Then just drag it to your character... Nothing else

[steep rose]

Keep in mind you need to calculate friction forces or else your character will slide

[dry tendon]

And change friction on inspector

[regal bear]

Can't drag it to my character

[marble hemlock]

nothing is wrong with the code but its been saying scalar calculations are faster than vector calculations?

is that... necessary?

[dry tendon]

Or not to your character, is it possible to drag it to the RB component in your character?

[slender nymph]

it gives slightly better performance. it's basically saying to group up the float multiplications

[dry tendon]

Basically the component that is giving physics to your capsule

[marble hemlock]

i dont really understand what its referring to

the scalar calculations i mean. i'm not sure how i'd do that.

[regal bear]

i don't have RB. I use character controller, and i guess physics is written in my code. I used some external code that i found i tought it can work since im beginner at coding, i don't think i can handle physics

[slender nymph]

instead of doing something like Vector3.one * speed * Time.deltaTime it's saying to do Vector3.one * (speed * Time.deltaTime) (this is just example code, not what you should be replacing your code with)

[regal bear]

i used some code from ChatGPT.

[slender nymph]

this results in fewer multiplication operations since multiplying a Vector3 results in 3 operations. so Vector3.one * speed * Time.deltaTime would break down to Vector3.one * speed which is 3 operations, then the result of that * Time.deltaTime which is 3 more operations for a total of 6 multiplication operations.
Vector3.one * (speed * Time.deltaTime) breaks down to Vector3.one multiplied by the result of the second set of multiplications so a grand total of 4 multiplication operations

[dry tendon]

Oh, then my bad... No idea about physics by code at the moment, I usually use physics, don't really think is that hard to use them, just watch any simple tutorial and you'll get basics 😜

[regal bear]

Oh good i'll do that.

[dry tendon]

Perfect!

[marble hemlock]

tryna wrap my brain around this a bit

[slender nymph]

remember that a Vector3 is 3 floats. when you multiply a Vector3 by a float it results in (x * scalar, y * scalar, z * scalar). it does that for each multiplication. so instead of multiplying your Vector3 by two separate floats (the scalars) which results in doing that operation twice meaning 6 total multiplication operations, you multiply all of your scalars together then mulitply the Vector3 by the scalar. resulting in fewer multiplication operations.
remember that multiplication is commutative so it doesn't matter what order you do the multiplications in, it ends up with the exact same result either way

[marble hemlock]

OH

[slender nymph]

so let's use some actual values with my previous example. Vector3.one is obviously (1, 1, 1), we'll call speed 2, and Time.deltaTime can be 0.02.
so Vector3.one * speed * Time.deltaTime is (1 * 2 * 0.02, 1 * 2 * 0.02, 1 * 2 * 0.02)
Vector3.one * (speed * Time.deltaTime) simplifies to Vector3.one * 0.04 which is (1 * 0.04, 1 * 0.04, 1 * 0.04)

[marble hemlock]

wait my brain is trying to catch up now
so for each thing vector 3 has to multiply by, it multiplies all the axis by those values, so speed and Time.Deltatime are things it has to do separately

[slender nymph]

Yes

[marble hemlock]

and then putting the parenthesis around the others will tell it to solve that first, and then multiply that (almost final) value to the Vector3

[slender nymph]

yes

[marble hemlock]

thank you

[stone pilot]

Can someone help , How can I fix this ? the ball doesn't stop moving isnt there something I can do with the rigidbody ?

[summer stump]

Could add physics materials with friction

[stone pilot]

I have one But the problem is what do I have to set the friction value ?

I've set it to 0.1

[summer stump]

.1 is very low

If you want more, increase it

[stone pilot]

Alright

[summer stump]

Also, you can add physics materials to the ground as well

Or set the friction mode to max or something

[stone pilot]

I've set to 1000 and still not workin , I'll try addin one on the ground

still not workin...

[summer stump]

Then likely a movement code problem

[stone pilot]

Alright thx

[stone pilot]

I fixed it, I just increased the angular drag

[sullen perch]

am trying to bake my mesh but i csnt click on navigation pls help

[languid spire]

do not cross post

[sullen perch]

wdum?

[languid spire]

do not post the same question to multiple channels

[sullen perch]

ok

[languid spire]

The navigation tab needs to bo opened. Window->AI->Navigation

[sullen perch]

i dont have a ai option

[languid spire]

Did you install the AI Navigation package?

[sullen perch]

how do i do that?

[languid spire]

package manager

[mint remnant]

is there like an event that fires whe a Grid Layout Group has completed adjusted items inside it?

[sullen perch]

i still cant select it

i think i need to import nav mesh components but i dont know how to

[steel stirrup]

I don't believe so, but this shouldn't really be something you ever need to do. How did this come up?

[mint remnant]

seems there is one quite undocumented one OnCanvasGroupChanged()
having an issue moving a tranform to the position of another one at load up. Once it's up and going and I scroll mouse wheel it jumps right into the proper place

[steel stirrup]

show code for how you're moving it, because this is definitely not the way to solve it lol. And your grid layout group settings

[sullen perch]

ye but i also need to download a navmesh component for the tutorial im following but idk how to do it, its from github

[languid spire]

This packages replaces the old Nav Mesh Components system

[steel stirrup]

this tutorial is probably massively out of date

[mint remnant]

        float scroll = Input.GetAxis("Mouse ScrollWheel");
        if (scroll != 0)
        {
            if (scroll > 0)
                slotIndex--;
            if (scroll < 0)
                slotIndex++;

            if (slotIndex > itemSlots.Length - 1)
                slotIndex = 0;
            if (slotIndex < 0)
                slotIndex = itemSlots.Length - 1;

