#

so what's the result of Vector3.Project(Vector3.one, Vector3.zero)

#

for example?

swift crag
#

That's not a meaningful operation

#

Vector3.zero doesn't point anywhere

rare basin
#

yes sorry, Vector3.right*

#

for the 2nd one

swift crag
#

The diagonal arrow is the original vector. The vertical arrow is the result of using Project with Vector3.up

image.png
#

And the horizontal arrow is the result of using ProjectOnPlane with Vector3.up

swift crag
rare basin
#

okay i get it now

#

i somewhat always thought it is similiar to Cross product

swift crag
#

I added a plane to this imagine because its normal vector is Vector3.up

#

ProjectOnPlane flattens your vector onto a plane with the given normal vector

#

So if you add the results of Project and ProjectOnPlane up, you get the original vector back!

#

@sonic dome so, if you use those methods to split your velocity into two pieces, you can modify just the horizontal velocity, then put them back together

rare basin
swift crag
# 
Vector3 vertical = Vector3.Project(rb.velocity, Vector3.up);
Vector3 horizontal = Vector3.ProjectOnPlane(rb.velocity, Vector3.up);

horizontal = // do something to it here

rb.velocity = vertical + horizontal;
sonic dome
swift crag
#

If gravity goes straight down, you could also just do this

# 
float yVelocity = rb.velocity.y;
Vector3 velocity = rb.velocity;
velocity = // do something
velocity.y = yVelocity;
rb.velocity = velocity;
#

Project and ProjectOnPlane work correctly for any direction

#

I think it's also a little more clear what you're actually doing

swift crag
# 
Vector3.ProjectOnPlane(foo, bar) == foo - Vector3.Project(foo, bar)
#

Project, Angle, and Dot are really useful.

an animation event is called only once for every time it plays in an animation right? also, if i want to reference an animation event in another script, how do i do that? like

once animation event in script 1 is called, something should happen in script 2

Or fire an event in script 1 and listen in script 2

shell sorrel

the animation event will only call on a script on the same object as the animation

how would a fired animation event look then, would it be AnimationEvent(1)? or would something else be in the parentheses

you dont call animation events via code

but in the animation timeline

shell herald

yes, but like, i want to know when it is called. im a coding noob. i basically want a bool to only be true the frame the animation event is called and then be false again

make 2 animation events

one setting this bool to true

second estting this bool to false

You need to set the position itself, you cannot update just a single axes.

#

So give your gameObject.transform.position = a new Vector3 that includes the new x position you want.

or save position to a temp var modify x then assign it back

#

a loop is a block of code that repeats as long as a condition is met.

#

OnCollisionEnter is invoked every time you collide with another non-trigger collider.

#

Why do you think the score is only going up once? Are you looking at the inspector for this component while the game is running?

swift crag
#

It's used to indicate that a function returns nothing.

#

private is an access modifier. It's used to control who is allowed to see a function, field, etc.

late bobcat
#

exactly as fen said, when you say "void" "int" etc before a function name you're just indicating the type of value the function should return

swift crag
#

It also happens to be the default access modifier for methods, so both Start and OnCollisionEnter2D are private.

#

Both methods return void, so neither of them returns a value

An infinite loop will freeze the editor, since the code never finshes running.

You can declare several methods in a class, of course. You just have to declare them one at a time.

buoyant knot
# frigid sequoia Guys, this is more like a technicism, but how do I check for OnCollisionEnter() ...

  1. OnCollisionEnter has an argument of type Collision, which contains a reference to the thing you hit. You can check the layer there.

  2. The object has a layer, and the physics system settings can be changed to automatically count 2 layers as not colliding with each other. Which makes OnCollision calls not trigger

  3. Colliders have layer override options, so you can make that specific collider not count with colliders of a specific layer.

