxy), but I don't really want things like escape velocity or orbit to exist. Instead, I want the player to essentially be "stuck" to the planet, and holding W (or forward on controller) would result in the character circumnavigating the object. As of now, if I move too fast over the curvature, my player will fling off. I can counter this by increasing my gravity (which pulls toward the center of the planet), but it messes up movement since it's pulling so hard.

What's a good way to A. translate movement so that it feels like the planet is spinning under you while moving (like those rolling log competitions) and B. create gravity that doesn't feel like realistic physics, but just keeps the player grounded? I could just rotate the planet under the player, but I want to incorporate a spin on the planet's axis so I can have realistic day/night cycles. In addition, this won't work as it will really show that that's what I am doing when I start having other planets/things in the solar system.

tardy crypt
#

are you doing 3d?

#

if so, one thing you could do is use spherical coordinate. apply your movement input as acceleration/decelration to angular position, and keep the radius constant.

#

if you want the player to go up down (i.e., farther/closer to the planet), you can apply a similar acceleration to radius as well, perhaps even clamping the radius to some limit of your choosing

#

up to you whether you want that to be a separate input as the forward/back.

#

or if you want to do some kind of... dynamic radius adjustment based on speed or whatever. that's where you'll have to do some experimentation.

knotty cargo
tardy crypt
#

just use a spherical coordinate system with the planet's center as your coordinate system's center.

#

you need a conversion function for Euclidean coords to those spherical coords and back

#

you can look those up on the web

#

then all you do is take your object's transform.position, convert to spherical

#

then if you want it to go around the planet, apply some change to the theta and/or phi angles

#

if you smoothly adjust, say, theta, from 0 to 360, with wrapping, the object will essentially orbit the planet

#

after each adjustment to spherical, convert back to euclidean and paply it to your object

knotty cargo
#

Got it. Thanks! Gonna go research all of that, haha!

tardy crypt
#

setting radius doesn't work because i didn't do that part right but you can see the orbit works. you'll probably have to play around with it and refine it to get exactly what you want

#

Could someone help me figure out why these two float values hpLost and percentLostCheck are evaluating to false when asked if they are >= and they both have a value of 0.2?

cFloatComparisonNotEquals.PNG
tardy crypt
#

you'll also have to adjust this for the position of your planet, as this code assumes the planet is at the origin of unity's coordinate ssytem

#

have fun

knotty sun
carmine cloud
knotty sun
#

probably better 0.01f or something similar

elfin tree
#

lets say I have a rigidbody that's already moving normally, what physics function could i use on it lets say a piercing projectile goes through it to make it either stutter or slow down a little bit, with no regards to where the rigidbody is going or the projectile direction?

#

hopefully it would be visible

#

but also not really hindering to the rb

#

(that's a bit of hail mary but who knows)

knotty sun
#

you could get the contact point of the collision and add a force at the position

elfin tree
knotty sun
#

then you would need a raycast to find a hit point

elfin tree
#

turns out a velocity multiplier seems to work

#

on one frame

elfin tree
#

but yeah addforce is prolly the better way to go about it

#

just not sure how exactly i'll do it

2 issue I'm seeing
1 mouse should not be multiplied by Time.deltaTime

#

why are you doing player.forward.rotation? instead of just player.rotation

#

is camera child of the player ? you can get rid of the yRotation on the mouse

tight pond
#

forward is the name of a transform on player where i do stuff

rigid island
#

what?

tight pond
#

player is a component that has a public transform called forward

somber nacelle
#

no, multiplying mouse input by deltaTime is not correct, even when using GetAxisRaw

tight pond
#

smoothdelta time makes it a bit better

rigid island
#

ah ok good to know thanks for clearing

rigid island
#

i bet your issue is both y rotations are not sync

#

parent cam to player and remove yrotation on cam

tight pond
#

i think also the display resolution might be something too

#

i tried too removing the player from it and just having the raw camera movement

rigid island
#

what

#

you're just gonna guess your own way then why are you asking for help lol

tight pond
#

not having part of the script where i move the camera, only rotate it

rigid island
tight pond
#

i just removed the transform.position part of the script

rigid island
#

ok that was only part of the problem

#

did you get rid of time.deltaTime on mouse?

#

turn down the sensitivity after cause it will be high

tight pond
#

i think the issue is the mouse input

#

and sens might be too high too yea

#

Ok i figured it out, it was because i had an enemy that was updating the navmesh every second causing a lag spike

rigid island
#

🤷‍♂️

tight pond
#

also the time.deltatime has no reason to be there

rigid island
#

nope

#

mouse is already framerate independent

tight pond
#

thanks for all the help, now instead of having 400 sens its a solid 3

where did you see the tris?

the batch is pretty low though

i wonder what could even have that many tris, i'm pretty much only using primitives

iirc unity tries to batch them into one mesh

i have some svg icons i turned into meshes but they are rather simple

#

oooo

#

could explain

rigid island
#

esp if you have same material / static

elfin tree

alright, well i guess there's nothing too bad there?

