It's not even the Y axis

You want:

float xInput = Input.GetAxis("Mouse X") * mouseSensitivity;
rb.rotation *= Quaternion.Euler(0, xInput, 0);``` @twin bolt

#

wot

twin bolt
lunar grove
#

the value is stuck at -0.0200000 whenever the game starts, idk what's causing it tho

wintry quarry
#

what value

lunar grove
#

the Y value

wintry quarry
#

Of what

lunar grove
#

Y value of my player when the game starts, tho its presetted to 0 by default

wintry quarry
#

what is "the y value of my player"?

#

do you mean the player's position?

lunar grove
#

Oh yeah sorry

#

The Y value of my player's position is going to 0.02000 when the game starts

wintry quarry
#

well.. you have gravity: characterDirection += Vector3.down * characterGravity * Time.deltaTime ;

#

it's falling

lunar grove
#

i removed it and tried, however it seems that being on the box collider ground makes it like that

#

I use different types of main controllers with different scripts in my games so I'm worried that it'll bring in my main controller from the base scene into the game, instead of simply leaving it there in it's original position

#

Because the tutorial said that it brings the main controller into the next scene, and I don't want that to happen

Just added lines 25, 26, and the start function, but I'm getting this error, anyone know how to resolve it?

also where on earth did you come up with yield return new((float)0.2);

I'm sure it's a code issue, but can i ask why i dont see object sprite? I have object called Cursor (transform.position = Camera.main.ScreenToWorldPoint(Input.mousePosition). Also sorry for my English

It's position is working fine but sprite is gone

I have an enemy with a 2d rigidbody and boxcollider which I am moving in the Update function using rigidBody.velocity = movement; Movement is decided in a coroutine with this function

private IEnumerator ChooseDirection()
{
        chooseDirection = true;
        yield return new WaitForSeconds(4f);
        movement = new Vector2(Random.Range(-1f, 1f), Random.Range(-1f, 1f));
        chooseDirection = false;        
}

My wall collision does this to invert its movement and go away from the wall(I tried multiple things but couldn't find the right idea)

rigidBody.velocity = new Vector2(rigidBody.velocity.x * -1, rigidBody.velocity.y * -1);

The problem I have is that when it collides with a wall (also a boxcollider) it doesn't invert the velocity it had. I'm also facing the issue that the front of the enemy is not always facing the directions it's going which I assume can be fixed by changing its rotation instead of the velocity I do right now. But how would I invert its rotation when it hits a wall then?

thick sentinel
thick sentinel
wintry quarry
#

do you want to invert or reflect?

#

inverting would just be -

#

but in OnCollisionEnter, the velocity has already changed from the collision

potent coral
#

inverting, if its moving NW it should go SE

wintry quarry
#

then rb.velocity = -movement; no?

Ok, new problem. I'm trying to make code that updates the sprite of a gameObject every time my timer reaches a certain value. The problem is, the sprite updates every frame rather than once.

swingTimer += Time.deltaTime;
if (swingTimer >= .50)
{
    swingTimer = 0;
}
else if (swingTimer >= .30)
{
    currentFrame++;
}
else if (swingTimer >= .20)
{
    currentFrame++;
}
else if (swingTimer > .10)
{
    currentFrame++;
}
spriterenderer.sprite = spriteArray[currentFrame]

I've tried using Mathf.approximately(), but the problem with that is, given a lower framerate, it is possible that the timer never reaches said approximate value. How do I code this so that the sprite only updates once per comparison, but still insures that the sprite won't be skipped?

Animator Controllers - Unity Learn

An Animator Controller is a Unity asset that controls the logic of an animated GameObject. Within the Animator Controller there are States and Sub-State Machines that are linked together via Transitions. States are the representation of animation clips in the Animator. Transitions direct the flow of an animation from one State to another. In thi...

oh ok thx

so really you'd need to also do movement *= -1;

#

i.e.

    private void OnCollisionEnter2D(Collision2D collision)
    {
        if (collision.gameObject.CompareTag("Wall")) {          
            //rigidBody.velocity = new Vector2(rigidBody.velocity.x * -1, rigidBody.velocity.y * -1);
            movement *= -1;
            rigidBody.velocity = movement;            
        }
    }```

Is there any better way to do this?