#

If you are going to be filtering out a lot of collisions, then you want to use layer overrides or layer collision settings so these methods don’t get called in the first place

#

so you know how mario maker lets you put 100 goombas all in a little ball, touching each other? That would be 100^2/2= 5,000 collisions every frame. In this case, you would make the goombas not count collision with each other, so physics system doesn’t even call those methods 5,000 times

timber tide
# remote lynx ok ty

Ok, yeah. You need at least 1 rigidbody from either triggering object, but you can set it to Kinematic so it wouldn't be affected by physics otherwise. As for IsTrigger on the collider, only one is required and it doesn't matter who has it, but doing this also prevents OnCollision methods from triggering.

buoyant knot

# shell sorrel show a example hard to say what you are talking about

I am trying to make a scoreboard

When the collision happens, the score goes up by 1 only once and the next time it collides it doesn't work anymore,
so I tried to write;

{
 OnCollisionEnter (Collision collisionInfo)
   {
    If (collisionInfo.collider.tag == "Obstacle")
       {
          score = +1;
       }
   }
}

But it says I have to define "Oncollision Enter" When I try to make it " Void OnCollisionEnter" it gives me an error.

image.png
swift crag
#

You've just created a local function

#

OnCollisionEnter is only usable inside of Update

#

Unity has no clue this thing even exists. Don't do that.

buoyant knot
#

a local function called OnCollisionEnter 😂

shell sorrel
swift crag
shell sorrel
#

so yeah dont define a function inside a other function

swift crag
frigid sequoia
buoyant knot
#

unity only sends messages to call OnCollisionEnter on collisions if you have a function called OnCollisionEnter, that takes a Collision argument, and returns void

swift crag
#

If you're having problems with the score not increasing, then you need to figure out:

  • whether OnCollisionEnter is running at all
  • whether you're hitting something with the correct tag
frigid sequoia
#

Don't really know why

timber tide

honestly just spherecast and use a layer mask :)

Layer #5 corresponds to the integer 5.
A layer mask is a 32 bit integer, where each bit corresponds to whether or not to check interaction with that layer. So a layer mask that only touches layer 5, would be layer mask 64

and a Layer mask that includes layers 0 and 2 would be equal to 000…00101 = 5

that will combine identical log messages into one

this plugin has code to automatically generate a class called Layer, which contains public consts for specific layers and layer masks in your game

icy junco
ivory bobcat
icy junco
#

if...

ivory bobcat
#

I'm guessing the if-statement

frigid sequoia
buoyant knot
#

so if I have Layer 5 being terrain, then it will have Layer.TERRAIN, which is automatically 5. And Layer.TERRAIN_MASK, which is automatically 64

icy junco
ivory bobcat

Yeah, so playerController is null and accessing the gameObject property threw an error because playerController was null.

swift crag

then you need to go to project settings, and go define the layers that Wall can interact with

#

you will tear your hair out

#

Project Settings => Physics

#

there will be a giant matrix of checkboxes with layers

ivory bobcat
buoyant knot
#

If X and Y have a checkbox on, then they interact. Otherwise, they do not (by default) without layer overrides.

frigid sequoia
#

So just to be clear, when I am declaring variables, can I call a Layer instead of a LayerMask? Cause I don't think it lets me declare a Layer in the script, just LayerMask

swift crag
#

No, that isn't built in, unfortunately.

buoyant knot
#

no

#

Layers are ints

#

The logic for drawing a list of layers is in there, but it isn't be applied to anything

#

I believe you can make a custom property drawer for this?

#

It came up in this server recently

buoyant knot
#

a layer mask is a bitmask

#

the different 0 and 1 directly mean like 32 separate booleans in one integer

swift crag
#

Both layer IDs and layer masks are integers. That's why it's easy to mix them up.

#

C# won't stop you from doing if (thing.layer == myMask)

because they're both integers, making this a completely legal comparison

What was the actual issue?

frigid sequoia
#

Ok lets play it slow to make sure we are talking about the same. That think in the corner, that dropdown; those are layerMASKS, right?

Those are layers.

