[late bobcat]

Ehy guys, i was trying to replicate vampire survivors for those who knows the game and i've a question. As you can see there's a circle around me (the one who's opacity is less). That circle should deal 30 dmg to enemies colliding with it (using ontriggerstay2d) and enemies have 30 hp. What am asking is. Enemies should get oneshot from the circle but instead, when there are many, some of them go trough, do you know why?

[zealous oxide]

slowly rotate the game object with the line renderer/laser so the second point on the line renderer lines up with the player character, but with a delay. i can do it instantaneously but im trying to get the rotation to move slowly, lag behind the player

[scarlet skiff]

i am trying to make one script that handles all the collision for the player, however, when colliding with a fireball there are two outcomes, one is that the player takes damage and the fireball is destroyed, and the other is that the foreball is reflected off the player and continues on its way.

problem is, the condition that needs to be true to reflect the fireball, is to check if the fireball has collided with the child "shield normal" of the parent player (the player has the script for collision). Problem is, this requires a OnCollisionEnter2D inside a OnCollisionEnter2D... which seems to be not possible, instead i opted to check if the fireball has collided with the shiled in the fireball script attached to the fireball itself, then if thats true, set a "isReflected" bool to true, but since im running two OnCollisionEnter2D they run at the same time and the "isReflected" bool is nit set to true on time

[slender nymph]

just check if it has collided with the shield and reflect if it has, if it has not then you check if it has collided with the player

you are way overthinking how to set this up. a simple if/else if is all you need

[teal viper]

Maybe just lerp or MoveTowards the transform.right vector?

[zealous oxide]

yeah i tried those but ultimately went with something a bit different which now works as intended. thanks for the suggestion 🙂

[pseudo frigate]

i have the following code on the inventory gameobjects, dragging them works but the initial mouse position is wrong. attached is an image of the hierarchy, theyre all under the same canvas, have tried a few different things but nothing is working, what am i doing wrong? the Holder object is the one moving around

    public void OnBeginDrag(PointerEventData eventData)
    {
        InventoryManager.Instance.draggedObjectImage.sprite = itemReferece.itemSprite;
        InventoryManager.Instance.draggedObjectRect.anchoredPosition = Input.mousePosition;
        Cursor.visible = false;
    }

    public void OnDrag(PointerEventData eventData)
    {
        InventoryManager.Instance.draggedObjectRect.anchoredPosition += eventData.delta / InventoryManager.Instance.inventoryCanvas.scaleFactor;
    }

[elder osprey]

Could I please get help with this?

[teal viper]

Are you sure you want to use the anchored position? It would be relative to the parent and anchors. While pointer position is in screen space.

[teal viper]

Debug. See if your spherecast is hitting anything and if it does, what is it.

Looks like your code is trying to access a desttyoed particle system
the error message will contain a filename and line number. Start by looking there

[harsh silo]

yeah the particle system is my muzzle flash effect, but i dont know why its getting deleted randomly

[wintry quarry]

the error message will contain a filename and line number. Start by looking there

[harsh silo]

MissingReferenceException: The object of type 'ParticleSystem' has been destroyed but you are still trying to access it.

[teal viper]

Position should follow it, assuming your canvas in in screen space.

[scarlet skiff]

but it doesnt set the isReflected bool to true in time

it gets to the else statement first, which destroys the object

[slender nymph]

Why do you need that bool?

[pseudo frigate]

its screen space - camera, its a UI camera, not the main cam

[wintry quarry]

Likely some other code you have is destroying it.

[scarlet skiff]

its set to true if the fireball has collided with the shield

[slender nymph]

Again, why do you need that bool? Just check if it is colliding with the shield there

[scarlet skiff]

you mean in this method itself?

[harsh silo]

This is my enemy health script, but I don't have it on the muzzle flash particle effect is the weird part

public class EnemyHealth : MonoBehaviour
{
    [SerializeField] float hitPoints = 100f;
    
    public void TakeDamage(float damage)
    {
       hitPoints -= damage;
       if (hitPoints <= 0)
       { 
        Destroy(gameObject); 
       }
      
    }
}

i only have that script on my enemies

[ivory bobcat]

What do you have it on instead then?

[harsh silo]

That script is on my enemies but for some reason my muzzle flash particle effect is randomly getting destroyed from it

[wintry quarry]

Here's the steps to quickly figure out the issue:

• Look at the inspector of your WeaponScript instance in the scene
• Click on the particle system reference you have assigned there
• Observe which object Unity highlights/takes you to
• Observe that object while the game is running and make sure it's not destroyed.

Also note that you may have multiple copies of WeaponScript in the scene, and this problem could be happening on one copy but not others due to how they're set up differently and which Particle Systems they are referencing

[harsh silo]

The weapon script itself doesn't have the particle system assigned, just the item that the script is on

[wintry quarry]

Wdym by this? Weapon Script has: [SerializeField] ParticleSystem muzzleFlash;. That means you must assign it to something in the inspector

[wintry quarry]

yes that's what I meant when I said "Look at the inspector of your WeaponScript instance in the scene"

the instance

not the script itself

[harsh silo]

ahh

[teal viper]

That could be the issue. If they have different resolutions, there would be weirdness.

[harsh silo]

ugh i cant even get it to trigger now

its very random when it happens vs when it doesnt

ok i triggered it, now it just says this as expected

[wintry quarry]

did you watch the obejct that used to be referring to?

Is that object now destroyed?

[harsh silo]

yes it is

[wintry quarry]

ok so

figure out why that's happening

the problem lies there

it has nothing to do with this script

[vale karma]

how can i make the camera a FPS pov? as of now the camera can turn up and down, but not left and right. The player can turn, but the cameras Y rotation doesnt change

[wintry quarry]

look up a tutorial for FPS controls, there are thousands of them

[harsh silo]

the ONLY place I have any destroy command is in the enemy health script

[vale karma]

public void OnLook(InputAction.CallbackContext context)
{
    // Reads movement input from the Mouse Input Action.
    mouseInput = context.ReadValue<Vector2>();
    Debug.Log(context);

    // Sets the y-axis input from the Mouse inverted to the camera up/down rotation.
    // Clamps up/down view to 45 degrees.
    // Multiplies the x-axis input from the Mouse and sensitivity to the players left/right rotation.
    // Rotates the first person camera local to its own rotation.
    firstPersonCameraXRotation -= mouseInput.y;
    firstPersonCameraXRotation = Mathf.Clamp(firstPersonCameraXRotation, -45f, 45f);
    firstPersonCamera.transform.localEulerAngles = Vector3.right * firstPersonCameraXRotation;
    

    // Rotates the player with the player left/right rotation every time the mouse is moved.
    playerYRotation = mouseInput.x * mouseSensitivity * Time.deltaTime;
    gameObject.transform.Rotate(0f, playerYRotation, 0f);
 
}

[wintry quarry]

show the inspector for the M4 object

[vale karma]

i know but alot of them arent working for some reason. I had this issue before but dont know how it got fixed

[wintry quarry]

you should NOT be multiplying deltaTime into that

[vale karma]

good to know lol, i still have trouble of when physics are at play idk

[wintry quarry]

if this script is on an object with a Rigidbody you should not be rotating via the transform

[vale karma]

it has a character controller with the new input system

[wintry quarry]