RaycastHit2D hitLeft = Physics2D.BoxCast(PlayerDB.coll.bounds.center, PlayerDB.coll.bounds.size, 0f, Vector2.left, .1f, PlayerDB.spikesLayer);

RaycastHit2D hitRight = Physics2D.BoxCast(PlayerDB.coll.bounds.center, PlayerDB.coll.bounds.size, 0f, Vector2.right, .1f, PlayerDB.spikesLayer);

RaycastHit2D hitUp = Physics2D.BoxCast(PlayerDB.coll.bounds.center, PlayerDB.coll.bounds.size, 0f, Vector2.up, .1f, PlayerDB.spikesLayer);

RaycastHit2D hitDown = Physics2D.BoxCast(PlayerDB.coll.bounds.center, PlayerDB.coll.bounds.size, 0f, Vector2.down, .1f, PlayerDB.spikesLayer);

if (hitLeft.collider != null || hitRight.collider != null || hitUp.collider != null || hitDown.collider != null)
{

I'm trying to move objects using cursor, but something is wrong and joint is weak and working wrong (i'm working wrong i know)

here is the code:


public class Cursor : MonoBehaviour

        Vector2 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
        transform.position = mousePosition;

        if (Input.GetMouseButtonDown(0))
        {
            this.Activate();
        } 
        else if (Input.GetMouseButtonUp(0))
        {
            this.Disactivate();
        }
    }

    public void Activate()
    {
        RaycastHit2D hit = Physics2D.Raycast(Camera.main.ScreenToWorldPoint(Input.mousePosition), transform.forward);

        if (hit.collider && hit.collider.gameObject.GetComponent<Rigidbody2D>()) 
        {
            this.GetComponent<HingeJoint2D>().enabled = true;
            this.GetComponent<HingeJoint2D>().connectedBody = hit.collider.gameObject.GetComponent<RigidBody2D>();
        }
    }

    public void Disactivate()
    {
        this.GetComponent<HingeJoint2D>().connectedBody = null;
        this.GetComponent<HingeJoint2D>().enabled = false;
    }

#

So my game for some reason

#

After pressing on my retry button

#

On the next retry

#

the retry button gets triggered by Spacebar key

#

lol

#

I don't know if its because i was enabling and disabling scripts or not

#

Could it be that after clicking my UI button once, it becomes highlighted by the game and that's why I can press Spacebar to trigger it? Because after focusing on another window and then going back to the game, the problem disappears

short hazel
lunar grove
#

Is there a way to not give a button focus upon first clicking it?

#

becuz it also triggers another action in my script unintendedly lol

lunar grove
short hazel
#

Yes from the event system, using EventSystem.current.SetSelectedGameObject(null)

#

You'd call that inside the method that executes when the button is clicked

Hi, I have a projectile prefab with stats like bulletSpeed. During runtime, player can pick up powerups that can increase bulletSpeed but I don't want the change on the prefab to be kept after runtime. What can I do about it?

rich adder
weak rose
#

Okay thanks

buoyant knot
#

idk exactly how to fix your problem, but this script is too tightly coupled to your other code.

#

a script that controls movement should not have any references to player health, at all

#

also, you have a ton of magic numbers

#

like flatVel.magnitude > 400f

#

imo, for any movement script, you want to keep the update and fixed update loops as clean as possible

#

they will become absolutely massive

#

and make it a lot harder to fix anything

#

the majority of your fixed update loop contains information about collision for damage. none of that belongs here

#

you’ll find it’s a lot easier to find and fix problems once you separate all of this out

eternal needle
#

400 is also insanely fast, is your enemy a bullet?

buoyant knot
#

then your units are wrong

#

m/s = m/s * const. implies const is dimensionless. so if const depends on mass, you fucked up

swift crag
#

you're using AddForce wrongly

#

oh wait, no, I misread. That is fine.

