#

thought the sprites were off center or something

#

but they're correct

tall ferry
#

are u sure that 5/6th one is centered?

rough bolt
#

also if the sprites were wrong it'd show up when the camera wasn't following

#

could you check this one?

#

to be honest I don't think the sprites need to match the transform

tall ferry
#

are u moving the player with the same method? this one looks more clear as to the desync

rough bolt
#

since the sprite has a bobbing effect

#

so it's intentional

#

like the player bobs it's head when walking

#

my main theory is it's just something to do with the camera follow for some reason

tall ferry
#

well yes it is the camera following the transform, which is not aligned exactly with the sprite

rough bolt
#

but that shouldn't cause stutter

#

since the transform is moving smoothly

#

the sprite animation should look the same whether the transform is moving or not

tall ferry
tall ferry
#

remember you arent seeing the transform on screen, u are seeing the visual

rough bolt
tall ferry
#

look at the frames where the red cross is moving and the animation is not, or vice versa. thats the desync im talking about

rough bolt
#

i could test this by removing the animation all together

tall ferry
#

yea try, i suspect itll be smooth

#

if its not, ill be more confused lol but that'd just mean the follow is somehow not on the transform properly. The transform should always be on the same part of your screen.
You can even disable the sprite and just use the red cross, the red cross alone should look smooth but that relies on drawing lines so that should be in the same place your character moves

rough bolt
#

still appears

#

it's for sure something to do with cinemachine and not the animation

tall ferry
#

It could actually be because of MovePosition not happening instantly.. let me try something

rough bolt
#

honestly i have no clue at this point

#

I tried messing with the cinemachine update settings but nothing changes

tall ferry
#

i think im starting to see the issue

#

nvm the more i test the more confused i am

tall ferry
# rough bolt ah ha

idk if u saw as well but even with camera follow in the first half of the video, the transform is still not perfectly aligned

#

then its just especially worse with follow

rough bolt
#

i don't get it

#

I'm only drawing the debug rays in my fixed update

#

oh wait

#

I'm drawing them before my rb.move position

tall ferry
#

oh thatd definitely affect it.. i shouldve realized that

rough bolt
#

i moved the debug draw to after i do my rb.move position

#

so now the debug draw definitely comes after it translates, but it that makes sense

tall ferry
#

what paramaters are u using for those lines?

#

i just wanna make sure its using the actual transform, because its kinda bouncing even when the camera isnt following

rough bolt
# 
    {
        if (CurrentAction != null)
        {
            CurrentAction.FixedUpdate(this);
        }
        else
        {
            PlayAnimation("idle");
        }

        // Draw debug point at character's position
        Debug.DrawRay(transform.position, Vector3.up, Color.red);
        Debug.DrawRay(transform.position, Vector3.down, Color.red);
        Debug.DrawRay(transform.position, Vector3.left, Color.red);
        Debug.DrawRay(transform.position, Vector3.right, Color.red);
    }
tall ferry
rough bolt
#

oh my, I built it, and something strange is happening

tall ferry
#

yea sorry i got no clue because of this video and i gotta sleep. Someone smarter might be able to help but in that vid u can see the horizontal line shifts while the vertical one doesnt.. which doesnt make sense to me

#

its working? honestly its possible that the editor is just slowing it down

rough bolt
#

no

#

🙃

#

that doesn't happen in editor lmao

tall ferry
#

does setting your animation back in fix that?

rough bolt
#

that was with my animation back in

#

anyways, I'll shelve this for now I guess, thanks for the help

tall ferry
rough bolt
#

YO

#

wait

#

I think I got it

#

that's much smoother right?

tall ferry
#

Im on mobile now but that looks way smoother

rough bolt
#

I turned cinemachine's X and Y dampening on the transposer to 0

tall ferry
#

Ohh, guess this wasnt such an advanced issue after all lol

#

Well at least its solved lol

rough bolt
#

guess not Laughing_Facepalm

sweet niche
rough bolt
#

i can finally resume coding

#

that was going to bother me so much if I didn't get it fixed

whole plaza
#

But im glad you figured it out, i would go crazy and just trash the project for a few days

rough bolt
whole plaza
rough bolt
#

it only talks about interpolate

#

doesn't mention cinemachine or dampening

whole plaza
#

i mean that kinda would fix it tho since it smoothes it out the dampening

rough bolt
#

but it doesn't fix it

#

i already had tried interpolate

whole plaza
#

weird it does in 3D

rough bolt
#

is all good though lol

whole plaza
#

2D is wonky i guess

rough bolt
#

am just teasing

whole plaza
#

yeah still

#

wondering how it didnt fix it in 2D

#

when it does in 3D

#

and the article is made for 2D and 3D

#

prolly just unity beeing unity

#

glad you fixed it

#

i will remember the dampening setting if i go to do my 2D minigame for my game should i have that issue

#

are static constructors safe if the first time the class is referenced is from a mono's awake?

untold moth
dusty wigeon
#

A static constructor is always guaranteed to be called before any static function or instance of the class is used, but the InitializeOnLoad attribute ensures that it is called as the editor launches.

buoyant leaf
#

I noticed that trying to set the destination of a nav mesh agent when not on a nav mesh only prints an error message, and it doesn't actualy throw an exception that can be handled

torn rose
# untold moth Safe in what sense?

@untold moth Worried about the constructor being called outside of the main thread. I'm not sure if it is a valid concern. MSDN says static constructors are called the first time the class is referenced.

I read a fairly old thread claiming unity's serialization/deserialization process is done outside of the main thread. I don't think this is a concern since the class itself is static and no instances reside inside a scene, therefore I believe it isn't part of unity's serialization process at all?

If it isn't, then would calling it from awake basically guarantee that it's called from the main thread?

buoyant leaf
#

is that supposed to happen?

dusty wigeon
buoyant leaf
#

shouldn't it just throw a simple exception like everything else

dusty wigeon
dusty wigeon
#

Depends on how things are made.

#

Some return status code.

buoyant leaf
#

java has ruined me I guess

#

C and C++ do status codes, rust does monads, and C# does what ever it wants

upbeat path
buoyant leaf
#

Where else does unity use status codes to indicate an error?

sly grove
buoyant leaf
#

Yeah makes sense

#

I am not saying that it should be an exception, only that I expected it to be an exception like everything else

timber flame
#

Suppose in a voxel based game, there are some items, grasses, flowers, etc. which are not voxel. They can be placed on top of voxels. Now, should I keep their ids in the corresponding elements of 3d array or just for example group id for each type is enough? I think I just want to know if a voxel is occupied or not or for example if characters can pass through it or not. I keep all items in dictionary somewhere else.
It is worth mentioning that pure voxels are stored in 3d array with their ids

analog hazel
#

For a fps game with item spawns for 2-8 players should i use unity networking services or like photon or other stuff? just for close people so

regal lava

kk ty

regal lava
#

Fishnet and mirror are alternatives to a networking library, but they do not offer hosting services like photon.

bleak citrus
#

unless you want to implement your own client prediction and server reconciliation, of course :p

dusty wigeon
regal lava
#

There is actually a large tutorial for implementing the prediction using unity's library on youtube somewhere, but it expands like 40 videos long and no one has time for that.

dusty wigeon
#

Prediction of what ? Movement ? This is like 4 line of code in most network environment.

regal lava
#

Really? Looked rather intensive for what I was looking into

dusty wigeon
#

The issue, is that it can become complex if you want to be perfect. Most people can get away with just offseting with the latency.

bleak citrus
#

well, you have to do client-side prediction, then replay the user's inputs if it turns out that the server disagrees with what you did

#

i guess you can settle for client-side prediction without any reconciliation

#

if the server disagrees, you just get snapped to wherever it said you should be, and that's it

dusty wigeon
#

At least, not for a small game.

