Add Entity Attributes Section
After creating and configuring the entity type builder, it must be built. This requires the modid and name of the entity type. For an entity type with the name "example_monster" in the mod "examplemod", this would look like <code>builder.build("examplemod:example_monster")</code>.

To define custom behavior, methods must be overriden. Your IDE should have a feature to list all possible methods to override, although some common ones might be: <code>customServerAiStep</code> for server AI, <code>tick</code> for code to execute each tick on client/server, and <code>registerGoals</code> to setup AI goals.

== Entity Attributes ==
Since 1.17 and later versions, you **MUST** define attributes if your entity class extends <code>LivingEntity</code> or any other class that inherits from it. In Attributes, you can define:
* Max Health
* Movement Speed
* Attack Damage
and more...
In your Entity class, create a static method that creates your attributes:
<code>
// In your Entity class...
public static AttributeSupplier.Builder setAttributes()
{
return createHostileAttributes().add(Attributes.MAX_HEALTH);
}
</code>

To make entities naturally spawn, they must be added to the spawn list for each biome that the entity should spawn in. This can be achieved with a [[Biome Modifiers#Add Spawns|<code>forge:add_spawns</code> biome modifier]].
