#

Im unsure of what the best practice would be then, but I imagine it would be easiest to still calculate it based on gravity being "down" and rotating every other vector for the purpose of the calculation

west obsidian
#

the rotating part is what Ive been trying to get this server to help me with this past afternoon

#

basically, I need to rotate the points so that the gravity vector, is equal to vector3.down

#

which is what I tried describing to you earlier

eternal needle
#

I think you can still just use Quaternion.LookRotation for that, then apply the inverse of that rotation to your other vectors. You dont actually need to rotate the gravity, just treat it as a float for the calculation.

west obsidian
#

yea, thats what I end up doing, what are the params for look rotation?

eternal needle
#

Oh wait maybe its not look rotation for this case

timber tide
#

look would give you give you a forward

eternal needle
#

If I was on my pc I could test, I'm thinking FromToRotation and then Inverse should be fine to shift the vectors to work in this calculation.
You could also do the change of basis formula but that might be harder to implement for you

I figured it out using the docs, I didnt end upt using the fromto thing but thats alright, thank you for your help

frigid sequoia
#

Ok so maybe I am crazy, I was talking about this before, but why do my proyectiles only detect collision with colliders nested under the Player EmptyObject? Like collision between all layers are enabled

rich adder
#

not enough info given here

buoyant knot
#

can you not serialize an array of tuples of ints?

rich adder
#

don't think tuples are supported

#

gotta use some type of wrapper prob

#

u not want to use struct?

buoyant knot
#

I'm just irrirtated, because I think the solution is to define a silly little struct

rich adder
#

if you got a struct why use tuple at all

buoyant knot
#

I can just do that right? [Serializable] public struct

polar acorn
buoyant knot
#

no, now I need to MAKE a struct

polar acorn
#

but a struct is easier

buoyant knot
#

for a value tuple

rich adder
frigid sequoia
#

Player is the general Empty that has all the player components; PlayerManual Transform is another empty that is just used to do simple transform stuff with ease; Test 1 and Test 2 are 2 colliders that I am using to test what the heck is failing; LookDirection is a like a ring around the player with an arrow that points and shoots towards the look direction (this is where the proyectiles are been instanciated); PlayerBody os the player character, this is the only component that has a tag other than default, it is tagged as "Player", PointLight is just a visual indicator for abilities he can use and the gather collider is a collider barely bigger than the usual one just to gather pickups

buoyant knot
#

I'm just going to define a struct, and take a shit in the unity feedback bin

frigid sequoia
#

When I shoot I get always a collision with the GatherCollider, which is fine, I sometimes get it with the playeBody if I am moving towards the proyectile direction, which is also fine; and I can get it to collide with Test2 BUT with anything else; Test 1 can never be collided with even though it is exactly the same as test 2

buoyant knot
#

This should work, right?

[SerializeField, HideInInspector] protected AnswerKeyResult[] answerKey;
[Serializable] public struct AnswerKeyResult { int rule; int matrix; }```
frigid sequoia
buoyant knot
#

does player have a rigidbody

#

collision messages primarily come from rigidbodies

frigid sequoia
buoyant knot
#

so I expect Test1 and Test2 to not see each other

rich adder
buoyant knot
rich adder
#

this one i mean int rule; int matrix;

buoyant knot
#

It might also be the ruletile custom editor

#

right, should be public

#

ya

frigid sequoia

timber tide
#

I actually prefer structs over tuples anyway especially if they're going to reassign them since they are immutable

buoyant knot
#

does it satisfy these?

frigid sequoia
#

No it doesn't but it is detecting stuff that also doesn't

#

WHY?! XD

timber tide
#

are you using trigger methods

stuck palm
#

how can i make this work if it is parented to something? it wont work if its parented to the player, for example

image.png
frigid sequoia
#

Walls and floor are normal colliders, playeBody is a normal collider AND a RigidBody, everything else is a trigger collider

timber tide
#

If you're using OnTriggerEnter and similar Trigger methods you need at least 1 thing with rigidbody and 1 thing with IsTrigger on the collider

frigid sequoia
timber tide
#

Ah, could be more related to childing rigibodies. I've not really created anything that required that yet though

