HitModifiers	GetIncomingStrikeModifiers (DamageClass damageType, int hitDirection, bool ignoreArmorDebuffs=false)
	Initializes a T:Terraria.NPC.HitModifiers calculation with the properties of this NPC, including calling M:Terraria.ModLoader.NPCLoader.ModifyIncomingHit(Terraria.NPC,Terraria.NPC.HitModifiers@)
HitInfo	CalculateHitInfo (int damage, int hitDirection, bool crit=false, float knockBack=0f, DamageClass damageType=null, bool damageVariation=false, float luck=0f)
	Runs M:Terraria.ModLoader.NPCLoader.ModifyIncomingHit(Terraria.NPC,Terraria.NPC.HitModifiers@) hooks and and does the full damage calculations. The result P:Terraria.NPC.HitInfo.Damage will contain the health the NPC will lose when applied.
int	SimpleStrikeNPC (int damage, int hitDirection, bool crit=false, float knockBack=0f, DamageClass damageType=null, bool damageVariation=false, float luck=0f, bool noPlayerInteraction=false)
	Calls M:Terraria.NPC.CalculateHitInfo(System.Int32,System.Int32,System.Boolean,System.Single,Terraria.ModLoader.DamageClass,System.Boolean,System.Single), M:Terraria.NPC.StrikeNPC(Terraria.NPC.HitInfo,System.Boolean,System.Boolean) and then M:Terraria.NetMessage.SendStrikeNPC(Terraria.NPC,Terraria.NPC.HitInfo@,System.Int32) (in multiplayer)
void	StrikeInstantKill ()
	Helper method for calling M:Terraria.NPC.StrikeNPC(Terraria.NPC.HitInfo,System.Boolean,System.Boolean) with a F:Terraria.NPC.HitInfo.InstantKill strike. Use to butcher your own NPCs. Not recommended for use on multiplayer clients because the net packet will trigger M:Terraria.NPC.PlayerInteraction(System.Int32) on the server.
int	StrikeNPC (HitInfo hit, bool fromNet=false, bool noPlayerInteraction=false)
	Directly deals damage to the NPC, spawns combat text, plays hit sound, deals knockback based on the provided T:Terraria.NPC.HitInfo Calls M:Terraria.NPC.HitEffect(Terraria.NPC.HitInfo) and associated hooks after dealing damage. Calls M:Terraria.NPC.checkDead Does not automatically send packets. Use M:Terraria.NetMessage.SendStrikeNPC(Terraria.NPC,Terraria.NPC.HitInfo@,System.Int32) to synchronize hits.
void	HitEffect (int hitDirection=0, double dmg=10.0, bool? instantKill=null)
void	HitEffect (HitInfo hit)
int	FindBuffIndex (int type)
void	AddBuff (int type, int time, bool quiet=false)
	Gives this NPC the provided buff. This accounts for if the NPC is immune to the buff. If the NPC already has the buff, the re-apply logic will happen. Vanilla buff types are found in T:Terraria.ID.BuffID and modded buffs are typically retrieved using M:Terraria.ModLoader.ModContent.BuffType``1. The quiet parameter will determine if the network sync message should happen. This should always stay false.
void	RequestBuffRemoval (int buffTypeToRemove)
	Removes the buff type and shuffles the remaining buff indexes down to fill the gap. Note that only buffs contained in F:Terraria.ID.BuffID.Sets.CanBeRemovedByNetMessage can be removed with this method. The intention is that those specific buffs are "owned" by the player who inflicts them, so they can be freely removed by multiplayer clients. In all other cases code running on the server or in single player is in charge of the NPC debuffs and M:Terraria.NPC.DelBuff(System.Int32) should be used directly.
void	DelBuff (int buffIndex)
	Removes the buff at the provided index and shuffles the remaining buff indexes down to fill the gap. The buff types and times will then be synced to clients. This method should only be called on the server or in single player.

int	GetPartyHatGore ()
	Returns the gore type of the party hat this NPC is currently wearing. If the NPC isn't wearing a party hat, 0 is returned.
void	BecomeImmuneTo (int buffType)
	Adjusts F:Terraria.NPC.buffImmune to make this NPC immune to the provided buff as well as all other buffs that inherit the immunity of that buff (via F:Terraria.ID.BuffID.Sets.GrantImmunityWith). This method can be followed by M:Terraria.NPC.ClearImmuneToBuffs(System.Boolean@) if the NPC should clear any buff it currently has that it is now immune to.

