then press Attach to Unity on the top

#

and start your game, play in unity, run it until this line is hit

#

debugger will break and you can look into whatever you want in your code

#

read what buttons do on the top debugger panel

all those step over, step into

Might want to have a look at the Microsoft manual on VS debugger.

#

It's not very easy to understand just from discord messages

there were no nulls

hover your mouse over every variable

on that line that throws

hasty wave
ashen yoke
#

throws a null ref exception

#

its called throw, theres an operator throw in c#

# 
throw new ArgumentNullException();
cosmic rain
ashen yoke
#

most exceptions you encounter that arent NullReference are added by programmers, NullReference is thrown automatically, in any case, if its still not null, then you can add a conditional to the breakpoint

#

right click the red circle > Conditions and type into the field data == null and press enter

hasty wave
#

oh I found the null... what the-

#

It happens when I stop the game

ashen yoke
#

when you are exiting playmode?

hasty wave
#

yes

ashen yoke
#

that is expected, you should add case to handle that

hasty wave
#

uhm... how? I'm quite a beginner in handling this stuff

cosmic rain
#

You probably subscribe to some event that is called when the game closes and the object is already destroyed. You need to unsubscribe from it properly.

#

Or avoid invoking it at that point.

hasty wave
#

uhm can I put an if statement where it checks if its null? transfer the data if it's null?

ashen yoke
#

ill write up a gist that can be just dropped into the project

Is there a good way of determining why a TextAsset won't load through Resources for a specific end user - when it works for the majority of users? I have this method: https://hastebin.com/share/saqorudoki.csharp
It works for my machine and the other developers, but deployed to a playtester on Windows 10 failed to load any of the files.

I found out that, it's still trying to access the object even tho it's destroyed

Hi all, I'm having a problem with bullets not detecting when they run into a wall. The wall has a box collider (not set to trigger), and a static rigidbody2d, on the default layer. The bullet has a circle collider (again, trigger unchecked), and a kinematic rigidbody2d, also on the default layer. Here is the code I'm using to check for collisions:

        private void OnCollisionEnter2D(Collision2D other) {
            Debug.Log("Bullet collided with " + other.gameObject.name);
            DestroyBullet();
        }
        private void DestroyBullet() {
            Destroy(gameObject);
            // sfx, particle effects, etc.
        }```

don't matter kinematic and static dont trigger messages, you either remove static from wall or change ur bullet to nono-kinematic

do you have Full Kinematic Contacts enabled?

Full Kinematic Contacts enables kinematic to receive events from statics

Enabling Full Kinematic Contacts enables a Kinematic Rigidbody 2D to collide with all Rigidbody 2D Body Types.

hi friends can anyone help me to create script of my fidget spinner game?

silent rivet
#

I'm working with a navmesh agent that could potentially have navmesh obstacles put in front of its path that carve the navmesh bake. This causes the path to sometimes become PathPartial, great. The thing is, I want to make sure that the agent actually continues moving until it reaches the bloackade, but right now it just freezes and stands still. Is this a possible mechanic i can do natively (as in, is there a method or field in the agent that contains the last valid location on the path) or will i need to code that myself?

Yes, Thanks Osmal I am working on this

This happens every time I try to write a concise mini tutorial.. lol

#

Long !code should go in a paste site 👇

#

You are printing the abs value of the angle, remove the abs for better info

#

No, put it in a paste site like i said, and delete these long messages

solar dew
#

Its just debug but i use normal value to transform.Rotate

hexed pecan
#

Okay but why print the abs value? It tells you less about the direction

#

Does the cube have a rigidbody?

solar dew
#

No Rigidbody

hexed pecan
#

Ah you are updating the touch start pos only when you press the mouse down

#

You should use the value from the previous frame instead

#

So that you can calculate the difference each frame

solar dew
#

alright understood

#

let me try

#

still same wobble things!

hexed pecan
#

Because Input.mousePosition is in screenspace, you can't mix those

#

Use centerPos = camera.WorldToScreenPoint(trandform.position)

solar dew
#

@hexed pecan Now for dragging rotation i use transform.Rotate, but i also want to swipe on perticuler direction like clock wise or counter clock wise to rotate object freely by applying tourqe so how can i determine the amout of swipe from this code?

hexed pecan
hexed pecan
#

You can use that with rigidbody.AddTorque, if thats what you want

solar dew
#

Yes Thanks let me try

solar dew
hexed pecan
#

Otherwise it will use an outdated startPos for one frame

solar dew
#

I do this but still snap the rotation

hexed pecan
#

The idea is that the previous and current position will be the same when the dragging starts.

#

Line 53 will also conflict with this, you need to change it up a bit

#

Maybe add a if(isDragging) check just for line 53 in that code

Hey! Currently I have all my Main menu's Characters and Core Managers in one Level. I am at a point now where I would like to start working on different levels that I can start loading into etc. The issue I have is, as it's my first time, I am not sure how to split up my Managers to always be loaded and because I have a few inspector assigned variables, I can't wraip my head around how I would assign these varaibles if they are in a different level?

Some advice would be fantastic

that is what I said isn't it?

latent latch
#

Little sleepy here but for the constraint:

