how to reset or clear a table

Hi

I have a table that I add items too during gameplay. How do I reset this when I complete a level

--global or local table for the project

list = {"apple","pear","orange"}

function newLevel ()

list = {} --does this reset the table above or simply create a different local table for the function?

--code here

end

Hmm... dangerous question....

Simple answer is yes.... setting table={} will "clear" or "reset" it but.... if your table includes much more than what you have shown (In Lua a table can contain almost anything) you should take the time to remove the entries/objects within the table in order to free the memory that they use before "clearing/reseting" the table. (destroying the index for the table.)

i always declare all my variables that or not local to a function at the top of my code like this

1
2
3
4
5
6
7
8
9
10
11
12
--functions
local fnNew, fnSetup, fnStart 
--images
local imgBG,imgMan,imgBox
--variables
local score,highscore,level,objects
 
function fnSetup()
    score,highscore,level,objects = 0,0,1,{}
end
 
fnsetup()

If it's global what I usually do when I need to clear it run a loop that removes each value:

1
2
3
for i = 1, #table do
table.remove(table, i)
end

Declaring your variables is a good practice but.... in reguards to tables.... they can contain almost anything... and some things should be removed before you destroy the index that points to it...

hmm...

...
local object = {}
object[1]= display.newimage("sample1.png")
object[2]= display.newimage("sample2.png")
object[3]= display.newimage("sample3.png")
object[4]= display.newimage("sample4.png")
object[5]= display.newimage("sample5.png")
--table with objects in it :)
 
object = {}
--last line did NOT destroy/remove those objects
