Try using Vector3Int as well as passing the actual flags as the second parameter(TileAnimationFlags.PauseAnimation).

I have both the old error and this new one:

Ah

This was just me being dumb

# abstract pelican

There should be a touch binding. You'll have to figure out how to implement that. I think you can get a touch COUNT, so like if there are two, count that as right click?

teal viper
#

TileAnimationFlags is thecorrect enum

hushed spire
#

You right

Been at this for 5 hours don't judge

Alrighty

Just giving same errors that I get in Unity

"Show potentiel fixes"

slender nymph
#

do you have using UnityEngine.Tilemaps in your using directives?

summer stump
#

But still, that would be it

hushed spire
hushed spire
slender nymph
#

ah, so the last error is due to omitting the Tilemaps. part of the type. the enum you are trying to use is Tilemaps.TileAnimationFlags

#

as for the first one, what version of unity are you using?

teal viper
hushed spire
#

checking unity version now

#

2021.1.34f1

teal viper
#

Actually that's correct. You don't need the Tilemaps there since you have it in usings.

slender nymph
#

yeah the enum and method were added in 2022

hushed spire
#

Wow

#

Making a backup before I update it

teal viper
#

2021 lts seems to support it too

hushed spire
#

Any reccomendations?

#

Oh

#

Nevermind than?

teal viper

Why are you on a beta version of several years ago lol?

hushed spire

I make a lot of sleep deprived decisions for quick fixes

This was probably one of them from a previous project

I have the main camera separate from the player, so when my camera moves vertically, the sword doesnt stay in the middle of the screen
how can i make it follow the vertical movement of the camera?

public class SwordController : MonoBehaviour
{
    public Transform swordCursor;
    public Vector3 defaultPosition;
    public Quaternion defaultRotation;
    public float rotationSpeed = 10.0f;

    void Start()
    {
        defaultPosition = transform.localPosition;
        defaultRotation = transform.localRotation;
    }

    void Update()
    {
        if (Input.GetMouseButton(0))
        {
            if (swordCursor != null)
            {
                //Point towards SwordCursor Object
                Quaternion targetRotation = Quaternion.LookRotation(swordCursor.position - transform.position);
                transform.rotation = Quaternion.Slerp(transform.rotation, targetRotation, rotationSpeed * Time.deltaTime);
            }
        }
        else
        {
            // Smoothly move back to default position and rotation
            transform.localPosition = Vector3.Lerp(transform.localPosition, defaultPosition, rotationSpeed * Time.deltaTime);

Aight give me a few minutes for a backup and an update

teal viper
summer stump
#

And 2022.2 NOT supported?

teal viper
#

Anyways, if you can afford it, better to update to latest lts(2022)

teal viper
hushed spire
#

Naaah I aint spending money

summer stump
hushed spire
#

I can afford it if it's free

summer stump
teal viper
#

They often start working on betas earlier than previous lts, so some of the previous version features might not be included.

teal viper
hushed spire
#

2022.3.11f1 good?

teal viper
#

Right, I mean if you're not afraid of breaking changes.

teal viper
hushed spire
#

So how breaking are we talking

#

Oh well I made a backup for a reason

slender nymph
#

probably better off just updating to 2021.3 tbh, less chance of features changing

hushed spire
#

Yeah i'm installing both

#

Gonna use 2021.3 for this project though

#

please wait for me my emotional support coders 🙏

#

Alright, opened with 2021.3

#

well, opening

#

@slender nymph @teal viper Opened in newer version, still same errors

#

trying 2022 now

#

still same errors

#

wait!

#

only 1 error now 🎊

#

Assets\Scripts\DiscoFloorSpeed.cs(12,75): error CS0103: The name 'Tilemaps' does not exist in the current context

#

it works

#

thank you box and dlich, 5/5 stars, kudos

teal viper
#

So it didn't work in 2021.3?

hushed spire
#

2022.3 was successful however

royal linden
#

how do i fix this

image.png image.png
teal viper
#

Nvm.make sure that the index is within the bounds of the array.

royal linden
#

how

#

tho

slender nymph
#

items.Length is 1 index past the end of the array

teal viper
royal linden
#

no#

teal viper
#

Nvm. I'm not reading the code properly

#

Boxfriend is correct.

#

Why are you accessing something with that index?

