Grid System with ExecuteInEditMode

woven flower Nov 30, 2021, 7:50 PM

#

My game just got stuck in an infinite loop (very hard to reproduce bug that players report, it rarely crashes/freezes). I'm trying to use the Visual Studio for the first time and I can't seem view the source while debugging/stepping (but I can see the Disassembly). I can't close Unity since it's hard to reproduce (I see this extremely rarely)

#

I get the error "The current stack frame was not found in a loaded module. Source cannot be shown for this location." when I try "step".

is your Visual Studio configured properly?

woven flower Nov 30, 2021, 7:50 PM

#

I attached to my game process (Unity.exe - Game is the title).

sly grove Nov 30, 2021, 7:50 PM

#

Do you get IntelliSense?

woven flower Nov 30, 2021, 7:51 PM

#

And when I unpause, I hear my game's music but it's frozen

#

What's IntelliSense?

sly grove Nov 30, 2021, 7:51 PM

#

Like the auto suggestions as you type code

woven flower Nov 30, 2021, 7:51 PM

#

Yeah I got those

#

It's attached I think (Unity.exe - Game) because if I unpause I hear the music, if I pause it stops the music

#

but the Unity editor is frozen, so it's inside an infinite loop of some sort I believe

sly grove Nov 30, 2021, 7:52 PM

Something's off about your debugger

woven flower Nov 30, 2021, 7:52 PM

#

#

I'll mess around with the settings

sly grove Nov 30, 2021, 7:52 PM

#

you should be able to just set breakpoints in your source code, and when you hit play it should attach to unity automatically, you shouldn't have to select a process

#

unless you're debugging a build

woven flower Nov 30, 2021, 7:52 PM

#

sly grove Nov 30, 2021, 7:52 PM

#

I.e. it should look this way

woven flower Nov 30, 2021, 7:52 PM

#

I'm debugging my Unity editor in play mode

sly grove Nov 30, 2021, 7:52 PM

#

then you shouldn't have to select a process

woven flower Nov 30, 2021, 7:52 PM

#

sly grove Nov 30, 2021, 7:53 PM

#

are you using breakpoints?

#

Or just pressing pause

woven flower Nov 30, 2021, 7:53 PM

#

nope, I just looked into debugging the first time my game froze on me

sly grove Nov 30, 2021, 7:53 PM

#

you need to set breakpoints in the code

woven flower Nov 30, 2021, 7:53 PM

#

it's really hard to reproduce

#

oh

#

It happens extremely rarely, like once every few days of development hmm

sly grove Nov 30, 2021, 7:54 PM

#

Click in the margins and make a breakpoint

#

looks like this dot

woven flower Nov 30, 2021, 7:54 PM

#

so without breakpoints, I won't be able to view the source code?

sly grove Nov 30, 2021, 7:54 PM

#

then the debugger will stop there when the game reaches that point in the code

woven flower Nov 30, 2021, 7:54 PM

#

Mmm, I can take a look at that but I don't know where it freezes, could be anywhere

#

so not sure where I can put this breakpoint if I don't know where the loop is

sly grove Nov 30, 2021, 7:54 PM

#

How many loops do you have 😛

#

what are you doing in your game when the freeze happens?

woven flower Nov 30, 2021, 7:55 PM

#

Well, it could be infinite recursion or anything, no idea 😄 I'll set some random breakpoints in

#

and hit play

sly grove Nov 30, 2021, 7:55 PM

#

no

#

infinite recursion will not freeze the game

#

you will get a stack overflow exception

woven flower Nov 30, 2021, 7:55 PM

#

oh yeah true

sly grove Nov 30, 2021, 7:56 PM

#

it can only be a loop

#

while loop or for loop

woven flower Nov 30, 2021, 7:56 PM

#

I'll search "while" and set a breakpoint for each while

#

Possibly something wrong with my project, I'll do a quick search

sly grove Nov 30, 2021, 8:07 PM

#

woven flower Possibly something wrong with my project, I'll do a quick search

something seems weird about your Unity <-> Visual Studio connection

woven flower Nov 30, 2021, 8:09 PM

#

probably yeah. I tried attaching to unity instead of via process, but it's a bit odd. I think I'll mess around with a debugger tutorial or two to make sure I'm ready the next time I come across the hard to reproduce bug

#

#

Thanks anyways for the help, I'll prepare myself. The debugger looks really nice on YT, should've learned it earlier

woven flower Nov 30, 2021, 8:29 PM

#

P.S. I managed to find the cause of the infinite loop by forcing an exception to be thrown by changing a value in the register (credit: https://blog.unity.com/community/breakout-how-to-stop-an-infinite-loop-in-a-unity-c-script). Now to learn the Unity debugger properly so I can debug things properly in future

I have a project compiling to a 4.7.2 framework DLL that contains all my domain models and utilities. I was considering putting my services here since I now have another project (Blazor admin tools) that needs these services (ie - Cosmos DB). However, I have a Unity project that doesn't need those services (and in fact specifically might have issues with it).

Should I make a second shared project for these services?

Current structure:

1) Shared (models are here currently)

+ -- 3) Admin tools (new project that needs services & models)
+ -- 4) Unity client(s) (existing project that needs models but not services)

quick q about rpcs in unity netcode

for something like stats, only the player who has the stats will ever need to know what they are - if the stat variables are made into network variables on the player object, I’m assuming they’ll be updated for every client, right?

if so, are rpcs also sent to every client, or just the client version of that script?

RPCs can usually be targeted to a specific client when supplied that client's ID in the method signature, Network-/SyncVariables are usually not targeted as their main purpose is to sync state rather more persistently (i.e. data that would be relevant for clients that join later). Think of RPCs as transient and vars as persistent and their respective features being motivated by this classification.

You can however put certain sync vars on a network object that is only visible to a subset of all clients. Then those sync vars will only be updated on clients when the object is visible. This behaviour may depend on the implementation of visibility/syncVars in your chosen networking library/framework.

Vector3 pos = transform.position;
float newX = Mathf.RoundToInt(pos.x/gridsize)*2; 
float newZ = Mathf.RoundToInt(pos.z/gridsize)*2;
float newY = pos.y;
//float newY = Mathf.RoundToInt(pos.y/gridsize); //if you also wanted to align vertically.
transform.position = new Vector3(newX,newY,newZ);

Does anyone know why public delegates and events might not get recognised when using DLL in Unity, but works just fine in regular .net project.

fresh salmon Dec 1, 2021, 1:43 PM

#

I'm not sure what I should be looking at here, the delegates are declared in the top window, but I don't see the relation to it in the bottom window

#

Also you have invalid syntax in the bottom one, the constructor must declare a body

silk hare Dec 1, 2021, 1:43 PM

#

The bottom is the metadata unity has generated for the dll.

fresh salmon Dec 1, 2021, 1:43 PM

#

Ah, alright

silk hare Dec 1, 2021, 1:43 PM

#

As indicated by the [from metadata] tag.

#

Do you know why this might not get included?

fresh salmon Dec 1, 2021, 1:45 PM

#

Are they only absent in the metadata, or do you get compiler errors when trying to reference them?

silk hare Dec 1, 2021, 1:46 PM

#

Yeah, the compiler generates errors based on the generated metadata IIRC.

fresh salmon Dec 1, 2021, 1:53 PM

#

I can't find any similar issues on the internet, and delegates get decompiled well on my end (using https://sharplab.io)

You could use a real decompiler, or enable the one in Visual Studio (settings, navigate to decompiled sources) to see if they got generated

Yeah, that's what i'm messing around with right now as well.

#

It doesn't seem to be represented in the dll at all?

#

But I am able to use it on my other test project without errors.

#

It must have something to do with compile settings since my other non-unity test project is using visual studios reference system; this is the only thing I can think of.