#

You are picking which layer the object is on

#

The object is on the Character layer in this screenshot.

buoyant knot
#

this way, if I want to filter for specifically layers 1, 4, 7,8,9, 23, then I can make a single layer mask that has those bits on. Then I check vs layer mask, so I don’t need to use 7 if else if else if to check if that layer is relevant

You can't be on two layers at once.

swift crag

#

he doesn’t understand the difference between layer mask and layer

swift crag

frigid sequoia
# swift crag Those are layers.

Then why the hell does it shows the Layer Dropdown when I am assigning a LayerMask variable for a script in the inspector?

swift crag
#

you're choosing which layers are included in the LayerMask.

buoyant knot
#

layer mask is 1 int that corresponds to booleans for 32 layers (some combination of those 32 layers)
a layer is just an integer for its own layer ID.

ivory bobcat

you cannot convert a layer mask to a layer, because the layer mask could correspond to 0 layers, or multiple layers.

#

I used Shapes to create a cursor in an RTS once

#

the problem I ran into was that drawing in AfterPostProcess with dynamic resolution scaling is broken, but drawing in BeforePostProcess means that the damn thing gets post-processed!

rich adder
#

is that a package?

swift crag
#

Yeah. It's a package for drawing nice lines, discs, etc.

rich adder
#

Oh nicee, i only knew about GL. Gotta look into shapes sounds fun

I have solved my problem here but I have a quesiton 🙂

The script won't accept TextMeshPro as a "text", in order to fix it I have to remove it and add a text component. But is there a way to use TextMeshPro instead of a Text component?

rich adder
#

normally you use TextMeshProUGUI or whatever

open apex
rich adder
#

but TMP_Text is shorter and the base class that will accept any TMP variance

rich adder
open apex
ivory bobcat
swift crag
#

TMP_Text is a parent type of TextMeshPro and TextMeshProUGUI.

rich adder
#

mymyb underscore too

swift crag
#

There are differences between non-UI and UI text, but they're not relevant in most cases

#

so you can just use TMP_Text to cover both

rich adder
#

so used to IDE putting it there for me when i just type TMPT

#

xD

open apex

i thought UGUI covered both?

I need to name a dictionary that maps "things that make noise" to "loudness of perceived noise"

#

struggling with a name

#

intensities sounds more like a list or something

shell sorrel
swift crag
#

perceptions is closer but it's such a general name

rocky canyon
#

AudioMagnitudes

swift crag
#

and "Perception" already has a very well defined meaning

#

The values fade to 0 and get removed from the dictionary, so maybe activeNoises or something..

polar acorn
rich adder

bigNoisesDic

rocky canyon

heyya! tbh this is my first time coding anything beyond html so you may need to explain any errors to me very simply :,)
i'm creating a dialoguemanager by following this tutorial : https://www.youtube.com/watch?v=vY0Sk93YUhA&t=840s. however i get this error:

here is the cs file:
https://pastebin.com/P2b0v5kC

also, i'm using inkly to create a dialogue branch that goes down 3 layers of options, however the dialogue stops after the first set of options are selected. if someone could point out/fix that issue that would help tremendously :)

rich adder
buoyant knot
fleet willow
rich adder
#

and you dont know anything about fixing it

buoyant knot
#

there are many ways to represent a rotation, but at the end of the day, some sort of rotation operator/matrix is needed to rotate

ivory bobcat
polar acorn
fleet willow
#

sigh

west obsidian
timber tide
#

why you need rotation

rich adder
#

the price is cheap enough to be worth it though

west obsidian
#

like if I were to have point A be (0,0,0), point B be (0,1,0) and T be (1,1,0) then it would be as simple as removing the z coord