#

Length is the last element index + 1 if that wasn't clear.
So it's out of bounds.

royal linden
#

so i cant use it?

teal viper
#

You can't use it as is. Why would you do though? What are you trying to do?

royal linden
#

spawn things

teal viper
#

I'm talking about that line specifically

#

What are you trying to do on that line?

royal linden
#

pick a random thing in it

slender nymph
#

well that's certainly not how to get a random object from an array

teal viper
#

Well, that's not how you pick a random thing.

rich adder
#

you need a random number , aka index within that array/list @royal linden

im geting this error

ArgumentException: Input Button Escape is not setup.
To change the input settings use: Edit -> Settings -> Input

with this code

    if (Input.GetKeyDown(KeyCode.Escape))
    {
        Debug.Log("Sup");
    }

but the problem is even with the error poping up, its still working

this is the same script

#

Actually, that's a runtime exception... so no underlining

#

but navarone is correct

#

there is no issue in that code, it doesn't use GetButton, so it won't throw that exception

bright kindle
#

sorry let me explain
this is within my update fucnction and its showing no error during editor but when I start the game, its start giving this error while the game is picking up Escape key

summer stump
#

Make sure to hit ctrl+s in the ide, then clear errors in the console, then hit play again

bright kindle
#

yeah I have it every few seconds

summer stump
#

If the error pops up again, screenshot line 83 of the level manager script

now im getting this error

#

are you like mixing Input systems ?

summer stump

So are you using the new input? The other code was the old input manager

yes new input system

I actually tried looking how to do it with the new

couldnt find

Alright, I have what I assume is a logic issue here. I'm working on an inventory system for my game and this is the codes for the placement of the buttons. Currently I'm hardcoding the buttons to depend on each item rather than assigning an object to that button in the inventory. Everything works except for the setButtonPlacement function, it sets the button as active, but the placement of the button does not go to 0,0 as I'm trying to set it. the InventoryButtons list is a list of "Button" structs. I followed documentation I found online for changing button placement in code but for whatever reason its placing it around -700,-1000. Any ideas or info y'all need to help me?

image.png image.png

# bright kindle https://gdl.space/qoqinokoti.cs

I believe you have to actually enable the input (with playerInput.enabled = true) before you can call ActivateInput or DeactivateInput

Also, on line 83 there is no code. Is this modified from the previous error?

bright kindle
#

yes I modified it. I saw the issue there so I modified it

#

yeah it worked 🥹

#

I had to enable it

#

thanks

#

Start throwing some logging in your code

#

And make sure the position isn't being changed locally

ruby elk
#

I have for everything else besides the last function because theres not much I can change on it besides that position that I can see in the inspector. I know the first line of code for the method is running so its not an issue of it not being called

summer stump
#

I would also say throw in a debug log with the actual position values being set

ruby elk
summer stump
#

There is transform.localPosition

ruby elk
#

Thats my problem then. Perfect I'll see if that works, thanks

#

Yessir that fixed it, thanks y'all

Hey guys, super odd question because I found a working solution to it but I have no idea why the solution works any differently at all but here goes.
The following code works:

if (triggerName != "")
        {
            triggerScript.addTrigger(triggerName);
        }```
However this code returns an index outside of array error(wtf???):
```if (getData.frames[actionIndex].triggerName != "")
        {
            triggerScript.addTrigger(getData.frames[actionIndex].triggerName);
        }```
I know it's really not an important question because I have found a solution but I'm trying to learn and genuinely curious/confused as to what the functional difference is between the two of these
#

(also I checked if the index error was occuring in the trigger script and it wasn't so idek man :/

wintry quarry
#

Also the types of the objects involved are not clear either

olive lintel
#

get data is a scriptable object and frames is a struct contained within it

olive lintel
wintry quarry
#

You'd need to show those types

#

frames seems to be a list or array btw, not a struct

cosmic dagger
#

how is frames a atruct? did you create an indexer for its fields?

wintry quarry
#

I'd guess they're confused and it's an array or list of a struct type

olive lintel
cosmic dagger
wintry quarry
#

It'd be better if you just showed the code

olive lintel
#

I changed it back to the old solution and now it works exactly the same so idek what happened...

#

I think maybe before I was adding 1 to the actionIndex variable or something and maybe I didn't save it beforehand I have no idea

wintry quarry
#

I'd guess you had something else before

#

That being said the first example in your code snippet above is much better

#

It's cleaner and more efficient

cosmic dagger
#

i would've logged the value of actionIndex beforehand, it was probably out of range . . .

slender nymph
#

also unrelated to the actual issue, but rather than checking if the string is equal to "" you could instead use string.IsNullOrWhiteSpace

    public ParticleSystem particle;
    
    void Start()
    {
        particle = this.gameObject.GetComponent<ParticleSystem>();
        particle.Emit(1);
    }
    void Update()
    {
        if (!particle.isPlaying)
        {
            Destroy(this.gameObject);
        }
    }
}```
hey everyone, i'm trying to make an impact system for my weapon. whenever a raycast hits a wall, a prefab with this script is created but i can't see the animation. any reason why this doesn't work?
teal viper
random sand
#

i just wanna ask is there a cheaper way of doing this?

#

there's a delay from when i click to when the animation plays

teal viper
#

Are you sure it's actually a performance issue?

#

If it is, use the profiler to troubleshoot it.

#

One possible issue is if you're spawning many of this particles every frame. This would cause a lot of work for the GC. In this situations it's advices to use an object pool.

Hey, does someone know how can I create a good icon for my app created in unity for Android?

#

Cause in my phone, the icon that I've chosen it's blur

#

And it is not a resolution problem because I have exported it from Photoshop at a very high resolution

unique hull
#

Ive ran into a weird problem with a wage equation that wont return anything but 0.

float payfloat = (((worker.Wage*worker.Level) / 480)*50);

Worker.wage is an int at 100
Worker.level is an int at 1

I ran a debug for those values and that works correctly. But the payfloat never returns anything but 0 all the time.

Anyone have any idea what im doing wrong?

#

It should return ~10 in my books :/

north kiln
unique hull
#

I just did that and it works now. What in the world? , i thought if i didnt type "f" it was counted as that in this case

north kiln
#

No, you are performing integer division, and assigning the result to a float

#

float result = exampleInteger / (float) anotherExampleInteger; is how to do it when you have two integer variables

unique hull
#

Ahh. But i dont need a (float) infront of my wage*level part of the equation?

north kiln
#

As long as one of the arguments is a float, it will perform floating point division

loud dragon
#

I am having problem here as even after adding prefab to the gameobject in the inspector it is showing missing variable

unique hull
#

Ahh gotcha. Thanks alot , good to know for later equations. Save me some headaches 🙂

loud dragon
north kiln
#

Search the scene for that component and check what every one has it assigned

loud dragon
#

i have checked it

unique hull
#

You have no code in the start function that searches / resets the prefab?

loud dragon
#

no

north kiln
#

Can you show the hierarchy when you have searched t:Player_rotation

loud dragon
north kiln
#

Do both of those objects have the Bullet Prefab assigned?

loud dragon
#

no

north kiln
#

Then that's your issue.

loud dragon
#

thanks

#

in the above code my bullet object is just remaining static after shooting and is not moving forwarrd what should i do

unique hull
loud dragon
#

donethanks

vale blade
#

what is a good place to start building a chat interface similar to how you text on a phone? any components I should consider?
my plan is to make a prefab for a message, and then programatically add these to the window. I'm not sure how I'm going to handle eventual scrolling though?
I'm also unsure how I'll handle that some messages are longer than others, so they ll differ in height

gaunt ice
#

not code question
you may get started with scroll rect, content size filter, vertical layout group

amber spruce
#

hey so how do i set like a new key mapping thing

#

trying to make my player be able to sprint

vale blade
amber spruce
#

so in my player controller i want to add sprinting

#

this is the code i have rn for the sprint part

   if (Input.GetButtonDown("Shift"))
   {
      playerSpeed = playerSpeed * 2;
   }
#

will that work for if the shift key is pressed

unique hull
#

That would increase the speed everytime you press the button

#

You need to have a Basespeed variable and a current speed variable.

So when you are pressing shift - the currentspeed would be Basespeed *2 , and when not - currentspeed is basespeed

amber spruce
# 
        if (Input.GetButtonDown("LeftShift"))
        {
           playerSpeed = playerSpeed * 2;
        }
        if (Input.GetButtonUp("LeftShift"))
        {
            playerSpeed = playerSpeed / 2;
        }

i have that aswell

#

oh wait no that wouldnt work

# 
 if (Input.GetButtonDown("LeftShift"))
 {
    playerSpeed = playerSpeed * 2;
 }
 if (Input.GetButtonUp("LeftShift"))
 {
