This does not appear to be a problem with your code.

[tight zenith]

Thanks!

[acoustic arch]

what's the different with

EulerAngles and LocalEulerAngles

[polar acorn]

One of them is world space, one of them is relative to the parent

[acoustic arch]

oh

how would you have a eulerangle in the world space?

oh

is it like

the x,y,z of world space

instead of your player?

[polar acorn]

The same way you have one relative to the parent, except relative to world origin

[acoustic arch]

so if my character moves forward on the x axis, and is always facing the x axis, yet it's not always on the world spaces x axis

idk if that makes sense

[polar acorn]

Position has nothing to do with orientation

If your character moves forward on the x axis that has nothing to do with euler angles

[acoustic arch]

i mean where it's facing

[acoustic arch]

can you give me an example

[ashen ferry]

create 2 empty gameobjects rotate one and make second a child of it look what changes

[polar acorn]

If you have an object with euler angles of 0, 90, 0 it's looking to the right. That object then has a child object with a local euler angle of 0,0,0. It's still looking to the right, because its parent object is

[acoustic arch]

and local is the child object rotating based on the parent

[polar acorn]

It's local euler angles is 0,0,0

it's world space euler angles is 0,90,0

[acoustic arch]

ohhhhhhhh

ok

i got it better now

parent object with euler of 0, -57, 0 then the child with local euler 0,0,0 is 0, -57, 0

suppose the parent was 0,20,0 and the child's local euler was 0,10,0

[polar acorn]

world space would be 0, 30, 0

[acoustic arch]

alright gotcha thanks

i'm on the self unity learning grind rn

[gleaming steppe]

Hi, do you think there's a way to affect meshes with code, like extruding at random positions?

maybe with probuilder ?

[timber tide]

usually you'd use something like a vertex shader for that, but I guess you can edit the vertex data directly

[gleaming steppe]

with HLSL ?

[timber tide]

Ye, unless you can make them with shaderlab yet]

[gleaming steppe]

ok will dig that, thx

[zinc grove]

Hey guys im playing around with coding a turret with a specific radius and I have the radius working how I want but I want to be able to show the radius in game. I use this for when the game isnt running and its correct

private void OnDrawGizmosSelected()
    {
        Handles.color = Color.white;
        Handles.DrawWireDisc(transform.position, transform.forward, baseTurret.targetingRange);
    }

I know this cant be used when the game is running and ive been trying to scale a circle sprite to the radius and a few other things but I just cant seem to get the correct size. This is probably a math thing I dont understand unless there is something similar to how the DrawWireDisc works that I dont know about.

[silent haven]

how do i change the material

[timber tide]

drag it on there

[brisk thicket]

I would do the circle sprite way on this

seems the most efficient

[timber tide]

Haven't touched gizmos for a while, but isnt handles the editor debug tool?

[brisk thicket]

Make the sprite 1 unit wide, so when u import it and u set the pixels per unit it has to be same width as that ,

and then if u set the scale to the radius of the turret it should be the same

[timber tide]

[wary sable]

hey, I'm looking for a way to write this method to avoid having to make a bunch of methods that are basically the same...

        foreach(Helmet h in inventory) {
            //show the item in inventory
            //There are no class specific fields or methods being called in this method
        }
    }```
Here inventory is a list<Item>; Item has children, like armor and weapon. Those children have children such as helmet, chestplate etc. Is there a good way to make this statement more dynamic so I don't have to make one for each child of Item?

[timber tide]

few draw methods in there

[timber tide]

Just make another outter loop, no?

[wary sable]

sorry not following?

[timber tide]

You're trying to loop over a list, and for each item find a helmet?

[wary sable]

sorry I completly forgot to add the part where I wanted to run this to find any specific child of Item. The method I show works, but only for the Helmet class. In the end I want to avoid having to make one of these for each armor piece and any other possible filters added in the future.

[brisk thicket]

can you give a working example of what it does so

is the loop looking for an item ?

[timber tide]

Like, at runtime you want a search box to filter out item names?

[wary sable]

basically condense:

  foreach(Helmet h in inventory){}
}```
```private void DispArms(){
  foreach(Gauntlets g in inventory){}
}```
```private void DispChest(){
  foreach(ChestPlate c in inventory){}
}```
into one method

[timber tide]

Probably want to look into regular expressions

and some parsing methods, but c# has a lot of libraries for that stuff

[brisk thicket]

do you want it to return an item ?

or check whether you have something in ur inventory?

[wary sable]

no, just be able to tell it what kind of item it needs to show, then it will instantiate slots for all of the items it finds of that type

I dont need to know if its there I just need to grab all instances of them

[ashen ferry]

so those classes need to share something a parent or interface idk

[wary sable]

using reg expressions, would I be able to define a type for it too look for?

[wary sable]

they do

they are all children of the Item class, which is what the main list holds. All attributes that are needed to instantiate a new slot prefab are part of Item, so I dont need to make calls to any of the child's properties, I just need to grab all children of a certain type

[brisk thicket]

okay

i understand

i think

[ashen ferry]

so u can have item type enum in Item class and loop through inventory grab all items with certain type and do stuff with them or I misunderstood

[brisk thicket]

he cant because the inventory has subcategories he would need to loop through

[wary sable]

if you click on any of the red slots it will bring up all items of that type in the green area

[timber tide]

Honestly, if it's not much you're probably fine with what you got.

foreaching over a list is pretty quick since if it's empty it's just a 0(1) operation

[wary sable]

yeah, it just hurts to write repeated code, it just always feels like there is a better way to do things lol

[wary sable]

the list would be the entire inventory so its still O(n), but I dont think there will be that many items in this game so time complexity isnt a huge concern

[timber tide]

Oh so you're trying to scan an inventory for each type of item eh

[brisk thicket]

List<Item> screenShowList //Green part
void disp(searchTerm){
  foreach(Item i in inventory){
      List<Item> tempList = i.returnAsList;
      
        if(i is searchTerm){
            screenShowList = i.returnAsList
        }
      
   }
}

something of this kind would work

syntax might be wrong

but this is how i would do it

[timber tide]

Yeah, what you can do is make a flag enum

send that into your foreach loop of the inventory

[brisk thicket]

i overcomplicated it

nvm

let me edit it rq

[timber tide]

if item enum type is any bit of this bitwise enum then you add it to a list

[brisk thicket]

this would work, you would just need to make a method in your inventory class that returns a list per type

[wary sable]

correct me if Im wrong, but I believe searching for types like this wont work

[timber tide]

https://giannisakritidis.com/blog/Enum-Flags-In-Unity/

[brisk thicket]

i have no idea

this isnt correct code

[timber tide]

good utility if you havent used bit enums before

[brisk thicket]

its more of the way to do it

enums will work yeah

[wary sable]

Ill look into it tyty

[brisk thicket]

enums like , armour, gauntlet, weapon

[wary sable]

would you suggest against using linq?

[timber tide]

way better than normal enums since you can check multiple types with one operation

and I don't really use linq but it's pretty powerful

[wary sable]

I just remember seeing someone say that its slow, especially for games but idk

[ashen ferry]

if u plan to have item to be helmet and chestplate at the same time that is

[timber tide]

They don't need to be a combination, each bit would be what's required to be added to the list

[ashen ferry]

how would that work Ive used flagged enums like twice in my life

[timber tide]

im pretty sure I use it a lot in one of my projects like that

cause I had a weapon system that I needed to check weapon requirements for mods

hummm

Yeah, you make a bit field with the bits you want flipped, you bitwise AND with the item's field and if the value is > 0 then you add it to the list

[ashen ferry]

so https://hatebin.com/myyopdlpru what do I change here so DisplayRelatedItems could get two types of items at once making use of flags

[timber tide]

https://learn.microsoft.com/en-us/dotnet/api/system.enum.hasflag?view=net-7.0

there's this too

when you don't want to use bitoperations lol

[ashen ferry]

is ur profile pic from transformice btw?

