Vectors are a fundamental mathematical concept which allow you to describe a direction and magnitude
Is the direction stored in C# vector3 object, or is it calculated only in reference to some other Vector3 ?

[teal viper]

Is it raw data? Or does it contain headers? Do you have a link to documentation?

[languid spire]

so if you are interacting with a React Web App why are you not using UnityWebRequest?

[potent nymph]

I suppose it's raw data in a sense

[teal viper]

It is stored in the Vector3

[potent nymph]

that is the answer suggested by this post https://stackoverflow.com/questions/75124607/how-to-convert-base64-mpeg-to-audioclip-in-unity
which worked great in the editor, but not in the build due to the use of Application.persistentDataPath not working as expected

[night mural]

Think of it as relative to (0,0,0). As a point, it's an offset relative to that position. As a vector, it's an 'arrow' which starts at the origin and ends at that 'point'.

[languid spire]

Sorry but if you use UnityWebRequest corretly there is no need to use PersistentData

[crimson ibex]

How can I retrieve it from Vector3 object , via normalized ?

[potent nymph]

I don't think UnityWebRequest can read base64, only URLs I believe

The purpose of PersistentData (in the SO answer) is to store the converted base64 as a url, which unitywebrequest can read

[keen dew]

The vector itself is a direction

[night mural]

It already has the direction implicit in it. If you normalize it, it will be pointing that direction with a magnitude of 1, which is useful if want to scale it by some other amount instead of it being the length it already is.

[keen dew]

if you need it normalized then normalize it

[languid spire]

There is no reason for the data to be in base64, your web backend can send the data correctly with the right mime type

[potent nymph]

There is no backend

[languid spire]

you said a React Web App, that is the backend

[crimson ibex]

Hmmm time to go back to school algebra . Thank you @keen dew @night mural @teal viper

[potent nymph]

I said the audio is recorded by the user, so the audio is stored on the user's browser. A React App is not a backend

Firebase would be considered a backend, but I'm not storing anything on there yet

[teal viper]

So you have unity WebGL build integrated in a react app, is that correct?

[potent nymph]

yes

[night mural]

sorry i haven't really been following, what's the request for if there's no backend?

[potent nymph]

To send a recorded audio clip to the unity WebGL build

[night mural]

you can probably send a POST with the data you want in the right mimetype but if you have no backend i'm not sure that makes sense

requests don't send stuff, they request stuff

[teal viper]

You already know how to convert your data to a byte array. From there look up "unity create audioclip from bytes". There were a few promising results on the unity forums.@potent nymph

[potent nymph]

Yes, I think I looked through all of them

[night mural]

if there's nothing external you shouldn't need to make any requests

[teal viper]

There was a result about using AudioClip.Create. look it up.

[potent nymph]

@night mural that's correct, and that is exactly how I'm passing in things like numbers, strings, and even textures to the WebGL build from the frontend. But for audio it's a bit more tricky

[night mural]

i mean, they can send stuff, but it seems like a weird way to accomplish what it sounds like you're doing (though admittedly i am missing a lot of context)

[night mural]

oh i see, so the react app wraps the unity app and you are making requests to it? then it is sort of a backend but i get the confusion

[potent nymph]

there are no requests being made, but they do interact with each other

[night mural]

what does that mean

well if you don't want to send it as base64, you can probably POST it with the right content type, but i'm not sure if that solves your problem: https://docs.unity3d.com/ScriptReference/Networking.UnityWebRequest.Post.html

[potent nymph]

the react app acts as a wrapper so I can use certain web apis (like accessing the web cam, microphone, and using other js libraries)

[wide tapir]

anyone know why?
every other animation works fine even idle injured works fine
only when the injured walk is played
ive tried replacing it with every animation but every animation does it in the "injured" state
except idle

[night mural]

yeah that's interesting! but i've never done that so i donno how gnarly it is to get those to talk to each other

[teal viper]

It seems like there's an animation event in that animation, and you're not handling it.

[thin hollow]

is there something like MonoBehaviour.OnApplicationQuit() except when the scene changes?

[teal viper]

Either remove the animation event, or create a method to receive it.

[teal viper]

There are callbacks in SceneManager that you can subscribe to.

[night mural]

just in case you didn't also find this https://forum.unity.com/threads/how-to-convert-base64-mpeg-to-audioclip.1398631/#post-8820691

[teal viper]

Yeah, that's a solution similar to what I've found as well.

[potent nymph]

I haven't tried downloading a package with nuget before

[teal viper]

Try the solution in the post first.

[potent nymph]

yes, the solution requires this library https://github.com/naudio/NAudio

[stuck jay]

If I have a character and I want to implement stats for said character, would it be better to just spread the stats out around many scripts (so Health would have HP, Movement would have MoveSpeed, etc) or place them all in a single class called Stats?

[teal viper]

Where do you see that it requires it? They just mentioned that it could be helpful.

The main thing is AudioClip.Create and .SetData.
Assuming your data is in the correct format, you just need to convert it to a float array.

[potent nymph]

but as I'm trying out the codes, certain methods don't seem to exist, such as ConvertByteToFloat

I can only assume I'm missing something

[teal viper]

That method is defined in the topic starter post.

[potent nymph]

never mind I see the function from the OP

[night mural]

Either can work. If you'll have a few stats into which many effects are distilled systemically and are unlikely to add more on a whim, it might be simpler to just group them together as a core part of a character. If your stats are going to be more numerous/complex/interesting/broad-reaching, you might want something more component-based and flexible to enable that.

A lot of things in games can be distilled down to 'a tag and a number' but it's often useful to draw boundaries between them anyway. Call your tag+numbers that every character needs Stats and couple them to the character functionality. Call the ones that are more dynamic Auras and apply/remove them dynamically. Whatever helps you keep things organized!

[potent nymph]

The solution on the post didn't seem to work at first but at least I heard a sound. I'll keep working on it

[languid spire]

just a thought, can you not use indexedDB to pass the data between the react app and the unity app?

[night mural]

i think that was the original plan? (webgl uses indexedDB to store persistent data)

[potent nymph]

I was looking into that, I'm not sure

[night mural]

pretty sure you can save the file in there and then pull it out but i don't know how that works offhand (just that persistentDataPath points there somehow in webgl builds)

[languid spire]

I think a lot will depend on how the React app has wrapped the Unity app

[potent nymph]

I'm using this module: https://react-unity-webgl.dev/docs/api/send-message

[teal viper]

I think the main issue here is what kind of data do you get from the microphone in JS and how to convert it to a format that AudioClip expects.

[native seal]

could I have some pointers for architecting a class/ability system? should I have a BaseAbility which inherits from scriptable object then have for example "ActiveAbility" and "PassiveAbility" inherit "BaseAbility?" or should I not use scriptable objects? same thing for class, I want to have a class system along with subclasses. for example an Archer could become a Marksman or a Trapper later on. Should I have a base "Class" which inherits scriptable object. Then have "Archer" inherit "Class" and then have "Marksman" inherit "Archer." Does this make sense?

[teal viper]

Would definitely recommend SO for abilities, as you'd probably have a lot of them, and SOs are easy to config and change in the inspector. As for classes, you might need a combo of SOs for data and plain classes for behaviour. Though, it depends a lot on your project.

[native seal]

I am making an ARPG very similar to diablo 3 or path of exile

[teal viper]

Inheritance is an option, but there's also composition and you can combine both too.

[native seal]

I was just worried going down the tree of inheritance since I would be making a new scriptable object for each ability

since I want completely seperate logic

[night mural]

then i would probably avoid inheritance and try to do as much composition as you can

[native seal]

alternatively though, I could have an AbilityLogic class which every ability SO has?

not sure

[night mural]

yep, definitely avoid trying to build a complicated hierarchy here as it will never work

[teal viper]

Yeah, still it depends on the project. 2 arpgs can have a totally different architectures

[native seal]

yes just wondering the most effective way of doing it

[night mural]

the answer is always 'it depends'

[cosmic dagger]

focus on composition and try avoiding an inheritance chain, especially, for BaseClass > Archer > Trapper, etc . . .

[native seal]

or atleast what to avoid

[native seal]

how would I do that using composition

[night mural]

what do your items look like? what do your abilities look like? where do they come from? what sort of things can modify them and how? in an arpg the answer is often 'everything affects everything' which leans more towards an ECS kind of architecture

[native seal]

just have the player have a class and subclass?

which are two seperate things

[static bay]

If your game is small I see nothing wrong with an inheritance structure. Say the Spire did the same and ended up alright.

[teal viper]

Break the classes logic into smaller common objects and logic steps and make them into their own classes.

[static bay]

If you want the ability system to be pretty complex, then ya consider composing them.

[native seal]

yes thats what I planned on doing

each class woudl just store a list of abilities

and have a name

[night mural]

well composition would mean that instead of PassiveAbility and ActiveAbility classes, your ability class would have an ActivationTrigger (or something like that) which would be set to 'always' for passive and 'player_activated_manual' for an active one (not a great example but hopefully you get the idea)

[static bay]

Ya I think it's fine to have some base ability class that holds things like name, cooldown, targeting strategy, cooldown, etc and then a list of "Effect" classes.

[teal viper]

Then you can just have one SO with many instances representing the classes

[native seal]

yep okay

[native seal]

i think im too far in to convert everything to ecs, no idea how that even works as well

but yes everything does effect everything

[night mural]

you don't have to actually 'do ecs' to adopt ideas from the architecture

[native seal]

what does that entail then?

[night mural]

behavior as composable data components which are processed by systems at logic time

but where and how you'd implement that would depend on, like, what your game is actually made of

[static bay]

Ability systems can be such a rabbit hole I swear.

Especially turn based.

[cosmic dagger]

truth . . .

