I'm skimming through the docs

OnSelectEntered(XRBaseInteractor)
OnSelectExited(XRBaseInteractor)
OnSelectCanceled(XRBaseInteractor)

are you sure?

[swift falcon]

wait

wow

thanks

[edgy lynx]

So then in this example, how are you supposed to make the event trigger for a specific object, rather than all? Imagine hundreds of enemies/objects with healthbars, and calling:

    private void OnEnable() => Health.onHealthChanged += UpdateHealthBarUI;
    private void OnDisable() => Health.onHealthChanged -= UpdateHealthBarUI;
    public void UpdateHealthBarUI() => _healthBarSlider.value--;

[clever spade]

ID them.

Then you could pass in a parameter specifying which should be affected

[edgy lynx]

Ok, yeah that's what i read in a forum post.

[leaden ice]

You would either:

• not use a static event (use a normal instance event)
• pass the source parameter in your delegate

e.g.

public delegate void HealthChangeHandler(HasHealth source, float newValue);```

Recommend using an instance event in this case though otherwise you have a lot of wasted no-op event handlers doing something like:

void OnHealthChanged(HasHealth source, float newValue) {
  if (!source == theSourceIAmInterestedIn) return;
}```

unless you're doing something like:

void OnHealthChanged(HasHealth source, float newValue) {
  healthBars[source].SetValue(newValue);
}```with a Dictionary and one central handler

[edgy lynx]

Alright, struggling to see this one through:

public class Health : MonoBehaviour
{
    public delegate void OnHealthChanged(Slider slider);
    public event OnHealthChanged onHealthChanged;
    private void OnCollisionEnter(Collision collision)
    {
        if (collision.gameObject.CompareTag("Bullet"))
            onHealthChanged?.Invoke(enemyHealth);
    }
}

And please don't mind the name of class or comparetag, etc it's all just a test project for learning. Nothing concrete...

So then I need a concrete reference though then in my UI class right?
Since it's not static now.

I just want it to do _sliderHealthBar.value--; each time there's a collision.

[leaden ice]

I don't see why the delegate would have a Slider parameter

Health script shouldn't care about UI stuff

It should have a float parameter right? For the new health total or something?

then in the UI script:

void UpdateHealthBarUI(float newHP) {
  mySlider.value = newHP / maxHP;
}```

(should probably use a filled image not slider though)

[edgy lynx]

Will review in a couple mins and respond.

[edgy lynx]

Yes, so I've updated, but then wouldn't my HealthBarUI script still require a direct reference to Health.cs otherwise, how would I call the onHealthChanged event?

[leaden ice]

Oh it does require a reference

that's why you have an error now

I was assuming you had a static event

since it's not a static event you need a direct reference to the object whose event you want to listen to

[edgy lynx]

so doesn't this defeat the purpose kinda in terms of separation?

And I'm asking that in a way of truly trying to understand.

Since when it's static, it's updating all health bars at once, so that wouldn't work.

[leaden ice]

Events are not a magic way to decouple things or remove the need to have things reference each other

the only thing events do is invert the referential direction

so instead of your Health script having a reference to the UI
now your UI scirpt has a reference to the Health script

[edgy lynx]

Yeah, that makes sense and helps view it a bit more properly. In the end, I suppose that connection always needs to exist in some form.

[leaden ice]

Yes indeed.

[edgy lynx]

& maybe that's where something like Interfaces come into play?

Rather than a concrete reference.

[elfin nova]

hello, someone knows if the rigidbody velocity, can make the object traspass other objects?

[leaden ice]

it sure can!

[leaden ice]

Here's an explanation:
https://gamedev.stackexchange.com/a/192403

[elfin nova]

and how i can make it to that dont succes? 😦

[swift falcon]

I don't know if this is the best channel but, I have this simple script:

Animator animator;
    void Start()
    {
        animator = GetComponent<Animator>();
    }

    public void Hover()
    {
        animator.Play("Hover");
    }

    public void Exit()
    {
        animator.Play("Exit");
    }```

and, hover and exit are being called by OnPointer Enter and Exit respectively. (event trigger)

I also have my animation states in the image. However, when Exit transitions into Idle, it sort of flashes the first frame of Exit for a split second, creating a really bad looking transition effect. How can I fix this?

[leaden ice]

• continuous collision detection
• slower objects
• thicker colliders
• higher physics tick rate

[elfin nova]

i change the velocity as less velocity and still not works.., for collision detection did you reafear to the component in the rigidbody?

[swift falcon]

nvm, im stupid, transition arrow > settings > transition duration = 0

[quasi terrace]

Hello! I was wondering if anyone could help me with this. In the Equipment class the Debug.Log I do in the setOutlineColor() functions returns a NullPointer even though the outline component is clearly initialized in the Start() method. The Start method is the ONLY time where I directly modify the outline variable so I was thinking that perhaps I was accessing the equipment array incorrectly. I've been stumped with this for a while now and would appreciate any ideas as to why it's turning out Null, I cut out bits that didn't relate to this specific problem.

public abstract class Equipment : MonoBehaviour {
    public EquipmentSlot equipSlot;

    private Outlinable outline;

    protected virtual void Start() {
        outline = UnitSelections.Instance.SetupOutline(gameObject);
        Debug.Log(outline.name + 1); //Completely fine
    }

    public void setOutlineColor(Color color) {
        Debug.Log(outline.name + 2); //NULL
    }
}

public class Sword : Equipment
{
    protected override void Start() {
        base.Start();
        equipSlot = EquipmentSlot.Sword;
    }
}

public class CharacterEquipmentManager : MonoBehaviour {
    private Equipment[] currentEquipment;

    void Start() {
        int numSlots = System.Enum.GetNames(typeof(EquipmentSlot)).Length;
        currentEquipment = new Equipment[numSlots]; //Make the equipment array have same number of slots as there are equipment types
    }

    public void setOutlineColor(Color color) {
        for (int i = 0; i < currentEquipment.Length; i++) {
            if (currentEquipment[i] != null) { //If there is something equipped in this slot
                currentEquipment[i].setOutlineColor(color);
            }
        }
    }
}

The sword is an example child class of equipment that I use in my scene. And variables like the equipmentSlot work perfectly fine and don't turn out null, it's just the Outlinable component for some reason. In the Editor, the outline component isn't null either.

[leaden ice]

just set the collision detection type in the inspector

[leaden ice]

setOutlineColor is probably running before Start is

Note that Start() runs quite late. If you Instantiated this thing, Start probably won't run until the next frame

Usually Awake() is the place to do initialization stuff

[quasi terrace]

I do setOutlineColor whenever I hover over the object, which can run 1000's of time. So it's definitely after Start() has happened.

[leaden ice]

stylistic note: In C# convention methods should use PascalCase, so setOutlineColor should be SetOutlineColor

[leaden ice]

Show the full stack trace of the error

[elfin nova]

yes i did but still passing the objects 😦

[leaden ice]

every time or only sometimes?

[elfin nova]

everytime

[leaden ice]

oh then it's probably something else

like you don't have a collider or something

or your collider is a trigger

show the inspectors of both objects

[elfin nova]

the projectile

the wall

[leaden ice]

how fast is your projectile going

also the wall should probably be Kinematic

rather than using freeze position

[elfin nova]

i tried but still not work xD

[quasi terrace]

Equipment.cs at line 21 being the part where I access the outline

[leaden ice]

how are you assigning the values in the currentEquipment array?

[elfin nova]

the LaunchVelocity is normally 2

[leaden ice]

can you try using a SphereCollider instead of MeshCollider for your projectile

just for testing

also are you certain the objects are actually colliding in 3 dimensions?

[quasi terrace]

    public void Equip(Equipment newItem) {
        Equipment oldItem = null;

        int slotIndex = (int)newItem.equipSlot; // Find out what slot the item fits in

        if (currentEquipment[slotIndex] != null) {
            //If you're trying to equip when there's something already there
            oldItem = currentEquipment[slotIndex];
        }

        if (onEquipmentChanged != null) {
            onEquipmentChanged.Invoke(newItem, oldItem); //Trigger callback when item has been equipped
        }

        currentEquipment[slotIndex] = newItem; //Add the item to the current equipment array

        AttachToMesh(newItem); //Attach the item to the character as a new child object
    }

In this way, the script works and attaches a prefab with Equipment script attached onto the gameobject.

[leaden ice]

and where does newItem come from here? Can you show the code that calls this?

my working theory is you're passing in the prefab here, rather than the newly created instance

[elfin nova]

well i'm using a OnCollisionEnter so i guess

[elfin nova]

let me try

[quasi terrace]

Simply:

public Sword sword;

Which corresponds to the picture

[leaden ice]

if you're using OnCollisionEnter then they are colliding and I don't know what you are worried about

[leaden ice]

wdym?

[quasi terrace]

The outlinable component is attached at runtime through the Start() script

[leaden ice]

I was asking for the ccode that calls this Equip function

[quasi terrace]

Sword is a child class of Equipment

[leaden ice]

right so... you're passing a prefab in?

directly

[quasi terrace]

    protected override void Interact() {
        hasInteracted = true;
        unitsInteracting[0].GetComponent<CharacterEquipmentManager>().Equip(sword);
        unitsInteracting[0].GetComponent<CharacterEquipmentManager>().Equip(shield);
        Destroy(gameObject);
    }

It kinds of goes on and on

[leaden ice]

not an instance of the prefab, but the prefab itself

that would be the problem

[quasi terrace]

ah

[leaden ice]

I would expect something like:

Equipment swordInstance = Instantiate(sword);
unitsInteracting[0].GetComponent<CharacterEquipmentManager>().Equip(swordInstance);```

[quasi terrace]

Here is my instantiation

    private void AttachToMesh(Equipment equipment) {
        if (equipment.equipSlot == EquipmentSlot.Sword) {
            Animator anim = GetComponent<Animator>();
            Instantiate(equipment.gameObject, anim.GetBoneTransform(HumanBodyBones.RightHand), false);
        }
        if (equipment.equipSlot == EquipmentSlot.Shield) {
            Animator anim = GetComponent<Animator>();
            Instantiate(equipment.gameObject, anim.GetBoneTransform(HumanBodyBones.LeftHand), false);
        }
    }

I do it in the attachmesh fxn, is it too late to call that?

