thank you

knotty sun
#

Do you have multiple EnemyTakeDamage components in the scene?

long quarry
knotty sun
#

So these

private void OnEnable()
    {
        FindObjectOfType<EnemyTakeDamage>()?.AddEnemyObserver(this);
    }
    private void OnDisable()
    {
        FindObjectOfType<EnemyTakeDamage>()?.RemoveEnemyObserver(this);
    }

Just find the first one so all of the actions are being set on only one component

okay i am trying now

hello, how do i make an object move like a wave pattern ( a sin wave) diagonnaly using rigidbody2d? i have been stuck on this for quite some time.

# long quarry is this true to send codes (i use it first time) https://gdl.space/wosusagegi.cp...

Seems like there are 2 problems here

  1. You are using FindObjectOfType which will get the first component found, like stated above, maybe you should use GetComponent instead (I'm not sure, since I dont know your setup), this is why only one of your ship trigger the flashing
  2. You are triggering OnDamageTaken to all observer, which is why all your ship flash when one of them get shot. I think you should also pass which gameobject is taking damage to the TakeDamage function, then compare it inside the loop, and only trigger if the gameobject matches
#

Not very efficient way if I may say, compared to directly call OnDamageTaken on missile hit 🤔

long quarry
#

@mild coyote bro do you believe me when i changed to getcomponent<> it fixed

#

thank you so much for your help I'm in game again

Hello i have the following problem and i can't figure out what i did wrong here:

using System.Linq.Expressions;
using System.Numerics;
using Unity.Entities;
using Unity.Mathematics;
using UnityEngine.InputSystem;
using UnityEngine.InputSystem.Controls;
using UnityEngine.UI;

public partial class PlayerInputSystem : SystemBase
{
    private Controls controls;

    protected override void OnCreate()
    {
        if (!SystemAPI.TryGetSingleton<PlayerInputComponent>(out PlayerInputComponent playerInputComponent))
        {
            EntityManager.CreateEntity(typeof(PlayerInputComponent));
        }

        controls = new Controls();
        controls.Enable();
    }

    protected override void OnUpdate()
    {
        Vector2 moveVector = controls.ActionMap.Movement.ReadValue<Vector2>();

        SystemAPI.SetSingleton(new PlayerInputComponent { movement = moveVector });

    }
}

public partial struct PlayerInputComponent : IComponentData
{
    public Vector2 movement;
}

i get an error: InvalidOperationException: Cannot read value of type 'Vector2' from composite 'UnityEngine.InputSystem.Composites.Vector2Composite' bound to action 'ActionMap/Movement[/Keyboard/w,/Keyboard/s,/Keyboard/a,/Keyboard/d]' (composite is a 'Int32' with value type 'Vector2')

i set up everything as a Vector2 in the ActionMap - what am i doing wrong?

Controls is the autogenerated Script from the input system

It makes no sense that a keypress would return a Vector2

remove using System.Numerics; and add using UnityEngine;

Interesting question, how can I make the inspector wrap the shown variable names?
For example, someVeryLongVariableNameThisShouldNotBeThisLongThisIsJustAnExample.

This would be shown as an unbroken line, and I would like it to wrap, if that's even possible.
Something like this:
someVeryLongVariableName
ThisShouldNotBeThisLong
ThisIsJustAnExample

I like to have my inspector window smaller in general, but I also like to see the full name of all of my variables.

can unity make vscode see the packages? example: when editing shaders and searching for a struct i expect to see stuff popping up from includes found within packages. my current workaround is to add package cache folders to the vscode "workspace" but it's janky and has to be done again each time i switch projects, you'd expect that the IDE you open the project with can see everything in assets and packages as if they're first class files

#

is there way to convert worldSpace rotation to localSpace?

#

we used to have RotateAroundLocal back then, but they deprecated it sadly

little meadow
#

something like worldRotation * Qutarnion.Inverse(transform.rotation) will give you local rotation in transform

#

but you may need to inverse the other one or multiply in the other order 😅

craggy veldt
#

ok will give a try, thanks

#

Does anyone know how to override the ```unity-collection-view__item:hover```` class in USS? Im unable to remove an Hover pseudo state from the ListView items..

knotty sun
muted furnace
knotty sun
#

but the USS on the Listview should affect all children

#

tbh I gave up on Unity USS a long time ago because it breaks so often

muted furnace
# 
/* Background color of the item when it is being hovered */
.ann-listview > .unity-collection-view__item:hover
{
    background-color: red;
}

.ann-listview:hover {
    background-color: red;
}```
#

this does not work

#

i dont have the option to give up on UITK, because im using it for my job

#

i know it used to work, im using 2023.2, and somehow it stopped working

knotty sun
#

I still use UITK a lot, I just program everything rather than relying on Unity

muted furnace
#

well do you know how to remove this ugly hover from script then?

#

because im unable to remove the default classname either

#

i want the whole hover to be gone

knotty sun
#

you don't want to remove the class, that would break too much. The only thing I can suggest is use the UITK debugger and see what can be done in that

muted furnace
#

what could i do in the debugger? Only thing i can find in there is once i remove the ".unity-collection-view" class, the hover is gone

#

the interesting part is that the background color is working

image.png
knotty sun
#

really this

.unity-collection-view__item:hover {}

should override default behaviour

muted furnace
#

the pseudo state is not

#

yeah that doesnt work unfortunately..

knotty sun
#

as I said, USS is so broken

muted furnace
#

it used to work before i upgraded to unity 2023.2

knotty sun
#

Ha, Non LTS, you are definitely on your own there

muted furnace
#

I had to upgrade because of the bug fixes and features UITK brought in that version.

#

we also have Unity's starter success and they suggested we kept using UITK

knotty sun
#

UITK is great, but I program everything because there are so many breaking changes between versions

muted furnace
#

Yeah some things were broken after i've upgraded. Especially the event dispatching, that become totally different >.>

for some reasons when i instantiate my prefab the values are lost

i didnt had this issue yesterday, I am not changing those variables in code

image.png image.png
#

left : in prefab
right : when playing

#

in edit mode, when i drag and drop my prefab in the scene i also have this issue

#

got fixed after i reset the component and applied values again, weird

does anyone know EditorAttributes ?

How do I get the size of a stretched RectTransform? Both Debug.Log(viewport.rect.size); and Debug.Log(viewport.sizeDelta); return (0, 0).

image.png
knotty sun
hard estuary
heady iris
#

well, then your viewport has zero width and height!

#

It seems odd for the Viewport to have values driven by ScrollRect

#

ah, it's because of the scrollbars, isn't it

knotty sun
heady iris
#

indeed; removing the scrollbars removes the contorl by the ScrollRect

hard estuary
#

Alright, so I just need to refer its parent. Got it. Thanks @knotty sun and @heady iris

heady iris
#

well, the viewport should have a non-zero size, given that it has a Mask on it that will hide anything that isn't covered by the mask

round violet
#

does anyone knows how dotween works ? i got a question regarding this

fringe ridge
#

i have objects spawning in my game, which have a Hover script, that basically makes them rotate and go up and down slowly (think coins on the ground). when i build for android with deep profiling, i see that it makes 220 + calls each frame, but that stuff only uses 1ms per frame, Transform.Rotate is more expensive and uses 4 ms. I will move all that stuff to a simple rotateall script, that has a list of the transforms, but is it possible to rotate the objects more efficiently?

