This?

languid spire
#

you are using build and run so the port number used is not fixed

hollow zenith
#

yes

#

But refreshing the page keeps the same port, so the game should load still?

languid spire
#

yes

hollow zenith
#

It doesnt

rich adder
#

add another line for PlayerPrefs and try

languid spire
#

ok, does your browser clear cache?

hollow zenith
#

no

languid spire
#

you still didn't answer what is 'Game Saved 0' ?

hollow zenith
#

Game Saved 0 is how much "gold" is saved

#

Because it didnt load in this case so it just keeps saving fresh state

languid spire
#

try loggging the length of the save string

hollow zenith
#

I can log the whole save string?

languid spire
#

also after save, read it back straight away

hollow zenith
#

Is it weird that build can take few minutes, but if I restart windows explorer the build takes 1 second?

#

build.js(wasm) is where I am stuck at building most of the time, but if I cancel it then restart windows explorer and try to build again it will be instant.

#

On Save:

/idbfs/0634cbebe13ad9e3d93ee318fd86dd00/Gold.json

languid spire
#

ok, so the file is saved

hollow zenith
#

Maybe it really is the cors issue

#

even tho it has something to do with Unity cloud

languid spire
#

which means your browser is clearing the cache

hollow zenith
#

I dont know how

#

It doesnt delete anything when firefox is closed

#

But I never had issues with online games not saving

languid spire
#

that is default behaviour for the browser unless you tell it different

hollow zenith
#

then this is the worst solution for save/load system 😄

#

There is no way I can force players to change their hidden browser settings just for my game.

languid spire
#

yes, that's why online games dont save to browser but to backend storage

hollow zenith
#

So how come playerprefs work?

languid spire
#

no idea, I dont use them

hollow zenith
#

So what do I use in order to have a working save/load system in webGL that also works on other platforms?

languid spire
#

you'll need a backend server

hollow zenith
#

I dont believe that...there has to be a way to save it locally.

languid spire
#

not in WebGL, you are not given access to the local file system

hollow zenith
#

There is localstorage, indexedDB, playerprefs(those actually work without backend server)

#

afaik playerprefs use indexedDB too

languid spire
#

but indexdb is what you are using now

hollow zenith
#

well thats the issue.

languid spire
#

if you are sure PlayerPrefs will work for you why not just save your json string to playerPrefs and have done with it?

hollow zenith
#

We might do that, there were some reasons against it but if nothing else works we will do it.

keen dew
#

I'm pretty sure it does save the file to IndexedDB. The contents are saved as an Int8Array to FILE_DATA.

hollow zenith
#

Nothing I tried allowed me to load the data
It fails at:

string filePath = Path.Combine(Application.persistentDataPath, "Gold.json");
if (File.Exists(filePath)) // Fail
keen dew
#

Do you restart the game with build & run in the editor?

#

persistentDataPath changes for every build

hollow zenith
#

I build + run then I refresh the page after playing for a bit + saving the data

#

but the path stays the same

keen dew
#

Don't build, just refresh

hollow zenith
#

Yes I only build 1 time

#

Could it be CORS issue?

keen dew
#

no

hollow zenith
#

Even loading simple string doesnt work, it just fails at "File.Exists"

#

Fails = nothing happens since it fails to go through if statement.

Hello, im trying to make a simple fps controller for a school project. I have these 2 scripts to control the lateral movement, it seems like it should be fine but the capsule is not responding to my imputs at all. I get no errors in the debugger, just no reaction from the object. Any idea what is going wrong there?

Level is a component in the prefab

then you may want to use GetComponentInChildren

faint lark
#

ok

languid spire
#

without the t:

faint lark
#

yeah

same thing

#

as before

#

doesnt get to Level component

#

the Level component is in the gameobject itself, not in a child

languid spire
#

show the inspector of one of the prefabs

faint lark
#

_lvl is null basicly

languid spire

that's not what I asked for

this?

the Inspector of the prefab. like LevelTitan

I cant see why that is not working, I would suggest getting all components from _obj and looping through them to see what comes back

how do i get XR inputs with pure code? (new unity input system)

ripe shard
# wooden minnow how do i get XR inputs with pure code? (new unity input system)

you have two options (examples):

Quaternion rightHandOrientationValue = default;
                
