[elder hearth]

Well can be

[sour fulcrum]

i have many potential flood points

[elder hearth]

depends on what you are doing

[sonic harbor]

i want to create my own gen ai and agents

what's needed for that

[elder hearth]

Maths, advanced maths

[sour fulcrum]

actually would i even add 7 in this example or would i only add neighbours i've "passed"?

[elder hearth]

for gen AI you need to be very good at maths

[sour fulcrum]

please go somewhere else

[polar acorn]

Again, some basic reading would be a good idea.

This is a server for Unity development. None of this is Unity.

[sonic harbor]

physics too? and chem?

[verbal dome]

Pretty sure that when you add an unvisited neighbor to the stack (or queue), you can mark it as visited/explored right away

[naive pawn]

i was thinking before the foreach. you'll get duplicates either way, but the order of duplicates would be different

i think it's better in one iteration and worse in another? i haven't thought about this kind of thing in a long time and tbh i need to stop procrastinating 😓

[sonic harbor]

im kind doubtful so uk

[elder hearth]

Dude unless you are gonna take this seriously please go find someone else to harrass with this. And again wrong server

[sonic harbor]

uhm sry i didn't meant to harrass u , but im rly new to these things

[verbal dome]

Please stop flooding this channel with this unrelated convo. There are people being actively helped here. Go somewhere else (other server)

[naive pawn]

@sour fulcrum it seems like you had a question but it kinda got lost

what was your question, also are you going for breadth-first or depth-first

[elder hearth]

We've said a different server or at least a different channel. And someone is trying to get help with something

[sour fulcrum]

that question is new to me so i'm not sure, give me a sec ill give a bit more context

[sonic harbor]

uhm i will be getting on street in next 4 months if i dont pay my debt so it would be very kind of you if u let me clear my doubts

[night raptor]

It would be very kind of you if you did that elsewhere

[sonic harbor]

im trying to get help too but this is the only server i found

[elder hearth]

Agreed

[elder hearth]

Dude go find a different server, I can DM you some I know.

[sonic harbor]

alright i will go , thanks

[naive pawn]

assuming for each tile you go NESW, starting from 3, assuming 11 is blocked(?), would you expect it to go
3 4 8 12 7 6 10 9 5 0 1
or
3 4 7 1 8 6 0 12 10 5 9

[night raptor]

You won't get duplicates on the stack if the explored cells are marked as such right after adding them to the stack. It is just matter of whether to add cells to the stack that might be duplicates or just ignore them immediately if they are.

[sour fulcrum]

ok so i have these tiles, and i have them like voxelised into a little grid right.

the voxels that aren't being drawn in are "uninitalized" right now (just an enum). I need to flood this space in a way where the green floods into the uninitialized voxels (apologies if i'm misusing a term or something)

I guess the problem im running into based on how yall are responding is that my flood points are pretty varied and inconsistent in placement

[naive pawn]

don't you usually mark cells as explored when you, yknow, explore them? you didn't include that in the pseudocode

[sonic harbor]

DO YOU NEED A LAPTOP TO GET STARTED WITH CODING AND UNITY PROJECT

[sour fulcrum]

can you just fuck off

[polar acorn]

<@&502884371011731486>

[verbal dome]

They are guaranteed to be explored in the future, so might as well mark them explored when queuing them

[naive pawn]

be courteous. don't spam all caps and bold.

but no, you don't need specifically a laptop.

[verbal dome]

So you can avoid doing the extra check after dequeuing/popping from the stack

[sonic harbor]

thnx i will get everything started pretty soon enough

[frosty hound]

Is there an actual question here?

Obviously you need a computer of some sort to get started with Unity.

[naive pawn]

that's a good point, i don't think i've gone through that process

[sonic harbor]

ohk thanks for your help

[elder hearth]

Is there a way to speed up Vector3.MoveTowards?

