#

you changed the wrong = to +=. Please think a little about what you are doing

reef totem
#

u told me to

languid spire
#

I told you to change = to +=. I expected you to be sensible enough to know which one

reef totem
#

ok

#

one last question

#

how to i know how many units my cube will move foward

languid spire
#

well according to your code it is test*Time.deltaTime so that will be 2 units / fps

reef totem
#

since the variable test only controls the speed of the cube im geussing

reef totem
reef totem

languid spire
#

probably not as I don't know what you are trying to achieve

reef totem
#

thats litteraly it

summer stump
#

There is more to it than that

languid spire
#

ok, but over what time scale?. You have not thought this through

polar acorn
summer stump
#

How it transitions between those states is a huge part of it

reef totem
summer stump
#

They want to know how fast you want it to move

reef totem
#

like idc

languid spire
summer stump
#

But just try dotween as linked above

reef totem
#

maybe like 0.5 units per second..

reef totem
polar acorn
# reef totem like idc 
transform.Translate(5 * Vector3.forward);
transform.Translate(-5 * Vector3.forward);

There it's now moved 5 units forward then backward

summer stump
reef totem
zenith cypress
#

"why is it not moving" Kappa

reef totem
#

huh

reef totem
#

but i mean it makes sense

polar acorn
reef totem
#

both these command are being run at the same time so ofc its not gonna move

polar acorn
#

Since the time doesn't matter, this does solve your problem

reef totem
polar acorn
#

unless, of course, time does matter and you need to decide on what you actually want to be happening

summer stump
reef totem
reef totem
#

this is the speed

summer stump
polar acorn
#

Keep track of how much you're moving each frame, check if it's equal or greater than 5, then reverse it

summer stump
#

Ah yes, my initial suggestion 😂

reef totem
#

but then im changing it based on how much time it takes and not on how many unit it takes

#

if that makes sense

summer stump
#

You are changing by the units distance with digi's suggestion

#

It will not be affected by time at all

reef totem
#

can u give me some code to copy and paste so i dont look like an idiot

#

and accidently type the wrong thing

polar acorn
reef totem
# 
    public float units= 5f;
    void Update () 
    {
       transform.Translate(units*Vector3.forward * Time.deltaTime);
       
       transform.Translate(-units*Vector3.forward * Time.deltaTime);
    }
#

so i change units from 5 to 0.5

#

thats what your suggesting

#

i dony understand

summer stump
#

Not even a little

polar acorn
reef totem
#

yes i know

#

thats why im sooo confused

summer stump
#

One Translate call total

reef totem
polar acorn
#

So, how about you work through the suggestions, try to come up with a full solution, then post that, instead of trying to get confirmation for every intermediate step

reef totem
#

ok fine

#

but im trying to confrim every immediate step because if i dont i will just be judge and feel like shit

summer stump
polar acorn
#

I'll give you the necessary information in the form of a bulleted list:

  • You can translate an object by "X units per second" by multiplying X by Time.deltaTime as you pass it into Translate
  • If you store that value in a variable, you can add that to a running total to know how much you've moved an object by
  • If you check that running total, you can know if you've moved an object 5 units
  • If you multiply the speed by -1, you can start moving the same speed in the opposite direction
reef totem
#

also im been trying this for like the past hour and ive watched tutorials so its not like i didnt try

reef totem
reef totem
polar acorn
summer stump

languid spire
reef totem
#

im new to this

rich bluff
#

lets not doubt the effort put in, and instead be patient and try to explain

reef totem
#

this is all confusing

rich bluff
#

narrow down the source of confusion

reef totem
polar acorn
languid spire
# reef totem im new to this

which is why you should be thinking about every single little thing you do and work out in your head what that actually does

polar acorn
#

but it's not complicated enough to need one

rich bluff
#

coroutines serve a specific purpose - they give you asynchronicity

#

they allow you to pause and continue execution later

#

if the task you are trying to solve can be fully done in update, every frame, then coroutines are not necessary

reef totem
polar acorn
languid spire
reef totem
rich bluff
#

at least in my experience, the topic can get voodoo

languid spire
reef totem
#

i swear i do no undertsnad the bullet points for the life of me

#

ive been reading them over and over gaain

#

i didnt undertsna dexaplanaition

polar acorn
reef totem
#

so far i have 2 variables

# 
    public float unitSpeed = 5f;
    public float totalUnits;
rich bluff
#

you want to know how far the object travelled?

reef totem
#

yes

rich bluff
#

how do you know how much the object has travelled in one frame?

reef totem
#

I dont

rich bluff
#

how does your object know how far it has to go in one frame?

reef totem
#

unfortunatly

reef totem
rich bluff
#

but it does move?