#

or is this something i shouldnt even worry about, since profiling adds a huge spike to the performance, and that 5 ms will be something like 0.05 in normal build?

heady iris
#

Turning on Deep Profile makes everything significantly slower, yes

#

you can look at what percentage of the total frametime is taken up by those methods

#

but that will still unfairly penalize faster methods

#

you're adding a constant cost to each method call, essentially

knotty sun
#

that doesn't sound so bad, but if you want to optimise it further you don't need to rotate all the coins on every frame, you could split them so you rotate 55 coins every 4th frame for example

fringe ridge
#

just to have a clear mind on that, ill pool them all into one script and instead of .Rotate will set quaternion directly, and as you said, maybe do that every 4th frame

knotty sun
#

what I meant was if you have 220 coins, split those into 4 batches of 55 and then run a routine which rotates one batch each frame

fringe ridge
#

ooh

#

i suspect the position of the traveller is being skewed somehow

tropic kiln
#

Heya, I'm doing some procedural object placement but getting some funny results. My current method is:

  • Sample density noise value [0->100]
  • If position vector hash code < density noise value, then place object

Note that the object positions are pre-determined through a sampling algorithm, this is simply just choosing to include or exclude the object based on the density.

But it's really not looking great at all, there's almost no sign of the noise having any effect. Could it be the hash function not being uniform or something?

heady iris
#

well, without seeing your code, we can't say very much

#

maybe your noise scale is way off

tropic kiln
#

Nah I've tried changing it. There's not actually that much code to show tbh

heady iris
#

have you looked at the actual values you're getting from the noise function?

#

e.g. logged a few points or drawn the values to a texture

tropic kiln
#

No but it's perlin from a library that i've been using no problem in other parts of the project so.

// Where points is the distributed points
for (int i = 0; i < points.Count; i++) {
    Vector3 worldPos = data.offset + new Vector3(points[i].x, 10000, points[i].y);

    float foliage_density = GetFoliageDensityAtPoint(worldPos.x, worldPos.z);
    float chance = Mathf.Abs(worldPos.GetHashCode() % 100);

    if (chance < foliage_density) {
        commands[i] = new RaycastCommand(worldPos, Vector3.down, QueryParameters.Default);
    }
}

    public float GetFoliageDensityAtPoint(float x, float z) {
        float foliage_noise_val = foliage_map.getNoiseAtPosition(x, z);
        float foliage_curve_val = foliage_curve.Evaluate(foliage_noise_val);

        return foliage_noise_val * 100;
    }
heady iris
#

so is foliage_density changing?

tropic kiln
#

Yes, sorry there's some outdated stuff im there

heady iris
#

put it back!

#

the point is to check if the random values are changing

#

you can't debug if you don't do any actual analysis

tropic kiln
#

No all of that was redundant. The values are changing but the method of filtering them out based on density is not working very well

#

Let me just print the highest and lowest vals for each chunk rq

heady iris
#

GetHashCode probably isn't producing very uniformly random results

#

Vector3's GetHashCode is return x.GetHashCode() ^ (y.GetHashCode() << 2) ^ (z.GetHashCode() >> 2);

#

and I'm pretty sure that int's GetHashCode is just return this;

#

oh wait, these are floats

tawdry jasper
#

So I used the unity's starter assets thirdperson controller as a base and I now that I'm inspecting it closely because I need to tweak something I noticed this line:

                // note T in Lerp is clamped, so we don't need to clamp our speed
                _speed = Mathf.Lerp(currentHorizontalSpeed, targetSpeed * inputMagnitude,
                    Time.deltaTime * SpeedChangeRate);```
passing deltaTime * speedchangerate (which is 10f)  as the third param to Mathf.Lerp is wrong right? T might be clamped but deltaTime*10f is just going to be a similar number every frame, not increasing towards 1?
tropic kiln
heady iris
#

To check if this is the problem, just use Random.Range(0, 100) and see what happens

tropic kiln
#

Alright will do 👍

tropic kiln
fervent furnace
#

use unity.mathematics.random

tawdry jasper
heady iris
#

You can construct a System.Random and use that, or use the unity mathematics random

round violet
#

is it possible to make a variable of the "same type" of this ?

image.png
#

if not, how can i combine RigidbodyConstraintss ?

static matrix
# 
AdvanceTimer += Time.deltaTime*Random.Range(0.4f, 2);
        if(AdvanceTimer>=30){
            
        }

is this a solid way to do something after a semi-random amount of time?

heady iris
#

It depends on the distribution that you want

#

If you want a uniform distribution between 0.4 and 2 seconds, then you should just calculate a delay once

# 
float eventTime = Time.time + Random.Range(0.4f, 2f);
#

Your code will not produce a uniform distribution. I'm not exactly sure what it'll look like..

#

Something like a binominal distribution, I guess

round violet
heady iris
#

well, maybe. it could be a custom property drawer

#

you can try serializing a RigidbodyConstraints and seeing how it appears

#

(the editor draws the entire component inspector; a property drawer just draws a single property)

round violet
#

i was looking for doing a sort of liste, and in script having it combine all values

# 
        m_Rigidbody.constraints = myList[0] | myList[1] ...;
heady iris
#

you could use LINQ's Aggregate method

# 
rb.constraints = list.Aggregate(RigidbodyConstraints.None, (total, next) => total | next));
round violet
#

ty ill try

heady iris
#

This will combine every element of the list; the starting value is the first argument

round violet
#

also, i have a GO with a RB and a BC
when i freeze all pos and rot of the RB, i can go through the GO

why ?

heady iris
#

i don't know how you're moving, so I can't really say

#

i'm guessing that you normally push the box around

round violet
#

the player moves with its rigibody

heady iris
#

by setting the rigidbody's position?

round violet
#

if i remove the RB of the cube, the cube blocks the player (as inteaded)

#

MovePosition

heady iris
#

perhaps the player expects to be able to shove the other rigidbody out of the way

#

so it moves as if it could do that

round violet
#

mh

#

i wish i could just enable/disable a RB

#

even if i remove the freeze position on the RB of the cube, the player sometimes go through instead of pusing

i got a gameobject with a rb, its a child of another gameobject

since it has a rb, it can be moved around, but the parent wont follow

what would be the best clean way to move the parent with the child ?

i cannot move the rb on the parent

for now the only solution i found is :

  • get the position of the child
  • set the parent position to that
  • set the position of the child to 000

but it will probably break the physics

heady iris
#

perhaps your hierarchy is wrong

#

why is this thing parented to that object?

heavy hare
naive swallow
heavy hare
#

how is it something likfe gameobject.find()?

image.png
round violet
heady iris
#

okay, but that doesn't really answer the question

#

why is the cube parented to the empty?

round violet
#

I never put a 3d object as the prefab parent

#

I guess i could swap and add a third child

heady iris
#

okay, so put the rigidbody on the parent, then

#

that's fine

#

it'll use all of the colliders that are parented to it

round violet
#

Isnt the rb affected by the collider ?

heady iris
#

i don't know what you mean -- it will use all of the colliders that are parented to the rigidbody

round violet
#

I want the rb to use the box collider that isnt a trigger

heady iris
#

Yes.

#

Every collider that's a sibling of the Rigidbody or parented to the Rigidbody's object will be used

round violet
#

Well thats why i didn't put it in the parent in the first place

#

Because the trigger collider is very big

#

I dont want the rb to use it

heady iris
#

It's a trigger collider.

