#

Then you've got multiple copies of this script that are all running their click code

#

Because you've got multiple logs saying they've detected clicks

ashen frigate
#

im using player input manager but i dont think thats the problem

polar acorn
#

It demonstrably is your problem. If you're clicking one time, then your screenshot proves this is the case

#

You're getting multiple logs stating the click was detected

#

so there's multiple things running that line

ashen frigate
#

would holding the button affects it ?

polar acorn
#

No idea. Depends on what getClicked does on NewVirtualMouse

ashen frigate
#

its a new playerinput unity

#

so if i hold it it stay true i think

polar acorn
#

Unity has no components named NewVirtualMouse so I literally cannot know what that function does

#

How about replacing the log with a better one:

Debug.Log($"{gameObject.name} has detected Mouse clicked", this);
ashen frigate
#

no need

#

i hold press it and got jambo log

#

so its a hold problem probbly

#

`public void OnClick(InputAction.CallbackContext context)
{
Clicked = context.ReadValue<bool>();
//Clicked = context.action.triggered;

if (Clicked)
    Child.GetComponent<Image>().sprite = clickCursor; // שינוי תמונת ה-Child
else
    Child.GetComponent<Image`

is it readvalue for 1 press ?

public void Heal(float value) => CurrentHP = Mathf.Min(CurrentHP + value, MaxHP) if it's of any help, this is how I have my own healing code that makes sure it never exceeds the max value

#

Mathf.Min will return whatever is smaller, so if given (125,100) it would return 100

#

the Min and Max functions are quite helpful for logic like this

#

I think part of the problem youre having is while (health < Maxhealth). If health = 100 and MaxHealth = 100, then the condition will enter because health is not actually less than the max

#

health gets to 100, then heals by 25, and only now will that condition no longer be met

sterile radish
#

yes, i changed the line but the issue still seems to be occurring. its hard to describe but even on the first loop of the while loop the health gets set to 125 and im not sure how, the health should just be 25 if that makes sense?

cosmic dagger
sterile radish

#

oh sorry its the same code it just copy and pasted weird idk why

#

i see what you mean now

cosmic dagger
#

I think the issue is that tile.Heal() runs multiple times. In Update you check if its health < 0, but the coroutine doesn't add 25 until after 2 seconds. Update runs every frame, so . . .

sterile radish
#

yes, i think that seems to be the issue ive been trying to avoid. i think ill just seperate my logic form the update loop completely. thank you for the advice!

#

if I disable an object via script, then reactivate it, will the scripts inherited to the object come back working too or not?

cosmic dagger
#

Scripts aren't inherited to GameObjects (that was my confusion). They are separate components attached to a GameObject . . .

#

Basically, a GameObject is a container storing a list of components; that's it.

okay thank you, i see it now

misty meteor
#

ok i am having an issue. i got this script to turn on and off my flashlight. i also have a script on my player to not destroy my player nor flashlight. my flashlight will work in the first scene, turning on and off. but when going to my second scene my flashlight is still on my player but the script to turn it on and off no longer works

#

first scene it works

#

how do i fix?

Strike three, you're OUT!

so how do i adda cooldown to a hitsound?

rich adder
#

switch it to a coroutine? or make a timer in Update

cosmic dagger
verbal dome
# misty meteor

How are you preventing them from being destroyed? DDOL?
Is the flashlight a child of the player? What object is the ToggleLight script on, what does your hierarchy look like?

vivid cedar
misty meteor
#

the flashlight and script are both childs of the player

#

which is weird because the flashlight stays and so does the script

#

but the script no longer works??

cosmic dagger
rich adder
misty meteor
#

ToggleLight is attached to the flashlight, which is a child of the player

#

which the ddol script is attached to

verbal dome
#

And LightSource is a child of the flashlight?

misty meteor
#

yep

cosmic dagger
misty meteor
#

okay i just fixed it actually. so apparently the flashlight script was working but I just needed to move the light forwards a bit because it was stuck in the flashlight?? but it worked in the first scene...

#

thank you though haha @cosmic dagger @verbal dome

#

i was stuck for like 20 minutes

#

how does this seem for organized bits of an IInteractable setup

cosmic dagger
# rocky canyon

I would swap IStateInteractable to IInteractableState and change IInteractionList because you're not storing an actual list but an array. You can use Collection, Group, or Set instead . . .

IInteractableCollection : IInteractable
IInteractableGroup : IInteractable
IInteractableSet : IInteractable

does sound better.. 1 sec let me get this switch script saved and in tested

how do you make a class singleton

then u can simply use : Singleton<YourScript>

i wanted to save all the things that changed in my scene during gameplay so i thought id use loadscenemode.additive to load the minigames

#

however the scenes intercept eachover so it becomes a mess

polar acorn
#

Yeah, that's what additive scene loading is, it adds the new scene to the current one

lament harness
#

so i have to make the static class singleton somewhere
and then I can use it?

molten dock
#

yes, so what should i be doing instead

timber tide
#

do you care for deloading the previous scene

#

if not, just disable it

molten dock
#

i can disable the scene?

timber tide
#

Well, disable components of the scene that would be causing problems, because why would you use additive in the first place if you wanted to remove everything

molten dock
#

if i could set the scene to inactive then it would keep all the changed stuff the same for when i want it

timber tide
#

Not sure if you can just deactive a scene as is, so you may need to throw everything into an empty mono behaviour and deactive that

astral falcon
#

I wonder what you wanna save in playmode that you dont have access too in edit mode. Values on a script?

molten dock
#

removed objects need to stay removed and values need to be kept

astral falcon
#

So you are doing your level setup in playmode or what exactly?

