or is there a better way?

#

You could also pay the instantiation cost up front with prewarmed object pools, at the cost of additional memory.

#

How do I make a gizmo visible permanently? I just started using gizmos for the first time and right now it only shows when I have the object with the script that has the gizmo selected

#

Does C# have something similar to a struct or a even a table?

leaden ice
#

Unclear what you mean by table. Are you talking about LUA tables? If so then yes, C# has Dictionaries

strange scarab
#

I'm actually looking for somthing like a 3D array

leaden ice
#

but that's not an associative array /table

#

you could also use a Dictionary with a 3D coordinate as the key and that would be similar, and better in sparse data situations

latent latch
#

better because you don't actually need to declare every index

strange scarab
#

I need to store data about x y z positions of voxels

#

because I need to loop through the data of cubes when being destroyed think teardown.

#

I've succesffully done it in roblox using tables lol but now I'm trying to do it in unity

latent latch
#

right, stick to a lookup table as you only need to store pivots

Okay thanks guys

loud vector
#

Any idea how to check for a GameOver in a game similar to Woodoku?

image.png
#

Do I need to check all possible combinaisons with the pieces that the player has?

leaden ice
#

how does the game end here?

loud vector
#

The game ends when the player dosent have any possible tiles to place his shapes.
The screenshot dosent cause a game over

leaden ice
#

Yes you'd presumably have a function that looks for a valid piece placement and if none are found, gameover

loud vector
#

Makes sense. Is there any hints or documentation on how to do this? Im guessing this is pretty niche

leaden ice
#

documentation? Wdym

quartz folio
#

It's completely dependent on the game

leaden ice
#

How or why would there be documentation on making this particular game?

#

Looks like a simple for loop

loud vector
#

I thought that this kind of game was pretty popular lol

leaden ice
#

there are only 81 possible positions any piece could be placed in. The first approach you can try is simply to check all 81 positions

leaden ice
loud vector
#

Yeah ofc

#

Anyway thanks for the help

Can I put a coroutine in its own class if I use things like ‘public ClassName className;’ and have access to variables within the declared class. I might not even need/shouldn’t attempt this but I’m trying to breakdown an issue into smaller parts and this is one avenue I’m exploring in the “think it out” stage.

It may not matter but I’m also noting, this coroutine contains a nested while loop which I have almost made stable(ish) by extracting and inverting the inner while loop to a method

leaden ice
# glass fossil Can I put a coroutine in its own class if I use things like ‘public ClassName cl...

This question is very vague and it's unclear exactly what you're asking. I'll respond with a few points about coroutines that might help you:

  • StartCoroutine itself can only be called on a MonoBehaviour instance, but can be called on that MonoBehviour instance from anywhere.
  • The actual IEnumerator-returning-function can be declared anywhere, it doesn't matter. All that matters is that when you call such a function it returns the IEnumerator and you can pass that IEnumerator object returned from any such function into any MonoBehaviour's StartCoroutine.

how can i make a gameobject rotate 360 degrees smoothly?

#

i want to use quaternion.slerp instead of lerp

leaden ice
tacit swan
#

ohhh that explains why the code wasn't working xd

#

so ig i have to use lerp right?

leaden ice
#

So what you actually want to do is Lerp a float between 0 and 360, and generate a quaternion from that

#

e.g.

float start = 0;
float end = 360;
float timer = 0;
while (timer < duration) {
  timer += Time.deltaTime;
  float angle = Mathf.Lerp(start, end, timer / duration);
  Quaternion rotation = Quaternion.Euler(0, angle, 0);
  transform.rotation = rotation;
  yield return null;
}```
tacit swan
#

i declared the start, end, timer in Start()

#

and am running the while in the Update()

#

did i do something wrong?

leaden ice
leaden ice
tacit swan
#

ohh

leaden ice
#

fixed

#

without waiting a frame in the loop, naturally the loop will be useless

tacit swan
#

yield return null waits for 1 frame right?

leaden ice
#

yes

#

this can also be done in Update but it wouldn't use a loop

tacit swan
#

ok nvm

#

just weird perception

#

tysm!

Hey, is there neat method for finding points inside closed spline?
Spline itself is posY const with local up vector allways being (0,1,0). I'm currently having to check upwards of few thousands points per spline with tens of splines, but with current crude implementation i'm having big issues with performance that scales very bad with multiple splines.

hey guys, I want to make a game like thief puzzle, so that I need to wrap a line renderer around an object by using raycast. However, when I drag very fast, my line go through the object. How can I solve this problem ?

I have a dedicated server build and am trying to connect with it by entering play mode in Unity Editor. I am getting an error about socket creation failing because only one usage of each socket address is normally permitted. Not sure where to ask about this

could someone help me debug this problem, ive been on it for a while but dont see whats wrong with it.
I have an inventory system but the first slot keeps getting overriden because it thinks the slot is null or empty.
heres my inventorymanager function:

public void AddItemToInventory(GameObject pickedUpObject)
    {
        // Check if the item to add is not null
        if (pickedUpObject != null)
        {
            // Get the Item component from the picked-up object
            Item itemToAdd = pickedUpObject.GetComponent<Item>();

            // Check if the itemToAdd is valid
            if (itemToAdd != null)
            {
                // Iterate through the inventory slots to find the first empty slot
                for (int i = 0; i < inventorySlots.Count; i++)
                {
                    InventorySlot slot = inventorySlots[i];

                    // Check if the slot is empty
                    if (slot.IsEmpty())
                    {
                        // Log the slot index where the item is added
                        Debug.Log("Added item to slot " + i);

                        // Add the item to the empty slot
                        slot.AddItem(itemToAdd);

                        // Update the UI to reflect the changes
                        slot.UpdateUI();

                        // Item added successfully, so return
                        return;
                    }
                }

                // If no empty slots are found, handle as needed (e.g., show a message)
                Debug.Log("Inventory is full or no matching slots.");
            }
            else
            {
                Debug.Log("Picked up object is not an item.");
            }
        }
    }

heres my other functions:

private Item currentItem; // The item currently stored in this slot

public bool IsEmpty()
    {
        return currentItem == null;
    }
#

I've already checked and the slots are seperated into their own boxes so its not like theres only 1 slot to go into, the index is telling me its only trying to enter the first box, and considering the first slot image keeps getting overriden, it tells me that the IsEmpty function is not working how it should

