so battle.GetComponent<BattleStateManager>() is pointless

(unless you have two BattleStateManager components on one object, I guess, but that's very cursed)

[brave compass]

It's undocumented and not intended to be used by users, but it's used by Unity's own packages, such as Timeline. Like other internal APIs, it might be removed or change without notice, but since it's being used by multiple packages spread out over multiple teams within Unity, I think it's unlikely that it will be removed.

[robust harness]

so it should be playerPrefab = battle.playerPrefab;

[swift crag]

oh, I misread your code. I thought you were getting a component from playerPrefab at first

all of those lines are redundant

just write battle.playerPrefab

yeah

You should also change the type of the player prefab from GameObject to whatever component type you'll be using

maybe Player

[robust harness]

thanks

[brave compass]

Examples of usages:

https://github.com/Unity-Technologies/com.unity.probuilder/blob/3b2a761c4e35ddfde58ce088ef4da91c27573a06/Runtime/Core/ProBuilderMeshFunction.cs#L29

Multiple teams would have to coordinate to remove these event methods, which I find unlikely.

[hot laurel]

do you have any examples of using them by user?

[brave compass]

I use it in my project, but it's not open source.
@slender nymph uses it in their Singleton implementation to ensure the instance is set before Awake.

[hot laurel]

nice, thanks, may be usefull in future

Thought it exist for serialization system purpose, but the purpose is more like tooling for lightweight execution before user scripts.

Can someone help? I am trying to make a car game but i think something is going on and my car is going really slow.

Tip #1 is please don't ever make a member variable with a name like "s".

what is s?

strength?

currentStrength?

[burnt vapor]

Please don't comment on code style unless it actually hinders the application

Best is to just help with the issue, then comment on style later to avoid confusion

[edgy tangle]

Well if you want someone else's help, clear naming is pretty crucial.

[burnt vapor]

You can see s is assigned by strengthCoefficient there. It would help more if the code was properly pasted here using a paste site

[edgy tangle]

I admit it's just a pet peeve of mine. Sorry. I'll try to help solve the actual problem.

[hot laurel]

btw the Time.deltaTime is usless in FixedUpdate, its already equal to Time.fixedDeltaTime so the calculation lose its purpose since its static value.

[edgy tangle]

So is the only real issue is that it’s slower than you expect?

[edgy tangle]

That’s not true. It’s just that they are both equal, but either way you need to scale it to the update rate

Although I guess I see what you mean

You can just inherently scale your values down

[hot laurel]

may be it get rid of it and check, the calculations including time delta time are usless but still modify the outcome (fixed delta time its equal to 0.02 by default)

[swift crag]

It's still much more reasonable than just multiplying by 0.02 :p

[eager elm]

it's not useless, it turns the value into 'per second', i.e.:
transform.position += Vector2.right * Time.deltaTime;
would move the object 1 unit to the right every second

[swift crag]

especially given that you can change the physics update rate

[edgy tangle]

Especially because you can change the physics tick rate

Beat me to it

[quick pollen]

how could I turn a float into an angle for a vector3?

that vector3 being a direction

[swift crag]

perhaps you want Quaternion.AngleAxis?

[hot laurel]

thats not the case if its done in fixed update

[swift crag]

This is wrong.

[quick pollen]

dont want to use quaternions here i dont think

[swift crag]

Whether you're in Update or in FixedUpdate, this is bogus:

transform.position += velocity;

You must convert that velocity to a displacement by multiplying by a duration.

[swift crag]

I guess I don't know what you're actually trying to do then

[quick pollen]

the whole thing I want to achieve is
shoot a raycast, turn 10 degrees, shoot a raycast, turn 10 degrees
in a for loop

[timber tide]

If it's 3d you probably shoukd be using Quaternion

[swift crag]

If you want a vector that points in a direction based on an angle, you can do

Quaternion.AngleAxis(angle, Vector3.forward) * Vector3.right;

for example

[polar acorn]

deltaTime in Fixed Update isn't used to make things framerate independent, but it is used to convert values from "per frame" to "per second"

[swift crag]

This spins a world +X vector by angle degrees

around the world +Z axis

[swift crag]

you could also do something like

for (int i = 0; i < 10; ++i) {
  float t = Mathf.InverseLerp(0, 10, i);
  float angle = Mathf.Lerp(0, 360, t);
  Quaternion rot = Quaternion.AngleAxis(angle, Vector3.forward);
  Vector3 dir = rot * transform.up;
}

[edgy tangle]

More specifically, per physics tick.

[swift crag]

indeed

[polar acorn]

Right

[swift crag]

It's true that your game will behave consistently if you leave out the length of the physics timestep

but it will still be wrong

[quick pollen]

Debug.DrawRay(transform.position, Quaternion.AngleAxis(degs[i], Vector3.right).eulerAngles * visionLength, debugColor, _timeBetweenScans);

[swift crag]

It also bricks if you start changing the physics timestep, which is very common when doing slow-motion

[eager elm]

this is an extension method I use to rotate Vectors: https://scriptbin.xyz/zuqaqofaja.cpp

[swift crag]

why is eulerAngles in there?

[quick pollen]

because I need a vector3 and its a quaternion

[swift crag]

well, yes, but that's a completely bogus vector

you're interpreting euler angles as a displacement...

You can multiply a Quaternion by a Vector3 to get a rotated vector

[polar acorn]

You need a direction Vector. Which EulerAngles is not

[quick pollen]

what should I multiply it with?

just vector3.one?

[swift crag]

a direction you want to rotate

[swift crag]

notice what I did here

[quick pollen]

i do not want to rotate anything

I already have all the rotations

[polar acorn]

What direction do you want the ray to point in?

[swift crag]

Yes you do.

Take some starting direction and multiply it with a rotation

Quaternion rot = Quaternion.AngleAxis(90, transform.up);
Vector3 dir = transform.forward;
Vector3 result = rot * dir;

a 3D example

[cosmic dagger]

you said, "turn 10 degrees," which, by definition, is a rotation . . .

[swift crag]

This spins your forward direction around your up axis by 90 degrees

I can never remember if that's clockwise or counterclockwise

[quick pollen]

I have a vector of rotations on the y axis

I want to use those

[polar acorn]

Okay, so, you want to take a direction, and rotate it by 10 degrees about the Y axis

[quick pollen]

I keep fucking up the multiplication

Quaternion.AngleAxis(degs[i], Vector3.right) * Vector3.forward

i dont know which one needs to be which

[swift crag]

Oh, this is a 3D game, right

You need to rotate around the up axis

Quaternion.AngleAxis(degs[i], Vector3.up) * Vector3.forward

This would be appropriate for a 2D game, where the +Z axis is pointing into the screen:

Quaternion.AngleAxis(degs[i], Vector3.forward) * Vector3.up

[quick pollen]

i thought I tried this

ty!

[swift crag]

Rotating around Vector3.right means that you're spinning around the world X axis

[quick pollen]

oh yea this is prolly what I did

[swift crag]

which will spin out of the XZ plane

[quick pollen]

something does seem to be wrong though with my Job

    public struct PFor : IJobParallelFor{
        public float nom;
        public NativeArray<float> results;
        public void Execute(int i){
            results[i] = nom * i;
        }
    }```

this is literally all I do

and its still not good

[swift crag]

presumably nom isn't large enough

if you aren't getting a complete circle

(what on earth is nom)

[quick pollen]

float nominator = 360 / sightPrecision;

[swift crag]

integer division!

💥

[quick pollen]

sighPrecision is the amount of lasers I shoot out

[quick pollen]

FUCK

ur right

forgot to add the f

i swear if it fixes

it does

im so stupid

ty

[hot laurel]

yes its true but that wasnt the case of the question, simply said it scale down input value by factor to fixed update rate.
He didnt want to scale down his moving value, he wanted to move his object faster, and in this case the fixed update was the culprit since it scales down his input value. I dont like unecessary noise, better to focus on the question instead try to push own agenda like others did here

[quick pollen]

okay well I'm not getting more frames

this is sad

[swift crag]

what?

