#

can't a component that's on the same object as the trigger still receive the message?

#

maybe i am mis-remembering

unreal phoenix
#

My favourite part of Unreal is the ability to add infinite colliders to even just one Object and just manually set up the subscriptions when the Object is made

polar acorn
#

GetComponentInParent also works if you call it on the object with the component on it

verbal dome
swift crag
#

yeah, give it a look real quick

#

i need to stop "giving things a look" in my actual projects

#

i keep finding random crap in my scripts

#

ah, int wtf = 123;, hello there

vale blade
#

git stash :)

swift crag
#

hmm true

#

git stash my work, do the thing, hard reset and reapply stash

#

I prefer to just have a few projects in different editor versions and render pipelines

#

but I cleaned all of those up recently

unreal phoenix
#

Can confirm what Osmal said is true

swift crag
#

Good to know.

#

well, also bad to know, because that makes things harder!

verbal dome
#

Also im just 99% sure thats how it is

swift crag
#

yeah, that should really be clearly documented

#

given how fundamental that is

unreal phoenix
#

The object with the collider will not recieve messages if the parent has a RB

verbal dome
unreal phoenix
#

weird

#

Unity colliders have always annoyed me

swift crag
#

i wouldn't think it would be hard to add that

#

Anything that moves away from messages, with their nitpicky names and occasional lack of specificity, would be a win in my book

vale blade
#

well I showed you how in that SO post :p

#

you just get a unityevent for what to do when the trigger occurs so you can link that up to any custom event system too

solemn fractal
#

is there a way to check in the method update, if something collided? I mean i want the experience on the floor to move toward the player. But for it to move, the move method needs to be inside the update. So what I need is like inside the update method something saying. IF the object collided, move.

#

becuase if I do that inside the on collision tigger the method is called 1 time and I need it to be called every frame to keep moving

slender nymph
#

Use a physics query like a Raycast or CheckBox

solemn fractal
#

hmm never used both.

buoyant knot
#

You should use Raycast/Cast/BoxCast/OverlapCollliders/etc if you want to know what is colliding in the middle of a normal evaluation.

#

You should use OnCollisionEnter/Exit/etc if you want a method to be called only when you enter/exit/stay in collision with something.

#

OnCollision methods let a script know what to do AFTER a collision happened. Casts let you move things while respecting collisions at any time.

solemn fractal
#

hmm ok ..got it

junior seal
#

How do I detect if a player enters an area? I put a box collider in the area that I want to be detected and it istrigger. Im having trouble code wise because im trying to access the colliders script from a gamemanager script and i dont think im doing it correctly.

verbal dome
#

Put a OnTriggerEnter on the area/box collider object

junior seal
#

Because the gamemanager has a whole lot more information

verbal dome
#

The method has a parameter for what collider entered it

junior seal
#

My Game Manager

{
    public static GameManager instance;
    public GameObject player; //test

    int enemiesRemaining;

    //door stuff - Dami

Hey guys I have a prob here, cant understand why.. it was working and now its not.. and I am confused. I have this message. but in the code I have like this

junior seal

My Collider```public class FinishLine : MonoBehaviour
{
public bool isInBox;

void OnTriggerStay(Collider other)
{
    if (other.CompareTag("Player"))
    {
        isInBox = true;
    }
}
void OnTriggerExit(Collider other)
{
    if (other.CompareTag("Player"))
    {
        isInBox = false;
    }
}

}```

#

already have it

short hazel
#

Then you have another script attached somewhere else, that doesn't have it

#

Like below the Circle collider here

solemn fractal
#

oh no

#

i didnt see it.. might have dragged

#

byt mistake.. damn I am so tired like 10h straigh in unity + work

#

I think i am going insane

#

need a rest hahah thank you !

summer stump
junior seal
#

what do you mean?

summer stump
junior seal
#

the boolean

summer stump
#

What is the goal of this? To call YouWin?

short hazel
#

"Tell me you copy-pasted the code without telling me you copy-pasted the code"

junior seal
summer stump
short hazel
#

GameManager has a singleton setup. It has a static field you can access anywhere that will refer to the one GameManager in the scene, use it

junior seal
#

the boolean in finish line. I need to check if it is true, bc if it is, i need the things in ExitDoorCondition to happen

summer stump
#

Don't check the boolean

junior seal
junior seal

Sorry im not totally familiar with this. I literally just learned what this was like 4 days ago

#

okay cool. thanks

#

Is there a way to tell Unity when to compile ur code rather then on each time u save a file

swift crag
#

You can set the editor to not automatically reload

#

preferences -> asset pipeline -> auto refresh

#

It will recompile when you hit ctrl-R, or when you create/move/delete a script asset

#

I guess that, more pedantically, this just means it doesn't look for changes to files until you hit ctrl-R

#

if you create a new script asset in unity, it sees the change immediately

short hazel
#

And then there's CompilationPipeline.RequestScriptCompilation() method if you want to trigger a compilation via code, like with an editor window or context menu

queen adder
#

Oh both methods are pretty cool!