// Option A: action map created via code
InputActionMap xrmap = new InputActionMap ("My XR Input Map");
InputAction rightHandOrientation = xrmap.AddAction ( "Right Hand Orientation" );
rightHandOrientation.AddBinding ( "<XRController>{RightHand}/orientation" );
xrmap.Enable ();
rightHandOrientationValue = rightHandOrientation.ReadValue<Quaternion> ();

// Option B: Hard coded via Static API
rightHandOrientationValue = XRController.rightHand.deviceRotation.ReadValue ();

how would i get button inputs

#

In the 2nd video, the cards aren't rising at all, but when the pointer leaves the card, it still drops down. And there's also just weird behaviour going on.

wooden minnow
#

like what's the difference between AddAction and AddBinding

deep bear
#

Does anyone know what I could be doing wrong with my code? I've also tried using stuff like transform.localPosition = new Vector3(transform.localPosition.x, transform.localPosition.y + 20, transform.localPosition.z); instead of cardTransform.anchoredPosition = new Vector2(cardTransform.anchoredPosition.x, cardTransform.anchoredPosition.y + 20); but none of it works

ripe shard
# wooden minnow what does AddAction() do?

AddAction creates an action, i.e. an abstract input event you want to query, AddBinding defines how that action is triggered specifically (button presses, joystick movement etc.)

wooden minnow
#

im still confused

#

do you need an action for a binding?

ripe shard
#

they key to understanding InputSystem is to understand that it is designed to make input fully abstract and do away with the idea of a button press

#

so yes, you need a binding

#

you need to define what a given action is

#

if you use the static API (example B above) the common inputs you'd expect from a simpler input system (like the old one) are premade for you

wooden minnow
#

does the name of the action matter?

ripe shard
#

no

#

you can however search for actions by name (but you should avoid that, just for sanity's sake)

wooden minnow
# ripe shard no

is there any way to know if a binding does something? or what that binding outputs?

I wanted to make a timer with this code

private void Update()
{
    if(timerRunning)
    {
        timerMs += (int)(Time.deltaTime * 1000);
        UpdateTimerUI(timerMs);
    }
}```

but if I start the timer on a different pc then put a recording of my and the other pc ontop of each other so that they start at the exact same time, after 19 sec I have a difference of  about 1 sec is this normal? And if so how should I do it then?

keen dew
#

it should be

UpdateTimerUI((int)timerMs);
ripe shard
#

the "real" way to use InputSystem is through such an input action asset anyway

you use the code-api only if you want to make a convenient default config for prototyping or quickstart or if you wrap the whole thing into your own tooling for special needs of a complex project

actually, different question, I've got two types of items that can be displayed in an inventory slot, so I basically copied over the display inventory script and adapted it to fit this structure item slot, but this doesn't feel at all right. Is there a way to just have one class that can accept any type so they aren't both duplicated?

just a random triangle of some different color so that i can see which way its facing

#

without adding more objects, just the graphic

wintry quarry
#

I shared the easiest way I can think of

delicate pewter
#

The axes on gameobjects, do they turn with the object? So for instance the blue arrow (forward) does that rotate with the rotation of the object?

In Scene view

Or is it locked as some sort of global axis

How can I shift the transform.forward vector a certain amount of x to the right or left?

hidden sleet
#

Can't believe I didn't spot the brackets though

wintry quarry
wintry quarry
hidden sleet
#

i've not used too many methods that need the <> so I guess I assumed that replaced the brackets

delicate pewter
#

But I also want to shoot one abit to the left and a bit to the right

wintry quarry
#

right and I'm asking you to clarify what you mean

#

when we're talking about a direction vector generally you mean you want to rotate that vector

delicate pewter
#

Not looking to rotate anything, i just want to shoot a raycast to the left and right of the forward vector

wintry quarry
#

shifting it to the right or left might mean moving the position, not changing the direction

delicate pewter
#

I want the forward to stay as it is. Just want to based on the forward, shoot to the left and right of it

wintry quarry
#

blue to magenta is a rotation of the direction

#

green to red is moving the origin of the ray

delicate pewter
#

Yes blue to magenta

wintry quarry
#

so yes you want a rotation

delicate pewter
#

but i dont want the gameobjects actual forward vector to rotate

#

But yes i do want an "imaginary" one to rotate that i can use

wintry quarry
#

phone call

#

royal ledge
#

Lool, i was 100% sure he meant green to red

gaunt ice

you can rotate the copy of forward vector

delicate pewter

Yeah i figured that was the case with praetors reply

#

makes sense

#

Ill try it

#

Yeah worked, ty peeps

#

With raycast hits, I need to check after each raycast right, I cant cast 3 raycasts and then do stuff based on the hits?

