[spark flower]

well the array is for starters a length of 0, and i just wrote that assets[^1] = _item; and it gave me the error. i assumed that this wuld extend the array and assign the last index to _item

[quartz folio]

you assumed, and you were wrong

[dusk apex]

Oh no, it only substitutes the length minus one necessity.

[spark flower]

yes, nice deduction

so it doesnt resize the arrya?

[dusk apex]

You'd still need to resize the collection

[spark flower]

its just the last index

i get it

so array[^3] is basicyl array.length - 3?

i alredy saw the 💯 so i alredy know, i wont try it

[lean sail]

You could possibly just use overlap box to see if anything is in the area, but im unsure what method you are originally planning to check with since you said something about the hit point - collider.extents.

Oh I zoomed into the image

Yea that's really about what I'd do

[winged mortar]

Boxcast?

[edgy pumice]

@winged mortar first time I'm hearing of it o_O

[lean sail]

I assume not a boxcast since itd essentially check if the object could be spawned along the entire distance rather than at the furthest point of the raycast

[winged mortar]

Wouldn't it collide near the end?

But yeah that is a good shout

[lean sail]

If you are standing beside something it's possible to hit that object, even if you're looking into an open area

[winged mortar]

If you are trying to place it next to a corner, you'd have line of sight yourself but the boxcast might get stuck on the corner

Depends on if this is relevant for his game

[edgy pumice]

That's why I was first thinking of a raycast to evaluate an approximate distance to an obstacle and work with further checks from that point on

and that's why I was also going to decrement half of the height of collider box from the raycasthit2d.point to not clip into a wall

and then start checking for overlaps

[winged mortar]

Works fine but you can't guarantee your position to be perfect

Honestly I'd try boxcast, see if it works with your current setup

And then try to do it yourself

[lean sail]

I think you'll have to use more than the height, so it shifts over towards the player in the reverse raycast direction by the entire extents of the object

Basically height and width

[edgy pumice]

I was hoping to take as small increments as possible in reverse direction, but that is rather, a secondary concern

Okay, I'll read up on boxcast and think of how to handle it

it's basically just lots of geometry. I was just hoping there's some bigbrain way to handle it XD

@winged mortar From what I'm reading about boxcast - it may actually make my life easier

Thanks, guys

[winged mortar]

It won't work super well with larger objects

So it really depends

I'm generating a mesh for a subdivided quad and tried adding backface triangles (see: second for loop), but for some reason my normals(?) are going all out of whack. Any clue what could be causing this? It works fine with only the front facing traingles

[quartz folio]

These are the normals without backfaces vs the normals with.
I imagine the issue is that it doesn't know which face to use to generate the normals associated with a vertex, and you will need to specify the normals yourself

[elder zenith]

Oh lord alright

[quartz folio]

+ mesh.normals = Enumerable.Repeat(Vector3.up, vertices.Length).ToArray();
- mesh.RecalculateNormals();

and it looks good

[elder zenith]

this would also make the downwards facing tris have their normals face up, right?

[quartz folio]

Yes

[elder zenith]

not that the visuals matter, just clarifying

[charred rock]

Hello! What is the recommended way to run a static method before the editor stops play mode. The static method is inside a static class, and ideally I would like to avoid having to have a monobehaviour in my scene, since it is for editor only purposes.

[elder zenith]

first time seeing Enumerable.Repeat(), that's interesting

[quartz folio]

Subscribe to playModeStateChanged from something like [InitializeOnLoadMethod]

[charred rock]

Thanks for the answer and the references :)

[quartz folio]

It's not the most performant, but it's certainly a lazy way to get it done 😄

[elder zenith]

Ah, when I change the mesh vertices I also recalculate normals

So it looks fine when freshly generated, but gets screwed the second I start trying to change it

[quartz folio]

The vertex normals shouldn't be straight up when you've distorted the mesh, so annoyingly you'll have to calculate them

[elder zenith]

That sucks, I can't implement that, would take too much processing

I have another way I can do the thing I was trying to do

[quartz folio]

Why? It'd take the same amount of processing it was previously doing with RecalculateNormals

[elder zenith]

So it's fine, I was just hoping to get away with raycasts

[elder zenith]

oh would it?

[quartz folio]

I mean, RecalculateNormals is calculating the normals, so yeah, if you do it yourself it's gonna be the same kind of impact 😄

[elder zenith]

do you by any chance have a useful resource for this?
im guessing i only need to calculate the normals for the first half of the tris and set the other half to Vector3.up or something

nevermind, got GPT to do my work for me

should uh probably do some research on it later

[quartz folio]

what did it come up with, I am interested to know if it failed

[elder zenith]

works just fine

https://hatebin.com/sryoyuqwzu

here's its response

[quartz folio]

That's pretty similar to what I did:

// Normals
normals = new Vector3[vertices.Length];
for (int i = 0; i < triangleLength; i += 3)
{
    int i0 = triangles[i];
    int i1 = triangles[i + 1];
    int i2 = triangles[i + 2];
    Vector3 a = vertices[i0];
    Vector3 b = vertices[i1];
    Vector3 c = vertices[i2];
    Vector3 n = Vector3.Cross(b - a, c - a);
    normals[i0] += n;
    normals[i1] += n;
    normals[i2] += n;
}

for (var i = 0; i < normals.Length; i++)
    normals[i] = normals[i].normalized;

[delicate flicker]

What are othey ways for accessing variables from another script? Referencing through "GameObject.Find()" and then "GetComponent<>()" is tedious and becomes quickly messy in the code. Inheritance of multiple classes is prohibited. Static variables as i figured out recently are quite dangerous to use. So what are the other ways?

[elder zenith]

i told it to only worry about the first part of the triangles array, since i dont care about the other half, hence the /2 on the length

[quartz folio]

Initialising the array to 0 is redundant, C# does that already

[elder zenith]

oh the default value for a created Vector3 is 0,0,0?

[quartz folio]

Yes, floats default to 0

and structs cannot be null

[elder zenith]

hm interesting

[quartz folio]

And normalizing in the inner loop will not really produce much value. Inigo Quillez's article on the topic goes over it

[hexed gulch]

    {
        Quaternion rotation = Quaternion.LookRotation(-hit.normal , hand.up);

        target.SetPositionAndRotation(Vector3.Lerp(target.position, hit.point, _armMoveSpeed * Time.deltaTime),
            Quaternion.Lerp(target.rotation, rotation, _armRotationSpeed * Time.deltaTime));```

i have a script that im trying to make a IK procedural hand placement so if the player moves towards a wall the hand will attatch to it, and currently it works good but theres one problem i cant figure out that involves this line:

```Quaternion rotation = Quaternion.LookRotation(-hit.normal , hand.up);```

when the hand moves to the wall it never rotates flat with the normals it always is at an angle with the raycast but i want it to be flat against the wall as seen in this picture i would love a smart person to help me out

the raycast u can see is from the hand to the hit.point

[elder zenith]

The way I'd do it is find a vector opposite to the Trigger from the player's perspective, then apply it using Rigidbody.AddForce().
Simplest and roughest way you could do it is just subtract the player's position from the trigger's position.

Vector3 pushOutDirection = (other.transform.position - transform.position).normalized;

other.GetComponent<Rigidbody>().AddForce(pushOutDirection * pushOutForce);

Have the pushOutForce be a variable that you can adjust

[prime sinew]

No

They are separate, and should not be used together

It's one or the other

If you want physics, you use rigidbody

[elder zenith]

Oh, my bad, I missed that part

[prime sinew]

This issue would be simpler with rigidbody imo, but only because I don't use charactercontroller

[elder zenith]

You can use CharacterController.SimpleMove() perhaps?

[bleak python]

That depends on what you're trying to do. Do you have an example use case?

Often you can assign the desired component in the editor

[weak dove]

Hi, I'm having a problem with inherited class variables, it's probably a simple problem but I'm not experienced with interfaces and properties.

I have an interface IInteractable with this property:
bool Hold { get; set; }

The class InteractableObject inherits from this interface, and has this code:
public virtual bool Hold { get; set; }

The class Chest inherits from InteractableObject and has this code:
public override bool Hold { get; set; } = true;

The idea being that any objects with the Chest class should have their Hold variable set to true. This works as expected, but I get this error:

The same field name is serialized multiple times in the class or its parent class. This is not supported: Base(Chest) <Hold>k__BackingField

Even though the game works, the error shows up whenever I save my code. Can anyone show me how to fix it?

[quasi pagoda]

@knotty sun I was able to resolve my issue with the code. Thanks for your help.

[sage latch]

You shouldn't be getting that warning, but removing the backing field should resolve it. I assume you don't need to set the Hold property, so just change it to this:
bool Hold { get; }
public virtual bool Hold => false
public override bool Hold => true

If you didn't know this, saying bool Hold { get; set; } in a class is actually just a shorthand for:

bool _hold; // backing field

public bool Hold {
  get => _hold;
  set => _hold = value;
}
```Unity doesn't usually serialize backing fields, which is why that warning is odd.

#archived-networking

[wintry crescent]

pretty sure you have to make the bool hold in the interface virtual as well
and override in both classes

that's how I solved it last time I did something like that, if I remember correctly

[delicate flicker]

Some score variable for example. You need to access it in a couple of UI scripts, some other scripts attached to gameobjects etc. Everytime you have to Gameobject.Find().GetComponent. Or use it as a static variable and then a problem of not resetting static variables arrives when you reload the scene.

[thin aurora]

Lol no

Virtual is completely optional and only relates to the implementing class

Virtual means "I can be overridden if you want to" and what you're talking about is most likely abstract. You don't have to override it unless it's abstract

[bleak python]

You could attach the script to a score manager game object or something, and pass this object to those who need it in the editor

If that suits your scene

[tired elk]

Doing it like this removed the error on my side :

public override bool Hold { get => base.Hold; set => base.Hold = value; }

    private void Awake()
    {
        Hold = true;
    }

@weak dove

[tired elk]

I suppose it's some Unity Serialization shenanigans

I configured mine and got the error only in unity as well

[thin aurora]

Then you defined that property twice and caused the backing field to be generated twice

This has been a bug in Unity since like 2016

[swift falcon]

so i have an issue, was wondering if anyone could help me out. i have a 2d character which the only way it can move by design is by shooting the floor with its gun. I want it to launch the character in the oposite direction the gun is pointing. i am using the arrow keys to rotate a pivot which has the arm and gun attached. I have an object on the gun called BarrelEnd. I am adding a force to my rigidbody of the character based on the difference between the position of the character and the 'BarrelEnd', but as its rotating the location of the barrel is not changing in the editor, even though it appears to be moving in game.. any obvious reason why this is happening?