#

but Im rusty on rotation matrices and stuff

rich adder
#

I'm tempted of making one of these Templates myself ngl xD

west obsidian
#

I assume you do something like take the cross product to find the normal of the plane, but I dont know how to find the rotation of that normal

buoyant knot
rich adder
#

FromToRotation

buoyant knot
#

Quaternion contains methods to apply rotation operators in true 3D. But might not be needed if you are actually in true 2D

west obsidian
#

not like the shadow or anything tho

#

I want to find the local coordinates on the xy plane that goes thru the 3 points

buoyant knot
#

you can also do the math by hand. Wiki has the very simple math

west obsidian
#

ya like a1 is multiplied by the cosine of the angle

#

so there is deformation

buoyant knot
#

a projection takes only the components of the vector that would be in plane

open apex
#

Hello it's me again, I have made a code where when the player gets in touch with an obstacle and it gets replaced with another destroyed version of the player. This creates the illusion of destruction, the code works but it's faulty, it only runs once. when I drop to the game it touches the ground and after it, it won't run again. How can I make it to keep on running until the even occurs?

image.png
buoyant knot
#

it does not rotate the vector

west obsidian
buoyant knot
#

the norm will almost certainly decrease

west obsidian
buoyant knot
#

then why don’t you project it, and change the magnitude

polar acorn
shell sorrel
west obsidian
buoyant knot
#

project the vector onto the plane, then change the magnitude to match the original. And you need a special case where the original vector is normal

rich adder
buoyant knot
#

which you’d need anyway

west obsidian
buoyant knot
#

that’s the easiest way to do that

west obsidian
#

are you talking about the point as the vector?

#

cuz if so its already on the plane lol

buoyant knot
#

there are no points here

#

you have a 3D vector, and want it to be rotated such that it is in a 2D plane

#

what you have asked for is projection + rescale

open apex
west obsidian
#

not completely, I want to find its orientation relative to an axis

rich adder
west obsidian
#

so I guess projection works, but there is an extra step of finding the angle between it and the axis

buoyant knot
#

that has nothing to do with a 2D plane then

open apex
west obsidian
#

well my points have to do with a 2D plane, the vector is how I align my arbitrarily rotated 2D plane with a 2D plane of normal (0,1,0)

rich adder
shell sorrel
west obsidian
#

I have a plane passing thru points A B C, I want to find the local coordinates of C

open apex
rich adder
buoyant knot
#

idk man. once you can better articulate what you need in terms of vector/matrix operations, everything will become clear

rich adder
#

since you're destroying it

buoyant knot
ivory bobcat
open apex
#

It supposed to get destroyed only when it hits an object, when the game begins it hits the ground and the script runs and then it doesn't run again. It only runs once only (it runs when it's not supposed to)

west obsidian
#

whoops, wrong message

open apex
#

I couldn't explain myself

west obsidian
#

basis vectors

buoyant knot
#

the local coordinates of anything in 3D require 3 basis vectors to express

ivory bobcat
#

Maybe consider destroying the other object colliding with this object

rich adder
open apex
#

no

west obsidian
buoyant knot
#

vectors form a basis if they are linearly independent, and fully span the space

rich adder
buoyant knot
rich adder
buoyant knot
#

if you give me an arbitrary 2D plane, and tell me to get the local coordinates of a 3D point, I will tell you that your query makes no sense

west obsidian
#

I have 3 3D points, A B C

open apex
west obsidian
#

I want to orient them so that they are all on the same 2D plane with a normal of (0,0,1)

#

how do I do that

buoyant knot
#

still impossible

#

there are an infinite number of answers that would satisfy that

west obsidian
#

how? I did this a while back when I was making a 3D renderer

buoyant knot
#

because you still haven’t defined your new coordinate system

open apex
#

something faulty with the script

#

forget about it I will just delete it

west obsidian
buoyant knot
#

if order to change from one coordinate to a different coordinate system, you need a 3x3 matrix

west obsidian
#

Im staying in euler coords the whole time

buoyant knot
#

this 3x3 matrix effectively contains information for all 3 axes for the new coordinate system