#

Since it doesnt differentiate the hits ? probably just writes over them?

use 3 different variable to store the raycasthit result

Yeah was just about to write that, but i have to store between each cast that is

Hello! How to make it visible?

That square which is an image

#

(Im using a Scroll Rect component)

delicate pewter
#

Physics.Raycast lets you ignore certain layers, is there a way to do the opposite, make it only HIT certain layers?

#

Or rather, just one layer i need it to hit

wintry quarry
wintry quarry
#

actually the normal behavior is to only HIT the layers in the mask

delicate pewter
#

A little vague wording i guess but sounds to me like its specifying which i want it to ignore

#

I mean I guess I can just let it hit everything and then check whether the object hit is in a certain layer

#

Tho it will mean that the ray is cut short in the event of ignored layers but whatever maybe its fine

#

Ah nvm i understand it now, my bad. Been a while since using Unity, a layermask is a layermask, not just one layer lol

#

Is there a difference between using a parent game object for movement logic and a childed capsule for collision and just simply using a capsule for it all?

#

I've seen some tutorials do systems differently and I just wanted to know if I should bother look into it

wintry quarry
cunning rapids
wintry quarry
cunning rapids
#

I meant that a single game object has both collisions and rigidbody movement

wintry quarry
#

There are many advantages to having the collider on a child object.

  • It can be animated separately from the parent
  • It can have custom scripts on it that for example have collision callbacks that apply ONLY to that collider (and not other colliders on the body)
  • It can have a different layer and/or tag than its parent
  • It can be scaled/rotated/positioned relative to the parent
cunning rapids
#

Understood

#

But I'm having trouble with using the collider as a child

#

Because I created this simple script for teleportation

#

For some reason it messes up with crouching and collisions

wintry quarry
#

you'd have to share details of the script and the trouble you're having

cunning rapids
# 
using UnityEngine;

public class Teleporter : MonoBehaviour
{
    public Transform destination;
    public GameObject objectToTeleport;

    private void OnTriggerEnter(Collider other)
    {
        if (other.gameObject == objectToTeleport)
        {
            TeleportObject(objectToTeleport);
        }
    }

    private void TeleportObject(GameObject objectToTeleport)
    {
        if (destination != null)
        {
            objectToTeleport.transform.position = destination.position;
        }
    }
}
#

But since the parent game object doesn't have a collider, I decided to teleport the child

#

But it messes up the position of the parent I'm guessing

wintry quarry
#

if you want the parent you can just do other.tranform.parent.gameObject

#

Or perhaps the safest thing assuming these are all root objects in the scene is other.transform.root.gameObject

#

Though I'd probably just use Transform directly instead of needlessly involving the GameObject, since you're only just accessing the Transform again

cunning rapids
#

Makes sense

I wanted to have it so that clicking one spawns an item in the scene, which is what I was resolving earlier, but removing it from the UI isn't working as expected.
Currently got another issue when trying to remove a UI element from the screen. In this case I have a dictionary that uses an inventorySlot to point to a GameObject, the slot in the Ui that displays that item, which is assigned here as expected.

In the code screenshot, I can see that when the next scene loads it is correctly assigned as a pair in the dictionary

image.png image.png
#

But then when I click on '2' and watch the execution, the value suddenly becomes null, and get this error

image.png image.png
#

But I'm not sure why it just becomes null when the dictionary had the gameobject stored properly when the scene first loads

wintry quarry
#

"The object of type GameObject has been destroyed"

#

Which is exactly what happens to all GameObjects in a scene when the scene is unloaded

#

You still have a stale reference to a GameObject in the previous scene

#

Unity overrides the ToString() on destroyed objects to say "null", it's not actually null

hidden sleet
#

in this case the scene isn't unloaded, from what I see here in the first screenshot it adds it to the dictionary when the scene loads

image.png
#

so i would have thought the gameobject it references is the one currently existing

wintry quarry
#

You are somewhere destroying the object, either by unloading the scene or manually calling Destroy on it

hidden sleet
#

I'm not calling destroy anywhere else bar the method shown a few messages above, but can't destroy it cause there isn't a gameobject in the value.