[hot laurel]

noise again

[swift crag]

you provided an objectively wrong answer and everyone else explained why you were objectively wrong

[polar acorn]

If you hate useless noise, then why did you bring up an incorrect irrelevant information to the question

[burnt vapor]

If you don't want noise then stop responding ❓

[quick pollen]

yeah wow its literally not making a single bit of difference, using jobs over normal

[swift crag]

I would not expect that to do very much

[burnt vapor]

Hey but at least you learned more about jobs

[swift crag]

RaycastCommand might help if you can run all of the raycasts in one huge blob

[quick pollen]

for thousands of raycasts and for loops? idk.

[swift crag]

But it's not a massive upgrade, from my experience

It's faster, but not mind-blowingly faster

I use it for a visibility system in my game. I need to shoot lots of rays between entities, as well as work out the light level at each position (so, more rays fired at lights)

[quick pollen]

no, I mean theres literally 0 difference

[rich ice]

literally just clicked on chat. sorry if i miss something. but, you could probably optimise this by doing an overlapSphere first and then raycasting if there's something nearby. you'd probably only need 1 direct raycast (or you can add a few more, that are spread out, for a little more accuracy)

[swift crag]

(also, remove all the debug code when profiling this :p)

Drawing all of the rays is going to be nasty

[quick pollen]

which debug code?

[swift crag]

all those rays you're drawing

[quick pollen]

oh, those are toggle-able

[swift crag]

I wrote a system that collects "light requests" from all over the scene, then executes one big job and passes the results back one frame later

Making this allocation-free was fun

[quick pollen]

well, true, this is my first time using them

idk why im bothering so much tho

this is just a school project

[swift crag]

My bitrate lmao

[quick pollen]

lmao yea

bonkers

[swift crag]

that is absolutely brutal on the encoder

[quick pollen]

how fast is Quaternion.Angleaxis actually?

[swift crag]

It's all very fast math

I guess you could make it even faster, though

[cosmic dagger]

pretty quick . . .

[swift crag]

You could punt all of that into Burst and use the Mathematics structs

[quick pollen]

what I did for the "unoptimized" one is just rotate a gameobject and get it's forward vector

[swift crag]

Okay that's going to be way way worse

[quick pollen]

I did

no difference

[swift crag]

I guess it's not too bad if it has no children

[quick pollen]

literally the same

for some reason

[swift crag]

I would insert some profiler markers to measure how long each step takes

[quick pollen]

like 23 ms

imma send all my code if yall wanna look through it for optimizations

https://pastebin.com/HDk3rvuk

unoptimized one

[rich ice]

honestly, im more interested in the profiler than the code

i gotta know what's going to cause more lag first lmao

[quick pollen]

logging is going to slow you down dramatically

[quick pollen]

didnt know logging strings would be this bad

[rich ice]

nvm x2, that's for commenting

[quick pollen]

xD

[swift crag]

(Also, this "CheckForPlayerJob" method isn't going to get burst-compiled, I'm pretty sure)

especially because it needs to access managed objects, haha

You'll want to use a profiler marker to measure how long the raycasts take vs. how long the raycast command batch takes

[hot laurel]

nah, in his case it was usless use of deltaTime, and it was the culprit of making it slow, the only one irrelevant thing was my response to irrelevant coment of some guy who said "its not usless" well it this case it was

[swift crag]

It is literally wrong to not factor in the length of the physics timestep. If you want your speed to be larger, then you should use a larger speed value.

[quick pollen]

interesting, you can see the yellow/orange part increase whenever I turn off jobs

[swift crag]

rather than randomly ripping out another part of the calculation

[rich ice]

you can shorten this to 1 raycast and an overlap sphere

[quick pollen]

without jobs

something is taking 10 ms inside update both ways

[swift crag]

which you can figure out by using profiler markers, yes...

[quick pollen]

how exactly?

[swift crag]

use Profiler.BeginSample("Foo") and Profiler.EndSample(); to measure a region of code

[quick pollen]

ohh ok

[swift crag]

To be maximally efficient, you can create a marker once and then use it many times

        private static ProfilerMarker _perceptionMarker = new("Perceptions");

e.g.

I use this to profile my perception system

I wrap the relevant code with _perceptionMarker.Begin(); and _perceptionMarker.End();

[quick pollen]

huh.

oh wait I have an idea

could be my Wander script

no

i cant find anything

this makes no sense

wheres the extra 8 ms coming from?

youd think its the timeToLoseSight one

but thats not it

[swift crag]

Anything that isn't being attributed to something else (e.g. to "Foo") is counted in the "Self" time of Update

notice that "Self ms" is 7.78 there

a profiler marker includes any time spend between its start and end that isn't part of another profiler marker

[swift crag]

also, you've got a mismatched begin/end sample on that "Faa" marker

this is going to confuse the profiler

[quick pollen]

as physics go down, scripts go up

[swift crag]

RaycastCommand isn't causing Raycast calls, and those are what count as Physics time

Instead, you're just waiting on a job handle to complete

hence, script time

Insert more profiler markers to make this more clear.

[swift crag]

Uh Oh!

[quick pollen]

huh.

somethings wrong there

this is like 4 lines of code

shouldnt be 20%

[swift crag]

You can get even more granular with it

I have no idea how expensive CompareTag is

[quick pollen]

whats causing it tho?

[quick pollen]

it shouldnt be expensive at all

[swift crag]

Profile it!

[quick pollen]

it uses hashes over string comparations

[swift crag]

so it's hashing the string 6000 times per frame

[rich ice]

cant be that expensive. im pretty sure its basically hte same as string == string

[swift crag]

sounds mildly suspicious

Wrap both if statements in separate markers

This will add some non-trivial cost, but it should at least indicate what's going on

When you do something ten thousand times per frame, even the cheapest of operations can start getting a bit taxing

[quick pollen]

6000*100 yes

[swift crag]

Hits is being measured 60 times per frame, so I presume you have 60 tanks here

shooting 100 rays each

[quick pollen]

btw I am intentionally making the game perform worse, I can change the amount of times I scan for the player

[spare mountain]

i-intentionally?

[swift crag]

they are benchmarking

I've done similar things in my game, like spawning 100 entities that do literally nothing but look at each other

[quick pollen]

huh, tagcompare really is bad

[swift crag]

no brain. no body. no movement.

[quick pollen]

holy

` ` jumpscare

[daring heath]

bad formatted code will fix

[quick pollen]

how else can I check if I'm hitting the player?

[cosmic dagger]

check their component. see which one is worse . . .

[quick pollen]

tagcompare seems to be really angry

[quick pollen]

that sounds 10x worse lmao

[swift crag]

I would normally do this by looking for a component.

[daring heath]

i'm trying to get the first script here to take information from the second script, but the asterisked "AddCollectible" is throwing up a no argument given error. The suggested fix adds the lower lines to the second script. Why isn't it finding the first AddCollectible class in that script?