#

wtf are euler coordinates? that isn’t relevant here

meager sentinel
#

Someone knows why my VSC ide is so buggy? It worked the last week, and now it donts

buoyant knot

you are doing a simple linear transformation. but you can’t do that unless it is fully defined

buoyant knot
#

let’s say I’m standing on the plane, and forward is my X axis

#

i can turn around

#

different x axis. still satisfies your constraints

#

different coordinates

#

therefore your question is ill posed

viewspace -> clipspace -> screenspace using a projection matrix is usually how computers render 3D objects to our screens so you can research into that. As for your question, I'm still not sure what you're aiming for, as to solve that specific problem I'd just rotate until I eliminate an axis.

im not getting any errors issue is in the script

in bullet

in turret

timber tide
#

you can further debug your bullet code

#

need to figure out if it's your targeting or how you're doing the speed

polar acorn
#

Unrelated but if the literal first thing you do after instantiating a bullet is get the Bullet component from it, why not just make that prefab field of type Bullet and skip that step

scarlet hull
scarlet hull
timber tide
#

similar to how you're declaring your variables as transforms and gameobjects

#

you specifically want to work with the types, so you might as well reference them

scarlet hull
#

since i started this way im going to finish it like this but i will keep that inmidn for the next time

polar acorn
scarlet hull
#

aah

#

got it

timber tide
#

it's just ambiguous

#

benefit of having your fields as their specific types also makes binding stuff in the editor clearer

#

so you dont accidently bind the bullet field with a type of gun, because you instead wanted to declare the field as a gameobject

at least not one you can do with a 3x3 matrix

you would need a rotation operator to transform the whole plane about some defined center.

#

only then can you get the difference in position, and add the vector

one of those is a function the other is a property

they are not the same

though a property in this case would be a better choice

scenic urchin
#

I'm just a bit lost about where to use each in this kind of situation

properties are essentially functions that look like regular field access

like public Vector3 Velocity => _rig.Velocity; then on access it would just be thing.Velocity

#

does SetParent work like that?

scarlet hull
#

it worked

buoyant knot
#

also that would at best try to move the child to the root of the hierarchy

buoyant knot
shell sorrel
buoyant knot
#

that would just set the i-th child to be in the root of the hierarchy

static bay
#

ya

#

bit unintuitive but meh

terse osprey
#

yes that is what I want to do, basically just unparenting the child and setting it in root

#

but I only want it to happen to the singular child that is active at the moment

buoyant knot
#

i would debug.Log to see if that line even gets called

shell sorrel
#

could break out of the loop if you just want the first one it finds

terse osprey
#

since there is only one active at the time so all active children works fine by me

#

but it doesnt unparent any at all

buoyant knot
shell sorrel
#

also there are multiple ways to check for active

buoyant knot
#

also, if you unparent it successfully, then you will get an index our of bounds error. because you changed the list of children. So you need to break

shell sorrel
#

the one you used would return false if the object was active but its parent was not

#

how to check whenever a player is holding down a button and do smt when the button is holded

buoyant knot
#

look up tutorials for it

static bay
native flicker
#

no, no key

#

a actual button in a gui

terse osprey
#

maybe I am just trying to do this a really stupid way but basically I have an inventory and whenever I pickup a gun it is added as a child of the inventory. I want that if I try buying a 3rd gun so above my max child limit the gun currently active is replaced by the new one

shell sorrel
native flicker
#

alr thx, i alr tried some stuff but none rl worked im prob doing smt wrong

shell sorrel
#

using IPointerDownHandler and IPointerUpHandler and a Update

static bay
shell sorrel
#

set a bool true OnPointerDown, set it false in OnPointerUp then in Update do what you want to do while the bool is true

buoyant knot
#

that is a recipe for disaster

^ The hierarchy is really for managing the active state of things and organization.

timber tide
#

it can work

#

unless you have an unlimited inventory then you're asking for a scene of gameobjects

#

of guns

terse osprey
#

There are a total of 5 weapons that one can get and up to two can be in the inventory at one time