#

Made on a corner.

timber flame
#

Non-voxels like items, vegatations, trees, buildings

regal lava
#

Would probably be easier for loading them instead of checking each independent voxel, so perhaps you can do both. Only problem beyond a large lookup table is how you're populating it with the clusters and unloading it all.

#

For my voxel project I kinda just stuffed all the info into each voxel index of my grid

untold moth
plush hare
#

Skipping the rollback phase is going to prevent the client from properly synchronizing. Snapping positions if they differ will not work since the client is predicting into the future.

dusty wigeon
plush hare
#

You're undoubtedly going to experience nasty jittering and teleports when they go out of sync

dusty wigeon
plush hare
#

The server doesn't rollback.

dusty wigeon
#

And, you do not experience nasty jittering nor teleport.

plush hare
#

gonna go ahead and doubt that

dusty wigeon
plush hare
#

Only the clients rollback.

#

Server only ticks forward.

dusty wigeon
#

Network packet can be lost, or slowed.

plush hare
#

not an issue

dusty wigeon
#

And anyway, you wouldnt able to do this on a switch.

plush hare
#

a switch?

#

like a network switch?

dusty wigeon
#

Nintendo Switch

plush hare
#

why not?

dusty wigeon
#

Because we hardly have enough power to run the game...

#

Imagine resimulating the whole thing.

plush hare
#

So just resimulate the local player

#

everything else should be state interpolated

dusty wigeon
#

Which means resimulating multiple frame in one.

plush hare
#

I mean, you do you

dusty wigeon
#

I'm not the one that made the decision anyway.

plush hare
#

Just sounds lazy

#

I'm trying my best to not be an asshole and tell other people their business, but it's just difficult to watch.
If you have a low enough tickrate, you can probably get it down to 2-3 resimulations per tick. If you're just resimulating the local player, that's basically nothing.

dusty wigeon
#

I do not think this is particularly lazy. The solution we currently have does the job for the target market and the budget allocate to the game. It can reach a higher range of console by not having to do heavy calculation that would not matter to the public we are targeting.

plush hare
#

So how does that work?

If your client is predicting tick 100 and tick 95 comes in, are we now just reset to tick 95?

#

Prediction without rollback is basically one giant contradiction and is going to screw with your lag compensation and hit resolution among many other things.

dusty wigeon
#

It is even simpler then that. If the receive position of the client is too far then what his actually position, lerp him back to the server position.

#

This is not made to be perfect. It cost nothing, and most of the time it does nothing.

#

This is a tradeoff between performance, quality and budget.

plush hare
#

So how are you dealing with raycasts over a network?

#

When the clients shoot each other

#

Is it just whatever the server is seeing?

dusty wigeon
#

Pretty much. The other player are being offset by latency which balance a bit this.

#

There is definitely issue with the hit detection, but as I said, this is not a competitive game which means that this is acceptable for most of the player.

#

People (As with low budget / Single Developer) that are making an FPS, does not need Client or Server Reconciliation to make a game. People are still gonna play your game and enjoy it same if you do not have perfect networking.

plush hare
dusty wigeon
#

What people say and what people do is completely two separate world. Take micro-transaction by example.

You have the right to have your opinion, the only thing that I suggest that you consider is how other project are successful same if they have a weak networking. Personally, I would not advice people to invest resources in doing server reconciliation as there is other solution that works and is easier to implement. There so much to be done in a game that would be more important than strong networking.

plush hare
#

Sorry, but if your game has weak networking that leads to shitty hit resolution, then I'm absolutely going to call it out. It's not an opinion. It's a fact that your team is taking shortcuts.

I fail to believe that rolling back and re-applying inputs is so massively heavy on the CPU that it leads to something unplayable. If that's the case, then lower the simulation rate to something appropriate for a switch.

#

I'm going to say this in the nicest way possible, but your network guys have no clue what they're doing.

#

That's about where I'm going to end this conversation, because it's just going in circles.

#

btw for the hit resolution on the server, don't use latency. Let each client tell the server which state they're looking at, and the interpolation alpha. Server can rebuild the client's view based on that. You'll get much more accurate detection.

#

And no, this doesn't open up cheating any more than someone installing an aimbot on their client.

#

anyways best of luck to you man

#

sorry for being an asshole

sleek marsh
#

what could i use as an alternative to UnsafeList?

#

im basically looking for an array version of the UnsafeList - an unsafe collection that lets me write to an arbitrary place in the list

#

(i have an IJobParallelFor that wants to write to this collection)

sly grove
sleek marsh
#

main problem is that burst doesn't want me to have nested native collections

#

in another job i have a NativeArray<UnsafeList>

#

which is fine

#

but NativeArray<NativeArray> it doesnt like

sly grove
#

Why do you need NativeArray<NativeArray>

#

what are you trying to do with that

sleek marsh
#

im generating terrain with marching cubes and each chunk needs to know about its neighboring chunk's information in order to build its own mesh

sly grove
sleek marsh
#

could be thinking about this problem wrong idk

sly grove
#

that allows you to write multiple elements per key

#

(even in parallel)

sleek marsh
#

that would technically work but it seems kinda wasteful

#

compared to if i could get some sort of unsafe array sorta thing

#

the only problem im having with unsafelist is that even if you set its capacity to say 100 for example it doesnt let you access list[50] unless you actually add that many elements to the list

#

which you can imagine is a problem when youre using parallel jobs

sly grove
#

If you know the number in advance why not just a flat nativearray

#

you want a 2D array basically, but under the hood those are just 1D arrays with a little clever indexing math

#

For example - let's say you want 10 arrays with 100 elements each.
That's the same as 1 array with 1000 elements and you reserve 0-99 for the first thread, 100-199 for the second thread, etc..

sleek marsh
#

is there a performant way to join two nativearrays together like that

sly grove
#

WHy would you need to join anything together?

sleek marsh
#

each chunk's voxel data is generated in a native array (with a persistent allocation) then an abritrary amount of time later, its mesh is built using that native array. so if you're saying i should just be using a single native array for multiple chunks, i would need to combine them together before sending them to the mesh building job

sly grove
#

It's a single array, what is to be combined?

sleek marsh
#

1 chunk has 1 array of voxel data, however it must take into account the data of adjacent chunks while building the mesh

sly grove
#

I'm saying put all of the data into one array. Not one array per chunk.

sleek marsh
#

that wouldnt work cuz the world is infinite

#

my code works

#

the problem is that i need to do a seemingly pointless initialization of an UnsafeList by looping through 4096 elements adding empty data before sending it to the job

sly grove
#

obviously you will have to do a little management of your array - assigning chunks to swaths of indices for example

#

comes with the territory of manual memory management

sleek marsh
#

well it WOULD work but the problem is that i'd have to be doing a lot of shifting stuff around on the main thread

#

which is what i want to avoid for performance reasons if possible

#

im comfortable using the unsafe stuff if it means avoiding that because this a very performance heavy part of the game

sly grove
sleek marsh
#

well 50 was just an example

#

but in the actual game each chunk is 16^3 voxels and there are 10^3 chunks

sly grove
#

1000 chunks loaded simultaneously?