public class Stats<T> where T : Enum```
This applies such that the constraint is the type but now if I made a method of T such that
```cs
public void Method(T enumValue)```
Does this imply that the method accepts values of that enum?
knotty sun
#

yes

latent latch
#

No wait, maybe I'm thinking of this wrong uh

#

ok maybe not then thanks ;p

lean coral
knotty sun
#

you do not assign the return value to a variable

lean coral
#

Oh ! in bossAttack, yeah, I never saw it before, thanks

lean coral
knotty sun
#

well if you were relying on it to fill the bossController variable then it might help

lean coral
#

I put bossController = GetComponent<bossController>(); but yeah, the boss still move when he attack

rigid island
#

no shit, your method of stop is not being called you said.

lean coral
#

Yeah but I don't understand why , could there be a conflict with something?

image.png
rigid island
#

are u sure that animation runs? are you sure the transition isn't skipping animation event?

lean coral
#

Oh idk

rigid island
#

try putting it in the middle, test out a few diff config

rigid island
#

you have to learn how to debug

lean coral
#

I tried yesterday but the debugging was a fail, or I don't under how do, I'll check a tuto later

rigid island
#

debugging isn't hard, you just test out different things

lean coral
#

even with the stop event in the middle, the enemy move

rigid island
#

forget the move part

#

you put Debug.Log inside StopMovement ?

lean coral
#

Yeah

rigid island
#

Okay so its not printing then its not running, if even in the middle it skips it then you have to be sure thats the animation your Animator is playing at runtime

lean coral
rigid island
#

with the enemy selected

lean coral
#

I check it

rigid island
#

looks too long

#

that arrow takes forever to reach slash

lean coral
#

idle from slash ? I have to put the same time as slash to idle ?

rigid island
#

the transition

#

cause Idle and Slash seem to be playing at the same time

lean coral
rigid island
#

Only transitions do that

#

yeah dude

#

you're skipping half the clip

#

your transition is too long

#

you see your whole IDLE goes into Slash

#

your animation event is skipped

lean coral
#

Ohhh

rigid island
#

Idle to Slash should not having any Exit Time

lean coral
#

so I have to put 0% ?

rigid island
#

no

#

Uncheck Exit time

#

it should fix it

lean coral
#

they are no exit time

rigid island
#

when then fix the clips

#

transitions, make the sides shorter for idle

lean coral
#

Has Exit time is already Uncheck

rigid island
#

I get it but transition is still too long

rigid island
#

or move the blue arrow small

#

make sure its almost 0 so its instant

#

and not skips animation keyframe

hexed pecan
rigid island
#

🍵

lean coral
rigid island
#

you changed the Slash to Idle ?

#

also at least now the method is running no ? stoopping

hexed pecan
lean coral
#

I put it to 0 and he just don't attack anymore for slash to idle

rigid island
lean coral
#

Yeah, I'll try something

rigid island
#

these two running at the same time

#

thats not right

lean coral
rigid island
lean coral
rigid island
#

i said the problem was idle to slash

lean coral
#

ahh

rigid island
#

not sure why u touched slash to idle lol

lean coral
#

Yeah I can't find how to solve it

rigid island
#

also show the new setup for your animation event keyframes

latent latch
#

How janky does it sound if I make all instant effect sources (damage, mana drain, stamina drain) independent from the ability/attack instance (the controller for which these effects are applied)? Previously I had them tied to the instance of the attack, but when working with upgrades and modifiers it makes more sense to have them separate from the controller. Unfortunately it makes a lot of extra assets on the editor as I need to make a new asset instance for each little damage effect when creating them via SO.

lean coral

Thanks so much for you're help bro

# latent latch How janky does it sound if I make all instant effect sources (damage, mana drain...

It really depends on what you want. Having to much ScriptableObject is most of the time a pain, however you can alleviate the issue by making a good editor. What I am afraid of when I see that you want that, is that you might not use ScriptableObject correctly (in my opinion). They should not be mutable. This way, the concept of ability A is the same accross all your game. If you want to have a modified ability, than you would have ability A+ or ability A (Effect 1, Effect 2). In other words, you should not modified what ability A is at anytime.

latent latch
#

They are immutable, it's just that I have Ability A (immutable) with Effect1, Effect2, Effect3, which are all unique assets to that ability

zinc badge
#

why when i have collider and nav mech agent on same object, it makes collisions with other objects register twice. When i disable nav mech agent, collisions register how expected. i tried to make the nav mech agent radius smaller but still it does what i said.

latent latch
#

I think the problem that it seems smelly is that I can't jam all these SO assets into their own single file as well

#

because of editor reasons

Imagine I have a List<Collider2D>, and I want to make a method in List<T> that lets me do some operation specifically to whatever is at index 0 at the time it is called. And say this method is unique to the type that is held (Collider2D). Is there a way to do that?

#

I have my own class I am writing, I'm just asking like this for simplicity

night storm
steady moat
hard viper
#

idk, I want to make like a method in List<T> that takes in a generic action, which can be specified once class has a concrete instance.

#

List<T> has no idea that T would have a .bounds property

night storm
hard viper
#

and the goal of the action is to mutate the entry that is there

latent latch
hard viper
steady moat
hard viper
#

I guess I should probably just make a concrete derrived class, and be done with it...

steady moat
hard viper
#

yeah... that is probably the smarter way. ty

hard viper
#

ok, this turned kind of awkard

#

i think I’m going to make a static method in the held class to make an action and tie it how it needs to be tied.

latent latch
#

Rewriting some of my classes for the sake of it:

  public class Stats<T> where T : ValueModifier
  {
      Dictionary</*T EnumType*/, List<T>> enumDictionary = new();
  }

  public abstract class ValueModifier
  {
      //No base enum implementation
  }

  public class AbilityValueModifier : ValueModifier
  {
      AbilityStatEnum enumEntry;
  }

Trying to figure how to couple my Stats class with a type of ValueModifier with ValueModifier being composed of a float and an enum type and value. I'm assuming ValueModifier needs a constraint too for the enum type? I don't know why this seems so difficult to resolve.

gray mural
latent latch
#

An example is if the constraint is AbilityStatEnum, which has values Damage, Speed, Duration, then the dictionary in Stats would be as:
Dictionary<AbilityStatEnum, List<AbilityValueModifier >>

#

In the constructor I'd have something like

foreach (T enumValue in Enum.GetValues(typeof(T)))
{
    enumDictionary.Add(enumValue, new());
}```
#

to grab all enum values as keys

gray mural
#

every enum has its unique type

#

you cannot store different types in a single dictionary

#

you'll have to store them as Types

#

so

Dictionary<Type, List<T>> enumDictionary = new();
latent latch
#

I mean the values would be the key

#

of the specific enum

#

which I'm grabbing in the constructor foreach there

#

Maybe the idea is to give ValueModifier<Enum> constraint or something

gray mural
latent latch
#

Not too sure what you mean. It should always be a single type depending on the constraint, unless you mean generic types don't work with dictionaries here.

gray mural
latent latch
#

Yeah, but what I'm getting confused with is how I'd grab the Enum type from T, which I'm assuming I can't and that I need another constraint that's specifically that enum

#

because if I set the constraint as AbilityValueModifier, I should know the dictionary key type would be AbilityStatEnum

gray mural
#

you already have a reference to the AbilityStatEnum in your AbilityValueModifier class

#

and you cannot access it as a key for your dictionary

