How do I make a function completely clear a table?
I'd like to be able to make this function clear out the table, or overwrite it instead of adding onto it. How would I go about that? I couldn't just use table.remove(rolls) could I?
sides = 6
numdice = 1
rolls{}
function rollthedice()
for i = 1, numdice do
table.insert(rolls, math.random(1,sides))
end
end

For many purposes, you can just replace the variable with a new empty table:
rolls = {}
This doesn't actually affect the old object, meaning if you had something like this:
local old_rolls = rolls
rolls = {}
print(#old_rolls) --> 5 or whatever
the ones referencing the old table won't be cleared. Normally you shouldn't have that case.
If you have a list, you can repeatedly table.remove from it:
while #rolls > 0 do
table.remove(rolls)
end
