Checking For Duplicates In A Table.

[mcd1992]

How would I check if there are two of the same values in one table.

[lua]
for k, v in pairs(soundBlockList) do
for x, y in pairs(soundBlockList) do
if v == y then
table.remove(soundBlockList, x)
end
end
end
[/lua]
It sees and deletes itself :/

Try also checking if the key is different. So if the the values are the same, then check if the keys are the same. if not table.remove
[lua]
for k, v in pairs(soundBlockList) do
for x, y in pairs(soundBlockList) do
if v == y && k != x then
table.remove(soundBlockList, x)
end
end
end
[/lua]

Looks like you're doing a list of blocked sounds. In this case, you better store the sound as the key, and anything you want as the value.

So instead of doing this:

[lua]soundBlockList[1] = sound[/lua]

You do that:

[lua]soundBlockList[sound] = true[/lua]

This way, you are sure there will never be duplicates, and if you ever need to verify if a sound is blocked, all you have to do is check if soundBlockList[sound] is true, instead of iterating through the whole table.
