transform.rotation.y = object.transform.rotation.y

Would this work?

If the script was on the player

[verbal dome]

Well, you are supposed to replace object with an actual reference to the other object

Or just reference its transform directly

[brazen pagoda]

object is probably not an allowed variable name here

[fast relic]

no, because the rotation is a quaternion

[verbal dome]

And no, rotation.y is not correct, you want to use euler angles

[west sonnet]

Yeah, I just put object for the sake of this answer

[limber flower]

ok im getting a lot of different answers at once here

[verbal dome]

@limber flower Replace object.transform with a transform reference of the other object and use this

[limber flower]

{
    public Transform orientation;
    void Start()
    {
        
    }

    // Update is called once per frame
    void Update()
    {
        Vector3 euler = transform.eulerAngles.y;
        euler.y = orientation.transform.eulerAngles.y;
        transform.eulerAngles.y = euler;
    }
}```
is this what i need to do?

[verbal dome]

Looks alright

orientation.eulerAngles is enough, no need for .transform.

It's already the transform

[brazen pagoda]

^ this. Otherwise looks good to me as well

[fast relic]

you're setting euler which is a Vector3 to only the y component of the rotation, even tho it should be all of it

[limber flower]

orientation.eulerAngles.y has red squiggles under it

[fast relic]

you don't need the y

[verbal dome]

Ah yea

[brazen pagoda]

Oh good catch didn't notice that

[limber flower]

ah ok

thank you everyone im going to test it now

[verbal dome]

Oh my bad it was in my example 😆

[limber flower]

that did not work

[verbal dome]

Did you aassign orientation?

[limber flower]

i did set the orientation object

[verbal dome]

If this doesn't work then likely something else is modifying its rotation

[brazen pagoda]

Did you put the script on the object you want to be rotated?

[verbal dome]

Could be a script, could be an animator

[limber flower]

yes

[fast relic]

is it just doing nothing or doing something that you didn't expect it to

[limber flower]

the model is always facing one direction, but the actual player object which has the movement script still faces the camera direction

[fast relic]

make sure that that code runs at the end of the frame, after the player's rotation gets set

[limber flower]

at the end of the frame?

idk what that means

[fast relic]

if it runs before the player's rotation gets set it's gonna do nothing because it's overwritten right after

put that bit of code at the end of the script that's setting the rotation

[verbal dome]

Basically the game is updated once every rendered frame.
The rotation that is last assigned to the player in that frame will be what you will see in the game

[limber flower]

wait could it be that the armature's rotation is overwriting the rotation im trying to put on the playermodel?

[verbal dome]

Yes, I did mention that animator is possibly changing its rotation

[limber flower]

i dont have any animation on it

[verbal dome]

You have other code that rotates the player too, right? Show that

[limber flower]

how do i check which rotation is last assigned

[limber flower]

one momment

[verbal dome]

You pretty much just gotta know/search your code

[limber flower]

{
    public float sensX;
    public float sensY;

    public Transform orientation;

    float xRotation;
    float yRotation;
    private void Start()
    {
        Cursor.lockState = CursorLockMode.Locked;
        Cursor.visible = false;
    }
    private void Update()
    {
        float mouseX = Input.GetAxisRaw("Mouse X") * Time.deltaTime * sensX;
        float mouseY = Input.GetAxisRaw("Mouse Y") * Time.deltaTime * sensY;

        yRotation += mouseX;

        xRotation -= mouseY;
        xRotation = Mathf.Clamp(xRotation, -90f, 90f);

        transform.rotation = Quaternion.Euler(xRotation, yRotation, 0);
        orientation.rotation = Quaternion.Euler(0, yRotation, 0);

    }

}```

[limber flower]

this is the camera orientation code

[verbal dome]

If you have two scripts with an Update method, they run in a random order so don't rely on that. In one game session the other update might run first and vice versa
LateUpdate is guaranteed to run after all Updates though.

[limber flower]

actually i dont think the player is actually being rotated technically

its just applying a force in a different direction based on the orientation object which is controlled by the camera script

[verbal dome]

Btw https://unity.huh.how/mouse-input-and-deltatime

Very common mistake

You get smoother/more consistent mouse input if you fix that

But not related to your question

[sour fulcrum]

You mean instances in this message when you say script yeah?

[limber flower]

ill keep that in mind for after i sort this out

[verbal dome]

I think it's more per-type, not per-instance

[sour fulcrum]

per instance is more or less random

per type is controllable if defined and while it can shift between dev builds due to some things, it won't be random per session

[limber flower]

anyways this is what controls the movement relative to camera orientation
moveDirection = orientation.forward * verticalInput + orientation.right * horizontalInput;

[verbal dome]

Yeah you can configure the execution order manually

[limber flower]

i cant tell if that is actually rotating the object or not

[verbal dome]

Maybe per session was incorrect, but still wouldn't rely on it if it might change due to some seemingly random circumstances

[sour fulcrum]

just being a nitpicky nerd dw

[verbal dome]

All good :p

[limber flower]

putting the script on the armature also didnt affect it

[verbal dome]

How does your object hierarchy look like?

What objects are children of what?

[brazen pagoda]

Try testing the script on some independent new object that has no other code associated. Just to confirm whether the script works

[limber flower]

heavyplayerWIP is the character model

[limber flower]

still nothing

[brazen pagoda]

Then there's either an issue with the script itself or the orientation object doesn't do what we think it does

[verbal dome]

Orientation is a child of the player so the player following its rotation would cause a feedback loop anyway 🤔

Because the child rotates with the parent

[fast relic]

are you sure y is the axis you need?

[limber flower]

as long as the y axis is what makes things turn left and right im sure

would it help if i found the tutorial i got the movement code from?

and then told you how ive changed it

[fast relic]

just making sure

[naive pawn]

yep yaw axis

[limber flower]

is that why its called yaw?

[naive pawn]

not because of "y", no

[limber flower]

oh ok

[naive pawn]

there's yaw, pitch, and roll

[limber flower]

yeah i only knew that because ps3 minecraft had pitch and yaw sensitivity instead of x and y

https://youtu.be/f473C43s8nE?si=8imXlgJ_eS2_GMmm

this is where the movement code is from

[naive pawn]

x/y sensitivity would refer to movement of a mouse, whereas pitch and yaw would refer to the actual rotation
assuming y-up, x-right, z-forward:

• pitch is rotation about the x axis
• yaw is rotation about the y axis
• roll is rotation about the z axis

[brazen pagoda]

Usually aerodynamical terms referring to rotations along certain axes of a long object. Roll being rotation around longitudal axis etc.
It's not normally affiliated with world-space XYZ.

[verbal dome]

Really wish that "Dave" would pin a comment about the mouse deltatime issue on that video

Mate has 1.2mil views, that should bring some responsibility

[naive pawn]

it isn't world-space xyz to begin with, in this context it's around the local axes

[limber flower]

he also forgot to mention to add a whole "x = true" statement in the video

[naive pawn]

roll is around the "forwards" direction of the object

[brazen pagoda]

Yeah I get that, but it's still not longitudinal, transverse and normal axes 😅 There's some language inaccuries by applying a physical inertia/velocity based naming scheme to an aiming context where Horizontal/Vertical is likely more accurate terms. Roll is the least effort rotation since it's longitudal axis is the axis with least angular intertia on airplaines, rockets, submarines etc. On a standing character, that would be rotation around the y-axis if accurate, thus ambiguity when putting it on the z axis that a plane typically has.

But it's all semantics so not super important. Just thought I'd mention.

[naive pawn]

🤔 but generally the longitudinal axis is the direction of travel, isn't it?
since it would present the least cross-section, hence the least drag
i think the "direction of travel" is a reasonable fixed point to use when using those terms in this context where moments of inertia don't really apply

[limber flower]

setting the orientation object to the actual player camera also doesnt work

[naive pawn]

(that's the interpretation i use, here i'm trying to challenge that to see if that holds up)

[limber flower]

typically longitude and latitude are just north-south and east-weat

[naive pawn]

not what we're talking about

"longitudinal axis" just means the long axis of some object
the longitude value used in geographical coordinates is also based on that, it's the long way around the earth

[brazen pagoda]

A plane can be stalling or slipping/skidding, terms describing situations where direction of travel differs from the orientation of a plen. The three axes remains fixed to the plane in each of those cases afaik.

There's some science I'm thinking about back in the days about rotational stability where in mechanical physics we would describe the three axes of a wooden plank based on it's inertia. There's also a very interesting physics video by Veritasium about "The Bizarre Behavior of Rotating Bodies" describing how two of the three princple axes are stable axes when rotated, but instability around the other. Aka the "intermediate axis theorem". However I must admit "intermediate axis" isn't one of the 3 I mentioned so I'm now a little unsure what's completely correct here tbh But a lot of axis talk starts at inertia. And a "long" axis tends to be the axis with leas angular inertia, i.e. the one that requires the least force to rotate.

TL;DR: I'm a bit unsure right now

[naive pawn]

i mean the intended primary direction of travel lmao
this would get even more complicated with like, helicopters 😂

[brazen pagoda]

Haha yeah good mention

[naive pawn]

ive seen the veritasium video before, yeah. the intermediate axis would be either the vertical or transverse axis, wouldn't it? just depending on the craft

wait no

[fast relic]

is it common for this chat to start talking about like helicopters or something or is this just a one off lmao

[naive pawn]

the intermediate axis should always be the transverse axis, shouldn't it 🤔

[limber flower]

It's a one iff

[naive pawn]

but for something like a submarine with minimal "wings" and also the top part, the transverse axis and vertical axis would be quite similar, so maybe my initial guess was right

[limber flower]

I still haven't figured out my problem

[naive pawn]

[naive pawn]

oh whoops, thought you solved it. what was your problem again? (link the original question or something)

[limber flower]

I can't figure out how to set my player model to rotate with the camera (on the y axis)

[brazen pagoda]

To be fair I have tried coding some helicopter stuff. In real life it's one of the hardest vehicles to control properly, but in a game it's relatively simple and probably the most convenient vehicle you can make in order to explore and navigate your open world designs Almost like creative mode Minecraft

[verbal dome]

Are you absolutely sure that you don't have other script components that could be rotating your player?