#

Ahhh

#

It was optimized away...

fresh salmon Dec 1, 2021, 2:17 PM

#

That's weird, the delegates and events are public and contained in a class that is public. If they were internal to the assembly and nothing used them it would have made sense to optimize them

hello, i have a little problem with unity event
i have an event (event1) i want to copy the event of this event1 in an other event2 from the inspector, so i've made a button
The problem is that, when i copy the event1 to the event2 (juste like event2 = event1), it copy the data, but now event 1 is link to event2, so if i modify event2, it modify event1 too

#

does anyone know how to solve this ?

final hare Dec 1, 2021, 4:34 PM

#

mental rapids does anyone know how to solve this ?

i didn't understand it clearly but
try using a temporary variable so the main ones can't connect directly

mental rapids Dec 1, 2021, 4:35 PM

#

already tried temp vars, it didn't work
to my mind, it copy the memory adress of the unity event, not the unity event

misty glade Dec 1, 2021, 4:36 PM

#

you are correct, you are just setting t he "memory address" of the variable to the event (it's called a pointer, but we don't really use that term in c#)

#

If you want to "copy" the event then you need to create a clone of it

#

(which you usually don't do for things like events)

#

what are you trying to accomplish?

mental rapids Dec 1, 2021, 4:39 PM

#

i have make my own "timeline signals", because the unity signals was not really good for my use
So when i copy paste one of my marker (i call it like that), it copy past the data too, and the data is unity event

#

so i need to create a clone of the copied marker"s unity event

sly grove Dec 1, 2021, 4:48 PM

#

mental rapids so i need to create a clone of the copied marker"s unity event

I don't think there's any nice way of copying UnityEvents without using reflection

mental rapids Dec 1, 2021, 4:49 PM

#

yeah, after some research, every topics was speaking about reflection, don't really know what it is but i think i'll have to learn this

sly grove Dec 1, 2021, 4:49 PM

#

UnityEvent has two lists of callbacks - one is the AddListener method that uses a non-persistent C# deelegate, and the other is the persistent callbacks list. You can only add persistent callbacks from the GUI

#

You can read persistent callbacks data from the UnityEvent, but not add one

mental rapids Dec 1, 2021, 4:50 PM

#

okay, thats a good infos to know

misty glade Dec 1, 2021, 8:36 PM

2 hours later... Reminder: don't ever move script assets around outside of Unity (and delete the .meta files) because Unity won't be able to tie those scripts to prefabs/objects and you'll have to manually readd them all.

tough tulip Dec 1, 2021, 9:53 PM

in that case, try to subscribe those delegates in the dll itself once to an empty function, do a compilation once(with optimizations) and then check if that works. It should most likely

Is it reasonable that there are errors in build that do not show up in editor
for following conditions:

I'm running exact same C# code
I'm running on a well supported platform Windows/Linux
I'm not using IL2CPP (added)

austere jewel Dec 2, 2021, 4:59 AM

#

No. Runtime errors can occur because of stripped code, which could be because of IL2CPP or various other reasons. I'm sure there's more.

hollow wing Dec 2, 2021, 5:00 AM

#

well good you mentioned IL2CPP, if I add that to the list of restrictions: see edit ^

#

what "other various reasons" are there?

#

I would like to get a build to a point where I can say "the code is supposed to behave almost certainly like the code in the editor"

austere jewel Dec 2, 2021, 5:02 AM

#

It would be easiest if you just describe what error you're having and the scenario it occurs in instead of covering all possible bases.

hollow wing Dec 2, 2021, 5:02 AM

#

who says I'm having an error

#

If you make a build send it to someone they test it and get an error

#

wouldn't it be great if you could send another build that is "supposed to work" as a methodology for narrowing down?

austere jewel Dec 2, 2021, 5:05 AM

#

You would know what the error is so you would go from there

hollow wing Dec 2, 2021, 5:11 AM

#

even if you have a clean stack trace available

#

that does not mean you know the reason of the error

sly grove Dec 2, 2021, 5:12 AM

#

hollow wing what "other various reasons" are there?

There are many differences between the many different target platforms that Unity supports

hollow wing Dec 2, 2021, 5:12 AM

#

the goal for me is narrowing it down

sly grove Dec 2, 2021, 5:12 AM

#

That is one source of errors

hollow wing Dec 2, 2021, 5:12 AM

#

exactly

austere jewel Dec 2, 2021, 5:12 AM

#

Sure, but not knowing anything about it at all doesn't help narrow anything down, asking for an exhaustive list is unreasonable. Maybe someone else can be bothered, but I certainly can't.

hollow wing Dec 2, 2021, 5:12 AM

#

that's why I'm figuring whether there is one that is closest to "ground truth"

sly grove Dec 2, 2021, 5:12 AM

#

Another source of error is different framerates, resolutions, and device capabilities of the running hardware as well

hollow wing Dec 2, 2021, 5:15 AM

not sure if anyone could give an exhaustive list, but if the mentioned would include 99% of cases that would already be a win for me personally

You will never be able to make 99% visible to debug against. By the time you include the current state, which will give you months to years of work, there is new stuff coming up which will again add up. Thats some romantic belief, that we can avoid any circumstance in development, but not reality 😉 Find your target audience, find the most used devices/platforms or what not, and go from there.

Maybe with a switch expression if you can adapt the code

I'm also wondering why you have to use constants, since it seems to say that was only in version 6 and earlier.

fresh salmon Dec 2, 2021, 12:01 PM

#

I think the values must be constant because of the limitations of the IL code, where it branches (jumps) if some condition is true.
But it was fixed in later versions maybe? I don't remember

final kindle Dec 2, 2021, 12:02 PM

#

#

It puts in under the 6 and earlier bullet points, so I have to assume.

fresh salmon Dec 2, 2021, 12:03 PM

#

Oh yep, the issue being that Unity doesn't use the same runtime as dotnet, and some features are unsupported

#

Non-constant values might be one of them

austere jewel Dec 2, 2021, 12:04 PM

#

Relational patterns were introduced in 9.0 iirc

2022 might have access to that syntax, but I'd have to give it a go. I also thought it only worked in switch expressions

Typically a physics engine will do a broad phase check to gets lists of bodies that are potentially close enough to collide, then do different kinds of specific collision checks depending on how those bodies are set up. But I'd say it'd be relatively rare for a 2D platformer to write its own physics simulation these days, since Box2D is free and very time-tested.

(To be clear, Unity's 2D physics uses Box2D internally.)

Yeah, as far as I know 2D physics will do it in the "Internal Physics Update" step, same as 3D physics: https://docs.unity3d.com/Manual/ExecutionOrder.html

dry rover Dec 2, 2021, 12:40 PM

so then i should move using physics.velocity, and try to get the contact points to move back the actors to where they collided

Why is this sounding like you are using physics but still want to create your own physics

dry rover Dec 2, 2021, 12:41 PM

im not using physics but tjm and anikki are suggesting that i should do it

if you use a kinematic character controller you probe for collisions manually and resolve them via the collision info you get from the collision tests you do/receive... they are basically resolved in that data but not applied yet.

#

if you have two kinematic actors, you have to enable kinematic collisions between them in physics settings and deal with the collision separation manually... or let the physics engine handle that temporarily if you want simulated physics for that response

So lets say like in super mario, you squash the goomba when jumping on it

compact ingot Dec 2, 2021, 12:45 PM

#

goomba and mario, at a basic level, are just movable platforms to each other, with some extra features

dry rover Dec 2, 2021, 12:45 PM

#

during on collisionEnter you would get the contact points, see if mario was on top, then move mario back to where they made contact the first time and then kill the gooba and make mario jump?

compact ingot Dec 2, 2021, 12:46 PM

yes

Or just do a rigidbody.AddForce to it so it jumps up after collision tag == "Goomba" for example. lots of ways, depending on your game mechanics

orchid marsh Dec 2, 2021, 12:47 PM

#

I'd simply put a collider at the top of the goomba to cause it's destruction and players bounce.

compact ingot Dec 2, 2021, 12:47 PM

hollow knight does its movement largely with physics and some tweaking of the forces on certain events to get the right 'feel', better jump curves etc.