molten dock
#

the player can pick up objects which then get removed from the scene

tawdry rock
#

Anyone know how can i access this RectTransform option via code? (when you press left alt to stretch)

polar acorn
tawdry rock
#

i tried something like .GetComponent<RectTransform>().anchorMin = new Vector2(1f, 1f);

#

nothing happened tho

astral falcon
polar acorn
#

Once you change the anchors, you'll need to also change the anchoredPositions

polar acorn
molten dock
#

when i load a scene for a minigame and then leave the minigame the original scene is then restarted

astral falcon
astral falcon
polar acorn
#

This is assuming you have no functionality that depends on OnEnable or OnDisable

molten dock
#

I have decided to include the mini games in the main scene as under a parent object each

molten dock
polar acorn
# molten dock I did think of that but don’t know how I will re activate the map afterward

Objects that are disabled can still run functions you've defined. You can have whatever object is supposed to change back to that scene reference it and re-enable it. You'll need some way of getting a reference to it, probably the easiest way would be to make it a singleton, but that assumes there will only ever be exactly one scene that needs to be "paused" this way

cerulean badger
#

when I use "this" in the script it returns the object as a GameObject or Transform?

polar acorn
#

It returns the script

So, ive been trying for a while to make my player be able to jump only when he is grounded. Now this code works on another map that I have tried but for some reason doesnt work on another one. Ive used debug logic to figure out that the issue is that i am not being considered "grounded" when I should be i have tried adjusting player settings, tweaking the way detection for being grounded works but nothing is working. I also made sure that the layer mask of "whatIsGround" is applied. Would really like some help on this issue:

Before your grounded raycast, add this snippet:

foreach(RaycastHit hit in Physics.RaycastAll(transform.position, Vector3.down, PlayerHeight * 0.5f + 0.2f)){
  Debug.Log($"Raycast detects object {hit.gameObject.name} with layer {LayerMask.LayerToName(hit.gameObject.layer)}, Passes mask? {whatIsGround == (whatIsGround| (1 << hit.gameObject.layer))}");
}

It's going to absolutely spam the console, so you might want to turn on Collapse if it's not already on

polar acorn
#

Any time this object stops contacting an object tagged "Floor" it will fire that condition

modest linden
#

So i try walking in the game and and i start falling in the map

wanton epoch

alright

#

Assets\Scripts\PlayerMovement.cs(46,188): error CS1061: 'Collider' does not contain a definition for 'layer' and no accessible extension method 'layer' accepting a first argument of type 'Collider' could be found (are you missing a using directive or an assembly reference?)

polar acorn
#

bah, never code without an IDE kids. .collider.gameObject.layer for those

modest linden
#

Because it has a PlayerMovment script

polar acorn
#

PlayerMovement is a pretty common thing to name a script that moves a player

modest linden
wanton epoch
#

So i just tried it and im not getting any debug logs. just to make sure, this is the line I wrote:

foreach (RaycastHit hit in Physics.RaycastAll(transform.position, Vector3.down, PlayerHeight * 0.5f + 0.2f))
        {
            Debug.Log($"Raycast detects object {hit.collider.name} with layer {LayerMask.LayerToName(hit.collider.gameObject.layer)}, Passes mask? {whatIsGround == (whatIsGround| (1 << hit.collider.gameObject.layer))}");
        }

does canvas object covering entirety of other objects turn them inactive?

#

Regardless of layer

wanton epoch

polar acorn

Is there any way to visualize a raycast?

I checked btw, if im free falling, I get this log|

but nothing if I am on something. even a new p[lane

polar acorn
polar acorn

you mean like creating a new layer mask just for the player? and making the raycast hit that instead of my ground later?

wanton epoch

Is playerHeight the value you think it is?

wanton epoch
#

ill try and figure out this Draw Ray thing

wanton epoch
#

im sorry ill try again

#

bruh i think i fixed it

#

my player height was too low.....

For some reason, it needs to be at lesat 2.8

but on another map, I can go as low as 0.5

Im making a turn based combat system and I currently have a function that activates a skill (which is a scriptable object that SkillScriptableObjects controls the data from) If i want to have multiple skill slots instead of 1, how should i go about making it? Do i make a class that stores all the ui elements and the Skill? Here is what im using right now ```cs

public TextMeshProUGUI descriptionText;
public Image attackIcon;
public TextMeshProUGUI mpText;
public TextMeshProUGUI healthText;``` ```cs

public void onSkill(BattleStateManager battle)
{
    bool noMp = StartBattleSpawns.playerUnit.TakeMp(skill.mpCost, battle);

    if (!noMp) 
    {
        Debug.Log("Not enough MP to use the skill!");
        return; 
    }

    bool isDead = StartBattleSpawns.enemyUnit.TakeDamage(skill.attack);
    battle.hpSlider2.value = StartBattleSpawns.enemyUnit.currentHp;
    battle.playerMp.text = StartBattleSpawns.playerUnit.currentMp.ToString();
    battle.mpSlider1.value = StartBattleSpawns.playerUnit.currentMp;

Here's a crude idea
short meadow
#

Hello! It's my first time trying to use UI to pause a game. I have a small game for a jam a guy and I put together and I'm trying to get the menu working.

I have a UIManager empty with this script attached: https://pastebin.com/HED8sJcQ

I've assigned everything in editor. The game is just supposed to sit in the background paused until the person hits play basically. I can hover over my button to see it but clicking doesn't do anything. (It actually makes my character attack in the background).

The game starts in the background before you click play and my Debug.Log in ShowStartScreen isn't ever printing.

I'm not sure what I'm doing wrong here, any help would be greatly appreciated.

# rain ginkgo what is it asking for?

For next time, you have to wrap InteractableObj in typeof() so it uses the type correctly. Even better would be to use the generic type.

TryGetComponent<InteractableObj>(out info);

Considering it can also fetch the type from info since it's predefined, the solution of Mao also works.