#

I thought you were using it to apply force once

#

(like when you shoot a bullet)

#

This is applying a constant force to the projectile

#

If the projectile is heavy, then you'll need more newtons of force to accelerate it

buoyant knot
#

either way, he is taking a vector, making it magnitude 400, and assigning the x/z components to velocity

they don't collide I mean (talking about Debug ones)

I've been having issues with using 'LoadSceneAsync' and 'UnloadSceneAsync' for switching scenes

Either the code doesn't let me unload the scene or it completely resetsthe base scene, which I don't want

I'm not using Timescale for the end of the games either

So I'm not sure what's wrong

Ohh

swift crag
#

You're trying to call SetActiveScene too early, methinks

#

Even LoadScene doesn't actually load a scene until the end of the frame

soft canyon
#

I want to make a 3d dungeon generator, what's the best way to do it?

swift crag
#

so calling SetActiveScene immediately after LoadSceneAsync sounds way too early

fringe kindle
swift crag
#

You should wait for the scene to finish loading, then change the active scene

fringe kindle
#

Should it be done in a code linked to the new scene? When it's loaded in?

swift crag
#

You could listen to the completed event on the AsyncOperation that LoadSceneAsync returns

#

I guess you could also just do that in Awake in something in the new scene

#

Although I'm not confident about the exact order of things there

fringe kindle
#

Another thing is I tried to use the UnloadSceneAsync for when I wanted to exit the Jungle Game but it didn't work

#

It said something along the lines of "unloading the last loaded scene is not supported"

swift crag
#

that means you only have one scene loaded

delicate slate
#

i have ran into a prbolem can anybody tell me how to fix this?

Screenshot_244.png
swift crag
#

oh yeah, there's the thing I completely glossed over

#

just because you load a scene asynchronously doesn't mean you're loading it additively

#

That just means that you're allowing the game to keep running as Unity fetches stuff from disk

wintry quarry

a syntax error is when your code has an invalid structure

this is invalid syntax.

So i'm trying to make a draggable inventory system and am implementing the IPointer interfaces right now. Would it make more sense to put a script on each of the "slots" in my inventory to control the drag? or to put the script on the container of all the slots in the inventory

whatever is easier for you to get reference to the slot to move it or if you need to do additional logic

swap items around, combine stacks, etc

im currently beyond confused. my enemy starts by facing right and having a Y rotation of 0. and every time he turns it adds 180f to his rotY. meaning, in theory it should alternate between 0 and 180.

then i have the section where its

if(enemy.rotation.y > min value && enemy.rotation < max value)

but the things inside this if stay triggered even when the conditions arent met anymore and it should switch to else.

Am i doing something wrong?

Basic Third Person Character Controller in Unity - Unity C# Tutoria...

In this Unity tutorial, I teach you guys how to make a basic third person character controller in Unity using the C# programming language. This character controller allows you to jog (forward and back), sprint, and rotate around for basic player movement. I also show a few easy camera methods as well.

this still doesnt work as intended.
the Rotate part only works once and then never again. idk why bc i get te logs as intended

the enemy starts with a y rotation of 0, and once the rotate is triggered, it becomes -180, but by 0 + 180 i expect it to be positive.

I didn't worry about it because wan't that of a deal, but now it's just a pain to configure sprites

you should specify what you actually tried, and what did not work

Your question isnt specific enough then for what you actually need. There 100% are tutorials out there which will work for you. Your model should have literally 0 affect in this. Follow the tutorials more closely

You likely forgot to lock an axis, or your model is simply facing the wrong direction

You should definitely be using version control so you can separate out experiments and know what you did before.

But I'm thinking you may want to separate the floor and wall code. You could do perlin or something else for the floor code, but you'll want to build the walls around that result, not with the same algorithm I THINK.
Others will surely know more though, I have never done anything like that before

Hey, I'm using a FreeCam script I found on the asset store, my problem with it is that I would like to have multiple cameras that use this script and currently the script affects all cameras that use it.

So if I move with one camera, all other cameras with the script move with it, I'm not sure exactly why it happens. I would assume variables are shared between the instances, I'm quite new to Unity and C# (although I come from a Java background) so any explanation would be appriciated 😄

so then what do you think the result of GameObject.FindObjectOfType(<ColliderTypeHere>) is?

is it null?

that is not what i asked about

i see what you are saying

you said there is a collider in the scene. So will GameObject.FindObjectOfType(Collider) return null or not

yes

you are checking whether the object exists twice. first with the tag check. then you check if any collider exists in the scene for whatever reason

    }

    // Check if the LookAt target is null
    if (freeLookCamera.LookAt == null && playerTransform != null)
    {
        freeLookCamera.LookAt = playerTransform;
    }
}

}``` the camera works but does not follow the player when he walks. i feel like its coming from my player controller and its using the camera https://gdl.space/isagesized.cs

#

but i can confirm that the cam object is attached to the field

#

Could it be an order of execution?