Well you either use collision from physics to prevent that or when on collision, get their directions and prevent them from moving in that direction, but I would just go with physics. still depends on your usecase

it depends on how you want your game to feel really

They ought not be going through each other unless they're traversing as great speeds.

compact ingot Dec 2, 2021, 12:51 PM

dry rover even if they are not traversing they end the frame at different points each time

that may be because physics aren't deterministic

orchid marsh Dec 2, 2021, 12:51 PM

#

Ah, Kinematic (jumped in without the full disclosure - reading past posts).

compact ingot Dec 2, 2021, 12:52 PM

#

it boils down to this: kinematic == total control, simulated physics == easier to get things moving.

dry rover Dec 2, 2021, 12:52 PM

#

yes, it will in any case be kinematic

#

the question is> use physics and resolve what happens during OnCollisionEnter

#

or

#

raycast and resolve as we are moving

#

in both cases you can use physics of course, but i just mean "OnCollisionEnter"

compact ingot Dec 2, 2021, 12:54 PM

#

well, onCollision gives you info what has happened, and raycasts give you information what will probably happen relative to input and your knowledge of your game-design... you design your system from there

midnight violet Dec 2, 2021, 12:55 PM

#

But oncollision is not a thing with kinematic bodies, right

compact ingot Dec 2, 2021, 12:55 PM

#

ofc it is

dry rover Dec 2, 2021, 12:55 PM

#

yes

compact ingot Dec 2, 2021, 12:55 PM

#

you can make kinematics receive collision information... just have to enable it in settings

midnight violet Dec 2, 2021, 12:55 PM

#

"Collision events are only sent if one of the colliders also has a non-kinematic rigidbody attached" is wrong then? 😄

dry rover Dec 2, 2021, 12:55 PM

#

you have to set in settings

midnight violet Dec 2, 2021, 12:56 PM

#

Is it the static pairs setting?

dry rover Dec 2, 2021, 12:56 PM

#

yes for 3d

compact ingot Dec 2, 2021, 12:56 PM

#

dry rover Dec 2, 2021, 12:56 PM

#

i don-t know if it-s enough with "Use full kinematic contacts" for 2d

#

on the rigidbody2d component

compact ingot Dec 2, 2021, 12:57 PM

#

well, raycasts are more useful anyway

dry rover Dec 2, 2021, 12:57 PM

#

yeah, i already do that, so it would make sense to use that method

#

i do it for level geometry

#

the problem with that is that the actor that gets processed first, gets to move more than the other

#

🙂

compact ingot Dec 2, 2021, 12:59 PM

#

dry rover the problem with that is that the actor that gets processed first, gets to move ...

well, you can work around that... you don't have to process the data right when it arrives, you can collect it and resolve 'later' when all info is available

#

the physics engine internally resolves collisions iteratively... there is really no other way since collisions resolution can't be calculated by a closed formula in the generic case

#

but you can create a special case for your game where that might be possible, as you can control all the constraints

dry rover Dec 2, 2021, 1:02 PM

#

ok, i'm gonna try both approaches, and see which one feels better and is easier to implement

I'm running into a search-wall.

I'm generating prefabs from FBX files using an editor script.

If the FBX has been updated, I want the editor script to check if there's a previous prefab for that FBX, and copy its components onto the newly generated prefab (to handle changes made to the prefab since it was generated from the FBX). I have this working, but with one problem: internal references become null through the copy.

Simplified version:
Create a gameobject with a child gameobject. Make two separate prefabs of that object. On one of the prefabs, add a script to the parent that references the child. Copy that component from the prefab and paste as new component to the other prefab. The child reference will be null.

I want to use an editor script to perform this copy, and preserve this child reference, by using the gameobject names figure out what internal prefab references should go to what thing. When I convert the component on the first prefab to json, its references say instanceID:0.

#

Any ideas?

#

I'm assuming instanceID hasn't been set because the objects aren't in a scene. They're just in a prefab. But there's got to be some way to check the internal references in the prefab and reproduce them in another.

Suppose a shooter game. We have two types of states, states related to logic and states related to animations. To make a decision or doing something based on (preconditions), sometimes we need to know the states in logic and sometimes in animations.
An example:
A player can be equipped or not (armed/unarmed). When the player is equipped, the logic related state changes instantly but the animation state changes to equipped when the equipping animation ends.
Now, imagine a situation that the player would like to fire. The precondition of shooting is equipping. Here, we should consider equipping animation state (After equipping finishes completely, now the player can fire)

They can be non synchronized. Do you prefer to synchronize them?
How do you distinguish between them?
Scripts which are views, should interact with animation states not logic related states?

Hello I am working on procedurally generated terrain using a marching cubes algorithm, and while my alhorithm seems to work when I go to actually create the mesh unity seems to refuse to draw more than 4 triangles am I missing something or doing something wrong I've tried searching all day and could not find any information
here is the code where I assign all the vertices and tris (I also create sphere primitives at the vertex's positions for testing)

void UpdateMesh()
    {
        mesh.Clear();
        mesh.vertices = vertices.ToArray();
        mesh.triangles = triangles;
        foreach (Vector3 v in mesh.vertices)
        {
            GameObject sphere = GameObject.CreatePrimitive(PrimitiveType.Sphere);
            sphere.transform.position = new Vector3(v.x, v.y, v.z);
            sphere.transform.localScale = new Vector3(0.1F, 0.1F, 0.1F);
        }
        mesh.RecalculateNormals();
    }

#

here's what it looks like in game

#

I've tried many different arangements and no matter what it will not draw more than 4 triangles

Make your area a lot smaller

Like 2 grid slots

timber flame Suppose a shooter game. We have two types of states, states related to logic and...

This seems like more of a question of game design than code? I think it depends on the type of game. Personally I think most games feel better to play when they use the logic state to determine what the player can do without forcing them to wait for the animation to catch up, but sometimes slower-paced games will want the opposite. Obviously in the first case that means your animation state needs to be able to cope with receiving logic changes faster than it can handle them.

Hello. To get a list of all objects of a certain type, active and inactive from the current scene the Docs says you can use Resources.FindObjectsOfTypeAll https://docs.unity3d.com/ScriptReference/Resources.FindObjectsOfTypeAll.html
They are filtering objects in scene like this:

  if (EditorUtility.IsPersistent(go.transform.root.gameObject) && !(go.hideFlags == HideFlags.NotEditable || go.hideFlags == HideFlags.HideAndDontSave))
                objectsInScene.Add(go);

The problem is that the EditorUntility is in the UnityEditor namescpace and the script wont compile for a final build unless moved to the Editor folder which would remove it entirely from the build

So how can I go around this?
Thanks

#

inland prairie Hello. To get a list of all objects of a certain type, active and inactive from ...

what type of objects are you trying to find?

inland prairie Dec 2, 2021, 10:57 PM

#

a specific type

dry rover Dec 2, 2021, 10:57 PM

#

like all Gameobjects or all "MyEnemy"

inland prairie Dec 2, 2021, 10:57 PM

#

lets say MyClass

#

yeah

#

the second

dry rover Dec 2, 2021, 10:58 PM

#

then myClass could put itself in a static list of MyClasses when is spawns and then eveyrone can acces the list

inland prairie Dec 2, 2021, 10:58 PM

#

Resources.FindObjectsOfTypeAll(typeof(MyEnemy))

#

nope

dry rover Dec 2, 2021, 10:59 PM

#

as a way around i mean

inland prairie Dec 2, 2021, 10:59 PM

#

because it has to be active and inactive

dry rover Dec 2, 2021, 11:00 PM

#

is it spawned?

inland prairie Dec 2, 2021, 11:01 PM

#

is loaded but not active in the scene

dry rover Dec 2, 2021, 11:01 PM

#

by something or just exists in the level?

inland prairie Dec 2, 2021, 11:01 PM

#

thus Awake nor Start wont get called

dry rover Dec 2, 2021, 11:01 PM

#

how is it loaded?

inland prairie Dec 2, 2021, 11:02 PM

#

Player input that will create a specific type of object based on Player's hardware