gameObject.transform.Rotate(0f, playerYRotation, 0f);```
should instead be:
```cs
rb.rotation *= Quaternion.Euler(0, playerYRotation, 0);```

ok scratch that then

[wintry quarry]

what trouble?

[vale karma]

using time.deltatime

[harsh silo]

ah that fixed it, ty @wintry quarry

[wintry quarry]

right, as mentioned you shouldn't be using it

[vale karma]

at all? or just for the playerYRotation?

[wintry quarry]

When handling mouse input

[vale karma]

okay

[wintry quarry]

mouse input is by its nature already framerate independent

because the values you are getting are movement since the last frame

[harsh silo]

one more question though, its also happening on my bullet impact object, but that has "Stop ACtion" set to none

[vale karma]

i took it out, now the only thing im havin an issue with is how to rotate the camera on the Y axis of itself, normally you would parent the player over the camera, but its bad habit right?

[wintry quarry]

start over looking at the error filename and line number

[ivory bobcat]

Likely something to do with

Assuming this impact object is what you're referring to

[wintry quarry]

the code looks ok on the left there

[harsh silo]

I changed it

this is what its supposed to be

and the effect works for a while then gets destroyed

this is the code in question

So looks like you're destroying hitEffect somewhere

btw make sure you're referencing the prefab

and not some instance copy you have in the scene

[wintry quarry]

because this screenshot seems to imply you have a copy in the scene for some reason

[harsh silo]

ok ill double check that

[wintry quarry]

delete any copies from the scene, and then double check the prefab itself

[queen adder]

SPRING

Im back from work

[warm anvil]

oh hey! speak of the devil, i was literally about to ask someone if they could pickup the baton question 🙂

[queen adder]

baton?

[warm anvil]

so the TLTR question was: how is this used / interpreted

InputAction action = playerInput.Actions["ActionName"]

baton, like a relay race (the metal rod passed along)

[queen adder]

From the InputAction asset

You have a list have actions

[harsh silo]

The prefab was what I had referenced

[queen adder]

You insert the action name from one of the actions from the input actions asset inside of ["ActionName"]

[warm anvil]

ah ok

[queen adder]

Jesus christ i said action alot

[warm anvil]

so Backpack in this case ofc

[queen adder]

Yes^^

playerInput.actions["Backpack"];

[ivory bobcat]

You couldn't have destroyed the prefab without acquiring other warnings about destroying assets so likely you changed the reference sometime after starting the play session.

[warm anvil]

so I think what you're stating as the next logic conclusion is that for example this code:

    private void OnEnable()
    {
        _input = new InputActions();
        _input.Humanoid.Backpack.performed += HandleBackpack;
        _input.Humanoid.Enable();
    }

    private void OnDisable()
    {
        _input.Humanoid.Backpack.performed -= HandleBackpack;
        _input.Humanoid.Disable();
    }

    public void HandleBackpack(InputAction.CallbackContext context)
    {
        if (context.performed)
        {
            Debug.Log("Attack performed");
        }
    }

[ivory bobcat]

Implies you've really referenced a prefab and not a scene object and it was destroyed

[queen adder]

Thats not how i would make it

Share the entire class please

[harsh silo]

well i have the prefab still and i re-applied it and its still happening

[warm anvil]

you can use that one line instead of possibly subscribing to an the HandleBackpack event and then having a separate method called HandleBackpack?

using UnityEngine;
using UnityEngine.InputSystem;

public class InputSystemController : MonoBehaviour
{
    private InputActions _input;

    void Awake()
    {
        PlayerInput playerInput = GetComponent<PlayerInput>();
        InputAction action = playerInput.Actions["ActionName"]
   }

    private void OnEnable()
    {
        _input = new InputActions();
        _input.Humanoid.Backpack.performed += HandleBackpack;
        _input.Humanoid.Enable();
    }

    private void OnDisable()
    {
        _input.Humanoid.Backpack.performed -= HandleBackpack;
        _input.Humanoid.Disable();
    }

    public void HandleBackpack(InputAction.CallbackContext context)
    {
        if (context.performed)
        {
            Debug.Log("Attack performed");
        }
    }
}

[ivory bobcat]

Just for clarity, prefab refers to your asset not in the scene.

[queen adder]

Does that code work?

[warm anvil]

yes

well, not anything in Awake()

but everything else yes

[queen adder]

Oh thats because i dont use InputActions like that

I didnt even know it could be that simple

Im confused by that code

[warm anvil]

well, i can't take credit but I'm thrilled I can pass along at least something 🙂

[harsh silo]

this is what winds up happening

[queen adder]

the InputActions instance knows about the BackPack action?

[warm anvil]

let me cross-check...

[harsh silo]

notice how the impact disappears after like 10 shots

[queen adder]

The console is printing Attack Perfomed?

Im not doubting you or anything im just shocked that works

[wintry quarry]

Why do you have these HITFX_VFX instances in the scene?

[warm anvil]

ik 🙂

[harsh silo]

those are the particle systems

[queen adder]

Well ok then

Did u need help with anything else

[harsh silo]

i just created an extra VFX_M4 item when troubleshooting before sending the vid

[queen adder]

Thats pretty simple thx for sharing!!

[warm anvil]

not at the moment, ty! you gave me an alternative. FYI all you need for it to work is an empty game object with that script and ofc you know an inputsystem object that's called InputActions (btw not to be confused with Unity.InputSystems's InputAction (non-plural).

[arctic ibex]

So, when i made my tilemap collider friction less (so i couldn't stick to the walls) this happened. I'm guessing it's cause the floor is so slippery, but I can't figure out how to fix it without making the walls grippy again. any ideas?

Wait, is it cause i use tranform.position to move the character instead of setting momentum?

[ivory bobcat]

Hopefully none of them were the hit effect object.. The hit effect object was supposed to be a prefab and not scene object

[arctic ibex]

so it sets its position into the wall then gets ejected?

[queen adder]

I think u have "Create a C# class" Selected for ur input action asset

[warm anvil]

if you don't mind shortcutting the test i can do, how would you execute your line of code?

InputAction action = playerInput.Actions["ActionName"]

aka how do you act upon the action

[queen adder]

You have something else going on Spring

[harsh silo]

ahhhh

[faint osprey]

ok so im trying to get my enemy to dash to the players last position with this code private IEnumerator TreeDash() { moveBool = true; playerPos = player.transform; while(true) { gameObject.transform.position = Vector3.MoveTowards(gameObject.transform.position, playerPos.position, 0.01f); yield return null; } }
ik theres no break in the while loop but for some reason when i run this it doesnt go the the location that i set at the top but it just follows the player constantly and i dont know why

[warm anvil]

no, just completing the thought/technique you shared was all

[harsh silo]

im a little slow tonight thank you all for the help

[queen adder]

You can delete my code

[warm anvil]

but doesn't it work?

[queen adder]

Its specifically for the player Input

No u have to do extra stuff for my code

I thought you were just trying to use the Player Input

[warm anvil]

oh ok, yours actually sounded VERY simple and was like, why do people do it the way I shared 🙂

[queen adder]

No urs is simpler

So good job👍

[ivory bobcat]

You're moving towards the players current position and not their last position

[warm anvil]

again, can't take credit - at least a person Fen here helped and there's seems to be a pattern of the technique from Inventory Systems on youtube and/or Unity's new Input System to show this technique

[faint osprey]

im not tho im setting it once at the top and never again

[queen adder]

Yeah Fen is way smarter than me when it comes to this stuff

[warm anvil]

have a good evenving vee, thanks for reaching to me again

[queen adder]

Ofc man you 2!

[ivory bobcat]

If you're referring to the referencing of the transform component, it's a reference and not a value copy

If you want to move to a value, cache the last known position and move towards that - not the players transform component.

[faint osprey]

thats what im doing im caching the players position once as a variable then when i start moving it towards the player if i move the player while its moving it will move towards the new player position instead even though i never set that variable again

[ivory bobcat]

You're not caching the position. You're caching the transform component.

position = player.transform.position

Where position should be a vector 3 value rather than a reference to the player transform

[faint osprey]

ah right that makes sense

its saying its not been assigned tho

[ivory bobcat]

Maybe show the error

[faint osprey]

wait no im dumb i got it

[ornate olive]

hey guys i need to add my text script but i cant seem to find a way to do that. i need to add the text to the score

[frigid sequoia]

Man I do not undertand a think of why this is working as it is working....

I want a proyectile to rotate towards the closest object with the tag enemy

If I use a separete script that just rotates a object towards another object and assing it there it works as intended, if I add that same code to this script, it doesn't

But in a really weird way

That cuve is tagged as an enemy

The botton left proyectiles seem to want to go DIRECTLY in the opposite direction

The rest just seem to straigh up ignoring

[fierce shuttle]

There are 2 types of texts in Unity by default, UnityEngine.Text which is the legacy built-in, and TMPro.TMP_Text which is the more updated text solution, it looks like you are using the latter but your type in your script is the former

[ornate olive]

can you help me fix my script

using UnityEngine;
using TMPro;

public class score : MonoBehaviour
{
public Transform player;
public TextMeshProUGUI scoreText;

// Update is called once per frame
void Update()
{
    scoreText.text = player.position.z.ToString("0");
}

}

[frigid sequoia]

What am I doing wrong?

[fierce shuttle]

And that doesnt let you drag your text mesh pro component into the slot? Also as a side note, you can use a !code block to format your code with C# highlighting

yup

You don't set it at all. So the last object position satisfying the initial range, in the found objects array would be returned.

[radiant sail]

quick question, can anybody tell me how to make the players speed stay the same when holding down W & A/D because if i move diagonally it makes the player move faster

void Update()
    {
        isGrounded = Physics.CheckSphere(groundCheck.position, groundDistance, groundMask);