#

try breaking it up and checking it all without childing

frigid sequoia
#

I literally just nested all walls under a empty with a kinematic RB and it works perfectly -.-

#

So stupid

#

Thx though

Is there a way to get all XY coordinates of a plane? For example, I am trying to make a game where balls will spawn randomly around the arena, so I want to try to get the range of those random numbers based on how big the plane I'm using for the floor is

How do I reference a Scene Gameobject in an asset

#

or wait

polar acorn
supple citrus
#

im gonna explain the situation and hopefully theres an easy way that i just am not doing

#

i have a planet asset, by default there are no planets in the scene. When a planet is clicked on i want the UI to change so i have need to reference the UI document. But since the Planet isnt in the scene yet, its just an asset

Hi Unity server. I'm nowhere near "alienated" with coding, however, I'm totally unexperienced to the object oriented paradigm. I write a lot of C and (sometimes) C++ code (C style) because I'm interested in embedding - i have a whole custom OS project and custom data structure applications, but I'm totally lost in the C# paradigm. (I know JS exists, but let's be frank, JavaScript is a tool from the depths of hell). I wanted to branch out to actual useful applications instead of reinventing the wheel, however, any introduction seems to feel.. not right to me. I don't need to learn again how variables are boxes or what an int or a boolean data type is, i just think I digest a lot of boilerplate. Is there any resource that intends to develop this coding style for a more technical viewer?

north kiln
small dagger
#

thanks

timber tide
#

oh yeah navmesh idea pretty good

small dagger
#

actually I had another idea that might work, basically I would create a separate object floating above my object, then cycle through random points, for each random point I would shoot a raycast downwards, and if it hit the desired mesh, it would trigger a spawn

#

but maybe that was what you meant with expensive manual mesh evaluation

#

idk why ruletile editor doesn't let you modify private serialized fields

polar acorn
#

From a code perspective, not really. You'll learn what a GameObject and MonoBehaviour are when you start to learn the engine

#

That's the most Object-Oriented stuff you'll need to know

#

and the rest is easily picked up on the way

fickle swallow
#

I'm assuming that every script in game gets linked directly into one file right?

polar acorn
#

One file to one class, and the names need to match

fickle swallow
#

I'm glad.

#

Question, since I saw structs existed

#

Are classes essentially, for a gross estimation, the equivalent of a reference to a struct?

polar acorn
#

Classes are objects passed by reference. Structs are objects passed by value

fickle swallow
#

I see, so It'd be like having a "struct pointer" where you can dereference and change inside different functions, for a C programmer like myself

#

Okay i think that's all i need to know

it does what you want it to do

#

So if i want prefab to have reference to object2:
object1 spawns prefab and object1 has reference to object2.
object1 calls a function defined in prefab, with the object2 as its parameter?

timber tide
supple citrus
#

because I cant tell whats going on in this example

polar acorn
supple citrus
#

Man

#

My brain

#

I have an object called GameManager that has a script that spawns the planet prefab. The planet prefab has its own script that will change the UI on OnMouseDown(). I wanna reference the UI Doc in the planet script

#

So when I spawn the planet with the GameManager script

#

I dont understand what object3 is

polar acorn
polar acorn
#

in this case, your UI Doc

supple citrus
#

So instead of doing this

#

I should set the instance to a variable

polar acorn
#

Yes, store it in a variable

supple citrus
#

Is that bad if i have alot of these planets

polar acorn
#

then set the reference you want on the new instance

quaint terrace
#

I dont know what I am doing wrong. I want TargetExp to be a reference of the corresponding Variable but it is just making a new variable and updating that:

{
    switch (monster.Task)
    {
        case "Searching":
        TargetExp = monster.SearchingExp;
            TargetLevel = monster.SearchingLevel;
            break;
        case "Mining":
            TargetExp = monster.MiningExp;
            TargetLevel = monster.MiningLevel;
            break;
        default:
            break;
    }
    TargetExp += 1;
    float tempReq = 100 * (float)Math.Pow(1.1, TargetLevel);

    if (TargetExp >= tempReq)
    {
       TargetExp -= (int)tempReq;
       TargetLevel += 1;
    }
}```

Because ill have 2 different targets

polar acorn
#

or just set the variables directly

polar acorn
quaint terrace
# teal viper Sounds like expected behavior 😅

yes the TargetExp = monster.SearchingLevel; doesnt seem right. i guess i could just change the argument from Monster monster to the direct reference itself and do public void EarnExp(int TargetLevel, float TargetExp) and just send the monster data that i want instead of trying to figure it out in the function.

