Click the mouse button when hovering over one, and move the mouse without letting go of the mouse button, until your mouse is over the variable you want to assign it to, then and only then, releasing the mouse button

How do i make an infinitely moving sprite effect, where it infinitely moves in a direction? I have a sprite renderer with a Tiled Sprite.

https://gdl.space/xinipihabe.cpp this is mainmenu this one gamemangerhttps://gdl.space/\ so what im trying to do is when player hit play start new game dont load save file start spawn player that it everthing lock etc. the other thing im trying to do is when the player hit save save player postion and where the camera is so i quit the game gull i can comback hit load game get the json file

@deft grail @steep rose i posted it

#

i used that link that you guys gave me

slender nymph
#

you certainly did, you even used that exact link as your gamemanager code

steep rose
#

Dont ping me randomly dude

glass totem
#

ok

slender nymph
#

you still need to fix your link

glass totem
#

i fixed it

slender nymph
#

you most certainly did not

summer stump
#

Just put the link in. No fancy formatting

steep rose
#

I believe dani himself made a tutorial about weapon sway as well

glass totem
slender nymph
#

and have you confirmed that the code is running and that the objects being assigned are the ones you expect?

glass totem
#

yes

#

everthing is hooked up to where they should be

#

it sayin in debug player posting is saved game is save but when i hit load it loads me back to start and not to where player postion was or anthing

slender nymph
#

wait, is this happening when you like return to the main menu then go back into the game scene? or is it happening when you've closed the game and relaunched it?

glass totem
#

happening when you've closed the game and relaunched it

#

but when i open the game up agin then hit load i get loaded back to where i started

#

and not across the hallway

slender nymph
#

and you have confirmed that it loads the data and has assigned everything correctly after loading the data?

glass totem
#

yes

slender nymph
#

prove it

glass totem
#

how

slender nymph
#

show how you verified that

#

you said you confirmed it, how did you confirm that? because i don't believe that you did and i can see at least one reason why you did not in this code

glass totem
#

i was using prefs edior

slender nymph
#

how did you confirm that the data was correctly loaded and the fields/properties are being assigned correctly? that part has nothing to do with looking at the save data

glass totem
#

then i would not know then

slender nymph
#

so then the answer to "have you confirmed that the code is running and that the objects being assigned are the ones you expect" is "no, i have not confirmed that, i have only confirmed that the data is saved i have done nothing at all to ensure it was loaded and applied correctly"

#

here's a fun fact: that GameManager object will not exist until the scene it is in is loaded

#

don't ignore the errors in your console

glass totem
#

but there are none

#

that what im saying

slender nymph
#

screenshot your entire editor window with the console window open when this issue is happening

glass totem
slender nymph
#

do you have your player, vcams, and gamemanager all in the main menu? 🤔

glass totem
#

oh yeah idk if you wanted it to

#

also in game

slender nymph
#

are those the same exact objects that are in your game scene, or are they perhaps different instances of those objects? keep in mind they would need to be DDOL to be the same objects

glass totem
#

give me a sec

#

this is all my button hooked up to for the game

slender nymph
#

so you aren't setting the player's position, you're changing the position on the prefab which won't affect the instance already in the game scene. and as you can see from your own warning log and that last screenshot (which is really the only one out of all of these i needed), you don't have the vcam you were trying to assign in this main menu so naturally that cannot be assigned as well

#

you need to load the data after you've loaded the correct scene and assign to the objects that are in that scene

glass totem
#

oh so get rid of all clearshot from the code and change the positon to set and save player postin on save and load

#

instead of the other one

slender nymph
#

you already are trying to set the player's position on load, but you aren't doing it to the right object because the object you want to affect is in another scene

#

just like all those vcams i assume

glass totem
#

yes

slender nymph
#

and the reason starting a new game works is because you likely have the gamemanager with the correct references set up in your other scene and you destroy the one from the main menu when you start a new game

glass totem
#

yes

#

soo how would i fix it then pikachuface

obsidian granite
#

I'm making a game that has a system that checks if placing something in a certain position would collide with the eventual predicted path of the player. Currently, I'm instantiating an object, using Physics2D.BoxCast with the predicted path of the player, and then destroying the object. The issue with this is one of memory. I have no clue how Unity handles memory internally, but if I'm calling DestroyImmediate() on the objects, why isn't the memory immediately deallocated? I'm 90% sure it's due to the objects since the only other thing that would be using memory is just variables and structs, all of which should be WELL under a megabyte. I can't use VS memory viewer since it just... doesn't work for some reason

mint remnant
#

Garbage Collector is an independant system that handles memory cleanup. THere are ways to force it to clean up, but not sure if you have control over that in Unity

