How to make a disappearing brick handler

DelnRDev · February 23, 2020, 5:46am

i am making a obby game so there is a lots of brick thats need to script .if you just put the script in all the brick that will be lag. so i want to make a handler for it . for the example like disappearing brick i want to put all the disappearing brick in a folder , and make a handler for all the disappearing brick. (i want the brick to if a player touch the brick it will disappear) so how do i script the handler

Personally, I would iterate through all the bricks in the folder and give each of them a function that fires on .Touched. I’ll check if it was a player that touched it and then destroy the brick. If you want the brick to completely vanish I would use :Destroy, but if you want it to stay, just change it’s transparency to 1 and switch CanCollide to false (or just reparent the brick to somewhere like serverstorage and reparent it to workspace)

Alright, there is some misconceptions here on what will cause lag. But what your asking for is easy.

Make a folder and place them all in it.

In script get all decedents of that folder
Do a for loop and do an IsA(“Part”)
Check
When it finds a valid grab that part and you can connect a function to the touched event to kill the brick

You have some options here, you can move the brick to make it disappear, you can destroy it. Or set transparency to 1 and set it to not collide. So that will be up to you.

When you say handler, you may be referring to an event handler and in that case when you do the for loop you need to fire an event in response that passes the part ref with it and you can process outcome elsewhere if you ao please

In my opinion, the best solution would be the Collection Service.

Here is info.

CS is a good service indeed. I would agree that is another option, but takes a touch to get used too.

Since you need a 3rd party plugin to pretag, otherwise you have script go through all the parts and tag them at runtime

starmaq · February 23, 2020, 10:41am

Yeah, but really it doesn’t require a lot of learning, you just need to know two essential methods, :AddTag() and :GetTagged(), and using the plugin doesn’t even need instructions really

You can achieve this by putting the script in serverscriptservice and doing one of the following:

Iterate through the folder’s children containing the parts

for i, v in pairs(Folder_With_Parts:GetChildren()) do
--Code here
end

You can also use “Collection Service”, You add tags to the items you want affected by using :AddTag() or by using a plugin such as Sweetheartichoke’s Tag Editor and add the Tags from there. You then proceed to iterate through the items using the :GetTagged() Syntax as shown:

local parts = game:GetService("CollectionService"):GetTagged("DissapearingBricks")
for i, v in pairs(parts) do
--Code here
end

In addition, Don’t forget to add a Debounce when the touch event is fired as to not cause any lag:

local parts = game:GetService("CollectionService"):GetTagged("DissapearingBricks")
local db = false

for i, v in pairs(parts) do
v.Touched:Connect(function()
if db == false then
db = true
--code here
end
end)
end

Good to mention the ‘debounce’, but your code example is slightly wrong, as it:

does not set the db variable back to false (or maybe it is intentional?),
only has one debounce variable that is used for all bricks’ touch-event.

(BTW: Please use indentation when writing code, as it helps to understand the structure of the code.)

To give each individual brick a ‘debounce’-indicator, then perhaps a dictionary could be used, where the key is the brick-object itself:

local parts = game:GetService("CollectionService"):GetTagged("DisappearingBricks")
local bricksDebounce = {}
for i, v in ipairs(parts) do
  v.Touched:Connect(function()
    if not bricksDebounce[v] then
      bricksDebounce[v] = true
      -- code here
      bricksDebounce[v] = nil
    end
  end)
end

