rb.velocity = new Vector2(Input.GetAxis("Horizontal"), Input.GetAxis("Vertical")) * moveSpeed * Time.deltaTime * 60;
So i made this top down movement line of code and noticed that it moves way too fast diagonally, I found on the documentation that to fix this i need to normalize it but when i add .normalized like in the following line it genuinely tweaks tf out idk how to explain. Any way I can normalize the vector without it having an aneurysm?
rb.velocity = new Vector2(Input.GetAxis("Horizontal"), Input.GetAxis("Vertical")).normalized * moveSpeed * Time.deltaTime * 60;

[static bay]

Well for one, you don't need to multiply it by Time.deltaTime.

rb.velocity handles that for you.

[flint heath]

oh

it still acts weird as though

[static bay]

Same with the 60, idk why you need to multiply it by some random number.

[flint heath]

if i remove both of those and its just ... .normalized * movespeed;

it still freaks out

[static bay]

yep

the freakout has to be from elsewhere, because that line looks fine

[flint heath]

idk theres not much else lmao

[static bay]

well how is it "freaking out"?

[flint heath]

the movement acts really weird when it's normalized, if i tap any movement key and immediately let go, it will keep going for an extra half second

and the movement is overall just super jerky and unresponsive

[static bay]

Oh I see.

[flint heath]

but is completely fine when not normalized

[static bay]

Do you know what normalizing does?

[flint heath]

im not exactly sure no

its like something to do with the radius of a circle around you or smth

[slender nymph]

this is due to using GetAxis which includes input smoothing. you want to use GetAxisRaw instead

[flint heath]

thank you :)

ill try it

[static bay]

I'm sure he wants a bit of smoothing. Issue is that normalize is setting it to 1 even when values are low.

[flint heath]

oh yea cos something about magnitude of 1

[flint heath]

yeah this worked, thank you :) I'll be able to add my own smoothing myself

[static bay]

Normalizing a vector refers to making its length 1. Normalized vectors are useful because they can represent directions.

[slender nymph]

if you want smoothing from GetAxis or to support analog movement with lower values, then clamp the magnitude of the input to 1 rather than just normalizing it

[static bay]

If you want to use the smoothing provided by Unity, you can use this with a value of 1.
https://docs.unity3d.com/ScriptReference/Vector2.ClampMagnitude.html

This will prevent the length of the vector from exceeding a value of 1.

So you won't speed up on diagonals.

[flint heath]

oh i see

[static bay]

Also, do you know why it's speeding up on the diagonal?

[flint heath]

yeah

because moving up 1 and to the side one

so 1.41 units

ish

[static bay]

Yep, exactly.

[flint heath]

wait how is clampmagnitude different from normalize?

[static bay]

Normalize forces the length to 1, this includes smaller values.

[slender nymph]

because it allows the magnitude to be lower than 1

[static bay]

ClampMagnitude "clamps" it to some specified value. Aka it will not exceed the value, but can be smaller.

[flint heath]

oh that makes sense

[static bay]

So what was happening was Unity trying to smooth out your value, slowly increasing it to 1 (full speed) as you held the button, and slowly decreasing it back to 0 after you let go.

Normalize forced all those smaller intermediate values back to 1.

And only gave 0 when the input was literally giving 0.

Which caused that "unresponsiveness".

[flint heath]

that actually makes a lot of sense

aight rate the new smoothing i added

not sure what the f means but i saw people typing it after numbers in videos in the past and so it wasnt working at first so i typed an f and it worked 🔥

[static bay]

It might be useful to check out some of the functions in Unity's Mathf and Vector classes structs. There's some exceedingly useful stuff in there. Specifically the Lerp, Clamp, Distance and MoveTowards functions.
https://docs.unity3d.com/ScriptReference/Mathf.html
https://docs.unity3d.com/ScriptReference/Vector2.html

[slender nymph]

based entirely on this statement, you should stop what you are doing and go through some beginner c# courses. there are some great beginner courses pinned in this channel

[flint heath]

that's probably a good idea

I've tried to search to understand some of the things I have seen in the past like the f that people sometimes type after numbers and what a vector is (point? line?) but honestly the unity documentation isn't very easy to understand

so yea some c# courses could be helpful

[static bay]

f marks the number as a float.

Do you know what a float is?

[flint heath]

non integer number?

[static bay]

Ya. It stands for a floating point number.

[flint heath]

from what ive gathered

[static bay]

It represents "real" numbers. Aka everything with decimal places.

[flint heath]

ok sick, why isnt every number always automatically parsed as a float then? why do we have to do it manually?

[static bay]

Vectors are more of a math concept. They're "lines" composed of a magnitude and a direction.

You can do an absolute shit ton with them.

[eternal needle]

there are more than just floats, sometimes you only want whole numbers. outside of unity, double is used a lot more as well.

[static bay]

How floats do what they do is kinda complicated.

Just know that the default is integers, which are whole numbers.

You use them for counting things and math.

Floats represent all the real numbers. You use them for math and more math.

[flint heath]

🤣

good to know

is there any c# documentation that contains examples for most things? I've used documentations with examples before and they made it a lot easier to understand how certain scripts can be used and to learn languages as a whole

[charred spoke]

https://learn.microsoft.com/en-us/dotnet/csharp/

[vale karma]

how would i go about having a selection of buttons all going to different scenes, kind of like a game selection menu.

[rich adder]

use grid layout group

[charred spoke]

Do you know how to make a single button do something ?

[vale karma]

i looked at that but didnt know how to use it exactly

and yea, but i dont want to code 32 different buttons on one screen

[rich adder]

run a for loop and instantiate the buttons / thumbnail objects in the grid layoutgroup

[vale karma]

okay

[rich adder]

make a prefab for one should look like / button component on it. then from there have a script linked to all the componets to change like icons

[vale karma]

i wanted to use grids for a Supermarket simulator but for a PC repair shop, and ran into issues using grids so i gave up i suck

ive realized even though i have the power of god and anime on my side, I cant find it progressive to sit and stare at a big project forever and get discouraged. So i asked chatgpt to come up with a list of 32 games from easy to hard to make for beginners. I plan on putting it all together and refining it into a lil pack 😛

[vale karma]

Im a bit confused on how i would make an image go to the designated spot? ig ill play around

[jaunty condor]

HI. I can't do a certain thing in my game. when I hit an object, it deactivates and reactivates another cube. These cubes have a specific tag. How do I tell to activate cube for example 1, after hitting cube 0, and then for example when I hit cube 1, it deactivates and activates cube 2. I tried searching on google, but I can't find anything :(

[eternal needle]

Store which object you want it to affect on each cube. You can drag the reference in inspector

[jaunty condor]

yes but, I want cube 1 to be activated when I hit cube 0 etc. How do I write this into the program?

[jaunty condor]

because there are not just two cubes, but many

[vale karma]

oooo i did ittt i feel smart 😮

[eternal needle]

Store which cube you want to be activated on each cube. With a script
Activating and deactivating should just be through some public method on the cube script, so that the cube handles the logic.

[eternal needle]

If you need a very specific structure to it, itll have to all be assigned manually in some way

[jaunty condor]

okk, i try, thx

[vale karma]

How would i be able to make the grid usable after instantiating prefabs? I cant exactly use the scripts on the buttons and match them with scenes i think

i dont have any access to it until runtime

[static bay]

What's the issue?

[vale karma]

I got the grid layout working, it instantiates the button w/ image on the correct spot. But how would I get it to do anything at runtime if i cant reference it before runtime?