#

It will have no effect on the movement of the Rigidbody.

round violet
#

So the rb doesn't use triggers

heady iris
#

trigger colliders aren't solid

#

rigidbody movement depends on solid colliders

round violet
#

Then thats great

heady iris
#

MonoBehaviours that are siblings of the Rigidbody will receive trigger messages when a child's trigger collider hits something

#

(MonoBehaviours on the child object will also receive the message)

Can anyone tell me how to manually set PointerEventData properly?

I have the following end drag method:

    {
        if (eventData.button == PointerEventData.InputButton.Left)
        {
            Debug.Log(eventData.pointerCurrentRaycast);```

In case I do proper drag and drop, it works just fine and I get expected pointerCurrentRaycast. However, when I try to manually use the method, my raycast doesn't see anything... My guess is that this is not correct way of inputing PointerEventData. Any tips please?

This is how I attempt to manually call the method right now:
```ExecuteEvents.Execute(gameObject, new PointerEventData(EventSystem.current), ExecuteEvents.endDragHandler);
hard viper
#

you aren’t setting anything here

silk portal
#

meaning there is some way to add some details to PointerEventData, right?

small schooner
silk portal
#

all I want is to call my OnEndDrag manually

small schooner
#

just do it

silk portal
#

I'm doing it

small schooner
#

you can

silk portal
#

there is nothing returned on raycast

#

exactly same object being moved as it was with regular drag, exactly same objects "under" it

small schooner
#

You can just call the Interface method you have in code manually

silk portal
#

how exactly do you mean? can't say I understand this stuff too well

currently I have
ExecuteEvents.Execute(gameObject, new PointerEventData(EventSystem.current), ExecuteEvents.endDragHandler);

as I can't seem to just call
IEndDragHandler.OnEndDrag(new PointerEventData(EventSystem.current));
An object reference is required for the non-static field, method, or property 'IEndDragHandler.OnEndDrag(PointerEventData)'

small schooner
silk portal
#

well the thing is I don't have OnBegin to get eventData from, I'm spawning object under cursor and trying to call OnEnd straight up when I press mouse button

#

not sure what the correct way to input PointerEventData is

#

ah wait... I removed "IDragHandler." from the method name

small schooner
#

why do you want to call OnEnd event when you press mouse button it sounds wrong

silk portal
#

well I have an inventory with item stack
with regular drag and drop I can move it from slot to slot

but I also have a split feature where part of the stack is kept in current slot and other half spawned under cursor to drop to new slot afterwards

#

I can spawn the object, move it with my cursor, but when trying to use same OnEndDrag method, I can't see anything with raycast

#

alternative I guess is creating new method and try fully manual raycast

small schooner
#

I usually dont even use any info from PointerEventData class I just need to know when we complete the drag or begin the drag the rest things I just do with custom code for example in EndDrag I can check position of cursor and put item inside cell in this position.

silk portal
#

yeah sounds reasonable, think I'll have to do the same
was hoping to save some time using existing method etc, but was pretty wrong 😄

#

thanks for sharing your thoughts

if I generate a mesh via code and I have 2 vertecies at the exact same coordinates
does this cause performance issues on a large scale or is it just the triangel that needs render time.

narrow summit
#

System.Runtime.Loader is this namespace not available in unity? Specifically AssemblyLoadContext

#

do I have to get it via nuget only?

heady iris
#

Now, if those two vertices are part of the same triangle, then that’s bad geometry

#

It’ll waste a surprising amount of time (the gpu has to draw a 2x2 block of pixels, even for an extremely tiny triangle)

peak peak
#

it's like the Unity plane

#

but a different shape

heady iris
#

If two triangles share vertices, you get "smooth shading": the normal vector blends gradually as you go from one triangle to the other

#

If each triangle has its own vertices, you get "flag shading"; the normal vector abruptly changes

#

it's very standard to do the latter

peak peak
#

ah now I get it so if i where to connect them it would be shaded like a ball like the shade smooth option in Blender

heady iris
#

Right.

#

In that case, you'd need to assign the same vertex to multiple triangles

I'm having trouble implementing air control for my jumping. I store the player velocity at the moment of the jump. and if I just use that for the movement during the jump the jump is predetermined. I'd like to introduce a little air control so I tried this: _velocity = Vector3.Lerp(desiredVelocity, _jumpDirectionVelocity, 0.3f); but it's not behaving as I expected. The moment I apply input opposite to the original direction the player stops mid air and starts falling straight down.
this is closer to what I want:
_velocity = Vector3.Lerp(desiredVelocity * 0.3f, _jumpDirectionVelocity, 0.5f);
but it has a drawback of limiting the original jumpDirectionVelocity.

leaden ice
#

It's also unclear when and how often you're calling it

#

MoveTowards is probably more likely the function you want though

tawdry jasper
#

So jumpDirectionVelocity never changes during the jump, and in update on every frame I want to allow, some air control. I know my initial approach was wrong, but I was thinking of Vector3.Lerp as a way to "mix" a 0.3 of the input * speed and 0.7 of the initial jump velocity.

cosmic rain
tawdry jasper
cosmic rain
#

I see. Well, in this case you should probably use proper lerping. Change the third parameter from 0 to 1 over time.

tawdry jasper
#

I'm trying to write out what I want exactly: 1) just use jumpVelocity when input is zero. 2) use jumpVelocity when input magnitude is 1, but it exactly aligns with the original jump velocity 3) "slow down" the jump velocity by some factor when they don't align. Now that I wrote that I think I want to scale jump velocity by some variation of the dotproduct between normalized input and jump?

cosmic rain
tawdry jasper
#

Tried this:

                float alignment = Vector3.Dot(targetDirection.normalized, _jumpDirectionVelocity.normalized);
                float lerpFactor = Mathf.Clamp01(1f - alignment * 0.3f);

                _velocity = Vector3.Lerp(_jumpDirectionVelocity, desiredVelocity, lerpFactor);

it looks like what I want, (and works for the no input, and input aligned with original jump, but the aircontrol is completely broken, I can actually move backwards beyond where I started the jump)

tawdry jasper
cosmic rain
cosmic rain
#

Ah, I see, it can be less

#

Between 0 and 1

tawdry jasper
#

right, so good call about 1-alignment, I now tried this:

                float lerpFactor = Mathf.Clamp01(1f + alignment * 0.3f);
                _velocity = Vector3.Lerp(desiredVelocity, _jumpDirectionVelocity, lerpFactor);

and it's aaaalmost perfect. it does exactly what I wanted in terms of inputing a direction aligned with original jump, and inputing directly oppossed to it.

quartz folio
#

Unity's Lerp is clamped btw, so your clamp is doing nothing

tawdry jasper
#

but the problem is dotproduct is 0 when the direction is perpendicular. So if I jump directly forward and inputing left or right the alignment is 0 and I can slow down the jump like I wanted but I can't actually control left or right...

#

I think I need to give up on the idea that this can just be accomplished with a single lerp. I'll keep this for the jump speed which is perfect, and use the lerpFactor to additionally add a "rotate towards" maybe?

#

rotate towards is working.

unfortunately this only works as long as I had an initial direction, if I jump standing, I suddenly have full air control 😦 I need to get some sleep, thanks all for hearing me out and suggestions

#

(that was an unrelated bug, it's all good! now I should give this for someone else to try, or play some more mario for research 🙂

If I have a vector2 array that defines a closed shape (where the first item connects to the second and so on, with the final item connecting to the first) how would I detect if a given position is inside the bounds of the shape?

yep

I suppose you could just create a polygon collider and then do a physics query with it.

I'd break the object into triangles and check the point in each triangle

Using an initial simple shape test first though to save checks

There are plenty algorithms that can do it, Google will bring up a few.

Easiest is just drawing any line across the point and then counting intersections.