#

using Translate

reef totem
#

yes

rich bluff
#

so somehow you already have that distance

#

otherwise the object wouldnt move

reef totem
# 
   public float unitSpeed = 5f;
    public float totalUnits;
    void Update () 
    {
       transform.Translate(Vector3.forward * unitSpeed* Time.deltaTime);
    }
#

this is all i have

rich bluff
#

what Translate does?

reef totem
#

move an object

rich bluff
#

how does it know how far to move?

polar acorn
rich bluff
#

it should click soon

reef totem
#

would x in this case be unit speed

#

im sorry

#

im just soo confused

rich bluff
#

you have transform.Translate( distance/direction )

#

your Vector3.forward is a vector3 (0,0,1)

#

one unit on z

reef totem
#

correct

rich bluff
#

which you multiply by 5, then by some time.delta value like 0.01

#

which will be the final distance and direction the object will move

#

(0, 0, 0.05)

polar acorn
rich bluff
#

so you can express your code like

# 
Vector3 distance = Vector3.forward * unitSpeed* Time.deltaTime;
transform.Translate(distance);
#

technically its not distance, i call it offset, since its a vector, not a scalar

#

but you can get the scalar with distance.magnitude

reef totem
#

so this is bassicly the same code by rephrased differenly

#

and then i times distance by something

rich bluff
#

remember the bullet point

reef totem
#

by speed

#

no

rich bluff
#
  • If you store that value in a variable, you can add that to a running total to know how much you've moved an object by
summer stump
reef totem
summer stump
#

distanceMoved += distance....
if distanceMoved > threshold

reef totem
#

i kinda undstand now bc i sort of have this with my player script

# 
 Vector3 move = transform.right * playerX + transform.forward * PlayerZ;

        characterController.Move(move * speed * Time.deltaTime);
summer stump
reef totem
#

ik

summer stump
#

Ok just making sure

reef totem
#

but im saying that this is sort of similar

rich bluff
#

i always prefer to create local variables that express intent

#

cramming everything into parameters or conditionals makes it hard to understand code at a glance

summer stump
#

That is a good practice for sure.

#

I do that with bools too, then my if statements are very short and clear

rich adder
#

always put V3 last in the calcualation

#

floats first (slight efficiency microptimization)

reef totem
# 
    public float unitSpeed = 5f;
    void Update () 
    {
        Vector3 distance = Vector3.forward * unitSpeed* Time.deltaTime;
       transform.Translate(distance * Time.deltaTime);
    }

so this is bullet point 1 complete

rich bluff
#

incorrect

reef totem
#

fuck

polar acorn
#

Actually, correct

rich bluff
#

you have double delta multiplication

queen adder
#

hey

polar acorn
#

Oh, wait

#

right

#

I didn't notice that

reef totem
polar acorn
#

it is, indeed, incorrect

reef totem
#

ok

#

no i deleetd delta time number 2

rich bluff
#

in this case yes

reef totem
#

so now bullet point 1 is complete

#

moving on to bullet point 2

He suggested me some operations, I did them all, but this time the jump animation does not work at all.

rich adder

use your brain

reef totem
#

whats a running total

#

u need that bullet pint number 2

I wonder if the problem is because I did not set the** gameObject** text as groundCheck?

reef totem

@rich bluff

polar acorn

#

to what

fervent mulch

#

A "running total" is just a variable that you keep adding to

reef totem
#

give an example

rich adder

fair enough

# fervent mulch how can i fix

you're better off following a proper structured course instead of a spambot
there is literally no condition here to tell it where its not grounded

polar acorn
summer stump
#

I don't understand what part is unclear

#

You make a variable called distanceMoved

reef totem
summer stump
#

You add distance to it

reef totem
summer stump
polar acorn

#

thats more clear

summer stump
#

And it was pseudocode at that, which basically is plain english

rich bluff
# 
Vector3 one = Vector3.one;
Vector3 two = one + one;
Vector3 three = two;
three += one;

What people here suggest will make no sense if you do not even know what you're trying to understand.

willow scroll

rich adder
#

Yes because blindly following the GPT wont get you to learn anything..