I've got no clue why else the objects would be unloading though

wintry quarry
#

or use the debugger

wintry quarry
hidden sleet
#

just this one

image.png
wintry quarry
#

it's bugging me btw that you write this whole thing itemsDisplayed[Inventory.InvContainer[i]] instead of just obj which is the same object in that earlier screenshot lol

wintry quarry
hidden sleet
#

but it's not actually destroying anything since there's nothing to destroy

#

since the dictionary value inside is always null for me

wintry quarry
#

maybe you're looking at a completely different dictionary

#

a different inventory reference, different co[py of the script, etc.

#

hard to tell from these limited screenshots

hidden sleet
#

hang on, think I may have an idea

distant robin
#

hi can someone help me please?

wintry quarry
#

upload as mp4 to get embedded in discord

hidden sleet
#

so in this case, my inventorySlot consists of a custom Item object alongside a count. At the start I add an item to the dictionary with that slot as the key and the object as the gameobject. i reduce the count by 1 in a script outside of this one, then I want displayInventory to change to reflect that. But if I reduce the count by 1, then use that as a key, will the fact that the count isn't the same mean that It can't find the gameobject and returns null?

Hey this code makes no sense but I'm curious. How do you access different components of same type on an object?
I assumed GetComponent would return an array but it does not apparently.

image.png
wintry quarry
#

the singular version only returns the first one

#

you can also do:

[SerializeField]
Collider myCollider;``` and drag a specific collider into the slot in the inspector
#

Often if you have multiple colliders, putting them on child GameObjects can be best practice though

distant robin
wintry quarry
#

or about 66 milliseconds total, which is very fast

As for looping, can you show the inspector for the animation clip

had a look through all my other classes and set up some debug log messages, but I still can't find why it's setting it to null. Is it possible that the key has changed so it can't find the object rather than the object not existing?

buoyant knot
#

i would make a custom property for this

#

use a custom setter, that gives a Debug.Log every time it is called

wintry quarry
buoyant knot
#

IndexOutOfRange/KeyNotFound mean the array/list/dict are not null, but the entry is not in there

#

NullReferenceException => list/array/dict is null

hidden sleet
#

what if the dictionary key is the slot but a custom int count inside is different to what I pass in? Here for instance the actual count for the item slot will be 1, but the itemsDisplayed dictionary will still have 2 since it's been reduced by 1

image.png
wintry quarry
#

I don't really know what "count" is referring to here

hidden sleet
#

the number of items in an inventory slot

buoyant knot
#

i think you want TryGetValue

wintry quarry
#

what does the number of items in the slot have to do with this though

#

what is itemsDisplayed exactly? A map of what to what?

#

Some internal inventory object to a UI GameObject?

hidden sleet
wintry quarry
#

is the key a struct?

#

If it's just a reference to a reference-typed object, the data inside doesn't matter

#

in fact the data will always be the same everywhere you look at it because you're referencing the same object

#

if it's a struct, then yes you have issues here

hidden sleet
wintry quarry
#

But I think it's pretty clear form your earlier screenshot that there exists an actual mapping int he Dictionary to something that is showing as null

wintry quarry
#

the only thing that matters is the actual reference.

hidden sleet
#

so the count being different doesn't matter, gotcha

wintry quarry
#

as long as you're referring to the same object

hidden sleet
#

i see

wintry quarry
#

it will have the same count, because they're the same object

#

that's how reference types work

#

your variable stores basically a pointer to the object, not the object itself.

buoyant knot
#

i assume the dictionary maps Item key to int value?

