and the object can always access it aswell

cosmic dagger
#

Curious, why are you creating an instance of an SO (with ``Singleton.Create`)? You may as well use a C# object . . .

native seal
willow iron
#

can raycasts detect an item if the origin is inside that very item? for example, i place a empty transform inside a cube with a cube collider, and then point the raycast outside of the cube starting from the empty transform, would it detect the cube?

shell sorrel
#

so if it originated inside a collider and cast out, i do not think that is a hit.

#

but to be sure i would just make a test case, would not take more then 5 mins to setup and test

Is it possible to get data of an object dragged by player? I want to see if item which was dropped to inventory slot is the same as the item already placed in there. I use drag handling interfaces to drag it

native seal
#

you can use eventData.pointerDrag.GetComponent

Thank you

#

How do I do that in code…?

#

Like I think I understand

#

But I also just don’t

using UnityEngine;
using UnityEngine.SceneManagement;
using System.Collections;

public class GameMaster : MonoBehaviour
{
// Start is called once before the first execution of Update after the MonoBehaviour is created
void Start()
{

}

// Update is called once per frame
void Update()
{
    
} 

public void StartGame()
{
    SceneManager.LoadScene("HammerStaff");
}

}

Is it possible to make an enemy that literally have like barely any at and just runs straight at you?

teal viper
odd holly
#

Because every single tutorial I’ve found has had ‘Patrolling, Attacking, Wandering, fighting’ but I literally just want it to run at me and do contact damage

            ItemNumber itemNumber = item.GetComponent<ItemNumber>();
            Debug.Log(itemNumber);
            itemNumber.SetDestination(speed, nextBelt.targetlocation, this);```