I mean at worst I could just use an arbitrary point at like 600, 700

From wiki.

dusk apex
#

We don't know anything about the shape. Further context is necessary.

calm talon
chilly surge
#

But for an overview of the algorithm, to test that if point (x, y) is inside of a polygon, test all edges of the polygon and count how many edges intersect with line (x, y) - (infinity, y), if the count is even the point is outside, otherwise inside.

#

You can pick any line really, but a horizontal or vertical line makes the test simpler.

Hey all, need some help, not sure if this specific question belongs in beginner or here so I'm goin here 😅

I'm trying to take the combined rot+pos velocity of an object and compare to a min/max value, get the percentage within that range, then apply that percentage to another range to calculate something

#

I did find an answer on google, but I'm struggling to imagine how I'd apply the idea of minimum and maximums to it

#

e.g. if the velocity is greater than the max, it should only return 100%

dusk apex
#

I'm assuming you meant torque with rotation but position isn't a rate.

worn stirrup
#

🤔 I guess you're right

#

I definitely am doing an incorrect pos vel since I'm not calculating a direction vector

#

oh wait derp I'm not useing the rot, sorry

#

Im' using rb's velocity 🤦

# 
            float curVelocity = rb.velocity.magnitude;

            float totalVelocity = (curAngularVelocity + curAngularVelocity + curVelocity) / 3;

            float calculatedVelocity = (totalVelocity - minReqVel) / (maxReqVel - minReqVel) * 100;

            curDamage = (maxDamage - minDamage) * calculatedVelocity / 100 + minDamage;```
#

the / 3 is more or less me making up the idea that angular velocity sounds more important to a weapon than velocity lol

dusk apex
#

Your line is a bit differentcs float calculatedVelocity = (totalVelocity - minReqVel) / (maxReqVel - minReqVel) * 100; Saw something else

worn stirrup
#

I'm not exactly seeing what's different 🤔

#

(Total - min) / (max - min) * 100, looks the same to me?

chilly surge
#

That sounds like you are trying to remap a value from one range to another range?

worn stirrup
#

That sounds like a googleable phrase lol- yeah that sounds right

chilly surge
#

You can simply do an unlerp then lerp.

#

Or if you have Unity.Mathematics there’s math.remap() directly.

#

The algorithm given by that stack overflow answer is basically just unlerp then lerp.

woeful narwhal
#

I know when changing the value of a scriptable object during playtime changes it in the editor but not in the export but can you still use them for storing data during playtime? like could if i change the value will it still be changed a frame later?

dusk apex

#

Unfortunately don't have remap, just checked that e.e

chilly surge
#

It’s only in that package.

woeful narwhal
dusk apex

But there’s unlerp and lerp methods in Mathf anyways.

woeful narwhal
woeful narwhal
# dusk apex I didn't catch that.

so if i update a transform value in a scription object (SO) that i have a reference to. if another object also has a reference to that SO the transform in that SO will also be changed

#

does that make sense

#

sorry

dusk apex
#

As long as the SO is being used, access to the SO would be correct. If you load a new scene and objects in the new scene attempt to use the SO, they'll be given the default values again.

woeful narwhal
#

alright perfect

#

once ive created the system ill export a build just to check

#

thanks for the help

dusk apex
#

I'd advise against mutable SOs though.

woeful narwhal
#

what would you use instead?

dusk apex
#

Singleton manager etc

woeful narwhal
#

but the system im creating needs to keep track of multiple characters and their positions. would i use a dictionary instead, assigning a unique string code to each character and then allowing c# events to change the values?

dusk apex
woeful narwhal

yeah mb. ill figure something out. thanks for the help

My apologies for the stupid question but Google isn't helping (perhaps because I can't explain it well).

#

Is it possible to have Events with parameters from the script to send to the receiver?

soft shard
# flat abyss Is it possible to have Events with parameters *from* the script to send to the r...

Yes? (If I am understanding what you are asking correctly) If your event type has params, you can pass data through those in Script A, for example:

public System.Action<int> someEvent;

void SomeFuncInScriptA() {someEvent?.Invoke(25);} //SrriptA would invoke the event, in this case, the event type is a "System.Action" with 1 "int" param

void SomeFuncInScriptB(int someValue) {...} //this would be subsribed/unsubscribed from ScriptA.someEvent, because the event type is a int param, the func using it also needs the same param
flat abyss

Alright I think I can still work with this. Thanks a lot, fam

You guys got any tips on how to communicate data across domains? For a simple example.

Player taking damage and then that being updated in the UI (health bar)
Preferably you'd want the UI to not even know whose HP it's representing, just that it's representing some fractional value.
Player should also not concern itself with directly updating the UI.

Event bus

wicked scroll
# dawn nebula You guys got any tips on how to communicate data across domains? For a simple ex...

Well broadly, I build the game 'core' so that it can run without any UI, just a game state with actions to change it. And then to see stuff, there are a bunch of Views which can query that game state and transform/render it into the scene in whatever way makes sense (e.g. the player view is mostly managing one complex GameObject, whereas maybe the enemies are simple enough that they are all managed by one view. Whatever you need for the use case).

More specifically:

  1. I'm sure some people will disagree, but I think it's fine to naively update your views every frame until you run into a case where that actually matters. Unity is going to render a frame anyway and most of those updates should be pretty light. It's also pretty easy to optimize specific views with diffing or events later if you need them to update less frequently.
  2. I build scene objects as 'controlled' components which are intended to be controlled from outside. So the healthbar component doesn't know what it's displaying, instead there is a view which is responsible for querying and feeding the correct data into that healthbar.
west lotus
#

My personal opinion is to skip the whole model view approach. I see nothing wrong with the healthbar component directly subscribing to a OnHealthChanged event

wicked scroll
#

i don't like having to manage any subscriptions or references between gameobjects

#

or debugging stuff that deals with event bus execution orders

#

but it's totally a valid approach

dawn nebula
# west lotus Event bus

I'm also a fan of EventBuses. I guess my main issue is that when it comes to passing game state downward, shit is peachy. Get your state from save, pass it into your managers, check state of managers to save current state if needed.

It's passing state changes "up" that's always tougher. For example collecting an item in an level. That item needed to communicate to the inventory manager, once it's been collected, that some specific ability should be unlocked.

#

I imagine that this is where the EventBus would shine?

#

Just have the item toss some "ItemCollected" event with a specific item ID.

wicked scroll
#

yeah, though my solution is to basically eliminate any 'up' which feels preferable to me 😄

dawn nebula
wicked scroll
#

i think if your game is made up of 'global' events (like item colleted), it makes more sense to build around those actions and listen for them rather than doing that indirectly with events

wicked scroll
#

so objects down low don't do much input collecting

#

i guess the exception is like, if you have a button in a ui, but in that case i pass down a closure so that those components can remain dumb

#

and ultimately that button is just requesting that an action be enqueued, which is 'up' communication, but since all actions are processed through the same place, it feels more like making a request to something 'outside' the tree, if that makes sense

#

the scene is its own thing and it does whatever it wants, then can make requests to the 'core game' in one way, which is asking to enqueue actions or reactions, so they feel more parallel to me than stacked, i guess

dawn nebula
wicked scroll
#

mostly they are built in the top level view and triggered from the player doing stuff

#

e.g. there's an input layer which keeps track of which clikable the player is hovering and then a view with an onclick handler which reads that and builds a 'SelectThingAction(ThingID)' or whatever, and sends a request to enqueue that to the 'core game' (which is basically a wrapper around the gamestate which can execute actions to change it)

