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]].