[limber flower]

I'm not really sure but I've looked through all of it and I can't see anything that's doing it

[naive pawn]

so the camera is controlled directly by your mouse and then you want the player to rotate according to the camera movement?

[limber flower]

The player moves in whatever direction the camera is facing, I can't tell if the player is actually rotating or not, but I want the 3d model attached to the player to rotate with it

see the section on large code blocks

[limber flower]

oh ok

https://paste.mod.gg/sjzunmgqlghr/0

the movement script

[naive pawn]

look in the scene view or the inspector and see if it's actually rotating

[limber flower]

i can see the model below the camera in play (another problem i need to fix)

[verbal dome]

rb.freezeRotation = true;

👀

[limber flower]

oh my

why is that even there

[verbal dome]

We should just always ask for the full script

Oh this is a completely different script

[limber flower]

if i turn that off, will it rotate in every direction?

[verbal dome]

You can freeze the X and Z axes only, if you want

[limber flower]

well its a script attatched to a parent of the the character model

[verbal dome]

No need to do it via code tho, just set it in the inspecotr (Rigidbody > Constraints tab)

[limber flower]

that makes even less sense actually

why would they tell me to add that if you can just do it in inspection

well that still didnt fix it

[naive pawn]

tutorials aren't gospel

[naive pawn]

did you also remove the freezeRotation line in code (and saved and recompiled)

[limber flower]

yes\

[naive pawn]

also, if you have an rb, that's gonna try to manage the rotation, so you'll have to tell the rb to rotate

[limber flower]

oh right

but it can definitely rotate now

the model fell over when i tried to move because i didnt lock x and z rotation

[naive pawn]

ok, then lock those axes lmao

[limber flower]

yeah still cant get it to work

the rotate script just doesnt do anything as far as i can tell

[raw smelt]

Hi why if i do that

                SystemAPI.SetComponent(BulletEntity, LocalTransform.FromPosition(localTransform.ValueRO.Position));
                SystemAPI.SetComponent(BulletEntity, LocalTransform.FromScale(bullet_size));

The size is corret but if i did that

SystemAPI.SetComponent(BulletEntity, LocalTransform.FromScale(bullet_size));
                
SystemAPI.SetComponent(BulletEntity, LocalTransform.FromPosition(localTransform.ValueRO.Position));
                

is not

[limber flower]

LocalTransform.FromPosition(localTransform.ValueRO.Position));

this just affects position

[wintry quarry]

#1062393052863414313

[limber flower]

LocalTransform.FromScale(bullet_size));

but this affects size

as far as i can tell

[raw smelt]

I know but why if i make
A ,B
i have dif effect than
B, A

[limber flower]

oh ok

no idea

[verbal dome]

I assume that's because the scale affects the local position

But yeah it's a dots question

[limber flower]

are there not any voice channels in this server where i could share my scree?

that would make this a lot easier

[fast relic]

just turn off your mic

[limber flower]

pardon?

[naive pawn]

no, it's not a particularly effective way to give info

[limber flower]

seems more effective than just guessing what might be helpful

[raw smelt]

But screen share will be a perfect way (:

[naive pawn]

it would not

[raw smelt]

Why not ?

[naive pawn]

everything you share is ephemeral

[raw smelt]

pair programming is greate

[naive pawn]

anyone trying to help won't be able to go back to see what you just showed

and anyone trying to help later, just won't be able to

[limber flower]

thats a good point

[brazen pagoda]

VSCode Live Share combined with screen share
(Might be risky) - Allowing others to run code - don't do it if you don't know what you're doing

[polar acorn]

Because people just showing up partway who might have the answer won't be able to just scroll up and see what the question was

[naive pawn]

well that just seems redundant

[naive pawn]

maybe, but community programming is not gonna be possible in this way lmao

[limber flower]

i hadnt even considered that

[raw smelt]

why not ? make 5 dif voice chat rooms at that sall

[naive pawn]

that's also why text/images are better than video/audio explaning the issue (video demonstrating the issue is fine, describing the issue isn't great)

[brazen pagoda]

I think other than sharing individual scripts here the least effort on the end of those providing assistance is to provide a github link to a branch that has the issue in question, along with some pointers where to look.

[naive pawn]

that's not the issue
the issue is that it negates the benefits of a community server, where people can come in whenever to help
and that might be later in time when you aren't available

[polar acorn]

(This was supposed to be the part where I reply to the original question with an answer to prove my point but it's a dots question lmao)

[limber flower]

regardless, i still just need someone more experienced with unity to be able to see everything i can see because i have no idea whats important to share or what causes what reaction

[naive pawn]

(with text/images, you can just look up to go back. with audio/video, you have to scrub through and wait to actually listen)

[naive pawn]

nah, that'd just be a lot of unnecessary info

you know your project better than we do

[polar acorn]

When you ask a question, provide what you think is most relevant, then provide more upon request

[naive pawn]

what are the relevant components you have? rigidbodies, colliders, etc
what's the hierarchy? etc

[limber flower]

currently my project is just the player character on a platform

[polar acorn]

What is the current issue? Reply chain went cold before I found it

[limber flower]

basically i need to add a script that turns the playermodel with the camera

and i dont know how to do that

[polar acorn]

As in, like, the camera swings around the character and the characters back is always facing the camera?

[limber flower]

the playermodel is constantly facing the direction it started at, and the camera moves indipendantly from it

[brazen pagoda]

I think it's easier if you reverse that. Rotate the camera with the player instead.

[limber flower]

i think i can do that

[polar acorn]

Okay, and you want it to face in the direction the camera is pointing then?

[brazen pagoda]

Is the camera following the player as well? If the player moves right, does the camera move right?

[limber flower]

yeah and pressing w always moves in the direction of the camera

it seems the code i currently have, rotates the camera, and moves based on that, without affecting what the camera is attatched to

[polar acorn]

Yeah, seems to me like you should have your controls rotating the player and then have code that moves the camera to be behind the player (or just let Cinemachine handle that)

[limber flower]

i have a camera position obj stuck to the player head that the camera moves with

so take the y axis controls from this script

 {
     float mouseX = Input.GetAxisRaw("Mouse X") * Time.deltaTime * sensX;
     float mouseY = Input.GetAxisRaw("Mouse Y") * Time.deltaTime * sensY;

     yRotation += mouseX;

     xRotation -= mouseY;
     xRotation = Mathf.Clamp(xRotation, -90f, 90f);

     transform.rotation = Quaternion.Euler(xRotation, yRotation, 0);
     orientation.rotation = Quaternion.Euler(0, yRotation, 0);

 }```
 and put it in the playermove script?

[brazen pagoda]

There are many ways to approach this.

• Cinemachine is the most elegant and powerful tool here.
• Parenting: Make the camera a child of the player object, and give it some offset. This way it will rotate if the player rotates.
• Constraints. You can add various constraints to provide offset and aiming directions without parenting.
• Code everything

[limber flower]

im unsure how to proceed with this information, it could be very easy to do it wrong and undo a lot of progress

[polar acorn]

So make a backup and then experiment to your hearts content

Sometimes the best way to learn is to irrevocably break things

[limber flower]

what lines do i need to remove from this to make it not have any y axis controls

[brazen pagoda]

I kinda just started a fresh project myself and I need to do something a bit similar. If you wanted someone to hop on some screen share we could probably do it together

[naive pawn]

i'd recommend against the private support, as it negates the benefits of a community server existing, but if you want to do that personally, i can't stop you 🤷

[naive pawn]

all the parts dealing with the mouseY and yRotation?

[limber flower]

including these?

     xRotation -= mouseY;```

[naive pawn]

ah. mouseX is up-down, isn't it lmao

[limber flower]

yeah

[naive pawn]

wait no

mouseX is left-right and you use that to move around the y axis

ok

yRotation is the main one; you would remove that and stuff related to it
so that would be mouseX

[limber flower]

like this?

 {
     float mouseY = Input.GetAxisRaw("Mouse Y") * Time.deltaTime * sensY;
     xRotation -= mouseY;
     xRotation = Mathf.Clamp(xRotation, -90f, 90f);

     transform.rotation = Quaternion.Euler(xRotation, yRotation, 0);
     orientation.rotation = Quaternion.Euler(0, yRotation, 0);

 }```

[naive pawn]

you're still using yRotation

your ide should tell you about that

is your ide configured?

[limber flower]

ide?

oh ok i see what you are saying

yeah i got rid of the yRotations at the bottom

[naive pawn]

the thing you're coding in

!ide

[eternal falcon]

💡 IDE Configuration

If your IDE is not autocompleting code
or underlining errors, please configure it.

Select one:

• Visual Studio (Installed via Unity Hub)
• Visual Studio (Installed manually)
• VS Code
• JetBrains Rider
• :question: Other/None

[limber flower]

yes it did tell me that

[limber flower]

i just wrote this in discord

but when i put it in visual studio it told me

[naive pawn]

you should just do it in your ide

[limber flower]

well now the model does turn with the mouse

but the camera doesnt turn left and right

[naive pawn]

ok, so now you just have to get the camera to follow the player

[limber flower]

couldnt i technically just have the same y axis script on the player and the camera?

or would that cause issues

[brazen pagoda]

Parenting it in the hierarcy is likely easiest if that works for you

[naive pawn]

you could, but you should just follow the player

either through hierarchy like chexxor mentions above, or through some follow script (of your own, or via cinemachine)

[limber flower]

i was told attatching a camera to a rigidbody would be problematic

[brazen pagoda]

I have never seen problems with that so far

[raw smelt]

Can I make the game always run at 60 fps, and if it can't generate 60 fps, make everything slow down but keep consistency, for example, the shooting frequency, intact ?

and still use Unity Physics etc

[brazen pagoda]

Might be some special case Like large number positions due to floating point precision perhaps. Don't know what else should cause issues. I mean if you're doing a physics sim you could see some janky behaviour. But if you're doing a character controller and not a bouncing ball you should be fine

[limber flower]

i put the camera holder under the player and it still doesnt rotate on the y axis

[brazen pagoda]

So the "Player" rotates but the camera doesn't?