#

and then other systems can listen for SelectThingAction if they want and enqueue reactions to it or do some immediate thing

#

which for SelectThingAction is only useful for like, playing a sound effect

#

but for CollectItem could implement all the actual collecting logic if you wanted to

#

e.g. my CollectItem action would probably do nothing other than update the state by adding that item's ID to a set of collected items, and there would be other systems which would react to that action to implement actual mechanics

dawn nebula
wicked scroll
#

yep! but you don't have to write any events or subscribe to anything other than 'an action is happening'

#

your actions are automatically events

#

except you can pass them around and do stuff with them in a way that is tricky with c# events

dawn nebula
#

Wait is this not just the Command Pattern?

wicked scroll
#

it is

#

CQRS, more specifically maybe

dawn nebula
#

How do all your different action generating components get access to that queue?

#

Queue, List, whatever they're collected in

wicked scroll
#

typically though i think commands are supposed to be self contained executables though, whereas mine are often more like events in that the command itself doesnt' do much, and other systems are reponsible for 'game logic'

Once upon a time I too wanted to learn about how CCGs were put together, and that was the start of The Rabbit Hole.

wicked scroll
#

well something something how deep the rabbit hole goes?

dawn nebula
#

I don't agree completely with all the things in that article. String-based events are indeed gross for most other projects.

#

But there were a lot of GOOD concepts in there.

#

At the end of the day though that IS an event bus 😛

#

It's just you're delaying event execution a bit.

wicked scroll
#

yeah it is, but not in the sense that anyone ever uses it

thin aurora

The fact they use #region is already enough proof to me it's a bad article

thin aurora
#

Nah I can't

#

I need to vent my frustration

dawn nebula
#

do not disrespect my bro LiquidFire 2017

wicked scroll
#

i feel like it makes more sense to be like 'there is one event: something is happening, and things can subsribe to that' and then let my actual actions be the events

#

instead of defining and subscribing to every event individually, and also they can't have any 'built in logic' like actions can

#

feels like a much better path to the same place to me

thin aurora
#

I know I am going completely off topic but the code in that article is genuinely horrible

dawn nebula
dawn nebula
wicked scroll
#

at least for the kind of games i make -- i recognize that if you are building somethere where there are a lot of different inputs from the scene or physics stuff going on or whatever, maybe you really do want all your objects talking back and forth through this event bus...but i would only do it if i really needed to

dawn nebula
#

Covers a lot of what you actually do need for a CCG.

thin aurora
#

Sure it explains how to do it but they could have spend a minute thinking of proper conventions

#

They seem to violate every single one

#

And to be honest it's not even a good solution to begin with

wicked scroll
thin aurora
#

Iterating an IEnumerator like this is something you should not have to do

dawn nebula
wicked scroll
#

you just end up solving a lot of unnecessary problems, and, more importantly, having a lot of unnecessary code

#

but maybe that's better cause it's more robust and extensible, what do i know

wicked scroll
#

that is the whole idea -- you can drive the actions manually

#

you get to decide when the thing happens and how

#

but you don't have to, you can also just not attach any viewers and your game will run perfectly fine, just with everything happening instantly (very handy)

thin aurora
#

I'm not missing the point, I understand the problem it solves. But it's a very bad way of solving the issue

wicked scroll
#

oh nice, how would you solve it?

#

this is by far the best solution i've found

thin aurora
#

Oh this wasn't an invitation to explain the better way to do it, I just read the article and give my opinion on that solution

#

I'm totally fine with explaining why I think it's bad but that's not the point of this channel 🙃

wicked scroll
#

or do you mean you just don't feel like sharing?

thin aurora
#

It's bad, and there's definitely better ways, I just didn't imply I was going to write this, nor that I wanted to

wicked scroll
#

ok cool well thanks for stopping by

thin aurora
#

As I said, I would love to give my reasons on why it is bad, considering there's not much to an opinion without an actual reason, but I'm not solving it

#

But this is not related to the channel. If you think it's good by all means stick to it, but I feel it would be valued to atleast point out this is probably not a very good idea

dawn nebula
thin aurora
#

And this is getting out of hand anyway 😎

wicked scroll
#

but you do you

#

That's fine, I wasn't here to convince

wicked scroll
#

not to convince, not to help...what are you here for?

dawn nebula
#

Let's relax.

thin aurora
#

Let's continue using the channel for what it's meant for instead of back-and-forthing

dawn nebula
#

We're spinning in anger circles. He can say something is bad and not give an alternative. It's fine.

wicked scroll
#

haha no anger circles here, they sure can

dawn nebula
#

If anything though, I do agree that IEnumerators are not needed for this.

#

You can get a start/stop behaviour without them.

wicked scroll
#

it just makes it easier to coordinate a bunch of animations

#

and run them at whatever rate you want

dawn nebula
#

True but I personally wouldn't even tie animations in.

wicked scroll
#

those are just fun advantages though, really it's about wanting to both be able to specifically coordinate visuals for particular actions, but also not have to do that

dawn nebula
#

Let the thing resolve, and then queue up animations.

#

The game state gets solved in like a frame or two.

#

And then anims just play out.

#

I think this was my version of the ActionManager.

    public class ActionManager

yeah you can do that as well

#

in my case it was useful to have each action resolve as it was happening so that i could pick up intermediate state changes without having to build a way to simulate all the reactions

a better architecture might not have that problem, but anything event based that i can think of would

I have a scriptable object that represents my game cards,
And at the moment I have an array of GameObjects representing the effects attached to this card.
But that means I'm supposed to create a script that represents the effect (which inherits from a static CardEffect class), attach it to a GameObject and make it a Prefab so I can attach it to the ScriptableObject?
That sounds very redundant, is there a way to directly put the script in the Array ? Or can someone recommend me another method ?

gray thunder
#

@tacit dawn You assign a gameObject inside ur SO? Or the other way arround?

tacit dawn
#

I assign the GameObject in my SO for now

gray thunder
#

Why not the other way around

tacit dawn
#

Well because I have a script that « create the card » from the SO card
So this script takes all the information from the SO card (type, stats, effect, illustration …) and instantiates the « real » card on the board

#

So I wanted the SO card to have the ref to the effects so that it could be passed to the CardCreator script

Why can't I convert itemDroppedOnInvArgs to draggedItem with dynamic as Argument?
Is there a way to create a draggedItem as event args which can hold different arguments (int or Vector2Int)?

private ItemInvSlotEventArgs<dynamic> draggedItem;

  }
}

private void OnItemDragBegin<TPosition>(
    object sender, ItemInvSlotEventArgs<TPosition> itemDroppedOnInvArgs) {
  draggedItem = itemDroppedOnInvArgs;  // Error: Cannot convert to dynamic
}
hard viper
#

maybe it’s because the type argument is dynamic, not the type itself

leaden ice
#

I question your use case here but just using object and casting is always an option

hard viper
#

i generally question the choice of dynamic vs a generic argument with a constraint

leaden ice
#

I also really question the use of the EventArgs pattern in Unity anyway, since it's an unnecessary source of GC allocation

hard viper
#

to the immediate question, I would maybe start with ItemSlotEventArgs<T> : ItemSlotEventArgs,

#

and avoid the dynamic argument altogether

#

but i agree with praetor, that you probably want to think more about the structure before you code anything up