#

Thank u this is gonna be a huge time saver

solemn fractal
#

hey guys.. why that doesnt work? the game object with this script always go towards the player.. even if I dont move with the player .. this object goes inside the player to its center, but even tho they have same position .. the object is not deleted

wintry quarry
queen adder
#

Yeah lol^^

wintry quarry
#

Also why are you checking the same condition twice?

solemn fractal
#

so if its unlikely how do I do that check? is there a way to say, if u are 1cm from the player delete?

queen adder
#

I just dont like having to compile alot because compile times in Unity are pretty slow compared to Godot or unreal IMO

wintry quarry
#

check within a certain threshold, yes

solemn fractal
wintry quarry
#

Vector3.Distance(a, b) will give you the distance

#

then you can check that it's within some small amount

solemn fractal
summer stump
solemn fractal
#

ah.. he said vector3.distance

#

so i thought that was a vector3

summer stump
#

No, the type on the left

#

Did you look at the error?

#

Or the docs for Distance?

solemn fractal
#

yeah

#

so need to set as a float

#

ok

#

thank you

wintry quarry
#

it's just a number

short hazel
#

"I cannot put a float into a variable of type Vector3" would be a more user-friendly message

swift crag
#

When you try to use a variable of type Foo in a place that wants a Bar, C# will try to convert it.

#

Since you did not explicitly ask for a conversion, this is an implicit conversion

wintry quarry
swift crag
#

If this is impossible, you get an error.

#

You will get a different kind of error if you try to perform a cast (an explicit conversion) between two incompatible types.

#

Sometimes an explicit conversion is legal, but an implicit one is not

solemn fractal
#

now its working.. thank you

swift crag
#

e.g. float explicitly, but not implicitly, casts to int

solemn fractal
#

now i need to learn about this checkbox or raycast to use instead of ontrigger enter.

short hazel
swift crag
#

indeed

#

the thing i find funny is how int to float is implicit

#

even though, by definition, the number of floats that loses precision when they become an int is exactly equal to the number of ints that lose precision when they become a float

buoyant knot
#

doesn’t implicit just mean you don’t have to ask?

summer stump
#

No cast required

buoyant knot
#

that’s what I thought. making sure

Hi. I have been stuck on this problem for a bit now. Im trying to reference this playerInventory script in my script but it wont let me do it in any way.
public Inventory playerInventory; Player.cs

using UnityEngine;

public class Inventory
{
    public List<Weapon> ownedWeapons = new List<Weapon>();