[eternal needle]

You can add listeners at runtime

[vale karma]

whos listenin?

[static bay]

Buttons have an OnClick unity event.

You can add a callback through code.

[vale karma]

how would i reference the script to it tho

[static bay]

Reference what script?

[hoary ice]

while (true)
            {
                // Go to the throne location with offset
                agent.SetDestination(throne.transform.position);

                // Wait for 3 seconds at the throne location
                yield return new WaitForSeconds(3f);

                // Go back to the work location with offset
                agent.SetDestination(workLocation);

                // Wait for 3 seconds at the work location
                yield return new WaitForSeconds(3f);
            }

this loops for like only 3 times then they will get somewhat stucked in the position

[vale karma]

im realizing i can just put the script on the object. im dumb

[hoary ice]

they do like this

[slender nymph]

you're probably starting a whole bunch of those coroutines

[static bay]

You can create a button prefab that has a script that causes a scene transition. When instantiating the button, you tell that script what scene it's supposed to transition to.

[hoary ice]

based on the script i only have 2

[static bay]

You could also just directly add a listener to the buttons "OnClick" unity event, and just specify what scene to transition to. Something something anonymous methods.

hello

i am a beginner

i am looking forward to introduce myself and meet all the fellow members and experience how the creation team works !

[vale karma]

ahh i might need help doing it right, i think im doing it just slowly

[static bay]

that's fine

[vale karma]

like now i have a method to loadbysceneindex... but how do I give a number to the scenes at runtime, or do they need to be given at runtime?

[languid spire]

the number is assigned when you add the scene to the build settings

[vale karma]

how would i reference the number? would i drag it on a reference i make myelf? or is it a method built in to unity already?

unless i need to make a dictionary or soemting

[languid spire]

https://docs.unity3d.com/ScriptReference/SceneManagement.Scene-buildIndex.html

[vale karma]

thankyou, trying chatgpt seems to do more harm than good

[languid spire]

no surprise there

[vale karma]

haha i think the only good thing it did was build a controller that used character controller and 3d pov

i think 5 minutes faster debuging it than making it myself

is it better to loadscenemode.single or additive most the time?

[languid spire]

that depends purely on your game design

[barren vapor]

Chatgpt is a text-/languagebot. It's not perfect in creating or improving code. Just like decrypting stuff like Sha256 or smt.

[vale karma]

yea it basically makes stuff up. Right now im finding a problem with referencing the scenebuild number. I made a build and have the button code written and ready to go, but like... how XD i think im just blind

    public void LoadBySceneIndex(int index)
    {
        SceneManager.LoadScene();
    }

im stuck at what to code to for the value index

[languid spire]

the documentation is full of information
https://docs.unity3d.com/ScriptReference/SceneManagement.SceneManager.html

[vale karma]

ookay okay were getin somewhere

[languid spire]

man, your first action should be to RTFM

[vale karma]

lol yea i start there, but get confused fast. Theres alot more there than i need but i dont know exactly what im lookin for. So it takes a while

[honest haven]

        money.text = GetComponent<CoinUI>().amount.text;``` is one faster then the other? trying to work out the difference

[iron hull]

its a pretty good tool for psudocoding if you're lazy, but when you're new you'll be referring to docs a lot

[languid spire]

the first does not need to look up a reference because it already has one. The second has to refer to Unity to get a reference so the first is much more efficient

[iron hull]

adding onto the above statement its efficient because you dont want to be going GetComponent<>() calls every update if you can avoid it

[honest haven]

The reason i ask is becuase its a DDOL and when i load the scene the field says missing, yet the clone Coin UI is there. Could it be a who loaded first issue?

are DDOL loaded before normal gameobjects?

[iron hull]

you can try using SceneManager.sceneLoaded to test?

[languid spire]

tbh the code makes no sense as the component seems to be in the same gameobject so why would it need a singleton instance reference in the first place?

[honest haven]

im calling it on my battle manager its its own UI, and CoinUI is its own UI

need to get a ref to the amount

[languid spire]

then your GetComponent call is nonsense

[honest haven]

yh im using sington, is that also wrong?

[iron hull]

they're saying the second line is redundant if you use the first line

[languid spire]

if CoinUI is DDOL and a singleton, no

[honest haven]

yh, but the singleton amount is missing

[languid spire]

impossible

ah, is the TMP also DDOL?

[iron hull]

[honest haven]

yh its part of ddol

it sits in the ui

[languid spire]

should not lose the reference then

[honest haven]

battle manager is not a ddol

but coin ui is

[languid spire]

what is battle manager? where this code is being executed?

[honest haven]

yes, want me to make a quick video?

[languid spire]

no

if Money is correct when you ddol CoinUI and the TMP referenced is also DDOl then there should be no problems

[iron hull]

also to clarify , your UI itself is ddol ?

or just the singleton

[iron hull]

In battlemanager on its start/awake are you referencing money = CoinUI.instance.money?

or smth like that

[honest haven]

yh

money.text = CoinUI.instance.amount.text;

hang on i am setting the .text should i be setting the gameobject?

[iron hull]

I mean either work but you only want text in this case so text is fine i'd assume

[honest haven]

yh so im thinking maybe its a load issue? maybe battlemanager is being loaded before the DDOL?

but would that not throw a null ref error or somthing

[silver girder]

is it possible to convert 1st person camera to 3rd person camera?

[iron hull]

have two cameras and switch their .enabled if you want to do it in runtime, or just move the camera in the scene

[silver girder]

so i just move the camera from the capsule and put it behind the player?

and btw to add sfx do i need to create a file named ''sfx'' and add audio source?

because i am a beginner im trying to learn and help

[iron hull]

try running CoinUI.instance.amount.text from both scripts on each scene load maybe? is there a problem with the reference before the scene loads

[silver girder]

i am currently trying to make a soccer / football game but i am lost

[iron hull]

you can call it whatever the heck you want
its just good practice to call it names that you'll be able to understand (and potentially others)

so sfx is good start

[silver girder]

thx i am literally looking up for tutorials but cant seem to find any soccer game tutorials 😦

[iron hull]

you can look up tutorials for things you need rather than a game specifically and stitch it all together

[honest haven]

ok i fixed it

https://forum.unity.com/threads/dontdestroyonload-object-reference-goes-missing-after-scene-change.795126/

    {
        //Singleton method
        if (instance == null) {
            //First run, set the instance
            instance = this;
            DontDestroyOnLoad(gameObject);
 
        } else if (instance != this) {
            //Instance is not the same as the one we have, destroy old one, and reset to newest one
            Destroy(instance.gameObject);
            instance = this;
            DontDestroyOnLoad(gameObject);
        }
    }``` i added this

    {
        if (instance == null)
        {
            instance = this;
            