Your update loops are effectively frozen there, so any input polling will not be received

short meadow
#

I'm actually more confused now than I was when I posted because my start function isn't being called, and this is the only script I have that attempts to set timescale so it shouldn't be paused anywhere else even if it affects UI.

timber tide
#

Buttons linked to methods like that should probably still be called, but maybe I'm blind but I'm not seeing any here

#

Oh yeah I see them

#

Yeah those should still work

#

I'm actually not sure if start will be called if it's scaled at 0 on instantiation

#

Start is called on the first update of the script

short meadow
#

I had a variable reference to an unimplemented screen tutorialScreen. I commented it out and the line in ShowStartScreen(); and it's working now.

I had no warnings, errors or anything. I didn't realize an unassigned reference in editor could break your script like that. Wild.

I THINK it's solved for now though at least. -2 hours lol. At least I'll remember this 🤷 next time.

astral falcon
#

Because every null error will break your entire runtime execution. Thats just how it is. So either be sure its there or check for null and skip accessing it if its null to avoid breaking your runtime

short meadow
#

I super appreciate that explanation though. It's good to have it put into words.

astral falcon
#

Not calling out, just pointing out facts, that you might have missed a step in debugging it and therefore I gave the explanation what happens when accessing the refrence not set. Sorry, if that sounded harsh for you, wasnt meant to . I am just a fan of clear words to describe 😄

#

When should I create manager classes? For example should I create MovementManager, AttackManager, TurnManager, ItemManager, if I'm doing a turn based game?

chrome apex
#

So, when modifying scale for a sprite, I can't make it tile with the transform component? I need to actually get and modify the ''spize'' component in the sprite renderer?

grand snow
chrome apex
#

using scale doesn't tile it

#

it just streches it

#

I just modify the sprite renderer.size instead and it works

If your code has allot of if statements, or logic you dont want to get checked every frame

Though if its a very simple system then it doesnt matter

On another note, I want to rotate a sprite between two mouse click such that the ends of the sprite are between the clicks

hexed terrace
#

Define "disappears"

Destroyed or just moves out of view of the camera?

#

Also, if you're working with 2D, you usually don't want to move on the Z pos (in / out of the screen)

#

2D moves on x/y

tulip nimbus
hexed terrace
#

I haven't made anything 2D .. but I assume Z pos is pretty much ignored

slender nymph
#

it's used for sorting and depth. and if things get too close to the camera or behind its position then it won't render those objects

plane draw distance, same as 3d

thought sorting was done with the layer field on the sprite renderer

how can this cause this error

here is the whole bit if that matters:

#

item is null there

hexed terrace
#

image or item is null

slender nymph
#

image is null in the else statement too so no matter what it's going to throw

rancid tinsel
#

ahh

#

that makes so much more sense

#

i got tunnel visioned on the image part

hexed terrace
#

I had only looked at the first screenshot

rancid tinsel
#

wait no but that cant be right

#

let me send the whole method

slender nymph
#

it's the only explanation so it is right

hexed terrace
#

prove it to yourself and log it

rancid tinsel
#

!code

eternal falconBOT
rancid tinsel
hexed terrace
#

Debug.Log($"item is null {item == null}");

rancid tinsel
#

so if item is null it cant run

slender nymph
hexed terrace
#

itemList can have empty (null) elements

rancid tinsel
#

oh does it not throw it if the object itself is null?

slender nymph
#

it only throws if you try to access something on a null object. you can pass null around all you want, but as soon as you try to get something from that null object it will throw

rancid tinsel
#

i see, thank you! ill add a null check and return from the list method then

oh no i just did that for a breakpoint

its just that, for some reason the assigned value of a gameobject.... doesnt assign properly?

hey guys new here just wanted to know why my dash only happens once every 3 or so console prints

do you plan on providing context?

did you actually save the code? because it's unsaved in your screenshot

# slender nymph do you plan on providing context?

sorry for that, i made a dash script with a coroutine and then called it to a player controller. this is vector 2d with 8 directional movement. i did a print on the coroutine and the code works fine, but the actual dash only happens once every 3 console prints

youre prob right ill take a look at that

this made the character dash once in 4 tries

and where do you call dashActive and have you actually done any debugging to find out the state of the variables you are checking to even start the coroutine

rancid tinsel
#

is this bad practice in any way? was getting annoying ondestroy errors in unity when quitting playmode

image.png
#

the Application.isFocused made the errors go away unlike Application.isPlaying

burnt vapor
#

So this creates an edge case

#

That said, XY problem, why do you have these problems to begin with?

rancid tinsel
#

It's not really a problem, it's just that it's a team project and I don't want someone to look for a "false" error

#

I don't understand why there is no option to ignore closing playmode on OnDestroys to begin with

iron wind
#

That sounds more like a problem with your code than OnDestroy

#

What exactly are you trying to do that warrants some OnDestroy not being called when the object is destroyed?

rancid tinsel
#

it is meant to be called when its destroyed

#

while the game is running

#

not when it closes in the editor

iron wind
#

but closing the game in the editor is also destroying all your objects

#

since you are effectively "closing" the game

rancid tinsel
#

sure. but what is the point of that behaviour? what is the use case for OnDestroy triggering when the game shuts down

#

it feels counterintuitive

iron wind
#

OnDestroy triggers when the scene the object belongs to is closed

#

Closing the game down completely also triggers that since you are unloading the scene

rancid tinsel
#

i know

iron wind
#

I don't see how that's counter intutive is what i mean

rancid tinsel
#

OnDestroy -> when you destroy this object, do ...

#

Calling the function you use for in-game stuff when closing the game is weird

#

why not separate the two

#

unless there is something else that works just like OnDestroy that i dont know about

drowsy wraith
#

Application.isPlaying no?

