Is this how movement in a game is supposed to work? | Official Unity Discord | Page 1

modern isle Jan 31, 2026, 1:08 PM

#

I found this while developing my game, the character doesn't seem to go straight?Im getting confused on that

#

This is the code, but there doesnt seem to be anything weid in it ⁨⁨⁨⁨⁨```cs
Vector2 Direction = MovementV2.ReadValue<Vector2>();
Rigidbody Rigidbody = Character.GetComponent<Rigidbody>();

Vector3 Z = Direction.x * Character.transform.right;
Vector3 X = Direction.y * Character.transform.forward;

Vector3 ForceDirection = (Z + X) * MovementSpeed + Physics.gravity;

Rigidbody.linearVelocity = ForceDirection;```⁩⁩⁩⁩⁩

#

maybe adding the Z+X causes this?

#

Question:Is that how a character moves(im confused 😭 )?

#

modern isle I found this while developing my game, the character doesn't seem to go straight...

Is your crosshair actually centered?

#

Also the gravity part doesnt seem right

#

But thats unrelated

#

Unless your gravity has non-zero X or Z values

modern isle Jan 31, 2026, 3:07 PM

#

versed field Is your crosshair actually centered?

I think it is, let me check

modern isle Jan 31, 2026, 3:08 PM

#

versed field Also the gravity part doesnt seem right

How else could I add gravity ?The script that adds gravity is at the top

modern isle Jan 31, 2026, 3:24 PM

#

versed field Is your crosshair actually centered?

yeah it looks centered

#

its pivoted in the middle of the screen

#

I realized that the character goes a bit to the left

#

How do I fix that now?

could be lots of things.

Your input might include a little horizontal.
Your camera might be slightly rotated relative the the character object

how could the input be horizontal tho?Its just wasd

Lots of reasons, the simplest being maybe you have a gamepad plugged in you forgot about.

HAve you ever heard of Debug.Log?

#

This is what Debug.Log was made for

#

We don't need to waste any much time thinking of theoreticals about why, we can just directly check if it's the case and then move on if it isn't

Ok debug prints that it goes a little to the right

#

Is this because im doing Z+X?

pliant cliff Jan 31, 2026, 4:35 PM

#

modern isle Ok debug prints that it goes a little to the right

what did you print specifically?

modern isle Jan 31, 2026, 4:35 PM

#

pliant cliff what did you print specifically?

The direction in which the player is moving

pliant cliff Jan 31, 2026, 4:35 PM

#

which is what

#

ForceDirection?

#

or Direction?

#

I'm talking code specifics here

modern isle Jan 31, 2026, 4:35 PM

#

The direction I apply to a force

#

movement speed

pliant cliff Jan 31, 2026, 4:36 PM

#

you should print both of those variables separately

#

ForceDirection and Direction

#

and label them

#

and let us know what you see

modern isle Jan 31, 2026, 4:37 PM

#

pliant cliff and let us know what you see

ok so when I debug ⁨Direction⁩ it doesnt show error when I print ⁨ForceDirection⁩ it shows that it goes a little to the right

#

This is because im doing X+Z I think

pliant cliff Jan 31, 2026, 4:38 PM

can you show the actual code you wrote

#

and the console window with the logs

modern isle Jan 31, 2026, 4:39 PM

#

Direction

#

#

⁨```Vector2 Direction = MovementV2.ReadValue<Vector2>();
Rigidbody Rigidbody = Character.GetComponent<Rigidbody>();

Vector3 Z = Direction.x * Character.transform.right;
Vector3 X = Direction.y * Character.transform.forward;

Vector3 ForceDirection = (Z + X) * MovementSpeed + Physics.gravity;

Debug.Log(Direction);

Rigidbody.linearVelocity = ForceDirection;```⁩

#

code

pliant cliff Jan 31, 2026, 4:40 PM

#

this is pretty inefficient. Just do this:

Debug.Log($"Direction: {Direction}, ForceDirection: {ForceDirection}, Forward: {Character.transform.forward}, Right: {Character.transform.right}");```