        if(isGrounded && velocity.y < 0)
        {
            velocity.y = -2f;
        }

        float x = Input.GetAxis("Horizontal");
        float z = Input.GetAxis("Vertical");

        Vector3 move = transform.right * x + transform.forward * z;

        controller.Move(move * speed * Time.deltaTime);
        if(!isGrounded && velocity.y < 250)
        {
            velocity.y += gravity * Time.deltaTime;
        }
        controller.Move(velocity * Time.deltaTime);
    }```

[teal viper]

Use a normalized input vector in your movement calculation.

[radiant sail]

k thx

Is there any easy way to make the floor more solid? I'm using a tilemap collider and i keep clipping through the floor when I'm falling to fast

[rotund hull]

how can i have a button on the script in the enspector

[rich adder]

Custom inspector

[rotund hull]

no like in code you write something and when you go back into unity you see a button on the script component

what is that called

[ripe shard]

Custom inspector

[rich adder]

https://learn.unity.com/tutorial/editor-scripting

[rotund hull]

that is not it

[teal viper]

Not really a coding question. If you're using a rigidbody for your controller, set it to continuous collision detection.

[ripe shard]

But what you probably want is an attribute [Button] from https://github.com/dbrizov/NaughtyAttributes

[arctic ibex]

Oh okay

thanks

and i just realised I forgto the curly brackets, but it still says it so

[north kiln]

generally when you see an error like this you should look at the statement that preceeds it and think about whether it makes sense

[summer stump]

Curly braces were not the issue
They are not required when inline

[north kiln]

In this case, this is not how you write an else statement

[faint osprey]

how would i go about making it so my GameObject ignores colliders on other instantiated clones of that GameObject ive tried this but it doesnt work Physics2D.IgnoreCollision(wallCollider, wallCollider);

[ripe shard]

Put them on a layer and disable collisions on that layer

[arctic ibex]

yeah, I've just stared at it for a bit longer and realised I did it completely wrong lol. It's cause i origanlaly had the code written at void start, not in an if statement, and just completely forgot how they worked when i put it in one lol. Sorry for bothering you guys

[cosmic dagger]

use the collision layer matrix to place that GameObject or prefab on a layer that doesn't collide with itself . . .

[faint osprey]

can i do it with tags so it ignores everything with a certain tag

[ripe shard]

Use layers

[cosmic dagger]

no, use layers . . .

[rich adder]

But that’s a custom attribute no?

[faint osprey]

so would this work Physics2D.IgnoreLayerCollision(7, 7);

if all the objects i dont wanna collide with are on 7

[ripe shard]

Use the matrix in project settings, but otherwise it should work, yes

[rich adder]

Use name to layer

https://docs.unity3d.com/ScriptReference/LayerMask.NameToLayer.html

A bit cleaner than magic numbers

[cosmic dagger]

no, again, use the collision layer matrix to setup your layers and choose which should or shouldn't collide with each other . . .

[ripe shard]

Using named layers in code is terrible

[soft wren]

Is anyone able to help me out with a duck problem?

[rich adder]

Better than ints

If you change later the whole thing breaks

[ripe shard]

No

strings break, integers don’t

[rich adder]

U can use constant for that tho

[ripe shard]

Magic numbers are not fixed by turing them into strings, you put them in a variable/constant

[faint osprey]

if i have two colliders on an object is their a way to ignore collision on just one of them

[rich adder]

What are you trying to do with exactly

[cosmic dagger]

or use an SO with a LayerMask field and reference that. forget about strings or ints . . .

[rich adder]

LayerMask doesn’t work on gameobject int no? @cosmic dagger

[frigid sequoia]

Ok, yeah, it doesn't matter, it does the same

[rich adder]

Since that’s one layer and not multiple like LayerMask

[frigid sequoia]

Like it was the only enemy tag in scene anyways

[cosmic dagger]

GameObject int? clarify . . .

[rich adder]

Yea

gameObject.Layer

[cosmic dagger]

oh, you mean the int that gameObject.layer represents?

nope. you have to convert it to a LayerMask. i use extension methods for that . . .

[rich adder]

Yes I recall I couldn’t use LayerMask with that and had to use LayerMask.NameToLayer to get it working

[rich adder]

Surprised we don’t have that, how would one convert that into LayerMask and vice versa?

[summer stump]

Would something like 1 << gameObject.layer work?

For the one direction only of course

[rich adder]

Interesing. haven’t dabbled into bitshift myself

[shell sorrel]

the bitshift should work for it

[soft wren]

transform.rotation = Quaternion.FromToRotation(transform.up, collision.contacts[0].normal);
I have this here which rotates an enemy along the normal of the wall it hits. How would I offset the rotation so it rotates 45 degrees away from the wall and not 90?

[cosmic dagger]

@summer stump yep, using 1 << gameObject.layer will convert it to a bitmask . . .

[rich adder]

Nice! Thanks guys

[cosmic dagger]

typically, i use a CompareLayer or ContainsLayer extension method to check if two layer masks are the same or if a layer mask is contained within another . . .

[shell sorrel]

once you do bitwise stuff enough you eventually remember what it all does

[arctic ibex]

This doesn't seem to be working for some reason and I can't figure it out. What is the blaringly obvious error that I'm certain I've made?
(Also, any suggestions on how to find solutions through google? I keep trying to go to google for help, but I always end up not getting any helpful information)

[summer stump]

What, specifically, is not working?

[arctic ibex]

When i trigger OnCollisionEnter, the bool insideagain on the gate object stays the same instead of switching to false

[cosmic dagger]

you should explain what you're attempting to do and the result you want . . .

[summer stump]

Are you sure the OnCollisionEnter meesage is sent?

[cosmic dagger]

your code uses OnTriggerEnter2D. that is completely different from OnCollisionEnter . . .

[arctic ibex]

Yes, because the sorting layer switches fine

[summer stump]

Also, I see- ah yeah, what Random said

[arctic ibex]

Og yeah i meant to say trigger not collision sorry

[cosmic dagger]

one is a trigger, the other is a collision. one is 2d, the other is 3d . . .

details matter . . .

[summer stump]

Do you get any runtime errors? Like a NullReferenceException on gate?

[arctic ibex]

nope

[cosmic dagger]

place a log outside of the tag check and inside of the tag check to make sure the trigger method is called, and that the tag check is true . . .

[summer stump]

Show the whole gate !code

I suspect honestly that the bool DOES change, it just flips back immediately because of something else

My code is really bad, just warning you

[thorn holly]

Is it bad practice to put multiple classes in one script? Like for an FSM?

[vale karma]

would you guys recommend using a character controller or rigid body?

[arctic ibex]

Both the debugs worked

[cosmic dagger]

you can only do that with c# classes, not classes derived from MonoBehaviour. i'd get used to separating them unless they concrete types created from a generic base class with just the class definition . . .

[shell sorrel]

its fine, as long as you do not have multiple MonoBehaviours or ScriptableObjects in 1 file

[cosmic dagger]

to broad. it depends on the game and the type of movement you want . . .

[thorn holly]

Can I have one MonoBehavior and the rest non MonoBehaviors?

[cosmic dagger]

show us the code used for the debugs . . .

[vale karma]

well its gonna be kind of realistic movement, basic walk run and jump

the problem is i dont know how to implement gravity into my character controller :/

[arctic ibex]

Wait nvm Aethenosity was right

I set the wrong bool

[shell sorrel]

yes that is fine

[thorn holly]

Yeah it’s for an fsm, so I feel like multiple scripts is pretty uneccessary since the classes are so closely intertwined

[thorn holly]

Sweet thx

[vale karma]

is it possible to still use a rigidbody or is that bad practice?

[shell sorrel]

yeah i often have a bunch of types defined in 1 file, if they are like data containers and stuff related to the main one

[thorn holly]

Neither is bad practice, it really depends on what you want from your movement.

[vale karma]

im not picky lol, i just dont know how to get gravity to work

[thorn holly]

Rigidbody gives more freedom, while character controller is easier configurable

[shell sorrel]

@thorn holly the ones to be weary of is anything that needs a guid, since to get that it needs a meta file. So everything that derives from UnityEngine.Object

[vale karma]

yea ive noticed. but it feels like any coding with the controller is confusing bc idk how it uses .isGrounded in the characterController

multiple reasons.. also, i should probably learn rigidbodies in the longterm

[thorn holly]

Alr yeah, I’m just using an abstract class and then some states derived from it, so there shouldn’t be too much issue

[shell sorrel]

yeah 100% fine

[teal viper]

The only other issue is that you're doing lerp wrong.

[frigid sequoia]

What? Why?

[teal viper]

Because t/time is supposed to increase from 0 to 1 over time. That's the whole point of lerping.

And both parameters need to stay constant.

[frigid sequoia]

It works literally perfect when used in stand alone

[shell sorrel]

its not working how you think though

[frigid sequoia]

Like it smoothly interpolates between a and b based on the given speed

[shell sorrel]

its working likly because you are also feeding current position into the first arg not start position

lerp is not meant to move things at a given speed

[winter prawn]

Isn’t there a look towards or look at method?

[shell sorrel]

a few ways depend on if you want to apply it right away, or simply want the rotation that would make it look at something

[frigid sequoia]

THEN WHY THE HELL IS THIS WORKING?

I don't get it

[shell sorrel]

lerp(a, b, t) returns a value between a and b base on where t is between 0 and 1

[summer stump]

It's kind of working because you're doing TWO things wrong and they are kinda counteracting each other. But it's done wrong and you just havent hit the point that it fails yet

[shell sorrel]

because you are feeding the current value into a every update you are moving towards it by what you passed to t

so if t was 0.5 it gives half way closer each update

but never reaches its final target because its always by half

normally people save there start pos pass it to a, pass destination to b, then start t at 0 and add deltaTime * a multiplier every frame

Hey I think I am running into an instantiation issue, I currently have a set of abilities that from within a list that can be interchagably swapped out on the fly. but none of the abilities can even instantiate or are returning null. Is this because of a parenting issue? Currently the script will is sitting on the parent of the child it's instantiating. I don't really know if this is a beginner or higher question