#

instead of isFocused

rancid tinsel
#

that doesnt work

#

i tried it

drowsy wraith
#

So you don't want it to show as you're working on it with other people and they might get confused ?

iron wind
#

maybe you are looking for OnDisable

rancid tinsel
#

essentially yeah, i can also put a comment in but why would Unity throw an error

rancid tinsel
runic lance
#

what is the error by the way?

iron wind
#

yeah that's probably a better question

runic lance
#

I don't see why this behavior is not expected, when the scene is destroyed, the object is destroyed

#

doesn't really matter if the game is closing or not

iron wind
#

I'm guessing the error is that your PopulationManager.Instance is already destroyed

rancid tinsel
#

"Some objects were not cleaned up when closing the scene. (Did you spawn new GameObjects from OnDestroy?)"

#

and it refers to the PopulationManager

runic lance
#

then most likely the instance was already destroyed and you're creating a new one, since it's a singleton

rancid tinsel
#

sure but my issue is - how else am I meant to call something when the object is destroyed

verbal dome
rancid tinsel
#

the error is caused because its a singleton and a new one gets generated if its destroyed but the method is called

runic lance
#

you can work around it by storing a reference to the singleton in the class that is being destroyed

verbal dome
runic lance
#

instead of accessing the Instance every time

rancid tinsel
#

how do i call something on when its destroyed though

iron wind
#

I think in this case you'd be better of adding/removing to population manager in OnEnable/OnDisable instead

rancid tinsel
#

the singleton doesnt matter

rancid tinsel
verbal dome
runic lance
#

he's already checking for null there

#

although incorrectly, since accesing the Instance property will always create a new one

verbal dome
#

If it's okay that its null, then sure

rancid tinsel
#

my issue isnt with the singleton behaviour

#

i dont want whats in OnDestroy to ever trigger on game close

#

idk if there is a different method for that

verbal dome
#

Btw Application.isQuitting exists, might be also helpful

runic lance
#

there isn't, when your game closes your scenes get destroyed and everything contained also gets destroyed

rancid tinsel
#

but the idea is, if the object is ever destroyed by whatever, decrease population size and remove it from population list

verbal dome
#

And when the whole game quits, you don't care about removing it from the population, correct?

rancid tinsel
rancid tinsel
#

i saw this mentioned elsewhere too

verbal dome
#

Oops, *Application.quitting

rancid tinsel
#

oh oops yeah

#

i made that mistake earlier too lol

verbal dome
#

(Weird naming convention from unity, usually their bools start with is)

runic lance
#

IMO the cleanest way to do this would be to store the singleton reference on Awake/Start and then check for null on OnDestroy

rancid tinsel
#

its an "action" it seems

verbal dome
#

Ah it's an event, right

#

I might have hallucinated

rancid tinsel
#

ok i seem to have found a solution

slender nymph
#

this doesn't seem necessary, what issue is this supposed to solve?

rancid tinsel
#

had some help from copilot, and thats what ive got after cleaning it up

rancid tinsel
slender nymph
#

what error

rancid tinsel
#

OnDestroy calls a singleton when game is quit

verbal dome
#

They were accessing an already destroyed singleton in OnDestroy
And accessing it would create it again, which is not allowed from OnDestroy

rancid tinsel
#

which creates a new instance

cerulean badger
#

what's the best option for handling multiple attacks inputs: the old Input class or the InputSystem thing?

slender nymph
rancid tinsel
#

i think the point of the automatic instance creation is for it to not cause errors if someone forgets to add it to the scene

#

the singleton solution we are using wasn't done by me, but a colleague

#

so I wouldn't want to mess with that

runic lance
#

but the issue is that automatic instance creation is not suitable there

#

most likely the issue would also show up if you unloaded the scene manually

verbal dome
rancid tinsel
verbal dome
#

Such as a property InstanceExists or a TryGetInstance method

verbal dome
rancid tinsel
#

either way its basically one case in which its bad, i think its better to just use OnApplicationQuit here

verbal dome
#

Nothing wrong with that IMO

rancid tinsel
#

different question though - how do static variables work? I assumed you couldn't change them at runtime, but clearly in the screenshot I sent that's what it's doing

slender nymph
#

you're thinking of const. static just means the member is not associated with any instance

rancid tinsel
night mural
# rancid tinsel

if you ever have any new entities like this, you'll have to remember to clean them up in the same way which feels fragile too

rancid tinsel
#

what does it mean in practice that its not associated with any instance? does it mean that if I change it, it changes it for every VikingTracker holder?

night mural
rancid tinsel
#

Assembly definitions are used to break your code into separate units.

Incorrectly set up asmdefs wouldn't completely break your IDE, though

Newly installed packages can't start doing anything until you resolve that

frigid sequoia

Before I get to it and totally waste my time; if I Lerp an object posstion, that does not trigger the trail right?

verbal dome
frigid sequoia
#

Yes

verbal dome
#

I don't know why it wouldn't trigger

#

The trail doesn't know/care if the position was lerped or changed in some other way

polar acorn
#

Lerp just gets a value some percentage of the way between two other values. It's not a different method of moving an object

#

It's just a way to compute a value

frigid sequoia
#

I thought trail just activates when you move the thing, not teleport it, which is what a Lerp possition would do

With transform, there's reaally no difference in "moving" and "teleporting"

Hey,

Is there a way to check the hitbox of a character midgame?

I mean cuz i added a meele attackbut i dont know how much large it is

Here's the script btw

# 
{
    Collider2D hitEnemy = Physics2D.OverlapCircle(transform.position, attackRange, demons);

    if (hitEnemy != null)
    {
        if (hitEnemy.TryGetComponent(out EnemyBase enemy))
        {
            enemy.TakeDamage(meleeDamage);
        }```

#

you can use the Gizmos class to draw the overlap circle, or use a convenient package like vertx's debugging to draw your physics queries (mostly) automatically

that option is only available when you have a CreateAssetMenu attribute on the class

why not just read the docs?