[leaden ice]

don't do Instantiate(equipment.gameObject)

just do Instantiate(equipment)

your life will be so much easier

[quasi terrace]

Alright

[leaden ice]

anyway you can do this:

    private Equipment AttachToMesh(Equipment equipment) {
        if (equipment.equipSlot == EquipmentSlot.Sword) {
            Animator anim = GetComponent<Animator>();
            return Instantiate(equipment, anim.GetBoneTransform(HumanBodyBones.RightHand), false);
        }
        if (equipment.equipSlot == EquipmentSlot.Shield) {
            Animator anim = GetComponent<Animator>();
            return Instantiate(equipment, anim.GetBoneTransform(HumanBodyBones.LeftHand), false);
        }
    }```

that will now return the newly created instance

you'll still need to get that reference over to your Equip function somehow

Hard to tell how because I don't know the full structure here

[elfin nova]

i used and not changed

[leaden ice]

you said OnCollisionEnter was running right? So what's the issue? If that's running, the collision is happening

[elfin nova]

the problem is, the collision don't detect all collisions and idk why

[leaden ice]

I don't know what the means

can you show some video or screenshot to explain your issue better

[quasi terrace]

Thank you so much!! It works perfectly now. I guess that I had to add the INSTANTIATED version of the equipment into the array.

[leaden ice]

Yep, do you understand why?

[quasi terrace]

Yes! because the previous version was accessing the base prefab of the sword. But after I instantiated it, I added the outline component in Start(). I needed to access the NEW sword gameObject and I could do that by adding the instantiated sword into the equipment array 😄

[void basalt]

So I have a public array in one of my scripts. I want it to auto-initialize to 30 slots. However unity has it saved as 0 slots in the inspector for all objects. Really annoying.

Any way I can force push an update?

[leaden ice]

The most foolproof way would be to change the field name 🤣

[void basalt]

gross

lmao when I change it back to the last name, it goes back to 0 slots

[leaden ice]

I have a unit testing question:
I have a unit test where I'm comparing two Vector3 with Assert.AreEqual(vec1, vec2);
I know this uses .Equals under the hood which checks for exact floating point equality
In my case, approximate equality is acceptable
Is there any graceful way to write something like Assert.AreApproximatelyEqual(vec1, vec2, tolerance) ?
I know I could do Assert.LessOrEqual(tolerance, Vector3.Distance(vec1, vec2)) but the test failure output is so much less helpful that way.

[leaden ice]

yeah it's saved with that name in the scene/asset file!

Is there a reason you need to serialize the array?

[void basalt]

It just needs to be public. I can use HideInInspector after

[leaden ice]

Use [NonSerialized]

not HideInInspector

[void basalt]

oh perfect

[leaden ice]

HideInInspector won't fix it

[cosmic rain]

Don't make pubic fields. Make a property or a getter method for it.@void basalt

[leaden solstice]

Well..
https://github.com/cathei/RotationMath/blob/main/Assets/Tests/VectorAssert.cs

[leaden ice]

hmmm ok that kinda works 🤔

[leaden ice]

$#$#%#! 🤣

so close!

[leaden solstice]

Lol

[leaden ice]

Hmm I wonder if casting my floats to double or decimal, doing the math, then casting back would give me better precision

and if that's worth it 🤔

[edgy lynx]

fyi mate

@leaden ice - Record the information in a cloud-based database?

[leaden ice]

I didn't say it's a good idea

you asked though

by "the information" i just mean a flag like the aforementioned PlayerPrefs flag

i was hoping for a tag like:

Thank you, I cant believe i missed it. Works great now.

RuntimeInitializeOnLoad will run when the game starts, but you can't determine something like "is this the first time the game ran" without storing that information somewhere

Thanks - i was hoping there was - i guess ill have to store the info - thanks for the help

[spring fractal]

hi, i was just wondering if theres a simple way to spawn an object in a random position outside the bounds of the camera? Not rly sure what the best way to do that would be

[simple sable]

Hi.

I have situation where I'm trying to adjust the speed of a moving object that falls based on the distance it has to travel.
I know the distance, the minimum speed (0.9f) and I want to try to use 1.9f as maximum.

I just don't know how to do it. I think I need to use Mathf but not sure.

If anyone can help, that would be awesome.

[vague tundra]

The speed of the zoom when using scroll-wheel to navigate through my scene in Scene View is relative to your most recently focused object. I want the speed to be independent of focused objects. Any way to achieve this?

[somber nacelle]

just for clarification is the speed supposed to change as the object moves and the distance changes, or is it supposed to be a set speed based on the distance at the start? and also do you have a minimum distance needed to travel in order to reach maximum speed?

[ivory sky]

Hey guys I have a very strange problem. I'm trying to optimize my game using Static Batching, but it dosen't work as it should. I have over 100+ instances of RailEdge object and when I am launching the game (with static batching on) I have 471 batches. When I turned off batching I still have 471 batches. Could someone tell me what the frick is going on?

The amount of FPS is the same in both cases (I've just checked this)

[simple sable]

I just want to get a constant speed based on the distance at the start.

[somber nacelle]

and do you have a distance in mind that would be equivalent to the max speed?

[simple sable]

Well, the object can move between 180 and -180. I imagine if the object starts at 180 then it should have the fastest speed.

Right?

[somber nacelle]

my guy, how this is supposed to work is entirely up to you. i'm just asking clarifying questions so i can help point you in the right direction

is there a minimum distance that would equate to the maximum speed

[simple sable]

I see.

Well, maybe I should make it more clear. I have a system in place that let's you drag an object and drop it. Once it's dropped, it falls down. The object will always fall down to -180 in a 640x360 canvas. And it can be dropped from a maximum of 180.
What I need, as said before, is to make it so that if I drop the object from -160, the animation to be quicker than if I drop it from 150.

This is just an example, of course.

0.9f looks good, but only when dropped from a higher point. Having the object fall for 0.9f seconds when it's dropped from a lower point looks off.

[somber nacelle]

okay so then if dropping from 180 has to be faster than dropping from 179 and the maximum speed is 1.9, then you need to get the startingDistanceToTravel divide that by maximumDistanceToTravel, that will give you a percentage of the maximum speed you can go, then you have a few options:

1. subtract minSpeed from maxSpeed, multiply the result of that by the percentage you just calculated, then add it back to to minSpeed to get the speed your object should travel
2. use Mathf.Lerp(minSpeed, maxSpeed, percentage) to get the speed your object should travel

[simple sable]

I'll try that, thanks.

[somber nacelle]

actually you could even just use Mathf.InverseLerp to get the percentage so its even easier

[main shuttle]

This doesn't seem related to programming at all. Probably an #🔀┃art-asset-workflow question I think.

[simple sable]

I think I'm doing something wrong. If I drop the object from 180 or lower (which in my canvas that means [0, -180]) then I get 0.9, and if I drop it from above 180 ([0, 180]) then I get a value from 1.1 to 1.45, something like that.

[ivory sky]

Ow Thanks

[void basalt]

How does InputField.text work internally? Does it allocate new strings whenever you type something new? Or does unity avoid allocations internally somehow?

[somber nacelle]

you should probably just use Mathf.InverseLerp, but if you want to keep this method you need to get the starting distance not the starting position and divide that by maximum distance

[simple sable]

Oh, now it works. That's nice.

Thank you so much!

[knotty sun]

if you look here you will find the source code for Inputfield

[teal carbon]

if (_animator.IsInTransition(0)) // Build in method _animator.StopTransition(); // Non existing method
StopTransition() isn't a method. Any way to stop it? API only shows me a way to get transition info, no way to stop it.

[proper oyster]

What do you expect to happen when a transition stops?
Does the animation go back to the old state or the next state in where the transition leads to?

[teal carbon]

@proper oyster I'm controlling the animations through crossfades in code, but seemingly have issues with it where sometimes, when calling a new transition while already doing one, the newly called transition doesn't happen. Only happens every now and then but it still no good nonetheless. If I change all the crossfades to simply Play(), the issue is gone.

So I was hoping to stop any ongoing transition, before starting the next one, and that way keeping nice blending between animations while still being reliable

[proper oyster]

you could play the original animation to interrupt the ongoing transition
then you can transition to whatever you want

[teal carbon]

Thanks! Can be worth a shot indeed

[proper oyster]

not sure if it goes smooly or the animation is jumping when you call play on the current state again

if the transitions go from state to state via the animators parameters they can interrupt each other

[vestal crest]

i dont understand time.fixedDeltaTime. I dont use it in update but why and why i should not use deltaTime in fixedupdate

[somber nacelle]

you absolutely can use deltaTime in FixedUpdate, it returns the value of fixedDeltaTime when used in FixedUpdate

but fixedDeltaTime is the timestep setting for physics updates. Changing that value will change how often physics will update as well as how often FixedUpdate is called

you also wouldn't use fixedDeltaTime in place of deltaTime in Update because you generally want to scale things based on how long the frame took but fixedDeltaTime is not how long the last regular frame took like deltaTime is because physics and FixedUpdate (usually) do not happen at the same rate as Update

i have a 2d main camera

im trying to spawn enemies outside the main camera

my current script is as follows https://paste.ofcode.org/u3arrviHuad6GbTHqdRbz2

not sure what im doing wrong

[main shuttle]

What does happen?

Also, don't crosspost

[scarlet bane]

Sorry

Theys spawn in a region below the player

So i think my calculation is incorrect

[main shuttle]

Where is your spawn logic then?