so I have the above lines of code. Inside itemNumber i have the method SetDestination

``` public void SetDestination(float newspeed, Transform newtarget, Belt newcurrentBelt)
    {
        Debug.Log(newspeed+ " " + newtarget +" "+newcurrentBelt);
        currentBelt = newcurrentBelt;
        speed = newspeed;
        target = newtarget;
    }```

upon running the code this is what the console looks like (attached picture)

i just dont understand why everything seems to be working correctly except for the ItemNumber script
image.png
#

the errors claim that there is a "Object reference not set to an instance of an object" error when i call SetDestination, but it identifies itemNumber when i use debug.log

rough granite
#

where it should log the name of the object which im also 90% sure you didn't name object

#

oh wait nvm, i cant read 😭

#

can you provide more code?

That is a default asset reference, it can't load anything that exists in the scene, it needs to be an asset.

You probably don't even need to assign a default just assign it on the instance you're actually using

but would i need to make the transform of the player to public

eager spindle
#

You'll need a reference to the player's transform, yes. Whether you make it public is up to you, there's a few ways to do it.
Assuming you have a CameraController script attached to Player Camera, you can have a public Transform variable that will act as your camera's target. You can then set the camera's position to the targets position minus a number, like what you talked about earlier

Hi, How do you play a video then transition into a scene ?

ivory bobcat
#

What have you tried so far? There should be plenty of tutorials doing both.

tiny bloom
#

If I have a game object with rigidbody called rotator
inside there are children

I rotate rotator, but I want the children to hold their rotation
meaning they stay facing upwards while moving to accomodate the rotation of rotator
how to fix that?

#

world up or screen up

#

pretty sure if you're rotating on Z, everything would just rotate around and still be facing the screen

ruby python
#

If your objects are children, they will always follow the parent rotation unless you tell it specifically otherwise. Unless there's something I don't know. lol.

make sure you're not rotating on X

# ruby python Do you child objects have rigidbodies?

yea
so far i did this in child objects and it works, it's a bit glitchy so i think if i move it in update it will be better
but im not sure about performance xD

{
    transform.rotation = Quaternion.identity;
}
ruby python

#

Ah okay. Then yeah, move that line into Update. I don't think it will have a massive amount of a performance hit tbh.

And they may not need rigidbodies#

Depending on what they need to do.

#

@tiny bloom If you don't mind, could you show us what you are actually trying to do?

ruby python
#

Right okay, yeah they won't need a rigid body each iirc. The rigidbody of the parent object should govern their collisions.

night raptor
#

But they kind of do if they need to rotate in relation to the parent

this entire thing should probably just be part of the prefab

    var rb = rotator.AddComponent<Rigidbody2D>();
    rb.bodyType = RigidbodyType2D.Kinematic;
    rb.interpolation = RigidbodyInterpolation2D.Interpolate;
    _rotator.SetActive(false);

Hey guys, I'm trying to limit the rotation of a transform that is rotated on x-axis by world space and y-axis by self-space. When printing the eulerangles of the object, I'm only getting angles between 0-90 and 90-0 when exceeding 90°, while Z-Axis flips from 0 to 180. However I don't know why this happens and I can't read the actual value unity editor shows me of the object.

private void OnDivingState(ref Vector3 currentVelocity, float deltaTime)
{
    Vector3 inputVector = player.RawInputVector;
    float XInput = inputVector.x * _config.RotationSpeedX;
    float ZInput = inputVector.z * _config.RotationSpeedY;
    _transform.Rotate(0, XInput * deltaTime, 0, Space.World);
    _transform.Rotate(ZInput * deltaTime, 0, 0, Space.Self);
    Vector3 tempRotation = _transform.rotation.eulerAngles;
    // tempRotation.x = Mathf.Clamp(tempRotation.x, 0, _config.MaxDiveAngle);
    Debug.Log("Clamped Rotation X: " + tempRotation); 
    _transform.rotation = Quaternion.Euler(tempRotation);
}

#

Any idea how I can get the value from the inspector?
Referencing the transform by Transform _transform = Meshroot, while Meshroot is a public variable that's set in the inspector.

following:

  • Get the current pixel position on the Y axis (Green channel) from UV (-1 to 1)

disable the movement for the duration of that process. or switch entirely to working with forces

from a OOP perspective it only matters that the thing is above my class

thats like the whole idea of polymorphism

to not care what that thing is, just what behaviour it offers

interfaces perform a specific job which is why every interface you see is named IInterface

People already made it clear that its a naming convention and it exists for consistency.

you don't need the Generic "folder" since thats the one with IEnumerator<T> you don't need

eternal needle
# hardy wing Is somebody hurt? I just provided my point of view and was curious to hear if th...

Nobodies hurt, when you disregard something as "statistical evidence" which makes no sense in the context, its clear you didnt understand what people above were saying while actively putting out incorrect statements.
Its not a class which you were told above. Its an interface. people have mentioned it is for naming already. That is purely the reason
It doesnt affect how the program runs in the slightest

#

Sometimes people will even obfuscate their program and end up with random names like C17616

#

Naming only matters for us developers for consistency

hardy wing
#

Since we already agreed to drop the topic I will not respond but you just mispresented what happened, but it's okay. I can understand the consistency part at least but all good 👍

generics are funn

rough granite
#

Ahh i see (still lost 😭)

rich adder
#

GetComponent is a good example of a generic

#

You can put in any component in <T>

#

if you're doing a save system they are clean to save multiple different POCOs without making a method for each one

rough granite
#

Does c# understand what T is if i went and made my own type of GetComponent?

polar acorn
eternal needle
# rough granite Ahh i see (still lost 😭)

Its not that simple of a concept, to really understand how you would use generics you would need to go through a few examples.
GetComponent as nav said is a good example but you're on the side of using a generic system rather than implementing generics yourself

teal viper
polar acorn
#

public void GetComponent<T>() lets you use T which is provided when the user calls GetComponent<SpriteRenderer> or something

eternal needle
#

GetComponent essentially takes the type you give it, goes through the list of components and checks if that component is T

rich adder
#

List<T> etc. all have generic

#

pretty powerful stuff

my script seem to be behaving differently if i recompile it mid testing

#

why would that be?

zenith cypress
#

If you mean recompiling while in play mode, don't. Unity's version of a "hot reload" isn't really a hot reload and will just cause problems.

alpine temple
#

like this

#

the jittering is removed if i recompile the script

rich adder
#

The reason you're not getting spammed with other warning is because you only added a whitespace and thats probably ignored, still triggered compile action.

alpine temple
#

why is compile action removing the jitter?

rich adder
#

the usual culprits for jittering is Camera / Roation / Movement mismatch

alpine temple
#

after compiling its consistent 13

rich adder
#

looks like float imprecision somewhere, that doesnt mean the other isn't 13 (I see it often display as 12.97ish)

#

this is the strange behaviors you get when you compile while still running the sim

#

its possibly the first is running more parts of the code and causing a slight float imprecision

#

just a guess though

alpine temple
#

its flickering between 12.97 and 13.14

Hi o/ My brain isn't braining properly so I've once again have returned to you guys!
Right now I'M trying to create an Array of GameOJbects to populate the inside of an catalog (the gameobjects basically are the pages which i want to turn on/off, depending on the index of the current array).

I'm kind of struggling how to format that. My thought is to create a function that contains an index, depending on the which button is gettign pressed im exchanging the index with the current index. But I don't know how to write that in code, could someone point me my way?

#

Is it a simple for loop? foreach?

rich adder
fickle stump
#

Basically yeah, but how would i change the index? For loop? And how would i properly reduce the index aswell?

#

I plan on having a button that goes index++ and one index--

rich adder
rich adder
#

you can just check the array bounds, unless you want a "warp" behavior

fickle stump
#

Array bounds, havent heared of that yet

#

Will look it up!

#

Thank you!

rich adder
#

eg ```cs
public void NextPage()
{
if (currentIndex < pages.Length - 1)
{
currentIndex++;
ShowPage(currentIndex);
}
}