            DontDestroyOnLoad(gameObject);
        }
        else
        {
            if (instance != this)
            {
                Destroy(gameObject);
            }
        }
    }
``` instead of this

but i dont no why that would work

[silver girder]

cant find

[languid spire]

it's actually pretty obvious. In your first code you are replacing the instance in second you are not. So the instance was not being carried over from scene to scene

the comment even tells you this
//Instance is not the same as the one we have, destroy old one, and reset to newest one

[honest haven]

but why would the instance not be the same

is what i mean

[languid spire]

because it is coming from the newly loaded scene

[honest haven]

ok so even tho its a ddol on a new scene it creates a clone, would that then mean its a new instance?

[languid spire]

yes, of course

[honest haven]

ok i understand now thanks steve

[languid spire]

question is why do you have the same object on multiple scenes if you are going to ddol it?

[honest haven]

Well i wanted to carry the amount over to a new scene

i.e the coin u

[languid spire]

that makes no sense

the ddol object will exist for ALL scenes, so no need to duplicate it per scene

[ebon robin]

So I reworked the FSM code, states no longer reference StateMachine. The StateMachine now checks transition by using a Func<bool>, but uhh it's got lot more spaghetti than I thought. Could someone check for me if this feels right?
https://gdl.space/ecurofotiw.cs

[honest haven]

Can you explain a bit more, where you think my mistake is so i can understand. I thought i was doing DDOL correct with my awake instance.

[languid spire]

this

 private void Awake()
    {
        if (instance == null)
        {
            instance = this;
            
            DontDestroyOnLoad(gameObject);
        }
        else
        {
            if (instance != this)
            {
                Destroy(gameObject);
            }
        }
    }

is what you need in one scene, nothing more
I am assuming this is on your CoinUI class
because instance is static it can be referenced from anywhere without an additional reference
CoinUI.instance gives you all you need
the only thing you need is to make sure that the only things that the instance references are also DDOL

[silver girder]

guys please can you tell me how to make a soccer game cuz i am new 😦

why do my setting up transitions takes like 40 lines

does anyone have a better way of setting up transitions for statemachine

[sullen canyon]

Hi everyone, is this the correct way to use lock statement in C#? My game has multiple threads accessing the Inventory simultaneously. Thanks

[wintry quarry]

no this isn't going to do anything really

because you're just locking around accessing the list reference. But once the caller has a reference to the list you have no control over when or where they access it or modify it

My game has multiple threads accessing the Inventory simultaneously
I question the motivation of this

[tall delta]

"multiple threads accessing the Inventory simultaneously" I have no idea why on earth you'd want to do this. but I'd recommend using the built-in concurrent collections.
https://learn.microsoft.com/en-us/dotnet/standard/collections/thread-safe/

[sullen canyon]

I want everyone in a guild to be able to access the guild's inventory at the same time, I want to learn how to synchronize

I still don't know if what I'm doing is really right

[tall delta]

well if it's a multiplayer thing, you'd still want to do it 'in order' synchronously on the server, based on the order of the packets

[shell matrix]

Anyway this is a code related channel

[ornate lynx]

hi, is there a built-in function that detects the number of keys being pressed at once?

[wintry quarry]

No. Also keyboard hardware will severely limit this anyway

[ornate lynx]

no like....at least two keys?

[keen dew]

That seems like a strange requirement. What are you planning to use it for?

[ornate lynx]

unity struggles to run an animation when the player is walking diagonally so i thought instead of detecting every two keys which would result in 4 if statements, i would detect if two keys are being pressed, if one of them is the up arrow key, i'd run the animation of going up, if it's the down arrow key, i'd run the animation of going down

[keen dew]

You can do that in 2 if statements

[ornate lynx]

well

that is if i detect if 2 keys are pressed

[keen dew]

I also don't get why you need to check if other keys are pressed, just check if up key is pressed -> always play the up animation, if down key is pressed -> always play the down animation

[ornate lynx]

yeah but i have other if statements for when only the right or left key is pressed

[keen dew]

Why is that a problem?

[ornate lynx]

because now unity tries to play both animations

going vetically and horizontally

[keen dew]

Only because you tell it to do that

[rich bluff]

is it 2d?

[ornate lynx]

yeah

[ornate lynx]

well two conditions are met there, going right, and up for example, so it keeps switching back and forth from both animations

[rich bluff]

you tried using blend trees? i dont know how well they work with 2d but in 3d all you need is to provide the direction vector in the form of 2 float params to a blend tree

[ornate lynx]

well no, idk how to use them

[keen dew]

Yes, because that's how you've organized the code

[ornate lynx]

but hold on i think i might have a fix

[rich bluff]

just right click in AnimatorController and create a blend tree and check it out

[ornate lynx]

sounds fun

[ornate lynx]

u know, that makes sense, imma try to change it

[vast vessel]

why is Destroy(); not running?

as you see in the second image, i am invoking the action, which is Destroy();

any errors?

[rich bluff]

does execution reach that line?

you ran the debugger and the line is hit?

[vast vessel]

yes, the invoke line is being reached, but the Destroy(); method is never called

[tawny hedge]

hope this is okay to post/ask: is there a way to change the font/material face color slowly and fade between each colour or just cycle through the rainbow, similar to the video?

[vast vessel]

you can see the break points in the images

[rich bluff]

and when you step into what happens?

[vast vessel]

wdym "step into"?

[rich bluff]

debugger step into button/hotkey

F11 i think by default

[vast vessel]

when i press the button, the yellow marker moves to the next line

[rich bluff]

look into destroy object, maybe something like invocation target is null or something else

this can be some closure/uobject related fuckery, i dont know

[vast vessel]

the flechette value, is not null

[cosmic dagger]

If it's a TextMeshPro text, you can change or animate the color in code . . .

[rich bluff]

which c# version is that?

your delegate type is Action<T> but you pass Action<void>

[vast vessel]

well what do i do?

never used actions before

[rich bluff]

i just dont know how it even compiles, but in case when you need to match signatures you can wrap it into a lambda

DirectHit(..., x => { Destroy(); }, ..)

[vast vessel]

method needs to return Hunter_Flechette right?

[rich bluff]

nono thats just your DirectHit

you pass it, as a lambda that already matches the signature of Action<T>

x is the argument

you just dont use it inside the lambda, since Destroy() has no params

[vast vessel]

dude i dont get it

[rich bluff]

what exactly?

i also dont get how it allows you to pass in an Action, when the signature has Action<T>

[vast vessel]

anything you've sent since this message

[rich bluff]

just try the x => { Destroy(); } instead of Destroy

if it works ill explain what you dont understand

[vast vessel]

like this? config.DirectHit(this,rb, x => { Destroy(); }, collision);

[rich bluff]

yes

[vast vessel]

it works!

[rich bluff]

ok, can you change destroy to Destroy(Hunter_Fletchette x) ?

[vast vessel]

why not

[rich bluff]

in terms of your architecture

because you may want unified Destroy() across all your classes

otherwise each will require random bits of params

[vast vessel]

this is just for object pooling, and its only used in this class

[rich bluff]

now you can just pass it without the lambda

as it was before

[vast vessel]

right, so before it didnt take any perams, but now it takes x of type Hunter_Fletchette, which the action passes that x onto the method. correct?

[rich bluff]

someone more up to date may explain why compiler allowed you to pass in a delegate with signature mismatch

[rich bluff]

yes, param and passed delegate have the same arguments, which you tested with a lambda, so that was the cause of it not working, but for .net 4.8 it wouldnt even compile

actually not .net just old c# version

i cant find anything on the topic, cant come up with good search terms, but my guess is, if it is a feature in new c# and not a bug, it may try to generate a delegate that matches the sig under the hood, and because unity doesnt fully support all new c# features it may fail at that

[queen adder]

when I jump beneath the coin, my player touches it and falls down, I want my player to jump equally at all times. 2D game

[tawny hedge]

thanks for the reply, unfortunately haven't been able to accomplish this though 😂

it is a textmeshpro

but im trying to change the face - color of the font material if possible, the material font is only attached to one text object

[scarlet skiff]

any tips?

#854851968446365696 people on mobile can’t see that

Can you also send a screen recording of what’s happening?

[silver girder]

me?

[thorn holly]

Yes

[silver girder]

okay

[thorn holly]

Why are you calling me? Send a screen recording in here of what’s happening.

[silver girder]

i dont have a recording app

okay i will download it and send

Is there a standard pattern for automatically unsubscribing from all Actions in OnDestroy() ?

[silver girder]

i will upload the vid

[swift crag]

if you're talking about unsubscribing from events (or more generally removing yourself from delegate fields), then no, not really

for input system callbacks, I'll make a Dictionary<InputAction, System.Action<InputAction.CallbackContext>> so that I can iterate over it to subscribe and unsubscribe, at least

[silver girder]

https://youtu.be/2zy8WWU48Xs

[queen adder]

Instantiate(bullet, SpawnLocation, Quaternion.identity);
``` When I do this it starts infintely spawning bullets, I want it to spawn only once. 2d game

[grizzled zealot]

Can you provide a brief code example for that? Do you statically declare the dictionary?