    public void AddWeapon(Weapon weapon)
    {
        ownedWeapons.Add(weapon);
    }
}
``` *Inventory.cs*

Everything else will show but not inventory. Not even while debug mode turned on

Hey, guys! I have a question. I want to make in my game a functionality that when I click QuitButton to exit playmode and application, I want it to happen with a delay of 1 or 2 seconds. I was thinking to use IEnumerator in order to achieve that and also was thinking to use waitforseconds to do that. Can you please tell me which way is the best to make this functionality work?

ohhh I see, I did have it right, it just didn't register the syntax for the first argument as correct until I typed both

google is being inconclusive, something about the editor being open too long? a few people saying "nvm fixed" and not saying how

It's not anything related to your code, I'd say just restart the editor and see if it goes away

#

hey guys, how do I check on update for something that enter my collider if I cant use the ontrigger enter method as it call things 1 time. checked raycast and box something but cant understand how to do it. any help?

eternal needle
solemn fractal
#

oh

#

really ?

#

but actually.. what I want is more specific

eternal needle
#

then describe it more specifically, what are you trying to do if not be notified constantly about something inside the trigger

solemn fractal
#

So basically what I need is that I have a player.. when I kill a monster he drops exp on the floor.. and I want that when I get near the exp .. it will fly to me. But my player has a collider to check other stuff so I am using another empty object that follow player position with a trigger to check that collision with the exp

#

but the prob is that the script is on the object that will collide the empty one.. and I need to call the method MOVE on the exp script

#

but it needs to move only after entering the area of the trigger of the empty object

#

and that is it

#

this is the movement and it is working

#

now I just need to make that move be called when I enter

#

hi just wondering if anyone could help with my invoke? just wanting to delay the asked for request bt 2 seconds but in game it just says invoke couldnnt be called, thankyou

frosty hound
eternal needle
# solemn fractal

this isnt an empty object if there is a collider on the object, but regardless OnTriggerEnter you just check if the object has the script you are looking for. If it exists, then call Move and pass the transform in as a parameter

frosty hound
#

And you cannot use parameters

lusty socket
frosty hound
#

Because your function has parameters. In other words, you cannot use invoke for what you're doing.

lusty socket
frosty hound
#

A manual timer in update, or a coroutine.

lusty socket
frosty hound
#

Coroutine will work.

#

Manual time is tracking deltaTime in update by storing it into a float variable and checking if it has surpassed some value.

lusty socket
frosty hound
#

Your IDE should be throwing an error

lusty socket
#

This is the error i recieve using a coroutine in my code as shown above

ss24.png
frosty hound
#

Yes, because you're not passing anything to the coroutine and it's expecting it.

lusty socket
#

what should i pass through? this is how it was shown in the video just obviously with my additions in

frosty hound
#

Whatever you want message to be? Think for a second of what your function is actually doing.

lusty socket
#

showing a desription of the item

polar acorn
#

What value do you want message to be

lusty socket
#

is the value not the 2 for 2 seconds

polar acorn
frosty hound
#

Your functions purpose (assuming you actually know its purpose), is to display a message on a text component as a tooltip.

When you call that function, you have to give it the message to display as outlined by the functions parameters that you've made.

#

But I'm starting to realize this is likely a copy paste attempt at functionality with little to no knowledge of coding.

lusty socket
#

i watch videos to try learn what to do and add and use them to complete the actions i need, in this instance id have only known how to use a invoke but am in unknown territory here, the actual terminology behind alot of the code keywords kind of go over my head causing me to misunderstand alot which i apologise for, i usually just learn better being taught it first then figure out how to apply it into my own, as this is a little slip up i just need a little help with ive turned here for some help

frosty hound
#

This isn't about invoke or coroutines or how to make something happen after an amount of time, it's basic coding and understanding of functions.

#

You may want to do a tutorial on basic coding

lusty socket

#

parameters are the bools float etc i thought, am i wronh?

frosty hound
#

Wrong

polar acorn

#

SetAndShowToolTip(string message)

It's expecting you pass a string representing the message when you call the function.

lusty socket

lusty socket
#

so do i need to add my message i want to be displayed on screen in the brackets ?

#

for this to work

#

or am i way off

polar acorn

#

i have the message set up in a different script thats added to the items to give them each specifc item descriptions

polar acorn
lusty socket
#

but isnt my value different with each different item description?

polar acorn
lusty socket
#

in the brackets

polar acorn
#

What value do you want to pass to that function

lusty socket
#

the item desription

polar acorn
lusty socket
#

but thats different with every item because its in another script

#

so the value can differ depending on the item

polar acorn
#

So what item description do you want to show

lusty socket
#

one for each food i pick up

#

so 3 different item desriptions

#

not just 1 specific item desription