Ok, making "Selecting Objects with Raycast" is way to complicated, I think I just put a 2 meter long small invisible cube in front of the camera and make a OnTrigger Event if it touches a interactable gameobject.

Any idea why this Selecting Objects with Raycast doesn't work or at least work only if you are close to it and look 90° to the right of the sphere?
It turns also blue if the player is not close enough what should not be cuased by the code because there is no lenght-raycast yet...

(Blue is standard color, yellow is highlighted color)

also you don't use the hasJumped variable anywhere

it is the coyoteTimer that is true, because of my if (isGrounded()){coyoteTimer = coyoteTime;hasJumped = false;}else{coyoteTimer -= Time.deltaTime;}

ionic lava

still not working

#

the issue does not occur with if (Input.GetButtonDown("Jump") && (isGrounded() /*|| coyoteTimer > 0) && !hasJumped*/))

this system works differently.. ur not actually rotating the sphere RB... ur setting the position of the graphics to the rigidbodies position.. and then you rotate the car.. the rigidbody just gets its direction from the car's facing direction.. the rigidbody just rolls (always facing the same direction) but rolling in the direction the car is facing its a roller ball with a car skin lol.. if u want to rotate the actual rigidbody you need a different setup. if u keep it how it is you can just turn on interpolation on the rigidbody.. it will smooth out the graphics a bit.

hi guys. i followed this unity documentation tutorial on how to make nav mesh agents work with root motion(by that i mean copy pasted) : https://docs.unity3d.com/550/Documentation/Manual/nav-CouplingAnimationAndNavigation.html
and my nav mesh agents movement has become extremely jittery.
at first i thought my animations were the cause of this but then i checked the values and, deltaPosition is the cause. this vector 2 is jittery also causes smoothDeltaPosition and velocity to become jittery. any idea why that is and how i can fix it?

https://hastebin.skyra.pw/ohohilexas.csharp -> SynchronizeAnimatorAndAgentRootM() function line 71

thanks!

apologies if this is the wrong channel. this is my first time trying to create anything in unity. i started with a 2D project.

i did the configuration of Visual Studio Code to Unity, did coding, attached the script to GameObjects, but whenever i run my build, it will start up on a blueish screen. it's supposed to show a black screen with white text.

i've tried making the main camera the same position as the canvas UI, i've tried changing the solidcolor to Black in the main camera, tried changing my render settings to several different things, tried setting the hierarchy in several different ways...

it's been two days of no progress due to me being unable to figure this out on my own...

please help?

#

The default mode, "Screen Space - Overlay" doesn't care where the camera is. The canvas is just rendered directly onto your screen.

oh, I missed the "build" part entirely

okay, so it is working fine in the editor.

Would save you a lot of time understanding things

That is a code related channel, if you have any issue with code you can ask here

#

Anyway, change your collision detection mode

rocky canyon
#

^ make ur detection continous

thick sentinel
#

ty

rocky canyon
#

could also probably beef up the colliders on the sides of hte screen (if that is indeed whats stopping them)

this is my code and i am traing to put an input field in there but it wont let me drag and drop it

so he could reduce it a bit

rare basin
vale cradle
#

i am new i don't know much

rare basin
#

and you make variable of the legacy input field type

vale cradle
#

sorry

rocky canyon
# vale cradle so he could reduce it a bit

i dont think his area has anything to do with it.. he doesnt have a designated area where the items can be clicked or moved.. he could program it that way.. so if the mouse position is off the side of a threshold stop it or drop the item..