[timber tide]

ye

YE

[timber tide]

So this method will return back true if one or more enum flags are set, so for an example of the inventory scan, even if more than 1 item is flagged by different types, it should still be true and be added to the list Returns true if all flags are set it looks like

[ashen ferry]

I see

[zinc grove]

Turns out I am dumb and I was only calcing half the size of the radius so I just had to multiply by 2 lol. Thanks for the help

[timber tide]

Actually need to test it but there is different operations

rusty

[ashen ferry]

whats up with microsoft using food examples tho its always bread eggs or dessert

[timber tide]

https://i.imgur.com/n4dtGzU.png
Right so, 1010 would be the bitmask that you're looking for. 1101 would be the item enum type. Since the AND flipped and gave us back something greater than 0, we add it to the list.

ideally, your item type should only have a single bit set

[timber tide]

I think I was wrong about has flags, it looks for all bits to be set

[livid jacinth]

I haven't tested out anything yet, but I want to be prepared for it in case in happens: I have a boxcollider2d as a trigger in front of my player to check if there's something that is interactable. If I'm checking what the other tag is, what would happen if I ran into an instance where I have 2 different tags like NPC and Chest. When other.tag is called is it going to get the first one that entered or will the second one override it, or something else entirely?

[timber tide]

It will run each other's code I would assume

what order? Depends what one you collide with first.

[livid jacinth]

lol i left out an important part, I just have it there to change a bool whether there's something interactable in there and nothing else. but if there were 2 different ones in there and then I hit the button to interact, is it going to do both at one time?

[timber tide]

Yeah, probably if you're like standing near them using TriggerOnStay (I think that's the name?) and then you press a button, the next update will trigger one after another.

I'm not too sure if the trigger functions do any proximity checks on distance, but if needed you can sphere cast and do that yourself, thus making your own trigger detecting methods

So if you want something to trigger first based on distance when you're in proximity of both triggers

[livid jacinth]

ideally I'm only looking for one of them to happen

Hm, I guess I can have a variable to have the first one saved to, like a list that's only 1 item long and then have it get removed on the ontriggerexit

[timber tide]

In that case you'd want to set some type of member bool on your character probably

Yeah, there's a lot of extra logic here gotta think of

[ashen ferry]

upon pressing interact button box cast ahead of player and whatever is hit first with interactable script do stuff with it should be good

[livid jacinth]

alright, thanks for the help guys!

[timber tide]

That sounds like a good idea, if by chance it hit both, then do a distance check perhaps

[ashen ferry]

BoxCastAll I assume naturally returns array of who was hit first and last so u could just iterate and stop at first occurence of interactable element

idk tho

i spawn it in the player select and put it in a DDOL

you have to bring all the dependencies it has with you then

Structs are not reference types

But it's pretty unclear what you're asking

So you'd have to give a concrete example

[rich adder]

not sure what ur asking, did you close the IF ?

[crisp token]

I have this code that reassigns a Struct value to latestInput every frame via assembleInput(). Does this mean that, every frame, latestInput is referencing a new object? I'm guessing no since you said that structs are not reference types, so does that mean they are value types?

[crisp token]

^

[queen adder]

i only use #if Unity_Editor and havent really touched it any other way

[rich adder]

you have to close the if statement

[queen adder]

it's closed at line 77

if that's what you meant by close

[rich adder]

yeah you did #endif ?

not sure what that error complaining about tbh

if you want to exclude the whole file can't you just put it in the Editor folder?

[queen adder]

for some reason, my editor folder cant communicate with other scripts outside it

ig cause of assemblies

[rich adder]

is the script on a gameobject?

[queen adder]

yea

[rich adder]

tht might be the issue

I think

its probably trying to serialize the script for build but then it has exluded if editor

unity prob dont like that

[teal viper]

Still not clear. We don't see any types here, nor what happens in the assembleInput method.

But to clarify about structs, yes they are value types, so when you assign one it is being copied to a new place in memory and this new assignment doesn't affect the old value in any way.

[queen adder]

maybe may be

[crisp token]

okay, so lets say I had a struct that I passed as a parameter to a coroutine. That struct would be saved as a local variable in that coroutine, and any updates to the original struct variable would not affect the local variable because structs are a value type, correct?

[queen adder]

anyway, this doesnt usually happen in normal build, ig it only exist in the devt build

[wintry quarry]

No, it's not referencing anything at all. It contains the actual struct data

Because it's a value type, not a reference type

[crisp token]

ok, ty!

[wintry quarry]

Correct

[swift crag]

Note that no matter what, you'd always have a local variable

Even if it was a reference type, doing theParam = new Whatever(); would just overwrite your local variable

(but, conversly, doing theParam.foo = 1; would, indeed, modify the object that both the coroutine and the coroutine's caller have references to)

[crisp token]

what is the coroutine's caller ?

[swift crag]

whoever called the method

void Foo() {
  StartCoroutine(MyCoroutine(anArgument));
}

Foo called MyCoroutine

Hello, I am attempting to use a custom GUI to update my Sound Manager Volume like so

public class SoundManagerEditor : Editor
{
    SoundManager soundManager;
    float desiredMusicVolume;
    float desiredSoundVolume;
    private void OnEnable()
    {
        soundManager = (SoundManager)target;
    }
    public override void OnInspectorGUI()
    {
        
        base.OnInspectorGUI();
        if (soundManager != null)
        {
            desiredMusicVolume = EditorGUILayout.Slider("Music Volume:", desiredMusicVolume, 0f, 1f);
            soundManager.MusicVolume = desiredMusicVolume;
            desiredSoundVolume = EditorGUILayout.Slider("Sound Volume:", desiredSoundVolume, 0f, 1f);
            soundManager.SoundVolume = desiredSoundVolume;
        }
    }
}```

The issue I am having is that I'm not sure how to save the data that I am changing in the inspector. Ideally I'd like to have persistent data between play mode and edit mode and be able to have the data saved after deselecting the object. I really do not know where to start. I looked around a fair bit on the forums and tried SetDirty() to no avail and I am struggling to figure out many other promising methods. Can someone point me towards some useful docs on the subject? I tried asking in [#↕️┃editor-extensions](/guild/489222168727519232/channel/533353544846147585/) but I didn't really see any response. Is anyone here able to help?

I also looked into using serialized properties but the issue is that I am trying to access a value setup with getters and setters which makes the values non-serializable in the first place

[teal viper]

Not entirely sure what setup you have, but if the values are not serializable, then they are not saved.🤷‍♂️

They would be reset as soon as the object is reloaded from disk(deserialized).

[slate ingot]

when do I need to remove listeners

let's say this

class ClassB {
  
  void Init() {
    ClassA.onEvent.AddListener(onEventTriggered);
  }

  void onEventTriggered() {
    // do something
  }
}

I know that if I destroy ClassB, I have to remove the listener to ClassA

but let's say ClassManager destroys ClassA
do I have to remove the listener from ClassB to ClassA using ClassManager before destroying ClassA?

class ClassC {

  void DestroyClassA() {
    ClassA.onEvent.RemoveListener(ClassB.onEventTriggered);
    Destroy(objClassA) // lets say there's an object for ClassA
  }
}

based on logic I don't need to remove the listener since the "data" is inside the onEvent class so when destroyed everything would be removed

but just wanted to ask if my assumption is correct

[burnt vapor]

With regular events you should unsubscribe the subscription you make when you dispose of an object. In the case of Unity you can use OnDestroy. I imagine this is the exact same with UnityEvent types, though these might unsubscribe under the hood when destroyed.

It doesn't hurt to just unsubscribe it.

[cunning rapids]

Why is the draw animation only playing once? Even though the active state is toggled back on?

[burnt vapor]

The Awake state only runs once

So I guess your object already exists

Or are you destroying it?

[cunning rapids]

But the active state is toggled off

[cunning rapids]

No

[slate ingot]

yeah, no worries, I just want to ask to find out how the innerworkings of coding work, and that is it necessary to unsubscribe when the object that has the event is destroyed

[burnt vapor]

The Awake state does not run when you activate a gameObject

What you're looking for is OnEnable and OnDisable

I highly suggest you don't disable an object to simulate weapon switching. Give proper states that play the animation and only disable the object if it's no longer used.

Setting object activity should only be done if you actually don't use it and you should not use it for actual behaviour because you're just limiting yourself

[cunning rapids]

Elaborate please

[burnt vapor]

See last message

[cunning rapids]

I use animation states only to play necessary animations depedning on an event

Whether it's weapon switching or reloading

How can you swap to an entirely different game object without disabling the first game object?

[cunning rapids]

This is my animation controller

[topaz mortar]

Is there a "simple" guide on a functional inventory system anywhere?
I'm currently following a 24 episode YT guide with each video 10-15 minutes, most of it works, but it's so complicated I can't fix the few things that don't work 😦

[cunning rapids]

How do I do that?