[native seal]

yeah just dont want to go to deep and end up regretting how I did it

not turn based though

[night mural]

oh that will definitely happen

but that's how you learn

[native seal]

true

[night mural]

it's because an 'ability' isn't really anything and often means 'anything that can happen in the game'

[static bay]

Do you need "triggers"? Like "this character has a buff that heals themselves whenever anything takes damage"?

[native seal]

most likely, anythng you would see in the likes of Diablo, POE, etc

or an MMO

those types of abilities

[night mural]

oh yeah, ezpz

[native seal]

its more specific in my case i guess, just skills with cooldowns etc

would using a strategy pattern make sense so the character doesn't have to deal with all the ability logic

[night mural]

what i'm describing here is essentially the strategy pattern

[native seal]

ah okay

[night mural]

compose your abilities out of strategies for the different things an ability must do

[native seal]

so generalize them as much as possible? like im most likely going to have multiple skills that will shoot projectiles in some way

that can just be setup with parameters

[night mural]

e.g. for league of legends, they determined that 'missiles' in their game need to do these things

so each missile can implement a strategy for how it does those things

from this article, donno how practically useful it is because their diagrams are too small 😦 https://technology.riotgames.com/news/behind-leagues-new-missile-system

[native seal]

so avoid writing a seperate script for each abilities logic?

and generalize them to projectile, melee, DOT, etc

[night mural]

if each ability is truly unique and it would be difficult or tedious to distil them down into reusable components, having a script for each might be ok

[native seal]

im not sure yet

[native seal]

thanks for this

[night mural]

but generally if you want your game to be heavily modifiable at runtime like an arpg tends to be, you need things to be data driven

if every ability is an opaque script which just gets Cast()ed and nothing knows what it does, that's ok but it can make it trickier if you have a modifier that needs to reach in and tweak that ability (or that the ability needs to factor into its execution)

[static bay]

The way I would do it is that you have.

• Spells
• Targeting Strategies
• Effects
• Actions
• Triggers

Spells hold data like name, case time, cooldown etc, as well as a list of effects.
Targeting Strategies collect some subset of objects to be used in Effects.
Effects create Actions, and load them with relevant data (DamageEffect for example would create a DamageAction instance).
Actions are the ones that actually change the game state and send events out for Triggers to respond.
Triggers are fancy "event listeners" that will set off new Effects when relevant.

[night mural]

yeah, that's a good setup

[native seal]

hm okay thank you

i like that

[night mural]

effects can be damage, applying an aura, a knockback, etc.

it can get complicated though, as you'll quickly find that you want to do things like 'this ability hits everything in an area, but it should also affect friendly targets, and if the target is friendly it should heal them instead of damage, and if should only hit the 5 closest targets to the center, etc. etc.'

games be complicated though and there's no solution that makes everything simple

[static bay]

Yep you're gonna wanna be pretty robust with your Effects. For example with this, you can have it so your DamageEffect takes in a "Targeting Strategy". This is a separate class whose sole job is to define what entities we're aiming to hit with the effect.

You can have conditional effects that will execute different sub effects depending on conditions etc.

It can get wild, but it's important to identify all these different pieces.

[native seal]

yeah for sure, I do feel like hard coding the abilities would be easier but on the other hand they may all feel slightly different

and would be much harder to add new abilities

[static bay]

Depending on the game scope, ya maybe.

[native seal]

idk yet its my first game

[night mural]

then you should probably just hard code all the abilties 😛

[native seal]

but I do have a lot of ideas

[night mural]

a lot of what's hard about this is actually the presentation of it

making vfx/sounds/hits/reactions/etc which can properly convey all of these things which your complicated and amazing ability system can accomplish can be a lot of work and very tricky

it's easier to convey things to players if they work consistently, but a very flexible system need not do that

[native seal]

yeah thats a later me thing

to polish everything

just want to get the systems down

ill make room for all of it but not implement it

[static bay]

Hey just for clarity, to run the "Actions" you'll need some ActionManager class that'll take in actions and then execute them whenever you want. This is basically the command pattern.

[native seal]

ah yea okay

[stark girder]

if(Input.GetKey(KeyCode.LeftShift)) 
{
    CurrentForwardVector = transform.up;
    speed += 1f * Time.deltaTime;

}else if (speed > 0)
{
    speed -= Time.deltaTime * 0.2f;
}

if (Input.GetKeyDown(KeyCode.Space))
{
    RaycastHit2D hit = Physics2D.Raycast(transform.position, transform.up);
    if (hit.collider != null) 
    {
        Destroy(hit.collider.gameObject);
    }
}
transform.position += CurrentForwardVector * speed * Time.deltaTime;

I want to make a space ship movement
when accelerated in a direction it should continue in that direction until the thrust is applied in a different direction

I have the part where it continues in a direction but I want a gradual change to another direction when thrust is applied
how do I do that?

[cosmic dagger]

the ability system is basically a separate project in itself . . .

[native seal]

well its integral to an arpg

[static bay]

Yep. You're basically making a little engine.

If you want some easy intermediate, do what Slay the Spire did.

[native seal]

thats why im approaching it with caution

[static bay]

Base Ability class with some abstract "OnCast" method.

Override that method, which creates those Actions I mentioned.

You skip the complexity from Effects and Targeting Strategies and whatever.

Just an ability class, an override, and executable actions to change the game state.

Don't ask how they did triggers.

[native seal]

only issues im thinking that might arise are setting ability damage/speed/whatever and having that react to things happening to the player such as debuffs etc

[night mural]

😮 i really want to know now though

[native seal]

what do you mean by triggers?

like things that happen when getting hit etc?

[night mural]

'this card does 5 damage. when the target is weak, it does 5 damage again'

[native seal]

ah okay so conditionals

[night mural]

'every time you play a skill, gain 5 block'

[static bay]

"Cards" were their base class, and they had an overridable method for every event they cared about in the game. Many cards just have empty methods because of it. Whenever an event went off they just iterated through every card in the game and call some specific method.

[static bay]

When X happens, do Y.

[night mural]

haha that's amazing, i love it

[static bay]

You want a separate object to handle the "listening" of the X and making sure values are correct, and the Y is just a list of Effects again.

[night mural]

you see, beginners? just do what works and make your millions

[static bay]

Tbf they had Actions and a proper ActionManager and all that.

But their triggers were.... mmm

[night mural]

i figured becuase the sequencing works pretty well, queueing is smooth

but also it doesn't really work, if you watch speedruns there's all sorts of sequencing issues that can be exploited

[static bay]

See using my suggested setup, this could be solved with some ConditionalEffect. This effect takes in 2 sub effects and a "condition". When you ask the Effect for a an Action, it evaluates the condition and just runs whichever sub-Effect is relevant.

But again, this is pretty robust.

[night mural]

yep that's pretty much what i did in my slay the spire clone

[static bay]

And then you have to ask the question of "Well how do I feed in proper contexts, some effects care about different things in the game?"

and then you get into Blackboards and value grab bags and sdgjibghlrfdghmnteohmgkfdlgntmbrfgt

[polar comet]

apparently I can't multiply the -transform.right in this line but is there a way I could use it anyway ? Here is the line : rb.AddTorque(-transform.right * 0.05);

[static bay]

and suddenly you're basically writing your own scripting language

[native seal]

so this is indeed a rabbit hole lol

[night mural]

but all my cards were fully data driven so i could serialize them and modify/save them out at runtime because apparently i'd rather waste time than release a game

[static bay]

and then you just start convulsing

[native seal]

is there documentation for how slay the spire did this?

[night mural]

nah i gave up on that shit ages ago and my gamestate is a blob

embrace the blob

[static bay]

YES YOU SEE THEN YOU JUST START PASSING THE ENTIRE GAME STATE THROUGH EVERYTHING BECAUSE FUCK IT

[night mural]

sure, scorll up 😄

[night mural]

this is the guiding light of ecs

make everything public but control access patterns

game state is meant to be queried

let it live happily in the light

[cosmic dagger]

is there an error? i'd post it so we can see what the problem is. also, what is 0.05?

[static bay]

I'll fucking query my fist through your face.

and you are welcome to, as my face is simply a component of myself and all are free to read or write to it as needed

[static bay]

noooooooo

[languid spire]

0.05 is a double you need to use a float

[polar comet]

here is the error : Assets\frontWheelMovement.cs(31,26): error CS0019: Operator '*' cannot be applied to operands of type 'Vector3' and 'double' and I'm trying to multiply -transform.right by 0.05 to get a very slight movement

[polar comet]

oh ok that's the problem

ty

[cosmic dagger]

as i figured. i mentioned 0.05 because you were missing syntax to make it a float . . .

[native seal]

https://imgur.com/aq68rOa is this relevant? this is how for honor tackled this

[polar comet]

ok

[night mural]

hahaha they gave a whole talk on it, hang on

[native seal]

"So the "Modifier_SwordAttack" with a "Damage: 20" property would inflict 20 damage on the opponent if the Opponent is a ValidTarget. In addition, the Enemy would also take the "Modifier_BurnDoT" Modifier into it's Handler and run a Timer for a specified duration that deals a specified amount of damage to the Enemy. "

[night mural]

https://www.youtube.com/watch?v=JgSvuSaXs3E

[native seal]

im wathcing that now lol

[night mural]

there are a lot of great gdc talks

that one i watched and then was like 'that's it?' but there were a few smart tidbits

keep in mind that these kinds of talks are solving Ubisoft scale problems which it would most likely be a waste of time for you to solve

[native seal]

yeah true, but the idea is still the same

[night mural]

they literally cannot have someone just open up the ability script and edit it because there are 50 people all working on the project at the same time, so they must split things up

you don't necessarily have to unless you are gaining from it

[native seal]

makes sense

[static bay]

Seems pretty close to what I was talking about. You can see similar terminology to what I was saying.

• Modifiers = Spells
• Effects
• Actor Selector = Targeting Strategy
• Conditions

I think the most important aspect of ability systems is just realizing that all abilities can be broken down into.