#

i’m very confused by your code tbh

hidden sleet
#

cause essentially all I wanted to do here was have it so that I can use the inventory slot as the key and change the details of the game object that way

image.png
wintry quarry
#

so Item is.. .a GameObject?

wintry quarry
buoyant knot
#

we’d need to know the types at play here to do anything

hidden sleet
#

and for adding to the count in the slot it works, as the previous scene. These ui elements would be the gameobject in the dictionary, and the inventoryItemSlot is the actual item in the inventory

image.png image.png
wintry quarry
#

what type is the dictionary 😵‍💫

hidden sleet
#

did I not post it above?

buoyant knot
#

no

hidden sleet
# 
public Dictionary<InventoryItemSlot, GameObject> itemsDisplayed = new Dictionary<InventoryItemSlot, GameObject>();``` in case the image isn't loading
#

So when this second scene loads, it should look at all the items in the inventory and create UI elements for them, adding them to the dictionary. Then when the Ui element is clicked it will remove it from the inventory, and then perform this method to change the UI number or destroy it outright depending on how it changes in the inventory. but here is where the gameobject ends up as null

#

layer mask should mask a layer when a doing a raycast, right?

wintry quarry
#

only the layers in the mask will be included

gaunt ice
#

it is some sort of filter

desert elm
#

oh- thats
a bit confusing, right, thats why its not working

wintry quarry
buoyant knot
#

LayerMask is a bit mask. 32 ones and zeros, where 0 at position X means to ignore layer X.
Layer is the index (X) in that layer mask.

wintry quarry
buoyant knot
#

so 0011 means include 1/2 and exclude 3/4

hidden sleet
#

what do you mean by drill down?

wintry quarry
hidden sleet
#

oh I see what you mean

#

it's been taking longer and longer to load up which is strange

#

right then, so upon loading up the scene it's picked it all up properly. oh, and it's all just gone when I run the update

image.png image.png
#

the gameobjects still exist in the scene which is the most confusing part for me

wintry quarry
#

BTW this definitely means it's a destroyed object

image.png
#

and not real null

hidden sleet
#

got this one that handles clicking the UI, this one for actually removing the item, then it fires the event that runs the display update one

image.png image.png image.png
desert elm
#

and is layer zero included?

gaunt ice
#

2=0b10
3=0b11

buoyant knot
#

i think it’s offset to be 0-31 actually

#

so 0011 would be 0/1 on and 2/3 off

#

i think

stiff birch
#

isn't layer 0 = none ?

desert elm
buoyant knot
#

0b means representing a number in binary

#

0b01 means the number corresponding to 0000000000000…0001 in binary

gaunt ice
#

binary format, fyi 0x = hexadecimal

wintry quarry
desert elm
#

oh right thanks

buoyant knot
#

you can also add/subtract layer masks, fyi

#

0010 + 0100 = 0110

#

there are good extensions to just automatically make consts for individual layers and layer masks

#

that's underselling it

#

Probably not a bool

#

maybe more like a list of item names or ids

hidden sleet
#

Looks like it did on my end, there were 2 cardboard items before the remove method is called

image.png image.png
wintry quarry
#

like itemsOwned: ["dagger", "cat", "lamp"] in some list somewhere proably belonging to a broader "game state" object

sterile radish
#

oh okay

#

and i would append the bought item to the list you mentioned whenever the player buys it correct?

wintry quarry
#

yep

sterile radish
#

alright thanks!

hidden sleet
#

I just think it's odd how adding items to it works in every other scene, it's just removing that isn't working

wintry quarry
#

tbh I don't understand why this is happening in Update anyway? Why not immediately remove the things when you remove the item

#

THough I'm a bit unclear if this is running in Update or not

#

Actually now that I'm thinking about it, isn't it clear this code is the very thing destroying the object? Then you're looking next frame and you see a destroyed object there, naturally

image.png
#

You never actually remove it from the dictionary, right?

#

don't you also want itemsDisplayed.Remove(inventory.InvContainer[i]);?

hidden sleet
#

nothing runs from the Update method specifically, I just use an event when the item is removed from the inventory

wintry quarry
#

wait also if that thing is null, aren't you just destroying nothing? Why would there be a null key in the dictioanry in the first place? That's really odd

#

this is just... weird overall the more I think about it

hidden sleet
#

If I run it through from the start I can see that before removing there are two cardboard items, which are then removed in the script that handles someone clicking the UI slot. Then since the inventory has been changed, it goes to update the display. and i can see that the container has the current slots and totals. The dictionary is pointing to the right key but then of course it's just null. And it's never ran the destroy method, these lines are the only two it runs through

image.png image.png image.png image.png
#

I suppose the only other way I could try it is if destroy the object this script belongs to after removing the item from the inventory?

#

Is that possible?