#

the only thing you can do it change your class

#

no, actually you cannot

latent latch
#

Ultimately the goal is that I have a Stats class that can take in a type of StatModifier and that the Stats class maps each enum value specific to what that StatModifier has declared

gray mural
trim rivet
#

Anyone know if there is a way to read SO data while in the editor, for use in editor scripts ? I only know of Ressource.Load but that's for runtime use. Does a similar method exist for editor use?

gray mural
#

it can just be a list of lists then

#

or just a List<T>

latent latch
#

I just need some lookup

#

So when I do a search for all Speed modifiers I can just plug in Enum.Speed

gray mural
latent latch
# 
  public class Stats<T> where T : ValueModifier
  {
      Dictionary</*T EnumType*/, List<T>> enumDictionary = new();
  }```
Would be a list of ValueModifiers
#

Stats is just a manager type for a bunch of different types

gray mural
#

well, Speed is YourEnum's item?

# 
enum YourEnum
{
    Speed
}
latent latch
#

Yeah, and I'd get a list of all modifiers that are also of enum speed

gray mural
latent latch
#

I have a lotttt of stats which is why I'm using a dict

gray mural
#

your logic seems quite strange to me

latent latch
#

I do like making things difficult for myself. I'm already thinking I need some covariance because why not.

#

assuming I want to give value modifier a constraint

gray mural
latent latch
#

You can plug in enum values in a dictionary

#

assuming it is of a single type

gray mural
#

The possible solution is to make a method that find enums by its name GetEnum(string name)
And your dictionary'll be Dictionary<string, List<T>> enumDictionary then

latent latch
#

enums are just int basically under the hood

#

strings can work too but enums are the way to go

#

c# a little janky though so I do see a lot of string lookups lately

gray mural
#

ok, if you want another variant, you can use Dictionary<Type, List<T>> enumDictionary as I've mentioned earlier

#

but it's more complicated and I don't think it's better than with strings

latent latch
#

Yeah, type would work too. Honestly I've already had the class written, but the data wasn't as coupled as I wanted.

gray mural
#

enums are specific and you cannot just make Dictionary<enum, List<T>>

#

I would consider using strings, it's safe if you make sure the key is enum's fullName

#

this way no enum'll appear in the list more than once

latent latch
#

I'm pretty sure just extending each class out would suffice too, but I can't see why this is so difficult rofl

#

Such that I have AbilityStats w/ AbilityModifiers

Anyone know how to get the scriptable object using AssetDatabase loading? I would like to read some data from a SO at a specific filepath

image.png
leaden ice
#

Don't use it

latent latch
#

what's the return type

leaden ice
#

And use the generic version of LoadAssetAtPath

#

So you can assign it directly to a variable of your specific SO type

#

GetComponent is clearly not correct here since a ScriptableObject has nothing to do with GameObjects or Components

trim rivet
#

Oh I see. Thank you tons, but I'm doing this now and it is definitely not reading the correct values 🤔 (no errors though)

image.png
leaden ice
#

What would the "correct values" be and what's happening instead

#

How are you even checking?

trim rivet
#

Actual values are 5 and 4, correct would be 4 and 2. I am checking using ShowNonSerializedField via naughtyattributes and then debug drawing the box with the values

leaden ice
#

Well if they're not serialized they won't be saved in the asset

if I use delegate -= function, how does program know “I’m looking for X until I find a match to remove.”

#

because I imagine you would never be able to do delegate += with a lambda expression, with any hope of -= to remove it. or am I incorrect?

knotty sun
#

correct, you cannot remove a delegate added via lambda

hard viper
#

ok, so if I make
void MyFunction() { }; and += it to a delegate, how does my program now know how to -= it?

lean sail
knotty sun
lean sail
#

Not sure if that implementation is public

hard viper
#

the kind of answer I’m looking for is: how do delegates identify matches for -=

knotty sun
#

basically Class->Instance->Method

leaden ice
leaden ice
hard viper
# leaden ice By reference

so it’s like a reference to the object, but since it is named, it’s like the class has a static reference for that method?

leaden ice
#

MyFunction is a reference to that particular method on that particular object instance

hard viper
#

gotcha

leaden ice
#

Unless it's static of course but then it's just the global static method

hard viper
#

so if I want to use -=, i need to make sure I match the reference later to match

leaden ice
#

Either way it's a reference

#

Yea

I do have a question based on the specifics of what I'm trying to do.
I have:
Class1Base
Class1 : Class1Base
Class2<T> where T : Class1Base { T class1Instance; }
Class3 (has delegate)
I want to (un)subscribe a function to Class3 that: looks at a specific instance of Class2<Class1>, and calls a specific method in the class1Instance (of type Class1). The specific instance referenced by class1Instance changes

#

I could do this by making a specific concrete derived class of Class2<Class1>, but I feel like that isn't very clean (because I plan to do something like this again)

ContactState is a base type that holds information for grounding, slope normals, isTouchingLeftWall etc.
ContactStateManager<T> where T : ContactState, this is a class that holds a currentContactState and lastContactState.
Some ContactStates are derrived classes (eg PlayerContactState has bools for onJumpableGround, onSlipperyFloor etc)
PlayerContactState has a function to add new information into the contact state on a collision callback, which is something that the base ContactState class cannot have

#

I want to make sure ContactStateManager<PlayerContactState> can subscribe a function, so when we have a collision callback, the currentPlayerState gets updated

hard viper
knotty sun
hard viper
#

I want to (un)subscribe a method in whichever thing is composed, because the instance referenced by currentState gets moved around

knotty sun
#

does not matter

hard viper
#

and I want to avoid subscribing the instance of the currentState,

#

I want to make sure we look into whatever the ContactStateManager property currently points to for its current state, if that makes sense

#

and the generic ContactStateManager<T> has no knowledge of exactly what type of ContactState T is

knotty sun
#

ok, sounds like you need to keep your own reference to what is subscribed and then check that

hard viper
#

well, I'm trying to figure out how to do that most cleanly, without messing with the generic

#

what I'm thinking of right now, is to make an extension method specifically for the concrete ContactStateManager<PlayerContactState>, so I can specifically subscribe the right instance

Hey folks. In an attempt at spreading out AI processing over multiple frames, I'm moving away from each NPC processing their own Update() call, and leveraging a master object to selectively call each NPC's Update() in a distributed manner. However, I just noticed the list of NPCs consists of the GameObjects, not the NPC AI component attached to the GameObjects. I'm worried the performance hit from calling GetComponent every critter every update will make this a futile effort. Is my only recourse to create and manage a second list of the underlying components I wish to call update on?

knotty sun
#

why not just use a list of the components in the first place?

lean sail
exotic aspen
#

It is all my own code, apologies for text having limitations for conveying ideas :/ When an NPC is instantiated I add its gameobject to a list, and that list is what gets used everywhere for higher level display and management. It is also used for saving and loading.

knotty sun
#

why, just add the correct component to the list
component->gameObject == trivial
gameObject->component == not trivial

exotic aspen
#

I didn't realize the hit from grabbing the gameObject from the component was much less than vice-versa.

#

Thank you for that

knotty sun
#

of course all components have a .gameObject variable

exotic aspen