transform.localPosition = Vector3.MoveTowards(this.gameObject.transform.localPosition, Vector3.zero, Time.deltaTime);
``` hers the code I'm using(it is in fixedUpdate)

[naive pawn]

increase the max delta

multiply Time.deltaTime by the desired speed

[night raptor]

Should have added that true. Thought there are many ways to do it so chose to leave it out of the pseudocode. I can edit it there

[polar acorn]

The third parameter is the max amount you want to move in one step

Increase that

[naive pawn]

right now you have a hardcoded speed of 1

[elder hearth]

Okay thanks a lot!

[naive pawn]

damn, i refunded my tech skill tree and took everything out of competitive programming...

[elder hearth]

Please do not use that abbreviation LMAOO

[naive pawn]

oh, yeah

[elder hearth]

xDDD

[elder hearth]

What's the oppisite of hardcoded? Softcoded? Idk softcoded sounds weird

[naive pawn]

variable (adjective)

[elder hearth]

Ahhhh thought so

[night raptor]

So what is the point of the flooding? Find every cell (directly or indirectly) connected to the green cells and change their enum state?

[sour fulcrum]

yes

maybe my brain was using the term too literally vs programmically

imagine like literal flooding

[night raptor]

And the yellow ones presumably work as boundaries for the flooding? You don't want any liquid sim (or flooding animation) happening there though do you?

[sour fulcrum]

correct, but the work is already done there so-to-speak in the sense that this flooding would just be checking if current voxel is green then "somehow" making any white/empty tiles green (via the solutions we've been talking about)

yeah nothing fancy nor realtime, this isn't for actual flooding 😅

[elder hearth]

I multiplied it by 0.5f it is somehow slower

[naive pawn]

you made it slower and it's.. slower now?

what did you expect

[elder hearth]

My brain kinda just forgot the math

maybe i should get some proper rest lol

[naive pawn]

lower number = lower speed

deltaTime * 0.5 < deltaTime (deltaTime > 0)

[elder hearth]

I realised that now lol

[naive pawn]

MoveTowards takes a max delta
if you have a deltaTime of 0.1 and a speed of 2, if you multiply those together, you get 0.2, the amount to move in 1 frame
deltaTime = 0.1 --> 10fps, so with 10 frames (1 second), you move by 2 (matching that initial speed)

[verbal dome]

Also @sour fulcrum this might be a good usecase for a Job, but make it work first, jobify it later

[elder hearth]

I might just make into a spring joint, i think that would be better for a REPO-like grab system

[night raptor]

Ok. So what you could do is start by finding all the green cells, marking them as explored and adding all of them to the stack/queue. Then you can start running this #💻┃code-beginner message algorithm by going through every element in the stack and adding all the neighbours which are not yet explored to the stack/queue (you would also not want to add yellow cells there).

Assuming that you have easy access to the state of each cell, you don't need to keep track of the explored cells separately, instead you can turn each cell to green immediately in the foreach loop if it is unexplored (not green or yellow) and you can then treat cell explored if it is green by color (or whatever state the green color indicates in your case). The whatever structure you have for the cells (3d array?) would serve the purpose of the bitset Chris mentioned here #💻┃code-beginner message

[sour fulcrum]

thank you very much, i appreciate the time and advice a lot 🙏

ill let you know how it goes

[night raptor]

No problem. Feel free to ask if anything is unclear. Note that I wrote the pseudocodes from memory, they are not tested to work. You can google iterative BFS/DFS implementations to find a lot of similar solutions (filling and searching is very similar in nature). Once you get it implemented, you can try changing the stack to a queue or other way around and see if it affects the performance. Using stack makes it depth-first and queue makes it breath-first

One important considerations is also how many ways you want to search from a given voxel. The less is more efficient but you need to do more if you need the fill to snug through corners or edges. The flood fill wikipedia page has a nice visualization of the effect in 2D with 4-way and 8-way fills. In 3D, you can do 6-way, 18-way or 26-way fills. Looking at the image you send of your level, 6-way fill is probably what you want

[night raptor]

Just for extra demonstration, I can go through this example assuming a 8-way (diagal neighbours also checked) breath-first implementation (queue) of the algorithm explained. So the algorithm would start by collecting all green cells and adding them to the queue which would then only be [ 3 ]. Then we would start the while loop which takes the 3 out of the queue and adds all the neighbours (which are white) of 3 to the queue and colors them green. The queue would now look like this [ 4, 8, 7, 6, 1 ]. Now 4 would be removed and nothing added since 4 does not have white neighbours anymore. The next iteration would remove 8 and add 12 and color it since that's the only white neighbour. Now the queue would look like this [ 7, 6, 1, 12 ]. At this point everything except 11, 10, 9, 5 and 0 are colored green.

7 has an unexplored neighbour 10 so that is added and colored. 6 has unexplored neighbours 9, 5 and 0 so those are added to the queue and colored green. Now the queue is as follows [ 1, 12, 9, 5, 0 ] and the whole room except 11 is colored green. The algorithm doesn't know that yet and goes through each of the cells in the queue removing them one by one, since it doesn't find any new unexplored (white) neighbours for any of them, the queue will become empty and the algorithm will terminate right there.

[elder hearth]

How performance heavy is adding and removing a component during runtime?

[frosty hound]

Impossible to say. Doing so is normal workflow though.

[elder hearth]

Ahh okay thanks

[frosty hound]

Though, if you're needing to do that, you might consider just using prefabs or prefabs variants. But it depends on what you're doing.

[swift crag]

yeah, give us some more details and we might be able to give more specific advice

[ionic zealot]

Hii, is it possible to have time scale affect particles?

[swift crag]

oh, interesting, i always figured that particle systems would respect your timescale

my first thought would be to write a script to handle that

just call it ParticleTimescaleHandler or something and have it set the simulation speed of the system

[short hazel]

By default it uses the regular delta time, but there's a check box to tell it to use unscaled delta time somewhere in its settings, if I remember correctly

[swift crag]

oh, yeah, then that should work fine

I looked at the settings, saw that property, and decided "oh, but that's not the timescale, that's delta time!"

[ionic zealot]

https://codeshare.io/5Dw7EW

My outputted reticle position does not at all match the position on canvas, but i have no idea why, can anyone please help me?

[naive pawn]

isn't the position there the anchoredPosition of the recttransform like i mentioned before

[ionic zealot]

I dont think so, cause then theres anchors, yk, but im not a remotely smart lad, so could be wrong

[naive pawn]

those are anchor positions, not the anchored position

https://docs.unity3d.com/ScriptReference/RectTransform-anchoredPosition.html

[swift crag]

The min/max anchors tell you how much you stretch based on the size of the parent RectTransform

it's the fraction that you, with a width/height of zero, try to occupy

(so, anchors of 0.5 mean you don't stretch at all!)

[naive pawn]

https://docs.unity3d.com/Packages/com.unity.ugui@2.6/manual/class-RectTransform.html

Pos (X, Y, Z): Position of the rectangle's pivot point relative to the anchors. The pivot point is the location around which the rectangle rotates.

[naive pawn]

the anchors being together is what makes it not stretch

[swift crag]

right, that's more accurate to say

my statement was the obnoxious kind of true 😉

[ionic zealot]

So, would anchored position save me then here maybe?

[naive pawn]

ive told you what, 4 times now to use anchoredPosition, haven't i?

[ionic zealot]

Well, yeah, but it just all kinda broke every time, so i keep trying to modify it enough for it to work

[naive pawn]

use anchoredPosition and make sure your anchors are set properly and make sure you're using anchoredPosition consistently.

[ionic zealot]

Nah yyea nah,it doesnt work, unity sucks sometimes

or ig i sucks at unity sometimes

[ivory bobcat]

What do you mean it doesn't work? Is there an error?

Are the values not what you'd expect? Anchored position.

[ionic zealot]

Yeah, the y pos is like 2-300 too high

[naive pawn]

compared to the value in the inspector, or compared to screenspace?

[ionic zealot]

Inspector

[ionic zealot]

It's on scaled, but its still not reacting at all, strange

[onyx ridge]

I'm following a tutorial and I'm really confused why the scoreboard is being referenced like this instead of with a [SerializeField] and then dragging it into the inspector? The reason the guy gave was

"There are a lot of different ways to get references inside Unity. We’re most familiar with using SerializeField and dragging objects into the Inspector, but in this case that’s probably not the best practice. A Scoreboard is currently a MonoBehaviour attached to a GameObject in the scene, while your enemies are prefabs — and from scene to scene those prefabs might not persist. You might even want to instantiate enemies at runtime, and they won’t be able to spawn with a SerializeField reference to a scene object. In that situation, it can be a good idea to obtain that reference in another way."

I don't really understand this explanation. Why wouldn't enemy be able to spawn with a SeralizeField reference to a scene object all of a sudden? I just don't see how scanning the entire project with FindFirstObjectByType<Scoreboard>() is better?

[solar hill]

"You might even want to instantiate enemies at runtime, and they won’t be able to spawn with a SerializeField reference to a scene object."

this is the exact reason why

[onyx ridge]

idk why I find this so confusing

So prefabs can reference other prefabs in [SerializeField] when instantiated but not objects in the scene?

[grand snow]

The person is basically demonstrating their lack of skill because this is a shit take

Finding objects by name/type should be done sparingly as its slow

[onyx ridge]

they did say that tbf

[solar hill]

think of it this way, how would you get a reference for that scene object in the prefab?

[grand snow]

The good way to overcome the issue is that the spawned objects get initialised and given the references needed

but thats not easy for beginners

[onyx ridge]

dragging it from hiearachry into the [SerializeField]?

[grand snow]

Most beginners of unity have no prior programming knowledge 🤷‍♂️

[solar hill]

have you tried it? you will be surprised

[sour fulcrum]

a prefab referencing something in the scene is like a boxed blender at walmart having a reference to the wall socket in your kitchen

[grand snow]

what are you smokin

[onyx ridge]

I haven't tried it because I was told it doesn't work, it just made logical sense to me but no point if it doesn't work I guess

[grand snow]

a scene object CAN reference a prefab and thus can give shit to instantiated stuff

[onyx ridge]

what if I just made the Scoreboard a prefab then referenced it that way in [SerializeField]

then they're both prefabs

[grand snow]

fuck it just read this https://unity.huh.how/references/prefabs-referencing-components

[onyx ridge]

So could I just make the Scoreboard a prefab and reference it through [SerializeField] that way to dodge the issue?

[grand snow]

The way to really solve the issue is to just setup what you spawn after is created

[SerializeField]
Enemy enemyPrefab;
//...
Enemy newEnemy = Instantiate(enemyPrefab);
newEnemy.Init(scoreboard, coolShit);

^imagine this is in a component already in your scene so it can serialize a ref to scoreboard

perhaps it could be named EnemySpawner ?

[onyx ridge]

Both Base Enemy and Scoreboard is in the Hiearachy but I wouldn't be able to drag Scoreboard into a [SerializField] on the Base Enemy because it's a prefab?

oh wait it's an instance of a prefab

[grand snow]

yes thats correct

[onyx ridge]

so it's also an object

[grand snow]

so these can just have a serialized ref

But an instantiated prefab would not and requires manual initalisation

[naive pawn]

prefabs are also objects (specifically gameobjects), just not scene objects

[grand snow]

everything is an System.Object

[onyx ridge]

but I have a [SerializeField] GameObject destroyed VFX but it's a prefab that I drag into the field so that's why that works?

[grand snow]

cus its a prefab ASSET

[onyx ridge]

But I wouldn't be able to do the same thing is Scoreboard because it's a game object in the scene?

[grand snow]

YES

think logically, how can a prefab asset possibly reference something in a scene when it may not even be loaded??

what happens if you tried to use that prefab in another scene?

[sour fulcrum]

(also just as a vibe check, this is a very big thing beginners "struggle" to learn so don't stress if it feels weird)

[grand snow]

Yea that is true. The important thing to understand is that when we "load" a scene unity just makes everything that was in the scene fresh

[onyx ridge]

Yea this is the first thing I've come across so far that I'm really struggling to understand, referencing things in different ways. So far it's just been a memory game apart from this

[grand snow]

An asset is different because its constant and the same and wont go anywhere

[onyx ridge]

so the reason we can't do it isn't "You might even want to instantiate enemies at runtime, and they won’t be able to spawn with a SerializeField reference to a scene object" But it's that we literally can't because unity doesn't let us even if we tried, and not because of something I 'might' want to do later on?

As in, it's not something I 'could' do now but 'shouldn't', it's that I literally can't because unity doesn't allow it?

[grand snow]

Its just not logically possible with unitys design

and thats fine and normal and expected

[solar hill]

its a bit of a catch 22

[grand snow]

It could be overcome but would be dumb and unreliable

[solar hill]

yeah even if possible, it wouldnt be advisable

[onyx ridge]

so scoreboard = FindFirstObjectByType<Scoreboard>(); is the best way to do it?

[grand snow]

no but just do that to learn how stuff works

you can learn better ways down the road

[onyx ridge]

It's really confusing trying to keep in mind how everything links together in scripts - inspector - prefabs - hierarchy

[onyx ridge]

Ok I'll trust the process 😌

Thanks for the help everyone 🙂

[placid solstice]

hello, im trying do a movement system for the camera, this error appears:

Movement.Update () (at Assets/Movement.cs:24)```

the line was is wrong is

```cs
GetTransform.Translate(new Vector3(horizontal, vertical, 0f) * Time.deltaTime * velocidade);

im sorry for dont have some description about the error

but, basically, the script what contains this line was used in a "Main Camera"

idk if have a problem about this

[ivory schooner]

Does anyone feel like helping me with understanding how to make a camera reset feature in a gyro experiment I'm working on? I have been at it for like a week and can't get it right. 🙁

[swift crag]

what does that entail?

[ivory schooner]

Talking to me?

[swift crag]

yes; what would a "camera reset feature" be?

[wintry quarry]

No...

[keen bridge]

thanks! 🙂

[minor pawn]

I really recommend you learn and fully understand this but here is what you probably ment to do:
https://pastes.dev/V9y2FPEXjW

"transform" is a built in variable inside all MonoBehaviours

[bold root]

Once I have a usable build what’s the normal pathway to trying it out and maybe publishing it privately so someone else can try it as well

[teal viper]

For trying it out, just launch the exe. Or "build and run". To share, just share the files of the build(might want to consider archiving the folder) in any way you desire.
There are some platforms that allow free publishing, like itch io, but I'm not sure if you can do it privately.

Also, this is not a coding question...

[keen bridge]

hey, is there a way to make this health bar centered? the only way I know how is to manually adjust it until it "looks right". Is there a button to do this automatically?

[timber tide]

rect transform? wat

oh you're using a world space UI right

[keen bridge]

yes that is correct

[timber tide]

Should just be able to center the pivot as you have it and zero out the coordinate space assuming the canvas is child to your character

and modify the y a bit manually

[keen bridge]

ahh 😅 thank you, i got it 🙂

[keen bridge]

Hello,

I am watching a youtube video for attacking other troops, the person has setup a trigger sphere so when a troop enters the collider it will set them as their target. He recently added the "OnTriggerStay" function, but kept the "OnTriggerEnter", but I'm not sure why. If the code in both stays the same, whats the point in keeping "OnTriggerEnter"? Unless im missing something it would be best to remove the OnTriggerEnter event?

    private void OnTriggerEnter(Collider other)
    {
        if(isPlayer && other.CompareTag("Enemy") && target == null)
        {
            target = other.transform;
        }
    }

    private void OnTriggerStay(Collider other)
    {
        if(isPlayer && other.CompareTag("Enemy") && target == null)
        {
            target = other.transform;
        }
    }

[stoic mural]

My first thought is that OnTriggerEnter is set the first location of the enemy

And the OnTriggerStay is updating of the enemy location if he still inside the trigger area

[keen bridge]

from my point of view OnTriggerEnter is not useful, as if it was removed then OnTriggerStay would set the target value anyway? Not sure if im missing something

[cosmic dagger]

it really depends on how you want to check for and assign the target. OnTriggerEnter will only run the check once when the object enters. OnTriggerStay will run the check every FixedUpdate . . .

[stoic mural]

Actually you are right, is not helpful you can remove OnTriggerEnter

[keen bridge]

he said he opted to use the stay event because if an enemy was killed whilst another enemy is in radius then the a new target would not be used, which i think makes sense
thank you for the clarification guys 🙂

[cosmic dagger]

if you only need to check once, then OnTriggerEnter is the better, more performant option. you can use OnTriggerExit to check if that enemy left the trigger, then set the target to null . . .