            highLighter.position = itemSlots [slotIndex].icon.transform.position;
            player.selectedBlock = itemSlots [slotIndex].itemID;
        }
```https://gyazo.com/0e63805c99abb0798f102c46001c4c95

[sullen perch]

ok

[dry tendon]

Why is it not detecting the gallery button? https://paste.ofcode.org/R6fnmSpR5RunDQAdf2dHgu

[sullen perch]

but i still can use navigation

[mint remnant]

oh forgot to mention that chunk of code is in Update

[steel stirrup]

alright, and I'm guessing your highlighter is just using layoutelement.ignorelayout?

[steel stirrup]

it goes to the right spot after you move, but not on instantiation, correct?

[dry tendon]

When i click the first button it leads me to another menu, but then it doesn't detect me any button in the second menu...

[mint remnant]

yea, and if I put in that weird undocumented OnCanvasGroupChanged() the same position line of code it goes to the right spot, but if I maximize the game screen it's in the wrong spot again and only when I scroll the mouse does it jummp to the right spot. not using any layoutelemnt ignored thing

[steel stirrup]

so this code is probably irrelevant, check how you're instantiating

[mint remnant]

not instantiating it, it's just an image on the canvas

[steel stirrup]

oh, it's just your rect tranform not being set up right

[mint remnant]

public RectTransform highLighter;

[steel stirrup]

no in the actual inspector

you're not setting up your anchors to keep it where you want

[mint remnant]

https://gyazo.com/0e7f12863db508603e09f6a8ea1ab517

[steel stirrup]

so when the canvas changes size it wanders off

[steel stirrup]

you should go to #📲┃ui-ux and post your full hierarchy, because it's impossible to fix without

[mint remnant]

well I kinda was just putting it anywhere and moving it to the right place via code

[steel stirrup]

that's fine

but dont be surprised when 'anywhere' is not the right spot to start

[mint remnant]

ok I might try over there then, I'm admittadly pretty newbish on UI

[steel stirrup]

To make your life way, way easier just add a layout element, select ignore layout, and child it to your grid. At least then it will always be positioned relative to your grid

[mint remnant]

Cool, that alone solves it for both initial load and if I maximize game view 👍

[steel stirrup]

Great, I'd recommend reading up on recttransform, pivots and anchoring though or this will absolutely be a running issue

[dry tendon]

Any ideas?

[umbral rock]

Learning what Mathf.Atan2 does and is, i wonder if u could write this as Mathf.Atan2(relative.z, relative.x) * Mathf.Rad2Deg;
if it would do the same and have the same outcome as they write it in the picture?

[pallid nymph]

swapping x and z would give a different result, if that's the question

[umbral rock]

why? he calculates the angle between x and z right? thats the same as calculating it between z and x?

[cedar bone]

How would I get the rotation for one vector3 to look at anther vector3?

cause im trying to instantiate a projectile to go towards where the player is looking.

[raw token]

Atan2 is the angle between the x-axis and the ray to the point at the coordinates given by the argument.

So x and z there are floats representing the coordinates of a single 2D point (or two sides of a triangle). There's no such thing as "the angle between two lengths."

The angle to 2,1 is like ~30 degrees while the angle to 1,2 is ~60 degrees

[umbral rock]

but why cant u switch the two then? it stays the same doesnt it?

[night raptor]

because 30 and 60 are not equal

[umbral rock]

so x is always 1? or?

i dont quite understand the math behind it lol

i know it calculates angles

but i dont understand why u couldnt switch the z and x in this picture

[raw token]

Edit: I messed up the Atan2 arguments in the illustration below - they should be reversed

[umbral rock]

the 1,2 is the 1 the x axis and the 2 the y? or the z?

[cedar bone]

I don't want my bullets to go through thin walls, but I don't want it to use rigidbodies cause of lag. How would I make it constantly go forward?

[languid spire]

lerp

[cedar bone]

but If I make it run every frame, and in between frames it goes through walls. How would lerp help?

[raw token]

In 1,2 - 1 is the horizontal coordinate and 2 is the vertical (I just wrote it in that order out of habit)...

Mathf.Atan2() takes the vertical then the horizontal as arguments. But which components of a vector which you pass in might change depending on what you're doing - Atan2 works on a two-dimensional plane, but that plane can be anything

[night raptor]

Raycast/Spherecast one step each frame so the whole path will get traced on the way

[cedar bone]

also if I set my rb to kinematic is there even any lag?

[umbral rock]

thats what i mean, in the code above i need to check the angle between z and x coordinates and then rotate the player to that, but i dont understand why he puts the x in the y argument and the z in the x argument

[languid spire]

no

[night raptor]

why would rigidbody cause a lag to begin with? do you have hundreds of them flying at the same time?

[cedar bone]

its bullets

so for smthing like an AR

im guessing it would

[night raptor]

I'm not so sure about that. Bullets are quite fast so not many will be flying/simulated at once

[tall lodge]

Have you tested it to see if it causes lag before trying to come up with an alternative? In my experience, any performance issues with bullets comes from not pooling them

[cedar bone]

do u reccomend setting interpolation to continues cause its fast?

[night raptor]

interpolation doesn't matter, it only changes the visuals, not the physics. the collision detection mode is what you likely mean and yes, it should be set to continuous

[languid spire]

you know you are allowed, indeed should, test things yourself to see if they work with your use case

[cedar bone]

to be honest i havent really noticed a difference

but thats y i was asking here

[raw token]

There's no such thing as "the angle between the z and x coordinates..." Coordinates define a single point. Atan2 retrieves the angle from the positive horizontal axis to the point.

By passing x, z in, you're treating the x-axis as the vertical and the z-axis as the horizontal... So you're retrieving the angle from the positive z-axis to that point. In the code you've posted, it's "the angle from this object's transform.forward to the target"

That order gives you an angle on the x/z plane, measured from the positive z axis

[umbral rock]

what would happen then if u switch them? u rotate to the wrong angle?

[raw token]

Yeah - my brain is spaghettifying at this point, but I believe then you'd get the angle to the target from this object's transform.right (it's positive x axis). Totally valid if you want an angle to which would rotate the thing such that it's right side faces the target 👌

But maybe try it and see?

[umbral rock]

well, my brain isnt braining anymore by now lol

that is such a hard thing to understand

[keen needle]

This should shoot straight right? For some reason shoot at a 45º angle

I have tried both

[languid spire]

whats wrong with

shotpoint.forward * speed;

[keen needle]

not working

[languid spire]

not a very helpful reply

[keen needle]

shotpoint rotation is 0,0,0

and bullet prefab same

Keep shooting at a 45º angle

[frank flare]

how can I spawn something through script from assets on a spawner object?

[umbral rock]

with the atan2 function, is the x axis always 0 and the opposite 270 or -90?

[wintry quarry]

            if (itemToSpawn.name != "Shit")
            {

            Debug.Log(lastSpawnTime);
        }
    }*/
}

how can I spawn 3 times with a delay of 0.5 seconds if the itemToSpawn is Shit?

do I have to create coroutine or what?

[wintry quarry]

If you want a delay in your code you either need a coroutine, async, or to use a timer variable that you increment and check each frame

[lost basin]

I have a problem with my seed. I have made it so that the seed is the same as a random number I'm generating, but the map does not change with the new number, only when I edit it manually in the editor. The seed that's currently generated is actually 8.

[lost basin]

Forgot to say thank you for helping me last time, the mesh collider works👍

[languid spire]

Serialized values in the Inspector will ALWAYS take precedence over values in the code

[frank flare]

else if (itemToSpawn.name == "Shit")
            {
                Instantiate(itemToSpawn, Items.transform);
            }

what's the best to use here to spawn Shit 3 times with a delay of 0.5 seconds?

[wintry quarry]

Either start a coroutine with a loop or using a timer variable and mentioned and incrementing a counter

[frank flare]

I think best is coroutine with a loop, how do I do it?

[tall lodge]

https://docs.unity3d.com/Manual/Coroutines.html

[wintry quarry]

Do what? Which part?

[lost basin]

So should I change the value to not be serialized? Or remove it from the inspector?

[languid spire]

if you want to use the value set in code it cannot be serialized

[lost basin]

Okok, I have to completely honest, I do not know how to change that🥲

[languid spire]

is it a public variable?

[lost basin]

It is a public int

[languid spire]

so change it to private or, if it needs to be public, change it to a property

[lost basin]

Okok I'll try that, thank you

[frank flare]

Debug.Log("Key was just pressed");
            lastSpawnTime = Time.time;

            GameObject spawnedObject;
            if (itemToSpawn.name != "Shit")
            {
                spawnedObject = Instantiate(itemToSpawn, Items.transform);
                spawnedObject.transform.position = spawner.transform.position;
            }
            else if (itemToSpawn.name == "Shit")
            {
                IEnumerator Fade()
                {
                    for (int i = 0; i == 3; i += 1)
                    {
                        spawnedObject = Instantiate(itemToSpawn, Items.transform);
                        spawnedObject.transform.position = spawner.transform.position;
                        yield return new WaitForSeconds(.5f);
                    }
                }
                Fade();
            }

I tried this way but it doesn't work

how?

else if (itemToSpawn.name == "Shit")
            {
                IEnumerator Fade()
                {
                    for (int i = 0; i > 3; i += 1)
                    {
                        spawnedObject = Instantiate(itemToSpawn, Items.transform);
                        spawnedObject.transform.position = spawner.transform.position;
                        yield return new WaitForSeconds(.5f);
                    }
                }
                StartCoroutine(Fade());
            }

idk

I have no other ideas now

[lost basin]

I make it private, but the map stays the same. I've tried to make it a property, not sure if I'm doing it correctly, but that doesn't wortk either. I've tried using it as a property while its private and public and nothing seems to work, what would your next suggestion be

[umbral rock]

so if i understand this code correctly, the atan2() takes the input from the horizontal input and the vertical input then converts it into degrees and then the transform.rotation tells the object to rotate x degrees around the y axis, and the x degrees is the outcome u get from the atan2? is that right?

[languid spire]

so you still have your public int seed ?

[lost basin]

Just made it private, still doesn't work

I would send the whole code but it's about 200 lines of code