#

You can see the calls in the profiler btw, called something like GC.Alloc and possibly the clean up too, I forget

steel stirrup
#

Why are you creating and destroying objects instead of just recycling them?

mint remnant
#

THat ^^ switch to object pooling if it's a real issue

#

Basically the garbage collector IS a giant pool of objects, where the objects are sized memory chunks

obsidian granite
#

everything's happening all in one frame

#

so i think it had something to do with moving objects not being registered by physics until the next update or smth

#

idk

steel stirrup
#

It doesn't matter, and also this is going to be either fundamentally flawed design or very premature optimization

obsidian granite
steel stirrup
eternal needle
#

the part about "I'm instantiating an object, using Physics2D.BoxCast" doesnt really make sense. you dont need to create an object to use physics functions on
also ideally you shouldnt be using it for pathfinding like that

obsidian granite
mint remnant
#

something smells wrong if you're using 12gb up lol

obsidian granite
#

if it is, that means it would be in the way of the path, and i need to not spawn the object there

obsidian granite
#

i wanted to use the memory thing in vs debugging tools but it just doesn't work

#

give me c++ and allow me to manage memory myself 😔

steel stirrup
obsidian granite
#

wait actually i don't think it gets up to 12 gb anymore, that was in a worse version of the code. it gets to around ~ 5 gb and then hell breaks loose because i'm using a recursive algorithm (i'm GOING to make it iterative eventually, trust)

#

stack overflow and such

steel stirrup
#

you obviously have a memory leak somewhere

obsidian granite
steel stirrup
#

Just post the code

obsidian granite
#

it's a bit

mint remnant
#

how many objects are we talking about here?

obsidian granite
#

idk how this server works but usually people don't like long code blocks

#

all the relevant code is pretty long though

summer stump
eternal falconBOT
summer stump
#

Use paste sites

steel stirrup
#

Also stop using DestroyImmediate before you accidentally kill a prefab

#

there's zero reason you should need it for this

#

or Destroy in general

obsidian granite
#

if i only ever destroy instantiated objects

steel stirrup
#

Yes, I know that's how you're using it now

#

just don't use it at all

polar acorn
obsidian granite
#

that's all the relevant code

eternal needle
#

DestroyImmediate can only destroy assets if u use the 2nd param, but u should be using Destroy anyways

obsidian granite
#

i just haven't changed it back

steel stirrup
#

needing to free the memory at all is the issue

obsidian granite
#

i thought it was coming from objects' memory not being deallocated after their destruction

steel stirrup
#

Even if it was

#

How are you possibly creating enough to use up 12gb?

#

like put that into context

#

you are using more than most computers had a few years back purely for a boxcast

eternal needle
#

use the profiler, deep profiler will quickly point you to the line causing issues

obsidian granite
#

i have NO CLUE

mint remnant
#

For starters, learn to refactor code to methods that perform a single task, see SOLID principles

obsidian granite
#

how 30 mb were being used

#

it can't be from structs and variables because... well, it just doesn't make sense

#

so i thought it must be from the objects being instantiated

obsidian granite
#

it's not getting 12 gb anymore, it gets to ~5 and then it overflows (probably just due to the amount of recursion). stack size is 1 mb, which means that my structs and variables are the things going over that 1 mb limit. therefore, the other 4.999 GB has to be stuff on the heap. i'm not doing anything with the heap besides instantiating gameobjects

#

so it has to be that, right?

summer stump
obsidian granite
#

ah okay so

#

everything happens in one frame

#

meaning that unity hard lags

#

like i can't do anything in unity until the generation is done

#

won't that affect my ability to use the profiler?