[cunning rapids]

Depends what type of inventory you're looking to implement

[burnt vapor]

Create an abstract class that has an "OnSelect" and "OnDeselect" method to implement, and play the animation in there

[cunning rapids]

if it's a simple swip-swap it shouldn't be too hard to find one

But the style of Minecraft may be a little more complex

[topaz mortar]

Anything basic, like runescape like inventory, you have a bunch of slots where you can put items, some are stackable, some are edible, some equipable, ...
I can extend it further myself if I have the basics

[burnt vapor]

Then have a state on the weapon that indicates "UnSelected", "Raising", "Selected", "Lowering" and the OnDeselect class should specify when the state becomes "UnSelected". Then set the weapon on inactive

It's a very rough idea on what I would do

[cunning rapids]

I'm terrible at animations may you please explain a little simpler?

[burnt vapor]

Just do what you do currently, it will probably work fine for now

[cunning rapids]

This is my hierarchy

[burnt vapor]

I more or less exist to give tips and to fix bugs, not refactor projects 😛

[cunning rapids]

I understand but I don't know what to do/what is recommended for weapon swapping

Why is disabling objects impractical?

[cunning rapids]

I've never really worked with that type of inventory tbh

I'l try to find a tutorial

[topaz mortar]

the issue with most tutorials is that they work fine the first 3-4 hours you spend on them, but then later on something doesn't and since I'm a noob I can't figure it out

[cunning rapids]

https://www.youtube.com/watch?v=AoD_F1fSFFg

This doesn't look too bad

[topaz mortar]

I spend like 8 hours building this one and now some of the functionality doesn't work and I just dunno lol

[cunning rapids]

@burnt vapor

[burnt vapor]

It seems like your flow is to just disable the object when you switch instead of having a proper state system. Works fine as a basic system but you're very limited.

It's something you'll learn as you learn more about game development probably

[cunning rapids]

I might change the system later on but for now I'd like to stick to the OnDisable/OnEnable system

Speaking of, how do I change my draw animation system to draw when it's enabked

Actually nevermind I'll try myself

I'll come back if I have any issues

he explains it well as well

looks really nice, i tried it myself and failed massively

so good job

[noble rover]

Yea its so much work kind of insane to be honest, I've just got the bare minimum probably not even setup right haha, some god of a man made a outline edge asset using the same techniques t3ssel8r does which massively helped me get a start, I pretty much made the toon shaders and grass been lots of tinkering today to get the color palletes right haha

[brisk thicket]

yeah cba to do all of it haha

i would pay tessel8r to give me his shader tho

[noble rover]

Deleted the asset link not sure if I can post haha

But I used an asset called upixelator or something like that shit was a god send to make the outline system and its well optimized

The toon shaders though have been a nightmare to setup spent hours messing around with it managed to get it mosty working other than on the grass thats another days problem for me haha

Can someone explain to me why the move tool is at the bottom and not at the feet or on the body of the character? 😄

It is kinda weird to work like that

[restive badger]

It's probably related to your model you might want to adjust it's pivot in blender and reimport it

[late sinew]

So i am creating a painting images feature in an application for children, Can anyone suggest a tested approach to move in that way, also i need to have brushing the image like effect.

Not click and paint appears

Oh, I got it from mixamo 😄

You can also create an empty gameobject as a pivot then attach your character to that empty object then align it

This should also work

[zealous oxide]

https://hastebin.com/share/uduxuzidew.csharp i've got a script for enemy projectiles & and a script for my characters combat entity https://hastebin.com/share/ivesucosuh.csharp ; im trying to make the projectiles get reflected on hit but each time the character hits the projectile, rather than reversering the direction its going, the projectile just destroys itself

[vast yoke]

are they definetly getting destroyed? not like refelcted down through the grown or somthing?

[worn egret]

are you sure it is not going inside this condition?

[zealous oxide]

on the debug log if i hit the projectile whilst attacking, it tells me the bools change but i dont get a debug log saying "enemy projectile hit", also the player doesnt take any damage when the bullet gets reflected so its working half way there

[zealous oxide]

let me double check this

[zealous oxide]

i'm guessing this should have probs said (lethalToPlayer == true) so i've updated that but its not fixed my issue

i've added this debug line but it never shows in the console so i dont think thats what is destroying the projectiles

[spare mountain]

when you Destroy an object, it stops running its scripts
it's not going to print if you tell it to delete itself and stop running its scripts before it gets to the print statement

[zealous oxide]

i've moved the new debug line to before "destroy (game object)" and its still not showing when i "reflect/attack" the projectile

im going to take out the "destroy" line and see what happens

[spare mountain]

so the first one is showing but the second one is not?

[zealous oxide]

it gets destroyed anyway

[spare mountain]

both should be printing if they're right next to each other

[zealous oxide]

so whats happening is that when i attack/reflect the projectile, it says "projectile reflected", tells me the bools are changing, as per the previous screenshot, but theres no messages about the enemy projectile being destroyed or hitting the player if that makes sense. even when i've taken out the "destroy(gameObject)" line, the project still gets destroyed when reflected

[spare mountain]

is there any other destroy in your code?

also you mean the object gets destroyed not the project right

[spare mountain]

could that be destroying it

also you did it again

[spare mountain]

.

[zealous oxide]

the projectile is getting destroyed not the player

[spare mountain]

print before the destroy

[zealous oxide]

yeah i've just changed that, thanks

[spare mountain]

👍

[keen dew]

It's not true though

[spare mountain]

it's not?

[zealous oxide]

"enemy projectile expired" doesnt come up when i "reflect" it

[keen dew]

Destroy happens at the end of the frame, and there is no language feature that could stop a method from running midway through

(except throw/catch)

[spare mountain]

I'd have to test that

[teal viper]

There is return👀

Language feature

[keen dew]

Touche

But you can't call another method that would stop the calling method

[teal viper]

Yeah

In fact you can't call a method from outside the running method at all.
Unless multithreading is involved.

[zealous oxide]

right so the projectile isnt getting destroyed, its getting yeeted

i managed to find it after pausing the project right after i hit the proj

[teal viper]

Sounds like what projectiles do.😬

[zealous oxide]

right but the movement speed that gets set when theyre instantiated is slow af. for some reason on the reflect they get blasted the other way so quickly you cant tell it happened

ok what I think is happening is that the projectiles transform is somehow being reset because they all end up on the far left of the screen when I hit them

[teal viper]

The answer is probably in the Movement method.

Unless there's another place where you move the object.

[teal viper]

Note that you're subtracting the position under the first if and setting it in the second.

[zealous oxide]

best way to approach this? have a second method called ReverseMovement?

[teal viper]

Best approach would be to use physics. But if you really want to move them manually, implement a velocity vector field and just reverse it after collision.

[timber tide]

This is 2D right?

[zealous oxide]

yeah!

[timber tide]

When I do like reflection and chain, I just change its direction

and keep on adding a speed to it

[zealous oxide]

ok thats definately a much starter way to do it

[keen dew]

The movement method doesn't track position, it just calculates how far from the spawn point it has moved

[gaunt ice]

You cant just -movement…. It is not returning direction vector

[keen dew]

So when it changes direction it just swings to the opposite side of the spawn point

[gaunt ice]

You can change the spawn point to hit point and treat it as start, a bit weird but it should work

And rotate the transform too

[zealous oxide]

yeah this is what im trying to do now, indeed its rotating far from its spawn point

[topaz mortar]

Could someone explain this syntax to me please?
OnItemBeginDrag?.Invoke(this);

[teal viper]

? Is checking if the reference is null and if not, runs the part on the right,
Which looks like a delegate invocation.

[worn egret]

If OnItemBeginDrag is not null, it will call Invoke

https://www.c-sharpcorner.com/blogs/null-conditional-operator-in-c-sharp

[topaz mortar]

it's from an inventory building tutorial and I just don't really get why it's done this way

at the top I have:
public event Action<InventoryItem> OnItemClicked, OnItemDroppedOn, OnItemBeginDrag, OnItemEndDrag, OnRightMouseBtnClick;
and then for each of those I have one of those invoke thingies:

{
    OnItemDroppedOn?.Invoke(this);
}```

[teal viper]

It's a very common way to invoke an event.

[worn egret]

It is just a shortcut for:

if(OnItemDroppedOn != null)
{
  OnItemDroppedOn.Invoke();
}

[teal viper]

Might need to learn about delegates/Actions for better understanding.