of course not, what you need is

You're setting your seed in Awake, but getting the RandNum in Start. So you get the random number after you've already set the seed.

i'm making a 2d platformer, but there are hundreds of tutorials to make one. been looking through some, but all are different.

is there a base which you guys advice to use? one with most of the basics (coyote time, input buffering etc.)

[lost basin]

The rest of it is for noise maps and things like that, generating the mesh. Should I make a new script for the seed?

I don't know if this has been covered here before, but the free version of ChatGPT is very good at answering questions about coding in Unity. At least for simple questions. I think it would solve a lot of problems for newbies in this chat, instead of waiting for an answer or asking again and again.

[silk night]

for simple things maybe but you are better off not using chatgpt

it can straight up be malicious in what you are trying to do and when you dont have the knowledge to filter good from bad info yet its not a good idea

[pearl garden]

how do i make circlecast ignore a kayer

[silk night]

You can input a layermask which has all but that layer

or make a layermask with only that layer and reverse it, then input it, easier if you add more layers

[pearl garden]

im kinda scared of doing that

[silk night]

whats scaring you? 😄

[pearl garden]

too many G.o

[silk night]

just do a public LayerMask, which lets you pick the layers in the inspector, then reverse it, i belive reversing a mask was mask = ~mask;

[modest dust]

Choose one, watch it, research what it doesn't cover. You won't find a perfect tutorial showcasing exactly everything you need. Or even better, break down the kind of game you want to do into separate mechanics and research them individually if you don't know how to handle them.

[umbral rock]

i dont rly understand what atan2 is, i understand that its to calculate angles but first they say the arguments are (y, x) and then they say the arguments are (x,y)?

Why did my falloff map stop working
https://hastebin.com/share/kebiyenexo.csharp

[modest dust]

If you get yourself a pencil and a piece of paper and visualize it, you'll see that x and z are one both the "ground plane".
And yes, direction.x would be the vertical axis, direction.z is the horizonal axis. The rotation then results in rotating towards the target

If you're having a hard time visualizing something, it's always an option to just code it in and see by yourself how it works

[umbral rock]

so the y in atan2 is not actually the y that brings your object higher up? its the vertical line if u look from above your object? and the top of the vertical line, is that always 0°? and then right is 90° then -180° etc..?

[modest dust]

The y is your "y" relative to the plane you're working with

xy yz zx

[umbral rock]

okay

still dont understand it tbh

[modest dust]

Look at one wall in your room and then at the wall next to it

[umbral rock]

i thought if u look from above to your object u have the vertical and the horizontal and u set the direction.x = to that vertical line (y) and the z to (x) and then if u look straight ahead its 0° and if u go right u look 90°

[modest dust]

One would be in xy plane, the other in zy plane

[umbral rock]

yes

[modest dust]

Unless you have walls at weird angles, but these are still 2D planes

[umbral rock]

indeed

[umbral rock]

isnt this a right conclusion?

[modest dust]

The short version is, as far as I'm aware: atan2(y, x) -> z rotation, atan2(y, z) -> x rotation, atan(z, x) -> y rotation

[modest dust]

Not from above, but from a certain perspective to see one of the planes

Right axis is 0°

yes i know this, but what my explanation right or wrong?

[umbral rock]

huh? right axis is 0? but in my tutorial he sets the y argument = the direction.x? and the top axis is 0° for him

[umbral rock]

how so not above? what certain perspective then? im in a 3d scene rn btw

[verbal dome]

Maybe you unchecked useFalloff in the inspector 🤷‍♂️

can someone help me setup vsc for unity it doesnt work for some reason

I think there's was option somewhere to switch the scene editor cam to change view perspective to view one of the planes, but I'm not sure if I'm not confusing it with something else right now, and I'm not anywhere near my PC to check

Basically image yourself aligning with one of the axis, so that you look in the same direction as the axis is pointing

[umbral rock]

i thought i understood the function but the more u explain the function the more chinese it gets for me lmao, its not that i dont know what atan2 is its how and what to give in the arguments, u have to pass in a (y,x) but i dont understand why my tutorial passes the direction.x and direction.z in it?? why would u do that? he also said atan2 sees the object from top down view and the u have a vertical line and a horizontal line, the vertical line is the y and the horizontal the x, that makes it easy for me to understand why u set the direction.x equal to the y argument because u want to go forward and by 0°...

[frank flare]

I'm using official unity asset character controller (using first person controller) why when I'm trying to slowly aim it's not aiming?

this is the script
https://pastebin.com/SgCeNYAj

[modest dust]

atan2(y, x) where x is on the axis that's 0°

So if atan2(direction.y, direction.z) Z axis is where it's 0. If you flip it around you'll just get an angle with an opposite sign if I'm not mistaken (so 30 instead of -30 for example)

[frank flare]

the problem is that it just can't aim slowly

[umbral rock]

he sets it like this atan2(direction.x, direction.z) so ur saying that the x argument(direction.z) is where its 0? that would mean to the right is 0????

[modest dust]

I'm bad with verbally explaining math, it I were next to you I'd just do a few hand explanations and you'd probably get it lmao

[frank flare]

the script is confusing idk how to fix it

[lost basin]

I didn't unfortunately, wish it was that simple. I seems like the mesh collider is off (like not in the right position) now too? Even if I use the falloff map

[umbral rock]

oooh, so he actually tells atan2 that the y axis is the direction.x so left and right and the x axis wich is 0° is the direction.z so forward and backwards, and thats why forward is 0° because he says the x is the z axis?

[modest dust]

Easiest to explain would be with an example.
If direction.x is 1 and direction.z is 0 then atan2(1, 0) = 90°, which means that if you're rotated as such that you're looking straight at the z axis, you need to rotate by 90° to look at the target.

[lost basin]

It's the right shpe, but orientated wrong

[mint remnant]

is it off rotation by 180?

[umbral rock]

yes i completely understand this, but i dont understand the arguments, because in the explanation its (y,x)? do they mean the y axis and x axis or just 2 axis and if u put the axis in the x argument its gonna have that 0°?

[modest dust]

Don't think of y and x as the literal y and x axis in unity

Just relative to the plane you're looking at

[umbral rock]

oohh lol, its just 2 axis that u choose?

[modest dust]

Yes.

[umbral rock]

aahh so the y argument is not the y axis, its just like saying atan2(x1, x2) 2 axis?

[modest dust]

Yes

[umbral rock]

lol, i completely misunderstood :/

so the axis u put in the x is gonna have 0°? so in this case its z so forward is gonna be 0°

ig?

yes

[modest dust]

Pretty much

[lost basin]

Yes

[umbral rock]

oof, thank u very much, im pretty bad at maths and i rly need to improve it... thanks for the explanation lol

[mint remnant]

Sebastion doesn't cover this in his tutorial, but the color map never lines up with the noise generation, it's due to the plane needing to be rotated about the Y axis 180 because the linear array is filled from 0,0 being in that upper right corner instead of the bottom left like the docs say it is

[modest dust]

No worries, I'm not an expert at math either, just don't take what you read too literaly, math is abstract and can be applied in many different scenarios

[mint remnant]

sorry, corrected that, I meant Y axis

[frank flare]

maybe it's a line with _cinemachineTargetPitch = ClampAngle(_cinemachineTargetPitch, BottomClamp, TopClamp);
what does ClampAngle do?

[swift canyon]

Hi, really new here and in need of some help, currently I want to rotate my top half of my model to where my mouse is currently at, but for some reason the back of my model always follow the mouse not the front, and the model is not rotating properly either. I really need the help, and for those who will look at it thank you 🙂
Code for the mouse follow: https://pastebin.com/YFDVBcav
Note: already added an empty object to parent my top half of the model it did fix the issue where the model is facing up when rotating

[frank flare]

the problem is basically that my camera aim isn't sensitive enough

[lost basin]

Nvm it work

[strong wren]

was this

ChildScream = ChildScreams[randScream];

this is the line thats causing me trouble

it still lets me play and its an error that pops up only sometimes?

            ChildScream = ChildScreams[randScream];
            Child.clip = ChildScream;
            Child.Play();``` heres tghe thing that includes randscream

maybe itl help idk

[languid spire]

the only way that will cause that error is if ChildScreams has a length of zero, i.e. is an empty array

[strong wren]

yeah but the thing is dont arrays 0 index/

it starts from 0

[languid spire]

yes, but if Length =0 array[0] does not exist

[latent granite]

Hi, i am kinda new to unity and i wanted to make a simple 2d shooter game to practice some things i learnt. i have a square with movement and jumping scripts and also interaction. but i wanna add a gun that follows the cursor but i dont really know much about rotation and cursor tracking

[strong wren]

so should i change the 0 to 1?

[languid spire]

no, check for zero length before executing the code

[strong wren]

so an if statement?

like if lenght = 0 then idk

[languid spire]

yes, how else ?

[strong wren]

but like what do i tell it to do then....

like yes if lenght = 0 then do specificly what?

[languid spire]

nothing

[mint remnant]

or print out the value just before accessing the array to at least see what it is trying to access

[strong wren]

so im just putting an empty if statement?

[languid spire]

you can do if length > 0 // Do the code you have

[mint remnant]

maybe you filled hte array in playmode and restarted it and it went back to empty

[strong wren]

actually i think i found the issue

the array was somehow cleared?

i have 4 diff enemies and 1 of the enemies array had an empty array

yeș

sorry for wasting yalls time

thanks for the help tho

[lost basin]

where do I find this error so I can try and fix it, I know in what script, just which array should I be looking at

[pliant sleet]

can you help me with this camera setting ? I accidentally hit a button and now my camera movement is kind of odd so I want to revert it back but I don't know how.

[languid spire]

read the second line

[mint remnant]

double click it, should open the code at the error

[lost basin]

Is it line 32?

[cosmic dagger]

only one way to find out . . .

[languid spire]

what do you think?

[mint remnant]

that or the computer got it wrong

[latent granite]

i wanted to make a simple 2d shooter game. i have a square with movement and jumping scripts and also interaction. but i wanna add a gun that follows the cursor but i dont really know much about rotation and cursor tracking.