[limber flower]

yes

[brazen pagoda]

Then you have a rotation freeze or rotation overwrite from code somewhere

[naive pawn]

that's what deltaTime is for

[naive pawn]

floatingpoint wouldn't cause any special cases for rigidbodies specifically

[raw smelt]

But for example i have weapon shooting 10 times per s
So if i will don't get 10 frames it will not shoot 10 times

or it will not be in exacly 1/10 s interval

[naive pawn]

if you have a framerate that isn't divisible by 10 then you won't get exactly 1/10 anyways

[raw smelt]

actually why not ?

i can save the "extra time"

for example

[naive pawn]

if you have less than 10 fps, you could just make it shoot every frame

[raw smelt]

but i can miss every 2 frame

[brazen pagoda]

Here's a fresh example. No code - just hierarchy and me rotating the "Player".
Camera rotates with the player here.

[raw smelt]

if even frema will be faster that old frame

then i will get like
1 - shoot
2 -not shot (becouse is less that 1/10 s )
3 -shoot
4 - not shoot
...

[limber flower]

i see

[raw smelt]

so i will get 5 shoots in 1 s ineasted of 10 even if i have 10 fps

[naive pawn]

if you have 60 fps, and shoot 10 times per second, you get 1 shot every 6 frames (60/10). 6 frames / 60 fps = 0.1s
if you have 59 fps, and shoot 10 times per second, you still get 1 shot every 6 frames, because you can't shoot between frames
so you get 6 frames/59 fps = 0.101... s

[brazen pagoda]

So assuming that the code you already have does the same thing to the "Player" rotation as I am doing through the inspector, you would have the same camera motion unless something else is interfering.

[naive pawn]

so just don't worry about getting exactly 0.1s per shot

just make sure it's >= 0.1s per shot, and everything will work out fine

[limber flower]

ok this is weird, the camera cant even rotate on its own accord anymore, i got rid of the "//" on the y axis code to make it work again, and theres still no y rotation

[raw smelt]

DPS of weapon can change a lot

[naive pawn]

is your game gonna be multiplayer?

[raw smelt]

if i want make kind of TD defens
Then its importnat

becouse you will get for example +20 % dmg upgrade
and you lose it becouse of unlucky frame rate XD

[naive pawn]

no, that's not what will happen

[naive pawn]

answer this

[brazen pagoda]

Do you have scripts on both the camera and the player at the moment? If so, try disabling all scripts on the camera temporarily to see if that un-freezes the camera.

[naive pawn]

it won't matter, but why it won't matter will be different

[naive pawn]

it shouldn't rotate on y on its own, no? it's just following the player

[raw smelt]

not It will not . Actually now I mainly learny how to use Unity etc
So I try make Protype of protype

[limber flower]

yeah thats the end goal, but i wanted to see if it could, to try and narrow down where the rotation lock is coming from

[naive pawn]

right, then it won't matter. if you're lagging, everything else is lagging
dps in real time will be less, but damage per frames, or per-in game time, will still be the same

you shoot slower, but enemies also move slower

if you have a frame rate less than the fire rate, you can just make it fire multiple times per frame to make up for the lost frames where it shoudlve shot

[raw smelt]

But that means that i have to change move system

[naive pawn]

your move system should already rely on deltaTime 🤨

[raw smelt]

Becouse Enemy will move by Unity Phisic sistem

[raw smelt]

Yep and this is a problem

[limber flower]

something in this is causeing the rotation lock

{
    //public float sensX;
    public float sensY;

    public Transform orientation;

    float xRotation;
   // float yRotation;
    private void Start()
    {
        Cursor.lockState = CursorLockMode.Locked;
        Cursor.visible = false;
    }
    private void Update()
    {
       // float mouseX = Input.GetAxisRaw("Mouse X") * Time.deltaTime * sensX;
        float mouseY = Input.GetAxisRaw("Mouse Y") * Time.deltaTime * sensY;

      //  yRotation += mouseX;

        xRotation -= mouseY;
        xRotation = Mathf.Clamp(xRotation, -90f, 90f);

        transform.rotation = Quaternion.Euler(xRotation, 0, 0);
        //orientation.rotation = Quaternion.Euler(0, yRotation, 0);

    }

}```

[naive pawn]

why not use that for shooting too?

[raw smelt]

Becouse Enemy will move to you faster than your gun shoots

[naive pawn]

if you use fixedupdate for the gun, then this won't be an issue

[naive pawn]

im confused, what's the current issue now?

[raw smelt]

It will becosue Enamy change posionon is
Speed * deltaTime
imagine 1 fps
so enamy will travel for example 1 m
and you weapon will shoot only 1 time
if 10 fps
enamy will still travel 1 m
but weapon will shoot 10 times

[naive pawn]

that the camera isn't rotating in pitch?

[naive pawn]

if enemies are using fixedupdate, then framerate isn't relevant at all

[limber flower]

the cameras y axis is locked, unless i disable the code that makes it rotate on the x axis

[raw smelt]

Its not for move But its for weapon XD

[raw smelt]

so This is a problem

[naive pawn]

which is why im saying to use fixedupdate for the weapons, too

[raw smelt]

If you will make Enamy move in
meter/per shoots
then you will get "faster Enamy " if you have low fps

[naive pawn]

what do you mean by "locked"?

[brazen pagoda]

Oh, so the code that rotate's on X-axis doesn't copy the current y-axis then.
You cannot "just" set one axis of rotation - you have to set the entire rotation.

[naive pawn]

is it rotating with the player or not?

[brazen pagoda]

It's a common mistake

[naive pawn]

not really, no

[brazen pagoda]

So if you only want to set a single axis of rotation the general process is:

1. Copy existing rotation
2. Change only the axis you want to change
3. Set the modified rotation

[naive pawn]

the entire point of deltaTime is to keep everything consistent in time

[brazen pagoda]

If you forget step 1. then you will not be preserving the other axes, you will instead overwrite them, which I suspect you're doing right now.

[raw smelt]

Wait if game have 1fps (extream but easy )
And weapon shoot 10 times per secen

it will fire only one becouse there is only 1 update ?

[naive pawn]

ah, ok

@brazen pagoda there's an easier fix

[limber flower]

so how do i set the entire rotation, while keeping the y rotation controlled by the player

[naive pawn]

just use localRotation instead of rotation, so the yaw is inherited from the parent

[naive pawn]

or, just use fixedupdate, because there will still be 50 fixedupdates

[brazen pagoda]

Yeah that's fair, if the local Y is always 0 Which it should be here

[raw smelt]

How its possible if computer can't make 50 uptates ?

[brazen pagoda]

Good point

[raw smelt]

The time will slow down ?

[naive pawn]

or, as i said before, emulate the same behavior yourself, but calculating how many shot shouldve happened in the deltaTime time window

(wrong reply, sorry; meant to reply to my own message)

[raw smelt]

Still not good becouse i don't know when enamy get into a range

[naive pawn]

basically, yes. fixedupdate will run however many times it needs to to catch up

[limber flower]

where do i use localRotation here

{
    //public float sensX;
    public float sensY;

    public Transform orientation;

    float xRotation;
   // float yRotation;
    private void Start()
    {
        Cursor.lockState = CursorLockMode.Locked;
        Cursor.visible = false;
    }
    private void Update()
    {
       // float mouseX = Input.GetAxisRaw("Mouse X") * Time.deltaTime * sensX;
        float mouseY = Input.GetAxisRaw("Mouse Y") * Time.deltaTime * sensY;

      //  yRotation += mouseX;

        xRotation -= mouseY;
        xRotation = Mathf.Clamp(xRotation, -90f, 90f);

        transform.rotation = Quaternion.Euler(xRotation, 0, 0);
        //orientation.rotation = Quaternion.Euler(0, yRotation, 0);

    }

}```

[naive pawn]

cool, just use fixedupdate then lmao

[brazen pagoda]

When you do transform.rotation = ... that is effectively setting the entire rotation. If you tried doing transform.rotation.x = ... you would get an error.

What Chris suggested is to change transform.rotation = ... into transform.localRotation = ... which would solve the problem

[raw smelt]

so if my computr can make only 1 Fixeduptade per sec
then deltaTime will be smaler ?
After 1 s it will be less that 1 s becose Fixedupdate "slow down a time " ?

[naive pawn]

@raw smelt if your game is going to 10 fps regularly, you have more pressing issues

[limber flower]

ok thank you

[naive pawn]

if your computer can only run 1 fixedupdate per second then it won't be able to meaningfully run any part of the game

[raw smelt]

ITs just easy number man i know i don't want to make game in 10 fps XD
But its easy for calculation than 78 fps

[naive pawn]

you're worrying about issues that don't really exist

[brazen pagoda]

The thing that was freezing the camera rotation is the 0's you added in Quaternion.Euler(xRotation, 0, 0); which would always set that rotation to 0, which would reset any value that was not 0 from before.

But with localRotation, setting to 0 just means "0 degrees difference from the player" since "local" means it's rotation relative to the parent/player.

[cosmic dagger]

What is your actual problem?

[raw smelt]

Man i ask that too understand system not to give a realistic number

[raw smelt]

prive ? i don't wanna spam too much XD

[naive pawn]

if your computer can only run 1 fixedupdate per second it'll just hang. or maybe there's a max amount of iterations that fixedupdate can run, as a fallback measure

it's an insanely unrealistic scenario, you won't be able to learn anything from that lmao

fixedupdate runs at 50 Hz by default. if you have 25 fps, then it'll run fixedupdate twice per update (or per frame)
does that make more sense?

[raw smelt]

Man i can if you really wany i can give you example of losse 49% dps for 120 fps too XD but it will be harder to make example

[naive pawn]

if you have 10fps, it'll run 5 fixedupdates per frame

[cosmic dagger]

It compensates for the drop in fps to match your number of updates (from the project settings), that's pretty much it . . .

[raw smelt]

What do you thing about make no deltatime and make max fps 60 ?

and no deltatime at game at all ?