#

seems like the trail renderer was performing horribly

#

which i feel like that<s prolly why most people avoid using it

rigid island
#

could be

#

i barely use it myself

elfin tree
#

also how many tris is too many?

#

i don,t have many draw calls but I could get away with leaving up all the projectiles that were shot

it gets a bit crazy but doesn<t seem to cause lag which is what i would<ve expected

ofc depends on target platform too

I'm trying to implement a minimap with an orthographic world space camera and a 10,000x10,000 canvas group. But I can't figure out how to calculate for the local position of the players click relative to the canvas group, when the player clicks on a raw image that is displaying the minimap camera

latent latch
#

so you're trying to get the position from the phone map as coordinates on the main map?

#

so, let's assume the pivot is bottom left of your map, so make the phone map pivot also bottom left. Normalize the units of your screen such that you can calculate a position from the pivot and apply that offset along with the camer's pivot

#

So, say top right of the screen is 30x, 30y, and you press the center so you'd have a screen offset of 15x, 15y, then add that onto your camera pivot that could be at say -300x, -500y, and add the map's offset value to that for your world point

#

I would change to local after if you need to, but I'd stick to world values if you could

#

well, the camera map would be screenposition normalized as unit values from its pivot (actually local values on the phone would be fine too)

Just wanna say thanks again for the help earlier! Ive done a bunch of tweaking to figure this out and how I want to implement it, starting with my player stats and stuff. Im gonna put my thought process here so any feedback is always appreciated!

For example I made a HealthParametersSO scriptable object that only holds a maxHP and an hpRegeneration rate, as well as an IHasHealth interface that only specifies TakeDamage() RegenHealth() and RegenHealthOverTime functions.

Then I have a HealthManager script inheriting from IHasHealth and calling for the HealthParameters, internalizing the maxHP and healthRegenRate, and making use of the functions from IHasHealth.

Now if I make 4 different enemy prefabs, give them each the HealthManager, and attach a HealthParametersSO_OneForEachEnemy to it, they should all work the way Im thinking right?

Any bullet with some damage number could find the HealthManager of any object it collides with, and use the TakeDamage() function in that instance.

I hope Im thinking about all of that right. I figure my Player and Enemies will all use essentiallt the same "Has Health, Takes Damage, Regenerates Health" needs, so this seems like the right way to easily make things modular and expandable

lone wagon
#

Okay so now i cant drag the countdownText down, but other text i can do

spring creek
lone wagon
#

yes

spring creek
#

So that is why it doesn't work

#

TMP_Text is what you want

latent latch
red dust
latent latch
#

I treat SOs as the guts of an object such that my Enemy class has parameters (if you could use constructors with monos) that require EnemySO which defines their starting health, damage, ect.

#

Technically I only need a single Enemy prefab if the guts define everything such as rendering/sprites

spring creek
red dust
#

Sweet, thats exactly how I put it for now. My HealthManager is taking the definitions from the SO and messing with them, so that if I attach it to the player or different enemy prefabs, they all should function properly. Im slowly trying to tweak the basic mechanics I have set, now that all the movement and casting feels right, before I expand, so Im glad I seem to have the right idea so far

latent latch
#

Can always skip out on the rendering idea and define more Enemy prefab objects which is another idea

#

when it comes to pooling though, you usually want to minimize the prefabs

red dust
#

Player object, slap a health manager, enemy? Slap a health manager. Breakable barrel, slap a health manager. If it works how I think its going to, Im glad Im taking the time to refactor my code into these bits before I really get into the deep end

#

Next is gonna be breaking some of my players movement code out like this, so I can possibly reuse bits for other things. Like taking moveSpeed and accelleration/deceleration time from the main player scripts, and making them SO and setting up interfaces so that anything that ever needs to move can use those same bits

red dust
spring creek
#

So creating a new component that implements IHasHealth means no change in code, you just slap it on and it works

latent latch
# red dust Just curious, would it be wrong or make much of a difference if instead of Getti...

Interfaces can help two ways with this. For one, you can add it to different classes so say you have a IMovement interface, but you have two different methods for movement between your Player class and your Enemy class. Navmesh agent for the enemy, and physics for the player, so when you call ReduceMovement*(float amount) method it will do its own different operation depending on the type that this interface is bound to.

red dust
#

Ahhh so i should keep it to IHasHealth, so that if I make another thing like HealthManagerBoss, all the references work. I wasn't thinking about that cuz I figured I wouldn't really implement IHasHealth anywhere else, but that makes sense now

latent latch
#

The other way interfaces can help is it only exposes the properties and methods that you are meant to interact with, so your IHasHealth will not make your movement speed fields on your character's exposed when accessed.