• When do I activate?
• Who do I effect?
• What do I do?

If all of these aspects are easily swappable in your system, you're gonna have a good time.

[honest haven]

anyone about?

[native seal]

when dealing with the who do I effect part, is a good way to handle it to pass in a layer? so for example, an enemy can use a "player" ability and allow it to hit the player without having to change the ability

[static bay]

Like a Unity Layer?

[native seal]

sure, say im using an overlap circle or a collider

that i would modify

[static bay]

No I don't think that's good. Hide the Unity stuff in some derived class. For example imagine this.

public interface ITargetStrategy
{
    public List<GameObject> GetTargets();
}

public class OverlapTargetStrategy : ITargetStrategy
{
    Vector3 origin;
    float radius;
    LayerMask layerMask;

    public ColliderTargetStrategy(Vector3 _origin, float _radius, LayerMask _layerMask)
    {
        origin = _origin;
        radius = _radius;
        layerMask = _layerMask;
    }
    
    public List<GameObject> GetTargets()
    {
        return ///Do Overlap Sphere and feed in those above variables
    }
}

public class Spell
{
    ITargetingStrategy targetingStrategy;
    List<Effect> effects;

    public void Cast()
    {
        var targets = targetingStrategy.GetTargets();
        foreach(Effect effect in effects)
        {
            var action = effect.CreateAction(targets);
            ///Load your action into the action manager for processing. 
        }
    }
}

[night mural]

it might be useful to have a concept of 'teams' and then if you wanted to, you could have a bitmask for whether something targets allies or enemies or both or whathaveyou

[polar comet]

can I use a float to rotate a gameObject ? I'm to lazy to create a quaternion

[native seal]

wow thank you, very helpful

[night mural]

but that would just be one piece of the stuff above, where your targeting strategy could factor in the team or not

[native seal]

where would I implement that concept?

ive been only thinking in terms of layers

[static bay]

Ok now here's the PSYCHO SHIT. You see that cast method? Fuck it. It's for nerds and squares.

Make Spell just hold data.

Create a CastSpellAction and have that define what it means to cast the spell.

[night mural]

that's what i'd do

i think, i haven't actually made or thought about making an arpg so maybe in practice i would feel differently

[native seal]

so then create multiple " CastSpellAction"'s for each different spell

[static bay]

What're the different spell types you want?

[native seal]

create projectiles (different speed, formation, pierce, chain, etc), apply dot affects, ground effects, melee attacks (different shapes, windup times, makes character move), passives, heals, etc etc

i think most skills could be generalized under one of those

another thing to note, i want to make skill tree that can modify each of these skills

that would still be conssitent with this architecture right

[static bay]

A couple of these are different "types" of things, but I believe they can all be handled by Effects and Actions. For example your projectile could be spawned by a "CreateProjectileAction", which creates whatever prefab you want and then provides it with a list of Effects to execute whenever it hits/does whatever it needs. Then you could have a projectile that heals or damages or teleports or whatever.

Whatever your actions can do, it'll be able to do that.

[night mural]

this also turns out to be a good idea because by having most things be a projectile, you can tie visuals to that projectile even if it's not actually an active missile

[static bay]

Applying a DOT effect would definitely be an action, but youd need some DOT managing system to handle the lifetimes of these things. The DOT can again just create more actions when it goes off, so you can again create a DOT that does anything. Damage, heal, teleport, etc.

[night mural]

e.g. your summon skeleton spell might still want to shoot out a tendril of mist to where they are spawning from so that the player knows what's going on (a ground targeted projectile which triggers a spawn when it hits)

[static bay]

Simply put you just have Actions that spawn entities that do other actions 😛

[night mural]

and you can always have a projectile with 0 travel time

[static bay]

Modify in what way? If you have specific tiers of Spells with upgrades you know (like Slay the Spire), you could literally just create a new Spell that's supposed to represent the upgrade.

If it's really dynamic, you might have trouble.

[night mural]

this is way more common than you'd expect

[native seal]

couldn't the dot Action apply an Effect on the target which then is evaluated every frame?

so every target would be evaluating its list of effects to see if they apply

[night mural]

you can also combine it with simpler effects for that 'family' so that you can have 'bone spear rank 2' which shoots 2 spears and now they come back to you but also 'bone spear damage increased by 50%' which should affect all ranks

[native seal]

not 100% sure yet but it wouldnt be super dynamic

[static bay]

Actions are one time executables. Your "ApplyDotAction" would create some separate DOT object that'll be handled by some other system. That Dot object might have its own set of effects that go off on its timer.

[native seal]

can you clarify what you mean by Effects?

[night mural]

i tend to call those Auras copying WoW, but some kind of concept for persistent effects which tick is very useful

[native seal]

in my mind im thinking each action will have a set of effects that it applies to whatever it hits, then the hit target will evaluate those effects

[static bay]

So the way I imagine Effects are that they are "blueprints" for actions. They're the ones that evaluate the game state and decide what should be done. They just don't actually change the game state.

Actions change the game state.

[native seal]

so the actions would have the damage, cooldown, attack speed etc

the effects are just how the action applies those

[night mural]

Effect = 'thing that can happen in the game, in the game's terms, like 'damage can be done'
Action = actual state change which reflects that effect, which could actually be composed of multiple actions, like 'subtract 10 from State.playerHealth'

effects are more for 'design time' and can include conditions and extra context stuff to decide whether they should happen or not

if they should, then they get resolved into a set of actions

[burnt vapor]

Dunno. Does the code actually run? Try placing a debug message at the end of the methods to make sure.

[static bay]

I know they sound similar, but trust me it's super valuable to separate the pieces that figure out WHAT to do from the pieces that actually do the thing.

[night mural]

this is that composition we keep harping on

[static bay]

You will like have shit like DamageEffect and DamageAction.

[native seal]

so the target will evaluate the several Effects to see if they should turn into Actions? like if the enemy is poison resistant, it would evaluate a PoisonEffect to false and not turn it into an Action?

[night mural]

there are a few ways to do it really

in practice you probably still want to trigger the effect but then RESIST! it so that you can provide that feedback to the player instead of just nothing happening to that unit

[static bay]

Yes that's one way to do it.

[night mural]

but you could do that at either end really

[native seal]

as in the "projectile" would evaluate if it should apply its Actions to the target instead

okay i appreciate it a lot, going to tackle this all tomorrow its 3 am lol

thanks for all the help

[static bay]

Back when I tried my hand at this, this was my DamageEffect.

    public class DamageEffect : Effect
    {
        public ValueProvider<int> DamageValue { get; }
        public ValueProvider<EntityData> DamageTarget { get; }

        public DamageEffect(ValueProvider<int> damageValue, ValueProvider<EntityData> damageTarget)
        {
            DamageValue = damageValue;
            DamageTarget = damageTarget;
        }

        public override GameAction GenerateAction(in GameContext gameContext)
        {
            int damageValue = DamageValue.GetValue(gameContext);
            EntityData damageTarget = DamageTarget.GetValue(gameContext);

            var damageAction = new DamageAction(gameContext.Source, damageValue, damageTarget);

            return damageAction;
        }

Don't ask what a ValueProvider is 😛

[night mural]

i have those too 🤝 gotta resolve dynamic values for stuff out of the gamestate so that you can do damage based on other things!

[static bay]

yeeeeeeeeeeeeeeeeep

Rabbit Hole

I do think that a sort of ECS-like structure is the best for these systems.

I think I reached a point where Actions weren't even doing anything.

[night mural]

sounds like you owe me a new FACE

[night mural]

a lot of my actoins do nothing or very little, and systems hook into them to actually generate the actions instead of having them be tied to the effect like yours

[static bay]

They just carried data given to them from the Effect, sent out an event, and then Systems would hook into these events and modify the game state based on that data.

[night mural]

yepyep

[static bay]

ITS DOOMED

[night mural]

it feels really nice because your features sort of live in independent slices

[static bay]

ya and the definition of what anything "does" can be swapped out

[night mural]

runtime composition is best composition

but don't tell the javascript devs

[static bay]

var entity = gameState.Entities.CreateEntity();

var damageEffect = new DamageEffect(7, new CasterProvider());

var healEffect = new HealEffect(5, new GameContextTargetProvider());

var eventValue = new GameContextValueProvider();
var boolProvider = new IntComparisonProvider(eventValue, 5, Comparison.GreaterThan);
var boolProvider2 = new IntComparisonProvider(eventValue, 10, Comparison.LessThan);

var andProvider = new AndProvider(boolProvider, boolProvider2);

var condition = new Condition(andProvider);

var trigger = new Trigger(EventHelper.AfterEvent<DamageAction>(), entity, condition, new EffectResponse(healEffect));
gameState.Triggers.AddTrigger(trigger);

var damageAction = damageEffect.GenerateAction(new GameContext(trigger, new Context(), gameState));
gameState.ActionManager.QueueAction(damageAction);

gameState.RunToCompletion();

Ya I was really down the hole.

[night mural]

but i understand...somewhere i have a sea of ContextProviders and ContextValueResolvers from long ago

[static bay]

It was kinda cool when it all worked.

Maybe I'll dip my toes back into it in the future.

[night mural]

yeah it sure forced me to learn how to use generics and stuff better than i knew back then

and then once i got it working i was like 'great now how can i avoid having to do this ever again'

✨ game dev ✨

[static bay]

If it wasn't OBVIOUS what this does, it creates a Trigger that heals anyone who takes damage for 5 if the damage value is greater than 5 but less than 10 🙃

[night mural]

to be fair this stuff looks worse in code than if you built an inspector to abstract hide away a lot of the ugliness 😄

[static bay]

Just use these.