[naive pawn]

@raw smelt are you actually worrying about a potential issue, or are you curious about the system? you're giving very mixed signals here

[raw smelt]

Both XD

[naive pawn]

that just doesn't make sense

[naive pawn]

there is no issue here, end of story for that first part

deltaTime is for keeping game time and real time consistent

if you think updates won't happen frequently enough, then use fixedupdate

[raw smelt]

Why not
if i will do it that way
I will know that weapon will shoot exacly 5 times per 12 frame for example
and my Enamy will move 0.4 m during 12 frame

so i know that i can shoot him exacly 5 times before it will move 0.4 m

[naive pawn]

so you still have deltaTime

you just hardcode it instead

[cosmic dagger]

This doesn't make sense. You need to know the time it took the last frame to run . . .

[raw smelt]

Why ?

[naive pawn]

deltaTime is just the time between Updates or FixedUpdates

[raw smelt]

i can make just 60 fps game ?

[naive pawn]

then you're just hardcoding a deltaTime of 0.016

you still have a deltaTime

[raw smelt]

and if you can have 60 fps game work good and if you have less than 60fps your game will slow down (and in game time too )

[naive pawn]

you can't not use deltaTime if you have anything in your game that relies on time

[fast relic]

yea but why would you want it to slow down

[raw smelt]

To make consistance DPS of weapons for example

[naive pawn]

sure, that's an option
but you still have deltaTime, just not a dynamic deltaTime

[naive pawn]

so 30fps just gets half time permanently? lmao

[fast relic]

that'll make it not consistent

[raw smelt]

Yep

[naive pawn]

that's a terrible experience

and that's what dynamic deltaTime fixes

[cosmic dagger]

Anyone can. Use good coding practices, check the profiler when you have performance issues. Optimize your models or sprites, textures, etc . . .

[raw smelt]

It will
DPS but secend is defin by number of frame 1 secen in game is exacly 60 frame

[fast relic]

no, a second is defined as a second

not 60 frames

[raw smelt]

in game secend

[naive pawn]

no, you get consistent dps in game time but not in real time

getting consistent in real time is more important for player experience

[raw smelt]

DPS of weapon is actually Damge Per Secend (in game secend)

[fast relic]

but why would you want ingame seconds? we don't live inside the game

[naive pawn]

that's just not a real metric

[raw smelt]

So if you have weapon X
it will kill enamy before it will kill you ALWAAYS
And not only if you have more that 68 fps ?

[naive pawn]

i have no idea what you're talking about anymore

[fast relic]

same tbh

[naive pawn]

deltaTime makes things not reliant on framerate

so if you use deltaTime properly, fps just doesn't matter

[raw smelt]

But you have to call a "shoot" function

[fast relic]

yea

[raw smelt]

and you call it not more time that a number of updateds

[naive pawn]

and, like ive mentioned, you can call it multiple times per frame

[naive pawn]

that's just causing problems for yourself

[cosmic dagger]

Either way, there isn't an actual problem here. You're just describing how you want to shoot and potentially damage an object . . .

[naive pawn]

if you want to shoot 80 times per second, and you have 60 frames per second, you will have to shoot twice on some of those frames
same if you want to shoot 20 times per second and you have 15 fps

so, just shoot multiple times on those frames

or if it's less than 50 (or the physics tick rate, if you've changed it), you can just use fixedupdate

[wintry quarry]

The really clutch thing is positioning the projectiles as though they were fired inter-frame too

[raw smelt]

Yep i was thinking about that too

[naive pawn]

either way, in the original scenario where you have weapons in update and enemy movement in fixedupdate, that's the issue, not a difference in framerate
if you want them to interact well, put them on the same loop. either both on update or both on fixedupdate.

[raw smelt]

But then i have to be sure that actuall enamy will not be overshoot for example (beocus its too close XD )
or i have to know if enamy was present in range of weapon the whole time

[brazen pagoda]

So I think the issue you're thinking of is "critical numbers". As an example I wanna suggest an analogy just to explain what I mean by critical numbers:

A common example is if a little change in one number causes a big (critical) change in something else.
This typically occurs as a side-effect of discrete numbered systems - like "Frames" in this case.

But another discrete case example is "number of shots" or "number of sword swings" etc.
In a game you might have enough damage to kill an enemy in 2 hits. Let's say an enemy has 51 HP and you have 50 damage. But if you get +1 damage you can now do it in 1 hit.

So a +2% damage increase made you 100% more effective in combat.

So I think Piodd here is thinking about the scenariou where a change in FPS might change the number of Bullets are fired for a number of times.

[raw smelt]

becouse maybe enamy get into range in 0.000001 ms before frame XD so it shoot get only 1 shoot not 2

[naive pawn]

this is a problem that doesn't exist

[wintry quarry]

yes indeed. Lots of complications here 😄

[naive pawn]

but if you're hellbent on making it one, just use fixedupdate

[wintry quarry]

can be solved with some raycasting

[brazen pagoda]

This is a real issue if you're developing a game where determinism is important, and also if you have a multiplayer game where staying in sync is real.

This is why some games, specially RTS games (my speciality) used a method called "Lockstep" which among other things ensure fixed time steps with fixed delta times.

I recommend looking that up to understand the problem space more deeply.

[naive pawn]

like, say, fixedupdate?

[brazen pagoda]

No Fixedupdate is just an approximation

[raw smelt]

I think about kind of TD gams (but i know i am not close to even start that for now i will give myself a time before i will even make prototype of prototype XD )

[brazen pagoda]

If FixedUpdate was 100% fixed, you wouldn't have FixedDeltaTime

[naive pawn]

is it though? it's simulating at 50Hz

[naive pawn]

fixedDeltaTime is pretty much a constant

[cosmic dagger]

None of this is actually true, as it has yet to happen. It's all circumstantial. What's the point?

[brazen pagoda]

"Pretty much" does not meet the standard of "determinism"

[naive pawn]

you can configure how often fixedupdate runs

[raw smelt]

Yep if you have "anty rezonanse " XD you can get for example miss 1:5 shoots even with big fps

[naive pawn]

ok, and if you never change the tick rate?

[raw smelt]

And that will be like 20% dmg

[brazen pagoda]

If you run multiplayer games that need to stay in sync, then you need 100% perfect sync because any error will accumulate over time. So you need every single calculation to be the same even if they are running on different machines.

Or you need to constantly be fixing the desync

[wintry quarry]

FixedUpdate is guaranteed to run the prescribed number of times over an extended period. What it's not guaranteed to do is run at exactly the prescribed interval

[brazen pagoda]

^ Fixing desync is fine in some cases

[naive pawn]

if you don't, fixedDeltaTime will be a constant throughout the runtime of the game

i don't know if it's even possible to change at runtime lmao

[wintry quarry]

fixedDeltaTime is indeed changeable but if you don't change it it's a constant

[brazen pagoda]

Exactly - and in deterministic-requiring games, differences in intermediate timings may cause differences in pathing or movement changes or physics collisions. The butterfly effect may increase the minor discrepancy into a big one

So for starters, a fixed step game doesn't use float for time

[wintry quarry]

it's still a fixed-timestep simulation. The wall-clock time at which FixedUpdate runs in real life isn't material to that

[naive pawn]

if you use fixedupdate for those, all of them will be running at the same rate

you might get issues if you mix fixedupdate with update for stuff that should be in "lockstep"

but that would just be a mistake

[brazen pagoda]

Let me just re-iterate that in a fully deterministic system, even the fact that time is measured as a float would cause issues.

A "lockstep" should use a fixed long interval

[wintry quarry]

Float is deterministic on the same hardware

[brazen pagoda]

^ And that is not always the same hardware

[naive pawn]

float has a spec

im pretty sure it's deterministic always

[brazen pagoda]

As mentioned, online RTS games is where the Lockstep process comes from

[naive pawn]

if it's implemented to spec, at least

[wintry quarry]

not really because different hardware uses different numbers of bits internally for floating point math

They still abide by IEEE 754

[naive pawn]

shouldn't the result be the same, if it's following the same spec?

[wintry quarry]

no because you end up with different amounts of error based on the precision. The spec doesn't dictate how many bits of precision to use in the floating point math module

[brazen pagoda]

There's something correct for both here. But that's because of efforts that .Net has put into it. But either way - the problem is a real one. And even if a float is to spec - the developer still has to operate correctly around that and use that float correctly.

OP is asking questions about a real problem with real research and I think it's incorrect to dismiss that if they want to learn.

[naive pawn]

is that the same "precision" mentioned as part of a format in the spec?

[brazen pagoda]

Just because "most games" or "singleplayer games" often don't need to care, that is not a good reason to dismiss it as "there's no problem here"

[raw smelt]

@brazen pagoda I think you undrestand my problem have you any sugetsion ? Make game frame fixed ? so i will count time by frame or something ? (i am new at game develpoing XD )

[naive pawn]

Make game frame fixed
no

[brazen pagoda]

All of the RTS games in the 90s had to deal with this problem. And there's tons of research into it.
The separation between a simulation loop and a rendering loop was to solve a problem with speed between hardware and different segments of code - not to solve determinism.