	Spawns an NPC into the game world with the given type. This method should not be called on multiplayer clients. The X and Y parameters dictate the centered spawn position. >ai0, ai1, ai2, ai3 will initialize the NPC.ai[] array with the supplied values. This can be used to pass in information to the NPC. The NPC AI code will have to be written to utilize those values.

static bool	CheckCatchNPC (NPC npc, Rectangle catchToolRectangle, Item item, Player player, bool lavaProofTool=false)
	Runs most code related to the process of checking whether or not an NPC can be caught. After that, M:Terraria.ModLoader.CombinedHooks.OnCatchNPC(Terraria.Player,Terraria.NPC,Terraria.Item,System.Boolean) is run, followed by the code responsible for catching the NPC if applicable. You will need to call this manually if you want to make an NPC-catching tool which acts differently from vanilla's, such as one that uses a projectile instead of an item. As a note, if calling this manually, you will need to check npc.active && npc.catchItem > 0 yourself.

Vector2	netOffset = Vector2.Zero
int	catchItem
	The numerical ID of the item that this NPC becomes when caught. Mainly used for critters that can be caught with bug nets, such as butterflies and worms. Bug nets and other catching tools will only work on NPCs with this field set to something greater than 0.
short	releaseOwner = 255
	Identifies the player who released this NPC into the world. Used mainly for released critters. Helps limit how many critters a player can release. Default to 255, indicating that the npc was not released by a player.
int	rarity
	How rare the NPC is for the Lifeform Analyzer. For example: 4 is for Tim and Mimics, 1 is for bound town NPCs. Defaults to 0.
bool[]	playerInteraction = new bool[256]
	Tracks which T:Terraria.Players have damaged this NPC. Damaging boss minions or other parts of a boss is usually counted as damaging the main body of the boss. Used to determine which players participated in a boss fight and should receive a boss bag. Indexed by each players F:Terraria.Entity.whoAmI (or F:Terraria.Main.myPlayer for code running locally). F:Terraria.NPC.lastInteraction tracks which player was the last player to damage this NPC. M:Terraria.NPC.AnyInteractions can be used to easily check if any player has damaged the NPC.
int	lastInteraction = 255
	The F:Terraria.Entity.whoAmI of the T:Terraria.Player that last damaged this NPC. Used to award Banner items to the player that killed the NPC, but can be used for many other effects. The default value is 255. If the value is 255, the NPC has not been damaged by any T:Terraria.Player. The F:Terraria.NPC.playerInteraction array tracks all players that have damaged this NPC.
float	takenDamageMultiplier = 1f
float	gfxOffY
	An offset from the actual position of the npc that will be added to the draw position. Used to fake the effect of NPC smoothly traveling up single block obstacles.
float	stepSpeed
	Has nothing to do with the speed that this NPC travels, that is dictated by AI code adjusting F:Terraria.Entity.velocity.

Vector2[]	oldPos = (Vector2[])(object)new Vector2[10]
float[]	oldRot = new float[10]
bool	setFrameSize
int	netSkip
bool	netAlways
int	realLife = -1
	Stores the index (the F:Terraria.Entity.whoAmI) of a single NPC. This NPC will then share a health pool with that NPC. Used for the Destroyer's various segments and the Wall of Flesh's eyes and mouth. This is useful for worm enemies. All the segments will point to the same npc, usually the "head" of the npc, and the head and all other non-multi-part NPCs will have the default value of -1 still. Defaults to -1.
float	npcSlots = 1f
	Represents how much this npc counts towards the npc spawn limit. Small critters like worms or flies have values around 0.1f and 0.25f. Enemies that are more difficult than normal have values higher than 1f, and bosses and mini bosses have values around 6. Proper npcSlots values help balance the game and prevents the player from randomly being overwhelmed by powerful enemies. The Spawn rates section on the NPC spawning wiki pagelists vanilla npcSlots values. Use this as a guide to find a suitable value. Defaults to 1f.
float	shimmerTransparency

int[]	buffType = new int[maxBuffs]
int[]	buffTime = new int[maxBuffs]
bool[]	buffImmune = new bool[BuffLoader.BuffCount]
	Contains the NPC buff immunities for this NPC. The default values in this array are populated from F:Terraria.ID.NPCID.Sets.ImmuneToAllBuffs, F:Terraria.ID.NPCID.Sets.ImmuneToRegularBuffs, F:Terraria.ID.NPCID.Sets.SpecificDebuffImmunity, and F:Terraria.ID.BuffID.Sets.GrantImmunityWith.