[swift crag]

nah, I just fill it out in Awake :p

is it maximally efficient? no, but i'll survive

I do want to figure out a way to detect when I forget to unsubscribe from events

[thorn holly]

What exactly is the problem? What is happening in that recording that you don’t want to happen?

[swift crag]

other than just changing scenes and destroying objects and seeing if an error falls out

[silver girder]

go to 1:00

[sonic dome]

how do i use vector3.rotate towards for lets say i press A and i want it to rotate left?

[silver girder]

and go to 1:44

[wintry quarry]

How much "left" do you want it to rotate?

And over what time period?

[sonic dome]

little

[wintry quarry]

That's pretty vague

[sonic dome]

ill go with just time.deltatime * some speed

[thorn holly]

What is going wrong? Looking at your code, the behavior seems to be expected. What is the issue here?

[wintry quarry]

Transform.Rotate will be simpler

[sonic dome]

i mean it should be like a game rotation like slowly uk

[wintry quarry]

No idk what a "game rotation" is

[sonic dome]

whats the difference?

[sonic dome]

umm i mean like how do i even say how much it rotates

lets say 90

[wintry quarry]

Transform.Rotate lets you specify how many degrees to rotate

[silver girder]

when i add the script to the player and ball it gets anchored and when i delete the scripts the ball acts normal with the physics

[sonic dome]

okk let me try

[wintry quarry]

RotateTowards rotates towards a certain rotation. Not necessarily a certain amount

[thorn holly]

Post your code

[sullen epoch]

Hello There. I have an enemy prefab that requires the player & cameras transform transform. however every time I move it into my scene I have to reassign the players transform to the script, what's the best way to automate this?

my thoughts on this is to create an empty game object and create a script containing public variables for all my references so instead of assigning the variable directly to my enemy controller script I could replace it with something like "Refernces.playerTransform"

[silver girder]

ok i will post the two codes

[sonic dome]

so if i want a smooth rotation like in games like gta 5 and watch dogs2 its perfect right?

[wintry quarry]

That's extremely vague. Lots of things in those games rotate in a lot of different ways

[hazy crypt]

you can do a findgameobjectwithtag and assign that on start awake

[sonic dome]

😭 how do i explain

[wintry quarry]

Words? A video?

An explanation?

[sonic dome]

let me try with transform.rotate(0,0,20f)

then ill try

[thorn holly]

Not like that. Delete that and use one of these !code

[sonic dome]

i think transfrom.rotate is not right cuz its instant i want it to slowly rotate

[hazy crypt]

heres what ive used before

[sullen epoch]

ill have a read thank you

[hazy crypt]

You can also make the players transform a public static set of vales and then reference them from another script

[sonic dome]

nvm works fine thanks

[thorn holly]

Yes, that is definitely a large code block. Let’s start from the beginning. Delete that giant block of code you posted. Put your question, the recording, and both scripts in one message.

[silver girder]

i dont understand

[thorn holly]

What don’t you understand?

[silver girder]

deleting "giant blocks" of code i posted and putting question and recording and both scripts in one message

[thorn holly]

First step, delete this.

[silver girder]

okay

deleted

2nd step?

[thorn holly]

It’s still here.

Delete the message in which you sent the scripts

[silver girder]

i deleted it from unity studio

[wintry quarry]

just rotate by a little bit at a time. There's no difference

[thorn holly]

No, sorry, that’s not what I meant.

[sonic dome]

yea just saw that thanks

[wintry quarry]

Vector3 rotationPerSecond = new Vector3(0, 50, 0); // 50 degrees per second
transform.Rotate(rotationPerSecond * Time.deltaTime);```
@sonic dome

[silver girder]

np

[thorn holly]

Alright, put the scripts back into unity studio. Use this message to copy and paste into a new script file as needed.

[silver girder]

okay

all scripts except Target script are there

@thorn holly

[sonic dome]

oh thanks

[thorn holly]

What happened to target script?

[silver girder]

deleted it from unity studio

[thorn holly]

Can you recover it?

[silver girder]

added it back

[thorn holly]

Okay, so everything is how it was originally?

[silver girder]

yea

[thorn holly]

Next step: delete this message.

[silver girder]

deleted it

[thorn holly]

Next step: make a message that looks like this.

@thorn holly

[thorn holly]

“What is happening to my script” isn’t your question. Describe what exactly the problem is.

[silver girder]

i edit it

edited

[thorn holly]

Good job. I know that was tedious, but it’s important to format your question correctly. Now we can figure out what’s going on

[silver girder]

alright bro thank you !
i hope you find the issue and report it by maybe editing it or send me a short snippet that can help me edit the scripts !

[thorn holly]

I think I found the problem. Your setting the ball’s isKinematic to true, do you know what that does?

[silver girder]

no i dont

[thorn holly]

Basically, that makes it not use physics. Something that is kinematic can only be moved explicitly through script, not with the physics engine

Is this code from a tutorial or chat gpt or something or did you make it yourself?

[silver girder]

so do i write "isnt kinematic""

[thorn holly]

No

[silver girder]

from a tutorial but wrote it myself

[thorn holly]

Do you know basic c#?

[silver girder]

no

[thorn holly]

You should definitely learn the basics of c# before using unity

[silver girder]

aw man

[thorn holly]

Well, I mean, you have to be able to make your own code if you want to develop.

I reccomend using codecademy to learn c#, but there are many online tutorials you can use

After you learn c#, learn the basics of unity here : !learn

[eternal falcon]

:teacher: Unity Learn ↗

Over 750 hours of free live and on-demand learning content for all levels of experience!

[thorn holly]

Then you’re ready to start developing

[silver girder]

idk how

[thorn holly]

So to be able to make your own code, you have to learn c#

[silver girder]

how much can it take to learn it?

[thorn holly]

? Do you mean how long does it take?

[silver girder]

yes

[thorn holly]

You can’t really quantify that, it varies a lot between what tutorial you’re using and from person to person. Codecademy estimated their tutorial takes about 20 hours.

[silver girder]

20 HOURS JUST TO LEARN??????!!!!!!

[frosty hound]

Don't be so dramatic

It takes longer "just to learn". Have you never spent time learning a new skill before?

[silver girder]

i have

[sullen epoch]

thanks for your help earlier if I cache the results like so

    void Awake()
    {
        rb = GetComponent<Rigidbody>();
        healthBar = GetComponentInChildren<HealthBar>();
        player = GameObject.FindGameObjectWithTag("Player");
        playerTransform = player.transform;
    }

will it negate the performance cost of using FindGameObjectWithTag? I intend to have a large amount of enemies.