Good morning friends, I have a problem. When my enemy uses flip to change direction, his colliders don't change either. How can I fix this?

leaden ice

If you want to rotate all that stuff, actually rotate the object 180 degrees on the y axis for example, rather than using the flipX checkbox on the SpriteRenderer

unborn shard
#

I'm a beginner hahaha, I don't know how to solve this

leaden ice
#

I just told you how to

unborn shard
#

thanks

round violet
#

i got a base class.

i have 2 methods :
Connect() - calls DoStuff
DoStuff

Connect() will never be overrided in children classes
DoStuff will be override in each children class

to make a override in a child class, i simply have to write DoStuff, and then when the parent will call DoStuff it will call the child override ?

leaden ice
#

meaning DoStuff needs to be abstract or virtual and the child class needs to use the override keyword when implementing it

round violet
#

if i have a instance of a child class, and try calling Connect(), it will call it in the "parent" class
but then Connect() will have to call DoStuff(), will it call it in the child ?

heady iris
#

Which non-virtual method you call is figured out at compile-time.

A myVar = new B();
myVar.Work();

If Work is non-virtual, this will always call A's Work method.

#

A virtual method is figured out at run-time

round violet
#

im my head i got the same logic as UE does in BP

leaden ice
heady iris
#

so if Work is virtual, this will call B's Work method

#

virtual methods use the run-time type. non-virtual methods use the compile-time type

round violet
#

so all methods in parent that will be overrided has to be virtual ?

heady iris
#

Correct. You cannot override a non-virtual method

leaden ice
quaint rock
#

you can only override virtual or abstract methods

round violet
#

and those methods in child has to be with the keyword override

leaden ice
#

yes

quaint rock
#

if you try to override a regular method it will not compile

heady iris
#

yeah, abstract methods are virtual, by definiiton

#

You can still define a method that "hides" a parent method by using the new keyword

heady iris
#

I've never really done that.

round violet
#

and for not overrided methods ?

when you create a child class, all not overrided methods "exists" in the child class, but they dont show in the cs file

#

right ?

heady iris
#

A class inherits all members from its parent.

round violet
#

why virtual methods cant be private

heady iris
#

because that'd be pointless

round violet
#

child inherits private stuff to so why bother

quaint rock
#

because private means it cant be accessed by the child class

#

use protected instead

heady iris
#

A private method cannot be seen by anything outside of the declaring type

round violet
#

im dumb

#

forgot that mb

heady iris
#

critically, this means that there's no way for any other method to override it

#

so you'd never have a situation where the method you call depends on the runtime type

quaint rock
#

private only class its defined in can see it, protected can be seen where its defined and extending classes

#

public everything can see it

round violet
#

how would i create a prefab variant
and override stuff for the class inside

heady iris
#

those are two unrelated concepts

round violet
#

do i have to replace my parent script with child ?

quaint rock
#

unrelated concepts

heady iris
#

Oh, I see what you're getting at though

#

and this is actually a problem I've had too

quaint rock
#

but just replace the script with a other that extends from the same base

round violet
#

in UE i would create a child BP, then open this BP and override what i want

how does Unity handle this ?

heady iris
#

I've done this through composition, rather than inheritance

leaden ice
#

Yeah unity favors composition over inheritance

heady iris
round violet
#

so composition

#

ill have to see how this works

heady iris
#

in my game, I have an Entry component that's used anywhere I want to display an editable value

quaint rock
#

also keep in mind there is no need for big complicated classes that handle many things

heady iris
#

I then have other components that implement specific kinds of entries

#

like ChoiceEntry

quaint rock
#

when you can have more basic one use components you all put on 1 object

heady iris
#

This is composition-based.

#

The base prefab has an Entry, and each variant has another component, like ChoiceEntry

round violet
#

instead of creating a child class i think ill make additive components

heady iris
#

This is a bit more awkward than just having ChoiceEntry derive from Entry

#

but it works out pretty well

# 
    public void Setup(IChoiceItem choiceItem)
    {
        this.choiceItem = choiceItem;

        entry.Setup(choiceItem);
        // more stuff
    }
#

I setup the ChoiceEntry, and it setups the Entry

round violet
#

because if i dont the base class wont know what methods it can call inside

round violet
heady iris
#

this is from ChoiceEntry.cs

#

I call Setup right after instantiation

#

ChoiceEntry holds a reference to Entry, and it calls Setup on the Entry as part of its setup process

#

It's kind of like a constructor.

round violet
#

so ChoiceEntry is the additive script that changes the "base class", Entry

heady iris
#

Right.

#

Entry has some logic for things like showing a description when you hover over the entry

#

and the Entry prefab includes the label and a space to put stuff

#

ChoiceEntry includes the actual UI for a choice setting

image.png
round violet
#

i think i have in mind my new structure, ill try this out

heady iris
#

(man, the bloom looks really nice in the scene view...)

#

it's an overlay UI, so post-processing doesn't touch it

#

FloatEntry has its own stuff

image.png
#

that text looks hideous in the prefab view

#

This has been really nice. I originally had FloatSettingEntry and FloatConfigEntry and FloatWhateverEntry

heady iris
#

I mostly use it for game-wide settings and per-entity configs, but I can also just make a FloatValue anywhere I want and present it to the player with a FloatEntry

round violet
#

i combined additive components with inheritance and i got perfectly what i wanted

arctic silo
#

how i can make player can go trough enemy's collider when in dashing state? (while tilemap's collider is still stopping player)

leaden ice
heady iris
#

you can also set a collider to ignore collisions with a specific layer

arctic silo
#

thanks

heady iris
#

which overrules the collision matrix

arctic silo
leaden ice
#

oh that works too i suppose

unique delta
#

if i instantiate an object and move it like a bullet. The bullet is moving laggy. I can do something about it?

quaint rock
#

it moving laggy is not because of how its instantiated

unique delta
#

it could be from some settings of the rigidbody2d of the object?

leaden ice
#

if you don't have interpolation turned on, it will not appear to move smoothly, yes

#

make sure interpolation is turned on on the Rigidbody2D

round violet
#

to make a fan "pushing" object in its radius, i think of using a collider and OnTriggerStay and translating/add rigiobdy force/using MovePosition on all colliders detected

is there a better way ?

unique delta
round violet
# 
 private void OnTriggerStay(Collider other)
 {
     if (active && other.tag == "Player")
     {
         Debug.Log("pushing : "+ other.name);
         Rigidbody rigidbody = other.gameObject.GetComponent<Rigidbody>();

         rigidbody.MovePosition(rigidbody.transform.position + new Vector3(0, 1, 0) * Time.deltaTime * pushingSpeed) ;
     }
 }

Player is printed when going in, i get no errors so the rb is found

leaden ice
#

Also other.gameObject.GetComponent<Rigidbody>(); can just be other.GetComponent<Rigidbody>(); as well

I want to make a player attack move in a 2d platformer game, i already have a extensive movement script with about 500 lines of code. Is it good practice to seperate movement and attack in this case? My players ability to perform certain attacks and animations do depend on the movement script.

round violet
#

but i wonder why moveposition wont work

#

maybe the deltatime

heady iris
#

MovePosition might not apply a force correctly

#

It just tries to put the rigidbody somewhere (respecting colliders along the way)

#

it's not like you're actually pushing the rigidbody

turbid river
#

I have a question

#

im making a simple game,
how do I know if I'm putting too work in a single frame (update)
like how much work can one frame really accomplish(ik it depends on hardware but generally)

heady iris
#

your game will run slowly if you're doing too much

#

it's hard to say anything more than that

#

use the profiler to measure how long your code is taking to run

turbid river