#

and it loads in a thread

#

so I cannot immediatelly know if it loaded

dry rover Dec 2, 2021, 11:07 PM

#

ok, i'm not sure i understand sorry. I would guess that in this thread at the point where the class is loaded you would have a reference to this class and thus could put it in a list. But i probably don't understand how it is working

inland prairie Dec 2, 2021, 11:07 PM

#

it is a closed API in a dll

#

All I can do is call the API and it will generate the objects in scene

dry rover Dec 2, 2021, 11:07 PM

#

i see

inland prairie Dec 2, 2021, 11:07 PM

#

I do get a callback which is where I am hooking the logic to find all of them

#

but some of them are inactive, and I need to add them to the list too

dry rover Dec 2, 2021, 11:09 PM

#

and you get the callback for all of them or just the active ones?

inland prairie Dec 2, 2021, 11:10 PM

#

I get a callback when it finished creating all of them, but I dont get any params in the callback

#

Hence I need to find them myself

dry rover Dec 2, 2021, 11:12 PM

#

but why cant u use this? https://docs.unity3d.com/ScriptReference/Object.FindObjectsOfType.html

formal lichen Dec 2, 2021, 11:13 PM

use FindObjectsOfType with the includeInactive bool to true

inland prairie Dec 2, 2021, 11:13 PM

what

inland prairie Dec 2, 2021, 11:16 PM

but the flag is only when parents are inactive but the object itself is active

#

if the object itself is inactive it wont be returned

tough tulip Dec 2, 2021, 11:16 PM

FindObjectsOfType takes a boolean parameter. Passing true will return inactive objects aswell

                continue;

            if (go.gameObject.scene.isLoaded) continue;

To filter them

but still get returned

u are using Object.FindObjectsOfTtype(true)

#

?

inland prairie Dec 2, 2021, 11:21 PM

#

yep

tough tulip Dec 2, 2021, 11:22 PM

#

inland prairie but I dont want the prefabs

not possible.
Show us the code and also tell us how you're so sure it returns a prefab

tough tulip Dec 2, 2021, 11:23 PM

#

inland prairie indeed is returning all the prefabs

I mean for this

formal lichen Dec 2, 2021, 11:23 PM

#

~~don't use Object,~~ nvm it's just extra specificity, still returns Object[]

inland prairie Dec 2, 2021, 11:23 PM

#

tough tulip Dec 2, 2021, 11:24 PM

#

and how are you sure that a prefab is being returned?

#

I hope by Prefab, you mean a reference to a prefab in script, and not a prefab which is already in scene

inland prairie Dec 2, 2021, 11:24 PM

#

Then after this runs I check the list on the inspector, I click in one of them and it points to the project folder and selects the prefab

#

The list is popullated with almost triple objects that are actually in the scene

cosmic basalt Dec 2, 2021, 11:29 PM

#

sorry im jumping into the convo late, what do you mean you want the prefabs and not the objects?

small badge Dec 2, 2021, 11:30 PM

#

If true that would be an editor bug, as the docs specifically say that Object.FindObjectsOfType() will not return assets. You're probably not going to find an alternate function that doesn't return assets because that is the function that doesn't return assets.

inland prairie Dec 2, 2021, 11:30 PM

#

cosmic basalt sorry im jumping into the convo late, what do you mean you want the prefabs and ...

Its backwards, I only want to find objects of type in the scene but not the references to the prefabs in the project files

dry rover Dec 2, 2021, 11:31 PM

#

inland prairie

i tried your code, still doesnt return prefabs

#

😦

inland prairie Dec 2, 2021, 11:31 PM

#

I know is a prefab because when you right click on it in the inspector list

#

there is an option to copy the path if it is a prefab

#

when you copy the path it copies the actual path to the prefab

#

versus if you right click on the item when it is not a prefab, the copy path option will be grayed out

dry rover Dec 2, 2021, 11:32 PM

#

yeah, i believe you, i-m trying to replicate it

#

mine only point to the scene objects

tough tulip Dec 2, 2021, 11:32 PM

#

what editor version are you at?

cosmic basalt Dec 2, 2021, 11:32 PM

#

yeah that code looks right to me

inland prairie Dec 2, 2021, 11:33 PM

#

2020.3.19

tough tulip Dec 2, 2021, 11:35 PM

#

pretty much unlikely to be an editor bug.
one way to confirm it is by checking parents name recursively until null

inland prairie Dec 2, 2021, 11:35 PM

#

let me write some code for it

dry rover Dec 2, 2021, 11:36 PM

#

but anyway

cosmic basalt Dec 2, 2021, 11:36 PM

#

im not sure what you mean about copy path

#

but if you right click on it, it has the prefab context menu as well?

dry rover Dec 2, 2021, 11:36 PM

#

if u use: gameobject.scene.isLoaded it should tell you if it is a prefab, so that is strange

cosmic basalt Dec 2, 2021, 11:37 PM

#

yeah and that function explicitly says it will not return that stuff

tough tulip Dec 2, 2021, 11:41 PM

#

another way to confirm if it's an asset is by calling Destroy function. unity throws an error.

you can also try to reparent the prefab from the reference. unity throws an error if it's a prefab.

cosmic basalt Dec 2, 2021, 11:42 PM

#

have you tried asking it nicely

small badge Dec 2, 2021, 11:42 PM

#

Or go right to the source, PrefabUtility.IsPartOfPrefabAsset().

inland prairie Dec 2, 2021, 11:44 PM

#

Alright, good news is that it works and it was a false alarms, Object.FindObjectsOfType(true) only returns references to objects in scene as expected

#

The bad news (not really bad) is that I wasted your time due to a VS issue, I hate VS that sometimes it wont sync immediately the code with Unity

I see, so the includeInactive was introduced in Unity 2019.2

#

That is why when I tried Object.FindObjectsOfType back then it wasn't working for me

#

and now that I am revisiting this code I can use the new includeInactive flag, that is great

I'm trying to understand 2D Collisions. Namely i have 2 BoxColliders moving Through each other and i want to find what position they are at when colliding

#

if i call OnCollisionEnter it only returns the position at the end of the frame (when they both have passed each other)

compact ingot Dec 3, 2021, 12:09 AM

#

you don't call OnCollisionEnter, and its the position after the last physics update, physics are frame independent

dry rover Dec 3, 2021, 12:09 AM

#

if i use contacts i have the contacts but i don't know how to get the position of the objects

compact ingot Dec 3, 2021, 12:11 AM

#

you get the position via Collision2D.transform.position

dry rover Dec 3, 2021, 12:11 AM

#

how would you go and find the position? i tried raycasting but it has the same problem

dry rover Dec 3, 2021, 12:12 AM

#

compact ingot you get the position via `Collision2D.transform.position`

where do i get the collision2D

#

?

compact ingot Dec 3, 2021, 12:12 AM

#

MonoBehaviour.OnCollisionEnter2D(Collision2D) https://docs.unity3d.com/ScriptReference/MonoBehaviour.OnCollisionEnter2D.html

#

you get it automatically when the collision event method is invoked

dry rover Dec 3, 2021, 12:13 AM

#

but the transform position is after the objects have moved

#

it returns the end position of each object not the position when they hit each other

#

or rather it returns the position at the end of the frame

compact ingot Dec 3, 2021, 12:14 AM

#

if you want to disable the collision resolver, then make the objects kinematic

dry rover Dec 3, 2021, 12:14 AM

#

but they hit before reaching the position and i don+t know where

#

yes they are kinematic

compact ingot Dec 3, 2021, 12:14 AM

#

enable kinematic pairs, and resolve the positions manually

dry rover Dec 3, 2021, 12:14 AM

#

i do all that but i don´t know where the collision happens

#

i know what frame and where the objects are at the end of the frame

compact ingot Dec 3, 2021, 12:15 AM

#

it happens between the last position and the current position

dry rover Dec 3, 2021, 12:15 AM

#

yes,

#

but where? 🙂

compact ingot Dec 3, 2021, 12:15 AM

#

there is no more accurate position than that

#

you have to "guess" or calculate one based on their relative velocities

dry rover Dec 3, 2021, 12:15 AM

#

well collision.getcontacs hase accurate positions

#

ok

compact ingot Dec 3, 2021, 12:15 AM

#

those are contacts, and they are not really accurate

#

accurate enough maybe

#

the collision contains ContactPoint2D.separation, that together with the contact normal, and all other contacts also gives you a clue how the collision can/should be resolved and where it happened.

dry rover Dec 3, 2021, 12:21 AM

#

i guess, i hoped there would be a more straightforward way, thanks

compact ingot Dec 3, 2021, 1:02 AM

maybe when you re-think your system design you find a solution that achieves the same goal by more conventional means which are supported by the unity API out of the box.