[frosty hound]

Then you should be smart enough to know it takes time to get anywhere.

[thorn holly]

20 hours to know the basics. Beyond that, you will be constantly learning.

[silver girder]

ah okay 😄

[thorn holly]

So yeah, learn c# basics, use unity learn, and then you can start developing

[silver girder]

something is wrong..

[thorn holly]

What is?

[silver girder]

they told me to write " $ dotnet run" i wrote it but didnt write anything

oh yea figured it out

[thorn holly]

Just keep following the tutorial

[frigid sequoia]

I literally just did a couple of simple tasks in Java and CSS on a course and then jumped to Unity Learn and finished the Code part in like 2 weeks?
Now I don't know many, many things, but I feel kinda confortable coding

[thorn holly]

Cool

[frigid sequoia]

So it is not really hard, just takes some getting use to it, like everything

[silver girder]

thx

wetnoodle11 and all members who helped god bless you guys

[thorn holly]

Of course! We’re here to help.

[silver girder]

yooo

created something in c#

just by learning WOOO

[sullen epoch]

anyone able to provide feedback on this?

if I cache the results like so

    void Awake()
    {
        rb = GetComponent<Rigidbody>();
        healthBar = GetComponentInChildren<HealthBar>();
        player = GameObject.FindGameObjectWithTag("Player");
        playerTransform = player.transform;
    }

will it negate the performance cost of using FindGameObjectWithTag? I intend to have a large amount of enemies.

very much appreciated as always.

i'll happily provide additional context if need be

[wintry quarry]

it doesn't "negate" it. It just means you only pay the cost once, and right when the object is created.

[hazy crypt]

as long as you ony run this in awake it should be fine, you wouldnt want to run it un update. there is a seperate method called FingGameObjectsWithTag which will return an array of objects with the tag. That can be super useful, I use it to track the collectibles in my scene.

[sullen epoch]

Brilliant, Thank you both

[silver girder]

waa the codeacademy is paid

i will take a break

[sleek orchid]

Hello! My Intelisense seems not to be working anymore, any hints?

Does anyone know how to fix an android app icon?

Can't seem to get it to fill the icon space , google keeps adding the white boarder

[queen adder]