[stoic mural]

Better way to implement 👍🏻

• Enter = pick target quickly
• Stay = pick a new target already inside
• Exit = clear target when it leaves range

Do not take it as ultimate solution but to understand how it works

[cosmic dagger]

a better method is when an enemy enters the trigger, add them to a list. then choose a target by iterating the list and selecting the first one, or by distance. when an enemy leaves the trigger or dies, you simply remove them from the list. this avoids calling OnTriggerStay every FixedUpdate . . .

[fickle plume]

@stoic mural Don't post slop code here. If you don't have the answer don't delegate it to LLMs.

[keen bridge]

good idea! thank you.

is it possible to add descriptions to components?

Its not immediately clear that this is for "is troop in range", I imagine a troop could have many colliders, which could make it hard to know which one is for what.

[fickle plume]

You can put them on named game objects, or assign named unique physics materials with default values to differentiate.

[keen bridge]

so for the first option, id have
troop

• object named "in range collider" as a child of troop, with "sphere collider" attached to that, instead of the troop

[fickle plume]

events from children colliders should propagate to parents

Only 2d I think has weird behavior where collider placement matters for sorting layer when it's not on the object with renderer. 3d should be fine.

[keen bridge]

thank you 🙂

[wet pivot]

I'm very confused by the velocity change function force mode. I have a simple movement script here and the speed keeps going up if I keep pressing the move buttons.

` private void Update()
{
moveDirection = orientation.forward * inputManager.verticalMove + orientation.right * inputManager.horizontalMove;
}

private void FixedUpdate()
{
    MovePlayer();
}

private void MovePlayer()
{
    rb.AddForce(moveDirection.normalized, ForceMode.VelocityChange);
}`

Just for clarity, vertical/horizontalMove are the x and y axis of a joystick/WASD input and orientation is an empty object in the center of my player object to keep track of which way he is facing.

I thought velocity change forcemode instantly sets the movement speed to the first input vector, in this case moveDirection.normalized. If I'm using a normalized movement vector, shouldnt the velocity always be 1?

hmm documentation says "Add an instant velocity change to the rigidbody, ignoring its mass." so I guess it adds 1 unity of velocity to the rigidbody every frame?

[fickle plume]

In this mode it is pretty much the same thing as assigning velocity directly to the object, only through AddForce method. https://docs.unity3d.com/6000.0/Documentation/ScriptReference/ForceMode.VelocityChange.html
If you have anomalous behaviour you should check what else affects it.

[wet pivot]

hmmm should be nothing else affecting it unless I missed something, but I'll keep investigating.
So you're saying if I run "RigidBody.AddForce(10, ForceMode.VelocityChange)" should it consistently move at 10 velocity, or is it adding +10 to the velocity every time the function is called?

[fickle plume]

it just sets it to vector length

[wet pivot]

oh yeah u right 10 is not a vector3 XD. hm this is still weird unexpected behavior imma try it out in a scene by itself maybe something else in my scene is messing with the physics... or maybe the physics settings.

[keen dew]

AddForce will always add more velocity to that direction regardless of mode. If you want a specific velocity just set it directly

[wet pivot]

ah ok. I followed a pretty long tutorial series that used direct velocity changes, but the code got quite bloated and the direct velocity changes led to some issues that the youtuber fixed off-screen... and then another youtube tutorial said changing force directly is actually BAD and using addforce is better...

it seems he misrepresented how addforce actually works

I'm gonna just try to rebuild what I had before using direct velocity changes and just pay more attention to what I'm doing so I don't lose track of how it all works 😅

[fickle plume]

Oh yea, that's correct, don't know why I decided it doesn't, maybe tested long time ago with default friction.

[keen dew]

Neither of them is good or bad, they're just for different use cases. Setting velocity directly gives you snappy, instant movement but you have to manage it manually and adding more features like jumping and knockback is more difficult. AddForce gives you natural acceleration and deceleration and interaction with physics objects but you lose some control and you have to tweak it more to get it right

[wet pivot]

Yeah the tutorial series I was following got pretty bloated with features. Basic movement and jumping obviously, but wallrunning, wall climbing, dashing, sliding, ledge grabbing.

Some of them were direct velocity changes, but some stuff like the dash were impulse forces and sometimes the velocity would get set and override the added forces. Got really messy and hard to keep track of all the different conditions.

Sorry to ramble, but it's at least good to know that this is something that tends to cause issues when using rigidbody movement and it isn't just me being a complete noob.

[fickle plume]

I've only experimented briefly with physics based controller, but it absolutely possible to have a nice snappy physics based one. You usually want to increase gravity, and add linear damping and also control friction on surfaces depending on conditions. There's a lot of corner cases to handle but it's doable.

[wet pivot]

Yeah he makes a pretty sick rigid body parkour character controller by the end of the series ngl but again very bloated and confusing to navigate

my goal currently is to split it into different scripts and get a better grip on how and when it changes velocities so I can implement my own movement features without breaking everything

[bold root]

I just imported NGO and the unity multiplayer packages, but when i click start host i get this error and when I click start server i dont get any errors. Any idea what causes this? The error links to the default unity transport script. Not even sure where to go about debugging this

[unkempt adder]

Can anyone help me understand this code I found from a tutorial?

[ionic zealot]

enemy: (141.64, 99.92) reticle: (137.43, 94.11) Accuracy: 1462.082 I dont think that's right

float distance = Vector2.Distance(reticle.anchoredPosition, enemyLocalPos);```

This is the func

```c#
void ResolveShot(bool won)
    {
        Canvas canvas = reticle.GetComponentInParent<Canvas>();
        RectTransform canvasRect = canvas.transform as RectTransform;

        Vector2 enemyLocalPos;

        RectTransformUtility.ScreenPointToLocalPointInRectangle(
            canvasRect,
            cam.WorldToScreenPoint(enemyTarget.position),
            canvas.renderMode == RenderMode.ScreenSpaceOverlay ? null : cam,
            out enemyLocalPos
        );

        float distance = Vector2.Distance(reticle.anchoredPosition, enemyLocalPos);

        Debug.Log("Accuracy: " + distance);

        Time.timeScale = 1f;

        float hitThreshold = currentSize * 0.5f;

        if (won && distance < hitThreshold)
        {
            Debug.Log("You won");
            _enemy_anim.speed = 2f;
            _enemy_anim.SetTrigger("Die");
        }
        else
        {
            Debug.Log("You lost");
        }
    }

Please help me figure this bit out cause I am using anchored pos but its still breaking

I need a bit of a delay before the shot cause of the animation, but this is just broken

(full script) https://codeshare.io/5ZvkWN

[undone rampart]

why not just trigger the animation from the input and call the shooting logic from an animation event

[stoic mural]

is your code separated into difference files ? you can make the movement separate in file that call 'PlayerMovement.cs" to handle the player movement logic.

[stoic mural]

what type of game you making?

[elder hearth]

I was looking for hours to find the reason I couldn't jump after running into walls, turns out my sphere was too big...

[ionic zealot]

Oh nah, there aint a movement file, this is a duel

[ionic zealot]

Huh, that makes sense tbh

Mainly cause its a mixamo read only animation and i cant really add on

[undone rampart]

you can from the fbx file in the animation tab

or duplicate the animation file and it will create a writable copy

[ionic zealot]

Where?

[undone rampart]

in the import settings of the fbx

there is an animation tab

[ionic zealot]

Ohh i see

[undone rampart]

there should be an events foldout there

[open crater]

Guys what is a logic script? And how to figure out if the script im writing is logic or not

[frosty hound]

Where did you hear about a "logic" script?

By definition, every script you make contains "logic".

[open crater]

I mean when the script is a manager

[frosty hound]

Same question, where did you hear about that? And by definition every script contains logic.

What are you actually trying to achieve?

[red ivy]

Why is my physics.raycast detecting Collider_01 at some parts of the screen?

It doesnt really detect what it should

everything is Collider_01

[frosty hound]

Search for Collider_01 in your hierarchy and see what the object is?

Perhaps your raycast isn't starting or firing in the direction you think it is? Or it is, but it's being blocked by said collider?

[elder hearth]

This is the part of my movement script that is called in update

            Vector3 moveDirection =
            transform.right * CurrentMovementInput.x +
            transform.forward * CurrentMovementInput.y;

            if (moveDirection.magnitude > 1f)
                moveDirection.Normalize();

            transform.position += MoveSpeed * Time.deltaTime * moveDirection;
``` It clips into objects, how can I prevent this whitout adding any performance-heavy tasks?

[frosty hound]

You can't move objects with transform.position you're teleporting it. You need to use a rigidbody with actual physics.

[ionic zealot]

Hi, y'all, can anyone help me with this

'PlayerRigged (2)' AnimationEvent 'Shoot()' on animation 'mixamo.com' has no receiver! Are you missing a component?

I looked it up and i added a script onto the game object that just does this

using UnityEngine;

public class AnimationReceiver : MonoBehaviour
{
    public DuelSystem duel;

    public void Shoot()
    {
        duel.Shoot();
    }

    public void SpawnGun()
    {
        duel.SpawnGun();
    }

    public void RemoveGun()
    {
        duel.RemoveGun();
    }
}```

But still get the error, any ideas?

[red ivy]

Bro thanks. This was so obvious lol but i didnt check. Thanks for help

some fucking colliders were on the way

invisible wodoo crap

[elder hearth]

This is on a rigidbody, with actual physics. But would I call rigidbody.Move()? Or would I call rigidbody.AddForce()? I'd assume .AddForce since move requires a positon to move to, but I could be wrong

[frosty hound]

https://docs.unity3d.com/ScriptReference/Rigidbody.MovePosition.html

You're not using physics at all, if you're using transform.position

[elder hearth]

Oh yes I know but I was just saying this is on a rigidbody with physics

Also thanks for the help!

[wintry quarry]

which object has the Animator component

[polar acorn]

It's whatever you want it to be because that isn't an actual defined term

[polar acorn]

Is this script on the exact object that has the animator? Not a child or parent object but the exact object?

[stoic mural]

Still what type of game you try to build

Should you separate your Player movement into another script? And make method to handle the player and then the DualSystem script manage the dual interactive between the player and the enemy?