```cs
 public void PreviousPage()
    {
        if (currentIndex > 0)
        {
            currentIndex--;
            ShowPage(currentIndex);
        }
    }```

# eternal needle Its fine if you want to drop the topic but you stating we dont have to continue ...

Well, it's not that I want to. But the topic got unnecessarily heated which I blame mainly on myself and I didn't want any unnecessary drama in here. I came back after a long while so I don't wanna incinerate something instantly KEKW Regarding the discussion: my take on this was pretty much just that in my opinion and from what I took away from talks with people that are way more experienced than I am that it's more beneficial to look at type hierarchies in that exact mindset. It's a hierarchy. When I deal with an item, I only care about dealing with a returned value of type Item. I don't care how Item works. I don't care if it has implementations already. I only care about it being an Item that may or may not refer to types that override the behaviour. And people "always having named their classes like this" is not enough convincing material for me, that's all. And Java is an example of where people decided against that. I'm not saying I'm right or you are right. I'm just saying that not prefixing them convinces me more due to the reasons I provided.

naive pawn
#

hey real quick, i noticed there was kind of a gap in communication

#

you cited polymorphism as not caring about the interface - but that's about the runtime not caring about the specific implementation
the topic in focus was about you as a developer (and other devs, including your future self) being able to distinguish what a given type is for and how to work with it - that's what naming conventions are for

sour fulcrum
#

When you deal with an item you choose to care or not care about what it is

naming conventions provide information to support your decision, consistent naming conventions is just easy free built in info. do with it what you see fit

velvet moat
#

Is there a way in the editor to see which scripts use a specific tag?

rich adder
sour fulcrum
#

scripts don't use tags, instances of gameobjects do

rich adder
#

also how would you even know its a tag since they are so fragile
you can only search
.tag == "
or
.CompareTag("