#

it will save us a lot of time going back and forth

modern isle Jan 31, 2026, 4:41 PM

thanks that cool , I didnt know debug could do this

pliant cliff Jan 31, 2026, 4:41 PM

#

(this is what i meant by labels)

pliant cliff Jan 31, 2026, 4:41 PM

#

modern isle thanks that cool , I didnt know debug could do this

Debug.Log just prints any string you give it

#

it's nothing to do with debug.log really

#

this is just how to make nice strings in C#

#

string log = $"Direction: {Direction}, ForceDirection: {ForceDirection}, Forward: {Character.transform.forward}, Right: {Character.transform.right}";
Debug.Log(log);```

modern isle Jan 31, 2026, 4:42 PM

#

Do I send the results as an image or as a video

pliant cliff Jan 31, 2026, 4:42 PM

#

modern isle

ok so - the last part of the log is showing us pretty clearly your character is just rotated slightly

modern isle Jan 31, 2026, 4:42 PM

#

I only moved forward

pliant cliff Jan 31, 2026, 4:42 PM

#

your character starts out rotated

#

can you show how your character object is set up

#

the hierarchy of it, adn the inspectors for each object in it?

#

I suspect your camera is just rotated slightly or something

modern isle Jan 31, 2026, 4:43 PM

#

#

I think it is because I was looking around with the character while walking

pliant cliff Jan 31, 2026, 4:44 PM

#

ok now go down the line - ViewModelPivot, CameraPivot, and Main Camera

#

are any of those rotated?

#

also how does your camera rotation work? Which object is it rotating?

modern isle Jan 31, 2026, 4:44 PM

#

pliant cliff are any of those rotated?

They arent rotated

#

I did make a bridge to test it better

#

and it goes to the right

#

let me test something

pliant cliff Jan 31, 2026, 4:45 PM

#

#

Let's see the code for these two scripts

modern isle Jan 31, 2026, 4:47 PM

#

pliant cliff

I removed the side movement and I got this

#

the forward movement it bad I think

modern isle Jan 31, 2026, 4:47 PM

#

pliant cliff

right now

pliant cliff Jan 31, 2026, 4:47 PM

#

modern isle the forward movement it bad I think

yes I understand that - can you show the code of the scripts?

modern isle Jan 31, 2026, 4:48 PM

i already read it

you can share the other script

Although there is a bug here

            XAngle = XAngle + Axis.y * TurningSpeed * Time.deltaTime;
            YAngle = YAngle + Axis.x * TurningSpeed * Time.deltaTime;```

#

Time.deltaTime should not be here

#

and you should reduce TurningSpeed

pliant cliff Time.deltaTime should not be here

But its a update?

pliant cliff Jan 31, 2026, 4:50 PM

#

modern isle Its slow tho

after you remove Time.deltaTime it will feel very fast

#

so you will need to reduce turningspeed

pliant cliff Jan 31, 2026, 4:50 PM

modern isle But its a update?

mouse delta is already framerate independent

it shouldn't be multiplied by deltaTime

modern isle Jan 31, 2026, 4:51 PM

pliant cliff mouse delta is already framerate independent

A thanks

pliant cliff Jan 31, 2026, 4:51 PM

it's already "how much did the mouse move this frame"

modern isle Jan 31, 2026, 4:51 PM

#

pliant cliff it's already "how much did the mouse move *this frame*"

I understood how delta time works now

pliant cliff Jan 31, 2026, 4:51 PM

#

ok honestly the code is looking good to me so I'm not sure other than if you could finish showing me the inspeoctors of those obejcts I asked about above

(the gravity thing is definitely still wrong but that's a separate issue)

pliant cliff Jan 31, 2026, 4:53 PM

wait

is this a second copy of the camera rotation script?

That could be the issue

modern isle Jan 31, 2026, 4:53 PM

The bottom script?

#

This is the main camera

pliant cliff Jan 31, 2026, 4:54 PM

#

It seems like you have a copy of the "CameraRotation" script on both of these objects:
Character
and
CameraPivot

#

it should only be on Character I think

modern isle Jan 31, 2026, 4:54 PM

#

I DO

#

I HAVE A COPY

pliant cliff Jan 31, 2026, 4:54 PM

see if removing the second one changes anything

modern isle Jan 31, 2026, 4:55 PM

I think I got another bug

#

I cant turn now

pliant cliff Jan 31, 2026, 4:57 PM

modern isle I cant turn now

Increase the TurnSpeed in the inspector

#

(for the remaining camera rotation script)

modern isle Jan 31, 2026, 4:57 PM

#

pliant cliff Increase the TurnSpeed in the inspector

no its not that, the screen glitched and it doesnt turn

Look

I tried to turn right

its from this script

}

#

Could it be because YAngle is being updated every second?