[turbid jolt]

how would i be able to have my tank move by itself as an enemy npc if anybody knows roughly, i also kind of need the turret to be able to shoot and etc by itself too seperately from the main body

i have the player version worked out

and ill add health damage after the movement parts

[wintry quarry]

you write a script to control it

it's a pretty vague question

[solar hill]

this is also multiple problems

and not one singular one

break it down first

[turbid jolt]

i see

[solar hill]

start with basic AI pathfinding first

[wintry quarry]

Almost certainly the stuff like health and damage etc should be common to both the player tank and the enemy tank. I would expect generally that the two tanks are almost identical except for a couple of components, e.g. "PlayerTankControl" vs "AITankControl" scripts

assuming they are meant to be the same physically other than who controls them

[turbid jolt]

yes

[stoic mural]

Untiy have what called NavMesh but you need to write AI to the tank “TankMovement.cs”

And “TurretHandler.cs”

[turbid jolt]

okay cool, ill try that out, i've kind of done some of the navmesh stuff trying to follow the free unity learn tutorial but that one is a bit too lenghty in the code

[turbid jolt]

okay i see ty

[stoic mural]

Happy to help ❤️

[pearl galleon]

hello i need i build a mobile app game the problem is the apk is installed but i cant open it i verified it its installed in the phone itself i tried everything using different project file and

• Confirmed it is not a Work Profile install (personal profile only).
• Confirmed Unity Package Name was set (you showed com.it7.cogniville in Player Settings at one point).
• Confirmed the Firebase Unity popup indicates your Firebase config contains com.cogniville.appname (and was missing com.it7.cogniville ), so you decided to use com.cogniville.appname .
• Confirmed your custom manifest includes the correct launcher intent on UnityPlayerActivity :
• android.intent.action.MAIN
• android.intent.category.LAUNCHER
• android:exported="true"
• File: AndroidManifest.xml
• Confirmed there is no Leanback/Android TV intent or feature declared in your Android plugin manifests (no LEANBACK_LAUNCHER etc.).
• Confirmed your UI reference resolution is already 1920x1080 (CanvasScaler)

[wintry quarry]

The big question is what happens when you try to run it? Use LogCat to check the logs.

[pearl galleon]

I can’t run it. It installs, but I can’t open it. The app doesn’t show up on my phone, and I can only see it as installed in Settings. There’s no Open button there either.

[wintry quarry]

how did you create the app

[pearl galleon]

by unity just clean build on android platform

[wintry quarry]

and how did you install it?

[pearl galleon]

by transfering the apk thru google drive to my phone and installing it in my file manager in the phone

[wintry quarry]

And something like this should launch it: adb shell monkey -p your.package.name -c android.intent.category.LAUNCHER 1 if not you're missing an appropriately configured Activity in the android manifest

[wintry quarry]

This is sideloading - you should use adb install or build and run through unity

[pearl galleon]

ohhh

ill let you know what happens then thank you

have a problem over here

my mesh moves when animation played

instead of an object

found the problem

its due to copy pasting having the same mesh

a bug of some sort

[placid solstice]

hello, in a Flappy Bird tutorial, i used a canvas from UI option when u right click in Hierarchy, but, the display now is soooooo big, is there a way to fix it?

the positions arrows are from a gameobject, in the normal size, if u see

the UI is so big

i am surprised cuz when u click in Game tab the game are normal

[frosty hound]

This isn't a coding question.

This is also how screen space UI works, it's not in the world. The white box you see in your first screenshot represents your screen, and those elements will be where on the screen they lie.

Hello everyone.
I'm kinda new in programming. I want to understand how to build system of destructions for environment like in Battelfield.
For now i only now that you can manually shatter object in Blender and than working with pieces in Unity, but its looks like very complex and not optimized. I saw in Unity Store asset that can do it with any object.

Can you give some advices in which way should i looking?

[keen dew]

Well you could use the asset you found.

It's a very advanced topic, so if you're new you might want to start with something simpler

Huh?
Did I send this here? I'm such an idiot

[wheat forum]

Hii, I am starting to write code I know what i need to do just have no idea how to write it, I kinda want a grappling hook like LittleBigPlanet,
I was thinking of using a LayerMask so i can choose what you can grapple to and a LineRenderer + DistanceJoint 2D to make it functional

[verbal dome]

About the layermask, what if you grapple something that can't be grappled? Should the grapple fail or should it go through that object?

[wheat forum]

it should just fail

[verbal dome]

Okay, then you can't use that layermask directly in the raycast (or whatever you use), otherwise it will just ignore things that can't be grappled

You can use it to check if the hit object was on the correct layer after you detect the hit, though

[wheat forum]

Imma be so fr i hadnt even thought of that

[verbal dome]

Other than that, linerenderer + joint would work yeah

Or manually adding forces/adjusting velocity of the rigidbody, instead of using a joint

[wheat forum]

the only thing i noticed is when i enable the joint and i start hanging the rigidbody loses momentum at the bottom

i think it has to do with how the movement i made works but i am not sure

https://pastes.dev/Aq3VZgQcNM

[verbal dome]

The issue is that you are overriding the velocity by setting rb.linearVelocity = ...

So the joint doesn't get to affect the velocity

How I solved it is use AddForce when in the air/when grappling

[wheat forum]

okay i did see such an thing is it smart to transfer the code so it uses that just in general?

[verbal dome]

You can achieve the same things with AddForce and modifying velocity. All AddForce does after all is modify the velocity

[wheat forum]

i am assuming to do that i just change for example for moving rb.linearVelocity = new Vector2(moveInput * moveSpeed, rb.linearVelocity.y); to like rb.AddForce(moveInput * moveSpeed, 0, 0)

[verbal dome]

What I like to do is something like cs var targetVelocity = moveInput * moveSpeed; var velocityDifference = targetVelocity - rb.linearVelocity; rb.AddForce(velocityDifference * snappiness);
So basically add the "difference to desired velocity" as a force. This way you won't overshoot.
snappiness is just a float that controls the acceleration/deceleration speed (and you could have different values for this based on if you are on ground, in the air, grappling, etc).

But the common, simpler way is to just use AddForce like you just showed and have some drag (linearDamping) on the RB to limit its speed

[wheat forum]

Okay ill just try the simpler way for now and if i have time for the other way ill try and implement that

but real quick back on to the grapple basically what id want to do is:
OnMouseDown > Raycast > If collides with LayerMask > Enable Joint + Line with anchor on mouse position

[verbal dome]

That sounds reasonable, is there an issue?

[wheat forum]

no just a side question to it doesnt really matter if it does or not but does that mean that it will only connect to the sides of a sprite?

[verbal dome]

Not 100% sure I understand but the raycast doesn't care about sprites, it cares about collider components

[wheat forum]

so if it collides with a BoxCollider so to say it will put the Anchor on the sides of said BoxCollider instead of the centre so to say

[verbal dome]

Oh, you'd set the anchor to the exact hit point that you get from RaycastHit2D.point

RaycastHit2D is what the raycast returns to you

[wheat forum]

Awesomeee!!

[slow blaze]

Why am I getting this even though the class I'm instantiating is not a monoBehaviour

You are trying to create a MonoBehaviour using the 'new' keyword.  This is not allowed.  MonoBehaviours can only be added using AddComponent(). Alternatively, your script can inherit from ScriptableObject or no base class at all
UnityEngine.MonoBehaviour:.ctor ()
MyEvent:.ctor ()```
```C#
public class MyEvent
{       
    public event Action StartDialogue;
    public event Action EndDialogue;

    public void doStartDialogue()
    {
        StartDialogue?.Invoke();
    }

    public void doEndDialogue()
    {
        EndDialogue?.Invoke();
    }
}```
```C#
public class DialogueEventHandler : MonoBehaviour
{
    public MyEvent dialogueEvent;
    public int test = 0;
    void Start()
    {
        dialogueEvent = new MyEvent();
    }

    // Update is called once per frame
    void Update()
    {
        if(test > 10)
        {
            dialogueEvent.doStartDialogue();
        }
    }
}```

[sour fulcrum]

have you saved all your scripts? otherwise you might have another script in the project with a MyEvent class that is inheriting from monobehaviour?

[slow blaze]

yeah I have saved and recompiled scripts multiple times

there's nothing really that has MyEvent the project is small and trackable

I'll try changing the class name to see what happens

[fickle plume]

Right click on the class name and go to definition

[slow blaze]

it goes to the class I sent, with no MonoBehaviour inheritance

changing the class name for some reason made it work

[fickle plume]

Make sure there are no other errors and build recompiled.

Also make sure you are not trying to use constructor in any MonoBehaviour object

[wheat forum]

I think i messed up with AddForce

[polar acorn]

Yes, probably. How about you look at the documentation for the function to see what parameters it takes and use the correct ones?
https://docs.unity3d.com/ScriptReference/Rigidbody2D.AddForce.html

[wheat forum]

So it needs to come from an Vector?

you cant just put a float or interger number

thats what i am understanding from that

[sour fulcrum]

yes

a single float wouldn't make sense

[verbal dome]

Well, https://docs.unity3d.com/ScriptReference/Rigidbody2D.AddForceX.html exists

And AddForceY ofc

[wheat forum]

that helped a lot already

The errors are gone at least the jumping tho isnt functioning but thats probably tweaking some numbers

[mint imp]

Hey guys im wondering what might be a better way to code variable planets/levels.
I have randomized planet levels you can pick at will in a hubworld map.
They have different types such as farm planet or jungle planet, which changes alot per planet.
When selecting a planet would it make more sense to make every planet type its own scene or have a single "planet scene" that i can dynamically adjust to fit the planet type you selected

[frosty hound]

If they're randomized, you can't have one for every planet of course. So it seems like a single planet scene you generate the planet in, is the right way to go.

How can I prevent my player clipping in/out objects it walks into? Here's the code being called in update

            transform.forward * CurrentMovementInput.y;

            if (moveDirection.magnitude > 1f)
                moveDirection.Normalize();

            PlayerRB.AddForce(transform.position += MoveSpeed * Time.deltaTime * moveDirection);

[naive pawn]

don't modify the transform

[rich adder]

how are we supposed to know anything if all we see is this image and none of the code or setup..
also did you check the console window for errors/warning

[naive pawn]

that's also not how addforce works

it doesnt have errors, all i have so far for the script is:

my one classmate did the same one and his works so idk what i did diff

[rich adder]

put some logs and see what is running and wat isn't along with logging their values

also wth kinda theme is that for VS 🤔

that feels unconfigured rather than a theme thing

its weird cause it does say Assembly C# instead of misc.. so its weird

ill try out ty

[rich adder]

yeah but normally the Monobehaviour should be Green and Distance method should be yellow etc.