[shell sorrel]

why is it called AbilityPrefab but you are passing in a refernce to the GOW Parent GO

[wispy karma]

Because the way I orignally had it set up, was to just pass in the entire prefab but wouldn't that cause circular instantiation and just not work or break the game?

[shell sorrel]

code never shows what calls Activate, so can not see what prefab is being passed to Instantiate

[wispy karma]

One sec

[shell sorrel]

also no parent is being set, so they will be created in root of your active scene, which could be fine depend on what you want

[wispy karma]

https://codeshare.io/deYZdZ

The system itself is a little complicated and out of my personal scope, but I was tasked with creating an system which will store player abilities that can be swapped out in between bosses once unlocked, which in turn has to be able to swap out all icons, prefabs etc.

Anything that you could be interested in is in the codeshare, if you need any further clarification let me know, I appreciate you checking it out

[shell sorrel]

well it looks like the first issue i pointed out

where that code calls Activate, it passes in ability.AbilityPrefab, which does not point back to a prefab based on your inspector

but the GOW Parent object

[wispy karma]

So it was originally set up like this

But the problem that creates is circular instantiation no?

Because the script is attached to the object it's trying to instantiate

[frigid sequoia]

Is only one here, the other was not relevant whatsoever and is not even part of the standalone script

But honestly this is working so good that I cannot believe it is wrong

[summer stump]

There are two things wrong with that one line of code.
You don't have to believe it, it objectively is wrong.
But if it's good enough for you in its flawed state, that is perfectly fine

[cunning rapids]

Btw, instantiating an object means "creating an instance"

C# is an object-oriented programming langauge

[wispy karma]

Each time it fires the ability it creates a single instance of the bullet so that would be instantiation no?

[cunning rapids]

I don't know the context of the issue here enough

I just got here

Can you explain the problem quickly again?

[rich adder]

recursive you mean

[wispy karma]

TLDR: My abilities are not instantiating, here is the og post

[wispy karma]

here is the codeshare

[wispy karma]

yes that's the word thank you

Totally forgot to change the mic and disable the camera on obs my bad

I don't think it's an inspector issue

[cunning rapids]

Are you sure you have the Action "AbilityThree"

Wait

Here

This is how that error message pops us

Ability is null

Check your inspector

Did you assign everything correctly?

[frigid sequoia]

Then how am I supposed to a Slerp that has to update each frame? Like if it is in the Update method, it would have to either wait to finish a slerp to start a new one or do various simultaneusly or start a new one each frame, none of those actually works

[cunning rapids]

Hmm that's weird

[wispy karma]

should be

[nimble apex]

background story: this is a system , or an UI to display game result

im optimizing a 20 lines code inside that UI, quite a lot to do, let starts with step 1

foreach (object gameInfo in history.gameInfo)
{
  gameResult.type = JsonConvert.DeserializeObject<Info>(JsonConvert.SerializeObject(gameInfo))
  //something more
}```

the game result UI receive data from server and populate itself, the model class that receives data will be used by many other classes, im told to not modify it, or the whole system will collapse

[wispy karma]

ikr?

[nimble apex]

so, without modify the base model, is this good?

[cunning rapids]

I'm unfamiliar with Activate()

[wispy karma]

I debugged and everything

[cunning rapids]

It looks good to me but I'm too sleep deprived to thoroughly check everything 😭

Some people should be able to help here

[nimble apex]

YOU NEED SLEEP

COMFY BED NOW

[wispy karma]

Activate is just a method I created for the interface

using System;
using System.Collections;
using UnityEngine;

public interface IAbility
{
    event Action<float, float> OnCooldownChanged;
    string AbilityName { get; }
    float Cooldown { get; }
    bool CanUse { get; set; }
    GameObject ForegroundIcon { get; }
    GameObject BackgroundIcon { get; }
    GameObject AbilityPrefab { get; } // Prefab for the ability
    float AbilityForce { get; } // Force to be used with the ability

    void Activate(Transform firePoint, GameObject prefab, float force);
    IEnumerator CooldownRoutine();
}```

[summer stump]

Why even use slerp in that situation? Seems like you should just use a different method

[wispy karma]

It's not a unity thing

[frigid sequoia]

How else do I calculate the positions in between 2 quaternions?

Like, vectors, I could do, quaternions, no idea

[wispy karma]

Should I maybe put this question in a higher channel? or would this still be considered a beginner question?

[teal viper]

There's RotateTowards if you want to use quaternions, and there are other methods, like SmoothDamp and such in Mathf if you want to manipulate the angle I. Some other way.

[teal viper]

Maybe start a thread, because for other people to help they'll need to scroll kilometers up the message history.
Provide all the details on the issue and your code.

[low path]

Are you sure the problem is not with your “canUse” variable? The message you showed happens after you necessarily call get equipped ability which will give a specific message if it returns null, but this doesn’t happen. Either the manager returns null from its collection or you aren’t returning null and “canUse” is false.

[wispy karma]

Yeah I just figured it out

It totally was the canuse variable

Thank you all for your help

I really appreciate it

I'll hop on back if it's not the case

[obsidian fern]

I'm trying to make a tank shell projectile that ricochets if it hits the object at too steep of an angle.

I had it figured out at first:

• Sphere collider at the tip and explodes on impact.
• and a Cylinder collider in the shape of a hockey puck right underneath. If the projectile touched the target with this first then, ricochet.

Problem is: it moves too fast so it sometimes phases through walls. I fixed this by making the sphere colliders height really large so it shoots ahead of the projectile reaching far.

But now how do implement the ricochet mechanic

[cosmic dagger]

try using the Vector3.Reflect method . . .

[obsidian fern]

I'll have a look

[vale karma]

is it more expensive to call the return method IsGrounded(); that includes raycasts every time it needs to be checked, or if I just put IsGrounded(); in update and change it to a void method?

because i wanted to only use it when i need to, I guess for better (clearly not noticable) optimization, but i realize if my movement method calls the IsGrounded method and my movement method is in the Update method, then Id just be calling it multiple times + the update function

[faint sluice]

From "speed" standpoint doesn't even matter, but I would argue doing it with return is better

You're creating a function who's single purpose is to check if it's grounded and can be reused anywhere else

[vale karma]

yea i figured as well, then i thought if i just use IsGrounded in update and set it as a bool variable, maybe it would cost less?

Its really a point of do i want IsGrounded in the Update function lol, keeping things tidy

[faint sluice]

Depends on how often do you want to see if you're grounded or not

For most of my games

void Update()
{
If(isGrounded())
{
DoMovement();
}
}

Is pretty clean and tidy

Just make sure you're checking "isGrounded" only once per frame at Max

[vale karma]

then id probably want it in update. thats wat i was gettin to, if i have to check 4 different times at once it could be an issue

[charred spoke]

4 different if statements in a single Update wont even make a dent in the most basic of cpu’s

[vale karma]

ill just call the method in update once, and get the data from the variable

Yea but im trying to make a fps controller I can use in other games ill make, they have one on the asset store but i dont quite understand it, also it doesnt use the new input system

I want to make it look nice and be politically correct lol

[faint sluice]

He means 4 different is grounded check in single frame i think lol

[charred spoke]

Still

[vale karma]

I was using the new input system and a character controller, then realized the controller isnt that flexable

so i had to switch to rigidbodies, ive been working on a system all day lol

[faint sluice]

Even if it doesn't make dent it's good coding practice

[charred spoke]

I mean what he is doing now is better in terms of code clarity and maintainability and even technically performance. Im just saying that modern cpus are truly insanely and disgustingly fast.

It helps to know that

[vale karma]

I work at a pc shop during the day, and let me tell you pcs are becoming the value of a car

[frigid sequoia]

I did change it, it works exactly the same, is indistinguiseable

It is still resulting in the same issue

[arctic ibex]

So I have all objects that reference the player do so by finding an boject with the tag "Player" at the start, and even though the player was technically not already in the scene and was being instantiated, it worked perfecty fin with no issues. But now it's just started not working. For some reason the object reference never works unless i put it in update or something. Is there way to fix this? Because it was working fine before. Technically teh new way (putting it in update) works fine but it just felels clunky and I'm sure theres a better way to do it.

[vale karma]

do i still need to add .normalized to the moveDirection if i am using the new input system?

[rich adder]

"never works"

wdym

do you get error ? show error

if you think they somehow were able to find the player before instantiation you remember wrong lol

[faint sluice]

You're saying player is instantiated later on? So I'm assuming either in a "start" method or later, so ofcourse it can't find a object with tag "player"

[arctic ibex]

The player is instantiated in start

[rich adder]

and line 23 in rope ladder is Start() ?

[teal viper]

Then maybe share more details on the issue. Because it was not very clear and I don't see any obvious issues in the code. Perhaps it's the setup in the scene..?

[rich adder]

if player is spawned in start ofc its not gonna find it

[faint sluice]

It's cuz you're assigning value of player on start, when it's not even instantiated yet

[rich adder]

they both run start

[arctic ibex]

Yeah but it was working perfectly fine before, with no issues

[rich adder]

use awake

[arctic ibex]

even though they were both on start

[rich adder]

scripts order aren't guaranteed , between diff starts

[arctic ibex]

For the player spawner or things referenceing the player

[faint sluice]