#

^ im going to bed... Ill be up in like 6 hours to keep workin xD

fervent furnace
#

why the code looks ai code...
btw log inventorySlot after add

InventorySlot slot = inventorySlots[i];
if (slot.IsEmpty()){
    Debug.Log("Added item to slot " + i);
    slot.AddItem(itemToAdd);
    slot.UpdateUI();
    log inventorySlots[i] data
    return;
}
#

i guess InventorySlot is struct

#

and the indexer is getter

#

ah, whether the indexer is getter or direct memory access doesnt matter

Hello. I have a little question. I am following GameDev.tv's 2D tutorials and I finished the delivery driver section. I learned a lot from them and I have a question. So, at the challenge where one of the guys told us to make the boosts and slows for the car, I made this:

    void OnTriggerEnter2D(Collider2D collision)
    {
        if(collision.tag == "Boost")
        {
            moveSpeed = boostSpeed;
        }
        if(collision.tag == "Slow")
        {
            moveSpeed = slowSpeed;
            collision.isTrigger = false;
        }
    }
}

But he made this:


    private void OnCollisionEnter2D(Collision2D collision)
    {
        moveSpeed = slowSpeed;
    }
    void OnTriggerEnter2D(Collider2D collision)
    {
        if(collision.tag == "Boost")
        {
            moveSpeed = boostSpeed;
        }
    }
}

I want to know if my method is faster to process or slower

knotty sun
#

tbh I dont think yours will work. Once you set isTrigger to false your method will not be called

vapid bluff
#

I have some buildings that have the tag, and it works as intended

fervent furnace
#

then your car is triggered collider?....

vapid bluff
#

yeah, something like that

#

and all I need to know if my method is faster or his (as in processing the data and frames and not making it laggy)

fervent furnace
#

The box collider on your car is not trigger…

vapid bluff
#

ok, I understand that

#

but I asked if how I wrote is faster or not

knotty sun
vapid bluff
fervent furnace
#

I have no idea why your ontriggerenter still be fired (maybe you have two colliders on your buildings)

vapid bluff
cosmic rain
knotty sun
#

if you are wondering are Trigger colliders more efficient than physics colliders then yes they are because there are much less physics calculations required

fervent furnace
#

Then if your car collide with the buildings again and the ontriggerenter wont be fired

vapid bluff
knotty sun
vapid bluff
#

and maybe idk how to explain

knotty sun
#

look, it's simple, if you hit something tagged slow the trigger is set to false which means only OnCollision events will fire, you do not have those

#

in the othe code he covers this by having both OnTrigger and OnCollision event handlers

vapid bluff
#

I made another video where I show that with what I wrote, it works as if I wrote the guy's solution

#

I know it may be a mistake and I am taking any criticism and adivce, I just wanted to know wich was faster (wich you answered, this video is to show you that it works as well as if I wrote the other example)

var results = Physics2D.LinecastAll(this.Hand.transform.position,

            {
                if (hit.collider is { gameObject : { layer: (int)Layers.Character } } or { gameObject : { layer: (int)Layers.SpecialLoseElement } })

Is there a way to stream an audio file when loading from resources folder?

I'm working on a modding support for my game and threat my "Default" game data as a mod, which is stored in the Resources folder.
I've managed to stream audio when loading from a persistent data path and it works like a charm.
But, when loading from resources the file loading causes a lag spike.

Or the approach with the Resources folder is plain wrong and there're better options?
Maybe Asset bundles/Addressables would be a better option?
But, I really want to keep it simple.

knotty sun
#

Resources will not work for modding support anyway, so stick to PersistentData

wanton wasp
#

Yeah, I just want to include the "Default" configuration for the game in the build.
Otherwise, the player would have to download it separately in order to play.

knotty sun
#

include it in StreamIngAssets

wanton wasp
#

Already tried, but could not load anything from it.
Will try it again.

knotty sun
#

which platform?

wanton wasp
#

Android

knotty sun
#

use UnityWebRequest to load from StreamingAssets on Android

#

you can even copy to PersistentData if you want

In the editor and windows build it worked fine

Oh...Yeah, just remembered, that jar is a zip.
And can't be accessed via IO.

I'm creating a Quest system and i want to serialize and save the data to disk. I'm having problems with serializing a List since having this structure:

[System.Serializable]
public struct QuestSave
{
    public List<Quest> Data;
}

gives this JSON as result: {"Data":[{}]}
I don't think the problem is about the Quest class, because since I'm using System Actions I thought that the problem were them and so wrote a custom serializing system for my system actions

Thats the entire code tho:

QuestSerializer.cs
QuestManager.cs
QuestData.cs

Is there a way to spherecast and ignore specific objects as well as layers? Lets say I'm controlling an enemy so I still want them to be on the "Enemy" layer but I don't want my spherecast to contact the specific enemy i'm controlling.

Is this possible or should I move the controlled enemy to a new layer such as "Controlled" or whantot.

in fact, it would be impossible as incrementing an integer only happens on the cpu register stack

@knotty sun thank you so much! That works like a charm

I did a bunch of benchmarking, and have some info on Physics2D

#
  1. .Distance is pretty optimized, and about 1 microsecond per call.
  2. rigidbody and collider2D Cast have similar cost.
  3. ContactFilter2D is super important. The cost of .Cast or .OverlapCollider is roughly proportional to the number of unfiltered colliders in the given area. So filtering makes the method actively much faster.
  4. Casting into a dense blob of colliders that are not filtered out by a query is expensive. Spreading out the same colliders (so some don’t get checked) makes it much cheaper.

ahhhhh mbmb misread it as spherecast without a layer param

hard viper
#

I have a singleton class that maintains a Hashset of tuples, for colliders that should ignore each other (oneway).

