how do you change the transparency of multiple blocks without changing the name?

i made a tool but wanna make it so that all the parts are transparent (don't ask why) how do i do it?

Use the GetChildren method of an object to access a list of the objects inside of it, then iterate through them and change their Transparency.

In addition to iwaffle1's answer, the GetChildren method is a read-only table of the given parent's childrens, For Instance.

local Children = workspace:GetChildren() or game.Workspace:GetChildren()

This not be edited with nor Modified, to iterate through it, you'd have to use a iterating function or the Pairs function, Example of layout.

for index,value in pairs(Children) do
	return v
end

The value in the Pairs is a variable of all the Parent's children, and the index is the Current Index, Example of an Index :

local var = 56

for i,v in pairs(var) do
	print(i,v) --> var 56
end

• Lua

for i = begin,last,increment do

end