[waxen cypress]

Just a quickk quesiton. Im making a vr game still x_x. How hard would it be to code zero gravity like a space game

[night mural]

well you can set gravity to 0 or don't use rigidbodies and there ya go

[waxen cypress]

oh

does that include if i wanna make certain objects float?

also wat abt movement like if i grab could i throw myself or will i need to code in something like climbing

[night mural]

i'm not sure what the xr toolkits include by my understanding is that they are pretty terrible

[static bay]

You'd need to code all that regardless of VR tbf.

[night mural]

well they might include some kind of hand pulling locomotion?>

[static bay]

VR dev isn't thaaaat dfferent other than the Camera being super glued to your head.

[waxen cypress]

ye ik but im still rly new and still trying to understand

idk why i picked this stupid idea for my major

[night mural]

you should start by making a simple non vr game to understand unity

questions like 'how do i make objects float' don't really make sense and you're wasting your time thinking about them

[static bay]

agreed

[hot wave]

what is a nice namespace for GameInput?

can it be gameinput also?

not sure how namespace works

[waxen cypress]

tru, the only reason i ask simple things is because i wanna make a space game with some puzzles. Since this is for my major work for school and will go towards my final mark when i leave so Im also on a time limit

rip

[teal viper]

Look up in the docs.

[nocturne parcel]

But this is far from a simple thing. "How do I make objects float" is too broad of a question, with many answers. You should follow a simple tutorial, get to know VR development.

Then get more specific.

But i'd start turning gravity off with 0 drag 🤪

This is not for VR, but teaches a lot about zero gravity environments

[loud python]

Hello everyone Im having some trouble here and i've been stuck for alteast 24 hours on this My item prefab slot is a button with a text gameobject child and a image gameobject child. I keep getting this error ""Chest Content is not assigned.
UnityEngine.Debug:LogError (object)
InventoryItemController:TransferToChest () (at Assets/Scripts/Inventory system/InventoryItemController.cs:97)
UnityEngine.EventSystems.EventSystem:Update () (at Library/PackageCache/com.unity.ugui@1.0.0/Runtime/EventSystem/EventSystem.cs:514)

" This script https://paste.ofcode.org/EZtNcFt6vLThDC8t8xRZiG < is trying to call the TransferToChest method in the OnClick fied of the inspector in the button UI. now it makes sense at first, because in order for the item prefab to be instantiated initially it needs to be interacted with from the world "scriptable object" then it gets instantiated with this code https://paste.ofcode.org/TquWcJPGREU4wKYx6fKBsG < and then the item prefab slot spawns under the content in the Canvas of the inventory. Now im trying to transfer it to chest using the InventoryItemController with an onclick (double click item prefab). I assigned all the properties in the inspector and it gave me this error up above. But It wont let met actively assign data in the prefab of the item because when the game starts it is not instantiated yet. so the properties prefab are not there on start up. basically the gameobject field in the button click is empty on start up because the item hasnt been instantiated yet. so I created this script >https://paste.ofcode.org/iJP3bxYEkqjCsAnXhW9HdY to try to instantiate all objects on start and still no luck. if anyone can hlep it would be great

[languid spire]

I see nowhere in that code that calls SetChestContent on InventoryItemController

[loud python]

no it only calls for transfer method because im setting the chestcontent in another script and calling it in this one because unless it is initailly instatiated on play (which its not) it wont let me assign content in gameobject field

I have to assign it manually in play mode

in the inspector after it as already instatiated

[languid spire]

so why are you posting code that is irrelevant to your problem? Post the code where you call SetChestContent

[loud python]

im trying to learn here is this not beginner channel?

Chestcontent is not beign assigned because there is nothing to assign it up on start up

how do I fix this?

[languid spire]

how can I tell you if you don't post the correct code?

[loud python]

[languid spire]

AI Generated code?

[loud python]

I mean not all of it but some of it

[languid spire]

you know we don't provide help for AI code

[loud python]

why what its helping me learn wtf

[languid spire]

server rules

[thorn holly]

How’d you know?

Out of curiosity

[languid spire]

Seen too much of the crap it generates. It's pretty obvious

[thorn holly]

Huh, interesting

[dusk dust]

Hey guys, I'm moving a game object that is a child of HorizontalLayoutGroup (using OnDrag and changing the loacalPosision), and when OnEndDrag is called I'm trying to reset the position of the object to the position that it started with, I tried storing that location and manually change the localPosition, but it's not resetting to the location that intended When I was trying to figure out I noticed if I paused the game And just moved that child with the mouse it will try to move but will rest to the location that I want (the inforced location by the laoutGroup), Any Idea if there's a function that I could call It will reorder the children?

[thorn holly]

Kinda sad ngl that game dev and programming may be taken over by ai

[languid spire]

what is even sadder is that young aspiring devs are resorting to using this crap instead of putting in the effort to learn properly, it says a lot more about them than the AI tools they are using

[loud python]

Facts but ive learned more using the AI so whatever helps you learn right

[thorn holly]

Yeah, I’m pretty young, currently working on my first game and I’ve learned programming techniques using scratch, codecademy, and an ungodly amount of googling

[languid spire]

you're lucky you've got Google, when I was learning all we had were very expensive books

[thorn holly]

Huh, learning programming from a book, sounds…interesting

Idk, my dream job is to be a game dev so I’m trying to build a solid foundation

[low path]

It’s hard to use AI if you don’t already know how to code. Most of the time what it gives you is not what you want. Sometimes you get lucky. Sometimes, though, it gives you something that looks right at first glance but actually takes longer to fix after. Problem with AI code is where the programmer comes with it and doesn’t understand why it doesn’t work and then can’t answer any of the questions this server has for them because they didn’t write it and don’t understand it.

[languid spire]

Imagine the time you spent on Google and then times it by 100, that's what I'm talking about

[thorn holly]

Oof

[thorn holly]

Well, it’s a sure fire way to learn, if your spending so much more time on it - I just hope using google doesn’t form cracks in my programming knowledge

[languid spire]

very well said

[thorn holly]

I agree, to an extent, the same applies to YouTube tutorials such as “making your first unity game” and such. You have to learn how to take away information and experience from the video, rather than copying down whatever it tells you

[languid spire]

oh, it will, the benefit of using books is that even when you are looking for something specific other things, releated or non related will catch your eye and be remembered for future use

[low path]

The best way to learn imo is to try to do a thing yourself and look up everything you need to know to do that thing on your way.

That way you are the agent of creation and need to learn from your mistakes.

[thorn holly]

Exactly, that’s how I learned dictionary’s, delegates, is statements, and a lot about unitys workflow

It’s a great way to learn and apply new concepts quickly and make them stick in your brain

[faint sluice]

Is there a function to get a list without specific element in a way it doesn't affect the original list?

[low path]

You can use LINQ’s where() function.

[languid spire]

LinQ, but please don't

[gaunt ice]

you have to deep copy everything

[faint sluice]

I do hear a lot that linq is super slow and should be avoided but I don't understand why and how it is slow?

[faint sluice]

I mean yeah can manually create a function with addrange and all, just wondered if there already existed a method

[languid spire]

It generate tons of garbage and it has to gate check everything, 90% of what it does is unnecessary overhead

[low path]

It is slow because it creates a lot of objects dynamically.

It’s not as bad as people make it out to be, especially where you use it for one off code or whatever.

You generally don’t want to use it for highly repeated code. It should also be said that for a small project while learning, the code brevity you get from linq can be an advantage and won’t meaningfully affect performance.

[gaunt ice]

getting sub-list of list is just shallow copy, if you dont want to affect the original list, you have to deep copy everything (unless you just want the "list" itself not to be changed, not the objects inside)

[languid spire]

to start with why List -> List? Why not List->Array as you know the size of the destination?

[faint sluice]

Fair point, I guess I'm just used to doing list everywhere 😅

[languid spire]

List is much less performant than Array

[faint sluice]

I think tarodev debunked it earlier? Both perform almost same?

I mean with respect to speed atleast

[languid spire]

then he is wrong under most circumstances

[faint sluice]

I might be misremembering too, I'll go recheck

[gaunt ice]