#

Saving the gameObjects made sense when I was trying to export the lists to JSON for saving in a single call. But that all fell apart at some point and I did it manually anyways haha... I never went back and thought about revisiting the list model. This shouldn't be too hard to refactor then.

#

1000 entities doing circlecasts for engagement is just brutal. I'm turning engagement checks on/off by zones now, and have optimized the physics layers being used for it, so now the next step is to split up the AI calls and distribute them more across frames.

young moon
#

Hello. What would be the most efficient way to call an animator bool to be true on a lot of objects and have them synced up? Doing it through a for loop always makes them a little out of sync.

knotty sun
#

use the same animator instance

young moon
exotic aspen
#

Every NPC in my game has a boxcollider on the same layer. Not for localized physics so much as for AI processing. When doing raycasts or circle casts for selecting NPCs or analyzing engagement, each function loops through, evaluates the faction and type and handles it appropriately. For dense engagements this can mean iterating through dozens of friendly NPCs and ignoring them. I've considered making each NPC's box collider belong to its own layer and adding intelligence everywhere so the casts are only done on the layers of interest. This would seem like a good performance boost yes? Or might adding extra layers to the Physics engine outweigh the extra looping? Just curious what folks might think of this.

I started a 2D project and imported a template. I decided to delete that project and start over, but I cant import my template now. I open it and select my project, but it just launches the project without importing any files. Anybody know how I can fix this?

fleet furnace
exotic aspen
#

The layers have all interactions disabled with everything. I just wasn't sure if there would be a performance hit from the base adding of layers to the platform.

fleet furnace
#

But to be honest for spatial quarries using(/abusing) the physics engine like this is not recommended.
It will definitely work for smaller games no problem. But if you are going for something truly big I think you need to invest a day/two into implementing a quad tree (/oct tree)

fleet furnace
exotic aspen
#

Ok, great to know.

hard viper
#

you need to store 1 integer for the whole layer mask, and your CPU will perform operations on the whole integer

exotic aspen
#

:nod:

hard viper
#

whether you use 5 of the 32 bits, or 32 of 32 bits, the processor still needs to do the operation with the whole integer

exotic aspen
#

Does the optimization I described seem like a fair approach?

#

Rather than having all NPCs be on the same layer, and having to post-filter the circle-casts...just assign them all to individual layers and filter on the cast itself?

hard viper
#

layers help you filter out irrelevant collisions

#

lets say Goombas are on an Enemy layer, and Enemy layer interacts with Terrain layer, but not Enemy layer.

#

if I make a giant death ball of 500 goombas on one spot, on a ground tile, then your game will create 500 collisions for goomba-floor.

Well, these collisions aren't used dynamically.

#

They are a way for the AI to determine who is close.

#

All interactions are handled from script via casta.

hard viper
#

if you do NOT use this layer filtering, then the game will generate 500^2 = 250,000 collision callbacks for all the goomba-goomba collisions

exotic aspen
#

Yes I understand the fundamentals from a physics engine standpoint. Its more about how to best optimize using physics for AI. I've also experimented with distance calculations between every NPC to every other NPC, but that seems very wasteful compared to casting.

hard viper
#

if unity's physics engine is running, then it WILL try to calculate it

#

unless you actually take it out of simulation, or don't simulate

exotic aspen
#

Yes but I have all layer interactions disabled in the matrix.

hard viper
#

oh, then layer is just an integer between 1-32 that you can use for whatever purpose then

#

especially filtering on casts

exotic aspen
#

:nod: yeah I was more worried about some kind of overhead that wasn't obvious I might incur.

hard viper
#

but using gameobject layer isn't the smartest way to do this, because it has limitations

exotic aspen
#

Circle casting 200 NPCs every 100ms was bringing me down to 30fps.

hard viper
#

I would make a component or something to keep tabs on everything

exotic aspen
#

I've added a sub-object to the gameobject that holds the box collider with the layer.

hard viper
#

when you circle cast, do you want to filter by layer?

exotic aspen
#

That was the whole point of this conversation haha...

hard viper
#

I would use layers to help sort things by general type of what should interact with what

exotic aspen
#

Originally every NPC had a sub-gameobject with a box collider component on it on the "NPC" layer. Then when doing circle/ray casts I'd get every NPC and filter in a loop by Faction or Type.

hard viper
#

this way you can call Cast/CircleCast etc and filter effectively using the layer

exotic aspen
#

My optimization was to assign each boxcollider to its own layer ie, Player1, Player2, Player3... and filter on the cast itself

hard viper
#

I do not think that is helpful

#

unity's casting methods already filter by what things are in the vicinity

#

it first checks bounds to roughly determine what colliders are even relevant for a cast query

exotic aspen
#

In example 1 I might get 20 friendly NPCs and 4 enemies. I then need to loop in code to sort them after the cast.

#

In example 2, I only get the 4 enemies.

hard viper
#

layers are primarily a means of prefiltering and optimizing physics queries, like casting/collision/etc

exotic aspen
#

Yes, hence why in example 2 I only get the 4 enemies I am interested in...

hard viper
#

but you usually want to filter by gamelogic. not by proximity

exotic aspen
#

We are saying the same thing.

#

Engagement is typically done by proximity though?

#

I wish for my NPCs to only engage if they are sufficiently close to an enemy and have LOS.

hard viper
#

you mean when you have a big death ball of lots of things colliding?

#

if you do not want those to be queried like that, you want to filter them out with layers

exotic aspen
#

Exactly what I proposed as my optimization.

#

My reason for asking, was concern from the overhead adding more layers to the system might incur that were not obvious. For example every NPC is a rigidbody interacting with the floor (this is a top-down 2D RTS game), and I have observed adding more layers will incur a penalty to the Physics2D friction calculations.

hard viper
exotic aspen
#

No, every group of NPCs...

#

Player1, Player2, Player3...

#

There's only 5 players max.

#

So all of Player1's units would be on the Player1 layer.

#

I apologize if that wasn't clear.

hard viper
#

that wasn't clear

#

I would do that

Hey everybody, I have an array of Vector3 that forms an outline. Each Vector3 has two neighbours that they are connected to. But my array is not ordered. So my question is: What is the name of the algorithm/approach to order the array and pass it to my lineRenderer? All Vector3 are on a grid position if that helps. 😄

So I have this code that is currently only used to enable and set Dynamic Resolution on game start (or through console).

https://hastebin.com/share/vafotaweyu.java

Issue is, the LoadSettings method always results in a black screen.

When I use the console command in order to manually apply it, it works properly, and both should use the same methods, am I missing anything?

Console Command Behavior:

  1. pp set gfx_drs_enabled 1 (default: 0) -­­> BLACK SCREEN (for some reason is all black but next command fixes it)
  2. pp set gfx_drs_value 0.4 (default: 1) -> you can now see again and the dynamic resolution is applied

I know for a fact LoadSettings() loads them in the same order because of the console output (see image below)
Also, tried to add a delay to LoadSettings(), just to make sure something external wasn't the cause of the issue.

When debugging, occasionally I'll trigger a halt on NullReferenceException: Object reference not set to an instance of an object. Despite having a live VStudio debug session, the IDE isn't breakpointing on this error so I can identify the line number and observe the Call stack. How does one effectively debug these kinds of errors?