#

you could do that sort of thing, to filter out the result after the fact

#

Physics2D also has a SetIgnoreCollision or something to make two colliders just not acknowledge each other. You might be able to use a similar thing with Physics3D

can be done but you need to use reflection

so Unity cannot do it

if you want a serialized Action just use a UnityAction or UnityEvent instead

yes you can but then you have to do it all yourself, you cannot mix n match

knotty sun
#

most serialization systems use reflection which is a very poor way of doing it

maiden junco
#

I've seen that for serializing callbacks in general you have to still use reflection

#

UnityEvent, UnityAction, System.Action....

knotty sun
#

yep, very true if you want to serialize yourself, and even then it's still very tricky

#

especially deserializing

maiden junco
#

I will try to setup another way to add callbacks to my quests, since I don't wanna get in that tricky stuff just for running a method

knotty sun
#

I do have a solution for that but I don't think you'll like it, it's pretty tricky as well but it makes serializing things easier

# hidden flicker how do i access playerprefs from another script

I've been using PlayerPrefs for this, just started implementing in the last few weeks, Stone (to store/calculate best time and scoring and to unlock levels). Couple things that have helped in this process for me:
1). Start with simple scripts that just read you the new PlayerPrefs and whether it was recorded.
2). Have an easy/quick way to reset/clear player prefs (I have a big button on the title screen of my demo now to wipe it regularly in testing)
3). Dynamic naming conventions wherever possible. I've been using scene name as a dynamic element so that scoring is always attached to the level name.

There's a ton of support/documentation out there on how to use PlayerPrefs.

I am trying to rewrite my black hole cast script. Basically, the player casts a black hole that pulls any enemy or player to it's center. Once there, they start to take damage. I am facing an issue when trying to get the values for the Game Objects that are present. A little explanation on why. I have a script called "AssetHandlerPlayer" which holds all components and information for scripts that need to access them. Because the player and the enemy use different components and information, I created a new script called "EnemyAssetHandler" which does the same. I am trying to see if the collided objects hold any of those and do a ternary condition to give the appropriate values.

I am getting the error Use of unassigned local variable "_playerAssets" (CS0165) on the line marked with //ERROR
Here is my relevant code:
"EnemyAssetHandler" script: https://pastebin.com/Q7i9LY0v

also, important to note, the problem appears only in the "Gluttony" scripts' ternary operation for the item in the right side of the || operation. That's what stumps me the most.

Here is an example:

use | instead of || if you want both conditions to be checked. || short circuits so that if the left side is true it won't bother evaluating the right side

slate trellis

ahhh, I see. I was taught to use ||

#

thanks

somber nacelle

usually you would want to use that. in this case though if the right side is not also evaluated then your right side local variable is not assigned to, hence the error

|| and && short circuit

I see. I didn't know the difference between || and | because I haven't done any programming in anything other than Python at school. Anything I have achieved in C# was self taught and I didn't quite catch the differences. Thanks a lot!

I just started making a card game. I have a prefab for a card template. For most cases for other games, it looks like using ScriptableObjects for storing the cards makes more sense than making every card an inherited prefab of the card template. However, for my card game, some cards may be an exception depending on their artwork. For example, their artwork might slightly extend past the card border, or the card sprite might be extended to make the card feel more rare and important. But if the artwork's color scheme conflicts with the card text, the card text may have a partially transparent background so you can still read the card text. Knowing this, do you think my game should store the cards as inherited Prefabs, or ScriptableObjects?

hard viper
#

every card should have a scriptable object

#

scriptable object can hold a reference to a prefab, which you can use if needed, but I don’t think any of your cards should have a prefab on it. at most a reference to a script

lost mirage
#

Ok, I'll try going in that direction. Every card will have a scriptable object. If the card has special artwork, then it'll have a reference to a prefab

hard viper
#

for a card game, you want to minimize the number of unique prefabs you make imo

lost mirage
#

I wanted to take inspiration from some modern pokemon designs where for some important/rare cards, the artwork pops, sometimes extending past the cards borders and the section for the artwork is extended

#

maybe I could make it generic by having the card sprite actually overlay on top of the card border. If it extends past the border, then I'll have to increase the cards dimensions in photoshop and also store the position, or offset position, of the image

hard viper
#

there should just be a couple of generic prefabs, and SO should have some simple parameters

#

like an enum to specify what sort of prefab to use (eg normal card, full card art, full holo, etc), and offset parameters for the card art

because you're printing the entire dictionary

I don't know lua, but if it has classes and objects then it's probably just as confusing
Unity is designed for game development. People need to use things like coordinates all the time. So we should expect that there is something that makes it much easier than what you're doing. One of the most fundamental classes in Unity is Vector3, which can be used to model coordinates. It has an x, y, and z property. You could go further and use Vector3Int, which is like Vector3, except it uses int for its values instead of float. Creating a dictionary whenever you need properties like an object really doesn't make any sense and is bound to be confusing

# tacit swan is there such thing as audio events (same as animation events) where you can mak...

AFAIK there is no built-in event system for audio in a similar way to animation events, though the AudioSource does provide some useful functionality to build your own, such as .time which tells you how long the clip has played for in seconds: https://docs.unity3d.com/ScriptReference/AudioSource-time.html - and the .clip.length to get the max time, theres also .isPlaying if you may need any conditional checks - for example, when you play an audio, you could run a coroutine or check in Update the time passed, once it reaches a certain point call an event, wrap that logic into a class maybe with a dictionary of <float, System.Action> to represent "event (Value) at time (key)", or however youd want to set it up for your projects requirements

I moved this from code-beginner because maybe it's more appropriate here.
I'm having an issue moving a Rigidbody over time. I am trying to move it to a given position and rotation using the physics engine. I use the SmoothDamp functions, but instead of using the output, I feed the velocities through it and put them back into the Rigidbody to follow the movement. The position works fine and as expected, but the rotation is unstable. If I decrease the maximum rotation speed to something like 5, it doesn't rotate as fast, but it remains unstable and never settles. As far as I can tell the values being put in are correct. In the documentation I see SmoothDampAngle similarly being used on the Euler angles of a transform, and I have tried subtracting angles by 180 and that hasn't fixed it. Is it using the angular velocity in a different way then the rigidbody would read it, or have I done something else wrong?

image.png
quartz folio
#

Is there a reason you're not using the result of SmoothDampAngle?

leaden ice
#

You're not using any of those results

#

All 4 smoothdamp lines do nothing

quartz folio
#

The only thing it's doing is modifying angularVelocity and velocity

teal parrot
#

Yes, if I used the result directly it might try to clip through terrain and such.

#

The idea is that feeding the velocity into the rigidbody which will then move based on that velocity will be functionally the same as taking the resulting position, but it will resolve any collisions and update the velocity based on any collisions. It works with the position.

leaden ice
#

this is a really weird way to use SmoothDamp

teal parrot
#

Ping me if anyone has any amazing, very cool insight

hexed pecan
#

It should just be an extra float that you store just for the smoothdamp

teal parrot
#

I am using the rigidbody intentionally, instead of using smoothdamp directly on the rotation, I want to use it's calculation to modify the velocity only, so the rigidbody can handle collisions.

