😦 tried to switch over to using a ObjectPool and after setting it all up first thing off the bat I get a stackoverflow exception

got it

queen adder
# teal viper Probably a recursion somewhere.

this worked SpriteRenderer renderer; renderer = GetComponent<SpriteRenderer>(); Vector3 topRight = renderer.transform.TransformPoint(renderer.sprite.bounds.max); float verticalInput = Input.GetAxis("Vertical"); transform.Translate(Vector3.up * verticalInput * _speed * Time.deltaTime); Vector2 camPos = cam.WorldToViewportPoint(topRight); if(camPos.y < 0.0) Debug.Log("I am below the camera's view."); if(1.0 < camPos.y) Debug.Log("I am above the camera's view.");

#

Ill just change it for the bottom one too

mint remnant
teal viper
#

Nor do I know the details of your pool implementation.

mint remnant
#

ok was about to paste the code, but I think I see the recursion now

devout flower
#

Is pooling one of those things that almost always boosts performance, just sometimes a negligible amount

teal viper
mint remnant
#

I'm trying it because in my case spawning up a new object was a heavy hit on memory each instantiation, a minecraft like chunk of blocks, so much data had to be new'd up for each

#

My basic ObjectPool setup

        chunkPool = new ObjectPool<GameObject>(
            () => { return Instantiate(chunkPrefab); }, // create
            (GameObject) => { GameObject.SetActive(true); }, // get
            (GameObject) => { GameObject.SetActive(false); }, // release
            (GameObject) => { Destroy(GameObject); }, // destroy
            false, // collection check
            10, // capacity
            50); // max capacity```
though I get no more errors now, it's not working right, so more reserach 🙂
devout flower
teal viper
# devout flower Yeah, basically

Well, if it's configured correctly, then there aren't cases like that.
If not configured correctly, your pool might be eating more memory than necessary.
Other than that, there are cases where the benefit is negligible.

devout flower
#

Got it 👍

summer stump
# devout flower Got it 👍

You are trading cpu time for memory allocation when you pool. Memory is almost always at less of a premium. Taking less time on the cpu is almost always good.

If that is not the case, there are probably other significant issues to be addressed

devout flower
#

Wait, do memory allocations get cleared during runtime at some point

#

Can someone direct me to an article about this stuff for unity

summer stump
summer stump
devout flower
#

Ah ok, garbage collector

toxic yacht
#

that or how it's decided to release objects back to the pool

mint remnant
#

this is going to be trickier than I thought, going to want to skip some steps in the startup code for a chunk, but some definately will need to occur since the data will be different per chunk. Mainly I wanted to stop the horrendos new calls each time

#

I guess I need to look into what SetActive(true) actually invokes, I blindly copied it from a video

toxic yacht
#

SetActive is the same as clicking the enable/disable toggle on a game object in the editor. It invokes OnDisable() and OnEnable(), and when a game object is disabled, none of its components or that object's children will run their update loops.

mint remnant
#

right now all my new up code and populate chunk is in Start(), guessing what I need to do is split that up and put the memory newing into a seperate method, and check if already newed up if so skip

worn stirrup
#

whats the issue?

mint remnant
#

missing a semicolon per the error and screenshot

#

and what is that line with public Rigidbody = rb; between hte class and it's brace...

worn stirrup
mint remnant
#

well you copied it wrong

teal viper
#

Might want to learn about the basic C# syntax so that you don't miss small things like that.

mint remnant
#

don't know why people want to learn 2 major things at once, C# and Unity both deserve their own time

toxic yacht
#

Usually I stick a Reset() method the class I'm pooling, and then call it in the Get wrapper for the pool:

public class ChunkManager
{
    private ObjectPool<Chunk> pool;
    
    public Chunk GetChunk(args)
    {
         var chunk = pool.Get();
         chunk.Reset(args);
         return chunk;
    }
}

read the bot message if you expect help

deep yew
rich adder
#

clearly not

#
  1. why are you using a specific number for vector3 and also why is not a variable, also its not written correctly hence the error
  2. why are you not using the clone/copy returned from instantiate to put it in array if that was the end goal
deep yew
#
  1. I tried to grab the position of the object that I wish to put it behind it but I've decided to do it manually.
  2. Huh?
rich adder
#

also you're passing a position as Object, the more i look at this the worse it gets tbh..

anyway read the docs i sent how to properly write Instantiate

You'll get more control with single script. Put all panels into a single array and move them together. If one reaches outer bounds swap it to new position.