#

I'm imagining minecraft here - at worst there'd be around 256 chunks loaded at once in Minecraft

sleek marsh
#

its cubic chunks

#

so a render distance of 5 (in each direciton) would be 10^3 chunks

sly grove
#

Ok but your chunks are smaller than minecraft chunks

sleek marsh
#

believe me i was surprised when i managed to get this to run well lol

#

true they are

sly grove
#

minecraft chunks have 65k blocks

#

it's really the same, your system is just more granular

sleek marsh
#

yeah basically

sleek marsh
#

oh wtf

#

i solved the issue

#

turns out its possible to access the unsafelist.length and actually change it by hand?

#

so i just set it equal to the capacity i needed

#

now it functions identically to an array

#

🙂

Anyone experienced with multitouch? I'm using the "new" input system and have callbacks set up for primary touch position and touch1 position. Sometimes when I start dragging with 2 fingers, and then lift one of them I end up in a state where neither of my callbacks is getting called anymore? Did anyone experience this? Is there a way to use multitouch in the new system like the old one? by just examining touches and how many there are each frame?

compact ingot
tropic stag
#

@compact ingot thanks, I'm debugging now, and if not for the fact that everything works correctly using controller/keyboard I'd start changing my gameplay logic cause the touch inputs are putting my code in impossible states. I think I'm going to have a go of rewriting it with the "enhancedtouch" have you tried that? I just found some tutorial for it allegedly handling multitouch.

compact ingot
tropic stag
#

Well Fingers is only $10, but on the other hand it does a million things I don't need, all I need is a documented touch api that works reliably 😦

compact ingot
tropic stag
#

Well, I already have a simple "gesture" recognition in place, but I started having bugs with my input c# events the moment I added multitouch support. I guess I must be making some assumptions about how the new input touch works, I added primary / touch1 actions for position and press. And it all just behaves "weird" for example I would expect one of my motion callbacks to always log something when a finger is on screen, but with some lifting single fingers while keeping other on screen I get into situations where none of my callback fires... things like that..

compact ingot
tropic stag
#

(ugh, found a bug ( in my code) I was calling a callback on press ended/cancelled for each of the configured touches, and fireing an event, where I should have been doing that only when all fingers stopped touching... it's still a mess, and I should still rewrite it, but it's good enough and I'm having a sort of premiere of my free game in two weeks : ) anyway, thanks for the support @compact ingot for future reference you've since got and used the Fingers asset and can recommend it?

That's what I did 🙃
Unfortunately, I could not find the cause.
Although I did find out the issue was due to the pathfinding code I was using.
I'm trying to create a Civilization-esque system where the player can select a unit and move it to a different cell. Previously, I was using the A* algorithm which took 2 cells and tried to find a path between them. But then I also wanted to show all the possible cells where the selected unit could move, and for that I had to use Breadth First Search. So, I ditched A* and just used BFS for pathfinding as well.
The issue does not occur anymore. (But I still don't know why it was happening before).
Anyway, Thanks for the help @scenic forge @dusty wigeon @bleak citrus @compact ingot @sly grove

whats the best way to save and load scenes
save everything in the scene as it is, all the changes, movements, traps or whatever, and then load it with a button in the previous scene

sharp imp
#

Anyone knows how to tweak OnDrag pointer event sensitivity? I am implementing IDragHandler and it seems like when I press button and move mouse, the OnDrag is not triggered immediately, I have to be a certain distance from the original pointer position to trigger and in my case for some reason the distance is quite long so it feels like there is a lag.

sly grove
#

Saving the "entire scene" isn't really a thing nor would it be efficient.

bleak citrus
#

it's a very broad question

#

especially if you're talking about changes relative to the original scene

#

e.g. recording that a specific enemy from the original scene is now standing in a different position

#

i imagine it's a lot simpler to just make a big list of every enemy that's currently in the scene and recording that information

Hello! I have a problem with credentials in WebGL requests.

I have Set-Cookie .AspNetCore.Identity.Application=CfDJ8KibhKtdp... in one request and "credentials" set to "include" (127.0.0.1:10203/ns/login)
And in the later request to the (127.0.0.1:10203/ns/projects) I see no cookies set and "credentials" is set to "include" too

I don't see anything related to credentials in the Headers, if it needs to be there
In Unity there appears to be no Set-Cookies either

What should I do to make cookie be set in the (127.0.0.1:10203/ns/projects) reqeust?

hey: is it uncommon to make use of allocator.persistent at all? im Disposing the nativearray when OnDestroy() is called. i can find only 4 google pages for "allocator.persistent" and most of them are dealing with bugs. so i thought of recreating the transformaccssessarray every time im using it, but where is the sense of recreating the entire array every frame to move my transforms like this: transforms[] -> nativearray-> setting the transforms ? wouldnt this cause even more overhead/garbage, or will just refernce the original items of the original array? i mean its ok as long as i am not using any other jobs, or physics events that interact with the gameObjects moved by the transformaccsessarray. this is the warning which is most likely caused by a bug, or incompatible package: ````Internal: JobTempAlloc has allocations that are more than the maximum lifespan of 4 frames old - this is not allowed and likely a leak

To Debug, run app with -diag-job-temp-memory-leak-validation cmd line argument. This will output the callstacks of the leaked allocations. so where can i see the leaked allocations? in the debugger?

stiff hornet
#

well then it's probably an internal Unity leak

#

or check the profiler and see if that job is taking too long (over four frames)

crystal wasp
#

warning says internal (only thrown if this job is fired), but the problem is that physics events will cause crahes (like physics.overlapsphere). but let me check the profiler

stiff hornet
#

I've just noticed the last line

#

you are setting it to a local variable

#

which means the LateUpdate is not force completing the job

#

which could cause the job to go over four mainthread frames, if the main thread is running fast

remove the JobHandle so its not a local variable

i think this is a bug. i actually have another job float timer=0f; void Update(){ if(timer<1f){ timer+=Time.deltaTime; } else{ timer=0; var commands = new NativeArray<OverlapSphereCommand>(1, Allocator.TempJob); var results = new NativeArray<ColliderHit>(3, Allocator.TempJob); commands[0] = new OverlapSphereCommand(centerObject.transform.position, 10f, QueryParameters.Default); OverlapSphereCommand.ScheduleBatch(commands, results, 1, 3).Complete(); if(results.Length>0){ foreach (var hit in results) { if(hit.instanceID==0)return; Debug.Log(hit.collider.name); } } commands.Dispose(); results.Dispose(); } } but that really dont make any sense at all. the memory leak-warning is only thrown if both jobs are running. (even if theres no interaction at all). ill try overlapboxcommand, i really dont know what to do from here, besides recreating this in a testscene. can Profilermarker help to find the source of evil here?

what happens after the foreach

...

crystal wasp

it doesnt matter if i use break instead

stiff hornet
#

it should

#

you don't do the dispose when you return; which then leaks

crystal wasp

ahhhh

but you don't need to dispose for Temp. Also persistent unless you need to (like in destroy)

#

If you were using Entities then you'd use the World Allocator instead of TempJob

#

then you wouldnt need to dispose then either

#

thats why you don't really see a lot of people use using, at least i don't

Hey everyone, how can I prevent breaking on exceptions while debugging in Rider?
In my main project, I have a tool installed which always throws when exiting play mode and I would like to ignore it.

dusty wigeon
#

In visual studio, that would be break on exception. (Given that you did not place a break point yourself). I guess there is the same in Rider.

Can you suggest me a good way to handle it?
In my voxel game, there are some rivers, they flow gradually. I have to update voxels and generate chunk mesh in every step but it is time consuming.
A simple way is not to regenerate chunk mesh in every step.
Another option is to regenerate meshes just when they get visible.
or create different meshes for water voxels completely separate from other voxels.
Chunk = Water mesh + Main mesh

this is weird... seems like Start happens in the same frame as when the component is being enabled. this is not according to the docs ...