#

If it hits a wall while rotating, that will change the rotation, which should then apply in the next update.

Future note: So, cool thing, rigidbody angular velocity is one of the only angles that is handled in radians, not degrees. It needed a degree to radian conversion. Amazing.

Unable to call method from inside a namespace

So I have a namespace that is calling a method like this

Then in that ClickMovement class I have a static method with that reached target name, but I am getting a compile error saying that ClickMovement does not exist in the current context. Remember that click movement is not also a namespace, just a simple mono behavior class.

note that "namespaces" cannot "call" anything

you might have a class inside a namespace

if the ClickMovement class is NOT in a namespace, it doesn't matter where you call it from, you don't need to do anything special

Hello, I usually upload to steam and apply drm manually by uploading the executable into steam drm tool, then downloading it and replacing the original executables.
REcently, I added SteamManager from Steamworks.net plugin and it seems like when I haven't applied drm using my previous method, steam is trying to run the steam version of the game (which mean I cannot test the build that I just built because it's not on steam yet).

Does that mean I don't have to apply DRM manually anymore after I implemented Steamworks.net's SteamManager?

I need to ensure a brief tween animation finishes before I continue my script execution.

Could anyone share best practices for this? I believe this calls for coroutines and/or Dotween's 'OnComplete' callback feature, but I'm a bit confused how to implement it.

What I'm essentially trying to do is:

  1. Fade text's alpha until invisible
  2. Once text is invisible, update it
  3. Proceed to unfade the text
  4. Once text is unfaded, now do other stuff
mellow sigil
#

If the animation uses Dotween then OnComplete is the natural way to do it

rocky basalt
#

Cool, that's what I figured. It's kinda ugly code, though to have the very important OnComplete buried at the end of a list of tweens

#

Was hoping to figure out a more readable way

Guess I could use a dotween Sequence, tho

I want this progress bar code to work for like 2 minutes or any time I enter

fervent furnace
#

you want the bar completes for any time period?

#

eg if you want it load for 60 second, that means the bar should propagate 1/60 fraction (of itself) pre second, so how you manipulate the speed?

when i turn off simulation in rigidbody it works

i fixed, no i didnt

soft shard

#

yeah

#

its always grounded

#

somehow...

#

but when i turn off simulation it detects ground normally

soft shard
waxen matrix
#

lemme check

#

wait

#

when i used it != instead of == its now not grounded

#

it looks like it hit something

soft shard
# waxen matrix when i used it != instead of == its now not grounded

The code you posted was using !=, which from what you described, was making it always grounded, so flipping the operation to == would make sense to do the reverse where instead it would always be false, since your check would then be saying "if the thing hit IS null then consider grounded true", using != would be saying "if the thing hit is NOT null (meaning its something) then consider grounded true"

waxen matrix
#

well..

#

it looks like it hit himself or smth, cuz when i turn off rigidbody it works

#

i mean simulation*

soft shard
#

Well if you log the collider your raycast hits, does it return the name of itself?

waxen matrix
#

lemme try

#

it hits himself

soft shard
# waxen matrix it hits himself

Ah ok, so likely because your raycast may be starting from inside your collider, it will be the first thing to get hit before your ground, the version of Raycast your using is only taking into account the position and the direction along with a distance, so you could either try moving the position outside of your collider (though there may be cases where it is not precise enough), or you could try putting your player on a different layer than your ground and also include the "layermask" param: https://docs.unity3d.com/ScriptReference/Physics2D.Raycast.html - I usually make a public LayerMask listenForThese, anything thats checked on those layers are the only colliders that are ever detected by the ray, and will pass colliders on different layers than provided to that variable (you can also do this manually with bitmasks, but I find those more complicated to understand)

waxen matrix
#

well...in 3D games i didnt used it, i just dont want to change every object in scene

soft shard
#

You shouldnt have to change every object, you would only need to change your player - for example, if your level is using "Default" as their layer, but your player is also using "Default" you could make a new layer called "Player" and just set only your player to that layer - your raycast layermask can then just only look at your "Default" layer and ignore your "Player" layer, which would then detect your level, and not your player

waxen matrix
#

ohhh

#

thank you so much

#

i ddint know that i can make it work like this

soft shard
#

Np, you can do a lot of cool and useful things with raycasts and layers for sure

Guys any idea as of why the pivot of the avatar gameobject moves in the scene while its position is not altered at all?
I mean I want it to be stationary and its children to move around but It seems that while it is stationary in the inspector, it is moving in the scene.

Tge pivot isnt changing, the center is changing, in the corner of your scene view yiu can see a thing that says center, change that to pivot to see the pivot

Delegates, Events, Actions and Funcs - The Observer Pattern (Unity ...

The observer pattern is essentially baked into C# and Unity. It comes in the form of delegates, events, actions, and to some extent funcs. The observer pattern de-couples the source of information from the object receiving the information. This makes unity projects more stable, easier to add mechanics, and far less likely to break.

i have a take damage function in the player script whic is refering in a code that damages the player in the enemy script. I put a print in the takedamage function in player script and it works but the player dosen t take damage.

I've currently got a system whereby two objects will be dragged around the scene by the player. When one object touches another it should create a new 'GroupObject' empty which both objects should set as their parents. However, when testing it out it seems the parenting isn't quite working right. I am aiming for the ObjectGroup to be the parent of both.

I am assuming this is because they are both fired at the same time, but is there a way to stagger them or ensure they both get parented correctly?

