Wheel Collider

[little atlas]

@ocean fiber

its just a white screen

its refusing to write to the video buffer

im attempting to reopen

[ocean fiber]

:\

[little atlas]

it finally decided to write to the video buffer

and not just be a completely white window

alright

what do we start off with here

what screenshots from where do you want to begin with

[ocean fiber]

just unity

and yur model

[little atlas]

well i have blender open too just in fucking case

[ocean fiber]

then show wheel colliders

after too

[little atlas]

we have said tank (the axis STILL wont properly align idk why)

then said wheel with still semi-fucked up axis

[ocean fiber]

screenshot the whole scene no cropping

including toolbar of scene

[little atlas]

alright sure

dont mind my taskbar

factorio told it no

[ocean fiber]

only thing change pivot from center to pivot

otherwise, the wheels dont go on the mesh

[little atlas]

where the hell is that

[little atlas]

oh

alright

so what now to fix my fuckin wheel

[ocean fiber]

put a rigidbody

• box collider

[little atlas]

i already have a rigidbody on the main object

why would i put one on the wheel, it wouldnt allow me to put a mesh collider onto it

[ocean fiber]

dont put meshes on wheel

those go separate

all you need to do is have the rigidbody point the correc way

[little atlas]

dont put mesh colliders on the wheels?

[ocean fiber]

the direction of the wheels

https://docs.unity3d.com/Manual/WheelColliderTutorial.html

[little atlas]

and the wheel is fixed

why did no one tell me that before

and why did that not work before

thanks for the help

because no one even suggested that

no im not kidding

[ocean fiber]

np. not sure, there's mixed guides all over

[little atlas]

alright

one last question

is there any way to have unity use a camera similar to blender

[ocean fiber]

what would that be ?

you probably wont be able to change anything functionality wise in terms of orbiting scene cam and how to do all that

just shortcuts for certain things

[little atlas]

instead of the camera pivoting around itself

it pivot around a point

i hate the unity camera

with a burning passion

also

now theres a new issue

and its kinda funny

i dont think i have like any good way to show you other than streaming tho

because of the stupidly low file size limit for videos

nvm

its 100mb bc boost

[ocean fiber]

alr

[little atlas]

im too lazy to figure out fuckin gamebar

lmao

or to open obs

[ocean fiber]

show rigidbody setting

[little atlas]

the default settings

[ocean fiber]

gotta bump that mass to over 2000

[little atlas]

oh

what unit is mass in

KG?

G?

LB?

[ocean fiber]

kg

[little atlas]

holy shit

[ocean fiber]

1kg car doesn't make sense

[little atlas]

thats the wheel

a 2000kg wheel doesnt make sense-

oh wait ik whats happening

the rest of the tank doesnt have colliders

[ocean fiber]

ur supposed to do it on the main rigidbody not thee wheel

and a main box collider on tank

i said that earlier

[little atlas]

what

no the tank is getting a mesh collider and you didnt specifiy where to put those

the tank already has a main rigidbody

[ocean fiber]

rigidbody needs a collider

[little atlas]

well

[little atlas]

yes

but

you didnt specify where

[little atlas]

and so I assummed the wheels as thats what we were talking about, and putting a rigidbody on the wheels fixed that

the tank has had a rigidbody the entire time

[ocean fiber]

wheel need no rigidbody

[little atlas]

well then they face wrong direction

[ocean fiber]

u just need collider on main box collider

then you have to make ur box collider face the right direction

look at the gif above

[little atlas]

what if i want a mesh collider

it needs to work with a mesh collider on the tank

[ocean fiber]

you dont use a mesh coollider for the main chassy rb

[little atlas]

the main chassis RB is the entire asset

because then its an armature

which then every mesh is parented to a bone within that armature

[ocean fiber]

all this is irrelevant to the vehicle rigidbody

[little atlas]

how is the vehicle having a collider irrelevant to the vehicles collision

[ocean fiber]

because you would simplify the colliders to be primitives

using mesh collider is shite optimization and rigidbody doesn't like mesh collider unless convex

[little atlas]

no actually rigidbodies dont like convex mesh colliders

it must be kinematic if its convex

[little atlas]

what if i need collision based upon the actual tanks mesh and not a box around it

[ocean fiber]

pretty sure i've used the engine long enough to know thats not true

[ocean fiber]

for depends on the purpose

also the main rigidbody chassis can still have children colliders

[little atlas]

nice box collider

[little atlas]

well for my version of unity, that is true

i could not have a non-kinematic rigidbody and a convex mesh collider on the same game object

[ocean fiber]

perhaps watch a couple of videos on how to make vehicles specifically tanks

[little atlas]

watching videos is the bane of my existence

[ocean fiber]

when I did , it works fine

[little atlas]

well cool

why does unity have to be so painful

[ocean fiber]

🤷‍♂️ put enough time to learn it and itwont be

[little atlas]

unity is supposed to be easy and simple to learn

that is bullshit then

if i spend hours, on a fucking wheel

[little atlas]

also ive tried looking for tank track videos on youtube

they are all ancient

and are like all overcomplicated

[ocean fiber]

sounds like you want everything easy

[little atlas]

and arnt even like tuctorials

[little atlas]

i want things to not be complete shit and unintuitive

there is no reason

a fucking wheel

should be this hard

[ocean fiber]

could be user skill issue

[little atlas]

"user skill issue"

cool

great

why does anybody use skill issue anymore

it is the most annoying way anybody can say user error

have a nice day.

[ocean fiber]

I guess todays generation want everything handed to them with no effort

🫡

[little atlas]

stop assuming, I don’t want that

That’s absolutely fucking horrible

I want it to make logical sense

And not be absolutely horrible to work with

and have no help

Because everything I find is years old

[ocean fiber]

Well the logic thing is to put in the time to research your issues

[little atlas]

This is the same with blender

[little atlas]

That doesn’t work

google

Is the worst search engine

every time I google some issue with Unity or blender

They give me horribly out of date results

That are completely different major versions of what I’m using

When I google blender shot

*shit

[ocean fiber]

works fine for me, we must be in different year zones

[little atlas]

All I get is versions from the 2000’s and early 2010’s

[little atlas]

it’s not just me

This happens to like most programmers I know

Like actual programmers, not script kiddies

[ocean fiber]

okay right