#

So, another example is you have IEntityStats that has both Health and Movement speed, but by dividing it up into two interfaces, IHasMovement and IHasHealth, you can pass those interfaces around without exposing properties that should not be touched some of your logic

# 
float projectileDamage = 10f;
float slowAmount = 10f;

private void OnTriggerEnter(Collider collider)
{

    //is true if target is part of a gameobject with a script/component that implements IHasHealth
    if (collider.TryGetComponent(out IHasHealth target))
    {
      //call TakeDamage which is implemented with IHasHealth
      target.TakeDamage(projectileDamage)
      
      //Error: cannot access SlowMovement from IHasHealth
      //target.SlowMovement(slowAmount);

      //Alternative, check by IEntityStats to expose both TakeDamage(), and SlowMovement
    }
}```

Hmmm...I think I'm understanding a bit xD

interfaces let shit have stuff in common, without forcing them to derrive from some common garbage

lean sail
# red dust Just curious, would it be wrong or make much of a difference if instead of Getti...

how many things actually implement this interface? if only one thing implements it ever, the interface itself doesnt really need to exist. Something like health is always done the same way
There is some public take damage function, then the health script calculates its new health. You attach this script to anything that has health. Its rare that something actually needs to calculate health in a new way. You can treat a rock and an enemy the same, its just on "death" that you handle it differently.

hard viper
#

you can have 10 classes that all implement IDamageable without them having anything in common with each other. But then you can make functions that operate on IDamageables that only require the few features that they actually have in common.

#

While what the function actually does is totally different, because it’s an interface.

#

IDamageable as an interface might only have the method defined: public void TakeDamage(int damage)

#

that is it, and so that is all which must be satisfied for a class to implement IDamageable

lean sail
#

im curious as to how many people actually have more than 1 override for TakeDamage. I find interface completely unnecessary here

hard viper
#

whether that class is a player, a chair, enemy, bullet, etc does not matter

rigid island
red dust
# lean sail how many things actually implement this interface? if only one thing implements ...

The idea is that anything that can be hit with an attack and take damage IHasHealth for maxHP and hpRegenRate managed by the HealthManager, whether it's the player or a breakable object or an enemy. So I give whatever object that is a HealthManager, and anything that would hurt it can just access the IHasHealth.TakeDamage(int amount). Maybe I'm not explaining it right or maybe I am and I'm just doing it wrong still xP I'm new to this so I'm learning as I go right now lol

hard viper
#

also, you normally want to name an interface in a way that describes what you can do to it

red dust
#

So basically my IHasHealth should be more like IDamagable

hard viper
#

yes, that would be more normal

#

because having health isn’t the same as being damageable. and if something takes damage, the class that implements IDamageable can figure out wtf it wants to do with this information

#

maybe a chair is IDamageable, but has no health. It takes dmg and then instantly breaks

lean sail
# red dust The idea is that anything that can be hit with an attack and take damage IHasHea...

I understand the use of interfaces, i am just claiming you probably dont need it if you dont actually plan for things to take damage in a unique way. It sounds like you plan to use a HealthManager for anything that can take damage. This would make sense if you had another script like
BreakableObject : IDamageable but even in this case, I would just throw a health manager on the object and give it 1 hp

hard viper
#

maybe a player is IDamageable, but when it takes dmg, you need to check invincibility frames, and trigger gameover etc

lean sail
#

If you start providing this functionality on other scripts like player, rock, enemy, you run into cases where the scripts are already implementing these so you cannot have a rock with hp and one without.

#

What i am saying is basically you are going to combine composition and inheritance in this regardless, the interface isnt really needed

red dust
hard viper
#

yes

#

but that is only needed if multiple different things can be healed

red dust
lean sail
hard viper
#

in my game, i have IRadiatable (things that are affected by radiation), IBlastable (things affected by explosions), and IFlammable (things affected by fire). If it is a player class or something, the player class can figure out that if one of those functions is invoked, it can call its own TakeDamage function

#

but then I can have some objects that just get yeeted via their IBlastable interface, or some objects that crumble and get destroyed via IBlastable

#

since you write the whole interface implementation every time, each implementation is totally different, separate, unrelated

#

my blast zone monobehaviour finds objects in the blast zone, then calls GetComponent<IBlastable>(), and if the object has a monobehaviour implementing IBlastable, it invokes the IBlastable’s OnBlast(Vector2 position) method

#

blast zone monobehaviour’s job is complete. wtf the object wants to do with the information (that it is in a blast zone) is not its responsibility. Blast zone just lets everyone know that they are in a blast zone from a given spot.

