[drowsy mortar]

Not sure if there's any better place/channel to ask this, but im new at working with Unity, and one of my friends sent a script from a project he made, that uses Smooth Moves (Anim Plugin) AtlasTypes.SmoothMoves, Smooth Moves is deprecated (at least from what I've seen) and I don't own smooth moves, so I was wondering if there was any similar alternative for a smoothmoves atlas in any part of the C# section of the unity animation system (I added using UnityEngine.Animations;) that I could replace it with(I couldn't find any results while searching up some thoughts, also sorry if english is bad)?

[cosmic rain]

What does the AtlasTypes.SmootgMoves do? You need to know that if you want to replace it.
Also, deprecated doesn't necessarily mean that you can't use it.

[drowsy mortar]

From what I could find, it seems SmoothMoves comes with it's own atlas builder, that can create sprite atlases for the user and allow the user to manually edit sprite pivot, my best guess is that it references those types of files.

[buoyant mural]

If your friend send the script why not tell him to send it's plugin too

[buoyant mural]

But I think a better place to ask is #🏃┃animation

[drowsy mortar]

worked with plugin

[ocean osprey]

All of these sprites move at the same time, in the same direction.
But I want to know if there's any other way I could simplify this, instead of having a huge block of this, Could anyone help?

[buoyant mural]

Is this a list?

or all variables

[ocean osprey]

And is there any way I could move them at the same time in C#

[buoyant mural]

Yes

If you make an empty GameObject and then put these objects you want to move the empty GameObject's children or if you want it in code use lists or arrays then foreach

[ocean osprey]

They're all seprate

[buoyant mural]

That's not good use:

[ocean osprey]

I'll try this

[buoyant mural]

public List<GameObject> objects;```

or use

public GameObject[] objects;```

[buoyant mural]

But if you want them to move at the exact frame then make an empty GameObject

it's easier

[ocean osprey]

I've tried this already but I can't figure out how to move them

ok

[buoyant mural]

foreach(GameObject objectToMove in objects)
{
    objectToMove.Move();
}```

[ocean osprey]

I'll give that a go

[buoyant mural]

you could try using this but I highly suggest the empty GameObject method

[ocean osprey]

ok

I'll do that next

[buoyant mural]

The foreach method is very expensive

[ocean osprey]

Oh ok

[buoyant mural]

Just do this and move StuffToMove

[ocean osprey]

Yeah I'll do that

[buoyant mural]

So did it work?

Of course don't move UI with the rest of objects

[ocean osprey]

Wait

no its not your fault

I made a typo

It's working

Thanks

[open lake]

Hey

[rotund burrow]

i'm trying to use NavMesh.CalculatePath, but it returns false. i have a basic flat navmesh

[hexed pecan]

Try moving your start position onto the navmesh with NavMesh.SamplePosition before calculating the path

[ancient rock]

Hey, so currently I have two properties which detect the rotation around the horizontal and rotation around the vertical axis (respectively). How does one go about also making this happen for touch screens?

[wet condor]

in Truck Game
im trying to connect trailer with my truck
so i use configurable joint but i have few issues...

1. my trailer is floating like balloon in starting lol (it get on ground when i move truck)
2. my wheel colider bounce when it touch with other object
3. my trailer just keep moving left and right the limit i have provided

Any Suggestions or Helpful material ? Anyone can suggest

[rotund burrow]

it also returns false. does it do something like a sphere check?

[hexed pecan]

It tries to move the position to the navmesh inside the radius you give it
https://docs.unity3d.com/ScriptReference/AI.NavMesh.SamplePosition.html

[hexed pecan]

@rotund burrow How did you use it? Maybe you did something wrong

[rotund burrow]

NavMeshHit hit;
if (NavMesh.SamplePosition(transform.position, out hit, 100, groundMask))

[hexed pecan]

What is groundMask

Are you using a normal LayerMask?

[rotund burrow]

yes

[hexed pecan]

You need a NavMesh area mask

If you want every area then use NavMesh.AllAreas

Or GetAreaFromName if you have specific areas

[rotund burrow]

okay it works now, thanks

[buoyant mural]

@hexed pecan the code you gave me yesterday isn't really working

            Vector2 forward = new Vector2();
            forward.x = transform.forward.x;
            forward.y = transform.forward.z;
            Vector2 direction = destination.position - transform.position;
            float angle = Vector2.Angle(forward, direction);
            Debug.Log(angle);```

[obsidian eagle]

Hey, I'm new to Unity but more familiar with coding especially C#. So yesterday I started with my 4th project but there is something not right with my scene management. I created my project and added a canvas than in inspector menu I selected my main camera for render camera, render mode to Screen Space - Camera. Than added an Image background. Lastly I tried to add buttons but it seems that i can't click on them.

Also I added Box Collider 2D for the button. I don't think there is any overlays in the scene but again no idea why its giving me a problem. Because I have used UI buttons and OnMouseDown() method buttons and didn't get any problem like this. Any help will be appreciated 🙂

[hexed pecan]

I didnt give you any code, I told you the steps to do it, and you did it wrong.

[buoyant mural]

I meant that

yeah

[buoyant mural]

ok well um what did I do wrong here?

[hexed pecan]

Why dont you use Vector3's like I suggested

[buoyant mural]

I did

today

got same result though

[hexed pecan]

How do you expect this to workcs Vector2 direction = destination.position - transform.position;

Those are Vector3's and you assign it to Vector2

[buoyant mural]

oh yeah

[hexed pecan]

I gave you very clear steps idk how you did it differently

And even suggested using Vec3 because its easier to understand in this context

[buoyant mural]

Ok turns out I tried using Vector3 wrong today my bad, now it's working when I did it right

[hexed pecan]

Read^

[buoyant mural]

It worked

[thin aurora]

What I would do it make this an instanced class, and have it implement an interface (for example IInputHandler) that enforces RotationAroundHorizontal and RotationAroundVertical. You can then make this class MouseInputHandler, and have a different one be TouchInputHandler. You then have a general manager to keep track of input, and depending on what input is used, it will assign one of the classes to a variable IInputHandler inputHandler;. You then get the values from this.

[ancient rock]

I didn't ask design choice advice...

I asked how do I get similar axis from touch input.

[thin aurora]

As in the methods?

[plucky inlet]

the boxcollider is not meant to be used in UI scope. You first gotta make sure you got an EventSystem in your scene and also a graphics raycaster on your UI Canvas

[ancient rock]

As in, what's the equivalent to GetAxis() for touch.

[plucky inlet]

Did you check the touch API from Input?

https://docs.unity3d.com/ScriptReference/Touch.html

Is there an elegant way to target a specific value like position or rotation in a generic way? Imagine a static coroutine to call and modify by just throwing transform.position as value in it but also transform.scale for example?

[hexed pecan]

Can you show a pseudo-C# example of how you would use it?

[plucky inlet]

Like this, so the second param would be the thing I want to modify.But maybe its just overcomplicating things and I should go with an enum. I just want a generic method to get rid of running coroutines for every animated class

this.AnimateScale(Easing.Ease.Spring, transform.position, Vector3.zero, Vector3.one * 5, 2);

[hexed pecan]

Hmm theres no way for it to automatically tell whether you are giving it euler angles, position, or scale

Youre using Scale in the method name but transform.position as argument, im a bit lost here

[plucky inlet]

Nah i just added the position for your reference of pseudo code, my bad. Just imagine its AnimatePosition()

I guess I might just go with an enum or three static functions to call scale, position or rotation and be good with that

[hexed pecan]

Normally you could pass it in as ref if I get what you mean but its not really possible with propeties like transform.position etc

[plucky inlet]

as we are in this scope, could you imagine a good way of adding a coroutine to a monobehaviour like extending every mono with a static animationroutine that can be updated? Or would you just create an inheritance of that mono adding all the functionality?

[hexed pecan]

Hmm can you add IEnumerators as extension methods?

Looks like it might be possible

[plucky inlet]

So right now I am doing this https://hatebin.com/ckbhlsmqcf

Just testing, again, ignore the position / scale naming issue 😉

[hexed pecan]

I was thinking just a IEnumerator extension but with your way, with the intermediary MonoCoroutine you can store a reference to the coroutine so it seems good

So no, I cant think of a better way than that currently

[plucky inlet]

Alright, so I might just extend this to be able to have multiple coroutines as you can animate scale and position in parallel best case. Thanks for your feedback! 🙂

[tame zealot]

Hello, how do you reference this question generator into the text component, im still not getting it, tq

[plucky inlet]

Can you give a bit more detail what you mean?

[tame zealot]

I have a button in the scene, when you click the button a new question will pop, from the text object that I placed

I already have the button working when you click it but its blank

[plucky inlet]

You never call an update on the questiontext cause you never call the int method above

[tame zealot]

yay it works tq! .

[plucky inlet]

Anyone knows why a coroutine might not be started again after being stopped? The reference is correct, cause it stops it, but it does not start it again. Routine is an IENumerator

mono.StopCoroutine(iENumType.routine);
mono.StartCoroutine(iENumType.routine);

[hexed pecan]

Is routineof type IEnumerator?

[plucky inlet]

Yes, it is

[hexed pecan]

I'm not sure how the StopCoroutine(IEnumerator) overload is supposed to work

But I know that StopCoroutine(Coroutine) works

[plucky inlet]

StopCoroutine is working fine on that, but not the start one

But only after I started the routine once, it tries to restart but only stops if possible

I assume the ienumerator kills itself after being done

[hexed pecan]

What if you try cs StopCoroutine(coroutineReference); coroutineReference = StartCoroutine(...);

[plucky inlet]

coroutineReference would be of type Coroutine in your case?

[hexed pecan]

Yea

Store it in the mono or something

[plucky inlet]

I tried that before, but let me try again. I observe that the function you create as an IENum might just be removed when done, so StartCoroutine(Animate(...));, the animate(...) is cleared after finished or stopped, let me test real quick

Hm, the object is still there

[hexed pecan]

Im reading the doc, am I the only one confused by this?

Note: Do not mix the three arguments. If a string is used as the argument in StartCoroutine, use the string in StopCoroutine. Similarly, use the
IEnumerator in both StartCoroutine and StopCoroutine. Finally, use StopCoroutine with the Coroutine used for creation.

[plucky inlet]

I think that is the three options you have, String, IENumerator or a Coroutine itself?

[hexed pecan]

Yeah but the last sentence says to stop it with Coroutine

[plucky inlet]

so string and ienumerator is the common way, nut sure about the Coroutine used for creation thing 😄

yeh, its confusing

I think they just call the IENumerator coroutine here

if you check the samples

oh well, you can stop a Coroutine with that type

[hexed pecan]

I always stopped coroutines with a Coroutine reference so thats the only one I know to work for a fact

[hexed pecan]

So that works in your case?

[plucky inlet]

Stopping always worked, let me refactor to start not the inumerator but set it to a coroutine reference

Argh... 😄 still not working

[hexed pecan]

What is iENumType? What if you store the coroutine in the mono?