Instantiate(bullet, SpawnLocation, Quaternion.identity);
``` When I do this it starts infintely spawning bullets, I want it to spawn only once. 2d game

[timber tide]

perhaps show more than a single line of code

[queen adder]

theres nothing else

except spawnlocation vector2 and public gameobject bullet

I dont have a problem in code I just do not know how to do it

[swift crag]

of course there is something else

you can't just slap one line of code into a script file and have it work

share the entire script.

[queen adder]

public class bulletSpawn : MonoBehaviour
{
    public GameObject bullet;
    public Vector2 SpawnLocation;
    

    void Update()
    {
        spawnbullet();
    }



    void spawnbullet()
    {
        if (Input.GetKey(KeyCode.Space) == true)
        {
            Instantiate(bullet, SpawnLocation, Quaternion.identity);
        }
    }
}

[swift crag]

compare these two methods

https://docs.unity3d.com/ScriptReference/Input.GetKey.html
https://docs.unity3d.com/ScriptReference/Input.GetKeyDown.html

[queen adder]

i KNOW the difference

[swift crag]

Then you know how to solve the problem.

[charred heart]

I have a class with two modes, and this class will switch between them. What is an effective way to implement "mode"?

For example, if I use the flags Mode1 and Mode2, I'll check to see if Mode1 or Mode2 return true before proceeding with any logic.
Another example is use polymorphism. But it's only have 2 modes. Is it worth it?

[crimson sinew]

What exactly changes between modes?

[wintry quarry]

Use an enum

[charred heart]

My NPC system have 2 type of behavior. 1 behavior is following preprepared data (i named it PathAction), 1 behavior is following state machine. 
They first running around the scene using PathAction. If player or the environment impact them, they may switch to the statemachine.

[crimson sinew]

That sounds perfectly reasonable to just do with an enum

[silver girder]

how do you make a shooting ball cuz i have no idea 😦

[cosmic quail]

https://www.youtube.com/watch?v=fW3bHYaSxLU

[silver girder]

nooo

not that

its okay if you didnt understand

what i want is like handball shooting

[summer stump]

Well the question was incredibly vague

[scarlet skiff]

any tips?

[silver girder]

basicaly throwing

[cosmic quail]

in vr?

[silver girder]

no

pc

[cosmic quail]

then its the same isnt it

[sonic dome]

        if(Input.GetMouseButtonDown(0))  <--- this is in update
        {
            if(!attack1)
            {
                anim.SetTrigger("attack1");
                attack1 = true;
                StartCoroutine(combo());
            }
            if(attack1)
            {
                anim.SetTrigger("attack2");
            }
        }
    }

    IEnumerator combo()
    {
        yield return new WaitForSeconds(10f);
        attack1=false;
    }

why is it that both the attack animations r being triggerd one the 1st press?

[silver girder]

idk

[summer stump]

Vr is done on pc generally

[silver girder]

can you send me a tutorial of handball shooting i am really lost

[silver girder]

yo thx for that information

[cosmic quail]

just shoot it with less force i guess, then it goes from being like a bullet to being like a thrown ball right?

[summer stump]

You first have to describe what you want clearly and with detail

[languid spire]

 if(!attack1)
attack1 = true;
if(attack1)

review your logic

[cosmic quail]

but if u google ball throwing tutorial then you will find that too https://www.youtube.com/watch?v=ZonVUxvZiwE

[silver girder]

with character tho

[sonic dome]

yea i used else if then its kidna sorted by bad

[silver girder]

capsule that throws ball

like handball passing

[summer stump]

We are not your personal google. JohnSmith is just googling what you are saying. You can do that yourself

[silver girder]

idk how

[silver girder]

like i cant find them

[summer stump]

You are being too specific then. Johnsmith gave you a tutorial that will handle part of it. Now look for how to animate

Combine those

Bam

[cosmic quail]

this? https://www.youtube.com/watch?v=vduSC2YHFnw

[silver girder]

thx and sorry for disturbing everyone

[silver girder]

sorry for you too

[round tulip]

I have this problem where if I move my player it jitters. I am using a cinemachine/pixel perfect camera. The sprite is (supposed to be) 32 units with point filter and no compression. I think the problem is because of the camera movement, but I dont know. Can someone help me with this?

[vapid mesa]

hi, i try to make animation systeme but it did'nt work, the parameter don't change i think is the link between the 2 scripts

[lost anvil]

im having an error popping up saying that the unity first person character controller script cant find my stamina script and i dont know why.

stamina handler - https://gdl.space/edogipijuz.cs
player controller - https://gdl.space/ajejikiwem.cs

[swift crag]

You have not serialized FpsController, so you can't assign it in the inspector, and nothing in your code assigns anything to FpsController

[vapid mesa]

fps controller is from this script

and before my animation script was in my FPScontroller script

[swift crag]

yes, and you need to tell Animation how to find the FPSController

adding [SerializeField] to the field will make it appear in the inspector

then you can drag a reference in

[vapid mesa]

okay i see

thks

it work

[lost anvil]

bump

[languid spire]

it might help if you provided FULL information

[lost anvil]

what do you want

[languid spire]

what do you think?
A screen shot of the error
A screenshot of the object involved
The normal stuff

[lost anvil]

i think this, theres no object

[summer stump]

Why crop it so much?

And he wants a screenshot of the object involved too

[languid spire]

He always does this, drip feeds information

[frigid sequoia]

Guys my light ran out while compiling yesterday, now I get all these errors and I have no idea what any of them mean

[languid spire]

Close your project then Delete both the Library and Temp (if it exists) folders

[queen adder]

I made rigidbody2d and wrote script for bullet to move, in editor I attached the script to my player, and in the rigidbody2d field I dragged my bullet gameobject. And the bullet wont move, however if I make new script and attach it to the bullet gameobject in editor it works. Does that mean it is not possible to move any other gameobject than the one script is attached to?

[lost anvil]

what object involved the player controller or the stamina bar ui

[summer stump]

Just give everything you can. Don't make us drag stuff out of you. Don't crop it too

[lost anvil]

sir yes sir

stamina handler - https://gdl.space/edogipijuz.cs
player controller - https://gdl.space/ajejikiwem.cs

[languid spire]

from your code both scripts should be on the same object.
Also any other errors in the console?

[lost anvil]

i dont know what else you would want

no

[summer stump]

Selecting three things together means the inspector shows nothing useful....

[lost anvil]

lol what do you want selected

what the 2 scripts are attached to?

[languid spire]

Stamina Controller is in a different namespace

[silver girder]

how to fix the "Can't add script component 'BasicEnemyDone' because the script class cannot be found. Make sure that there are no compile errors and that the file name and class name match."?

[lost anvil]

okay so how do i put it into the same one? via namespace blahblah at the top of stamina script?

[silver girder]

hey do you wanna create a fps character?

[lost anvil]

ive got one mate im fixing it

[silver girder]

ah

alr

how to fix the "Can't add script component 'BasicEnemyDone' because the script class cannot be found. Make sure that there are no compile errors and that the file name and class name match."?

[lost anvil]

am i not putting the stamina script into the same namespace with using UnityStandardAssets.Characters.FirstPerson;

[languid spire]

no

[lost anvil]

how would i go about doing that

[summer stump]

Do you have compile errors? Does the class name match the file name?

[silver girder]

yes

[silver girder]

that's the issue

[summer stump]

Which one of the two?

[languid spire]

does the folder where the character controller is have an asmdef?

[silver girder]

the class name match the file etc

[lost anvil]

what is asmdef

[summer stump]

Etc?

Then rename the class ?

What is the issue?

[silver girder]

yes

the rename thingy

[summer stump]

Then do it

[silver girder]

i did

[lost anvil]

this?

[silver girder]

but still doesnt work

[languid spire]

ok it doesnt, so you can just put your Stamina Controller into the same namespace as the char controller

[silver girder]

is there a solution??

[lost anvil]

cheers 👍

[summer stump]

Give us info to actually help with...
Show the file, show the class, show the console

[silver girder]

i will record

[summer stump]

No thank you

Pictures would be much better

[queen adder]

My 2d character shoots shurikens, is it possible to make them roll (rotate ) forward through script or would it be better to make animation?

[silver girder]

ah okay

[queen adder]

Did you take the previous advice on taking some C# learning? The basics will really help you if you take the Pathways over at Unity Learn !learn

[silver girder]

i diiiid

[summer stump]

This is none of the things I asked for

Show the class, the file, and the console

[silver girder]

ah alr

by class wdym

in the script?

[summer stump]

Inside the script you would have written
public class Something
(or it was generated automatically)

[summer stump]

Yes

[silver girder]

oh ye ik that

[summer stump]

Which pathways did you complete?

[silver girder]

wdym

console:

[languid spire]

So you have compile errors. Did you not read the error message?

[summer stump]

You said you did the learn pathways as suggested here
#💻┃code-beginner message

[silver girder]

class

[summer stump]