#

does this make things a bit more clear?

red dust
#

Honestly I must be misunderstanding something important, so let me see if I can break this down to see where I'm having trouble.

An interface IDamagable is made for anything that would need to take damage by something else calling for its OnDamage() method

So my Player, Enemy, and a random Breakable box all have their own HealthManager that inherits from IDamagable.

if something calls for their GetComponent IDamageable.OnDamage like a bullet hitting the enemy, it sets off the OnDamage() function, which is specified on that enemy/player/box's HealthManager

That's how it's supposed to be used, right?

#

Or do I specify the OnDamage function specifically somewhere else, since they'd all use the same calculations in the end

dim matrix
#

Does Unity support HTTP/2.0? ( Mono Runtime )

red dust
#

(Also in this example, it's the same HealthManager with the same OnDamage() methods, given individually to each object)

#

Thank you btw for taking the time to explain, I'm sure this is frustrating xD

lean sail
# red dust Honestly I must be misunderstanding something important, so let me see if I can ...

Yes this is what would happen, they would all be doing the same thing.

do I specify the OnDamage function specifically somewhere else
This is up to you if you want them to do different things. But you need to be careful about where you implement this interface though. In this case you'll need like a BoxHealthManager or whatever you wanna name it, which I find will likely be unneccessary. I will explain why with a scenario
Lets say you have a box that can break and a box that cannot. Both boxes can be opened to find loot so they both have some Box script on it. You cannot implement IDamageable on this Box script, because 1 box cannot be damaged. You need to implement it on another script, like BoxHealthManager and attach this script to the box. Ok now what difference is there between HealthManager and BoxHealthManager. Nothing. The only difference is when the object dies, a player would die, a box may shatter. This can all be solved by having 1 HealthManager script with a death event. Any other script can subscribe to that death event then do what it wants

red dust
lean sail
#

This is how I have it as well. I find interfaces here unneccessary

red dust
lean sail
#

this is how I would do it as well

#

Now if you truly plan for something to take damage in a unique way, then it would make sense to use a IDamageable interface. Like an enemy that heals when damaged instead (idk how you will kill it).

#

even in this case, I wouldnt make a 2nd health script. I would have some other script handle this by changing the damage number. But this requires more setup like I have items and effects which are considered before damage is applied

red dust
#

I think what I'm getting here is that I have the right idea generally, but you thought I was doing something else that would've been a bad way to do it.

red dust
#

Or, you're saying to just cut out the IDamageable interface, and just put that code directly into the Health Manager

lean sail
#

There are other cases interfaces will be more valuable, lets take the IBlastable method mentioned by Loup&Snoop. You cannot just have 1 implementation which works, because not all objects move the same way. Simplest example of this is a rigidbody and a character controller

red dust
# lean sail interfaces shouldnt really have any code in them, just a declaration of the meth...

Its starting to really make sense now. Yeah right now my interface just holds the declaration of TakeDamage() and then I let the HealthManager determine that calculation. If everything is going to take damage the exact same way, which I assume it generally will, then cutting out the middleman with the interface and putting those methods directly into the HealthManager seems to make sense in the spirit of cutting out the extra fat.

I've seen lots of examples of people declaring things in an IDamageable and then using that for both enemies and player calculations in their managers. So that's just basically redundant is what you're saying?

I understand how it would be more useful for a setup where different things behave differently based on the same feedback though.

lean sail
red dust
#

So I'd only make the interface if, say for some reason the enemies and the player take damage on a different scale from each other, so that the Player script and Enemy Scripts could each hold their own calculations?

#

But in my scenario, since everything that has Health to be manipulated just has a copy of the HealthManager, setting OnDamage there is literally the same but cleaner?

magic harness
#

you use interfaces to ensure common functionality. So two classes that will have the same function, done in a different way perhaps will implement the interface and they can handle the logic on their own

#

With components you as defining one way of dealing with a certain thing, for all the objects that need to deal with it

#

if you are going for components, no need to go for interfaces

red dust
#

But since I'm only using the IDamageable interface in my HealthManager script, and not in any other class, it's just extra to have it there, and should all be in the HealthManager instead of the Interface?

#

Do I understand that correctly now?

magic harness
red dust

Okay okay, cool, I think I got it. I had the right idea and am on the right track, but I went an unnecessary step further with the Interface

red dust
# lean sail people may see it as cleaner to have that interface inbetween, *incase* you deci...

That's probably how I got around to having it in the first place. Somewhere recommended having the interface just as a standard.

Abstract classes are another thing I'm still getting used to. Separately for handling my spells, I have an Abstract Class called SpellBase that all my spells take from to perform their unique effects, but that's another area I'm not entirely sure I'm doing correctly in the end xD

magic harness
#

can i tell you a secret?