    {

        for(int i = 0; i < collectibleSlot.Length; i++)
        {
            if(collectibleSlot[i].isFull == false)
            {
                collectibleSlot[i].*AddCollectible*(collectibleName, collectibleSprite);
                return;
            }
        }
    }```
---
```    public void AddCollectible(string collectibleName, string description, Sprite collectibleSprite)
    {
        this.collectibleName = collectibleName;
        this.collectibleSprite = collectibleSprite;
        isFull = true;

        collectibleImage.enabled = true;
        collectibleImage.sprite = collectibleSprite;
    }

    internal void AddCollectible(string collectibleName, Sprite collectibleSprite)
    {
        throw new NotImplementedException();
    }```

[swift crag]

TryGetComponent(out Player player)

You could also filter by layer

If the player is on layer X and the obstacles are on layer Y, that's a very cheap test

[cosmic dagger]

let's profile it!

do you use a filter on your raycast??

[swift crag]

the raycast needs to hit both obstacles and the player

[quick pollen]

no, because there are literally only 2 layers

[cosmic dagger]

too slow . . .

[swift crag]

so there's not much room there

[quick pollen]

yeah

i dont want the tanks to see through walls

but yes, it would be way more efficient

[swift crag]

The layer check would be especially cheap

[cosmic dagger]

i have an idea, but check the player component first . . .

damn you Fen. that was it . . .

[formal hill]

Can anyone explain to me what a Quaternion is/does?

[cosmic dagger]

just check the layer of the hit object. that's just a bit check . . .

[quick pollen]

its a rotation in 3D space

[slender nymph]

https://unity.huh.how/quaternions

[swift crag]

It should have been called Rotation

Alas.

[cosmic dagger]

NonGimbalRotation?

[swift crag]

I don't know how quaternion math really works -- and I don't have to!

I do know most of the vector math I do, but I still don't have to think about it

[edgy prism]

Hello I was wondering about the best way to get real time for time gated events should I be using an API?

[quick pollen]

just as bad, if not worse

its called TagCompare but I used TryGetComponent

[rich ice]

system.dateTime?

[edgy prism]

Thats device time

[cosmic dagger]

now for the big reveal. check the layer . . .

[edgy prism]

I dont want people to be able to change it xD

[swift crag]

if you must have the actual time, get it from a remote source

This will deter basic cheating

[edgy prism]

It concerns me that you say basic cheating is there a more secure way?

[quick pollen]

...how do I do that again?

[swift crag]

the game is running on the player's device, and they could just modify the game to not check the time

[quick pollen]

I cant find the layer

[swift crag]

examine the layer property of the collider you hit

[quick pollen]

o nvm got it

[swift crag]

er

[quick pollen]

cant just get collider

[swift crag]

of the game object of the collider you hit

[cosmic dagger]

it's the layer property . . .

[quick pollen]

its hit.transform.gameObject.layer

[swift crag]

I can never remember which things are on GameObject and which things aren't

You can call TryGetComponent on a component, but not AddComponent

[oak dagger]

It is my issue because it has really slow acceleration, and the top speed based on my calculations should be over 200 kmh but it can only reach up to 105.

[quick pollen]

do I compare number or string?

does it matter?

[edgy prism]

Ohh ok I got you, forgive me if im being annoying but say im a big company and im giving you a daily login reward how would I handle it? Server checks?

[swift crag]

layers are integers

[quick pollen]

if I do == 4 or == "Player"?

[cosmic dagger]

makes sense. you can't add a component to another component because they only exist on GameObjects . . .

[swift crag]

You should compute LayerMask.NameToLayer("Player") once and then reuse that number

[swift crag]

sure, but TryGetComponent implies that components can be attacehd to other components :p

[swift crag]

note that this is not using GetMask, which gives you a bitmask

[cosmic dagger]

if you know the layer, use the int, if not, then convert it using the name of the layer . . .

alternatively, you can compare the bitmask . . .

[slender nymph]

CompareTag on a component just internally calls gameObject.CompareTag, Component.AddComponent could easily do the same thing. In fact you could just make an extension method for it right now

[quick pollen]

its like 4% better @cosmic dagger

[cosmic dagger]

that works for me. it's what i usually do . . .

[quick pollen]

what I find extremely weird is: what I free up in physics processing, I lose in script processing when switching to jobs

[slender nymph]

public static class ComponentExtensions
{
  public static T AddComponent<T>(this Component c) => c.gameObject.AddComponent<T>();
}

they really should have just added the method to the component class, but this is at least an easy workaround

[quick pollen]

im completely confused as to what im losing

[cosmic dagger]

summary makes it look ugly in discord . . .

public static bool TryAddComponent<T>(this Component c, out T comp) where T : Component
{
    if (c.TryGetComponent<T>(out _))
    {
        comp = null;
        return false;
    }

    comp = c.gameObject.AddComponent<T>();
    
    return true;
}

[slender nymph]

lmao even TryGetComponent just calls gameObject.TryGetComponent

[rich ice]

is this still beginner coding...?

[swift crag]

Yes, because the raycast command is not being counted as "Physics"

[quick pollen]

what-

[swift crag]

Your script is waiting on a job to complete

you're calling JobHandle.Complete()

this means "wait until the job is done"

so your script is just parked there, doing nothing.

It does not matter exactly which category the profiler puts this into!

[slender nymph]

probably, extension methods are probably on the beginner side of "intermediate" knowledge about c#. it's some handy stuff to know about tbh
unless you're referring to all the raycast command stuff lol

[quick pollen]

I could get rid of a jobhandle by doing simple maths

instead of all this bs

just i * nominator

[swift crag]

I'm talking about the raycast command.

If you can't wait for a bit before using the results of the command, then it's not going to be that much better than just running the raycasts directly

[swift crag]

This should happen entirely on your servers

the player should not be able to say "It's time for my reward!" and just get the reward

[swift crag]

How are you figuring that?

[cosmic dagger]

oh, MentallyStable posted your implementation of Singleton using internal Awake. i noticed an error in the getter. you forgot to assign _instance before returning it

not sure if it was fixed as this may be old code . . .

[quick pollen]

so I fiddled around with my optimizational features a bit, turned down precision, increased the time between checks....

those spikes are the comparetags....

[swift crag]

Consider smearing out the queries over time

Chop the tanks into ten groups and run one group per frame

That is how I handle vision in my game. I break entities into five groups and round-robin them

[quick pollen]

....wdym?

I am checking if the object im hitting is a player

[slender nymph]

don't need to. __internalAwake runs before AddComponent returns so _instance is already assigned by that point

[swift crag]

I'm saying to not check all 60 tanks every single frame.

[oak dagger]

Because i have a different code that makes it able for me to see the speed i am going (it is a really simple speedometer) and the results i get are not the ones that they were supposed to be

[rich ice]

what are you testing anyway? the code? raycasts? your pc?

[swift crag]

I'm asking you why you think you should be going at 200 km/h

[quick pollen]

the thing I did there is make it so it only launches all the raycasts every x seconds

[swift crag]

Right. You're having every single tank run a query once every x seconds.

Hence the enormous spikes

[quick pollen]

i dont know how to smear them

[swift crag]

a very simple way:

[quick pollen]

like the problem is that they're synced

they all check for the player at the same time

[swift crag]

int val = GetInstanceID() % 10;

if (Time.frameCount % 10 == val)
  Whatever();

[quick pollen]

I need to somehow stop that from happening

[quick pollen]

whu

I mean I get what it does

but whu

[swift crag]

this makes Whatever() execute once every ten frames

and the exact choice of frame depends on your instance ID

[cosmic dagger]

can't you use a random seed for each unit?

[quick pollen]

thats basically what fen does

a bit more efficient maybe

[cosmic dagger]

oh, yeah. that's nice . . .

[swift crag]

this would also be very reasonable (and I can't remember if instance IDs can be any number or not, actually)

[edgy prism]

Thankyou for your help! Step one go get some servers I guess

[swift crag]

i.e. maybe they're all divisble by 2

i forgor

[rich ice]

im still pretty sure that the issue is the absurd amount of raycasts