[turbid jolt]

oh i see not sure im ngl

[polar acorn]

#💻┃code-beginner message

[naive pawn]

shouldn't monobehaviour be white in vs?

[rich adder]

wait what

[rich adder]

Transform is also white and should be green

I remember though VS has a weird theme too that also did some weird shit like this while still being configured.
OP needs to confirm by seeing if intellisense / suggestions still appear

[naive pawn]

huh i remembered types being white in some contexts

couldve confused it with the namespaces there ig

[elder hearth]

I did not mean to add a += there lol

[naive pawn]

so what's the actual code?

[elder hearth]

After my fix it is PlayerRB.MovePosition(PlayerRB.position + MoveSpeed * Time.deltaTime * moveDirection);

(I realised that i did not mean PlayerRB.AddForce lol)

[rich adder]

this will make rigidbody phase through objects, MovePosition is meant to be used with Kinematics

[naive pawn]

don't retype code man

[rich adder]

if you don't want it to do that you'd have to manually check collisions and prevent movement in that dir, otherwise use Velocity / AddForce

[naive pawn]

(commenting on the original message, to be clear)

you essentially ask us to check for issues in new code that is loosely based on what you have, instead of what you actually are using

[elder hearth]

Okay, my bad

[naive pawn]

(same for errors, just fyi)

[elder hearth]

It's not phasing through objects just jittering, but how would I use AddForce in this way? Just add ForceMode.Acceleration?

Wait actually let me just test it real quick

[rich adder]

jitter probably because you have a dynamic rb with Moveposition

im guessing at times it tries to compensate

[elder hearth]

Yep it works! still some jittering when trying to move into objects though( A LOT less tho). How can I fix this? Or is it one of those things where there isn't a straight forward fix?

[rich adder]

can you show a vid of issue

hard to tell cause many reasons it can jitter

[elder hearth]

Yeah sure! One sec!

[rich adder]

I see. Also I'd try calling the movement in FixedUpdate. See if that helps a little

Dynamic based rigidbody character controllers are a pain in the ass to get correctly working tbh

[naive pawn]

could you show your current movement code? i got kinda lost and i feel like i don't have the full picture there

[elder hearth]

I put it in FixedUpdate I got launched off the map lol

[elder hearth]

I put it back in update and I still do

odd

[rich adder]

with addforce you should not add onto your own position and fixed/delta time

[elder hearth]

Why? It was working fine a second ago.

[rich adder]

PlayerRB.AddForce( MoveSpeed * moveDirection, ForceMode.Acceleration);

instead of
PlayerRB.AddForce(PlayerRB.position + MoveSpeed * Time.deltaTime * moveDirection, ForceMode.Acceleration);

[elder hearth]

Well now I don't get launched off the map

[verbal dome]

Doing it in update will make it depend on the frame rate. More frames = more addforce calls

[elder hearth]

But now I slide around everywhere, maybe ForceMode.Acceleration is not a good idea

[verbal dome]

FixedUpdate runs at a fixed rate, so that would remove that issue

[elder hearth]

Hmm ok

thanks

[verbal dome]

(It's ok to do an impulse force like the jump in update, though)

[elder hearth]

So how can I stop myself from sliding around?

[verbal dome]

Easiest fix is linear damping on the rigidbody and/or friction on the physics materials

[elder hearth]

Okay thanks!

[junior basin]

Hey there, I'm getting a MissingReferenceException the moment I start the game, but everything is working completely fine. I've got this Lighter script attached to a lighter gameobject which is currently a child of the player

[wintry quarry]

Start by selecting that error and reading the full stack trace at the bottom of the console window

It will tell you which code is causing the error

[polar acorn]

Something is referring to a Lighter that has been destroyed

[limpid sparrow]

I have a question about the rotation, it behaves odd, i think. What do i need to do to rotate the child object, like the parent object - in the 2D space

[keen dew]

Not a code question but it behaves like that because the parent object's scale is not uniform

[polar acorn]

Rotating a child object with a parent whose scale is not uniform isn't going to do what you expect it to do

Every object's transform is relative to its parent, since the parent is 6 times wider on one axis, so will its children

That scaling remains in the same place no matter what orientation the child object is

[limpid sparrow]

Where do i have to ask this typ of question next time?

[polar acorn]

So, it skews

#💻┃unity-talk probably

[frail hawk]

What ya trying to achieve?

[limpid sparrow]

to rotate it around itself and then do the same thing for the childobject. A bit like a arm

to build something like this

void Update()
{
if (Input.GetKeyDown(KeyCode.DownArrow)) // forward
{
transform.Rotate(Vector3.forward * 45);
}
} Can someone explain to me why, this only works ones. i would like to stack it, like 45,90,135,180 and so on

[sour fulcrum]

Vector3.forward is global, kinda like how "North" points to the same place everywhere in the world

transform.forward is the specific to that object

[verbal dome]

Rotate works in local space by default so that should be ok here

[verbal dome]

Nothing wrong in this code snippet, something else is causing it to not work somehow

Are you clamping or otherwise modifying the rotation anywhere? Or does it have other scripts/components that could modify the transform?

I'd expect that code to rotate it along its own Z axis, 45 degrees per key press

Additively

[mint imp]

Randomized between a set amount of planets i want to make
Farm planet, forest planet city planet.

I would be changing the model of the planet and a few other factor like what enemies i have spawning. its not procedural tho

Surely still having a scene for every planet would suck because how would they all sync with other changes prefabs seem unreliable

[frosty hound]

If each planet is hand crafted, I would create separate scenes. The syncing thing is a non-issue if you're using prefabs? Unless you can think of a specific situation?

[earnest raven]

Hi! New to using IEnumerator. I'm trying to make walls lower and raise:

private IEnumerator RaiseWalls()
    {
        var t = 0f;
        t += Time.deltaTime;
        float percentComplete = t / 1f;

        arenaWalls.transform.position = Vector3.Lerp(wallEndPosition, wallEndPosition, percentComplete);
    }
    private IEnumerator LowerWalls()
    {
        var t = 0f;
        t += Time.deltaTime;
        float percentComplete = t / 1f;

        arenaWalls.transform.position = Vector3.Lerp(wallEndPosition, wallStartPosition, percentComplete);
    }

but I get this error:

Assets\Scripts\Enemy\SpawnTrigger.cs(60,25): error CS0161: 'SpawnTrigger.LowerWalls()': not all code paths return a value

I'm not really trying to return any value

[mint imp]

i jusy mean if i add a new feature to a scene i would have to go and add it to every other scene?
That seems like alot

[frosty hound]

What would be an example of a feature?

The proper way to handle shared things is to have a root/side loaded scene that contains it, so it exists when you need it.

For example, in the game we're doing, we have a bunch of levels - each are their own scene. However, of course we need to have the same UI/pause menu/gameplay elements between them so we have a LevelElements scene that gets loaded alongside any level.

When you leave the level , say to go back to the main menu, both the level and this LevelElements scene is removed.

[frosty hound]

All coroutines need to have a yield, somewhere.

Even if it's just yield return null, though if that's the case, then you're not using a coroutine correctly.

Also just reading your code, you're not using it correctly 🙃

[earnest raven]

well yeah no crap man I said I'm new to using it. I'm using it wrong, that's why I came here

[frosty hound]

Relax

[earnest raven]

such attitude some people may have

[frosty hound]

Oh okay, nevermind then.

I'll just do the short version of my answer: you need to loop inside your coroutine to do the progression.

[wheat forum]

Hi everyone i took a break saved and closed my unity normally i open it and come back to this

[polar acorn]

Do you want an answer or not

Because you got one and apparently decided it was a personal attack

If you can't be told that your code is incorrect, don't ask how to correct it

[frosty hound]

Check your package manager and see if TMPro is installed or if there's an update.

Actually, that's referring to the UnityEngine.UI ... it's missing 🤔

Check if that is installed in your package manager?

[wheat forum]

should it be in between there?

[frosty hound]

The Unity Registry option on the left

[wheat forum]

I am assuming most of these should be installed huh

yeaaa okay

[frosty hound]

Well, check the Unity UI one first, that's the one it's actually complaining about.

2D Sprites, sure, if you're intending to use them.

[wheat forum]

yea the thing is all of em arent installed not even unity physics and indeed uGUI

thank you ill figure out if ill just restart with a new project or figure out everything thats missing

[mint imp]

i never wouldve thought of that, no i have everything in 1 scene.
if i changed something about my player hud for example id have to change it in every scene

[grand snow]

Prefabs?

[frosty hound]

Currently, if you have it in every scene you would if they're weren't using the prefab.

But a prefab solves that issue. Modify the prefab and it applies to every instance of it.

I'd say 6.3 LTS (skiing game or not)

6.4 breaks a bunch of previous things so wouldnt recommend for beginners right now

Long term support, basically the supported/recommended version

OK, but I'm guessing apple does not have a collider on it. "Collectible_apple" does

yea

i added the script to Collectible_Apple and removed from apple and that fixed it

I'm modding a game with some particle systems in it, and I'm trying to modify the velocity over lifetime and it's weirdly inconsistent

For one set of particles it only applies the velocity if I set it to a constant value, for another it only works if I set it to two constants (with the same lower and upper bound so it should function the same as a constant)

What could be different? I can't seem to find anything that explains why they'd act differently.

(By doesn't work I just mean it doesn't seem to apply any velocity)

[naive pawn]

we can't really help with modding here, sorry #📖┃code-of-conduct

both because of legal issues, and also because modding imposes certain arbitrary constraints that we wouldn't know about (and wouldn't know how to work around)

[errant breach]

Hello everyone !
So i have an issue with my AI not rotating nor walking correctly.

I've freezed all X Y Z rotation in the rigidBody. I want to ai to spin 180 degrees when touching a wall.