[tired elk]

I tried recreating what they have (i suppose), with an interface, a base class that inherit from MonoBehaviour and implement the interface, then having a class inherit the base class. I attached the inheriting component on a game object and that's when the error appear in Unity console. So idk

[thin aurora]

You can fix it by naming your properties better and/or using namespaces. You should probably do the latter in general

[weak dove]

I've tried restarting the editor several times, didn't make a difference

[thin aurora]

See above message

[weak dove]

What's wrong with the property name?

[thin aurora]

It is a bug in the serialization pipeline and either renaming your properties and/or using namespaces fixes it

The fact that you used the same name twice in the same (global) namespace

[tired elk]

It's implemented from interface, shouldn't it be this way ?

[weak dove]

But I'm not trying to have different variables. There's an interface IInteractable that has a Hold variable. Every class that inherits from this interface should have this specific variable.

[spark flower]

hey

im trying to write something and this keeps popping in

and messes things up

[swift falcon]

nevermind did it 🥳

[tidal rapids]

Hey guys im wanting to use Unity CCD to do something with a level editor that will allow players to make a level, push it and then load others at runtime of course. Does that sound like its possible using this or will I need to use something else?

[rocky helm]

Is var script = someTransform.GetComponent<Script>(); in any way slower than doing Script script = someTransform.GetComponent<Script>();?

[steady moat]

No, it is not.

[leaden ice]

it's literally the same thing

[steady moat]

It is only preference

[rocky helm]

Alright

[leaden ice]

You may notice when you do that, if you mouse over var it will say Script

[steady moat]

Personnaly, I hate var. It reduces readability

[primal wind]

Honestly i'd recommend to always use the type instead of var unless you need var for some reason

[leaden ice]

I use it only when the type is obnoxious

like

var dict = new Dictionary<GameObject, Tuple<int, float, bool>>();```

[steady moat]

My eyes

[leaden ice]

yeh

[primal wind]

they burn

[steady moat]

I tried to not use tuple. Better to have struct.

[leaden ice]

agreed

but this was a contrived example

[elfin tree]

I'm trying to make a 'lore entry' system for my game. Nothing too unique.
Entries will be unlocked and have a path in a tree.
I was thinking maybe each entry has a path, and when it's added, the path is either created in UI or added to the an existing sub-section.
I'm wondering the best way to do this and if resources for this exist out there?

[steady moat]

No worries, I get it

[primal wind]

Some libs do have long class names

[robust dome]

or when i am too lazy to change it because VS autocompletet code 😉

[tired elk]

Is there a case where tuples are interesting ?

[steady moat]

I use them in like find the minimum or maximum in a list when I cannot use linq.

(int max, float value) max = (-1, float.MinValue);

[tired elk]

I think I used them only for a swap method, but appart from this, i don't have much knowledge on it

[steady moat]

Yeah, swap would be a good use case

[leaden ice]

I think the less prolific the type is in the codebase, the more appealing a tuple is

if it's literally used on 1-2 lines that's the sweet spot

[tired elk]

Ah, like a data structure that won't be used outside a function for example ?

[leaden ice]

yeah maybe a return type for a local function or something

[tired elk]

OK, thanks 🙂

[steep herald]

I have a varying number of instances of A, and I have a varying number of instances of B.

I want to store all the possible group configurations.

I don't want to store everything individually like A[0] maps to B[0], A[0] maps to B[1], A[0] maps to B[2].

What I actually want is to have something like
configuration 1 = A[0] maps to B[0], A[1] maps to B[1], A[2] maps to B[2].
configuration 2 = A[0] maps to B[1], A[1] maps to B[2], A[2] maps to B[0]
and so on, covering all the possible configurations.

Any idea?

[leaden ice]

do you actually need to store all permutations?

What's the use case here?

What are you trying to do

on a basic level you can generate all of these permutations with a nested for loop

[steep herald]

I have an arcade idle, the user serves popsicles to customers. Theres a mechanic with a platter, the platter contains up to 4 popsicles. There are up to 4 customers. The idea is to remove a step by autoawarding whatever will yield the best final results

[leaden ice]

foreach (Something a in A) {
  foreach (Something b in B) {
    Debug.Log($"Permutation {a} with {b}");
  }
}```

it kinda depends also if (A[0], B[0]) and (B[0], A[0]) are considered different or not

[steep herald]

I don't understand how. If I do the above, then it'll iterate through all of A, and it'll iterate through all of B so I can map all As to Bs, but it'll map things individually.

I actually need to calculate the sum that a configuration will yield. Say we only have 2 customers and 2 popsicles. Then the (A[0]-> B[0], A[1] -> B[1] ) configuration could potentially reward $100, whereas the (A[0]->B[1], A[1]->B[0]) configuration could reward $50.

By storing the configurations and their outcome, I can sort them to determine which outcome is best and then I can serve the customers based on that.

Does this make any sense?

[leaden solstice]

Sounds like you need some algorithm

[steep herald]

thank you so much

[dry sleet]

Hey guys,
I have a gameObject which is called Player, and it has PlayerId.
It instantiates 2 prefabs which are called Character.
And Player is Character parent. And it has access to both Characters. Also as I know child shouldn't know about its parent.
Does it make sense Character have a field which stores PlayerId ?

[leaden solstice]

Probably simple greedy algorithm can help you start

[fervent furnace]

graph algorithm

[leaden solstice]

Nah

[leaden solstice]

Bi directional reference is fine, if you can manage. You can inject player reference for its children

[dry sleet]

Could you give me a reason why it is fine ?

[leaden solstice]

Because it does the job 🤔
What gives you a restriction? If you want you can abstract your Player class so child only know IPlayer interface for example

[steady moat]

You can use the Dependency Inversion Principle as stated by others. Alternatively, you can use an Observer/Observable pattern.

https://en.wikipedia.org/wiki/Dependency_inversion_principle

An other approach would be to "extract" the player id in an other object. By example, PlayerInfo. Then both can use this object.

Personally, I would generalize the player id in something like character id.

[dry sleet]

Yup, I was using DI for injecting PlayerId into CharacterController but then I thought maybe it doesn't makes sense Character knows about its parent which is the Player. Then in some situation I was using PlayerId to raise an event which should be handled by corresponding Player (By message bus or event aggregator).

Then I've tried to omit PlayerId from CharaterController and instead Player knows about CharacterIds and based on that, handle events. But it looks kinda stupid I guess, not sure, looks like it makes things complicated. What do you think ?

I like the second approach but do you think it is an absolute rule which child shouldn't have a reference from the parent ? I'm always confused about it and not sure about the actual reason.

[dry sleet]

What do you mean by that ?

[steady moat]

Instead of having a PlayerID inside the character, you could have CharacterID which correspond to the PlayerID. The player would then push his PlayerID

[steady moat]

In video game, most of the time, the clean code aspect is thrown out to some extends. This is necessary. My advice would be to not think to much about.

If you still want to make things clean, I would suggest that you never have direct bidirectional reference (No interface in between) and reduce as much as possible indirect bidirectional reference (Interface/Events). When you respect those rules, you inherently increase the modularity of your application.

To make such application, you need to heavily subdivide your behavior in such a way that the dependency graph is a tree. Doing so would result in a really more complex code though and might not be suitable for every team/person. This has the same dynamic that cohesion/coupling has.

[dry sleet]

Got it, thanks.

[lean sail]

I also like to think: you can attempt to make your game as modular as possible but theres a certain point where you definitely wont extend a feature

Over engineering and getting the same result as a "less clean" solution has no affect, the only thing that matters is "will people pay for this"

[modern creek]

I'm looking for some input on selecting a solution path for saving/loading game files for a new project.

I'm building a game with a "persistent" world. Each map screen (think "chunk") is generated when needed and contains some number (currently about 20x10 = 200) blocks - these blocks can be destroyable and contain resources, fixed terrain, or other navigation (ie, move to the adjacent chunk). You can travel NESW and Up/Down from chunk to chunk.

Should I just create my own file format? Use something like MessagePack/Protobuf to read/write byte arrays? Store it in json?

I'm worried about long term save file size as players build up their world.

[pure cliff]

Is this data mutable or immutable once "rendered"? Im assuming the chunks are being lazy loaded as needed, and then you wanna cache em for faster future loading?

mutable: Youll wanna make your own custom data format, because I dont think protobuff supports specific point save/editting, you'll wanna have the ability to discretely modify specific points in the data for mutations that occur in game (IE in Minecraft, you dont wanna have to resave the entire chunk because you broke 1 single block, every block)

Immutable: Protobuf should be solid

You could potentially store the "original" via protobuf, and then use a secondary "mutations" file that stores a sort of "diff" of the chunk from Old->New, so you apply the original, then apply the diff to produce the expected output.

Could also have a background process that periodicially goes and applies the diff to the original and resaves the original (and disposes of the diff) to improve speed.

[austere oriole]

Hey everyone and anyone.
Like I probably already asked before, I'm trying to make a character creation scene in unity. Right now I want to start simple to get to know how to do it, by just starting with "gender" option, male or female and a "name" textbox. I got the default male model and female model from mixamo. So UI is a button or dropdown "gender" that opens the male or female option and a textbox where you can write your name. A renderer is active that shows the model you've chosen. When you press "create character" I want the chosen model to be visable as the player model and the name somewhere saved so I can use it whenever I want in scripts.

After I've done that I want to start adding things like hairstyle, haircolour, skincolour, face variants and so on.
Can anyone push me in the right direction for this please?

[leaden ice]

a custom binary format is going to be the most compact, with MP or PB being a close second

JSON is probably not recommended.

[modern creek]

Yeah, the only reason I'd consider JSON is debugging lifecycle. byte[] is hard to read - I'd have to make custom tooling to look at them

Maybe I should make two adapters - save both files, turn off the JSON adapter for production

[leaden ice]

you could have a toggle - exactly

though

Protobuf has pretty good tooling

[modern creek]

Cool, I'll check it out. I'm not an expert in protobuf - I've used messagepack this last couple years

[leaden ice]

and low risk of the binary format/formatter itself containing bugs

messagepack is also good

[modern creek]

Not sure I'm still on the MP bandwagon though because of all the aot/jit issues with android

(I'm assuming I'll have the same with protobuf though)

ie - android doesn't support JIT compilation so I have tooling to generate and include messagepack CS files in my android builds.. it's a bit of a pain in the ass and was a huge timesink figuring out this last year (probably 100+ hours just related to that)

[leaden ice]

you'll need to do something similar for protobuf

[modern creek]

bah

[leaden ice]

but it shouldn't really take 100 hours 😯

[modern creek]

protobuf is more widely used from my understanding

[leaden ice]

It is - using it right now at work in fact lol

[modern creek]

the 100 hours was .. the educational "journey" for learning all about the nuances of the android/google environment and getting my builds working with my ci/cd tooling

[leaden ice]

sounds like much of that knowledge can be reused?