eternal needle
#

the profiler will tell you why its lagging in the first place

#

you staring at the ram in task manager wont do anything

obsidian granite
#

i'll successfully generate a level and i'll look at what's taking so much ram

mint remnant
#

for (int j = 0; j < bounceInfo.Count; j++)
{
GameObject currentPeg = Instantiate(obstacle, bounceInfo[j].pegPosition, Quaternion.identity);

THat looks scary, physics can cause lots of bounces you might not even see

obsidian granite
#

i destroy it

#

like 4 lines down

#

what that section of code does is generates pegs where it believes it is going to need to, and then checks if those pegs would interfere with the bounce it currently wants to do. if it does, then it'll change the direction of the bounce

mint remnant
#

have you ever used Extract Method in VS?

eternal needle
#

just use the profiler

obsidian granite
#

idk how to jump to a specific frame

mint remnant
#

When you see a big spike, click on it, it will pause the game and you can scroll it it

obsidian granite
#

oh wait i'm dumb as hell, profiler only captures like 300 frames

#

i need to pause quicker

#

alright cool i got the spike

#

what am i looking for?

mint remnant
#

look in the timeline section, change it to heirarchy and see what's causing it

#

or make it full screen and post a pic of it here for more tips

obsidian granite
#

oh my LORD i have to comb through the entire call stack

#

it's like 1000 calls deep

mint remnant
#

have a little recursion going on???

#

that would certainly explain 12 gb

obsidian granite
#

i have explicitly stated this

#

it is a recursive algorithm

#

it should still not be using 30 mb of memory per call

#

whether or not it's recursive or iterative, it's 30 mbs every time the code is being ran. i need to know why

mint remnant
#

well for debugging purposes, I'd put a clamp on hte depth of your recursion to maybe like 5

obsidian granite
#

oookay well now I'M stumped because the profiler is saying it's not even allocating that much memory

#

only like 120 mb, which is about what i'd expect

#

like for the 137 call deep recursion

#

wait does printing stuff use a lot of memory?

mint remnant
#

you might wanna rethink your design if your doing a 130 recursion deep call

obsidian granite
polar acorn
#

It isn't free, but it's more CPU intensive than RAM intensive

obsidian granite
#

it will become iterative

#

i know how to mate it iterative

#

i'm trying to figure out this issue first

polar acorn
#

Still, if you're trying to profile, you should disable prints

obsidian granite
#

okay so just doing nothing besides using a midi player thing, unity's taking 2.5 gb ram. so the "5 gb" it's been taking is really more like another 2.5, but i'll see what it is without prints rq

eternal needle
#

there is also the memory profiler if you want a deeper look specifically

steel stirrup
#

The amount of ram unity is using in task manager has very little to do with your game's performance

#

I'm doing nothing and just staring at the package manager and still use ~10gb

obsidian granite
#

what??

#

10 gb doing nothing?

steel stirrup
#

Sure, unity isn't exactly lightweight

#

Rider is using another 6 lol

obsidian granite
#

like that's more than a lot of systems have to offer

steel stirrup
#

It doesn't really matter, the game itself barely uses any

steel stirrup
obsidian granite
#

i'm not talking about the build

#

i'm talking like... just being able to open the editor

#

10 gb doing nothing?

steel stirrup
#

Still doing better than firefox probably

obsidian granite
#

is rider worth it?

#

i've been meaning to buy it but i don't do anything with c# outside of unity

#

not my language of choice

steel stirrup
#

It's just an ide

#

I've never used VS, so not really sure what the differences there are

obsidian granite
#

yeah but why would you pay for it when other ides are available?

steel stirrup
#

it's cheap enough to not care

#

and ive used it forever, so why switch now

obsidian granite
#

anywho, i'm gonna look at the unity memory profiler ig

obsidian granite
#

it was the printing

#

that's what the memory leak was

#

lord have mercy

#

😭

#

i guess maybe it was all piling into a queue since it was all happening in one frame?

#

everything runs 100% fine now

errant flower
eternal needle
# obsidian granite it was the printing

printing will always be relatively slow, but now that i look at the code you have a bunch of string concatenations. string stuff always produces lots of garbage

I've added a 0 Friction Material2D to the boxcollider, I set the Rigidbody2D to Interpolate.
Still my player Square (placeholder) is jittering as I walk on the Floor in the game. Why is that?
I've seperated the input and physics as one should, I dont get it.

make sure to keep animated UI on a separate canvas to avoid redrawing the entire canvas as it will only redraw for UI that are constantly updated . . .