#

do it better on yourself and start using components, tags are kinda trash

#

I wanna make a system where when my players ray cast touches the wall they can wall climb by alternating Q and E buttons to slightly increment their linear velocity Y but failing the combination would set it to 0, would a state machine be best for this

but you could if you already have one

# sharp mirage nah I dont

You dont really need a FSM to do what you listed , might make it easier seperating regular movement to the climing mechanic

#

FSM helps so you also don't have a shit tone of bools , and ontop of that multiple bools can be true that cause weird behaviors

#

Imagine if you had a bool "isClimbing" and "isRunning" , your whole character breaks if somewhere both become true somehow

sharp mirage
#

not home yet so I haven't actually implemented the system but I'd imagine the whole thing would just be a whole lot of embedded if statements

rich adder
sharp mirage
#

True

rich adder
#

I would honestly use a sepearte script so the feature can be disabled/enabled with ease and self contained

#

can go something like
ray with certain distance hits the wall, maybe do additional checks like if its a climbable one
player in that climbing state, do the rest from there with keys, if you jump off and ray isn't touching anymore you are in the other movement state

#

very similiar to how a ladder logic would work

sharp mirage
#

I thought u said I didn't need states unless that's just how u normally describe things anyways

I happen to have an issue with scene loading and awake/start order: scene A loads additively (sceneLoaded event fires), then awake and start for scene A fires. Then awake and start for scene B fires, THEN scene B loads additively (sceneLoaded event fires) ?????

I want to make sure all awakes are run before any start from any scene.

I'm using a scene group loader, that is, for each scene in the group, registering the async operation and setting its allowSceneActivation to false. then, after this loop, I wait in a while loop for all operations to reach progress of 0.9. After that, I set every allowSceneActivation to true. With my logging, I see that the allowSceneActivation activations are happening one after another, then scene A says it's loaded, fires awake AND start, then awake /start from scene B fires, then scene B says it's loaded ?

Is there any way to manage a bit better this order ?

#

after some more testing, looks like awakes run before the sceneLoaded event is fired, for any scene. That's fine, but I'd still want all starts to run only when ALL scenes are loaded. Is there any way to do that ? (without subscribing to sceneLoaded in all scripts or something)

nope, GetAxis is smoothly going from 1 to 0

ohhhhh

that makes a lot more sense, thank you

it's pretty annoying to be honest and it's better to handle this kind of smoothing by yourself. I almost never use GetAxis, only the raw version

i am using it, im using the .linearvelocity property

lemme try using it this time, it sbecause originally instead of transform.Translate(horizontal * speed, 0, 0); I had rb2d.linearVelocity = new Vector2(horizontal * speed, 0);

it has to

you are probably using the new input system and this code is using the old one

If you're fully intending the game to be played primarily through digital inputs, use Raw (or use the new input system that lets you define smoothing on a per binding basis)

have you copied this from a tutorial or are you writing this code yourself

# rich adder you should start by showing the code in question..

        {

What are some reason that a gameObject that has a ridgidbody and a capsule collider would slowly float into the air. But then if you change its mass to 50 it slowly goes back down to the ground.

the steps are
make a field for Coroutine
assign the field a value on StartCoroutine located in OnEnter
use trhe same variable in OnExit to StopCoroutine(myRoutine)

^ basically caching the coroutine when u start it.. (this specific coroutine)

and ur variable should be declared outside the methods.. (u want any method from inside the class to access it, for example some other method in the same class that could Stop it) so it would be a variable at the top of the class/ not inside (a) method
odd holly
#

wait no Im stupid

#

how do I make it stop after I stop colliding?

rocky canyon
odd holly
#

I forgot to tell it to stop...

rocky canyon
#

not sure how'd u go about that.. i just wanted to throw in my two cents on how to cache the coroutine reference

#

i dont believe there's a OnCollisionExit afaik that u could use to stop it..