[strong wren]

It would throw an exception without it if there were no listeners

[topaz mortar]

what is the difference between my OnDrop function and the OnItemDroppedOn event?
why not just directly "access" the event?
I don't really know how to explain my confusion lol

I understand what's happening, I just don't understand why it's with the extra step

[worn egret]

One of the reason could be cleaner code, or the function OnDrop could call some other events or methods or set some values in future.

Most of the time in big projects, the author might have modified the method numerous times but forgotten to refactor the code properly.

[timber tide]

Are these events being called outside of the class?

[teal viper]

Yeah, it's mainly for cleaner code. You don't want every class to reference every other class in your game. Events allow you to build a hierarchy of responsibilities and reverse dependencies

[timber tide]

Usually this approach is done on the view (UI elements) and passed into the logic portion (your inventory logic)

[topaz mortar]

that's what the guy in the video said, but I don't get it lol

yeah seems like that's what is happening

it just seems so complicated to me

[worn egret]

It is good idea to practice it in the early stages of the project. Because once the project gets big, it is really difficult to change even small things.

[topaz mortar]

but I understand it a bit better now, thx 🙂

[timber tide]

When you think about it, it's kinda weird to pass your inventory reference to every slot, but instead doing this way you just bind an event of each slot to your inventory

[keen musk]

hi
so.... horse riding
i have been trying to implement a system for over a month now and i think like i might explode soon...
anyone has any ideas on how i could implement the system?

[wintry quarry]

"horse riding" is incredibly vague. You'd need to explain exactly what you want

Nobody knows anything about your game

[keen musk]

to be able to ride a horse using raycast when pressing f
when mounted, the player should follow the horses movement and control it

when f is pressed while being mounted, the player will get unmounted and "teleported" next to the horse

[wintry quarry]

Again nobody knows anything about your game so this is still extremely vague

You'd also have to explain which part you're struggling with

[keen musk]

what more do you need to know?

[wintry quarry]

The style of the game would be a good start

Is this a 2d side scroller?

First person 3d game?

[keen musk]

https://pastebin.com/ZfrMiQbg
this is my current script
when i mount the horse, the player stays on it and i can move in the scene view the horse and the player will move aswell
the problem is with the unmounting (will send a video in a min) but the problem is that the collider just goes wherever the frick it wants and just like deattaches from the player

its a 3d first person game

[wintry quarry]

Is there a reason you're manually doing this?

player.position = playerMountPoint.position;
            player.rotation = playerMountPoint.rotation;```

Why not just make the player object a child of the mount point

Anyway if your player uses a dynamic rigidbody you'll need to make it kinematic for the duration of being mounted if you want it to actually follow its parent

[keen musk]

didnt work

this is the vid i said ill send

look at the scene view in the right

[wintry quarry]

^^

You haven't explained yet how your player normally moves

[keen musk]

what do you want to know?

he uses rigidbody, a collider and scripts
need the scripts? the rigidbody settings?
what do you need to know?

@wintry quarry you here?

[gloomy timber]

Hey, someone is working on RTS?

[polar acorn]

Given the number of people working on games at any given moment and the breadth of genres people like to play, my guess is probably yes

[gloomy timber]

was an invite to talk about rts, digiholic ahah

cause it's my first attempt and want to know how to organize scripts

[silent valley]

https://hatebin.com/pqhubmrmwc

Hi. I am just wondering if anyone can see an issue to why the character doesnt rotate to where the mouse is.

it was working before which is why I'm confused

[hard yarrow]

Hey does anyone know how to fix this?

[wintry quarry]

It was working before what?
I don't see anything in this code that would rotate a character at all

[silent valley]

It was. yes. I was following a series and it was working. I come back today. and it isnt

[wintry quarry]

Again - there is no code here at all that would rotate any object

I would guess that yesterday your code was different

I suggest following the tutorial again

[silent valley]

I have. So many times

without skipping

[wintry quarry]

^ seems something was skipped

¯_(ツ)_/¯

[wintry quarry]

The error explains what's happening pretty well. You have a broken script on the prefab

you can't save it until you fix that

you also have at least one compile error

that will need to be fixed before anything else

[swift crag]

        Vector2 aimDirection = mousePosition - rb.position;
        float aimAngle = Mathf.Atan2(aimDirection.y, aimDirection.x) * Mathf.Rad2Deg - 90f;

This computes a vector pointing from the player position to the mouse position.

It then computes an angle from that vector.

The function then ends.

Characters are not rotated by wishful thinking.

If it was working before, then your code must have previously done something with that angle variable.

[silent valley]

I need a vacation. fml

rb.rotation = aimAngle;

was needed. thats all

Thanks @swift crag & @wintry quarry . you're continued help is very appreciated ❤️

[swift crag]

That will do it.

One useful thing: your IDE should be highlighting unused variables.

Notice how the second myVar is gray.

An unused variable suggests that you forgot to do something.

[silent valley]

yup.....

[swift crag]

in this case, it'll say "unnecessary assignment"

because, indeed, that assignment accomplished nothing

[silent valley]

trust me. I feel like a melon. :p

I need to configure it better. I struggle seeing the different blues

[noble rover]

Been working on creating a 3D Pixel Art system heavily inspired by t3ssel8r, Im very new to unity so pretty happy with what I've got so far, and wanted to share, struggling to get the toon lighting to apply to the grass though any tips https://youtu.be/o5xl6B5mrs0

[tawdry mirage]

i have two 3d objects, object A is behind object B, but i need A to render above B, how to do that? if i change renderer.material.renderQueue nothing changes

[rich adder]

maybe look into renderer features if you're in URP

[tawdry mirage]

i'm in URP but i have no idea what to do

[wintry quarry]

A bit old but useful https://www.youtube.com/watch?v=szsWx9IQVDI

[rich adder]

^ little note on this : LWRP is now URP Universal Render Pipeline

(if name confuses u or anything)

[tawdry mirage]

thank you, but it is not what i need. I need some kind of render order so ~10 objects will not clip through each other while being on same z in pseudo 2d
i believe you could do that with ZTest Always and setting material renderQueue for each object in built-in renderer

[rich adder]

why not use the order number on the sprite renderer then ?

[shadow flame]

how do i make dont destroy so music will stay playing

[tawdry mirage]

cannot use it with 3d, right?

[rich adder]

I thought you said 2D

[rich adder]

literally dont destroy on load has an example just for this usecase

[tawdry mirage]

pseudo 2d, navigation is 2d but 3d models on zero Z

[rich adder]

huh if its 3D models then ur using the 3D render then look into the render feature ? i dont understand lol

it literally allows you to mess with render order so idk

[tawdry mirage]

you mean rendering layers? i'm complete noob so i don't understand what you mean by "render feature"

[rich adder]

did you look at the video ?

it explain its purpose

here is another example of renderer feature and what you can do @tawdry mirage
https://docs.unity3d.com/Packages/com.unity.render-pipelines.universal@12.1/manual/renderer-features/how-to-custom-effect-render-objects.html

[wintry quarry]

if the objects are 3D why not just put them physically in the desired order

are you using an orthographic camera?

[tawdry mirage]

yes

[wintry quarry]

then you are free to move the objects further/closer to the camera to achieve the desired ordering

[tawdry mirage]

i think point light will not look so great

[delicate portal]

Hey, why cant I invoke this function?

[timber tide]

#archived-shaders #archived-lighting

[noble rover]

Thank you apologies

[rich adder]

you invoking from wrong class

[keen musk]

I think I found a solution to my horse problem
will update

[rich adder]

you would need to do player.Invoke()

Invoke looks for method on monobehavior

[polar acorn]

Does the class you're calling Invoke on have a function named ChangePlayerStateToIdle?

[delicate portal]

Yes it does, I even put nameof, to make sure

[delicate portal]

and then, strings?

[polar acorn]

Show the full !code of the class

Doesnt exist in the current context then

[shadow flame]

https://hatebin.com/lywwdjdtzo idk whats wrong

[rich adder]

is player a script / mono ?
send script #💻┃code-beginner message

[polar acorn]

Duplicate script

[shadow flame]

yes thanks

[rich adder]

sorry because ur usingnameof instead of string, you would do instead
player.Invoke(nameof(player.MethodName

[delicate portal]

ah okay let me try it

[gray crest]

Are there any resources to better understand how to read the profiler. I have parts of my game that drops frames but I have so many objects doing their own thing I'm not sure what I need to try and optimise, going through them one by one will take ages.