you can write code as

public int Filter(T[] original,T[] results ,Func<T,bool> predicator){}
```then return the count and store the values inside results

https://learn.microsoft.com/en-us/dotnet/api/system.array.findall?view=net-8.0
the one of ms returns an array

[magic crown]

Hey, So small question i'm making a game and right now i have a public GameObject variable that i want to assign but through a script, not through the inspector. How do i do that? been a little while i've been looking and saw nothing sadly.

[low path]

You need to get a reference to that game object somehow.

[languid spire]

GameObject.Find, if you really must

[low path]

There are many ways to do that so it depends on circumstances.

[magic crown]

Right now this is what i have

i get the GameObject variable and try to make it equal to this game object but sadly it don't really work

[languid spire]

why would it?

show code for Blueportal

[low path]

this is kind of weird... you are saying test is the blueportal on the same gameobject, but then you are also saying that test's orangeportal is the same gameobject

[languid spire]

and doing it in Update is just wrong

[faint sluice]

Nvm it wasn't about array vs list, it was linq vs loops to filter lists

My bad

[low path]

both scripts are on the same gameobject so why would you need to inform them of that gameobject?

[magic crown]

doing it in the update cause just doing some test don't wana call the script each time i shoot my portal right now

[languid spire]

but that will make absolutely no difference. but anyway your code looks ok as long as both components are on the same game object

[magic crown]

oh have to make it on both?

[languid spire]

im guessing you are getting an NRE

[magic crown]

nope it unassigned not null since it a public game object

[languid spire]

best show the actual error

[faint sluice]

If you try to use unassigned variable, it will still give null reference error

[magic crown]

"UnassignedReferenceException: The variable orangePortal of Blueportal has not been assigned.
You probably need to assign the orangePortal variable of the BluePortal variable of the Blueportal Script in the inspector"

[dusk dust]

I used LayoutRebuilder.ForceRebuildLayoutImmediate(_layoutGroupRectTransform);
for the RectTransform in the layout group that is in the parent
if anyone will has a similar problem 💙

[magic crown]

oki thanks for the info

[magic crown]

and that happen each time i walk in the blue portal

[languid spire]

So your GetComponent<Blueportal>() is failing

probably because you are looking on the wrong game object

[magic crown]

they are not on the same gameobject orangeportal script is on the orangeportal and blueportal scrip on the blue portal

[languid spire]

so why are you looking for it on the same gameobject?

[low path]

"GetComponent" gets the copmonent on the same gameobject

[magic crown]

ooooh yeah did not think about that X) gonna try something else

[low path]

if you call "GetComponent" from "OrangePortal", it will get the component of "BluePortal" on the same gameobject as "OrangePortal"

[magic crown]

completely forgot about that yeah

[languid spire]

Also, style police moment. Keep your naming consistent. It hurts to type OrangePortal and Blueportal

[magic crown]

oh okay sorry

i don't usualy ask for help on the discord and just look at the documentation or tutorial

[low path]

one common way to get references like this is to have some manager component that holds references to components you need. all gameobjects that care about that manager have a reference to the manager and can ask for whatever they need. another way is to query the scene geometry like with a raycast or a collider. another way is to use find.

there are a lot of tools you can use and the appropriate one depends on the circumstances

[magic crown]

oh wait i found one of my big problem and mostly why it did not work is i completely forgot to add my orangeportal script to the orange portal

[magic crown]

oh okay thanks for the info

will be usefull in the future

[queen adder]

Trying to make a toggleable world light on top of a flashlight, but I keep getting an unsassignedreference errow how to fix?

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

public class NewBehaviourScript : MonoBehaviour
{
    public GameObject target;
    public GameObject fullLight;
    public KeyCode key = KeyCode.F;
    public KeyCode lights = KeyCode.Colon;

    void Update()
    {
        //target.SetActive(Input.GetKey(key));
        if (Input.GetKeyDown(key))
        {
            target.SetActive(!target.activeSelf);
        }   

        if (Input.GetKeyDown(lights)) { 
            target.SetActive(!fullLight.activeSelf);
        }
    }
}

shouldn't have pinged my bad

[swift crag]

well, what line is the error on?

you need to start with that

[languid spire]

np, also screenshot the inspector

[queen adder]

21, just found it I'm calling target.SetActive again instead of fullLight nvm

[swift crag]

target.SetActive will cause an error if target is null

[languid spire]

yep, that makes no differene even though it is wrong

[swift crag]

fullLight.activeSelf will cause an error if fullLight is null

Any use of the member access operator -- . -- can cause an exception with a reference type

(along with the indexer operator, [])

[queen adder]

I see, then what method should I use to attach those pieces of code to their respective GameObjects?

[swift crag]

Just make sure that both are assigned in the inspector.

[languid spire]

the inspector

[swift crag]

since these variables are public, they're serialized by Unity by default

[queen adder]

they seem to be in the GameController object

[swift crag]

this means they will appear in the inspector, and that Unity will remember the values

Perhaps an object is being destroyed, or you have multiple copies of NewBehaviourScript

You can check the latter easily

Search in the Hierarchy view with this:

t:newbehaviourscript

[queen adder]

oh yeah I have 3

[swift crag]

That'll do it

Clicking on an error in the console will (often) take you to the offending object in the hierarchy, by the way

(single-clicking)

[queen adder]

didn't know that thanks

[swift crag]

You can also do this with your own logs

Debug.Log("Oops", this);

[queen adder]

one last thing though the Lights toggle doesn't work

[swift crag]

The method takes a second argument -- the "context"

you can pass any unity object in

here's an example of how I use that...

if (category.label.IsEmpty || string.IsNullOrWhiteSpace(category.label.GetLocalizedString()))
{
    Debug.LogWarning($"{category} has an invalid label", category);
}

category is actually an asset

clicking on that log entry takes me to the bad asset in the project window!

[queen adder]

oh that's neat

[queen adder]

not getting any errors for it but my other method reading a colon in isn't working at all

[swift crag]

you should use Debug.Log to see if the if the colon key is being noticed at all

[languid spire]

The problem will be that ALL instances of the script will be trying to do the same thing

[queen adder]

nope don't think it is being noticed

[queen adder]

huh, I see now

[languid spire]

why have this script on more than 1 game object?

[queen adder]

not sure, just thought it was possible to save space and keep everything under an "activation" script

but by all means if that's not best practice I'll make a new file

[languid spire]

I mean if you are checking for specific keyboard input it makes sense to only do that in one specific place

[queen adder]

would anyone here be able to help me with a chunk of code i js cant get right?

[languid spire]

maybe, if you actually post the !code

Hello. I'm getting warning while trying to simulate animation on y axis. If anyone can help me I would be super grateful I'm down to share more details.

[queen adder]

basically, my wasd movement is all good its just the gravity and jump i need now. i can move up and down slopes but when i try jump yvelocity.y returns NaN

[errant pilot]

Guys can I send a small 5 sec vid for my problem?

[lone ferry]

I m trying to move an object with Getaxis, its working fine just that there is some unnecessary drift after I let go off the key. How can I remove that

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

public class PlaneController : MonoBehaviour
{
    public float speed;

    // Update is called once per frame
    void Update()
    {    
        float moveHorizontal = Input.GetAxis("Horizontal");
        float moveVertical = Input.GetAxis("Vertical");

        transform.Translate(Vector3.right * moveHorizontal * speed * Time.deltaTime);
        transform.Translate(Vector3.forward * moveVertical * speed * Time.deltaTime);

        float clampedX = Mathf.Clamp(transform.position.x, -20f, 20f);
        float clampedZ = Mathf.Clamp(transform.position.z, -20f, 20f);
        transform.position = new Vector3(clampedX, transform.position.y, clampedZ);
    }
}

[wintry quarry]

GetAxis has some built in "smoothing". Use GetAxisRaw if you don't want the smoothing

Also rather than calling Translate twice have you considered combining everything?

Vector3 moveDir = new(moveHorizontal, 0, moveVertical);
transform.Translate(moveDir * speed * Time.deltaTime):```

[errant pilot]

Guys why do my gizmos change position as the window size changes

These codes are everything related to it

topLeft = new Vector2(transform.position.x, transform.position.y);
bottomRight = new Vector2(bottomrightX, transform.position.y - 23.5f);

colliders = Physics2D.OverlapAreaAll(topLeft, bottomRight);

Gizmos.DrawLine(topLeft, bottomRight);

[lone ferry]

got it, it worked with GetAxisRaw, thanks

[wintry quarry]

Your gizmos are probably not at the same z position as the game world objects (they're at z == 0 based on your code)

and you are probably using a perspective camera

[errant pilot]

like i should try to make the objects y=0 for instance

[wintry quarry]

z not y

[shell sorrel]

just makes sure both vectors in the DrawLine have the same z coord

[errant pilot]

I did both i also changed my camera

[errant pilot]

ya mb i meant z

didint work

[wintry quarry]

you changed your camera in what way

[errant pilot]

i made it orthographic

[shell sorrel]

also where does bottomrightX come from

[errant pilot]

i assign it

[wintry quarry]

then you should be all good now

[errant pilot]

its still not working 😭

[wintry quarry]

Oh wait

what is your game world made of?

[shell sorrel]

its not a z thing since they are vec2

[wintry quarry]

Did you happen to build your game out of UI elements?

i.e. is everything happening on a canvas/

[shell sorrel]

yeah could be a overlay canvas

[errant pilot]

yes

a lot not all

[wintry quarry]

yikes. Well that's your problem

your UI is rescaling as you change window sizes

[errant pilot]

it shouldnt?

[wintry quarry]

the gizmos are not moving

no, UI is for UI

gameplay should happen in world space

[strong laurel]

Uh.. anyone? 👀

[errant pilot]

but the problem is the plant i spawn is a child of a UI object

[wintry quarry]

yes that's a problem indeed

none of the gameplay stuff should be UI

[wintry quarry]

You are trying to use some animator parameter that you didn't define in the animator

double check the spelling of your parameter

[errant pilot]

ok and lets say i take them out of UI what difference does it make to my game?

[wintry quarry]

it makes your objects have consistent world space positions

[shell sorrel]

fixes this problem

[wintry quarry]