You could cast your collider between the frames to get contact points.

The thing is i am just trying to make a simple super mario clone where mario jumps on the goomba to kill it. I understand that it will work with OnCollisionEnter, but if the goomba is moving up and mario is moving down the collision will be accurate enough but not really accurate. I thought there was some common practice to solving this kind of situation since it is a fairly common mechanic.

Then you've got to handle it on your own.🤷‍♂️

dry rover Dec 3, 2021, 12:12 PM

yes 🙂 i just thought there was a "100 years old method" to do this 🙂

#

i don't want to reinvent the wheel

untold moth Dec 3, 2021, 12:13 PM

#

The recommended workflow is to let physics handle it. That's the 100 years old method. Otherwise you handle it on your own which is also a 100 years old method.

#

usually using casts of different type.

Is there any way to combine a [Tooltip("")] with XML automatically? I'm using doxygen to auto generate documentation but it does not pick up the Tooltip attribute, so any time I want information displayed both in the editor and in the generated docs, I have to write a <summary> and a tooltip.
The question has been raised before but haven't found any solutions out there, I suspect there might be some way to use a custom attribute or preprocessor but don't know where to start with those

This would be possible with IL post processing/IL weaving, which Unity unofficially supports. Burst and the ECS package use IL post processing to modify the compiled assemblies and it's possible to make your own IL post processor, but it's not documented and could suddenly stop working.
Here's some information about it:

ILWeaving won't let you generate <summary>, it'll let you generate the attribute though but finding the docs might be non trivial

not sure if this is "advanced" enough but... how do people typically implement textual player notifications? through direct calls (e.g., `notificationmanager.notifyplayer("message")), through callbacks (e.g., notification manager will add its own notification methods to various game entity callbacks), or through polling (e.g., notificati/on manager holds references to various game objects, periodically polling them to check values, and notifying when some event occurs)? or through something else?

Does anyone here have experience using a UPM package sourced from a git repository, with a particular revision specified? I've tried following the documentation for it in the manual (for version 2020.3), but UPM keeps saying it was unable to clone to repo because the revision (a tag in this case) was not found. The tag is definitely there, and when I reviewed the set of git commands that UPM is using to acquire the package source, it seems like the problem is that it's creating a shallow git repo, at least that's what I was able to confirm with someone in the official Git IRC channel.
Has anyone else had this setup work for them, and if so what version of Unity and Git were you using? Thanks!

Meshes are made up of vertices and triangles. The Mesh object contains data about all of the triangles, and you can infer their direction from the order of the vertices in each triangle. You can get the normal of a triangle from new Plane(pointA, pointB, pointC).normal

What PB said. Find the normal vector (https://mathinsight.org/forming_planes if you want to do it by hand, or .normal above) and surface area of all of the triangles (https://math.stackexchange.com/questions/128991/how-to-calculate-the-area-of-a-3d-triangle), multiply each normal times the SA of the triangle, add all of them up and that should be your total drag on the system. I'm no scientician, though, so.. you know, check your work with someone smert. 🧠

Oh cool. I thought that there may have been a way to count back up to 5, to reset the counter instead of just a 10-5-0 check

gentle topaz Dec 3, 2021, 10:31 PM

#

technically, setting it directly to 10 will cause small inaccuracies to add up over time. Doing hoverCount += 10 instead would get rid of the small inaccuracies.

#

assuming this is constantly looping every 10 seconds

pastel moth Dec 3, 2021, 10:33 PM

#

gentle topaz assuming this is constantly looping every 10 seconds

Yeah it depends on the length of the path and if it's killed or not. Are you talking about the 100th's of seconds etc..? I have a few counters like this so assume I should change them all?

gentle topaz Dec 3, 2021, 10:36 PM

#

well, thats for you to decide, but the issue is simply that: let's say you had a lag spike when the timer was at ~.01 (basically zero) seconds left. As soon as the game recovers from the small lag spike, deltaTime will be larger than usual, and you will subtract much more from the timer at the end of the frame. Lets just say that timer is now at -2 seconds. Then, when the next frame starts, you will basically just ignore that lost time because you are setting it directly to 10, whereas adding would put the timer at 8 seconds which is more accurate since you spent 2 seconds with the game lag spiking

#

I used two seconds as an exaggerated example

pastel moth Dec 3, 2021, 10:38 PM

Awesome explanation, that makes sense and I will update it everywhere since it is actually appropriate - it will likely fix issues with my guns I haven't noticed due to the minute timings

Even if you could, it wouldn't do anything; you're getting a copy of the object's position and changing the copy's Y value; that won't move the object. If you want to change the object's position you need to set a new Vector to transform.position.

cosmic basalt Dec 4, 2021, 6:50 PM

#

so the UK is the only one it isnt working for?

buoyant lantern Dec 4, 2021, 6:50 PM

#

and germany is a bit offset, since down isn't assigned for some reason

#

But in general, the uk is the biggest problem

#

uks assigned territory is the block in the top left

cosmic basalt Dec 4, 2021, 6:51 PM

#

i would think an easier way to implement that would be to have your country prefab and give it a textmeshpro element in the center

#

and then in your script you can say like country.SetNameText() or something and it would always be in the center

buoyant lantern Dec 4, 2021, 6:51 PM

#

but its a map strategy game, where the text and borders shift because of war.

#

the countrys size will change midgame

#

and the text's position

cosmic basalt Dec 4, 2021, 6:53 PM

#

the text's position can be relative though

#

and it's relative to the exact center by default anyway

buoyant lantern Dec 4, 2021, 6:53 PM

#

but the text meshpro wont scale with the country

#

the country is an empty gameobject

#

storing variables

cosmic basalt Dec 4, 2021, 6:54 PM

#

it can, there is an auto size checkbox on the tmp component

buoyant lantern Dec 4, 2021, 6:54 PM

#

the country stores the provinces belonging to its territory, it itself is empty

#

#

These are just empty

#

Apart from the country script

cosmic basalt Dec 4, 2021, 6:56 PM

#

oh right but the text could be on the province object right

buoyant lantern Dec 4, 2021, 6:56 PM

#

There are multiple province objects making up one country

#

A basic explanation each country has states, the provinces get assigned based on these states, which hold the provinces.

#

#

These are the provinces

You know what would make my life using Unity so much easier?
Being able to click and drag scripts into Lists of interfaces with the SerializeReference attribute. Would make it possible to compose data, like you would with a GameObject.

#

I'm making a dialogue system. I wanna be able to arbitrarily cause certain actions to happen at different points in a line, and no matter how I slice it, the problem I keep running into is that I need to be able to populate a list with a generic type from the inspector, which just isn't possible without getting lost in PopertyDrawer hell.

small badge Dec 4, 2021, 10:57 PM

It's certainly doable; OdinInspector (paid) lets you select types from a dropdown for any list of serialized references. I don't know whether any of its free competitors have the same function yet, though.

you probably shouldn't make language features an integral part of your dialogue system. In particular generics/interfaces aren't the only way to achieve composition.

How would you do it if you had neither generics, abstracts or even objects… it’s possible with just structs and procedures. You are building a data driven system, so worry about the data, not the language features you have available.