Though depending on what XxAwesomeDabxX means with “disappearing”, if it is supposed to be instantaneous or perhaps just fade away, then the touch-event (and debounce) could be changed, into something like:

local rbxConnections = {}
local function RemoveConnection(part)
  if rbxConnections[part] then
    rbxConnections[part]:Disconnect()
    rbxConnections[part] = nil
  end
end

local TweenService = game:GetService("TweenService")
local function MakePartDisappear(part)
  -- Fade away within 1 second, then destroy the part
  local tweenInfo = TweenInfo.new(1.0)
  local tween = TweenService:Create(part, tweenInfo, { Transparency = 1 })
  tween.Completed:Connect(function()
    part:Destroy()
  end)
  tween:Play()
end

local parts = game:GetService("CollectionService"):GetTagged("DisappearingBricks")
for _,v in ipairs(parts) do
  if v:IsA("BasePart") then
    rbxConnections[v] = v.Touched:Connect(function(hit)
      RemoveConnection(v)
      MakePartDisappear(v)
    end)
  end
end

is there any easier way cuz this is too advance i dont understand

olivesrbx · February 23, 2020, 1:04pm

Here’s an easy one.

while true do
wait(0.1)
for i,v in pairs (folder_with_the_parts_in_it) do
v.Touched:Connect(function(hit)
local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
if plr then
wait(2)
v.Transparency = 1
v.CanCollide = false
wait(2)
v.Transparency = 0
v.CanCollide = true
end
end)
end
end

Although, it’s not the best performance.

DelnRDev · February 23, 2020, 1:14pm

why its said [ServerScriptService.Script:5: bad argument #1 to ‘pairs’ (table expected, got Object)]

olivesrbx · February 23, 2020, 1:16pm

oh whoops, heres fixed code

while true do
wait(0.1)
for i,v in pairs (folder_with_the_parts_in_it:GetChildren()) do
v.Touched:Connect(function(hit)
local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
if plr then
wait(2)
v.Transparency = 1
v.CanCollide = false
wait(2)
v.Transparency = 0
v.CanCollide = true
end
end)
end
end

You have to put :GetChildren() at the end

DelnRDev · February 23, 2020, 1:18pm

umm why have to wait 0.1 at first

olivesrbx · February 23, 2020, 1:19pm

so your game doesn’t crash lol

Decker004 · February 23, 2020, 1:20pm

Take your time to read the code. Even though it might “seem advanced”, if you ‘slow down’ and read it, line by line, statement by statement, it is no different from what others suggest of code.

And do use the Roblox Engine API Reference | Documentation - Roblox Creator Hub to search for the things you do not yet know how works.

olivesrbx · February 23, 2020, 1:21pm

Yeah, roblox teaches you how to code.

olivesrbx · February 23, 2020, 1:21pm

Or search on youtube, theres many ways.

DelnRDev · February 23, 2020, 1:25pm

yeah but its really hard to understand

DelnRDev · February 23, 2020, 1:26pm

i learn basic scripting from copying games

DelnRDev · February 23, 2020, 1:36pm

lol im stupid so i use this
local folder = workspace:FindFirstChild(“Folder”)

while true do

wait()

for i,v in pairs (folder:GetChildren()) do

v.Touched:Connect(function(hit)

local plr = game.Players:GetPlayerFromCharacter(hit.Parent)

if plr then

v.Transparency = 0.1

wait(0.1)

v.Transparency = 0.2

wait(0.1)

v.Transparency = 0.3

wait(0.1)

v.Transparency = 0.4

wait(0.1)

v.Transparency = 0.5

wait(0.1)

v.Transparency = 0.6

wait(0.1)

v.Transparency = 0.7

wait(0.1)

v.Transparency = 0.8

wait(0.1)

v.Transparency = 0.9

wait(0.1)

v.Transparency = 1

v.CanCollide = false

wait(2)

v.CanCollide = true

v.Transparency = 0.9

wait(0.1)

v.Transparency = 0.8

wait(0.1)

v.Transparency = 0.7

wait(0.1)

v.Transparency = 0.6

wait(0.1)

v.Transparency = 0.5

wait(0.1)

v.Transparency = 0.4

wait(0.1)

v.Transparency = 0.3

wait(0.1)

v.Transparency = 0.2

wait(0.1)

v.Transparency = 0.1

wait(0.1)

v.Transparency = 0

end

end)

end