Because execution order of same rank is finicky, you can never rely on which start will be executed first

Sometimes player was instantiated first and assigned later, sometimes vice versa

[charred spoke]

Sheer luck that the Start spawning the player was running before the other start. Did you add more scripts in the meantime?

[arctic ibex]

yeah

[rich adder]

instantiation

[arctic ibex]

Okay

[rich adder]

why is player not in the scene already anyway lol

[charred spoke]

Well you adding more scripts shuffled the execution order

So either manually set execution order or certain scripts or redo when you spawn the player

[arctic ibex]

cause they spawn in a different spot depending on where you enter from?

[rich adder]

ever heard of teleport 😛

[arctic ibex]

no

[frigid sequoia]

Basically all these proyectiles are aimed towards the cube (and they just move constantly forward), which is an object they should rotate towards when getting close, making it easier to hit; the expected in this case is literally nothing hgappens, cuase they are already looking towards the cube. The cube is the ONLY thing tagged as a valid autoaim target right now.

Instead this happens

I don't even know what they are trying to target

[rich adder]

ohh , I mean the player can already be in the scene and just be assigned a new position..

[arctic ibex]

how?

[frigid sequoia]

Is like they are snapping to one of the corners? Idk

[rich adder]

use the position you plug into Instantiate , just do playerPos.transform = newPos

for example

[arctic ibex]

ight, thanks

[teal viper]

Can you draw a debug ray at the position they're targeting?

[wintry quarry]

Just read the mouse input in update instead of polling

[faint sluice]

1. is trigger set to any clip in animator?
2. is the length of the clip long enough to be noticed?

[wintry quarry]

Otherwise you need to actually rotate in the event function or consume the input when you use it

I.e. set view to V2.zero at the end of Update

[vale karma]

okay, how can i read the mouse input in update while still using the new input system?

[arctic ibex]

Yes and, it's about a second and a half, with no loop (so hopefully it should stay on the last frame)

[wintry quarry]

It will be simpler just to do the latter thing

view = Vector2.zero;``` at the end of Update

[faint sluice]

Mind showing animator window?

[arctic ibex]

course not

huh, for some reason the preview doesn't show th eanimation

BUt the animation window does

[faint sluice]

No clue then, maybe #🏃┃animation will be able to help better

[arctic ibex]

oh, i didn't even know that was there

thanks!

[frigid sequoia]

Is just something like this un update right? Debug.DrawRay(transform.position, transform.forward, Color.red, 0.1f);

Cause it is not showing, should it?

[wintry quarry]

Did you enable gizmos?

[frigid sequoia]

I did dissable a lot of them, but not sure which is the one that shows that

[teal viper]

Cast a ray in your LookAtTarget method with the origin being the target position and an up direction, so that it makes more sense.

[wintry quarry]

It's just the overall on/off toggle for gizmos that governs Debug.DrawRay

[frigid sequoia]

Doesn't seem to show

That should show, right?

[teal viper]

#💻┃code-beginner message

Also make the radius bigger, like 5f or something

[frigid sequoia]

Mmmmm, what?

[vale karma]

the IsGrounded Raycast check is flickering on and off. if i stand still a certain way i can get it to turn off and on without jumping. what is causing this? https://paste.ofcode.org/aiSicvmiSYLM7AVYkwDMSC

[rich adder]

0.5f + 0.2f

just write 0.7f lol

[vale karma]

lol thats multiplicaton then addition right?

i dont like it either, i jus followed a tutorial

[frigid sequoia]

So that's a ray FROM the target towards the position of the proeyctile?

How?

[rich adder]

also where is transform .position

and how big is the player, show debug.drawray

[frigid sequoia]

Like why all of them aiming the right side???!!

[vale karma]

player is a 2m capsule

[teal viper]

Use Vector3.up for the second parameter...

[vale karma]

wym transform.position?

[rich adder]

when does it turn off and on

[rich adder]

the pivot

center?

or feet

[vale karma]

ohhhh you know what

it probably is because the center isnt at 1m, its at 0 bc i put the components on an empty parent over the model

let me try it out

[rich adder]

okay, though personally I would use a bigger shape for like edges, I usually use ray for slope angles n stuff

[vale karma]

what should i use? im still learnin, if theres a better method im down, im already not liking the setup i made. the camera controls the mouse and sensitivity, while the player controls movement, its a bit weird

[frigid sequoia]

Nope, that's not showing

Why?

[rich adder]

if the player is a capsule I usually go with a sphere since that fits perfectly the bottom part

[teal viper]

It does. It's just small. Which is why I told you to make it 5 units.

[vale karma]

oh god there are many more parameters needed with a sphere hehe

[rich adder]

    private Collider[] groundedResults = new Collider[3];
 private bool Grounded()
 {
     int hits = Physics.OverlapSphereNonAlloc(transform.position + groundedOffset, cc.radius, groundedResults, groundedLayers);
     return hits > 0;
 }``` not really lol

[ivory bobcat]

return hits > 0

[rich adder]

true idk why when I recorded the video with that way !

[frigid sequoia]

Now there is line aiming upwards in the cube, that's.... expeceted, why sending the ray up?

[vale karma]

yea that looks simple to understand, just alot of new information. I havent even gotten to making the game yet

[rich adder]

Dont worry about making a whole game yet in the beginning tbh

just play around with the engine

get familiar with components and how they works, scripts etc

[teal viper]

To make sure that the target position is correct.

[teal viper]

Do you actually seem the rotating? Are they still rotating during the time of the screenshot?

[frigid sequoia]

They are rotating

Like in fact....

[vale karma]

ive already made a couple platformers from start to finish, and dabbled with menus and stuff, I am getting the hang of alot of it without needing to copy code completely. So right now im trying to wrap my head around the correct way to do things, even if its not needed as a beginner. Id rather make sound games with not alot of content than a broken game from youtube tutorials

[frigid sequoia]

From their position TO the target the rayscast is this

That's what they are looking towards

But why though?

[rich adder]

initially as long as it works, thats "the correct way"

[teal viper]

Share the updated code(the debug line specifically)

[rich adder]

you're in the beginning phases you're just meant to make stuff happen, there are hundreds of ways to do the same thing in dev

[vale karma]

i feel like im learning wrong through half the tutorials i watch, theyre all sort of destructive

[frigid sequoia]

https://gdl.space/rurohayogi.cs

Isn't much different

[rich adder]

yeah tutorial hell. You kinda have to start researching stuff and paving your own ways

[frigid sequoia]

Oh, I know why, is cause I am using a Vector3 instead of a transform rigth?

[teal viper]

Try debugging the object name of the returned position.

[frigid sequoia]

Unity doesn't like that

[teal viper]

What? Why would that be related?

[vale karma]

what is cc.radius in the code?

[teal viper]

Where are you planning to use the transform anyway?

[frigid sequoia]

Cause the issue comes from when passing the target possition to the LookAtTarget, and I am pretty sure about that

[rich adder]

cc would be the CharacterController

[vale karma]

this is golden, ever since ive been reading docs first, trying, then watching a video ive noticed major improvements

@rich adder i dont have a character controller anymore :/ i gave it up for rigidbody

[rich adder]

then use CapsuleCollider, they're both capsules

[teal viper]

How would passing the transform change anything?

[vale karma]

This method worked, woohooo

[frigid sequoia]

Dunno, but this makes 0 sense to me man

Is returning using the correct positions in the debug, like those are the exact coordinates of the cube, but then is trying to look at that angle which is clearly not rotatingTowards the target

[ebon robin]

try some top down

or 2.5d games

[vale karma]

ive tried my hand at it, im not ready to get into tilemap optimization yet, and i want to freeroam, so im doin 3d for now

[teal viper]

Ooof. Okay. I see the issue now. Please check the documentation of Quaternion.LookRotation. you're not using it correctly.

[frigid sequoia]

I have read it, I didn't understand shit

I curse the quaternions

Like why do we need them having Euler?

[teal viper]

To avoid gimbal lock and other nasty issues.

If you don't like quaternions, why not just set the object transform.forward instead..?

[frigid sequoia]

Use what? Isn't that just the vector comming form the front of an object? How do I apply rotations with that?

[teal viper]

You can set it and unity would rotate the object accordingly.

[frigid sequoia]

Set it to what?

[teal viper]

To the direction you want it to face.
*To the desired forward direction.

[vale karma]

how can i smoothdamp the camera movement?

im guessing using Addforce is causing the camera to stutter or update weird

[native seal]

What are the use cases for a singleton over a static class? Which should my save system be?

[night mural]

A static class is basically a freely read/writable global. Globals are generally bad, because they can be written from anywhere and therefore are easy to make mistakes with which are confusing to track down, and because they make it harder to test parts of your code in isolation.

A singleton is preferable because it's at least an instance, so in theory you could build another 'instance' of your game which includes its own version of that singleton, or you could make an instance of it for testing which isn't global. In practice though, most singleton implementations I've seen intentionally prevent these advantages and are globally accessible through a static reference, in which case I'm not sure there's much of an advantage.

Ideally you would compose your game out of non-global pieces which you can freely have multiple of in whatever context you need. If your game requires a single instance of a specific service you'll want to handle that properly, but that's different than how I see a singleton usually used where the code depends on there being a single instance of some global thing

[native seal]

well the things that would make sense to have a "global" for is my item database and save system

would it be preferrable to use a singleton instance or just a static class

[teal viper]

You'd use rigidbody interpolation to avoid jitter

[native seal]

right now im using a static class and its working fine, but is that the best choice?

will I run into problems down the line

[night mural]

if it's working fine for you i woudln't worry about it

maybe, but you can't pre-empt every problem and you shouldn't try