Also how are you starting it currently

[plucky inlet]

 public class IENumType
        {
            public IENumType(AnimationType aT, IEnumerator r)
            {
                animationType = aT;
                routine = r;
            }

            public AnimationType animationType;
            public IEnumerator routine;
            public Coroutine coroutine;
        }

MonoCoroutine.IENumType monoCoroutineIENum = new MonoCoroutine.IENumType(animationType, Animation(monoCoroutine, animationType, easeType, startVector, targetVector3, duration));
monoCoroutineIENum.coroutine = mono.StartCoroutine(monoCoroutineIENum.routine);

the animationtype is just to separate position rotatino and scale lerping

Just found this with the right google terms...
You can't reuse the IEnumerator that is returned by a generator method. Such an IEnumerator can only be used once. You have to create a new one each time you want to start a coroutine. Also it's better to use the Coroutine instance that is returned by StartCoroutine to stop the coroutine.

[hexed pecan]

Ah so the problem is with passing around the IEnumerator?

[plucky inlet]

Yep, it just gets used and then gone, fire and forget 😄

well, I guess I just have to pass in the animate() thing everytime, also on restart

[obsidian eagle]

yeah it was the graphics raycaster thanks a lot

[hexed pecan]

Or use the string overload?

[plucky inlet]

Then I could not pass any values in 😉

[hexed pecan]

Is this that one use case where it would make sense?

Oh right damnit

[plucky inlet]

https://hatebin.com/eesjuajlyq if you are interested, this is working now 🙂

[leaden mural]

Hello. I was wondering if somebody could help me with an issue with coroutines. I am trying to make it so whenever a certain coroutine is ran, it sets a bool to true, and then after 1 second, sets it back to false. However this coroutine only runs once, and I need it to run every time a bullet collides with an enemy. I tried finding a solution, and saw somewhere that I have to use a while loop to get it to run multiple times, but when I use a while loop, the bool never switches back to false after a second.

[obsidian eagle]

hey guys I have another question. When the button is clicked how can i get the text thats on the button? The button doesn't have any children component and it's using TMPro.

I'm trying to referance it by using

string nameItself = gameObject.GetComponent<TextMeshProUGUI>().text;

[plush sparrow]

I have 5 dice
Each containing a dice script that generates a random value
How do I collect the dice value from each of those dice

[leaden mural]

My code if anybody is willing to help: https://hatebin.com/vlawucfoer

[lyric barn]

I have a question regarding tilemaps. So I have for example a room I painted, now I want to take that room and paint it somewhere through code, how do I do that?

[hexed pecan]

So you want the coroutine to run again every time you start it in OnTriggerEnter?

Or just one coroutine that loops?

The while loop is for repeating code inside one coroutine

[neat hollow]

[SOLVED] I had a random assebly definition script in project folder that didn't reference any scripts. So made new one and delete the random one at it worked. thanks for the assist

[leaden mural]

Yes, I want it to run every time the bullet collides with the trigger/enemy.

[leaden ice]

The text is almost always in a child object of the button

[hexed pecan]

Your current code should work, just without the while loop

Remove the while and put some logs inside the coroutine to see if it actually runs again or not

Make sure you dont get NRE or other errors in the console while playing too

[leaden mural]

Hmm. Debug.Log says the coroutine is running, but ran a Debug.Log on the boolean and it isn't switching back to true after the coroutine is started again.

[hexed pecan]

Which bool is that?

[leaden mural]

zombieKill. It sets to true once, and then after a second, turns back to false. But it stays false whenever it tries to run the coroutine again.

[hexed pecan]

Hmm. Are you sure that some other script isnt changing zombieKill?
The issue doesnt seem to be in the code you showed

[obsidian eagle]

I created a TMPro text and added button to it. So it's not a child

[leaden mural]

The only other script using it is my GameManager script. And it's just a simple update function. if zombieKill is true, add points.

[leaden ice]

You need to explain your issue then

what's going wrong

[obsidian eagle]

I attached this code to the button itslef

string nameItself = gameObject.GetComponent<TextMeshProUGUI>().text;

and I got this Error message that I don't how to solve

"Object reference not set to an instance of an object"

[leaden ice]

your script is not on the same GameObject as a TextMeshProUGUI component

[obsidian eagle]

In my mind I'm referancing the object by calling gameObject

[leaden ice]

gameObject gives you the GameObject your script is attached to.

[hexed pecan]

And you removed the while loop, right?
Can't really speculate further without seeing more code
Also where exactly are you logging the value of zombieKill?

[obsidian eagle]

It's attached to the same object

[leaden ice]

Show the inspector?

[thin aurora]

What about string nameItself = gameObject.GetComponent<TMP_Text>().text;?

[leaden ice]

can you show the full error messge (with the line number) and the full Select Num script?

[obsidian eagle]

Here is the update function in the GameManager script: https://hatebin.com/obzzhhemov

[leaden ice]

Your error is on this line:
GameControl.clickCount += 1;

you need to pay attention to your error message

it's because you haven't assigned GameControl

[thin aurora]

You didn't assign GameControl if you check your inspector...

[leaden ice]

clearly visible in your screenshot that it is not assigned

[hexed pecan]

Looks ok, are you sure you dont have multiple GameManagers in the scene?

[leaden mural]

Here is the KillsPlayerOnTouch script: https://hatebin.com/jtpehizfwv

Let me check

[obsidian eagle]

GameControl is another script. I tried to update a method that's in GameControl

[leaden ice]

I know what you're trying to do

[hexed pecan]

Type t:gamemanager in the scene's hierarchy search bar

To search by type

[leaden ice]

We've just showed you what your problem is @obsidian eagle and how to fix it. Good luck.

[leaden mural]

Yeah only one, attached to the gamemanager object

[obsidian eagle]

Alright, thanks...

[thin aurora]

But you didn't assign it in the inspector, so there is no reference to call.

[obsidian eagle]

how do I assign a script in the inspector?

[leaden ice]

drag and drop

[obsidian eagle]

no it's not an object it's a sciprt

[leaden ice]

you're wrong

it's a reference to an object that has a script attached to it

you must drop a GameObject which has the script attached to it into that slot

NOT the script itself

[obsidian eagle]

Still getting the same error. I know it's a pretty basic one but I've been trying to solve it for almost 2 hours

[leaden ice]

did you assign the thing?

[obsidian eagle]

yes

[leaden ice]

then you will not be getting the same error

read your error carefully

it is probably slightly different now

Part of the reason you are working on this for so long is you did not read your error carefully. Remember you were looking at the wrong line of code for a while.

[thin aurora]

Screenshot your inspector, please

[obsidian eagle]

Alright I found the problem. I was clicking on the one that I didn't attached the game object to.

Thanks a lot guys

[leaden mural]

Thank you anyway. I'm gonna reach out to both my professor and the creators of this Unity Asset we have to use for our project to see if they can help solve the issue or if I'm just not seeing something

[hexed pecan]

Make one last check to see if anything uses the zombieKill bool (use your IDE's tools)

Ping me if you find the cause, maybe theres something I just cant think of right now 😄

[tame zealot]

Hello, can anyone help me, how to reference this script into a button?

[dim spindle]

by adding it to the button's event list

assuming you want that script to run every time you press a button

[hexed pecan]

Random.Range has an int version btw

[tame zealot]

But how do I make it change the text of the button?

[dim spindle]

by passing a ref to the text

and then .text on that ref

[tame zealot]

is it somthing like this?

answerText_1.GetComponentInChildren<Text>().text = answerChoices.ToString();

[subtle herald]

Well you don't want to pass the entire list. Presumably you'd only want a single value from it.

Nvm, I see what you're doing I think. So you'll just want to concatenate them or something else.

[tame zealot]

Im trying to make a simple math game and cant figure how to get button to change

[vagrant agate]

Does FindObjectOfType start top down in hierarchy ? I'm wondering if its an issue using it only for finding my canvas component. It sits at the very top of the hierarchy. I'm only calling it when spawning a popup prefab to assign it to the canvas transform.

performance wise

[mystic ferry]

the hierarchy is a tree, and FindObjectOfType uses DFS I believe

that said, FindObjectOfType is one of the worst, least performant ways to fill a dependency

[vagrant agate]

gotta love chat gpt explanations. a google search led to looking at different links.

[leaden ice]

FindObjectOfType does no follow any guaranteed hierarchy search order and may change from platform to platform and in different Unity versions

[vagrant agate]

In my game , I only have around 200 GO's at any given time. Do you think it would be a problem finding the canvas using that method ? It is only to spawn dynamic popups for tutorials.

It may not even be that many GO's

[mystic ferry]

if you cache a reference to it, it's not THAT bad. As long as you aren't calling it in Update or something

still, it might be better to have a field in a manager class filled with an Instantiate or something

just keep an eye on the profiler when you build it. If that's causing the issues, refactor it

[vagrant agate]

I cant really cache it in my manager since the tutorials happen even after scene change

[mystic ferry]

do your managers not persist through scenes?

[vagrant agate]

they do but i'm using a utility DDOL class to spawn my popup prefab which finds the canvas in whatever scene its in

[leaden ice]

not really sure I'm following how this precludes a typical singleton setup

[vagrant agate]

when the scene changes..the canvas does also.. So you can't cache the object of my canvas once its found the first time

[leaden ice]

void Awake() {
  instance = this;
}```

that's all you need, no?

[vagrant agate]

Nah, I have my Utility Class DDOL singleton <~~ that has a method that spawns a popup prefab which also has a WindowPopup Script.. It needs to find the canvas no matter what scene it is in so I can parent the popup to the canvas transform

[leaden ice]

right and I just showed you what to put on the canvas in order to find it

you could also just make the canvas DDOL

especially if it's a popup - it should probably have its own canvas

[rain minnow]

If you have a manager that is DDOL just make a variable on it and reference the canvas gameObject . . .

Or does the canvas not persist through scenes?

[vagrant agate]

It doesn't

[vagrant agate]

This would work, I guess I would still need reference to the primary canvas to get my custom scaling values to apply to the popup's canvas though. This is a mobile app, So I have some custom values for screen referencing depending on device.

[rain minnow]

Then as Praetor suggested, make a canvas that persists for pop-ups . . .

[vagrant agate]

Ill try that and see what happens

[rain minnow]

You should have separate canvases for different UI where necessary to avoid redrawing canvases . . .

[vagrant agate]

You make a great point

well I have a few days of refactoring now... lol

[sweet raft]

Is there a way to give a name to an Array Element (that shows up in the Inspector), without going the route of making a struct to hold the Element data and making the first variable of that struct a string? For example, if the Array is an Array of ScriptableObjects, and you just want the Element name to be the name of the created ScriptableObject.

[leaden ice]

Using a custom inspector or property drawer.

[sweet raft]

Gah. I was afraid that might be the only way. 🙄

[soft wave]

I'm trying to implement portals and I'm very confused on how to implement the object cloning
I need to create a copy of the object being teleported that is put at the other portal until teleportation is done, but just instantiating a copy seems too complicated
I'd have to remove all of the scripts but also find a way to keep animation working
Does anyone have a good approach?

[leaden ice]

make a "proxy" object as part of your normal object prefab

with all the stuff set up on it

and show it in the right place/right time when necessary

otherwise hide it

[outer plinth]

When combining meshes with CombineMeshes, are there certain rules that need to be followed to allow the meshes to combine?? I'm almost certain I'm not doing anything wrong but I can get it to work at all

These are the meshes in question

Like can I only combine meshes that contain no space or do the triangles and vertices have to all meet together??

    if (i < numStars)
    {
        tmpStar.style.backgroundImage = new StyleBackground(starsFull);
    }
    else
    {
        tmpStar.style.backgroundImage = new StyleBackground(starsEmpty);
    }
}

which should I be doing?