#

I dont quite understand everything you guys say but ill do some research into the things you guys recommend and get it working hopefully

Thankyouu

Hello I am currently calling an idle animation in update like this

void Update()
    {
        if(!playerUnit.IsPlayingAttack && !playerUnit.IsPlayingIdle)
        {
            StartCoroutine(playerUnit.PlayIdleAnimation());
        }
    }

Im having a problem with the fact that when I want to play the attack im basically always playing the idle so it doesnt work, if I try and WaitUntil in my attack anim the update always sets it faster

buoyant knot
# timber tide it can work

don’t enable him, mao. Using parenting to effectively manage inventory, which requires a lot of querieing, size control, sorting, etc… Doing all that in hierarchy is a really terrible idea

#

Just use a list

terse osprey
#

The issue here is that I am using assets from the unity store and those work by adding a weapon as a child to have it be part of the inventory. Maybe ill try changing up the system it self

timber tide
#

well, you'd have a manager. The only difference between storing it in data vs having it on the scene is you don't need to instantiate the data onto a gameobject everytime you want to use it

hybrid tapir
#

how do you make a value in an inspector seen but like dimmed out and uneditable? i thought private and [serializefield] might do it

polar acorn
timber tide
#

so more mem vs overhead elimination, but otherwise for small amounts not really a concern.

buoyant knot
timber tide
#

oh yeah, I wouldn't deparent and stuff, but you can just get a list of all current siblings and keep pointers to them in a list

buoyant knot
#

like, sorting the list, or filtering through, or whatever… that is going to be a massive pain

buoyant knot
#

so you need to go reading the hierarchy to know the contents of the inventory

#

you need to parent, deparent to move things into or out of inventory

#

and querying or sorting the inventory is a mess

#

all this, instead of a list

timber tide
#

yeah I wouldn't care too much about how it looks on the hierarchy, you'd just read the pointers from the manager and then child them to the inventory with an Add method

buoyant knot
#

that’s what i’m getting at

timber tide
#

again, I wouldn't do this for a large inventory of stuff, but if you wanted to show your side arm equipped to your guy and your rifle (the whole load out), you might as well just keep it all on the scene

buoyant knot
#

the hierarchy exists to maintain specific relationships between gameobjects. Not to store misc gameplay information, like what is or is not in your inventory

#

imo, my limit for doing that is an inventory size of one. Where there is supposed to be a unique object parented/child

#

and even then, both will have a monobehaviour to establish and maintain the connection

How do i fix this? it wont let me add a script into a model i imported from blender.

make a prefab from that model, then add the script in the prefab

Hello, i get the " Object reference not set to an instance of an object " error and I dont understand why, when using the following code to create floating damage text popups

polar acorn
#

There's like fifty things it could be

eternal needle
#

That's definitely a line of code

polar acorn
#

so the first step is to split that up so you can find out where the problem is

#

Well, the 0th step is getting rid of the pointless .gameObjects

untold saffron
#

i think i found that the problem is probably the GetComponent<>() part

#

but my object has a textMesh i dont understand why it returns null

eternal needle
#

70% of that line can be taken out if you directly reference the script for Instantiate

rich adder
eternal needle
#

And then you dont have to worry about keeping the same structure, where you look for a certain child

polar acorn
#

Yeah just make damageTextPrefab of type TextMeshProUGUI

#

Ah, wait, no it's in a child object

untold saffron
eternal needle
rich adder
#

using GameObject is kinda useuless

eternal needle
polar acorn
rich adder
#

make parent have script and prefab has the TMP reference of child, use a method on that script to do ChangeText

untold saffron
#

wait i dont understand

#

how should i do that?

rich adder
#

personally I would make these a Pool of DamageObjectsText

#

instantiating a bunch of new prefabs on each damage sounds expensive

untold saffron
#

oh okay thanks

rich adder
#

make the main script on it that controls the TMP_Text

#

everytime you get from Pooled objects set the text to new damage amount

how would I find the angles to rotate that vector so that it aligns with (0,-1,0)