     playerSpeed = playerBaseSpeed;
 }

smth like this

unique hull
#

Id put it in the shift aswell

#

So playerspeed = playerbasespeed *2

#

Just incase something interupts the "Getbuttonup" function later on in your development

amber spruce
#

alright

unique hull
#

Like a menu , or something like that

amber spruce
#

but the part that gets if the button is down or not is good

unique hull
#

Yeah thats good.

amber spruce
#

so yeah it doesnt do anything

#

and i dont see any key for it in the input manager

unique hull
#

Ohh , have you not added the shift key to the input?

amber spruce
#

probably not

#

where would i do that

unique hull
#

Ohh this input system is new. I havent used it im affraid. I useually put in the keycodes instead of the input system.

So either you look up a tutorial for how to enter new inputs into that system or use : if (Input.GetKeyDown(KeyCode.LeftShift))

ruby elk
#

Or you can try and just get a value of that key (0-1) and use that

amber spruce
#

so how would i have it so it plays a certain animation while its active

ruby elk
#

within update,

if(keyvalue == 1 && animationNotYetStarted) {//keydown
doAnimation();
animationNotYetStarted = false;
}

#

the bool is so that it doesnt continually start over and over

amber spruce
#

doesnt it only do that animation once though

opaque jay
#

Hi, I've noticed my code isn't as colorful as when I check out tutorials, what makes my code show in different colors ?

amber spruce
opaque jay
#

I'll check that out :3

Wasnt there like a possibility to set up a default scene that you are loading in when editing a prefab? im trying to find it but I cant

#

Like editing a canvas prefab with a pre-set scene to emulate my other UI

#

hey i have made a small target prcticing game and have done everything but noow its not working properly its when colliding its not getting destroyed and giving points so was asking if someone can somehow help

keen dew
#

Can't help without seeing the code

rocky owl
#

Hello guys, do you know how i can enter in each element of this?

image.png
languid spire
rocky owl
#

from code

#

for assign the data to other object

unique hull
#

Is that an element you have made yourself ?

#

If it is , then you need to add a function to apply the values

short hazel
buoyant knot
#

it seems like a struct they made

rocky owl
#

in a for or foreach?

short hazel
#

Not necessarily

#

You can pass a number directly to access a specific element

rocky owl
#

i dont understand sorry. That's how I'm trying

image.png
short hazel
#

You can't use foreach here

#

Well, you can't use a numerical index if you want to use foreach

#

Just use the item variable

unique hull
#

index outside of the loop , but for is better in this case

short hazel
#

item.Id

rocky owl
#

but for example if the item have id 2 i cant assign the data that correspondent

#

?

short hazel
#

Well what do you actually want to do?

#

Access a single element of your list, to get or set a value, or go through all the elements of the list

rocky owl
#

I have an item and I want only by assigning the id to put all the other values such as description, etc.

short hazel
#

So you need to find an element that has a specific value in its Id variable

#

You can either use for, or foreach for those

unique hull
#

Ahh i see

rocky owl
#

Yes, but I have lists within a list

#

I need acces for example to element 0 and id of element 0

image.png
short hazel
#

There's no lists in lists here

polar acorn
unique hull
#

Theres a few ways you could do this.
I would use a master list with all the IDs and properties already filled in.

Then you run a foreach item (Inventory) Against a foreach Item(Masterlist)
And if they match - set the values to be the same as the master list item.

Or you could use a foreach loop on the items there and use a switch case on the ID's but thats not recommended.

short hazel
#

You do items[0].Id to access the ID of the first element in the list

rocky owl
#

sorry i dont understand too of programation

opaque jay
#

Erjoni, you want to go through all the Id values of your elements right ?

rocky owl
#

yes

rocky owl
opaque jay
#

yup, SPR2 has given you the answer

short hazel
#

For loop, foreach loop can both do that

amber spruce
#

so for my player controller script i have it set the playerbasespeed to 5.0f but in unity its set to 2 for some reason

#

public float playerSpeed = 5.0f;
public float playerBaseSpeed = 5.0f;

gaunt ice
#

editor will override the value in your script

unique hull
#

^

amber spruce
rocky owl
#

Im going to try

amber spruce
#

i guess i canjust edit it in the editor

opaque jay
unique hull
gaunt ice
#

make them private, or just edit them in your editor if you have multiple instances and them will have different speed

Hi, i have made a Programm with whom i can open various Video- and Audioclips and since i need to store these custom made Clips somewhere and need to load them into the Program when i click a Button, i use the Resources Folder at the Moment. Of course, since these are quite a few Clips, i need to order them in a Folderhirarchy. Now i have the Problem, that the Program works in the Editor, but not when builded, i think because Unity turns the whole Resourcefolder into one File, so that the Code adressing the Folderstructure does not work anymore. Now, eventhough i could question now, why Unity even makes such a Code, that does not work when builded, in the first Place, but i just want to solve the Issue and load my Files at the Moment. Is there an

Option 1: A Command to load Files from the Resource Folder with respecting the File Hirarchy / Data Path, or

Option 2: Store Files in another Folder with another Load() Method, so that this Folder does not get turned into a File by Unity when building?

Example of useless Code:
Videoclip = Resources.Load<VideoClip>("Subfolder/Videofile");
// Works in Editor, but not in Build

hey so i have an enum in a static class like this:

public static class Loader
{
    public enum Scene
    {
        MainMenu,
        SceneLoader,
        Lobby,
        CharacterCustomization,
        DemoScene
    }```

and i have accessed its ToString method before like this:
```cs
    public static void NetworkLoad(Scene target)
    {
        NetworkManager.Singleton.SceneManager.LoadScene(target.ToString(), LoadSceneMode.Single);
    }```
which gives the name of the scene, like Scene.MainMenu.ToString = "MainMenu".