one good reason to avoid statics is if you want to turn off domain reloading, which can help you iterate faster

but you could also use them and just handle that yourself

[native seal]

what do you mean?

[night mural]

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

[native seal]

oh, so just an editor thing

wont effect the game

[night mural]

it might help you make the game more quickly, which affects it in that it needs to be made to exist

[native seal]

lol true

[night mural]

not existing is the biggest problem most games have

[vale karma]

I have it on interpolation already, i posted the issue in #🖱️┃input-system

[native seal]

so turning it off only effects static fields

everything else will reset properly

since it will technically leave scope

[frigid sequoia]

And how do I get the desired position and set an angle in between?

That just seems like the slerp I was doing at the beggining

[night mural]

right, so you have to reset your statics yourself if you want to use them with domain reloading turned off (if you avoid statics you never have to think about/remember that)

[native seal]

im only really using static methods

[frigid sequoia]

Man, this is literally just, looking at a specific target with a transition, it can be that difficult, like wtf, I am tired of this issue

[night mural]

oh, static methods are great and you should use them as much as you'd like

[native seal]

and one static hashset for my item database which doesnt need to be reset anyway

[frigid sequoia]

Danm you quaternions

[night mural]

pure* static methods i should say

yeah it sounds like you do have some static data

[grave forge]

guys help pls i need help so bad

[native seal]

yes only the item database

[night mural]

but also it sounds like data which is reasonable enough to have be global, so have at it

[native seal]

aight thanks for the tips

[night mural]

yeah. I would instance that (maybe as an SO) so that if i wanted to, i could have multiple item databases and swap those in for testing or whatever but it's not a big deal

[native seal]

yes its an SO

already

[grave forge]

tf is "assets\pickle.cs(7,12): error CS0246: The type or namespace name 'Rigidbody2d' could not be found (are you missing a using directive or an assembly reference?)"

[native seal]

cause i was planning on doing that

but havent had the need to make multiple databases yet

[night mural]

sounds good to me, i'd keep it until you run into a real problem

[rare basin]

show the code

[night mural]

are you missing the using statement? have your IDE fix the error for you

[rare basin]

using statement for rb2d?

[grave forge]

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class pickle : MonoBehaviour

// Start is called before the first frame update
void Start()

}

}

[rare basin]

you cannot name your variable

the same as the type name

[grave forge]

ik

but even if i remove that

[night mural]

yes, it's not a native type. but they have it so that's not the issue

[rare basin]

well you can but

don't do it

[grave forge]

it still persesting

[rare basin]

remove that line, save it

go back to unity, what does the console says

[grave forge]

i removed it

[rare basin]

Rigidbody2D is a component that's coming from using UnityEngine

[grave forge]

Assets\pickle.cs(7,35): error CS1002: ; expected

[night mural]

...that's not what i said?

[rare basin]

anyway you were missing a ; here

[grave forge]

hey it worked

wow

im putting u in credits

[teal viper]

You'd rotate a direction vector from current to the target forward rotation. Almost same as now, but without quaternions involved.
And btw, your current issue is not caused by quaternions, but by not understand the difference between a direction vector and position vector.

[frigid sequoia]

No, I do, understand the difference, the issue comes when I want to tell it to basically just lerp its current rotation and a rotation at which is looking at something and decides that even though I give it a position to look at, the quaternions tell it that I was actually refering to a way different position in the distance

[frigid sequoia]

Also, they are both vectors, the position vector is basically a direction vector, which tells in which direction you should move from the origin to get to that position

[native seal]

so for my save system, i want it to loop through all things that implement the interface "ISavable." when the game starts. what would be the best way to do that? should I just make a public list and add them all manually?

or make the save system a singleton and use an event

[teal viper]

That's the issue. You are not supposed to give it a position to look it, but a direction.

[vale karma]

could i add a rigidbody to the camera 😮

[charred spoke]

You could

[frigid sequoia]

That's what LookAt is meant to do

[teal viper]

Indeed. Any vector can be both. The question is in relation to what object or reference point.

[frigid sequoia]

Like isn't that literally its purpose?

[vale karma]

idk why this pov is so jittery when i move, i never had this before

[teal viper]

Rotation is relative to the object, not to the world origin.

[teal viper]

If you use it properly, yes.

[charred spoke]

ISavable should provide some sort of method to register itself to the save service

[teal viper]

It creates a quaternion rotation from a direction vector.

That's it's purpose.

[native seal]

ah so on awake it registers itself

[charred spoke]

Sure thats one way

[native seal]

is that what you would recommend

[grave forge]

how do i go back to original text cursor?

[frigid sequoia]

Okey, now I just want to lerp the current quaternion rotation TO the quaternion ratation of lookAt, but it isn't working

[rare basin]

press insert

[grave forge]

thx m8

[teal viper]

What doesn't work?

[frigid sequoia]

The lookAt is returning a random position in the distance

[teal viper]

No it doesn't.

1. It doesn't return a position at all. It returns quaternion representing rotation.
2. You're not using it correctly as I said previously.
   Check the documentation of what parameters it takes.

[charred spoke]

I would not implement ISaveable on a monobehaviour. A simple class that can ne easily serialized and just holds data will do. It can register itslef in its constructor that way it cant be missed.

[native seal]

I am using it on scriptable objects, not a mb

[frigid sequoia]

1. I am refering to a random position at which they are looking at, it is actually a rotation, but they all are all aiming at the same Position in the distance, is not like each one is changing it rotation locally
2. I am using it correctly, I have literally copied the documentation and replaced the values, it is still pointing there after the changes

[verbal dome]

Show your current code?

[teal viper]

1. This is because you're using the debug ray incorrectly as well. If you use Debug.Line instead you'll see that it is correct.
2. What you have is totally not the same as the docs:
   Your code:

Quaternion lookAt = Quaternion.LookRotation(targetPosition);

Notice that targetPosition is an actual position, not a direction.

Docs code:

        Vector3 relativePos = target.position - transform.position;

        // the second argument, upwards, defaults to Vector3.up
        Quaternion rotation = Quaternion.LookRotation(relativePos, Vector3.up);
        transform.rotation = rotation;

Notice how relativePos is a direction, not a position.

Maybe you should spend some time trying to understand what I'm saying and/or read through the docs and try to understand them, instead of blaming unity, quaternions and the rest of the world, trying to prove that your code is correct.

[frigid sequoia]

I know my code is wrong, I want to know WHY is wrong, just you are wrong is no help, I already know I am, that's why it is not working and why I am asking

[teal viper]

I said like 3 times by now: position and direction are different things!

Does that make sense?

[frigid sequoia]

It does, I have done this, I have change it, it is STILL doing the exact same thing

As if I changed nothing

[teal viper]

Show the updated code.

[frigid sequoia]

Hold up, I am afk rn, went to take a snack

[vale karma]

why is it taking unity longer and longer to click play or load?

[night mural]

The bigger your project, the longer it takes unity to compile and reset everything. You can turn off domain reloading to speed things up if your code is properly architected

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

[vale karma]

i just reloaded unity to free some ram, ive been working on this for about 10 hours straight lol

[night mural]

yeah it's good to restart unity every once in a while too

[vale karma]

i cant seem to find out where the mouse jitter comes from. I even commented out the new input system and used the old input system to see if it fixes the laggy issue but its not goin away

[teal viper]

You'd need to share some code.

[vale karma]

https://paste.ofcode.org/38JcRCndP8SFjPMyrf6ddbT

so when i move the player, no jitter, when i jump and move the player, no jitter, when i move the mouse, no jitter, when i move the mouse and move the player, jitter

[teal viper]

I think rb.rotation = Quaternion.Euler(0, yRotation, 0); breaks interpolation.

[vale karma]

i thought so too, i changed it from gameObject.transform.rotation to rb.rotation , what can i do to fix that?

[teal viper]

Angular velocity or torque.

MoveRotation might be fine too

[vale karma]

i used a character controller the first time setting this up, so i guess i never saw this issue, idk how to use torque or angular velocity,doesnt MoveRotation use character controller?

[teal viper]

No. It's a method of an rb

Check the documentation

[vale karma]

i wish i didnt have work today, i could sit here for hours learnin about this stuff

[vale karma]

okay so Unity docs say "If Rigidbody interpolation is enabled on the Rigidbody, calling Rigidbody.MoveRotation will resulting in a smooth transition between the two rotations in any intermediate frames rendered. This should be used if you want to continuously rotate a rigidbody in each FixedUpdate." and that rb.rotation teleports a rb from one rotation to another

[cobalt solstice]

I asked before here about some local saving data stuff, I'm now trying to look at a login. Everywhere I search is all using firebase but I'm wondering if there's any way I can do a local one at all so that I can personalise what will be used for the login details. Would this be done by just using methods through the local saving data that I mentioned or would it be done otherwise?

[teal viper]

You can implement it however you want, but unless it's using a remote service like firebase, it's gonna be prone to hacking.

[cobalt solstice]

Whole thing should be on a local device, in the project I'm doing it would be for a fixed place not something commercially available

[night mural]

so when you say login, what you mean is like multiple save files? or multiple user profiles?

[cobalt solstice]

User profiles where their times to complete get saved

[night mural]