Im guessing 1 for statement with the int but not sure

[mellow sigil]

for (int i = 0; i < 5; i++)
{
    var tmpStar = starsList[i];
    var bg = i < numStars ? starsFull : starsEmpty;
    tmpStar.style.backgroundImage = new StyleBackground(bg);
}

[outer plinth]

Ah nvm fixed

[thick socket]

could you explain the var bg line for me pls 😄

[mellow sigil]

I'm guessing you mean https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/operators/conditional-operator

[primal solstice]

does any one know how to make my character not float when he goes off the map?

[sterile crown]

add a ridgidbody with physics enabled

you need gravity scale to be larger than 0

[granite nimbus]

is there a better way in C# to return multiple values from a method than just packing them into a struct / using ref or out?

something more convenient, maybe like
public (int, bool) Method()
idk

[mellow sigil]

https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/value-tuples

[thick socket]

pretty much your choice is tuple or struct/class

[granite nimbus]

oh right, this is really cool

thanks

[cobalt flint]

Is GetComponent considered FindObjectOfType during runtime?

[granite nimbus]

I mean a struct/class is just an overkill for this purpose, tuples seem more convenient and natural

[thick socket]

makes sense

[granite nimbus]

it may be worth doing a struct if you return many many values, but for two or three, I think it's tuples

but if you return many values, maybe you're doing something wrong with your method😀

[rain minnow]

It's basically the same thing as a tuple, the main difference is a tuple is temporary if only used for the method or seldom. If you need it in multiple places then a struct is more preferable . . .

[rain minnow]

Two or three is fine for a struct. A struct shouldn't be more than a handful of fields anyway . . .

[granite nimbus]

yeah the sole purpose for me is to return a (JobStruct, JobHandle) pair from a method, that's it

[rain minnow]

Nope, not the same thing . . .

[plush sparrow]

How can I lock the value of a variable after changing it once?

So that it can't be changed again

[leaden ice]

Use a bool variable to track if it's been changed already

[plush sparrow]

There are many variables
Which I have to control individually

Bool approach is not appropriate

[leaden ice]

use a bool for each one

or

make a type that contains your value and a bool and change your variables to this type

or asasign these values in a constructor and make them readonly

[cobalt flint]

I didn't think so. I'm trying to understand why I'm seeing "FindObjectOfType" in my profiler during runtime, when nothing ever calls that except in start/initialize. LONG after the game has starting basically its showing up

[plush sparrow]

Cannot make them readonly
As I have to change them for a certain amount of times

[cosmic rain]

Kinda feels like you're trying to solve a problem backwards.

[leaden ice]

then go with one of the other mentioned approaches

or better yet - explain what you're actually trying to do so we can recommend a sensible solution

[plush sparrow]

Oh

Like I have some combination of dice

5 dice

I roll them until I find a specific combination
I am updating the total after every roll

But once I lock the combination
I don't want the total to change

[leaden ice]

bool isLocked

[plush sparrow]

5 dice with 13 things that can be locked or not locked

Is bool the correct way?

[leaden ice]

struct thing {
  int value;
  bool isLocked;
}```

[plush sparrow]

Oh

Thanks

[leaden ice]

as mentioned before

[stuck robin]

hmm so this probably sounds dumb but I made my own input field class, as I found the input field also acted liked a scroll rect and I needed it parented to a scroll rect, so it was double scrolling. But now I'm having issues with implementing the selection caret -_-

one problem for another lol

like tracking the user pos is easy enough, but I can't figure out how to create the actual caret. do I add a | pipe to the end of the .text component? use a rectangle graphic bar thing? or something else

[near wagon]

?

[stuck robin]

I guess I could skip the selection caret, but that presents a design problem in regards to text input as this is for an in-game code editor

[thick socket]

ugui or ui toolkit?

[stuck robin]

i was using the textmeshprougui class for the text components, so whatever that is

[ebon pendant]

does anyone know roughly what this error means?

[stuck robin]

I think with the legacy text components you can call methods on the vertices of the text mesh and get info that way to render the caret but Im not sure what the equiv methods are for TMP

[near wagon]

help please?

[leaden ice]

It means you tried to change the parent of a Transform which exists in a prefab

[ebon pendant]

oh lol

thanks

[polar marten]

you draw a graphic between the letters and blink it

[near wagon]

anyone?

[placid ridge]

I'm having issues scaling my collider to 0.5 scale, and i've been having trouble figuring out the colliders, i set the cell size to 0.5 any ideas?

[swift falcon]

if someone can help me why am I unable to transform that string into a date?

[mellow sigil]

not without seeing the code

[swift falcon]

I just solved it by doing this ... writing the numbers in the shape of "yyyy-mm-dd" instead of "dd/mm/yyyy"

I thought try parse would parse the 2nd format

[leaden ice]

it will use whatever date format you provide, or the default if you don't provide one

[swift falcon]

I did provide one... it always parsed it as 1/1/0001

i can show you the debugs and code but it is not working

[leaden ice]

that''s your input string, not a date format

[swift falcon]

I dont know what you mean but my string was "27/3/2023" (without the "") as for the parsed value was "1/1/0001" as you can see in the picture above

[leaden ice]

That's what TryParse will output when it cannot parse the input

you need to make sure you are checking the return value of TryParse

[swift falcon]

ok but the thing is I thought it parses the format dd/mm/yyyy not just yyyy-mm-dd

[leaden ice]

if (DateTime.TryParse(...)) {

}
else {
  Debug.Log("Could not parse input string");
}```

[leaden ice]

only if you provide such a format string

[swift falcon]

[ruby trellis]

Hello! I'm making a space game and I need a UI to tell you your velocity relative to the planet and I need to do it per axis so the player knows in what direction the planet is moving in relative towards the player. The problem is the planet and the player don't have a Rigidbody so I need to calculate their speed themselves. This is what I have so far it only calculates the total speed and I cant figure out how to do it per axis (Relative to the player of course).

float distance = Vector3.Distance(currentPosition, targetPosition);
float lastDistance = Vector3.Distance(lastPosition, targetPosition);

float velocity = (lastDistance - distance) / Time.deltaTime * 10;
lastPosition = currentPosition;  

The video is to show what this should look like in gam (Sorry for the Programmer art and the cool spinny move at the end).

[west sparrow]

I'd probably tackle it another way

Public Vector3 LastDist;

private void Update() {

  // How far are we from each other?
  Vector3 dist = that.Transform.Position - this.Transform.Postion;

  // Do we have a distance stored? If not, we need to do this or it will give us a weird number on the first frame
  if(LastDist == Vector.zero) 
    LastDist = dist;

  // Now, what is the distance we've moved since the last frame?
  Vector3 diff = dist - LastDist;

  // Now multiply it by how long it has been in seconds to get the meters per second
  Vector3 speed = diff / Time.deltaTime; // speed is the value you care about here

  // Now that we have the speed, we can store our new distance for the next check to verify against
  LastDist = dist;
}

Something simple like that should get the meters per second, in the X, Y, Z of a Vector3.

[ruby trellis]

Oh interesting, thank you let me just try that out

ah thanks for the edits

[west sparrow]

No problem, it's from my phone, so hopefully close enough to help

[plush sparrow]

I have 5 objects containing the same script

I want to call a method in that script from another script attached to another object

How do I do that other than referencing all the gameobjects individually?

[vagrant blade]

Create a [SerializeField] TheObjecType MyObject; and drag it in.

That's assuming the other object and the one you want to call it on exist in the editor.

If not, then you need a way to identify it. But that depends on when you want to call something on it (such as when you collide with it for example)

[plush sparrow]

How will the serializefield help?

I have multiple gameobjects containing the script

[vagrant blade]

You can drag the one object you want to call on it.

[plush sparrow]

And I want to refer a method in that script that should affect all the objects

Ah I don't want one object
I want all the objects to reflect the changes

[tame zealot]

Can anyone help me, if I press enter on an empty input field it keeps giving an error

[vagrant blade]

If the function has to run on all, you could use a static function. If that doesn't suit your needs and you don't want to reference all the objects in a list and iterate through them, you could consider invoking a function from the other object which all the same ones listen for and handle the results in their own way.

[vagrant blade]

Check if the input field isn't empty before attempting to parse the answer?

[simple egret]

Or use int.TryParse() which returns a bool value indicating whether the conversion was successful or not

You get the parsed number (if successful) in an out parameter

void Moving()
{
  if (isGrounded)
        {
            movement *= speed;
        }
        else if (isGrounded == false)
        {
            movement *= 0;
        }
    }
}
    //------------JUMP------------------------
    private void CheckGrounded()
    {
        isGrounded = Physics.CheckBox(transform.position, boxCastSize / 2f, Quaternion.identity, groundLayer);
    }
    private void Jumping()
    {
        if (isGrounded && p_input.jumpInput)
        {
            rb.AddForce(Vector3.up * jumpForce, ForceMode.Impulse);
            isGrounded = false;
        }

    }```

Why when my isGrounded = false, my speed didn't switch to 0?

[west sparrow]

Awesome!

[west sparrow]

Is Moving() even being executed?

[wide fiber]

sorry this is the full code.

 movement = p_input.xAxis * transform.right + p_input.zAxis * transform.forward;
        movement *= speed;
        movement += new Vector3(0, rb.velocity.y, 0);
        if (rb.velocity.y < 0)
        {
            movement += Vector3.up * Physics.gravity.y * (fallMultiplier - 1) * Time.deltaTime;
        }
        rb.velocity = movement;

        if (isGrounded)
        {
            movement *= speed;
        }
        else if (isGrounded == false)
        {
            movement *= 0;
        }```

Basically just disable the controls when jumping so my player wont feel floaty 😄

[leaden ice]

Once you do this it doesn't matter what movement used to be:
movement = p_input.xAxis * transform.right + p_input.zAxis * transform.forward;

[west sparrow]

Well, first up, this doesnt show me when it is executed but the problem I'd assume is because you are setting rb.velocity = movement; but then changing it to 0 after, and next loop it replaces the 0 with the stuff above before assigning.

So my best guess is move the rb.velocity... line below the assignment.

Yeah

What they said 😄

[vagrant agate]

So how do I get an exact position of a nested canvas UI element so that when I set its parent to null, I can set its position back to where it was?

[wide fiber]

oh ok. thanks so much for the clue @leaden ice @west sparrow !!

[simple egret]

transform.position - not relative to a parent, not relative to your anchoring settings.
I think you can do transform.SetParent(null, true) to keep the position after unparenting

[vagrant agate]

Yea I must have something else going on bc that isn't working for me. Would the same be the case If I the set the parent to a different GO ? My first thought was anchoring but dunno how to mitigate that.