You can just search CreateAssetMenu on google

or even ScriptableObject because the example for that includes the usage of the attribute

I need the static class GameManager to exist right away. Is this the best way to do it?

GameManager.Init() literally does nothing but print "Game Manager is initialized". But I need to call it in order for the static constructor inside to execute its code at all.

verbal dome
slender nymph
#

there is no guarantee when a static constructor is going to be called except that it will always be called before any instance is constructor or any static member is accessed. if you need something to happen before everything else in a static context with no extra code, then use what Osmal suggested instead of relying on the static constructor to be called

fathom bramble
#

Honestly all I'm trying to do

#

is have a GameManager persist through every scene. Is using DontDestroyOnLoad() better for that? I just feel weird attaching a gamemanager to an object in a scene

#

but if that's better practice so be it

slender nymph
#

static constructors and DontDestroyOnLoad solve completely different issues. if you just want it to not be destroyed when you change scene, then yes all you need is to pass it to DontDestroyOnLoad

#

if you just want to spawn the object and mark it as DDOL any time you launch the game then use the attribute osmal linked to do that initialization

fathom bramble
#

The only reason I used a static constructor is that I want my GameManager to subscribe to events that I plan to fire (like a GameOver event)

With other gameobjects, I use Awake()

#

but since my game manager isn't a regular game object, I couldn't

#

but I guess it can be

slender nymph
#

it doesn't need to be. use the attribute that was suggested

fathom bramble
#

is it some preprocessor thing?

grand snow
#

Attributes!

Hey guys! Is there a way to detect if I have only clicked (and released) or if I'm holding the left click with the new unity input system?

    [SerializeField] private InputActionAsset PlayerControls;
    private InputAction shootAction;

    void Awake()
    {
        shootAction = PlayerControls.FindActionMap("Player").FindAction("Shoot");
        //shootAction.performed += _ => FireWeapon(); // When clicked
    }
#

Or do I have to do manually, like setting a variable isShooting to true when performed and to false when canceled?

rich adder
wintry quarry
#

Not events

#

The events will only tell you when something changes

rich adder
#

if you want hold behavior on button set it from Button to Any Value then you can use Started,Canceled to set a bool

proud escarp
timber tide
#

could also do a coroutine and cancel it when not holding and things like that but update is fine

wintry quarry
#

The new input system provides flexibility

#

Event based handling is just one option it offers

proud escarp
#

I thought it was something like an optimized way to handle performed actions, instead of checking them every frame in the update

#

I guess I'll do what's easier to understand for me now, like maybe a variable saving that state

wintry quarry
timber tide
#

I'd argue that it's not some extreme optimized solution from the older input system. It's cleaner and allows for quick key rebinds that's for sure

proud escarp
wintry quarry
#

The events are still being checked every frame

timber tide
#

I'd suggest just poll the input if you're not too aware of events if you want to get started on something

#

using the legacy input system

proud escarp
#

I understand, I thought there was some kind of optimization underneath lol but yeah it surely make the handling more cleaner

wintry quarry
#

Performance was never the concern

btw I'm looking inside the InputAction class, and I'm finding some events which would maybe help on that

Hey! It's my first time using the whole get; set; thing and I'm a bit lost on what's the proper syntax for what I'm trying to do. I've read the debug errors and I think I get the gist but I'm still lost.

image.png
slender nymph
#

you've redeclared the maxHP variable as a local variable inside of the setter but also it's after you attempt to use it

#

remove that extra declaration, make sure to return maxHP in your getter too
oh and your property (which is what you referred to as "the whole get; set; thing") is private

guys can someone help please

This thing results file being created like normal in Editor
But in builds it creates file with 0 bytes

#

i did log how many bytes i download, its not 0

naive pawn
slender nymph
#

oh yeah that too, completely slipped my mind lmao

tulip stag
slender nymph
#

your assignment is backwards too, but yes

tulip stag
slender nymph
#

or wait no this whole setup is confusing because you don't seem to understand how properties work

tulip stag
#

I don't :P It's my first time using them. I've read the documentation but I'm still lost

slender nymph
#

you need to declare a field to store the value of your currentHP because the property itself doesn't hold the value, the backing field does

tulip stag
#

What I'm trying to achieve is simple: when I write into currentHP, make sure it never exceeds maxHP

tulip stag
grand snow
#

I feel like a function is easier to start with instead of a property

tulip stag
#

IS THAT SO?

slender nymph
#

yes, properties are basically just methods that look like variables

tulip stag
#

if that's the case I'm cooked— I've been {get; set;} damn near every variable in the entire project

hot laurel
#

thats just syntatic sugar for 2 methods(getter and setter) with backing field

deft siren
#

i tried doing this simple lightswitch code but for some reason it doesnt work, the icon appears so it its conisdering itself inside the trigger but when i press E nothing happens

image.png
grand snow
#

thats an exception. {get; set;} makes the backing field for you internally by magic

slender nymph
tulip stag
#

This is what the average class in my code is looking like

image.png
slender nymph
#

those are all auto properties which means the compiler creates the backing field for you

rich adder
hot laurel
#

well those properties set and get have empty bodies, why not to use just public fields then

slender nymph
#

most of them are likely from the interface which requires using properties because interfaces cannot have fields

tulip stag
slender nymph
polar acorn
tulip stag
grand snow
#

I would do:

public int HP
{
    get => _hp;
    set => _hp = Math.Min(value, maxHP);
}

private int _hp;
private int maxHP;
tulip stag
#

Something else that's been puzzling me is this compiling error in particular.