[scarlet bane]

o sorry i got clipped out ill just send it here

GameObject newEnemy = Instantiate(enemy, new Vector3(x, y, 0), Quaternion.identity);

[main shuttle]

How big is your Orthographic size? Normally that's a small number

[scarlet bane]

5

[main shuttle]

            y = Random.Range(yStart-1, yStart+1);
            x = Random.Range(xStart-1, xEnd+1);

It's ystart and ystart, that's an error.

[scarlet bane]

oooo

XD

alright so i added the change

[main shuttle]

        float yStart = -cam.orthographicSize/2;

So that would be 2.5 then.

        float xStart = -cam.orthographicSize * cam.aspect/2;

This would be like 3'ish i would guess.
If you random range that, it would never be far from the player at all. It would always be around the center.

Also, cache the Camera cam = Camera.main;. No need to get that every frame, this is rather expensive.

[scarlet bane]

o so i shouldnt half it

alright

[main shuttle]

I'm just telling what I see your code doing.

im trying to spawn enemies outside the main camera
No where do I see logic that would accomplish that.

Even if this code would work, it would spawn it inside the main camera field.

[scarlet bane]

cam.orthographicSize that would give the hieght of the camera in world scale?

[main shuttle]

I do not know to be honest. Camera's don't have a height, but I don't know if an orthographic camera of 5 would view 5 Unity Units worth of information. Never made a orthographic game.
https://docs.unity3d.com/ScriptReference/Camera-orthographicSize.html

But you would need to calculate the edge of your view, and add those values randomly to your middle spawn point. Then it would accomplish what your original question asked. But I would expect there to be an example on google for something like this.

[scarlet bane]

based it off this and what i read from another site

[main shuttle]

https://stackoverflow.com/questions/44652296/spawning-zombies-just-outside-of-camera-bounds-in-unity

That should make it work. That code makes sense.

Hello. I have a parent object "car" that have component "rigidbody", then I have children "buttons". Rigidbody of the car eats all of my raycasts and I can't catch them in button class, how do I go around that?

OnMouseEnter, direct raycast, masks does not work, and I can't separate them too, because obviously the should move as a whole.

[vernal hornet]

Thread.Sleep? Might not work for you but that's what I can come up with rn

[orchid bane]

Will create my own one I guess

hi! i'm trying to make our value tempcolor.a to smoothly lerp between its value and either 0 or 1. currently it gets really close to said value (basically finishing the lerp) and then continuing for about 80% of the remaining time.
i'd guess this is related to time not being divided by the length, but that is something we do here.
any help is appreciated :]

   IEnumerator SetToBlack(bool fadeInOut){
        if(isFading == true){
            yield break;
        }
        boolConvert = fadeInOut ? 1f : 0f;
        if(boolConvertRef == boolConvert){
            yield break;
        }
        isFading = true;
        float time = 0f;
        boolConvertRef = boolConvert;
        var tempColor = image.color;

        while(time < fadeTimeToBlack){
            tempColor.a = Mathf.Lerp(tempColor.a, boolConvert, (time / fadeTimeToBlack));
            image.color = tempColor;
            Debug.Log(Mathf.Lerp(tempColor.a, boolConvert, (time / fadeTimeToBlack)));
            time += Time.deltaTime;

            yield return null;
        }
        tempColor.a = boolConvert;
        image.color = tempColor;
        isFading = false;
    }

[prime sinew]

i believe you need to cache tempColor.a to a variable and use that variable in the lerp first

[proper oyster]

dont use tempColor as the start value and the temp value

[prime sinew]

yeah, basically dont use the expected return value as part of the parameters

[slim spruce]

still get the same issue with

      while(time < fadeTimeToBlack){
            var startLerp = tempColor.a;
            tempColor.a = Mathf.Lerp(startLerp, boolConvert, (time / fadeTimeToBlack));
            image.color = tempColor;
            Debug.Log(Mathf.Lerp(tempColor.a, boolConvert, (time / fadeTimeToBlack)));
            time += Time.deltaTime;

            yield return null;
        }

[thin kernel]

Answering my own question. You can use "hit.collider.transform.name" instead of "hit.transform.name" and it will give the correct child object.

[slim spruce]

here's a video of the problem to try to illustrate it further

[leaden ice]

The time += deltaTime bit should be the first line in the loop

Also your starting variable is wrong

startLerp should be set one time before the loop and never change

It should not be fed from the function output back into the function

[slim spruce]

ah, that's totally it. thank you so much :]

[swift falcon]

Ugh I'm having a problem
I'm trying to make a space shooter game and when I started implementing some more bullet hellish patterns (nothing too fancy yet, just an enemy shooting in a full circle) I noticed that bullets started getting placed very unevenly
More enemies shooting in a circle and I'm getting unacceptable FPS drops
I didn't think I'd reach performance issues with only 100s of GameObjects!!! I thought I'd need hundreds of thousands gameobjects to reach performance issues!!!!

Side note, it's not the first time where the first sign of perfomance issues is that bullets are being shot slightly out of sync - no idea what causes this

I thought that using Time.deltaTime should even this out - I mean performance issues should manifest in FPS drops but NOT in different game mechanics

[thin aurora]

Create a timer, or create an async Task with a delay

Not sure how Unity handles asynchronous code outside of Monobehaviours, but it should be fine

[thin aurora]

Never use this pls

[lucid valley]

Do you have a pooling system setup for bullets and enemies?

Instantiating gameobjects is expensive, so reusing instead of destroying is a lot better

if you want hundreds of thousands gameobjects then you'll want to look into DOTS if you want the absolute best performance

I take it you have also used the deep profiling to know where you're performance drops are from. You can optimise a lot before thinking if you need to rewrite for DOTS

[swift falcon]

I don't. I just thought that since I was going to have only 100s, 1000s gameObjects at the very most I could just forget about performance and focus on implementing gameplay. Turns out it is not the case

[swift falcon]

Ouch. I'll have to look at my code because I do depend on OnDestroy in some places

[woeful leaf]

You can rework that with pooling as well

[swift falcon]

One thing I'm not really sure how to implement using a poolilng system. Enemy != enemy. A rocket that chases the player has different components and different child GameObjects than a turret shooting bullets at the player. If I used a pooling system I'd have to destroy and instantiate components, which kind of defeats the very point of a pooling system, doesn't it?

[woeful leaf]

You'd just have to check OnDisable instead probably

[swift falcon]

Honestly Unity's profiler is my enemy. I simply never learned how to figure out anything useful from the cryptic graphs and numbers it outputs 😦

[swift falcon]

AFAIK DOTS isn't stable yet?

[lucid valley]

you really need to look into a guide or video then to explain it then.

[lucid valley]

yeah, it's not 100% ready. But there have been popular games made with it already. But that is the way you'd go if you want the best performance

in my opinion DOTS is ideal for bullet hell games just thinking about how the systems interact

If your game is 2D then it would be harder

As there is no 2D physics system for DOTS yet, but if you only need collider checks (no collision / gravity) then making your own physics is relatively easy

[swift falcon]

But bullet hell games were made in flash 10-15 years ago and they were having far more bullets than I have so far!! and they were working fine

[lucid valley]

Yeah definitely optimise your gameObject version first. You should be able to get good performance

[swift falcon]

Yep, it is in 2D, however, I only use RigidBodies to detect collisions, I always set Transform.position and Transform.rotation manually

(I don't use forces nor RigidBody.velocity)

[knotty sun]

but we used completely different technology, not to be compared with Unity

[swift falcon]

Was Flash inherently faster than Unity? That would be counterintuitive for me, but well

[knotty sun]

Flash not inherently faster, the programmers that wrote it were inherently better

[leaden ice]

This is probably one of your main problems

If you just gave them velocity and let the physics engine handle the movement rather than doing a bunch of Update/FixedUpdate it'd be a lot faster

[leaden ice]

Time to learn. It's the only realistic way to optimize performance

Probably not

And the inexperienced ones probably didn't make well performing bullet hell games

[swift falcon]

Are you serious? Many Flash devs were artists with no programming background, they only learned the tiniest subset of programming knowledge that was absolutely necessary to complete their projects. Clearly I'm not the best programmer around, but hell, I think even I have more programming background than many Flash devs from the 2000s / 2010s

[knotty sun]

you misunderstand, I meant the programmers who wrote the flash system not those that used it

[swift falcon]

OK but then how to implement an enemy chasing the player? I must correct the angle at every frame anyway, this leads to Update

Same for fancy random movements, etc

[leaden ice]

I'm just talking about the dumb projectiles not the enemies

[swift falcon]

OK. So I guess no homing projectiles, but well, I don't have them yet anyway, so OK.

Hmm I now see I split behavior for enemies over many components, each with its own Update. An enemy ship called Basic Shooter has the following components: BasicShooter (its AI), MoveController (modifies Transform.position; the reason for splitting is ordering, I want first all enemies to make decisions what to do, and only then actually update the state of the game; I do not want non-deterministically first an enemy decidig what to do and updating it's position or firing a bullet, then the player ship moving, then another enemy moving while already operating on the partially updated state of the game - I don't remember why exactly I wanted to prohibit this, but I remember that there were some awkward edge cases and I decided that the way to have all weird edge cases off my head was to enforce strict ordering, first all decisions are made, only then positions are updated / prefabs are instantiated / etc); then the basic shooter has the EnemyShip component (contains all logic common to enemy ships, as opposed to asteroids and bullets); Oh and FireController split from MoveController to avoid god objects (FireController instantiates bullet prefabs, MoveController updates the ship's transform.position). Ugh, so I already counted 4 Updates per enemy

I guess this is bad?

[frigid wren]

does anyone how to find the source that causes warning Serialization depth limit 10 exceeded at 'UnityEngine.Events::ArgumentCache.m_ObjectArgument'. There may be an object composition cycle in one or more of your serialized classes.?

I would gladly solve it if I knew where to look

[lucid valley]

Isnt the most helpful of errors but its something like this

private class Foo
{
    private Bar bar;
}

private class Bar
{
    private Foo foo;
}

you are making a circular serialisation

You'll just need to check where you do some sort of implementation like that

[woeful leaf]

How do I solely move a box collider within code?