#

but if u have the reference set up correctly its easy
StopCoroutine(coroutineReference); or attackRoutine
coroutineReference/attackRoutine being w/e u named the reference variable

odd holly
rocky canyon
#

yea, and i was told to "not confuse you"

#

it happens lol.. anyway now that u can cache a "specific" coroutine and know how to stop it.. i think ur doing pretty well so far 🍀 ¯_(ツ)_/¯

#

myself, i use Triggers alot.. so like a trigger a little bigger than the thing im colliding with

soo that way i can use OnTriggerEnter and OnTriggerExit to start and stop a coroutine for example

odd holly
#

you were pretty much right

#

its just OnCollisionExit instead of Enter

rocky canyon
#

not sure its suitable for ur use-case but i tend to have better luck with OnTriggerEnter and OnTriggerExit

says abunch of stuff like: usually indicates that an AnimationPlayableOutput object, which is responsible for direting animation data to a specific target (Like an ANimator) component has not been properley initialized or assigned..

#

typically occuring when a PlayableGraph is created or manipulated 👀 ya, idk what any of that means.. possibly #🏃┃animation would have a better answer

legacy animations cant be in a blueprint

if it is indeed related ot animation

can someone tell me why this code is not working it's working if i remove "* forwordInput/horizontalInput"

Because it reads input only once at the start. Those lines should be moved to Update

How do I rotate a gameobject into an absolute angle? I want the gameobject to point 40 degrees to the right, when my input on the x axis is positive and 40 degrees to the left, when x is negative. My current solution keeps adding the angle with each frame.

void Update() {
if (_moveInput.x > 0)
{
    _animatorPulseEngine.transform.Rotate(40,0,0, Space.World);
} else if(_moveInput.x < 0)
{
    _animatorPulseEngine.transform.Rotate(220,0,0, Space.World);
}
}
naive pawn
#

Rotate, well, rotates from the current rotation
you want to set the rotation, so rotation = ... or eulerAngles = ...

worn peak
#

I am sorry, but I don't quite understand how I am supposed to set the rotation

naive pawn
#

i just gave you examples

grand snow
#

Use Quaternion.Euler() and assign to transform.rotation

naive pawn
#

transform.rotation and transform.eulerAngles let you set the rotation
the former is a quaternion, the latter is a Vector3 of euler angles

worn peak
#

Ah so you meant it that way. I was confused, because I assumed rotation and eulerAngles like you said were meant to be values and not methods from transform.

grand snow
#

That doesn't make sense

#

Basically you should assign a new rotation to override it to what you want

#

Rotate() will manipulate the current rotation so won't do what you desire

worn peak
#

Like I said, I was just confused

I'm trying to make a character controller rn but i'm having an issue with jumping. It's inconsistent, every time I jump, the jump height is different and I don't understand why. Here's the code https://paste.ofcode.org/NVjv4ajrgNWYUWAL4X4xqf

keen dew
#

Don't multiply velocity by deltatime

waxen glacier
#

what should and shouldnt be multiplied by deltatime ?

naive pawn
#

it depends on the usage

#

if you have a value in x per second, and you want a value in x per frame, then you use deltaTime

#

if you aren't in that situation, you don't

#

that's what deltaTime is, a conversion factor - it's seconds per frame

waxen glacier
#

Ah ok, so multiplying the velocity by deltatime actually did the opposite of what I wanted right ?

naive pawn
#

you also shouldn't be using deltaTime on lookDirection if that's mouse input

waxen glacier
naive pawn
#

with the mouse thing, mouse delta is already in x per frame

#

your player.Move should have a * Time.deltaTime, because velocity is being treated as per second, but Move is taking a delta position per frame

waxen glacier
#

Dam alright thanks, removing deltatime just amplified every movement by 1000, i'll add some multipliers to reduce that

waxen glacier
#

like this ?

naive pawn
#

(and also you don't need the isGrounded check to apply gravity, you should do so regardless so the CharacterController stays in contact with the ground)

#

(also btw Mathf.Max exists)

waxen glacier
naive pawn
naive pawn
waxen glacier
# naive pawn (also btw `Mathf.Max` exists)