[modern creek]

it was.. painful.. there were very limited resources out there for my specific usecase

yeah, i "have it" now so I could reuse it

[leaden ice]

Honestly though unless you're making changes to the PB a LOT, I would just leave the source generation step as a manual step

[modern creek]

if protobuf is likely to be similar "just different" then I'd probably just default to MP, but it would be nice to have protobuf knowledge in my personal repetoire

perhaps - there's some stuff i like to shove in my POCOs/DTOs that i had to do a little bit of backflipping for (like structured logging integration, some overrides, etc) but .. i could probably get away from that by having another poco layer without the dependencies.. ie, have a "pure" poco that's MP/PB/JSON consumable and then another POCO on top of that that just contains a reference to the smaller POCO with all the extensions and custom stuff I want to have in them.....

sigh, real coding is complicated

@leaden ice are you using PB in a unity project? any "gotchas" you've found?

[leaden ice]

not unity no

In Python and Go actually

[modern creek]

seems like there's solid C# support

[leaden ice]

I think the way PB works with assemblies and namespaces in C# is a little weird from what I heard but I haven't really used it with C#

I think you get options for namespaces etc in the generator so it shouldn't be too bad

[modern creek]

it seems fine? looks like you just define your message in .proto files and there's some tooling in .net to map your data to those messages

I'll probably stick with MP.. i suppose there's no reason to reinvent the wheel here.. I suppose I don't really have any problems with MP, just a little bit of remembered pain from onboarding it all.

Then as far as this project is concerned, I'll probably make some sort of monolithic save file with all my POCOs and just serialize the entire thing to byte[] or json and try to keep the size of it down.. like I probably don't need to track all the details of every block - like if someone's hit it 50%, I don't really need that.

This probably means I need a separate save file POCO from an in-game POCO.. ie:

public class SaveFileBlock // MP object
{
  [Key(0)] public BlockType BlockType {get; set;}
}
public class InGameBlock // Hydrate this from the SaveFileBlock
{
  public BlockType BlockType {get; set;}
  public int CurrentHP {get; set;}
  ... etc ...
}

[leaden ice]

one thing to think about - I assume this is some kind of minecraft style game? - if the player can have multiple save files, you might want to store metadata about the save somewhere in order to display the save in a list of saves

[modern creek]

yeah

[leaden ice]

you wouldn't want to load the whole world data in order to display that list

[modern creek]

my save file MP POCO would be something like

public class SaveFile
{
  [Key(0)] public DateTime LastSaved {get;set;}
  [Key(1)] public string SaveFileName {get;set;}
  [Key(2)] public PlayerPoco Player {get; set;} // the bulk of the data
}

oh wait, i see what you're saying.. hm, yeah

so something like

[leaden ice]

So what I do sometimes is I'll bake a header into the save file

so you can just read the header bit and ignore the rest

[modern creek]

public class SaveFileMetaData // tiny file
{
  [Key(0)] public Guid Guid {get;set;}
  [Key(1)] public string SaveFileName {get;set;}
  [Key(2)] public DateTime LastSaved {get; set;}
}
public class SaveFileData
{
  [Key(0)] public Guid Guid {get;set;} // matches guid in metadata
  [Key(1)] public PlayerPoco Player {get;set;} // bigass byte[]
}

could probably even show file size (on disk) in the metadata

[leaden ice]

so IDK how it works in MessagePack but a quick example with json would be like:

HeaderData hd = new HeaderData("Save 1", "Gary Peterson", DateTime.Now());
string headerJson = JsonUtility.ToJson(hd);
string gameDataJson = JsonUtility.ToJson(saveData);

filestream.Write(headerJson);
filestream.Write(gameDataJson);```

then the save file parser can read the header part and ignore the rest to grab the metadata only

[modern creek]

don't you have to read the entire filestream though to just read the metadata?

[leaden ice]

nope

not if you are using filestreams

[modern creek]

ah you could read byte by byte until you've got what you need?

[leaden ice]

exactly

[modern creek]

cool

[leaden ice]

Another option is a separate file which has data about the other files.

But that's annoying because you can have all kinds of issues

like keeping them in sync

[modern creek]

aye, or storing the metadata in playerprefs even

[leaden ice]

yeah

they all have issues like if something gets corrupted or a user manually moves or renames files

[modern creek]

yeah, the issue that I forsee being the big one is what do i do with invalid data because features have changed

like, i'll probably have to put some versioning in the files, make an effort at never deleting/renaming fields, etc

pain in the ass stuff

[leaden ice]

yeah you'll need versioning

[modern creek]

if a user manually moves/renames files, well, they're on their own

[leaden ice]

the header section is a great place to put a version number too

for the save file format

[modern creek]

yeah.. and then i'll include some stuff in the save file hydrator that migrates data if it reads older versions

[leaden ice]

of course the header format itself could change but you'll maybe commit to making only additive changes there

[modern creek]

anyway, that's future-me problems, i'm still very much in prototyping, but this is good stuff to think about ahead of time.. i still encounter some of these problems with space game and have a lot of dangly-data-appendixes in the system

like i found out sort of the hard way that serializing/deserializing enums in unity is ... a minefield

I have this cutscene system where the writers can write cutscenes on the admin tool and the cutscenes are delivered to the clients via messagepack.. but it's allllllll enums. I removed a couple of old values that we didn't use anymore and it fucked up every single cutscene in the database - the wrong images were being shown, the wrong music was playing, the wrong props were being displayed, the wrong animations were playing... what a disaster day that was

[leaden ice]

does messagepack have an option to serialize enums as strings instead of ints?

[modern creek]

yes, but .. I don't 🙂

the cutscene data represents the largest chunk of data we send to clients.. back before I was versioning it and caching the cutscene data on the clients, every time a client would connect they'd get the entire cutscene database.. even serialized to byte[] it was like.. 30mb?

caching it solved that problem almost by itself but still, new client installs need all that data.. so.. serializing a ton of enums as strings would bloat it pretty badly

data looks like that

[leaden ice]

then you need to be careful about changing enums destructively and versioning the format whenever you do

[modern creek]

yeah, that's one way - my new way of handling enums is to manually assign the underlying int (and never change it)

like this

[leaden ice]

right I call that "being careful about changing enums 😉"

[tribal gust]

i am currently doing the unity junior programmer course, i've completed till create with code - 1, just wanted to know if its worth the time and effort learning from that course?

[modern creek]

oh wow I thought I was yapping on in #archived-code-advanced .. oops

[modern creek]

In general your best educational path will be to "do" - make apps, try to do things, and supplement that with the courses. A lot of knowledge is out there, but imho it's hard to retain it until you're actually trying to build something. Just passively watching a course and even taking notes is not really great for retention and deeper understanding.

Start with a simple game (like pong, pacman, donkey kong, happy color, etc) and see if you can get it all working. You'll find pretty quickly that you're unable to do something pretty basic - come to discord for help, and watch the videos and do the courses in your non-working time

[tribal gust]

i see

thanks for the advice

[vale cradle]

there's a way to see FPS in exported game?

[leaden ice]

sure - add a UI element and display it there

you can also attach the profiler, or possibly use utilities included with your GPU (like nVidia overlay)

[vale cradle]

another question, and i know that is no the topic

dou you know about post processing?

[leaden ice]

go ask in #💥┃post-processing 😉

[vale cradle]

can you help me if i ask there?

[leaden ice]

I won't commit to anything

[still sphinx]

hi guys, i wonde can players save files from game asset to their desired location, forexample backgrounds of my loadscreens i want to let players save and use it wherever they want ?

[leaden ice]

Nothing stopping you from allowing this, sure

[still sphinx]

is there any permission i request from player like mobiel os's or just give him a button and save ingame folders ?

or may i open the folder automaticly

[leaden ice]

yes some platforms requires special permission to access certain parts of the filesystem

[prime acorn]

Hey I was trying to get ads running and ran into this error, anyone know how to resolve that?

[still sphinx]

thanks

[prime acorn]

This only happens when the build settings are set to android, what is the platform I wanna build on though

[leaden ice]

do you have all the android SDK stuff installed?

[prime acorn]

yes I have

[elfin tree]

I'm trying to make a 'lore entry' system for my game. Nothing too unique.
Entries will be unlocked and have a path in a tree.
I was thinking maybe each entry has a path, and when it's added, the path is either created in UI or added to the an existing sub-section.
I'm wondering the best way to do this and if resources for this exist out there?

[prime acorn]

these are the build settings Im trying to use

I made a new project from scratch so there is 0 code from me in it whatsoever, it just fails installing the package in the first place

[indigo arrow]

I'm tryna make use the animator component for a state tree for a boss im working on. Issue is, the animation's OnStateUpdate() is called every frame, rather than like FixedUpdate, and no FixedUpdate() alternative exists as far as i know. How would I achieve this?

[indigo arrow]

nevermind

[hexed gulch]

can someone help me with this question

[viscid bane]

I don't knw where to post this, but what is this and why does it keep showing as errors? I just want to remove it

the little red thing on the left side

[simple egret]

It's the Git integration in the IDE. Here it tells you that one or more lines have been removed compared to the last version of the script you committed.

[viscid bane]

I've never seen this until I reinstalled Visual Studio on this

[simple egret]

Latest update feature, most likely. VS Code has these indicators too, but they were added earlier compared to VS

[viscid bane]

how do I turn this off

[rocky helm]

Shouldn't raycasts ignore the collider they start in and/or the collider of the object the script is on?

[simple egret]

Somewhere in the settings...

[viscid bane]

I have

it's not helped

[somber nacelle]

only if you enable that behavior in the physics settings

you should still use a layermask even with that setting enabled though

[viscid bane]

I can't find whatever any of this is

https://devblogs.microsoft.com/visualstudio/line-staging-interactive-staging/#:~:text=If you need to switch,support” and toggle the checkbox.

[rocky helm]

I have multiple npcs with the same layer who should get in the way of each other so I believe I can't use layers for this, also I couldn't find a setting for that in Physics settings, but I found this in the API "Raycasts will not detect Colliders for which the Raycast origin is inside the Collider."

[viscid bane]

I can't find any more info on this apart from this one page, so I can't disable it

[somber nacelle]

and are you sure that the raycast origin is inside of the collider?