       ObjectSnap otherSnapScript = collision.gameObject.GetComponent<ObjectSnap>();

       {
           GameObject otherObj = collision.gameObject;

           if (otherObj.transform.parent == null)
           {
               var groupObject = Instantiate(EmptyParentPrefab, collision.transform);
               Vector3 snapPosition = CalculateSnapPosition(collision.contacts[0].point, collision.transform);                    
               transform.position = snapPosition;
               otherObj.transform.SetParent(groupObject.transform);

can unity recompile at runtime?
Ie: if I have some unity code that writes unity code, and I want it to be written anew each time the game runs, can the code be written on startup and then used after it is written?

leaden ice
static matrix
#

unfortunate

leaden ice
#

You could do something like that if you include a scripting engine for your game

#

e.g. moonsharp

#

what are you trying to accomplish with this though

#

modding?

static matrix
#

I essentially wanted to make a script that would write a script that has a unique effect, from a list of effects
without using a massive switch-case

hard viper
#

the main use case I’d imagine would be doing a redstone-like thing in minecraft, and then compiling it into machine code

static matrix
#

I could flick a ton of bools on and off but that's kinda annoying

leaden ice
leaden ice
static matrix
#

yes, I probably should

leaden ice
#

or a dictionary

static matrix
#

delegates my beloved

leaden ice
#

or even a dictionary of delegates

static matrix
#

or a delegate that returns a dictionary of delegates? \j
or have I gone too deep

hard viper
#

it sounds like the thing in God Eater 3, where the player can make custom particle effects

#

for their guns

#

but i think you can accomplish this without compiling it during runtime

#

is this accurate?

static matrix
#

i'll use delegates

hard viper
#

I would personally make a POCO which represents a given particle effect. which might include a list of another POCO. Inner POCO represents an individual components of a particle effect with different parameters etc. The big POCO containing it manages timing, access, and stringing them together.

static matrix
#

delegates will at least cut down the switch cases massively, limiting more to conditionals
even then, maybe I wont need any

#

this is a good idea

hard viper
#

delegates are good as long as the parameters do not change

#

individual classes are better if individual parts need to hold different parameters.

static matrix
#

by "parameters do not change" do you mean the types do not change or the values do not change

hard viper
#

the arguments and output type do not change

static matrix
#

ah

#

should be easy enough

hard viper
#

abstract class is better if the inner components can be really different.

heady iris
#

that's where you'd use polymorphism, yeah

#

so I guess there's a hierarchy here

#

if you always do the same thing, you just hard code it

#

if you do different things of the same kind, you need to add delegates

#

and if you do different things of different kinds, you also need polymorphism (or something else that allows for different types to be used)

#

System.Action<object> yolo

#

Things can get frustratingly abstract when you allow for too much customization

#

I'm rewriting a game right now to make it a lot more..."general", and it has made a lot of things more annoying

#

i can no longer have a global setting for "enemy difficulty" because there's no longer a single enemy class and a single player class

hard viper
#

i have a little circuit thing in my game with logic gates, and pressure plates etc. That I handle with an abstract class that gets very derrived. This way I can also check if the class implements different types of interfaces

#

for other things, I might keep a Func where I use a single switch case to assign a given function to a delegate, to just hold a given type of behavior

#

eg a sensor that can detect player, or enemy, or solid. Assign a Func<GameObject, bool> based on an enum, where the Func says true/false is this gameobject relevant to the sensor

#

instead of making 1 class for each

heady iris
#

yeah

#

There's a sliding scale of where you put all of your logic

#

one extreme is just writing code for everything

#

the other is doing everything in the inspector

#

the latter means you can construct arbitrary behaviors at runtime

#

but it also means that..none of your logic is actually compiled C#

hard viper
#

i try to keep inspector primarily for just adding components, setting collider/rb/sprite settings, and clicking serialized enums/bools to turn on/off different class behaviours in C#

#

keeping consts in C# in general saves me more than it hurts me

proper bolt
#

Seeing something a bit odd, I can see my regular inventory in the inspector but the structures one is blank. Not sure why :/

image.png image.png image.png
leaden ice
#

not that this is also just the script defaults. The inspector for an actual instance of this script will be a bit different

#

only UnityEngine.Object fields will show in the script defaults inspector

proper bolt
#

I've not manually made the structure slot not one of those, so what is it that determines whether one is a .Object or not?

leaden ice
#

e.g.