I don't get why the entire canvas would be recomputed every frame. Surely just the transformation matrix of the object being affected and its descendants?

how?

you can disable the component (used for input/controls), or set a bool (on the component) to false when dead. you only receive input when the bool is true . . .

there's nothing wrong with making a public field

#

and just assigning it in the inspector

summer stump

obsidian granite
#

oh it's a prefab? then you can't reference an existing object via the inspector

round mirage
#

but i have put reference for a script ```if (cinematicTuyauEvent.PlacePotion)
{
Destroy(gameObject);
}

}
}```
obsidian granite
#

yeah so then assigning it in start is your best bet

round mirage

#

wait why is the prefab's code running?

#

before it's been instantiated

round mirage
#

no its when its instanciate

obsidian granite
#

oh alright

obsidian granite

#

When you instantiate the prefab, pass the reference then

obsidian granite
#

make sure that the gameobject you're referencing with .Find actually has that component

#

var newThing = Instantiate(prefab)

newThing.variableToAssign = reference;

#

There is never a reason to use find

#

ohhhhh ty

#

.Find is pretty slow and awful so it should be a last-resort thing. i use it because i'm lazy

There are the tag and type varieties if you really need

sorry, i was away. you placed the isDead check in Update for the input but you handle the movement in FixedUpdate. HandleAnimation will still use the Xinput if it wasn't 0 before the player dies. if this is true, then HandleMovement will apply velocity to the rigidbody. i'd move the isDead check to FixedUpdate instead. This will block all movement . . .

The IDE will help with those though, once you start using the correct characters

native seal
#

what would be the best way to get a float within a given range and round to the nearest decimal. For example, if the range is 1.3-1.6, I want equal outcomes of 1.3, 1.4, 1.5, and 1.6. If the range is 1.75-2, i want equal outcomes of 1.76,1.77, etc all the way to 2

#

is this able to be done generically ?

rich adder
#

something something math.pow

wintry quarry
#

So you may wish to do things with integers. E.g. an int which represents the number of one-hundredths

native seal
#

so multiply by 10, 100, 1000, etc first?

#

how would I check how many decimal places the number has?

#

without using strings preferably

brave compass
#

The decimal type is more appropriate if you want to store fractions in base 10.

native seal
#

perhaps something like this?

#

or will i get floating point issues

rich adder
# native seal perhaps something like this?

Would this work?

 private decimal minValue = 1.3m;
 private decimal maxValue = 1.6m;
 public int decimalPlaces = 2;
...
 decimal randomValue = (decimal)Random.Range((float)minValue, (float)maxValue);
 var roundedVal = decimal.Round(randomValue, decimalPlaces);
 Debug.Log($"Rounded{randomValue} random number: {roundedVal} ");```
slender nymph
#

don't even need to use decimal for this, unity has the Snapping.Snap method that can be used for floats

rich adder
#

TIL

slender nymph
#

of course that would still be affected by floating point inaccuracy though

rich adder
#

this is kewl

 var randomValue = Random.Range(minValue, maxValue);
 var roundedVal = Snapping.Snap(randomValue, stepSize);
 Debug.Log($"{randomValue} Snapped random number: " + roundedVal);```

I would use Radianscs int maxPlayers = 6; float radius = 200f; float angleIncrement = 360f / maxPlayers; for (int i = 0; i < maxPlayers; i++) { var angle = i * angleIncrement; var angleRadians = angle * Mathf.Deg2Rad; var xPos = Mathf.Cos(angleRadians) * radius; var yPos = Mathf.Sin(angleRadians) * radius; var player = Instantiate(playerPrefab, transform); player.localPosition = new Vector2(xPos, yPos); }

wintry quarry
#

Since Sin and Cos are looking for input in radians

frigid quartz
#

Ahh thank you guys, the video I was watching about sine and consines was using degrees. Thanks!