image.png
slender nymph
# tulip stag Mhm, that's partially it. For the others, it's simply because I've been told it'...

that is for sure the way to go about it, you just need to understand how properties actually work.
I don't normally do this because i hate spoon feeding, but this will explain how you should structure your property (also i will be using proper name conventions rather than what you are using):

[SerializeField] private int _maxHP; // this is obviously the field you are using to validate the property's max value
private int _currentHP; // this is the explicit backing field, in other words this field is what is actually holding the value that is returned by the getter for the following property
public int CurrentHP // property declaration

  get => _currentHP; // you have to return the value of the backing field in the getter to provide the correct value when getting the property
  set => _currentHP = Mathf.Clamp(value, 0, _maxHP); // this assigns to the backing field using the `value` keyword which is what contains the value being assigned to the property, i've used Clamp here to make this shorter since you probably don't want it below 0 anyway

So, my only question right now is: Now that I have a backing field and a property with Get; Set;, how do I interact with this in other parts of my code? Let's say I need a function that displays my HP. Which one do I call, the backing or the property?

rich adder
#

ideally the property that should be Get public only

#

one of the main benefit of props is to give write access to its own script while keeping outside scripts on a Read only requirement

#

if you have extra logic to run in the Property then always grab/set the prop if its Get or Set

#

normally your backing field is only there to set values within its own class

tulip stag
# 
        int maxHP;
        int tempMaxHP;
        bool hasTempMaxHP;
        int tempHP;
        int _currentHP;
        int currentHP
        {
            get
            {
                return _currentHP;
            }
            set
            {
                if (tempMaxHP > 0)
                {
                    if (value > maxHP + tempMaxHP)
                    {
                        _currentHP = maxHP + tempMaxHP;
                    }
                }
                else
                if (value > maxHP)
                {
                    _currentHP = maxHP;
                }
            }
        }```Is this better implementation? :> Did I succeed

    // Eat
    _item.transform.position = Vector3.zero;
    _item.transform.SetParent(null);
    _item.gameObject.SetActive(false);
    // Check if correct order
    manager.CheckOrder(_item.order);
}

#

show the full code. because i have a feeling that something else is affecting it since setting the object inactive apparently fixes it

hallow sun
#

something like this:
test 1 (with this code): _item is not removed from its parent, everything before and after works fine
test 2 (remove transform.position line): _item is removed successfully, but triggers CheckOrder twice for some reason

#

Food(Clone) is _item
Making it inactive doesnt solve this problem, it solves the double trigger problem and then i can just delete transform.position since that was its only reason to be here.

Hey quick question. Trying to figure out how to skip items in a queue:
I have a queue of 6 items, being the sentences in the boxes photo (following a brackey's tutorial). Currently, I have these items in a queue, however, I want to be able to skip to certain lines when a variable is called. If I remove items from the queue, will it destroy this string list? Or how would you go about skipping lines? Here is how I am storing the string[]:

    public void StartDialogue(Dialogue dialogue)
    {
        Debug.Log("Starting Dialogue with " + dialogue.OpponentName);

        nameText.text = dialogue.OpponentName;

        SentenceQueue.Clear();

        foreach (string sentences in dialogue.sentences)
        {
            SentenceQueue.Enqueue(sentences);
        }