and then your gizmos (which also have consistent world space positions) will not not appear to "move" when the screen is resized

[shell sorrel]

but otherwise just different workflow

can still accomplish what you want, just might have some extra logic for fitting the camera to things

[wintry quarry]

Also all physics, lighting, code etc generally operates with world space coordinates which will now make sense

[errant pilot]

ok and if everything is out of the canvas and i want to rescale my window theyll all like resize?

[shell sorrel]

no reason they could not all be done with sprite renderers and maybe a tilemap

[errant pilot]

like all the objects i take out of it?

[rancid tinsel]

i just noticed that my objects are still detecting mouse hovering etc when behind ui elements, is there a quick fix to that at all?

[shell sorrel]

depends on how you detect that

but are a few ways

[wintry quarry]

How are you detecting the mouse currently? The best solution is to switch from whatever you're doing now to using IPointerEnterHandler etc

[rancid tinsel]

so OnMouseEnter etc

[wintry quarry]

yes, so switch to the Event System stuff

[shell sorrel]

yeah use the EventSystem and its handlers

and make sure you have the correct kinda raycaster on your camera for it

[wintry quarry]

https://docs.unity3d.com/Packages/com.unity.ugui@1.0/manual/SupportedEvents.html

[shell sorrel]

once done this will be automatic

[rancid tinsel]

is it just a case of including "using unity.eventsystems" and then changing the OnMouse functions to pointer ones?

[slender nymph]

no, you need to actually implement the interface(s) and if you are using world space objects then your camera needs a Physics Raycaster component

[rancid tinsel]

would that be physics 2d raycaster for a 2d game?

[shell sorrel]

do this objects have 2d colliders on them?

[rancid tinsel]

yes

[shell sorrel]

if so yes

once setup, event system will cast with GraphicsRaycaster to check for UI hits, if no UI handles it, then it will cast via the physics 2d raycaster

[rancid tinsel]

you mean this bit?

[slender nymph]

that's part of it, yes

[shell sorrel]

yes those are interfaces, after you add them, you implemented the methods they require

so for IPointerEnterHandler it requires you to create a void OnPointerEnter(PointerEventData eventData) method

[rancid tinsel]

i see

onmousedown would change to public void OnPointerDown(PointerEventData eventData)?

[shell sorrel]

correct

but also needs the corsponding thing up top

[rancid tinsel]

yup

[shell sorrel]

IPointerDownHandler

[rancid tinsel]

got it

thank you so much

and works like a charm 🙂

[shell sorrel]

if your ide is setup correctly, it should create the methods for you after extending from the interface

like my will go red after adding it, then offer a quick fix

[rancid tinsel]

yeah that scared me for a second but actually putting the methods in fixed it

[shell sorrel]

yeah interfaces are a useful concept

they are essentially a contract

if something is a IPointerEnterHandler its more a contract saying it implements a method, and can be asked to use it later without needing to know what the exact type is

[spiral narwhal]

private const Vector2 PLAYED_CARD_SHADOW_OFFSET = new(5f, 5f);

Are vectors runtime dependent? I.e. do I have to use two float constants instead?

Constant initializer must be compile-time constant

[low path]

it's not that the vector itself is "runtime dependent." you need to pass in a compile-time constant. "new Vector2" is a dynamically created object

[spiral narwhal]

Ahhh yes that would make sense

[low path]

also this

https://learn.microsoft.com/en-us/dotnet/csharp/misc/cs0283?f1url=%3FappId%3Droslyn%26k%3Dk(CS0283)

[shell sorrel]

@spiral narwhal no const on the vector types since they are just structs

you could do a readonly static for similar effect

private static readonly Vector2 PLAYED_CARD_SHADOW_OFFSET = new(5f, 5f);

[hollow forum]

ive made a movement script but it works even if i take my finger off the movement key

any hlep?

[faint sluice]

Code?

[wintry quarry]

without seeing the code, how can we help?

[hollow forum]

using System.Collections.Generic;
using UnityEngine;

public class Player : MonoBehaviour
{

    Vector2 inputVector = new Vector2(0, 0);
    private void Update(){
        if (Input.GetKey(KeyCode.W)) {
            inputVector.y = +1;
        } 
        if (Input.GetKey(KeyCode.A)) {
            inputVector.x = -1;
        }
        if (Input.GetKey(KeyCode.D)) {
            inputVector.x = +1;
        }
        if (Input.GetKey(KeyCode.S)) {
            inputVector.y = -1;
        }

        inputVector = inputVector.normalized;
        
        Vector3 moveDir = new Vector3(inputVector.x, 0f, inputVector.y);

        transform.position += (Vector3)moveDir;
        Debug.Log(inputVector);
    } 
}

[wintry quarry]

move Vector2 inputVector = new Vector2(0, 0); to inside Update

alteranteively just do inputVector = Vector2.zero; as the first line in update

but... can you see why? You're not ever resetting it

[hollow forum]

oh that makes sense

because once i edit it it doesnt stop cause it doesnt update when i take my finger off

thanks

[odd widget]

is it better to use Quaternion.LookAt or is it better to just to use Trigonometry and Rotation to make an object rotate around something?

like this

[timber tide]

Im lazy so I use lookat

you can also run into gimbal issues with Quaternion.Euler though

[odd widget]

🤔

i never heard of gimbal

[pallid nymph]

is this for a 2d thing?

[odd widget]

is he the ancient wizard that makes unity?

[odd widget]

yea

i want to make a gun that rotates around the player

[timber tide]

ah, that's fine then since you only need to rotate on one axis

[pallid nymph]

your code seems fine in that case... there's a constant like Mathf.DegToRad btw, I assume that's what you're doing

[odd widget]

oh

what's the difference between system Math and unity math?

[languid spire]

system Math uses doubles, unity math uses floats

[odd widget]

aaah

[pallid nymph]

not big, Unity's has a few more things, I guess

[odd widget]

thankyou guys

[pallid nymph]

Unity's actually uses System.Math under the hood, so in a sense it too uses doubles for many things 😄

[odd widget]

unity math is just system Math but with fake mustache and a trenchcoat

[pallid nymph]

exactly

[swift crag]

and some extra operations that are useful for game development

e.g. SmoothDamp

[pallid nymph]

I hate that they tried to be smart and implemented Mathf.Sign to only reutrn +1 or -1, and not 0 when input is 0...

okay, not hate, but highly dislike 😄 took me some time to fix a bug, because I didn't expect the function to behave like that

[polar acorn]

I mean, 0 is positive

[pallid nymph]

Math.Sign return 0 for 0 🤷‍♂️

[languid spire]

as opposed to -0 which is negative

[odd widget]

my math teacher would shake her head in disagreement if she sees this

a light shake

[pallid nymph]

while there are two 0 representations, there shouldn't be much difference... I'm not sure -0 would actually give you -1, but am now curious

[torn edge]

Can someone tell me why it isn't playing music from my audio manager

[polar acorn]

In computing, there are positive and negative zeros, as Steve was alluding to. In floating point arithmetic, only positive 0 is actually achievable, but there are two zeroes as far as your computer's ALU is concerned

[polar acorn]

Nothing here actually plays any audio

Your Play function searches for a sound and then does nothing with it

[torn edge]

oh word

but doesn't s.source.Play() do that

[polar acorn]

There is nothing of the sort in any of the code you've posted

[torn edge]

oh wait

this

[polar acorn]

That wasn't in the code you shared before. Is this AudioManager?

[faint sluice]

Wait we can add multiple audio sources on same gameobject and have it work perfectly?

[polar acorn]

As long as you have some way of differentiating between them because GetComponent will get one at random (actually whichever one has the lowest GUID which is practically random as far as the human is concerned)

In this case, since they're stored in a list as they're added, you can properly reference each individual one

[torn edge]

Yes yes

idk why it didnt show up in the file

Maybe I didn't save it

[faint sluice]

Didn't know that, that's cool

[polar acorn]

Try saving and running it again

[torn edge]

Ohh yeah it works now

Thanks!

[pallid nymph]

well, at least in the Editor, Unity is returning 1 for Mathf.Sign(-0), so yeah - it's a sad implementation 😛

[wintry quarry]

Sign explicitly says it returns 1 for 0

[pallid nymph]

that is true, but it's weird, because it's not same as Math.Sign, and most things in Mathf are wrappers around Math

so why change this one to what I'd call random behaviour, instead of naming it something else

anyway, not the end of the world, just kinda weird if one is used to Math's implementation

[polar acorn]

Pretty sure there's no actual way to make -0 as a float

[pallid nymph]

-1f / float.PositiveInfinity is a 0 that if you ask float.IsNegative returns true, that's as close as I could get 😄

it wouldn't print as -0, but float gets the weird point of what I'm trying to do 🤷‍♂️ 😄 and Mathf.Sign doesn't... which is normal, it treats both 0s the same way and returns 1... which to be fair is what it says it does, just doesn't match Math's behaviour 😄

[rancid tinsel]

is it possible to make a general script variable, and then have that variable be assigned any script in code?

as in, a non-specific script

[verbal dome]

What is the usecase?

[shell sorrel]

use case heavily depends on how to approach

like got static, got singleton's, got SO's everything could reference

[verbal dome]

Component is the base class. But sounds like maybe your problem can be solved in another way

[languid spire]

yes, static class, static variable

[rancid tinsel]

i have two different tower types with two separate scripts, i want to check which script is attached to a selected tower (whether its towertypeA or towertypeB) and then assign the script to a selectedTowerValues variable

selectedTowerValues would be the "non-specific script variable" in this case

[shell sorrel]

since you have a concept of selectedTower

i would feel that what you really want is a script that holds reference to all towers, and defines which is "selected"

[rancid tinsel]

this is what ive thought of but im not sure if it will work

[verbal dome]

Do the tower scripts inherit from the same base class (not counting monobehaviour)?

[rancid tinsel]

unfortunately no

[shell sorrel]

ok, and if that case passes what do you wnat to do with it

[verbal dome]

That could be useful. Or using an interface

[rancid tinsel]

so if i went that route id have to change quite a lot of code

[shell sorrel]

so give them a common base class

or make a interface for them

that they all implement

[verbal dome]

Probably better than digging your self into a deeper hole 😄

[rancid tinsel]

maybe 😭

[rancid tinsel]

inheritance?

[shell sorrel]

like TowerBase is a new type

then you have a class BallistaScript : TowerBase {

and others

[verbal dome]

Inheritance (sharing a base class) is one option, interfaces is another

[shell sorrel]

interfaces are generally more ideal if there is no shared logic

but also are a pain to use in unity if inspector referenced

so also got the option of a abtract class as a base

public abstract class BaseTower : MonoBehaviour { }

public class BallistaTower : BaseTower { }

public class CannonTower : BaseTower { }