#

and what are the solutions for that?

heady iris
#

do less work per frame

#

again, this is super vague

#

you're basically asking "How do I make my game run faster?"

#

Maybe you can do expensive calculations infrequetly and just re-use the results between runs

#

or maybe you can do time-slicing so that you only work with a fraction of your data per frame

#

or you can move work into Bursted code that runs much faster

turbid river
#

very interesting
I still haven't gotten to that problem but sometimes I look at my code and I see loops and while loops and I wonder "how is all this being done every frame"

heady iris
#

hah, I've certainly thought about that

#

but..computers are bloody fast!

visual badger
#

Hi guys do you know why I get this choppy effect on my UI:

heady iris
#

You can turn on Deep Profile in the profiler to get a very detailed breakdown of what's running every frame

#

Note that this will:

  • make the game run really slowly
  • make cheap functions disproportionately slow
visual badger
#

I have the canvas on screen space camera

#

btw

heady iris
#

Deep Profile adds a constant cost to each function call, pretty much

heady iris
#

it's a really obnoxious problem -- you get bad motion vectors on the UI

visual badger
#

ye

heady iris
visual badger
#

okok

#

ty

heady iris

hello peeps! what approach should I take to making child objects static and components of a parent object?

with the following example I want to mention that each child should not be individually simulated, it's just a part of the larger object, (the parent)

->parent
-->child1
-->child2

#

ideally I don't want to strip their rigidbodies, since those will still be utilized for hitboxes, and will come into play later when these objects no longer connect and exist on their own

#

I have done lots of looking on line and tried chatGPT but couldn't find how I can do this. it seems fairly simple though which makes me think maybe its a built in feature in unity that I don't know of?

somber nacelle
#

each child should not be individually simulated
I don't want to strip their rigidbodies
pick one

severe sable
#

so there's no grey area?

#

lets go with I don't want to strip rigidbodies

little meadow
#

you can make them kinematic, no?

severe sable
#

what are my options

somber nacelle
#

you could make the rigidbody kinematic but that has other implications, like not properly colliding with objects because outside forces do not affect them

severe sable
#

ok, so what would you suggest?

somber nacelle
#

or you could just not give them a rigidbody until they are disconnected from the parent

severe sable
#

box, you gave me a choice between 2 options so lets go with keeping rigidbodies and allowing them all to be simulated, how can I make them move as a whole & what can I do to prevent this from being too intensive

#

if its very intensive I don't really care honestly, this is a hobby project I am doing to learn :)

#

part of learning is making mistakes but I've made far too many on this concept and am looking for help from an expert like yourself

somber nacelle
severe sable
#

🙄

somber nacelle
#

cool so i guess i'm just not going to help you then. good luck 👍

#

i didn't just say those things for shits and giggles, you know

severe sable
#

no need to be rude?

somber nacelle
#

if you want the objects to have rigidbodies but you also want them to not be individually controlled by those rigidbodies and instead be controlled by the parent then they will have to be kinematic. otherwise they shouldn't have rigidbodies

spring heart
#

Boxfriend did you ever use navmesh?

somber nacelle
#

i have, but if you have a question then you should just ask it instead of asking to ask

severe sable
severe sable
somber nacelle
#

then your options if you refuse to remove the rigidbody and refuse to make them kinematic are to simply move all of the individual pieces manually so that they move with the parent. or you can use joints but that does not prevent their rigidbodies from acting on them and they may not behave the way you are expecting

#

so basically, do the things i suggested that you for some reason do not want to do. or do it the hard way that will arguably be worse

severe sable
#

The reasoning is complicated it's based on the type of game I'm trying to make

somber nacelle
#

for which you have not provided any info. so my answer stands

severe sable
#

do you know terratech/robocraft/stormworks? it's a ship builder game

#

connect blocks to build somthing and drive/fly it around

hard viper
#

rigidbody allows an object to interface with the physics system (be moved by physics system, interact with colliders, give collision callbacks, get contacts).

A rigidbody being not simulated means none of these happen. It is not simulated, so it is like the rigidbody effectively does not exist.

severe sable
#

closer to robocraft, since in that one individual parts can be shot off and each block is simulated in a hitbox way

somber nacelle
severe sable
hard viper
#

if an object does not need to separatley interface with the physics system (eg the features mentioned above), it does not need a rigidbody.

severe sable
somber nacelle
#

your projectiles can have a rigidbody to provide OnCollision messages, and/or the parent object can have one. the individual child objects do not need them

#

they just need colliders

hard viper
#

rigidbody is only really needed to make interactions between things with colliders.

#

if colliders are not involved, there is no reason to have a rigidbody at all

#

simulated or otherwise

severe sable
#

so if I understand correctly, a rigidbodies transform also won't matter if it doesn't cover the entire ship in the editor correct? since it's just a vessel to apply force to?

#

besides center of mass*

hard viper
#

a rigidbody is an entity handled by the physics system that then couples positional information to the transform, and sends messages to scripts on the object for collisions

somber nacelle
#

the rigidbody itself does not have volume. that's what colliders are for and all child colliders of a rigidbody parent will become part of that rigidbody's compound collider

hard viper
#

the rigidbody defines a single unit/object in a physics sim

severe sable
#

very interesting, that was my next question, how could I add all my colliders togeather? is a compound collider done automatically by the engine? or is it something I need to setup manually?

hard viper
#

composite collider combines many colliders into one collider

severe sable
#

it's not done during runtime though is it? I would have to manually set that up?

somber nacelle
spring heart
#

@somber nacelle So I'm using vuforia for area targets and I want to use navmesh to create a mesh for the floor so I can then guide the person from one point to the other. The whole idea is to create a indoor navigation for our offices but the tutorials and documentation on the vuforia site is severely outdated.

hard viper
#

if you have two squares next to each other, a composite collider would make a rectangle

#

but that is more of an optimization of the shape

#

if you have two squares on an object, that rigidbody will count it as all one thing

severe sable
hard viper
#

one thing with multiple shapes

somber nacelle
hard viper
#

i would probably try making each child object have a separate kinematic rigibody, and apply no movement to it. Parent rigidbody would be the one to actually move

#

this way each child object can receive separate messages

severe sable
#

seperate messages? like events?

#

or physics messages?

hard viper
#

otherwise parent script needs to check each collision, and sift through all colliders to see which collider was hit

#

OnCollisionEnter is a message

#

collision callback

somber nacelle
#

eh making them all have kinematic bodies isn't entirely necessary. the OnCollision message will be sent to the rigidbody parent and that can dispatch the message to the individual child since the Collision parameter contains info on what was hit.

severe sable
somber nacelle
#

or if using OnTriggerEnter then the child objects will receive the message anyway

severe sable
hard viper
#

giving them all separate kinematic RBs is just a simple way to split the messages getting sent.
Of course, you can have just parent RB, it gets message, then checks dictionary of colliders to see which one is relevant.

severe sable
#

box, can this be done if we don't ues the kinematic rigidbodies?

hard viper
#

yes

#

it’s just a different approach

#

giving them kinematic RBs is simpler for code imo, because at this point idk how much you can handle in terms of programming

somber nacelle
hard viper
severe sable