public class MyClass : MonoBehaviour``` this derives from UnityEngine.Object
```cs
public class MyClass``` this does not
#

MonoBehaviour is a subclass of UnityEngine.Object

#

same goes for ScriptableObject

proper bolt
#

None of them extend Monobehaviour

image.png image.png
#

Although I have just spotted that this has a serialisable tag, could that allow it to display in the inspector even though it doesn't extend that?

image.png
leaden ice
hard viper
#

the whole thing needs to be serializable to work

#

and then structure needs to be serializable too…

proper bolt
#

So i'd need some way to define how the inspector should serialise my custom structure?

#

how to i stop it looknig smooth I use TERRAIN

Screenshot_2024-01-03_170032.png

#

if A contains B contains C contains D, then B C and D must all be serializable for A to be Serializable

proper bolt
#

gotcha

hard viper
#

also, some data structures can’t be serialized by default. fair warning

#

eg Dictionaries

proper bolt
#

with this I managed to see the list in the inspector, but of course the actual structure is just blank

image.png image.png
hard viper

looks like Structure isn’t serializable

proper bolt
#

yeah. not sure how to make it so though

#

haven't delved into that yet

hard viper
#

go to structure. make it serializable lol

proper bolt
#

is it literally just that tag that you need?

#

yeah

#

it needs that attribute

proper bolt

I assume it would require some other fancy code to get working

doesn't like the contents though it seems

not if everything in it is easily serialized

            Debug.Log(name);
            this.actions[0]();
        }
    }
}

for some reason, with this code
after the instantiation:

if(Input.GetMouseButtonDown(0)){
            var Proj = Instantiate(Projectile, transform.position + transform.forward, transform.rotation);
            Proj.GetComponent<Projectile>().IsPlaceholder = false;
        }

the debug.log logs the name of the new object, but for some reason the placeholder runs actions[0](), and moves forward. The copy has its body set to its own, not the placeholder, so im not totally sure what is going on here.

proper bolt
#

I assume then that the gameobject can't just be serialised like that then?

static matrix
#

just reassign it, its because there was something in it but then you changed the type of the something or of the collection, and now they are mismatched

hard viper
#

but that class also needs to serializable tag on it

#

also, if it’s serialized, i expect the only gameobejcts in it to be prefabs

#

and not gameobjects that are instantiated during runtime

#

because otherwise you’d only serialize a reference to something that doesn’t exist

proper bolt
#

It'll be prefabs that are instantiated, combined together into one structure, then saved to spawn somewhere else later

static matrix
#

is it something to do with the statics? I dont see why the placeholder would be running the function through the copy

proper bolt
#

so at the moment I guess it's storing the gameobjects in the scene itself, how could I instead store just the prefab?

hard viper
#

drag prefab from assets to the field in inspector

#

do not drag anything from the scene

#

because that connects to references to gameobjects in the scene

fervent furnace
#

google serializable dictionary unity

#

unity inspector doesnt support serialization of usual dictionary

static matrix
#

am I setting references wrong? im not sure why it is doing this

proper bolt
#

Think I figured something out. Added a prefab holder script that I can get the prefab from. probably isn't the best way but honestly at this stage I really don't know what's right or wrong

#

although it still says missing

image.png
#

so I guess that didn't actually work lol

hard viper
#

but then the program needs to get a reference to the prefab from somewhere

#

and if you want to serialize but not show in inspector, you could always use the HideInInspector attribute

proper bolt
#

I thought maybe I could slap something like this on the object then do this to store the prefab itself

image.png image.png
#

though I don't know if that's working at all

hard viper
#

it’s unfortunate that prefab and gameobject aren’t different classes sometimes

thick socket

    {
        textMesh = GetComponent<TextMeshPro>();
        baseColor = textMesh.color;

    }

if I disable/re-enable this object often will this just be called once?

fervent furnace
#

yes

thick socket
#

or each time this is "enabled" it will call this again

hard viper
#

Awake is only called once

thick socket
#

darn thanks

hard viper
#

OnEnable and OnDisable are called whenever you change

thick socket
#

running into a weird bug that I can't seem to fix

proper bolt
#

since it still says (1), which means it's just the object from the scene "ProcessedItemPrefab (1) (UnityEngine.GameObject)"

hard viper
#

hey tina, you might be the best person to ask. Do you know a fast way to count the number of leading zeros in a uint?

thick socket
#

this showText is being ran once every second

#

the text grows bigger and then smaller and disappears as it should the first 2 times

hard viper
#

a lot of ways use recursion or if statements, but i’m not sure if there is a smarter way

thick socket
#

then after that it only seems to "appear" on the 2nd half where it goes smaller

hard viper
#

since it is just bitmath

thick socket
#

but not while its growing bigger(dispite the object being enabled it isn't in view for awhile)

#

hoping Im overlooking something small but not sure what Im doing wrong

hard viper
#

i can make a uint just the rightmost turned on bit already. I would just like to know the index of that bit

#

eg Log2

fervent furnace
#

i am not good at bit manipulation....i cant even understand population count....

hard viper
#

really? oh mb

#

i don’t understand the popcount function; but i do know it is slick af

#

i copied from microsoft’s BitOperations source code, and it works really nicely

fervent furnace
#

btw i think the one use recursive based on divide and conquer.
if i>>16!=0 then the one must occur in range [17,32) else [0,16]

hard viper
#

i saw the recursive one, which is nice. i wasn’t sure how good recursion is in terms of stack frames when bit math gets involved, since bit math is stupidly cheap

severe creek
#

how can i make options in a random function rarer or more frequent?

hard viper
#

maybe i’ll just make a stupid semi-hard coded version

hard viper
#

or use a cdf

fervent furnace
#

oh, my way is binary search, population count is divide and conquer (add the right part and left part recursively, and idk why how the bit shift version comes up)

hard viper

hard viper
#

do you know how to make a uniformly random number between 0 and 1

#

actually, are you trying to pick a weighted entry from a list, or make a random number that follows a different distributikn

#

the two are very different

#

for a random number: define an inverse cdf for the random distribution. then call the inverse cdf on a uniform random float between 0 and 1.

#

this would let you turn a uniform distibution into a normal distribution, for example

severe creek
#

i want to instanciate different things with diffrent frequencies, those are in an array

hard viper
#

but if you have like a rouguelike card game, where cards need to be weighted, then that’s different

severe creek

i want to create a sort of dungeon with diffenrent rooms. some of those should occur more often then others

This is in my late update:

    public void LateUpdate()
    {
        if (holdingFirearm)
        {

            Vector3 difference = targetTransform.position - rightShoulder.position;

            

            difference.Normalize();
            
            rightShoulder.up = difference;

......

The right shoulder is to the character's Shoulder.R armature bone. My Character's right shoulder points towards the mouse, but the character's arm is bent by the elbow, so that the right hand ends up pointing to the side, instead of towards the mouse. How do I make the entire right arm point straight towards the mouse.

image.png image.png
hard viper
#

ok, then give everything a weight, count the total weight, generate a uniformly distributed random number that goes up to total weight. Then iterate through list going:

cumulativeWeight = 0;
foreach entry in list
cumulativeWeight += entry.weight;
if (cumulativeWeight > randomNumber)
return entry.

severe creek
#

ok thanks

hard viper
#

does it make sense why that works?

severe creek
#

yes

hard viper
#

good luck

#

you can optimize that later, if you call this function a lot, and the list has lots of entries