i'm trying to use that in another script though and getting compile errors:

```cs
switch (sceneName)
{
    case Loader.Scene.CharacterCustomization.ToString():```

this gives me the error `The type name 'CharacterCustomization' does not exist in the type 'Loader.Scene'` which is weird because it does and also if I remove the ToString it resolves it perfectly but gives the error `Cannot implicitly type Loader.Scene to String` as expected.

what am I doing wrong?
languid spire
#

To start with your first code example does not access your enum.
Secondly you use ToString on an instance of a variable not of the type itself

polar acorn
#

You could store it in a variable and ToString that variable

#

and I think there might be a helper method in Enum that gets the string of a specified value

I feel stupid, this is like the 15th time im setting up ui stuff and now it doesnt work like it did the other 14 😄

I have

  • Event System
  • Graphics Raycaster on the main Canvas
  • Event Setup for the Button

Clicking it does nothing though, I installed the new InputSystem for the first time tho, any ideas what might be missing?

polar acorn
#

(Using the last overload on the page since you have the enum value and don't need to cast it from int)

polar acorn
keen dew
#

Switch cases must be constant values so the approach won't work either way

silk night
#

Yes

silk night
polar acorn
# silk night Yes

So, at the bottom of the inspector for your event system, you should see info while playing about what's currently hovered and selected and whatnot. Play the game, hover over your object that's not responding to clicks and see what your event system thinks is going on

#

You might have an invisible collider/raycast target in front of it

Can you get any UI elements to respond to the cursor, or is it just this one specific one that's not working?

silk night
#

and it reacts to hover & click

#

weird oO

#

well as soon as I put it into UIMainMenuScreen the reaction stops

#

oops, figured it out

#

Ah, I see, your sub-canvas has no graphics raycaster

only the main one does

in this both the objects are not colliding and are bypassing each other and are not destroying

swift crag
#

it's directly poking around in your project folder

#

None of these files will exist on disk in the built game. Everything will be stored in a few big asset bundles.

#

Resources.Load and Resources.LoadAll will be able to retrieve assets that are stored in a Resources folder.

#

These do not load "files". They load assets.

#

If you absolutely must think in terms of files (e.g. you want users to be able to add their own files or editing existing ones), you want StreamingAssets.

#

If you just want to know how many assets are found at a certain path, then call LoadAll and then check the length of the array

tulip tapir
#

How do i:
Array = Resources.LoadAll<Folder>(Subfolder);
Length = Array.Length?
count Folders in the Resource Folder with a Command? Without counting Subfolders wich are further down below in the Hirarchy?

When handling online multiplayer do I need to set up my player controller in a different way? Just curious how it would work..

I just want to make sure I am building my game in such a way that it isn't extra rediculous to add multiplayer support into it. Any advice ? Any videos or recommendations on this? I don't want to build my system in such a way that I can't easily expand upon it and add the multiplayer in the future

For example, I have a sword in my game that is non-triggered and an enemy that is. I have the code on my enemy to detect on trigger and checks if the object is a sword. Gets the script on the sword (or bullet in your case) to check how much damage it did, and removes the amount of health from my enemy

The why is because thats very tough compared to just using python scripts in Unity. If you're using puthon because you don't know C# well @undone stream, you'll need to know C# anyway

I got a Vr headset and im trying to make a 3rd party software so that i can play A "normal game" (not vr game), inside my VR headset,

#

i hope what I am going for makes sense

#

My player is moved around primarily by forces. But if he is on a moving block, I want the block to transfer any of its motion to my player (but I can’t use friction).

valid finch
#

@navarone is netcode for gameobjects good to use? for a 1 vs 1 online situation?

polar acorn
# buoyant knot In my case, I have my rigidbody moving in the reference frame of another object....

So, if your intention is to actually teleport the object, you'd want to set Rigidbody.position. MovePosition is for when you want to set a destination and respect all the physics behind it like collisions and whatnot which can very quickly cause some major jank with a dynamic rigidbody. If you want your dynamic rigidbody to just go to a place, you can set the position of it similar to how you can to a transform, and while it won't calculate physics along the way, it'll still actually move the rigidbody to the target location right away instead of lagging behind by one timestep

buoyant knot
#

that is what I have been doing, but I am getting collision jank, because I can be translating my RB’s collider into another collider

#

idk i wish there were like a joint2D that would just transfer it like a force

#

but all the joint2D I try also block the rigidbody’s own AddForce commands to move it