but no passwords or security or anything

[native seal]

anyone know why OnApplicationQuit is not calling when I exit play mode?

[night mural]

then yeah you can just do that locally, even just using the filesystem (make a folder for each profile and read those/let the user select one on game start)

[cobalt solstice]

I'll be using that I was just wondering if there's a way to do that locally

[night mural]

i think the editor has different quit events

[night mural]

is your filesystem not local? what do you mean locally?

oh sorry

what's the point of a local password?

[cobalt solstice]

It's like, a one place game which multiple people might be using the computer

[night mural]

and those people trust enough to share a computer, but not enough to play their correct profile or whatever?

[cobalt solstice]

🤷‍♂️

[night mural]

basically it depends how secure you want to be

is why i'm asking this

lke if you need real security, it's going to be some work

[cobalt solstice]

I can look at using firebase it's just I can't use library IDs on there

[night mural]

if you just want people to input a username and a password and you have those stored in text (or compiled into the game) somewhere and it's ok if people can find them if they try, that's different

[cobalt solstice]

That's what I was going to use for the login to begin with

[night mural]

if there's no reason for the game to connect to a server i wouldn't want to use firebase

unless you want to store your data in there anyway i guess

[cobalt solstice]

Ye that's why I was checking in the first place, seemed unnecessary

[night mural]

well it's your code so you can have it do anything

if you want to prompt them for a username and password then you can

[cobalt solstice]

Just wasn't sure if I'd be using the regular way to save data

[languid spire]

If you want something which is semi-secure. Encrypt the user data using their username/password as the encryption key

[night mural]

and you'll have to decide how you want that to work and where those passwords come from and are stored and how secure they need to be

[cobalt solstice]

Ahh alr

[night mural]

probably, this would just be a layer on top of that

[cobalt solstice]

Ye I'll have a look at that

Ty

[vale karma]

Quaternion deltaRotation = Quaternion.Euler(playerRotation * Time.fixedDeltaTime);
rb.MoveRotation(rb.rotation * deltaRotation);

if i remove rb.rotation, then the playermodel doesnt rotate, but if i leave rb.rotation in, then the player model rotates really slowly indefinetly until i move the mouse the other way.

i followed the Unity documentation, im trying to get the player model to follow the mouse input

[delicate tangle]

can someone help me when i try put this on bones it says this

they are the same tho

[teal viper]

What about compile errors?

[languid spire]

show both the file name and the class name

[delicate tangle]

ok

[languid spire]

That looks like you are using a lower case i in the filename but an upper case I in the class name

even though we cannot see the full fle name

[native seal]

anyone know why the Awake() on my singleton is being called between scenes even though it is dont destroy on load

[north kiln]

Does it exist also in the scenes that you are loading

[delicate tangle]

no they both have an uppercase i

[native seal]

no

its when i switch back to the scene it was initially in

[north kiln]

So it does exist there

[native seal]

ah yea

how do I fix that?

[languid spire]

if you have your singleton code in Awake and it's done correctly, there is nothing to fix

[night mural]

if your singleton itself were an SO, it would persist between scenes naturally and you wouldn't need to worry about any of this
you could also have a wrapper scene which loads sub-scenes, and then you can put your singletons and any persistent stuff in there so that it's only loaded once

[native seal]

so just make a initilization scene that switches immediately?

[night mural]

yep, or with a little menu with a 'start' button or something, because eventually your game will probably have a menu

[native seal]

aight thx

[delicate tangle]

anyone else know?

[keen dew]

#💻┃code-beginner message

[delicate tangle]

oh there are none

[languid spire]

you have 2 errors there

[delicate tangle]

oohhhhhhhhhhhhhhhhhhh i see that

[languid spire]

duplicate script/class

[bold nova]

Im trying to subscribe to an event in game manager, i realized singleton in it, so theres only one static instance of it, which i initialize in OnEnable, also i have bunch of listeners like background, timer etc. On those script i try to subscribe to an event in Awake method but i get null reference exception because instance is null

Here i set the instance of the session manager
 private void OnEnable()
 {
     if (Instance == null)
         Instance = this;
     else
         Destroy(gameObject);
     Debug.Log("Instance set");
     playerController.OnPlayerDied += EndSession;
 }

and try to subscribe to it, but i get null reference exc
 private void Awake()
 {
     SessionManager.Instance.OnGameOver += FinishTask;
 }

I thought that unity calls OnEnable() first, so by the time code is in awake methods of the background class, instance was already set

[teal viper]

Well, don't subscribe in awake.🤷‍♂️

[teal viper]

Awake first.

Awake and OnEnabe of each object run in pair.

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

[languid spire]

Destroy followed by subscribe to event, not a good idea

why do so many people think Destroy stops code execution?

[bold nova]

well, it is on;y in case another sessoin manager already exist

[delicate tangle]

omg thats you so much its working now

[languid spire]

so you want to subscribe a method that you have just destroyed?

[teal viper]

One tip: don't hide the errors. You might be able to escape from your problems in reality, but the compiler is relentless.

[bold nova]

no, the logic was, if theres no game manager it would assign the first game object to the static insstance field and than subscribe that instance to playerDied event, if one game manager already exist, i dont need that game object and it should be destroyed

[dapper egret]

So if i make my start and awake methods public i would be able to manually call them,need to reinialize for multiplayer?

[languid spire]

yes

[vague dirge]

Hi, how could I mimic a Mario-like jump ? What I mean is that when my character jumps, it can move it the air as if he was on ground, and so he moves to freely during the jump. In Mario, you can alter the jump direction, but slightly, so you don't get frustrated if you land right after an edge for example. It stored the jump direction of my character as a vector, and summed it with the character direction vector, but when I do that, it can't go back for example. If I lower the speed, the whole jump would be slower and the problem is not solved. I think I should maybe set all the others directions "slower" than the jump direction maybe, but that seems too complicated. Does anyone know how to achieve this please ?

[dapper egret]

Excellent will save me so much time thx

[languid spire]

if you are object pooling don't forget you have OnEnable as well which you may need

[dapper egret]

Already using it,everything mosrly works its just hud elements not reinializing after respawn

[languid spire]

then you are probably better using OnEnable & Start rather than Awake & Start

[delicate tangle]

now im trying to put the circled bone into head and its saying that

[languid spire]

yes, exatly what it says

[rare basin]

also this is a code channel

[teal viper]

You can't take it out of it's prefab. You'll need to unpack it.

Also, it's not a coding question.
Also also,I suggest learning the basics first:
!learn

[languid spire]

not even sure why you would want to do that

Hello. I want to save the changed tags and load them when the scene is reloaded. I can't find a way to do this
https://hatebin.com/hmewqflkwr

Tags are changes inside the OnButtonClick method

[languid spire]

not gonna work, you cannot update and save changes to GameObject/Transform data at runtime

not that I'm recommending this, but you could save/load the tags to PlayerPrefs

[cinder spruce]

yes that's i want to do actually, but i couldn't do it the right way so far

[languid spire]

use the gameobject name as the key and the tag as the value ?

[cinder spruce]

In fact what i want to do is to save the color of the changed buttons and load them when the scene is reloaded. This is the only method i could come up with so far

[languid spire]

may I suggest this, it's free and should make your lfe easier for saving Colors
https://assetstore.unity.com/packages/tools/utilities/player-prefs-lite-222004#description

[rare basin]

color is just 4 floats

you can save the floats

then load the color based on these floats

r,g,b,a

[cinder spruce]

it's not one or two objects, it's 30 buttons in an array, that complicates things

[languid spire]

hmmm, my system handles arrays as well

[rare basin]

what's the issue then

save each button's color

"Button1Color" "Button2Color" as a saved strings to player prefs

[languid spire]

I cannot believe you are seriously suggesting that

[rare basin]

for(int i=0; i < buttons.Count; i++)
{
    var saveString = $"Buttons{i}Color";
    Color buttonColor = buttons[i].GetColor();
    //save to player prefs the color 
}

or just JSON it

[willow nexus]

I want this gui popup box to be positioned so the top right corner is where the mouse is.

However, it also needs to be able to adjust for the size of the image inside it, which can change.
I thought i solved it but it changed based on screen size.... so if i fullscreen etc it displays differently

how can i do it properly

current script is just this ```using UnityEngine;

public class CursorFollow : MonoBehaviour
{
public Vector2 offset;
private RectTransform rectTransform;

void Start()
{
    rectTransform = GetComponent<RectTransform>();
}

void Update()
{
    FollowCursor();
}

private void FollowCursor()
{
    Vector2 canvasPosition;
    RectTransformUtility.ScreenPointToLocalPointInRectangle((RectTransform)transform.parent, Input.mousePosition, null, out canvasPosition);
    rectTransform.anchoredPosition = canvasPosition + offset;
}

}```

[cinder spruce]

when i swap the colors of buttons i also swap some floats. But they are handled seperately. How can i use your tool? Do i have to create a seperate script for this?

Line 77 SwapButtonColors, Line 84 SwapStats

[languid spire]

you use my asset exactly as you would use Unity PlayerPrefs, I have just extended the datatypes it works with considerably

[cinder spruce]

ok, imported it. Are there any instructions on how to use it?

[languid spire]

of course, there is full documentation available from the Tools menu or on my website https://stevesmith.software

[gilded sinew]

is there a way to loop through all tiles of a tilemap (which are 3D game objects) and extract their position and name for example

i have a code that is working and is using raycast for that but is there a way to make it without raycast

