'ello again fellas.

Sooo be working at this for a little bit and think I have a solution that SHOULD work.

BUT, I've broken something and I really can't see where.

In the Enemy Script, the enemy is looking for a Path and a Formation, but for some reason, now they aren't getting assigned/found to the necessary variables.

Could someone lend me their eyes please and try to see what I'm missing as I just cannot see it. 😦

Animation used i only have one direction and i used script to flip direction when moving

#

if I put a layer on an empty gameobject, will it still get picked up by a sphereOverlap even if it has no collider?

#

aight, i'll just put it on a physical one then

#

cheers

you have to show me where the object goes when you flip, cause nothing in the code wrong

I'm making a conveyor belt and when the objects move from 1 conveyor to another they get slower or stop moving for a small period (probably move slower)

public class BaseConveyor : Building
{
    [SerializeField] private float speed = 1f;
    [SerializeField] private GameObject conveyorBelt;
    
    private List<Ore> ores = new List<Ore>();
    
    private void OnCollisionEnter(Collision other)
    {
        if (other.gameObject.TryGetComponent(out Ore ore))
        {
            ores.Add(ore);
        }
    }
    
    private void OnCollisionExit(Collision other)
    {
        if (other.gameObject.TryGetComponent(out Ore ore))
        {
            ores.Remove(ore);
        }
    }
    private void FixedUpdate()
    {
        foreach (var ore in ores)
        {
            if (ore != null && ore.Rigidbody != null)
            {
                ore.Rigidbody.velocity = conveyorBelt.transform.forward * speed;
            }
        }
    }
}```

the colliders of both conveyors are overlapping, so that shouldn't really be the problem... Right?

are there any scripts that may help me with 3D grid building (Survival based game) ive looked around and keep finding for 2D games

meager steeple

#

having these issues, i feel its all related to one thing but not sure what, i have a duplicate project with a different name (for building to another platform) and im not getting any errors from that project

image.png
#

its odd because this project has worked before and i've built from it

slender nymph
#

Did you recently start using asmdefs?

tawny hedge
#

i've never heard of it or seen the name so i doubt it

#

is there a way of checking if i started using it?

slender nymph
#

Yeah, search for asmdef files in your scripts folder

tawny hedge
#

nope, havent got anything relating to asmdef

# meager steeple i take damage, and the collisions between the layers of the spikes and player ar...

im guessing this would be because i have in my script to ignore layers when taking damage, apart from if the health is 0. but when its taking 2 damage it will ignore layers, but it doesnt reactive the layers afterwards

public class EnemyCollision : MonoBehaviour
{
    public GameObject GameOverUI; // selecting the game over game objects from the hierarchy

    private void OnCollisionEnter2D(Collision2D collision)
    {
        if (collision.gameObject.CompareTag("Enemy")) // checks for collision with specific tag
        {
            Debug.Log("collision");
            HealthManager.health = HealthManager.health - 1;
            if (HealthManager.health <= 0 ) // checks if health is 0 or less
            {
                GameOver(); // calls separate function for game over
            }
            else // player is not dead
            {
                StartCoroutine(GetHurt());
            }
        }
        IEnumerator GetHurt()
        {
            Physics2D.IgnoreLayerCollision(8, 9 , true); // ignoring collisions between 2 layers
            yield return new WaitForSeconds(2); // 2 second timer
            Physics2D.IgnoreLayerCollision(8, 9 , false); // stops ignoring collisions between 2 layers
        }
    }

    void GameOver()
    {
        GameOverUI.SetActive(true); // shows game over screen
        Debug.Log("Player Died"); // logs in console
        Time.timeScale = 0; // freezes time

no, its in the assets/plugins/codeassist/editor and then theres an amsdef and amsdef.meta

slender nymph
#

Then it's not relevant. It would have to be in either Assets or Assets/Scripts

#

ahh okay

im guessing i could run Physics2D.IgnoreLayerCollision(8, 9 , false); with the awake function as a work around, but it doesnt really solve it

I have a simple 3d capsule, with a Character Controller and a Capsule Collider
I have another plane below the character, with a mesh collider.

However, my capsule goes right through the mesh, what am I doing wrong?

slender nymph
#

for starters, the CharacterController is already a capsule collider so you don't really need both (unless you have a specific reason for it). but also how are you moving the CC and is the mesh collider convex or non-convex

untold raptor
#

is there a way of speeding this up? It got much slower after I added the starter assets third person controller. is it due to the game getting bigger in file size?