[somber steeple]

    {

        StopCoroutine(ShakeCoroutine(0));

        // Move the spike downwards
        Vector2 dropPosition = transform.position;
        dropPosition.y -= dropSpeed * Time.deltaTime;
        transform.position = dropPosition; I
    } ```  I am dropping a spike when a player is near it. It does have a Rigidbody2D attached it and a collision detection. It's supposed to stop the moment it touches the ground, but sometimes it goes a bit further into the ground before stopping depending on whether the collision happens in between frames. I do have continuous and interpolate enables

[leaden ice]

what's this about?
dropPosition.y -= dropSpeed * Time.deltaTime;

[vagrant agate]

nested object inside canvas > change parent to canvas transform using set parent. that is what im trying to do but it shifts to the left side of the screen

[leaden ice]

Also what's this for?
StopCoroutine(ShakeCoroutine(0)); < this almost certainly is not correct

[somber steeple]

it's supposed to move the spike downward.

[leaden ice]

but why would you do that here?

Where is this running from? Update?

It should be in FixedUpdate if you're trying to do physics

in fact you should just give it a Rigidbody and a velocity and let the physics engine move it

[somber steeple]

    {
        if (!willFall)
        {
            return;
        }

        if (CheckDistanceX() < noticeDistanceX && CheckDistanceY() < noticeDistanceY)
        {
            if (!isTriggered)
            {
                int numShakes = activeOnFirstRay ? 1 : 2;
                StartCoroutine(nameof(ShakeCoroutine), numShakes);
            }
        }

        SeePlayer();
        // Check if the spike is triggered and hasn't already dropped

#archived-code-general message

[rigid island]

Anyone here good with Hex based grids could help me ?
I've been stuck here for a few weeks no Idea how to move forward with this...
Currently have a neighbor detector with my tile, and it works fine, I'm trying to expand it to include my attack range but all my experiments it turns into a weird shapes..
the math is kicking my ass rn
My Current result from my script is the first two images which is fine(red tiles are the current script)

Current script, not much going on ```cs
void Start()
{
Vector3Int[] neighbors = startPos.neighbors();

    foreach (Vector3Int neighbor in neighbors)
    {
        tilemap.SetTile(neighbor, highlightTile);
    }
}```

I'm using unity's tilemap so all the solutions on RedBlogGames are not translating correct

I hand drew it in tilemap but this is something I'm trying to do with current scripts

does this belong in #archived-code-advanced ? I'm so confused

[ebon pendant]

What could these be from?

They don't point to any specific script being the problem

[leaden ice]

just do a DFS to a depth of whatever your attack range is

it's true though that Unity's cell coordinates are weird

but it seems like your neighbors() function works

so you should be ok

[leaden ice]

could be almost anything that uses the job system

if you're not using the job system it's likely an internal unity thing

[ebon pendant]

I am not doing anything with the job system so it must be unity being unity

thanks, just wanted to make sure it wasn't me

[rigid island]

that's the strange part, it does work but once i start expanding it with other algorithms the shape become weird and wonky, for example it gives me weird ellipsoid shapes or squared. I can show you what other scripts I tried and the result

[leaden ice]

can you show the neighbors code

[rigid island]

Yes,
https://hatebin.com/lrkqivwhvc

[leaden ice]

This might be helpful too:
https://docs.unity3d.com/Manual/Tilemap-Hexagonal.html
The coordinate diagram

[rigid island]

trust me I read through it multiple times and also tried some conversion formulas from RedBlogGames but it goes beyond my tiny monkey brain

[leaden ice]

This looks wrong I think
public static Vector3Int southeast(this Vector3Int vector) { return vector.y % 2 == 0 ? vector + Vector3Int.down : vector + Vector3Int.down + Vector3Int.right; }

wait sorry

misread it

thought that was southwest

[rigid island]

it's ok, was about to say lol It does work fine esp when I use it with A* pathing but have no clue on how to expand outward in a circle

[leaden ice]

ok I think your neighbors code looks good (though it might be very gc heavy with all the new arrays

so it's just a matter of doing a limited-depth search then, right?

[rigid island]

basically this if you are able to see it here
https://www.redblobgames.com/grids/hexagons/#range

is Activity a custom class ? does it have System.Serializable

[leaden ice]

I'd just do a breadth first search or something

something like this:
https://hatebin.com/wjqkcypvno @rigid island

[hexed pecan]

@rigid island Lots of learning material on hex maps here btw
https://catlikecoding.com/unity/tutorials/hex-map/
Not sure if there's anything pathfinding-related but thought you'd like it
NVM theres a pathfinding section too 🙂

[leaden ice]

I definitely forgot to add results to the results list in that sample code, and return the list

but should be simple enough to add

Once you've got a neighbors() function that works, it just comes down to standard graph-based algorithms

[rigid island]

will check this out right now. thanks !

[rigid island]

unfortunately pathing isn't an Issue since i got that already going with a*
I'm trying to do a range attack display per character

Think something like X-Com and stuff

but hex, which is making this super annoying (unity tile system grid is weird)

Wait............

I think it's working

dam @leaden ice I think you literally solved this in like 5 minutes

[mystic ferry]

having a strange issue where one of my events seems to be firing twice per button press. I unsubscribe the listener before subscribing it just to make sure the event isn't somehow subscribing twice, and it isn't

I guess the event is firing twice per frame?

[rigid island]

Wow this works ! I can't believe the solution was this simple, no conversion or anything...omg
https://hatebin.com/speifugpjt @leaden ice

[mystic ferry]

but I don't know why. All of my other events work fine

[rigid island]

❤️ much love @leaden ice You smart

[leaden ice]

just basic graph algorithms 😉 you can thank my Algorithms and Data Structures teacher in college from like 10+ years ago

[rotund burrow]

how should i approach making an ai unit with custom movement jump on a navmesh? say jump is just adding some velocity to rigidbody

[rigid island]

glad the knowledge was put to good use, haha dam I should've went to useful college 😦

[hexed pecan]

Are you familiar with GOAP? Goal oriented action planning for AI
I'm making a prototype and was wondering what is the right pathfinding algorithm to look at. It currently uses a simple A* but I'm not sure if thats the right tool for this kinda job?

[leaden ice]

I've only heard the phrase, don't know much about it. Isn't NavMeshAgent an example of this?

[hexed pecan]

It's not really spatial pathfinding like usual

But nodes that consist of actions and conditions

[leaden ice]

Isn't it more like how a mouse does pathfinding

without global knowledge of the space

[hexed pecan]

Theres a world state that I feed parameters into and that is all the agent knows

[leaden ice]

So machine learning?

[hexed pecan]

It wants to satisfy a certain goal/condition, like for example HEALTH >= 100
Then it searches through the graph to find actions that will lead into satisfying that goal by checking the resulting world state
I'm thinking it would find an action that satisfies the goal, and find the "shortest path" to it, but I wont use only distance to calculate the costs but also the cost of the actions and how well they satisfy the desired world state

[thick socket]

if I do rnd.Next(10)

will I get number 0,1,2,3....9,10?

or if one of those missing

[hexed pecan]

No, I don't step into that realm yet 😅 GOAP has been used in video games (F.E.A.R. series, Halo, Half life I think)

Just for NPC behaviours

I'm still kind of wrapping my head around the whole idea

[leaden ice]

Not familiar with it

[hexed pecan]

Alright, was worth a shot heh.

Damn I wish the AI channel was more active and not all the way down there

[thick socket]

I feel it should be up here by coding lol

[hexed pecan]

Yeah 🤔 Most questions seem to be about using the NavMesh but thats probably because its not in the code category

[hexed pecan]

Do you mean System.Random.Next?
https://learn.microsoft.com/en-us/dotnet/api/system.random.next?view=net-8.0

[thick socket]

yeah, I think it includes the min and not the max from what Im seeing

so Next(10) is 0-9

[hexed pecan]

Yeah apparently the doc says it is exclusive upper bound

So 0-9

Just like unity's Random.Range int version

[thick socket]

any reason to use one over the other?

[hexed pecan]

The main difference is that UnityEngine.Random is a static class, but with System.Random you use instances of the class

If thats what you were asking

[thick socket]

gotcha...why would I use one over the other

[hexed pecan]

If you have multiple objects and want them to use their own seeds without messing with each other, you would go with System.Random because you can make instances of it

[thick socket]

gotcha thx

[tame zealot]

Is there a way I can stop object movement after lets say > 2 seconds ?

4- Jump corner correction. If you bonk your head on a corner, the game tries to wiggle you to the side around it.

[thick socket]

the best way...or a way?

[potent sleet]

first you have to say , how are you moving the object?

[potent sleet]

probably clever raycasting

[thick socket]

I was gunna say collider checks, but Null is probably right

[tame zealot]

Ship.transform.position += transform.right * speed * Time.deltaTime;

simple ones

[potent sleet]

in update?
just make a bool

or set speed to 0

[thick socket]

can start a coroutine that waits 2s

then sets the bool

[hexed pecan]

In 3D I would probably use this:
https://docs.unity3d.com/ScriptReference/Physics.ComputePenetration.html
But idk if theres a 2D equivalent 🤔
Actually it could be this
https://docs.unity3d.com/ScriptReference/Physics2D.Distance.html

[sharp blaze]

Is it possible using a corountine to slowly spawn a prefab and its objects and also add like a progress bar to it or something?

[hoary sparrow]

yes, you can increment a value inside a coroutine each time an object is spawned, which in turn can determine the progress of a progress bar

[sharp blaze]

So If I have one prefab with many meshes/objects inside of it how would I do it

?

Get all the children of the prefab

And then spawn the all one by one?

In the corountine?

[hoary sparrow]

that could be one way to do so

[sharp blaze]

Do you maybe have a better way in mind?

Im open to all ways xD

[strange epoch]

This sounds like it could be it, I'll try it. Thanks!

[hoary sparrow]

depends on what kind of thing you want to do
is it something like, a structure being built in front of the player, and the progress bar is the amount of it built so far?

[sharp blaze]

Nono its more of like a smaller map prefab loading for the player

I know I could use additive scenes but

Im also doing networking so it kinda messes up stuff a little bit

So doing it with prefabs would be an okay solution

[hexed pecan]

I havent used that 2D method, lemme know if it works for this

[hoary sparrow]

then ye, prob having some kind of empty parent prefab, and then spawn the sub-prefabs of it one-by-one via coroutine could be a fine solution

[sharp blaze]

Alright, thank you a lot!

[strange epoch]

I'm using tilemap colliders btw, if that changes anything

[hexed pecan]

Probably shouldnt matter, but I cant say for sure

At least the doc doesnt mention anything about it. It just needs two Collider2D's - which TilemapCollider2D is as far as I know

[green lily]

Hey, is there any way to create some sort of global public static gameObject that holds static values like say, int health and int currency that can interact with gameobjects in the scene but can be called without having to directly reference said GameObject instance? I want to store these values in some sort of global "GameState" manager that uses properties to automatically call what happens when the player takes damage (like updating the UI, playing sound effects, etc) but I don't want to fill my code with a bunch of boilerplate that locates said instance or have to manually drag around and place a GameState instance into every single component that needs it.

[somber nacelle]

it sounds like you want a singleton. but it also sounds like you want that singleton to do too much

[green lily]

well i just want it to call functions on other objects when the properties it holds are changed

[somber nacelle]

you should look into events and/or the observer pattern

[green lily]

alr i will

[mystic ferry]

if I have two canvas elements for UI and I want to flip between the two (like between a main menu and an options menu for example), what is the difference between enabling and disabling the parent GameObjects of those canvases, and just enabling/disabling the canvas components themselves?

functionally they seem equivalent, does it have any other effects I'm not seeing?