#

if you want to truly learn, then start with courses on the basics. Get a box to move etc..

fervent mulch

#

I was following gpt as well then It got so complicated I had to reset my brain and start from scratch.

maybe that works for you as well

# fervent mulch no

So questioning you "why is the line ... doing ..." won't give any proper answer, as you have non idea what a single character in your code is doing

rich bluff
#

interpolate it to player position

rich adder
dim sentinel
#

Ill try that

rich bluff
#

its a standard thing, camera rig being separate from the physical

dim sentinel
#

but even removing deltatime i still have it

# 
    private void CameraMove()
    {
        float mouseX = Input.GetAxisRaw("Mouse X") * sensitivityX * Time.fixedDeltaTime;
        float mouseY = Input.GetAxisRaw("Mouse Y") * sensitivityY * Time.fixedDeltaTime;

        if (cameraPlayer != null)
        {
            rotationY = mouseX;
            rotationX -= mouseY;
            rotationX = Mathf.Clamp(rotationX, -60f, 57f);

            cameraPos.localRotation = Quaternion.Euler(rotationX, 0f, 0f);
            rb.MoveRotation(rb.rotation * Quaternion.Euler(0f, rotationY, 0f));
        }
    }```

oh you are moving camera in Fixed?

rich adder
#

dont get inputs inside fixedupdate

dim sentinel

#

yes

#

want smooth camera do it in update

rich adder
#

store it in a V2 to use in fixedupdate

#

everything else looks fine (aside from cameramove not being in update)

summer stump
#

You will have to reduce the sensitivity a lot when you remove it btw

only line that should be in fixedUpdate rb.MoveRotation(rb.rotation * Quaternion.Euler(0f, rotationY, 0f));

Your rotation is set to one of those:

  • rb.rotation * sensitivityX
  • rb.rotation * -sensitivityX
  • 0
#

Is that what you want?

dim sentinel

I think its close to what I want

And yeah, there's no value in between, as that's the raw

dim sentinel

I can take a screen record to show you

willow scroll
dim sentinel
willow scroll

#

it doesnt make it embed weird is that only for mp4?

slender nymph
#

use mp4 to embed in discord

dim sentinel
#

so the camera is moving okay mostly but when rotating the rb it seems to jitter a bit and its more evident on moving objects

willow scroll
#

mkv embed is not supported

rich adder
# dim sentinel

this looks to be more related to your movement than rotation

#

as its more visible while strafing

dim sentinel
#

but its only when both of those actions happen at the same time

#

when moving or rotating isolated it doesnt happen

willow scroll
# dim sentinel

Are you talking about the player slightly jumping when running?

cam move in LateUpdate ?

which has rb.MoveRotation(rb.rotation * Quaternion.Euler(0f, rotationY, 0f)); ?

how it make sense to move Rigidbody on FixedUpdate but rotate it in LateUpdate ?

how

oh and you'd have to create your own accelerations/deceleration if you want that, but thats easy to do with Lerp/Animation curves

does anyone know how to write a script that would randomly swap the location of 3 identical gameobjects when a button is clicked?

yeah i think thats it because i typed a script before and that one didnt work and i probably didnt save after i removed

You should directly reference the object in the inspector

and put debug log inside that addlistener to see if it works

you can make that method public and drag&drop it to onclick even on the button directly in the inspecot

im starting a 2d game would it be easier making the map with textures and using a tilemap in unity or making it in gimp also would this effect the code?

depends on style of game levels 🤷‍♂️ also not code question

AddListener is much better imo

inspector is useful for UnityEvent that needs to be modular

If you have multiple scenes for different areas in your game, and you have for example an item, or ui, or an inventory screen, and you modify or update that item with new stuff on it,
how do you make that change be available across all levels so you dont have to go to every scene and carefully replicate the item/behaviour?