int[]	immune = new int[256]
	This determines if an NPC can be hit by a item or projectile owned by a particular player (it is an array, each slot corresponds to different players (whoAmI)). It is decremented towards 0 every update. Melee items set immune[Player.whoAmI] to Player.itemAnimation, which starts at item.useAnimation and decrements towards 0. Penetrating projectiles usually set immune to 10, while non-penetrating projectiles do not set immune. ExamplePiercingProjectile.csexplains more about options for npc and projectile immunity.
int	directionY = 1
int	type
	The NPC ID of this NPC. The NPC ID is a unique number assigned to each NPC loaded into the game. This will be equal to either an T:Terraria.ID.NPCID entry or M:Terraria.ModLoader.ModContent.NPCType``1, for example F:Terraria.ID.NPCID.AngryBones or ModContent.NPCType<MyModNPC>(). To check if an NPC instance is a specific NPC, check NPC.type == NPCID.VanillaNPCHere or NPC.type == ModContent.NPCType<ModdedNPCHere>() in an if statement.
float[]	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].
float[]	localAI = new float[maxAI]
	Acts like F:Terraria.NPC.ai, but does not sync to the server. Many vanilla T:Terraria.ID.NPCAIStyleID use these slots for various purposes. Defaults to [0, 0, 0, 0].
int	aiAction
int	aiStyle
	Selects which vanilla code to use for the AI method. Vanilla NPC AI styles are enumerated in the T:Terraria.ID.NPCAIStyleID class. Modders can use vanilla aiStyle and optionally P:Terraria.ModLoader.ModNPC.AIType to mimic AI code already in the game. This is usually only useful as a prototyping tool since it is difficult to customize existing aiStyle code. See P:Terraria.ModLoader.ModNPC.AIType and PartyZombieto see how to use vanilla ai. If you are using custom AI code, there is no need to set this field. Customizing an existing aiStyle usually requires following the Vanilla Code Adaption Guide. If you are using completely custom AI, set this to -1 since an aiStyle of 0 will face the player automatically, which may interfere with your logic. Defaults to 0.
bool	justHit
int	timeLeft
int	target = -1
int	damage
	The amount of contact damage this NPC deals. Changing this WILL NOT change the amount of damage done by projectiles. Usually damage is scaled by some factor when NPC spawn projectiles with Projectile.NewProjectile in AI code. For example, passing in (int)(NPC.damage * 0.5f) as the Damage parameter. The List of NPCs wiki pagecan be useful for finding appropriate values.
int	defense
	How resistant to damage this NPC is. The List of NPCs wiki pagecan be useful for finding appropriate values.
int	defDamage
	Stores the value of F:Terraria.NPC.damage at the end of SetDefaults. Useful for scaling damage in AI code conditionally.
int	defDefense
	Stores the value of F:Terraria.NPC.defense at the end of SetDefaults. Useful for scaling defense in AI code, like how King Slime changes defense as it gets smaller.
bool	coldDamage
	Denotes whether or not this NPC counts as dealing cold damage for the purposes of the Warmth Potion. Defaults to false.
bool	trapImmune
SoundStyle?	HitSound
	The sound that plays when this npc is hit. Set this to an existing T:Terraria.ID.SoundID entry or assign to a new T:Terraria.Audio.SoundStyle for a custom sound. The Basic Sounds Guideteaches how to find existing sounds to use, how to use custom sounds, and how to customize the playback properties of the sounds. For example NPC.HitSound = SoundID.NPCHit1; can be used for the typical NPC hit sound. Defaults to null.
SoundStyle?	DeathSound
	The sound that plays when this npc dies. Set this to an existing T:Terraria.ID.SoundID entry or assign to a new T:Terraria.Audio.SoundStyle for a custom sound. The Basic Sounds Guideteaches how to find existing sounds to use, how to use custom sounds, and how to customize the playback properties of the sounds. For example NPC.DeathSound = SoundID.NPCDeath1; can be used for the typical NPC kill sound. Defaults to null.
int	life
	The current life of the NPC. Automatically set to the value of F:Terraria.NPC.lifeMax at the end of SetDefaults.
int	lifeMax
	The maximum life of this NPC.