        DisplayNextSentence();
    }
``` Any help is much appreciated. I apologize, Queues are not my thing 😅
image.png
slender nymph
#

a queue is supposed to be first in first out, is there a specific reason you're using a queue and not like a list if you want to be able to just skip elements?

untold shore
#

Actually thats fair. More this is what it was already coded on, so Ill probably just have to make a new method real quick. Didn't realize it was first in first out 😭 . Mainly its because of this:

 if (SentenceQueue.Count == 0 )
        {
            LevelContinueButton.SetActive(true);
            EndDialogue();
            return;
        }

Do you think I could make a new queue with specific items from the list? Is that unoptimized?

Ohhhh

burnt vapor
#

Consider using a dictionary and listing the dialogue items by a key if you want an easier time getting dialogues

Right now you have an index with no clear explanation what it is, which can be confusion

Alternative an enum is also nice because you can give a name behind the index

Hey, I am working on a game with a system that requires inputs from the player in order to do an attack (Left arrow, right arrow, up arrow, down arrow like Friday Night Funkin or Dance Dance Revolution) and I am working implementing attack animations to each arrow input. Any idea on how I would set the animation to only play of the last input pressed?

#

I am using animator in Unity for the animations

untold shore
burnt vapor
#

So you can define a dictionary with 2 generic types that indicate the type of the key, and the type of (in this case) the dialogue

untold shore
#

Huh. I need to look into that, that actually seems really useful!

burnt vapor
# 
Dictionary<string, DialogueType> dialogues = new Dictionary<string, DialogueType>();

// You can also fill it with lines from initialization
Dictionary<string, DialogueType> dialogues = new Dictionary<string, DialogueType>()
{
  ["Dialogue1"] = "Hello, World!",
}

// Or add it later.
dialogues.Add("Dialogue1", "Hello, World!");
dialogues["Dialogue1"] = "Hello, World!";

Syntax might be a bit off here

#

Then you can just get it with dialogues["Dialogue1"]

#

There are additional checks to ensure a key exist:

if (dialogue.TryGetKey("Dialogue1", out var dialogue))
{
  // The dialogue exists
}
#

So you see it's easy. It's also very fast

#

Just make sure the keys are unique obviously

edgy tangle
#

If you’re pressed for time it might not be the best option right now , but in a past jam I did I liked the system we used, which was to have a dialogue queue defined in a ScriptableObject, with a UnityEvent field in each dialogue that would invoke when that line was finished. So you could then trigger different dialogue like a choice dialogue, or enable/disable objects, etc.

untold shore
#

Oooo ok. I still need to study it a little more (I promise you, im beginner beginner. This is my first coding game), but I really want to try it!

burnt vapor
#

Try it and see, it's super easy to use

#

Easier than fiddling with indexes probably

untold shore
edgy tangle
#

So like <string, string> means that you lookup a string by using a key as a string

#

Just a real dictionary. You need some block of text (the definition of the word), which you look up by the word itself

edgy tangle
#

It saves you from having to validate it more specifically

burnt vapor
# untold shore Most likely 😅 Quick question that I am confused about is the out var? On the a...

There are methods that start with Try. These are often, if not always, using what called the "Try Parse" pattern. The idea is that you attempt the action, and instead of returning the type as a result it returns a boolean indicating success. Any additionally returned information (such as the dialogue in this case) is returns in what's called "out parameters". These are explicitly keyworded with "out" to indicate they are set inside the method and will have a value when the method ends.

#

If the try method returns true, it can be assumed all parameters with "out" are set

#

This is the code behind the Dictionary. Note it explicitly has out defined, and therefore will set this variable before it ends.

#

Otherwise, it returns default(TValue), which is often just null

#

Also, is dictionary like a type?
Yes, almost everything in C# is. Maybe you mean the <string, DialogueType> part?

untold shore
#

Dude this is actually so cool! Trying it out right now.

timber tide
#

Dictionary best data struct

#
  • iterator
burnt vapor
#

The Try pattern can be found in many things. For example, int.TryParse attempts to parse its parameter (which is mostly a string) into an integer, and returns a boolean type indicating if it works

#

Theres also int.Parse which instead tries to parse, or throws an exception if it failed

untold shore
#

Nope, just didn't know where it would go honestly. So what could my dialogue type be? I have a dialogue script:

using UnityEngine;

[System.Serializable]
public class Dialogue
{
    public string OpponentName;
    [TextArea(3, 10)]
    public string[] sentences;
}

But thats only for the queue method. Would it be something else?

burnt vapor
#

So you see there's generally always an alternative that's not as graceful

timber tide
#

Only problem is you can't serialize dictionaries with unity :D

burnt vapor
#

Yeah, Unity doesn't support this natively. There are packages online that add support though

#

Not for the actual type, I believe. They add a new type similar to the Dictionary, but makes it serializable

            ContinueButton.onClick.AddListener(EndDialoguePostWin);

I dont think you can set independent values. Gotta make a new vector each time

Mornin all, been a while since I've been around here.

I'm having a bit of a struggle with a little simple 3rd person turret game idea. Idea is that the player controls a turret and has to shoot at paratroopers dropping to the floor 'downrange'. I'm using a raycast direction to control the rotation of the turret 'parts' but I'm struggling to get what I want from the vertical rotation.

I'd like for the turret's x rotation to be 0 if the mouse pointer goes below the halfway point of the screen but I can't seem to get my head around the maths involved.

#

This is the code I'm currently running

using UnityEngine;

public class TurretController : MonoBehaviour
{
    [SerializeField] Transform turretBase;
    [SerializeField] Transform turretPivot;
    [SerializeField] Camera mainCamera;
    [SerializeField] float rotationSpeed;
    // Update is called once per frame
    void Update()
    {

        Debug.Log(Input.mousePosition);
        //Debug.Log(Screen.width);

        Vector2 mousePositionOnScreen;
        mousePositionOnScreen = new Vector2(Input.mousePosition.x, Input.mousePosition.y);

        Ray rayToWorld = mainCamera.ScreenPointToRay(mousePositionOnScreen);
        var aimAt = rayToWorld.direction;

        Quaternion newTurretBaseRotation = Quaternion.LookRotation(aimAt - turretBase.localPosition);
        newTurretBaseRotation.x = 0f;
        newTurretBaseRotation.z = 0f;

        Quaternion newTurretPivotRotation = Quaternion.LookRotation(aimAt - turretPivot.localPosition);
        newTurretPivotRotation.y = newTurretPivotRotation.y/2;
        newTurretPivotRotation.y = 0f;
        newTurretPivotRotation.z = 0f;

        turretBase.localRotation = Quaternion.Slerp(turretBase.localRotation, newTurretBaseRotation, Time.deltaTime * rotationSpeed);
        turretPivot.localRotation = Quaternion.Slerp(turretPivot.localRotation, newTurretPivotRotation, Time.deltaTime * rotationSpeed);
    }
}

Hello guys! Is that the right approach to delay the shooting? With awaiting Task.Delay? Or is there a better approach?

    private async void FireSingle()
    {
        Debug.Log("FireSingle");
        isShooting = true;

        Shoot();
        await Task.Delay((shootingDelayMilliseconds);
    }

    private async void FireBurst()