#

either that or im missing something very important here

austere jewel
#

The docs do not show start or awake in the update loop, they just say:

For objects that are part of a scene asset, the Start function is called on all scripts before Update, etc is called for any of them. Naturally, this cannot be enforced when you instantiate an object during gameplay.

Hi, I have communication via SerialPort (consoleApp works fine) but if I put into unity event "DataReceived" not fired although serialBuffer have data

    {
        this.m_SerialPort = new SerialPort();
        this.m_SerialPort.PortName = this.m_COMPort;
        this.m_SerialPort.BaudRate = 9600;
        this.m_SerialPort.DataBits = 8;
        this.m_SerialPort.StopBits = StopBits.One;
        this.m_SerialPort.Parity = Parity.None;
        this.m_SerialPort.Handshake = Handshake.RequestToSend;
        this.m_SerialPort.DtrEnable = true;
        this.m_SerialPort.RtsEnable = true;

        this.m_SerialPort.ReadTimeout = 0;
        this.m_SerialPort.WriteTimeout = -1;

        this.m_SerialPort.DataReceived += this.DataReceivedHandler;

        this.m_SerialPort.Open();
    }

 private void DataReceivedHandler(object sender, SerialDataReceivedEventArgs e)
    {
        print("přijem!");
        SerialPort lSerialPort = (SerialPort)sender;

        byte[] lBuffer = new byte[lSerialPort.BytesToRead];
        lSerialPort.Read(lBuffer, 0, lBuffer.Length);

        this.m_Command.AddToBuffer(lBuffer);
    }```
#

Or if it won't be better to simply create a coroutine that checks the buffer and reads and not rely on the event?

is having everything in one item class the norm ?, I plan to have 3 kind of item, these 3 doesnt share many things so my current code have a lot of empty return. easy to code but quite ugly

untold moth
white raft
#

yes actually considering using interface but "this cant be the right way". tutorials usually use this architecture, and I havent find proper one

untold moth
#

I mean, you'd usually have a base class with the common functions, then the subclasses only override stuff they need to override.

white raft
#

for more context, i have item that can only be placed on floor, on a surface, and normal item

#

these 3 basically only share inventory icon but if i want to check an item i couldnt check the right class

#

havent figure it out other than mark it with a string then check the string then check any of 3

untold moth
#

I'm sure items have at least some other common properties. Either way, that doesn't sound like an advanced question.

true i guess, cannot find stuff i want so i put it here my bad

i want to convert a patrol/chase/attack state machine into GOAP. There should be actions like MoveToPoint, DealDamage. I dont get how i would set goals, preconditions and effects. Let's say an agent only wants to patrol. What would the sequence look like? The picture is how I would do it. But the SetTargetPoint action should be later reused for finding what to chase, for example. If i make a lot of set point actions then the amount of states also increases and it just seems wrong.

'when does it make sense to use this?' is an important part of understanding tools

#

trying to use a hammer to screw in a nail will teach you something but it's not how i'd recommend learning

vale spindle
#

okay what should i start with then? it's not about having state machine as a base, it's just a simple example

cursive horizon
vale spindle
cursive horizon
#

what plan is required for following a patrol route? the plan is just...follow the route

#

same for something like 'chase target'

#

goap is essentially a pathfinding algorithm that can include things other than pathfinding nodes, which is cool! but if all you need is pathfinding in the world, and not across a set of actions/outcomes, goap is way overkill

#

often it makes sense to do both -- you want your mobs to have heavily scripted patrol paths, target acquisition, etc. so that the player can predict and interact with those things

#

but maybe once your ai is in the combat state, it can switch to a goap planner with some interesting goals

#

what those can be and how interesting they are will depend a lot on the environment you are building in your game though

#

there's a reason goap isn't super popular used all the time everywhere despite how cool it is

bleak citrus
#

i should really just read about it lol

cursive horizon
#

it's very cool but ultimately having things in your game act in unpredictable ways is often not what you want

#

in most cases it ends up being cleaner (and more performant)to just script a few different 'plans' and select one versus doing that in realtime all over the place

#

you need a fairly complex environment before it becomes worth it to let your agents come up with their own plans and at that point it becomes difficult to do important stuff like...balance your game, because your main tool for doing that is changing the environment itself, which is a lot of work

i'm working on an AI for a survival horror game

cursive horizon
#

it's a good resource for seeing what kinds of goals/actions make sense and all that

bleak citrus
#

i do want to start moving towards more complex interactions than "investigate the most interesting sound/sight"

cursive horizon
vale spindle
cursive horizon
#

the important thing is having clear goals so that you can tell whether that time was well spent, what improved/didn't, etc.

bleak citrus
#

for example, if you throw a rock to distract it, and it finds nothing after investigating the "rock falling" noise, it should gradually start ignoring the noise

cursive horizon
#

ah not quite in the same way

bleak citrus
#

that's also probably not GOAP anyway

#

it sounds like "goal-oriented" really kicks in when you have complex chains of logic

#

like, the enemy wants to trap the player, so the enemy starts barricading doors and stuff

cursive horizon
#

yeah, do you want your ai to come up with and execute complex multi-step plans? but in a lot of cases i feel like you may as well just script a 'barricading room' state

#

especially because for goap to be useful, you kind of want a complex environment? but the more complex your environment is, the more frequently plans will be invalidated and need to be replanned

bleak citrus
#

one thing I want to tackle first is "cutting off" the player

cursive horizon
#

ultimately you kind of want your ai to be predictable because otherwise the game is too hard

bleak citrus
#

player goes into room with two exits -> go to the other exit

cursive horizon
#

haha

bleak citrus
#

i can't remember how to do the math for intercepting a projectile

cursive horizon
#

see a lot of stealth games intentionally prevent mobs from being mean like that

bleak citrus
#

god knows how i'm gonna do this one

cursive horizon
#

depends on the vibe you are going for

bleak citrus
#

i feel like i need to calculate how far the player could possibly be from the starting location at different times

#

and then find a spot the enemy can reach at the same time (or sooner)

cursive horizon
#

but it can be very easy to put a lot of work into making the player's life miserable and then succeeding and being like 'shit'

bleak citrus
#

lol

cursive horizon
#

unless i have some way to clearly know that that zombie is flanking around to cut me off, i am going to call bullshit when it happens

bleak citrus
#

I'm going for an Alien: Isolation vibe, so I do want the enemy to be very threatening and a little unpredictable

#

it's one enemy, not 100 dudes

cursive horizon
#

oh nice, ok yeah

bleak citrus
#

i figure I can slap a big dial on the AI that controls how likely it is to be "weird"

cursive horizon
#

i really like goap for that case then

bleak citrus
#

since there's just One Of Them

cursive horizon
#

since the environment won't actually be that dynamic and the player hopefully has enough bandwidth to actually understand this one individual and how they behave

#

yeah good stuff

#

i bet A:I cheats though

#

i doubt they are calculating the timing for the alien to cut you off or whatever

#

they just decide whether it will and then let it reach where it needs to go, physics be damned

#

much easier

bleak citrus
#

lol, yeah

cursive horizon
#

i really like the idea of 'manipulating' the enemy in a way that goap kind of allows though

#

like let me steal someone's weapon and then startle them so they go grab another nearby weapon which i have booby trapped

#

it opens up some interesting interactions which make the player feel clever but of course you can just script those

bleak citrus
#

yeah

cursive horizon
bleak citrus
#

the platonic ideal is that your enemies have a bunch of little behaviors that all mesh together properly

Need some advice/opinion:
What's a good role title in a job ad for a person that would do a lot of rendering optimisation, shader fine-tuning, asset pipeline optimisation, and general URP wizardry?