[delicate portal]

well, not really

[wintry quarry]

You basically want to just look at the largest time-takers first.

[rich adder]

wdym ? whats wrong? Just tested it and works..

[gray crest]

Is that the tall spikes?

[rich adder]

@delicate portal also just use a coroutine lmao

[wintry quarry]

spikes imply you're looking at the chart at the top

that just tells you how long the whole frame took

[delicate portal]

I dont like the pattern

[gray crest]

Yeah I am

[wintry quarry]

when you are looking at an individual frame, the section at the bottom breaks down how much time is spent in individual scripts/functions etc

that's where you need to look to find your bottlenecks

[rich adder]

Invokes suck because they can't be stored into variables / stopped.
also you can't yield them like coroutines can

[polar acorn]

Get over it

[delicate portal]

Thats true yes

Maybe Ican use a tiemr

With update

[rich adder]

naa

[gray crest]

I'm just watching the spikes while the game runs but I have so many things spawning from object pool I'm not sure which one js cause the lag

[wintry quarry]

I just told you how to identify the issue

[wintry quarry]

Look at the bottom part:
It's a breakdown of how much time each function is taking

the biggest/widest things are the slowest

and need to be looked at

[rich adder]

public void Timer(float time)
    {
        StartCoroutine(Timed(time));
    }
    private IEnumerator Timed(float time)
    {
        yield return new WaitForSeconds(time);
        //thing
    }```

myscript.Timer(3);

[gray crest]

Right so is it colour coded or is it the length that I can gauge which script is the issue

[delicate portal]

Yeah thanks

[tawdry mirage]

just in case someone would do something similar: default URP Lit shader lack something that Shader graph generated URP Lit has. In Shader graph window set Depth Test to Always and then you can change material.renderQueue at runtime and it will work.
Copy-pasting default URP Lit and editing ZTest there didn't work.

[rich adder]

This can be very powerful, you can also pass functions inside as params

[rich adder]

So you solved it?

[tawdry mirage]

yep. But now i need to learn shader graph lol

[delicate portal]

Nice

[rich adder]

better than Shader code!

[manic shore]

Where do you go to add the Nav Mesh Agent?

[rich adder]

Are you in 2022?

[polar acorn]

Add Component

[manic shore]

Yes

[rich adder]

You need the AI package

then you can Add Component

no clue why they decided to extract it out of the editor 🤷 maybe its just "clutter"

or easier to update

[polar acorn]

It lets the package be updated without needing to change editor versions

[rich adder]

yeah figured it was that , makes sense

[manic shore]

Where can I go to see the packages I need to download?

[rich adder]

wdym? you see the screenshot

[manic shore]

Okay, nvm I got it

[swift crag]

It's nice that it's finally been moved entirely into a package

it was in a weird limbo state for a while

[rich adder]

yeah the AI "extras" was annoying have to install to get navmesh surface

glad its all unified

[sterile river]

Hey 👋
So I imported a model from mixamo and followed a tutorial where I should extract the materials. Now I got this message in the console. The materials are in my folder though:

Will I face problems? 😅

[rich adder]

no its just edit window bugged out you can clear it and ignore it, also not a code question

[small otter]

Does GameObject.Instantiate() set the relative position to 0,0,0 by default?

[wintry quarry]

It has a parameter for the position

[polar acorn]

It uses whatever the position of the thing you're instantiating has, unless you specify it

[rich adder]

yea default pos without specifying is vector3.zero world pos

[rich adder]

wait does it?

interesting..thought it spawned at 0

[polar acorn]

Pretty sure it does. I'm not actually able to test it at the moment

[sterile river]

Thank you! Yeah I didn't know where I should put the question into, my bad

[rich adder]

ahh Ok I guess I did remember correctly.
cause it could've sworn was one of my first unity mistakes few years back, was wondering why it wasnt spawning by spawner 😅 ..

I suppose if you just spawning object with scripts, world 0,0,0 is no big deal

[delicate portal]

Hey, how to really use EventArgs?

[wintry quarry]

I don't recommend using the EventArgs pattern in Unity

it leads to unecessary memory allocation/garbage collection

better to define your own delegate type or use Action and its derivatives

[delicate portal]

What I want is to Store the plant from the event, and that is a type of 'BasePlant'. So something like StorePlant(e.referenceToThatBasePlantFromWhereTheEventWasInvoked)

[wintry quarry]

right you want to pass the plant reference through the event

[polar acorn]

https://gamedevbeginner.com/events-and-delegates-in-unity/

[wintry quarry]

do either of these:

public delegate void PlantEventHandler(Plant p);
public event PlantEventHandler OnHarvest;```
OR
```cs
public event Action<Plant> OnHarvest;```

[delicate portal]

a simple EventHandler is not the greatest approach then I assume

[wintry quarry]

EventHandler is not simple

[delicate portal]

I can invoke actions the same right?

[wintry quarry]

EventHandler is a catchall pattern intended for use in standard .NET application

but it creates a bunch of extraneous objects

this is simpler than eventhandler

[wintry quarry]

you invoke them with whatever parameters the delegate type you are using requires

in this case, a Plant

[delicate portal]

Sure, for example like this:
I just cant figure out the correct synax with actions

[wintry quarry]

you're using the wrong parameters

you passed in this

which is not in the parameter list

[delicate portal]

My bad of course

[wintry quarry]

if you want to pass this in, you need to have whatever type that is as one of the parameters in the delegate type

[delicate portal]

Sorry, again, how can I liste to an action from another class and then pass it in pars?

[delicate portal]

Yeah Thank you

[wintry quarry]

the other class doesn't pass in parameters

it receives them

listen to an event with theEvent += MyListener;

MyListener must also match the delegate type

so for example

void MyListener(Plant p) {
  p.Whatever();
}```

[stiff stump]

how to check if two trigger collider are overlapping?

[delicate portal]

So now I can StorePlant(obj)

[wintry quarry]

OnTriggerEnter or direct physics queries

[delicate portal]

or p, whatever

obj is the plant

[wintry quarry]

oh sure

[stiff stump]

which physics method is needed?

[wintry quarry]

inside the listener you mean?

yeah

[delicate portal]

Thank you, you helped me a lot with this Action stuff

I'm gonna use theese a lot more

Well, EventHandlers are prefereable for me but still...

[wintry quarry]

what does event handler give you that you are missing?

If you want to pass the "source" object, you can do that just as easily here

[polar acorn]

why

[wintry quarry]

public delegate void PlantHarvestHandler(Player source, BasePlant plant);
public event PlantHarvestHandler OnHarvest;

OnHarvest += HarvestCallback;

void HarvestCallback(Player source, BasePlant plant) {
  // whatever
}```

[sterile river]

Hey, I am using Visual Studio 2022 and in the IDE itself it doesn't show me errors.
I intentionally wrote some errors but it doesn't say anything. In the Unity editor I get the errors but how do I enable them in Visual Studio?

[polar acorn]

!ide

[eternal falcon]

[sterile river]

Thanks ❤️

[silent valley]

Error is ;expected and invalid expression term '}' ... I understand what the errors mean, all my "}" are good and my ";" are good. I'm guessing it's the way the code is put together

[short hazel]

Where the error is, you have the { and } swapped. Refer to the other if statements.

{ opens, } closes

[silent valley]

fml

Not embarrasing at all. Thank you

[rich adder]

this is where something like if(gunheat >0 ) return;

clean up those nesting

[silent valley]

I need to read up on returns.

not too sure how to use them in something like this

[rich adder]

just returns out of the function, in this case the function is void. so it doesnt do anything below it and doesn need to return a value

its like saying , dont do the rest of this code and leave early

[silent valley]

that. makes sense. i'll do some reading now. Thank youu

[dusky finch]

i did this but vs code still isnt underlining code or autocompleting

[rich adder]

you did what exactly

[dusky finch]

went on the installer clicked modify on my install and checked game development

[summer stump]

There are more steps

[short hazel]

You're talking about VS Code but showing screenshots of the installer for Visual Studio 2019/2022??

[dusky finch]

ohh ye mb

[short hazel]

These are two different programs, although named similarly

[dusky finch]

im used to typing vs code

[short hazel]

Post a full screenshot of VS, with the Solution Explorer tab visible

If it's not there, select View > Solution Explorer

[summer stump]

Also, i didn't see earlier (just jumping in, sorry if that causes confusion), but did you get the package inside unity?

[dusky finch]

it says its incompatible

i just noticed it

[short hazel]

Right-click and select "Reload with dependencies"

[dusky finch]

seems like that fixed it

[silent valley]

Just curious about these errors. It'll happen. I'll comment what part of the script i think is bad. it'll work. I'll uncomment, It'll work once then spam this error again.

[short hazel]

Select the error to reveal the stack trace in the bottom half section of the Console. This contains information on where the exception occurred.

[tender stag]

how would i make it so each process type displays its own information?
https://hastebin.skyra.pw/ajijuwenul.csharp

this is the wood item for example

what if i didnt want like process outcomes or temperature to show on a smelt process type

[silent valley]

I havent a clue how to debug that. I did look it up on my other project and couldnt find a solution

[short hazel]

Look at the stack trace, as I said

[tender stag]

restart editor?

[short hazel]

Posting it here is an option

[silent valley]

done that

[silent valley]

shall i just post it or but it in hatebin or something?

[swift crag]

Sure, if it's very long.

[short hazel]

Here in a code block if it's less than 10 lines

[silent valley]

https://hatebin.com/kunbrbemyq

[short hazel]

Okay, reading stack traces tutorial time

It's read from top to bottom. The first two lines are the error and the message

The following lines point to where in the code it happened

UnityEditor.SerializedObject.FindProperty (System.String propertyPath) (at <fe7039efe678478d9c83e73bc6a6566d>:0)

UnityEditor.SerializedObject.FindProperty (System.String propertyPath) : method in which the error occurred
at <fe7039efe678478d9c83e73bc6a6566d>:0 location and position in the code.

This one is special because there is no file name and the line number is 0, indicating it didn't happen in your code.
If all the lines don't point to any of your code, the error is internal to Unity and can be ignored

[tender stag]

anyone know if this is possible?

without editor scripts

[polar acorn]

Custom inspectors

[silent valley]

oh wow. Seems straight forward if I learned the meanings in it.

[tender stag]

could i like use SO's somehow?

like make a script called ProcessData

[silent valley]

So does this mean that unity is having a buggy moment. aka it working once then doing that?

[swift crag]

If it's persisting, I would suggest resetting your layout. Also, check if the error pops up when a specific object is selected

[late burrow]

text component can run functions when clicked on right

[swift crag]

TextMeshPro can add "links" to the text, iirc

You can also detect clicks on any UI element

if you just want to click somewhere on it

[silent valley]

I did notice it was random.

not aimed at any specific object

[short hazel]

When it comes from your own code, you'll get a file path and a line number, like this

(at Assets/Scripts/MyScript.cs:32)
// File 'MyScript'             ^~ Line 32

[silent valley]

every error like this I've gotten I havent gotten it like that. Even on my other project

maybe bad install of unity

[short hazel]

You'll get them once you start creating more scripts for sure

Unless you're really good and produce flawless code
Or you managed to squeeze through all the edge cases that would cause exceptions

[silent valley]

gotcha. So they dont happen like that if for example, too many things in scripts are public and interferring with one another. That'll show the location like you showed?

[silent valley]

nope

[eternal needle]

you probably just dont notice when you do get the errors with your own code. try just writing something rn that'd result in an error and then look around in the console

itll always print the stack trace

[shadow flame]

why is it not coming

[silent valley]

Thank you so much

[polar acorn]

Does the class name match the file name

[shadow flame]

?

[short hazel]

It really depends on the exception type and the error message, but exceptions always happen when the game runs (unless you make scripts that run in the Editor).
Compiler errors happen when the game does not run, when you modified the code but there is a syntax issue, or type check issue whatever. Compiler errors will prevent you from playing the game.

[polar acorn]

Does the class name match the file name

[shadow flame]

idk what that means

[polar acorn]

Does the name of the file match the name of the class inside it

[rich adder]

prb compile errors

oh nvm my discord didn't update

[shadow flame]

yes

[rich adder]

wtf

[polar acorn]

Do you have any compile errors

[silent valley]

Thank you. It would play for half a second then crash.

[swift crag]

Show the entire declaration of the class.

Perhaps it's not a MonoBehaviour.

[rich adder]

if this is 2022, try to trigger a manual refresh / recompile @shadow flame

rightclick project window and hit Reimport (not all)

[swift crag]

ah, but that suggests it is a MonoBehaviour

[short hazel]

You may have "Error Pause" option enabled if play mode pauses when you receive an error.

[swift crag]

ctrl-r or cmd-r will ask Unity to reload, or you can do what navarone suggested

(and make sure you've saved in the code editor, of course)

[shadow flame]

i;ll try that

fixed

thanks

[silent valley]

i do.

[tender stag]

whats a better way to make the process types?
https://hastebin.skyra.pw/idavevudeq.csharp

i dont really want all of the info on the item data

i was thinking of like a scriptable object for ProcessData

but im not sure how that would work

cause this looks really messy

[quaint lynx]

I have an array of vectors that needs constantly updating basically every tick. is it okay to completely clear the array and remake it each time? I am wondering if that is very intensive

[short hazel]

Remaking it, as in doing = new Vector3[n] each frame? Yes expensive, especially if the array is large. Use the same array but replace the vectors in it instead

[acoustic arch]

how can i cap a variable

like i want it so that the players first person camera can't go completely upside down so how can i make it so the X can't go over 90/-90

[short hazel]

Use Mathf.Clamp()

[acoustic arch]

thanks

[empty juniper]

i want to make my plane shoot, so i did an instantiate inside an if, and im not getting syntax errors but it doesnt work anyone got any tips