• When i remove the freeze in Y, the AI stop walking / start shaking
• When i put a random owner.transform.Rotate(0, -36, 0); in the code, even with Y freezed, it work
• The rotate() function is called, but does not work...

if someone can check at my code and explain me why the rotation doesnt work, i would be extremly thankful !
https://pastebin.com/SE54fnKV

Here's with Freeze rotation Y disabled

[naive pawn]

you wouldn't want to modify the transform if you have a rigidbody, rotate via the rigidbody (and unlock Y rotation)

    //if (owner.transform.rotation.eulerAngles.y < -360) owner.transform.Rotate(0, 0, 0);
    //if (owner.transform.rotation.eulerAngles.y > 360) owner.transform.Rotate(0, 0, 0);

you don't need this part at all btw

you should not be reading eulerAngles to drive these decisions, they won't necessarily be consistent

eulerAngles should generally be write-only

[errant breach]

Oh, that's why... Alright, now the biggest issue is that when the Y rotation is unfreezed, the AI just doesnt want to move 😅

But thanks for the explanations !

[sharp bloom]

Is it possible to force classes to implement Unity event method such as Update() and OnDisable() using an interface?

Like if I just make a simple interface with public void OnDisable(), will that work?

[naive pawn]

unity messages aren't particularly special outside of unity knowing about them

[sharp bloom]

I kind of thought that, but I was also prepared to hear something like "they're super magic special messages that dont work like this"

[elder hearth]

Is there a way to not use friction and/or linear damping? These aren't working for my use case.

[sharp bloom]

Come to think of it, how does Unity know about the very existence of those methods at all? I mean the MonoBehavior class doesn't force a class derived from it to implement those.

Some kind of reflection magic?

[naive pawn]

it has "Update" hardcoded in the engine

[naive pawn]

messages are called via reflection, yes

[naive pawn]

you could make an opposing force that acts exactly like damping/friction, aka recreating those thigns

[elder hearth]

Ahh it is all magic to me

[naive pawn]

you have to use "opposing force to slow me down" in some capacity if you want it to slow down on its own. rather than recreate it, why not investigate why it isn't working for you?

[naive pawn]

for future reference, for stuff like "can i do X" within the language just try, tbh

[elder hearth]

The friction and linear damping are slowing my fall down, i mitigated this by checking when the object is in the air then making the dampening 0. But it still slides or feels floaty even when high

the damping and friction to be clear

[naive pawn]

linear damping would, friction would not unless you were also touching a wall (which you can configure to not give friction)

[elder hearth]

And how can I do that?

[naive pawn]

which part?

[verbal dome]

You can always just modify the velocity directly for maximum control.
Lots of people underestimate how tricky it is to make a movement controller that feels good though. Not beginner suff IMO

[naive pawn]

making the wall frictionless? that would be done with a physicsmaterial on the wall

[elder hearth]

friction would not unless you were also touching a wall (which you can configure to not give friction)

hmm okay

[naive pawn]

anyways if "friction" is making your character not handle well while you're in the air and not touching anything, it's not the friction.

[elder hearth]

wait true

[elder hearth]

this would be RigidBody.linearVelocity right?

It is, and honestly it works really well

I am quite happy with the results

[limpid sparrow]

I have a question about rotation, may some of you might be able to help. I want to rot a object, by pressing a key, so far it work's. The thing that i don't understand is, i print out the rotation. The print out is 0,45,90,135,...315,0. In the Inspector is the rotation, goes from 135 to -180, why? The Code is ' if (_middelObject)
{
transform.Rotate(Vector3.forward * 45); // and Vector3.back -> for the other direction
_selectionManager.middelRotation = (int)transform.rotation.eulerAngles.z; //This is the "printout"
}' H

[naive pawn]

that's how angle normalization goes sometimes

[rich adder]

unity goes -180 to 180 to keep the value small in the inspector

[naive pawn]

generally, don't read eulerAngles, treat them as writeonly

[limpid sparrow]

understood, and now how to get the correct value in the selectionManager _selectionManager.middelRotation = (int)transform.rotation.eulerAngles.z; ?

[rich adder]

what do you mean "correct value"
They're both correct, unity just normalizes it in the inspector

its the same value, just displayed differently

if you want to display it as unity does in inspector you just do the normalization yourself

float z = transform.eulerAngles.z;
if (z > 180f)
    z -= 360f;```

[limpid sparrow]

i'm using a if statement later and the statement don't work

[rich adder]

thats an entire different issue than what you're asking

[limpid sparrow]

something like if middleRoation is 270 do XY

[rich adder]

ok so what code do you have now and whats isn't working about it

[limpid sparrow]

switch ((middle, right, left))
{
case (0, 90, 270):
letterIndex = 1;
Debug.Log("Case 1");
break;

        case (180, 90, 270):
            letterIndex = 1;
            Debug.Log("Case 2");
            break;

something like this

[polar acorn]

What if statement and what is "doesn't work"?

[limpid sparrow]

i meant a switch statement

case 1 work, case 2 doen't

[verbal dome]

Maybe just store the rotation in an integer (0,1,2,3) or enum instead of looking for exact floating point number match

[limpid sparrow]

I try the normalising option, or that idea seems more pratical

Thank's

[rich adder]

@limpid sparrow how many chases do you expect ? it may be cleaner to use a lookup table

[verbal dome]

Theres also a one-liner way of doing this z = Mathf.DeltaAngle(0, z)
Wraps it to the -180..180 range
Though it might be confusing for some

[rich adder]

oh nice.. TIL

[limpid sparrow]

one for each letter of the alphabet

[rich adder]

giant switch

maybe a dictionary ?

[limpid sparrow]

i know

with 3 keys and 1 value? that's possible?

[rich adder]

of course

just dont use float

[limpid sparrow]

i will google it, thanks

[rich adder]

I'd probably round the float instead of truncate though

do you really want 9.9 to be 9 instead of 10 ?

[limpid sparrow]

i didn't use float, i'm using int's for. The Rotation doesn't need a decimal point

[rich adder]

I understand but you're doing (int) myfloat this will "truncate" the decimal

so I said in the example 9.9 would become 9 but you might want it to be 10 so its best to do a
int myInt = Mathf.RoundToInt(myfloat)

[limpid sparrow]

understood, i know what you mean now

[ruby python]

Hi all, I'm having a bit of a brainfart and hope someone can help out a little.

I have this code as part of my character controller (using addforce to control everything).

 private void MovePlayer()
 {
     // Let's try this shit
     Vector3 moveDirection = transform.TransformDirection(smoothInput).normalized;

     if (targetForward == 0 && targetRight == 0 && playerRigidBody.linearVelocity.magnitude > 0)
     {
         playerRigidBody.AddForce(-moveDirection * playerMoveSpeed, ForceMode.Acceleration);
     }
     else
     {
         playerRigidBody.AddForce(moveDirection * playerMoveSpeed, ForceMode.Acceleration);
     }
 }

Everything works great, except the stopping. lol. As you can see I'm trying to apply an 'Opposite' force to bring my character to a stop (increasing the drag doesn't really work unfortunately, kinda makes the character behave as though it's in clay).

Using the code above the force applied to the character does change direction correctly, however the character kinda flies off the screen.

Not entirely sure what I'm doing wrong, but there's obviously something wrong in my logic. (targetForward & targetRight are set between 0 and 1 with the WASD keys).

Could someone point me in the correct direction please? 🙂

[wintry quarry]

This isn't enough code.

But I don't see anything in this code adding an "opposite" force to slow anyone down

playerRigidBody.AddForce(-moveDirection * playerMoveSpeed, ForceMode.Acceleration);```
This is adding a force opposite your *input direction* not opposite the current direction of motion

and if the input is 0, it's doing nothing, because -0 is still 0

It's also unclear what targetRight and targetForward are or where they're being populated

[ruby python]

Oh yeah. eesh. Sorry, long day. Gimme a sec.

This is the complete script. There's a lot going on so it's a bit long, sorry 😕

[stark helm]

Guys should I do health regeneration in Update() or FixedUpdate()?
Could someone tell me which one works the best?

[rich adder]

do you want it every frame or physics step?

[solar hill]

or maybe per some arbitrary amount of time?

[naive pawn]

even with this route, you'd have to choose whether to update it on frames or physics ticks

[solar hill]

yeah youre right actually i missunderstood what nav said

he was just comparing the 2 updates lol

[unkempt kettle]

hey guys, I'm very inexperienced with tilemaps, is there a way I can make a script/shader that makes tiles gradually darker the further away they are from an "edge" of the tile (visual mockup in photoshop)

What I had initially on my mind is setting a script that can check my Tilemap/Tilemap Renderer components and assign a value of "Depth" to each tile (edge tile = 0, and every tile away from an edge is +1), and then depending on their depth, change their color multiplier to different shades of black

Is this something that can be done with tilemaps? Or will it be best to spend my time just making the extra few sprites of darkened terrain?

[stark helm]

I used normal update, so I will just leave it like that

[rich adder]

if its increasing across frames make sure to * Time.deltaTime otherwise different framerates will affect the speed (eg high fps = increases faster)

[naive pawn]

also if you're doing it in discrete steps, have an time accumulator and use loops to make sure it stays consistent over time

[elder hearth]

Just checking but Rigidbody.linearVelocity is world space and not local right? And if so how can I get the local space velocity?

[solar hill]

you can use transform.InverseTransformDirection

[elder hearth]

For what?

[solar hill]

to convert it from world space to local

[elder hearth]

PlayerRB.transform.InverseTransformDirection(PlayerRB.linearVelocity).x like this?

[solar hill]

Vector3 worldVelocity = rb.linearVelocity;
Vector3 localVelocity = transform.InverseTransformDirection(worldVelocity);

[elder hearth]

Okay so mine is just shorter?

[solar hill]

yes if you just need the lateral velocity use .x

[elder hearth]

Hmm okay

thanks!

[solar hill]

also you dont need .transform

[elder hearth]

Ohh okay thanks

[elfin pike]

looked in code general and couldnt find any thred with AI vision or detection system.

[solar hill]

huh?

[elder hearth]

Wouldn't this be #1202574086115557446 or #🤖┃ai-navigation

[solar hill]

also just make a thread yourself?

thats the point of the channel lol

[elder hearth]

fr lol

[sour fulcrum]

really depends on what ai vision / detection means

[solar hill]

im assuming just pathfinding with player detection

[elfin pike]

single cast ray wont work. then it will be same as in half life 2. 1 small item can block vision

[naive pawn]

could cast to multiple points

[solar hill]

i dont think thats how half life 2 handles player detection?

half life 2 has pretty advanced ai for its time

[elfin pike]

idk, i was looking in google and found guy talking how holding single can make them invisible

[sour fulcrum]

this isn't really an answer to what i said

you'd have to give proper context to what your looking for here otherwise people will just kinda vaguely guess what it is which might not allign with what you want

[elfin pike]

player detection for enemy. what else to add?