    {
        Debug.Log("FireBurst");
        isShooting = true;

        if (burstBulletLeft <= 0)
        {
            isShooting = false;
            return;
        }

        Shoot();

        if (burstBulletLeft < bulletsPerBurst)
        {
            await Task.Delay(shootingDelayMilliseconds );
        }

        burstBulletLeft--;

        FireBurst();
    }

Muck very cool game, anyway, to answer your question: You can use a camera as a viewport, take a picture using a render texture, and then load that based on the name of the object, it's probably best to not do this at runtime, unless required, as you can just match a texture2d to an item name or something for said pictures, but, reading the pixels of a render texture, then writing that to a file, saving it as a png, is how that could work

I don't think there's a "best approach" or even a better, but, some alternatives to look into if you don't like how you are doing it:

  • Use invoke with a time, it will delay the call until the delay is over,
  • A coroutine using yield return new WaitForSeconds(x);

I'd say your way is perfectly fine, there are alternatives, as with everything, you can look into them if you prefer them over your way

#

Invoke(Method, Seconds); I believe for invoke

# stuck field I don't think there's a "best approach" or even a better, but, some alternatives...

Thank you! It's more like I know C# because I work as a web developer in .NET environment, but completely new in Unity.. Sometimes I tend to use stuffs which I already know in C#, but there may be better approaches or more used pattern for these situations programming with Unity!
I tried the Invoke method but I was't able to make it work, because I made the methods recursive and the Invoke is not really waiting the end to fire again, so I might refactor a bit to use that.. I'll have a look to Coroutine which I have never used!

What's a good way to keep track of how many monsters are in my scene so I can spawn more if some have died?

#

I'm thinking to use a reference list on my spawn script and just count the number of entries every few seconds?
If the referenced object is destroyed it's removed from the list as well right?

#

Or I could throw an event every time a monster dies to adjust a count somewhere

timber tide
#

singleton

#

event works, or just let the enemy do its own callback

topaz mortar
#

So I'd just have a singleton like MonsterCounter that keeps track of all the monsters?
Guess I can adjust it to include which scene the monsters are on

timber tide
#

GameManager works fine too if you want to keep it minimal

#

I say EnemyManager if you want to do something like object pool

timber tide
ruby python
timber tide
#

make the background plane very close to the turret

#

so the depth is smooth

#

probably better ways to handle it but I think that can work

ruby python
#

Yeah, but then you lose accuracy when shooting far off distance. lol. (I know, sorry, really not trying to be a pain. lol.). I'm going to try using a sphere collider somewhere 'middle' distance (I want the paratroopers to drop at different depths) that I think will work.

The convenient thing about this is also that you're not hard tied to an interval. If for some reason you want some sort of cooldown, you could just decrement the value of _nextTick (or whatever you end up calling it) instead of extra steps to get it working
And also, if you had to tie a visual indication of the time left, you can just get the difference _nextTick - Time.time and use the result in some progress bar for example
And lastly, if it matters to you, this is very multiplayer friendly since you just need to inform users of the next timestamp in most cases.

#

Your approach also works. Alternatively a Coroutine also fits in here. There are no wrong paths with it really, but I personally had the best experience with Time.time

# 
public class Example : MonoBehaviour
{
    private float? _nextBurstFireTick = null;
    private float _burstFireInterval = 0.1f;
    private bool IsBurstFiring => _nextBurstFireTick != null;

    void Update()
    {
        // Fire the next shot
        if (IsBurstFiring && Time.time > _nextBurstFireTick)
        {
            Fire();
            _nextBurstFireTick = Time.time + _burstFireInterval;

            // Additionally you'd increment some counter here to ensure we stop firing at some point.
            if (HasShotThreeTimes())
            {
                _nextBurstFireTick = null;
            }
            return;
        }

        // Start burst firing
        if (PressedFire())
        {
            Fire();
            _nextBurstFireTick = Time.time + _burstFireInterval;
        }
    }
}

Semi pseudo code, gets you an idea of how Time.time can very easily be included with a system so you can separate the burst firing logic

#

And yes, this is all copy pasted from a previous message

proud escarp
#

Thank you! Yes I will surely add a multiplayer later (very later on 🤣 ), I might give this Time.time a shot!

Any simple way to detect if an object I would Instantiate would collide with another object before instantiating it?
For my monster spawner, so I don't spawn monsters (which collide with eachother) inside another monsters collider

#

Or should I use a simple workaround like force them to move away from the spawn point?

ruby python
#

I'm not sure how efficient it is tbh, but I've always used OnCollisionStay ( or OnTriggerStay) if true, move it, if not move on to the next thing.

Ah, 30 minutes wasted on trying to figure out why Physics.OverlapSphere is not working, to then figure out I need Physics2D.OverlapCircle

hi, im making an incremental game and im currently making the upgrades for it. how should i go on about making upgrades that do different things (i.e, one upgrade adds +1 to your click and another sends a robot out to do clicking for you)? is there a way to implement all of these possible behaviours into one central UpgradeItem script?

visual linden
# sterile radish hi, im making an incremental game and im currently making the upgrades for it. h...

I would try to think in abstractions. You want to be able to change what happens when you click, so that's some kind of "ClickBehavior", but you also want there to be a robot that can do the clicking for you, so this is some kind of "Clicker" system.. Normally, the Clicker is of type CursorClicker; and a CursorClicker is controlled by the user for manual clicking. Every time the CursorClicker calls Click(), it invokes the DefaultClickBehavior (adding a 1 to the score). At some point, the user upgrades their ClickBehavior to a BetterClickBehavior- Now, when their CursorClicker calls Click(), it invokes BetterClickBehavior which adds 2 to the score.
Then the user gets an upgrade that swaps out their CursorClicker for a RobotClicker; Now it's not controlled by the cursor any more, but by a robot that goes out and calls Click() on its own, invoking the current (or default) ClickBehavior every time.

You'd probably implement this with some kind of base class that has a type of IClicker and IClickBehavior. But architecturally there's a lot of room for how you set it up and what exactly you need for your game specifically.

for knockback? why not a parabola?

#

parabolas define how things fall

ashen frigate
#

it doesnt look like it does parabola

#

ohhh wait maybe i need to y = x^2/2

naive pawn
#

wdym?

#

you'd want a parabola that opens downward, so y = -ax^2 for some a

#

but you don't need to actually have a parabola

a parabola is just the shape an object traces under gravity, ignoring air resistance
so just simulate gravity and you'll get a parabola

i need x^2/a and a needs to be a bigger number so it wil go up slower rn is shot up

Yes, you can do whatever you want.

The above example doesn't do any functionality, it's purely for organizing your data so that you can incorporate it into the logic and gameplay.