Just add a offset

firstObjectPos + offset

#

offset as a vector 3

#

And this is your 2nd object spawn position

celest mortar
#

yeah

#

but then if the object is at a different rotation it would match

#

since it would only work at a specific axis

#

should i multiply the offset with the obj rotation?

Hey guys, do you know that effect in which if you collide constantly with an object it starts twitching(going back and forward fast) ? How can I evade that?

        // Calculate smooth camera shake
        float time = Time.time * shakeSpeed;

        smoothShakeZ *= shakeIntensity;

        // Update currentRotationZ before setting local rotation
        currentRotationZ = Mathf.Lerp(currentRotationZ, moveDirectionX * 1, Time.deltaTime * 2);

        // Set the local rotation with added camera shake
        transform.localRotation = Quaternion.Euler(rotationX + smoothShakeX, 0f + smoothShakeY, currentRotationZ + mouseXSmooth + smoothShakeZ);```

Move position is meant for kinematic rb

ionic zephyr

but kinematic doesnt detect collisions right?

eternal needle
#

Yea kinematic means it's basically excluded from the physics system

timber tide
radiant sail
# teal viper The issue is that you're not using lerp correctly.

thats not where my issue occurs tho, its because the smoothness value is whats only working at high fps, i want to make it stay the same smoothness no matter what fps im at but its not because the smoothness value dosent use time.deltatime and i dont know where to put it

are you talking about this line?
currentRotationZ = Mathf.Lerp(currentRotationZ, moveDirectionX * 1, Time.deltaTime * 2);

it's a rule tile

every single rule tile has to check its neighbors, and there's a lot of tiles

Well, you're back to where you started and the issue is still the same: you're not multiplying the delta value by delta time, so it behaves differently on different frame rate

whats the delta value

teal viper

Delta means change over time or between frames.

i know that but the whole reason im in here is cuz i dont know where to put the Time.deltaTime into the code to make it work how i wanted

"mouseXSmooth = Mathf.Lerp(mouseXSmooth, mouseX, -Time.deltaTime / smoothness);"
"mouseXSmooth = Mathf.Lerp(mouseXSmooth, mouseX, 1.0f / smoothness - Time.deltaTime);"
"rotationX -= mouseYSmooth * Time.deltaTime;"
"rotationX -= mouseYSmooth * -Time.deltaTime;"

Your lerping is still wrong. And the math you're doing is so convoluted it's hard to say what it results in. Try simplifying it down. Start from simple frame independent rotation and add smoother when it works.

radiant sail
#

im confused now? the rotation of the camera is working completely fine, if i wait long enough at low fps then my camera ends up in the right position but thats the issue. the part that interpolates the cameras smooth movement from point A to B isnt changing depending on the time.deltatime so if my fps is low then it thinks that im just in slow motion and interpolates it slowly but if my fps is fine then it interpolates how i want, basically i want the smoothness value to go down when time.deltatime is a higher value and make the smoothness go up when time.deltatime is a lower value.

like ive said im new to c# and most of the stuff you are saying is alien language to me.

teal viper
radiant sail
#

ive been told it means making something go from 1 point to a second point over a set time

teal viper
#

Okay. And where in your code exactly does that happen? Can you point to the line of code?

summer stump
radiant sail
#

Lerp(mouseXSmooth, mouseX, 1.0f / smoothness);

Lerp(origin, destination, elapsedTime / duration);

teal viper
radiant sail
#

the mouseX is the base movement for my camera, without the smoothing
the mouseXSmooth is the current position of the camera
the smoothness value is set to 50
and for the elapsed time part is just what i was told to put there

#

but fps wasnt put into consideration when it was made

#

i wanted to make my game play at 24 fps to mimic camera framerate but then found out my issue where its slower at low fps

teal viper
#

So, according to the first line, what happens every frame?

radiant sail
#

float mouseX = Input.GetAxis("Mouse X") * sensitivity;

teal viper
#

..?