"Tech Art" feels too vague (and some on the pure programming skew see "art" and feel mismatched)
"Rendering Engineer" maybe, but some people seem to get confused by the term "engineer".

untold moth
bleak citrus
#

my immediate reaction would be "technical artist"

#

but you mentioned that

hardy sentinel
#

if you want the title to be descriptive enough so people that aren't qualified would not even read the description, you could just make it Rendering Optimizations Engineer

#

but be mindful, that'll reduce the applications by a shitton amount

#

If you think this is not an advanced position, write 'Designer - Unity (URP Shaders)'

My closest finding so far is this repo: https://github.com/gtalarico/ironpython-stubs
Using this I may can generate python stub files from the C# classes.

Good morning, any one knows how to further compress TextAssets to reduce build size? I have around 30mb in texts assets (.csv) with levels in different languages (its a word game)

i have tried different compression softwares to try compress them beforehand but the resulting size is very similar... i guess im looking for magic 😆

Different compression software's wont really do much

one file for each language

would there be a better way of storing it thatn a csv? i already minified the files

From what I saw online unity does have a localization package, although I have no clue how it is because I've never used it. That might be able to help with your issue

It does say you need csv or some other format for it though..

without implementing download of content

If movement is grid-based, you can create some simple graph and use any pathfinding algorithm. If the movement is free, then probably it's better to use NavMesh as suggested above.

From my experience (I do not have a lot), Video Game Industries as a programmer can be tricky to get in. There is a lot of "self taught" programmer, but with the except of a few, most of them accomplish nothing that is worth considering.

In my opinion, if you really want to get into video game, you should consider certification (1 - 2 years). Those certification helps build a portfolio while also acquiring a variety of skills that are directly applicable. Where I work, 3/4 of the people that has been judge qualified enough have done those certification. I feel like video game education has evolved these past years and the quality of education you can get is now higher.

Note: Multiple bachelors and master has applied, and with the exception of 2, none were qualified. Lack in understanding of video game concept was one of the reason why. (They were not able to find the closest point in list. )

whether you can get a job depends a lot on your location, game studios are swamped in applications of clueless people (everyone applies to every job offer disregarding any requirements) so to actually get even an interview you need to have a believable resume and can demonstrate competence in a screening call within minutes, this is difficult to fake. Its considerably easier to land a unity job at a mobile studio over a AAA job doing C++ in an in-house engine. Best/most predictable path is an internship and practicing by making challenging projects in the meantime. Most of what studios are looking for in skills is not the easy stuff that is fun to do. They want you to be able to connect your work with that of others, deal with integrations and pipeline issues, tools and conceptual things that are part of operating/releasing games. You are often left alone in understaffed teams, so being able to pivot quickly between problems and having strong fundamentals is key. Anyone can implement gameplay features. Few can do it performantly, fewer still can do it productively in a team running a live game.

I need some help with UnityEvent...

I'm invoking a UnityEvent<string>, and I want to use that string value to update an UI element.
I've added an event listener to my UI element so I can call a function to update the value on the UI element to my UnityEvent string value.
But for some reason the value stays empty, so it throws an error because the string is empty

dusty wigeon
#

When configuring a UnityEvent in the Inspector there are two types of function calls that are supported:

Static calls are preconfigured calls, with preconfigured values that are set in the UI
. This means that when the callback is invoked, the target function is invoked with the argument that has been entered into the UI.
Dynamic calls are invoked using an argument that is sent from code, and this is bound to the type of UnityEvent that is being invoked. The UI filters the callbacks and only shows the dynamic calls that are valid for the UnityEvent.

It's unclear in your example what is a placeholder and what is a generic type parameter etc

for example you would never do new Example<T>(GetComponent<ScriptType>())

You would have to do

Or rather

you may be confusing the T from your method with the T from your class definition

Hello! Does Unity have a callback at the start of the build process, which would let me insert my own custom build step into the pipeline? I’m hoping to bake some data down, per GameObject. But it would only be safe to do so right before I standalone build is made.

#

I could make this build step a manual process, that’s kicked off from a menu item. But it would be nice (and less error prone) to always run it as part of the build pipeline.

  1. How can I change the window title during Runtime? Like "GameName (Not Responding)". I want to do some sort of cool trick if it's possible.

  2. How to create software gore? I want the UI and controls to be messed up in all sorts of ways, while also adding glitchy movies and pictures

#

is there a way to check sum my entire game while it is running

#

it will be about or below one gb, I want to run a checksum or similar on it to prevent cheating in competitive modes

dusty wigeon
#

Also, you would not be able to checksum the memory of your game.

#

The only way I see that a sort of checksum could be useful is after loading an asset. It would be an easy way to prevent the least competent/motivate hacker to cheat, but it would not prevent them entirely.

#

on it to prevent cheating in competitive modes

honest agate
dusty wigeon
#

This is all about how you "load" mods.

#

If you load a mod, then refuse the access to the server.

honest agate
#

I plan to have it on steam and oculus

#

steam has workshop but oculus not so much

#

oculus has a crap policy on modding

#

I fear that my game wont ever make it on the oculus store if say i put a folder in the game files where you can drag in various mods and the game will load them

tired creek
#

If I use C++/CLI stuff like System::String^ to build DLL that I will use in my Unity game, will the game work if I build it for Linux?

there is no other way.

dusty wigeon
#

Even that cannot prevent every type of cheat.

#

Like Aimbot.

plush hare
#

If we're talking about aimbot and stuff then yeah

#

no way to prevent that

dusty wigeon
#

See through wall

honest agate
#

maybe ill cross that bridge when i come to it

plush hare
#

if he wants to cheat, nothing will prevent that

#

If host doesn't have authority, then anyone can cheat at will

#

like GTA V

honest agate
#

so the host was gonna have authority over the ball

#

and the players 2-4 will have their balls set according to the physics the host has calculated

#

but i need to know if the host is using mods or cheating

#

so i wanted to verify the files of the game with a check sum

plush hare
#

you're gonna ban players for cheating on a p2p game?

honest agate
#

so the host can have a mods tag in the host list

honest agate
plush hare
#

ah

honest agate
#

If you want vanilla, you can know ahead of time if it is modded or vanilla

#

so how could i detect if it is modded

plush hare
#

the host needs to specify that when he's starting the server

#

trying to stealthily detect this is pointless

honest agate
#

but what if he doesnt

plush hare
#

you need to understand the term "never trust the client".

#

anyone can modify the client

#

your checksums will do nothing against someone whose going to make cheats/mods for your game

#

and actively wants to avoid it

honest agate
#

hm

#

i should ask around the beatsaber modding community

plush hare
#

you're fighting an impossible problem

honest agate
#

the meta headsets automatically detect the beat saber clients that are modded and display a popup

honest agate
plush hare
#

You can't do anything. If people want to cheat, they're going to cheat.

#

especially in a p2p scenario where players are the server

honest agate
#

alright, thx

plush hare
#

Payday 2 marks people as cheaters based on the mods they have installed

#

but again, nothing preventing someone from making it undetectable

#

save yourself the time and just let each client broadcast which mods they're using.