#

no one really does

red dust
#

Bwahaha yeah I get that xD luckily, as it stands all my code works pretty much exactly how I want. Right now I'm trying to refactor and streamline what I have so that expanding in the future is easier, hence the Scriptable Objects and Interfaces at the moment

#

I'm using an Interface ISpell that declares OnCastPressed, OnCastHold, and OnCastRelease methods, and then my SpellBase Abstract class is inheriting from ISpell, and each final spell is inheriting from the SpellBase. Idk if that's stupid or not tbh but it's working rn xD

#

(In the spirit of the naming conventions you guys explained, ISpell will probably change to ICastable or something)

magic harness
#

An advice. Take a look at your code an use an app like draw.io to put it down and look at the bigger picture, then check if you can improve stuff

#

Think about it, if a spell is already a spell, is it ever not going to be castable? Do you need that interface?

red dust
#

I thought yes, because each spell casts differently? Like one would be a projectile that shoots OnCastPressed, while one would be a shield that stays active OnCastHeld?

magic harness
#

are they still not all castable? You should have an abstract class Spell, then other classes AoESpell, HeldSpell, SingletargetSpell...

#

Cast should be an abstract virtual function

#

are you going to be able to cast other things? like items or mounts or something?

#

Another approach is to use ICastable on alls that castable and also using that to hold what castable is in a hotkey bar for example

#

Interfaces separate what a thing should do and what a thing is

red dust
magic harness
#

arent they still spells in your plan?

red dust
#

Okay so convert the interface ISpells into an abstract class Spells.

Then let's say I have Projectile Spells and Melee Spells, I'd make those classes that each inherit from Spells, right?

One step further, if Projectile spells is my base for those kinds of spells, I would then make a MagicBoltSpell that inherits from Projectile spells, and gets everything it needs, with the ability to add unique functionality to that specific spell there?

magic harness
#

Yes, exactly

red dust
#

Wow, okay so it seems like I was doing things right, just with the pieces all backwards xD

magic harness
#

If MagicBolt doesnt have anything unique that needs to differ from a ProjectileSpell, then you dont even need that

red dust
#

I figure ProjectileSpell wouldn't be a thing that's ever called, even if a MagicBolt and a FireBolt are basically the same thing with different numbers, they'd each have their own class pulling from Porjectile spell

magic harness
#

Thats just complicating things

#

Thats a step too far

#

You can create a Scriptable Object that hold information about what happens when a spell collides, and create instances of it for MagicBolt and Firebolt, for example

red dust
#

Hmmm...lost me again xD

magic harness
#

you understood where i said thats only complicating things, right?

red dust
#

In my scenario, I just want Projectile Spell to just be the base that all my projectile type attacks would use, not actually use the projectileSpell abstract by itself, or that's how I was picturing it

magic harness
#

projectile spell shouldnt be an abstract

red dust
#

Since I'm planning on varying my spells, I figured even a firebolt and a MagicBolt would have enough of a difference that they'd be their own script calling from projectilespells

magic harness
#

only spell should be an abstract, avoid double inheritance always

red dust
#

Hmmm okay

magic harness
#

projectile spell is already a type of spell. no need to take it further

red dust
#

Somehow to me, breaking it up that way sounds more confusing than how I was doing it
-Abstract Spell give the OnCastPressed,
-Projectile Spell turns that OnCastPressed into firing the spell, and then
-MagicBolt/FireBolt determines what exactly is firing and any special properties that specific spell has like an elemental type or a damage number

magic harness
#

no AbstractSpell just gives CastSpell()
ProjectileSpell defines how exactly that happens

#

MagicBolt and Firebolt dont exist.

#

those are just prefabs

#

with data

latent latch
#

it was dividing a lot of my logic from my other ability types which I wanted to use too

red dust
# magic harness those are just prefabs

In that example, let's say I need the projectileSpeed and a detonationTime (if lets say that specific spell can explode) then I can make a SO that the projectile spells reference for those variables, then on the prefab for MagicBolt, I'd give it the Projectile spell Class, and plug a MagicBoltParameters SO into there?

This probably isn't optimal I'm sure, but that would work that way?