i have the bullet prefab as a child of the plane and it has a script that makes it move but it just dont work

[rich adder]

nice CC pfp

[empty juniper]

thank you

[rich adder]

saw them recently

[short hazel]

Start debugging, place a log inside the if statement to ensure the code is running

[empty juniper]

im jelous

[late burrow]

no links just events

and on regular text component

[late burrow]

if i want only part of text to work for event i need make new component?

[swift crag]

no idea about the legacy Text component.

why not just use TextMeshPro?

[gray crest]

I've found where the lag spike happens, but how do i work out what script or object it is?

[tender stag]

do i need to include +1 at the end?

return UnityEngine.Random.Range((int)amount.x, (int)amount.y + 1);

[swift crag]

Vector2Int exists, btw

[tender stag]

if my number are like 1 and 3, it wont pick 3 if i dont add 1?

[swift crag]

and yes, if you want the range to be inclusive, add one to the upper bound

[tender stag]

whats that

i wont have to add 1 with that?

[swift crag]

no. it would, however, get rid of those (int) casts.

[tender stag]

oh alright

thanks

[fossil harness]

At the bottom it shows you a breakdown of function calls eating performance. Player Loop represents the game itself, within it the one you have highlighted is all FixedUpdates you have

The drop-down arrow on the left will show more details

Try to reprofile with deep profiling enabled

(click the button at the top)

Shift the marker in the timeline around that little spike you're sitting on, see if there's any piece of code that's is ramping up or something

[gray crest]

Thanks, i got 16% RenderCameraStack, is that an issue?

[crisp pollen]

Hey,
Is there a way to store multiple Vector2Int's in one List but in a List in a List.
So i want to save the positions of the Tiles from the Rooms in my game in a list but want all rooms have a own list so i can edit them later on per room and not general. So is there any way to save all Vector2Int's in one List but just Seperated.
Hope you guys understand what i mean

[polar acorn]

Like a List<List<Vector2Int>>?

[crisp pollen]

Yea ty i was kinda lost sorry for the question xD

[eternal needle]

it does sound like you want some class (room) to hold the list of vector2int, then another object would hold a List<Room>. If you do it this way, its a little easier to separate what a room is but would basically be a List<List<Vector2Int>>. the room class can hold extra functionality if needed too

[tender stag]

instead of doing this```cs
FuelProcess fuelProcess = fuelItem.GetProcess(ProcessData.ProcessType.Fuel) as FuelProcess;
foreach(var outcome in fuelProcess.processOutcomes)
{

} how can i make it one line like below?cs
foreach(var outcome in fuelItem.GetProcess(ProcessData.ProcessType.Fuel).processOutcomes)
{

}```

this is GetProcess method```cs
public ProcessData GetProcess(ProcessData.ProcessType processType)
{
foreach(var processData in itemData.processDatas)
{
if(processData.processType == processType)
{
return processData;
}
}

return null;

}```

i need GetProcess to return as the process

so that i dont need to add as FuelProcess; or as CookProcess; or as SmeltProcess; and so on

[timber pelican]

any advice on how I can make a snake like boss? I started out by separating the head and body sprits.
Anyone know of a tutorial that can help maybe?

[zealous oxide]

https://hastebin.com/share/tamamekefe.csharp i'm trying to adjust/use/make a turret script to find the closest enemy projectile within circle collider 2d but it never seems to find any projectiles, consequently the rest of the script doesnt progress. the turret never turns. i've tried to set the list as public to see if it comes up with any results but if i make the object and list public, it gives me the error in the first screenshot. now I think the issue may stem in the second screenshot, I dont understand how the script is meant to be giving a component to a object within its circle collider? is it meant to be working as some kind of mark/tag? the script i'm using/adapting is at the bottom of here https://gamedevacademy.org/tower-defense-tower-unity-tutorial/ ultimately i'd like turret to fire a shader graph made laser on the cool down on the closest target but i've not gotten around to making that half of the script#

[timber tide]

Why is your IDE greying out unity's methods there

You sure they are being called?

[zealous oxide]

this debug message appears in the console but i then get an error message that "curProjectile" has no object assigned

[polar acorn]

Where do you assign curProjectile

[rich adder]

debug means that it reached that line, you aren't even debugging curProjectile

[polar acorn]

And can GetProjectile return null?

[summer stump]

You should debug the curProjectilesInRange.Count

[timber tide]

Connect your IDE to unity and throw some break points around

[zealous oxide]

I think my IDE is already set up, has been for a while now

[rich adder]

put breakpoints in GetProjectile and debug/inspect your count or the returned projectiles

[summer stump]

They don't mean set it up. They mean use a feature of it.
Breakpoints and the debugger.
In VisualStudio, it should say "Attach to Unity" at the top, near the middle.

I also recommend that

[zealous oxide]

i've clicked attach to unity and im unsure what im meant to do from here

[polar acorn]

https://www.youtube.com/watch?v=d0815qbx3BA

[steep crown]

alt f4

[timber tide]

That's it. Now run it in the editor

You can also attach it if your program is already running which is nice AND be able to set new break points as it's running

[rich adder]

well make sure you got some actual breakpoints lol

[zealous oxide]

ok, going through this bit by bit, i want to debug log count the list of "curProjectilesInRange" but what I thought would be the right debug log message for it doesnt seem to work : Debug.Log("Projectiles Found" + curProjectilesInRange.Count.ToString());

[timber tide]

You sure your code is reaching them? Make sure that your code flows through first because sometimes it may not print if you have errors beforehand.

[queen adder]

i want this object to disactivate it self when touching the player and activate after a few seconds

but it never activate itself again

why is that??

[polar acorn]

When an object is destroyed or disabled all coroutines running on it stop

[queen adder]

so how to fix this?

[polar acorn]

Don't run the coroutine on the object that's going to be disabled

[queen adder]

ig this would kinda fix it

[tender stag]

anyone know why my colors randomly dissepeared?

like the class used to be red

and most items arent in color anymore

[polar acorn]

Are you using VSCode?

[tender stag]

yup

[polar acorn]

Yeah it does that

[tender stag]

any way to fix it?

[polar acorn]

¯_(ツ)_/¯

I'd suggest just using VS

[tender stag]

but themeeesss

can u get themes on vs?

[summer stump]

Yes

[tender stag]

what about the like smooth typing and that

like smooth scrolling

[summer stump]

But if you want. You can try regenerating the project files first

[timber tide]

I actually been liking vscode

[summer stump]

VS can do everything vs code can do, but also more

[tender stag]

oh

i didnt know that

[timber tide]

because between vs and unity, they both like to just freeze up and idle for hours and that's more than I can handle

[ruby elk]

Has anyone ever experienced when you instantiate an object it automatically turns the triggers in its colliders off?

[rich adder]

no

[tender stag]

maybe the object you are instantiating already has its colliders off

[ruby elk]

I've like quadruple checked everything

[rich adder]

like what?

[polar acorn]

Show code

[ruby elk]

The prefabs colliders, my code that instantiates it, my codes within the prefab

Of which SummonEnemy is called by a button

[polar acorn]

Okay, show the inspector for enemyPrefab

[ruby elk]

And the trigger is correct, 1 on, 1 off.

[polar acorn]

Okay, now show the inspector of the one that gets spawned

[ruby elk]

Sometimes it works sometimes it doesnt

This time it did

[polar acorn]

Keep going until it doesn't, keep the game running when you find it

[ruby elk]

Heres one that doesnt

[polar acorn]

Those colliders aren't disabled

[ruby elk]

The trigger is

its the trigger thats the problem. It needs to be enabled on the first collider

[polar acorn]

Triggers don't just toggle. Something you're doing is toggling it

So look for anywhere in code you're changing isTrigger of anything

[zealous oxide]

i've managed to add a breakpoint! its telling me theres zero projectiles in range, even tho they all have the "projectile" tag. i've added a load of text debug messages. whilst the projectiles are colliding with the circle2d collider, theyre not getting added to the list

[polar acorn]

That error looks like your problem

Seems ProjectileCurrent isn't a monobehaviour

[ruby elk]

I found a bit of code on a different object that had the same purpose of the one on the prefab, but had isTrigger. That should fix it, thanks

[zealous oxide]

so i need to have a component (could be a script) in the object titled "ProjectileCurrent"?

[polar acorn]

The things you get with GetComponent have to be Components

[zealous oxide]

"ProjectileCurrent" i believe is an internal class? and on trigger enter this component is being assigned to any projectile within the 2d circle collider? or is that not how its working

[polar acorn]

Show the code for ProjectileCurrent

[zealous oxide]

its at the bottom of that screenshot?

[polar acorn]

Ah, didn't see that

So that is definitely not a component

[zealous oxide]

np!

[polar acorn]

So GetComponent isn't going to get it

because it's not a component

[violet topaz]

how do i attach a camera to a player when loading a new scene

[polar acorn]

Depends on what you mean by "attach"

[violet topaz]

\

[polar acorn]

It doesn't look like you have any DontDestroyOnLoads or additive scene loadings you just didn't assign a camera

This has nothing to do with the scene changing

[wary sable]

would someone be able to explain why these two aren't the same?
(null ref exception when the latter is run)
gameObject.transform.Find("Item").GetComponent<Image>().sprite = item.Icon;

icon.sprite = item.Icon;
where

icon = gameObject.transform.Find("Item").GetComponent<Image>();```

it doesnt really matter, its just something that I stumbled into while trying to make some code look nice and cant figure out why

[rich adder]

one is setting a sprite to something , the other just grabs the Image component from something

[wary sable]

sorry the message is formatted weird, the first code block is the two lines that I am comparing, and the second block is context for the 2nd item in the first block