#

one with like the ingredients for pie when hovering over pie

polar acorn
lusty socket
#

one for cake ingredients

lusty socket
#

so i have the script youve seen

#

Yes this is the code I am looking at

lusty socket
#

it goes into the next sccript the setandshowtool

polar acorn
#

This is the same code that I have been looking at. What value do you want to display when this object is created

lusty socket
#

then when attaching this script to the desired item i can enter whatever message i wish in the inspector

I am watching this tutorial video where we create a script called "PlayerMovement"
and we also create a script called "PlayerCollision"
https://prnt.sc/0KhhmW7aj37L There is s "PlayerCollision" variable we wrote called "movement", in order to refer to the "PlayerMovement" script we wrote line 7.
But why do we have to we have to put "PlayerMovement in the empty slot in order for it to work, haven't we refered it in the script yet?

@polar acorn I'm sorry, but I still didn't figure out how to reference the FirstPersonController script. I don't know where it's Assembly definition is.

polar acorn

crystal cipher
#

this should say in units like "K" and "B"

#

for example. instead of 7,025 it shows in 7K

#

but when I debug Log it, it does work properly

#

but not the textbox

polar acorn
#

If your log displays that value then your text is being set to that. Are you sure the text you're looking at is the one this script is referencing and that it's not being set somewhere else

crystal cipher
#

umm.. no

#

playerprefs coins exsists

#

also

polar acorn
#

Why are you using find, and why are your variables of type game object. Just make a public variable for the text component and drag in the object you want directly

crystal cipher

oh

#

yo i have a collider in this 3 d game and it get turned on during animation and i have a code saying if acollison happens on this other object it get deleted but when i play the animation to swing the hammer down the object thats supposed to be deleted because of the contact does not get deleted what do i do?

Is there a unity function that gets called when an object gets SetActive(true); ?

#

is it OnEnable() ?

ok

Which GetMouseButton is it for XButton4?

#

i tried with index 4 but it doesnt work

#

maybe 6?

#

if 0 and 1 are Left click and right

why doesnt this work?

thats just so confusing then because its not null

gaunt ice
#

The text object should not be null, log them both

eternal needle
#

🪄 debug them both so you dont have to guess by looking at the inspector

You can just log them to see if they are null

trying to add a check so it doesn't destroy the enemy gameobject before detecting another collision from the projectile game object since with raycasting i ran into the issue where the enemy would destroy before the fake projectile would reach it

image.png 📎 Enemy.cs 📎 PlayerController.cs 📎 Projectile.cs
#

have not been able to figure it out

unique violet
#

How can I cache a current object and all of its children then when I want to revert everything back to that state?

hardy fjord
#

the note at the top of enemy cs can be ignored i forgot to remove that

gaunt ice
#

If you want to “revert” some objects back to some state, you need undo function, not just caching

unique violet
#

if there isnt a simple way to do it thats fine

#

ill just work my code for it

gaunt ice
#

I remember unity provides some undo function you may search it

eternal needle
# unique violet well the problem is im changing a lot continuously

could just use version control for this if its a lot of changes. Create some branch, work on that branch, if it doesnt work then just go back to the main branch without merging. If you want to keep some small changes along the way, then commit those and undo the others

#

otherwise you would be looking at making a custom editor script to store everything, which could work but its more effort for something that may be buggy

hello

how do I create a simple first person controller?

green copper
#

how can I make a prefab have a constructor with an optional argument? i want to have the option of inputting a size for an object, but if no argument is given, have a default value

#

and will it work with Instantiate()?

eternal needle
#

or adjust it after instantiate, depends what object you are adjusting

green copper
#

Making an asteroids clone for a project, was planning on

asteroidBreakFunction
{
makeTwoClones(0.5 current size)
destroy(self)
}

#

or alternately

asteroidBreakFunction
{
makeClone(0.5 * current_size)
makeClone(0.5 * current_size)
destroy(self)
}

#

pseudocode, I know the syntax is wrong

#

just planning

eternal needle
green copper
#

Ohhhhh right, I forgot that instantiate leaves a variable to play with behind

whats the difference between transform.SetParent(parent) and transform.parent=parent

#

they one and the same or is one more stable etc?

summer stump
#

Oh, yep
"This method is the same as the parent property"

versed light
#

ah okay thanks

green copper
#

the objects made by this function are disabled, along with all the components

#

I double checked and even remade the prefab, it's not prefabbing a disabled object

young warren
# green copper

Just to be sure, show the inspector of the asteriodPrefab object?

green copper
young warren
#

And the clones are disabled? Not just invisible?

green copper
#

the object, the collider, and the breaker script

young warren
#

Fracture doesn't have any code that disables this?

#

Or any code anywhere that disables this asteroid?

green copper
#

Fracture was leftover code, removed with no consequence

#

and I'm just starting on any asteroid handling code of any kind, nothing should touch it

young warren
#

Can you test by making a brand new prefab which is just a plain cube, no scripts, no tag, and set that as asteriodPrefab for now?