BasicEnemyDone is not BasicEnemy

You said you renamed it

[silver girder]

yea

i did

[summer stump]

Show the file I guess. Is it called BasicEnemyDone?

[silver girder]

yea

it is called basicenemydone

[summer stump]

basicenemydone or BasicEnemyDone ?

[silver girder]

2nd option

[languid spire]

And what does this say?

[summer stump]

So then the issue is that you are referring to BasicEnemy in other scripts

[silver girder]

ahhhhhhh

[silver girder]

can a drag & shoot tutorial work with this ?

[summer stump]

Why not 🤷‍♂️
There are tons of tutorials. You can change things. C# is turing complete and you can do literally anything code can do

[silver girder]

ooooo

[silver girder]

thxx

[vapid mesa]

hi, I have a script for animator but the parameter don't work with the spacebar

when i jump the parameter don't change

[summer stump]

You have one parameter for everything and just set an int value?

Very interesting, never seen that

[languid spire]

It wont you set the int to 30 and then immediately back to 0

[queen adder]

Honestly mate, I highly recommend you starting with the Unity Essentials Pathway over at https://learn.unity.com/, you will learn the basics and start creating things straight away, and it will be much more fun. Right now you are spending most your time troubleshooting.

[vapid mesa]

he don't go to 30

[silver girder]

i did i am still learning from it

[vapid mesa]

it work for all other animation

but not the jump

[silver girder]

i just find difficulty understanding a bit so i come here 😄

[frigid sequoia]

Like the whole Library folder? I don't think I have anything called Temp

[summer stump]

When you jump, you are no longer grounded

[frigid sequoia]

Sure this doesn't break anything?

[summer stump]

So it sets it to 0

And this happens too fast for you to see

[summer stump]

Yes. And no it will not break anything

[vapid mesa]

ye but the fall animation is on exit

[queen adder]

Yeah that's fair enough, like I don't want to sound like I'm discouraging you from doing your own thing and seeking help on here, that's what this community appears to be for.
I'm just talking from first hand experience as I'm currently going through the Pathways, having finished the Unity Essentials last week and moving onto Junior Programmer. Anyway good luck on your tutorials.

[silver girder]

thanks and god bless you and dont worry your arent discouraging me i have enough courage to make the game and to ask here about problems and difficulties i have experienced !

[summer pulsar]

hello, is there a way i could the script run only if the requirements are met ? instead of throwing an error it stops the script ?
for example if i try to reference a box collider in a sphere instead of throwing an error the script wont work, is that possible ?

[silver girder]

i think it would work if the item iskinematic wich means works only with script

[silver girder]

i personally i aint a proffessional at this kind of thing as i am a learner

but still i wanna find a way to get useful for this community

[crimson sinew]

C# has an is keyword you can use I guess? or you can check it for null, I'd need more context

[languid spire]

please don't until you know what you are talking about

[silver girder]

okay sorry 😦

[shell zephyr]

Hello! I want my game to finish once the rigidBody2D speed is = 0. how can i do it?

private void FixelUpdate()
    {
        rb2d.velocity = new Vector2(4f, rb2d.velocity.y * dashingPower);
        speed = rb2d.velocity.magnitude;

        if (speed == 0)
        {
            Debug.Log("El juego termino");
        }
    }`

[summer pulsar]

for now i just need the initial step to do it so im experimenting with things that were problems ive ran into before or other i think i would benefit from in the future

[crimson sinew]

oh, you mean if the box collider fails to be found?

that would just be null I believe

[summer pulsar]

yes

[crimson sinew]

if (boxcol == null) <disable script here>

[summer pulsar]

thank you kind beast

[cosmic dagger]

does the log appear when the speed is 0?

[shell zephyr]

No ;(

[cosmic dagger]

what method runs this code?

also, you should check if it's 0 or less, or use Mathf.Approximately . . .

[shell zephyr]

you mean the RigidBody2D?

[cosmic dagger]

what method is this code inside of?

place a log inside of the method that runs the code you use to check the speed (to make sure it's running) . . .

[shell zephyr]

i don't know how to check it 🥺

[cosmic dagger]

do you know what a method is?

[shell zephyr]

void

[cosmic dagger]

void is a return type . . .

[summer stump]

No

[shell zephyr]

👺

[cosmic dagger]

you've been coding so far, where do you place your code within the c# script?

[shell zephyr]

Oh, I used this one on the player

is that what you asked?

sorry, i'm just so bad with coding xd

[cosmic dagger]

no, but this is basic c# you need to know, especially to receive help properly . . .

it's hard to suggest fixes or solutions if you don't know how to use them . . .

[shell zephyr]

😔

[cosmic dagger]

watch a quick tutorial on the basics, or at least methods in c# . . .. . .

[shell zephyr]

it literally told me that public and private void where methods ;(

[cosmic dagger]

you need to place a debug log in the same method where you check the speed to ensure that the method is running . . .

[cosmic dagger]

public and private are accessors, and again, void is a return type. i don't think that's what they actually said. if so, i'd be worried. do you have the link?

[queen adder]

In the interest of time, can I assume you meant FixedUpdate(), instead of FixelUpdate()?

[shell zephyr]

Oh, true, didn't notice it!

[shell zephyr]

It's in russian, so i'm not sure you will understand it 👀

[summer stump]

They know c# though

[cosmic dagger]

i see, at least you received your answer. hopefully, it works out . . .

[shell zephyr]

Thank you!
Unfortunately it's a bit confusing to understand it, since it's my first time participating in a game jam as a dev

[queen adder]

You could have also have stuck a debug.log(speed) right before your if statement to see if it was picking up that variable, which I think is what RandomUnityInvader(); was suggesting. The result would have been that that too would not have been printing to the console and given you a better idea to troubleshooting.

Good luck for your game jam.

[snow socket]

Hello, I'm trying to apply the player settings to change the resolution of my build, but it's not changing the resolution. Does anyone know the fix?

[timber tide]

Ususally I force the resolution in my scripts

[frigid sequoia]

Maybe I am freaking dumb, but why is this reference not destroying the stuff?

Like the last one does work

[frigid sequoia]

Oh, wait this IS the refernce sry

[queen adder]

how to stop my player from sticking to walls

[frigid sequoia]

Make the walls have no friction

[queen adder]

yes but then I slide off when i climb on it

[summer stump]

You are probably trying to move INTO the wall every frame. Really need to see the code to answer

[queen adder]

what code exactly?

it happens if I jump and hold right arrow

I want it to just slide along the wall

[summer stump]

The movement code of course

[cosmic dagger]

we need to see your movement code. hard to suggest how to move/slide along a wall if we don't know how you move the character . . .

[queen adder]

ok I thougt u need the collider code too...

public bool isGrounded()
{
    if (Physics2D.BoxCast(transform.position, boxSize, 0, -transform.up, castDistance, GroundLayer))
    {
       
        return true;
        
    }
    else
    {
        return false;
    }
        
}

public void kretnja()
{
    if (Input.GetKey(KeyCode.RightArrow) == true)
    {
        igrac.velocity = new Vector2(speed * 1, igrac.velocity.y);
        
    }

    
    


    if (Input.GetKey(KeyCode.LeftArrow) == true)
    {
        igrac.velocity = new Vector2(-speed *  1, igrac.velocity.y);

    }
    


    if (Input.GetKeyDown(KeyCode.UpArrow) == true && isGrounded())
    {
        igrac.velocity = new Vector2(0, JumpStrength);
        

    }

[queen adder]

yep

[summer stump]

That would certainly be relevant

We don't know what you have of course

[queen adder]

ofcourse I have collider code for that

it wouldnt stick to wall if I didnt

r u trynna make a movement system 3d or fixing?

[queen adder]

wdym

im working on 2d game

[silver girder]

ah so i cant help you in 2d i can help in 3d movement system

is it a top down camera

[queen adder]

no

bro what are u saying

I done that

just let this guy help me

[crimson ibex]

A very newbie doubt. if i have a 3d game, and I want to show a "cell" where 3d spheres can be placed on a plane. Will this "cell" be 3d or 2d gameobject

[silver girder]

well say that

[queen adder]

well read my script

and you will know what I need

[silver girder]

okay

ur character is named igrac?

[queen adder]

yes

[silver girder]

okay

idk im not an expert in 2d i know a bit of 3d

but i can make sfx

[crimson ibex]

not cell . a round circle looking thing. for ui indication

[summer stump]

You are setting constant velicity into the wall. Raycast and check if you CAN move that way, if you can't, don't

[digital vessel]

Hey guys. Which language code is the best for unity?

hi i have a little problem, i have a script for some animation and i have a conflict between jump and fall animation

when i jump the parameter direct switch on fall animation so the jump animation don't work

the jump animation don't have the time to be execute

hey i have a problem in unity bolt visual scripting

#763499475641172029

[silver girder]

i wanna know if the cloth can be put only by itself or does it need a shape to form

[long jacinth]

how do i do this

[silver girder]

i wanna know if the cloth can be put only by itself or does it need a shape to form

[zealous oxide]