#

What does the first line return. Can you make quick calculation in your head? Let's say mouseXSmooth is 0 and mouseX is 10. What would be the results over let's say 3 frames?

summer stump
#

Lerp(mouseXSmooth, mouseX, 1.0f / smoothness);

This will return a value 2% of the way between mouseXSmooth and mouseX... every time it is called.
So, basically no different from just using mouseXSmooth directly

Edit: oh, sorry dlich. Kinda ruined your thing lol

radiant sail
#

well idk. its just code that someone else helped me with i barely even know how most of it works

#

all i knew was that the code worked fine when i looked at it but when i added a slider for fps i found out that it only works when the fps is high

teal viper
#

Ok, so that's the greatest problem.

#

Here's one pro tip: don't use code that you don't understand.

#

Especially from random people online.

#

Because we don't understand it either, and there's a high chance the one who wrote it doesn't understand it as well.

radiant sail
#

oh.. i thought you already knew how to solve it and you were just quizzing me or smth

teal viper
#

Well,it was both. The thing is, we don't understand what the intention is behind your code logic and why it was written like that. It looks clearly wrong to me in it's entirety.

#

That's why the best I can recommend is to start over simpler and write code that does make sense.

radiant sail
#

this is what the camera does

Currently I have an OnTriggerEnter method within the teleporter and it checks the tag of the collider then I have the line
other.transform.position = Destination.transform.position
with other being the player that's collided and Destination being a reference to a Transform

it has like a flashlight that moves normal based on the mouse movement but the camera is smooth so it makes the flashlight move before the camera

#

i wanted it to move exactly the same no matter what fps im at
like so that the smoothness goes down when the fps is lower

#

thats where the idea of trying this line came but it didnt work
mouseXSmooth = Mathf.Lerp(mouseXSmooth, mouseX, 1.0f / smoothness - Time.deltaTime);

last pagoda
# north kiln are you using a CharacterController?

yeah. ahh I think I may see my problem I think the character controller might be overwriting the transform for some reason after it's changed depending on how I programmed it. I'll come back if I don't find anything

But what on earth is "this" of a vector3

polar acorn
#

Yes that is what has magnitude

north kiln
#

what does that mean

#

did you read the documentation?

polar acorn
#

what

#

Do you know what a Vector is

#

Okay so, what does a cube have to do with that

north kiln
#

okay, and did you read the documentation for magnitude

polar acorn
#

It's the magnitude of the vector

teal viper
#

Depends

north kiln
#

that is the distance between two points

#

there is no magnitude of two points

#

have you tried googling "vector magnitude"

#

and clicking on images

teal viper
#

That would depend on the use case. Outside of context it's just a number.

polar acorn
#

It's the length of the vector

#

a vector is a direction and a magnitude

Im trying to randomly generate a maze using a 3darray by assigning every cell within the array a value of 0-6 with 0 being empty and 1-6 being one of 6 different rooms to spawn in. ignoring the fact that the rooms will have to be rotated in specific ways and that they will have to click in certain ways, how would I go about just assigning every cell within the array a value of 0-6

#

Im assuming im going to use a for loop I just cant seem to visualize how in my head

but you would have 3 nested for loops to loop over the entire array

cosmic dagger
# lavish gate Mm I see, doesn’t that cause dependency problems thogh

Not really. There is always some type of dependency. The script instantiating the object can have a reference to the game manager and pass it to the object by calling a method from it

Most likely, the game manager is a singleton, which you can access from anywhere. Access the instance to subscribe to the object's event when instantiated

When the object is instantiated, call an event. Have the game manager subscribe to that event (wherever it's located). Then, it can execute its method when that event is invoked . . .

There are many ways to skin a cat . . .