#

Unless asteroidPrefab is not GameObject

green copper
#

like this?

#

the cubes still exist

young warren
#

Does the asteroid have a tag?

green copper
#

yes, it has the tag 'asteroid'

#

it needs that for the laser collision detection code

young warren
#

If you untag it, use your original prefab, see what happens

#

I'm just trying to figure out possibilities here. Thanks for your patience and cooperation so far

green copper
#

and thank you for yours

#

okay

#

strange thing

#

did the first part

#

I mean, second

#

okay let me start over

#

I replaced the prefab with asteroid1 again

#

now the first set of children are enabled

#

the second generation are not

young warren
#

Are you using object pooling

green copper
#

this is sort of a recursive system, every time the asteroid is destroyed it's going to be replaced with two 50% scale clones until it hits a minimum

green copper
young warren
#

Show code where asteroid is destroyed?

#

And the replacing with clones part

green copper
#

this is attached to the projectile

#

this is attached to the asteroid

young warren
#

Okay, I'm going to suggest you ctrl+shift+f and search for SetActive

#

See if there's any that passes in false

green copper
#

new error message btw

#

no instances of SetActive with a false pass anywhere in files

young warren
#

Then it might be because of that error message, I'm not sure

#

Try to refactor your code to not spawn inside the OnDestroy

#

Sorry I'm out of ideas

green copper
#

thanks for trying

queen adder

Try to use ondisable

If I subscribe to an event when a scene loads and both the object that causes the event and the subscriber will both live the entire scene do I still need to unsubscribe? The reason for not wanting to do so is that I will need to add a reference to the event caller on the subscriber and that seems like unnecessary coupling

hey guys, if I have this setup here, where I have a prefab experience with an array of gameobjects, and I referenced inside that array 3 dif exp tpes. and inside the enemy when it dies I am saying drop(instantiate) the experience. But is there a way to tell which one?

image.png
pastel vector
cosmic dagger
solemn fractal
#

it wont allow me

cosmic dagger
solemn fractal
#

hmm.. so i need to create a method in ExperienceLevels, that is called when the enemy die in the enemy script

cosmic dagger
solemn fractal
#

and that will tell which one to spawn?

pastel vector
#

There is no way of unsubscribing without adding a refference to that object right?

cosmic dagger
solemn fractal
#

it is just very hard for me yet to think and choose which scripts to create and where to put things..

#

Its harded than coding it self. Sometimes I get lost for hours just trying to ifigure out where things will be

#

if I create a script only for exp.. or if I create 1 for the enemy and inside the enemy it will contain the experience logic etc

#

so hard to decide those things

#

also if I have 5 types of enemy.. dont know if I create 1 script and control all or should i create one for each.. or create 1 prefab for all and control it with other prefab

#

and things like that so hard to decide and understand

cosmic dagger
#

hmmm, you could unsub in the subscribed method, but only if the event is invoked before the GameObject is destroyed . . .

eternal needle
cosmic dagger
solemn fractal
cosmic dagger
cosmic dagger
# solemn fractal hmm.. and as a good practice or best way to do it. always when I have like 10 en...

if each enemy type has a group of experience they can provide, i'd use a ScriptableObject holding an array of the experience prefabs. if all enemies pool from the same group of experience prefabs, then using the SO works just fine. every enemy will point to the same SO in memory and randomly select from that pool

if a group or specific enemy uses a single experience prefab, place a check in the enemy script to avoid selecting from the array . . .

eternal needle
# solemn fractal also if I have 5 types of enemy.. dont know if I create 1 script and control all...

Each enemy will have similar behaviour right? Ex: regardless of who the enemy is, they may have an idle, moving, attacking mode.
Calling the functionality for these 3 examples should be done from 1 script, while the idle, walk, or attack functionality can differ between them. Like one may idle by standing around, one may wander, this functionality can be in another class and plugged into your enemy class

solemn fractal

Im trying to make a cube runner game for mobile but how do i make a working script so it works

#

looks like this now

lemme try it again

merry spade
#

how can i call a function as a prefab?

#

if the ore is being mined the "hp" of the ore should go down and if they hit zero the prefab calls a function that adds money

#

but i cant get a reference to the moneyscript

gaunt ice
#

are you trying make object in scene reference some script on the prefab?

minor viper
#

I made Exactly like the tutorial can anyone help me

Screenshot_62.png
keen dew
#

That's obviously not even close to what the tutorial shows

minor viper
#

i did like he did

keen dew
#

No you didn't

#

Link to the tutorial please

minor viper
languid spire
#

that is definitely one for @polar acorn

minor viper
#

He did like that but im trying and it dosent WORK

gaunt ice
#

so do you compare his code to your code?

keen dew
#

How do you suppose those are the same as what you have

minor viper
#

IDK IM NEW TO PROGRAMING

keen dew
#

New to reading too?

merry spade
#

i dont know how to get a reference

minor viper
#

no its just like everything he does when i try it dosent work

merry spade
#

the prefab should call a script function that is on the player

keen dew
#

Do it the same way and it'll work