[marble halo]

another solution could maybe be to use a capsule collider?

trying to remember if unity 2d supports capsule colliders

it does

[mystic ferry]

another question I have is if there's a way to stop unity from overwriting builds? if I want to make a second build so I can refer to the previous build later, is there a way to do that?

[somber nacelle]

just build to a different folder, it's literally that simple (or move prev build to a different folder before building)

just note that it's faster to build upon a previous build than doing a full clean build

[pine bronze]

hey guys, i want to make my character controller jump but when i press space to jump, it teleports me to the jumpForce and then fall down because of gravity. did i do anything wrong?
jump method

    public void Jump(InputAction.CallbackContext context)
    {
        if (canJump)
        {
            Debug.Log($"{movement.x},{movement.y},{movement.z}");
            if (controller.isGrounded)
            {
                movement.y = jumpForce;
                controller.Move(movement);
            }
        }
    }

where i apply gravity

    public void ApplyGravitation()
    {
        if (useGravity)
        {
            if (!controller.isGrounded)
            {
                movement.y -= gravity;
            }
            controller.Move(movement * Time.deltaTime);
        }
    }

[strange epoch]

I think you are setting the position directly rather than the speed.

[pine bronze]

so how would i set the speed?

should i set the y velocity of the controller?

[strange epoch]

The easiest way is to use a rigidbody, and changing the rigidbody's speed

[pine bronze]

but im using a CharacterController

[strange epoch]

I'm not used to using the character controller, so I'm not really sure. Sorry

[strange epoch]

OK, I think this might work but I don't really understand how to use that method, I only need to change the player's x position when hitting the ceiling corner. I can detect when the player should be moved, but not by how much it should be moved

[hexed pecan]

If phys2d.distance gives you a negative value when the colliders overlap, maybe you can use that distance to separate them? After making it positive ofc

But again im not sure how that particular method works, just saw it mentioned in a thread. Might test it tomorrow

[marble halo]

Ok so for some reason when im on a slope too steep to step and im pushing the move keys the character wont slide down

[ashen yoke]

anyone has a hack to open arbitrary cs file in IDE from editor?

nvm they are all MonoScript

[granite nimbus]

when I do foreach for NativeHashMap / Dictionary, in which order does the loop go through? Is it defined even?

[ashen yoke]

should be in sources

IEnumerator in the collection file

my guess its lower to higher

[granite nimbus]

lower to higher what? key? what if key is int3/Vector3Int?

[ashen yoke]

hash

hash is an int

Vector3 hashes to an int with spookyhash

youre doing spatial hashing?

[granite nimbus]

nah, I'm just playing around with HashMap

all I needed to know is it's a defined consistent behaviour

[ashen yoke]

you wont get that, v3 (3812,898,1) can be some -83671289291 int

+1 to it and you get 7772812391

getting data out of spatial hashmap means you have to lookup every time using same key

[granite nimbus]

then I need to store index in my value

[tepid river]

im pretty sure that you should never rely on hash anything being consistent for iterations.
iirc java (or python) even has a built in randomizer to stop people from doing that, because it only works 99/100 times

[ashen yoke]

haha

[granite nimbus]

yeah, I will just store an index in struct that is value. this way I'll get consistent iterations

[ashen yoke]

that means sorting every time you want to iterate?

or just having the position available

[granite nimbus]

no, just looking up for correct index (writing and starting to realise it's just slow)

[ashen yoke]

yeah this smells like xyproblem

[tepid river]

just keep a separate array of the values for iteration

hashmaps are for lookup, not having an order 🤷‍♂️

[tame zealot]

Could someone help me with this, the top if statement is fine but the bottom one starts as soon as I press play how do I make this work?

[granite nimbus]

what do you mean by saying "if statement starts"

[tepid river]

if (!someFlagThatWasNotSetYet)
return;
?

[ashen yoke]

first condition not satisfied, it jumps to second, thats all that happens

[tame zealot]

when I put the answer, the if statement works fine but the else if statement just starts without even me putting in the answer.

[ashen yoke]

second if() is not necessary, else is enough

yes because its in Update()

its called every frame

[granite nimbus]

this means answer != GetCorrectAnswer() 🤷‍♀️

[tepid river]

the logic does exactly what its build to do.
on every frame, do something with the answers.
if correct do this
if not correct do that

if you want it to wait until you do something elsewhere, you need to build your logic to reflect that, f.e. with a boolean flag

[granite nimbus]

we don't know what GetCorrectAnswer() is, but presumably it returns a bool. And you call it every frame. I assume that when you haven't put in the answer (user input?), this method will return false, therefore your second condition is automatically met

[tame zealot]

yes it's just a simple math game, I put the correct answer Sprite moves forward. Wrong answer, sprite moves backward.

[tepid river]

then have your logic wait until there is an answer

[buoyant crane]

wrap all of the logic so that it only runs when answer isn’t "no answer" or whatever the default answer is

[granite nimbus]

can also more conveniently define answer as nullable and check if answer != null

[ashen yoke]

best to hook up a button to check

[wooden horizon]

hey can anyone help me with name spaces and scriptable objects? im using version 2021.2.91f and ive followed many tutorials but none of the have worked. This keeps appearing and i cant create any scriptable objects via the the project content browser. I just cant get custom name spaces to work for some reason

[tidal shadow]

i have these cables that i gave an electrical effect (runtime executed) and they are bent as you can see
i got a nice curve on geogebra using 0.01x^2
how would i apply that simple formula to get new checkpoints along each cable?
code i already have (not done with above idea in mind)

    public void Initiate(GameObject effect, Vector3 pos1, Vector3 pos2, float positionsBetween, float positionOffset)
    {
        this.effect = effect;
        this.pos1 = pos1;
        this.pos2 = pos2;
        this.positionsBetween = positionsBetween;
        this.positionOffset = positionOffset;

        direction = pos2 - pos1;

        CreateEffects();
    }

    void CreateEffects()
    {
        Vector3 length = direction / positionsBetween;
        GameObject? latestEffect = null;

        for (int i = 0; i < positionsBetween+2; i++)
        {
            positions.Add(pos1 + length * i);
            latestEffect = Instantiate(effect);
            effects.Add(latestEffect);
        }

        effects.RemoveAt(effects.Count - 1);
        Destroy(latestEffect);
    }

    public void UpdateEffect()
    {
        List<Vector3> randomOffsets = new List<Vector3>();

        randomOffsets.Add(pos1);
        for (int i = 1; i < positions.Count - 1; i++)
        {
            randomOffsets.Add(positions[i] + new Vector3(Random.Range(positionOffset, positionOffset), Random.Range(-positionOffset, positionOffset), Random.Range(-positionOffset, positionOffset)));
        }
        randomOffsets.Add(pos2);

        for (int i = 0; i < randomOffsets.Count - 1; i++)
        {
            Vector3 halfWay = (randomOffsets[i + 1] - randomOffsets[i]) / 2;
            effects[i].transform.position = randomOffsets[i] + halfWay;
            effects[i].transform.LookAt(randomOffsets[i + 1]);
            effects[i].transform.localScale = new Vector3(0.05f, 0.05f, (randomOffsets[i] - randomOffsets[i + 1]).magnitude);
        }
    }

[mystic ferry]

if I have two canvas elements for UI and I want to flip between the two (like between a main menu and an options menu for example), what is the difference between enabling and disabling the parent GameObjects of those canvases, and just enabling/disabling the canvas components themselves?

functionally they seem equivalent, outside of obviously the different methods you use to interact with them

[tidal shadow]

enabling/disabling parent gameobject disables eveything inside it and its children (including attached scripts)
disabling components only disables that, allowing attached scripts to continue running

[mystic ferry]

makes sense, thanks

[restive flame]

i have this nre but it doesnt show anything when double clikcing it, can someone help

[dusk apex]

Is that the only error?

[swift falcon]

I get value of variable isGrounded every frame, which i refer to in another method that gets called elsewhere.

    void Update()
    {
        isGrounded = controller.isGrounded;
    }
    private void applyGravity()
    {
        if (isGrounded && playerVelocity.y < 0)
        {
            playerVelocity.y = 0f;
        }
        playerVelocity.y += gravityConstant * Time.deltaTime;
    }

But is it necessary for me to have that line in Update()?
Could I instead do

    void Update()
    {

    }
    private void applyGravity()
    {
        if (controller.isGrounded && playerVelocity.y < 0) // <---- here
        {
            playerVelocity.y = 0f;
        }
        playerVelocity.y += gravityConstant * Time.deltaTime;
    }```
Is that mechanically equivalent?

[somber nacelle]

it really depends on when you are calling CharacterController.Move since that is when the CC's isGrounded property is updated

[swift falcon]

oh really? So let's say I'm sitting on a block, and I call CharController.Move(). It will recongizes that I'm grounded. But then let's say the block disappears from me, so I start falling, but I don't call CharController.move(). Will it still think I"m grounded?

[somber nacelle]

yes

[swift falcon]

hm

is it recommended to even use CharacterController?

why not just implement movement myself in my own script

[somber nacelle]

you can, there's nothing wrong with that. you just need to understand how it works and how its isGrounded property works if you aren't ground checking manually

[fluid lily]

I am getting the fallowing error.
The type or namespace name 'Fog' could not be found (are you missing a using directive or an assembly reference?)

Any idea what assembly to add to mine to use this?

[somber nacelle]

also you wouldn't start falling if the ground disappeared from below a charactercontroller because it doesn't have gravity automatically. you are very clearly applying the gravity yourself when you call Move 😉

[swift falcon]

right lol

[fluid lily]

Context.

source = GetComponent<Volume>();
source.sharedProfile.TryGet<Fog>(out var fog);

[quartz folio]

what kind of fog are you expecting this to be?

[fluid lily]

I am using URP with a global volume. I am trying to access the fog settings off of the Volume script.

[swift falcon]

Why does this guy make a Vector3 when the input is a vector2?

Does CharacterController.move() just require that?

[fluid lily]

this is my first attempt so not sure how to go about it.

[fluid lily]

I got the Volume assembly done and can grab the volume component, but just need this fog.

[quartz folio]

I don't know what this fog is? Does URP have a fog volume?

[fluid lily]

yes

[quartz folio]

Well, unless I'm mistaken it's not a default effect

Either way, your IDE should be able to autocomplete or at least suggest the namespace that you are probably missing

[fluid lily]

It is not,,, Though I have an assembly definition that the script is in that I am assuming I am missing(and why my IDE isn't seeing it).

[quartz folio]

The input is a 2D vector, WS/AD or left/right, and the movement is in 3D space, XYZ

[quartz folio]

Which script, the fog script?

[fluid lily]

Yeah it isn't auto getting the Fog namespace. My FogController script is under MyCustomNamespace which is encapsulated by an assembly definition in unity. So for example I had to add an assembly for it to see the Volume type under.