#

you can build it into the game so they don't have a choice.

tall ferry
# honest agate the meta headsets automatically detect the beat saber clients that are modded an...

you can attempt to detect modded clients by making your client send a specific key to the server, if that key does not match what is supposed to be sent then you know its modded. This will deter some individuals but if an attacker knows what they're doing and really wants to mod, this will not stop them at all. Itll only really stop people who dont know what they're doing, but might as well stop them too rather than not use anything.
If you've heard of the game, osrs tried to implement this and literally the same day it got implemented, people found what the key was.

honest agate
#

and having a separate lobby list for modded/cheating

#

The open source version will have a different key

#

maybe i can change the key every update

#

this would also prevent out of date clients

plush hare
#

Why is it so problematic if the host is running mods?

honest agate
#

this is p2p so im not sure how well relay will like keys

plush hare
#

Each client should be able to just ignore it

honest agate
plush hare
#

that's not gonna happen on P2P

#

people will cheat

tall ferry
#

is there any reason you want to open source it as well?

#

thatll just let people know which areas arent protected against packets

plush hare
#

you're underestimating the amount of people that just go around fucking with other people for the sake of being bored

honest agate
#

i dont wanna use server infrastructure because of cost

plush hare
#

you can very easily run hundreds of your pong instance on a single VPS

#

for like $20 a month

tall ferry
#

its possible to open source some things yet keep your key secret. But also updating your key every update wont change anything

honest agate
#

maybe i can just go p2p with no rank system, if the game sees some success and revenue i can transfer

honest agate
plush hare
tall ferry
#

I wouldnt take away the rank system entirely because of hackers possibly existing

honest agate
#

could i use the unity gaming services or do they not offer vps

plush hare
#

it would probably be more expensive

honest agate
#

ah ok

#

just for reference

plush hare
#

OVH is so cheap because they hardly manage anything

#

they just spin up a box and give you SSH

honest agate
#

I would be transferring 3 vector3 transforms, 3 euler rotations, and a handful of various other values with each update

plush hare
#

You could probably also pay by the hour/hardware used per month

#

that's pretty inexpensive

honest agate

Im still a bit new to mp

I made an A* algorithm that finds the player in a 2D space and placed it on my enemies. The problem is that my 2D space is side view and I can't completely use this A* because the enemies will fly instead of walking, taking the shortest path. I want them to walk. I think the easier way out would be to change the heuristic function for the path generator to stay closer to the ground. I tried to take every position and go to the lowest tile that is above ground and somewhat works (this is the green path). In the image bellow Player's location is the green circle and the red circle are the enemies. With the A* it will take the red path. If I try the solution above it will take the green path. I want to make it go the yellow path or something that feels more natural than the green path. Any package or asset will not be helpful, I want to make my own. Any ideas?

image.png
plush hare
brisk stone
tiny pewter
#

this is heuristic function

brisk stone
tiny pewter
#

check whether the cell underneath is ground (or whatever the enemy can walk)

plush hare
#

yeah

#

that's pretty much the most straightforward way

brisk stone
#

I did just that and I got the green path

tiny pewter
#

is yes, then explore it, no then mark it unwalkable

plush hare
#

It needs full knowledge of what is a floor/ceiling/wall

brisk stone
#

Ah. I have to do that when I explore. I did not think of that.

#

So basically mark everything that is not walkable as wall?

plush hare
#

Like, once you know where your floors and walls lie, you can just run the A* algorithm against that

#

against those lines

#

someone with more knowledge on pathfinding might have a much better answer than me

tiny pewter
#

i realize checking the cell underneath is not working since the character may jump

plush hare
#

Right now, you could definitely try a steering behavior with gravity and such

#

instead of just forcing the position

#

that way he's forced to fall down

tiny pewter
#

how about have a heuristic to give you a lower score if you are close to ground

plush hare
#

I could see that failing in different levels

tiny pewter
#

maybe some exponential function that can give a significant different between different height

plush hare
#

honestly pulling your AI down with gravity and recalculating on an interval would probably solve this

#

assuming gravity is a thing in your game

tiny pewter
#

yes, i believe gravity is a easier way rather than path finding

brisk stone
#

I will try to play with it a little

plush hare
#

like I said, you'll probably want a steering behavior. So a rigidbody is probably the best for this

#

then you can give it a brain, raycast infront, check if it needs to jump, etc

#

you should probably also include some state data like waypoints hit, so that it knows where it's been and doesn't try to reverse

calm ocean
#

I don't know if this is the right place, but I need an undo operation to work for both destroying an object and also the data structure for keeping track of the position of those objects.

        public void RemoveTileAt(Vector2Int pos)
        {
            GameObject tile = _tileGrid.GetTileAt(pos);
            if (tile == null)
            {
                return;
            }
            
            RemoveTilePieceAt(tile);
            #if UNITY_EDITOR
                Undo.DestroyObjectImmediate(tile);
            #else
                DestroyImmediate(tile);
            #endif
            Undo.RecordObject(gameObject, "Undo Tile Grid Remove");
            _tileGrid.RemoveTileAt(pos);
        }
#

The intended behaviour is that when I remove a tile, the game object is removed, and the tile grid no longer keeps track of the position of that tile. And when I hit undo, the game object is back to where it was, and the tile grid is keeping track of the position of that tile again

#

As of now, when I hit undo, the game object is back to where it was, but the tile grid no longer keeps track of the position of that tile again

tiny pewter
#

you need stack

calm ocean

The _tileGrid is a serializable class.

Hi guys! A little new here but does anyone have any good places to start on how to design a CutsceneManager for a game? So far I've broken the system of the manager down and have a queue of CutsceneSteps which can extend to stuff like dialogue and switching the camera.

I'm also trying to make a custom editor tool inside of the inspector where u select the type of step that is needed and it would give you a list of variables to fill up (e.g. Camera if needing to switch camera, or TextAsset if its a dialogue step) if anyone has any information on how to start something like this would really appreciate it! 🙏

There are packages, but you can make this by hand.
Right now (I think) you're treating it like a top down map. All you need to do is check which direction you can move from each tile. So you can go down the wall, or maybe diagonally down if you can steer while falling, but you can only go across or up if you're near a floor.
That will give you a collection of tiles (or nodes) and connections.
Then you run normal A* and you should get the yellow path.

#

If you want to, you can then weight going upwards or jumping to be more expensive than going across the ground, so they'll prefer to walk.

#

(And can vary that to make enemies that prefer to fly, walk on the ceiling etc.)

obtuse remnant
#

Better to make it easier on yourself and get a working project, instead of trying to plan too much and never get finished.

#

"Good enough is good enough."

#

And if you decide to change later, you'll know why you need to and understand what you're doing. So it's not wasted work.

# honest agate so i wanted to verify the files of the game with a check sum

As people said, you can't verify if the host is cheating.
But for a physics game like ping pong, you can have the clients also calculate the ball.
When the host sends updates, the clients check if they agree.
The host and clients won't perfectly agree, because of slight delays, but it should be close.
When the host sends a reasonable update, the clients can match to it so they stay similar enough.
If they disagree, the client should disconnect. Pretend it's a time out or something.
You won't know if it was the host or client cheating, but it stops the cheaters playing with others who don't have the same mods.
(And there's always more ways to cheat, always.)

#

(Cheating or stopping cheaters is always a question of "is it worth the effort?")

I'm hiring a junior to teach, not because of how good they already are.
So the best thing you can show is that you can learn and adapt to how other people want to work.
You need a portfolio, showing nice clear examples of the work you think you're best at.
And showing your overall skills.
Often I'll see an example and ask "oh, have you done much with maps and procedural generation?" or whatever, so you want to show the range of what you've done.
If you can, show team projects, even if it's just a side project you make with other people here. Clearly state what part you worked on - showing you worked in a team is a good thing, I want to see you saying when others did the work. It shows I can believe you about the things you say you did.
But focus on one nice, easy to show visually, example that you'll try to get in front of people.

