Eventing a mining system can be done a number of ways, but making the mining system efficient is a different story altogether. Here is one of the many ways you can tackle a mining system for your RPG Maker project!

You can grab the copy/paste code here:

For those who would like to get the code used for the script call, copy and paste the code here. Change the values in red to fit your game’s settings.

// This is the item ID set by variable 1.
var itemId = $gameVariables.value(1);

// Get the item that uses the item ID.
var item = $dataItems[itemId]; 

// Get the total number of items mined.
var total = $gameVariables.value(2);

// Grant the party the total number of items.
$gameParty.gainItem(item, total);

For those who would like to see how the events are structured from the video, look below!