[cinder spruce]

this is not compatible with my script. I get errors. I think when i add the playerPrefsLite namespace, i can't use the default player prefs system of Unity. If that's the case i'll have to change the entire script

[languid spire]

it should not be, my PlayerPrefs is 100% compatibile with code written for Unity PlayerPrefs

[cinder spruce]

When i added the namespace i got errors for those lines

        PlayerPrefs.DeleteKey("PlayerHealth");
        PlayerPrefs.DeleteKey("PlayerDamage");
        PlayerPrefs.DeleteKey("PlayerSpeed");

"Severity Code Description Project File Line Suppression State
Error CS0117 'PlayerPrefs' does not contain a definition for 'DeleteKey' Assembly-CSharp C:\Users\Ömer\Desktop\2d Samurai Game\Assets\Scripts\StatExchangeMenu.cs 160 Active
"

[languid spire]

my bad, change DeleteKey to Delete

[cinder spruce]

all other keywords are compatible with this tool right?

[languid spire]

yes, at least I'm pretty sure they are, maybe Unity added some new ones since I wrote the asset

Thanks for spotting that, I will update the asset to handle DeleteKey

[cinder spruce]

ok so where should i add the code to get the color of all buttons in all three arrays, inside the SwapButtonColors method?

[languid spire]

show your code

[cinder spruce]

https://hatebin.com/hmewqflkwr

i managed to save the stats, i don't understand why colors are too complicated to save. I think the array thing complicates things

[rare basin]

    public Transform[] healthButtonsParent;
    public Transform[] speedButtonsParent;
    public Transform[] damageButtonsParent;

why are you stroing them in array of transforms

why not Button[]?

i see you are doing GetComponent<Button>() everywhere

[gilded sinew]

guys i could really use help regarding tilemap

[rare basin]

any context? elaborate pls.. learn how to ask questions

how are we suppoesd to know what is wrong

and what is the expected behaviour

[gilded sinew]

so, when i print bounds and local bounds i get numbers that dont correspond with tilemap size

it has 10 000 tiles all next to each other

yet bounds are like its single cell or no cells at all

reason for doing this is i want to itterete through all tiles in tilemap and get their cell positions and name

so i can pair them

[low path]

Where’s “here” being printed?

[languid spire]

tbh and not to be rude, but your code is awful but, you probably want something like this

void SwapButtonColors(Transform redButton, Transform whiteButton)
    {
        if (canSwap)
        {
            Image redImage = redButton.GetComponent<Image>();
            Image whiteImage = whiteButton.GetComponent<Image>();
            Color tempColor = redImage.color;
            redImage.color = whiteImage.color;
            whiteImage.color = tempColor;

        PlayerPrefs.Set(redButton.name,redImage.color);
        PlayerPrefs.Set(whiteButton.name,whiteImage.color);
        }
    }

You then need to see where you do the PlayerPrefs.Get to restore the state

[gilded sinew]

it gets printed just before these bounds, i didnt screenshot it

i really dont understand why are bounds such...

[cinder spruce]

Yesi know, i don't mind. I'm no coder. I can refactor it later. Right now i need something that works.

awake method?

[languid spire]

Awake would be good

[cunning rapids]

What're you trying to do exactly

[languid spire]

I suspect you are looking at the wrong TileMap

[gilded sinew]

i want to itterate through all tiles of a tilemap and store their position and name. I do have code that works using raycast but when using mesh collider, project gets incredibly laggy because of lot of mesh colliders on the scene, so i am trying to do it without it

[gilded sinew]

i checked several times in inspector and i assigned correct one

[cunning rapids]

How're you measuring them?

[languid spire]

this
https://docs.unity3d.com/ScriptReference/Tilemaps.Tilemap.GetTilesBlock.html
works for me when I pass it tileMap.cellBounds

[gilded sinew]

well unity offers cell bounds and then you itterate through them i guess

[gilded sinew]

i will check now steve

well

i never had this line of code

Tilemap tilemap = GetComponent<Tilemap>();

[languid spire]

whoops

#💻┃code-beginner message

[gilded sinew]

actually i shouldnt need it because script is not attached on that tile

but on other one so i am passing tilemap as reference in inspector

[cunning rapids]

Wait I think I'm being stupid but you're measuring a sprite based on tiles right?

[gilded sinew]

uhm not sure what you mean

my tiles are 3D objects

3D hexagons

[cunning rapids]

Oh shit

I misunderstood the question

My apologies

[gilded sinew]

all good

[cinder spruce]

@sry how do i write the PlayerPrefs.Get line? I can't get it right. It's different than the regular playerPrefs. I checked the documentation but it shows an example for an int variable

[languid spire]

what have you written?

[final lark]

Yo, im making a top down shooter.

Im trying to make a gun rotate so that its barrel points at the mouse, but didnt figure a way to di that, so im asking for help here

[cinder spruce]

i copied exactly the playerPrefs lines to awake and change set with get. I got 9 errors

[languid spire]

well that wont work even with Unity PlayerPrefs

[cinder spruce]

ok, i'll give it another shot

[languid spire]

the documentation is pretty clear use either

Color color = PlayerPrefs.Get<Color>("key");

or

Color color;
PlayerPrefs.Get("key", out color);

[fierce shuttle]

What have you tried searching for?

[final lark]

Tbh i didn't search for the problem, i tried a bunch of solutions i made up and they didnt work

Do you have any recommendations for places to search for solutions in?

[fierce shuttle]

I would try keywords in google, maybe something like "unity c# look at mouse" or something similar

[final lark]

Ight

[cinder spruce]

ok that was embarrassing. I need to study more about the playerPrefs

[languid spire]

you might also want to learn about using generics in C#

[cinder spruce]

yeah i need to learn C# better period . That's the bottomline 😄

[languid spire]

no time like the present

@cinder spruce tbh all of this would be much better in a script attached to each button so you can use OnEnable to Get and OnDisable to Set

purely from a design perspective

[late bobcat]

guys going on the unity profiler i noticed this https://gyazo.com/a8fa9841c1882619ab32e2c62974b224 . I'm getting spikes from spriteskin.OnEnable() [Invoke] what can i do to optimize that?

[cinder spruce]

is redImage, whiteImage names of the keys? Why aren't them written as strings?

[languid spire]

redImage and whiteImage are cached Image's. It's so you don't repeat GetComponent like you were doing

if you look at my code you will see I am using the button names as the keys

[fierce geode]

Is using Vector3.project a poor way of giving tight control when it comes to moving a character around? I found that using it and projecting the velocity vector around the players input gives some tight control

[keen dew]

define "tight control"

[fierce geode]

as in, tight as in the time between dictating a direction and the character finally moving in that direction

[slender nymph]

i don't see how Vector3.Project has anything to do with that 🤔

[frosty hound]

Projecting a vector has no bearing on tight controls

[fierce geode]

I thought projecting the velocity vector, basically the forward velocity towards the directions of the players input would give tighter controls

[frosty hound]

The input is already giving you the direction

How fast you accelerate and turn is entirely based on your implementation

But protecting the input isn't going to do anything useful

[slender nymph]

that line has nothing to do with that error. you need to remove the UIElements using directive

[fierce geode]

I found that doing like
rb.velocity = Vector3.Project(rb.velocity,new Vector3(playerinput.x,0,playerinput.y));
gave me tighter control over my character

maybe its just my dodgy code lol

Like this is without the Vector3.project line

and this is the same thing with the project line in.

[slender nymph]

you are using GetAxis instead of GetAxisRaw. the former applies input smoothing, the latter does not

you do not need the line to project the velocity, you just need to stop smoothing the input

[burnt mantle]

hi guys, i have a character controller and when i setup the gravity my velocity.magnitude of the character controller is zero when i move and if i jump its not zero someone can help me pls ?

[slender nymph]

see #854851968446365696 for what to include when asking for help. you're not providing enough info/context which is why you didn't get an answer the first time you asked

[fierce geode]

Okay, the turning circle is not as loose as before. So yeah there was definitely a problem of input smoothing. Could afford to have the movement be tighter, but I could probably mess around with how I deccelerate my character to achieve the same effect.

[cinder spruce]

@languid spire i added these in awake:

 Color redImage = PlayerPrefs.Get<Color>("redButton");
 Color whiteImage = PlayerPrefs.Get<Color>("whiteButton");

no errors but didn't work either

[slender nymph]

you also appear to be multiplying mouse input by deltaTIme which is also a no-no. mouse input is already framerate independent so multiplying it by deltaTime just makes it dependent on the framerate again and also leads to stuttery camera controls

[fierce geode]

Ah okay, I've just kind of assumed when moving something to always apply delta time to keep the movement the same speed regardless of frame rate.

anyway, thnak you @slender nymph ❤️

[cinder spruce]

ok i will try this. The other way is not working for me

[burnt mantle]

So my problem is when i ApplyGravity the variable currentSpeed return 0 and when i disable the ApplyGravity the variable return 7 the actual speed of my game

[earnest atlas]

I have multiple enemies that I want them to use waypoints as coordinates to travel to.

As of now Im using this code https://hatebin.com/zmqmjolqiz

Im not sure if this is good way. I noticed enemies getting stuck on right side of the movement. And I think its doing too much calculations.

Is there better ways to deal with moving multiple objects at same time?

[slender nymph]

multiple calls to CharacterController.Move are probably what is fucking that up. you probably need to combine your gravity and actual movement into a single call. execution order of when Move is being called will also likely affect it
https://docs.unity3d.com/ScriptReference/CharacterController-velocity.html

Note: The velocity returned is simply the difference in distance for the current timestep before and after a call to CharacterController.Move or CharacterController.SimpleMove.

[languid spire]

look at this

        PlayerPrefs.Set(redButton.name,redImage.color);
        PlayerPrefs.Set(whiteButton.name,whiteImage.color);

and then this

Color redImage = PlayerPrefs.Get<Color>("redButton");
 Color whiteImage = PlayerPrefs.Get<Color>("whiteButton");

Spot the difference?

[gritty parcel]