Slapping a collider on text but it's not all centered in the right way

I think .center exists but I'd want to just say align it with the left

[frigid wren]

I know what the error means. I just want to know where to find look for it to fix

[lucid valley]

if you check the editor log file it might have more info

theres a button next to the console to open it or go to the folder manually

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

[orchid bane]

If the error is really related to the depth of your serialisation then you can tweak somehow

[potent sleet]

just curious , but why colliders on text ?

[woeful leaf]

So they can collide with another UI object

And with the cursor to "pick them up"

[potent sleet]

ah ok , guess world canvas is out then :p

[woeful leaf]

Yeah it's screen space

[frigid wren]

sadly it does no not have enough information.

Serialization depth limit 10 exceeded at 'UnityEngine.Events::ArgumentCache.m_ObjectArgument'. There may be an object composition cycle in one or more of your serialized classes.

Serialization hierarchy:
11: UnityEngine.Events::ArgumentCache.m_ObjectArgument
10: UnityEngine.Events::PersistentCall.m_Arguments
9: UnityEngine.Events::PersistentCallGroup.m_Calls
8: UnityEngine.Events::UnityEventBase.m_PersistentCalls
Serialization depth limit 10 exceeded at 'UnityEngine.Events::PersistentCall.m_Target'. There may be an object composition cycle in one or more of your serialized classes.

[potent sleet]

you can use TextMesh mesh tho right?

[frigid wren]

if I could go to first item in serialization hierarchy that would probably help me

[potent sleet]

maybe align it would be easier

[lucid valley]

just guessing but do you use any custom UnityEvent<> anywhere?

[woeful leaf]

Which one?

[trim spoke]

You uploaded an APK or Android App Bundle which has an activity, activity alias, service or broadcast receiver with intent filter, but without the 'android:exported' property set. This file can't be installed on Android 12 or higher.

have anyone met this before? adding a screenshot of the androidManifest.xml file

[frigid wren]

I am almost certain that I do in fact 🙂

[woeful leaf]

I thought plopping a box collider around it would be most effective

As I don't want each seperate letter either or smth, I just need the general area so the player can pick it up

I've been trying to but I haven't really found concrete answers

Though maybe my search input is just poor, idunno

[potent sleet]

Oh for some reason I thought there was a newer version of TextMesh the 3D text thing

UI elements are just a pain

[woeful leaf]

Oh fun

I could technically make it world space I suppose, but that seems weird since the whole game is UI

[regal marsh]

I am having issues with an object. In this script line 93, I am getting the error that the variable 'buttons' has not been assigned and that i may need to assign it in the inspector. Is it not assigned in the inspector already?
https://pastebin.com/2QvKUDs6

[trim spoke]

element zero and 4 are blank

[woeful leaf]

Well element 0 and 4 aren't assigned

[regal marsh]

does that affect it?

oh wait

[woeful leaf]

If you reference that, ye

[trim spoke]

well yes you need to assign them for the script to have a refrance

[regal marsh]

i'm searching through it

shti

so i just put blank objects there and i should be fine?

[woeful leaf]

You could do that but you should replace them at some point ofc

[regal marsh]

Not every ui page will have a button to replace it with unfortunately

[trim spoke]

no. if you perform anything with those buttons in this script , you have to assign the button for it to know who performs the action. drag the buttons into the blank elements

[regal marsh]

i am storing them as gameobjects and not buttons so i could just use blank objects

[woeful leaf]

Then you should probably write the code differently

[potent sleet]

Worldspace helps aligning , easier to work with

[woeful leaf]

That's unfortunate

I might need to make that switch then at some point

[woeful leaf]

The only real way I can think of on how to fix it is to have the text as a child of a parent with the collider

since then each has their own transform

And then I can just tell the colliders transform to be the same as the child

As a start position

(or the other way around, it doesn't really matter)

Because I can't really find a proper way to move a collider itself, without moving the transform

Offset could work, but I've no idea how I'd calculate that

[potent sleet]

it could work easier having separate children, I def would give it a try with worldspace ui for 1 of them tho

[woeful leaf]

I know but it seems a bit whacky to move it to worldspace

[sterile glacier]

I added mirror to my game

How can i make it online on vps?

[oblique latch]

This might be more just basic math than Unity-specific, but is there an algorithm I can use to evenly space out a variable number of objects rotated in an arc around a player, maybe with a max rotation?
So if there's one object, it'd be rotated to 0 (directly in front of the player), if there's 2 objects they'd be maybe -30 and 30, if there's 3 they'd be -45, 0, 45. etc and then cap it around -90 and 90, so they'd never be behind the player. Right now I just have a hardcoded 2d array, but that doesn't seem like a great solution.

[prime sinew]

try this
https://forum.unity.com/threads/card-game-card-alignment.376446/

it seems like what you describe sounds like a hand of cards, so i went searching with that in mind

[pine spire]

@oblique latch don’t mean to sound rude, but did you just describe basic division

[prime sinew]

some form of trigonometry is involved I think, not quite basic

[dapper forge]

dont wanna be rude by interrupting some on going conversation here, but i need help and I need it fast as im doing my final touches on my diploma work before tommorows presentation and Ive noticed some strange behavior I cant fix by myself... idk why, problem doesnt seem to be comcplicated

My main menu scene starts with text asking to press any key, then playable director plays short sequence and main menu reveals itself, but when this scene loads itself again (leets say when I quit gameplay back to main menu) playable director wont start playing

public class MenuPressEnyKey : MonoBehaviour
{
    [SerializeField] TextMeshProUGUI text;
    [SerializeField] PlayableAsset animation;
    private PlayableDirector playableDirector;

    void Start()
    {
        text.DOFade(0, 1).SetLoops(-1, LoopType.Yoyo);
        playableDirector = GetComponent<PlayableDirector>();

        InputSystem.onAnyButtonPress.CallOnce((action) => {
            playableDirector.time = 0;
            print("MenuStart");
            playableDirector.Play(animation);
            playableDirector.Evaluate();
            //text.DOKill();
            text.gameObject.SetActive(false);
            enabled = false; 
        });
    }
}

[pine spire]

@oblique latch Sounds about Clamp(amountOfObjects*radiusAdditition,180) / amountOfObjects, divide the clamped value by two to get starting angle.

[dapper forge]

code is really short and basic

also this Tween on TMP doesnt play in this scenerio

ignore prints and comments, ive benn trying to debug this for a while :/

[pine spire]

@oblique latch placing it around the player can be done with some basic trigonometry, if you google placing point on circle it will be probably be the first answer. Unity likely has some built in vector function for it too

[oblique latch]

@pine spire Thanks. Yeah, I don't even need that much, I've already got them setup with offsets and rotation centered in local space, so it's just a matter of setting a localEulerAngle for each. But what's radiusAddition there?

[fervent burrow]

Hey there, I have an enemy AI problem where enemies start walking sideways when they collide against an object for some time, it's a 3D project and I´m using NavMesh for the wandering movement, and they sometimes stop walking when they go against a non-walkable area... I´m new to Unity and I don't know much about AI, does anyone have any advice on what to do?

I also tried to add NavMeshObstacle component to the objects so the enemies would try to avoid them, but they still get stuck or bugged sometimes

[potent sleet]

make a short video

[fervent burrow]

https://gdl.space/axikozebuc.cpp

this is the code I have for enemy movement

[rich harbor]

Could use some help figuring out making my projectiles function. I'm just not really sure how to go about some things. Mainly thinking about collision with an enemy and dealing damage. This is what I have so far for my Projectiles class: https://pastebin.com/qKigXJjg. It's the base that I'm gonna use for all my projectile scripts. Now, the thing I'm trying to figure out is that in some cases I'm going to have a very slow moving projectile that should hit an enemy multiple times with damageCooldown. That's also there so I don't have projectiles hitting the same target multiple times too quickly for other cases. Should I just be tracking what colliders I am currently colliding with? Or should I check every update if it's been long enough for all my entries in entityDamageTimes?

I guess I'm also unsure how I should be checking collisions exactly.

I'm sure the way I'm doing everything in my projectile code is completely wrong and I could use any feedback I could get

[fervent burrow]

As you can see, the enemies sometimes just get stuck or start moving kinda sideways

[simple mountain]

I dom t understand anything about your code, that s on me but the idea behind not hitting the same enemy twice is either to make a list with objects that where already hit, or make a cooldown, that is cheaper but it is worse another I idea I have is maybe have the bullet skip a few meters when it hits something but that s not going to look very clean

[potent sleet]

this can help you space out points around your player NavMesh.SamplePosition

[oblique latch]

They look like they're moving sideways because you have them moving straight towards the player but they're not turning fast enough to face him

[rich harbor]

entityDamageTimes is the list of enemies hit paired with the time that they were hit

[fervent burrow]

even If I stop they are still sideways, I think when they collide with something it may mess up they rotation

[fervent burrow]

where should I use that?

on the Patroling function?

[potent sleet]

do you have rigidbodies on the those

[potent sleet]

use it when enemy chase player make points around player so they are spaced out

give a same target with slight offset each ai

[fervent burrow]

the NavMeshObstacle component already spaces out enemies a bit, so when I stop they try to form a circle around me

[fervent burrow]

ye, the enemies have rigidbody, but the player has a CharacterController

[potent sleet]

lock the rotation/position constraints

[fervent burrow]

I have it like this for the enemies

[potent sleet]

why

this what makes ur enemy rotate when it hits things

[fervent burrow]

so they dont go up or down and to avoid seeing them go sideways when they go against something

[potent sleet]

navmesh agent alreeady dont need rigidbody..

[fervent burrow]

should I unfreeze the rotations?

[potent sleet]

not at all

use it only with constraints if you must on navagent for collision messages only...or interacting with physics in scene

Lock all constraints you will not got them rotating sideways

& gravity should be off if it wasnt already.

