Effort API

1. First, make a effort class to record diamond ores mined.

public class MineDiamond implements EffortEvent {

    @Override
    public EffortType getEventType() {
      /* Event Type is BLOCK_BREAK because we want to check diamond      ores mined */
        return EffortType.BLOCK_BREAK;
    }

    @Override
    public boolean checkPlayer(Event e) {
// Change Event to BlockBreakEvent
        BlockBreakEvent ev = (BlockBreakEvent) e;
 
// Check if the Block Material is a Diamond Ore
      if (ev.getBlock().getType() != XMaterial.DIAMOND_ORE.parseMaterial()) return false;

//Check if block break event is cancelled
        if (ev.isCancelled()) return false;

// Player has broken a diamond ore, return true.
        return true;
    }

    @Override
    public String getEffortID() {
// Put in the ID of the effort.
        return "MINEDIAMOND";
    }

    @Override
    public String getDisplayName() {
// Optional
        return "Diamond Ores Mined";
    }

}

2. Register the Effort Event for the API to start recording

@Override
    public void onEnable() {
// register the Event with EffortAPI.registerEvent on your onEnable()
        EffortAPI.registerEvent(new MineDiamond());
    }

3. You are done! The API will now record diamond ores mined by the players!

4. Now that you are done, lets give players a reward for mining 100 diamond ores by listening to EffortBukkitEvent.java

@EventHandler
    public void giveRewardForMiningDiamond(EffortBukkitEvent e)
    {
        // Check if the id is MINEDIAMOND
        if (e.getEffortEvent().getEffortID().equalsIgnoreCase("MINEDIAMOND")) {
            // Give reward
        }
    }