knotty sun
exotic aspen
#

I don't see any useful information here? Am I hiding it somehow?

knotty sun
exotic aspen
#

I must not be aware of what that is?

knotty sun
#

Call Stack, which you mentioned above

exotic aspen
#

The Call Stack is only visible in VStudio. Since VStudio isn't breakpointing during this error, its not refreshed.

knotty sun
#

No also in the console

exotic aspen
#

I didn't know a stack trace view existed in the console. Interesting. How does one enable it?

knotty sun
#

Do you have collapse enabled in the console?

exotic aspen
#

I'm clicking COLLAPSE on and off without any visible effect, at least in this stopped state.

knotty sun
#

Collapse off, additional info or stack trace at bottom of console when an error is selected

image.png
exotic aspen
#

AFAIK collapse just hides duplicate entries. But no, I am not seeing additional info for this type of error when I click it. Note that some errors do show additional info and break in the debugger. But this type of error seems different.

knotty sun
#

no it is not

#

Null ref is one of the most common errors

exotic aspen
#

Yeah, hence why this is so frustrating haha. At least I am used to debugging blind in my day job so can usually sort it out. Hrmph.

#

Let me get another error going. Had to reset and try again since we've been talking.

#

Oh..there it is. On the top right is 3 dots, and under that is settings to enable/disable stack tracing. I'd completely missed it being so small.

#

Let me see if that helps.

In this method if there is no extra logic needed, you can return early if there is no hit

i have simulated Celeste's room switching behaviour for the camera. ive done this by making a room prefab which has a cinemachine virtual camera and an Empty called "Bounds" which has a polygon collider. The virtual camera cannot leave the bounds area, and this collider is set as a trigger. Next to the bounds is another Room prefab. So, when the player leaves the first bounds, the camera pans to the camera within the bounds that the player is in now.

The issue is that the players movement doesnt account for this. For example, when leaving room 1 and entering room 2 to the right side, i can stop moving. the player will then be barely visible. or, when i transition to a room up, instead of pausing the player movement and giving me a little "oomph" after the transition, gravity just pulls me straight down again.

How do you guys suggest to fix this? i honestly have no idea where to strt

dense tusk

gotcha. okay, i get it now. putting the return there just makes it so i can do the other stuff outside of the if statement

I'm trying to teach a stick figure to stand using machine learning and my question is what would be the best joint type to use in a 2D space? I believe the only way to set a rotation angle with 2D hinge is by setting the min and max limits (would like to wrong there). The limit approach results in overly stiff movement and sometimes causes the joint to rotate a full 360 to reach the specified limit. Configurable Joint seems to be the best option if it were available in 2D.

lean sail
#

2d joints do look a lot more limited, configurable joint allows you to set a target rotation

i'm trying to make it so the referenced script is forced to call it's StopMethod when the player is no longer looking at the object they are interacting with, however that isn't working. i'm able to save a reference to the previous script, but the code i have now doesn't work and i ain't sure why

#

i have. the methods function properly. the problem is somewhere in the player script, i'm assuming at line 142, as it doesn't call the stopmethod when the previous if statement returns false

#

i know its populating lastScript as i used debug.log to run an if statement by itself to send if it isn't null

#

trying to use an else if() statement doesn't work though, so i'm not sure what the issue is there

#

but i'm pretty sure that would be the correct way to try to do this

#

i'm just not executing something correctly

hexed pecan
#

Lines 137+:cs else { interactScript.StopMethod(); }
I feel like this shouldn't be inside the if statement with TryGetComponent

#

It will currently only detect that you stop pressing the mouse button when the ray is also hitting the object

correct. that is intended. but i'm trying to make it call stopMethod if the ray stops hitting the object, even if the mousebutton is still pressed

# upper pilot Does UnityEvent require to be on MonoBehavior class?

no it is not required in the sense that you can write it in a poco and it wont complain. unity event is so you can easily plug in events through inspector, so if you want to use it for its purpose then yea its gonna have to exist on a monobehaviour in some form. If its on a poco, the class will have to be serializeable then exist on a mono

I dont know what a poco is

that one is an editor error, can likely be ignored by clearing it or restarting unity

What is best way to mimic const (from C++, const SomeClass*) in C#?

#

private readonly SomeClass obj; looks broken IMHO (when working with referencial types, object's state can still bechanged despite the variable being declared as readonly - so what's the point?)

#

because I am still able to change obj.var = ... or obj.ChangeSomeVarInObject()

#

Note that I don't want to make entire class completely immutable. In some context class should have non-const object state but I also want to be able to make its object state const in other cases

hei, i got a quick question, does anyone knows why i have this error in the code?

image.png
#

this is the piece of code

dusk apex
#

It says your index for an element access in the loop was out of range

#

Either vertices or uvs

hexed pecan
#

readonly fields, or properties that have a getter only, can be set in the constructor

#

Or in the initializer

restive turtle
dusk apex
restive turtle
#

oh, right

#

i do start vertexIndex at 0

#

it should not be a problem tho

dusk apex
#

Maybe consider breaking the loop is index greater than length of each array

hexed pecan
#

Is it a Mesh? I thought it was a MeshData object but that doesn't have vertices

restive turtle
restive turtle
hexed pecan
#

Are you absolutely sure that width and height are the same values that you use as meshWidth and meshHeight?

#

Oh also you are accessing heightMap[x, y], so it could be that as well

restive turtle
hexed pecan
restive turtle
latent latch
hexed pecan
#

Honestly showing the whole script(s) whould be easier

restive turtle
#

here it is

hexed pecan
# restive turtle

You use [y, x] as the indices (in heightMap[y, x]), but your width corrsponds to the first dimension and height corresponds to the second dimension

#

Isn't that wrong?

#

If your map is non square then it's not correct

zealous bridge
#

It seems I wasn't clear enough: variables of my custom class should be generally non-const, but I want to be able to pass that object to some functions and not let those functions change data of object. TLDR: Only in some contexts object should be passed as constant (similar to const SomeClass* from C++), but they don't have to be const always. Is such goal achievable in C#?

latent latch
#

You can pass stuff as interfaces which limits the scope of the data you pass (can pass method getter implementations and such)

restive turtle
#

it seems the error is still there

hexed pecan
#

Start by moving heightMap[y, x] into a different line so you know which [] is producing the error

hexed pecan
#

Notice the (System.Single[,] heightMap)

restive turtle
#

i dont really understand why but once i made the height equal to the square it works

#

and now i can modify it

#

maybe it needed to be a square in the initialization? but i dont really get it

hexed pecan
hexed pecan
restive turtle
#

i made the width and the height equal and then i clicked start

#

maybe because im relying on the noise map that i have and it can not be bigger that that one?

#

but it makes no sense cause i can modify it

hexed pecan
#

You should try swapping the GetLength(0) and GetLength(1) instead

#

And keep the map non-square for testing purposes

restive turtle
#

sure

hexed pecan
restive turtle

it shows that error again