#

Note you can also have just one tiled large sprite and just animate material offset to move it back and forth

i have a problem.

blue is the player, red is the AI, orange is the AI's line of fire, green is the direction the AI should go.

whenever the player gets on a place that is higher than the place the AI stands on, the AI's line of fire can be blocked by whatever the player is standing on and thus can hit them.

i want it to find the position it should move to in order to be able to target the player, but i dont know how to do that

Probably because nothing is assigned. You need an actual instance of an actual type that implements the interface assigned(via code, since there's no way to assign it via the inspector by default)..

# worthy tundra i have a problem. blue is the player, red is the AI, orange is the AI's line of...

Hey, this is an interesting problem you are presenting. Unfortunately, there isn't an easy solution to this using Unity's navigation system.

I think your best bet is to have pre-placed visibility markers for your AI so they can have points where you know they can see the platform. The process would be:

  • Get the closest visibility marker to the npc.
  • Raycast the marker to the player.
  • If hit, navigate to that marker position on the navmesh. If not hit, get the next closest visibility marker and repeat.

This will require placing visibility markers which will add to your level design time. However, a dynamic solution without markers would be a lot more complicated. I had an idea for that and I can go over it if you want, but I think the marker solution is a lot better.

Hopefully that makes sense, let me know if you have questions.

Mainly focusing on these two:

void OnJump(InputValue value)```
For OnMovement I plan to add a minSpeed + maxSpeed, a Dash and a RunSpeed.
For OnJump, I plan to give it gravity, a grounded function and a DoubleJump.
How do I add in the ``GravitySettings`` and ``GroundSettings`` to   ``void OnJump(InputValue value)``?

so gamers, whats the best way to do racing ai? making a mario kart clone and just thinking about all of the drifting and turns makes me think of using a bunch of colliders to tell the ai what to do, but that is really cumbersome especially if i have a lot of maps

eager spindle
#

it would be more convenient if you built your track with a spline. have your cars follow the spline with an offset

#

to get very technical, mario kart rigs their races a lot such that

  • players who are first at the start of the race fall behind a lot
  • players in the middle of the race are given equal opportunity to catch up
  • last places tend to receive better boosts and racing AI becomes much more difficult
#

but I don't think you're thinking of that here. As long as you get the car to follow the spline it should be fine

tender wharf
#

i'm just thinking about having a basic racing ai that could potentially use the drift functionally so that i pass the class

#

Unity is really fun and easy but its so damn time consuming

opal zealot
tender wharf
#

especially when it comes to finding assets ;_;

#

but thanks for the valuable info gamer, I'll look into splines

eager spindle
#

nintendo rigs all their party games. mario party especially, theres a set of narratives that play out every game. including first place players getting screwed over at the last minute, last place players suddenly making comebacks

these are small things that make mario party and mario kart much more memorable than something that's just randomly generated, yet consumers dont know about

raw robin

Hi all, Im running into a bit of an annoying logical issue hoping if someone can help:

I have a player with grid based movement. There is two item, Item A and Item B.

When player step on an Item, it picks it up, follows the player.

And when the player with an Item, steps onto Item B, it switches to holding onto item B.

Now I don't want the item to switch indefinitely (since both Item A and Item B are on the same tile as the player, and the colliders/triggers are activating in Update)

My solution is, once I dropped the Item, it will only be "pickup-able / turn on collider" after the player has moved 1 tile

The issue is, if I want to make the player to be able to "throw" the item in an direction, how should I handle the colider? As I want the item to stop if it hits any obstacle. I "need to" turn off the collider when I first throw the object because I don't want it to instantly pick it back up.