minor viper
#

i cant cuz everytime i do it dosent work

#

bro try it yourself it to write the code exactly like that it wont work

keen dew
#

Why don't you try it yourself first

#

because the code you showed was just nonsense

#

do it the same way as the tutorial and then come back

minor viper
#

I REMADE IT LIKE 5 TIMES THE THINGS HE USEDOSENT POP UP OR IS ON MY KEYBOARD

#

Ok cool. If you can't follow a tutorial then there isn't much we can do for you

Are all errors resolved throughout all your scripts?

minor viper

think so

gaunt ice
#

do you save the script or there are any compile errors

modest dust

If there are any errors present then the code will obviously not compile

#

And the new version won't show up

#

New version being these fields that were meant to show up in your player controller script

minor viper

mabye works now

Just don't try forcing yourself into Unity without learning the basics (C#) first

ofc not defined, you have to create this function on your script first (and the field of type moneyscript)

yes ok

Hi guys, I have a problem. I'm using the latest unity 2022.3.11f1 and I have just started using Unity having not used it for some years and wanting to get back in it. I have noticed that whenever I create a Enum list , save it, let it do its magic in Unity, then look at the script with the Enum in there, the IDE will freeze and lag for about 10-20seconds before eventually becoming normal again. I don't know what is causing this and the enum is not exactly hugh... it can just be 1 item in the list and it will lag just from switching away from the script to another script and then back, and it freezes again. Any ideas on how to get this to stop doing this?

#

this is all the code that is in there at the moment, and this is causing IDE to freeze?

(i may be in the wrong room so let me know if i am.)
i am writing a enemy controller script and for some reason when the enemy touches the player #1 The player wont take damage, i know the damage and hp work as i have tested the hp earlier. #2 when the enemy touches the player it just rebounds and goes in a different direction randomly and i dont know why that is.
i can provide the scripts if you want to look at them.

teal viper
brisk escarp
#

alright give me one moment

azure zenith
#

member names cannot be the same as their enclosing type - What does this mean?

teal viper
#

The real question is why is it floating before the play mode.😅

azure zenith
toxic cloak
#

lol my bad it was the animation that came with the model that was messing my bad i figured it jeez

spark trail
# teal viper It's probably unity recompiling the assembly after code changes. You can disable...

I'm aware of the compiling after a change, that's fine, but unfortunately thisis beyond that. The other scripts that do not include Enums will save, and compile. (The bit I refered to earlier by magic Unity stuf) however, without any changes. If I then switch to another script from the tabs, then switch back to Enum without doing anything to either scripts, the editor freezes for about 10-20seconds. It's like having 1 FPS. You can see the cursor moving in the places you're clicking on within the script but its heavily delayed and takes about 10-20 seconds to fix itself. Unity itelf is doing nothing its just the IDE that seems to be doing something. ONLY when an ENum has been put into the code. If I delete the enum, I can switch all day everyday and it's instant, I can click on the script anywhere and type, and it's lag-free and instant. moment I put enum in there and save it, I can't type or do anything for about 10-20 seconds when I switch back to the script containing the enum.

not sure if I'm explaining this well

#

i have been working for 3 years with it and since yesterday, i'm forced to close it with task manager each time i change something

Hey guys. I create a scriptableobject to control my enemies most common stats etc... But now I have a doubt. to keep it simple, imagine i have 2 enemies. I have a spawn manager object and a script spawn manager. My question is. with 2 enemies I can have 2 prefabs.. but imagine I had 100 enemies, and all different from each other. Would i create 100 prefabs? or if not how can i create something that my spawnManager will be able to spawn all those 100 dif enemies? I cant have 100 prefabs right?

hexed terrace
#

You can do that with 1 prefab, but you would need 100 SO's with the different stats. When spawning you'd assign the SO to the spawned enemy.

#

hm. So i create 1 prefab called enemy. Ok. I assign the enemySO script there. But ok. I still dont get how I will be able to use instantiate and choose 1 from the other. Lets say. Instantiate(_enemy, transform.position, Quaternion.identity);

#

how here I say which enemy from 1prefab? i am still confused 😂

hexed terrace
# 
[SeriliazeField] private MyEnemyComponent _enemy; // assign prefab

MyEnemyComponent enemy = Instantiate(_enemy, transform.position, Quaternion.identity);
enemy.data = scriptableObjectList[index];```

@teal viper do you know how to disable visuals "Running low background priority tasks" ?

#

It seems this is casuing the lag

solemn fractal

#

What I gave you is obviously pseudo code, the list is where you need it to be.. probably the spawn manager..

solemn fractal
#

so this list should be of which type?

Hello, Is it possible to get an image sprite top right coordinates?

slender nymph
long lily
# slender nymph this is still a code channel

I think this relates to code (at least based on google it relates to Xcode issues) But if there is a better forum to post let me know please! Have been struggling with this for weeks

slender nymph
#

then show your code

slender nymph
fresh wing
slender nymph
#

just to confirm, are these Image components or Sprite Renderers?