[quartz folio]

Can you search for Fog in your project and find out where it is? Because my URP does not have a Fog volume effect, so there's no way to help you

[swift falcon]

This seems like inconsistent code

public class InputManager : MonoBehaviour
{
    private PlayerInput playerInput;
    private PlayerMotor playerMotor;

    void Awake()
    {
        playerInput = new PlayerInput();
        playerMotor = GetComponent<PlayerMotor>();
        playerInput.OnFoot.Jump.performed += context => playerMotor.Jump();
    }

    void FixedUpdate()
    {
        Vector2 input = playerInput.OnFoot.Movement.ReadValue<Vector2>();
        playerMotor.processMovement(input);
    }
    private void OnEnable()
    {
        playerInput.OnFoot.Enable();
    }
    private void OnDisable()
    {
        playerInput.OnFoot.Disable();
    }
}

So he uses the event delegate system for OnFoot.jump, but he reads the value directly for OnFoot.movement...

couldn't he instead read OnFoot.Jump directly?

like this ```cs
void Awake()
{
playerInput = new PlayerInput();
playerMotor = GetComponent<PlayerMotor>();
}

void FixedUpdate()
{
    Vector2 input = playerInput.OnFoot.Movement.ReadValue<Vector2>();
    bool jump = playerInput.OnFoot.Jump.triggered;
    playerMotor.processMovement(input);
    if (jump)
    {
        playerMotor.Jump();
    }
}```

[quartz folio]

If you're following a tutorial from Brackeys then that's your problem. Find something from someone else.

[swift falcon]

https://www.youtube.com/watch?v=rJqP5EesxLk

it's this guy

[quartz folio]

It does seem like bad code, but as long as you're learning how to write code in Unity then it's doing its job 🤷 it's hard to find youtubers who are going for quality over quantity. Or at least, they have a lot of other work like editing and an inability to backtrack that makes quality difficult.

[swift falcon]

Do you know any resources where high code quality and professional software engineering standards are prioritized?

[fluid lily]

Yeah I gotta track down where I set it up and how one sec.

[fluid lily]

I know I did something through a tutorial for making it work with URP, but I am setting the fog through the Rendering/Lighting/Enviromental/Fog. Not gonna lie it might be powerful but the URP is super annoying to work with. Needed a few more rounds of UX design...

[west sparrow]

Yeah, it's a bit of a make work project.

I don't recommend using URP unless you have a usecase for it

[fluid lily]

I would study the .net side of things. Stuff like api/microsoft.core will be the best coding practices.

Unity can be a bubble of weird practices. And studying other C# industries will be the biggest eye opener.

[fluid lily]

Yeah well a bit late for that XD.

[quartz folio]

So are you trying to set the fog in the environment settings, or do you have a custom fog volume effect?

If it's just the environment settings, then I believe that's the same as the default pipeline, RenderSettings.fogColor

[fluid lily]

will test that

[sage latch]

Somehow I feel like my method is just stopping halfway through. I get the first log, but not the second one and it doesn't seem to return control to the caller either. It only happens after I reload the scene, maybe that has something to do with it?

    public void Initialize(GameSettings gameSettings, MapData map, IEnumerable<PlayerData> players) {
        Settings = gameSettings;
        
        Debug.Log("Loading map", this); // I get this log
        MapManager.Instance.LoadMap(map);
        
        Debug.Log("Creating players", this); // But not this one
        foreach (var playerData in players) {
            PlayerManager.CreatePlayer(playerData.Id, playerData.RobotData, playerData.Name);
        }
    }

There's no while loops or async functions involved

[fluid lily]

Well good news is that worked,,, bad news is that worked.

[quartz folio]

Is there an exception, and what's the contents of LoadMap?

[sage latch]

There's no exceptions
https://hatebin.com/njulqhgcnw

[quartz folio]

I don't see why that would happen. Have you tried following it through with the debugger?

[sage latch]

I'll see

Everything goes through

But no logs show up :/

[fluid lily]

The scene is using URP as the renderer, my textures are URP textuers, but my fog is default render settings.

[sage latch]

Also in the Game view it hasn't switched scenes yet, is that a problem? I'm calling this from OnNetworkSpawn on an in-scene placed NetworkBehaviour

[somber nacelle]

not a code question, but it looks like the rect is reversed

[ancient rock]

why not?

I mean, either you're targeting low-end devices (what URP is made for), of you're targeting high-end devices (what HDRP is made for).

[fluid lily]

The context is simply it's UX is very bad.

[ancient rock]

User Experience of URP is bad?

Not sure what UX is referring to here.

Because I've been using URP for my game and it seems fine to me.

[sage latch]

So invoking the method 2 seconds later fixed the issue

I guess the scene loading caused it

Nevermind, it broke again

[arctic marsh]

Morning everyone, hope you are having a good day and hope it treats you well.

So I have a bit of an issue, I did post this last night in #💻┃code-beginner but its been a solid amount of time since then and I feel this goes beyond starting level Unity, so here goes. Slight AR rubbish involved here too.

I am trying to get a pickup system working, like an inventory system. I decided to do the following.

a) Create a GameObject, titled Inventory, which has a list that can house ScriptableObjects.

b) The ScriptableObjects house the pickup data, such as type, effect value ect.

c) The pickup, has a component that houses all the possible items that item can add to the inventory.

The issue here, is when I try to Trace from my AR camera position, the Pickup tag objects are successfully detected, but I can't seem to successfully return any data from it. GetComponent or otherwise.

Here is the script I'm having problems with, specifically lines 58 through 100, I can definitely take a look at the rest of the setup if needed. NOTE: The debug messages are UI text, the game successfully detects what object was hit if its of the type "Pickup", it returns a standard "Hit" if nothing was hit. Line 93 doesn't overwrite the text to anything and therein lies my issue.

https://srcshare.io/641eb515ca97b4ee16cec26b

Many thanks in advance. Please let me know if there are any more details you need. I will get myself some breakfast 👍

(Debug.Log is not possible as I have to test the project on my phone. Using Unity Remote will not render my camera as a result.)

[cosmic rain]

There are many ways to see the logs from the build running on your phone.

Not just logs, you could even connect a debugger and step through the code with breakpoints.

[arctic marsh]

Hm, okay, interesting.

I've at least gotten it down to that area of line 58-100

Quite frankly I never want to do AR dev after this, ever again.

[cosmic rain]

You can see the logs by using logcat. Either as a part of android studio, separate app or a unity plugin. You could also just connect the editor console to the build.
To connect the debugger, you need a development build.

[arctic marsh]

Okay, thats useful. Thank you, I'll give that a proper look.

Do you have any possible ideas as to why Line 93 doesn't return anything?

[lucid valley]

the lines before it could be throwing

put in a try catch if you want to double check, can then log the exception to the touchDebug.text

[arctic marsh]

touchDebug.text = hit.collider.gameObject.name; works, after that point, I'm facing issues.

So we are definitely at least getting the object, just not its data.

[arctic marsh]

Okay, not used trycatch in a while, this'll be fun.

[cosmic rain]

Connect the console or see the logcat for wether there are errors thrown.

[cosmic rain]

You're debugging backwards.

Don't do that.

[arctic marsh]

Man, really wish I didn't have to set up more apps for a small assignment, but okay.

[cosmic rain]

It doesn't have to be an app. Use the logcat package for unity. That's the most convenient way.

And if that's too much for you, just connect your editor to the build and you'll see the logs in the console.

[arctic marsh]

When I do build and run, I need to use the development option then? I'll try logcat first.

[cosmic rain]

Yes. But logcat is a better option.👍

[arctic marsh]

Ok, lets see if this reveals anything, probably not though, GetComponent really annoys me at times.

[sick minnow]

Hi!

I am trying to add steam achivements to my Unity game (Don't know if this is the right place to ask, but couldn't find any other place - sorry)

I tried making this basic script: https://pastebin.com/3pMfzWvX

but I get the erros that SteamUserStats does not contain a definition for Get and SetAchivement

[lucid valley]

look at line 26

Steamworks.SteamUserStats

line 27 and 28 are just SteamUserStats

so try Steamworks.SteamUserStats there instead

uh, actually you have the using statement

humm, strange

[sick minnow]

yeah, I tried that now, but I get the same errors 🤔

[lucid valley]

oh, lol spelling error

achievement is spelt wrong

forgot the first e

[arctic marsh]

Okay, so theres an error as far as the game trying to add an item to a list is concerned. How do I properly add stuff to one during runtime?

[sick minnow]

oh, lol

lol, that fixed it 😆

thanks @lucid valley 🙂

[lucid valley]

with .Add()

[arctic marsh]

lmao I was trying to use Insert. I assume that if something errors the proceeding lines of code wont work either?

That would explain a lot.

[lucid valley]

yup

[arctic marsh]

If this works I will be happy and also kinda seething.

my fking god. Thank you @lucid valley

[ruby fulcrum]

how do i get the time elapsed since the previous while loop iteration in a coroutine

[quartz folio]

if you're just yielding null then that's the difference between frames, Time.deltaTime

[ruby fulcrum]

ohhh

so thats why its not doing it right i forgot to put yield

ok ty

so basically

if i put yield return null in a while loop coroutine

it will yield the coroutine until the next frame begins?

[quartz folio]

yes

[ruby fulcrum]

i see

[ruby trellis]

Im trying to make a lock on UI for my space game like in the game outer wilds where it shows you the relative velocity of a planet relative towards the player but the code I've got right now only works when looking at the planet at a specific angle because the speed axis are global and not relative towards the player. Is there a way to fix that? The image is an example of what it looks like in outer wilds

    void Start()
    {
        lastPosition = targetTransform.position;
    }

    void FixedUpdate()
    {        
        Vector3 currentPosition = sunTransform.InverseTransformPoint(playerTransform.position);
        Vector3 targetPosition = sunTransform.InverseTransformPoint(targetTransform.position);

        Vector3 dist = currentPosition - targetPosition;

        if (lastPosition == Vector3.zero)
            lastPosition = dist;

        Vector3 diff = dist - lastPosition;
        Vector3 speed = diff / Time.deltaTime * 10000;
        lastPosition = dist;

        Debug.Log(currentPosition);

        // Stream the value of relative velocity to a UI text object
        velocityText.text = speed.z.ToString("0.000");


        Vector3 targetScreenPosition = Camera.main.WorldToScreenPoint(targetTransform.position);
        velocityText.rectTransform.position = new Vector3(targetScreenPosition.x, targetScreenPosition.y, 0);
        LockOuter.rectTransform.localPosition = new Vector3(speed.x, speed.y, 0);

        if (targetScreenPosition.z <= 0)
        {
            velocityText.gameObject.SetActive(false);
        }
        else
        {
            velocityText.gameObject.SetActive(true);
        }


        
    }

[worthy yoke]

Hello, how should i handle i/o threads in unity? Create .NET thread or event native thread from winapi?

[open lake]

bois

ladies and gentlemen

how do I compress images permanently

not just like a build thing

[tepid river]

Use rigidbody velocity, dont calculate it yourself

Subtract ship velocity from planet velocity => get relativevelocity. Then use dot product to cast it onto axis of choice

[hazy shell]

hey everyone, does anybody know why I keep getting this error or how to get rid of it?

[pine bronze]

hey guys, this isnt really that big of an issue but it really annoys me, whenever i jump, you can see that i go to the left/right slightly. idk if this can be fixed but it annoys me very much. here is my code:

private void Jump(InputAction.CallbackContext ctx)
    {
        if (grounded && canJump)
        {
            canJump = false;

            rb.velocity = new Vector3(rb.velocity.x, 0f, rb.velocity.y);

            rb.AddForce(transform.up * jumpForce, ForceMode.Impulse);

            Invoke(nameof(ResetJump), jumpCooldown);
        }
    }

[quartz folio]

your player doesn't happen to have a slightly weird rotation does it?