for example

then BallistaTowers and CannonTowers could all be stored in the type BaseTower

then could type switch later

[languid spire]

Adding an interface at a late stage will be a PITA as you will have to seriously mod the existing code. Adding an abstract base class is the path of least resistance

[shell sorrel]

would also put any common logic in the base since its the stuff you could access without a type cast

[rancid tinsel]

wouldn't this work as a workaround - I know it's not good practice but I think I would get really demotivated if I had to change so much

[shell sorrel]

and what type would selectedTower be?

a GameObject?

[rancid tinsel]

yes

[shell sorrel]

so that could work, but giving them a common base class i fee ls cleaner

[rancid tinsel]

it definitely is, but I haven't experimented/practiced with that before so I feel like it would lead to a lot of hours of work for me

[shell sorrel]

switch (selectedTower) {
    case BallistaTower ballistaTower:
        break;
    case CannonTower cannonTower:
        break;
    default:
        throw new ArgumentOutOfRangeException(nameof(selectedTower));
}

other nice feature of the common base class, is using type switches

though if dead set on your GetComponent approach

please use TryGetComponent instead of calling it twice

[rancid tinsel]

what happens if TryGetComponent fails?

[stuck jay]

Where could I write single variables, like setting a projectile's owner through a GameObject variable?

[shell sorrel]

if (selectedTower.TryGetComponent(out BallistaScript selectedTowerValues)) {

[languid spire]

class baseClass {
static int selectedId;
void SetSelected() { selectedId = GetInstanceId(); }
bool IsSelected() ( return selectedId == GetInstanceId(); }
}

[shell sorrel]

it returns a bool if the thing exists or not, then sets the component on a out param

[rancid tinsel]

so that one line both checks if it exists, and if it does then assigns it to the selectedTowerValues variable?

[summer stump]

Yes

[shell sorrel]

if (selectedTower.TryGetComponent(out BallistaTower ballistaTower))
{
    // do stuff with ballistaTower if it exists
}

[summer stump]

It CREATES a local selectedTowerValues
To be clear

Leave out the type if you want to assign it to a class member variable

[shell sorrel]

in that case would want a new one

since it would be a different unrelated type for each case

[summer stump]

Yeah, I didn't see any of the previous stuff. Just wanted to make that clear for any future use.

[shell sorrel]

i still think the common base class is the approach that should be used

[languid spire]

absolutely

[shell sorrel]

since that lets you have logic that is for all things of this category

then lets you cast to the concret type if you need to handle per type edge cases

[rancid tinsel]

like this?

[summer stump]

Looking back at the conversation, I agree too. It would make things far easier to handle

[shell sorrel]

yes

[rancid tinsel]

im really regretting not having both towers use the same script now lol

but this seems to work as a workaround

thank you

[shell sorrel]

it would not be hard to literlaly just make a base class for all towers

then have both of them extend from it

[rancid tinsel]

im not sure how that would affect the rest of the code I have though as it's probably a mess

[shell sorrel]

initially it would have no effect

but would let you gradually move stuff into the base class you want to share between both as you want

and allow you to store both of the tower types in a field of the base type

and cast to figure out what type it is

[noble forum]

Hi, does anybody have a script for auto card positioning like big cards games have? It would take forever to do it by myself to look good.
I mean in hand
You draw a card and it is getting placed somewhere, different depending on amount of cards you already have in hand.
like here, the position of cards is different depending on how many cards one have

[shell sorrel]

that is not very hard to code

just a wee bit of math, and would best be done per use case

[faint sluice]

It's not that hard to code bro...barely 10-15 lines of code

[swift crag]

there will not be a pre-made script that does exactly what you want

[timber tide]

no one gonna hand out code here tbh

[noble forum]

really? i thought of many, many more

[shell sorrel]

its just modifying a position based in how many cards you got

its just a tiny bit of math

[timber tide]

ugui could probably do most of the work, but I know hearthstone does everything custom

[shell sorrel]

would first just make it space cards properly based on count

like figure out a offset, which is the card width + padding

add that offset * card number to the x position

[timber tide]

there's one other consideration and it's smushing cards closer if you don't want a proper gap

[shell sorrel]

the gap could be a ratio based on the total count though

gets larger to a max with fewer cards

gets smaller or starts to overlap with more cards

all in all, what you want is really just math, and is simple if you break the problem down

[timber tide]

actually doesn't look like they smush on the board there, but hearthstone does

in hand however they probably do

[crimson ibex]

Hey @gosthir i also struggled for the same. I tried buildinga grid system, but could not figure out in 3d. 2d is in built

[noble forum]

so foreach active card just move position by card_wight to the right, and every next card -card wight * times_it_has_been_decreased right?

[thorn iron]

Hello it's me again.
How can I customize JsonUtility's serialization of certain field of my class ?
For example I have a class Item :

public class Item : ScriptableObject
{
  public string Name;
  public string Description;
  public int Value;
  ...
}

And a class ItemSlot :

public class ItemSlot
{
    public Item Item;
    public int Quantity;
...
}

Both are used in
public class Inventory : ScriptableObject
{
  public List<ItemSlot> Materials;
  ...
}

How can I save the Inventory in a json ?

I have tried with this method

public class Inventory : ScriptableObject
{
  ...

  public void Save()
        {
            // Serialize this player Inventory as a string in json format
            string saveData = JsonUtility.ToJson(this,true);
            BinaryFormatter bf = new BinaryFormatter();
            // Get the string representing the path to the save file
            string path = string.Concat(Application.persistentDataPath,savePath);
            FileStream file = File.Create(path);
            bf.Serialize(file,saveData);
            file.Close();
        }
  public void Load()
  {
      if(File.Exists(string.Concat(Application.persistentDataPath,savePath)))
      {
          BinaryFormatter bf = new BinaryFormatter();
          FileStream file = File.Open(string.Concat(Application.persistentDataPath,savePath),FileMode.Open);
          JsonUtility.FromJsonOverwrite(bf.Deserialize(file).ToString(),this);
          file.Close();
      }
  }
}

I could save & load when I'm still in the unity editor.
As I left and reenter the unity editor and loads, the item are not recognized.

The Image is what the json looks like.
I have an Idea of making an ItemDatabase containing a dictionary<int ID,Item> that can gives me the Item when providing the ID of said Item.
But I don't know how to let Json Serialize only the Item's ID and not the InstanceID

[timber tide]

dont save by the instance ID, either save by asset ID or generate an ID yourself

[shell sorrel]

the instance id is because they are trying to save out a whole SO

really if this is for save data no reason to have it be a SO and not just a regular struct or class

ScriptableObjects are really for cases where you want to treat something like a asset

[thorn iron]

I made a ScriptableObject to create a lot of Items faster

[timber tide]

if you don't need to write unique data, but only structure it by SOs, ID lookup to SO is a fine idea

[wintry quarry]

Make Inventory a regular class

[shell sorrel]

and Item

[wintry quarry]

As for custom serialization https://docs.unity3d.com/2021.2/Documentation/Manual/script-Serialization-Custom.html use this or make separate DTOs

[shell sorrel]

also ontop of those issues, no reason to use the BinaryFormatter

[thorn iron]

oh ok

[shell sorrel]

If items already exists as SO's for other reasons can keep them

but SaveData i would make be its own thing

maybe it has a ID to the SO's you make

then can find the correct SO to reference by putting them all in a Dictonary with a id as a key

[thorn iron]

how do I say to JSonUtility to Serialize the Item's ID from a dictionary instead of it's InstanceID?

[shell sorrel]

you make it your self

[wintry quarry]

For anything deriving from unityEngine.Object, JsonUtility is going to serialize the instance ID only

[languid spire]

you dont. JsonUtilty cannot serialize dictionaries

[timber tide]

make it a field (for the ID), or use AssetPathID

[shell sorrel]

would reference all your SO's in one spot shove them all into a Dictonary by name

[wintry quarry]

use a different serializer, or don't serialize a SO

[shell sorrel]

then save that name in your save data

then you can use that to look it up later on load

alos yeah would not use json utility

much better tools for the job

https://docs.unity3d.com/2019.4/Documentation/Manual/com.unity.nuget.newtonsoft-json.html

[timber tide]

you don't need to serialize a dictionary anyway, the mapping of ID to Asset should be known on awake

[shell sorrel]

but yeah the data you are saving and loading should not be the whole SO

but just a regular struct or class inside of it

[reef totem]

I have this peice of code of here that is connected to a 3 button slow, medium, fast but every time I change scenes the variable set force always equals 0 and i dont know why

[thorn iron]

and on the other way, if my Items and Inventories are not ScriptableObject, JsonUtility will not get any InstanceIDs but the actual field (int, string, ....)

[queen adder]

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

public class FrameRate : MonoBehaviour
{
    public KeyCode framerate = KeyCode.I;
    public bool showFrames;
    // Update is called once per frame
    void Update()
    {
        if (Input.GetKeyDown(framerate))
        {
            showFrames = true;
            while (showFrames == true)
            {
                Debug.Log(1 / Time.unscaledDeltaTime);
            }
        }
    }
}

Is there anything glaringly wrong with this or is it a hardware issue? Unity keeps crashing whenever I enable it

[shell sorrel]

well how is this surviving scene reloads

there is not DontDestroyOnLoad or anything

[reef totem]

no

and this script is connected to another game object in the next scene where i want this code to work

[shell sorrel]

well not sure what its even trying to acheive but yeah this would freeze unity

with a infinte loop

[reef totem]

because my first scene has a settings menu wich changes the foward force and but then when i load the next scene it says the foward force is 0

and so is the varible setforce

[shell sorrel]

and the first scene stays loaded the whole time and this object is never destroyed and recreated?

[gaunt ice]

it is expected your unity freezes because of the while(true)

[reef totem]

i mean no i think the script is set in a panel on my first and on the next its set on another game object

is that a problem?

[shell sorrel]

and whats the expectation, when you set it the first time its only on that once instance of the script