ruby elk
rich adder
valid finch
# ruby elk Yes you can find some pretty good tutorials online

Alright thank you. From where I am at now.. I have player movement, a play selection system, and receivers run the routes based on the play selected using some waypoints. Lots of just other basic scene setup. I don't think I am too far in to start planning for it

I am not sure if i am supposed to ask this in this channel, but basically I have a game where I have a sprite (square) and I have tried to import a .png of a square but now the square is way bigger, how do i make it so that the png i am trying to import is exactly 1*1 units big?

buoyant knot
#

Does acceleration in unity just work like velocityNext = velocityOld + acceleration * Time.deltaTime?

swift crag
#

that would be valid, yes

#

acceleration is a change in velocity over time

#

like how velocity is a change in position over time

buoyant knot
#

i have to ask because classical physics only apply if you make it apply

#

I’m thinking about making a kind of different rigidbody API

#

let me know if this sounds dumb;

  1. Make singleton class with a list of all rigidbodies in scene that I need for calculations. This singleton class keeps a record of current position, previous position, defacto current velocity, desired MovePosition, and totalForce.
  2. Give rigidbodys extension methods that are used instead of MovePosition or AddForce, that only go tell that singleton to update values.
#

Script execution order:

  1. Singleton log: go through all rigidbodies and create new logs (velocity = old position - new position….), totalForce = 0….
  2. All my scripts do their thing, adding forces etc to singleton
  3. Right before physics calculation, singleton class (or some other helper class) goes in, and combines all the MovePositions etc to a covesive final result.
#

Good/bad? Pointless? Ideas?

swift crag
#

I don't see what the point is.

#

It sounds like you're just recreating AddForce

buoyant knot
#

So let’s say I have a player on a dynamic block that is on a kinematic platform moved by a kinematic motor moved by MovePosition.

swift crag
#

ah, you need to manage frames of reference

buoyant knot
#

exactly

#

so if multiple items down the line call MovePosition, it doesn’t work

#

because MovePosition commands overwrite each other, and only get executed in physics step

#

transform parenting doesn’t work… because idfk why

swift crag
#

because parenting something means its transform is getting messed with by something other than the physics system

buoyant knot
#

apparently having a dynamic rigidbody on a kinematic moving platform was not a common situation during unity development

buoyant knot
cosmic dagger
buoyant knot
#

even a joint. I would take a Joint tbh that moves an item, while letting it move freely

buoyant knot
#

so if the platform moves +2x, and the block moves with a force for +1x velocity, it can just get transferred to the player on the block on the platform

#

idk why this is so hard to do

valid finch
#

@rich adder so if I build a game that does local multiplayer.. would I need to do a complete overhaul of the code in order to make it online multiplayer. Because all of this netcode stuff is something I will need to learn to use, but I was just wondering if for testing purposes to get the base game working it would be ok local? Or is that going to be just way too much work to convert into online also in the future??

or anyone that has input on my question

It just feels like I don’t have tools that work to sync their movement.
-MovePosition requests overwrite each other.
-Moving transforms makes janky collision
-I can’t just add force to a target position
-Joint2D either don’t sync motion OR block the child itself from moving with its own scripts
-Parenting transforms just doesn’t work
-Physics scenes don’t seem scaleable for this
I’m just so frustrated

could start now looking into what you have to port over

but I was worried I would run into major issues if I didn't plan for it now.

#

Figured multiplayer is multiplayer, but I am naive

rich adder
#

make a separate project and play around with just network package

#

you won't know for sure until you dive into it

valid finch
#

Whatever the player 2 controller does seperate it from the player 1 controller

rich adder
#

aint even about the controls

#

its sync 2 or more sessions of the same game

valid finch
#

and then have the game manager and stuff be shared

rich adder
#

so if 4 people playe your game, your scene is running 4 times. at different rates, so sync info between that is the challange

valid finch

Sorry, i'm not a complete moron.. despite how I sound right now lol... I am just overwhelmed with the revelation that I can't really progress until I understand something I wasn't planning on learning until a ways down the road you know?

Multiplayer is all about maintaining consistency. You can no longer rely on everything happening in a specific order.

#

It's a lot to think about.

Im not saying you are, its something you have to try out before you know what you need to port over from your current project

But when the qb passes the ball (has a pass speed) and the receiver is running a route along the x and y axis. at a speed.. I need to calculate where a straight line would need to be drawn to make the ball and the receiver hit each other in stride.