Question: Is the way Im handling the collision good? Have you seen a better way? Thanks

sleek gazelle
raw robin
#

hmm interesting, make sense, technically I can have two colliders and set them on different layers but on the same object

dense plume
#

Are these triggers or colliders?

#

If they're actual colliders, Physics.IgnoreCollision is what you want

#

Turn off the collision between the player and the item while it is being held, re-enable the collision after it is thrown. Make sense?

tender wharf
eager spindle
#

that works

#

though the car wont exactly follow the road smoothly

#

make sure the cars are offset from each other so they dont go to the exact same spot

#

when it comes to balancing also dont make every car take the tightest corner otherwise your players cant overtake them

is there a way to mkae a variable show in the inspector but read-only?

Can I spawn a canvas according to the players position even if it is UI related?

#

for example I want to show the inventory next to the player

frosty hound
#

If it's a world space canvas, it has a world position. So yes.

#

If it's screenspace, then you can't move the canvas. You can however move the elements (for example, the inventory panel) and position it with code to be where you want relative to the player.

ionic zephyr
#

Ok, so I should make it a world space canvas then

It's trying to instantiate whatever is in the Prefab field. Not sure why indexes would have anything to do with it?

So, it should instantiate cat, but it's not

yes but where is it

show the field

sweet sierra
#

I have made it a property

rich adder
#

if its a property how did you add the Prefab to it

sweet sierra
#

This function does the job

image.png
#

It's on the same gameObject

#

By default, it loads character at index 0

keen dew
#

It's clearly trying to instantiate before it sets the property value since it prints the error before the name

rich adder
#

You must be running the previous method before this function runs

sweet sierra
#

But I have RequiredComponentEnabled 😬. Lemme try placing UpdateCharacter code in Awake(); and instantiation in Start(); of the other script

rich adder
sweet sierra
rich adder
#

RequiredComponent just simply slaps the Component onto the object if its missing

sweet sierra
#

Now to fix the position and rotation of the character 😂. But at least it's working.

rich adder
#

it has nothing to do with order of methods

sweet sierra
#

So this is perfect that it waits until char manager is awake, then does this

rich adder
sweet sierra
#

I've read that but yk... kinda dum dum of me to assume that both of them should be in Start

rocky canyon
#

just a bit

rich adder
#

there is no guarantee which Start will run first unless you mess with Order of Execution

Awake <-- Set up self
Start <-- Grab stuff from others

I think it goes by the ID but not too positive

We're 4 group members. 2 artists, 2 coders.

Another programmer does the UI and linking it to the code-behind.

But right now, setting the animations is a really big deal 💀

Time to hack the NavMeshAgent and create a Rigidbody Agent 😈 wish me luck

Even harder is gonna be making the character face the right way because the prefabs that the artist sent come with preset positions.

animations are a pain

sweet sierra
#

Any idea on how I can change the predefined position in a prefab without tearing it apart. It has metarig, etc. in it

if u mean the pose not really.

if u mean the orientation (can use an empty gameobject)

are they not T-Pose?

Hi friends.. Just starting with unity again after some months.. still getting grasp of things again.. my old game when I open the code i see colors on things.. but in the new game when I write the code everything looks same color.. how to fix that?

eternal falconBOT
sweet sierra
rich adder
#

seems they are all facing Z / Forward which is quite normal as default

rocky canyon
#

simplest atleast

sweet sierra
#

Hmm.. so get a reference to the spawned child then rotate in script is best I should do?

rich adder
#

no no reference needed

rocky canyon
#

no..