#

the best shortcut available is using generics with non-generic base class and ‘concretizising’ them at the end just like you would with MyTypeEvent : UnityEvent<MyType>

question about target framerate

#

if a game has a tick rate of 100 ticks per second with no interpolation, and the monitor is 144hz, is there a difference between setting the target framerate to 100, 200, or 300 [assuming no framerate drops]?

plucky laurel Dec 6, 2021, 4:29 AM

#

yeah without interp there will be frames where nothing moves

lofty inlet Dec 6, 2021, 4:29 AM

#

yes

plucky laurel Dec 6, 2021, 4:29 AM

#

if the game actually gets above 100

lofty inlet Dec 6, 2021, 4:30 AM

#

but I'm saying would there be a difference then

#

between 100, 200, and 300

#

I'm thinking no right?

plucky laurel Dec 6, 2021, 4:30 AM

#

yes you have a weird understanding

lofty inlet Dec 6, 2021, 4:30 AM

#

I'm not too sure how the target frame rate even works - does it limit the amount of frames the screen shows or the amount the game calculates?

plucky laurel Dec 6, 2021, 4:30 AM

#

the principle stays the same, framerate limiter is just limiting

#

so if you have 144hz you are limited to 100 frames, and the result should be same

#

it limits amount of update cycles

lofty inlet Dec 6, 2021, 4:31 AM

#

only visually right

plucky laurel Dec 6, 2021, 4:31 AM

#

nope

#

unity is tied, update loop reflects render loop

#

if you are writing a variable framerate ticker, you have to support that

lofty inlet Dec 6, 2021, 4:32 AM

#

so according to the scenario I gave, even if I had a 300hz monitor and set my target fps to 300 [assuming no fps drops], it would look the same as a 144hz monitor set to 144fps?

plucky laurel Dec 6, 2021, 4:33 AM

#

i dont understand the question, so lets try from another end

#

what do you expect not to work properly

#

what is the actual concern

lofty inlet Dec 6, 2021, 4:33 AM

#

the actual concern is I don't want the user to waste gpu setting the fps to something really high if it is indiscernible from a lower fps that uses less gpu

#

so if 300 target fps and 150 look the same I want to just limit the user to settings the target to 150 max

plucky laurel Dec 6, 2021, 4:34 AM

#

for that the user has settings window

#

where most games have framerate limit

lofty inlet Dec 6, 2021, 4:34 AM

#

yeah I have that

#

but I'm currently allowing them to set it to 400 [that's the max]

plucky laurel Dec 6, 2021, 4:34 AM

#

then set to screen rrate by default and thats it

#

allow unlimited as well

#

its up to user to burn their gpu

lofty inlet Dec 6, 2021, 4:35 AM

#

but they might set it really high thinking it does something

#

when in reality there's no difference

plucky laurel Dec 6, 2021, 4:35 AM

#

then call it for what it is

lofty inlet Dec 6, 2021, 4:35 AM

#

when there could be no difference that is

plucky laurel Dec 6, 2021, 4:35 AM

#

"Framerate limiter"

lofty inlet Dec 6, 2021, 4:35 AM

#

https://docs.unity3d.com/ScriptReference/Application-targetFrameRate.html

#

I'm talking about this...

#

unity calls it target frame rate

plucky laurel Dec 6, 2021, 4:36 AM

#

they can call it that, but its functionally a limiter

#

thats all it does basically as it cant do anything else

lofty inlet Dec 6, 2021, 4:36 AM

#

ok but if the game has no interpolation and has 100 ticks per second, is there a difference between 100fps, 200fps, and 300 fps?

#

I just need to know that

plucky laurel Dec 6, 2021, 4:37 AM

#

in games typically when you actually have a real "target framerate" parameter it implies that the game also has some means to dynamically adjust the settings to maintain it

#

unity doesnt have that

plucky laurel Dec 6, 2021, 4:38 AM

#

lofty inlet ok but if the game has no interpolation and has 100 ticks per second, is there a...

depends on your code. if you allow input to be polled independently of tickrate if the fps is higher, players will experience less input lag

lofty inlet Dec 6, 2021, 4:38 AM

#

yes input is independent of tickrate

abstract folio Dec 6, 2021, 4:38 AM

#

I'm trying to create a package following the steps for "Create Embeded" on this page of the docs..
https://docs.unity3d.com/Manual/CustomPackages.html but when I get to the last step of opening up unity to see it in the package manager- I get this pictured error: Any suggestions/thought on what I might be doing wrong?

plucky laurel Dec 6, 2021, 4:38 AM

#

then yeah, thats all the difference that comes to mind atm

lofty inlet Dec 6, 2021, 4:38 AM

#

oh ok

#

so then actually 200fps would be twice as fast when showing input compared to 100fps

#

and processing input

#

right

plucky laurel Dec 6, 2021, 4:39 AM

#

not really

lofty inlet Dec 6, 2021, 4:39 AM

#

well the time it takes to show the input I mean

#

like if the user opens a menu

#

it will take .01 seconds for one and 0.005 seconds for the other?

#

for the menu to pop up

plucky laurel Dec 6, 2021, 4:40 AM

#

in both cases it can take both amounts

#

it depends on how close the input was in time to the tick

lofty inlet Dec 6, 2021, 4:40 AM

#

well yeah

#

but if they started at the same point

plucky laurel Dec 6, 2021, 4:41 AM

#

i think its related to input window

#

but i cant formulate it, ill go smoke and try to picture the graph in my mind

#

interesting topic

#

ok it makes sense only if the input processing and input reaction locally is independent of the tickrate, like its done in online games, where server has a tickrate, but client reacts to input in update loop, then the perceived input lag is reduced due to prediction

#

i think that if the game locally processes input completely in the tickloop, there will be no difference, whatever the framerate is

#

you can possibly decouple certain systems from tick, like camera movement and ui

lofty inlet Dec 6, 2021, 4:46 AM

#

hmm ok

abstract folio Dec 6, 2021, 4:47 AM

#

"it will take .01 seconds for one and 0.005 seconds for the other? " No- if programmed correctly, it would take X frames at 100fps, and 2X frames at 200fps... which SHOULD be the same amount of time on both systems @lofty inlet

plucky laurel Dec 6, 2021, 4:47 AM

#

it can even introduce more issues with ignored inputs, if you dont buffer input between ticks

#

my advice would be to design it for both lower fps and higher fps without making concrete assumptions

#

tick loop has to run several times a frame if fps is low, and input has to be buffered for cases where its high

    [SerializeField]
    float frequency = 0.9999f;

    public bool randomByPositionFrequences(int seed, float x, float y, float frequency, SeedOffset offset)
    {
        Random.InitState(System.Convert.ToInt32(seed + ((float)offset * x) + ((float)offset * y)));
        return Random.Range(0f, 1f) > frequency;
    }

    void Update()
    {
        timer += Time.deltaTime;
        if (timer > 0.1)
        {
            for (float x = 0; x < 0x64; x++)
                for (float y = 0; y < 0x64; y++)
                    if (randomByPositionFrequences(seed, x, y, frequency, SeedOffset.TREE)) Debug.Log("Tree at " + (new Vector2(x, y)).ToString());
            timer = 0;

Is there a way to assign multiple materials to a procedural mesh?

#

I have it made and ready, but I need a way to properly use submeshes with it, and it doesn't help that the error just says "Failed getting triangles. Submesh index is out of bounds."

#

I set the subMeshIndex to 2, and am assigning geometry to 0 and 1.

