timid quartz
There's no decent way in Rust to have a generic integer without using a crate
spare quartz
wdym by generic integer?
timid quartz
How you have type T is range <>
spare quartz
are your generics like
only allowed to be used with types with the same binary size/rep?
timid quartz
Itās not that, itās just that thereās no one āintegerā trait in the rust standard library
Generic constraints are done via traits in rust
timid quartz
Like if you look up the stdlib docs for u32 you can see the sheer number of traits it implements
Thereās a crate that has a Num trait but itās separate from the stdlib
spare quartz
two other interesting tidbits i found while reading the advanced manual;;
- all enumerations are parameterless functions
- types are imaginary; they all resolve to their own sets of 'Base "machine types"
spare quartz
Like if you look up the stdlib docs for u32 you can see the sheer number of trai...
woah
jesus
JESUS
theres hundreds???
timid quartz
Well you can do lots of things with an int
spare quartz
same in ada but like
types themselves don't implement anything
A.B (...);
B isn't actually apart of the type A; it just takes in A as its first parameter
timid quartz
The way it works in Rust is with structs and traits
Classes and interfaces if you prefer to think that way
Since the stdlib needs to be extensible both internally and externally it makes sense that they defined all those traits for a u32
So they could get shared to other integer types and also be used by people to make their own types do different things
timid quartz
Classes and interfaces if you prefer to think that way
Except one difference is you can implement a trait for a struct thatās not yours
spare quartz
Classes and interfaces if you prefer to think that way
i really don't like that sort of implementation honestly
timid quartz
Itās just the rust way of doing things
spare quartz
blanket implementations?
timid quartz
If you want generic constraints or want to share behavior in an interface-like manner, you use traits
timid quartz
blanket implementations?
Not entirely sure what that means
spare quartz
If you want generic constraints or want to share behavior in an interface-like m...
i suppose that is an advantage, yeah
aside from generics in ada you can't.. share functionality to another type (unless its a function that takes in a 'Class of a tagged record)
type A is new Integer; makes A incompatible with Integer
scary
question about your atomics if you can answer; how are they defined in rust?
in ada atomics are values in memory that can be written to in one assembly instruction
(aswell as being "independent" (not sharing its space in memory w/ other objects) and "volatile")
i again learned this from the advanced course (that i should really read more its kinda interesting)
timid quartz
question about your atomics if you can answer; how are they defined in rust?
Not sure, I havenāt looked that deep into it
Iād imagine either one instruction ops or they pause interrupts
spare quartz
Each atomic operation is indivisible with regards to any other atomic operation that involves the same object. Atomic objects are free of data races.
thats the same definition as adas!!! omg!!
spare quartz
i dont knowwhat youre taking abot,,
oh
note for future self dont use atomics/volatiles in threading
:<
timid quartz
With rust you slap a type in the good olā Arc<Mutex<T>>
spare quartz
as far as i know in ada its either a PO (protected object) or a rendezvous
timid quartz
Does Ada have channels?
spare quartz
wdym
timid quartz
Like go-style channels for communicating between threads
I guess that would be rendezvous
spare quartz
a rendezvous is
again as far as i know i dont know much about this section of tasking
a thread waiting to reach a point in another thread thats the "messaging" point
timid quartz
Yeah hence I said it seems like a rendezvous
timid quartz
Damn so Ada might have done it first
Iām sure some people did similar stuff in C first
spare quartz
well duh its C
what havent people done in it

timid quartz
Need a new language like C where nothing you do is incorrect if it fuckin works

mayyyybe zig but probably not as much
timid quartz
timid quartz
But rust gives a compiler error if you do anything off the books

hot take minestom is kind of shit
so now im doing it from scratch again just on a version that doesn't require sending every registry to the client in order to login

Not so fast
Thereās many warnings the compiler will tell you like
Having a type of ānot null accessā in your function and not setting it to something
Itāll compile, but it tells you thisāll raise a Program_Error/Constraint_Error (forgot which) at runtime
timid quartz
Not so fast
Well I took what lucky said to mean āif it compiles it worksā not āI want to dereference a null pointer and not segfaultā
spare quartz
Thatās not what a null pointer is
Itāll crash the moment you load the function because immediately youāre violating the constraint
Not so much that itās a segfault
If you wanted a program with like, basically zero protection against programmer error
Iād sayā¦ JS, Lua, or just downright assembly
Oh and C but thatās a given