Unity_WRc5ndJVho.png
slender nymph
#

is it actually stuck on Application.EnterPlayMode? because if so, that could indicate an infinite loop in your code. otherwise you really just gotta deal with how long it takes to enter play mode unless you mess with the enter play mode options (do not do so without understanding how they impact your project)

#

also the size of your scene impacts how long it takes to enter play mode as well

cosmic dagger
tulip slate
#

that actually seemed to fix it

untold raptor
slender nymph
#

if it isn't getting stuck, then how long it takes to enter play mode depends on a few things, including the size of your scene, how much work you do in the earliest parts of the first frame (like in Awake), as well as those enter play mode options i mentioned (though, again, do not mess with them without researching how they will impact your project and work flow)

#

oh and read/write speed of your disk also plays a part. i was doing so much waiting when i had my project on an old HDD but after moving it to an NVME SSD it does everything (including entering play mode) much quicker

untold raptor
#

oh right okay that makes sense, I'm working on my HDD atm i'll transfer it to my SSD later

tawny hedge
slender nymph
#

now would be a good time to set up some sort of version control if you don't have it already so you can avoid issues like that moving forward

tawny hedge
#

yeah 😂 thats true

#

i was actually in the process of getting it sorted recently, maybe thats how it managed to mess up, cause i was having an issue importing from cloud to another device

queen adder
#

whatif what if, unity exposes most component classes? Will it like hurt performance?

frosty hound
#

Expose in what sense?

modest sluice
# 
            var points = new List<Vector3>();
            AxiomPoints.Add(new Vector3(1, 0, 1));
            AxiomPoints.Add(new Vector3(1, 0, -1));
            AxiomPoints.Add(new Vector3(-1, 0, 1));
            AxiomPoints.Add(new Vector3(-1, 0, -1));
            
            for (var i = 0; i < AxiomPoints.Count; i++){
                points.Add(AxiomPoints[i]); //instead of this line, is there a way to add all of the points in AxiomPoints outside the loop?
                points.Add(new Vector3(AxiomPoints[i].x, AxiomPoints[i].y + stemLength, AxiomPoints[i].z));
            } ```
#

axiomPoints is a list of the same type

slender nymph
#

then pass AxiomPoints into the constructor for the points list

modest sluice
#

var points = AxiomPoints; ?

slender nymph
#

no, pass it into the constructor. var points = new List<Vector3>(AxiomPoints);

modest sluice

(Camera does not contain a definition for main)

you probably have your own class called Camera causing a conflict

Oh I fixed it

yeah I just created an enum called Camera

Is there any easy way to tell a cinemachine brain (Make this virtual camera go live now)?

# frosty hound Change the priority of the virtual camera

    switch(camera)

        case Cameras.Default:

            foreach (GameObject go in _Cameras)
            {
                if (!go.name.Equals("_DefaultCVC"))
                {

                }
            }

        break;
    }
}
#

That's why I said an easy way xD

frosty hound
#

Cache the active camera, and when you want to switch it, turn the active priority to 0, and the new active camera to 1. Cache the new active camera.

polar acorn
#

Unless there's a higher priority camera enabled, the most recently enabled camera is the one that will be active

#

So if you just never change priority, the way to make a specific virtual camera go live is to just enable it

slender nymph
hot palm
#

True

#

I cached them before in a list tho

queen adder
# 

    [ReadOnly] public GameObject latestActive; // Keeps track to the last panel opened, close that when another panels wants to open
    public GameObject LatestActive
    {
        set
        {
            MainGUI.SetActive(!value);
            if(latestActive)
            {
                if(latestActive != value)
                {
                    latestActive.SetActive(false);
                    value.SetActive(true);
                    latestActive = value;
                }
            }
            else
            {
                value.SetActive(true);
                latestActive = value;
            }
        }
    }```this pattern can work, just need some change to use cinemachine instead

#

Is this not foldable? damn

#

So using the name is only a matter of me copy and pasting new ones correctly inside this script

#

But I understand the general concern

slender nymph
#

until you accidentally change the name of one of the objects at runtime and suddenly your code no longer works