[fervent burrow]

idk if this may be usefull, but I created and empty object that has the enemy inside, because of a rotation problem... the empty object has the navmesh components and the enemy itselft only has collider/trigger and rigidbody

[potent sleet]

alr you do you lol i told you having rigidbody control rotations on navagent makes about sense as third coat of paint

[fervent burrow]

all of them?

[potent sleet]

yes

[fervent burrow]

uhh the enemies started going crazy

they start nice, but then start going around like drift cars xd

[oblique latch]

How are you using a navmesh on an empty gameobject? How are you moving the enemy meshes to the empty object then?

[potent sleet]

can you show full inspector for enemy

[fervent burrow]

the empty object is a parent of the enemy itself

[oblique latch]

Or do you mean you have a rigidbody as a child of the navmesh component? Because then you should check if bumping into things is misaligning your rigidbody and it's not pointing straight anymore, even though the parent might be

Are you checking if the local rotation of the child is changing then?

[fervent burrow]

Inimigo means enemy in portuguese

this is what I have on the enemy itself

this what I got on the parent (empty object - no longer empty)

[oblique latch]

Put your constraints back the way they were, run the game, pause it when you see one moving sideways, and look at its "Iminigo" object local rotation in the inspector.

[fervent burrow]

do I keep the gravity turned off like Null said?

[oblique latch]

Well if you're locking their Y position, gravity's not really doing anything to them anyway

[fervent burrow]

it actually makes them not go crazy

if I turn it off they go crazy

[fervent burrow]

they have different rotations

when walking sideways

[oblique latch]

Now if you click on the parent object, is its rotation correct (Facing the direction it's moving?)

[fervent burrow]

the rotations are different

from InimigoDireito and Inimigo

originally Inimigo has Y 90 on rotation

and the InimigoDireito has Y 0

[oblique latch]

Yeah, what Null was saying is you don't really need a rigidbody on the child, or if you do maybe have it kinematic, because it's rotating around from collisions.

[fervent burrow]

what's kinematic?

[oblique latch]

Means it won't move

[spark pond]

Does anyone know if there is a way to set command line args within the Editor to be passed in when playing in the Editor? I am looking to use some cmd params from a build server run to use in my tests.

[fervent burrow]

I believe the enemy rotation problem is fixed

I also froze the Y rotation

thank you

and what about the enemies getting stuck on non-walkable areas?

[oblique latch]

Np. Not sure about that, but as a suggestion that might help, for those enemies I'd recommend a sphere or capsule collider anyway

[fervent burrow]

should exist a cilinder collider

you think changing from box collider to sphere or capsule could help?

I don't know what the difference is on this aspect

because even with a different collider the enemy may still walk into those non-walkable areas and stop

they are still trying to go to the destination of their pathfinding

I believe that's what's happening

I´ll still try your suggestion, may actually work

Thanks again

[fallen lotus]

hey guys! this could be being tired this morning but I wanted to ask what your guys solution would be. I have a function that is called that passes in a string value. I then use a switch statement to do somehing depending on what the name is, then inside of each case statement, i need to then again check what the number is. It'll be 8 numbers I need to check against. and for the possible string values, there are 4 string values? let me know if you need clarification

[leaden ice]

This question is extremely vague, but it seems like a pretty inefficient way to do things

1. why use a string instead of an enum
2. What are the different behaviors? How different are they?
3. not sure what you mean by "numbers" here

[fallen lotus]

thats why i wanted to ask for a better way. ill send some code for what im trying to do and it might make more sense. SOrry im really terrible at explaining things so showing you might be the best option. Also i've never used enums so i can look into that

[fallen lotus]

heres what I thought I could do but I know its super inefficient so I wanted to see if there is a better way

https://pastebin.com/NudRfNbk

let me know if you have clarifying questions

id have to do that long string of numbers for each name case

i also was thinking I could make an equation that outputs the desired decibal value based on the the value inputted but im just not the best at math right now lmao

[leaden ice]

int result = (8 - sliderValue) * 10;
mainMixer.SetFloat("Master", result);```

replaces that entire switch

[ionic hawk]

Can anybody help me please?

[fallen lotus]

why couildnt i think of that lol

[ionic hawk]

like I got the configuration set to maximum possible (scripting runtime version)

[lucid valley]

what unity version are you using?

[ionic hawk]

2018

thats what my project was created in

I basically found it on a old usb

and trying to make it run gagin

*again

[fallen lotus]

how do I convert that equation into an int? cause its going from float to int

[leaden ice]

Mathf.RoundToInt or CeilToInt or FloorToInt

as you wish

[fallen lotus]

which one is less performance intensive

[fallen lotus]

oh and i would need to put a - sign on the left of the left parenthasis

perf

[lucid valley]

if you don't care about the value after the decimal you can also cast to (int)

[fallen lotus]

yeah its always a whole number

[leaden ice]

not relevant

don't worry about it

[fallen lotus]

kk

[fallen lotus]

itll also never output a decimal since its a slider value checked to output only whole numbers

itss just cause unity stores that value as a float since sliders have the ability to do decimals i assume

[grim marlin]

Hello, I am trying to use a Physics.SphereCast in my game, it works.
But is there any way to visualize it ? as there is no graphic debut I think. I would like to adjust it size if possible(hard to do it without seeing.).

[leaden ice]

Window -> Analysis -> Physics Debugger

in those options there's a setting to visualize queries

If that's not your speed there's also this package by a resident of this discord:
https://github.com/nomnomab/RaycastVisualization

[grim marlin]

Thx a lot

[ionic hawk]

anyone knows why Im getting an error?

[leaden ice]

read the error message

[ionic hawk]

Assets/Scripts/ratController.cs(116,46): error CS1644: Feature `out variable declaration' cannot be used because it is not part of the C# 6.0 language specification

[leaden ice]

it means you need to declare the variable on an earlier line

since your Unity version is too old to declare it there

[ionic hawk]

oh ok thanks

[leaden ice]

so like:

WhateverType hit;
NavMesh.SampleWhatever(..., out hit, ...);```

[ionic hawk]

and what do these mean?

[leaden ice]

it means you can't use return ref xxx; or ref int x = ....;

[ionic hawk]

ok thanks 🙂

[ionic hawk]

@leaden ice (sorry for the ping) Do you know why I cant import PostProcessing even if I have it installed?

[leaden ice]

is it an error only in VS or in Unity too

[ionic hawk]

unity is full of this garbage too

[leaden ice]

you have this package installed? https://docs.unity3d.com/Packages/com.unity.postprocessing@3.2/manual/index.html

[ionic hawk]

OHHHH wait

[leaden ice]

Do you have an assemvbly definition file or something?

[ionic hawk]

I downloaded it from github and Im FINALLY left with just one error

Im only left with this

[fallen lotus]

going back to this @leaden ice, what would be a similar equation that i could use if I wanted to plug in the decibel value and output the slider value?

[leaden ice]

idk man, think about it 😛

[fallen lotus]

my brain 😢

[lucid valley]

maybe two scripts called the same thing in the same namespace?

[fallen lotus]

int decibelValue = Mathf.FloorToInt(-(8 - sliderValue) * 10);

but if I wanted to plug in decibel value into a new equation I need to output the slidervalue

hmmm lol

[hexed pecan]

Yep looks like you have two scripts named ExampleWheelController

[ionic hawk]

ok thanks

[regal marsh]

if an object has multiple colliders can you specify which one you want to use in ontriggerenter

is it just making only one of them a trigger

[leaden ice]

All colliders under a given Rigidbody will be grouped

you will get OnTRiggerEnter for any of them

if you want to only capture the event for a specific one, you'd need to put it on a separate child object and have the script that has OnTriggerEnter be on that object directly

[regal marsh]

ok that's what i was planning on i just wanted to make sure i wasn't making extra objects for no reason

thank you

[thick socket]

Scriptable Object-I have a large enum but I only want to give the option to pick like 2 or 3 of these enums in the inspector, how could I do this?

ex) only the 2nd, 5th and 7th

[leaden ice]

custom property drawer

[thick socket]

is there an easy way to use that to make it like this?

all Im seeing adds like 30-50 lines of code extra

which seems insane

[leaden ice]

it's easy if you're accustomed to writing custom property drawers

[thick socket]

I have NaughtyAttributes

maybe I'll see if I can use that somehow

[thick socket]

yeah, never even looked into those before

[leaden ice]

Yeah could do it with https://dbrizov.github.io/na-docs/attributes/drawer_attributes/dropdown.html

[thick socket]

awesome thanks, I had actually just found that also 🙂

have done very little with all this so forgot NaughtyAttributes was a thing lol

[regal marsh]

I have a working collider child now that only detects an object within the area but for some reason the world center of mass is constantly increasing which causes it to move up gradually. Freezing the y position seemed to work but the child started rolling away from the parent after a bit when colliding with the target object

So I don't think that freezing the y position really works because the world center of mass changes even if it is frozen

[leaden ice]

the world center of mass is constantly increasing
What do you mean by this? How are you measuring center of mass?

What are you actually trying to do here?

[regal marsh]

on the rigidbody

[leaden ice]

What does "detecting an object within the area" have to do with all this motion

[regal marsh]

the child trigger i was telling you about before

the navmesh agent doesn't move unless something enters the trigger

and it moves towards that agent

[leaden ice]

the center of mass will only change if you:

• change it yourself in code
• add or remove child colliders

[regal marsh]

i am talking about the center of mass of the child collider

it is changing constantly for some reason

[leaden ice]

colliders don't have centers of mass

only Rigidbodies do

[regal marsh]

the rigidbody of the child

[leaden ice]

I'm trying to figure out what you mean by center of mass here

why does the child have its own Rigidbody

[regal marsh]

because it has a separate collider from the parent

[leaden ice]

that's not how it works

you should only have one Rigidbody

on the parent

all the colliders under it are considered part of that body

including in child objects

[regal marsh]

oh okay

the object technically behaves the way it's supposed to now that i've removed it but the rigid body's values under "info" all freak out unless i freeze position and rotation

[thick socket]

how do I get a switch statement to autopopulate

public Items(string idTmp, MyItemType myItem, MyItemRarity rarityTmp)
    {
        switch (myItem)
        {


        }```

I just want to switch based on the different MyItemTypes

[carmine cloud]

when something says Object(clone)(clone) what exactly does that mean? I mean I know the item is a clone of a clone but why does unity track that?