[solar hill]

this is more #🤖┃ai-navigation than anything then

[elfin pike]

i could cast 5 rays (4 for edges and 1 in center)

[solar hill]

or make a thread in #1390346827005431951

[sour fulcrum]

that sounds like a good start

I think some games have like points per limb?

[solar hill]

i was going to say

you could get away with 2 maybe

[elfin pike]

its very inactive about AI topics, because ai-navigation exists

[solar hill]

one from the center mass and one from the head

[sour fulcrum]

like if its a rigged enemy you'd get the center of each leg, the body, the head etc.

[solar hill]

right... then you use #🤖┃ai-navigation lol

[solar hill]

might be overkill for every single limb though

[sour fulcrum]

might be! that's why proper context on the question is important 😄

[elfin pike]

but thenn enemy wont shoot, if players half body is exposed or feet are sticking out belove table

[elfin pike]

how you would phrase it?

[sour fulcrum]

it's less about phrasing and more about giving people the information you already have

[naive pawn]

at some point would a vision cone be more reasonable if you want the smallest part peeking to count as a detection

[sour fulcrum]

think about all the questions we have asked you and all the respones youve posted,
in theory you probably could have gotten to this point in the conversation from 1 initial message that contained the thoughts and concerns you've already mentioned

its not like a big deal but it helps you get your answer faster and us understand it faster

[elfin pike]

it would be logical solution, but then how to acomplish it?

[solar hill]

well it depends, do you want to punish your players if their feet are slightly visible?

this is as much of a design decision as it is a technical one

most detection systems give the player a lot of lee way

because it just feels less punishing

[elfin pike]

doing shooter game (CQB). it should punish for player exposing.

[solar hill]

thats not what i asked though

[naive pawn]

or if yknow, a sleeve peeks behind a wall because of it being impossible to judge or control that within a game where input fidelty and depth perception are limited

[solar hill]

thats why games purposefully make detection for enemies "worse"

theres a difference between the player standing out in the open vs a small part of them peeking through cover

you dont want to punish the player for the latter

or you shouldnt, do whatever you want

[elfin pike]

Casting to limbs should be the best solution, i guess. doesnt pusinh player too much, but also doesnt ignore big parts exposing.

[solar hill]

imo you should cast from enemy limbs to your players center mass... and maybe the head

casting to individual player limbs is exactly what you want to avoid

[elfin pike]

i intend to add small points of last player seen position, it wouldnt allow player to repeak angle same way

[solar hill]

thats already something else

but a smart decision

[elfin pike]

max ray cast would be 6. (2 legs, 2 arms, head and torso)

[solar hill]

its your game, but this is exactly what we are telling you to avoid... casting too individual legs and arms could be too punishing, feel free to test it and play around with it

[naive pawn]

seems like a #1062393052863414313 question?

[tacit hound]

posted there

[elfin pike]

best question would be how much ray would be too much. Ray are expensive?

[sour fulcrum]

rays are cheap

[solar hill]

my grenade system uses up to 40+ rays for occlusion

theres also close to a hundred raycasts in certain update functions

no performance impact, so go crazy

[sour fulcrum]

it's using the fancy raycastcommand stuff but this dispersing prop step in my world gen does a millie raycasts lol

raycasts cheap cheap

[elfin pike]

then my crazy idea can work

[sick cliff]

Can someone explain what's wrong with my code?

[sick cliff]

ah thanks

[sour fulcrum]

if you read the full desc you can probably figure out how to use that value https://docs.unity3d.com/6000.4/Documentation/ScriptReference/Input.GetAxis.html

[naive pawn]

you probably want to GetButton instead, no?

an axis is an analog input

(the logic is kinda questionable though)

[sick cliff]

what is the diffrence?

[naive pawn]

it's treated as a button when you call GetButton

GetButton is for buttons while GetAxis is for axes

[sick cliff]

So i should use GetButton?

[naive pawn]

if your Fire1 input is a discrete button rather than an analog axis, yes

does it work?

I'm sorry, it was a different code.

Im trying to make a turn based strategy game and want to use hexes for the (3d) map. My problem is that the Asset that im using has a wrong center and I dont know how to allign the hexes. (I dont know the Dimensions either). Should I make my own basic asset, use rectangels, do it in 2 d or use an other asset? Thank you.

[verbal dome]

What asset?

Unity has a grid component that supports hexagons

[oak cloud]

Its a Hexagon

[verbal dome]

A texture?

You can see its dimensions in unity if you select the texture, or in your OS file browser

Oh 3D mesh?

[oak cloud]

its a prefab

my idea was to make a grid of game objects and teleport the Pieces to the center of the game objects

[verbal dome]

Are you using the grid component, if not, you probably should
https://docs.unity3d.com/6000.4/Documentation/ScriptReference/Grid.html

For example GetCellCenterWorld would be useful for placing objects on the cells

[oak cloud]

Im not using it reading about it now thnx

[high needle]

Hello. Are there any Codewars users here? I'd love to add some allies

[elder hearth]

When compiling my game or using playmode my variable change( well this is my hypothesis). My code is this:

            Vector3 worldVelocity = PlayerRB.linearVelocity;
            Vector3 localVelocity = this.gameObject.transform.InverseTransformDirection(worldVelocity);

            // Movement direction (camera-relative)
            Vector3 moveDirection =
                (this.gameObject.transform.right * CurrentMovementInput.x +
                this.gameObject.transform.forward * CurrentMovementInput.y) * MoveSpeed;

            if (moveDirection.magnitude > 1f)
                moveDirection.Normalize();

            // Jump
            if (groundedCheck.isGrounded && JumpIsPressed)
            {
                JumpIsPressed = false;
                PlayerRB.AddForce(Vector3.up * 391.65f, ForceMode.Impulse); // simplified + tunable
            }

            // Target velocity
            Vector3 targetVelocity = moveDirection * maxSpeed;

            // Convert target velocity to local space for comparison
            Vector3 targetLocalVelocity = this.gameObject.transform.InverseTransformDirection(targetVelocity);

            // Calculate velocity difference
            Vector3 velocityChange = new Vector3(
                targetLocalVelocity.x - localVelocity.x,
                0,
                targetLocalVelocity.z - localVelocity.z
            );

            // Apply movement force
            PlayerRB.AddForce(this.gameObject.transform.TransformDirection(velocityChange), ForceMode.VelocityChange);