[lost basin]

maybe🤭

It works now thank you

[frank flare]

click the cube in the middle. you enabled orthographic camera

basically a 2d camera

[pliant sleet]

thank you

[frank flare]

np

[frank flare]

this problem isn't gone even tho I tried to find the problem in the code

[deft grail]

rotate the Z, you can find the direction from gun to mouse by subtracting their positions

[latent granite]

i tried to track the mouse position but it doesnt work. its giving me an error that says object reference not set to an instance of an object

[deft grail]

show code, but something is not assigned

[frank flare]

Nvm I figured it out now, I just had to change this variable

[latent granite]

here it is

[deft grail]

did you assign mainCamera in the inspector?

[latent granite]

😅i forgot to.its working now though. but how do i make the gun follow the cursor now?

[deft grail]

need to change the guns rotation based on the direction to the mouse

[latent granite]

can i use Vector3.RotateTowards?

[lost basin]

Why do the colours only render if I update the script manually?

[mint remnant]

Did you include his code for public override void OnInspectorGUI() ?

need to watch his videos end to end a few times, he covers tons of details in that series

[umbral rock]

im following a tutorial and i should be able to look left and right but i cant? anyone knows why

[mint remnant]

xRotation -= mouseY?

[umbral rock]

ye to rotate around the x axis

[lost basin]

I'm sure I did, I just don't remember in what script that is

found it

[latent granite]

this is what i was able to make so far. how can i fix what's happening here?

[lost basin]

I did, but it's not working. Very strange.

[deft grail]

probably rotating the wrong axis?

[latent granite]

its rotating on all axis. ill try to lock rotation on the z axis

[deft grail]

you only want it to rotate on 1, cant remember if its X or Z or what

[ivory bobcat]

Maybe consider showing the !code

Remove Time.deltaTime - Brackey made a mistake.

Other than that, make sure the player variable has referenced the Player body object (not the camera) - assuming this component is on the camera.

[mint remnant]

I keep seeing this but even the unity docs shows multiply by time.deltatime, have a good link to why you shouldn't?

[latent granite]

i tried "transform.eulerAngles = new Vector3 (eulerAngles.x, fixedRotation, fixedRotation);" but its giving me an error on eulerAngles.x i wrote the same line of code in another script and it worked. also, fixedrotation is set to 0

[ivory bobcat]

Get Axis is already normalized and relative to the delta. You do not need to interpolate it further relative to time.

The main doc should have discussed this.. one sec.

[mint remnant]

it says this: This is frame-rate independent; you do not need to be concerned about varying frame-rates when using this value., then they turn right around and multiply by time.deltatime....go figure

[ivory bobcat]

If the axis is mapped to the mouse, the value is different and will not be in the range of -1...1. Instead it'll be the current mouse delta multiplied by the axis sensitivity. Typically a positive value means the mouse is moving right/down and a negative value means the mouse is moving left/up.

This is frame-rate independent; you do not need to be concerned about varying frame-rates when using this value.

Get axis can be mapped to buttons or mouse. If it's mapped to the mouse, you do not need the delta variable because it's already a delta.

https://docs.unity3d.com/ScriptReference/Input.GetAxis.html

[mint remnant]

yes and then they do this
// Make it move 10 meters per second instead of 10 meters per frame...
translation *= Time.deltaTime;
rotation *= Time.deltaTime;

[short hazel]

The example binds WASD as axes, not the mouse

[mint remnant]

ah!

[night raptor]

The second example uses mouse and there's no deltaTime

[ivory bobcat]

Theirs was relative to buttons (horizontal and vertical)

[mint remnant]

interesting and confusing all at once lol

[short hazel]

The physical explanation is: you moved the mouse X centimeters over Y seconds. Whether at 60 FPS or 3 FPS this doesn't change, so it's framerate-independent!

This is also valid for the new input system IIRC, the mouse movement is also passed as a delta so no need to multiply by deltaTime

[ivory bobcat]

With the delta time removed from the equation, you should be getting more responsive results. If nothing is still happening, you've likely referenced the wrong object as the Player.

[umbral rock]

i have a weird bug with my camera when i move with my player (wasd) my camera spins around like crazy

So I have these 2 lines
transform.Rotate(Vector3.up * Input.GetAxis("Mouse X") * Time.deltaTime * mouseSensitivityX);
verticalLookRotation += Input.GetAxis("Mouse Y") * Time.deltaTime * mouseSensitivityY;

And I tried taking out the Time.deltatime. Had to adjust mouseSEnsitivity to no avail and the camera goes nuts

Hello! My game is working perfectly fine in the editor NO errors NO bugs nothing but when i build the game some triggers are not working like they should be and an object is missing.

[lost basin]

Gindipple🤭
Would you mind helping me with the map not rendering, if you have any idea as to why It's not rendering when I start my game.

[frank flare]

can someone tell me how to randomize float?

[mint remnant]

Best if anyone available can help, sometimes others see things that someone else doesn't. But in general, show code and ask question. Sebastion's code is all on github, did you start with that or type it in as you watched the videos?

[lost basin]

"name of float" = Random.Range("Min value","Max Value");

[frank flare]

ok

[frosty hound]

Inb4 they copy that directly

[lost basin]

Just replace the min and max with what you want and put the name of your float in the first part

[frosty hound]

https://docs.unity3d.com/ScriptReference/Random.Range.html

You can look at the docs for an example

[lost basin]

I'm currently watching one, and I tried replacing the code with his from GitHub but It still doesn't seem to work. I'm also not too sure what script needs to change, and I have a few

[mint remnant]

He has 2 different things going on at once, one is the plane at editor time the other is the mesh at runtime. So which one isn't working for you?

[lost basin]

The mesh isn't working, Like in the video it's just black, even in the editor, until I click on generate, change the DrawMode, or Turn a bool off and on again.

[mint remnant]

So the plane he uses is intended to just be for the development process to see the noise adjustments, that's why he wanted it editable in the edit mode, for fast changes. The mesh you eventually can't go on adjusting at runtime, gets too complicated., but it should render when you hit play at least

[lost basin]

It should, but it don't. What script fo you think might be causing this? The MapDisplay?

[frank flare]

what is iterator in C#? idk what this word means

@cosmic quail google doesn't help

it just says something like

"iterator method"

but it doesn't say what's iterator

[cosmic quail]

did you try googling "what is iterator in C#" and opening the first result?

[frank flare]

site doesn't open and words are hard

description doesn't really say much what makes sense

is GameObject iterator?

[cosmic quail]

maybe look at the other results then, this site seems to give explanations and examples https://www.alanzucconi.com/2017/01/22/iterators-c-yield-ienumerable-ienumerator/

[cosmic quail]

is that a coroutine?

[frank flare]

this

[cosmic quail]

should have posted this in the first place rather than asking what iterators are

[frank flare]

I'm trying to make GameObject spawnedObject; still keep the spawnedObject = Instantiate(itemToSpawn, Items.transform);

[short hazel]

"coroutines" use the C# iterator feature yes. You cannot use in, out, or ref with them

[cosmic quail]

why do you have a void inside a method

[frank flare]

I was messing with it

using ref in coroutine isn't possible and I should just do it like that?

[short hazel]

That will not work as intended, re-assigning the variable inside a method won't update the variable outside that method, unless ref is used, which isn't possible here

Why do you need the instantiated object outside the method?

[frank flare]

void Update()
    {
        if (Input.GetKeyUp("h") && Time.time - lastSpawnTime > 4)
        {
            Debug.Log("Key was just pressed");
            lastSpawnTime = Time.time;

            GameObject spawnedObject;

            IEnumerator SpawnItem()
            {
                GameObject sigma;
                for (int i = 0; i < 3; i += 1)
                {
                    sigma = Instantiate(itemToSpawn, Items.transform);
                    sigma.transform.position = spawner.transform.position;
                    spawnedObject = sigma;
                    yield return new WaitForSeconds(.5f);
                }
            }
            
            if (itemToSpawn.name != "Shit")
            {

                spawnedObject.transform.position = spawner.transform.position;
                //Vector3 direction = spawner.transform.position - (spawner.transform.position - spawnedObject.transform.position) * 800f;
                //Debug.Log(spawner.transform.position - direction);
                float randomX = Random.Range(-10f, 10f) / 10f;
                float randomZ = Random.Range(-10f, 10f) / 10f;
                spawnedObject.GetComponent<Rigidbody>().AddForce(new Vector3(randomX, -4, randomZ), ForceMode.Impulse);
            }
            else if (itemToSpawn.name == "Shit")
            {
                IEnumerator SpawnItem()
                {
                    for (int i = 0; i < 3; i += 1)
                    {
                        spawnedObject = Instantiate(itemToSpawn, Items.transform);
                        spawnedObject.transform.position = spawner.transform.position;
                        yield return new WaitForSeconds(.5f);
                    }
                }
                StartCoroutine(SpawnItem());
            }
                
        }
    }

because there's also other part

oh

I read it wrong

[frank flare]

because I don't want to have the spawnedObject.GetComponent<Rigidbody>().AddForce(new Vector3(randomX, -4, randomZ), ForceMode.Impulse); part inside the function

[short hazel]

Why not?

[frank flare]

I don't know but it just seems to be more customizable

[short hazel]

Nope, you can take the the if statements inside the coroutine instead, that will do the same thing.
Just make it so the yield instruction is still the last one within the loop, or else it'll add force with a 0.5 second delay.
Alternatively the part that adds force could be another script attached directly onto the prefab you Instantiate

[frank flare]

wdym Just make it so the yield instruction is still the last one within the loop, or else it'll add force with a 0.5 second delay?

[midnight meteor]

Hello , how can i make it returns random numbers like 0.3 0.4124 0.921314 ? it only returns 1 or 0 although its float not int

[short hazel]

You Instantiate, do some stuff then yield. Put the rigidbody stuff before the yield or it'll execute later on

[cosmic quail]

make it 0f and 2f to turn them into floats

[short hazel]

These numbers are ints. If you need floats add an f at the end of the number to instruct C# that they are to be interpreted as floats: (0f, 2f)

[frank flare]

why it will execute later on?

[short hazel]

Because you tell it to do so by using yield return new WaitForSeconds(0.5f)
