ai

float [] Terraria.NPC.ai = new float[maxAI]

An array with 4 slots used for any sort of data storage, which is occasionally synced from the server to clients. Each vanilla T:Terraria.ID.NPCAIStyleID uses these slots for different purposes. Set F:Terraria.NPC.netUpdate to true to manually sync. The advantage of using these 4 floats is that they are synced automatically. Using fields in your P:Terraria.NPC.ModNPC class will work just the same, but they might need to be synced via M:Terraria.ModLoader.ModNPC.SendExtraAI(System.IO.BinaryWriter) and M:Terraria.ModLoader.ModNPC.ReceiveExtraAI(System.IO.BinaryReader) if necessary.
Clever use of Reference return valuesas seen in ExampleCustomAISlimeNPC.cscan be used to reuse the ai array entries with readable names.
Defaults to the values passed into M:Terraria.NPC.NewNPC(Terraria.DataStructures.IEntitySource,System.Int32,System.Int32,System.Int32,System.Int32,System.Single,System.Single,System.Single,System.Single,System.Int32), usually [0, 0, 0, 0].