[hazy shell]

"rb.velocity = new Vector3(rb.velocity.x, 0f, rb.velocity.y);" you are setting your player's rb.velocity.z to their y velocity

[dense spear]

hey buddy!! I tried it and it works like a charm!! Thanks for that I have a small issue with this... so I have made the corners and set it as a child to the plane (just for debugging purposes) and I noticed that as I increase the size of the plane, the size of the frustum increases upto an extent and after a certain point, it starts rotating as well... is there anything to stop that? something like this in the video...

[languid quarry]

any ideas on how to launch a separate .exe file from a game? my goal is to make a game launcher, essentially.

here's what I have so far

however it throws a "mono io layer" error, and after digging around the forums for the past 2 hours ive yet to find a fix for that.

[simple egret]

Might not fix your issue, but just for safety you should be using Path.Combine() to join paths, instead of using string concatenation with +

You might be passing a path that looks like this right now path/to//file.txt and that's definitely invalid

Say if dataPath ends with a slash

[languid quarry]

i've never worked with something like that. could you please share the syntax on how I'd use Path.Combine?

string good = Path.Combine(path1, path2)

[languid quarry]

thanks

[simple egret]

(you can pass more than two arguments if needed)

[languid quarry]

got it working now. it turns out the issue was me using a shortcut file to navigate to the correct executable inside another folder

combining the path instead of using the shortcut works. turns out they break after building or whatever

[ruby trellis]

Thanks, Ill try doing that with my caulculated velocities, I would do it with rigidbodys but the planet needs a non convex mesh collider which doesent work with rigidbodies

[sick minnow]

I have this code (the sample code for FPController), and everything works fine in the Editor, but when I export the project, I can't look up and down. Does anyone know why?

https://pastebin.com/H7kubbM3

[tepid charm]

just coded a pretty complicated algorithm for determining which soldiers in an army are in combat and who they are fighting, and it actually worked first try

crazy

[languid quarry]

im proud of you shrek

[wary wagon]

Im making a property editor for the inspector, for dictionaries. I want for each value of the dictionary, use the default property editor to render them . How can i do that ?

[leaden ice]

Why not just use one of the many existing serializable dictionary solutions out there

Or just make a list of key value structs

[wary wagon]

You have one to recommand ?

I adopted one long ago but it has no editors ;D

[leaden ice]

I would just be googling it and taking the first result

[wary wagon]

oh wait im dumb i didnt import the ditor at the time because i didnt know what it was

Hey guys, so i have poroblem when build my game in webgl. It wont call my API requsts, but in unity editor mode it works perfectly.
Any ideas on what could be? Can it be something in Player Settings when try to build game?

[west sparrow]

What did you use to make the requests? Unitys WebGL can't use some network functions, so you usually end up using BestHTTP. I believe normal C# web requests don't work? Sockets don't. But you can use Unity Web Requests.

I'd also give this a read, because cors, and http vs https

https://answers.unity.com/questions/1598212/unitywebrequest-not-working-in-webgl-build.html

And this
https://docs.unity3d.com/Manual/webgl-networking.html

[empty gust]

I tryed with Coroutines than tryed with async functions nothing work on build but in editor works fine

[west sparrow]

Yup, read the above

[empty gust]

hmm...on forum its saying like my url trying to access http but i defined url that starts with https

[tepid river]

your planet is not convex? :S isnt it a sphere?

[ruby trellis]

It has terrain so its sadly concave

[tepid river]

but why would that stop you from using rigidbody phyisc?

cant you just attach the terrain to a child object?

[ruby trellis]

Does that work

[tepid river]

not sure, i never had the issue. but i would assume so

its just that "my collider is not convex so i have to build my own phsx simulation" doesnt sound right to me 😄

[ruby trellis]

Well sadly that is sometimes jow unity is

One limitation so you have to do ever,thing from scratch

[elfin tree]

Hi, I'm trying to make it so moving the mouse around the screen slightly moves the camera towards the cursor, but with bounds, or could be just one value uniform across all directions screen. I'm not quite sure how to search for this but I'm sure this has been done before online, how can I go about this or search for this, thanks!

[shut elm]

Hey, I have got an question, when I do this, "y" never reaches 50 (because of y < noiseTexHeight, which is how it should work).
for (int y = 0; y < noiseTexHeight; y++) { float yCoord = yOrg + y / heightscale; int ytimeswidth = y * noiseTexWidth; if (ytimeswidth == 2500) { Debug.Log($"y{y},wi{noiseTexWidth}"); } for (int x = 0; x < noiseTexWidth; x++) { float xCoord = xOrg + x / widthscale; float sample = Mathf.PerlinNoise(xCoord, yCoord) * 255; byte samplebyte = (byte)sample; pix[ytimeswidth + x] = new Color32(samplebyte, samplebyte, samplebyte, 1); } }

But when I execute that code async "y" somehow reaches 50, why is that? There is in my opinion nothing that should affect y in that lines...

Task[] tasks = new Task[noiseTexHeight]; for (int y = 0; y < noiseTexHeight; y++) { tasks[y] = Task.Run(delegate { float yCoord = yOrg + y / heightscale; int ytimeswidth = y * noiseTexWidth; Task[] innertasks = new Task[noiseTexWidth]; for (int x = 0; x < noiseTexWidth; x++) { innertasks[x] = Task.Run(delegate { float xCoord = xOrg + x / widthscale; float sample = Mathf.PerlinNoise(xCoord, yCoord) * 255; byte samplebyte = (byte)sample; pix[ytimeswidth + x] = new Color32(samplebyte, samplebyte, samplebyte, 1); }); } Task.WaitAll(innertasks); }); } Task.WaitAll(tasks);

[leaden ice]

not entirely sure but that code seems like a race condition since you're incrementing y in a different thread than you're consuming it

this loop is going to happily run: for (int y = 0; y < noiseTexHeight; y++)
while the other threads are trying to read it:
float yCoord = yOrg + y / heightscale;

I think you'd want to make a copy for each of your delegates

like int yCopy = y; then use that yCopy in the delegate

otherwise they're all readying that same y variable

A question about simulating FOVs:

For class, my team is creating a 2D stealth platformer (not top down). I'm in charge of enemyAI, which includes movement and detection. So far, I followed Sebastian Lague's enemy FOV tutorial and it has served as a pretty good base. A very important part of our gameplay is that we want our character to be able to crouch behind objects in order to not be seen by the enemy. I have achieved this by having two capsule colliders of different heights and activating and deactivating them with button inputs (this part works great).

At first, I could not get Lague's method to work for our idea because the raycast he uses to check if there are obstacles in the way was drawn from the center of the enemies view to the center of the player's collider, and would inevitably collide with an obstacle if the center of the player's collider was even a bit lower than the object, while the rest of the collider was theoretically visible to the enemy. I "fixed" this issue by putting a circle collider on the top of the players head. This worked okay, except for the fact that if the player climbed on top of an object and said circle collider was outside of the enemies FOV, then the enemy would stop detecting the player, regardless of the body being inside the FOV.

My question is: would there be a way to cast various rays within the angle of the enemies FOV to detect the player collider regardless of if the center is being obstructed? Or, in the case of this method being highly inefficient, is there a better way to do this? I'm kinda lost and I want to get this done and working before starting with the enemy AI since this is a very important part of the gameplay.

Here is a link of the tutorial I am referencing, it should take you to the part where the code is complete https://youtu.be/rQG9aUWarwE?list=PLFt_AvWsXl0dohbtVgHDNmgZV_UY7xZv7&t=1213. If you would like to see my code, I can also include a snippet of that.

[tepid river]

i cant tell where your error comes from, but this whole code looks like it wants to be a shader.

[shut elm]

ohh yeah thank you. Works fine when using a seperate variable

[tepid river]

you can sample the area of the player.
just from the top of my head i would sample random points inside the players boundingbox and cast maybe 5 rays towards the enemies eyes.
if any of them hit, enemy has detected the player

if your player has a simple geometry, sampling points inside it is even easier.

[teal silo]

Just to see if I'm understanding correctly, you would cast the rays from the players bouding box? Or could it be done from the enemies eyes to the players bouding box?

[tepid river]

doesnt matter i guess, if it intersects, it intersects

[shut elm]

I've got another question. Why is the syncronous code running more than 170 times faster than running the multithreated code?

[leaden ice]

Sometimes the overhead of starting threads and coordinating them outweighs the gains you get from paralellization

although it's also possible your code is flawed in some way

I didn't read it too closely

[teal silo]

Gotcha. How would you personally determine which random points to cast towards? Do I just use the size of the bounding box (in this case a capsule collider) and divide accordingly, or is there some other way?

[tepid river]

hm something like Random.sampleUnitSphere and then multiply with the bounding box dimensions i guess
add a * 0.75 to scale the points to 75% so its not just inside the BBX but most likely also inside the geometry?

you could also have a couple fixed points so its easier to debug

[teal silo]

Yeah, I guess this is similar to how I used the circle collider at the top of the head as a workaround. I'll see if this could work.

[teal silo]

And I'll read up on the sampleUnitSphere since I hadn't heard of it before

[tepid river]

its a static method of unity Random iirc

or vector3, one of them

[teal silo]

Thanks for the suggestions and the clarifying drawing, I'll see if these methods solve my problem :)

[tepid river]

its a common problem. in early Arma 3, you could hide behind street signs, bc it would hide your face from the enemy

[teal silo]

Hah! I didn't know that, and I've played Arma3 quite a bit. It's good to know that it's not just me being a beginner

[tepid river]

flipside is, now it can detect you when it sees like your elbow through the foliage and laser-nuke you through the bush

🤷‍♂️

i guess an improved approach might be randomly sampling rays and counting up how many return "can see".
and then have a threshold after which the AI descides "yeah ive seen like 50 of 100 samples, im pretty sure i can see the player"
edit "ive seen this elbow now 50 times, time to nuke the playyer" lol

[teal silo]

Thats another good idea. What I had thought is to cast multiple rays from the center of the enemies view to different points along the external radius of the FOV, all contained within the angle of the FOV. But I have a feeling I'm going to need math for that and I suck at math, so we'll see.

[tepid river]

i wouldnt randomly cast to somewhere in FOV. instead, directly cast onto the interesting objects and test if they are visible

the probablity to detect something if you just cast to a single ray fixed to your enemies rotation are very slim.

it might make sense for movement tho

[teal silo]

Yeah, thats true. Then I'll probably try what you mentioned earlier of casting to points of the bounding box.

[tepid river]

if your game has few enemies/players, you can probably go a bit crazy on detection performance.

[teal silo]

Only the one player, and a couple of enemies scattered around different levels, since it's also supposed to be a platformer

[cedar egret]

how would I store unique data on each tile using tilemaps?

[mystic ferry]

I believe you would have each tile represented with a scriptable object

could be wrong though

[cedar egret]

GameObject?

[mystic ferry]

https://docs.unity3d.com/Manual/class-ScriptableObject.html

[cedar egret]

alright

But how would that work Tilemaps?

I assign that object to

each tilebase?