#

might put a pin in this one. Spent 5 hours already trying to resolve it but i just can't seem to amend it

#

I can see now why people say to start off with smaller projects, if I tried doing a large one now I'd be so burdened by my awful script structure that I'd never be able to make anything work on a large scale

sterile radish
#

yeah

sterile radish
#

you would need some kind of saved game system to persist between play sessions

If you put the script of the method in fixed update, then it won't work. It's not bad. Everyone learns from his mistakes. Fixedupdate is a method on it's own, so you're putting a method in a method now.

you could better do smt like:

... fixedUpdate() {

#

So each object will have its own data.

#

A static member doesn't live on an instance

#

There is always exactly one copy of it, and you access it with the type name, rather than accessing it from a specific instance

swift crag
#

so, when a GameManager wakes up, it writes itself into that static gameManager field

#

If no GameManager has woken up yet, GameManager.gameManager will be null. Otherwise, you'll get the most recent GameManager to have woken up.

hidden sleet
#

gotcha

swift crag
#

This is a pretty common pattern for "manager" types. It's usually called the singleton pattern.

hidden sleet
#

I've used static variables a fair bit in the past but the way unity deals with stuff just has me confused at times

wintry quarry
hidden sleet
#

but I could use that approach for my inventories perhaps

swift crag
#

The main thing to keep in mind is what happens if a Unity object is destroyed

#

If the object stored in gameManager is destroyed (e.g. by a scene unload), the variable will return true if you check if it equals null

#

(because all unity objects do that)

# 
if (GameManager.gameManager == null) {
  Debug.Log("No game manager has woken up OR the latest game manager has been destroyed");
}

Also, hi blushie

static fields live for as long as the program does, so the value will only change if you write a new one

What version of Unity should I install?

oh okay i think i understand now. BuyItem is no good since although it exists in multiple places, it is just a single thing. with GameManager, it acts as a centralized hub for storing data. what i said about restarting the game doesnt matter as everything in memory goes away once i stop the game. the only thing that remains are files or playerprefs correct?

#

okay, thank you praetor! 🙏

You need a way to turn the game's state (which items you've bought) into data you can store

and then a way to turn that data back into game state

Yeah, sorry. Meant left clicking

The first 2 if's affect Y axis, the third affects X

so not sure why it wouldn't work

swift crag
#

Check that your code is actually running with a Debug.Log statement.

#

Then make sure nothing else is setting the velocity of the rigidbody

#

oh, one other thing

#

Check the inspector to make sure GunKickBack isn't zero

#

If you didn't have = 500f when you first wrote the script, and only added that later, the inspector would keep the zero

west sonnet
#

Debug.Log works, and I also tried putting GunKickBack on the Y part, and it shot me upwards like it should

But for some reason, on X, it doesn't do anything

make bool for the .velocity part

swift crag

One: Don't set the velocity directly. Just apply forces to move the player.
Two: Store recoil velocity separately. Add it on top of the movement velocity.

The latter will be easier to control, at the expense of physical accuracy.

# swift crag How do you move the player?

In FixedUpdate() method, but I don't think that the result was different when I used Update().
I get input like this (with Player Input component):

private void OnMove(InputValue inputValue)

    moveInput = inputValue.Get<Vector2>();
}

My movement method is a bit messy, so it might be, that the values are going up and down, so rounding them or something may solve the issue:

private void HandleMovement()

    if (moveInput != Vector2.zero)
    {
        if (moveState == MoveState.Standing)
        {

        if (positionState == PositionState.InAir)
        {

You're not adding a ton of force, though

you're pushing with 50 newtons of force for 0.02 seconds

this is equivalent to using ForceMode.Impulse with transform.up for the first argument

Right

#

I believe u dont need to get the Cameras transform

U should be getting the forward of the player controller transform

So ur camera rotates the player correct?