#

just rotate the child (object) so its facing the parents Z direction

#

well the left direction

rich adder
#

right click the object, Create Empty parent rotate to the left.
Now rotate the child as desired to match parent

rocky canyon
#

w/e orientation u want lol

sweet sierra
#

Yes but the character spawns at runtime. And it's different for each character ig.

rich adder
#

you have to make a prefab, dont spawn in model directly

#

if they all have the same orientation you can keep the parent the same and just swap out the child accordingly

sweet sierra
#

omg yes. I still have a lot to learn 🤦. But yes I got it now

rocky canyon
#

you'd spawn the parent the root obj

#

the graphics will spawn b/c its a child

sweet sierra
#

Model to prefab, then fix orientation, then assign prefab to database. Will do the job

#

Thanks a lot y'all! Really appreciate it as a beginner 🥹🙌

image.png
#

There are no compile error and the file name is the same as the class

rich adder
#

they just define contract for the implementing class/struct (methods, props, events)

#

values are provided by the classes or structs that implement the interface

rocky canyon
#

show us PlayerBullet.cs

solemn fractal
rich adder
rocky canyon
#

nope, no errors there

rich adder
#

I get that too sometimes when I create a new script on a gameobjec/prefab

#

unity just fucking up in this case

rocky canyon
solemn fractal
#

Ok thank you !!

rich adder
rocky canyon
solemn fractal
rocky canyon
#

is it selected as the external code editor in the settings?

rich adder
#

also yeah check if its External Tools

#

might need to Regen project files a couple of times

solemn fractal
#

Will check that, thank you!!

solemn fractal
rocky canyon
#

via hte package manager

solemn fractal
#

yeah been 6 months without using unity.. might be it

rich adder
#

yeah do you have Unity and DevKit extensions ?

rocky canyon
solemn fractal
#

I should have.. if I open the scripts from my old game I get no error just in this new one I created now

rocky canyon
#

its 2.0.22 now.. and they dont use the Code Editor one anymore

rich adder
#

also make sure to remove the Visual Studio Code Editor package just to avoid any weird hooking problem

rocky canyon
#

its deprecated

solemn fractal
#

I see, ok thank you

rocky canyon
#

one day, they'll make it all plug-n-play 😅

Got the character to spawn perfectly in position. The only thing remaining is the character animation setup. What's the best way for this though?

because now my character is spawning at runtime so I don't think I can just assign like that, or can I?

# rich adder wdym best way ?

Nevermind. Lemme simply the question. if I assign the controller directly to the prefab, it won't arise issues for me right?

sweet sierra
rich adder
rocky canyon
sweet sierra
rocky canyon
#

mmhmm shoould work as is

rich adder
#

either way it would actually

sweet sierra
#

Can I ask just 1 more question for now? I might be sounding annoying but... this is the last step to completion lol

rich adder
sweet sierra
#

Alright so... I need to access the character but... the character is...

image.png
#

this far

image.png
#

So, I should assign the "Character" now? Right?

#

And then access the child through it

solemn fractal
sweet sierra
#

Ignore the question at this point 😭 answered it myself

rich adder
#

thats why the Type Mistmatch usually

sweet sierra
#

Obviously. In this case, I just wanted to access the animator

#

So, I got a reference to the "Character" (spawner), then used GetComponentInChildren<Animator>(); and got it to work

rocky canyon
#

make sure u cache those types of variables and re-use the cached versions

#

dont know ur code.. but jsut dont call GetComponent every frame for example

#

via Awake() or Start() but im sure u know that

sweet sierra
#

Me?

rocky canyon
#

yesh u

sweet sierra
#

Yes I do that in Start() or Awake() 😂

rocky canyon
#

some ppl go crazy w/ the getcomponents

#

putting them in update and stuff 🫣

sweet sierra
rocky canyon
#

ignorance

rich adder
#

You can also access it as a property from Character(if it has a script with animator referenced) and skip the get component completely 💪

sweet sierra
#

That's like:

"What's your name?"

"XYZ"

"Okay. What's your name?"

#

🤦💀

rocky canyon
#

lmfao!

rocky canyon
rich adder
#

to be fair I did that too in the beginning lmfao

slender nymph
# rocky canyon putting them in update and stuff 🫣

fun fact, but while caching the result of GetComponent is definitely advised, the actual GetComponent call is very fast so it isn't really worth worrying about all that much unless someone is really going overboard

rocky canyon
#

ohh cool! lol

#

🤫 i'll keep it a secret

new toys! sweet

rocky canyon
#

the more i learn unity the more i feel gaslit.. alot of the things i heard "NEVER DO THAT!" are more like.. "its okay if you do that a little bit"

#

it all started with, Camera.main

slender nymph
#

I mean, most things are okay in moderation. Like a single Find call in Awake? that's technically perfectly fine even though it's going to be slower than almost any other way to get a reference to another object. It's still better to teach people to do it the right way though

slender nymph
sweet sierra
#

Honestly, I spent 1 and a half month trying to learn unity back in Decemeber 2023. And even for a month in July 2023. And I hated it. I thought it was sooooo complex.