Wait for 0.5 seconds at this point

[frank flare]

ah yes

[short hazel]

You need to understand the code you are writing/copying

[midnight meteor]

@short hazel oh i see thank you !

didnt think to do that

im not even sure what happened because i dont remember changing anything but now my entire movement script is failing

https://hastebin.com/share/mewotuyeva.csharp

and it keeps giving me this message that scalar calculations are faster than vector calculations for 40 and 41. i thought i had a grasp on it but ig not

i noticed something was wrong when the character couldnt really move, and originally i thought the problem was specifically the WASD function of the script, but not even the gravity works now

so the entire script is the problem, but the script is active on the player object

it was working yesterday and now its just

[languid spire]

why have you made no attempt to debug?

[marble hemlock]

it hasnt given me any errors

actually

sorry the script itself didnt give me any errors, but it kept saying that it was missing a reference

[languid spire]

Debugging is not about fixing errors, it's about seeing what your code actually does

[languid spire]

then it cant find your CharacterController

[marble hemlock]

that was an error on a button thing but im not sure its related

maybe its not the movement script thats the problem?

[languid spire]

if you debugged it like I said, you would know

[marble hemlock]

i mean i dont see anything that feels unusual

[languid spire]

I see one problem straight away, your usage of deltaTime

[summer stump]

You should definitely add debug.logs all over. See what executes and what doesn't. See if the values are what you expect at the moment of execution

[languid spire]

Oh, you're so experienced you can debug code by 'feel' ?

[marble hemlock]

nothing particularly stands out, i mean
i will try the debug.logs to see whats not turning on

oh i think i kind of have an idea

its not being used

sprint is giving a return but i must have removed the lines actually applying gravity and allowing movement

might just start the project over i think its just falling apart at this point

oh im fucking dense
the solution to the problem was right below the problem and i deleted the

okay got it up and running again 👍

[drowsy flare]

Anyone have a tutorial or general concept about an inventory system, where i can find items with attributes (ie "handgun", storyitem") and get their prefab?

[mint remnant]

there's only like 4-5 pages on google for the topic

[winter tinsel]

how can i lock the Z pos on an image ?

[mint remnant]

how is it being modified currently?

[north mesa]

chatgpt 🤷
(i was kidding)

[eternal needle]

Store it in a list or dictionary of enum to prefab

[winter tinsel]

is this a question for me or for the guy above?

[drowsy flare]

I currently store them in a list, but am not really sure how to handle the search for the correct item type. Got any ideas?

[mint remnant]

no was for you

[cosmic dagger]

from the context, this is a response for you . . .

[winter tinsel]

okay uh let me go check real quick

its being modified via transform and being set to the input.mouseposition

[mint remnant]

well the simple answer is mask off the z component so you don't move it in that dir

[winter tinsel]

okay what is masking

[mint remnant]

subtracting it from the vextor3, hidng it from the next calc

as it implies, to mask is to hide

[winter tinsel]

do i do this in the transform.position = input.mouseposition?

[mint remnant]

you could on the fly creat a new vector3 and for hte x and y parts pass them along, for the z part just put in 0

[rich adder]

this wouldn't work on world objects

[mint remnant]

difficult to know for sure without your code

[winter tinsel]

thats kinda all the code

[rich adder]

mousePosition is a screen coordinate / pixel position

[winter tinsel]

what happens is it modifies the z value and then

it becomes invisible ?

[rich adder]

oh if its UI its fine . and input mouse position doesn't have a z pos

[mint remnant]

so yea just force z part to 0 always

[winter tinsel]

then why does the Z value get sent to mars?

[rich adder]

it's not mouseposition at least

https://docs.unity3d.com/ScriptReference/Input-mousePosition.html

[winter tinsel]

idle, if i try to drag it the z value gets sent to mars and when i let go everythings okay again

[rich adder]

The z component of the Vector3 is always 0.

[winter tinsel]

the only thing here that when removed lets me drag it

BUT it doesnt make it snap back into place

is the

[pallid nymph]

=> mars is at z=0

[winter tinsel]

transform.Setparent(transform.root)

[rich adder]

setting parent is what's messing up the z prob

maybe you want to pass true to KeepsWorldPos argument

[winter tinsel]

see thats the thing

in the tutorial im following all of this works right?

and im supposed to add

transform.SetAsLastChild();

[rocky canyon]

it probably wouldnt be a published tutorial if it doesnt work

[winter tinsel]

that makes it viible and on the top

of the hierarchy

[rich adder]

ohh could you link tutorial

[winter tinsel]

issue is that doesnt work

it doesnt make it visible

here https://youtu.be/kWRyZ3hb1Vc?si=Yul-V9lgmRiRdd80

[mint remnant]

9 times out of 10 you missed some minor detail in hte turtorial

[winter tinsel]

i really dont think so this time

i like the guy cause he explains what the code does

and form that i can see that i really do have everything, not 1:1 but its correct enough to work

[rich adder]

tbh I dont even know whats going on in this image

is this what ur trying to do or

[mint remnant]

where in your code do you do the line transform.SetLastSibling??

[winter tinsel]

no dude the issue is the item DISSAPEARS 😭

[winter tinsel]

even if i put it in same issue

[rich adder]

when you drag or when you end drag?

[winter tinsel]

while dragging

in the idle position

when not dragged and after dragged

it snaps back to where it should be right

but while dragging it just

dissapears?

[winter tinsel]

look at these 2

its.... there? but its not showing up

[rich adder]

looks like its outside the canvas maybe ?

[winter tinsel]

yeah uh for some reason

[rich adder]

show a screenshot of the inspector while you dragging it with hierarchy visible

[rocky canyon]

^ this plz

[winter tinsel]

wait lemme debug something

okay so yes it does leave canvas right

and i know now what code makes it do that

parentAfterDrag = transform.parent;
transform.SetParent(parentAfterDrag);

i dont know why

what happens

where it suspposed to be

it goes and becomes a part of the player?, which is at the top of the hierarchy ig

even his does that

yet it simply dissapears

if i remove all the code except transform.pos = input.mousepos then i can drag it fine but it wont snap into place when i let go

the code that controlls that is also the code that breaks everything...

the point of transform.SetAsLastChild is to counteract this, and make it visible but it doesnt do the job right

[bleak sleet]

Can someone help pls, I want that for int value I delete 1 Tkey

[mint remnant]

that's a strange group by predicate there

[bleak sleet]

what=?

[languid spire]

that code is mostly nonsense, please post it correctly for help

[bleak sleet]

how should I post it correctly i dont get it

[rich adder]

instead of using Transform.root why not assign the proper transform so you know for sure its using the canvas..

root is going to go to the top most object

[polar acorn]

What the hell is this even trying to do

[mint remnant]

my thoughts exactly

[winter tinsel]

is that comparing a variable to itself?

[bleak sleet]

idk how groups work

[mint remnant]

apparently

[polar acorn]

What are you trying to use groups for at all

What is this supposed to accomplish

[bleak sleet]

im trying to find out how many of a specific TKey are in the Dictionary

[winter tinsel]

transform.parent instead of root?

[bleak sleet]

idk how to do it otherwise

[languid spire]

there can be only one

[polar acorn]

The answer is 1

[rich adder]

no make a proper field you can assign

[polar acorn]

A dictionary can only have one of each key

so the answer of "how many of this TKey are in the dictionary" is either 0 or 1

[bleak sleet]

Then i mean list

[rich adder]

what are you trying to do? what is the mechanic? what is this for ? etc..

[polar acorn]

So is it a list, or is it a dictionary?

[bleak sleet]

it has multiple values of the same so its a list?

[polar acorn]

How about instead of guessing, you just look at the code and check

[mint remnant]

What's TKey?

[rich adder]

the type for Dict

[bleak sleet]

it says dictionary

[rich adder]

but doesnt doesnt look like a dictionary

[languid spire]

TKey is the generic name for the type a key of a dictionary

[winter tinsel]

okay, well ill try that next but i changed it to transform.parent and magically, it wont snap into place

[willow scroll]

This is a more advanced way of writing ItemCount += intentoryList.Length;. #archived-code-advanced

[polar acorn]

Dictionary of what to what and which are you looking for

[bleak sleet]

bro what

[polar acorn]

A dictionary of what, to what, and which of the two are you looking for?

[winter tinsel]

hes asking you to explain the dictionary

[rich adder]

if its a dictionary why did you screenshot inspector of an array/list

[winter tinsel]

its a dictionary for what, goes to where and which one of the 2 elements are you looking for?

[polar acorn]

Dictionary<Foo, Bar> is referred to as a "Dictionary of Foo to Bar"

[bleak sleet]

ItemType Gameobject

[polar acorn]

Okay, so, Dictionary<ItemType, GameObject>. So, it maps an ItemType to a specific GameObject. What are you trying to actually do with this information right now?

[rich adder]

idk what that means, so is it still broken or

[winter tinsel]

point is, if i change it the snap-to function wont work, ie snapping to where it supposed to be after i let go

like a inventory yk

[bleak sleet]

Im just trying to see how many of a given Itemtype are in this dictionary and then removing it for (value) times

[rich adder]

youu mean the parent after or before drag?

[winter tinsel]

first, to get rid of confusion its not an ACTUAL function in the code

[polar acorn]

Dictionary<ItemType, GameObject> can have exactly 0 or 1 of a given ItemType

[winter tinsel]

on drag start, if i change from transform.root to anything else it wont snap to where its supposed to after i let go

whats putting it where its supposed to go is a grid component

[rich adder]

which is where? havent shown the hirerchy while dragging

[bleak sleet]

then Im just trying to see how many of a given Gameobject are in this dictionary and then removing it for (value) timess

[winter tinsel]

i have

[winter tinsel]

here

while dragging it goes to the root, ie the player

[rich adder]

which one is the canvas? there is no label

[winter tinsel]

canvases areee let me check

[polar acorn]

Getting the count is easy, but if you find them, which ones do you want to remove? If the same object is in there under let's say five keys, and you want to remove four copies of that game object, how do you intend to know which key-value pair to keep?

[marble hemlock]

uh i got an error but this time i actually didnt do anything

[winter tinsel]

the gameobject named iteminventory is the canvas

[marble hemlock]

its not an error in VS but in unity's console

[rich adder]

and what is a canvas named iteminventory is beyond me..

[ruby python]