[rocky helm]

Oh dam, it is on the collider. But I still couldn't find that setting if I need it to not hit the transforms collider

[somber nacelle]

turns out it's a 2d only setting and 3d only has a semi equivalent setting for mesh colliders 🤷‍♂️
but it's set to the behavior you want by default anyway

[rocky helm]

Odd it wasn't working for me then, anyways I just move the collider so that the ray start position isn't on the collider but in and it works :p

[spring creek]

When you commit the change, it will go away. Sorry that's all I know about it

[viscid bane]

That’s a lot of scripts that have that

[lean sail]

the page you linked says how to disable it 🤔

[viscid bane]

There is only one page on the internet that talks about it, and when I follow it, nothing it says is there

I restarted and I will try again because maybe it was a glitch

[lean sail]

that feature is no longer a preview, i think this is the one u are looking for now
Tools > options > text editor > general: Track changes
Though if a lot of scripts have this, are you commiting your changes properly?

[spring creek]

So you have a lot of uncommitted scripts 🤷‍♂️

       ```
I'm I have 2 rooms, one in a prefab that gets instantiated to `newRoom`, and one kept track of in `curRoom` (a variable in the class). I just want this function to slide the new room onto the screen and slide the old one out and destroy it, in about 1 second's time. For some reason, this instead takes about 0.1 second, and at the start the room get teleported to (-.99, -.19, .01) then the new room slides to the center while the old room slides about 1 quarter unit diagonally... anyone see what I could be doing wrong? Is there a better method to this?

[hexed tiger]

Hey I made a jetpack code and for some reason it doesn't work the same. When I'm playing maximized it works perfectly, but when I play focused or on the exported game, it works incredibly buggy, playing audio and particles but not doing the jetpack thing. If anyone knows how to solve this sort of bug where it plays well somewhere and wrong somewhere else, please help me 🙂

[lean sail]

pretty hard to suggest anything based on this alone, could be FPS related, could be values that existed in your editor but not a build. You'd probably have to show what you did

[umbral agate]

What do you mean?

[edgy ether]

does anyone know how to set a sprite from a sprite atlas's texture to be readable via script?

[cursive hollow]

Anyone know why the camera just shows blue when I spawn in the character?

[lean sail]

i dont specifically see anything thatd cause this. make sure you save and rebuild incase, but you can also debug in builds to see if there are any differences/errors. You'll just either have to print the logs to some text area on screen, or look at the log folder.

[hexed tiger]

Okay...

[sage latch]

You're camera is probably too close on the z axis

the default z is -10

[hexed tiger]

There aren't errors. It just doesn't execute properly, might it be because screen resolution stuff?

[cursive hollow]

I’ll try both

My main problem is that it doesn’t have the problem when it isn’t a prefab

[lean sail]

and you checked there arent errors in the log folder? Also still you can debug to see what values are different/not expected in a build compared to in editor

[sage latch]

Is the camera in the prefab or do you spawn it manually?

[hexed tiger]

Ima do a new build and try

[cursive hollow]

I spawn the camera with the player

The camera is a child of the player

[sage latch]

With code or is it already in the prefab?

[cursive hollow]

Already in

[sage latch]

Ok, then make sure the camera's z is -10 or something similar

and the player is at z=0

[cursive hollow]

Hey there i have problem with my Main Menu Script i followed a tuorial but i cant press ESCAPE button to open my pausemenu. Nothing happens, if i hardcode

 the escape menu works. What is my Problem?

My Input Manager
```cs
using UnityEngine;
using UnityEngine.InputSystem;

public class InputManager : MonoBehaviour

    public static InputManager instance;

    private PlayerInput _playerInput;

    public bool MenuOpenCloseInput {  get; private set; }

    private InputAction _menuOpenCloseAction;

    private void Awake()
    {
        if (instance == null)

            instance = this;
        }

        _playerInput = GetComponent<PlayerInput>();
        _menuOpenCloseAction = _playerInput.actions["MenuOpenClose"];
    }

    private void Update()
    {
        MenuOpenCloseInput = _menuOpenCloseAction.WasPressedThisFrame();
    }
}```
This is my MenuManger
using UnityEngine;
```cs
public class MenuManager : MonoBehaviour
{
    [SerializeField] private GameObject _mainMenuCanvasGO;

    public static MenuManager instance;

    private bool isPaused;

    private void Start()

        _mainMenuCanvasGO.SetActive(false);
    }

    private void Update()

        {
            Pause();
            print("Pause");
        }
    }

    #region Pause/Unpause Functions

    {
        _mainMenuCanvasGO.SetActive(false);
    }
    #endregion
}```

[cursive hollow]

Still nothing

Thinking I screwed something up with the spawner

[hidden flicker]

What do most games use to deal with ramps

Like what method

Because those things are horrible

[cursive hollow]

It’s loading the camera this time but it’s not showing the player sprite now

[cursive hollow]

What’s your problem

[hidden flicker]

Well, slope bouncing & slower speed mostly

There are other problems I'm sure but I can't think of them

Unity 3D btw

[cursive hollow]

I’m still pretty shit at programming slopes so I would look up a tutorial

Make a raycast checking for a slope or not and then mess with your code for that

[plucky fulcrum]

Trying to make doors work with hinge joint component, normal swing doors work fine but a door that opens down like an oven door doesn't work

anyone know how to make an hinge joint door work with open down

[sage latch]

Did you enable the new input system, or set them both to work?

[karmic dune]

both to work

[sage latch]

You have to enable the InputAction

[sage latch]

(InputAction.Enable())

[spring creek]

What wasn't clear? If you have a lot of scripts with the red triangles, then you have a lot of scripts that haven't been committed

[viscid bane]

No I don't understand

[spring creek]

Did you try this though?
#archived-code-general message

[spring creek]

Which part?

[viscid bane]

committting

[spring creek]

Ah... you are using version control, right? If not, do so

Committing is saving in version control, like git

[karmic dune]

What you mean? Can you show me example on my code?

[viscid bane]

I'm not using Git for this project

[sage latch]

In InputManager:

private void OnEnable()
{
  _menuOpenCloseAction.Enable();
}

private void OnDisable()
{
  _menuOpenCloseAction.Disable();
}

[viscid bane]

or version control

I've not really looked into it

[hidden flicker]

you're sure the axis is correct?

To open down you'll want the joint set on the Z axis

[plucky fulcrum]

yeah if i have the use gravity on rigidbody then it just falls down otherwise it doesn't move

[hidden flicker]

Hmmm

Yeah not sure

[karmic dune]

using UnityEngine;
using UnityEngine.InputSystem;

public class InputManager : MonoBehaviour

    }

    private void Update()
    {
        MenuOpenCloseInput = _menuOpenCloseAction.WasPressedThisFrame();
    }
}```` still my esacpe not working

[sage latch]

Try putting a Debug.Log to see if the value is ever true

(in InputManagers Update)

[spring creek]

I wouldn't start a flappy bird clone without version control honestly. Next to the debugger, it is the most important tool in coding.

But either way, try what bawsi said

[lean sail]

You should look into it. If you dont, then dont be upset if 1 month into a project something gets corrupt and you have to start over from scratch. Or 3 months.. or a year

[viscid bane]

try 3 years

[obtuse frost]

Deleted my post in the beginner chat to post here instead without cross-posting since this may be a more appropriate channel.

[lean sail]

You've been coding for 3 years and never learned version control? You REALLLLY should know it by now

[obtuse frost]

I'd die without git lmao

[viscid bane]

I've been coding for longer, but not used version control

[somber nacelle]

just for that project

[spring creek]

That is an issue.
Like I said, it's one of THE most important tools in coding.
I would honestly stop everything and take the 10 minutes to learn it and set it up

[viscid bane]

alright

[spring creek]

There're guis to make it dead simple

[obtuse frost]

Just having the ability to branch off for experimentation is wildly helpful

[lean sail]

Even if not branching, just saving your work is a must

[obtuse frost]

And being able to roll back to more stable foundations/at least have a way to look at your code from that point in time

[hidden flicker]

How do most games handle slope movement?

This shit isn't working
https://www.youtube.com/watch?v=xCxSjgYTw9c

[lean sail]

This guys tutorials only work for the purpose of the video, I wouldnt follow a single thing from him

[hidden flicker]

Ok thank you

[obtuse frost]

I've been learning this the hard way lmao

[hidden flicker]

Yeah

[lean sail]

Let me see if I can find a video I saw linked covering it properly

[obtuse frost]

Right now I'm trying to design a controller that would support basically Tribes-esque movement and boy howdy am I extremely lost lmao

[hidden flicker]

Thank you :)

Also IDK if you saw my earlier message but I'm having a problem where my player moves much too fast if they aren't selected in the inspector

[obtuse frost]

Do you have serialized or public variables that may be drawing from the inspector fields instead of the script or vice versa?

[hidden flicker]

All variable values come from inspector fields, but deselecting it shouldn't cause problems...

At least it never has before

[lean sail]

https://www.youtube.com/watch?v=s-99Z_W8bcQ

This was a pretty good one, u could also just use the kinematic cc on the asset store

[lean sail]

The only time I've ever had something like this happen was a unity bug when my unity crashed overnight and I didnt notice. Then opening it up again had the sameish result. Maybe restart your unity

[hidden flicker]

I have

:(

[carmine cloud]

Why is InputAction.CallbackContext so bloody useless... Why does it not just let you know you clicked on a ui object? Seriously unless I'm missing something the input system is purposfully stupid.

[lean sail]

Yea I wouldnt have a clue otherwise. I'd start by debugging what related values are like your move speed or anything else. Maybe try making a new character and see if it happens on that one too. Really hard to say without knowing the exact specifics of your project

[somber nacelle]

why would the input know about your UI objects? what you want is the EventSystem which is what handles translating input to interacting with the UI

[carmine cloud]

if you ask the eventsystem from the input system EventSystem.current.IsPointerOverGameObject() it will give you an error

[somber nacelle]

and what error would that be?

[carmine cloud]

it's not referencing the correct frame

[somber nacelle]

wtf does that mean?

[spring creek]

Is that word for word what it says?

[lean sail]

You should probably just follow a tutorial or written guide on this if you dont know what's happening

[carmine cloud]

Calling IsPointerOverGameObject() from within event processing (such as from InputAction callbacks) will not work as expected; it will query UI state from the last frame

[obtuse frost]

Interesting, this video seems to take roughly the approach I was thinking: compute the camera movement then implement movement as a result of that.

[carmine cloud]

and it absolutely can cause an error in behavior

[lean sail]

It goes into a lot more, at least if I'm remembering correctly like slopes and moving along a wall instead of just being stuck at an angle

[obtuse frost]

Yeah in terms of projection onto inclined surfaces and such, which is currently handled by the CharacterController element for my current implementation

[hidden flicker]

Uhh

I'm doing what it's talking about but it isn't quite working

[lean sail]

That is like as vague as you can be

[hidden flicker]

Sorry you're right lmao

Projecting the movement onto the plane of the ramp normal

[modern creek]

Are there any built in components in Unity.UI for pinch+zoom scrollrects?