[quick pollen]

this looks abyssmal

[rich ice]

surely you can just optimize that to a single raycast

[swift crag]

In practice, yes, you would just fire a few rays directly at the player

[rich adder]

btw if all you need is daily rewards , server system functions too . unity already has that covered in the basic free tier via UGS / Unity Cloud
eg https://docs.unity.com/ugs/en-us/solutions/manual/DailyRewards

[quick pollen]

right now I'm benchmarking with 100 raycasts, normally id only use like 20

and not 20 tanks, but like 5 or 10

not to mention I wouldnt be checking for the player every frame, rather once every second or so

[languid spire]

bear in mind, most instanceID's are negative so you probably want to check an Abs into the mix

[quick pollen]

LMAO I was wondering why my frames skyrocketed, turns out I nuked my raycasts xd

[rich adder]

with this many casts you should consider using Raycast command and batch them

[quick pollen]

doesnt really work

        int val = GetInstanceID() % 10;
        if (timeBetweenScans > 0f)
            timeBetweenScans -= Time.deltaTime;
        else if (job)
            if(Time.frameCount % 10 == val)
                CheckForPlayerJob();
        else CheckForPlayer();```

[quick pollen]

I already am :>

[rich adder]

oh lol

[swift crag]

ah, yeah, good point -- % is the remainder operator, not the modulus operator, so it spits out negative numbers there

[quick pollen]

oh

[swift crag]

(please just give us the modulus. nobody ever wants a remainder)

[cosmic dagger]

yeah, just the ones created during runtime . . .

[swift crag]

x -= 1;
x += n;
x %= n;

[quick pollen]

isnt modulus just absolute value?

[oak dagger]

Because i have did some testing with the unity standard assets car and the result was for a car that was 2500 kg that was going at 200 kmh, so because my car is 1000 kg and will have around half the power, i suppose it will reach 200 kmh. There is possibility that the wheel colliders are the issue but I am not sure about that

[polar acorn]

No, it's modulus

[swift crag]

No, it's a value y such that x = kn + y

[polar acorn]

https://en.wikipedia.org/wiki/Modulo

[swift crag]

where k is an arbitrary integer

In mathematics, the result of the modulo operation is an equivalence class, and any member of the class may be chosen as representative; however, the usual representative is the least positive residue

this is what I always want

[quick pollen]

ah right, my bad
in romanian we have the same word but for absolute values

[edgy prism]

Wow thankyou this is incredible, I was actually trying my hand at daily missions but Im sure I will also add rewards at one point too so this will be very useful

[quick pollen]

@swift crag i would love to post the result but i think itd get blocked for causing epileptic seizures

sike

also this boosted my fps quite well, tho im not sure if its because of the smearing or because im not running the raycasts every frame

[swift crag]

well, yes, the smearing is why you aren't running so many raycasts every frame :p

[quick pollen]

well no

well ok yes

technically

it matters less when I decrease the check times

it goes from one large spike to multiple smaller ones

[cosmic dagger]

it looks good. i like to run any raycasts or distance checks based on x times per second or every x frames. most of the time, you don't need to do it every frame . . .

[swift crag]

You can do better than that -- you could spread the raycasts out over all frames

[quick pollen]

im guessing you mean x times per second

[swift crag]

right now, you're only doing tests about half of the time

[quick pollen]

x times per frame sound insane

[quick pollen]

thats what im trying actually

[cosmic dagger]

oh, i meant every x amount of frames . . . 😅

[quick pollen]

there we goo

much better

o wait

no

i changed it to % 20

maybe its better

int val = Mathf.Abs(GetInstanceID()) % (int)(1.0f / Time.deltaTime);

ill try something like this

actually this might be a stupid idea

i wanted it to be based on framerate

[vestal sandal]

hi guys

[swift crag]

You can use Time.realtimeSinceStartup to get the exact time (rather than the "in-game" time). This could be used to limit how much time is spent on queries per frame

for example, you can limit it to 5ms of work per frame

[quick pollen]

i... dont understand

im literally just playing firework simulator

70 fps if i turn off gizmos

that was actually a pretty good recommendation tho @swift crag so ty!

it feels like I have vsync on

it just wont go over 60 fps no matter what

even tho I have the targetframerate as -1

[true owl]

are these conditions for the transition an "and" or an "or"

like && or ||

[quick pollen]

and

[rich adder]

&&

[true owl]

thx

[quick pollen]

you want 2 transitions for it to be an or

[true owl]

ah

gotcha

[oak dagger]

Could it possibly be an issue with how the wheel colliders are setup and not with the code? I ask because i think the wheel colliders are slipping too much and that could be the reason why the car cannot speed up

[swift crag]

Yeah, if the wheels are slipping, then you won't be getting any torque

A slipping wheel does almost nothing

[true owl]

so this means it's an or

just confirming

[quick pollen]

yeah

[swift crag]

You have two transitions between "Ground States" and "Air States"

[true owl]

sweet

[swift crag]

If either transition succeeds, you'll switch states

[true owl]

cool cool

thx

[swift crag]

so yeah -- many transitions for "or", one transition for "and"

[quick pollen]

ngl

i wish they just added an or

[oak dagger]

How can I fix that?

[quick pollen]

instead of having to copy over all the fucking settings

[swift crag]

in real life: more weight, more downforce, or more friction between the tires and the road

not sure how many of those translate into Unity physics...

[swift crag]

yeah, some basic compound conditions would be nice...

I've done some awful stuff in VRChat

[quick pollen]

what does that have to do with unity

xD

[rich adder]

VRChat is made in unity

[swift crag]

VRChat is a Unity game.

[quick pollen]

I know, I was making a stupid joke

[swift crag]

Almost everything you do with avatars is Animator-based

it's great

[quick pollen]

btw I think im done optimizing for today, its all i did all day

but ngl it was fun

[oak dagger]

I have tried to change the box collider of the car and made it a little lower and that helped a bit but not enough and i have also changed both the forward and sideways stiffness on the wheel colliders but it didn't really help and it made the car shake a lot when i was going over 50 kmh

[quick pollen]

more fun than working on my main game for now

but at least I know how I'll be adding pathfinding to my bosses

although the way the movement works for navagents kinda sucks, I hope I can just somehow use the pathing or smth without the movement, maybe make an invisible agent that the boss follows

[rich adder]

you dont technically have to use the A* pathing , you can just use the navmesh without

good way to have chars move freely on a floor without dealing with walls

[swift crag]

You can make queries directly, yes

[quick pollen]

also, yeah, why is it that the game has the same fps with 20 tanks as with 200

[quick pollen]

I guess I'll have to figure that one out later

[swift crag]

You can also make the agent not control the position of its object

(you can't stop it from rotating the object, though..)

[quick pollen]

for this school project it works fine

[swift crag]

in the past, I've parented an empty to my character with an Agent on it

[quick pollen]

but for my game, ill want something better

[quick pollen]

thats what I thought about too

[swift crag]

well, to be more precise: you can turn off the updateRotation property, but the agent still messes with your rotation. IIRC it stops it from tilting up or down

[rich adder]

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/AI.NavMeshAgent.Move

[edgy tangle]

That definitely sounds like an issue if the friction of the wheels is supposed to be the force moving the car like in real life

It’s analogous to wheels spinning in mud — no traction, no velocity

[oak dagger]

How can I fix that though?

[edgy tangle]

Personally I would not pursue that level of realism and instead would figure out a way to fake it… that level of detail and realism is beyond my understanding of how to use the physics system

Maybe this can help

[faint osprey]

so ive got a bunch of animations for walking for my character which ive made and it now looks like its walking only thing is now ive got a gun sprite to include in the walking so how would i add that to the walking animations do i have to get the artists to make seperate animations for walking with each gun or am i missing something

[quick pollen]

just... attach the gun to his hand?

[upper forge]

So im trying to get my player to climb a walk and i am using a raycast and i have the raycast position as a empty gameobject on the player so when the player is facing right and then left the empy gamobject follows, the climb works for the right but when player is on the left they dont climb up?