I just wanna say again thanks to everyone here who answers questions! After the other day I was reading and rereading the explanations you guys were giving me, trying out the things I didn't understand, and now I've got my code in a pretty nice place!

I'm essentially able to make any kind of ProjectileSpell from a single scriptable object now (and that spell can be set in the inspector for all sorts of things like speed, range, recoil, if it's explosive, the prefab and particle effects)

Then I can literally just slap that spell on my Players or Enemies SpellManager, and it all just works so nicely!

Next step I'm gonna expand and work on a DefenseSpell and MeleeSpell scriptable objects with the same principals

Someone that can help me identify the problem? why are the bullets not going forward on my player? its stuck on the spawnpoint, unless I bump into it then it goes forward. But the same method is used on the other 'enemy gun' that is shooting something.

Both objects (the player and the enemy in the maze) use this method, but its in different classes. But I cant pinpoint why its not going forward for the player. zzz

  public void ShootBullet(int ranPos)
    {
        tempBullet =
            Instantiate(bullet[ranPos], bullet[ranPos].gameObject.transform.position,
                bullet[ranPos].gameObject.transform.rotation); 
        Rigidbody tempRigidBodyBullet = tempBullet.GetComponent<Rigidbody>();

now this solution works, but im wondering, is there a way to convert to or get cords to Screen Space without referecing the canvas component? since its a type of Space like camera space maybe there is a way, this would be a little nicer since the fly effect is a prefab and id have to find the canvas gameobject ina scene since i cant reference objects in a scene

eternal needle
# scarlet skiff is that simply cuz var is easier to type than the type of the class?

Sometimes the line does get really long if you have to write the type out fully, and it's already fully visible what the type is in my example.
Otherwise it may just be confusing to others like
var x = someObj.MySecretFunction();
You have no clue what the type is from reading it, you have to mouse over it or look at the function declaration

var secret = new();

nice compile error

type cannot be inferred bla bla

funnily enough var x = GenericClass<>(); is allowed in java and it infers to the constraint

green copper
# timber tide doesn't matter besides who edits that asset last

the assets dont seem to be the problem, his version is just missing the scripts in the scene itself. If the deleted the bugged script references, version control offers to delete them off my machine as well but I don't want that, there's a lot of properties that'd need to be set again.

Is there a way for him to resync his editor with mine? My copy is working fine but his claims there are no pending changes that need to be made

How come my bullets are not firing forward to the point I'm looking at? even tho the pivot arrows rotate allong the way I rotate? I thought addForce(transform.forward, means its going to shoot on the green arrow axis. And I would think when reading the code, it will find the trans.pos + rotation, and based on those cords it will shoot something forward no?

   public void ShootBulletPlayer(int ranPos, GameObject gunPos)
    {
        Debug.Log("Shooting a bullet rn");
        tempBullet =
            Instantiate(bullet[ranPos], gunPos.transform.position,

        Rigidbody tempRigidBodyBullet = tempBullet.GetComponent<Rigidbody>();

Whats the best practice where to keep/hide the bullet objects? I fixed the issue on bullet shooting in 1 direction only but placing the objects under the players object, so it follows the players rotation. So I hid the bullets inside the gun. Got a hunch this aint smart cuz its putting a body inside a body, which will make them pop out of eachother. and hiding them under the world also feels wrong. Whats the approach for this lol.

Ight I got one last problem to take care of
There is a code to move boxes in the game, and also "Solar Panels" per say. I had a previous problem before (I assume with the button stacking) where E was used to both pick up and drop the box, but then it would bug on drop. I changed the drop to T, and now the boxes work, but said "Solar Panels" don't even get picked up anymore, and I'm unsure how I can fix this one

Cuz I made 3 types of bullets objects, and I spawn a clone of them each time I shoot. assuming I need to hide the parent bullet somewhere.

hi there,

I need some help in implementing basic topdown 2d movement. All the youtube resources I went through recommend using FixedUpdate for the movement itself, but that doesn't sit right with me since it looks terrible, the sprite obviously isn't moving smoothly and I'm not sure how to fix it