[naive pawn]

cool, not old enough to have experienced that

[wintry quarry]

this just isn't possible

Making game frame time fixed only works when you have complete control over the hardware on which the game will run

That's how OG arcade games in the 80s worked

[raw smelt]

Why are you so "NO " XD
I know that SC2 if someone PC is too slow game actually give you information that is "slow down" (for everone) becouse of that And in game time is slower

[naive pawn]

@raw smelt i think you should revisit this

your actual game won't have any issues relevant to this

if you're curious to learn in chexxor's direction, then separate that from your game

[wintry quarry]

Yes Unity supports this out of the box with the "Maximum Allowed Timestep" setting in the project settigs -> time page

[naive pawn]

you've already been told numerous times why a fixed frame rate doesn't work lmao

[raw smelt]

OCh i will check that

[raw smelt]

Why not ? you just mesure in game time by number of frame that all

and you will achive 1 secend and 1 in game secend if you have 60 fps

if you have only 50fps just game slowdown

[raw smelt]

Yep but you still don't understand XD

[naive pawn]

i do

[raw smelt]

i thinkg about fix a max fps

and then calculate everything per fps

[naive pawn]

you're thinking about a static deltaTime

and there's already a static deltaTime

it's called fixedDeltaTime

you're just making the experience worse for not much gain

[raw smelt]

Only if game can't run at 60fps

[naive pawn]

good lord

exactly

that is my point

if the game can't run at 60 fps, you make the experience worse
instead of just... simulating at 60Hz and then showing it at 30 fps

[raw smelt]

if i paly game and for some reason i get like 5 fps becouse some update (not in game )
i hate when game just teleport me and i am dead becouse i see like 5 screen shoot and have no controll and enamy did hit me 10 tiems and i didn't see that

[naive pawn]

are you going to make a game that's so unperformant that it's 5fps though

there are easier ways to solve that

[raw smelt]

Chirs i can give you fps numer and attack speed
So i will lose for example 20dps even with 100fps XD and

[naive pawn]

i give up

[raw smelt]

becouse i will miss 1:5 frame

[naive pawn]

that just isn't an issue with a fixed time step

realistically you don't have to get that specific

you're worrying about a problem that hasn't presented itself yet

get your game actually working first before worrying about the details chexxor mentioned

realistically fixedupdate might not be perfect but it's way easier and will work fine for now

[raw smelt]

bad numbers XD

[polar acorn]

You know, the best way to explain to them why this is a terrible idea is to just let them do it

Have fun. Knock yourself out kiddo

[neon forum]

for the c# language if I modify an array within a foreach loop, does the array not actually remember the modifications after the loop completes?

[raw smelt]

I probably made i wrong example XD OK i will go and thinkg about that
(but i am sure that there is non cosistency I just feel it in MATH XD )

[wintry quarry]

arrays remember modifications regardless of whether loops are present or not

note that you can't modify the array by modifying a foreach iteration variable though

you can't modify the foreach iteration variable at all

unless you mean it's a class and you're changing some field in it

but that's not modifying the array itself

modifying the array would be something like myArray[someIndex] = someNewValue;

otherwise you aren't modifying the array

[neon forum]

That's what I thought, yeah.

Main issue I'm experiencing is that I DO modify the array correctly, but seemingly it shifts back into it's previous state post-completion of the foreachloop

[wintry quarry]

Show the code

otherwise we're just speaking in vagueries

because it's not clear what you mean by "modifying the array" here

[naive pawn]

frame 1
  timeSinceLastShot += 25 (now 25)
  timeSinceLastShot = 25 -> don't shoot
frame 2
  timeSinceLastShot += 25 (now 50)
  timeSinceLastShot = 50 -> shoot once
  timeSinceLastShot -= 40 (now 10)
frame 3
  timeSinceLastShot += 25 (now 35)
  timeSinceLastShot = 35 -> don't shoot
frame 4