I still needs to reference something in the scene though

I'm procedurally generating a mesh, and it's quite large
However, I noticed that even though there are about 100k vertices in the mesh, there's over a million indices

adding up the number of triangles doesn't even come close to that number—

could anyone explain why this could be the case? I'm not getting any errors, and the mesh looks fine, but I'm still concerned

that's true I suppose

teal viper
#

Maybe not infinite in the real sense. Unless there are duplicates. But that could be part of it.

north kiln
#

difficult to say anything not knowing what the geometry is meant to be

#

if it was a plane with shared vertices you would expect roughly 6x the amount of indices than vertices

#

if that's two-sided (sharing the same vertices again), double it

potent nymph
#

most of it are strips of polygons, like this

image.png
north kiln
#

is it single-sided?

potent nymph
#

yeah

north kiln
#

if they're just strips you would expect fewer indices than that; but I might be missing something

changing from UInt32 to 16 halved the size, but the indices are still over a million

warm depot
#

is there ever a reason to not use public variables?

eternal needle
# warm depot is there ever a reason to not use public variables?

yes, the reason is about code cleanliness and just overall code structure. It has 0 affect gameplay wise (what the user sees) but has massive changes in how you code and what other scripts do to your code. You arent supposed to use public often really at all. A public variable is basically like having a value that anyone anywhere can change, without telling you, and to something that makes no sense. You have no way of enforcing anything done to the public value, (unless we are talking about properties).
Small example: imagine you're writing a health script, it works perfectly. One day your friend works on the game, wants to test something without dying. From another script they modify the health to be infinite. You now open your project and have to solve why your health script isnt working

I'm having trouble understanding transform.eulerAngles

I'm trying to change the z euler angle of an object using a variable called FinalRotation, but I don't really get where I'm supposed to plug everything in. This is my current code:

Vector3 Rotation;
transform.eulerAngles.z = FinalRotation;
EndRoomInstantiated.eulerAngles.z = transform.eulerAngles.z;

Is this right?

teal viper
#

No. You need to assign the vector to a temporary variable, modify it and assign it back as a whole.

warm depot
#

that is so confusing

#

ok what if Rotation was a new vector

teal viper
#

Is it not?

warm depot
#

it is new

#

im a little confused on what you mean by assigning it to a temp var

teal viper
#

But in the code you shared you never use it, so I don't see how it's relevant.

slender nymph
warm depot
#

so should I do Vector3 Rotation = RotationVector;

teal viper
teal viper
warm depot
#

oh ok let me get back with new ver

#

is it like this?

Vector3 Rotation = RV;
RV = new Vector3(0, 0, FinalRotation);

teal viper
#

No... Unless RV is an abbreviation for something else..?

warm depot
#

its not

#

err

teal viper
#

Where did the transform go?

warm depot
#

I was going off of this

5867d82f8245805c2d5766dd4ce9cd2d.png
teal viper
#

It was a key concept in the issue.

teal viper
warm depot
#

Vector3 Rotation;
Rotation = new Vector3(0, 0, FinalRotation);
transform.eulerAngles = Rotation;

teal viper
#

That would work, but making the Rotation variable is unnecessary.

#

Just assign the new Vector directly

warm depot
#

ok let me try

#

EndRoomInstantiated = new Vector3(0, 0, FinalRotation);
transform.eulerAngles = EndRoomInstantiated;

#

like so?

teal viper
#

You don't need the EndRoomInstantiated. Unless you used for something else afterwards.

warm depot
#

well EndRoomInstantiated is what I'm trying to rotate with FinalRotation

#

am I going about this wrong

teal viper
#

No. It's a vector.

#

What you want to rotate is probably the object this script is on.

warm depot
#

this is what I have directly before

GameObject EndRoomInstantiated = Instantiate(EndRoom, new Vector3(X, Y, 0), new Quaternion(0, 0, 0, 0));
Debug.Log("FINAL ROTATION: " + FinalRotation);

#

I'm looking to rotate the instantiated object

teal viper
#

But you're rotating the object that the current script is on. Not the instantiated object.

warm depot
#

the script is on an empty object so that is not intended

#

how would I go about rotating the instantiated object in that case?

teal viper
#

Access it's transform and set the rotation of that transform.