Execution order shouldnt be solved by random delays. You can always initialize everything you want in order

Start debugging from the end: confirm that the key is not in the dictionary right before the error. Then go to where the key is supposed to be added and make sure that it's added correctly. If it is, go to every place the dictionary is modified and see if the key is removed at that point.

the unity starter asset put a namespace on their code

do you use assembly definitions for your own code?

open wasp

yeah so the easiest option here is to simply remove the asmdef file

open wasp

does that break the code at all? usually removing something is bad

somber nacelle

ahh, so this is why unity is so weird about reloading scripts

they need to remove this. maybe the editor will work better

somber nacelle

did you even read the page i linked? because that says literally the opposite

open wasp
#

i did and it says it causes the editor to only reload some files

somber nacelle
#

yes, instead of recompiling every single script when you make a change to one, it only recompiles the code in that assembly. so by breaking your code up into separate assemblies, you make recompiling faster because you only recompile assemblies that have been changed (or had references changed)

I'd rather not add a "IsTransformNull" bool to IDetectable. It  would move the null check to implementers of the interface and not throw the exception, but that then has to be implemented every time and is not obvious to the team that the need to use **Target.IsTransformNull**
Is there another way?

alternatively something like this at the callsite:

if ((Target as UnityEngine.Object) != null && Target.Transform == null)```
junior falcon

That's awesome, thanks!

Is there a way to make this DRY? I've used some extension methods in places, but this is a property. I guess I could just make it a method, GetTransform() 🤔

and not the other?

because without else your second rotate overrides the first

because it is executed each frame

Hi I have encountered problem in github.

I tried to switch branches in a github project where I chose to bring my changes to the new branches, then it got some confliction error with the new branch where it ask me to stash my changes, the stash features will mess up how the unity code sometimes, so I clicked not to stash the changes, and it makes my changes gone.

I'm not very familiar with github, is there possible for me to get my changes back?

spring flame
#

Can I AddObjectToAsset before saving a root prefab?

tardy crypt
#

basically... when you checkout a branch, that changes the contents of the working directly to match those of the branch

#

if there are changes in your working directory that were made since your last commit, those changes have to be saved somewhere or they will be lost when you checkout a different branch

#

you can either stash those changes, which stores them in a separate stash space, or you can directly commit those changes to some side branch

#

if you did neither then i think you might have lost those changes

#

git definitely has a learning curve...

This is perhaps a question regarding the Steam api, not sure. My game is about to exit EA. I want to give players a "founder's" item, that can only be found until the game's full release. After that players won't be able to obtain it. If a players uninstalls the game, but later decides to play it again, how would I know that they are eligible for the item?

#

I have not implemented cloud save, so that might be a solution.

some context- me and my friends are making a 3d top down stealth game i am currently working on a minigame similar to the wires task in amoungus, im struggling with the win condition i would like to remove my enemy ai and lasers from the scene for around 30 seconds then bring them back once the players has matched all wires.

the problem is im not sure how ive asked ai and searched for tutorials but cant find nothing that helps me any advice or help would be much appreciated

spring flame

maybe instead of removing you should disable their scripts instead?

naive swallow
# cyan hornet Imma try this

Think through your conditions. If you have pressed space this frame, or (if you have pressed up this frame while isGoindUpwards is false), you apply -RDV rotation for this frame.

If you did not press space this frame, or (you did not press up this frame while isGoingUpwards is true) you apply RDV rotation for this frame

#

These conditions are a mess and make no real sense. You can very easily satisfy both conditions, which would result in no rotation, and the first one will only ever apply one frame of rotation before the next one almost certainly undoes it

#

You should actually think through what conditions you want which one to happen under

Hello everyone,

I've been encountering a persistent issue following the addition of Unity Ads alongside IronSource/LevelPlay in my Unity project. The specific errors that manifest after downloading and integrating Unity Ads are causing duplicate class conflicts related to AndroidX libraries. I have spent the past two days attempting to resolve these with manipulate gradle files but haven't yet found a suitable solution. Has anyone else faced a similar challenge, and if so, could you share how you addressed it? Any suggestions or guidance would be greatly appreciated.

internal InputAction[] kickInputs = null;

Hello, there is a subject I am curious about. When I open any array in visual studio, it is suggested to me to synchronise the variable with nulla. What does it do to synchronise the variable with nulla? Sample code above.

tardy crypt
#

can you show the suggestion?

#

and the context? this is kind of a weird suggestion...

robust whale
#

Yes, it's a bit strange 😄 Actually, the suggestion is just this. Instead of internal InputAction[] kickInputs; it suggests me to make internal InputAction[] kickInputs = null;

tardy crypt
#

i guess if you're using it, without the assignment, it's unassigned, so it's saying you're using an unassigned variable...