#

for now, this should be the basics

Good day! I have this idea where the user can set the number of points they want to achieve for ex. 10 points, then if they reach it, the game would be "Finished", they can also save their points if they can't finish.

The problem is, I can't find any tutorials where the user will win if they reach a certain number of points. (This is basically the problem)

Do you guys have any idea or video links on how I can implement this? I'm using firebase as my backend btw

fervent furnace
#

how you save the data is nothing related to your problem....? or you want to perform the check in backend

not ""

#

how do i access the second part of each entry in a dictionary to put it into an array?

leaden ice
# 
myDictionary.Values.ToArray()```
severe creek
#

how do i use this in code

leaden ice
#

wdym

#

this gives you exactly the array you want

#

do whatever you want with it

#

You probably want to start by storing it in a variable

#

A question though is why do you feel you need it in an array specifically? What are you ultimately trying to do?

severe creek
leaden ice
#

e.g.

float total = myDictionary.Values.Sum();
float randomValue = Random.Range(0f, total);
GameObject result = null;

foreach (var pair in myDictionary) {
  randomValue -= pair.Value;
  if (randomValue <= 0) {
    result = pair.Key;
  }
}```

Yes, you're missing using System.Linq;

#

Your IDE should automatically suggest that for you.

hard viper
#

i would avoid iterating over a dictionary for this

#

unless you can represent weight with simple integers

leaden ice
#

I mean I probably wouldn't use a Dictionary in the first place, it's not really necessary. Just a List<ItemWeightPair> or something would be just as good. But I don't see an alternative to iterating over whatever the collection is

severe creek
hard viper
#

and are all the ints very small?

severe creek
#

no

hard viper
#

like <10

#

ok then dictionary isn’t a smart idea imo

#

how big are the ints

severe creek
#

20-50

leaden ice
#

I'm not sure I see how the size of the ints matters

hard viper
#

if it isnt too big, you could just add the weight as # of copies into a giant list, pick a random number between 0 and count-1, and go straight to the index

leaden ice
#

Ah - sure - I mean the optimal way to do this is set up an interval tree

#

but that's a lot of work 🤣

hard viper
#

or dictionary, where you get your calculated random value (between 1 and total weight), then iteratively check for keys at randnumber, randnumber +1, randnumber +2… and if the weights are all small, you’ll iterate only a few times

leaden ice
#

If there's less than 100 items in the loot pool, the cost of iterating will be negligible anyway

hard viper
#

idk, at first, just make a list and iterate manually

#

don’t get fancy and optimize prematurely until you see it’s actually super expensive

#

then optimize

i have a general question on Collision2D being enabled/disabled. I have a platform effector which is one way, and can make collisions not enabled. However, i have 2 different collisions with the same one way collider, which both have the same normal, and have very slightly different Collider2D.Distance (-0.011 vs -0.005), and the -0.011 is the one that is enabled

#

question: what is the rule for a platform effector2D disabling a collision2D?

hi guys, this is the attack animation like dash and bum. child object have animation and parent have collider how can i fix it :/ I don't know if I explained it fully.
animation plays but parent not following and when animationd ends its turn back i dont want it 😦

image.png image.png image.png
normal quest
hushed wedge
#

yes 30 frame

knotty sun
normal quest
#

the reason it goes back is because it is locally animated. Parent objects transforms its children with it, while child objects don't transform the parent with them. Also if this is the sprite sheet the child isnt really moving, just playing the animation

#

in order to fix that you should have a sprite sheet where the animation doesnt move, so you can move the gameobject

#

if you don't have that sprite sheet, you could try moving the parent to the position where the animation ends (lets say 4 units (for example) to the left or to the right depending on where the player is facing)

#

animation ends -> move parent immediately

hushed wedge
#

i will try thank you

normal quest
#

that should fix it in a dirty way, if you want to do it cleanly you should have a static sprite sheet (where the character doesn't move, just animates) and move the game object according to your animation

hushed wedge
#

yes I am trying that:

#

Anyone have ideas - When scripting something with many sequential steps - namely a tutorial - what are convenient ways to organize the sequence so you can easily edit it later?

Right now each of my steps has an integer ID. But I'm concerned as it grows into dozens of steps, I'm gonna waste a lot of time editing the integers for all the steps as I insert/remove them

leaden ice
#

Or assets like NodeCanvas

rocky basalt
#

Oh interesting. I had thought Timeline was mainly just for animations

#

My tutorial has a lot of animations, but also just gameplay behavior changes, where a user is prompted to test out features of the game

i’d like to run by my sketch for a collectible system, if anyone has time for feedback:

public class CollectibleCollector : Monobehaviour {
[SerializeField] private CollectibleType collectibleTypes;
private void OnTriggerEnter2D(Collider2D col) {
…check if it is a valid collectible and call ICollectible Collected()
}

public class CoinBehaviour : Monobehaviour, ICollectable {…}

public class CollectionManager : Singleton<CollectionManager> {
private Dictionary<CollectionType, int> collectionCount;
….methods to manage
}```

hey, I want to generate rooms next to each other and i have a script to do so. Now i want to implement so that some rooms can only spawn next to a specific room. does anyone know how?

somber nacelle
#

that's fairly vague and will likely also be dependent on how you are generating and identifying rooms

hard viper
#

each room would need to be represented with a class with a function that can return a bool about whether or not it is valid

raven orbit
hard viper
#

then I would iterate through your list, only add weight from vaild entries, get the total weight, get random total weight, then iterate again

#

or make a list and save the result in between or whatever

#

but at the core, each room needs a function that can telll you if it is valid

somber nacelle
#

wave function collapse algorithm would be useful for that too, though it may end up requiring a rewrite

hard viper
#

this might be pretty simple tbh.

#

for making a dungeon, you’d probably only want on the order of like 30 rooms at a time or something, usually. so you can just eat the cost of doing this the dumb way once

severe creek
#

so i should use a wave function collapse algorithm?

hard viper
#

focus on the basics first

#

you need a function that tells you if a room is valid

#

and to define that function well

#

then the filtering and randomness etc will be the easy part

somber nacelle
#

that's how the wave function collapse algorithm works btw. you define valid neighbors then it starts with the object with the fewest possibilities, then iterates the valid neighbors on its neighbors, then repeats until generation is complete

#

basically think of a sudoku solver. it determines all of the possible values for each empty square, then starts with the square with the fewest possible values, selects a value, the updates the others with what is still possible, then selects the next square with the fewest possible values and keeps repeating that process until the puzzle is solved

hard viper
#

in all cases, you need to define what constitutes a valid room. that is the hard part, as there can be a lot of logic in there depending on how fancy you want to make it

#

it could be based on how many of a given type of room is allowed to appear, or how many connecting entrances etc there are

#

that’s not something we can help with, but we can help with what comes after

somber nacelle
#

yeah initially defining what is valid will be the difficult part. unless you only care about what room types are next to each other, then you just need a way to identify the rooms types (like an enum). in that case a simple switch statement would be enough

severe creek
#

thanks a lot

hard viper
#

wave function collapse algorithm assembles puzzle pieces

#

the hard part is defining the rules for the puzzle pieces