#

ok, since I've noticed my codebase gets large fairly quick and I've been trying to stick to the single responsibility rule and such it would be best to not use a dictionary or list of colliders right?

hard viper
severe sable
#

decoupling* thats the other word

hard viper
#

decoupling is separate from single responsibility

severe sable
#

ok, thank you so much so far both of you <3 yall been great, I have to run for a minuite or 2 to next class and then I'll be back

hard viper
#

i am assuming that the script on the parent that moves the message along gets one responsibility (to forward collision callbacks to relevant child objects)

#

i would probably make it a simple script that just manages child objects

#

ie it’s job is to maintain a list of child objects, add new child obj, make sure the new child added is valid, remove child objects, expose a readonly list of the current parts/children, and pass collision callbacks to child objects

# hard viper ie it’s job is to maintain a list of child objects, add new child obj, make sure...

also one other question if you have a second, is using box colliders the best way to do attachment points? By attachment points I mean where the player can drag and click on to place the block they have currently selected
currently I am using 4 box colliders adjacent to my center of the Block and I have a script to manage them and enable/disable, it's not great as it can end up with many blocks on top of each other but it is working unlike any of my prior attempts

image.png
hard viper
#

colliders and UI are a bit different

#

colliders live in world space. the cursor lives in screen space

#

i would avoid using unique colliders in world space as hitboxes for your cursor to touch, as much as possible

#

if you want to make a menu, make a menu on the canvas, and find the point in screen space to know where it goes

#

but don’t start making trigger hitboxes etc in the world, to make UI objects in the world

Sounds like it's a list and you need to just clear the list

#

It's hard to tell from this snippet

knotty sun
#

exactly, it's still an anonymous method

#

what is this doing?
requirement.AddRequirementChangedListener

#

so they are adding Listeners?
so AddIfUnlockedAction is now a named method which you can unsubscribe

#

this all seem unbelievabley complex and convoluted

#

so really you need to reproduce the whole sorry structure to do the reverse to unsubscribe

hard viper
#

you know you can just make a collection of delegates, right?

knotty sun
#

so if you do that like this
requirement.AddRequirementChangedListener(AddIfUnlockedAction)
you should be ok

hard viper
#

or a collection of a struct that cotains a delegate + metadata to sort/etc

#

i’ll send you a simple class I wrote

# 
/// <summary>This is affectively an Action, where the inner implementation is
/// a list to allow lots of entries to be added more easily.</summary>
public class BigAction {
    private List<Action> actionList = new();
    /// <summary>Construct big delegate with capacity.</summary>
    public BigAction(int capacity = 16) => actionList = new(capacity);

    public int Count => actionList.Count;
    public void Add(Action action) => actionList.Add(action);
    public void Remove(Action action) => actionList.Remove(action);
    public void Clear() => actionList.Clear();
    /// <summary>Invoke all the actions. Actions can be added to the delegate in the middle, but do not remove.</summary>
    public void Invoke() {
        for (int i = 0; i < actionList.Count; i++) actionList[i].Invoke();
    }
}```
#

FYI, when you += a ton of delegates, += and -= is super slow

#

I'm talking when you have a LOT of functions in a delegate

#

that’s why I made this class, but this class has similar machinery to what you are looking for

#

it just makes a list of Action, and allows you to Invoke all the actions in the list

#

just manage your delegates in a collection

#

i would use a slightly different class to be able to organize your actions with a struct or something

#

or separate lists of actions, or a dictionary of actions

#

what I wrote is simply equivalent to an action

#

but with a list implementation

#

you want to organize and control the flow and all that

#

that would require a List of a struct/tuple with your delegate, or a dictionary that leads to your delegate

#

you just need to program that extra step of organization that you want, basically

#

that said, I would expect that no matter what you write, you WILL have a function that is equivalent to every method in that class I sent

#

your data structure needs the ability to initialize, invoke, add, remove, clear, and check the current contents

#

this is a very basic collection implementation

Hello.
Do you guys think I can animate an object with an AnimationClip without using an Animator?

So far I've found that I can extract the curves of an animation with AnimationUtility. I could then Evaulate the curves individually but I don't know how to actually apply the floats I get from that. Using the curve bindings I can get the propertyName of the specific curve and that gives me strings like "m_LocalPosition.x". Problem is that this doesn't really help me unless I have a way to change a property based on a string somehow?

learn to write basic data structures. they will make your life much easier

#

they are usually very simple code. does not need to be complex.

#

should my players movement and attacking system be in the same class?

#

e.g. during a jump a down air side air up air attack can be performed, jump state is tracked in movement, attack input is tracked during attack. Merge these or seperate anyways?

rain minnow
lavish frigate
#

True. So should i also keep both attacking and movement state machines seperated?

im not audio expert so apologies for my stupidity
but what EXACTLY does GetSpectrumData do? i need a pitch detector (outside of unity) and found a perfect one FOR unity, but it uses some audiosource stuff and im not sure what to translate this into non unity stuff. i dont need to visualise anything though, i just need to print out what key an audio is playing in, thats all

#

It performs an FFT

#

a fast Fourier transform

#

there are lots of libraries for doing this

#

a Fourier transform takes a time-domain signal (e.g. amplitude over time) and gives you information about the frequencies that are present at each moment in time

#

OHHH so thats what it does

#

now im kinda unsure why it's a void, or like what am i getting from this?

chilly surge
stuck forum
#

that explains it

#

tho i dont understand how the data passed back into the array in the param

chilly surge
#

Pretty common that you pass a storage as parameter to a method and the method simply fills that storage, rather than the method returning a new storage which can potentially cause allocations. This way the caller can optimize and reuse the storage.

TIL thats possible

#

ty for the help!

plucky lance
#

what other yields can ienumerators do

#

for example WaitForEndOfFrame, WaitForSeconds

#

is there other ones?

Its probably something very obvious, but does anyone know what is causing the code to skip the if statements in my code?

    {
        SceneManager.LoadScene(SceneManager.GetActiveScene().name);
        highScore = PlayerPrefs.GetInt("highScore");
        Debug.Log(highScore);
        if (highScore > 0)
        {
            highScoreText.text = "No Scores Currently";
        }
        else if (highScore < 0)
        {
            highScoreText.text = "High Score: " + highScore.ToString();
        }
    }```
It gets the the debug.log and returns 2 but doesn't even run the first if, much less the second

put Debug.Log inside the if statements to see which one if any is running

Showing us the console logs would help as well

versed spade
#

And they should be satisfied! But they aren't! The logic is there, but the code isn't going there. Its hurts my brain

leaden ice
#

I bet you one of them is running and then maybe some other code is overwriting the text later or something

versed spade
#

The second one is def not running, had a log in it

Make sure to save your player prefs

Hey I am a computer science student, looking to get some experience. I do not need to be paid. just want a more put together team that wont disappear in a week. I am competent in C# and very confident I can do pretty much anything put in front of me given enough time. I have also taken AI courses in Uni so I would love to put some of that knowledge to the grind stone to learn and apply what I have learned in theory. the one area I do not know is the Unity Library. However, If that is all organized on there website I am sure that I can just look anything I need up to do what I need to do. Does anyone have any teams they know of looking for somone?
