Help about paremeeters and events

[violet karma]

Im tryna learn scripting from Roblox docs but im at this
local trap = script.Parent

local function onTouch(objectTouched)
print("Something touched the trap")
end

-- Connect the function to the Touched event
trap.Touched:Connect(onTouch)
And im learning parameters and events but i do not understand why local function and why trap.tuched:connect(onTuch)

[fresh lark]

Local defines it as local scope

[violet karma]

But i still dont quite understsnd what a Scope is

So I like to think of local as defining what this (in this case trap) is for this specific script. So in this scenario
Local trap = script.parent means that in this script when you use the phrase "trap" and whatever other code after it. The script knows you are talking about the part this script is in. Or the "Parent" of the script

So with trap.touched:connect(onTouch)
It's saying, "Hey. If the parent of this script (trap) gets touched by something then do this function (ontouch)" .

Just my own little explanation of it. Not entirely helpful and may be wrong in some places, thats on me so take it with a grain or two of salt . but it's my way of understanding local and allat jazz so I thought I'd share

[violet karma]

Tysm bro it rlly helped also i understand it now but i feel like in the future im gonna forget the :touched:connect

[worthy lion]

Yeahhh it's rough sometimes with so many coding things to remember lol. That's why sometimes with confusing script parameters I put notes by them the first time around so if I look for a way to do something complex from before I have documented ways of how that code works. Personally I just like to try thinking of everything in the simplest manner.

It also comes naturally so don't sweat it. The more you play with these different codes the more you get to know em better ^_^

[violet karma]

Thanks man also idk but i tried learning from tutorials before and did not go the best each episode was like 30+ min and i got bored so im learning from Roblox documents and i already learned alot more but its harder to learn from there and more complex 🙂

[worthy lion]

Well it's like weighing the pros and cons. Shorter videos are less informative and more to the point but you risk not understanding the topics full nature. But the documents are absolutely the numero Uno In getting what you need to know

[violet karma]

Yeah also one last thing and imma try figuring it out myself i forgot why do i write smth in the box after this

[worthy lion]

Like I just recently figured out how tween stuff works 😭

[violet karma]

😅 im just a qurious guy ig

[worthy lion]

When I look at functions like that I always considered that parentheses to be what contains the parameters. But it doesn't make sense there at least not to me so idrk. I think I'm in the same boat 😭

[violet karma]

I found it out

It was the name of the parameter they used it to destroy whatever touched it look

[worthy lion]

OHHH YEAH

[sterile dagger]

** You are now Level 4! **

[worthy lion]

I use that for hitbox codes

[violet karma]

Yh i just found out its not a kill brick bcuz it doesnt set health to 0 but if my arm for example tuches it its gone

[sterile dagger]

** You are now Level 9! **

[worthy lion]

Like hitbox.touched:connect(function(hit)

Crazy but it clicked

[violet karma]

Ok so lemme try and explain this script of what i learned so far hitbox is probably something before in the script with local hitbox = ....
And .touched is when someone s tuches it and :connect is to connect the touched event with function hit but i dont understand function hit

[worthy lion]

Right I can share my code that might help you see the reason hit its there better

[violet karma]

Yeah

[violet karma]

Ok wth 😭😭

Im over stimulating

[worthy lion]

So this is the whole function train used for making your opponent go silly if you hit them

[violet karma]

Lol so it plays a animation when they are hit right

[worthy lion]

Yessir

[violet karma]

Ok thats probaly the i ly of the code i understood

I started to learn scripting yesterday lol but im at Parameters practice - buttons in Roblox docs so thats probaly gonna be fun

[worthy lion]

So think of the player as a group of parts. A skeleton really. Hit becomes identified as the part that touched the hitbox

We need to generalize that back to character

So we do hit.parent

And THEN that's where we can get the humanoid and everything else we need for some awesome shenanigans

[violet karma]

Dont quite understsnd it still but i understand it better than before

[worthy lion]

Yes please don't pay any mind to the rest of that hocus pocus that's extra stuff just to get a sound and animation to play

[violet karma]

Rn in Roblox docs im learning to like make a button that turns green when stepped on and make a bridge collision=true i think so

[worthy lion]

Ooo that's a fun one

That uses tween service or doesn't and just uses script to make a instant change

[violet karma]

Yeah and hopefully of what ive learned il be able to add in a sound effect too for extra work to get better

[worthy lion]

Sound stuff is pretty easy to get down after you figure out the fundamentals I believe in ya lad

We don't talk abt roll off types and allat tho

Not even I know that yet

[violet karma]

Its maybe gonna be a little bit harder bcuz it starts with transparency 0.5 too and i havent tried changing 2 properties in 1 function or yk what i mean

[worthy lion]

If you wanna change multiple properties at once tween service might be the way to go.

Trust me it looks scary but once you get it you'll be soaring through it

Tweens can change any property you can think of on a part. Even position I believe

Like I have my name in my credits set to constantly change colors using tweens

[violet karma]

Oh my they gave me this bridge.CanCollide = true and told me to try and do the rest myself 😭😭

[worthy lion]

😭

Practice makes perfect ig loll

[violet karma]

But cant do right now im on a phone but what if i try and write it in here and u tell me if it looks right or not

[worthy lion]

Sure works for me ^_^ I got roblox studio open on my game rn anyways so I can run it through

You wanna try to jump the gun and try out tween service? If you get it down it'll make changing colors and sizes during a game a lot easier on ya

[violet karma]

Ok so this script is inside a brick thats works as the bridge

[worthy lion]

If not I understand either way I'll happily oblige

[worthy lion]

OK ok

No fancy drawbridge or nothing just like a block between a gap right?

Trying to imagine it 😭

[violet karma]

Local bridge = script.parent

Local function onTuch(TuchedBridge)

Oh my im brain dead

I cant remember anymore 😭

Ooh my days it wasnt even supposed to go into the bridge it was supposed to go into the button

[worthy lion]

Also just sending this to ya for future reference I noted what stuff does in most of this

Most as in 1 third 😭

[violet karma]

Wait local button = script.parent
Local bridge = workspace.bridge
Local function

And thats all i remember

[worthy lion]

Hmmm seems right up to that point yeah

Remember to connect the function when the button is touched

[vernal shell]

any sufficiently advanced code is indistinguishable from magic

[worthy lion]

And since you wanna make it to where the bridge can collide so you can walk across you can do something like this

Local Bridge = workspace.bridge
Local button = script.parent

Local function(OnTouch)
Bridge.CanCollide = true
)
button.touched:Connect(OnTouch)

I think I'm not too sure

[worthy lion]

Ikr. They finna call me gandalf when I finally start understanding ts

[worthy lion]

Now bear with me here. If you wanted it to change BACK to no collision you can sneak in a little
wait(2)
Bridge.CanCollide = false
into the function >:)

I forgot I have tables to figure out 😭 I got locked in on the side quest

[fresh lark]

Cro became a script ranker