Im confused

[astral falcon]

So are we without any code

[quick pollen]

u sure the raycast isnt hitting the player when going to the left?

[cosmic dagger]

need code to see how your raycast works . . .

[upper forge]

RaycastHit2D hitRight = Physics2D.Raycast(rayCastPos.transform.position, rightRayDirection, 2f, SuctionCupLayer);

RaycastHit2D hitLeft = Physics2D.Raycast(rayCastPos.transform.position, leftRayDirection, 2f, SuctionCupLayer);

anim.SetBool("isClimbing", hitRight);

anim.SetBool("isClimbing", hitLeft);

public GameObject rayCastPos;
public Vector2 rightRayDirection = new Vector2(1, 0);
public LayerMask SuctionCupLayer;
public Vector2 leftRayDirection = new Vector2(-1, 0);

[quick pollen]

ah

so you set isClimbing to hitRight, then you set it to hitLeft

[faint osprey]

then its just a floating gun near its hand it doesnt look like its holding it

[quick pollen]

that means that no matter what value hitRight has, isClimbing will always get overwritten by hitLeft due to syntax

[quick pollen]

i dont get how this is a programming question tho
i can help with figuring out animations but not here

#🏃┃animation and post me some vid and/or screenshots

[cosmic dagger]

you should only set isClimbing to right when you're climbing right. the same applies to climbing left . . .

[upper forge]

I thought thats what i was doing...
Could you explain a little more on how id do that please

[upper forge]

how would i fix that?

[astral falcon]

Is your raycastPos flipping with your character when looking left?

[upper forge]

Yes thats why im confused

[cosmic dagger]

right now your code sets isClimbing to hitRight, then it sets it to hitLeft in the very next line. you are overriding it when you are climbing to the right . . .

[quick pollen]

what you do currently, is set the value of isClimbing to hitRight, which is either true or false, and then immediately set the value of isClimbing to hitLeft, which is also true or false
that means, that if hitRight was true and hitLeft is false, isClimbing will be false

same thing happens vice versa, and inverted. doesnt matter what value hitRight has because hitLeft is the last value that you set it to

[cosmic dagger]

you should check which direction you're facing and place the raycast code for that direction in the if statement, and the opposite direction in the else . . .

[astral falcon]

or just setboolean to hitLeft || hitRight

[upper forge]

 anim.SetBool("isClimbing", hitLeft || hitRight);

?

[upper forge]

how do i get facingdirection?

[true owl]

is there a way to make it so that if my player is holding W and D for example, he doesn't get the speed of that and still continues his speed as if he was holding D only?

[slender nymph]

normalize the input before mulitplying by the movement speed

or clamp the magnitude if you want to support analog input less than a length of 1

[astral falcon]

yes, if you want it to be true for one of both, you can just check if either or one is true, if none, its false.

[true owl]

I did that but I don't think it works

void OnMove(InputValue value)
    {
        moveInput = value.Get<Vector2>().normalized;
    }

[slender nymph]

show how you are actually using this, because digital input should already be normalized if you're using the input system and didn't explicitly select the non-normalized Vector2 composite

[true owl]

    // Handles player movement velocity
    void Move()
    {
        if (!isDashing)
        {
            rb.linearVelocity = new Vector2(moveInput.x * playerSpeed, rb.linearVelocity.y);
        }
        animator.SetBool("isRunning", true);
    }

oh wait

this code is confusing

actually nvm

i think its fine

[slender nymph]

ah, so in that case you don't want to normalize the input if you're only using a single axis

[true owl]

wym by a single axis, just the X in this case?

here's my full code maybe something is wrong

https://paste.mod.gg/pplptxzgcpbn/0

[pseudo ermine]

Hey - are there many tutorials / documents that would be helpful for changing/accommodating to unity 6?

[true owl]

if u wanna look

if you don't no pressure

[slender nymph]

yes, you're only using the X axis. this is not a code thing, you need to adjust the input action asset

[true owl]

the input manager? What if I want to keep it later on for usage for my dash (which i want to go diagonally)

[rich ice]

no :D

there probably are. but, the changes aren't that big

well they are, but not for the average user

[upper forge]

When i did that this happens

[rich ice]

basically, just check the change logs if you want to see all the differences. explore and find out while using unity 6, if you're unsure of whats new

also not a code question

[pseudo ermine]

Apologies.

[slender nymph]

not the input manager because that's not even what you are using. i was referring to the input action asset that you are using for input.
of course if you want diagonal movement then you'll need to normalize that, but also why have vertical input only for the dash?

[true owl]

well its like

i want them to be able to dash diagonally

but when you're on the ground i dont want holding diagonally to affect it

the run that is

[astral falcon]

you maybe should use debug.drawline to show, where you are raycasting against and maybe drawsphere to get the hitpoint

[oak dagger]

Is the speed value on a rigidbody measured in m/s?

[swift crag]

By default, one world-unit is one meter, so yeah

[oak dagger]

This means that i had my speedometer set wrong. Now that i fixed it i can reach the speed i wanted

The good thing is now i know that my code is working as it should and i can finally start working on stabilizing the car at high speeds and make the tire meshes follow the suspension

[true owl]

i figured it out

idk if this is a good soln but

[gloomy cosmos]

Hello, when emitting particles through script is there any easy way to set startindex to use on spritesheet? I need to set which sprite to use on any particle.

[true owl]

    // Handles player movement velocity
    void Move()
    {
        if (!isDashing)
        {

            float adjustedMoveInput = isGrounded || isOnRail ? (moveInput.x == 0 ? 0 : (moveInput.x > 0 ? 1 : -1)) : moveInput.x;
            // if player is on ground or rail, have holding diagonally affect the same as just horizontally 
            rb.linearVelocity = new Vector2(adjustedMoveInput * playerSpeed, rb.linearVelocity.y);
        }

        animator.SetBool("isRunning", true);
    }

lol excuse the code haha

[slender nymph]

if you want to still use the Vector2 input from the input action asset, just get the Mathf.Sign of the x axis instead of nesting ternary operations

[true owl]

oooh

that's way better

thx

[upper forge]

AHH okay so they raycast line isnt actually facing the left... doy ou know how i would fix this? or get the players facing direction?

[astral falcon]

I mean, for your game, it looks like Vector3.left will always be correct, as your world isnt changing, right?

[upper forge]

No cause the player can go left or right. Unless im not understanding what your saying

[astral falcon]

I mean, left for your player will always be left of your world?

[upper forge]

yes i believe so

[astral falcon]

So you could just raycast into Vector3.left and .right

[upper forge]

 RaycastHit2D hitRight = Physics2D.Raycast(rayCastPos.transform.position, Vector3.right, 2f, SuctionCupLayer);

 RaycastHit2D hitLeft = Physics2D.Raycast(rayCastPos.transform.position, Vector3.left, 2f, SuctionCupLayer);

 anim.SetBool("isClimbing", hitLeft || hitRight);

So i did this and is still doing same thing in video and the raycast line still isnt switching to the left when player is facing left

[gloomy cosmos]

hello, still trying to do the unique sprite per particle. One solution I thought of was giving particles a very long lifetime and setting up a curve in the texture sheet animation, but this doesn't seem to work, this is the code:

// There are 17 sprites
particle.remainingLifetime = 9000 + ((i % 17) / 17f) * 1000;
particle.startLifetime = 10000;

I made the curve go from 0 at time 0 to 1 at 0.1, which is 10% of the lifetime, Yet this does not work, all bullets seemingly only depend on the value at zero.

[astral falcon]

where is the line draw code?

[forest summit]

I have this pick up script from a video i followed, and for some reason the hold pos wont move with the character itself

heres the code

Is this correct?

[forest summit]

it wouldnt let me it was too large

[rich ice]

if only large codeblocks was a listed option

[upper forge]

@astral falcon

[swift crag]

this always draws a ray in the world -X direction

[rich adder]

you assume people read..

[swift crag]

no matter what direction you're facing

[forest summit]

yeah thats my bad

[upper forge]

how owuld i fix this?

[swift crag]

don't do that!

presumably you want to use the same directions you used in the raycasts

[upper forge]

RaycastHit2D hitRight = Physics2D.Raycast(rayCastPos.transform.position, Vector3.right, 2f, SuctionCupLayer);