#

Tho why arent the arms rotating with the character tho

pliant cliff Jan 31, 2026, 5:00 PM

#

one sec lemme review this stuff

#

You might also want to lock the y rotation of your Rigidbody here:

#

we don't want the physics engine rotating fighting with us

#

Since we're manually rotating in our script

modern isle Jan 31, 2026, 5:02 PM

#

pliant cliff You might also want to lock the y rotation of your Rigidbody here:

the y rotation too?

pliant cliff Jan 31, 2026, 5:02 PM

#

yes

modern isle Jan 31, 2026, 5:03 PM

#

Ok so the thing is weird now

#

When I rotate the mouse the character rotates

#

but the arms and camera dont

#

even tho they are parented to the character

#

pliant cliff Jan 31, 2026, 5:04 PM

#

the only reason that would happen is:

Some other script setting their rotation (such as the second copy of the camera rotation script)
If they have separate Rigidbodies

#

oh wait

#

I think I see the problem

#

I do see the problem

modern isle Jan 31, 2026, 5:06 PM

#

pliant cliff the only reason that would happen is: - Some other script setting their rotation...

If none of those are true(I deleted the second camera rotation script and Only the character has a rigid body) then im kind of meh

pliant cliff Jan 31, 2026, 5:06 PM

#

This is the problem:

            ModelPivot.transform.rotation = Quaternion.Euler(-XAngle, 0, 0);
            Model.transform.rotation = Quaternion.Euler(0, YAngle, 0);```

#

Specifically this:

            ModelPivot.transform.rotation = Quaternion.Euler(-XAngle, 0, 0);

modern isle Jan 31, 2026, 5:07 PM

#

pliant cliff This is the problem: ```cs ModelPivot.transform.rotation = Quaternio...

I doubted that part too

pliant cliff Jan 31, 2026, 5:07 PM

#

It needs to be this:

ModelPivot.transform.localRotation = Quaternion.Euler(-XAngle, 0, 0);```

#

rotation -> localRotation

modern isle Jan 31, 2026, 5:07 PM

#

I didnt know localRotation existed

#

makes a lot of sense

modern isle Jan 31, 2026, 5:08 PM

#

pliant cliff It needs to be this: ```cs ModelPivot.transform.localRotation = Quaternion.Euler...

It works now thanks

#

Tho you said the gravity was a problem?

pliant cliff Jan 31, 2026, 5:09 PM

#

the way you're doing gravity is a slight problem yeah

modern isle Jan 31, 2026, 5:09 PM

#

Could you explain why?

modern isle Jan 31, 2026, 5:09 PM

#

pliant cliff the way you're doing gravity is a slight problem yeah

If I remove it, the character wont fall

#

How could I do it better?

pliant cliff Jan 31, 2026, 5:09 PM

#

Correct, you need to fix it, not remove it

pliant cliff Jan 31, 2026, 5:10 PM

#

modern isle If I remove it, the character wont fall

Do you notice right now when the player falls, they aren't falling naturally? They are instantly going to full speed and not accelerating ever right?

modern isle Jan 31, 2026, 5:10 PM

#

I do notice the character going up slopes is slower than walking

#

the gravity does feel too slow

pliant cliff Jan 31, 2026, 5:11 PM

#

you should really do this:

    ```cs

if (Character != null)
{
Vector2 Direction = MovementV2.ReadValue<Vector2>();
Rigidbody Rigidbody = Character.GetComponent<Rigidbody>();
float yVel = Rigidbody.linearVelocity.y;

        Vector3 Z = Direction.x * Character.transform.right;
        Vector3 X = Direction.y * Character.transform.forward;

        Vector3 ForceDirection = (Z + X) * MovementSpeed;
        ForceDirection.y = yVel;

        Debug.Log($"Direction: {Direction}, ForceDirection: {ForceDirection}, Forward: {Character.transform.forward}, Right: {Character.transform.right}");

        Rigidbody.linearVelocity = ForceDirection;

    }```

modern isle Jan 31, 2026, 5:13 PM

#

pliant cliff you should really do this: ```cs if (Character != null) { ...

Gravity feels better now thanks

#

And the character can walk up stairs faster

pliant cliff Jan 31, 2026, 5:14 PM

#

yeah you were just instantly setting their y velocity to -9.8 at all times no matter what before

#Is this how movement in a game is supposed to work?