I've used lower level engines before and it was always way simpler to get this stuff to work, it was always some math multiplied by delta time to account for different framerates, but Unity has been giving me a lot of issues with that

    void Update()
    {
        float moveX = Input.GetAxisRaw("Horizontal");
        float moveY = Input.GetAxisRaw("Vertical");

        moveDirection = new Vector2(moveX * moveSpeed, moveY * moveSpeed).normalized;
    }

    void FixedUpdate()
    {
        rb.velocity = new Vector2(moveDirection.x * moveSpeed, moveDirection.y * moveSpeed);
    }

soo, how can I actually make it move each frame? (Moving the FixedUpdate contents to Update didn't work)

#

this is basically what I'm trying to achieve (minus the rotation stuff), this one was from a different engine

polar acorn
#

FixedUpdate is already framerate-independent, but if you want to work with per-second numbers, you can convert them to per-physics-step by multiplying them with Time.fixedDeltaTime

#

It won't actually affect the values, just let you work in human readable values like "units per second" to make the math easier to do in your head

uncut prawn
#

that still doesn't fix my issue with the choppiness though

#

I have a 144hz monitor, yet the sprite moving feels as if it was 60fps, which is super choppy looking

polar acorn
uncut prawn
#

essentially what you'd get if your fps was half of your refreshrate

#

kinda feels like it

#

instead of player movement that happens every frame, it looks as if it was skipping and only happening on some

naive pawn
#

oh whoops, confused you with another asker who was setting the position in FixedUpdate

short hazel
#

Try enabling interpolation on the Rigidbody2D if you haven't done that yet, it smoothes out the position between physics updates

uncut prawn
#

thank you!

short hazel
# uncut prawn thank you!

If I remember correctly, with this setting enabled, any modification made to the transform will be ignored (as it's now governed by the Rigidbody).
Modify the position and rotation via the Rigidbody directly

uncut prawn
#

oh that's really helpful, thanks for mentioning it

#

I'm implementing the rotation as we speak so I'll remember to do it through the Rigidbody

short hazel
#

The docs say that you can modify the transform, but if you do, immediately execute Physics.SyncTransforms() so the Rigidbody updates its own values

#

I don't know whether doing that is expensive, especially if you have a lot of physics objects in the scene

naive pawn
uncut prawn
#

hmm yeah that sounds expensive

short hazel
#

And that would be in Physics2D, since you're in 2D. But yeah use the rigidbody directly

uncut prawn
#

oke thank you!

short hazel
#

I love the docs

#

What does it do? It synchronizes.

naive pawn
#

lmao

uncut prawn
#

naive pawn
#

man, why do the 3d versions have such more detailed docs though

#

had issues with collider layers, 2d docs were absolutely useless, all the info i needed for that issue was in the 3d docs

short hazel
#

Ever tried to deal with collision contact points in 2D? Man the descriptions are so confusing. There's:

  • collider: The incoming Collider2D involved in the collision with the otherCollider.
  • otherCollider: The other Collider2D involved in the collision with the collider.
    OK but which one is my collider and which one is the one I just encountered
#

For 3D it's thisCollider and otherCollider and it's way clearer

naive pawn
#

wait, that's the opposite

#

that's cursed as hell

short hazel
#

Depends on how you interpret "incoming". For me it's the one you just collided with, but seems like it's not

uncut prawn
#

oh btw, any reason as to why this line would break movement? it basically introduced other choppiness and made it feel as if it's on ice

// update evt
rb.rotation = Mathf.Atan2(rotation.y, rotation.x) * Mathf.Rad2Deg;
naive pawn
#

incoming is the one that is not this one

short hazel
#

So 2D's otherCollider is yourself? wat

dunno man

all this physics stuff is messing with me, Im used to low level stuff and doing all the math myself

also just a sidenote, you might want to set angular drag to 0

short hazel
#

And set the rotation in FixedUpdate since it's now a physics operation

uncut prawn
#

wouldn't that mean that the rotation only updates every 50 frames?

short hazel
#

Yeah but you have interpolation. Continue polling mouse position in Update

uncut prawn
#

so basically most stuff is bandaided by interpolation?

short hazel
#

When you have a framerate that's much higher than the fixed physics timestep, yep

YieldInstruction

Description

Base class for all yield instructions.
why doesn't CustomYieldInstruction extend it then wtf

uncut prawn
#

like, I'm much more of a fan of running stuff per frame and adjusting the amount by deltatime

short hazel
#

Try in Update but with setting the Transform directly, call SyncTransforms() if you don't rotate or it behaves weirdly

#

Docs are not that clear on whether interpolation also affects rotation, but I'd say yes, since you can have angular velocity

uncut prawn
#

nope that doesn't work

#

well, part of me just wants to throw the physics features into the trashcan and do this stuff myself, would that be dumb?