RaycastHit2D hitLeft = Physics2D.Raycast(rayCastPos.transform.position, Vector3.left, 2f, SuctionCupLayer);

but im just useing Vector3.right and Vector3.left..

[swift crag]

don't you want to draw a ray in both directions, then?

[polar acorn]

Remember that DrawRay does not have a "distance" parameter. You'll need to multiply the direction vector by the length

[upper forge]

Debug.DrawRay(rayCastPos.transform.position, Vector3.right, Color.black);
Debug.DrawRay(rayCastPos.transform.position, Vector3.left, Color.black);

So this ?

[swift crag]

This will draw two rays

If you give them a length of 2, they'll correspond to the raycasts you're doing

[true owl]

can someone explain to me why I need both a tilemap collider 2d and a composite collider 2d?

[swift crag]

TilemapCollider2D is used to produce a collider out of your tilemap.

CompositeCollider2D glues multiple colliders together.

[true owl]

got it

[swift crag]

I don't see why you'd need one if you only have that single tilemap collider

Although, it may change the precise shape of the collider

[true owl]

i was just wondering what the diff is

i like both because it lets it smooth out

but the issue is

I got this code to do a one way platform

 void Update()
    {

        // checking if holding down, this disables the collision of the platform,
        // allowing for the player to drop down
        if (moveInput.y < 0)
        {
            Debug.Log("Holding down...");
            if (currentOneWayPlatform)
            {
                StartCoroutine(DisableCollision());
            }
        }
    }

    void OnMove(InputValue value)
    {
        moveInput = value.Get<Vector2>().normalized;
    }

    private void OnCollisionEnter2D(Collider2D collider)
    {
        if (collider.gameObject.CompareTag(ScStrings.railLayer))
        {
            currentOneWayPlatform = collider.gameObject;
        }
    }
    private void OnCollisionExit2D(Collider2D collider)
    {
        if (collider.gameObject.CompareTag(ScStrings.railLayer))
        {
            currentOneWayPlatform = null;
        }

    }

    private IEnumerator DisableCollision()
    {
        CompositeCollider2D platformCollider = currentOneWayPlatform.GetComponent<CompositeCollider2D>();
        TilemapCollider2D tilemapCollider = currentOneWayPlatform.GetComponent<TilemapCollider2D>();

        Physics2D.IgnoreCollision(playerCollider, platformCollider);
        Physics2D.IgnoreCollision(playerCollider, tilemapCollider);
        yield return new WaitForSeconds(2f);
        Physics2D.IgnoreCollision(playerCollider, platformCollider, false);
        Physics2D.IgnoreCollision(playerCollider, tilemapCollider, false);
    }

he can't drop down though

nvm the issue is

the current oen way platform is null

seems OnCollisionEnter2D isnt working

[slender nymph]

https://unity.huh.how/physics-messages

[polar acorn]

The Three Commandments of OnCollisionEnter2D:

1. Thou Shalt have a 2D Collider on each object
2. Thou Shalt not tick isTrigger on either of them
3. Thou Shalt be moving via a 2D Rigidbody on at least one of them

[grand snow]

4. ???
5. Profit

[true owl]

is it possible it's not working cause my rigidbody on the platform is static?

[polar acorn]

Is the other object moving via rigidbody?

[true owl]

no

only my player is moving

[grand snow]

its void OnCollisionEnter2D(Collision2D collision) btw, the argument type is wrong

[polar acorn]

Then condition 3 is not met

[true owl]

oh

[polar acorn]

Oh, also that

[polar acorn]

Does the player have a rigidbody

[grand snow]

only trigger events have Collider as the arg type

[true owl]

yes

[slender nymph]

that would produce an error in the console though so if that isn't even appearing then they need to address the other stuff first

[polar acorn]

Is it an error or a warning?

I haven't run in to it in a while

[grand snow]

huh wasn't aware it did but they can fix it up along with the other stuff i guess

[true owl]

the platform has all of this
the player has the stuff in 2nd image

[slender nymph]

you know, i can't remember either. but it would be something in the console at least

[true owl]

i want him to drop down the platform when holding S

[polar acorn]

Okay, and are you moving the object via rigidbody

As opposed to transform, for example

[true owl]

yes I'm using rb.linearVelocity

[polar acorn]

Okay, so that's fine then, fix the parameter and it should be working

[true owl]

I really feel like it's definitely the

TilemapCollider2D

is messing with things

[true owl]

I did but still no dice

[polar acorn]

Show the updated code

[slender nymph]

have you gone through the link i sent?

[true owl]

i took a look at it

i'll reread it

here's the updated code

public class PlayerOneWayPlatform : MonoBehaviour
{

    private GameObject currentOneWayPlatform;
    [SerializeField] private CapsuleCollider2D playerCollider;

    // Start is called once before the first execution of Update after the MonoBehaviour is created
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
        Debug.Log(currentOneWayPlatform);
        // checking if holding down, this disables the collision of the platform,
        // allowing for the player to drop down
        if (moveInput.y < 0)
        {
            Debug.Log("Holding down...");
            if (currentOneWayPlatform)
            {
                StartCoroutine(DisableCollision());
            }
        }
    }

    void OnMove(InputValue value)
    {
        moveInput = value.Get<Vector2>().normalized;
    }

    private void OnCollisionEnter2D(Collision2D collider)
    {
        if (collider.gameObject.CompareTag(ScStrings.railLayer))
        {

            currentOneWayPlatform = collider.gameObject;
        }
    }

    {
        if (collider.gameObject.CompareTag(ScStrings.railLayer))

        Physics2D.IgnoreCollision(playerCollider, platformCollider, false);
        Physics2D.IgnoreCollision(playerCollider, tilemapCollider, false);
    }
}

the player code is pasted above

https://paste.mod.gg/pplptxzgcpbn/0

its a tiny bit outdated but the movement is still the same so

[polar acorn]

Try logging collider.gameObject.tag before the if

And see what it logs when you hit the platform

[true owl]

in the update method?

oh nvm

im dumb

it logs "Rail"

WAIT

it works

it's just the first time he drops

the collider doesn't trigger for some reason

[polar acorn]

Okay, and if it doesn't log "here", then that means that ScStrings.railLayer is not "Rail"

[true owl]

um sorry

it works

thank you all

[polar acorn]

As is, whenever you stop colliding with any object with the tag Rail, it gets set to null. Even if you are still in contact with another rail

[slender nymph]

so it sounds like you just need to pay better attention to the console if changing the method parameter was all you needed to do

[real falcon]

the ragdoll creator wants the character in a T pose but idk how to make it do that in the editor

I have a tpose clip and I made it the default state in the animation controller

[slender nymph]

this is a code channel

[real falcon]

I dont see a ragdoll channel

[slender nymph]

maybe give #🔎┃find-a-channel a read

[real falcon]

is there a help channel

[slender nymph]

maybe give #🔎┃find-a-channel a read

[real falcon]

ok so ill go to physics and someone will say this isnt a physics question

[slender nymph]

have you considered giving #🔎┃find-a-channel a read?

[real falcon]

so ill go to animation and someone will say this isnt an animation question

[slender nymph]

i bet it can tell you where to ask your question

or you could just keep ignoring the suggestion and get bounced around the discord as you keep putting your question(s) in the wrong channels

[real falcon]

when I ask in unity talk people say this isnt a help channel

[polar acorn]

No one has said that

[real falcon]

ill just figure it out myself, cant be bothered to navigate the 5 million rules large discords always have

impossible to ever do something in a way that doesn't make a mod angry

[slender nymph]

okay bye then

[true owl]

what does that mean

[polar acorn]

Right now, whenever you start colliding with a Rail, you set currentOneWayPlatform. Whenever you stop colliding with a Rail, you un-set currentOneWayPlatform

Now, what do you think happens if you're standing on two different rails, and then step off of one

[true owl]

how can i stand on two diff rails

[slender nymph]

either keep a list of the ones you are currently in contact with or just use a physics query when you need to know if you are in contact with any

[true owl]

No i meant, when would the case be when I'm standing on two rails

[slender nymph]

the first option would have you add/remove them in CollisionEnter/Exit, the second is more versatile because you only check if you are in contact with one when you need that information

[polar acorn]

Well, you can pass through them, so what if there were two on top of each other

And you are passing through one

[true owl]

I don't think I will have that case

In my game

[slender nymph]