Hi all, I'm hoping someone can help with a little bit of code I'm having trouble with.

  newRecipeItemAvailable.text = 
    GameManager.gameManagerInstance.stationResourcesManager.availableComponentList
    [newBuildableItemRecipe.dataContainer.stationModuleRecipeList[i].componentAvailableIndex].componentAmount.ToString();

Full Code here
https://hastebin.com/share/gebafinuti.csharp

It's a little bit messy/simple at the moment.

Basically I have two lists of Classes (AvailableComponentList which keeps track of how many components the player has 'in Stock' (First Image) The Entries in this list are of the Class 'AvailableComponents'. This lives on my StationResourceManager script which is 'attached' to my GameManager.

public class AvailableComponents
{
    public string componentName;
    public int componentAmount;
}

and a 'StationModuleRecipeList' in which the entries are of the 'StationConstructionRecipe' Class which lives on the Scriptable Object for the specific module the player wants to build.

public class StationConstructionRecipe
{
    public string componentName;
    public int componentAmount;
    public int componentAvailableIndex;
}

I'm using the 'componentAvailableIndex' int to reference the specific Resource Manager list entry to then run a check to see if the player has enough of that resource to build the Module.

The problem I'm having lies in the line of code I've posted inline above. Everything up until that point works great, but it's seemingly not finding the 'componentAmount' list entry. So, would anyone be able to see any errors/issues in terms of finding said value in the way that I've written it above? Been staring at it for a while and just can't see an issue.

[bleak sleet]

you aint really helping here thanks

[winter tinsel]

huh?

im naming it for organising

[rich adder]

"InventoryCanvas" would make more sense to me..

[polar acorn]

I am literally answering exactly the questions you are asking

If these don't help, ask better questions

[winter tinsel]

lets not get stuck on naming semantics

[bleak sleet]

you are literally asking me question, I came here to get normal answers

[marble hemlock]

so it said "hey you dont have tmp pro stuff so we're going to import it" and it did
and its working, but now at line 525 its giving an error in the unity console that the object reference not set to an instance of the object

[rich adder]

naming is important to identify whats what... Anyway looks like when you do root it goes to Player

[marble hemlock]

i just wanted to show the full page cuz its not my script

it just appeared with an error?

[polar acorn]

Because you seem to have absolutely no idea what you even want to do. Your question of "how do I know how many of a key are in a dictionary" was answered. It's 1. If the key is in the dictionary at all, it's 1.

[winter tinsel]

yeah, and the player is uh, not a canvas lol

should i just make it a canvas?

[languid spire]

there are 3 things on that line that could be null, find out which

[marble hemlock]

uh nvm
i delete the error and it doesnt seem to come back up

[winter tinsel]

or disconnect the whole Inventorycanvas thing from the player?

[bleak sleet]

Then u just lack knowledge and cant seem to understand my questions right

[winter tinsel]

cause i put it in thinking i need it to be a child of the player or it wont work right but since its just ui over the full screen then i dont think it needs to be a child

[rich adder]

if you can't explain your problem clearly , you wont be able to solve it

[marble hemlock]

i hope it doesnt come back to bite me

[ruby python]

Digi really doesn't lack, and tbh that attitude ain't going to get you any help.

[rich adder]

noo , instead of using things that depend too much ion hierarchy order. Dont use things like transform.root or tranform.parent unless you're absolutely know for sure who the parent is etc

[polar acorn]

I have literally been answering questions here for half a decade and you don't know whether you are using a dictionary or a list

[winter tinsel]

okay i fixed it

i just removed it and made the whole inventory its own parent

[polar acorn]

So maybe get your shit together and figure out what you even want to happen. If you literally do not even know what you want how can you expect me to tell you how to do it

[rich adder]

I mean..you could've just made a field for Transform..but whatever floats your boat lol

[marble hemlock]

is there a way to have a button have an outline

[winter tinsel]

the boat is floaty

[marble hemlock]

trying to link up this button to

[rich adder]

yes but this isn't a coding question now is it..

[winter tinsel]

and im a capitan thatll sail till i crash

[marble hemlock]

true

[bleak sleet]

this guy was giving me attitude first fr, attacking a newbie over very nice

[rich adder]

"I am the captain now"

[winter tinsel]

sorry but the jack sparrow doesnt negotiate

with somali pirates

its kaptaejn but he pronounces it kapitan

[rich adder]

asking you to clarify your question isn't an attitude.

[languid spire]

you should know better than that

[rich adder]

oh shit you right let me delete that. forgot where i was for a second 😛

[polar acorn]

I am literally the only person who was attempting to make sense of your nonsense scribblings of garbage code enough to help you while everyone else just assumed you were too far gone to help. I guess they were right on that front.

Have fun never making your game and generally continuing to fail at everything you attempt to do. I'm done.

[bleak sleet]

oh nice very nice thanks for your very kind words!

[winter tinsel]

hes right tho

as a newbie we uh, we suck at coding lol so listen to what he says

but i do agree that he can come off as agressive in the way he talks

[languid spire]

I was still waiting for him to post his code correctly, which, apparently, was too much to ask

[bleak sleet]

idk man am new around here, and I think i have both a list and a dictionary thats what caused confusion

[winter tinsel]

what caused confusion is that you didnt really explain exactly what you want

not with the code, but in general

what is the idea you are trying to execute yk

[polar acorn]

Nah, apparently asking for clarification is an "attack"

[winter tinsel]

nono you just have a agressive way of speaking i kinda agree with him on that

[slender nymph]

if you are not sure, then post the full code so someone who knows how to read the code can determine which you are using

[winter tinsel]

That being SAID, still he didnt give correct clarity

[winter tinsel]

so lets start here

[ruby python]

tbh, I don't think Digi is aggressive at all, just right to the point without any dicking about. lol.

[winter tinsel]

what is your idea @bleak sleet ?

[rich adder]

tbh the time i been here its pretty rare see digi being a bit more stern , its usually the other person being furstrating tbh>
Can sympathize, helping someone who wont try to help themselves gets frustrating..

[winter tinsel]

yeah and some people understand directness as agressive

i say that as someone who is extremely direct, so its better to dilute the directness because otherwise it can come off as agressive

even though it might not really be, people can understand it in that way

[rich adder]

there is community rules about "perceived" tone

don't assume, its text after all..

[ruby python]

Clear explanations go a loooong way to getting useful help. That's why my questions tend to be on the long side, as much detail as possible about what you want to do and what the issue is. lol.

The most common 'useless' request for help is "why is this broken?" lol.

[rich adder]

I get called the "aggressive" or "with attitude" 90% of the time here

[eternal needle]

Sorry got busy at work. Dont know if anyone else replied
You either store them in lists specific to each item, which could be done by a dictionary, or loop through the list and just check. I'd store them in a dictionary of enum to list of prefab

[rich adder]

apparently being direct is aggression on these new Zboyz

[winter tinsel]

yea, but as a newbie, from my perspective im a dumb dumb and youre the masterclass superteacher who knows everything so i dont have to explain it

[winter tinsel]

Zboyz lol

[bleak sleet]

Im trying to do crafting table and want to do it variable so that in future I can easily make something take 2 of specific Items but I have no idea how to check if theres those items inside and how to remove them properly. I keep getting error messages

[rich adder]

perhaps you should learn the tools you are attempting to use before you use them..

[winter tinsel]

better

[bleak sleet]

yes maybe... learning by doing...

[frosty hound]

It would help to share the errors?

[rocky canyon]

seems easy.. create an Item.cs and hold a list/array of Items

[rich adder]

yes but also searching things you dont know.
How do dictionaries work and such..

You can get frustrated when your question doesnt make sense..

[bleak sleet]

its ok im gona try later by myself gtg w dog now

[winter tinsel]

furtstaed lol

looks like a german city name

furtstadt

[marble hemlock]

can you have a child object with a script tell its parent to no longer be active or can i only work downwards

[drowsy flare]

I got it working with a list of scriptable objects with keywords and reference to the prefab. Thanks for the support, the message kind of got drowned in stupid replies like "google it"

[winter tinsel]

i and i think we suggest to actually not do that and look up how a crafting grid system is best implemented

[rocky canyon]

ya, once

[rich adder]

haha yeah I havent had my matcha yet 🍵

[ruby python]

Yeah, this is where a lot of people fall over. Never assume anything. Especially being newbies (I still am too, but learning slowly. lol.), the code could be so very very wrong it would have no chance of actually doing what you want it to do, so even the best coder in the world wouldn't be able to just look at it and figure it out.

[winter tinsel]

doing it yourself will just get you furtstadt

[rich adder]

its good to do it yourself if you plan on researching as you go
its not good if you expect to know it all out of gate.

[winter tinsel]

thats the point, this is what we think as newbies, that youre allknowledgeale on the topic yk

we

literally think, that youre tech wizards

[rocky canyon]

the thing i see most w/ newbies is "my code should be doing this.. but it does this instead"
... sir, it does the exact thing you told it to do

but that fixes itself w/ time

[ruby python]

Yeah, that was my point in my previous comment. 🙂

[marble hemlock]

idk if this is overcomplicating it but im going to try to attach separate scripts to specific buttons (one will turn off the parent object), and then have the player have a script that allows them to turn it on/off.

idk if it'll work but i'll find out ig

[rich adder]

I wish..half the time they skip the "whats supposed to happen instead" bit
"my script no work"

[rocky canyon]

as long as ur only turning it off (once it is disabled the script /child will not be able to turn on its parent (itself practically)

[winter tinsel]

i had my own moment with this

[rocky canyon]

we all do..

[winter tinsel]

tried to put 2 contradicting if statements

[ruby python]

Yep, the good old "Why is this broken?" question. lol.

[winter tinsel]

why is the code that wont work unless a nuke ray from a supernova explosion touches the one bit and changes it to 1...... not working?

[rich adder]

lol shows screenshot of random scene stuff "Why is it doing this?"

[rocky canyon]

my first problem w/ that was