[leaden ice]

In Rider like this

[simple egret]

VS will report a suggestion for you. Look for the 3 dots under the switch keyword, hover, lightbulb, "Populate switch"

[leaden ice]

it means you cloned a clone. Whenever you call Instantiate it adds Clone to the name

Generally if you cloned a clone you're doing something wrong

[thick socket]

thanks, its somehow working now

not sure what changed but it didn't work like 2s ago

[simple egret]

I think it does that if you use the snippet also, like switch [tab*2], type the variable name, [enter]

[thick socket]

switch (myItem)
        {
            case MyItemTypes.Armor:
                iType = ItemType.Armor;
                ePart = EquipmentPart.Armor;
                break;
            case MyItemTypes.Helmet:
                break;
            case MyItemTypes.Jewelry:
                break;
            case MyItemTypes.Weapon1H:
                break;
            case MyItemTypes.Weapon2H:
                break;
        }```

is there going to be a better way to doing this?

going to have to do the itype and epart for each line for the different types

[carmine cloud]

it happens when I split a stack of items in my inventory the base is always a "clone" since it's an instance of a scripted object so, no worries about it being wrong. I was mostly just wondering why unity would track that.

[leaden ice]

Make an extension method/mapping elsewhere for MyItemTypes -> EquipmentPart and MyItemTypes -> ItemType

then you can skip the switch and do

[full scaffold]

interface

[leaden ice]

iType = myItem.AsItemType();
ePart = myItem.AsEquipmentPart();```

[simple egret]

Hm not really. If you're more into switch expressions you could use that + tuple madness, like so:

(iType, ePart) = myItem switch
{
    MyItemTypes.Armor => (ItemType.Armor, EquipmentPart.Armor)
    // ...
};

Though why 3 enums that for me, say the same thing? Armor is armor

[thick socket]

yep

[leaden ice]

yeah seems like there's at the very least a redundancy betwen ItemType and MyItemTypes 😵‍💫

[thick socket]

working with someone elses asset code and it requires these 2 different things

could probably get down to 2 enums tho

[simple egret]

If the enum values are laid out the same, you can try a very cursed cast operation like iType = (ItemType)(int)myItem, though that will break if one of the enums is reordered

[carmine cloud]

I'd consolidate to one on your end, instead of a whole new type just add an extra attribute so you know where to pass it when you interface with that persons asset code

[thick socket]

like extend their enum somehow?

[simple egret]

Yeah using an extension method that allows this ^

[rough brook]

I need my pain to be eased

[simple egret]

Something on line 34 of the Projectile class is null

[rough brook]

the full script is commented out. how on earth does it have an error?

[carmine cloud]

cough

did you save after you commented it out

[rough brook]

yes

[simple egret]

Make sure you saved. Select the script in your Assets, does it show the commented code there as well?

Also commenting out the whole class will break scripts attached to your game objects

[leaden ice]

if the script is commented out you've got problems because now there's a broken ass unlinked script on an object somewhere

[thick socket]

if some of this guys asset code wasn't dll

I would probably strip it to a minimum and rewrite it

its done so horribly rn lol

[rough brook]

well uncommented it

line 34 is still commented out and it still has an issue with it somehow

[carmine cloud]

that's not the issue, if you commented the script out and still got the error after saving, then it means an object in your game is linked to a different version of the script that isn't reflecting your changes

[simple egret]

Select the script in your Assets, does it show the commented code there as well?

[carmine cloud]

hence the "broken ass unlinked script" comment

[rough brook]

yes

[simple egret]

Triple-check that you're modifying the right script

[carmine cloud]

I'd guess your spawning prefab projectiles and you probably have a prefab variant hanging around with a reference to the wrong script version but that's just a guess

[rough brook]

theres only 1 projectile script

[rough brook]

i pressed edit on the script of my prefab and it shows it commented out

theres only a bracket on line 34 i realise

[simple egret]

Within Unity, move the script to another folder, and back. This will trigger a compiler pass, maybe that'll wake it up and fix it

[rough brook]

still the exact same error

I swear coding leads to madness

[simple egret]

Copy the script contents to Notepad or something, then delete the script. Run the game, you should get a few warnings. If you still get the error, you're modifying the wrong script

[carmine cloud]

when calling OnTriggerEnter from a script then it has to be attached to an object that has a collider since it's saying the null reference error for the whole function - i.e. line 34 then it most likely means it can't find the collider object

[simple egret]

Nah the code was offset one line, PlayerHealth was null

[carmine cloud]

but! you still have an issue of broken script links if you triggered the error when the whole script was commented out

[simple egret]

Yeah, drag-drop the projectile script on the target object and get rid of any missing compoents

[carmine cloud]

huh, I see where its like that in his first screen shot

🤷‍♂️

[simple egret]

Never seen that happen in the past lol

Usually a recompilation fixes it, but here it fails

[rough brook]

il try disabling what uses the script

[rough brook]

target object?

[simple egret]

The Game Object that is meant to have the Projectile script attached

[rough brook]

no difference

[simple egret]

Confirm the path of the script you're fiddling with right now, find it on your computer via your Explorer and post its path here

You can remove everything before /Assets/

[rough brook]

collider is here

I need a variable for the collider maybe?

[simple egret]

You need a reference to that PlayerHealth variable. Uncomment it and drag-drop the script onto the Projectile inspector

It should appear right above that projectile speed field

[rough brook]

wont let me drop it into the box

[simple egret]

Well at least that means your script compiles and Unity has the latest version

[rough brook]

when open the downward thing is says assets none as if it wont accept anything

[simple egret]

You need to drag-drop the script from an object in the scene, if the Projectile script is on an object in the scene

[rough brook]

it wont accept anything whether its object or script

[simple egret]

Where are you dragging from?

Which object, is it in the scene? Is the Projectile script also in the scene?

[rough brook]

I have tried assets and I have tried my scene

[wispy mesa]

does anyone know the path of this :

[simple egret]

Please answer the questions

[rough brook]

you can put scripts in the scene?

its not in the scene

[simple egret]

On a variable of type GameObject, call SetActive(true / false) to enable, disable game objects

[wispy mesa]

ok thanks

[simple egret]

You know what I mean, the script is on an object that is in the scene

[rough brook]

yes

set it to inactive. nothing changed

[simple egret]

What, inactive?

[wispy mesa]

menu.SetActive() == false does this work for if statements?

[rough brook]

I ticked it off so nothing in it runs and it doesnt show

[leaden ice]

no... SetActive doesn't return anything

It sets something

[wispy mesa]

ye i see but is there any way i can see its state

[leaden ice]

of course

activeSelf or activeInHierarchy

[wispy mesa]

alr sir

ty

[simple egret]

Okay actually answer the questions.
The object you're dragging from: is it in the scene? Does it have a PlayerHealth script on it?
The object you're dragging to (that has the Projectile script): is it in the scene?

[rough brook]

I am genuinely trying but I dont understand at all. do you mean dragging to this?

[simple egret]

Yes

[rough brook]

I cant drag anything into it

Anything

[simple egret]

I know that

That's why I'm asking where are you starting the drag with your mouse

[rough brook]

the player has a health script

[simple egret]

Okay and the projectile script is on which object?

[rough brook]

the projectile prefab. this was all working only hours ago

[simple egret]

Ah there we go, answers to the question I asked 10 minutes ago

You cannot drag an object that is in a scene, to a script on a prefab

[rough brook]

hm

[simple egret]

You'll need to tell it which health script it is, fully from the code, when you Instantiate the projectile

Or when you collide, would be the better option, since the projectile will hit something

[rough brook]

I managed to drag the player prefab into the box

[simple egret]

Yeah but that won't work as when the player is instantiated in the scene it won't magically replace the one in your projectile script

OnTrigger/CollisionEnter you will get the other object your projectile collided with. From there you can try to get a Health script on the object, and deal damage

[rough brook]

If its showing the same error regardless of whether the script is commented out, arent I fucked even before changing any of that?

[simple egret]

Share the up-to-date error, and the up-to-date script

Also make sure the error is even recent, maybe it's one from 10 play sessions ago you didn't clear from the console

[rough brook]

the error is unchanging

w8...

[simple egret]

That would be an error from 3 minutes ago roughly, accounting for time zones

[rough brook]

wtf does it work?! it gives a red error for the script but works when I press play

[simple egret]

Clear the console and run the game, then post the error

[rough brook]

ty so much for your help. how to clear console?

[simple egret]

Button labeled "Clear" on its top-left corner

[rough brook]

Can you imagine how unbelievably dumb I feel at the moment? I was trying to fix an error that wasnt there. I just cleared the log and its gone.

[simple egret]

Now you'll know, errors include a time stamp for that reason

[tropic sleet]

There should be another button around there that lets you clear the console when you enter playmode, if you're not using that already. That way errors will only be relevant to your most recent session (or to the editor).