you may not think you will experience that, but what if you do. design your systems better and you won't have to track down weird bugs that you may introduce due to poor design

[true owl]

but regardless for learning purposes what is a physics query

sure

[slender nymph]

like a raycast or overlapcircle, they query the current state of the physics engine to check for colliders in different shapes/directions.

[true owl]

I might have to watch a video on that or something

Don't know what those are

[static cedar]

I kinda prefer to have OnEnabled run after start?

[swift crag]

OnEnabled runs when the behaviour is enabled, not a while later

that would be a bit odd

[teal viper]

I prefer to have a salary of million dollars. Sadly, that's not the reality

[static cedar]

Sad.
Are you willing to become the EA CEO though?

[polar acorn]

Then you should stop preferring that

[rich ice]

they haven't made enough scummy lootboxes for that job position

[teal viper]

Are you offering the position?🤔

[static cedar]

Nah, I was wondering how far you'd go for the 1 million salary.

[barren prawn]

To be the CEO?

[cosmic dagger]

but wouldn't you need to enable something in order to start it?

[static cedar]

I thought you'd use Start for another step to initialise. And it's only run once.
But I guess I'm fine as long as it doesn't run on frame 0/right after Awake.

[slender nymph]

you typically would use Start for more setup/initialization but the order of operations is Awake -> OnEnable -> Start, it is possible all of this runs on the first frame, but Start may not be called until the next frame depending on when the object was instantiated

[static cedar]

Thinking about it.
What exactly happens if a game object is disabled and reenabled on the same frame?

[polar acorn]

The object will be disabled, then enabled

[rich ice]

if there's no code in-between, nothing

[west radish]

I think I know what you're getting at. As in if you wrote

void Update() {
this.SetActive(false); // this means this game object has disabled itself
this.SetActive(true); // but as it is now inactive, how could it get here to re-activate itself?

[polar acorn]

Deactivating an object does not return from the current function

[crisp olive]

i don't think this is the code acting up but who knows.. i get this weird trailing effect, anyone know how to fix it?

[rich ice]

camera background is set to unitialized instead of background or solid colour

might be different depending on your RP

[crisp olive]

i cant find those setting but i did figure it out, Clear Flags was set to Don't clear

thanks for the help though

[swift crag]

yes -- Unity has very little power over what code actually runs

you can run methods on disabled behaviours...or even on destroyed objects!

[crisp olive]

i hate to ask 2 questions in one day but i really wanted to get this to work tonight..how would i go about rotating the top piece? i'm trying to, when Z key is pressed rotate Z axis in increments of 120

[ivory bobcat]

What have you tried?

There's no limitation on questions btw

[crisp olive]

but i wanted a cool little visual like if this object was a pyraminx rubik's cube and i was twitsting the top into the next available position

[teal viper]

There's no limitation, but you have to pay $10 for each extra question

[teal viper]

Share the code.

[crisp olive]

aye if that was a thing i'd gladly do it

something like this but i want it to stay locked into a location in increments of 120 using UnityEngine;

public class TopZ : MonoBehaviour
{
public float rotationSpeed = 30f;

void Update()
{
    
    Vector3 currentRotation = transform.rotation.eulerAngles;

    float newZRotation = currentRotation.z + rotationSpeed * Time.deltaTime;

    transform.rotation = Quaternion.Euler(currentRotation.x, currentRotation.y, newZRotation);
}

}

[ivory bobcat]

if z was pressed
    start coroutine: rotate z```

[static cedar]

Nah, I was talking about how it would affect OnEnabled and OnDisable.

[crisp olive]

still doesnt work i guess i'll try again some other time or skip that

[static cedar]

Once a function is called, it only returns on return or function end.

There's no way to stop a function before that.

[crisp olive]

its a 3d object so i wanted the player to see that the game was 3d instead of it exploding into 120 in a split second haha

they tell you to make a simple game to learn and i made it more complex than it needs to be

[sour snow]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEditor;
using Photon.Pun;


public class Portal : MonoBehaviourPunCallbacks
{
    public Transform Destination;
    public Transform Player;


    public string Tag = "Player";

    public float waitTime = 1;

    public override void OnConnected()
    {
        base.OnConnected();

        if(PhotonNetwork.IsConnected)
        {
            GameObject existingPlayer = GameObject.FindGameObjectWithTag(Tag);

            if (existingPlayer != null)
            {
                Player = existingPlayer.transform;
            }
        }
    }


    private void OnTriggerEnter(Collider other)
    {
        if (other.CompareTag(Tag))
        {
            StartCoroutine(waitTillTeleport());
        }
    }

    IEnumerator waitTillTeleport()
    {
        yield return new WaitForSeconds(waitTime);

        CharacterController controller = Player.GetComponent<CharacterController>();

        if (controller != null)
        {
            controller.enabled = false;
            Player.position = Destination.transform.position;
            controller.enabled = true;
        }
        else
        {
            Player.position = Destination.transform.position;
        }
    }
}```



shouldnt it have the existingPlayer transform equal the Player transform this is whats confusing for me since i just started using photon pun
i dont know if any of you use it but its probably simple but its confusing for me

ok

[mystic lark]

how do i make a object make a clone every second or so 100 times or until i tell it to stop i just dont get it i tried using courotines but it doenst work anyone help?

[slender nymph]

your coroutine did not have any loop in it so it would run a single time then end

but the answer is either use a coroutine with a loop or a timer in update

[wintry quarry]

A coroutine will work fine, or just some logic with a timer in Update and counter

[mystic lark]

k ill try

[mystic lark]

but also it shuld of then made atleast one clone but it didnt

[slender nymph]

then you probably didn't start it correctly

[mystic lark]

see this is what i did but it doesnt even debug anything nether does it spawn a clone but when i put the INstatiatiate in start it works fine

and i aslo get this eroer

[slender nymph]

well that would be why the coroutine never starts. exceptions stop execution of the method they occur in

[wintry quarry]

You never assinged that variable

[slender nymph]

also you definitely don't want to be starting that coroutine in update like that, otherwise you'll end up with way too many instances of it starting

[mystic lark]

k but how then

[mystic lark]

what variable

[wintry quarry]

the one you're dereferencing on line 20

like the error says

scoreNewScore

[mystic lark]

oh thats were i can see the line i didnt know that

ty

[wintry quarry]

yes the error says the line number and filename

[slender nymph]

you should give this information a read: https://unity.huh.how/runtime-exceptions/nullreferenceexception

[mystic lark]

ok

[slender nymph]

also since you just want this to start after a certain condition is met then continue possibly indefinitely, just use a timer in update. it will be a bit simpler to manage than a coroutine

[mystic lark]

il try but i am kinda very new with C# and unity making a timer will be hard is there any tutorial u suggest?

[wintry quarry]

a timer is very easy

[slender nymph]

just google "unity update timer"

[wintry quarry]

something like this:

float timer = 0;
float interval = 1; // 1 second

void Update() {
  timer += Time.deltaTime;
  if (timer >= interval) {
     timer -= interval;

     SpawnSomething();
  }
}```

[mystic lark]

i still have no idea what time.delta time is lol

thanks

[wintry quarry]

it's the amount of time that passed since last frame

that's it

nothing special

by adding that number we're just counting up our timer

that makes a simple timer

timer += the amount of time that has passed

that's all that's happening

[mystic lark]

oh i understand now it is quite simple

[wintry quarry]

for example if the previous frame was 1/10th of a second ago, Time.deltaTime is 1/10 or 0.1

[wintry quarry]

yep - people overthink it

[versed light]

this might seem like an odd question but does unity gizmos/handles for spheres and discs use signed distance fields to render them or does it generate a mesh

[wintry quarry]

Probably neither - just like GL_LINE_STRIP or something similar

[versed light]

i see because when radii is rather large they are visually very inaccurate

spend the last few hours confused why my geometry math was not matching what i was seeing

[wintry quarry]