  timeSinceLastShot -= 40 (now 20)
frame 5
  timeSinceLastShot += 25 (now 45)
  timeSinceLastShot = 45 -> shoot once
  timeSinceLastShot -= 40 (now 5)
```you just counted wrong

[wintry quarry]

there are all kinds of pitfalls with value types vs reference types for example that could be tripping you up

[brazen pagoda]

First of all - I just want to voice that - if you just want to make your game, as the others said, this topic does pause your progression on that game - if you want to understand how this works, then looking at history and existing research is great. I spent some time making games in C++ by coding pixels into DirectX and building systems from scratch on that. I learnt a ton from doing so. But I didn't produce games very fast compared to what I can do in Unity by just using the existing features.

---

You might have a concern with the number of bullets fired over a time interval. And I wanna address that first.

A typical way of doing a cooldown system of a TD game is like the following:

public class ShootingTower
{
    public float CooldownMaxTime;

    private float _currentCooldown;

    private void Update()
    {
        _currentCooldown -= Time.deltaTime; // Or fixedDeltaTime or whichever time step you want to use

        if(_currentCooldown <= 0)
            Shoot();
    }

    private void Shoot()
    {
        // Spawn projectile and send it at an enemy

        _currentCooldown = CooldownMaxTime;
    }
}

The problem here that would cause you to loose DPS is that shooting resets the cooldown completely.
A better solution is to keep track of how much extra time has passed. I.e. "how far below 0" is the cooldown right now.
This is quite simple as you can just modify the Shoot method as follows

_currentCooldown += CooldownMaxTime;

This way, if there was extra time that will now contribute towards the next bullet being fired sooner since the new cooldown will include the negative value from before and the new value would thus start at something that's smaller than the Max Cooldown. An unlucky frame time won't delay the next bullet unless you have a really low frame counter.

Main issue is that I do check for tileTypes that aren't 1(that means they're modified) during the insertion into the array of the foreach loop.

But somehow they all default to 1 when it hits the loading section

am I screwing up the values and refernce types?

[wintry quarry]

Well first off it's not clear what type tileHolder is

[neon forum]

ah, right, let me add the class code for that

[raw smelt]

Yep i was thinking about "remeber Extra time too " THX BTW
(:
And CHris THX too
I like to make many question (sometimes seems unrelated)
But i often try make some implication from new information than just ask if i remeber information correctly
(Becouse if i try make implication i can be more sure if i understand corretly the new iformation becouse if I do then implication will be correct )

[neon forum]

https://paste.mod.gg/ydlrhgefiafq/0

added tileHolder class code as well as the stringToTile method

[wintry quarry]

anyway can you explain what this code is suppsoed to do (seems like you're manually parsing JSON? 😬 ) and what's going wrong exactly

[neon forum]

I manually parsed JSON and that part works

[wintry quarry]

I still don't see what tileHolder is

[neon forum]

ah

That's a 2d array of TileStorages

it's x and y are always equal to the size of the grid on gamestart

[wintry quarry]

ok so what's going wrong with this exactly?

[naive pawn]

just keep this in mind for the future #💻┃code-beginner message
if you're learning about theoreticals, don't make your project rely too heavily on you learning that
gotta make a game before making a good game

[neon forum]

Oddly enough, when I run the game, export a map json, and then load it during the same instance, everything is fine.

When I close the game and reopen it, then load the file, the array seemingly forgets the modified tiles post foreach loop

and I do not know why

it literally says in the debug.log that it HAS them, but then when I go to the add tile section, it forgets them

[wintry quarry]

i don't have enough context about your game to know what a modified tile is or what it would mean to "forget" them or "have" them

sounds lioke probably a bug in your saving and loading logic somewhere? Most likely in the saving logic

[raw smelt]

Now i make "game" only for learning xd . I AM 100% sure that after making Basic mechanics i will just remove project and start again (spaghetti code nad practic etc )

[neon forum]

It's not because it can save/load perfectly while the game is running, it's when I close it and reopen it where the 2d array seemingly ignores the objects inserted into it

[wintry quarry]

because it can save/load perfectly while the game is running

Or maybe it's not actually doing that

and it's just correct in memory

Anyway a scary part of all of this is the manual JSON parsing/manipulation stuff

all kinds of things could be going wrong there

[wintry quarry]

I think you just need to debug your code. Find where the discrepancy is being introduced

veriufy the data is being written corectly to the file,
verify it's there in the loaded string,
verify it's being parsed correctly

[neon forum]

I already did that

[wintry quarry]

verify the x/y and all the rest are being parsed correctly

if you did you would have found where the discrepancy is being introduced

[neon forum]

I can show you my debug.Logs that literally even after the insertion mod foreach loop the array shows that it has been updated

okay, for the sake of not making 1 billion lines, I will create a if statement that checks to see if the tile is modified(if the tileType != 1, post the log),
I will also debug.log the fixit string, which is the string that is parsed by my stringToTile, as well as the result of stringToTile's parsing before it is converted into a tileStorage object.

Hello.
I'm trying to do a top down movement in 3D in Unity, and my player got a rotation where it looked. I have only the 8 directions.
The problem is when I walk diagonally, the player is looking in the right direction, but when I release the keys sometimes the player realign in one of the other two directions when they should stay facing the diagonal.
I imagine that I'm not releasing the keys at the same frame and therefore I have something like (0, 1) at the last frame.
How can I fix this?
I'm not sure what this problem is called, so I didn't find much on Google.

        Vector3 movement = new Vector3(moveInput.x, 0, moveInput.y);
        
        // Movement
        rb.linearVelocity = movement * moveSpeed;
        
        // Change rotation of the player
        if (movement != Vector3.zero)
            transform.rotation = Quaternion.LookRotation(movement);```

[brazen pagoda]

I think your theory is accurate on the release timings.

The first idea that comes to mind is to not do the rotation instantly. Maybe do a "rotation-over-time" approach, this way if you release both keys quickly it won't have time to do the full rotation to the 90-degree angles.

Another approach could be to add a delay - say rotations only happens 0.1s after a key change, but gets ignored if both keys are released by then.

Normally I would see a variation of this problem when an analogue stick was released and when it almost reached 0 I would get some odd inaccuracy behaviours. The solution then was to increase the deadzone (Input Settings) of the stick or the threshold of when to ignore stick input (Code). (Instead of Vectro3.zero, check if the ABS input is greated than 0.0001f)

I use a event system in the sample scene and in the main menu. when i turn it off its inpossible to click the start game button. So why cant i have 2 event systems? Or can I have 1 event system for every scene and how do i do taht

[wintry quarry]

You can only have one because having two wouldn't make sense and would end up double triggering all UI events

If you're additively loading scenes you could either not include one in the additive scene or use a singleton pattern for it to ensure there's only one at a time

[errant shore]

ooooooooooooooooh

thank you very much

but i need to inlcude one

[rocky canyon]

yes u do..

id keep 1 with some type of master scene.. or in ur DDOL (dontdestroyonload)

[errant shore]

waittttt i made a mistake

[rocky canyon]

i have a GameCanvas

i always have.. none of my other canvas' have an eventsystem

they'll all work off that 1

[errant shore]

niceeeee, I had a event system in the sample scene and it was completely useless

so now it works

[rocky canyon]

samplescene is completely useless

there i fixed that for ya

lol

[errant shore]

where do you guys upload your finished games? so friends or other people can just download and play or something like that

[rocky canyon]

http://itch.io is a common one

[errant shore]

whoa thank you

[rocky canyon]

on itch u can post both executeables (installed games)
and webGL (games played in the browser)

[errant shore]

oh thats good but I need a tutorial for exporting, ill search on yt

exporting from unity

yo there are coool games

[errant shore]

guys my head is exploding,I ve done something and now they load both at once

[cosmic quail]

Steam is the best if you want to make money

[errant shore]

[pure pike]

So I have a script so when I press and hold a certain button, a thing activates, but how would I make it toggle so I press it once it pops up, then press it again to close it

[rich adder]

`bool myToggle

if(Input.GetKeyDown(MyKey)) {
myToggle = !myToggle;`

[pure pike]

Ok I'll figure something out

[errant shore]

guys please , i have only the main menu scene in the build settings, why does it load the level

[rich adder]

the level ?

what is "the level"

[errant shore]

level scene

so i have 2 scenes main menu and level, mainmenu is in buildsettings, but both get loaded

[whole osprey]

Are you accidentally calling whatever you do when you press play at some other time?

[rich adder]

how do you know both get loaded

Hi. I just started trying to integrate my MySQL database into my game on Unity 2022.3.53f1. I understood the dangers of connecting a database directly to the game, but I decided to do it anyway, to test. I took a look at the MySQL Connector, and saw that each version was compatible with a version of Unity's .NET. However, I don't know which .NET version my Unity has, as it no longer appears. How will I know which version of the MySQL Connector is compatible?

I didn't see .NET Standard in the list of MySQL Connector versions.

[errant shore]

Because of this #💻┃code-beginner message This is Menu and Game Mixed

[rich adder]

.NET standard is 4.x without a few things

[rich adder]

Do you have code to switch scenes? show that

[edgy radish]

So any MySQL Connector compatible with 4.x versions should work?

[rich adder]

if the dll was made for standard use that, most of the time though you will be using the .NET Framework which is just full on 4.x

.NET Framework can add a bit of "bloat" but gives you more compatibility

here's the main differences explained
https://docs.unity3d.com/Manual/dotnet-profile-support.html

[edgy radish]

thx, I'll test it

[edgy radish]

I placed MySql.Data.dll in the Plugins folder, and the following error occurred:

Unable to resolve reference 'Google.Protobuf'. Is the assembly missing or incompatible with the current platform?
Reference validation can be disabled in the Plugin Inspector.
Unable to resolve reference 'ZstdSharp'. Is the assembly missing or incompatible with the current platform?

Do I download whatever he asks for on Google?

I left Unity on .NET Framework, and downloaded MySQL Connector 9.2.0.

According to the manual, I think it should work, or do I have to download those DLLs, right?

https://dev.mysql.com/doc/connector-net/en/connector-net-versions.html

[rich adder]

if that targets .NET 9. it wont work

[edgy radish]

Oh, then version 8.0.20 should work. I'll test it.

[rich adder]

there is also this
https://github.com/Hanslen/Unity-with-MYSQL
the dll is probably already compiled for unity
another option
https://github.com/Uncle-Uee/mysql-unity

or use SQLite

though I would not use MYSQL locally at all. No point

[edgy radish]

I tested it and it gave the same error about missing DLLs that it gave in the newer version. The difference is that this one came with the missing DLLs, so I could install them. I just don't know if it will work.

If it still doesn't work, I'll try all of your options. Thanks.

[rich adder]

https://github.com/Hanslen/Unity-with-MYSQL
this one has a perfectly working DLL

unlike SQLite which can be portable, this would not even run on anyone who doesnt have sql server

Made this simple c# Scrip where. Player Looks at the Target's position and Moves towards it when you press Forward..
it is a Simple script. i'm just learning and did this as a practice...

using UnityEngine;

public class LookRotation : MonoBehaviour
{
    public GameObject target;
    public float lookSpeed = 2f;
    public float moveSpeed = 5f;


    void Update()
    {
        FollowAndLookAtTarget(); // Call the method to follow and look at the target
    }





    void FollowAndLookAtTarget()
    {
        // Get the target position
        Vector3 targetPosition = target.transform.position;
        // Get the target position in the world space
        float moveVertical = Input.GetAxis("Vertical");
        // check if Target is attached 
        if (target != null)
        {
            Vector3 moveDirection = (targetPosition - transform.position).normalized; // Normalize to prevent faster diagonal movement
            transform.position += moveDirection * moveVertical * moveSpeed * Time.deltaTime; // Move the Player

        }


        //  Get the Gameobject to LOOK AT Target object
        Vector3 lookAt = new Vector3(targetPosition.x, targetPosition.y, targetPosition.z); // Get the target position
        transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.LookRotation(lookAt), Time.deltaTime * lookSpeed); // Smoothly rotate towards the target direction
    }
}

[keen owl]

Looks AI generated but what’s the question exactly?

[rich adder]

sorry but this is not very good

also https://unity.huh.how/lerp/wrong-lerp

[molten cipher]

it's not but thanks

[molten cipher]

why is the Slerp wrong? i want the gameobject's Z axis to smothlo tilt towards the Target position.. i'm a beginner

[rich adder]

aside from the slerp being wrong (read the page I linked you )
so, moving transform.position is essentially teleporting and it completely ignores walls

[molten cipher]

i'm reading

[rich adder]