it seems that now it works properly, and i dont really know why. i change again getLength(0) with getLength(1 ) and it works with no problem.

#

jesus....

hexed pecan
restive turtle
#

yes

hexed pecan
#

You changed [y, x] to [x, y]

#

Change either one.

#

It makes sense to have [x, y] and width = GetLength(0), height = GetLength(1)

#

Unless you have a reason to have y first

dense tusk
# dense tusk i return with request for aid. https://paste.ofcode.org/p8EkWWhEdvJcQEUxkxLPjn i...

so still having the issue, but i think i've better narrowed down what isn't working. i can save a reference to the previous script into lastScript, but lastScript only has the value if the ray is detecting an object with the InteractScript component. so i think i need to go about saving the reference differently, but i don't know what other methods there are to do this. would appreciate a point in the right direction

hexed pecan
# restive turtle

To put it simply, try this exact code ^ but just change [y, x] to [x, y]

restive turtle
#

ok, thank you very much!

#

i really appreciate it!:)

hexed pecan
#

Let me know if it works

latent latch
# gray mural I don't see why `fullName` isn't enough It looks like this btw: ```cs "Microsoft... 
public class Stats<T, E> 
    where T : ValueModifier<E>
    where E : Enum
{
    Dictionary<E, List<T>> enumDictionary = new();
}

Solved it with a double constraint. Few things that's confusing is that even though T implies E, I still need to add that constraint onto Stats. I think the problem arrives from the fact that enums can't be extended upon or be overridden so I have to use a base implementation of type Enum.

#

and so the usage would be as:

public Stats<AbilityModifier, AbilityStatType> AbilityStats { get; }
public Stats<EffectModifier, EffectStatType> EffectStats { get; }

//IDE will catch this error
//public Stats<EffectModifier, AbilityStatType> WrongStats { get; }
hexed pecan
latent latch
#

Oh do they? As different types too?

hexed pecan
latent latch
#

I've been just remaking my enums if I needed to extend upon them. It's a little sloppy but it somewhat works assuming I know the type.

#

Ah, yeah that makes sense, but I'd probably have to design that for runtime, yeah?

hexed pecan
#

Yeah it probably doesn't solve your issue, just thought I'd point it out

dense tusk
#

i've copied everything into a new project and it still aint working. at least now i know it's not just a corrupted project and i am doing something wrong.

dense tusk
#

so i know what the issue is for sure now. trying to reference the script only works if the ray is detecting something. but i can't get it to work otherwise and i just can't figure anything else out, not even with chatgpt, so for now i'm just gonna make it so the player can't move or look around. only compromise i can think of for it to not get screwed up

cosmic rain
#

You have some messed logic with the nested of statements there.

#

Something you have been pointed out by Osmal, but it seems like you misunderstood.

marble wasp
#

this is gonna be super specific but does anyone know of a way to completely ignore colour in a texture? not just turning it into greyscale but treating it as if the base colour is white

#

or rather a material

cosmic rain
marble wasp
#

for example taking image 1 but having a seperate camera see it as image 2

image.png image.png
#

i essentially want one camera to see a different material than another camera does

#

but i don't think that's possible

cosmic rain
#

If you want to specifically condition on a color, you'd need a custom shader for that.

cosmic rain
hexed pecan
marble wasp
#

urp and a custom shader that renders shadows as crosshatching

hexed pecan
#

Yeah was about to say, replacement shaders are possible with BiRP

marble wasp
#

it's just wildly inconsistent depending on the uv for some reason

hexed pecan
#

In URP and HDRP you need to use a custom render pass, as far as I know

#

I implemented thermal camera on Builtin RP some years ago but didnt make it for HDRP yet, but it should be possible

marble wasp
#

so i could apply a render pass to one camera that throws out the base colour?

#

i've not delved into shader passes yet

hexed pecan
#

You could also just swap the material for the object just before the other camera renders 🤔 that could be simpler in your case

marble wasp
#

ideally i could just swap the base colour between its set value and 255,255,255

#

then i wouldn't have to add any additional materials for each new object

hexed pecan
#

Yeah true

marble wasp
#

i've never delved into render passes though, will be a learning curve i reckon lol

thorny juniper
#

Hi there I was wondering how could I add a double jump and a dash to the 2d platformer microgame

marble wasp
#

actually yeah i could use replacement shaders to just swap between the original shader and a copy of the shader that doesn't accept base colours or textures

hexed pecan
marble wasp
#

it'd be most of them

#

all wouldn't hurt either

hexed pecan
#

Then I'd say look into custom passes 👍

marble wasp
#

just from skimming over the documentation shader replacements do look like a good bet but are they only functional for built in?

hexed pecan
#

Yeah they are only for builtin rp

marble wasp
#

damn

#

woulda been good

hexed pecan
#

Yeah, they were pretty convenient

marble wasp
#

guess i'm diving into render passes then

marble wasp
#

i found this, might try it

image.png
#

seems too straight forward

#

although i'd have to get an array of every material or make it get the material of whatever is in the camera's view which doesn't seem performant

#

although i could do a sphere cast

#

yeah that might work

Could also stencil it and render the scene twice with different layers rendering

Not much different, you just use events in SRP

marble wasp
#

can i still use it as a script attached to the camera? the render pass is a bit over my head atm

Sure, it doesnt matter where the script is as long as it runs

#

IIRC you want to subscribe to one of the beginXRendering events

marble wasp
#

yeah onbegincamerarendering seems right

marble wasp
#

okay so it works but i can't figure out how to isolate it to a single camera

#

i assumed i could pass a camera into the function since it has room for one but it doesn't appear to work like that

i just need to insert it before and after the highlighted camera

Yeah, I'm trying DOPunchScale for this but.. it's .. not quite right.. but I don't have the eye to see what

#

easings.net and DG documentation have been up nearly 100% of this exercise on my other monitor 😛

leaden ice
#

To use in DotWeen you do something like .SetEase(Ease.OutBack) on your tween

modern creek
#

Sorry, my question might not be clear. I know exactly how to tell dotween what to do.. but I'm bad at figuring out what eases/timing/coefficients for these tweens would look good. 😛

leaden ice
#

oh

#

That's more of an art than a science I guess. I usually just try a bunch until I like one

modern creek
#

that's using a DOPunchScale.. but it's like.. not "settling" fast enough and it's seeming to settle on the wrong scale? I dunno. It's.. just coefficients on the tween but I cannot for the life of me get it to look right

#

DOPunchScale punches the scale to the destination and back again so .. i dunno if i should use it at all, actually.. Maybe I want to do two overlapping tweens on scale - one that's punching "around 1" and another that's growing it from 0-1 at the same time. Although I'm presuming that DOTween is gonna be able to figure that out

Hello, i was wondering is there a reason that stuff like DrawWireDisc is part of the Handles and not Gizmos?
If i am correct Gizmos can be used in a build too but Handles only in editor?
I think it would be nice to have OnDrawWireDisc also work in a build

modern creek
#

Turns out I was making it more complicated than it needed to be. Ease.InBack and OutBack pretty much gave me just what I needed, with a little tweaking to an intermediate step

If you guys use ChatGPT I setup the "How would you like ChatGPT to respond?" part of the Custom Instructions with the following:

Chat GPT should always respond with code examples when asked a coding question. I don't ask just to know what you think, I want actual examples. I don't care how complex it may be. I pay for this service, I'd prefer not to have prompts wasted with barebone answers.

