I'm trying to find all of the ClassName SelectionBox in the workspace so I can change their color. However, they all have different Parents and Children so it would be laborious to make a script ....:GetChildren() for all of them.
How can I get All of the Descendants of a said instance such as Workspace?
Don't use recursive functions - Iterative ones are better
function GetDescendants(i)
local queue = {};
local returns = {};
local v = i;
while v do
local t = v:GetChildren();
for i = 1, #t do
local v = t[i]
returns[#returns+1] = v;
queue[#queue+1] = v;
end;
v = queue[#queue];
queue[#queue] = nil;
end;
return returns;
end;
So, you're trying to gather all of the SelectionBoxes in workspace and change their color?
For this, you can use recursion. Recursion is essentially re-iterating a function upon itself. Like if you were to go;
function a()
a()
end
This is recursion. But be wary when using recursion, as you can easily end up with a stack overflow. Stack overflow errors happen when you call a function inside itself too many times within a short amount of time, with no yeild. The code above would give you a stack overflow error.
So, to use recursion to your advantage? You need to make a function that iterates through workspace. This can be done through a generic for loop. Check if the current child is a SelectionBox, and if it is recolor it. Then, you can recall the function on itself with each child.
--'model' being the group to search
--'color' being the color to change the selectionboxes to
function search(model,color)
local function recurse(m,c)
--Iterate through the model
for _,v in next, m:GetChildren() do
--Check if the object matches
if v:IsA("SelectionBox") then
--If so, change the color
v.Color3 = color
end
if #v:GetChildren() > 0 then
--If there are objects left, recurse.
recurse(v,t)
end
end
end
recurse(model,color)
end
Now you can call the function with the specified arguments.
search(workspace,Color3.new(1,0,0))
--Red
NO BAD NO RECURSION BAD GOUL
RECURSION IS YUM THO AND WORKZZ

Wow thanks for this. I don't understand what the ; do though.