slender nymph
#

also this makes no difference since you happen to be doing a division that works with ints, but you are doing integer division with 360 / 6 so it results in an int not a float

frigid quartz
frigid quartz
slender nymph
#

if you want the result to be a float then at least one of the numbers in the operation must be a float. otherwise it's an integer that gets implicitly cast to float. so 1 / 10 would be 0 instead of 0.1

frigid quartz
#

Hi all,

Another brainfart moment from Spud.

if (isRotating == true)
{
    float currentMouseLateralPosition = Input.mousePosition.x;
    float mouseLateralMovement = currentMouseLateralPosition - startMouseLateralPosition;
    cameraLateralRotation.Rotate(Vector3.up, -mouseLateralMovement * orbitSpeed * Time.deltaTime);

    float currentMouseVerticalPosition = Input.mousePosition.y;
    float mouseVerticalMovement = currentMouseVerticalPosition - startMouseVerticalPosition;
    cameraVerticalRotation.Rotate(Vector3.right, -mouseVerticalMovement * orbitSpeed * Time.deltaTime);

    startMouseLateralPosition = currentMouseLateralPosition;
    startMouseVerticalPosition = currentMouseVerticalPosition;
}

I have this 'orbit camera' code that works great, but I can't for the life of me remember how to clamp the Vertical rotation of the cameraVerticalRotation Transform. 😕

looking at your code though:

}
else if (hit.collider.gameObject != gameObject)
{
    this.gameObject.transform.position = hit.point;
}

unless lockOnPosition is set to null (which only happens if something other than an ICanBeDamaged object enters the trigger) the position of that object cannot follow the mouse

hybrid gust
#

Whoops, yeah I suppose that's true

#

I've been meaning to fix that

#

guess now is the time

slender nymph
#

also you might want to consider using a physics query instead of relying on trigger messages, that way you won't end up with the issue of OnTriggerExit being called for only one of multiple objects in the trigger

hybrid gust
slender nymph
#

like an OverlapSphere, SphereCast, etc

hybrid gust
slender nymph
#

instead of having a sphere collider that you stick to the object when it gets detected, you instead use the physics query to check the area around where your mouse is (keep the current raycast from the mouse position and just use the query at its hit position)

Who said not to use tutorials? You shouldnt be blindly copy pasting them and ideally stay away from the ones that are "build a whole game in 5 minutes!". Look up specific concepts, then build your system. Example: how to build a shop system is gonna get you an exact tutorial thatll be hard to extend upon for what you need. You'll be better off just taking the part where they look at an item to know how to "buy" it

I would assume that for digital things to touch they would have to overlap... like, otherwise, touching vs overlapping would be a matter of floating point rounding errors, right?

how to apply force for a certain amount of time

deft grail
terse spindle
#

like in the mobile games you hit an obstacle you go back a bit then stop

slender nymph
#

for that a simple impulse force would be all you need rather than applying force over time

#

also don't multiply your forces by deltaTime, ForceMode.Force already takes that into consideration and you must be applying constant forces in FixedUpdate rather than Update

cosmic dagger

#

originally this was for keeping the player running

#

#

or wdym by "faster"

polar acorn
slender nymph
#

and make sure you aren't doing something silly like completely overriding the velocity of the RB somewhere

        yield return new WaitForSeconds(2);
        plrmovement.enabled = true;

  }


  void OnCollisionEnter(Collision coll){

    if(coll.collider.tag == "Obstacle"){

        Debug.Log("We Hit" + coll.collider.name);
        plrmovement.enabled = false;
        StartCoroutine(MovementAfterForce());

terse spindle
#

so I dont need two updates

raw token
# terse spindle why do I need to remove it what does it do

Time.deltaTime is the time since the last frame (or physics update, depending on where it's used) in seconds. So it's useful to figure out a distance from a velocity, for example - you multiply the velocity by the amount of time which has passed.