#

And don't quit your job!

#

Write code to do those calculations you don't like doing. Put that onto your resume!
I already had 20 years experience and was team lead of enterprise systems development.
It took me years to get a good job. "No industry experience"
You will be competing with people who've gone to university AND already have a portfolio of group work from their courses.
So start making games.
Build a portfolio and start applying.
But keep your job because even if you're really good it could easily take 5+ years to get that first real break.

I was planning on doing that, I just wasn't sure the best way to handle separate brick data. I want to be able to have separate events, properties, and interactions, as well as rendering. I wasn't sure that each chunk should really be a GameObject, I thought that perhaps chunks could benefit from being Entities somehow. By the way, if you're looking for a developer, I could use a job. I've been programming professionally for around 6 years now, and have experience with various teams and projects, even commercial Steam products for both Unity and Unreal.

obtuse remnant
#

I mean, the answer is you shouldn't use game objects.
But it's better to use them and get it working, learn about your project and what your needs are, etc. rather than over complicating things and getting stuck.

#

But I'd try to find a good voxel engine, because it should have already solved this for you.

Ah, shoot. Had to try.

Anyways, yeah I don't think I want to use GameObjects for sure. I was thinking that chunks could be entities, I though they could be useful. I wondered if ECS would help process chunks faster, and allow them to be in and render in-scene with less overhead. I was also planning on using the Job System + Burst for mesh generation. The last time I wrote a "brick engine" like this, I multithreaded it with normal System.Threading methods, but I think it might be more efficient to just use Jobs + Burst this time.

obtuse remnant
#

You miss every shot you don't take! It would be silly not to ask!

hollow veldt
#

I've been thinking that more and more lately ^

#

If nothing else, I might just reduce myself to hyper-casual apps for a while.

obtuse remnant
#

But I've never done it myself, and don't know if it's "nice to have" or absolutely necessary.

hollow veldt
#

I've experimented with ECS, but I never had a solid reason to get deeper into it until now. My basic implementation was the Lorenz attractor displayed with entities. It performed decently.

#

I would like to show people that Unity is capable of greatness and abundance. Many onlookers have the idea that Unity is bad, and slow, and for beginners, and that saddens me because I know better.

obtuse remnant
#

But work on the stuff you want to do, at least enough to show in a portfolio, so you can keep applying for those roles.

hollow veldt
#

Yeah, I need to update my portfolio site soon, it's becoming a tad dated

obtuse remnant
#

I cheat. I leave my portfolio clearly unfinished, so that I can bullet point list topics and skills "that I still need to add"
Let's me at least mention them, even if I don't have a demonstration. They can always ask about it at an interview.

#

And they're not hiring me for professional website design.

#

Games dev is so broad, we could spend years on a portfolio and not cover the right topics. And they're not going to dig through looking for your work.
You really just want a good first impression, and maybe highlight a few key skills.

https://youtu.be/Yl4a-1FtXqQ I once came up with this cool voxel meshing method that pre-cached the voxel edge case meshes ahead of time so it didn't have to calculate what it needed to be based on its neighbors, and it was faster than any other voxel method i'd implemented before. Unfortunately, and to this day I'm still sad about this, I lost it all in a drive issue before I managed to back it up..

How would I go about assigning different materials/shaders and physics materials to different voxel faces in a procedural mesh?

compact ingot
round pawn
#

Oof

compact ingot
#

you could for example encode your physics material into vertex colors or a splatmap together with the shader data

obtuse remnant
#

And your shader can paint it differently depending on the angle. So you could have grass on the top and rocks on the side and bottom, letting you make terrain from the one voxel block.

#

But I think you'd normally use a different voxel for something substantially different. Like grass vs sand.

#

For something like lego you could probably use raymarching so the voxels can just be cubes, but you still render the knobbly bits or hollow insides.

If you deallocate it should be available immediately (I believe...)

Also, if the array uses value types and is a local variable in a method, it can stay on the stack and is automagically freed when the method exits.

A* is pretty fast and shouldn't be lagging you. But if you're calculating the path from the enemy to every square that you check then you'll be calculating WAY more paths.

#

You can use node weights to cache a value of how safe it is, and pre calculate dead ends.
You obviously can't pre calculate enemy positions, but you can calculate it, store it in the node weights, and update occasionally.
Once that's set up you can use normal a* pathfinding, or better yet, a least cost walk, to pick your path.

obtuse remnant
#

There's different ways you can do it, but as one example imagine if you store the cost of enemies in the node, and every time you calculate you set the cost for the cell the enemies are in to 10
Then any cells connected to those gets set to 9. Any connected to those gets set to 8, and so on.

#

You can even show it visually by colouring the nodes. Helps you see where the AI will want to move.

#

And you don't have to calculate it every frame.
It will get out of date as enemies move, but will be accurate enough that it will still give similar results as long as you recalculate before the enemies move too far.

Hey-o, so I am doing some mesh generation with jobs, I am generating it and need to do some 'post processing' on it (like bending it). I was wondering if it would be faster to do the generation and modification in the same job, so only loop over the vertices once, or would it be faster to have two jobs, one to generate, and after that is finished, a second job that modifies the mesh? This would be 2 loops over the vertices, but each would be doing less, but also one would have to wait for the other to finish first.

Hi everyone. I have the following code:

Collider2D collider;
    [SerializeField] private LayerMask layer;
    // Start is called before the first frame update
    void Start()
    {
       
    }

    // Update is called once per frame
    void Update()
    {
        collider = Physics2D.OverlapCircle(transform.position, 0.5f, layer);

        if(collider != null)
        {
            Destroy(gameObject);
        }
    }

There's an object that moves to the object that should be destroyed, which is in the layer of the "layer" parameter of overlapCircle. When the object reaches the position of the object that should be destroyed, the object does not destroy, why is this happening and how do I fix it?
may be a beginner/general question but I post it here for lack of solutions in code-beginner and general

Get the inspector too

wispy terrace
#

And do another one with the target object selected

fathom eagle
wispy terrace
# fathom eagle

Wait, none of them get destroyed? or only one of them does?

In fact, I wouldn't use physics for a chess game unless you really want it xD

#

You could use this to get the distance between the two objects and destroy them once they are close enough

fathom eagle
wispy terrace
#

The problem is that, the first one that touches the other is the one thats going to get destroyed

#

And once it is destroyed, they cant destroy the other

fathom eagle
wispy terrace
#

I have no idea

#

I don't know if it even matters, they are both touching at the same time

#

I guess it has to do with the priority in execution of their scripts, which, idk how to check

#

In any case, if you want to keep the physics, add a bool that tells the script if that piece can destoy objects or not

fathom eagle
wispy terrace
#

And add it to the if statement for if the collider != nul

wispy terrace
#

They are technically both touching eachother at the same time

#

But unity's mind goes one thing at a time

. Hello does someone know how can be fixed "Memory leak" in this code, thx

Script creates texture from current obj's material and sends it to other obj's material ,
Can i somehow clean RAM garbage after 10-20 method calls? because when i change scene i suppose it clears ram somehow.
Every call takes up to 10mb ram, and speed of how fast method called doesn't matter, at about 100 call App runs out of ram and crash.