Color	color
int	alpha
	0 is opaque, and 255 is transparent. Note that this is the opposite of how alpha is typically expressed in computer graphics. Can be used to fade an NPC in and out. Use P:Terraria.NPC.Opacity instead for a 0f to 1f scaling that uses the high value for fully opaque, as is more typical in computer graphics. Defaults to 0.
bool	hide
	Indicates that this NPC is drawn at a specific layer in the render order. Must use in conjunction with M:Terraria.ModLoader.ModNPC.DrawBehind(System.Int32). See ExampleDrawBehindNPCfor examples of how to use this and all available layers to draw in.
float	scale = 1f
	Makes the NPC bigger or smaller. Bigger than 1f is bigger. Defaults to 1f.

bool	netUpdate
bool	netUpdate2
bool	collideX
bool	collideY
bool	boss
	Set to true if the NPC is a boss. Prevents off-screen despawn. Bosses also need [AutoloadBossHead] annotated on the ModNPC class itself to fully register as a boss.
int	spriteDirection = -1
bool	behindTiles
	Indicates that this NPC draws behind solid tiles. See ExampleDrawBehindNPCfor examples of how to use this and other options for layers to draw in.

bool	SupportsNPCTargets [get]
int	TranslatedTargetIndex [get]
int	WhoAmIToTargettingIndex [get]
bool	IsShimmerVariant [get]
string	TypeName [get]
	The TYPE name of this NPC. Type names are the base titles given to any NPC, and are typically shared amongst all instances of an NPC. For example, the Stylist's type name will always be "Stylist". To modify the type name of a specific NPC, make use of the ModifyTypeName hooks in T:Terraria.ModLoader.GlobalNPC and T:Terraria.ModLoader.ModNPC, according to your needs.
string	FullName [get]
	The FULL name of this NPC. If the NPC doesn't have a given name, this will just return the type name. A Stylist without a given name will always return "Stylist" here. If the NPC does have a given name, this will return the NPC's full name; given name first, then type name. Full name with a given name is given in the format of "X the Y", where X is their given name and Y is their type name. For example, a Stylist might return "Scarlett the Stylist" here; with Scarlett being her given name, and Stylist being her type name.
bool	HasGivenName [get]
	Whether or not this NPC has a given name.
string	GivenOrTypeName [get]
	If this NPC has a given name, returns their given name; otherwise, returns their type name.
string	GivenName [get, set]
	The GIVEN name of this NPC. Can be set directly. Given names are unique to each NPC, though two NPCs can have the same given name. Some vanilla examples of given names are Andrew (for the Guide), Yorai (for the Princess), Whitney (for the Steampunker), or Scarlett (for the Stylist).

bool	SuperArmor [get, set]
	Helper property for defense >= 9999. Extremely high defense is interpreted as 'super armor' where attacks will only do 1 damage (or 2 for crits), no matter how strong they are. Passed to P:Terraria.NPC.HitModifiers.SuperArmor when doing damage calculations. See the docs there for more info. The only way to bypass super armor is to call M:Terraria.NPC.StrikeNPC(Terraria.NPC.HitInfo,System.Boolean,System.Boolean), or set NPC life directly.
bool	HideStrikeDamage [get, set]
	If true, damage combat text will not be shown by M:Terraria.NPC.StrikeNPC(Terraria.NPC.HitInfo,System.Boolean,System.Boolean) and dps meter will not record damage against this NPC. Recommended for use with F:Terraria.NPC.immortal
IBigProgressBar	BossBar [get, set]
	Assign a special boss bar, vanilla or modded. Not used by vanilla.
float	gravity [get, private set]
	The current change in velocity due to gravity applied every frame. Multiply F:Terraria.NPC.GravityMultiplier to modify this value.
float	maxFallSpeed [get, private set]
	The current fall speed cap in velocity applied every frame. Multiply F:Terraria.NPC.MaxFallSpeedMultiplier to modify this value.
static float[]	GravityWetMultipliers [get]
	The effect of different liquids on NPC gravity. Provided for reference only, modifying these will have no effect. Corresponds with wet, lavaWet, honetWet, and shimmerWet.
static float[]	MaxFallSpeedWetMultipliers = new float[4] { 0.7f, 0.7f, 0.4f, 0.55f } [get]