Hey I plan on making a gameElementsManager of some sort to help make designing my game a lot easier. I want to be able to just add from my list of enemies to the scence when I right click on the heirachy window. I want to be able to just add playerElement to the list of playable characters and have it reflect on everywhere with a send of probably provided animations in it's own animation controller. I also want to implement my map generation feature. I have no idea how to start with creating it as I am used to just draging and dropping everything thing into the scence. I need help on an explanation on how to go about with starting to design it or a link to some tutorial could also help

west obsidian
eternal needle
#

Then take a minute to think about what you need. You asked for the angle, I gave you a method for the angle

west obsidian
#

I need 2 angles

#

2 rotations along the x and y axes

eternal needle
#

Ask it in terms of your game, not in terms of code. What are you actually trying to do in your game?

#

None of this "I want angle xyz euler this that", what is the gameplay mechanic

rich adder
#

there is probably a better solution to the problem

#

but we dont know the problem if you ask solution for Y when you're solving X

if I have 2 points, A and B, and an initial velocity v, and an arbitrary gravitational acceleration g, with gravitational vector G, then what is the velocity vector to send the object from a to b

not at all

gravity exists

polar acorn

That's the direction between two points

west obsidian
#

yes I am aware

in before remove an axis and rotate and be done with it all

I did the math, and figured out the equation for the trajectory in 2D

i hate reading

since a plane can go thru any 3 points, I want to rotate the plane to 2D so I can do the trajectory calculation

west obsidian

yeah, call it game manager and make it a singleton

then you can add more and more

i need like 12 more credit hours for a bachelors in math but I can't be bothered. Maybe if quaternions start kicking my butt harder I'll reconsider.

Anyways it's better to ask in a unity context because there are specific methods that exist, in a math discord they may just think you are doing all steps yourself

(oh ya, forgot to add, using unity's rotation order)

eternal needle
# west obsidian https://www.desmos.com/3d/cefa2669ea

How come you need it by individual axis? If we are talking about any vector at all then sometimes it would be the Z axis you rotate. Anyways you can get this result by doing Quaternion.LookRotation and I guess converting to the euler angles. Although theres no guarantee x and y have values while z is 0.

west obsidian
#

I dont mind, any axis works really

eternal needle
#

Working with eulers are kinda shitty in some cases

So I have this problem that's really bugging and confusing me. I made a door script where if you press F on it, it will play an animation of it closing or opening, I did this using Animator Booleans. This is used by 2 scripts, one which has the method of Opening and closing and then another Interact script which checks if I'm pressing F on something Interactable and if so, it will call the necessary function.
This is the Door Script:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class DoorOpenFront : MonoBehaviour
{
    public bool IsOpen = false;

    public AudioSource OpenSound;
    public AudioSource CloseSound;
    public Animator animator;

    // Start is called before the first frame update
    void Start()
    {
        
    }

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

    public void Open()
    {
        OpenSound.Play();
        animator.SetBool("Open", true);
    }

    public void Close()
    {
        CloseSound.Play();
        animator.SetBool("Open", false);
    }
}

Tell me if you want a look at the Interact script.

I removed about 40 eulers methods last week and replaced all with AngleAxis if that answers some questions how much trouble I've dug with eulers

rich adder
dusky bay
eternal needle
#

Oh yea AngleAxis exists too

west obsidian
# eternal needle Better to remake something now rather than continue with a suboptimal solution

considering you claim you have a math major, could you maybe see if there is a simpler approach to something after all? I have 3 points, being point A (initial pos) point B (target pos) and the gravity vector, and I want to orient all of these points in such a way that A is at the origin, and the gravity vector (normalized) is equal to Vector3.down, I just need the transformed location of point B

please ask away as I seem to be terrible at clarifying stuff

Theres also more to consider because you can launch an object at different heights and still achieve the same result. So its up to you to decide what trajectory height you want