if you loaded a new scene, and the old instance got destroyed that value is now gone

[reef totem]

what instance

the instance of the object

[shell sorrel]

like i am not even sure what you have going on

but sounds like it is part of scene one then you load scene 2

[stuck jay]

So uhh, any help?

[shell sorrel]

which would destroy everything in scene 1 if it was not a addative load

[reef totem]

yes

[shell sorrel]

and was it a addative scene load?

are both scenes loaded at the same time?

[reef totem]

i will show a picture of my code

[reef totem]

i dont evem know what that means

[reef totem]

no is that even possible

[shell sorrel]

so there is your problem

[rocky canyon]

look it up.. Additive scene loading

[shell sorrel]

when you load scene 2, everything in scene 1 was destroyed

so when you return to scene 1, its all back to its defualt values

[reef totem]

yes but what if I have my game manager that is a prefab

and I put that script on my game manager

will the values still be destroyed

[shell sorrel]

not enough detials given to know

if you want it to not get destroyed you have to make sure that it will not

so either put it on a object that is DontDestroyOnLoad

or use addative scene loading

https://docs.unity3d.com/ScriptReference/Object.DontDestroyOnLoad.html

[reef totem]

ok

[rocky canyon]

https://docs.unity3d.com/ScriptReference/SceneManagement.LoadSceneMode.Additive.html

[shell sorrel]

when you load a scene, everything from the previous scene is gone

unless you tell it otherwise

[reef totem]

wait i will look into it put just so i know we are on the same page im going to explain it more thoroughly

[rocky canyon]

and yea u can load two scenes at once.. its like putting a drawing with a transparent background on top of another drawing..

it'll all exist (to you) in one place

[reef totem]

here is my setting menu with my 3 buttons wich is connected to that script I showed you previously. that script is sitting on the game manager also ignore the console

as you can see the game object has not changed

[rocky canyon]

simplest solution is to stick it in a DontDestroyOnLoad(); as mentioned above

[reef totem]

ok

thank you

[shell sorrel]

these are 2 different scenes

[reef totem]

i did not know that existed

[rocky canyon]

you'd always have access to it

[shell sorrel]

its not the same object

[reef totem]

does do not destory on load only load once every scene

likewise to void start or void awake

[shell sorrel]

no you mark a whole gamboject with it

and that object will survive scene loads

[languid spire]

no, you have to ensure uniqueness if you need it

[shell sorrel]

there is nothing to prevent you from getting more then one

[reef totem]

can you show me how

[rocky canyon]

DontDestroyOnLoad(this);

[reef totem]

so dont destroy on start is not a function

[rocky canyon]

u can put it in start or awke

[shell sorrel]

well with gameObject

[rocky canyon]

would that not encompass the gameobject too?

this.gameObject then

[shell sorrel]

this is a component, it only accepts a top level game object

[rocky canyon]

or gameObject

[rocky canyon]

ahh gotcha

i need to refactor then.

ive been under the illusion that when u do anything to a component like DDOL the gameobject just go with it

[reef totem]

oh thanks

i get it

[rocky canyon]

when u load up the scene you'll have a new gameobject and u can uncollapse it and you'll see ur gameobject that u used DDOL on

[shell sorrel]

i might be wrong, it might automatically get the Go

since its signature is UnityEngine.Object

[rocky canyon]

i think it does.. b/c i didnt notice it

[reef totem]

does not work

[rocky canyon]

and i have a few DDOL

[shell sorrel]

but it applies to ta GO not a component

[rocky canyon]

whats setforce?

[shell sorrel]

no do it to the whole gameObject
DontDestroyOnLoad(gameObject);

[rocky canyon]

u want the script/ gameobject

[languid spire]

Don't you think it might be a good idea to go and read the DDOL documentation before trying to use it?

[rocky canyon]

so all ur code sticks around

its not meant for variables like float or vectors

[reef totem]

how would i do that with the game object

sorry about asking these sillly questions

im a very big begginer

[rocky canyon]

he just told u. thats the line u need

it'll not destroy the entire gameobject that the script is sitting on

and then u can remove ur gamemanager prefab from all ur other scenes.. b/c it'll already be there

it'll look like this.. and ur gameobject will be under the DontDestroyOnLoad object

[reef totem]

like this

[rocky canyon]

well.. if ur reference to gm is the gameobject u want to stick around then yes

what is being said.. is to put it in the script OF the gameobject u want to stick around..

then gameObject just references the script ur working in

[reef totem]

i swear i think i have autism

[rocky canyon]

        DontDestroyOnLoad(gameObject);
    }```

this would ^ cause the ControlTower script and the gameobejct that holds it to be NOT destroyed

[polar acorn]

What object is gm

Is it the object this script is on

[rocky canyon]

its weird to call it from another script

in my opinion

[reef totem]

game manager has more than one script

[rocky canyon]

every script attached to that object will be not destroyed

[reef totem]

the the object game manager has more than one script in this case

[reef totem]

ok

[rocky canyon]

u may want to rethink ur setup.. and have only certain scripts on that gameobject

[polar acorn]

Objects are marked DontDestroy. That's why you can't pass in a component

The whole object will be a DDOL

[reef totem]

i think i will call it in the script game manager later on but for now i just want this to work

[pallid nymph]

(I'll just insert my standard "DDOLs suck btw" comment 😅 )

[reef totem]

what is ddol

[slender nymph]

DontDestroyOnLoad

[polar acorn]

There's no better way to make an object persist between scenes

[pallid nymph]

fair, it's just rarely needed to make game objects persist between scenes imo... and makes restarting scenes much easier when you don't have random objects go between scenes

[shell sorrel]

depends on your approach i tend to never use it

tend to have a init scene with all the important stuff i want to keep a around

then that will do addative loads

[rocky canyon]

additive scene loading is gonna be more confusing to him than ddol

[shell sorrel]

i am not suggesting somoene new does addative loads

[queen adder]

toggle on/off framerate count

I think I need an off toggle?

[shell sorrel]

well currently its a freeze your game button

[polar acorn]

It really depends on your scene structure. If you don't do additive scene loading it can be a good idea to have a single DDOL for persistent data like your saves and settings

[shell sorrel]

there is not reason for it to have the while loop

[queen adder]

let me try sans loop

[rocky canyon]

thats how i do it too.. got a preloader scene that does everything and then sticks around for hard references

[pallid nymph]

That (persisting data and settings) tends to not need scene-stuff, so I'd keep it as a a normal singleton or one could use an SO as well

[shell sorrel]

yeah its also a side effect that generally have like 5 or 6 scenes going at a time

[rocky canyon]

i havent gotten that involved yet. but its possible 😄

[shell sorrel]

for both technical and workflow reasons

[polar acorn]

SOs have the problem of behaving differently in editor versus builds, and a POCO singleton doesn't have an inspector to mess with

[reef totem]

update nothong works my player is not moving

[shell sorrel]

find it so amusing how you guys need a acrynom for a regular object

[rocky canyon]

WUTAW

what u talkin about willis

[reef totem]

the variable setforce is 0

even when a new scene loads

[rocky canyon]

is it 0 before u press play?

[reef totem]

no

because it set it in the settigns menu to be 2000

and then i load the next scene and its 0

[polar acorn]

Share the updated code

[reef totem]

wait i have so many screenshots i dont know wich one is wich

sorry

[polar acorn]

ok i got it

its fine i already sent it

[slender nymph]

!screenshots

[eternal falcon]

No

Be mindful, if someone requests your code as text, don't send a screenshot!

[polar acorn]

In your second scene, search t: SettingsMenu in the hierarchy and show what comes up

[reef totem]

here

[faint sluice]

Setforce is private variable, and isn't initialised so by default it will be 0

[rich adder]

did not do it

[polar acorn]

Actually this screenshot also didn't do the first part either

Run the game

[reef totem]

so just mak it public

[polar acorn]

Load the second scene

then search

[reef totem]

how do i search

[shell sorrel]

while in playmode

[polar acorn]

with your keyboard

[reef totem]

i will just send a ss with my game running

[rich adder]

type the letters which will appear in the searchbox

[polar acorn]

Send a screenshot with your game running, in your second scene, while searching what I said to search for

[austere tendon]

I am not sure if this is the appropriate channel for my question but I am having problems with my Light 2D component, it seems like it does not want to affect my grid when put to Global.

[wintry quarry]

#archived-lighting

[polar acorn]

Okay now this screenshot but with the search in the box like I asked

[shell sorrel]

assuming its the target sorting layer is not correct

[austere tendon]

It's put to default which my grid is on but I'll take it to #archived-lighting from here

[reef totem]

where do i search where is the search box im sorry for being an idiot by the way i just cant seem to undertsand

[polar acorn]

Wait there's literally two of them on this object

Why are there two

[reef totem]

idk i probably put 2 by accidnt

[polar acorn]

so fix that

then see

[reef totem]

i removed that one

[faint sluice]

Even after that value will still be 0 as it's private variable which is not initialised

[shell sorrel]

it sounds like they are setting it from logic in there menu

[polar acorn]

and it is supposedly being set to 2000, then resetting on scene load, but it's a DDOL so it shouldn't initialize again

[shell sorrel]

the problem is they unload the whole object and reload it and expect it to be teh same

[reef totem]

still dont work

[faint sluice]

Doesn't look like that from this screenshot atleast

[polar acorn]

Which means there's most likely a second copy in the scene that has 0, and the one that had a value changed isn't the one that's logging 0

[shell sorrel]

well 2 coppies of it there

[polar acorn]

As I said

[shell sorrel]

which means it existed in more then 1 scene

[polar acorn]

There's two copies of it.

One has 2000, one has 0

You want there to be one instance of this. Ever.

[reef totem]

so the ddol makes it so i only need one game manager

[faint sluice]

Not a single method is called from anywhere that sets value from outside

[polar acorn]

https://gamedevbeginner.com/singletons-in-unity-the-right-way/

[reef totem]

because i used to have one game manager for each scene

but now with this ddol i have 2

[polar acorn]

UI callbacks don't show up as references in VS

[shell sorrel]

well your whole problem is you are acting like each game manager is the same when they are not

[polar acorn]

So read the thing I sent

[cinder crag]

im having this problem when crouching , the charactercontroller center goes up as it supposed to but my playerobj stays the same and im not sure how i can pull the playerobj abck up and make the player scale to 0.5 when crouching and back to 2 when not crouching