But now, in a month's time, I'm learning and enjoying it, never thought I would 🌝. Internship coming in handy ig

rocky canyon
#

ya, im not complaining by no-means..

#

i guess its better to know the most proper way

#

and ignore the techanically okay types

rocky canyon
sweet sierra
#

But again, I knew 0 coding in July 2023. And beginner coding in December 2023.

#

So I guess it plays a huge role too. Building blocks and then connecting them through logic.

#

Currently, I'm an intermediate or more C++ developer (2nd semester of Bachelor's just ended) but yeah... I wanna be a few steps ahead of my colleagues 😉

rocky canyon
#

humble 💪 flex

rocky canyon
#

would this be the cause for this API change?

image.png image.png
#

only namespace im using is AI (Unity6) project

image.png
slender nymph
#

yeah, probably

rocky canyon
#

linearVelocity ftw

#

yup, that was it ☑️ , was gonna go old school w/ the rigidbody stuff

slender nymph
#

could always use some preprocessor directives if you want to maintain compatibility with older versions. or you could disable the warning for that line 🤷‍♂️
i'm fairly sure that velocity still works, it just internally uses linearVelocity

sweet sierra
#

Aren't VS and Rider the most preferred and optimized for Unity?

rocky canyon
sweet sierra
#

That's a relief to know. Because I actually researched on this (didn't wanna leave VSCode) and learned that it is possible to code Unity with extensions and stuff.

#

So I simply went for VS after that

rocky canyon
sweet sierra
#

That's nice to know 🫡

#

Question : I have an animation flow like this:

Idle state -> Hold state

When ball is thrown, repeat

image.png
#

But obviously using time to do this is unreliable. And Animation Events are being soooo tricky for the prefab. What do I do to get the same result as I am getting right now?

wintry quarry
#

not sure what you mean by animation events being tricky for a prefab.

surreal scroll
#

if i get a script component from a prefab that contains a bool can i use it in another script?

wintry quarry
surreal scroll
#

in the second script i used GetComponent but i can't seem to use the bool

#

from the first script

wintry quarry
#

i can't seem to use the bool
This is very vague

# wintry quarry Animation events or StateMachineBehaviours are the way to go

Yes I added an event but you could guide me on this please?

So basically, the event controller is on my character.

But I need different scripts (one on ball and one on balls spawner) to call the animations. And event demands a function from the scripts attached to the same gameObject. So, how exactly can I achieve this?

surreal scroll
#

thank you very much i'm sorry

wintry quarry
#

Have that function call a function elsewhere, however you need.

surreal scroll
wintry quarry
surreal scroll
#

i can't use the bool in ScoreScript

wintry quarry
#

Why not

#

what happens when you try

surreal scroll
#

i don't know

wintry quarry
#

what did you try

#

YOu don't know what happens?

#

Something is happening that made you come here

#
  1. You tried something
  2. Something bad happened
  3. You came here
surreal scroll
#

nothing is happening that's the problem

wintry quarry
#

Tell us about 1 and 2

surreal scroll
#

i'm very new to programming

sweet sierra
rich adder
#

start with that

surreal scroll
#

i don't have any errors

wintry quarry
rich adder
#

check the code/ function is even running

#

put Debug.Log inside methods, start debugging

surreal scroll
#

o tried to put if (PlayerScript.IsAlive == true) AddScore();

wintry quarry
#

this is the 1.

