+/**
+ * A better* version of Minecraft's [net.minecraft.world.entity.ai.Brain] system that makes development more
+ * straightforward and allows easier debugging.
+ *
+ * We could name this thing better.
+ *
+ * There are three main principles inside this system:
+ *
+ * 1: Senses
+ *
+ * Senses are simple ticking objects that are instantiated per entity and are expected to just update memories based
+ * on properties about the entity or its surroundings. This is an analogue of SensorType from Brains.
+ *
+ * 2: Objectives
+ *
+ * Objectives are also ticking objects that are instantiated per entity. They represent a goal for the entity and
+ * run in a fixed order.
+ *
+ * 3: Fixations
+ *
+ * Fixations are a task that can be set on the brain that represents a more total commitment to a certain task. Only
+ * a single fixation can be active at a time, and they can be 'distracted' by other objectives or potentially external
+ * factors.
+ *
+ * These can also be debugged using the /debugcobblemonai command while looking at a Pokémon or NPC entity.
+ *
+ * *that remains to be seen