fresh wing
#

Image

slender nymph
long lily
# slender nymph then show your code

Well it is a lot of code. I think it has to do with somehow not being able to compile on mac but zero issues on pc. Have you seen this error before?

slender nymph
fresh wing
slender nymph
#

that sets the anchor to the upper right no matter what the size of the sprite assigned is

fresh wing
#

Because this will make the parent Image go to the top, not the center

image.png
gaunt ice
#

set the pos and anchor of the small image rect tf

fresh wing
#

I only want that small logo on the topleft of the parent Image sprite, witout changing the parent locagion

gaunt ice
#

you dont need to change any setting of rect tf in large image

#

change the child instead

slender nymph
#

use id:browse to find a relevant channel to ask your question in. this isn't a code issue, which i pointed out yesterday before you'd even provided any details about the issue (other than it being a mac build issue)

fresh wing
slender nymph
#

why have you changed anything on the parent?

fresh wing
#

Here is the parent Image

#

This is the child Image

gaunt ice
#

do you have any layout group and the small image is not child of large image?

so @gaunt ice do you have any Idea?

have you tried my settings first to see if changing child rect tf still affect parent

but when I changed the Image and the image has a different resolution.
the small Image will stuck on the air

Hi guys, i need your help : I started Unity today, and i just want to move a capsule arround, i can move it with WASD but the problem is... Jump, a sort of jump work but i can go to infinity (not the goal) i just want a normal jump, jumping and then going back to ground: here's my code :
BTW: I'm really new and i know a lot about c# but +/- nothing about unity.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Windows.Speech;

public class PlayerMovement : MonoBehaviour
{
    // Start is called before the first frame update
    
    public float speed = 4;
    public float jumpForce = 20;
    RaycastHit _hit;
    
    void Start()
    {
        
    }
    
    void Update()
    {
        if (Input.GetKey(KeyCode.W))
        {
            transform.position += Vector3.forward * speed * Time.deltaTime;
        }

        if (Input.GetKey(KeyCode.A))
        {
            transform.position += Vector3.left * speed * Time.deltaTime;
        }

        if (Input.GetKey(KeyCode.S))
        {
            transform.position += Vector3.back * speed * Time.deltaTime;
        }
        
        if (Input.GetKey(KeyCode.D))
        {
            transform.position += Vector3.right * speed * Time.deltaTime;
        }
        
        if (Input.GetKey(KeyCode.Space))
        {
            
        }
    }
}

Thank's in advance

Anyone know how one would make a tree have physics (to fall on the ground) after it gets chopped by the player

summer stump
rich adder

#

quick question: Is [SerializeField] a viable option or are there better options to get references?

rich adder
merry spade
#

ok thank you

summer stump
rich adder
#

if runtime is needed, I'd do whatever DI unity allows (pass reference thru method)

merry spade
#

so getcomponent is also very good?

#

i thought that this is bad

#

but ok

rich adder
#

nah its still slow

merry spade
#

good to know

summer stump
# merry spade so getcomponent is also very good?

It just interates a list of components on the gameobject. If you only have a few, it's actually pretty fast. If it fails to find the component, it's pretty slow

Drag and drop serialized references also take time for the cpu to set up when runtime starts

merry spade
#

ok i understand, but sometimes its the best option right?

summer stump
merry spade
#

serializefield?

rich adder
#

eg. like Collision methods , Triggers, Interactions with rays so on

buoyant knot
slender path
#

I add a RB but it does not take the model with it and phases through the ground

buoyant knot
#

then you didn’t do it right

#

you would need to make a whole new tree object with a rigidbody

#

and if it phases through the ground, you didn’t set its collision properly

#

it would need a collider, model, etc and all that, you know

summer stump
# merry spade serializefield?

That is one way to allow it yeah

Personally, I use GetComponent in awake for most references, but it is sliiiightly slower (almost unnoticeable)

buoyant knot
#

assuming the tree is a part of the terrain

merry spade
buoyant knot
#

if the tree was already its own gameobject, then you’d need to alter it, and make a stump or something like that

summer stump
merry spade
#

what do you mean?

summer stump
merry spade
#

but then there is no reference?

summer stump
merry spade
#

ah wait

#

we were talking about different things

#

AHHH

#

now i understand

summer stump
merry spade
#

yes

#

i was too but i didnt consider using public

#

thats smart

#

xD

#

never thought about it

summer stump
merry spade
#

yeah

#

true

#

Hi, I have a class with a static variable that is initialized in the awake() method. Whenever i pause the runtime, change something in the code, and resume the runtime. Unity recompiles and the variable looses its value. Why is this happening?

summer stump
#

You should be stopping

rich adder
#

changing code at runtime will just give you missing script errors

Thanks guys, makes sense. Honestly i was supprised, that unity handled "hot reloads" if thats the term, pretty well so far and got used to it, because it allowed me to see instant results to changes i was making. Just not doing that would certainly solve the issue 😏

rich adder
quiet dune
#

I even changed conditions for if statements and removed code fragments and stuff like that which would take effect on a running game. I thought that to be a nice and convenient feature 😄