#

the thing you tried

surreal scroll
#

yes

wintry quarry
#

So this is wrong because you used the class name instead of your actual reference variable

#

you need to use your reference variable

# 
if (player.IsAlive) AddScore();```
rich adder
surreal scroll
#

i was being hasty my bad

#

if (PlayerScript.IsAlive == true) { logic.AddScore(); }

#

that's what i meant to send

#

i'm very

#

sorry

wintry quarry
surreal scroll
#

OH THANK YOU SO MUCH

wintry quarry
#

And what you have would still give you errors

#

so when you said you had no errors... that wasn't helpful

surreal scroll
#

i'm stupid

rich adder
#

yeah you probably weren't looking at correct spot

surreal scroll
#

i forgot i removed the code when it didn't work

rich adder
#

or your IDE is not underlining you have a bigger issue (don't code without configured IDE)

surreal scroll
#

sorry

#

thank you very much tho

#

i have one more question

rich adder
surreal scroll
#

i don't understand

#

do you mean the red line

rich adder
#

the underline red ?

#

yes

surreal scroll
#

yes it was there

rich adder
#

oh ok well, you saying no errors was misleading lol

#

moving on.. whats your new question?

surreal scroll
#

i forgot i removed the faulty code

#

i added a tag to a prefab that makes it so when you touch it you die but the copies of the prefab don't have it

rich adder
#

make sure you applied the new changes to all the prefabs

surreal scroll
#

ok i'll check thank you

rich adder
#

if you drag a prefab inside the hirerchy it becomes an Instance, anything changed there wont affect other prefabs unless you apply the "overrides"

surreal scroll
#

thank you so much it works

#

now my game is complete 😎

#

after i dragged the new prefab into the spawner it always stops after spawning two prefabs

#

even tho i set the function to spawn a new prefab into void update

#

maybe this has to do with the fact they all have the same tag?

i don't have any errors i double checked and i didn't change any code after it was working

no code that has to do with the spawning at least

wintry quarry

#

this is a extremely dumb question but
private void blahblahblah : blah
^^
what's that bit called? if forgot:(

wintry quarry
#

My guess is you are not using a prefab, but rather an object in the scene, and once it gets destroyed your Instantiate code no longer works. When this happens an error will go in the console

rocky canyon
#

& are you spawning a prefab.. or a copy of something in the scene?

surreal scroll
wintry quarry
rocky canyon
#

once it gets destroyed (off the side of hte screen) or w/e it doesn't have a reference to anything ot copy anymore

rich adder
#

have a feeling they dragged in the prefab from the hierarchy

It's a just a type - a class which blahblahblah is extending, or an interface which blahblahblah is implementing

these are not

where do you find the project folder i mean

Windows > General

#

how did u make a prefab w/o knowing where the project window is?

surreal scroll
#

i dragged an asset to the hierarchy then i added some children

#

and then i dragged it back into the assets i think

#

and it created a prefab

rocky canyon

where do u think ur dragging assets from?

surreal scroll

idk

#

the bottom

"the bottom"

those tabs have labels

rocky canyon

oh u mean the PROJECT folder

my bad

rocky canyon

no worries..

#

just trying to drive it into ur memory 😄

rich adder
surreal scroll
#

why is there a problem if i drag it in from the hierarchy but not if it's from the project folder

rocky canyon
#

b/c thats not techanically a prefab..

#

its a Instance of the prefab..

rich adder
rocky canyon
#

^ its a copy

rich adder
#

a copy

rocky canyon
#

ur copying a copy

surreal scroll
#

ok thanks

#

it still doesn't work

rocky canyon
#

but what was happening was.. the copy of the pipes u slotted into the slot.. got destroyed..

#

and then the script couldnt spawn it anymore

#

prefabs from within the project folder dont get destroyed.. (jsut their copies do)

rich adder
surreal scroll
#

it doesn't stop spawning but the tag isn't getting copied

rocky canyon
#

b/c u changed the tag on the COPY

#

not the actual prefab

#

same problem

surreal scroll
#

OHH

rocky canyon
#

double click the real prefab

#

and change that

rich adder
#

thats why i told you to apply the tag in the Overrides

surreal scroll
#

maybe i should think more

rich adder
#

or just click the link I sent..