[hidden flicker]

Ok, I just - here's the movement code. I know there are errors and redundancies. Help it slope good
https://hastebin.com/share/mekoyoyino.csharp

[obtuse frost]

I don't know about built-ins, but this video shows a simple way of using the new input system to just calculate the change in distance over time of two touch points: https://www.youtube.com/watch?v=jKVTKKDr7Ak

[cursive hollow]

Ok I found my problem

When I spawn in the player character the camera spawns on the same z axis coordinates no matter what I input

How do I fix this and make it spawn further away from the player

[sly vapor]

spawns as in your instantiating it?

[cursive hollow]

Yes

[low horizon]

how can i copy a struct that is on a scriptable object class?
internet tells me structs get copied by default and classes are referenced

but when i change the value of struct in the scriptable object the one i was supposed to copy also changes

[rigid island]

its making a copy?

whats the struct contain ?

[cursive hollow]

So does anyone know how I can fix my camera

[rigid island]

duct tape

[obtuse frost]

Since it doesn't look like my question is gonna get much traction is there any chance someone knows of good resources for designing a character movement scheme in depth with all the physics and such?

there aren't any classes or someting in the struct

[rigid island]

are you changing the reference type ? cause that doesn't make a new copy

List<PositionDirection> for example

[low horizon]

    public override void InitializeSkillData(WeaponSkillDataBase skillData)
    {
        base.InitializeSkillData(skillData);
        dataStruct = ((ScytheSwingSkillData)skillData).dataStruct;
    }

i get it like this

[low horizon]

oh

lists don't make copies?

that was the problem i guess

[somber nacelle]

List<T> is a class therefore a reference type

[rigid island]

lists are reference type

[low horizon]

yeah i was changing lists

ohh

my bad

thanks

Is it illegal to bump a message from another channel?

[obtuse frost]

Speaking of bumping, sorry to do it so soon but I'd love some thoughts/advice on this: #archived-code-general message (alternatively some material on designing complex movement would suffice)

[sleek bough]

You can reference your question in another relevant channel if it became buried and some time passed.

[ripe linden]

Do coding bugs relalated to the input system go here or #🖱️┃input-system

[sleek bough]

It depends on specifics, is it a coding problem or a specific problem related to understanding how input system works.

[elfin quest]

alight then Bump! #archived-code-advanced message

[sleek bough]

When in doubt post entire question first ask later. (just don't cross-post)

[ripe linden]

The error is a method exception but my debug commands works so idk whats happening #🖱️┃input-system message

[ripe linden]

I mean is adding a link cross posting?

[sleek bough]

When your question is still visible, yes

[lean sail]

your issue is just likely networking related, the instance of the class not being found by the server for all other clients.

[elfin quest]

this is all on the server tho, I have an event just like it above it, that one wors well

[lean sail]

your null error indicates it is not working well.

if it works, then whats the issue

[elfin quest]

No, another event works well, nevermind it.

I just added a null check for this event and I'm getting the message "null" but It's clearly deffined no?

This null reference exception is from the subscriber

[lean sail]

if your delegate is null, you have nothing in the invocation list

aka nothing has done OnAuto += something

A common way to write that is just OnAuto?.Invoke(); You can use null conditional since its not a unity object

[elfin quest]

The problem here is the fact that it is null, why is it null?

I don't really wana check if it's null, I wana call it

[lean sail]

#archived-code-general message

[elfin quest]

But I can't put nothing in the invoation list because it is null

[lean sail]

you should look at some guide on how delegates work, or experiment outside of unity in a project you can run this quickly on

that is not how delegates work

[elfin quest]

fuck me and my retarded ass omfg

I got it xd

[lean sail]

maybe refrain from that language here too :p

[elfin quest]

Oh sorry. Look at what I missed, on the script that calls it

the "subscriber"

like it ain't the delegate missing, it's the whole ass script reference

[lean sail]

even though not neccessarily networking related then, this was still basically the issue then

the instance of the class didnt exist

[elfin quest]

y but the debug message don't differenciate between the delegate missing and the class refernce missing, so i got confused, sill mb, thank you for your help!

[somber nacelle]

you had two errors. the first was the characterAutoAttack object being null where you subscribe to the delegate. since that had been null nothing subscribed to the delegate hence it being null for the second error. always start resolving errors with the first one in the list, 9 times out of 10 it is the reason following errors happen

[eager wagon]

hi, i have a problem, i have a object that travels realy fast and sometimes pass the collider, what can i do??

[spring creek]

Using rigidbody based physics movement will probably fix it. Are you using transform movement?

[eager wagon]

yep im using transform movment

should i use rigidbody then?

[somber nacelle]

yes. depending on how fast it is moving you may even need to make sure the rigidbody's collision detection is set to continuous

and if it is too fast for that then you need to not move it as fast or do collision checks manually

[rain minnow]

manipulating the transform does not use the physics engine, therefore, the collision will not occur accurately when the object intersects the other object's collider . . .

[elfin quest]

Noty what I was refering to, but thanks for the advice!

[hasty plinth]

I have a question about the way I should aproach coding some pathfinding for my game

[eager wagon]

got it

[hasty plinth]

for the enemies spesifically

[eager wagon]

i think it souldnt be a problem

[eager wagon]

got it thx

[somber nacelle]

sure, but when you += a delegate it will not throw a NRE if it is null. so the NRE on that line could not have been referring to the event

[elfin quest]

ah, mb then, did not know that. I thought it has to do with the passed AutoInfo object since the errors started when i renamed the class, everything bugged out and then unity said, no script reference in this object because f*k u that's why xd

[hasty plinth]

I want the red enemy to choose the closest target to go to, but because there will be a lot of enemies, i don't want to calculate all the distances and find the shortest one for every enemy and for every frame.
How should I approach this so it isn't very resource intensive?
Also the squares in the pic will act as distractions and will pop on and off when the player wants. How should I inform every enemy when they acitvate and deactivate without being resource heavy?

(I don't want the specific code, just the way I should approach coding it)

[eager wagon]

there is something like pathfinding, its coll navegation i think

its a bit complicated but i think it should solve your problem

It's an Editor bug, ignore it.

[twin yoke]

ayt thx

[terse garnet]

Guys, can I buy some developer license or something so that the apps I create stop being picked up in windows defender as unknown app?

[rain minnow]

you can use a cast or overlap method to collect enemies within a certain range, then loop to find the closest enemy. this limits searching a collection of enemies to a given range instead of every enemy alive or in the scene (view)

an alternative is using a trigger collider that adds enemies to/from a collection when they enter/exit the trigger collider. then you run a loop to find the closest enemy

if you're worried about it being resource intensive, you can run the distance check (on the collection) on a timer or ping every X amount of frames or X amount of seconds. that way, you can increase or decrease X when ever you want . . .

[hasty plinth]

Should I use Coroutines to set the time limit for the distance checks?

or are there other methods?

[rain minnow]

you can use a coroutine but using Update should be fine. that'll give you more flexibility to stop/pause the searching and/or distant check code if needed . . .

[hasty plinth]

How can I have something in Update() that runs every x amount of frames?

[quaint rock]

count frames, and only do work every nth frame

likly more useful to do it based on time and not frames though

if ((Time.frameCount % 8) != 0) return;

[hasty plinth]

hmmm I have never heard about this. Where can I read more about it?

[quaint rock]

its just math, the % is modulos operator

gives the remainder of a divsion

[hasty plinth]

yes but the .frameCount

[quaint rock]

so like (n % 2) == 0 would only be true if n is divisiable by 2

[spring creek]

Unity docs has everything

[hasty plinth]

and wouldn't that be == 0 and not != 0 because we want every 8 frames?

[quaint rock]

also docs for unity things
https://docs.unity3d.com/ScriptReference/Time-frameCount.html

[spring creek]

https://docs.unity3d.com/ScriptReference/Time-frameCount.html

[quaint rock]

well no my example i was returning early

[lean sail]

well its returning if its not 0

[quaint rock]

so skip the rest of a function

[hasty plinth]

Oh yes my bad, I forgot how to read code

[quaint rock]

like if ((Time.frameCount % 8) != 0) return; was saying if its not divisible by 8 return and do nothing

[hasty plinth]

thanks a lot, I really didn't want to go through the hastle of doing everything with Coroutines

[lean sail]

i was corrected on this now i must correct others 🙏 it is the remainder operator in c# so it can return negative values

not in this case, but in general

[quaint rock]

for this purpose with positive inputs does not matter though

but yeah in general it does act different then say the same operator in like python

also @hasty plinth reason why you want it based on frames and not time?

like not do things thing every 0.25 of a second or something like that

[rain minnow]

sorry, afk. you can check the frame count but it's easier to do X amount of seconds . . .

just use a timer, when it's 0, run the method and reset the timer . . .

[hasty plinth]

Oh, no particular reason, I thought that maybe frames would be easier, but other than that no reason

How could I do it with time instead of frames?

[quaint rock]

make a float field, set it to how long you want to wait

every frame subtract Time.deltaTime from it, when it goes below zero call your logic and reset it to its original value

[spring creek]

You can reset to the original time - overage so you don't drop time too. It'll practically never be exactly 0 at the end of the timer, so it'll druft if you don't account for that.

It only matters when you reaaaaly need precision/regular timing though

For cooldowns, this would never matter

[quaint rock]

i said reset it, since its counting down from the total wait time

and the check is for below zero not zero

[spring creek]

Yes I know... what does that change for what I said?

When it goes below 0 (which it will, as you said) you get that amount and reset it to total wait time minut that below 0 amount if you need high precision. That's all I was saying

[quaint rock]

the overage would only matter over a very long time, and only if you care about very regular intervals

[spring creek]

Yes, as I said

[quaint rock]

but yeah you can just go back to orginalValue - overage

[spring creek]

It was just an interesting aside they may have wanted to know about

[quaint rock]

its good to mention depends on the use case

for spreaing some work out likely wont matter, but i could see it mattering for say a simloop for calculating states over a long time frame

though generally there you abstract thigns a little and start working with time slices

[spring creek]

I use it for a moba doing waves, and for a rhythm-esque (not quite music) game

[quaint rock]

like a project i used to work on, would on startup compute what stats should be as if the game was always running

[spring creek]

That's smart

[quaint rock]

yeah its not quite perfect, but more then close enough

not pefect since am not running the full NPC behaviors, but each one has on how long it normally takes and what stats to adjust. so the simloop can figure out which ones to execute and how things are effected for the time between the last save and now

[hidden flicker]

How can I set this line:
"moveDirection = transform.forward * Input.GetAxisRaw("Vertical") + transform.right * Input.GetAxisRaw("Horizontal");"
to account for slopes, and project onto a plane that is parallel to the slope it is on, using normals?