Collider2D[] hitEnemies = Physics2D.OverlapCircleAll(AttackTarget.position, AttackRange, enemyLayer);

    if (enemyHealth != null)

how do i make sure thats not hitting itself

Oh thats....strange

Yeah i know, this seems to be the only method i can find without completely redoing my First Person Controller, which causes more issues..

whats wrong with this? its supposed to fill the tilemap from (1,1) to (5,5) but all it does is crash

#

I would say just use a character controller

#

Jittering in my experience comes from setting a camera on a rigidbody

#

Your also doing work arounds for what should be a simple system

#

@plucky vapor show the whole code

plucky vapor
queen adder
#

SI

twin bolt
#

Yeah i used a character controller, which worked, but removed my ability to interact with rigidbody objects.

queen adder
#

Wdym^

#

Like collisions?

plucky vapor
twin bolt
#

Yea, there were objects that had rigidbodys, and if i walked into them, they wouldnt budge.

queen adder
#

CharacterControllers have a collider? There shouldnt be a reason that didnt work?

#

Again abdullah

#

Why does ur NPC have a character controller

Usually you'd have some specific data that you would want to be saving from each scene, if any.

west sonnet
rich adder
#

maybe use a bool

plucky vapor
west sonnet
#

I will try that

swift crag
west sonnet
#

I'm not sure where to add it tho

queen adder
#

U set it in the inspector....

opaque kettle
swift crag
#

That will prevent you from changing your horizontal velocity until the coroutine is done and sends recoil back to false

rich adder
swift crag
#

Another option is to just move your velocity towards what the player wants, instead of instantly setting it

# 
rb.velocity = Vector2.MoveTowards(rb.velocity, new Vector2(Horizontal * speed, rb.velocity.y), Time.deltaTime * acceleration);
#

MoveTowards moves from the first vector to the second vector

#

but only goes as far as the third argument

queen adder
#

Thats pretty sick ^^

#

Im about to steal that

swift crag
#

You could also reduce acceleration right after shooting

#

so you have a brief moment of low control

plucky vapor
west sonnet
#

Essentially, I want to make a force that will push the player backwards from whereever their gun is facing to simulate recoil

swift crag
swift crag
plucky vapor
#

@summer stump@queen adderYESSS IT WORKS NOW!! Thank you guys a LOT for the help with this!

swift crag
#

you would also add a bool field called recoil

#

The coroutine would look like this

queen adder
#

@misty obsidian you only have one animation

#

So the Animation player plays that one animation

swift crag
# 
IEnumerator Shoot() {
  recoil = true;
  yield return new WaitForSeconds(0.5f);
  recoil = false;
}
#

something like that

#

Have you ever used coroutines before? I don't know if I'm using words you don't know about here :p

west sonnet
swift crag
#

It runs until it hits a yield, then it pauses and returns an enumerator

#

StartCoroutine tells Unity that you want it to check on this enumerator every frame (by default)

#

So every frame, it asks the enumerator to please continue

west sonnet
#

What's an enumerator?

swift crag
swift crag
queen adder
#

Haha

swift crag
#

Have you ever used foreach? If so, you've used enumerators.

#

Just with some nice pretty syntax on top.

west sonnet
#

Oh yeah

queen adder
#

you could alternatively just do Invoke("Method Name")

west sonnet
#

I've used invoke before

swift crag
queen adder
#

Invoke("Method Name" , 0.5f)

swift crag
#

Ah, I see what you mean

queen adder
#

If ur just doing a timer Invoke is fine

swift crag
#

You could achieve the same goal, yeah

queen adder
#

Just so its simpler to understand for D&M

swift crag
queen adder
#

Coroutines are confusing to learn at first

swift crag
#

When Unity gets a WaitForSeconds, it waits for however long you say before asking for another value.

I'm not sure what I'm meant to put here now. I tried putting AddForce but it didn't work

Can someone help me understand the fundementals of a saving/loading system, in my game i have lots of prefabs that get spawned, and each have different variables and positions that would need to get saved, how would i be able to even start to go about such a thing.

Welcome to one the worst parts of Game Development Save systems @sterile radish

swift crag
#

Serialization can be a real bugbear

west sonnet
sterile radish
queen adder
#

Theres a bunch @sterile radish but they each have there own benefits and disadvantages

swift crag
sterile radish
west sonnet
queen adder
#

That sounds fine?

sterile radish
#

really?

#

oh

west sonnet
#

This is what I've got now. It's not working 😦

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa.PNG
swift crag
#

I’ll be back in a few minutes. Fighting Comcast right now

queen adder
#

I dont know how list get serialized actually?

sterile radish
# queen adder That sounds fine?

i think i might be doing something wrong tho cuz it works when im running the game but when i close it and open it again it goes back to its unsaved state

queen adder
#

You should check if the recoil bool is true before starting the Coroutine @west sonnet

#

Do u have an actual save system?