#

usually you want to actually initialize the array though, not set it to null, but it depends on what your'e actually doing...

simple egret
#

It's a field, so both versions do the same (it's initialized to null). Though I haven't seen this suggestion anywhere, so it must be a setting you enabled on your code editor

lean sail
#

Sometimes suggestions are weird, sometimes it's just pointing out something you can do instead

robust whale
#

In short, it's a completely useless suggestion, isn't it? It is already initialised as null.

simple egret
#

Yes, you probably enabled a code style preference somewhere that forces you to explicit field initializations

robust whale

Hello! Had a question regarding a system I want to build in my game. Basically, my game has different days that go by, and each day you have to survive waves of enemies. I want to build something that can track all the parameters of each day like:

  • Length of day
  • Number of Waves on day
  • When the waves will change as a % of day length
  • Spawn Rate of enemies for each wave (could be anywhere from 1 - 7 spawn rate values based on the number of waves that day)
  • Number of events that will happen that day
  • Which Events Will happen (These are prefabs that spawn a special event that would make the game harder, could be 1 - 4 events each day)
  • What time each event will occur, how long the event will last, as well as any other event specific parameters (Have an event system built already, so I think I can tell that to separately change these based on the day)
  • Drops that can spawn on day (These are also prefabs that spawn but are positive and help you progress)

I was thinking of using a lot of arrays so I can edit everything in the inspector, and load everything from those arrays based on the location in the array which would be connected to the day, so NumberOfWaves[7] would be the number of waves on Day 8. This does feel like its inoptimal though and would require a significant amount of arrays which might get messy.

Does anyone know a better way to do this? I just want it to be very modular and easy to edit for testing, as well as easy to add any additional parameters should I make changes to the game.

lean sail
#

The only alternative to not storing them would be randomly choosing what a wave is at runtime, in which case you'll still be choosing randomly from a collection. Thus another array exists

warm blaze
# lean sail I am somewhat confused by your question, you're gonna have to store things in a ...

Yeah, its less about whether I should use arrays I guess, and more about making sure the whole system doesn't get messy and overwhelming. I guess its less of an implimentation question and more of a clean code question. I would potentially have 100+ days with 10+ parameters for each day and it needs to be very easy for multiple people to come in, work on, swap out values easily, and keep track of everything.

does anyone know how i can solve this animation problem.
I'm trying to use lerp to start at "0" then go to "-100" then go to "+25" then return to "0". example in image attached.
Im also trying to use a while loop variable with time duration and an animation curve to acheive this.
is it possible? i'm also thinking about Lerp.Unclamped.. but my mind is stuck

Screenshot_2024-04-18_132227.png
latent latch
#

animation curve is technically lerping

faint hornet
# latent latch animation curve is technically lerping

im tryiing to do something like this...

float duration = 0f;

    while (duration < animationDuration)
    {
      duration += Time.deltaTime;
      duration = Mathf.Clamp(duration, 0f, animationDuration);
      float eval = animCurve.Evaluate(duration);
      float value = Mathf.LerpUnclamped() <------------ stuck here
    }```
latent latch
#

is there a reason you cant use a defined curve

warm blaze
# lean sail Assuming you need to manually assign values for each day, then scriptable object...

I don't think I will have to do much with formulas. It would all be custom, so I would manually set the values of all the parameters.

Example:
Day 4 Parameters

  • Length: 180 seconds
  • Waves: 3
  • Wave 1 Change: 50% of length
  • Wave 2 Change: 70% of length
  • Wave 3 Change: 90% of length
  • Wave 1 SpawnRate: 5/sec
  • Wave 2 SpawnRate: 10/sec
  • Wave 3 SpawnRate: 15/sec
  • Number of Events: 2
  • Event Prefabs: HoxBox, MeteorShower
  • Event 1 Time: 33% of length
  • Event 2 Time: 66% of length
  • Drops: Drop1, Drop3, Drop5

Maybe I am overthinking it, and arrays for everything works. Just wanted to make sure I didn't build some giant complex system, realize it doesn't work great, and then have to rebuild it.

Plus some of it seems hard for arrays since a single day could have 3 waves with 3 different times, so I have to make an array for each wave. I could also make a jaggedarray where each day corresponds with an array that stores that days spawnrates, events, etc but then its not editable in the inspector

faint hornet
# latent latch is there a reason you cant use a defined curve

i could use a defined curve.. but i want to use the same animation curve for multiple effects at the same time to sycronize evertyhting.. so the animation curve will have a low value of -1 and a high value of +1 and convert based on that value specifically for an effect

latent latch
#

not too sure what LerpUnclamped does here, but evaluating the animation curve with the time constraint usually all I need

#

you can also create animation curves at runtime, but for smooth curves you need to play around with weights which is a pain

faint hornet
latent latch
#

right, you can use them as multipliers which I do mostly too

#

pick a range, like -1 and 1 then normalize it to some values

faint hornet
latent latch
#

well, probably some math to define what values represent what at that value

faint hornet
latent latch
#

I'd stick to 0 being 0, but if you want negative values then define a max of -1

#

such that for example -1 represents a value of -500, and 1 represents a max of 500

#

I do this because the UI for these things a little pain on the editor

faint hornet
latent latch
#

well, then you need to define some type of algorithm with those values

lean sail
#

If you're doing this all in the inspector, you just have a array or list of Wave. The wave stores it's own array or list of whatever

warm blaze
lean sail
# warm blaze Not sure what you mean exactly. If I have an array for the number of waves on a ...