#

Essentially, I am trying to assign this material only to the bottom, flat face of this procedurally generated road.

alpine nebula Dec 6, 2021, 7:50 AM

#

where exactly ?

long ivy Dec 6, 2021, 7:51 AM

#

do you mean subMeshCount? if you have 2 submeshes, valid indices are 0 and 1. To assign multiple materials, just use the plural of the renderer material (.sharedMaterials or .materials). Each material is applied to each submesh of the same index

#

long ivy Dec 6, 2021, 7:52 AM

#

yes

static patrol Dec 6, 2021, 7:52 AM

#

I did that. In the MeshRenderer, I assigned two materials, one for each submesh.

long ivy Dec 6, 2021, 7:52 AM

#

confirm that your mesh does actually have submeshes

alpine nebula Dec 6, 2021, 7:53 AM

#

"Failed getting triangles. Submesh index is out of bounds." == try to get one object not allocated

a = array[60]
a[60] == error index is out of bounds

Using Explicit PInvoke in C++ (DllImport Attribute)

Learn more about: Using Explicit PInvoke in C++ (DllImport Attribute)

#

perhaps you need to explicitly declare/use the C++ type

#

Anyway, I'd probably take this issue as a singular data point expressing a "con" (in the pro/con sense of the word) against leveraging C++ and C# in the same application. You might get some benefits from C++ for really heavy duty hot paths, but ... you should probably demonstrate that in whatever benchmarking environment you can put together separately from working on the interop. My personal gut feeling says that C# is pretty fast and should be comparable in terms of performance, and if you really wanna get into the heavy wizardry, you can always explore the unsafe world and do the pointer/memory operations directly

#

Like, there might be better solution paths to getting the performance you need out of C#, and you eliminate the whole class of interop bugs - it's a pretty specific skillset that might be a lot of "pioneers get the arrows" type work.. ie, stepping through c++ to debug issues

#

whereas the collective knowledge of working within one framework is pretty deep, so.. you know, that might be a better class of future problems to solve

you might need to wrap the struct in a managed class in C++

#

https://docs.microsoft.com/en-us/cpp/dotnet/how-to-wrap-native-class-for-use-by-csharp?view=msvc-170

#

my light googling tells me that C++/C# interop using pinvoke is supposed to "just work" but.. i don't know if mapping the C++ object to a different object (even though the floats are both 4 bytes and fields all share the same name, even though one is a class and one is a struct) "just works".. you might need to use the C++ object

misty glade Dec 6, 2021, 6:41 PM

#

this looks like a lot of work 😛

#

In any case, it looks like you need a bit more explicit work to sustain the interop - you probably need a specific class that can marshall in/out calls to your C++ code and objects

#

including just getting the raw pointer and constructing the equivalent C# object

#

maybe someone smarter than me can say if that's the case or not, but ... that's what this looks like (and opinion: i would be a grumpy developer doing it 🙂 )

At the very least your C# class should have an attribute like [StructLayout(LayoutKind.Sequential)] and maybe change it from a class to a struct as well. I also prefer to pass the object as out parameter and assigning it in C++ rather than returning it. The C++ function should take that struct type as a pointer then

I have a menu extension that will call a method to add a gameobject to the hierarchy. That gamobject will be a supplied prefab with a monobehaviour DLL as part of it.
A GO with a script always has the values with it, but I want to convert this to a menu generated and DLL based GO to avoid the play mode.
I thought I would ask this before heading in that direction to make sure of 2 things:
Is this feasible/allowable?
and
If this is the best approach will the gameobject in the hierarchy retain the variable settings of the public input variable types, i.e. selected GOs, floats, bools?
In the previous effort the problem I could not devise a way to menu generate a GO and the settings would store with the GO.

#

I already the GO with the script.

misty glade Dec 6, 2021, 9:02 PM

#

hm, ok, interesting (and imho not a great policy, but that's your choice)

#

I don't think you can do that

#

DLLs have to go specifically into the plugins folder, so you might be able to make some editor methods that move the files there and trigger a recompile

#

but as far as attaching a DLL to a game object... i don't think so, because a DLL is a class library, not just a single class

#

(it might only contain one class, but that's not constrained)

#

Unity's editor would also need to know what the class is that you're trying to attach to a given game object, and I'm not aware of any method of .. uh.. using DLL/plugin classes in the editor to attach a specific component to a game object

#

Opinion mode: it sounds like what you're trying to do is protect your source code from theft, but to be honest, you reduce the value of your asset by doing so - people want access to your source code so they can debug what's busted about it when things go sideways, and offer bugfixes/bugs to you. I would personally never use something that's not open source for this reason, and I don't think most companies/organizations suffer from a loss in revenue from what they're producing by making it open source

#

you're making it a lot more complicated for yourself and your users by trying to do it that way

strong hinge Dec 6, 2021, 9:07 PM

#

Thank you for this guidance. I had gotten this idea then it turned into things to try with the system instead of just GOs and scripts. There are always boundaries to see.

Got a bit of a networking question for unity
Sometime in the future I'd like to implement a sort of noticeboard for my project (What's New, Personalized Messages, etc.), similar to the one used in Genshin Impact for example.
Right now my project works strictly with a PHP server, which is good for quick one-shot requests like pulling user data, but what would I use if I want my game to actively listen to messages from a server? Like say I just released some new batch of news, how would I make it so anybody currently online would instantly have these updated in their noticeboard? And also obviously anybody offline would also see these news when they log in.

There aren't really many other options, but some are listed here:

Push technology

Push technology, or server push, is a style of Internet-based communication where the request for a given transaction is initiated by the publisher or central server. It is contrasted with pull/get, where the request for the transmission of information is initiated by the receiver or client.
Push services are often based on information preferenc...

#

I'd poll whenever the user does something like open an in-game menu. They probably don't want to be bothered with news while they're playing.

opal dawn Dec 7, 2021, 8:53 AM

#

i mean yea, it's all meant to be stuff running in the background and the players would only see the noticeboard if they actively decide to open it

#

this Push tech seems like what i'm looking for, thanks

I have a question regarding assemblies and asset bundles. We have a build system in place for building plugins for our product which works well. I was now playing with plugins/assemblies that depend on another plugin/assembly instead of a plugin only depending on the assemblies in our product itself

#

for that , in TestChild, I referenced the second assembly, TestParent, in the asmdef of TestChild and attempt to build and package it

#

the compilation works well and a dll file is produced. however building of the asset bundle fails

#

"Error building Player because scripts have compile errors in the editor" is the error from the assetbundle building step. There does not seem to be a way to view these errors though

#

there are no errors building the child assembly

#

Do I need to have the TestPArent Assembly in binary form and loaded in the editor? right now that source only lives as source in my project

What's the most elegant way to take a list of transforms and return the transform whose distance to the player's transform is the SMALLEST/GREATEST?

#

transformList.Min(t => Vector3.Distance(t.position, transform.position));

This uses Linq and almost does the job, except it returns the smallest float/distance, instead of the transform that results in the smallest float/distance

#

I'm an idiot, isn't it just "Where" if I'm using Linq? ugh

austere jewel Dec 7, 2021, 11:34 AM

#

Using distance squared and a for loop is how I'd do it. Make an extension method for it if you need it often

ivory eagle Dec 7, 2021, 11:34 AM

#

distance squared?

#

it's just position - position, vector3's

austere jewel Dec 7, 2021, 11:35 AM

#

You don't need to do the square root in the magnitude if you're just comparing. You just care about the relative distances

#

(b - a).sqrMagnitude

ivory eagle Dec 7, 2021, 11:45 AM

#

damn..

Vector3.distance -> (b-a).magnitude

instead of comparing that to some float

I should do

(b-a).sqrMagnitude, and compare THAT to "some float" * "some float"

#

in a for loop!

#

wow

#

Thanks for the tip!

What book would you recommend to learn unity's DOTS?

#

I'm comfortable with c# and reading a book on .NET to extend my knowledge.

#

(Also, i'm currently using a initializer script that FindObjectsByType().each(o.Initialize()) so i can make certain everything is initialized in proper order.
Is this bad practice?

#

I know there's Awake() and Start(), but i find micromanaging it leads to less headache.

I'm loosing my mind. How is it possible for a list of scriptable objects references to have SOME values lost. When the list is deserialized, I loose 90% of the references but a few remain???? The files exist in my folders and the container serialized file contains the guid of these SOs. I imagine it might be because I create and save them from code but... I seem to do every step necessary

did you set the game object that contains the list to dirty before saving or did you change the list via SerializedProperty?

#

if its prefab, did you record the changes?

merry notch Dec 7, 2021, 9:56 PM

#

does anybody know how to access the private field of components?? is it even possible??
Im trying to make a runtime quicksave type mechanic and I dont want to have to program it for every single component

#

are they just blocked off from use?