its distance + velocity (time) something along those lines

you're basically solving a system of two equations

your choice of angle determines how quickly ∆x and ∆y change, and you want both to wind up being zero at the same time

You should reset buildTick to 0 when 20 is reached, right?

OR, check it like if(buildTick % 20 == 0)

Does the equation you send me account for the fact that different players can have different throwing velocities. I don't want the throw velocity to be based upon any factor other than what it is set at for the player's stat. If that makes sense. I am looking over the equation you sent and seeing what variables I have and what I need to create

buoyant knot
#

it is a function of whatever throw velocity you plug in

frail adder
#

is it better to use rb.velocity or rb.addForce for horizontal movement when creating a platformer?

buoyant knot
#

I would make a function: CalculateThrowVelVector(Vector3 receiverPosition, Vector3 throwerPosition, Vector3 receiverVelocity, float throwSpeed)

valid finch
#

Ok, thank you. I was looking at the final line you wrote

#

Was just trying to understand what that was for. Since the throw speed was already defined.

buoyant knot
#

Some of the other variables like angle, and (vector between thrower and receiver), and distance etc can be calculated from just those variables

#

you have throw speed. you need throw velocity, which has direction

valid finch
#

Ok, I wasn't sure, because I am not using actual physics in my game. This is just for the animation of the ball sprite to travel

buoyant knot
#

ie you know how fast the ball moves, but not where to throw it

valid finch
#

The ball won't be bouncing or dealin with gravity it is all done through animation

buoyant knot
#

yeah, this assumes none of that

#

this would be substantially more complex if you add gravity or anything to the mix

valid finch
#

Speed + direction is velocity. I forgot that speed and velocity weren't interchangable

buoyant knot
#

yeah. if you have that function, you can use it for any such case. plug in different throw speeds etc

#

that way you only code once

valid finch
#

Makes a lot more sense now. Thank you very much for your help.

buoyant knot
#

sure. also I think I used Vq and Vp interchangably for speed of QB and pass. They should both be speed of pass

This is a static rigidbody, so it's not moving. If the other object were dynamic and moving into it, it'd work

but a static rigidbody will not send collision messages

since it doesn't move

ooohh

it worked

dont procceed to add rigidbodies for all the pipes tho use only one on the bird itself kekW

buoyant knot
#

i have rigidbody 2d in dynamic mode, where I need to translate them, and apply normal dynamic physics after. So my idea is; Set them all to kinematic mode, MovePosition to where I need, Physics2D.Simulate(0) so they move while respecting collisions without screwing with time-dependent code, then set back to dynamic mode.

#

Q: Would this work?

#

oh but the kinematic RBs wouldn’t push other things that should be dynamic…

Oh apologies

#

While using the unity input manager system and the ”new input system” i have 4 different players with their own player input component so they are controlled by one gamepad each, whats the approach on making a UI system which is shared between them all?

wintry quarry
royal ledge
#

@wintry quarry In that scenario each player has their own ui system

wintry quarry
#

you'd have to explain what kind of ui system you want

royal ledge
#

Like a menu that everyone can control

wintry quarry
#

that's vague

#

there are many ways to make "a menu that everyone can control"

#

for example there's Super Smash Bros' characte selection screen

royal ledge
#

Sorry i will try to be more specific, imagine a player presses start: A pause menu appears, with options up to down. The first option is selected. If player 1 presses down the selected option becomes the second option, if player 2 then presses up the first option will be selected again. They all share the same menu, and the same ”pointer”

wintry quarry
#

In this case you can use a regular event system and just write a custom input module that accepts inputs from any of your players

#

should be relatively straightforward

royal ledge
#

Aye thanks, all i needed was a point in the right direction, appreciate it

buoyant knot
#

would anyone know how MovePosition works on dynamic RBs? Does it ignore the request? Or does it actually try to move

naive lion
#

Hey really beginner question here
Im making a blink (tp) mechanic
Should I do this seperate to the controller for modularity or integrate it into the movement

frosty hound
#

If you have no intention of using it modularly outside of the player, then just integrate it.

naive lion
#

Awesome
Wasnt sure if either way it is better practice to do it seperate

buoyant knot
#

I am almost always in favor of separating

#

you might realize it's pretty simple to reuse the behaviour, or your original script gets huge (and later becomes messy)

I'm having a really hard time trying to edit the values of an object that I instantiate because it keeps changing the value of the prefab instead. I try to set the prefab to a gameObject in start() but I can't access it in any of my other methods, can someone please explain how this system works?