id' set something in the if statement. and then immediately check in teh else if it was not ..
then ur basically running a useless if statement

if makes thing false.. else runs regardless lol

[ruby python]

LMAO. And then screenshot the code. When I first came on here, didn't bother me cause I didn't know enough to offer advice/answers, but now it really winds me up. lol.

[marble hemlock]

oh i just realized im working out of order

i was trying to set up the buttons to work but i cant even test if the buttons work because i havent set it up to allow the mouse to freely move

[rocky canyon]

if (isActive)
{
    isActive = false; // This sets 'isActive' to false
}
else if (!isActive)
{
    Debug.Log("isActive is false now!"); // This will always run because 'isActive' was just set to false
}```

[rich adder]

isnt that without the else if but just another if

or did i brain farted

[rocky canyon]

i think an else would actually work?

idk im still drinking my first cup of coffee ☕ ¯_(ツ)_/¯

[rich adder]

i think of else if like a switch case

if the first one was hit, the rest dont evaluate no?

[rocky canyon]

• if statement: Checks the condition. If true, the code block executes, and then it skips the rest.
• else if statement: Only checked if the previous if (or else if) was false. If true, its block executes, and the rest are skipped.
• else statement: Executes only if none of the above conditions are true.

[languid spire]

that code is nonsense, shame on you

[marble hemlock]

is it bad practice to attach debug.log to a bunch of stuff to constantly keep seeing if its registering things

even if nothing is broken yet

[ruby python]

No, it's very good practice.

[marble hemlock]

noted
thank you 👍

[languid snow]

yo how do i store functions inside a list

[languid snow]

wait nvm i asked chat gpt

[rocky canyon]

cool.. i been looking for a good c# compiler just for fun

[languid spire]

List<System.Action>

[rich adder]

List<Func>

[languid snow]

do both work

[rocky canyon]

i us System.Action

[rich adder]

yeah action is simpler though (method has no return)

[languid snow]

alr

[languid spire]

depends on your method signature

[ruby python]

Code screenshot? tsk tsk. lol. (j/k :-P)

[rich adder]

I was mainly showing the Console log but yea

[languid snow]

chat gpt said this

chatgpt is a fraud., ty guys

[ruby python]

Yeah I know, just couldn't resist. lol.

[rich adder]

Func is for methods that return value, Action is fine if its a void

[rocky canyon]

       private void DrawCenteredButton(string buttonName, System.Action onClick)
        {
            GUILayout.BeginHorizontal();
            GUILayout.FlexibleSpace();

            // Draw button with custom style
            if (GUILayout.Button(buttonName, buttonStyle))
            {
                onClick?.Invoke();
            }

            GUILayout.FlexibleSpace();
            GUILayout.EndHorizontal();
        }``` attribute button

[rich adder]

I use also an Action as method param to a IEnumerator
a nice modular way to make many timers for diff methods/actions

[rocky canyon]

i remember when i was very new.. i asked if i could pass a method into another method.. and someone called me stoopid..

said c# wasn't a macro language 😐

[rocky canyon]

you'll be better off in life if you question everything that thing tells you

[languid spire]

best useage for passing a method into a method is for async or coroutines to get a callback on completion

[rocky canyon]

that'd be great for my loading system

[rich adder]

very handy indeed

[ruby python]

Yeah, it does crack me up that it really struggles with arrays. It has no idea how to count indeces. lol.

[languid snow]

yeah, but for very basic stuff it helps

[rocky canyon]

whats horrible is it gets totally stuck when u go deep enough

[rich adder]

 private IEnumerator CoolRepeatingTimer(float timeUntilSomething, Action method)
 {
     while (true)
     {
         var time = 0f;
         while (time < timeUntilSomething)
         {
             yield return null;
             time += Time.deltaTime;

         }
         method?.Invoke();
         yield return null;
     }
 }```

ops

[rocky canyon]

not saying it doesn't.. just never take what it says as concrete facts

i use it quite a bit to make tedious things abit less tedious

[ruby python]

tbh I use it occasionally just to get it to type out code that I'm feeling too lazy at the time to type myself. lol.

[rocky canyon]

for example.. giving it a list of enums and having it vomit out a switch statement for me

[ruby python]

I know enough now that I can spot whether it's wrong or not.

[rocky canyon]

or atleast get a feeling its going off the deep end 😅

[ruby python]

lol.

[rich adder]

yes if you can't spot whats wrong it can lead you into very dark places lol

[languid spire]

That is horrible, should be an array of Action and use the enum as the index

[rich adder]

I mean if it works it works amirite

[languid spire]

no

have some pride in your work

[rich adder]

I was studying the C++ code for GTA3 repo yesterday and their Enemy AI is basically one giant switch lol

[ruby python]

It's 'knowledge' is very out of date too. I asked it once (gpt3.5) how up to date its Unity c# knowledge was and it was something like 2017.

[rocky canyon]

  IEnumerator BootEnvironments()
    {
        FindLightController();
        yield return GetRandomWaitTime();
        environmentProgress = 100f;
        IncrementSector();
    }

    IEnumerator BootSystems()
    {
        FindGamePlayObjects();
        SetupSettings();
        yield return GetRandomWaitTime();
        systemsProgress = 100f;
        IncrementSector();
    }

    IEnumerator BootGameSetup()
    {
        SetupPlayer();
        yield return GetRandomWaitTime();
        gameSetupProgress = 100f;
        IncrementSector();
    }

    IEnumerator BootVisualFX()
    {
        FindCanvasObjects();
        yield return GetRandomWaitTime();
        visualFXProgress = 100f;
        IncrementSector();
    }``` guess i could make this *functional* now 😄

[rocky canyon]

@languid spire 👆 horrible v2

tbh its due for a refactor.. this codebase is going on 2 years old..

soo past me thought it was legit 🤣

[rich adder]

I always evaluate
Time spent refactoring vs time spent rewriting it from scratch

[languid spire]

This is a typical example of making code up as you go along instead of actually designing it first and then writing it

[rocky canyon]

umm wtf?

[ruby python]

Sorry, not sorry for bumping this. lol. I know it's a lot to look at, but any ideas? lol.

[rich adder]

70% of my code 😢

[pallid nymph]

design first is not realistic, so you're good 😛

[rich adder]

Im horrible at designs and graphs

[rocky canyon]

ya, i wasn't skilled enough to design it first.. and then build it..
my workflow consisted of.. building up a little at a time..
then having a guide I could actually conceptualize..
then rebuilding it basically from scratch

[rich adder]

luckily I'm more of a generalist than a "coder" so to me as long a it works and its clear intent is there, I dont bother unless there is a performance issue

[languid spire]

design first is 100% requiered if you want to produce good code

[rocky canyon]

steve had c# grow up along side him.. its easier for him 😈

[pallid nymph]

design first, but to some degree, sure... I've seen so many people (and I've done that too) spend week on design, and all that fails a little after you actually start writing code and using it

[languid spire]

this is not a C# thing, it's a professional programmer thing

[rich adder]

either that or you somehow did not foresee something unexpected while developing it

[pallid nymph]

I tend to reach good code much quicker if I have only a high-level design plan and then write code that mostly does it and iterate

[ruby python]

I have a bad habit of coming up with new ideas for the thing while I'm writing/building it. lol.

[rich adder]

yeah I dont mind constantly iterating over it as long as I have a general idea/concept in mind already

[rocky canyon]

same.. i keep scratch pad/paper next to my desk.. when that happens i just jot it down.. and try to move forward.. w/o dwelling on it too much

[languid spire]

nothing is carved in stone but it's a damn sight easier and quicker to tweak a design than it is to refactor a complete code base

[pallid nymph]

sure, but the design misses various details, also if it takes a long time to produce the design, you could be weeks in without doing any of the... practical work

whereas if you do high-level design, write some code that does some of it, then iterate, you kinda balance these... gives you an option to finish early, if some priorities changed

[rich adder]

haha fresh out of college CS students

[languid spire]

and saves yourself many more weeks documenting the spaghetti you produced

[rich adder]

too much yap less practice/exp

[vast vessel]

hey guys.
is there a way for me to get a list of all types derived from a base type (in this case, Action_Node)
and then use them as a list of type Action_Node, instead of a list of type Type?

i cant simply convert them with the as keyword. so are there any other ways to do this?

[pallid nymph]

I don't produce spaghetti 🤷‍♂️

[languid spire]

if you dont design, believe me, you produce spaghetti

[rocky canyon]

c#sharpghetti 🍜

[polar acorn]

What is the specific error you're getting on this

[pallid nymph]

I do design, just do it as an iterative process of refinement, and of coruse even the initial one is not 🤢 unless I need to potentially finish a new feature in a day

[pallid nymph]

some people get carried away with 20 days of design and only then code... that's what I'm against

[polar acorn]

Can you show the code for CreateNode?

It looks like this function takes an Action_Node, not a type

[vast vessel]

void CreateNode(Node node) {
        var n = graph.CreateNode(node);
        node.name = n.GetType().Name.Replace('_', ' ');
        CreateNodeView(node);
    }```

[polar acorn]

Yeah, looks like it takes an instance of Node

A type is not an instance

[vast vessel]

oh youre right

[umbral rock]

trying to make an AI enemy controller but i get a weird error like this

[ruby python]

Try moving your 'agent' gameobject up a little (above the navmesh surface)

[umbral rock]

i need to place him extremely high then... and then i get error failed to create agent because there is no valid navmesh

[ruby python]

Not really sure what you mean tbh. Basically your enemy (with the agent component) essentially raycasts down from the bottom of the collider to 'find' the navmesh, so if it's too low it can't see the navmesh, hence the first error. (that's a simplistic explanation and the best I understand it)

Also, might be better in https://discordapp.com/channels/489222168727519232/763502536354168882

[languid spire]

what is 'weird' about the error? What dont you understand about it?

[umbral rock]

wait, what should the navmesh be? the ground?

[ruby python]

Whatever the enemy walks/moves on.

[polar acorn]

Why is "just above the navmesh" mean "exteremly high"?

It should just be up enough to know for sure its collider isn't intersecting the floor

[ruby python]

Yeah that confused me tbh.

[vast vessel]

is this a good way of creating a new instance of a type, that will always be derived from typeof(Node), and then converting it to a Node?

this is how im using the method :

[polar acorn]

