Javascript Gacha System

Source code for gacha system with entirely customizable drop rate for each item.

How To Use

1. Create a variable that list your items' data and drop rate.
   You could see the template on the index.js file (itemList variable).
   Make sure you assign the drop rate on the rate property and the item data on the data property.
2. Call the function gacha with the item list on the first parameter.
   It should look something like: gacha(itemList).
   It will return one random item data based on the assigned drop rate.
3. If you need to list the item drop rate, you could use rateListing.
   It should look something like: rateListing(itemList, 3).
   Where 3 is the number of digit after the comma (example: 44.950%).

Notes

If the drop rate is less or more than 100, the system will calculate it automatically. So you don't have to worry if the gacha result will return nothing.