It has been providing much more concrete answers and examples since I've done this.

latent latch
#

Last thing you want to do is make chatgpt angry

crimson agate
#

It's worked really well! I was refactoring code and it kept saying it was a lot of work. Once I put that instruction it's just been flying through everything without hesitation

night harness
#

ChatGPT isn't really used here

#

Since it's not a reliable source of support

crimson agate
#

Not for beginners I'd agree. But it certainly is for people that can guide it.

night harness
#

It's really not

#

ChatGPT inherintly does not know how to program

latent latch
#

it does a good job reading back the vulkan documentation that I love to neglect

crimson agate
#

Yea, I have nothing lol A blanket statement like that is just so bizarre.

#

Thing has no problem setting up builders, factories, strategies with little push. Just a basic here's my code, I know a builder would be better, show me. It's bizarre not to think of it as a useful tool to increase speed of workflow.

The thing has no problem providing you a weighted reponse based on a uncomprehensible amount of scraped data. At the end of the day it's a storytelling engine. It's giving you what it thinks is the best answer, And the "best answer" does not have to be true in any capacity.

When it gives you code it isn't because it understands how C# fundamentally works and implemented the request, It just gives you as close to similar code as possible that it has an explicit connection to the words you asked it about

crimson agate
#

Um yes. That is fine 90% of the time. If you're not a beginner you'll recognize the other 10%. I get it though, purests only. No problem.

I'm going to be using the 2D lighting in my project. However, I am wondering if I should apply this first before anything when starting the project. What I'm asking is if there are issues installing lighting later, and if starting at the beginning is the best action to do.

and if you don’t know what you are doing, then you have no ability to correct the mistakes that chatGPT will inevitably produce

#

neither target demographic is well served by this

crimson agate
hard viper
#

chatGPT doesn’t really know anything. it just puts things together with what looks like proper syntax because it specializes in language

leaden ice
hard viper
#

it doesn’t actually know what any given line of code does, it doesn’t know how it fits into any part of the program, and it will actively bullshit you and tell you it’s correct

crimson agate
hard viper
#

I remember you can ask it for a 60 card yugioh deck, and it will give you a 45 card deck with half of them being made up. and if you ask it about the made up cards, it will return card text that sounds like a real yugioh card. But that isn’t a real card

#

same thing happens with code

crimson agate
#

We already know it's bad at math.

#

i have also tried to make it work with pokemon strategies before. it just copy paste parts of other strategies that have been out, and mashes them together.
It will recommend combos of pokemon that make no sense together, or tell you to run a pokemon with moves/abilities that it doesn’t learn

#

but if you knew nothing about pokemon, it sure sounds right

#

it will also tell you how to play the strat, while making up parts that contradict what was there before

#

it cannot do logic

#

it’s specialty is language syntax

crimson agate
#

yes, which programming is

hard viper
#

is not, you mean

crimson agate
#

and again, a tool is only as good as the person who uses it

#

you could have provided it all the pokemon data and the ruleset instead of hoping it knew

hard viper
#

a good programmer won’t use chatGPT

crimson agate
#

I mean if you can't find a use for it, then it's not a big deal

hard viper
crimson agate
hard viper
#

because you argue that you can only get a logical outcome if you provide all the background knowledge of a particular gigantic topic

crimson agate
#

You're not using it to it's actual capability and you just want it to work perfectly out of the box. It's funny really.

hard viper
#

which means you can only expect it to create good code if your prompt contains years of explanation of basic logic

#

then explain what the actual capability is that causes chatGPT to output good code, that saves more time than it costs to fix

crimson agate
#

That's false man, you don't need perfect code lol you're talking like you want to be able to say design me the final fantasy 8 battle system. Provide me all code and tell me how to hook it up. It's just unrealistic.

hard viper
#

that’s literally how people use chatGPT

crimson agate
#

Yea but that's not a good way to use it

hard viper
#

either code from one language goes in, expecting output in a different language. Or requesting brand new code to do X

crimson agate
#

So the way I use it is mainly for refactoring and I don't take it at face value. I might upload one of my scripts and ask it if it thinks there's a better or more efficient way to do something, and then I'll research that to see if it's true.

A lot of these complaints really are giving me gpt 3.5 vibes tbh and not 4+

Heyo, anyone has an idea why unity tells me my meshcollider mesh must have at least 3 distinct verts even tho the mesh is working fine? Using linq also tells me the verts are not distinct and returns a distinct count of 1 (Debug.Log($"Verts: {verts.Length}, Distinct: {verts.Distinct().Count()}");) ... The mesh is generated using a compute shader

hexed pecan
#

It kinda sounds like the mesh is fine on the GPU side (used for rendering), but not on the CPU side (used for physics)

#

I haven't done that myself, but maybe you need to sync the mesh data to the CPU somehow

dapper rover
#

Same results when logging the first 1000 verts, they are all at 0,0,0

hexed pecan
#

How are you reading back the vertices etc. from the compute shader back to CPU?

it is detecting the right camera but the wrong cameras still swap it for some reason

#

they shouldn't render at the same time, they're completely seperate parts of the stack

#

oh wait the default colour isn't being set properly it needs to set to an array duh

#

now it just sets them all to the original colour even for the camera that's meant to replace damn

#

actually it might be working

#

but not rendering to the camera preview

marble wasp

yeah nice it's just that the preview camera is rendererd seperately to the render texture

it's working properly now, thanks @hexed pecan

jade bison
#

Hi, I'd need help with a model I'm trying to use!

#

Basically my problem is I've got an FBX model that's already in use in the scene and I don't want to reimport a new one or even use an external modeling software again (I'm terrible at using Blender).

#

aaand my objective here

#

is I want to modify every MESH that the project explorer sees inside of the FBX so that they all have their Bounds Center set to 0

#

crucially, it has to modify the actual FBX ON DISK as well

#

Is it possible?

hexed pecan
#

You can load the sub-meshes from the FBX file with AssetDatabase.LoadAssetsAtPath, I believe.

#

I know that modifying a copy of a mesh is possible, but I have never exported it back to FBX

#

Just saved as an asset

jade bison
#

Hmm I'll have to look into that

hexed pecan
#

This is pretty complex for something you could easily do in blender though.

jade bison
#

I mean I did manage to achieve this programmatically but yeah it doesn't change the actual FBX in my assets

hexed pecan
#

I personally save my generated meshes as a sub-asset of a ScriptableObject

#

It's also possible to save it as a prefab

jade bison
hexed pecan
#

Unity treats 3D models as prefabs with MeshRenderer+MeshFilter anyways

hexed pecan
#

As long as you don't change object names/hierarchies in the FBX

jade bison
#

Hmm okay now that sounds good

#

I suppose fixing it through Blender really is the smarter choice, would you happen to know if some place explains the use case of literally just changing the Bounds Center in a simple way?
I'm kinda lost with Blender but I'd rather not ask for someone to walk me through every step on a Unity server lol

hexed pecan
#

In blender, Shift + S -> Cursor To World Origin