would i also have to change line 9 then
spare quartz
to the new variable name yes
odd flint
still doesnt work 
spare quartz
waaaaait
player:GetPlayerFromCharacter(player)
should be
player:GetPlayerFromCharacter(hit.Parent)
because youll need to be getting the character model to get a player
if leaderstats then
local money = leaderstats:FindFirstChild("Money")
if money then
money.Value = money.Value + 1
end
end
and this section of code should go into the if player then chunk of code;; replace "player" to the new name you have for the variable
odd flint
`player:GetPlayerFromCharacter(player)`
should be
`player:GetPlayerFromCharacter...
it was originally like that ill go back to that
so like this?
local player = game:GetService("Players")
local collector = script.Parent
local leaderstats = workspace.Leaderboard
local function onContact(hit)
hit:Destroy()
if hit and hit:IsA("Part") then
local subject = player:GetPlayerFromCharacter(hit.Parent)
if subject then
local leaderstats = player:FindFirstChild("leaderstats")
local money = leaderstats:FindFirstChild("Money")
if money then
money.Value += 1
end
end
end
end
collector.Touched:Connect(onContact)
hit:Destroy() should be done AFTER the if/not done at all
but yeah i think that looks okay
odd flint
it still isnt adding money
could it be cuz its not getting the right info from the other script?
spare quartz
add some prints to the code to see if its getting subject/leaderstats/money properly
odd flint
its never been getting player
ima see if its still doing that
its not getting subject
which is the issue that ive been having the entire time
spare quartz
and just to confirm you moved hit:Destroy() after the if statements
odd flint
yup
spare quartz
weird
odd flint
local player = game:GetService("Players")
local collector = script.Parent
local leaderstats = workspace.Leaderboard
local function onContact(hit)
if hit and hit:IsA("Part") then
local subject = player:GetPlayerFromCharacter(hit.Parent)
if subject then
print("found subject")
local leaderstats = player:FindFirstChild("leaderstats")
local money = leaderstats:FindFirstChild("Money")
if money then
money.Value += 1
hit:Destroy()
end
end
end
end
collector.Touched:Connect(onContact)
this is all correct right
spare quartz
i think so
timid quartz
So normally what actually touches the part (hit) is one of the player's limbs/accessories/etc
Not the player's actual character
So it'll be something like Character.LeftArm or whatever
So you have to do hit.Parent to get the actual character model which is named after the player
Does that make sense @odd flint?
odd flint
that part makes sense but could that be messing up my script since the player never actually touches the part
timid quartz
No
There's a distinction between the "Player" and the "Character"
Both are linked to each other but both live in different areas
The character lives under workspace with all the other models and the player lives under game.Players
odd flint
player is ur data and character is the model?
timid quartz
Which is why, whenever the player's character touches whatever it is that you have, you have to say game:GetService("Players"):GetPlayerFromCharacter(hit.Parent)
To find the actual player object
timid quartz
player is ur data and character is the model?
Yeah basically this
meower beneath me
spare quartz
player is ur data and character is the model?
character is the one in the world
player is the representation for your client being in the server
you don't need a character to be in a game, but you need the player
odd flint
Which is why, whenever the player's character touches whatever it is that you ha...
touches the block thats being spawned?
timid quartz
Yeah
Well wait
oh wait
this is
entirely wrong
this is for when the BLOCK dropped by the DROPPER hits the end of the conveyor right
odd flint
it hits a block at the end
spare quartz
indeed...
timid quartz
hit is the block
spare quartz
okayyy lets come up with a new design then
spare quartz
add an event to the burner thing at the end of the conveyor instead of the block thats being dropped
if the hit part is tagged blah blah blah then destroy it and add an amount to the (player who owns it)'s wallet (probably using an attribute on the dropped part)
if you wanna make the player able to collect the raw parts for money then add an event doing the above described
do note you dont need to clone a whole script for the part to add an event
you can attach an event where the dropped part is created
odd flint
can i just change this part
local subject = player:GetPlayerFromCharacter(hit.Parent)
if subject then
print("found subject")
and leave
local leaderstats = player:FindFirstChild("leaderstats")
local money = leaderstats:FindFirstChild("Money")
if money then
money.Value += 1
hit:Destroy()
or do i need to redo the whole thing
spare quartz
well to do the design i suggested you'd need to change a lot of things
but if the goal here is to..
have a script in the dropped part that adds this event
then instead of "subject" you'd check if the hit part was the collector part, i'd imagine?
and the player to add the money to would be in the collectors attributes?
spare quartz
meower beneath me
odd flint
have a script in the dropped part that adds this event
the script is in the destroy block
timid quartz
yesterday it segfaulted on open, today it is having a "general protection fault" on open
spare quartz
the script is in the destroy block
okay so the script is for the collector part..?
spare quartz
yesterday it segfaulted on open, today it is having a "general protection fault"...
i wanna read into this thing later cause i dont like it initially
also this ramen is boiling me
odd flint
yeah i think so
doing
local collectorPart = workspace.DropperFolder.DropperItemCollector
``` fixed some of iti have to modify more
spare quartz
yeah i think so
okay so if its a collector script check if the hit part is tagged something, and add the amount of money its worth to the player who owns the collector's wallet
spare quartz
alright, where are you creating the dropped parts?
spare quartz
like, can you show me the section of code where the part is created
odd flint
oh yeah
local dropper = workspace.DropperFolder.Dropper
local clickDetector = script.Parent
local function spawnBlock(whenClicked)
local block = Instance.new("Part")
block.BrickColor = BrickColor.Random()
block.Position = dropper.Position
block.Parent = workspace
print("Done")
end
clickDetector.MouseClick:Connect(spawnBlock)