But it doesn't make sense to multiply an instantaneous force by a time. You want all of the force now - no reason to scale it down

steep rose
#

Remove deltatime, its arbitrary when in fixedupdate

Never ever use deltaTime in AddForce

Multiplying it by deltaTime (a tiny decimal) will of course reduce the force a lot. So when you remove it, you have to decrease the force

terse spindle
#

I saw something that update is working every frame so more fps I got , more speed I got

#

delta time is making it

summer stump
#

AddForce ALREADY has deltaTime in its force internally

terse spindle
#

eh how can I say

summer stump
#

Never ever ever ever use deltaTime in AddForce

terse spindle

# terse spindle

if this is just to move it continuously, then do not use ForceMode.Impulse for this, ForceMode.Force would be more appropriate. Impulse is for an impulse of force, or one-off forces that should apply all of the force all at once

summer stump
#

Also, why are you using Impulse -ah too slow

terse spindle

I dont know bro just trying different things

terse spindle
terse spindle

pretty sure it running every frame is not what he wants, and impulse is what he wants
but who knows 🤷‍♂️

so I dont use deltaTime in fixedupdate

Impulse in the OnCollision message made sense 👍

let me try

#

ah

terse spindle
#

one for continusly moving forward

#

one for

backing off

summer stump
terse spindle
#

so I use for impulse for back off

deft grail
#

thought you just added a variable since it had the same value and you pointed that out

terse spindle
#

and dont use impulse for continuesly

summer stump
#

You can certainly use deltaTime in FixedUpdate (it will convert to fixedDeltaTime though)

terse spindle
# 
 void FixedUpdate(){
        rb.AddForce(0,0,forwardForce,ForceMode.Force);
    }
#

so Like that huh??
?

slender nymph
# terse spindle backing off

for your impulse to knock it back, you will also want to reset the velocity to 0 immediately before the knockback

terse spindle
#

am i right

slender nymph
#

right, since your knockback force is similar to the amount of forward force the object will already be affected by if you don't reset the velocity before the knockback at best it might be knocked back only a little bit

terse spindle
#

so how do I set velocity 0

#

rb.velocity?

#

the guy said

#

rb.velocity = vector3.zero

deft grail
terse spindle
#

I try and its good

#

but Im not sure if the player is always in same speed

#

how can I know that

I feel like its getting more speedy every second without hitting an obstacle

Debug.Log(rb.velocity);

if the rigidbody does not have drag or any other forces acting on it, then yes you are constantly accelerating

terse spindle

angular drag of 0.05

That will work against angular velocity, but not linear velocity

terse spindle

its getting speedier every second

Add some Drag

The running force will eventually reach an equilibrium with the drag force, effectively resulting in a top speed

hello i have a question regarding two scripts that i've written, one script takes a mouse input and info from a raycast and the other script takes this info and decides wether or not to deactivate itself, the code works fine, but when i duplicated the game object that would destroy itself and tested the code, both the og and the duplicated object were destroyed when interacted with. i basically need them to destroy when interacted with separately rather than both with one interaction. Could anybody help? id rather dm the code so its a bit quieter

raw token
# terse spindle it worked but I didnt understand how it did

You're accelerating your character by applying a force. The drag force is applied to your character in the direction opposite of their current velocity.

Drag force is calculated as a function of the magnitude of the character's velocity and the Drag value you set as a multiplier. So as the character moves faster, a greater drag force is applied against them. When the character is moving fast enough, the drag force will become large enough that it's equal to the force you are applying to move it - the two forces cancel each other out, so the character just maintains it's current velocity instead of accelerating.

When your Drag was set to 0, it totally disabled the drag force, so there was no resistance to the acceleration.

the issue is that when i duplicate the gameobject with the second script, when the first script interacts with the gameobject via the raycast both objects get destroyed

if that makes sense, i just need a way of indavidualising each gameobject somewhere in the script i think, but i cant think of anything

It's kind of hard for random YouTube videos to target their entire audience's skill level as it varies so widely. So some sort of foundational knowledge from more structured content is definitely useful before wandering out into the wilderness. But an introductory 10 hour video may offer that sort of structure 🤷.

I kind of followed the Learn content and challenged myself to integrate stuff I was learning about in my projects through other avenues along the way, which worked well for me, but I can't say if it would work well for everyone

That makes sense - all of the smudges will check every frame if wipe.spraying, and blow themselves up if so.

A more common solution to interacting with specific instances like that is to have whatever's performing the raycast try and get the "second script" component from whatever it hit, and if found, call a method on it. That way whatever functionality needs to happen is only executing on the relevant instance (and you don't have a bunch of objects constantly checking if they should do something 😁)

You could, totally!