but yeah lerp is least of the problems, so normally you want to move a rigidbody or character controller directly

[molten cipher]

i just made this code based on what i know ( i don't know much) started coding 4 days ago

haven't gone to Character Controller part yet. i'm practicing on cubes and spheres

[rich adder]

mhm and now you learned a few new things

[molten cipher]

tbh i didn't it's too complicated to me.. like Wrong-Lerp? it says that it is it's own thing... i don't like to rush things . i only want to learn step by step and make sure to understand what i'm doing.. my goal there was to Make the cube's Z (forward) Value to rotate towards the Target's Position..

it does do that

i'll get better eventually

[rich adder]

I'm just pointing out what was wrong, but its very unlikely anyone is at all going to use this

lerp is the least part that is wrong

[molten cipher]

i never said to use it.. i said " you can do this and that" as in, it is possible...

oh nvm i did say that

lol

my fault

[rich adder]

this is a null ref waiting to happen

 Vector3 targetPosition = target.transform.position;
        // Get the target position in the world space
        float moveVertical = Input.GetAxis("Vertical");
        // check if Target is attached 
        if (target != null)
        {```

do you know why?

the last line is hint towards what's wrong

[molten cipher]

target position is a tarrget Gameobject's position data.
float is a data -1 or 1 based on Vector3(data, 0, 0

and

if target is not null

then should the following code happen

meaning if the Target is assigned

don't see any errors here

[rich adder]

look careful.

in order to access the position vector3 data as you said, where are you accessing that

its just an order issue mainly.

[molten cipher]

Vector3 targetPosition = target.transform.position;

here

[rich adder]

yes that comes from the component transform

but on target

do you see where i'm going ?

if target is ever not assign aka null, what do you think its going to happen

[rich adder]

this has nothing to do with what I said lol

[molten cipher]

oh you mean it'll freeze in one space

meaning it's direction will be 0

that's what you're saying?

[rich adder]

no

you are accessing transform component from a target gameobject

if you don't have target assigned, aka its NULL. How would access a transform component on a Null object ?

[molten cipher]

if ( Target is not Null) then the code will happen...

if it's null

it won't

[rich adder]

where do you have that?

[molten cipher]

in the Void function

which then goes to Update

[rich adder]

I am aware, I can see it

you're not understanding
that one is unrelated to the line i pointed at

[molten cipher]

well you're not saying what the issue is so. how can i understand it.. idk what you mean

[rich adder]

I was trying to see your knowledge of basic code execution and object references

[molten cipher]

i don't have it dude i just started

[rich adder]

well perhaps start with the basics of c#

[molten cipher]

i started with basis from Learn.Unity.com

first steps and ongoing.

and tried to make a script based on my knowledge

[rich adder]

its good site but you still need to check individual c# basics

[rich adder]

okay which way does code run

[molten cipher]

up to down.

[rich adder]

okay good

so given that order, what do you think its going to happen here on this line
Vector3 targetPosition = target.transform.position; if target is not assigned

your null check is where?

before or after?

[molten cipher]

are you saying that it should be inside of the if statement?..

[rich adder]

if you want to test it go ahead, remove the reference(in the inspector) from the target field see what happens

[molten cipher]

sec

so i had to place everything inside of the if statement and it has no issues now, with or without target attached.

understood ! thank you

[rich adder]

yup mainly anything that has target reference, moveVertical never needs to be in if statement, but it can if you want to

[molten cipher]

thank you, will note that.

[native widget]

Does unity expose any information for the last time the player did a full click (mousedown, mouseup)?
I want to do something when the player did a click, followed by a mousedown+drag

I want to do something when the player did click-drag

[sour fulcrum]

i don't believe so but it should be pretty easy to manage yourself

[native widget]

Seems like it, I just made all my images to hold the time they were last clicked

[sour fulcrum]

do the images need to know that?

whatever is managing your input stuff can probably right?

[raw smelt]

Is there any implementet function for finding (k) biggest elements ? k<< n

var closestGameObjects = gameObjects
            .OrderBy(go => (go.transform.position - origin).sqrMagnitude)
            .Take(5)
            .ToList();

that pard of code have O(n) or O(nlogn ) ?

[earnest wind]

is this the way one should copy the values of a script to another script?

or is there a better way only to copy the public variables

[eternal needle]

dont crosspost #📖┃code-of-conduct

[eternal needle]

you shouldnt really need to do this in many cases, but id probably just make a method and pass everything needed at once

[earnest wind]

i need everything, really, just didnt want to make the photo big

i guess it would be okay for the manual work?

since if i would do some tricks by copying it might not make new lists, but just make pointers

[eternal needle]

this code is going to be a nightmare to manage in the future, and i say you shouldnt need it cause this indicates really bad design. either way if this is the route youve taken, there isnt a way that avoids having to declare each of these lines somewhere.

[slender nymph]

whatever this component is, also seems like it is doing way too much

[earnest wind]

its just copying

[slender nymph]

i meant the component being copied

[earnest wind]

i mean yeah it is doing a lot

it holds all the data for the component

[eternal needle]

it seems to hold literally everything lol

[earnest wind]

yep

[eternal needle]

color, rigidbody, shader details, lights??, input

[earnest wind]

yeah

[slender nymph]

and "the component" has too many responsibilities and should realistically be broken up into several. and if this is some sort of data storage object, why not just copy it with the MemberwiseClone method which makes a shallow copy of the object (which this seems to be sort of doing)

[earnest wind]

cant break down

no need to anyways

[eternal needle]

you 100% can, you just dont want to

theres also no need to do it the way you are currently doing it

[earnest wind]

i dont need to, its easier if its all in 1

[slender nymph]

it's also objectively worse if it is all in 1

you're creating a nightmare to debug

[eternal needle]

might as well make your entire game in one file too

[earnest wind]

then how can i do it? idk what memberwiseClone is

[earnest wind]

bet

[earnest wind]

i dont need to debug, this is for my own inspector system

[eternal needle]

🤷‍♂️ all youve shown is a bunch of lines assigning a field to another field. I dont know what you actually intend to do with this in the first place. Maybe take a step back and see what problem you're actually solving here

[earnest wind]

it doesnt have icons yet sadly but i will do that later

[slender nymph]

i don't need to debug
until you run into a bug . . .
do you not know what debugging is?

[earnest wind]

i know what it is, but i know what is wrong with my code if there is something wrong lol

[slender nymph]

sure, jan

[earnest wind]

[earnest wind]

jan?

wat

[eternal needle]

could you possibly be anymore vague? i think i got too much information out of this. Seriously, take some time and actually think about what you're doing here. how am i supposed to say anything based off this message and the code above

[earnest wind]

😭 man what else can i say, i just wanted to know if it would be possible to copy, i searched on google but it was using some very weird ways, and it wouldnt work with values like Lists, since it would just point but not actually create new ones

[slender nymph]

what you are currently doing does not create new lists either

[eternal needle]

Supposedly they wouldve known about that bug already
#💻┃code-beginner message

[earnest wind]

it does, i just couldnt screenshot the whole thing, its way bigger than 1 screen 😭

[earnest wind]

there is no bugs about the code

i just wanted to know if there are ways to copy

[lean steppe]

Anyone know how to swap layers in runtime?? Ite giving me this issue here

[slender nymph]

https://screenshot.help

[lean steppe]

? My photos r pretty clear lol I don’t see the issue

[lean steppe]

Also I’m aware it’s not the range nor nonexistent layer issue I think. I grabbed value of a layer assigned in the inspector, so that should be valid. The only issue here is it’s attempting to add a layer to the GameObject, not changing it. Any idea on how I could change the layer instead of attempting adding to it ??

[eternal needle]

the issue is people dont want to read code in that format, and also its just better if you learn to take a screenshot properly. !code

hey have i problem that i feel the solution i srelatively simple i just dont understand how to fix it exactly

so basically i am trying to make a 2d top down game.. but my character controller doesnt work

(i copied it form this one minute video)

thx 4 explaining

[fast relic]

it's Rigidbody2D not RigidBody2D

[slender nymph]

then you need to save your code again because you don't have RigidBody2D aywhere in that snippet you posted

[woeful locust]

see

thank you

i knew it was relatively simple

[verbal pollen]

Does anybody know why physics isn't working for unity dots, when I create a sphere, and I place a rigidbody it doesn't fall

did you save the file?

[lean steppe]

Wait no not channel. Whatever the chat thing is called

[woeful locust]

yep

[slender nymph]

yes, that is a channel. it's just a forum channel. and dots is a relatively large topic and is quite different from the typical gameobject workflow so it makes sense for it to have its own channel

[woeful locust]

wait

[lean steppe]

Does ur GameObject ur attaching the script to have a Rigidbody then?

[woeful locust]

ok

its fixed

[eternal needle]

if you really did, then maybe just a rare bug where unity didnt pick up the changes and didnt recompile

ive had that happen once a blue moon

[woeful locust]

probably

i made a space adn then saved

and it worked

[lean steppe]

Ohhh
It looked different than this so I was kinda confused lol

[slender nymph]

that is not relevant to the error they showed. what they showed was a compile error which means the code was wrong somewhere

The number references upfront of the variable is very annoying how to disable it it reduces the beauty of my script..😅

[timber tide]

You don't know what you got until it's gone

[hollow quest]

maybe if codebase was 1 million lines sure

[lean steppe]

Anyway. Anyone know how to do Additive Blending? I’m pretty much nearly clueless about Shaders lol I was wondering if Unity has a preset one or something…

[sweet lantern]

I think Shader Graph has a blending node. Could be wrong, but by default, Unity only uses Multiply for blend modes. Some years ago, I tried generating functions that would essentially reverse engineer the effect you want before doing Multiply and it was not pretty. 😦

[timber tide]

Some of Unity shaders provide it, otherwise shader graph it

The particle shader I know for sure has options for it

Oh wait, lit already provides additive

[sweet lantern]

When you say "references" you mean the various keywords and attributes? Things like [SerializeField], private, float, etc.? Cuz those all do important things and are pretty necessary for defining behaviour. If you mean the line numbers, those help you when the compiler throws an error so you can know exactly which line the problem is on.

Imagine you have 1000 lines of code and the compile says, "There's an error somewhere." Now, you have to search through 1000 lines and check each one just to try and see where the problem is, let alone what it is. Versus if it just said, "Null Ref on Line 42," then you know something specifically on Line 42 is null. Much easier.

The numbers can also help inform you of when your class is getting too big and it might be time to refactor and split things off. If it starts going above 500, that might be a good time to consider that your script could be doing more than it should.

[celest ridge]

I was thinking that when I see some of the old tutorials they write code and they don't have this refrences resulting there code is look preetier and I also want to disable that but now I realised that is not annoying that is usefull..

Hey I'm writing some of my first scripts in the game I want to create a script for player movement where I can go forward backward with keys and rotate around with mouse but confused what to do while I'm using rigidbody's add force fucntion I hold the key force adding on it continuesly.. and having abnormal behavior if I use linearvelocity function it oppose all the other velocities applying on the object for transform.position it going beyond the wall and penetrate the wall.. what should I took approach..

[cloud walrus]

I'm having some weird unexpected behaviour, i can't modify Y Axis in real-time it's like that i could modify it but i only see the change when i'm in game mode and even when i'm in game mode i can't change it, watch the video to understand

What i'm trying to fix is to make it modifiable in real-time where i see the changes immediately

[rich adder]

show code

[slender nymph]

you need to use something like OnValidate to do that

[cloud walrus]

this is my code btw

public class Level2Position : MonoBehaviour
{
    [SerializeField] GameObject theObject;
    [SerializeField] GameObject minPosition;
    [SerializeField] GameObject maxPosition;
    [SerializeField] float yAxis;
    [SerializeField] float zAxis;
    void Start()
    {
        Vector3 midPoint = GetMidPoint();
        theObject.transform.position = new Vector3(midPoint.x, midPoint.y * yAxis, midPoint.z * zAxis);
    }

    void Update()
    {
        
    }
    Vector3 GetMidPoint()
    {
        return (maxPosition.transform.position + minPosition.transform.position) / 2;
    }
}

[cloud walrus]

i shared it above

[slender nymph]

you also only ever use the value of that variable inside of Start which runs a single time in the object's lifetime (during runtime)

but yeah you could put that offset pos logic in OnValidate

[cloud walrus]