Go to object mode, select the object, open the commands (F3?) and search for Set Origin -> Origin To 3D Cursor

#

If you want to set the object's origin to 0,0,0.

#

Also !blender

tawny elkBOT
jade bison
#

might as well ask here as it's not completely Blender-related just yet

#

so erm… I think setting every piece's origin to (0, 0, 0) is what was done already

#

I mean, I believe so; all I can see is Unity's inspector shows Bounds Center with some gibberish values, different for every piece… so I guess I don't want them to have 0 as their origin?

#

That's why I'm confused. All I know is the end goal is to have Unity show (0, 0, 0) as the Bounds Center for all the pieces, but this might be a case of “oh it's the opposite actually” and in Blender that's not what we want~

hexed pecan
#

Why do you need the bounds center at 0?

jade bison
#

The way the FBX was originally exported from Blender (by someone else), all origins were reset (I believe that's the term they used)

#

as such, every child GameObject once imported in Unity had precisely (0, 0, 0) as its transform position

hexed pecan
#

Is the FBX like a 3D scene with multiple objects? And their origins are at zero, not at where the objects are?

#

In any case I don't think you want to edit bounds. Those are used for culling, for example

jade bison
#

idk I'll wanna have moving parts in there and it made sense to me that GameObjects actually appeared to be at their true locations, with the origin gizmo and all

hexed pecan
jade bison
#

So yeah I since changed each piece's coordinates to be that of its associated mesh's Bounds Center. But in return, you guessed it, I figured I needed to recenter every mesh.

jade bison
hexed pecan
#

Yeah Origin To Geometry does exactly the same as adjusting the origin to bounds.center in unity

jade bison
#

Nice! But if I understood correctly, that's not a recommended thing to do?

hexed pecan
#

What's not recommended?

#

I just recommended it 😄

jade bison
#

Of course and thank you for that!

jade bison
hexed pecan
#

Actually you might want to try one of the two bottom options too, see what works best for you

image.png
hexed pecan
#

Though do make a backup of the FBX and/or blend file before you change stuff

jade bison
#

Oh yes of course, I'm not going to change the FBX's hierarchy as that's now where my stuff is pulling resources from!

#

I mean hopefully I won't change it, if I don't mess this up~

jade bison
jade bison
hexed pecan
jade bison
#

sure thing, Imma do it right now, I'll see if it exports the same

hexed pecan
jade bison
#

got it about Blender questions, thank you very much for your help so far!

hexed pecan
#

It's possible that you want to exclude the 'containers' from the selection, but you have to try to see.
No prob!

jade bison
#

OH THIS WORKED SO WELL!

#

massive thanks @hexed pecan ❤️

#

hit F3, type funny stuff, click, export and win :3

#

For future reference, for anyone reading this whenever: the first suggestion of going with Origin to Geometry was it. Centers of mass are interesting but I don't suppose they really correspond to the Bounds, which was my use case ^^

Hey everyone

#

Does anyone know how to achieve wall jumping?

#

The issue is, I'm able to make the 2D box jump from one wall to another back and forth

#

But I want my character to be able to jump along the same wall if the left arrow is held

#

I tried with trial and error

#

But it doesn't seem to be doing much

spring creek
swift falcon
#

Or should I just paste it here?

spring creek
tawny elkBOT
swift falcon
#

Oh ok

#

Thanks

#

@spring creek

#

Ignore the comments, those were there so that the rest of my dev team didn't have to be confused by everything

hard viper
# swift falcon Oh ok

What I do is I have a class for ComtactState which stores and accumulates information about what we are touching

swift falcon
spring creek
hard viper
#

ContactState has things like grounded, onLeftWall, onRightWall, etc

swift falcon
#

It's an empty game object

swift falcon
hard viper
#

ContactState gets populated from EITHER: 1) Collision callbacks, or 2) reading GetContacts

spring creek
# swift falcon

Yeah I figured. I wanted to see where it was though.
So it's only on one side it looks like.

swift falcon
#

Yes

swift falcon
hard viper
#

either way, before you actually issue any jumps, you need to go through and get information for your current ContactState, to know if you are touching a left wall, right wall, floor, etc

swift falcon
#

I should change it to accomodate it that way

hard viper
#

you will want it for enemies too, so you might as well

swift falcon
#

Yeah I can make it a common class

hard viper
#

for wall jumping, there’s a bit that goes into it. are you struggling more with logic of when to do it, or how to make the wall jump happen?

#

eg the physics of the jump

swift falcon
#

I think you misread my question

#

I can make it wall jump between two walls

#

But I can't make it so that the character wall jumps across the same wall if the left key is held

spring creek
#

Well, right now it looks like what you have should work if you're facing the wall. Might be an issue that you change the local scale any time you jump from the wall though
if you want to capture both sides, you probably need a check on both sides.

hard viper
#

you mean chaining wall jumps against one wall?

swift falcon
swift falcon
#

It's a direction issue i think

hard viper
#

separately, the first thing I would do, is rip out all the bools for “isWallSliding”, isWallJumping, isJumping… etc. This should all be one enum because they are mutually exclusive states

#

player movement scripts get super complex, and this will simplify everything dramatically

swift falcon
#

But how do I fix the actual problem where it's not going in one line?

#

Or how do I figure it out?

hard viper
#

your code confuses me in how you split wall jump and regular jump

hexed pecan
spring creek
hard viper
#

wall jump should get called AFTER an attempt to call a normal jump fails. Not just calling WallJump in the main update loop

swift falcon
swift falcon
swift falcon
hard viper
#

i would start refactoring with a MoveState enum. it will help tremendously

swift falcon
#

sure

swift falcon
hard viper
#

enum MoveState { Neutral, Swimming, Jumping, WallJumping, Sliding }

swift falcon
#

alright

#

thank you :D

#

when I'm done I'll tell you

#

if it still doesn't work as well as i want it to

#

but it helps a lot thank you so much, I'll get to it right now

hexed pecan
#

You can still use properties like bool isWallJumping => moveState == MoveState.WallJumping if you want

swift falcon
spring creek
hard viper
#

i inheritted some code from dawnosaur, and I never fully recovered from spaghetti poisonning. Your code looks like that, but less intense. And you should nip it in the bud before the spaghetti monster comes for you

hexed pecan
#

But a state machine would be best, where you don't have to do those checks

swift falcon
swift falcon
hard viper
#

i tried at least 3 times to refactor, and I still could not get it all out

spring creek
# swift falcon what do i use instead?

It depends on what you want. Do you want the local scale to define the x component of your velocity? Seems like NOT what you want. So just don't do that. Use input instead.
If you press left, go left, etc

hard viper
#

the main challenge was him storing a ton of booleans and floats, which made it hard to de-spaghetti

swift falcon
#

i can do that

swift falcon
spring creek
#

But yeah, honestly just simplifying as loup said will make it way easier

swift falcon
#

i will

hard viper
#

for actual wall jump, would personally hard set velocity. directly assigning velocity to a specific number makes the jump arc unaffected by your prior movement, movement in any reference frame, or any inheritted movement etc

#

it is the opposite of how celeste is coded, where I believe madeline’s wall jump obeys the physics of the wall she jumps from

swift falcon
swift falcon
hard viper
#

if you want celeste-like, then you need to apply impulse mode force

#

madeline inherits movement from all sorts of shit that she touches, and the effects all stack

swift falcon
#

i can experiment ig

swift falcon
hard viper
#

this also means your wall jump gets gimped if wall jumping from a falling wall. or is affected by your sliding speed etc. so be mindful.