But often times and definitely for more complex scenarios, it doesn't make sense to have all that logic relevant to those objects contained in the class which is raycasting. So instead the raycaster just calls a method on what it hit. This way, the class on the object which was hit is still responsible for all of it's own logic and behaviors - the raycaster just kicks things off

#

Although in this case, a wiper destroying smudges does sound totally reasonable 🤔

really good course, honestly I dropped it like 2 thirds in after I learned what I needed to start my own game, afterwards I just try to make something with the info I know, end up messing up, so I either look up a tutorial, documentation or ask here if nothing else works. I recommend digesting the information and then applying it by yourself to your own ideas

tardy plaza
#

i wrote another script that works fine for a vaccum, it works off of collision detection. I was hoping there would be a way to physically check if a raycast was touching a collider, by checking the tag, layer or name of what was outputting the ray and perform a method off of that is there ANY way to actually do this

deft grail

but could the object being hit by the raycast check where the raycast was coming from?

#

The spraying script should call a public method on the smudge script to let it know to destroy itself. At least that's what I assume you want

also, in OnDeath you set currentlyAlive = false then check if it's false in the next line. it will always be false because you just assigned it, so they if check is unnecessary. the same applies to if (isDead == true). you just assigned it to true right above, so it will always be true . . .

More specifically, I want to find a struct, based on only one of its elements being matched

raw token
# waxen adder How do I use find on a list of structs? Getting confused by online resources

I had never considered it before... If no match is found, Find() would still return a struct with every member set to the default value for its' type...

From what I'm reading, it sort of sounds like you'd need to test your conditions against Find()'s return value to see if it really found a match or not, which seems cumbersome.

One nice sounding alternative is to use FindIndex() instead (since it has a more definitive return value) and then just get the matching struct by that index, if it exists

charred spoke
#

Or you know just loop over the list and test the condition yourself.

#

If match break; simple as

In my struct, I have an object, so it would be null as default iirc

willow scroll
#

I have always used First (FirstOrDefault) & Select

I'm the opposite lol

Though that's because I've been deep in unrealscript, where doing this whole find process is surprisingly easier and gives you the index in the list instead

raw token
# waxen adder What do you think of something like this? ``` GridNode result = gridNodes.Find(n...

Should work... kind of a bummer to allocate another struct each time though. You might just store the predicate somewhere and reuse it on the result (if this is happening really frequently, anyway - one extra allocation won't matter much otherwise).

But I'm pretty sure Find() is more expensive than a simple loop, what with all the call stack cycling and such.

I sort of feel like maintaining a separate index on the gridPos member might be worthwhile, if you do find this to be a performance bottleneck at some point.

waxen adder
#

Hmmm. Sounds like I might run a loop after all lol.

I guess this is all happening at start, and shouldn't really be happening afterwards, so whatever performance hit this gets only really happens once

charred spoke
waxen adder
#

I do, but I imagine that's a misconception at this point

charred spoke
#

If performance is an issue you could always implement your search as a parallel job

#

It is O(n) right now so performance really depends on the size and given how stupid fast cpu’s are I doubt you will see an issue

waxen adder
#

I agree, even more so since this is most likely only going to be happening in a "loading" phase

#

Could turn this list of structs into a dictionary too potentially

charred spoke
#

How would that help ?

keen dew
#

All this is premature micro-optimizing. Surely you have more pressing issues to spend your time with

waxen adder
charred spoke
#

The lookup of the list is also constant

#

Like list[5] will not be slower than accessing a dictionary with a key

#

Actually the index 5 here is the key

#

In a way ofc

waxen adder
#

Right, but in my situation, I wouldn't know the index. I would know the key though

charred spoke
#

What would be the key ?

waxen adder
charred spoke
#

That would still loop over the key values until it finds one

#

Not faster than looping the list

waxen adder

eternal needle
#

I too dont even see how a dictionary would work here. You have vectors only, what value are you trying to associate it with

#

The answer is simple: profile it and see that it runs literally instantly anyways with a list.

#

If the list doesnt have 10k elements in it, dont worry about the speed

Even if does have 10k elements 🤣

I would worry for 100k to begin with