so i need a new method called OnValidate so the changes happens in real-time? that's it?

[rich adder]

OnValidate is a unity method

https://docs.unity3d.com/6000.0/Documentation/ScriptReference/MonoBehaviour.OnValidate.html

in a nutshell it runs when you update value in the inspector

[cloud walrus]

thx a lot guys I appreciate your help!

[cloud walrus]

Thanks guys! it's totally working fine now! @rich adder @slender nymph

public class Level2Position : MonoBehaviour

I'm a begginer in unity for some reason when i type debug on script editor it doesn't show me the complete word how can i fix that i looked up a lot of tutorials and didn't find a solution

Hi, i been wondering, how i can make a character/enemy do specific kind of movements in a 2D plataform setting. I mean, like a boss or smt

cuz for example i want my enemies that when the player is too near of them, to jump upward and fordward (right or left). or another enemy that when spots the player it jumps towards it. The thing is, how i manage to do so?

i tried using the pushforce but i feel like is too "unstable" for the job

[eternal needle]

if you want an exact movement, you'll probably just have to manually declare this in code. its hard to exactly help without knowing whats wrong with your addForce. you can definitely get an object to go up and down using unity physics

[acoustic belfry]

i mean, i feel like addForce is too unexact, i want them to move in a more elegant? way, like more... strict way

Like some enemies in Hollow Knight, or some bosses from Ultrakill like Gabriel or Minos (to wich despite being in 3D it represents what i want to do in 2D)

[eternal needle]

i havent played either of those games

[acoustic belfry]

oh...

well, what i mean is like, enemy is in place A, it moves to a place B inside it own area

[eternal needle]

that still just sounds like moving an object. im not sure how those games handle it but you could temporarily stop using the rb and directly affect its position if you need it to move to a position no matter what. animation curves can help if you want to make some equation for example if it needs to move faster at the start

Hey guys, I am trying to get the arm to point to the location of the mouse, and it works as intended except for when the mouse position gets too close to the arm. When it gets too close, the arm rapidly rotates up and down.

Link to a video showing the issue here: https://youtu.be/9aqUBjuiTs4

The arm sprite uses a custom pivot point at the edge of the arm.
Code for the rotation of the arm and the gun here:

Transform parentTransform = this.transform.parent.GetComponent<Transform>();
var lookDirection = Input.mousePosition - Camera.main.WorldToScreenPoint(transform.position);
float angle = Mathf.Atan2(lookDirection.y, lookDirection.x) * Mathf.Rad2Deg;
transform.rotation = Quaternion.AngleAxis(angle, Vector3.forward);
parentTransform.rotation = Quaternion.AngleAxis(angle-90, Vector3.forward);

The gun is a child of the arm, so parentTransform refers to the arm.

Pretty new to Unity/game dev so thanks in advance! And ignore my bad placeholder art haha.

[hexed nymph]

Yooo I want a animated button but the animator component does not work

I clicked on the "auto generate animation" and doesn't work either

does anyone knows how to solve this?

I also have the update mode in Normal

I did the animation in Adobe Animate

[pulsar creek]

private void TriggerExplosion(Vector3 explosionCenter)
    {
        GameObject explosionInstance = Instantiate(explosionPrefab, explosionCenter, Quaternion.identity);
        
        GameObject[] players = GameObject.FindGameObjectsWithTag("Player");
        GameObject[] enemies = GameObject.FindGameObjectsWithTag("Enemy");

        
        GameObject[] enemiesAndPlayers = new GameObject[players.Length + enemies.Length];
        players.CopyTo(enemiesAndPlayers, 0);
        enemies.CopyTo(enemiesAndPlayers, players.Length);
        List<Life> lifeInRange = new List<Life>();

        
        foreach (GameObject obj in enemiesAndPlayers)
        {
            Life targetLife = obj.GetComponent<Life>();
            
            Rigidbody targetRb = obj.GetComponent<Rigidbody>();

            
            if (targetRb != null)
            {
                
                Vector3 directionToTarget = obj.transform.position - explosionCenter;

                
                float distance = directionToTarget.magnitude;

                
                if (distance <= explosionRadius)
                {
                    lifeInRange.Add(targetLife);

                    
                    directionToTarget.Normalize();

                    
                    targetRb.AddForce(directionToTarget * explosionForce, ForceMode.Impulse);
                }
            }
            DealDamageToLife(lifeInRange);
        }
    }
void DealDamageToLife(List<Life> lifeList)
    {
        foreach (Life life in lifeList)
        {
            if (life != null)
            {
                life.LoseLife(damage);
            }
            else
            {
                Debug.Log("Life is null");
            }
        }
    }```

Is there a reason why I'm always getting Life is null logged? I'm certain I have a LifeManagerEnemy method in every enemy, which inherits from Life.

Nevermind, I think I figured it out

The life component wasn't in the object I'm checking, but in its child

[naive pawn]

you should probably not be using Find with Tag like that each time an explosion is triggered. why not use an overlapsphere check to get only the ones in the explosion radius?

[shy pollen]

so... quaternion * vector3 isnt working for me.. im trying to rotate a vector3, and i swear i've done this before this way.... :/

[pulsar creek]

If I recall correctly, it should be the opposite, no? vector3 * quaternion

[shy pollen]

neither way works :/

[pulsar creek]

Can I see the code?

Like, just that part?

[shy pollen]

flipping the quat & vector3 wont compile either

i swear it should be working, something with unity 6?

[pulsar creek]

It might not be this, but try capitalizing Quaternion

[shy pollen]

oh wow...

[pulsar creek]

I'm rotating objects just like that, and for me it works in Unity 6

[shy pollen]

yeah that was it..

and its quat * vector3

Thanks unity for that near invisible tripwire 🫠

[hexed nymph]

Yooo I want a animated button but the animator component does not work
I clicked on the "auto generate animation" and doesn't work either
does anyone knows how to solve this?
I also have the update mode in Normal

Idk if this helps but the animation isn't just scaling the button or moving it, its another sprite

I created the anim in Adobe Animate and but it in the game as a animation with a controller but for some reason the button does not animate

[stark burrow]

If movement is updated in fixedupdate and camera in update in fps. Does it mean that movement can have different delay based on fixedupdate timer and player could move to different angle compared to camera rotation

can anyone help me out how to use smartphone camera as real time video streaming to unity

[subtle osprey]

how would i modify an achievement so that it changes the popup depending on the level

like my game runs off a game manager and the achievement conditions are stored there

[rocky canyon]

well wouldnt u just check the level w/ the gamemanager and change it

[vagrant wolf]

I have a variable for sideway when i put it on the addforce it doesn't work but if i put a number it works

[rocky canyon]

its probably not enough force then

[red igloo]

I'm using cinemachine for my fps controller, How can I make it so when I look around the player rotates with it and I want to move in the direction I am looking in. I already have my player movement setup I'm just a bit confused how to set the cinemachine script wise.

https://paste.ofcode.org/8nNdQcSTFUi8BTemTA6WMs

[rocky canyon]

well. since ur camera is already moving.. u can just use the cam's directions multiplied w/ ur input

if(w)-> movePlayer with cam.transform.forward * input;
if (a)-> movePlayer with -cam.transform.right * input; etc

[red igloo]

Thanks I will try it 👍

[rocky canyon]

        Vector3 moveDirection = (cameraTransform.forward * vertical + cameraTransform.right * horizontal).normalized;``` something like this

        characterController.Move(moveDirection * moveSpeed * Time.deltaTime);

[red igloo]

Thanks that worked great!

[noble cedar]

is there anyone willing to check my code and help me also teach me how to optimize correctly my scripts in unity like what to do or what not to do I have self learnt unity. I am asking this because sometimes when I am testing my game in editor it just freezes idk if I somehow made infinite loop or just my PC isnt strong enough for rendering it sometimes

[red igloo]

How would I control the mouse sensitivity? Is there a setting in cinemachine 3?

[rocky canyon]

how is it set up? are u controlling the cam w/ code?

[naive pawn]

fyi this is just a c# thing, casing matters

well, same in most if not all programming languages

[rocky canyon]

big red squigly != tripwire

[brazen pagoda]

At least you get big red squigly - unlike Python that will pretend everything's fine, and send you on a 3-hour journey to find out why stuff don't work

[noble cedar]

every single database be like

[naive pawn]

with python you get a yellow squiggly instead

[noble cedar]

VS code shows errors 😄

[rich adder]

my guess is your credentials are still not setup correctly. I don't use mysql like this, I've mainly used it with XAAMP , so I'm not sure there .
My suggestion would be using like SQLite makes everything simpler.

[vagrant wolf]

i feel like c++ is easier than python no?

[rich adder]

hell yea

python stinks

[umbral rock]

so i have a movement script here with a character controller and i would like to be able to jump, how can i implement this with a character controller? or do i need a rigidbody to do it?

[rich adder]

subjective

[vagrant wolf]

nah Luau

[rich adder]

math heavy people like functional programming (haskell, clojure, lisp) or like pythony ones

arguably C# is one of the easiest langs

[tight inlet]

Imo python is just english with extra steps

But c# is quite beginner friendly as well

[lean steppe]

nvm wrong chanel

[ashen wind]

I'm making a mobile game and when I play the build on my phone, the physics feel fine, but on my friend's phone it seems like the player is accelerating way too fast

I'm guessing it's a lag thing

my physics code is this:

            if (rb.velocity.y < 10)
            {

                rb.AddForce(new Vector3(0, gs.upwards_thrust, 0), mode: ForceMode.Force);

I know that sometimes lag issues are normalized by multiplying by time.deltatime, so I also tried this

rb.AddForce(new Vector3(0, gs.upwards_thrust * Time.deltaTime, 0), mode: ForceMode.Force);```

but it didn't seem to make any difference

[wintry quarry]

Not enough context here

We need to know if this is happening in Update or FixedUpdate

AddForce should only go in FixedUpdate generally

[ashen wind]

update

got it

[wintry quarry]

Yeah that's your problem

[ashen wind]

i'll try that first

[wintry quarry]

And get rid of deltaTime

[ashen wind]

is there anything that as a rule shouldn't go in fixedupdate?

[wintry quarry]

Input handling

[ashen wind]

but the force is only added when the player gives input

so isn't this input handling?

[wintry quarry]

Yes

It's fine if it's like GetButton or GetAxis

Not ok if it's GetbuttonDown or GetKeyDoen

In general the ideal approach is to handle the input in Update and the physics in FixedUpdate

You would communicate between the two with variables

But for this simple case it's ok to read the input in FixedUpdate as long as it's not a GetKeyDown situation for example

[ashen wind]

if (Input.GetKey(KeyCode.Space) || Input.GetMouseButton(0) || Input.touchCount > 0)```

so what you're saying is this would be fine to put in fixedupdate

[wintry quarry]

That will work fine

[ashen wind]

thanks so much

[formal valley]

hi how can I spawn the white circle in random position but not in at a specific height from floor and platforms.

[wintry quarry]

but not in at a specific height from floor and platforms
Can you... try to rephrase this more clearly?

[formal valley]

ok wait

[rich adder]

do you mean like not spawning it inside the platforms?

[formal valley]

yeah and not in the air that the player can't reach it.

[rich adder]

hmm probably some type of while loop then do some Casts to check if its blocked, for height you can take into account the Player jump height / max reach (need a bit of maths) and keep the iteration until you find suitable place (throw a max iterations for not endlessly finding)

[naive pawn]

you could randomize only the x position and then if it's in the platform area, displace it upwards

[rich adder]

yea that could be simpler actually

[naive pawn]

or randomize the x position but y above everything, and then raycast down to displace it downwards appropriately

though both of those solutions wouldn't let it spawn in the space under the platform

[formal valley]

can I do it here or do I need to write new script and make Tag.

thx

[polar acorn]

Do what here

[naive pawn]

you can't randomize the position when you're waiting for a detection, no

[formal valley]

no I mean when he take the coin
it will disappear and it will teleport to other position.

[formal valley]

@polar acorn

[polar acorn]

I'm not sure how that code and that question are related

[formal valley]

I'm so bad at explanation sorry.

[umbral rock]

i dont understand, i am working with a character collider and whenever i stand still on the ground he doesnt say he is on the ground and when i start moving then he says im on the ground, how is this possible?

i wanna implement a jumping system so i can only jump when my character controller is on the ground

and now i can only jump while my character is moving lol

[rich adder]

are you calling .Move every update ?

[polar acorn]

The usual culprits:
A) Calling move more than once per update
B) Setting the vertical velocity to 0 when grounded instead of a small downward value

[rich adder]

isGrounded only works while .Move is called iirc

[umbral rock]

yes its in the update method

[umbral rock]

i add a velocity of -1 so it stays on the ground

[naive pawn]

sure then

[umbral rock]

is it bad to call the move more then once in the update method?

[cosmic quail]

no

[rich adder]

yes

combine your Move call into 1 operation

[polar acorn]

Yes. You should modify a vector throughout update and call move one time at the end

Grounded gets set only when _the previous _ move call hits ground