slender nymph
#

btw creating a quaternion using new Quaternion(0,0,0,0) is not a valid quaternion. you should consider using Quaternion.Euler(0,0,FinalRotation) instead since you want to set that object's rotation using that value anyway

warm depot
#

oh ok

#

ill try that

slender nymph
#

and for future reference, you would use Quaternion.identity if you want to pass a quaternion that represents no rotation

warm depot
#

gotcha

#

so my new line is

Instantiate(EndRoom, new Vector3(X, Y, 0), new Quaternion.Euler(0, 0, FinalRotation));

is it valid to handle randomly generating a dungeon by creating a 2d array, defining the value of a cell in the middle of the array that will be used to indicate thats where a room should be spawned, then create two "exits" randomly along the border of the array, and a few more cells in between the exits and the middle room, then "pathfinding" somehow in between all the rooms and exits and generating rooms along the path?

with each number representing a room, 2 and 3 are entrances to the level, and 1 is the goal as this is a multiplayer game.

then I will pathfind through the generated rooms and generate the hallways

In reality what you do for this grid wont really matter, however you want to store or generate it is fine. Even in your current way, itd be a decent amount of numbers to sync but it's just something youd sync once anyways. For your question, a lot of this depends on what your gameplay should look like. Like sure you can get this working, map the ints to some room. But theres a whole leap from "I have an int" to "I'll generate rooms, pathfind, add hallways"

cursive viper
#

no more like the other one

royal garden
#

okay

#

I guess it would be pretty easy then, each index in the array would be mapped to a certain space, and you can just loop through the array and place stuff in the corresponding space

ivory bobcat
cursive viper
# ivory bobcat As is, there's quite some gap in between - I'm assuming 0 would be considered th...

well, yes this is a sample I used to show the concept, I can edit how many rooms generate. However the point of the game is to race against the enemy team to reach the middle "1" room and get the "flag" inside and bring it back to your team's exit. So it is beneficial for the gameplay to have lots of useless rooms to get lost in. However I want to put weapons or health items, maybe powerups in those rooms to not make it completely a waste of time visiting them

eternal needle
#

Yea definitely look at algorithms for generation before considering how you're gonna store these tbh.
And mapping an int to your room is fine, you just need to sync this once for multiplayer (assuming rooms dont change once generated) so it doesnt really matter what you do.

#

You can always profile later on if its sending too much data, then try to compress. Realistically you could compress a lot of the data since you probably only have a few room types

cursive viper
#

what do you mean store these?

eternal needle
#

Your current method of storing is in the 2d array

#

A way of holding the data

cursive viper
#

oh right right

ivory bobcat
#

After you've designed or acquire the algorithm to generate the wanted pattern, should you then want to consider the data type to hold the information.

Oh, oh. That's not how I explained my problem. I want to create this component right in the script. To change the settings of this component in the Inspector immediately. Screenshot of the example:

To have this component right in the script

languid spire
#

if you mean to embed another component within your Monobehaviour, that cannot be done

split dragon
teal viper
#

It could be done with a custom editor😬

languid spire
#

you would still need to have the TMP_Text as a separate component though which would be very confusing

Yeah

how do i activate it when i use the vr controller trigger

#

using the openxr toolkit

#

idk why it's not working, and yes. i did check out the documentiation but i don't get it

languid spire
# split dragon Sadly. Thanks

Actually there is one thing you could try. Instead of your class inheriting from MonoBehaviour inherit from TextMeshProUGUI

#

you would still need a custom inspector though

do you have an input axis set up called Veritcal? also !code 👇

this is the error

}
#

why does it not rotate the player

slender nymph
#

probably because it doesn't find it

#

check your console for errors

nocturne phoenix
#

there are no errors

#

like if i walk forward while looking sideways

#

it doesnt go sideways

slender nymph
nocturne phoenix
#

wait

#

is this error related to this script?

#

UnityException: Find is not allowed to be called from a MonoBehaviour constructor (or instance field initializer), call it in Awake or Start instead. Called from MonoBehaviour 'Aim'.

#

its this script

#

fuc

slender nymph
#

yes. and so are the NullReferenceExceptions you got as a result of that first one

nocturne phoenix
#

why does the other stuff work tho?

