How to handle saving dozens of tiny objects

Questions & Answers
1

I have a lot of mario style coins in each level of my game, and I need a way save when they have been taken by the player. So when you go back to that level later they are gone. There are dozens in each level, so giving them a unique name and saving a PlayerPref string for each is not something I want to do manually.

Whats the best way to go about this?

Hope this helps you.

Pseudocode:

OnCoinPickUp () {

CoinList.Add(coinPickedUp);

}

OnSave () {

for (i = 0; i < CoinList.Count; i++)
{

    for (j = 0; j < TotalCoins.Count; i++)
    {
        if (CoinList*.coin.name == TotalCoins[j])*

{
//1 for True
PlayerPrefs.SetInt(TotalCoins[j].name, 1);
} else {
//Set 0 for False since this coin has not been picked up
if (i == TotalCoins.Count - 1)
PlayerPrefs.SetInt(TotalCoins[j].name, 0);
}
}
}
}
OnCoinsLoad () {
for (i = 0; i < ListOfCoinsInPlayerPrefs; i++)
{
if (ListOfCoinsInPlayerPrefs*.value == 1)*
//Load Coins
else
//Dont load Coins
}
}