#

if that makes sense

severe creek
#

is it possible that a room is only valid if a neighbouring room is next to a specific room

somber nacelle
#

you just need to be able to express those rules in code. for example, you would check that any of its neighbors are that specific kind of room and if not then it is not a valid option

severe creek
#

yes but how can i check the neighbours of a neighbouring room

somber nacelle
#

that entirely depends on how your current room generation works. typically you would keep them in some sort of collection

severe creek

After creating a building, an animal or a character, etc. in my game, I would like to add it to a specific runtime collection. I have a collection for each entity type (BuildingCollection, AnimalCollection,etc.)
Now, I want to know where I should call method Add when spawning or Remove when destroying that entity.
In Spawner class or in that Entity Class for example Building in Start/Awake? where?

Where do you prefer to put it?

leaden ice
#

The most convenient place is probably the spawner script

#

The entities could also register themselves with whatever collection manager is relevant in their Awake() methods

hoary mason
heady iris
#

so this is basically force-based AI

#

you have a force pushing towards the player, and forces pushing away from obstacles

hoary mason
#

well, towards the tree in this case

#

but yeah, since I'm using the steering to control velocity

#

I think what's happening is that it's detecting the other enemies, then moving away, but then stopping detecting said enemies and going back to the tree, but then detecting the other enemies again

#

and so on

lunar acorn
#

how do you do two finger touch in unity new input

earnest gazelle
#

By the way, In Spawner, it is OK as well

#

For each type (Character, Animal, Strcture (Buildings, Plants, etc.)), one spawner/factory exists but I think it could have been one spawner for all of them if I kept all definitions in one array and not different collections for each.
I think the number can increase by adding new entity types. As an instance, if I add natural features, I need additional classes for it, NaturalFeatureCollection,NaturalFeatureSpawner, NaturalFeatureLoader and so on

Yep. I do that pretty often.

I have a gameObject that has been made into a prefab (it has AI scripts attached - all enemies will share generic AI) and subsequently removed from the scene. I create instances of this prefab as my enemies, in code. I want this object to have a script attached to it that stores the various data for the enemy (name, health, damage etc) so they are easily accessible and generated at runtime - I don't want to create hundreds of different prefabs for each possible enemy type and enemy level. The only way I can seem to achieve this is by making the class a MonoBehaviour, which seems unnecessary since it's just a POCO and contains no methods, only properties. Is there a better way to achieve this? ie add a normal class to a prefab or is there no detriment to making the data class inherit from MonoBehaviour?

heady iris
#

sounds like you want to store the data separately from the prefab

#

if you don't want to create hundreds of prefabs

ionic bobcat
#

I want to create the data at runtime when I create an instance of the prefab

heady iris
#

I presume you have a class that will actually hold the health/name/damage/etc.

ionic bobcat
heady iris
#

you'll want to instantiate the prefab, then pass that data to the component (or components) that need it

# 
var enemy = Instantiate(wolfPrefab);
enemy.Configure(scaryWolfStats);
#

where scaryWolfStats is a...

# 
[System.Serializable]
public struct EntityStats {
  public string name;
  public float health;
  public float damage;
}
#

Now, if different kinds of enemies have different kinds of stats, things get more complicated.

ionic bobcat
#

Yes, that's basically what I've come up with. It just seemed a bit off to me.

#

Thanks for clearing it up 🙂

Anyone know an alternate method for 2d pixel perfect? I tried using the Pixel Perfect Camera extensions, and it does what it's supposed to do, but it makes certain moving objects very jittery, and that stops happening as soon as I disable the component. I'm trying to recreate the genesis sonic games style in terms of how the game should be rendered. Apart from the 4:3 screen ratio.

#

Are you using a cinemachine camera aswell?

cunning radish
#

No I left it and made custom camera movement

Changing the jittery objects' rigidbody interpolation mode doesnt seem to have an impact

karmic brook
#

Your reference resolution seems a Bit specific are you Sure its correct?

cunning radish
#

It's correct in the theory, since I'm trying to mimic another more modern 2D Sonic game's resolution.

#

although I just tested 384x216, and the jitter is well, still there, i think its a low resolution thing

#

making the resolution bigger does look like it makes the jitter go away, but then I'm stuck with a large camera

karmic brook
#

By large camera you mean Low FOV?

cunning radish
#

just the camera size property under projection

#

I messed around with reference resolution some more, and I found a camera size, that although isn't perfect, it doesn't have the jitter, and it's a not too bad, so I think I'll just take it.

iron pumice
#

normal quest
#

what does that common function do?

latent latch
#

they should still be different instances

normal quest
#

and that function detects the first available red square?

latent latch
#

if you're using mouse controls or touch you should consider IPointerHandler interfaces

#

you need a way to detect which slot was the one selected so you'll have a GO for each

#

that's the most basic implementation

#

depends how you've got it all set up, but where are the spells on the left located before the right

#

another UI element I'd assume

#

Ok, so the right is like a hotbar and the left is what the player has

#

So two manager type scripts, they don't need to know the exact type of spells, but they need to know the types they store

#

you do need a slot script though for each GO

#

and like I was saying you'd need IPointerHandler if you are using mouse

#

OnClick should be fine too

#

if you wanted dragging though probably IHandler

#

Well, each GO should have its own script

#

so all you're doing is taking that stored instance and passing it over to Manager#2

#

OnClick should be fine. If every slot has its own OnClick and it's targeting the script on its own GO then it will reference that exact instance

#

right, you need to attach it to their own GO

#

I'm not sure how you can even link parameters like that with OnClick

#

IHandler you can though

#

regardless, I don't recommend that way. It's better just to localize the scripts on each GO itself

latent latch
# latent latch I'm not sure how you can even link parameters like that with OnClick

Ah, ok just playing around with it I can see two ways to do it like this if you wanted, but it's by referencing by the GO, other by creating individual methods for each slot.

For #1 you'd have to map out the reference probably through a dict such that GameObject 1 references Spell Slot 1.
For #2 you'd have as many extra method calls per GO on the UI

#

or my method:
Each script doesn't care for what slot it is, but it knows that if you click on it, the stores spell reference will be added to Manager#2

You know... A lot of C# shortcuts I understand intuitively; but I've never understood exactly what bool = !bool translates to (I don't mean what it does. I know what thew result is.)

For instance int = bool ? 1 : 0 means if the bool is true the int will be 1, and if it's false it will be 0. What does bool = !bool mean in words?

       rb.velocity = new Vector2((moveVector.x * moveSpeed * Time.deltaTime),(moveVector.y * moveSpeed * Time.deltaTime)); //Movespeed around 3000f to move same speed using Rigidbody2D

#

cc.Move moves you exactly with the parameter value you put in

a velocity is movement over time. Like movement over 1 second

so if I have a 30hz physics rate, and a velocity of 10,000 then my movement per tick is going to be like 10000 / 30

#

Like are you expecting triggers to trigger as soon as this code runs?

#

Or later on?

calm talon
#

I'm expecting trigger events to occur after it runs

#

well right after it runs since the new area the collider will cover will intersect other gameobjects with colliders

somber nacelle
#

if you want trigger events to occur in reaction to the changed collider then you will likely need to disable and reenable the collider

the problem is that no trigger event occurs at all