[dense tusk]

ahoy lads. i'm messing around with dialogue, and i was wondering what might be a good method for managing events that can change options in either dialogue, or within the game, such as giving the player an item or unlocking a room. any suggestions on what i can look into?

[rigid island]

Have you seen Ink before?

https://assetstore.unity.com/packages/tools/integration/ink-integration-for-unity-60055

[dense tusk]

i've been directed towards it before with some of my first questions regarding dialogue, but i'm a little apprehensive about learning how to use another software as of now. plus, i want the challenge of learning how to make a system from scratch, so i'm trying to avoid it anyways.

[runic cave]

ah, a masochist

[dense tusk]

exactly

[rigid island]

wdym learning another software ?

its inside unity , the only thing to really learn is the markup and how it can trigger functions in your script

🤷

if you wanna do your own system then look at scriptable objects

or using json ?

[rich leaf]

Hey i have a question about tilemapping. In my TilemapManager script, I have this as a test:

    private void Update()
    {
        Debug.Log(groundTilemap.cellBounds);
    }

Which keeps spitting out

"
Position: (-17, -11, 0), Size: (29, 28, 1)
UnityEngine.Debug:Log (object)
TilemapManager:Update () (at Assets/Tilemap/TilemapManager.cs:35)
"

From the documentation, it appears like unity automatically resizes the tilemap depending on the size/contents you have painted in the tilemap. However, when i add more opjects to the tile map (ie expand the area), this debug message is not changing. What am I misunderstanding about the tilemaps?

I've also loaded another scene with a tilemap (which is smaller in terms of # of tiles painted) and it returns the same message

[compact spire]

So scriptable objects don't appear to have a name field. Is it possible to do direct comparisons between SO's? Particularly, can I use an SO as a dictionary key?

[dusk apex]

They aren't game objects but other type of assets. What in particular are you trying to determine by comparing names?

[lean sail]

This would basically be asking if you can use a class as a dictionary key, so yea should be fine 🤔

[compact spire]

@lean sail I thought it might be something like that, I wasn't sure if there were some special comparison operators built into SO's.

[rigid island]

are you referencing the correct tilemap?

[rich leaf]

yes

Im sorry lol but Unit has the worst documentation i have ever seen

unity*

[lean sail]

i assume you havent seen much of anything else then

[rich leaf]

i have seen plenty

[rigid island]

the tiles/tilemap can be better but its not that bad

[cosmic rain]

Donno. In my opinion unity docs are pretty good. And I've been working with C#, C++, python, unreal engine and some other docs.

[lean sail]

just wait till you try to use a new tool and the docs are quite literally just the existing method names and thats all.

[rigid island]

just tested it and its accurate on mine

[cosmic rain]

Yeah, I agree about the packages docs.

[rich leaf]

Which version are you on?

[compact spire]

@dusk apex I have a mutable set of data per SO, Was just trying to think of a way to look it up without having to wrap those in another class and then use a string as a key.

[rigid island]

me ? 2021 on this one but don't think version matters...the code is the same.

[SerializeField] private Tilemap tilemap; void Start() => Debug.Log(tilemap.cellBounds.size);

[rigid island]

@rich leaf if you made the bounds big already and you see through code it doesn't shrink
you click the Tilemap 3 dots

[rich leaf]

After i clicked compress tilemap bounds, its only printing (0,0,1) now

I painted my tilemap using a game object brush, would that make any difference?

[rigid island]

probably since they're not technically part of the tilemap

[rich leaf]

Whys that?

[rigid island]

they're gameobjects not tiles

@rich leaf what exactly do you need it for ? you can probably place 2D invisible placeholders if you want matching size

[rich leaf]

Im confused on what the problem with this would be . Why are they not considred tiles if there is a built in brush for this in unity?

My long term goal is to serialize the tilemap data so i can save it to a file.

[rigid island]

then you would save the gameobjects /type and their placements (pos,rot,scale)

[rich leaf]

Game is 3D using a 2D tilemap for the floor

[rigid island]

its just an extra quirk / addon unity decided to add gameobject brush, it works with tilemap for the grid but its not part of the tilemap

its in the name GameObject brush not tile

[rich leaf]

Yes, but is there no way to utilize the tilemap to save these positions?

Like what was the point of them adding this brush capibility if it cant do that

[rigid island]

to snap to grid 3D tiles with ease?

they're not tiles tho lol

like in the code

[rigid island]

#archived-code-general message

is each "tile" gameobject type an enum ? or scriptable object? just save wat it is and transforms.. then recreate it on load

[rich leaf]

So essentially just use the tilemap to paint the scene and thats it?

[rigid island]

pretty much

nothing to special about tilemap unless you're using tiles it just saves you manually making grids through code

[rich leaf]

Ic

Thank

[night harness]

Could they not just use Tile.gameObject or am I misunderstanding

[rancid frost]

Does unity limit your fps?
I am literally only dispalying 1 sprite with a sprite renderer, the max fps (top left) is 3000?

shouldnt it be more?

[pure cliff]

Im trying to figure out a "clean" way to solve a bit of a puzzle, and Im not sure how to approach this.

I ideally would like an easy way to attach some form of variable/modifier to an instance of an AnimationClip, to indicate a specific frame, and specifically get "how much time does it take to get to that frame".

not a keyframe event mind you, this is info I need before I have even played the animation.

Effectively, I need some way to easily bake into a given animation reference that at a given keyframe, <thing> will happen.

In my case its for combat animations, I want to specify which keyframe is the "hit" keyframe, without having to play the animation and trigger with an event. This is because I am doing a whole bunch of logic way before the animation has actually played

Effectively speaking, I am going to need to synch up animations between 2 distinct entities that have their own animations, and I need to offset animation A so its "keyframe" will occur at the exact same time as animation B

So if AnimationA's keyframe is at 0.5s, and animation B's keyframe is at 0.6s, then I need to delay AnimationA from starting for 0.1s so they both hit their "mark" at the same time

[rancid frost]

you can use a stopwatch and measure the time?

[pure cliff]

I know the time but I ideally would like to do it by the frame, without having to keep jumping back and forth between animation <-> code, cause I have a lot of these animations and ideally if I could handle it within the animation reel itself thatd be better

Is there a way I can put some kind of "does nothing" marker on an animation, even just a special "does nothing" animation event keyframe, but instead of using it for firing off, I actually process the animation data and "fetch" the "timestamp" that event is set to

[rancid frost]

so essentially
when animation is playing...x seconds into animation play time...detect event...etc

[pure cliff]

no

I need to know this info before the animation is played at all

Im queuing up numerous animations that are gonna be playing out, and I need to keep them in synch dynamically

IE, player character swings sword animation, I have a "hit" keyframe on say, frame 7, enemy has a "I got hit" animation, but its actual "I got hit" frame is frame 3

I need the player's frame 7 to be happening at the same time as frame 3 of the enemy's animation

So I need to math out when to start each one before either of them have even played

[rancid frost]

I see

[pure cliff]

because in the above case, Id then go "Okay, I delay the enemy animation by 4 frames, got it" and then start

Is there a way to fetch the list of all animation events you have on an animation and parse their info and, specifically, get the exact time in seconds (float) that a given animation event is set to occur at?

cuz that seems like the easiest way to go about it

[rancid frost]

https://stackoverflow.com/questions/52722206/unity3d-get-animator-controller-current-animation-time

this might be of use

[pure cliff]

that doesnt seem relevant :x

I have a bunch of AnimationClip references in my script

[devout belfry]

can you add event handlers to the animations and when the player takes action, an event (associated with player animation) is created and any registered animations just handle the event?

[pure cliff]

nah cause its dynamic

Im pre-queuing all these animations seperately "ahead of time"

[rancid frost]

create a script which on awake gets all the keyframes of said animation and their time and store it in a dictionary

you can then use said list to measure the time between key frames

[pure cliff]

Is there some kind of "does nothing" keyframe I can add to an animation?

[rancid frost]

just add a keyframe

that does nothing lol

[pure cliff]

Id need a property to add it to

[rancid frost]

use a property u dont use

the z scale for example

or color

etc

[pure cliff]

Aight, looks like AnimationEvents are a lot easier to parse ngl, they even have the time value on em already mathed out, so I went with this for now

public static float AnimationHookTime(this AnimationClip clip)
{
    foreach (var animationEvent in clip.events)
    {
        if (animationEvent.functionName == "AnimationHook")
        {
            return animationEvent.time;
        }
    }

    return clip.length;
}

now I can just copy paste the animation event keyframe and it will "just work"

[rancid frost]

you can use a dictionary for faster look up time

instead of using strings use enums

[pure cliff]

enum for what?

[rancid frost]

"AnimationHook"

[pure cliff]

theres only one

[rancid frost]

oh ok

[pure cliff]

an animation will only ever have 1 hook

and its primarily just for "attacks", "taking damage", and "die" animations

pretty much animations that concern entity A interacting with entity B

where I actually need them to synch up so their 2 animations look right

[rancid frost]

are you creating a choregraphic video?

[devout belfry]

looks like you can register new events tho?

it's iterating over a collection of clip.events

[pure cliff]

uh sort of, turn based combat game where all the entities take their turn simultaneously

[pure cliff]

for sure but just normal events that do normal event things, this will be a specific "special" one I am abusing for this use case, the actual function doesnt do anything

its purely just a way to "tag" a specific frame in a super easy to parse way

but theres just this 1 type of tag atm

[rancid frost]

are you using dots?

[pure cliff]

So at the moment I have examples where like:

Player's turn is them attacking an enemy
Enemy's turn is "die to that attack"

I need to make sure the enemy's death animation, which will play at the same time as the players "swing their sword" animation, occur correctly and look right

[pure cliff]

nope, no idea what that is

[rancid frost]

nvm then, you use the word entities

strange

[spring creek]

Data Oriented Tech Stack

[rigid island]

no because they are not Tile type and don't inherit TileBase

[pure cliff]

uhhh could be akin to that

[rancid frost]

eh

[spring creek]

It's Jobs, ECS, and Burst compiler

[devout belfry]

you could speed it up by using linq queries too, return clip.events.First(x => x.functionName == "AnimationHook").time

[pure cliff]

ah, no, not using those yet

[rancid frost]

linq is slower

looks prettier tho

[rigid island]

linq gets a bad rap

[pure cliff]

shouldnt have a huge impact because ideally I have this run in editor and becomes compiled in as a constant

[rancid frost]

Personally I love it, for simple things, rather write 1 lines than 5

[pure cliff]

cuz every animation is "locked in" at compile time, the times of those events are also "locked in" at compile time and are, for all intents and purposes, now constants

[thorny spindle]

I have a general question

I don't have too much direction at work and I feel like I'm kinda stuck in a rut where I can get things to work with some googling, but my architecture is terrible

Are there any open source Unity projects or smth that I could look at/participate in so that I could see some possibly better thought out code?

