What is a good way to reverse a table I want to make something like this .

table={1, 2, 3, 4, 5, 6, 7,8 ,9, 10}

to

table={10, 9, 8, 7, 6, 5, 4, 3, 2,1}

thanks for help!

This code copies the content into a new table, reversed.

local lengthOfTable = #myTable for i = 0, lengthOfTable-1 do newTable[#newTable+1] = myTable[lengthOfTable-i] end

On a side note: depending on the type of content, you can use the sort command as well.

#3

First, you should never name a table “table”. There is an object of table manipulation function called “table”.

As for the code:

local newTable = {} for i = #oldTable, 1, -1 do     newTable[#newTable + 1] = oldTable[i] end

Or something like that.

I just edited my code because it was missing a “+1” somewhere. Better now.

Rob, I think your code doesn’t reverse the order.

#5

You’re right, I updated the code to do reverse order.