#

or you spell it wrong

hot palm
#

uh no

#

because the object is cached in the variable

#

wait

#

nvm

#

ur right

#

I miscoded smth

#

I dont want to check the name of the object

#

but the name of the variable

queen adder
#

huh

hot palm
#

How do I do that? 🤔

slender nymph
#

you don't. you have two variables, just use the one you need to use at the point you want to use it

queen adder
#

you cache the object and use that

slender nymph
#

also consider making your variables CinemachineVirtualCamera instead of GameObject. that would eliminate the need for the GetComponent call

hot palm
#

I did that before

slender nymph
#

so instead of all of this:

foreach (GameObject go in _Cameras)
                {
                    if (!go.name.Equals("_FreeLookCVC"))
                    {
                        go.GetComponent<CinemachineVirtualCamera>().Priority = 90;
                    }
                }

you would just have _FreeLookCVC.Priority = 90;

hot palm
#

Deleted it bcs I couldnt check the name

#

but is smarter yeah

#

But how would I do the condition then?

slender nymph
#

what condition? you have the switch statement already, you know which you need to modify based on the case

hushed hinge
slender nymph
polar acorn
eternal falconBOT
hot palm
#

It would be this, but as you said, using the name is not good in general.

foreach (CinemachineVirtualCamera vc in _Cameras)
{
    if (!vc.name.Equals("_FreeLookCVC"))
    {
        vc.Priority = 90;
    }
}
slender nymph
#

you do not need the loop if you only have the two variables

hot palm
#

Yeah but I will have ~20 cameras

#

When walking to a specific point in the world, I want to blend to cameras

slender nymph
#

then we are back to my suggestion of checking a tag or some property on the vcam (or other component on the objects) instead of relying on the names

        }
    }

    private void RemovePickups()
    {
        _amountPickedUp -= 100;

or if it's something to di wtih "_text.text = _amountPickedUp.ToString();" since it is line 18

also at this point, you may as well just scrap the whole system. keep track of only the most recently activated cam, and just lower the current camera's priority, raise the new one's priority then set it as current

#

no need for a list or a loop so your method is o(1) instead of o(n)

you're forgetting to assign the _VirtualCamera to _CurrentCVC so that next time this is called with a different camera the old one is set to 0 priority

Best way to learn the convention is read through the article yourself here. If you don't understand the terminology, another way is to program next to someone who is also doing it. Other than that, it's overcomplicated for what you're doing, you aren't working in a full team I assume, so it isnt required at all

C# identifier names - rules and conventions - C#

Learn the rules for valid identifier names in the C# programming language. In addition, learn the common naming conventions used by the .NET runtime team and the .NET docs team.

#

What you do is very normal and a lot of people do that in Unity

I have a component that I am adding to an object. After adding it, I'm trying to modify the component's values.

LootFall lootFall = coinPrefab.AddComponent<LootFall>();
lootFall.dirtPlatform = dirtPlatformsStatic[pressedKey - 1];

LootFall contains a public GameObject dirtPlatform. When I attempt to supply it with the GameObject, the IDE has no errors, but Unity has this error:

'LootFall' does not contain a definition for 'dirtPlatform' and no accessible extension method 'dirtPlatform' accepting a first argument of type 'LootFall' could be found (are you missing a using directive or an assembly reference?)

How do I modify the value of this component?

You will likely need to reassign it if it was in the inspector

# carmine sierra sorry why exactly?
  1. GetComponent is slow
  2. Your code is overly complicated because you have to keep getting the component when you want to do anything with it
  3. All components have .gameObject to reference the object it's on
carmine sierra
austere hedge
polar acorn
#

There's basically no reason to ever reference an object as GameObject, use the component you actually want, and if you need to access any of the GameObject's methods (usually SetActive or CompareTag, most others aren't used often) then you can just get the gameObject from the component.

#

Going up the chain is fast. All components are on a GameObject, so they all have a readily accessible .gameObject property. But not all objects contain all components, so the process for getting something on the object is slower

carmine sierra

you change the type of that variable. Presumably it also shouldn't be of type GameObject

Does every SpawnWood have a WoodCollisionDetection?

carmine sierra
#

no spawnwood is a script

polar acorn
carmine sierra
#

woodcollisiondetection is a script inside of every wood instance

#

which is from a prefab

polar acorn
#

Does every object with a SpawnWood script on it also have a WoodCollisionDetection script on it

carmine sierra
#

every object in spawn wood which is a wood instance yes

polar acorn
#

Then you'd just need to do woodInstances[i].collisionDetection.broken

#

or whatever you decide to name the variable

cause theres only one spawnwood

I'm working on some basic movements, and I'm wondering how I should implement these in terms of structure so it'll be good.
For example, I want to be able to dash when pressing WW/AA/SS/DD consecutively.