[plain haven]

im having an issue where my bounce pad's bounce heights are inconsistent, one time theyll be shorter like i want it to be, and other times it will launch me into space

[rough brook]

errors usually clear on their own

[simple egret]

No, they don't

Not until you clear them yourself

[rough brook]

thats what I experience

atleast usually

[simple egret]

If you have "Clear On Play" enabled then yeah they will clear when entering play mode

There's also the sometimes handy "Error pause" that will pause the game when an error pops up

[simple egret]

You'll have to show some code, otherwise we can't help. Post the one that adds force to the player when a collision is registered (or however you're detecting that the player entered the bounce pad)

[plain haven]

//bounce check
        onBounce = Physics.Raycast(transform.position, Vector3.down, playerHeight * 0.5f + 0.2f, Bounce);

thats the code that checks if the player is standing on an object on the "Bounce layer"

        if (onBounce)
        {
            rb.velocity = new Vector3(rb.velocity.x, 0f, rb.velocity.z);

            rb.AddForce(transform.up * bounceForce, ForceMode.VelocityChange);

            canBounce = false;
        }

then thats the one that adds force to the player

    private void ResetBounce()
    {
        if (state != MovementState.air)
        {
            canBounce = true;
        }
    }

that resets the bounce

[simple egret]

Here you can combine the two rb. calls into one. It's never good to fiddle with both the velocity and the force application at the same time

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

See if that solves it first. Then you can try to orient the force relative to transform.up

[plain haven]

that seemed to fix the height, but now it seems to be pushing towards a direction in worldspace

wait nvm it didnt fix the heights

this is what i did

        if (onBounce && canBounce)
        {
            //rb.velocity = new Vector3(rb.velocity.x, 0f, rb.velocity.z);

            //rb.AddForce(transform.up * bounceForce, ForceMode.VelocityChange);

            rb.velocity = new Vector3(orientation.position.x, bounceForce, orientation.position.z);

            canBounce = false;
        }

[simple egret]

Maybe it's applying other forces to it at the same time?

Like, movement forces

If you plan on using the rb.velocity, you should do it once. Beforehand construct a vector that will accumulate all the forces (movement, jump, etc.) and set the velocity once, at the end of the method

Else you can use AddForce, but use that everywhere. No mixed up velocity changes and AddForce calls for the same rigidbody, or else your force changes will conflict with themselves

[plain haven]

the rb.velocity was only used to reset the y velocity, i copied it from my jump code, where it works just fine in combination with an rb.addforce

[simple egret]

Okay, then post the whole class in a paste service

[plain haven]

the jump class?

[simple egret]

Yeah, the one that has all the small snippets of code you posted earlier

[plain haven]

all my movement code is in one class that has the same name as the script

[simple egret]

Yeah, so that one

[plain haven]

https://gdl.space/ifayosikuk.cs

that should be it

[simple egret]

Yep that's a fat movement script there, even has a state machine
Give me a moment

[plain haven]

ok

[rough brook]

less coding focussed but how do none of you go crazy coding? although my problem was very simple to solve it still took me a good amount of time and I could definetly feel stress over it

[plain haven]

we do

[leaden ice]

you learn and get better and problems become easier

[plain haven]

or that

that works too

[carmine cloud]

I'm stepping through several hundred lines of code if you don't think I'm crazy then you should re-evaluate your definition of crazy

[simple egret]

Okay so we're going to do it the easy way, that is turning off all features, and turning them back on one by one, until the issue appears again.
First candidate: speed limiter. Comment out line 166 and try again

[leaden ice]

all in a day's work as a software engineer

Debugging itself is a skill though

which you also get better at over time

[carmine cloud]

oh I know I've been at this for 13? years now

I forget lol

[rough brook]

I think I understand why not a lot of people get into coding lol

[leaden ice]

It takes a certain kind of mind.

[rough brook]

I will have to build the right mindset for sure

[plain haven]

doent seem to be the speed limiter

[simple egret]

Okay move the player right above the bounce pad in the scene view, and disable everything except the lines 148, 150-159

Even stuff in FixedUpdate, anything that could be adding force or touching the velocity. You can force canBounce to true so you can make consecutive jumps

(Offline for the night, someone else will take the lead)

[pine spire]

At the moment I do. Then I take a break from learning UE/C++ combo and have some fun with Unity 😂

[cobalt wraith]

Heya! I'm trying to use lerp to rotate my camera into position, but I'm having issues, could someone take a min and try to help? ^^

This is the code that's causing the issue

_lookAt.eulerAngles = Vector3.Lerp(_lookAt.eulerAngles, new Vector3(0, 0, 0), 5f * Time.deltaTime);

My camera is attacked to an empty, which I rotate to rotate camera, but if I try to run that code above, but the x value is less than 0, the camera spins out

[sterile pelican]

Try smootdamp

[cobalt wraith]

I asked Openai

This worked

[sterile pelican]

😎

[cobalt wraith]

Better than Google 😎

[sterile pelican]

Yep

Save yourself the time and just get ChatGPT to make your game 😆

[hexed oak]

if it's not overloaded

[cobalt wraith]

True

[quartz folio]

You should really just be using Cinemachine, which lets cameras be extremely flexible and driven with little to no code

[cobalt wraith]

Probably true, but it's working now:D

[swift falcon]

I got this script from github and it looks good to me, but when I try loading an array from a json file, it returns null

This is the json file

I am only testing so the data will be changed

How I use it in code, I have this in start function

[quartz folio]

Did you serialize it using the ToJson method?

Because that doesn't look correct to me

[swift falcon]

No, I have it already written

Then I read it with the jsonHelper.FromJson

[quartz folio]

You should serialize something and that'll make it pretty apparent what you've done wrong

[swift falcon]

ok, I will try that

it returns {}

I put an item in the array and I tried the ToJson, and it returned that

[quartz folio]

Is scenario [Serializable]?

[swift falcon]

yes

[quartz folio]

well that ain't right. The issue with your original Json is that nowhere do I see Items

[swift falcon]

So I need to replace "scenarios" with "items"?

[haughty fiber]

Hey all! Need help with a bit of a math conundrum I'm dealing with.

For context: this is the script that performs a x-z movement system with slight momentum when starting and stopping movement.

tempMoveVelX/tempMoveVelZ = values that dictate the movement direction. -1 if in the -x/-z direction, 0 if not moving at all, and 1 if moving in the +x/+y direction

moveSpeedX/moveSpeedY = the current value of each direction's speed. Ranging between -maxSpeed and maxSpeed (determined elsewhere in the script)

All of this is then plugged into a simple characterController.move(...)

I did this with the help of another user, but now I'm running into the age-old issue of movement being faster in the diagonal direction than in a singular direction. I see WHY this is happening, but am having trouble coming up with a viable solution.

Anyone able to help me out?

[swift falcon]

so how can i resolve the issue

?

[quartz folio]

capitalisation matters. So no, Items. But you should really be figuring out why it can't serialize, because that's a major issue, and you won't be able to debug the failure without having something valid to compare it to

[leaden ice]

rather than normalizing your input vector you should use ClampMagnitude

[haughty fiber]

I honestly didn't even know that function what was a thing. How do you suggest using it here?

[swift falcon]

{"Items":[{"id":0,"text":"test","popupText":"text","conditions":"conditions"}]} I got that after using JsonHelper.ToJson

[leaden ice]

Vector3.ClampMagnitude(myInputVector, 1)

[quartz folio]

Great, now you can see what structure you need.

[swift falcon]

Thanks for the help.

[haughty fiber]

If you're talking about using it for the first line in my screenshot, it still comes up with the same result when moving diagonally. That being changing (1, ..., 1) to (0.71, ..., 0.71)

[leaden ice]

yeah (.71, 0, .71) has the same magnitude as (1, 0, 0)

so the issue of moving faster diagonally should be solved @haughty fiber

[haughty fiber]

In theory, you're right. The issue arises in the code below it. The magnitude of the finalMove vector at the very end when moving in one direction seems to fluctuate between 0.15-0.17 (lower number is due to multiplying by deltaTime). But when you move diagonally, it seems to average between 0.25-0.30. The issue comes from the last 3 lines

[leaden ice]

It shouldn't... the thing that could happen is if moveSpeedZ and moveSpeedX are different then you'd get a different speed going on x than on z

and in the middle it should be... about the middle of those two

[dusk apex]

You've normalized the vector to get the direction that's uniformed but have modified it's x and y components - separately. This will make the resulting Vector have variable speeds rather than consistent. Instead you ought to just have a final movement speed and multiple the Vector by the scalar to get uniform movement in x and y - circular/spherical fixed distance.

[haughty fiber]

moveSpeedX/Z are, at least from what I've made, going to be different a lot of time. I tried to make it that way so there would be a slight amount of movement momentum when stopping or changing direction. I did it with X and Z separately so that, for example, if you were moving diagonally and switched to moving only in the x-direction, you would keep going a very slight amount still in the z direction instead of instantly snapping

[dusk apex]

If the two values are the same, x and z scalars, you'll get squared or cubic movement at best.

[haughty fiber]

That's what I had before I tried to implement the above-mentioned movement momentum. Probably gonna have to work on a way to mix the two

[leaden ice]

I don't see what that has to do with having separate x/z speeds

If you want momentum that happens at a completely different place. This is just establishing an input vector

[haughty fiber]

Let's take moveSpeedX for example. When you aren't moving, it's 0. As you move in say the +x direction, it will rise steadily up to the max speed value. And when you stop, it will steadily lower back down to 0

[leaden ice]

I think you're mixing metaphors here

[haughty fiber]

Think I might be

[leaden ice]

I'm expecting moveSpeedX to just be some overall input speed multiplier than doesn't change.
You're talking about the actual current movement speed of your character

that would not be handled at this layer

this is what I normally would expect for building an input vector:

Vector3 input = new Vector3(rawInput.x, 0, rawInput.y);
input = Vector3.ClampMagnitude(input, 1);
input *= myObject.rotation * input;```

only then would you take that input vector and do something like:

myRb.AddForce(input * speed);```

[haughty fiber]

Okay I see what you're saying. And then take the resulting input vector and multiply THAT by the speed?

Okay that makes a lot of sense

[leaden ice]

or:

myRb.velocity = Vector3.MoveTowards(myRb.velocity, input * speed, Time.deltaTime * acceleration);```

but yeah the current speed of your character should not be fed into the input calculation

[haughty fiber]

I get what you're saying. Thanks for helping out!