Yeah it's definitely an approximation with a set number of subdivisions

[versed light]

i feel like SDF would be perfectly accurate with not much more performance hit

[gaunt sandal]

I am having trouble getting my unity editor to recognize my android device when i build.

• Unity installation: 2022.3.47f1
• Android type: Samsung Galaxy Note20 Ultra 5G

So far, I have tried going to the Android environment setup manual entry, but that was really hard for me to understand right now.

[versed light]

other than limits of floats of course

[teal viper]

You basically need the android build support installed and development mode enabled on your device. That should be enough.
Also #📱┃mobile

[gaunt sandal]

development mode?

how'd i manage to miss that lol

[teal viper]

Sorry, "developer mode". This is really not a unity thing:
https://developer.android.com/studio/debug/dev-options

As well toggle debugging over USB(if you plan on connecting via USB).

        {
            if (value)
            {
                Transform parent = transform.parent;
                while (parent != null)
                {
                    ExecuteEvents.Execute(parent.gameObject, eventData, functor);
                    parent = parent.parent;
                }
            }
        }

[static cedar]

You know what they link.

[rocky canyon]

if its beginner coding concepts then sure

[sturdy cairn]

Idk if it is lol

[rocky canyon]

well whats the problem?

[sturdy cairn]

I added a script for player attacking and made it trigger whenever I click. But now when I click, my player goes invisible and is only visible when I do click. I've tried to find the root of this problem for a few hours now and I know for fact, it's the new attack script.

[rocky canyon]

what does the script do?

does the gameobject get disabled? is it the graphics that go invisible? like a renderer or something?

[sturdy cairn]

I'm not sure. All I know is that the entire placeholder sprite that I have goes invisible. I don't think that they stop rendering entirely. Would it be better if I just sent the code for this script?

[rocky canyon]

if the issue didnt begin until after the script was added as i think u said.. then ya the script would be useful !code

}```

[sturdy cairn]

Well its visible when I click, and it was visible before this. Theres no animations as of now. It just spaces an object that I'll put some sprite in later.

[cosmic dagger]

What GameObject are you activating and deactivating?

[slender nymph]

there's nothing in the code you've just shown that would make the sprite on this object turn invisible. show the hierarchy setup and the inspector for this object and the camera

[sturdy cairn]

I'm not fully sure since I'm following a tutorial for it. But I believe it's a box collider

[cosmic dagger]

Make attackArea a [SerializeField] and assign it from the inspector. Turn that GameObject on and off in the editor. Does your apeite appear and disappear?

[sturdy cairn]

I'm not sure what the inspector is.

[slender nymph]

you should start with the essentials pathway on the unity !learn site
also assuming the component you showed is attached to the Player1 object, the sprite is the first child of that object which is the one you are deactivating

[eternal falcon]

:teacher: Unity Learn ↗

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

[cosmic dagger]

You should always learn the fundamentals first, like the windows and how to use the editor . . .

As I thought, you are deactivating the sprite GameObject . . .

[sturdy cairn]

I thought that too but I have no idea why or how to fix that

[tawny grove]

Hello, i know it is generally discourage to have two tiles collide/intersect, but if both of them are non moving tiles, what issues can it actually cause? I am asking because i want to have a removable wall, but i dont want to have to manually edit the tiles of the floor below in script to make it flow right. would it be fine for me to overlap some of the walls tiles in a tilemap ontop the floors, so i could remove the wall all at once while revealing a already made floor below?

[cosmic dagger]

Before continuing the tutorial, you need to understand what each line of code does. If you follow along, you can see that your code grabs the first child of the transform and deactivates it

The transform is the "Player 1" GameObject and the first child is the "Gladiator_Player_1" GameObject . . .

[sturdy cairn]

Oh I get it

attackArea = transform.GetChild(0).gameObject; This line right?

[rocky canyon]

use Debug.Log(attackArea.name); in ur script

you'll see which object u after have assigned in the console

[sturdy cairn]

I have a bit of intermediate java knowledge so I'm not CLUELESS. It's just my first time dipping into unity and it's for a project

It's returning this in the log. So it's assigning attackArea as that first thing then?

[gaunt sandal]

Feel like you need to join a call

This would probably be easier explained that way

[sturdy cairn]

Yeah probably. I think I get the problem now. Just need help with a solution

[pulsar violet]

):

I am using unity 5

[verbal dome]

Why

Haven’t heard that name in like 6 years

Cause my old pc doesn't support unity 6

[edgy tangle]

Or maybe longer…

[pulsar violet]

It doesn't even support 2021,2022,2023

Pretty sure that unity 5 is way too old for C# extension

[pulsar violet]

Or anything

Yea

It is too old

Thats the reason why i am using monodeve

Cause it still has some intellisense

Its giving me an error

[pulsar violet]

I was wondering the same thing

Lmao

[edgy tangle]

You can’t SetActive on an array

[pulsar violet]

What is array

[edgy tangle]

You need to get an element out of the array or use a for loop if you want to do it to them all

[pulsar violet]

Ok

[edgy tangle]

Do you just need a single gameobject?

[pulsar violet]

Ok its kinda complex

[faint agate]

No, I have mutiple walls I would like to activate

https://pastecode.io/s/zodaafpz

heres the script incase but ill look into the forloop method

[edgy tangle]

Yes you need to use a for loop or a foreach loop

Just use foreach

I’m on mobile so forgive me code format police.

But you need to do:

foreach (var target in Targets)
{
target.SetActive(false);
}

[pulsar violet]

My code says

Logic = Gameobject.findgameobjectwithtag("Logicscript").getcomponent<"Logic"> ();

Sorry i am on mobile too atm

if you run into trouble then go through this https://unity.huh.how/ide-configuration

[burnt vapor]

For your information, capitalization is important in C#. You must use proper capitalization or you will not find the method (or conveniently use a method with different casing if it were to exist)

Also, I don't understand how this can be an issue. If your editor is properly configured then it would provide the available methods for you.

So I can only assume it's not configured

[pulsar violet]

I did it

The problem is i am using unity 5

I changed the preference to visual studio code

But Still doesn't work

[burnt vapor]

So if you type Get in the code then it suggests the method?

[pulsar violet]

No

Thats why i used monodevelop

It kinda helps complete the code

But it lacks the basic facilities that visual studio code provides

[burnt vapor]

Monodevelop???

[pulsar violet]

Yessir

[burnt vapor]

Isn't that like ancient and no longer developed?

[pulsar violet]

Yes

[burnt vapor]

Why aren't you sticking to the newer versions?

Visual Studio Code now has C# Devkit

[pulsar violet]

Well i am on a older visual studio code too

1.70 i think

[burnt vapor]

Why?

[pulsar violet]

My pc is 32 bit and win 7

I don't see how a different plugin would not work

[burnt vapor]

Also, Unity 2022 LTS still works on Windows 7

C# devkit

            if (enemy.dead) {
                enemies.RemoveAt(i--);
            }
    }

I was confused why enemies.RemoveAt(i--) doesn't give compile time error. I thought i-- meant subtract i with 1 and return nothing, does it also return the value of i-1? Or am I completely misunderstand it?

[rich adder]

yes

i-- returns i = i-1

Ohh this hurts my soul, is changing a list mid loop of the list fine in c#?

[rich adder]

thats the loop shuld go reversed , yes its normal to do this when reversed

[lean basin]

I thought that too. I thought it's gonna skip one enemy, but it might not be

waiit a minute shouldn't it be enemies.RemoveAt(i); i--? The script above would remove the previous entry on the list wouldn't it?

[rich adder]

yeah no idea what they're going for here.. its removing the the previous enemy

[scarlet shuttle]

How is it reversed? It’s not starting at enemies.Count and doing i— every loop

[rich adder]

No i meant, you can remove items mid loop but only if reversed

[scarlet shuttle]

So this is bad? In this case

[rich adder]

I have no idea what they're going for tbh. They might be confusing what the function does

[scarlet shuttle]

This is just all sorts of bad

[rich adder]

just cause its not compile error, doesn't mean it does what they think it should

[scarlet shuttle]

Does c# loop indexes? Like -1 is the last element