#

actually learn how Unity engine itself works

surreal scroll
#

ok

#

thank you guys very much for the help

rocky canyon
#

crash course

#

Tank -> drag in scene -> now its an instance (if i modify THAT instance) it doesn't matter..
BUT if i APPLY the overloads (now the prefab matches the version i changed)

#

you can also just double click the prefab.. and it opens in (prefab view)

surreal scroll
#

i changed the prefab itself this time by clicking it in the project folder and the selecting the tag

rocky canyon
#

that will change all versions (even the ones u already have in the scene)

surreal scroll
#

i'll keep all this in mind next time

Any recommendations on an easy to use asset to build out game settings? I need something to read and change settings such a resolution, turning shadows on/off, texture resolution etc. I can do the UI for it, and even saving/loading from a file.

rich adder

#

If you're willing to do the UI and I/O, you're already tackling the majority of the work :P

primal trench
#

should i upgrade c# from 9 to 12? i tried to do some array stuff but it said it isn't avaibled in 9

slender nymph
#

doing so would require you messing with roslyn and it isn't generally advised because it isn't something that is actually supported by unity

#

i'm guessing you tried to use the new collection expression syntax, but you should just use the older collection initializer syntax

primal trench
slender nymph
#

yes that is the new collection expression syntax

primal trench
#

what's the old?

slender nymph
#

until c#12 that is not how you intialize an array

frosty wren
frosty wren
slender nymph
#

each of those options usually only takes one or two lines of code to change

eternal needle
frosty wren
#

Thanks, will give it a try. Just thought there would be some well polished tools out there for something every game probably needs

slender nymph
#

there are plenty of assets on the asset store that have settings menus built in, you could search for those. but if you want to build the UI yourself, then it's literally just a matter of reading the documentation to find out what line of code you need to run for each setting change

Hi, I'm working on a turn-based strategy game and I am working on a system where the player can bring a battle into focus (they will click on a button and the battle will open in a less interrupted window). For now what I've been doing was that I just disabled all the other tiles that weren't a part of the battle and spawned a fog of war. This was pretty performance heavy (a 1-2 second load in debug). I want to transition to a system where I would load a scene and the battle would only happen in that specific scene (and data would be shared through scriptable objects) and then when the player closes the battle, the original scene would be loaded back in. Imagine a 4X game like civ, scene loading is pretty heavy unless the scene would remain in memory, is this possible?

rocky canyon
#

additive scene loading sounds like something that might help

#

keep the main scene loaded in memory.. and add/remove the battle scene as needed

i looked through these errors already

slender nymph
#

if you have absolutely confirmed that none of the many errors you are receiving are in the callstack for this code, then you are likely just looking at the wrong object

#

but also, fix your errors.

toxic frigate
#

im fairly certain im looking at the right object

slender nymph
#

"fairly certain" is not "100% certain because you've verified"

toxic frigate
#

ive shift selected all of the objects which have that script and it still looks like this

#

change the log from Start to this: Debug.Log($"{GetType().Name}.Start has been called on {name} ({GetInstanceID()})", this); and show what it prints, then also click the log to see what it highlights and show the inspector for that object

there is clearly something you aren't showing then. share the entire class using a bin site

ty

slender nymph

#

certain, but let me double check again

slender nymph
#

while you check, move that log to the end of the Start method too instead of the beginning

toxic frigate
#

nothing is modifying those fields, i had just changed those to public anyways since i wanted to see if the values were assigned or not

slender nymph
#

you can serialize a field using the [SerializeField] attribute if you want a non-public field to appear in the inspector

#

but now that you've moved the log to the end of the Start method, is it still printing?

gameObject is already short enough to get from the Component you're on , assigning a variable to it is double the work

frank flare
#

why is main doing issues?

image.png image.png
rich adder
#

you probably are looking for the Camera component not Gameobject

frank flare
#

they're different?

rich adder
#

very different

#

Camera is a component, GameObject contains components basically

#

you can do Camera.main since its static

#

or if you're super micro optimizing or have no Camera with a Main Camera label, you can just do
[SerializeField] private Camera cam