The way I implemented this is somewhat like this

        foreach (KeyCode keyCode in System.Enum.GetValues(typeof(KeyCode)))
        {
            if (Input.GetKeyDown(keyCode))
            {
                if (IsEligibleForDash(keyCode)) // checks only WASD
                {
                    if (lastTapTimes.ContainsKey(keyCode) && Time.time - lastTapTimes[keyCode] < doubleTapTime)
                    {
                        StartCoroutine(PerformDash(keyCode));
                    }
                    lastTapTimes[keyCode] = Time.time;
                }
            }
        }

    IEnumerator PerformDash(KeyCode keyCode)
    {
        isDashing = true;
        Vector3 dashDirection = GetDashDirection(keyCode); // just transform.forward / backward /  etc
        dashDirection -= transform.up * Mathf.Tan(dashDownwardAngle * Mathf.Deg2Rad);

        float startTime = Time.time;
        while (Time.time - startTime < dashDistance / dashSpeed)
        {
            characterController.Move(dashDirection * Time.deltaTime * dashSpeed);
            yield return null;
        }

        isDashing = false;
    }

Now I'm wondering, should this be in a separate script entirely? What if in the future I add different combos? Like dashing with a slash, it should behave differently I guess.

I mean, yeah, there are tons of ways to do that. Usually the person asking would provide some details we could use. how you move objects is crucual to this

When you googled knockback, what did you find?

If you call Instantiate on a component, it still spawns the whole object, it just returns that type

I'm guessing the object with the PickUp script is spawned in at runtime

Otherwise you could just drag it in

If your PickUp objects exist in the scene, you should just make a public field and drag in this object. Since you haven't done that I assume the PickUps are spawned at runtime?

Okay, so we can get rid of the .GetComponent from that if, it shouldn't break anything. Since the log isn't happening, then broken is not true. Put this log above your if statement:

that works but not breaking the wood instance

# ivory bobcat Are there any errors?

Only when it runs, because the Enemy's can't find the Path and formation objects. It's that what is confusing me cause it was working find before I reworked a bit. And I can't see where it's broken.

            Debug.Log(transform.gameObject.name + "targetPosition = " + lootTopHeightFloatingPosition.ToString());
            Debug.Log(transform.gameObject.name + "speed = " + speed.ToString());
            Debug.Log("Still in the while loop.");
            // Move one step toward the target at our given speed.
            transform.position = Vector3.MoveTowards(
                    transform.position,

            // Wait one frame then resume the loop.

Even though the two positions end up matching, the while loop keeps going so I end up overshooting my mark.

so i found an issue in that i had an if statement (before the for loop to check for the broken bool), which required that spawnwood.placing was true, as there was a null reference error previously. However, placing is only true when the user is placing wood, but if you click the shop again (to deselect wood), placing becomes false. The issue i solved from removing that is that the player would never be firing the slingshot and placing at the same time, but now i get this:

You'll need to look at where you're adding things to the list and see what's coming in as null

# hushed hinge

Looks better but you could probably also do away with the guarding if-statement now. If you still get an null reference exception, that would mean that pickups is null and needs to be assigned from the inspector or by whoever spawned this object.

@slender nymph I missed a detail. It overshot, but it went back. The logs indicate that the position has been reached, so even if something was affecting its position, it is hitting its mark but it's still not escaping the while loop since you can see the position has been hit 5000 times.

well that is certainly odd. Vector3's equality operator is overloaded to return true when they are approximately equal so it's very strange that the condition is evaluating as false. it's less good, but you could check the distance and Mathf.Approximately with 0

carmine sierra
# polar acorn Yes

I am only appending from the updatewoodinstances() function using the add method

#

Unless that function itself has something wrong with it, i am not sure

#

but i dont see anything wrong with it

polar acorn
#

See if it's ever null when you add it

carmine sierra

Which means when you try to use the object in the list, it'll throw a null reference

Is your list supposed to contain nulls?

So, you should probably add a != null to that check you make before adding it to the list

carmine sierra
#

i see what it is, i add one every time there is a new value of woodinstance, and as the game starts with it being null, it adds that to the list

@slender nymph If I set it to 8 floating points I can see that it's just a hair off.

image.png
slender nymph
#

right but as i've already pointed out the equality operator for Vector3 is overloaded to account for that

south sky
austere hedge
slender nymph
#

that is how you compare it to 0

austere hedge
# slender nymph that is how you compare it to 0

I changed the debug line to use MathF.