I tried to adjust it so its a bit easier to read

[rich adder]

are they on different objects?

[wary sable]

same object

[rich adder]

careful with transform.find, it only looks for children objects name

[wary sable]

yeah, this is for a item slot that is instantiated when the inventory is opened

[rich adder]

can you show the entire error null ref

[wary sable]

yeah, just one sec I need to rewrite the code

[wary sable]

well after putting it back in it works just fine

[crisp pollen]

also which line is error

[crisp pollen]

Oh sorry the line "RoomPositionList[r].Add(position);"
So line 23 in GDL

[wary sable]

correct me if I'm wrong but you are trying to call an index of an empty list

[rich adder]

your current size for RoomsPositionList is 0 but you're trying to modify 1 ?

ohh wait this is a list of list

[crisp pollen]

Okay but how could i change it than with code? Because a List<List<T>> will not get shown in the Inspetor and as is know it should work beause its a List of an List

[neon wedge]

does anyone know what im doing wrong?

[rich adder]

not sure what you're going for you can probably do RoomsPositionList = new(roomsList.Count);

[crisp pollen]

Yea i also thought about this the problem is that RoomsList is and BoundsInt and i need it in Vector2Int so i can place items later on

[crisp pollen]

Could you copy the hole script in one of these?

but you only want a size from it?

[neon wedge]

what do i do after i copy it?

[crisp pollen]

Copy the Link and send it in here but first save it

[crisp pollen]

No i place the Tiles in the positions and than i want later on place random object of some of these positions this is why i need it in a List<List> because there should be diffrent types of Rooms

[neon wedge]

https://gdl.space/garaxajaji.cs

Btw you can also do this like so

[Serializable]
public struct ListOfList

    public List<ListOfList> rooms = new();
}

[crisp pollen]

Try this
function = gameObject.GetComponent<PlayerMovement>();

[crisp pollen]

i will try it one sec

[rich adder]

get them to configure their IDE first

its in the #854851968446365696

[neon wedge]

i alr tried to configure it but it doesnt work

[rich adder]

what did you try exactly, b specific ? wdym doesn't work cause it does for everyone lese

[rich adder]

the VSCode one?

[crisp pollen]

Should this get shown in the Inspector?

[rich adder]

it should

actually no don't use that , that will just make clones of same list

yes

[crisp pollen]

oh okay

You got the Unity extension from Microsoft in VS Code
and
the Visual Studio Editor package (not VS Code Editor) in the Unity package manager?

How can i now add in such a list things bc now i get the error error CS1061: 'ListOfList' does not contain a definition for 'Add' and no accessible extension method 'Add' accepting a first argument of type 'ListOfList' could be found (are you missing a using directive or an assembly reference?

[neon wedge]

i dont understand

[summer stump]

What part? Those are the things the IDE guide tells you to do
They are required for it to work

[neon wedge]

how do i doownload the package

[summer stump]

Go to unity's package manager

Within unity, in the Window menu

[neon wedge]

and?

[summer stump]

And what? Get the package I said.

Visual Studio Editor version 2.0.21

I'm working on an FPS controller. I'm using the new input system and cinemachine. I'm noticing that when I move the mouse when I reach the edge of the screen I can't move the mouse any more in that direction so I can't rotate the view any more. Not sure if it matters but my curser is visible. I'm also using Mouse (Delta) for the mouse look input. How do I get it so I keep getting Mouse (Delta) values even if the mouse can't move any more on the screen?

[wintry quarry]

You should lock your cursor

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

[neon wedge]

i alr have it downloaded

but i use vs code not vs

That was it, thanks!

Is there any way to see a List<List<T>> in the Inspector?

[rich adder]

this is the way lol

is this what im supposed to be seeing?

oh haha

[summer stump]

@neon wedge No, MonoBehaviour and those other types should be a different color as far as I know...

[crisp pollen]

How could i remove all stats?

[rich adder]

wdym by "stats"

[crisp pollen]

Remove everything out of the ist

[rich adder]

list1.MyList.Clear() //clears one list
or
rooms.Clear() //clears all
ofc just like adding you can also use indexes of list
rooms[0].MyList.Clear();

[crisp pollen]

ty

[neon wedge]

can u hel me fix the error tho?

[rich adder]

hope that clears up a little 😅

[rich adder]

did you fix your IDE? or else you will come back later with another syntax error

[crisp pollen]

Yea just one last question can i normaly check them so like "rooms[1]"?

[neon wedge]

ye i think i fixed it

[rich adder]

like rooms[1].MyList.Count

or w/e else

[summer stump]

I don't even know what the error was 😂

[rich adder]

you always wanna check count before doing index

[crisp pollen]

Ty you realy helped me

[rich adder]

they fixed first syntax error but has an NRE
#💻┃code-beginner message

[summer stump]

https://unity.huh.how/runtime-exceptions/nullreferenceexception

[rich adder]

oh also using class instead of instance

[neon wedge]

https://gdl.space/unapipipeg.cs

[neon wedge]

how do i use it?

[wintry quarry]

PlayerMovement.grounded == false < why are you using PlayerMovement here before the .? That's the class itself.

[rich adder]

oh wait second error is not NRE

[summer stump]

Shows you how to understand and diagnose nullreferenceexceptions

[rich adder]

its Input class missing"jump" ig class is missing Jump() method being defined

[summer stump]

OOP, I was led astray!

[rich adder]

myb

this whole line is redundant function = gameObject.GetComponent<PlayerMovement>();
function is already public, just drag the component inside script , its on the same object

[neon wedge]

i dont understand what you mean

[wintry quarry]

aand why is it called function? 😢

[neon wedge]

idk i just named it or smth

[wintry quarry]

you don't want to know if "the concept of PlayerMovement" is grounded. You want to know if the particular instance of that script that is attached to your player is grounded. Adjust your code as such

[wintry quarry]

do you even know what you are naming?

it's a reference to a particular instance of that script.

that's the thing you should be interacting with.

[rich adder]

^^ name should be clear what component it is you're using

if class is called PlayerMovement then ideally you would just name it playerMovement instead of function

[wintry quarry]

or player or anything reasonable

[lunar root]

Hi! I am trying to make some walking and idle animations, but I don’t know how I can make it so that the player idle animation faces in the direction it was last moving in.

[rich adder]

2d or 3D ?

[lunar root]

2d

It’s a simple 2d top down game.

[rich adder]

how are you currently rotating player? do you have script you can share

[lunar root]

Yes, I do. But let me get it first.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.InputSystem;

public class PlayerController : MonoBehaviour
{
    Vector2 movement;
    public float moveSpeed = 5f;
    public Rigidbody2D rb;
    public Animator animator;

    private void Update()
    {
        movement.x = Input.GetAxisRaw("Horizontal");
        movement.y = Input.GetAxisRaw("Vertical");

        animator.SetFloat("Horizontal", movement.x);
        animator.SetFloat("Vertical", movement.y);
        animator.SetFloat("Speed", movement.sqrMagnitude);
    }

    private void FixedUpdate()
    {
        rb.MovePosition(rb.position + movement.normalized * moveSpeed * Time.fixedDeltaTime);
    }
}

This rotates the player to wherever it's moving.

[crisp pollen]

hey sorry to bother you again..
But how could i now get a Vector2Int out of it for example i want now a random Vector2Int

[rich adder]

ohh you're using a blend tree or something?

[lunar root]

Yep

Should I be changing my method?

[rich adder]

int randomIndexOfRoom = rooms[0].MyList.Count;
Vector2Int randomCoordinate = rooms[0].MyList[randomIndexOfRoom];```

you can do the same thing for rooms ofc

[lunar root]

Are blend trees not good for this?

[rich adder]

i guess you could modify the floats only if you're moving

if(movement != Vector2.zero) { anim.SetFloat etc..

[lunar root]

Ok

I will try this

[lunar root]

Thank you so much, the player now faces in the correct direction, and all I have to do is make the idle animations. I do have to go now, but thank you for the help.

[wary sable]

unity is giving me a warning when writing an awake method for a button class?
'EquipmentSlot.Awake()' hides inherited member 'Selectable.Awake()'. To make the current member override that implementation, add the override keyword. Otherwise add the new keyword.

Button inherits from mono so using Awake the same way as a mono script shouldn't be problem?

[summer stump]

EquipmentSlot inherits from Selectable, and then THAT inherits from MonoBehaviour? Can you show the code of the two classes?

[wary sable]

selectable is a unity script

https://docs.unity3d.com/2018.2/Documentation/ScriptReference/UI.Button.html

which according to the docs none of the children override Awake so idk

[summer stump]

I think that it is not quite the same as a MonoBehaviour Awake. Try just doing override and using base.Awake()

[wary sable]

I mean I can but

[summer stump]

Yeah, I saw that.

[frosty hound]

Your parent Selectable class needs to be protected virtual void Awake(){} and so your child EquipmentSlot class can:

protected override void Awake()
{
  base.Awake();
  // Additional things this child class does
}

[wary sable]

thanks!

[sacred zenith]

Hi, given this line Debug.Log(wheel_velocity_LS + " -> " + wheel_velocity_LS.x + " == " + Vector3.Dot(wheel_velocity_LS, transform.right));
In my basic knowledge of vectors, wheel_velocity_LS.x and Vector3.Dot(wheel_velocity_LS, transform.right) should be the same value, however I am getting this:
(5.01, 0.34, 26.74) -> 5.01121 == 13.19427

Can someone explain to me whats going on please?

[summer stump]

The formula for dot product is easy. Given Vector3 A and Vector3 B, it's just ((A.x * B.x) + (A.y * B.y) + (A.z * B.z))

You should log the transform.right vector and see what it comes up as and just do the math to understand more fully

I would expect it to ONLY be the same if the transform.right vector lines up perfectly with the Vector3.right WORLD vector (thus zeroing out y and z)

[sacred zenith]

Makes sense, thank you