#

or rather, isn't that one of the biggest parts of the engine? the physics engine?

short hazel
#

You'd have to detect collisions yourself in that case. Try with the rotation in FixedUpdate and if it doesn't feel good, trash the rigidbody and roll your own system

#

There's plenty of methods in Physics2D which allows you to detect what's around a specific point, but creating a good collision detection system is not an easy task

uncut prawn
#

sadly the FixedUpdate method feels way worse

#

I need that part to run at the framerate, since the game's main thing is meant to be butter smooth movement and player control

#

dunno what to do, I really dont wanna throw away 80% of what the engine offers if I was to do collisions myself...

Rigidbody interpolation stops for a tick if any transform changes are made. You can increase the physics tick rate if you want to increase responsiveness to input.

uncut prawn
#

I see, would it be smart or dumb to set the physics tick rate to the game's FPS and multiply stuff by delta time to have it be consistent across various framerates?

#

also would that affect the polling rate of inputs? I also need those to run per frame since the movement itself isn't as responsive as it should be

strong wren
#

I don't think physics engines like the tick rate being changed each tick. Input is generally evaluated at the start of each frame. Make sure to use the new input system to get the latest input backend improvements across platforms.

uncut prawn
#

right

#

one question, how much would I be alienating myself from most of the unity community if I just didn't use the physics system at all?

#

is it common that someone decides to go that route?

strong wren
#

Rolling your own is fine if you want to. Unity officially provides 4 different physics engines, with even more thirdparty solutions available 😛

also you should put a little more effort into your debugging. how you present your question

Want to play audio when shooting a gun. I want to use a variety of slightly different audio to make it non-repetitive. What's the suggested method:

  1. Have each shot audio in a separate file and then play one.
  2. Have all shots in a single file with a specific offset (e.g., second 1, 3, 5, 7, 9) and then always play from that index.
frosty hound
#

Separate files. The new upcoming version of Unity also has a new sound asset that let's you specify a list of sounds to randomly play from specifically for doing what you're asking.

#

Alternatively, you can do one shot and just change the pitch randomly with each shot.

Whats the best way to clamp the vertical rotation of something based on knowing the target position? I.e. head rotating to look at a target.

I am trying to pull the gun model toward a position behind it for a certain amount of time

#

but in Update()...

#

The program tries to keep the gun either at the aimed in position or the hipfire position

#

does the boolean shootCheck work as intended?

#

I rlly can't figure out how to "deactivate" that part of the code while the recoilAnimation() is running

Is there a physics event that gets called when 2 trigger colliders intersect? OnTriggerEnter only detects colliders

deft grail
#

that question doesnt really make sense to me

timber tide
#

If OnTriggerEnter fires then atleast two colliders do intersect

summer stump
timber tide
#

Ah, you want only trigger colliders eh

#

Probably just compare that the collider you are colliding with has IsTrigger enabled

That is not a dynamic rigidbody, it is a kinematic one

slender nymph
#

it is fine for OnTriggerEnter

summer stump
#

Oh dang. You right. Sorry.

I thought it needed TWO rigidbodies for kinematic. But the chart matches kinematic with static 🤷‍♂️

timber tide
#

you need atleast 1 rigidbody and 1 trigger

#

mix and match em

slender nymph
#

yep as long as any rigidbody is involved with the trigger overlap then it will fire OnTriggerXXX messages

glass ivy
#

weird, i've never had trouble with this, might be layers

glass ivy
slender nymph
#

that's kind of an odd way of describing it. what is actually happening is that any collider that is a child of a rigidbody becomes part of that rigidbody's compound collider so collisions and overlaps happen as a result of that parent rigidbody

i need another set of eyes at the end of the day 😅 ok... it's working, it's just late evening logic