If I could ask though, just as a piece of advice, how else would you suggest implementing movement momentum, or whatever you would call the player not immediately stopping/starting

[leaden ice]

Both of the little examples I just gave will give you movement with momentum

basically just ... don't instantly set your new velocity to whatever is dictaed by the input

move to it over time

[leaden ice]

such as like this

If you're not using a Rigidbody, you will have to track current velocity yourself if you want momentum

[haughty fiber]

That's kind of what I'm already doing though. MoveSpeedX/Z aren't determined by the script I sent you. They're determined elsewhere and used here

[leaden ice]

yeah that's the issue though, you're using the current speed in the input calculation

that's backwards

the input should be influencing the current speed. The current speed should not be influencing the input

[haughty fiber]

And it wouldn't work if, instead of multiplying speed here, I instead scaled the input vector by one containing (moveSpeedX, 0.0f, moveSpeedZ)?

[leaden ice]

no that's just weird

my speed is a "desired speed" kind of thing. Your fields are "current speed"

right?

[haughty fiber]

Because although X and Z will be different in concept, at full speed (which is reached in <1 second), they will become the same

Essentially yeah

[leaden ice]

I don't see why you would multiply the current speed into that, no

it doesn't make a whole lot of sense

it would be like... if your speedometer controlled your gas pedal in your car

[haughty fiber]

That's true. I guess I'll work on it for a little bit and see if I can find a better solution

[rich leaf]

Hey I have a question regarding ray casting. I am Storting the ray cast hit information in a variable called “hit”. I want it set up such that if the ray cast hits a certain type of game object, it checks to see if a public Boolean value in a script attached to said object is true or false.

When I do hit.transform.gameobject.getcomponent<script>().boolean, I am getting an object reference error at runtime

[leaden ice]

Shouldn't crosspost

I posted in the wrong channe

hey having some trouble on my unity lesson im new but im in 2.4 section go my scripts working but cant get the spawn animal part to work it suppose to spawn a animal every few second but they all spawn in like crazy need help please still learn

[leaden ice]

you shouldn't crosspost either

[fervent scarab]

sorry wasent sure wich one was the right one kinda new to using disocd wont happen again

[coral hornet]

this might be a bit hard to explain, but how can i generate new geometry on a mesh and cause a sort of natural flowing indent at a certain point? In my game i want certain organic substances (giant mushrooms blocking a path, trees, moss, ect) to be able to be shot and destroyed, i dont really need physics or anything, but i do need a way to make dents and eventually decimate the entirety of a meshes geometry, and im wondering the best way to go about it

ill make a quick diagram of what im trying to achieve

i want to make a simple dent in the geometry by forming and moving new geometry to sell the idea of destruction

and continually decimating the geometry to the point where it can eventually have no verts left remaining and be completely destroyed

im wondering what the best way to go about this is, as it sounds rather complex

[odd zenith]

hey how can i make a hashtable that is editable in unity properties window (public table). Or should i use a diff type of array? I want to make a list of prices, and they key needs to be a string name of an item. example of what the list would look like:

trash = 10
glass= 25
goo = 1000

[proper oyster]

you could use a array of a custom struct that then is moved to your hashtable on start

[odd zenith]

why would i need a custom struct and is there a simpler way to do it?

i want to b able to set key name and value in the unity editor

like in properties window

[proper oyster]

the inspector will not serialize / show the hashtable

unless you build a custom editor for it to display / handle it

[somber nacelle]

unity cannot serialize dictionaries (or their non-generic equivalent Hashtable). you could get around that with the advice malzbier suggested, find a custom inspector/serializer than can, or use one of the several serializable dictionary assets

[odd zenith]

is it worth it or no

this is like

a scrap project

for learning

[proper oyster]

its a cool thing to learn
if its only the utility of having it
i would probably go the work around unless i find something pre made

[dusk apex]

No, there isn't a simpler way to do what you're wanting without 3rd party inspector/serializers.

[odd zenith]

so j make prices table in script then prob

[boreal bone]

I don't know much about procedural generation but maybe marching cubes is something you could look into?

It makes it super easy to destroy/create geometry

and the mesh doesn't have to be entirely made of marching cubes, it could be that the marching cube mesh only occludes the plants and other stuff that you're doing with some shader magic

[coral hornet]

neat idea, ill look into it, thanks

[boreal bone]

Also I found this @coral hornet https://80.lv/articles/a-gun-that-melts-rocks-in-unity/

Somehow they used a combination of Shader Graph and VFX graph

so you could look into some advanced VFX graph use cases

[coral hornet]

ugh.. i hate the unity graphs.. id much rather program a shader for that, if possible

[boreal bone]

Well VFX graph doesn't really have an alternative

[coral hornet]

is VFX graph just for the lava and fire and whatnot?

[boreal bone]

I would assume so?

I don't know which would handle the actual mesh displacement tho

[coral hornet]

also, this part is important, i dont believe i can use shaders for this because i need it to physically alter the geometry and by extension the collision

[boreal bone]

hmm

that's a tough one

[coral hornet]

i can do most of the things without something like this, for example, i dont need procedural destruction to have the player shoot vines off a doorway or smth

[boreal bone]

one more resource

take a look at this vid

https://youtu.be/Cp5WWtMoeKg

specifically around 2:00

[coral hornet]

but i do need it for things like shooting chunks off a giant mushroom to get past

[boreal bone]

but it can be faked with shaders though

like the geometry itself doesn't necessarily need to be destroyed I'd imagine

[coral hornet]

for collision id assume so, shaders are so isolated that i doubt you could alter collision with a shader

[boreal bone]

That's a bad idea for collision

You don't want a mesh collider

[coral hornet]

why exactly

[boreal bone]

to handle all of that

[eager aspen]

So say im driving a 2d top down car using Add force to move it in its Up (forward direction) using AI to a waypoint, how would i check if the waypoint is more to its left or right relative to its location?

[coral hornet]

is there a way to make a custom 3d collider? perhaps i could just significantly reduce the detail of the collider with an algorithm?

[coral hornet]

id assume you would use the dot product

[boreal bone]

You could get the Vector3.Angle between the direction towards the waypoint (waypoint.position - player.position) and the player's normal

[boreal bone]

You could do that

[coral hornet]

if you have the cars forward vector, and the vector pointing from the car to the waypoint, you could get the dot product of those angles and use that as a comparison

[coral hornet]

im probably just gunna limit the shootable elements to fairly rigid gameplay

[eager aspen]

how would i interpret this? i haven't used dot products a whole lot

[coral hornet]

like shooting a tree wont make the tree fall from the exact point you shot it at, just make it fall from a set point in your direction

[coral hornet]

so basically

lets say you have a vector (0,1)

and a vector (1,0)

so one pointing straight up and one to the side

the dot product will return 0

if you have (0,1) and (0,-1)

it will return -1

i probably could explain it better visually

[boreal bone]

https://www.falstad.com/dotproduct/

[coral hornet]

when you compare the black vector to itself, you get 1, they are the exact same, when you compare it to the blue one, you get 0, its a 90 degree angle, when you compare it to the red one, you get -1, they are complete opposites

if the car is facing forward, and the point is to the exact right of it, just get the vector pointing towards it and if it returns close to or exactly 0, then it is to the right or left of the car

[boreal bone]

both vectors need to be normalized, might I add

[coral hornet]

yeah, always assume its a normalized vector in vector math, unless the distance is actually taken into account in the equation

[eager aspen]

so if it gives me 1, the waypoint is directly ahead

[coral hornet]

yes

[eager aspen]

but how would i know which it is between left and right

[coral hornet]

if it gives -1, it is directly behind

[coral hornet]

use the dot product and compare the vector pointing left from the car

if its 1, it is directly left

if its -1, it is directly right

[eager aspen]

Ahhhhhh

there we go

[boreal bone]

wait no

if it's -1 then it's behind

[coral hornet]

if the vector is forward, yes, right?

[eager aspen]

thank you i would have been circling this for forever

[coral hornet]

i was talking about if the vector is coming out of the left side of the car

if its -1 itd be right, right?

because the vector pointing left compared to the vector pointing to the waypoint is -1, meaning it is opposite directions, thus pointing right, yes?

[boreal bone]

that still doesn't make sense to me lmao

[coral hornet]

ok so

[boreal bone]

If it's to the left

A dot B is 0

[coral hornet]

assume that the black arrow is pointing out of the left side of the car

[boreal bone]

to the right

A dot B is also zero

assuming that the red is the forward

and the blue is the direction to the waypoint

[coral hornet]

im talking about if the red is left

[boreal bone]

left compared to what?

[coral hornet]

because he wants to know if his waypoint is to the left or right of the car

[boreal bone]

right

[coral hornet]

ok look

red arrow is left compared to the car

it is pointing out of the left side of the car

blue is pointing towards the waypoint, assuming the waypoint is to the right of the car

the dot product is -1, yes?

and if it is 1, it is left of the car, yes?

[boreal bone]

okay yeah that makes sense

[coral hornet]

👍

[boreal bone]

Wouldn't it be easier to calculate the Vector3.Angle(forwardDirection, waypointDirection)

[coral hornet]

ive never used vector3.angle

[boreal bone]

It does exactly what you think it does

[eager aspen]

just wanted to share got this implemented and it worked perfectly

[coral hornet]

the dot product was the first thing that came to my head

[coral hornet]

angle between vectors?

[boreal bone]

yep

[coral hornet]

👍

[eager aspen]

var dot = Vector2.Dot(-transform.right, (player.position - transform.position).normalized);
if (dot > .2f)
{
_Rigidbody.AddTorque(turnSpeed);
}
else
{
if (dot < -.2f)
{
_Rigidbody.AddTorque(-turnSpeed);
}
}

[coral hornet]

well i guess you could use either

[coral hornet]

very nice

i suppose the real difference between angle and dot is that dot gets the absolute angle (no negatives) as a float of sorts

[boreal bone]

and it's always between -1 and 1

[coral hornet]

of course if we were talking actual angle in float itd be 0,0.5,and 1

1 bieng 180 degrees, 0 bieng 0 degrees

devided by 180

absolute angle

[coral hornet]

yeah

[boreal bone]

right