#

then link that and use cam.ScreenToWhatever

#

not necessary though as Camera.main already has its own opimizations (so i've heard)

frank flare
#

idk what serializefield does

rich adder
#

just makes a private field serialized in the inspector

#

like when you do public it shows up in the inpsector

wdym "download"? this doesn't "download" anything, in fact it doesn't do anything at all, which is the point of the error

this is like if you just wrote a line that was 3; that line doesn't do anything. it's just the number 3 on its own

how can I make

always be center of the screen?

at that point you don't need to be using ScreenPointToRay at all, just raycast from the camera's position in its forward direction

like it has Input.mousePosition

can you give like a real life scenario or like your current scenario so I know wtf you're talking about

late burrow
#

though when i think of that i probably could do custom class where i already did that loop beforehand toss all variables there and then foreach it in every function i need

slender nymph
#

or just write a method that does what you need and call the method while passing whatever data you need into it. but until you provide a real example of what you are trying to solve all anyone could possibly provide is speculation at best

late burrow

ok so for example

#

car has multiple of parts which each can hold multiple modules

and i want to add same variable to all of the modules at once

while skipping the looping part

why, depending on where I'm looking, the grenade never goes off in the same way ?

public void ThrowGrenade()
    {
        GrenadeInstance.transform.SetParent(null);
        Rigidbody rb = GrenadeInstance.GetComponent<Rigidbody>();
        if (rb != null)
        {
            rb.isKinematic = false;

            Vector3 localForward = RightHand.forward;
            Vector3 localRight = RightHand.right;

            Quaternion throwRotation = Quaternion.Euler(throwAngles);
            Vector3 throwDirection = throwRotation * localForward;
            rb.AddForce(throwDirection * ThrowPower, ForceMode.VelocityChange);
        }
        
    }
#

also if I remove throwRotation the grenade it's not going straight but at least it always go in the same direction

rich adder

could also be the wrong directon/rotation.
Debug them Gizmos class will be your best friend

the sprite editor lets you edit the pivots, otherwise use a sperate gameobject parent

eternal needle

long jacinth
eternal needle
# warm raptor why ?

because you want it to throw based on the direction the player is looking + some offset. syncing it up to throw with the hands local directions is just gonna be more of a pain, although i dont see anything super wrong with the current code. Maybe throwAngles is wrong or this code is playing at different points in the animation causing it to read different values

#

try to visualize even with Debug.DrawRay to see what these directions are

click it, and switch it to Pivot

it now works i think

if its still wrong, after that use the Sprite Editor to edit the pivot

Do you have an EventSystem in your scene? 🎯

so you are trying to interact with world canvas how exactly? fpv or wat

that checks if "W" is down

and if it is

change a variable

but w isn't triggering

how did you check the code is running ?

it works when not a worldspace, only breaks when it is worldspace

are you using a FPV controller ?

also what does "w" have to do with world canvas

like clicking "w"

thats probably why

your cursor is locked and not visible most likely

world canvas doesn't like that

replace the one on the Event System

do you have an event system object in your setup? if so can you screenshot the gameobject

thats the old input module or new?

use that method instead then

Where does GetComponent()'s overhead come from?

Is it just managed/unmanaged interop shtuff? Outside of that, all I can conceive the components collection to be is just something like a type-keyed dictionary, and lookups there should be cheap, no? 🤔

Quite possibly.

A common practice to have a script initialize itself in Awake() (cache references to it's own components and such), and anything requiring interaction with other objects/scripts happens in Start()

For object pooling is it better to store objects in a list or an queue?

mint remnant
rocky canyon
#

(keeping a list of the last few seconds to average them into a rolling value)

#

but, i've also had that question.. would a list be better?

#

i dont think i can test w/ the accuracy to know which ones better

mint remnant
#

Also are you talking about the actual pool? And if so, are you rolling your own or using Unity's. If Unity's you don't care how the objects are stored in the pool. If rolling your own that's a tough one. But once you get them out of the pool what you store them in is going to depend more on how they will be used from there.
