Functions describe an operation that the mod will perform when trying to start a horde, or spawn horde waves.

Spawn Event functions are applied when an entity is spawned in a horde. They are not compatible with spawnevent functions, and need to be in seperate files from those functions.

{	
	"function": "hordes:set_entity_type",
	"value": "minecraft:phantom",
	"conditions": [{
		"name": "hordes:comparison",
		"value": {
			"type": "int",
			"operation": ">=",
			"value1": {
				"name": "hordes:player_pos",
				"value": "y"
			},
			"value2": 100
		}
	}]
}

hordes:set_entity_type changes the type of entity spawned in a horde event from one to another.

In the given example horde entities will be changed into a phantom if the player's y level is above 100 blocks.

{
	"function": "hordes:set_entity_nbt",
	"value": "{HandItems:[{id:stone_sword,Count:1}]}",
	"conditions": []
}

hordes:set_entity_nbt modifies the nbt of entities before they spawn.

The above example gives a stone sword to entities spawned.

{	
	"function": "hordes:set_entity_y",
	"value": {
		"name": "hordes:player_pos",
		"value": "y"
	},
	"conditions": []
}}]
}

hordes:set_entity_x, hordes:set_entity_y and hordes:set_entity_z all work identically, setting the spawn ccordinates of spawned entities.

The above example sets the entities spawn position to the players y value.

{
	"function": "set_entity_loot_table",
	"value": "minecraft:chests/stronghold_library",
	"conditions": []
}

hordes:set_entity_loot_table sets the loot table of spawned entities.

The above example makes entities drop stronghold library loot.