#

If not then ofc the scene is going back to its default state

sterile radish
#

yeah i do

#

should i share it?

queen adder
#

Ofc

swift crag
#

yaaay, working internet

queen adder
#

Nice welcome back

swift crag
#

then it'll immediately return by recoil is true

#

so that's definitely not it!

queen adder
#

I shouldve explained it more detail ^^^ but yeah

swift crag
#

You should move if (recoil) return to the FixedUpdate line. That will prevent your velocity from being set while recoil is true

west sonnet
#

I defined the recoil bool to be false. Then when left click, it starts to coroutine which turns the bool true

swift crag
#

So the coroutine sets recoil to true, waits half a second, and sets recoil to false

west sonnet
#

Right?

swift crag
#

hence, no force

queen adder
#

Ur setting it to true then saying if it is true then dont addforce

west sonnet
#

Wait, where should " rb.AddForce(transform.right * GunKickBack, ForceMode2D.Impulse); " be?

queen adder
#

Its the if statement that should move

#

Put it above the StartCoroutine()

swift crag
#

I think it's in a reasonable place right now.

#

You want to apply the force when the player clicks the left mouse button.

west sonnet
#

So I put it inside where I check the left mouse is being clicked?

#

Oh right, yeah

is there code to clear all text from a json file?

And what does the second line do?

queen adder
#

On line 29 roshi you dont set anything to what playerprefs returns

west sonnet
swift crag
#

If recoil is false, the second line does nothing. The function then exits, since we've reached the end anyways.

#

The second line does nothing.

west sonnet
swift crag
#

You sound confused about what code is running when.

west sonnet
#

I am lol

rich adder
sterile radish
queen adder
#

Personally i would use a dictionary

#

Just for simplicity sake

#

Dictionary<Item, bool>

#

Just request the item from the dictionary and check the bool to see if its been bought or not

#

You can set the bool in playerprefs by using ints because for some shortsighted reason it isnt in playerprefs

sterile radish
#

oh okay and would this replace the boughtitems list in my itemmanager script?

queen adder
#

I know i threw alot at u and im sorry for that

sterile radish
queen adder
#

Yeah

#

Are u familair with the Dictionary class?

sterile radish
#

no but i could try

Save systems are complicated

You could just try ur original method of getting and settings strings

the layermask consists of 2 layers player and enemy

Check the Gameobject instead of the collider

if (enemy.gameobject != this.gameobject)

in risk of rain 2 when i changed the binding of a couple things the name went to ???

how do i get the input like that where it displays the name of the controller button i pressed

thanks

This works for Keyboards apparently if u have controller support youre gonna have to do some more research sorry lol

That only happens when ur next to and edge?

it only does it though if it hits the other person

im gonna try adding unity as a non steam game to see if steam will put the input on it

@queen adder Or use Physics.CheckSphere or some other physics query to check if you are grounded instead

Share the entire class

context.control.displayName for example

You can also ask for the display string for an input binding

Are any of the attack methods you have called ?

yeah

Is the player actually taking damage or is the animation just playing

they take damage

queen adder

Does the enemy get hurt?

amber spruce
#

i print it as a debug 1 i have a health bar go down aswell

amber spruce
queen adder
#

This just gets more confusing

#

Add a debug.log in the foreach

#

Does any other Gameobject have the ability to attack?

amber spruce
queen adder
#

Put a debug.log in the foreach loop

amber spruce
#

what should it log

queen adder
#

The gameobjects name

amber spruce
#

before or after the if

queen adder
#

Just in the Attack method

#

It doesnt matter where

amber spruce
queen adder
#

U printed the name of the gameobjects

#

@amber spruce

amber spruce
#

yeah

queen adder
#

That means the enemy is calling the Attack Method as well

#

I keep getting serialise and deserialise confused, which one is which?

swift crag
#

serialize -> turn your objects into data
deserialize -> turn your data into objects

#

serialize to save, deserialize to load

queen adder
#

@amber spruce any luck?

swift crag
#

To "serialize" is to turn something into a series of bytes

Was it what i said or was it something else?

What's the correct way to access a component existing on another object? Because this doesn't work 😅