untold bobcat
#

How do you get a component with the type of a specific interface?

#

This doesn't give me any errors, but it also just returns null:
spellType = GetComponent<ISpellType>();

summer stump
#

Now, the start method only runs when it is actually active in the scene, so that should not modify the prefab unless you explicitly tell it to

#

You may wanna show the code so we can understand what's going on better

You should log it.

what if the raycast is failing?

buoyant knot
#

ok, do you know how inheritance works?

#

and how a class can only inherit from ONE other class in C#?

untold bobcat
untold bobcat
buoyant knot
#

interfaces are like a way around that

#

do you know how abstract methods work?

#

where you are forced to override in a child class?

untold bobcat
buoyant knot
#

ok, an interface is like an abstract class, where every method is public abstract

#

AND then you are allowed to multiple inherit with them

untold bobcat
#

Yeah Im aware of all that

buoyant knot
#

most interfaces have like 1-4 methods tops

untold bobcat
#

Im not sure how I made tha tmistake lol

swift crag
#

see, if we only had typeclasses...

untold bobcat
swift crag
#

haskell typeclasses just require that you've defined a set of methods that work with a specific type. the type never explicitly "implements" a typeclass

buoyant knot
#

interfaces are really useful when you have multiple classes that are pretty different, that all need to expose a similar method that does something similar

#

Example; I have an ISpawner, which is an interface that any sort of spawner needs to have. Specifically, methods like SomethingWeSpawnedDied, SomethingWeSpawnedDespawned, and TrySpawnSomething.
And you can slap that interface onto a spawnpoint, or a pipe from mario, or bill blaster, or whatever. The spawner class can be all sorts of different things.

#

But now the thing it spawns doesn’t care. It just looks for an ISpawner to report it died/despawned/etc

#

idk if this helps, or you already know all this

sudden sand
# summer stump It is locally scoped. That's why

When i declare it in the class and run the code it still edits the prefab:
In a different class it tries to call the healthBarObj but it errors with "object reference not set to an instance of an object"

public void takeDamage(float damage)
{
healthAmount -= damage;
"healthbarobj"().fillAmount = 0.5f;

}

#

there are 4 separate objects just on the left hand side of the assignment operator that could potentially be null

sudden sand
#

Ok I'll spit it up and try and do some debugging

swift crag
#

a little suggestion: you should have a Healthbar component that holds a reference to the image

#

GameManager should also just be a reference to GameManagerScript, not a game object

#

then you could write GameManager.GetHealthBar(playerNum).image.fillAmount = 0.5f;

#

still a mouthful, but better

#

you could also then give Healthbar a method to set its fill

#

this would be nice if you want to make the healthbar slowly go up or down

#

or wanted to show a number along with the bar

#

or many many other things

# 
GameManager.GetHealthBar(playerNum).SetPercentage(0.5f);
#

this makes it very clear what the objective is

#

you're setting the healthbar's percentage to 50%

Hi. Working on a First Person Beat-em-up and I'm having trouble with the item grabbing system. I followed a tutorial. Everything works perfectly. The only problem is when I go to attatch the GameObject to my camera, (interact/pickup) It scales depending on my camera's rotation

swift crag
#

Sounds like non-uniform scaling.

slender nymph
#

don't attach it to the camera

#

but also that

teal vale
#

I wish I could send a video, but it bypasses the file size limit

slender nymph
#

you can use something like a parent constraint to make your holder object follow the camera as if it were a child without actually being a child

swift crag
#

If an object's parent has a non-uniform scale, and the object rotates, it will get skewed as it rotates.

teal vale
slender nymph
#

parent constraint . . .

teal vale
#

my script makes it so that when you interact within the collider range, it teleports the object to an empty

slender nymph
#

congrats. use a parent constraint so that "empty" gameobject acts like a child of the camera

sudden sand
# swift crag you're setting the healthbar's percentage to 50%

I'll try and do this, the problem I set for myself is that I have three characters that all have to have different health bars, I need to instantiate the healthbars to match the color of the character, but I need to set the parent of the healthbars to the canvas since they weren't working when I didn't... long story short, I need one code that can instantiate one canvas and three prefabs and it runs three seperate times because I have individual health managers for each of the plays... sorry if that doesn't make any sense, ive been working on this one code for a few days and its driving me a tad insane

swift crag
#

making a dedicated Healthbar class will also make your life easier

teal vale
#

also, I don't know what parent constraint is, so in order for me to be less of a nuisance to you, you might have to explain instead of expecting me to know everything

swift crag
#

the healthbar can even reference a health manager

sudden sand

and then update all by itself