#

is there any simple way around it? like for example to store the location/rotation/scale of a transform

small badge Dec 7, 2021, 10:03 PM

#

It is possible with reflection, but in general it's better to use public fields in the first place. The whole point of a private field is that you should be able to write code in the class with the assumption that those fields will only be changed in ways and at times that you control. If external code is accessing the class's private fields then that assumption is broken, which is likely to result in bugs.
The location, rotation and scale of a transform, for example, are all public, not private.

merry notch Dec 7, 2021, 10:03 PM

#

those are properties though right

#

I think that should work fine for most things but it would be most robust if it could store the exact state of the object

#

if its possible with reflection lmk how bc using .GetFields(BindingFlags.NonPublic | BindingFlags.Instance) doesn't get anything

small badge Dec 7, 2021, 10:05 PM

#

Even with reflection you won't be able to store the internal state of Unity components that aren't implemented in C#.

merry notch Dec 7, 2021, 10:05 PM

#

thats annoying

#

and disheartening

#

but I should've remembered that they aren't c# objects

austere jewel Dec 7, 2021, 10:05 PM

#

You can get the property values though

#

you should just manually implement which properties are relevant though

#

as many will not be

merry notch Dec 7, 2021, 10:06 PM

#

every

#

all

#

like literally everything

austere jewel Dec 7, 2021, 10:06 PM

#

for example, Renderer.material

#

not something you want to save

merry notch Dec 7, 2021, 10:06 PM

#

hmm

#

maybe im biting off more than I can chew

#

my plan was to only save properties that change

#

yeah properties just completely break everything

iron pagoda Dec 7, 2021, 10:12 PM

#

to answer your original question
the way you retrieve a private field, is by creating a secondary public field, with { get; private set; }

#

or just use that public field itself

iron pagoda Dec 7, 2021, 10:14 PM

so you want a script to read another object's component's properties?

merry notch Dec 7, 2021, 10:14 PM

I basically want to be able to save the exact state of an object

#

kinda like creating an animation on the fly and then being able to play it back

merry notch Dec 7, 2021, 10:15 PM

I wonder if I can use unitys animation system

merry notch Dec 7, 2021, 10:15 PM

#

iron pagoda there are a few ways to achieve that

im listening

iron pagoda Dec 7, 2021, 10:16 PM

#

well, theoretically. I can't say I've done this exact thing.

#

One solution, is perhaps* to instantiate a copy of the object and disable it - might be enough, but not sure if ideal

merry notch Dec 7, 2021, 10:17 PM

#

mmmm

#

interesting

iron pagoda Dec 7, 2021, 10:17 PM

#

The other thing that comes to mind - is JSON serialization

merry notch Dec 7, 2021, 10:18 PM

#

oooo

iron pagoda Dec 7, 2021, 10:18 PM

#

storing GameObjects as JSON

merry notch Dec 7, 2021, 10:18 PM

#

that could work for what I want to do actually

#

but

#

given I dont have to make that json myself and im using some library

#

cuz if I was it would just be the same thing over again

#

https://docs.unity3d.com/ScriptReference/JsonUtility.html

#

interesting

#

we will see if it actually works lmao

iron pagoda Dec 7, 2021, 10:20 PM

#

Good luck :)
If JsonUtility doesn't work like you want it to, there are some other alternatives, though I'm not up to date on which is good or not

merry notch Dec 7, 2021, 10:21 PM

#

I have a inkling that it will just do what my code already does and not actually save the relevant data

#

but I can probably find something better

iron pagoda Dec 7, 2021, 10:21 PM

#

Try searching for Unserializable Properties or something

merry notch Dec 7, 2021, 10:21 PM

#

yeah

#

it doesn't work for engine types at all

#

just gives me an error

iron pagoda Dec 7, 2021, 10:22 PM

#

if it can be serialized, it can be stored in JSON

merry notch Dec 7, 2021, 10:24 PM

#

all I really need to do is what MechAnim does

#

so its got to be possible

iron pagoda Dec 7, 2021, 10:24 PM

#

which is?

merry notch Dec 7, 2021, 10:24 PM

#

just save what properties are changed

iron pagoda Dec 7, 2021, 10:25 PM

#

is it a predictable data set? if so, you can probably just make a function to store them manually

merry notch Dec 7, 2021, 10:26 PM

#

nah

#

a manual function would be too much work

#

and probably break anyway

iron pagoda Dec 7, 2021, 10:26 PM

#

what type of data do you need to store, and also important - why `?

merry notch Dec 7, 2021, 10:26 PM

#

its too much data

merry notch Dec 7, 2021, 10:27 PM

Is there a way to do a shorthand version of the one above? I'm just learning about ternary operators

merry notch Dec 7, 2021, 10:29 PM

#

I could pretty easily make every major relevant system rewind properly but I would lose the ability to make complex effects at all

iron pagoda Dec 7, 2021, 10:29 PM

#

now, I believe you've said two things

Quicksave Feature
Rewind Time (includes animations etc)

merry notch Dec 7, 2021, 10:29 PM

#

I would really want the full rewind time feature but if I can only manage quicksaves it would still be ok

iron pagoda Dec 7, 2021, 10:31 PM

First - look into how to Save a Game State in general - do the same, but don't exit

Sorry, I don't see what ternaries have to do with this code. ?. is the null-forgiving op, which means the instructions on the right of the op won't be run if the instructions on the left evaluate to null.

iron pagoda Dec 7, 2021, 10:32 PM

#

List of Vectors for each frame, point in time OR build an input framework based on System Input Events, using the same mechanic to move forward, as well as back.
For animation - can it be played in reverse?

merry notch Dec 7, 2021, 10:33 PM

I have no idea I might just not both with animations

Right, my apologies, I did mean null conditional. But is there something similar if i'm trying to increment values? Like only += 1 IF != null? but nice and clean like "?"

merry notch Dec 7, 2021, 10:33 PM

#

or make my own simple system

iron pagoda Dec 7, 2021, 10:33 PM

#

using the input event approach would potentially reduce the amount of points in time you'd need to store, if the game is deterministic and Not probabilistic

merry notch Dec 7, 2021, 10:33 PM

#

yeah I wish but I've already made the main mechanics of the game

#

I dont think that its possible to rewind time like that tho 🤔

fresh salmon Dec 7, 2021, 10:34 PM

What error message are you getting on that line?

iron pagoda Dec 7, 2021, 10:35 PM

Yep, that's the shortest you can get to.

merry notch Dec 7, 2021, 10:36 PM

Rewinding Particle Systems

Unity doesn't have built-in support for rewinding particle systems from an initial offset time. Particles systems will ignore attempts to set any negative simulation values and clamp all properties to 0. We can add support

merry notch Dec 7, 2021, 10:37 PM

like if I use a particle effect or trail renderer or any similar effect

iron pagoda Dec 7, 2021, 10:37 PM

Trail might be difficult

#

but let's think like a confidence man for a moment

#

what if you just Snapshot each frame and replay them backwards.

merry notch Dec 7, 2021, 10:38 PM

that was my original idea lmao

iron pagoda Dec 7, 2021, 10:38 PM

if it's a short rewind

xD

merry notch Dec 7, 2021, 10:38 PM

as we found out

an actual picture?*

merry notch Dec 7, 2021, 10:39 PM

actually yeah

merry notch Dec 7, 2021, 10:39 PM

#

id still have to reset the actual gamestate at some point

#

ill need to store every relevant factor inside scripts then

#

its not that big of a deal tbh

iron pagoda Dec 7, 2021, 10:40 PM

#

yes, but you'd only have to store the values at fewer points in time
and if you really want to use smoke and mirrors, you can add a "coming back" effect, to null out any animation discrepancies

merry notch Dec 7, 2021, 10:40 PM

#

the rewinding will take care of itself at that point

#

righttt

#

just flash the screen white or something

#

smart

iron pagoda Dec 7, 2021, 10:41 PM

to pull off