rare basin
#

Why is

Debug.Log("Local Y: " + letterDescription.transform.localPosition.y);

printing different values from what i see in the inspector? it's printing -500 and the inspector value is

image.png
polar acorn
rare basin
#

Ow

# 
    private void StartLetterScrolling(float desiredYPos, float duration)
    {
        scrollTween = letterDescription.rectTransform.DOMoveY(desiredYPos, duration).SetDelay(letterStartScrollDelay).OnComplete(() =>
        {
            scrolled = true;
            OnScrolled?.Invoke();
        });
    }
#

Im using DOTween to move a text

#

on Y axis (just scrolling it up)

#

i thought that doing DoMoveY on rectTransform will figure this out for me

#

i see that there is DOAnchorPosY

#

i'll give it a try

rich adder
#

yea use DOAnchorPosY for rect

rare basin
#

works flawless now

#

thanks

#

just to confirm

#

there is no such thing as local anorched pos?

rich adder
#

afaik anchored pos is kinda like the local pos for screen space

Very beginner question here but how do I change the speed of my animation as the sample button does not seem to exist my my animator window?

Have a question, its better to have 10 custom scripts with the function update, or only one update function with all things inside ?
only for performance reason

Hello is it possible to get an Image Source from an Image Component?

rich adder
#

cause its just a sprite/texture ?

somber kindle
rich adder
#

var mysprite = myImgcomponent.sprite

somber kindle
rich adder
#

probably

#

not sure how, I think you can use the bounds size and some math

silk night
#

Yeah position + bounds would be able to do that

#

!code

eternal falconBOT

#

congrats!

quiet dune
#

Is value = calculation(); if(value) more performant in any way than if(calculation())? I'm thinking in way of memory allocation/garbage collection

silk night
#

otherwise it doesnt really matter

quiet dune
#

Nah, I would just assign the value for readability and debugging

polar acorn
#

I think the second one actually looks more like the first when compiled

quiet dune
polar acorn
#

Nothing here is physics though, it's teleportation

silk night
#

Oh nvm, my fail

#

for some reason i thought it was using force at the bottom

unique laurel
#

what does this mean

summer stump
#

You cannot use it

frosty hound
unique laurel
#

oh ok

frosty hound
#

You have to use PlasticSCM (the version control package)

#

Or use something third party like git and save yourself the headache.

using System.Collections.Generic;
using UnityEngine;

public class SimpleMovement : MonoBehaviour
{

    public float movementSpeed = 5f;

    public Rigidbody2D rb;

    Vector2 movement;

    //update is called once per frame
    void Start()
    {
        movement.x = Input.GetAxisRaw("Horizontal");
        movement.y = Input.GetAxisRaw("Vertical");
    }

    private void FixedUpdate()

        rb.MovePosition(rb.position + movement * movementSpeed * Time.fixedDeltaTime);
    }
    // Update is called once per frame
    void Update()
    {
        
    }
}
#

is thier a issue with the code

#

the character refuses ot move

silk night
#

Check the values in the inspector

#

Oh and you just set the movement once on start

#

set it repeatedly in update

summer stump
green copper
#

what do I need to do during or after Instantiate() to let me manipulate the object afterwards with more code?

silk night
unique laurel
green copper
#

oh, so like GameObject thing = Instantiate(stuff);

summer stump
summer stump
silk night
unique laurel
silk night
#

oh nvm you edited it

polar acorn
unique laurel
summer stump
summer stump
green copper
# silk night yes

is there a way to do it so that the code runs before the Start() function on the new object runs? Or is that default behavior?

summer stump
polar acorn
silk night
green copper
#

I need to set a variable, 'size' of one of the new objects, and 'size' is used in a function in Start() to change the scaling

silk night
#

He wants code under instantiate to run before start

polar acorn
green copper
#

so

Instantiate(thing)
thing.size = 2
[Thing's Start() uses the size to affect scaling before it fully exists]

summer stump
polar acorn
#

Start doesn't run until the start of the next frame

green copper
#

So this should function?

Not what we said

Put the rb.MovePosition back in FixedUpdate

Move the INPUT into Update

Start only runs once. How would you get input during the game when it is in start?

green copper
polar acorn
summer stump
polar acorn
summer stump
polar acorn
#

Just use that component as the reference and save the GetComponent call

polar acorn
green copper
#

or do I need to also put a getcomponent in the instantiate somewhere?

summer stump

You don't really want GameObject references very often. Just make the prefab the type you'll use most

unique laurel
polar acorn
#

Essentially, if you ever need the prefab to do more than just exist you shouldn't be using GameObject

summer stump
polar acorn
summer stump
unique laurel
#

i changed start to update

    {
        movement.x = Input.GetAxisRaw("Horizontal");

        movement.y = Input.GetAxisRaw("Vertical");```

seems to have worked
green copper
polar acorn
polar acorn
#

You might have to drag the object back in since it's technically a new field you've made by changing the type

#

but other than that, nothing changes

summer stump
green copper
#

That broke the collision system with the projectiles for some reason....

polar acorn
green copper
#

no errors, the laser now just phases through the rock

#

collision was detected with OnTriggerEnter2D

#

and if collider.gameObject.tag == "asteroid"

polar acorn
green copper
#

asteroid still has a tag

#

Oh, wait

#

I think I just forgot to save my changes

#

is working fine on second attempt

#

hate it when that happens