oh good you're not using the second argument of instance.new
alright so before "block.Parent = ..." run this method on the part
tag it whatever you'd like, just something clear to get it across "this is a dropper part"
after that, setattribute something on it to indicate how much its worth - default value... 1?
odd flint
so
local dropper = workspace.DropperFolder.Dropper
local clickDetector = script.Parent
local function spawnBlock(whenClicked)
local block = Instance.new("Part")
block.BrickColor = BrickColor.Random()
block.Position = dropper.Position
block:AddTag(dropper)
block:SetAttribute(1)
block.Parent = workspace
print("Done")
end
clickDetector.MouseClick:Connect(spawnBlock)
this?
spare quartz
you need an argument before the 1 in SetAttribute, the name of the attribute
and the argument in tag must be in "" quotation marks
otherwise itll be a variable, not a string
just a mote of advice: you can add --!strict at the top of your script to see if you've made any potential problems
odd flint
im sorry im trying not to come off as a retard š but it would be like this then right?
block:SetAttribute"value"(1)
if i put value inside of the () then it errors
spare quartz
:SetAttribute("Value", 1)
spare quartz
function "x" is syntaxically equal to function ("x"), but that's only for single argument functions
timid quartz
i wanna read into this thing later cause i dont like it initially

local money = leaderstats:FindFirstChild("money")
local collector = itemValue:GetAttribute("value")
if itemValue then
money.Value += collector
hit:Destroy()
end
end
end
end
collector.Touched:Connect(onContact)
but now im getting an error "Workspace.DropperFolder.DropperItemCollector.ItemCollect/GiveMoney:13: attempt to index nil with 'FindFirstChild'"
spare quartz
you need to get the player who owns the collector
in your code "player" is just a reference to the global players service
odd flint
in line 1?
spare quartz
correct
spare quartz
LocalPlayer is only accessible on the client side, while this should be a server side script
youll need to find some way to put who owns the collector inside the collector's attributes
odd flint
how the script currently works i think anyone can interact with it
regardless of team
i havent gotten far enough to make it team specific
spare quartz
well then i think youll just have to add it to everyone's wallet
spare quartz
to do that youll need to loop over the players in Players
for Index, Player in player:GetPlayers() do ... end
odd flint

@spare quartz can u help me with something again (sorry to bother u again)
spare quartz
?
odd flint
im trying to make a team script for a game
i think the parameters might be wrong but i tried different stuff and same result
wait(5)
local Players = game:GetService("Players")
local Team = game:GetService("Teams")
local teamNeutral = game.Teams.Neutral
local function setTeam(Team)
if Players.Team and Players.Team ~= game.Team["Neutral"] then
Players.Team = game.Team["Neutral"]
else
print("no")
end
end
you should use task.wait instead of wait; wait is deprecated
teamNeutral can be changed to Team.Neutral because Team is a reference to game.Teams
you do not need "Players.Team and" when you are doing a comparison like "Players.Team ~= game.Team["Neutral"]"
finally; "Players" here, is again, a reference to the Players service, and not the player you're possibly talking about
is this a local script or a server script
spare quartz
then you need to run it over every player like you did with the last collector script
look at the loop for details and change "Players" in that function to the secondary loop parameter
odd flint
teamNeutral can be changed to Team.Neutral because Team is a reference to game.T...
like this?
local Team.Neutral = game.Teams.Neutral
when i do it like that it errors

oh oops

wdym it still doesnt work
odd flint
doesnt team
spare quartz
show your code
odd flint
task.wait(1)
local player = game:GetService("Players")
local team = game:GetService("Teams")
local neutralTeam = team.Neutral
local function setTeam(team)
if player.Team ~= game.Team["Neutral"] then
player.Team = game.Team["Neutral"]
else
print("no")
end
end
you're referencing the players service, not an individual player
thats why it doesnt work
i think this is what you're trying to do, right?
task.wait(1)
local Players = game:GetService("Players")
local Teams = game:GetService("Teams")
local neutralTeam = Teams.Neutral
local function setTeam(team)
for _, player in pairs(players:GetPlayers()) do
if player.Team ~= neutralTeam then
player.Team = neutralTeam
else
print("no")
end
end

well yeah but templates can also be a PITA (or so ive heard)
something you have to do is either implement templated stuff entirely where it's defined, or if you wanna do the .hpp/.cpp split, you have to add small little declarations for each type you want it to work for in the .cpp file
end users can also do this themselves
but for example
// whatever.hpp
template<typename T> class Whatever { /* ... */ }
// whatever.cpp
template<typename T>
Whatever<T>::Whatever() { /* ... */ }
//...other implementations
template class Whatever<int>
//...further additions for types

you cannot disable a script while its running
you CAN:

what's the use case of this script
full berry
why do i see a lot of open source code fellas use underscores as variable names
like not even as consts or anything (Talking about the JS/TS universe here), but mostly like inline arrow functions or inline error handling (.catch)
like matter of fact i tried these
.catch(err => console.log())
and
.catch(err => console.log())
For the first one, my editor gave me a warning before it commited that err was an unused variable, but when I used the 2nd example, then there was no error?
odd flint
what's the use case of this script
It stops items from spawning when the player first joins until they turn it on
umbral monolith
like matter of fact i tried these
```ts
.catch(err => console.log())
```
and
```...
those are the same things š
anyway "_" is the discard name
it mutes warnings about unused variable names
and all it needs to do is start with it
so "_err" is muted but is still readable as the error
really basic example: ```ts
function add(a: number, b: number, onAdd: (any, number) => void)
{
onAdd(false, a + b);
}
add(2, 3, (_useless, result) => console.log(2 + 3 = ${result}));
i am not interesting in using the first paramater, but i have to define it if i want to use the second one
giving it a name without _ will bug me about it being unused, so I add it in to mute that