# 
    public GameObject Car_itself;
    public void Create_Texture() //  Creates Texture from one Material then Send it to Other Material
    {
        Material This_Object_mat = this.GetComponent<MeshRenderer>().sharedMaterial;
        This_Object_mat.SetColor("_Color", Random.ColorHSV(0, 1, 0, 0.6f, 0.5f, 1, 1, 1));  // This Object's Material

        RenderTexture buffer = new RenderTexture(
                         1024,
                         1024,
                         0,                           
                         RenderTextureFormat.ARGBFloat,  
                         RenderTextureReadWrite.sRGB 
                     );

        Texture2D texture = new Texture2D(1024, 1024, TextureFormat.RGBAFloat, false);
        Material material = GetComponent<MeshRenderer>().sharedMaterial;

        Graphics.Blit(null, buffer, material);
        RenderTexture.active = buffer; 
        Graphics.CopyTexture(buffer, texture);

        Material Target_Material = Car_itself.GetComponent<MeshRenderer>().sharedMaterial;  // Target Object's Material
        Target_Material.SetTexture("_MainTex", texture);
    }

You can call that manually, but you can expect there to be a stutter when you do because it's not cheap.

#

It would be better to manually destroy the textures you're using

#

Or better yet, reuse them. Unity has a built-in RenderTexture pool through RenderTexture.GetTemporary and RenderTexture.ReleaseTemporary

#

Also, I don't see why you need to create the Texture2D and copy to it. You can assign a RenderTexture as a material texture just fine.

vapid pawn

sage radish
#

You would have to destroy both the RenderTexture and Texture2D

#

And of course you would have to create the old textures, not the new ones you just created in the method

#

No reason not to use RenderTexture.GetTemporary here instead of creating one

#

And no reason not to just create the Texture2D once, assign it to the material once, and then copy to it whenever you need to update it.

vapid pawn
#

this with

Target_Material.SetTexture("_MainTex", RenderTexture);

instead

Target_Material.SetTexture("_MainTex", texture);

hello i can't understand , will this 2 codes have same impact on ram Memory

    Texture2D Huge_Texture;
    void create_SomeNumber()
    {
        Huge_Texture = new Texture2D(2048, 2048, TextureFormat.RGBAFloat, false);
    }
    private void OnDisable()
    {
        Resources.UnloadAsset(Huge_Texture);
    }

and

    void create_SomeNumber()
    {
        Texture2D Huge_Texture = new Texture2D(2048, 2048, TextureFormat.RGBAFloat, false);
    }

hello, i have a question. I did an elastic bed o Unity with this code, but the raycast always send me "No he dado a nada". The raycast dont hit the colliders

and will this "Huge_Texture" be unloaded /released from memory after methods is finished?

    void create_SomeNumber()
    {
        Texture2D Huge_Texture = new Texture2D(2048, 2048, TextureFormat.RGBAFloat, false);
    }
sage radish
#

Resources.UnloadAsset only works with assets saved on disk, not objects created at runtime.

vapid pawn
sage radish
#

Yes

#

Assuming create_Huge_Texture() is only called once before OnDisable

vapid pawn
#

yes 1 time,

thx ,i'll try now all advices you told

        StandingObjectPos = StandingObject.transform.position;
        Vector3 LastStandingObjectRot = StandingObjectRot;
        StandingObjectRot = StandingObject.transform.eulerAngles;

        Distance = Quaternion.Angle(Quaternion.Euler(StandingObjectRot), Quaternion.Euler(LastStandingObjectRot));
        Vector3 RotChange = StandingObjectRot - LastStandingObjectRot;
        Vector3 PosChange = StandingObjectPos - LastStandingObjectPos;

        transform.position += PosChange;
        transform.RotateAround(StandingObject.transform.position, RotChange, Distance);```

I have a basic script here that checks the object the player is standing on's movement and rotation change since the last frame and changes the players position and relative rotation to match, similar to if the player was parented to it. It works fine for the positioning and mostly fine for the rotation, but there's 2 main issues. One is when any of the axi goes over 360 or below 0 the player snaps to an unexpected nearby position. Also, it matches normally when rotating the object around one axis, but moves oddly when multiple are changed. I'm guessing it's due to the distance being calculated wrong or the the rotations being compared wrong since they're Vector3s. Anyone know how I'd go about fixing this?

# sage radish Yes

and because i've send and assigned texture to other material, is it possible to release that sanded to material texture too. or i can just

    private void OnDisable()
    {
         Destroy(TARGET_Oject.GetComponent<MeshRenderer>().sharedMaterial);
    }
sage radish
#

But it removes the reference, so next time Resources.UnloadUnusedAssets is called, the texture will be destroyed.

vapid pawn
# sage radish But it removes the reference, so next time `Resources.UnloadUnusedAssets` is cal...

if this whole script and i do like this at "OnDisable()" will it be almost fully released from ram? thx again for help , been struggling for week, searching info

    public GameObject Car_itself;
    RenderTexture buffer;
    Texture2D texture;
    public void Create_Texture() //  Creates Texture from one Material then Send it to Other Material
    {
        Material This_Object_mat = this.GetComponent<MeshRenderer>().sharedMaterial;
        This_Object_mat.SetColor("_Color", Random.ColorHSV(0, 1, 0, 0.6f, 0.5f, 1, 1, 1));  // This Object's Material

        buffer = new RenderTexture(
                         1024,
                         1024,
                         0,                           
                         RenderTextureFormat.ARGBFloat,  
                         RenderTextureReadWrite.sRGB 
                     );

        texture = new Texture2D(1024, 1024, TextureFormat.RGBAFloat, false);
        Material material = GetComponent<MeshRenderer>().sharedMaterial;

        Graphics.Blit(null, buffer, material);
        RenderTexture.active = buffer;          
        Graphics.CopyTexture(buffer, texture);

        Material Target_Material = Car_itself.GetComponent<MeshRenderer>().sharedMaterial;  // Target Object's Material
        Target_Material.SetTexture("_MainTex", texture);
    }
    private void OnDisable()
    {
        buffer.Release();
        Destroy(buffer);
        Destroy(texture);
    }
#

and as second but expensive solution is Resources.UnloadUnusedAssets

#

and unfortunately a RenderTexture as a material texture doesn't work for some reason.it would be way faster and performant than Graphics.CopyTexture

sage radish
#

From the video you sent, it seemed like you were copying the texture a lot more than just once. Is that not the case anymore?

vapid pawn
#

if i have 10 prefabs, and setActive 1 by 1 , in total i will create 10 textures

#

so i need to clear previous one

sage radish
#

If you're only calling Create_Texture() once for each script instance, then this should work. It's not necessary to call RenderTexture.Release() before destroying it.

#

And I'm assuming the scripts are being disabled or destroyed at some point, not just accumulating until scene reload.

#

From the look of this code, you should be able to destroy the RenderTexture immediately after CopyTexture and not keep a reference to it.

#

But then, there's no reason why you shouldn't use RenderTexture.GetTemporary and RenderTexture.ReleaseTemporary instead.

#

It'll be faster because it means every script instance reuses the same instance, since they all use the same texture settings.

vapid pawn
#

i've read about RenderTexture.GetTemporary and there was said that it life only for 2-3 second is it right

sage radish
#

For a couple of frames, yeah. But you're only using for less than a millisecond, to call Blit on it and then copy the data off it into a Texture2D.

#

After the copy, there's no connection between the RenderTexture and the Texture2D, so since you're not using the RenderTexture anywhere else, it can be disposed.

vapid pawn
#

Can't see/understand where to put RenderTexture.GetTemporary 🫥

#

i'll search some info about it