[mystic ferry]

not sure, I haven’t worked with something like that before

sorry

[cedar egret]

ah np

[mystic ferry]

I think codemonkey has a heatmap video that might be of some use

[upper pond]

how do i calcualte the angle a 2D gameObject is moving in? ive been searching the internet for about an hour with no avail

[cedar egret]

wdym calculate the angle

[upper pond]

say a Gameobject moved directly from left to right, the angle that it is moving at would be 90 degrees, or bottom left to top right, the angle would be 45 degrees

[cedar egret]

if u have an input

like

[upper pond]

wasd?

[cedar egret]

Vector2 input = new Vector2(horizontalInput, verticalInput);
float angle = Mathf.Atan2(input.y, input.x)

i think

[mystic ferry]

angle on the transform is a local space angle, but there’s a readonly worldspace angle on the transform called transform.lossyScale

[cedar egret]

other way

[upper pond]

take your time

[mystic ferry]

there’s also Vector3.Angle for between two objects

[cedar egret]

try this

[upper pond]

could i make an empty follow the target object with an offset and use vector3.angle?

[cedar egret]

atan2 should work

[mystic ferry]

what’s wrong with MoveToward()?

Then there’s Vector3.Lookat or something like that to line up normals

[cedar egret]

@upper pond did u try it?

[upper pond]

im editing the variables rn

[upper pond]

when i turn it into a public float the angle is just saying 0

[jagged laurel]

float horizontalInput = Input.GetAxisRaw("Horizontal");
float verticalInput = Input.GetAxisRaw("Vertical");
Vector2 input = new Vector2(horizontalInput, verticalInput);
float angle = Mathf.Atan2(input.y, input.x);

[harsh pasture]

Hello, I've been looking into the Strange IoC package. It's fairly old and hasn't seen any updates in awhile. Is it still relevant in Unity dev today?

[ashen yoke]

there is extenject and other maintained libraries

[upper pond]

the angle is just displaying 0

[thorny onyx]

    {
        for(int i = 10; i > 0; i--)
        {
            yield return new WaitForSeconds(1f);
            speedCountdown.text = i.ToString();
            if(i == 7)
            {
                DefaultSpeed = 1;
            }
        }
        
    }```

how can i fit a loop into a corountine like this

or do i just have to manually type it out

maybe i can declare i outside

[ashen yoke]

dont understand what youre asking, the code is valid

[elfin tree]

I'd like to compare two Quaternions after using Slerp to dermine if the rotation is finished, with a margin of error, how? RESOLVED

[steep herald]

Is there a way to manually iterate over a shader variants collection?

[plucky karma]

I wonder - has anyone managed to invoke Rustc lib inside Unity, and any pro/con doing this other than malloc for CAPI calls?

[tepid charm]

any idea why a quintuple nested loop would cause 170ms garbage collector frame spikes?

[dim spindle]

Could you please post the code mentioned?

Also have you for sure narrowed it down to this loop

Btw the reason you should post the code is because there are a LOT of reasons why that could happen

[plucky karma]

wait, a quintuple loop?

[tepid charm]

        for (int i = 0; i < sideTiles; i++)
        {
            for (int j = 0; j < sideTiles; j++)

                foreach (Soldier soldier in buckets[i, j]) 
                {
                    
                    for (int x = -2; x < 2; x++)

[plucky karma]

foreach is probably what's generating garbage collection...

[tepid charm]

yeah probably

[plucky karma]

and good god man.. Why so many loops?

[tepid charm]

I'll swap it out, 1 sec

[tepid charm]

I'm making a battle simulator, so I sort all soldiers into a grid in order to do checks between them

[vagrant blade]

Possibly that Linq line

[tepid charm]

hmm I was suspicious of it too but I couldn't be bothered to find a better alternative

[plucky karma]

Yup, Linq will most definitely allocate garbage!

[vagrant blade]

Now you can be bothered to!

[plucky karma]

Why do you need them in order? I don't see a reason why?

[tepid charm]

to find the closest

[plucky karma]

Why?

[vagrant blade]

Picking targets likely

[tepid charm]

because each soldier finds the closest enemy as a target

yeah

[plucky karma]

Would consider relying on physics cast instead of checking distance?

[tepid charm]

oof no

for some context, this is a prototype I started working on yesterday, it's a total war-esque game and this is my 6th attempt at making one

I always run into a brick wall of performance issues

so trust me, I've tried most things I could think of lol

[somber nacelle]

well checking distance against every single enemy is going to be much less performant than a spatial query like an overlap box and just getting the closest object from that

[plucky karma]

There's always some things you can try, but multiple for loop is never one of them. It's prone to have problems and can bottomneck your performance in unity at runtime.

[tepid charm]

....which is what I'm doing

[vagrant blade]

There must be something like GDC talks on the subject

[plucky karma]

In fact, all of this is on main thread, talk about halting your program for a sec here.

[vagrant blade]

Dots would be a good usecase here yes

[tepid charm]

I've tried learning DOTS twice

but I can never figure it out

[somber nacelle]

you just said "oof no" to a suggestion of using some cast/query though

[tepid charm]

I said oof to using unity physics for it

[cedar egret]

it shouldnt be

[somber nacelle]

"physics cast" referring to the same thing i was referring to

[tepid charm]

alright, I misunderstood then

anyway keep in mind this is the 1st iteration code, I haven't really optimized it yet, just trying to work through the biggest issues first

so I'll try to find an alternative to the Linq and swap out the foreach loops

[blissful whale]

Is there a command like this but will not work when it is held

[tepid charm]

GetKeyDown

[blissful whale]

yep that one, thanks

[upper pond]

when displayed as a float it says 0. is there any variables i needed to make?

[upper pond]

im a dubass. I put all the code into a void but didnt call it anywhere

[tepid charm]

happens to me about 7 times a day

[plucky karma]

C# isn't easy to learn guys... It's ok, but you're learning. That's the important part!

Not as bad as writing C, but hey, you get to deal with garbage collector 😄

[thorny onyx]

anyone know what this means

[somber nacelle]

you have code that isn't inside of a class

[thorny onyx]

yeah thats what i thought

nothing is outside tho

nvm

sorry

i had brackets outside

thanks

[crystal creek]

does anyone here understand the discord game sdk? ive gotten most of it working but when i send a game invite for my game in discord i get this

[buoyant mural]

Who are you sending it to

[crystal creek]

literally anywhere, even in my own servers

[buoyant mural]

oh

[crystal creek]

i do have permissions to send it

i can send it for other games

[buoyant mural]

Your application might not have permissions

Check the Discord Application

In Developer portal

[crystal creek]

where do you give it permissions???

[buoyant mural]

In general information I think let me see real quick

[crystal creek]

i dont see anything

[buoyant mural]

Ok wait I'll check rn

I think you need a Authorization link

in Oauth2

[crystal creek]

uh... now im confused what to do because i need a redirect url

[buoyant mural]

Ah can I see your invite code?

[crystal creek]

nvm hang on

[buoyant mural]

You will need a redirect url

I think I used my IP

before I forgot honestly

@crystal creek Use this
http://127.0.0.1

[crystal creek]

what scopes do i need

[buoyant mural]

rpc

This should allow your application to access your discord client if I'm correct

[crystal creek]

hm

[buoyant mural]

Also In OAuth2 add in redirects the same link

[crystal creek]

yeah still no

it just sent me to this in my browser

[buoyant mural]

Show me your invite code

as I said before

it must be a problem from your code itself

[crystal creek]

u mean the generated URL?

[buoyant mural]

The code for the invite

like

[crystal creek]

also prob better to move this to dms

[buoyant mural]

ok

yeah

[severe coral]

How would I cache reflection results (through the editor ) to quickly be able to access a field from any instance of a class at runtime?

Also could I use TypeCache for this, and if so how fast would it be?

[candid kiln]

how can i play a sound for each particle's birth in my particle system?

[plucky karma]

using static will preserve your result at editor-time. However beware about unity's domain refresh option!

[severe coral]

I need the cached field info to be non-static, and it appears the domain refresh applies for all scripts, when I only want to do this for a select few.

[ember coral]

if(isGrounded) {
    elapsedInAir = 0;
    hasJumped = false;
} else {
    elapsedInAir += Time.deltaTime;
}

if(Input.GetKeyDown(KeyCode.Space)) {
    jumpBufferCounter = jumpBuffer;
} else {
    jumpBufferCounter -= Time.deltaTime;
}

if(isGrounded) {
    
    if(jumpBufferCounter > 0) {
        rb.velocity = new Vector2(rb.velocity.x,jumpForce);
    }
} else if (elapsedInAir < coyoteTime && !hasJumped) {
    if(Input.GetKeyDown(KeyCode.Space) ) {
        rb.velocity = new Vector2(rb.velocity.x,jumpForce);
    }
}

if(Input.GetKeyUp(KeyCode.Space) && rb.velocity.y > 0) {
    hasJumped = true;
    rb.velocity = new Vector2(rb.velocity.x,rb.velocity.y / 2);
}```

I have this code for jumping the problem is that has coyote time and input buffering the only problem is that you also jump as high as you leave pressed and that dosnt work quite right with this input buffer

[dim spindle]

whats the context?

[ember coral]

I want to take how long you pressed and after that time passed stop jumping

[slow grove]

Hey guys, I'm building a large game that requires moving/rotating the world around the player, only issue is that the illusion of movement is broken since the skybox doesn't rotate. What would be a possible solution? I was thinking maybe making a fake skybox and rotating that, or possibly something involving one camera to render the scene and one to render the skybox maybe?

[eternal geyser]

guys i got a big problem

i am really hard struggling with a code

[sleek heath]

for the one line if statements, you can remove the braces

[ember coral]

I know

[eternal geyser]

public static void Main()
{
      public void Start()
    {
        HouseKey = GameObject.Find("HouseKey");
    }

    public void Update()
    {
        Debug.Log(HouseKey);
    }

}

[ember coral]

But somehow for me it maintains my code cleaner

[eternal geyser]

i cant find that specific object because i switch between scenes and come later to that old one

the object is deactivated

[eternal geyser]

this is why i cant do public and assign it

its like impossible

[hot yacht]

i don't understand your question or your purpose but, that's StartMethod by the time you click Play Button on unity, it will start search the HouseKey, Run only Once.

[eternal geyser]

even if i put it in update the search for gameobject the same error occures that the following gameobject does not exist or is not assigned

and i know why, its because its deactivated, it needs to be deactivated because if want to use an system where i can just turn on and deactivate the gameobject

I am for the first time at an point where i have no conclusion what to do

i dont know if i need to use instantiate, maybe thats better

[buoyant mural]

Hello I'm having a problem with this, yaw becomes -0.002f for a frame then 0 the other frame, why is this happening?

        private IEnumerator Rotate(bool negative)
        {
            if (negative)
            {
                yaw -= 0.002f;
                yield return new WaitForSeconds(1f);
                yaw = 0f;
                yield return new WaitForSeconds(1f);
            }
            else
            {
                yaw += 0.002f;
                yield return new WaitForSeconds(1f);
                yaw = 0f;
                yield return new WaitForSeconds(1f);
            }
            yield return null;
        }```

It's not waiting for 1 second

(I have a feeling I'm using this completely wrong)

[rain minnow]

Did you place logs before and after the yield for 1 second?

[buoyant mural]

No

[eternal geyser]

what is that supposed to be?

[buoyant mural]

Well I want decrease yaw for a second then put it back to 0 then wait again and repeat