How to Get Help
- Before asking: Try to find the solution yourself. (
CTRL+Fin this specific channel might help you) - Skip "I need help", "Help please", "Can I ask a thing", "I have an error" - It wastes everyone's time. Follow the "How to as a question" guide below.
- This channel can be used to get "help and support", however please take longer sessions out of this channel into DMs.
How to Ask a (Good) Question
- Show your code.
- Show your errors.
- Explain what happens and what you want to happen instead.
- Text is usually better than screenshots. Use code blocks starting with ```lua.
Help Us to Help You
- Run your code before asking if it can work. (errors are often very useful in pin-pointing the issue! )
- Imagine you are the one trying to help. Ask the question in a way that you would want to read!
- Post your full error and the code surrounding that error.
- If you use custom functions in your snippet, show them to us! (we only know how lua works, not how you defined custom functions)
- Actively participate in the "solution-finding" process. (don't expect people to fix the code for you)
- Explain what you tried to do to fix the problem.
- Read the responses you are given.
- Research key words you do not understand before asking what they mean. (come back and ask, if you cannot find them)
No Answer?
- Do not mention uninvolved people to get a response.
- Try to rephrase your question.
- Try to give more context / improve your description.
- Try to find a solution yourself while waiting.

<@516049910622191626> question
how would i disable a script via another script
...
so what i would do (this is extreme even though i do it sometimes) is to create a bindableevent inside one of those scripts, then fire the event whenever you'd like to disable it
then inside the script that you want to disable, you can create a function when the bindable is fired that disables itself:
local bindable = script.BindableEvent
bindable.Event:Connect(function()
script.Enabled = false
end)
this is a bit more of an advanced way to do it but oh well
odd flint
i just ended up disabling the script in studio manually and then enabling it later with a script
ill keep this in mind for the future tho