[rancid frost]

Make yours

learning from smeone elses code can be a pain

[pure cliff]

Ive got a write up for my approach to my way I organize my project, you can feel free to try it out and if it feels good, its very easy to adapt and use
https://blog.technically.fun/post/unity/building-a-gamestate-with-zenject-in-unity/

[rancid frost]

Surely, there exists a game you fancy and wanna create it

[pure cliff]

I utilize a sort of MVVM approach to the codebase, where I have a game state that has a sort of Pub/Sub model to pushing changes to it, and then subscribing to be notified of changes, and then a service layer that holds 90% of my logic, and then monobehaviors purely have the job of being "glass box" code that each handle purely "what you see", basically they have all the "draw" logic for what is shown to the user.

[misty drum]

im having vector math brain fart moment, what can i put here so the black fill is always aligned inside the LineRendered box(the scale is always right, but position isnt)

[pure cliff]

I really like it cause it keeps all my services decoupled and their only job is to either mutate the game state, and/or subscribe to game state changes and react to them

[thorny spindle]

The site flickering hurts my eyes a little lol

[lean sail]

most open source projects probably arent as readable as you would initially assume. It'd take you very long to actually learn from it. I think one example was unity's chop chop, but that was finished some time ago

[pure cliff]

I really gotta get around to adding a button to disable that ngl

[rancid frost]

I learned this the hard way, downloaded some assets from the store to learn from it. My god was that a pain

[thorny spindle]

Maybe it'll be fun to look at

[rancid frost]

HAHAHAHAHAHAAHAHAHAHA

[thorny spindle]

Or not?

[lean sail]

I too tried looking at another project to see how I should do something, big mistake. It only demotivated me xd

[lean sail]

just calculate the mid point of startPos and endPos if your fill is symmetric.

[pure cliff]

anywho @thorny spindle lemme know if you have any questions about my "PropertyWatcher" architecture, if you decide to try it out, I tried to design that little walkthrough to only take about 30 minutes to try out whilst introducing you to the core concepts of how it all works

I may at some point record a youtube video doing the same tutorial but in video form

[misty drum]

ive been trying, but seems my math keeps getting off, im a lil tired ngl

[thorny spindle]

I really don't want to seem rude, but trying to read the page was giving me a bit of a headache ^^;

[pure cliff]

There's also the gist here for the core code that is needed and examples in my comment at the bottom
https://gist.github.com/SteffenBlake/ace74a893d0b16c30a7eb2a42d6d9230

[lean sail]

google middle of 2 points formula and you'll get what you want most likely

[misty drum]

see, i was too tired to think of that xD ty

[rancid frost]

go sleep

[misty drum]

no 🙂

[rancid frost]

I was once so tired, I looked up,

How to tell if a number is negative

[thorny spindle]

But since I did see dependency injection

Do constructors work with monobehaviours?

[pure cliff]

nah, you gotta do it via a different way with zenject

[misty drum]

worst ive done is "How Vectors", so i know im not that tired yet xD

[pure cliff]

but I personally dont inject anything into my MonoBehaviors

[thorny spindle]

Oh, so that's why you said the asset was needed

Then where do you use it? Just classes that act in the background that your monobehaviours reference?

[pure cliff]

nah thats something else, the .cs file is all the PropertyWatcherBase stuff which you use for building the "Game State" layer, basically it does all the hard work for you of setting up the whole Pub/Sub model

[pure cliff]

Oh tonnes, but my main rule is I always have my MonoBehaviors at the very "bottom" of the tree.

I inject the monobehaviors into my services, but they are the "leafs" of my DI tree

basically, my services "own" the monobehaviors and will do stuff with them, the monobehaviors sit at the very very bottom, nothing gets injected into them

I have a pic here somewhere, one sec

[thorny spindle]

Ah, so the monobehaviours are the last step that gets put in. But won't you have times when you have to initialize monobehaviours with some parameters?

[pure cliff]

indeed, but the service is in charge of that and it keeps track of any entities it has created and it has all the CRUD methods on it

its sort of like MVVM:
GameState's backing model: Model
GameState: ViewModel
Services: Service/Business Layer (not directly mentioned for MVVM but typically used)
MonoBehaviors (aka Entities): Views

I dont include the "model" in the pic cause thats sort of varied by implementation. It could be a database, could be a file, thats up to you

I guess itd sorta look like this

[thorny spindle]

So you have a thing that maintains the top level game states (GameState). Then a layers right below it that manages specific aspects of the game (Service layer). Which then creates/destroys GameObjects (Entity Service)? That have all the general riggings of the Monobehaviour(transform, rigidbody, etc). That notify changes to the Gamestate?

[pure cliff]

Pretty much yup

[thorny spindle]

The Entity service then either talks directly to the Service Layer or the GameState layer as needed?

[pure cliff]

In practice I havent yet had the Entity service actually talk to the GameState, I could but I havent had to. The Entity Service is just another service, I just singled it out cause its the special service that is how all the other services can actually get references to a given entity

[thorny spindle]

But wouldn't scripts in the Service Layer also end up being MonoBehaviours if you end up needing them in the scene with editable fields?

[pure cliff]

Services should be stateless and immutable, they purely are a bunch of "Does a thing" methods on a class

if you wanna have a configuration mechanism, you'd have a seperate class that holds your configuration (which can be a MB if you want it to be editor editable), and then you can inject the config into a service and read values off it

[thorny spindle]

I'd really like to see a project where you've implemented this lol

I feel like that'd be the fastest way to understand

So in a weird way you'd be using the MB class as a holder of values that you then inject into the service when you instantiate

So you could probably just get away with a Scriptable for that or smth

[pure cliff]

yup

personally I prefer to store my configuration in JSON though, but thats just me being a web dev

[thorny spindle]

Ahah

[pure cliff]

largely speaking though I dont really "configure" the services since its a video game, you dont really... configure a game once its compiled and launched

[thorny spindle]

Well I need to work with artist in the company so it'd be nice for them to be able to drag/drop and edit values on the fly the inspector too

[pure cliff]

what would be an example?

[thorny spindle]

I guuueesss you could do it with scriptables and addressables if you wanted to configure after launch

[pure cliff]

I do have 1 special "debug" monobehavior I made explicitly for manually manipulating (and seeing) the GameState at runtime I will note

[thorny spindle]

Just what prefabs to instantiate etc

[pure cliff]

and its setup to not be included in a publish compilation, debug only

[thorny spindle]

Do you have an open project where you've used this kinda configuration?

I'd love to take a gander

[pure cliff]

I dont atm no, sorry D:

[thorny spindle]

D:

[pure cliff]

oh wait

well

I have the example project for that blog post on my github

[thorny spindle]

The lesson was nice though. It's made me think a bit

[pure cliff]

there's a link to it at the bottom of the guide, one sec

[thorny spindle]

Would looking at it give me a better idea of how you're using that system?

[pure cliff]

Sort of, its very bare bones since the services are simple and dont really have dependencies

https://repo.technically.fun/sblake/INotifyPropertyChangedExample

[thorny spindle]

I'll def take a look at it when I get off work then

[pure cliff]

https://repo.technically.fun/sblake/INotifyPropertyChangedExample/src/main/Assets/Scripts/Services/EntityService.cs
This one demos a bare bones basic entity service. Entities are injected in, it handles mutating them and "bubbling up" their events to the game state in a meaningful manner

Note how the ButtonEntity has no contextual understanding of what its "click" event does on its own, the EntityService handles translating that click into actual impact on the game state

And the TextEntity just has a SetText method, it has no concept of what its text is, its just a string and it doesnt care what string is passed into it. It has no conceptual understanding of the game states "counter"

[thorny spindle]

How do you decide what goes in the GameState vs What's in the Service Layer? I'm guessing the Entity service is just whatever the gameobject needs to function

[pure cliff]

GameState is just a whole buncha properties that hold the data

[thorny spindle]

But what data is GameState 'worthy

[pure cliff]

GameState "is a", it doesnt do stuff, it "is" stuff
Services "does a", they are immutable, hold no data themselves, and just "do" things

[thorny spindle]

Ahah

[pure cliff]

Everything more than 1 entity needs to access largely

[thorny spindle]

So the service is literally a bunch of methods that 'do', and all actual numbers are held by the GameState?

[pure cliff]

exactly yup

[thorny spindle]

Seems a little top heavy

[pure cliff]

[pure cliff]

The monobehaviors can be quite large if they have many things to "render"

Largely speaking the monobehaviors domain is the stuff you can "see"

[gloomy stirrup]

wth this website isn't loading even on a good wifi connection ;-;

[pure cliff]

Stuff like a button and text are very simple cuz you typically dont mutate a lot about em (like aside from the text's string itself, mayeb you what, modify if its bold/not, its color maybe? Not a lot you typically modify), but my Player's character entity is about 300+ lines of code long, because theres a LOT of logic for what it visually is doing/looking like

• Translations of its transform
• Direction they are facing
• Animator State
• Collidor events
• Queuing animations (this is the majority of it though)
• Triggers for playing sound effects

[thorny spindle]

Okay. So I have to kinda just make decisions on what data is a 'GameState' and what is 'LocalState' on the fly then

And make the services in the middle methods to go back and forth from these

[pure cliff]

Largely speaking your LocalState stuff is:

1. Not something you need to serialize and save in your game saves
2. Something that only matters to that one entity and others dont need to know about

but yeah you sorta just get the feel for it, usually if you put it on local state and then go "ah dang, I actually need other entities to know this stuff" you then bump it up to the game state

[thorny spindle]

But what if you wanted to save the location and state (HP, attack state, animation state) of every npc in your scene?

Feels like there could be a world where nearly every LocalState is part of the GameState

[pure cliff]

could be yup

Keep in mind that the game state is the like, non abstract version of the data

Like for your HP
Game State: HP is an integer value
Player health bar: HP is its width of the red box in the bar, and the text displayed

So your monobehaviors "local state" are usually more abstract representations of the "real" values

[thorny spindle]

I see. So technically the 'int _health' in this case would the the most base info. Then you would probably have the entity(GameObject) do something else with that data anyway

[pure cliff]

Like for example, my "character state" is an enum in the game state. The monobehavior however is like, what animation is playing

[pure cliff]

precisely yup!