#

but right now i think its b/c hes moving the rigidbody so fast it clips thru the colliders on the edge of the screen

#

raising the detection to continous will probably allow it to not pass thru

vale cradle
#

yes

#

Today i got to code different mouse clicks.. like if this is selected and u click it it will do somehing.. if u click and hold it will do something different.. if u click and drag it'll do yet something different 😄

otherwise he'll just copy&paste

lol, i said "i believe" if he's attempting to learn he'll still need to confirm

rare basin
#

most people would just copy paste it and if it will work then they dont need to confirm anything

rocky canyon
#

i just got here.. it can be my test..

#

if he returns ill know not to next time

#

lol

#

i may.. end up making my click script a statemachine..

#

so depending on wether its a click and release.. or a click and hold.. or w/e it'll transition into a state that returns different things..

an answer to my original question would be appreciated however

livid tundra
#

here's a stupid problem: I just want to rotate a sprite 90 degrees every using animation event triggers. I figured this would be a no-brainer since I already have triggers in other animations and I have a function to flip the another sprite.

Here is an image of my sword sprite, the animator with trigger events visible:

Capture1.PNG
#

And here's the code I thought would work (this script is attached to the Sword game object with the animator component)

Capture2.PNG
#

How did I mess this simple task up?

rare basin
#

you rotate it constantly to 0,0,90

#

you are not adding 90 on the Z

wintry quarry
#

They are adding 90 on the Z

#

Rotate is additive

livid tundra
rare basin
#

ok mb

wintry quarry
#

First step is add Debug.Log here and see if the code is running

#

also check the console window for any errors

#

A screenshot of the Animation Event configuration would be helpful too

rare basin
#

alternatively you could just do it without animation events

#

just rotate yourself and record the animation

wintry quarry
#

Well yeah the animation itself could rotate the sword rather than using events

rare basin
#

in events you could play a audio clip or something

#

but rotation through code in animation is kinda off for me

#

hit the record red button and just rotate it 90 degrees every X frames

livid tundra
#

I also correctly guessed that transform.rotation*=Quaternion.Euler(0,0,90) would work, but it's the same outcome

Unity's animator is breaking every time I change a script (doesn't matter which one) or really make any changes at all to the project. I am aware that I can close the Animator window and reopen it to temporarily solve the problem, but this is getting annoying. It happens eventually whenever I start a new Unity session too, so restarting Unity isn't a permanent fix.

NullReferenceException: Object reference not set to an instance of an object

Yeah... just a Uniy editor bug. Best you can do is report it, keep up to date, and hope they fix it

livid tundra

closing the Animator isn't preventing the problem anymore, it just shuts it up until I change something

#

ok

trail flare
#

every time I start the game I've made in there and I put my VR on, it just goes into computer mode instead of you being able to play the game you've made in VR

livid tundra
#

Know what, might be because one of my animations in the Animator doesn't have a transition for it to start yet

#

I'll get to that in a few min and see if that shuts it up

Ok so I want a power up to increase damage by a percentage , how would I go about changing that with every bullet fired?

Getting the bullet controller of currently fired bullet and adding to the damage each time I spawn the projectile

rich bluff

you should probably write system that allows projectiles and attacks to carry payloads of various effects

#

with damage calculated on hit

#

or not, i imagined you have various status effects based on what you said, but maybe the powerup is something simpler

rocky canyon
# frail star Good morning everyone , I have a general question to start with. My projectile s...

sounds good to me.. ur projectile (just like anything) should control the things relevant to it.. so the speed its moving, the damage it inflicts, etc..
interactions are when u can pass data. soo when the projectile hits something you can pass the damage thru that function to a health script for example.. and it can read the damage from the bullet.. and subtract it from itself, and so on

Can't add script component 'MatchMaker' because the script class cannot be found. Make sure that there are no compile errors and that the file name and class name match.

i get this error when trying to drag a script onto an empty object

So i have a beam overlapping onto 2 cubes at either end and i have to add a fixed joint where it meets. however the joint is only being attached to one of the cube, am i missing something?```void OnTriggerEnter(Collider other)

{

        Debug.Log("Hinge Attached");

        FixedJoint fixedJoint = rb.gameObject.AddComponent<FixedJoint>();
        fixedJoint.connectedBody = other.GetComponent<Rigidbody>();

        fixedJoint.anchor = transform.position + new Vector3(0, 5f, 0); 
        fixedJoint.connectedAnchor = other.transform.position;