Well, if the thing you're creating is a child class of Node, all instances will be of type Node. I have no idea what the point of all this reflection is, but it looks like Node might be a ScriptableObject. Wouldn't it be easier to just manually create a few instances and load them from Resources or something?

[vast vessel]

its not a scriptable object.
node itself derives from nothing

its as base as you can get

[polar acorn]

Okay, so, you can create one via new just fine. I'm guessing there's a lot of sub-classes that extend Node?

[vast vessel]

i need to get all types deriving from Node, then create a new instance of those types, no matter what they are, then use them as a Node.
thats why im doing all of the convertions.

[vast vessel]

how can i just use new?

[umbral rock]

well its weird, i'v put the navmesh (the ground) into the navmesh variable of the enemy and i still get the error look..

and the code

[polar acorn]

For example, new Action_Node()

[polar acorn]

Your NavMeshAgent is disabled

[vast vessel]

its not garuenteed to be a actin node. it might be any type that derives from it.

im using this as a replacement graph.CreateNode((t)Activator.CreateInstance(type) as Node)

[polar acorn]

Okay, so, you just need one blank instance of each deriving type of Node then?

[vast vessel]

yes

[umbral rock]

indeed, but it stays the same if i enable it, i just disabled it to look what happens and forgot to turn it on again

[vast vessel]

[polar acorn]

So from the types, you want to get the constructor and invoke that method. It even lets you pass parameters to it if you have constructors that take them

https://stackoverflow.com/questions/3255697/using-c-sharp-reflection-to-call-a-constructor

Although that does seem to be what you're doing with CreateInstance as well, which I thought was ScriptableObjects (they also use CreateInstance to be instantiated)

[vast vessel]

is this any better then the code i sent? it seems a bit longer.

[polar acorn]

So I think your code here could work, but I think the casting could be made simpler:
graph.CreateNode((t)Activator.CreateInstance(type)) should be enough

[polar acorn]

Yeah, I think I circled back to the same thing you were already doing after talking myself out of my own alternative

[vast vessel]

i need the as Node at the end:

[vast vessel]

alright, ty 👍

[polar acorn]

Actually, I think what you might need is to constrain the type parameter. You might need a where t : Node on the function declaration

[vast vessel]

okay ill add that too!

[winter tinsel]

how do i change where unity stores builds?

[rich adder]

which builds?

[winter tinsel]

when you do
"build and run"

where it stores the build

that it runs

[rich adder]

the file explorer?

[frosty hound]

Wherever you designated it to be when you first made the build

[winter tinsel]

can i change that?

i know where it is i wanna change where its saved

[frosty hound]

If you just do a normal build (not build and run), it should ask you where

[winter tinsel]

and then when i do build and run itll save it there right=?

[rich adder]

why not try it

I almost never do Build and Run , i simply save to folder I want and the folder automatically opens when its done. I just run the exe..

[winter tinsel]

allright thats it

i wouldnt have figured that out its not intuitive for me

[bleak sleet]

This is too ez

[steep rose]

What is

[bleak sleet]

idk I did it somehow

2 errors i had

and it works as i wanted it to

[hallow sun]

what's the name of the boolean function that goes like this: var = bool ? a : b

trying to google if it works with enums

[rich adder]

ternary operator

[wintry quarry]

Wdym by "works with enums"?

It works with any expression that returns a bool

[rustic wasp]

do you mean

enumyouchoose==wantedenum kind of thing

== expression returns a bool

it would work with anything that returns a bool

[thick rivet]

Yall im watching a video and I'm following the script the first line he put worked but the second one doesent and when i type the popups dont come up this is the script https://gdl.space/hokiquwazo.http

[polar acorn]

And what does the tutorial's code for that line look like?

[wintry quarry]

You need to configure your IDE

!ide

[eternal falcon]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• Other/None

[wintry quarry]

Then the "pop-ups" will appear

And you will make fewer typing mistakes like this one

[thick rivet]

I can send A pic of it

[thick rivet]

It was working before tho

[frosty hound]

Your code has errors. So configuring your IDE will point it out.

[polar acorn]

Sure, go ahead

[thick rivet]

But why did it randomly stop working,m

[polar acorn]

"I did it exactly like the tutorial so why does theirs work and mine doesn't" counter:
Number of times it wasn't exactly like the tutorial: 175
Number of times it was exactly like the tutorial: 5
Number of times the code literally did not exist: 1
2022-07-19 to 2024-08-13

[frosty hound]

Because you typed it wrong

Code doesn't "randomly" change itself.

[rich adder]

called it

[thick rivet]

What did i type wrong then?

[rich adder]

this isn't the code you sent in the link

[pulsar forum]

You added a semicolon, also pls don't share code with just a picture from your phone

[terse spindle]

hey walleliu

[rich adder]

I think this is still the tutorial picture

[terse spindle]

Cannot modify the return value of 'Transform.position' because it is not a variable (CS1612)

[thick rivet]

This is mine

[thick rivet]

This tur

Tur

Tut

[frosty hound]

No, this was yours
#💻┃code-beginner message

[thick rivet]

He also put a semicolon but i wasnt able to sc it in time

[pulsar forum]

Transform.position = Transform.position.yz + xvalue * Vector3.right

[rich adder]

then why didn't you send the whole thing properly

[thick rivet]

I thought i did?

Sorry I'm just very confused 😅

[rich adder]

you sent 4 lines
3 of them whitespaces

you were meant to send the Entire script as you had it

[thick rivet]

Ohhhh

I didint know

[polar acorn]

Then why did your pastebin say otherwise

[hallow sun]

Does anyone have an idea why this:

    {
        RaycastHit2D hit = Physics2D.Raycast(transform.position, Vector2.zero, Mathf.Infinity, LayerMask.GetMask("UI"));
        if (hit.collider != null) hit.collider.transform.gameObject.GetComponent<Food_1>().GiveToppings(order);
        ReturnToHolder();
    }```
always trigger twice? its not an issue so far, but any debugs write twice, so it could be a problem when i add scores

[pulsar forum]

Wait sorry Vector3 doesn't have those vector operations, tform.position = new Vector3(xvalue, tform.y, tform.z)

[rich adder]

which code did you think we were referring to then ? Anyway send the actual script as you have it written

[polar acorn]

What calls Dropped

[thick rivet]

Idk whats a pastebin😭😭

[thick rivet]

Ok

[terse spindle]

letme try

[thick rivet]

I thought ylal were tlaking about the one line of code

[rich adder]

well its imprtant to see exactly how you wrote it, hence those paste your code and send link type of websites

also, is your script placed on a gameobject ?

[hallow sun]

when there is no mouse input, but still has the item reference:

// if input detected
else if (item != null)
{
    Drop();
    return;
}
void Drop()
{
    active = false;
    item.Dropped();
    item = null;
}```

[thick rivet]

yes

https://gdl.space/relotanaji.cpp

this is the script

[polar acorn]

So, Drop is likely getting called twice. What calls that

[polar acorn]

Okay, and what's the actual error

[steep rose]

I would just post your full code so we dont have to chase the scripts.

[dire tartan]

so im making a 2d game and i want it that if the character hits a wall its momentum is flipped i wanted to make empty gameobjects on both sides and if collided put a negative sign on the velocity is there a more efficient way of doing this?

[hallow sun]

drop is called by the else if, and that is simply on Update()

[thick rivet]

it doesent work in unity it says "Assets\Pipemovescript.cs(19,60): error CS0117: 'Vector3' does not contain a definition for 'Left'"

[steep rose]

Do right

But negate the vector

[polar acorn]

So check the tutorial

They didn't write Left

[rich adder]

if its not underlining that red inside your code editor, you need to configure your IDE was it was suggested
it wont fix the issue but will help you avoid these simple mistakes

[true wind]

Anyone that knows TextMeshPro can help me? I'm getting different results when calling a TypeWriter coroutine before and after a Canvas.ForceUpdateCanvases() and it's driving me crazy, idk what is wrong.

[thick rivet]

hmmm i change it then

how do i do that

        }
    }

    #endregion``

am I doing something wrong os is TMP being finicky?

[umbral rock]

anyone knows why i cant drag the TMP text into the variable?

[thick rivet]

now it says "The referenced script (Unknown) on this Behaviour is missing!"

[rich adder]

because its textmesh and you seem to have the UI one

[polar acorn]

Probably because you are trying to drag a TextMeshProUGUI into a TextMeshPro field or vice-versa. Your variable should be of the type TMP_Text to cover both cases

[true wind]

could you show your code? are you referencing a TMPro.TextMeshProUGUI element?

[polar acorn]

Do you have any other errors

[rich adder]

use links for large code

[thick rivet]

dont think so thats all it says in unity

you saved during playmode ?

[languid snow]

so i have a list of voids using list<system.action> called "rollMejoras" , and i wanna add one of those to a button onclick i thought this would work but it wont :(

[thick rivet]

no idea havent pressd play sense i first asked the question

[thick rivet]

console

[rich adder]

clear console and press play see if it comes up again

[languid snow]

the error says "The non-invokable member 'LogicManagerScript.rollMejoras' cannot be used as a method." (its translated from spanish so it might not be accurate)

[umbral rock]

TMP_Text doesnt work either

[rich adder]

what is the error saying ?

[rich adder]

it will

[true wind]

I would do as one answer suggested and use TMP_Text instead of TextMeshPro

[languid snow]

@rich adder here!

[polar acorn]

AddListener requires a function as a parameter. By calling rollMejoras with a parameter of 0, you are instead calling rollMejoras and passing the return value to AddListener

[thick rivet]

how do i make it so it doesent delete stuff in hierachy when i press play

[rich adder]

yes because thats not how you access element of array, use []brackets

[languid snow]

this doesnt change anything

[polar acorn]

It doesn't delete anything you don't specifically tell it to

[languid snow]

btw

nvm itr does change

but its another error

[rich adder]

mate lol () is for methods [] is for array/list

[languid snow]

Cannot convert from 'System.Action' to 'UnityEngine.Events.UnityAction'

[thick rivet]

how do i know if i told it delete sum

[polar acorn]

If you want the button to call rollMejoras(0), then you'll need to make a parameterless function that calls it. Either:

public void DoRollMejorasZero(){ rollMejoras(0) }

and then AddListener(DoRollMejorasZero)

Or you could one-line it:

AddListener(() => rollMejoras(0));

[umbral rock]

it doesnt lol, look

[polar acorn]

Did you call Destroy

[polar acorn]

Are you trying to reference a scene object on a prefab?

[thick rivet]

i dont recall doing that

[terse spindle]

I wanna make it like subway surfers like when you on the right you need twice input to go to left but in this code it takes one input to go to the left from the right

I want "right -> middle -> left"
it goes "right -> left"

show the Text object
