# Included in the Mod

The API, above, allows you to register awards
and triggers (things that look for events and unlock awards, they need
to be registered in order to get details from award_def.trigger).

However, all awards and triggers are separate from the API.
They can be found in init.lua and triggers.lua

## Triggers

Callbacks (register a function to be run)

### dig

	trigger = {
		type = "dig",
		node = "default:dirt",
		target = 50
	}

### place

	trigger = {
		type = "place",
		node = "default:dirt",
		target = 50
	}

### death

	trigger = {
		type = "death",
		target = 5
	}

### chat

	trigger = {
		type = "chat",
		target = 100
	}

### join

	trigger = {
		type = "join",
		target = 100
	}