#

like i can still look around

slender nymph
#

because the null reference exception happens on the last line of your Update method

nocturne phoenix
#

ah

#

can i put the variable in update method

#

OH GOD

#

yeah

#

i shouldnt have done that

#

it fucked up bad

slender nymph
#

that's not a result of you getting the player object inside of Update. that's because your code is scuffed

nocturne phoenix
#

whats the problem in my code?

#

i am new so i will be thankful if you can help

slender nymph
#

player.transform.Rotate(transform.eulerAngles)
explain, using your own words, what you think this does

split dragon
nocturne phoenix
slender nymph
#

yes, that is exactly what it does. each time you call it

nocturne phoenix
#

oh

#

what shall i do instead then

#

i need the player to rotate so the movement happens in the direction i am looking

slender nymph
#

i'd recommend watching a tutorials for this. there are literally hundreds that will cover what you are trying to do

nocturne phoenix
#

i have a question tho

#

what is the transform.eularAngles changing rotation of

#

because if not the player (which the script is attached to)

#

how is the camera moving

slender nymph
#

is the camera a child of the player

nocturne phoenix
#

yes

slender nymph
#

so if this component is attached to the player, it rotates the player which means the camera's rotation will change along with it because it is a child of the player. also if this is attached to the player, then why are you trying to find the player with GameObject.Find? transform refers to the player's transform

nocturne phoenix
#

so why does it like

#

not change player's move direction

#

if the player is being rotated anyways

slender nymph
#

probably because this code has nothing to do with moving the player

nocturne phoenix
#

thats another script

# 
using System;
using System.Collections;
using System.Collections.Generic;
using Unity.VisualScripting;
using UnityEngine;

public class PlayerMovement : MonoBehaviour
{
    [SerializeField] int speed;
    Rigidbody rb;
    // Start is called before the first frame update
    void Start()
    {
 
        rb = GetComponent<Rigidbody>();

        speed = 5;

    }

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

    {

        float verticalInput = Input.GetAxis("Vertical");
        float horizontalInput = Input.GetAxis("Horizontal");


        if (Input.GetButtonDown("Jump"))
        {
           rb.velocity = new Vector3(rb.velocity.x, speed, rb.velocity.z);
            Debug.Log("Jumped!");
        }

        rb.velocity = new Vector3(horizontalInput * speed, rb.velocity.y, verticalInput * speed);
   
    }
}
slender nymph
#

there you go, the rotation of the object is not going to affect how it moves based on this code. you need to create a Vector3 from your input and use transform.TransformDirection to turn that input from local space to world space since Rigidbody.velocity is in world space

nocturne phoenix
#

lemme go just read on docs what transform.TransformDirection is

#

😅

nocturne phoenix
#

that was written in docs too

They can both yield the same values if there's no parent

nocturne phoenix
ivory bobcat
#

But normally what you'd see in the inspector would be the local values. If you equate all of the offsets done by parents and whatnot, the resulting value would then be the world space.

nocturne phoenix
#

ah

nocturne phoenix
#

does vector 3 use world space

#

or transform?

ivory bobcat
nocturne phoenix
#

i read the wiki a little and all i figured was it transforms from local space to world space

ivory bobcat
#

For instance, if there was an object (A) at (10, 0, 0) and it had a child (B) at (12, 0, 0):

  • A would have a world position of (10, 0, 0) and a local position of (10, 0, 0).
  • B would have a world position of (12, 0, 0) and a local position of (2, 0, 0).
    The local position would be what you'd see in the inspector though.
#

In your case, you'd be working with directions instead and transforming the values from local to world.
The inverse function would do the opposite if you're wanting to convert something from world to local.