            // Friction / stopping
            if (CurrentMovementInput == Vector2.zero && groundedCheck.isGrounded)
            {
                Vector3 horizontalVelocity = new Vector3(worldVelocity.x, 0, worldVelocity.z);
                PlayerRB.AddForce(-horizontalVelocity * 0.1f, ForceMode.VelocityChange);
            }
``` IT works fine in the editor, unity 6.4 and this is all called in update.

[sour fulcrum]

what variables

and what do you mean it works fine in editor

[elder hearth]

Wait actually I should just double check this rq

I'll be back in a sec

[sour fulcrum]

you don't need this or gameObject for most of this btw

you can just access transform directly

[elder hearth]

Oh I know I just use them because of habit

I don't even know when I began to do that lol

[grand snow]

js moment

[elder hearth]

Okay turns out this isn't variables changing. But my when I move in a compiled game it goes CRAZY. I am using FishNetworkin. I wonder if thats it.

Like my Velocity is the maxium possible value

[grand snow]

you should only add force in FixedUpdate

[sour fulcrum]

thats a question for wherever people talk about fish net

[elder hearth]

Yeah I was thinking that

I'll go to their server

[grand snow]

This is probably due to higher framerate in the build so it just adds even more force

[elder hearth]

but it is so dead lol

[elder hearth]

Hmmm okay

Wait I have a way to test this

[grand snow]

Add force/change velocity in Fixed update only

Its such a critical thing to learn

[elder hearth]

OMG IT IS, THANK YOU. I have actually been going crazy with this since yesterdayyyyyy. I cannot thank you enough

[elder hearth]

I can tell lmaooo

[elder hearth]

actually since the day before yesterday.

[grand snow]

You also somehow missed learning about delta time and how we can use this to make things "framerate independant"
https://docs.unity3d.com/6000.4/Documentation/ScriptReference/Time-deltaTime.html

How to alter physics and using delta time/frame time is a common topic for game development/realtime 3d applications

[elder hearth]

I learned it, but just incorrectly i guess

[lean sandal]

It's hard enough trying to learn code itself

but when you cant even use visual studio without it messing up it makes it even more stressful. I cant get it to so suggestions at all when im typing stuff. Im using 2026 and I updated it. Ive already got .net and stuff installed. I tried many different solutions and none worked...

Can someone please help me fix it I can screenshare if I need too

[sour fulcrum]

theres no screensharing here sorry

make sure you've gone through this if you haven't gone through it all

[lean sandal]

if i do something like public or public int it autofills it
but if im doing oncollisonenter or
getcomponent I dont get shit

I read through all of that stuff

[grand snow]

If the unity tools were installed it should suggest unity message names 🤔

but technically they work in a non standard way so they dont "appear" by normal c# rules (unity calls em by magic)

[elder hearth]

Hi! It is me again lol, but anyways. When I rotate an object, but it's rotates around a pivot, my method doesn't move the Object to the target's new position.

    void MoveTowardsTarget(Rigidbody Object, Transform target, float force)
    {
        Vector3 pendingForce;
        Vector3 direction = (target.position - Object.position);
        pendingForce = direction * force;
        Object.linearVelocity = pendingForce * Time.deltaTime;
    }

[elder hearth]

Do people actually install Visual Studio through Unity Hub?

[grand snow]

no cus its an old ass version

[elder hearth]

Fair lol

[cosmic dagger]

you can combine the pendingForce declaration with the assignment; no need to separate it. Object isn't the best name for a variable, because Unity has their own Object class, and it doesn't describe what the variable is: a Rigidbody. Lastly, you do not multiply velocity by deltaTime . . .

[keen acorn]

Quick question, what's MonoBehavior and why would we not want to have scripts derive from it?

[keen acorn]

lmao i had the 2019 version until just a few months ago

[cosmic dagger]

but we do (derive from it). A large portion of your scripts will indeed derive from MonoBehaviour because that's how you create components to attach to your GameObjects . . .

[grizzled steppe]

Any idea why raycasts are being so buggy? I am walking into the object it doesn't detect but if I jump onto it it detects fine...

some prior terms first:

• UnityEngine.Object is anything that the Unity engine can keep track of
• Component is anything that you can attach to a GameObject
• Behaviour is a Component that you can enable and disable
• MonoBehaviour is a Behaviour, and user scripts are allowed to inherit from this class

[cosmic dagger]

the real question is knowing when to derive from it or to use a plain 'ol c# class (POCO) . . .

[swift crag]

The name itself is a bit of a legacy thing – I believe it refers to the Mono runtime (the system that actually runs your C# code)

[keen acorn]

ah, i see

[swift crag]

You inherit from it to create new kinds of components

If you are not creating a kind of component, then you need to derive from something else (or nothing at all)

[grizzled steppe]

This is my helper class I use.

[swift crag]

e.g. ScriptableObject to create new kinds of generic Unity objects

[grand snow]

Understanding object oriented programming should explain it anyway

[sour fulcrum]

you gotta read this again 😄

and we'd need to see where your using the stuff in this helper class

[cosmic dagger]

mote the Mono in MonoBehaviour. it's intended use is for a single behavior . . .

[sour fulcrum]

that is not why it is called that lol

we're changing the game over here, okay . . .

[sour fulcrum]

im leaving monobehaviours behind entirely 😄

scriptableobject singletons and poco classes my beloved

[grand snow]

its a shit old name and nothing more

[grizzled steppe]

See it works fine for ground and stuff, but on wedged mesh parts it completely breaks

[solar hill]

mono means one
and behaviour means behaviour

[grand snow]

🤦

[solar hill]

its a simpsons reference 😔

[cosmic dagger]

facts. these are my ride-or-die . . .

[grizzled steppe]

See it only detects the hit if I am landing on it.

[teal viper]

Where's the damn StereoBehaviour??

[grizzled steppe]

But the first two left and right hits should also be factored and they arent for some odd reason

[cosmic dagger]

i wasn't sure on what to name the double behavior . . .

[swift crag]

CoreCLRBehaviour 😉

[swift crag]

i'm not sure what you mean by "first two left and right hits" -- are you takling about the boxcasts?

small thing: your boxcasts are inconsistent; the right leg doesn't add VectorDown

but that only matters while you're crouching

[grizzled steppe]

Yes

But even if the right doesn't hit the left one should be but doesn't detect it

It's skipping the wedge and hitting the ground under

The only time it actually detects the wedge is if I am jumping stright on top of it

[swift crag]

if a BoxCast starts inside of another collider, it will ignore that collider

That would explain why it works when you jump

[grizzled steppe]

So how would I solve this issue?

If a wedge can be higher than player

In terms of like map designing and such

Cause I want to have some walls that are angled

or like angled floors

[swift crag]

i'm guessing that the boxcasts are starting low enough that, when you walk directly into a sloped surface, they start inside of the surface

and thus don't detect it

raise them up a bit and see how it behaves

[grizzled steppe]

yeah and if I am walking onto one it skips it

plus theres an issue where I need to be able to crouch inside vents with slopes and i am using wedges as elevations

[cosmic dagger]

if you only need one or the first hit, then using an array of size 1 is unnecessary . . .

[grizzled steppe]

okay

Is there a way to make it so unity can detect objects if you start raycasting, since my object uses a custom collider?

Like here the green boxes are the debuggers for the boxcast. but they are outside of that wedge when they start so they should be hitting that wedge, instead they are going through it. and the player is only so big, so having to raycast high in the sky just to detect a wedge under the player sound a bit overkill, plus some elevations are drastically bigger than the player.

[elfin pike]

I was sent back from ai-navigation, but now I have question collider. Is there way to make truncated pyramid collider?

[naive pawn]

in 3d, correct?

well, mesh colliders can be any shape

[elfin pike]

Maybe it's possible to write class

Or shouldn't bother with that and do mesh collider

[naive pawn]

i don't think you can

[elfin pike]

To be fair sad that we are limited with square and sphear

[sour fulcrum]

(and meshes)

[naive pawn]

(and capsules)

[inland crystal]

More than once I wished I could have a cylinder collider tbf

Although, if by "truncated pyramid" you mean a frustum, you could do it manually using GeometryUtility

I have a List<Int2> that represents tile coordinates in relation to an object. I wish to rotate these by 90*; any easy way?

[grand snow]

Do you mean vector 2 int? But yes you can rotate vectors around 0,0,0 using Quaternions

[naive pawn]

if you want to get new structs that are rotated, then loop through and rotate them

for 90° it's just a swizzle and negate one of them

[grand snow]

Huh til that's a thing

[rocky wyvern]

yeah makes sense

[rocky wyvern]

didnt want to use quats because idk floating point and floortoint or smt seems inviting trouble

[naive pawn]

yeah quite a few primitive transforms can be done with a combination of negate and swizzle (eg reflect on X, reflect on Y, reflect on y=x, rotate 90°, rotate 180°)

[limpid sparrow]

Is there a mistake in my code ? "Clicked" get's print out twice public void LeftMouseClick(InputAction.CallbackContext context) { if (context.performed && clickable) { Debug.Log("clicked"); _renderer.material.color = Color.green; ClickFunction(); // the first line in this function is clickable = false } }

[frail hawk]

ClickFunction probably also has a Debug.Log("clicked")

[limpid sparrow]

Nop private void ClickFunction() { clickable = false; StartCoroutine(DeactivationTime()); } public IEnumerator DeactivationTime() { Debug.Log("Deactivation started"); clickable = false; for (int i = 0; i < 30; i++) { yield return new WaitForEndOfFrame(); } Deactivate(true); }

[teal viper]

The fact that "deactivation started" is only printed once, makes me think this is a different "clicked"..? Can you show the call stack of both?

[limpid sparrow]

If i'm understand that corret, the clickable get set to false and still get trigger again, that's got me puzzeled

found the mistake, the script was attached twice. My fault, upps

[frail hawk]

is there not somethign like context wasPerformedthisFrame for single click

[elder hearth]

This shows the problem better. The highlighted object is the grabber. The object being grabbed is not parented to the grabber or the player in anyway

The grabber rotates around a pviot, and I don't think that is updating the position

Yep it isn't being updated(the grabbers position)

[lament basin]

Would a message queue for the server processing interaction events on the terrain be overkill?

I'm thinking for things like chest updates and other interactions it would make sense for consistency

[fickle plume]

Move it to #1179447338188673034 , please

[elder hearth]

It is? For now I have just made so it teleports to grabbers position. And it works well except for the clipping(obviously)

[shy tapir]

Hello Guys

[mint imp]

Howdy everyone
I'm working on toollips for my ability selection menu.
Basically I have a square icon representing an ability you can use (just a button), when the mouse is over it i want a box to show up and show you the name and description.
I'm already using a detection system per button system to display a selection outline for each button, so I was thinking to just call the toolip to spawn with that?
How do people normally add toolips?

[limpid sparrow]

why is "color" not working - Cannot resolve symble"color". i already using a KI, doen't helped. There isn't a typo, right? the private Image is Internal class

[slender nymph]

using UnityEngine.UI; is grayed out which indicates that you are not using the Image type from that namespace

[wintry quarry]

Because tabImages is an array

you can't do .color on an array

[slender nymph]

also that

[wintry quarry]

you need a specific Image from the array, then you can do .color on it

Box's concern is also true - you probably made your own Image class

[limpid sparrow]

private UnityEngine.UI.Image tabImages; okay this works

[frail hawk]

yeah but you still should choose another name for your class

[slender nymph]

yeah either never name your types the same as a unity type, or make sure it's in a namespace so it forces you to fully qualify it or you get an ambiguous reference error

[frail hawk]

you can use a small ui image that you enable and disable when you hover ove rthe buttons

[swift crag]

importantly, tooltips need to:

• appear on top of most other UI elements
• not participate in automatic UI layout

assuming you're using UGUI, you'll want to put your tooltip prefab at the very bottom of the UI hierarchy and give it a Layout Element set to ignore layout

if this is UIToolkit, use an absolute-positioned element

[midnight tree]

I have a quick (weird) question about vectors.

Doesn't it bother you that the direction of movement (normalized) and a regular vector(with distance) are indistinguishable, and you have to specify, for example, in the summary that you want a normalized vector and not a regular vector as input to a method?

Or am I an idiot and it is possible to understand from the principle what exactly the method requires?

[naive pawn]

what differentiates a float that's an absolute value vs a float that's a delta?
or a float that's in time vs a float for a distance

don't rely on just the types to determine what the value represents

[swift crag]

You could, indeed, use the type system to distinguish these concepts

it would be very awkward, though, since many operations make sense for both "types"

[naive pawn]

the types show how the value can be encoded, but semantics (and documenting those semantics) are also important

[swift crag]

it's the same idea as using separate types for "sanitized" strings and "unsafe" strings

[wintry quarry]

This is why functions have (or should have) documentation and/or self-documenting names

e.g. it's why you call your parameter playerPosition or playerForwardDirection not playerVector

[swift crag]

i kind of wish it was just float3 instead of Vector3

(like it is in the Mathematics package)

that makes it clear that the type simply represents 3 floats

it doesn't hint at a particular meaning

(of course, in computer science, "Vector" has a meaning totally divorced from the mathematical idea of a "Vector")

[naive pawn]

that makes it clear that the type simply represents 3 floats
i mean it kinda doesn't, given that it has all the normalization/magnitude/dot/cross stuff

[naive pawn]

they aren't totally divorced, but the common semantic narrowing is different (and differs in context, not just cs vs math)

Vector2/Vector3 in unity are math vectors (whereas Vector† in java or vector in c++ would be the cs vector you're referring to)

[fading marten]

Anyone think they can help me? I'm trying to make it so that when my player finishes their jumping animation their capsule collider returns to the normal size it has before it jumps

I have this script that plays when a certain frame of the animation is hit and it returns to running, however I can't seem to access my players capsule collider there

[swift crag]

show us what you've done

if you have a component that responds to an animation event, then you can give it a CharacterController field and assign it in the inspector

[fading marten]

returnToRun is the function that is called when the animation hits the key

[swift crag]

what's stopping you from updating the character controller right now?

[fading marten]

I haven't used that before