Thats where the services come in, their job is typically to translate that "raw" data into something that the entity can actually work with... if needed

[thorny spindle]

Currently I'm doing something like having a master 'manager' class that then has a bunch of 'lesser manager' classes that take care of stuff

But the difference here is that the lesser managers are pretty tightly coupled to objects in the scene

Like I'd have a UIManager that I just drag/drop UI elements into its inspector

How would I break this type of coupling in this case? It feels like it'd be hard

[pure cliff]

Like for your HP bar, you'd have perhaps

GameState.HP
GameState.MaxHP

And then the service turns it into

float hpPercent = (float)GameState.HP / GameState.MaxHP;
string hpText = $"{GameState.HP}/{GameState.MaxHP}";
HPBarEntity.SetHP(hpPercent, hpText);

[pure cliff]

nothing wrong with your PlayerManager being coupled to the PlayerEntity, that makes sense

its okay if your FooService is coupled to your Foos

[thorny spindle]

But I mean if you want something like your UIManager to ONLY be a bunch of methods

[pure cliff]

for Zenject you'd move those serialized fields over to your Registration monobehavior and register em there

[thorny spindle]

Wouldn't it be better to pull what UI to activate/deactivate not be in its inspector

Since the model seems to say that the UIManager shouldn't be a MonoBehaviour?

[pure cliff]

indeed yeah

[thorny spindle]

Does it just get injected into it?

[pure cliff]

You just move where you "register" your monobehaviors is all

handily, the thingy you use for Zenject is already a monobehavior you can add serialized fields to

[thorny spindle]

But then that would mean that I would just have a ton of scriptables that are referenced by the GameState that then inject these into the lesser managers

[pure cliff]

So Startup is my Zenject registration spot (called a MonoInstaller)

[thorny spindle]

lol assuming I don't use Zenject

[pure cliff]

oh you really do wanna use a DI engine of some sort, manually doing DI by hand is uh... a huge pain

I have like one service stack that is like 6 layers deep

[thorny spindle]

lol the projects at this company is pretty small deals for now

like 1~2 month art projects

[pure cliff]

I would never wanna have to manually do like

new ServiceA(new ServiceB(new ServiceC(new ServiceD(new ServiceE(new ServiceF())))));

[thorny spindle]

So I think it shouldn't be too bad / would be a fun way to be in pain

[pure cliff]

This for example is what my entity service just looks like

[Inject]
public EntityService(GameState gameState, List<EntityBase> prefabs, List<IEntity> entities)
{
    GameState = gameState;
    Prefabs = prefabs.ToDictionary(p => p.GetType(), p => p);

    foreach (var entity in entities)
    {
        Watch(entity);
    }

    Entities = entities.ToDictionary(p => p.Id, p => p);
}

[thorny spindle]

Well how I'd do it is that I'd have scriptables on scriptables on scriptables....

[pure cliff]

Scriptables would be MonoBehaviors, I wouldnt inject a scriptable into a scriptable :p

or whatever their shared parent is

[thorny spindle]

I see what you mean

[pure cliff]

but nah zenject is pretty easy to stand up

[thorny spindle]

My way of doing it would be pretty dumb lol

[pure cliff]

Its like, 4 steps and staples in pretty quick

[thorny spindle]

I was going to set up the scriptable pyramid by hand

then inject it layer by layer lol

[pure cliff]

yeah zenject's whole deal is it handles that for you, highly recommend it

works with IL2CPP too ❤️

[thorny spindle]

oooh

lol

I'll do it by hand first

And then look into it maybe

Or give up in the middle and use it straight away

[pure cliff]

I will note if my blog's post is too difficult to read, you should be able to just Ctrl A + Ctrl C + Ctrl V it into like, google docs to make it more readable

[thorny spindle]

Sorry I've fallen in the hole of depending on assets and then having to tear it apart layer by layer to recreate it due to problems in the past

[pure cliff]

what part actually handles instantiating bullets? all i see is

if ammom is the value you expect it to be then the issue is with firing

        Wheel[] wheels = GetComponentsInChildren<Wheel>();
        wheelInfos = new WheelInfo[wheels.Length];
        for (int i = 0; i < wheelInfos.Length; i++) wheelInfos[i] = new WheelInfo() { wheel = wheels[i].transform };

if can it be shortened with LINQ, how?

[lean sail]

do you really need to use linq for this? its fine as is

[quartz folio]

GetComponentsInChildren<Wheel>().Select(w => new WheelInfo { wheel = w.transform }).ToArray(); ?

[scarlet viper]

thanks thats so much shorter

[pure cliff]

can make a static function too to shorten it more
.Select(WheelInfo.FromWheel) :3

[quartz folio]

now you've got a FromWheel static function too

[pure cliff]

public static WheelInfo FromWheel(Wheel w) { ... }

[pure cliff]

I havent tried it but I wonder if contructors can be implicit cast to Expression<Func<...> for Linq...

[quartz folio]

Doubt it but I don't care to elaborate further on what was a fine answer

[pure cliff]

like can you just do

.Select(new WheelInfo)

if your constructor was just

public WheelInfo(Wheel wheel)

hmm

looks like... no you cant D:

the first thing you should really do is add debugs. You have some debugs so add onto those because right now they arent printing anything useful for you, see what values your ammo types are. I really cant suggest anything else,
1 because i dont want to go through all this code to debug your code in my head and
2 because I cant see what values most of these things are

I'm using a cinemachine POV camera for the vertical mouselook and rotating the gameobject for horizontal, however I'm getting this stuttering / stepping effect when turning. It's especially noticeable when moving and turning at the same time. Any help please?

[ashen yoke]

change update mode to fixed

and/or make sure camera is not parented to the controller

hi guys what is the diffrence between this?

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

public class BuildingSystem : MonoBehaviour
{
    



    public class BuildObject
    {
     //code here
    }
}

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

public class BuildingSystem : MonoBehaviour
{
    



    
}
public class BuildObject
{
     //code here
}

[ashen yoke]

one is valid c# another isnt

sorry its class

there are plenty of differences

nested class has access to all private members of the parent class

nested class accessible through parent class name

thats about it lol

[simple egret]

Consider using the 2nd version if BuildObject is used outside of BuildingSystem.

[thorn summit]

yea is is used outside

[ashen yoke]

yeah , once you have anything serialized as that nested class it will be hard to move it out

[thorn summit]

oh ok thank you guys

[sly gate]

You're a genius...

[sly gate]

Although it has broken my horizontal mouse look, I'll fix that. Thank you 🙂

[ashen yoke]

it happens because it being parented to an object that moves in the fixed update loop prevents it from being interpolated correctly in normal update loop

in most cases you dont want camera attached to an object

I'm having an issue with the cinemachine camera following the yaw of my player. My player is definitely rotating, parented to the player is an emtpy called "Eyes". I've tried setting my virtual camera to try using the player as the body, but it doesn't take the rotation of that either. BTW, I intentionally set the horizontal speed to 0 so that there's no horizontal rotation from the camera.

resolved, i went to package manager and removed a package that had an error

[ashen yoke]

did you open a project in new unity version?

[void sundial]

no, 2020.3.5f1

[ashen yoke]

new relative to the project

[void sundial]

no

[ashen yoke]

so new project and manifest was already broken?

[void sundial]

yes, i just imported the roguelike package and it was automatically broken

https://learn.unity.com/tutorial/unit-mechanics?uv=5.x&projectId=5c514a00edbc2a0020694718 from here

[ashen yoke]

wonder what can prevent pm from pulling deps like that

oh

so i was right

it is a project

[void sundial]

i am sorry, i might have misunderstood your question. It does say i can use 5.x so i assumed it was not new to the project

it is indeed a project from the package manager

[ashen yoke]

anyway, Version 'default' is invalid. Expected a 'SemVer' compatible value this means at some point they changed some syntax/token naming in their dependencies xml/manifest

so package has old or incompatible xml structure so pm fails to resolve deps

[void sundial]

yeah i found that and removed the package that was making the error

and everything works now!

i asked over on #archived-machine-learning but ill post it here if it isnt a problem, it is code related i believe

I'm looking forward to implementing MLAgents to https://learn.unity.com/tutorial/unit-mechanics?uv=5.x&projectId=5c514a00edbc2a0020694718. Do you think it's feesible to do that in 1 week time? I don't need it to be too advanced, just usable!

Hey guys, looking for a name of this type of variable storage with this function (dotween is slightly irrelevant in this case)

s.Insert(0, DOTween.To(() => particleMoveSpeed, x => particleMoveSpeed = x, standardParticleMoveSpeed, transitionSpeed));

I'm lerping the particleMoveSpeed to 'standardParticleMoveSpeed'

if this is just a 'lamba lerp' then thanks for being my rubber duck everybody but if this also has a more specific name I would really appreciate some pointers

[ashen yoke]

yes its lambda, first one is a Func<T> getter, second is Action<T> setter, or whatever delegate types is has declared

the overall term for it is delegate

[halcyon dagger]

Thank you!

thx

Wait just solved the issue, I've spent hours on it but litterily just solved it.

[unique robin]

actually I've still got a few unresolved issues.

So this is the code for my hardcoded 2D character controller so far. I had to stop with some other aspects because the collisions aren't too good. Firstly, running into a wall when on the ground will have an affect of glitching in and out the wall repetitively, and I have no idea how to fix it. Secondly, because you go fastest when in the first half of your jump, you have enough momentum to properly glitch into the wall, despite the fact that my raycasts system is checking 5 tiles to the opposite direction of he wall to find a safe place to teleport too. I have more concern for the second issue as I think maybe making a raycasts to test weather a wall is nearby and then teleporting the distance of Xvelocity minus distance to the wall in the last frame would resolve the first issue.

[main shuttle]

Oof, I just showed you how to post code and then you do it this way that doesn't work on phones and has no colors

[unique robin]

second idea might work really well actually leme give it a try

[main shuttle]

Anyhow, given your text description, usually people don't use the physics methods for physics objects, and translate the physics object into the into the wall and then the physics engine corrects it back again.
This will give you the jittery movement.

[unique robin]

yeah If i do XVelocity minus the distance to the wall in the last frame * -1 if itsd oging to the right then it will correct it in 1 frame i think

[main shuttle]

If you just move with the physics methods you wont have this problem at all.

[unique robin]

Yeah but I don't want to be constantly fighting a rigidbody I want to have control over my character

Also I have programmed parabolic jumps and falling while being able to plug it into desmos and see my jump curve, which I don't think is tooe asy to do with a rigidbody

[unique robin]

Yeah this is easier to code, more peformance efficient and cleaner to run.