#

All of this information is of no use if you don't know why you're needing to do what you're doing though UnityChanFinished

Hi first time back to Unity in years so I’m super rusty. I’ve been following one of the millions of Minecraft clone terrain generator tutorials and in this particular tutorial they use a ScriptableObject which holds a heap of data in an array of texture locations to a tilemap. It works fine but it really doesnt seem scalable at all.
I have two questions regarding this-

  1. This system generates a mesh using two materials. Water and the default. Is it a bad idea to have a separate material for every single block type? I understand calculating uvs and loading shaders is costly and stacks up with multiple unique materials. But it really seems way more scalable long term.
  2. Is generating Materials programmatically costly? I want to make this easy as possible. My vision is to just have a folder full of images and some sort of data object to keep track of block types and texture mappings. Making an individual material for each item seems useless when the only thing changing is the texture. Is it a bad idea to generate it programmatically?
    My main concern is having one gigantic tilemap for when I have 40+ blocks and want to avoid that

Apologies for the long question

You still need to configure the IDE like you were already told

ivory bobcat

And Unity doesn't use python (relative to your comment about making a script in python)

but I'm not doing it, it's my first time I copied it from a tutorial

Is there any difference between Physics.Raycast y Physics2D.Raycast applied to a 2D space?

charred spoke
#

As far as I know one will work against regular colliders and the 2d version will work against the 2d version

#

Ie you cant hit a 2d collider with a Physics.Raycast and vice versa

#

the 2D physics system contains all Collider2D. The 3D physics system contains all Colliders. Physics2D.Raycast only queries 2D colliders. Physics.Raycast only queries 3D colliders. The two are totally separate.

nono, i want the player to collide with the ball only. Ball has to collide both with walls and players

Now it should be clearer

make the wall colliders triggers and handle the collision with the ball yourself

I think there are physics settings that configure which layers collide

Hey, guys! I have a problem that I can't solve already 2-3 days. I have made a GameOver screen and I want to enable pause menu screen whenever the game is not over with an escape button but when it is over to not interact with that button and not set the pause menu screen to active. I think I have everything fine in code, but I just don't know what is happening maybe I set a bool to a value that is not appropriate?

#

Here I give the input for my pause menu screen, I have tried to put debug messages to break the problem to subproblem:

{
    Debug.Log("Game is over: " + gameIsOver);

    if (!gameIsOver)
    {
        if (Input.GetKeyDown(KeyCode.Escape))
        {
            if (pauseIsActive)
            {
                pauseIsActive = false;
                pauseMenuScreen.SetActive(false);
                audioManager.mainGameMusicAudioSource.UnPause();
                audioManager.PressButtonSound();
                Time.timeScale = 1f;
                Debug.Log("Pause menu screen is disabled after delay!");
            }

            else
            {
                pauseIsActive = true;
                pauseMenuScreen.SetActive(true);
                audioManager.mainGameMusicAudioSource.Pause();
                audioManager.PressButtonSound();
                Time.timeScale = 0f;
                Debug.Log("Pause menu screen is enabled after delay!");
            }
        }
    }
}```

it is for me

I want to interact with the escape button whenever the game is not over and not interact with that button to open the pause menu screen when the game is over. Is that better?

#

@polar acorn

rich adder
#

still think my suggestion would help ya

trail fox
#

agreed

sage mirage
#

So, I have to make enum and add there the game states?

rich adder
#

if you press escape in the Game state then you cannot possibly trigger the one in GameOver state

#

etc

polar acorn
sage mirage
cosmic quail
#

or just if player == dead then dont open the menu, thats also possible

#

but having game states looks better

sage mirage
rich adder
#

so many bools can be solved with enum 🤷‍♂️

rich adder
#

in gamemode it pauses, in gameover does whatever, and so forth

#

i can give you a quick example for code ill hop on my pc rq

cosmic quail
#

and the gamestate is preferably inside a singleton right?

rich adder
#

in the beginning esp sure thats a good place

#

generally only my gamestate manager can change itself

#

it listens to particular events but that gets complex quick

#

so a switch statement would do here in a singleton

cosmic quail
rich adder
#

and the states grow within the game for example

polar acorn
# sage mirage Yeah!

Okay, yeah, sorry. I'm incredibly undercaffeinated right now but it looks like Nav has you covered on a solution

If you divide an integer by an integer, the result is also cast as an integer, meaning the decimals get rounded. Your fraction was never high enough to reach the next whole number, so it just kept generating the same result

you're accessing transform without checking if ray hit