I use clamp instead because i had an issue where if i simply set the velocity.y to zero when grounded i wouldnt be able to jump, so i made the minimum 0 and the max any positive number

naive pawn
#

yes, that's what Mathf.Max would achieve

waxen glacier
naive pawn
#

you mightve been using Min before, which is an understandable mistake - it reads like "with a minimum value of x"
but it's kinda the opposite in this kind of usage, Max takes the larger number so it is applying a minimum value

waxen glacier
naive pawn
#

ah

waxen glacier
#

never used min either, i just used clamp cuz it seemed more intuitive to me

#

thanks you so much though the jumps are now consistent

#

So i guess i'll only apply deltatime to the actual move function instead of the values it uses

#

Time to make the little bean actually move

gray rivet
#

so im trying to make it so the player is only restricted to only one jump and i keep getting errors that i do not understand

image.png image.png
#

and also collisionInfo isnt working for some reason

rough granite

#

this is running off my little understanding so this makes sense

rough granite
north kiln
#

There will be more errors even if brackets are added to create the method scope, as you can't declare a public variable inside of a method

rough granite
gray rivet
#

alr lets start studying

naive pawn
rough granite

#

not to be a nuisance but im a little confused with problem 1

but mainly i just want to point out that == is a thing with strings.

rough granite

#

just collision

naive pawn
#

you can call it whatever

gray rivet
#

ok yeah thats what i though

#

its jsut ;

#

thats the problem

rough granite
#

the problem is what Chris said

gray rivet
#

so the lesson there is Methods dont have a ; to finish a line?

naive pawn
#

yeah, you don't need ; for everything

#

like i said above - just for field declarations and statements, and also with for

gray rivet
#

ok makes sense

rancid tinsel
#

any way to make it so that the sound plays when the TimerUpdate is a specific number, or is this entirely incorrect?

image.png
naive pawn
#

hover over the erroring code to see what it's trying to tell you

#

though, TimerUpdate can't be a specific number

rancid tinsel
#

wait nvm i get how to do it now

naive pawn
#

it's an Action

rancid tinsel
#

its an Action<int>

#

I have to wrap it like this basically

#

yeah i was intending to just mention the important part but yeah that's ambiguous to the standalone Action

how can i transfer some values from one scene to another? (without PlayerPrefs and similar things, i dont want to crap in the registry or savefile)

I thought I finally figured it out… I had it where GetComponent gets EnemyCombat… now it’s worse than before and literally NOTHING is happening

#

Honestly ts stopped being fun the second I started coding the enemies

grand snow
#

you lack core understanding of what a component is and how to get instances of components from other gameobjects to interact with them

#

as others said, following some learning courses will help you understand this but guess no time for that rn

odd holly

It would honestly be faster to just learn rn… if my computer wasn’t running the videos at 2 fps

maybe it cannot handle the unity editor and browser?

it takes me to the drop object function to the Rigidbody rb = grabbedObject.GetComponent<Rigidbody>(); line of code in it

rich adder

how do i fix it the grabbed object isnt staying in the holdpoint position when i click e tho

rich adder
#

make it not null by assigning a value

frail hawk
#

the first if statement is really weird

sweet pendant
#

wdym assign a value to it to the rb?

frail hawk
#

if Key / else

sweet pendant
#

whys it weird

rough granite
#

yeah i think you are dropping it the minute you pick it up which then sets the second if to be false

sweet pendant
#

oh

rough granite
#

cause GetKeyDown is only for one frame so the frame right after calls
else
{
DropObject();
}

sweet pendant

Making a game that involves placing tracks on a grid and I have UI buttons to switch between track type. Issue I am running into is that when I click a button it will place a track on the ground behind the button. The fix I am thinking of is affixing colliders to the camera in the button areas but is there a better way?