Debug.Log($"{name} is moving at {speed} units per second from {transform.position:F8} to {lootTopHeightFloatingPosition:F8} which is {Vector3.Distance(transform.position, lootTopHeightFloatingPosition):F8} units away. Has reached destination? {Mathf.Approximately(Vector3.Distance(transform.position, lootTopHeightFloatingPosition), 0)}");
image.png
#

Still says it hasn't reached its destination.

carmine sierra
#

ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

what could be a cause of this error?

summer stump
austere hedge
#

@slender nymph I'm still researching, but maybe it's because I am setting the position using "new".

lootFall.lootTopHeightFloatingPosition = new Vector3(CurrentDirtPosition.x, CurrentDirtPosition.y + 2.2f);
lootFall.lootRestingPosition = new Vector3(CurrentDirtPosition.x, numPadKey.CurrentDirtPosition.y + -1.1f);

Vector3 Equals not working

EDIT: I’ll leave my original answer, snide parts about not posting code removed ;), for others in case they have that issue, but I believe your issue is that you’re using Contains to check if one vector is equal to another vector, but you can’t do that because the = operator of vectors create new vector instances. I can’t find specific documen...

ah so it looks like unity's epsilon value is 0.0001 which is just ever so slightly smaller than your value of 0.0000124

#

that's actually hilarious that you are prevented from using unity's tools that help prevent floating point imprecision issues . . . due to a slightly bigger floating point imprecision issue

How can I check if a specific action is done? I would have thought similar to this. I want to check if it's the action called "Pause".

if (context.action == CharacterControllerMap.SimpleMovementActions.Pause)
slender nymph
#

what is the context of this code?

hot palm
# 
private void Pause(InputAction.CallbackContext context)
{
    if (context.action == Pause) Cursor.lockState = (Cursor.lockState == CursorLockMode.Confined) ? CursorLockMode.Locked : CursorLockMode.Confined;
    else Cursor.lockState = CursorLockMode.Locked;
}
slender nymph
#

so assuming you've subscribed this to the Pause action's performed event and nothing else, then you can safely assume this is reacting to the pause action

#

you do not need to check that it is

hot palm
#

Yeah but I subscribed with ESC and LMB

#

Could do seperate ones or simplify this

#

But do you know how to ask what action the context called?

slender nymph
#

i honestly don't understand what you are trying to do

hot palm
# 
characterControllerMap.SimpleMovement.Pause.started += Pause;

characterControllerMap.SimpleMovement.Interact.started += Pause;
#

I want to toggle pause with esc

slender nymph
#

why did you subscribe the Pause method to the Interact event

hot palm
#

If I click I want to unpause

#

Okay I dont do that and only have esc toggle pause, thanks- xd

#

Do drag and drop references not work in a build btw?

#

That'S the reason I did this

#

To check the debug log in my build

slender nymph
#

you should instead make whatever is subscribed to the Interact event check if the game is currently paused and unpause it if it is instead of trying to check what invoked the method

slender nymph
#

what would be the point in the ability to drag a reference into the inspector if it didn't work in a build

hot palm
#

idk what theme for this is but I get nullpointers in my build

#

Which I do not in the editor

#

So I assumed that's the problem somehow

its pretty straight forward.. here is your code :

Vector3 move = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));
controller.Move(move * Time.deltaTime * speed); // Move the object using the transformed move vector```
and here is the instructions i gave you : 
```cs
Vector3 move = new Vector3(Input.GetAxis("Horizontal"), 0, Input.GetAxis("Vertical"));

move.Normalize(); // normalize the move vector
move = transform.TransformDirection(move); // transform the move vector to match the direction of the object

controller.Move(move * Time.deltaTime * speed);

if you want to be synced with the physics engine, that's what FixedUpdate is for

(you should also not be using AddForce in Update)

why shuldnt i?

because it will lead to inconsistent behavior depending on your framerate

The physics simulation needs to happen at a fixed timestep or you will not get consistent behavior, and no this can't be fixed with Time.deltaTime

Actually normalizing here is not good because it'll take a very noticeable amount of time for the player to stop moving, since GetAxis is smoothed you'll have a few frames between the moment you release the keys and the vector falls back to exactly (0, 0, 0)

The TransformDirection works perfectly, so the issue is in the Camera, isn't it?

the camera child doesn't (and shouldn't) need to be rotating separately from the parent

perhaps the camera isn't rotating ur CC

if ur CC doesn't actually rotate then the TransformDirection isn't actually gonna work for ur usecase
not by applying it to the cc's transform atleast