Maybe I misunderstood what part you were asking about, but theres no need for any special handling of the arrays. What I am saying is that you shouldnt have an array of arrays specifically unless truly needed. It's just added confusion, what you really have is an array or list of data for the day. This will be some class. The class will then also have an array for example for the waves it has

#

Yes, by the end you can generalize it to being arrays within arrays but it's very different when it comes to readability. Also I dont think you can serialize array of arrays

warm blaze
# lean sail Maybe I misunderstood what part you were asking about, but theres no need for an...

Oh ok, that sounds pretty similar to how I started setting it up. I have a monobehavior called Days and its attached to my GameState Controller.

It tracks the currentDay, and loads all the parameters from the arrays for everything whenever the day changes, or the game is started

I guess that will work for now, and I see if it gets too overly complext. Apologies for the question, just wanted to make sure there wasn't a smarter way to do it before I go all in on setting it up.

Thanks for the help bawsi 😊

latent latch
lean sail
#

I would really just use animation curve from 0 to 1 and remap the values

latent latch
#

yeah honestly probably the better idea

#

anyway, you don't need to use lerp if you use an animation curve and evaluation every frame

#

because the curve itself is your source of linear interpolation

Collider2D.Cast is a wonderful method

i assume it is far more complex of an operation for Mesh colliders, which is why an analog does not exist for 3D

latent latch

I was thinking just insert the colliders each fixed frame from OnTrigger and clear

#

basically what you do with nonalloc overlap anyway

Actually I think nonalloc doesn't clear but just inserts that amount of colliders which is why it returns a counter

Write your own physics engine that has a separate feature to join objects together

runic nimbus

Okay haha

hard viper

I did that. literally took me 2-3 months. it works

#

…or you could use a joint

runic nimbus
#

Uh okay

#

Anyway I think I got it

#

@hard viper If I separate all of the colliders out under a phys object, I can move this back and forth to whatever I'm attaching

#

That works

#

But that's just parenting and defeats the purpose

#

I'll try to see if I can get around the parenting restriction

Guys how do you make tiles bigger in unity tilemaps

20240417_201553.jpg
tardy crypt
#

it's a bit complicated. at base, a tile is a scriptable object that you can i believe spawn as a menu item in your assets panel

#

you can configure all your tiles that way

#

then there's a tilemap pallette that you can add any number of tiles to

#

and then you can paint them in the editor or add them at runtime with specific tilemap methods

#

you can define specialized tiles by inheriting from tile or tilebase

#

you can also put a specific attribute on those tiles to add a menu item to add such tiles to your assets panel

fervent arrow
tardy crypt
#

i'm pretty sure "size" would be part of the tilemap itself

#

all tiles, i believe, have the same size

#

your tilemap can have sizes with respect to world units

#

give me a sec i'll check it out for you...

fervent arrow
#

Im booting up unity to check something

tardy crypt
#

basic tiles have pretty much just a name and a sprite iirc

#

i should just keep a blank project open to answer these questions because unity takes forever to create a new project...

#

oh they expanded on this a lot since the version i used. it looks like the game mostly just assumes a 1:1 correspondence between tilemap tile size and world units, unless you specify a custom orientation, in which case you can adjust scale for example.

#

maybe i just never used their built in advanced tile types...

In Fusion, there are networked properties. These are okay to modify any time and you can be sure that it will appear on everyone's client even if there's an issue with sending it when you change it.
Transform hierarchies, are not networked. You can get it right most of the time by setting the parent during an event everyone will recieve, but it is not guaranteed to be sent over network.

#

That's how I understand it. Now I am consulting them on how I might get around that limitation.

hard viper
#

the core issue is having separate rigidbodies

#

you can make an object with a rigidbody, and many child objects with colliders and no rigibody. Then all the child colliders get “combined” in a way to the one rigidbody

#

that works. but if you try to give the children and parents both rigidbodies to move freely, but also coupled, you will have a big big problem

#

joints are like a constraint on physics simulation to basically say “if these two rigidbodies do not have this relationship of position/rotation relative to each other, apply this much force based on how wrong it is.” with a force that is normally very large

#

it’s like a spring, basically. Apply force to X object based on how far it should be from a given relative position to Y object

Bruh all i needed to do was change "Pixels Per Unit" to 6

#

if you set the force to be massive, with infinite break force (ie it cannot break), then you are effectively “welding” two objects with a given relative positioning to each other