rich adder

do i turn them into links

thorn abyss
#

do i put all inside one all seperate them

rich adder
thorn abyss
#

the dialogue ui is not showing up. i know that the conversation works fine because i used debug logs. the problem is that i dont know why the variable is not set to true so it never shows up

mighty pilot
# rich adder show the setup

If you click green tile it places a track
I click the UI buttons on the top right to choose type
If a green tile is behind the button it will place a track when I attempt to switch
The white boxes are gonna have a collider so the mouse check hits them first

image.png
rich adder
mighty pilot
#

Correct

rich adder
#

otherwise you can try EventSystem.current.IsPointerOverGameObject()
or

    bool IsPointerOverUI(){
        PointerEventData pointerData = new PointerEventData(eventSystem){
            position = Input.mousePosition // Device.current.position.value -- for new input system
        };
        List<RaycastResult> results = new List<RaycastResult>();
        raycaster.Raycast(pointerData, results);
        return results.Count > 0;
    }``` 
which both essentially doing same thing using the Event System , which is what IPointer would use anyway

For some reason, if I move while jumping, my player character stays in the air for an unreasonably long amount of time and I have no idea how to fix it
here is my code

using UnityEngine;

public class PlayerMove : MonoBehaviour
{
    [Header("Movement")]
    public float MoveSpeed;

    public Transform Orientation;

    float HorizontalInput;
    float VerticalInput;

    // KeyCode 
    public KeyCode jumpKey = KeyCode.Space;

    bool Grounded;

    public float JumpForce;
    public float DownForce;

    Vector3 MoveDirection;

    Rigidbody RB;

    private void Start()
    {
        RB = GetComponent<Rigidbody>();
        RB.freezeRotation = true;
        Grounded = true;
    }

    private void Update()
    {
        MyInput();
        MovePlayer();

        if (Grounded != true)
        {
            Invoke("ReverseJump", 1.0f);
        }


    }

    
    // Gets Inputs
    private void MyInput()
    {
        HorizontalInput = Input.GetAxisRaw("Horizontal");
        VerticalInput = Input.GetAxisRaw("Vertical");

        if (Input.GetKey(jumpKey) && Grounded == true)
        {
            
            Jump();
            Grounded = false;

        }

    }

    private void Jump()
    {
        RB.AddForce(0, JumpForce, 0, ForceMode.Impulse);
    }
    private void ReverseJump()
    {
        RB.AddForce(0, DownForce, 0, ForceMode.Force);
    }

    private void OnCollisionEnter(Collision collision)
    {
        if (collision.gameObject.tag == "Ground")
        {
            Grounded = true;
        }
    }

}``` (Had to remove some stuff cuz discord)

It works well if I stand still while jumping, just not while moving

naive pawn

It is set to -5

naive pawn
#

that's very low gravity

#

use a paste site and show the full code

vast matrix
#

How do I send the code from the paste site?

thorn abyss
# rich adder show the thing you expect

Player hits x, then it should trigger the conversation (in dialogue manager, talking()) then in the talking function it should set talk to true therefore triggering the code in the update function of DialogueManager if (player.talk) {dialogueBG.style = DisplayStyle.flex} , showing the ui, and set talk to false in the notTalking function(in player controller), after the dialogue is finished.

naive pawn
#

if you have an RB, just don't touch transform

vast matrix
rich adder
thorn abyss
#

Nope

#

It shows not displaying

rich adder
#

so player.talk is false

thorn abyss
#

So i think talk is set to false somewhere

#

Ye

#

But i have no idea where and why

rich adder
#

this is another reason not all variables need to be public

thorn abyss
#

Oh

rich adder
#

go to the player class it usually tells you in IDE where that var is referenced

It just highlights them and its not really clear plus it doesnt show in another script

# vast matrix oh ok

Every jump is now a different height. And if I move while jumping the jump is twice as tall than if I stand still

or right you can right click it and do Find All References

you probably want to use linearVelocity or AddForce instead

that way you get proper interpolation and collision detection