hey friends. i've input a system.action into one of my scripts for the first time today. its being invoked when an enemy takes damage. then another script is "listening" to this, in this script https://hastebin.com/share/hewezaguwi.csharp the thing is, when i dont have the justHit bool anywhere in the script, it seems like "enemyHealth.damageTaken += DamageTaken;" gets called about 250/300 times in the space of a second or a frame? i get a huge lag spike. I was under the impression it would have only been called once? [i've added the justHit bool into the script to prevent this from happening but i'm assuming i'm doing something wrong here if the invoke is being called in the other script so much].

[queen adder]

I think you have already been directed to #763499475641172029 channel no?

[silver girder]

that is cloth not visual scripting

[summer stump]

Oh, it was misleading since you said:

hey i have a problem in unity bolt visual scripting

Are you using bolt for the cloth?

[silver girder]

no

i aint using bolt for cloth

i am making it normally

[summer stump]

So is code involved in this at all?

[silver girder]

no

[summer stump]

This is a code channel

[digital vessel]

thank

[silver girder]

ahhhhh sorry sorry

[silver girder]

np

[queen adder]

https://docs.unity3d.com/ScriptReference/MonoBehaviour.Invoke.html Looks like it is expecting a methodname in a string format.
Is your method really TakeDamages(25) or are you attempting to pass through an argument of 25? In which case that is probably why its throwing an error.

[long jacinth]

TakeDamages(Amount) is the function i want to call

[queen adder]

So at the bottom of that link, it says "If you need to pass parameters to your method, consider using Coroutine instead."

[long jacinth]

k thank you

The body of 'Health.OnTriggerStay2D(Collider2D)' cannot be an iterator block because 'void' is not an iterator interface type

i really dont get the problem here

oh i guess i need an ienumerator :(((

private void OnTriggerStay2D(Collider2D other)
{
if(other.tag == "Enemy")
{
TakeDamages(25);
}
}

this is what it normaly does

it instantly kills my player

i dont want to make it on enter

i want it so every 2 seconds it takes damage

[summer stump]

Use a coroutine that cancel when they leave

yield return new WaitForSeconds(2.0)

Coroutine routine = StartCoroutine(TakeDamage(25))

StopCoroutine(routine)

Also cache it so you can do that 👆

[wintry quarry]

OnTriggerStay runs 50 times a second by default

[long jacinth]

ya its still giving me them red lines

[summer stump]

Not a helpful answer

What red lines

What do the errors say?

What did you write?

[summer stump]

Well yeah

That is not right at all

[long jacinth]

i need an ienmuerator right

[summer stump]

An equals sign is required there, and both lines would need semicolons
These errors are just basic syntax errors

And you probably don't want to IMMEDIATELY stop the coroutine

And you are calling TakeDamage and then starting a coroutine called TakeDamage

And I hope you aren't still doing it in OnTriggerStay...

[summer stump]

Lastly, yes, coroutines return IEnumerator

[long jacinth]

i think i got it

still kills me instantly

[summer stump]

You didn't address the issues I said

[long jacinth]

wait should takedamage(25) be before or after the yield

[summer stump]

It is in OnTriggerStay, that is wrong

You are calling TakeDamage directly, that is wrong

[long jacinth]

ohhh

[summer stump]

You are calling StopCoroutine on the line after, that is wrong

Your wait does nothing because TakeDamage isn't a loop, that is wrong

[long jacinth]

what should i replace ontriggerstay2d with

[summer stump]

OnTriggerEnter

[long jacinth]

i still want it to detect triggers

[summer stump]

And StopCoroutine goes in OnTriggerExit

[wintry quarry]

OnTriggerEnter2D <

[summer stump]

Yes, sorry

[queen adder]

Hey, so I'm trying to make a script between the player and a mob that has a 50/50 chance of destroying either of them, but for some reason it's been doing nothing but destroying mobs; am I missing something in my logic here?

[long jacinth]

wait why

[long jacinth]

your random range is a float

[summer stump]

You enter the trigger, it damages you every two seconds until you exit the trigger

Is that not what you want?

[long jacinth]

yea

[wintry quarry]

50/50 chance would be:

if (Random.value > 0.5f)```

[summer stump]

Extremely unlikely to be exactly 0 ever

[glass light]

this has a chance to generate ANY number between 0 and 1. Including any obscure decimal. So you have an infinitely small chance of it being equal to zero

[queen adder]

I see

so all I'd need is this, correct?

I am never using gpt for this kinda stuff again lol

[queen adder]

it works

hell yeah appreciate it, no idea why I didn't realize it was saving their exact values being floating-point numbers lol

[glass light]

chat gpt is a useful tool to give you like an idea for coding, but you shouldnt use it to code. it makes sloppy art, and it also makes sloppy code

[queen adder]

You could use Debug.Log(randomNumber) right after declaration to identify the value.

[glass light]

^, generally debug.log is good for debugging

[long jacinth]

i really am confused

i have never worked with coroutines

[queen adder]

yield return is inducing a 2 second delay until TakeDamages() is called again

25 damage
wait 2 seconds
...

basically

[long jacinth]

ya thats what i want

[summer stump]

Inside the coroutine, you make a while loop. Inside the loop you do whatever TakeDamage did, and then yield return

In OnTriggerEnter2D you do StartCoroutine

In OnTriggerExit2D you stop it

That is it

[long jacinth]

i cant use on triggerstay

[summer stump]

You could but then you'd need to do more work

Really no point in using stay

[long jacinth]

so this is how it should look right

[summer stump]

Closer.
You can't do stopcoroutine line that

And you should validate that it is enemy you are leaving the coroutine of

[wintry quarry]

OnTriggerStay actually could make this pretty simple:

float timer = 0;
float damageInterval = 2;
void OnTriggerEnter2D(Collider2D other) {
  timer = 0;
  DamageThePlayer(); // if you want instant damage
}

void OnTriggerStay2D(Collider2D other) {
  timer += Time.fixedDeltaTime;
  if (timer >= damageInterval) {
    timer -= damageInterval;
    DamageThePlayer();
  }
}```

[mental flower]

So.. to sum it up, my boyfriend is working on creating a 3D racing game in Unity and its going good so far but... we've run into a problem... we can't find the right script for adding a nitrous boost to the car itself (example Need for Speed Heat)... i was hoping someone here could help?

The car does move, and we'd need the script written in C#, with a separate script for the sound and key binding for the booster. (Left shift if anything) Is this the right place to come to?

Someone previously provided a 2D script but we need a 3D script

[summer stump]

Yeah, I was about to say, this was just all based on the coroutine suggestion earlier. There are many ways to do this. Maybe just do what praetor is saying

[mental flower]

maybe getting it transcribed or transferred to be correct..?

[long jacinth]

hmm ok i will try this

[summer stump]

Don't copy paste. Those need to be the 2D variants of the methods

[long jacinth]

ya im figuring it out

WOAH IT WORKS

thanks guys not all heros wear capes fr

Adding zero score isn't going to change the score

any number plus 0 is the same number you started with

[river pecan]

How could I multiply a float every frame and have it framerate independent, I assumed float *= 36 * Time.deltaTime would work but it doesn't

[wintry quarry]

What you have there will work if it runs every frame

but like

why multiply every frame?

That's crazy

don't you want to add?

What ar eyou trying to accomplish

[river pecan]

Multiply velocity from 3 to 0, multiply by 0.6

[wintry quarry]

what?

[river pecan]

(3 * 0.6) * 0.6

Like get the value to lower each frame percentage wise

[wintry quarry]

Can you explain what you are trying to accomplish in gameplay terms?

doing a percentage per frame isn't really sensical

[dreamy urchin]

how can I check in 2D if an object is near an other object, so not if it collides but it has basically an offset to the collider

[river pecan]

So I have a Vector3 that controls velocity, when nothing is pressed, it should go to 0, if I set it to 0 instantly, it feels a little stiff

[wintry quarry]

• Check the distance
  or
• Use a Trigger Collider

[river pecan]

So I want to smooth the stopping

[dreamy urchin]

I think I'll check the distance, I don't want the object to be trigger

[wintry quarry]

Vector3 currentVelocity;
Vector3 targetVelocity;
public float acceleration = 5;

void Update() {
  currentVelocity = Vector3.MoveTowards(currentVelocity, targetVelocity, acceleration * Time.deltaTime);
}```

then you just set targetVelocity elsewhere

yea but i just need it to stop counting when im dead, say if i gain a point every second for being alive and then it stops counting when im dead. any idea how i could write that? am I on the right path or do i have to redo it all?

[wintry quarry]

Adding 0 doesn't mean "stop counting"

it means "add 0"

[wintry quarry]

You could do this at the beginning of the function:

if (!countercomms.birdisAlive) {
  return; // to exit the function
}```

Or just disable the trigger collider

[wintry quarry]

or you could add bird being alive as a condition to the other one:

if (collision.gameObject.layer == 3 && countercomms.birdisAlive ) {
  logic.addScore(1);
}```

That's more so for following right? I'm using a character controller

[wintry quarry]

this has nothing to do with following anything

this is modifying the velocity over time according to your desired velocity

[river pecan]

I'm using a character controller to move

[wintry quarry]

not relevant

[river pecan]

Would they conflict?

[wintry quarry]

would what conflict?

MoveTowards doesn't move anything. It's just math.

Oh
