If the player does not have any open trinket slots, this function will do nothing.
If the player has an open trinket slot but already has a trinket, the new trinket will go to the first slot and the existing trinket will get pushed back to the second slot.
If you provide an argument of 0 or an otherwise invalid trinket ID, the game will crash.
Setting FirstTimePickingUp to false will not spawn or add pickups for the item and will not cause it to count towards transformations.

Add·Wisp ()⚓︎

EntityFamiliar AddWisp ( CollectibleType Collectible, Vector Position, boolean AdjustOrbitLayer = false, boolean DontUpdate = false )⚓︎

The type of Wisp can be defined with the Collectible. If the ID is not corresponding to an active item with a special wisp, it will default to the regular blue wisp.

To access special wisp variant like Delirious forms, you need to add 65536 (1 << 16) to the id. Example: Delirious Monstro has id = s14, so the wisps id is 65550.

Change·Player·Type ()⚓︎

void ChangePlayerType ( PlayerType PlayerType )⚓︎

Used to change one player into another player type. For example turning Cain into Maggy.

Changing the player type within MC_POST_PLAYER_INIT will result in the player getting the default items for that character. E.g. Maggy will get her Yum Heart without you having to explicitly add it. Exceptions here include unlockable items (e.g. Isaac's D6) and default numbers of hearts/keys/bombs/coins. You can change the player type after init, but then you're generally responsible for adding any items you might associate with that character.

Changing the player Type into Jacob will also spawn Esau.

Check·Familiar ()⚓︎

void CheckFamiliar ( int FamiliarVariant, int TargetCount, RNG rng, ItemConfigItem SourceItemConfigItem = nil, int FamiliarSubType = -1 )⚓︎

Call this method to spawn the appropriate amount of familiars associated with a custom collectible.

If the target count specified is less than the current amount of familiars, it will spawn more until the target count is met.
If the target count specified is than the current amount of familiars, it will despawn familiars until the target count is met.

This is meant to be called in the EvaluateCache callback (when the cache flag is equal to CacheFlag.CACHE_FAMILIARS).

Note that this function is bugged in that it will not increment the provided RNG. This is bad because if you provide the player's collectible RNG as the argument for rng, the resulting spawned familiars will potentially have the same InitSeed as familiars spawned previously on the same run. Since InitSeed is the main way to identiy unique familiars, it is important that each familiar has a unique InitSeed. Thus, a brand new RNG object should always be passed to the EntityPlayer.CheckFamiliar method so that each new spawned familiar will have a new, random InitSeed. Subsequently, you should handle random familiar events not with an RNG object based on the familiar's InitSeed, but with a data structure that maps familiar InitSeedto RNG objects that are initialized based on the seed from the EntityPlayer.GetCollectibleRNG method.

In most cases, IsaacScript users should use the checkFamiliarFromCollectibles helper function instead of using this method directly, as it automatically calculates the appropriate target count.

FamiliarVariant: In most cases, use the familiar variant for your custom familiar.

TargetCount: The expected amount of this FamiliarVariant that this EntityPlayer should have. This argument can simply be how many of an item that the current EntityPlayer owns. However, if you want your familiar to synergize with Monster Manual and Box of Friends, then this argument should be EntityPlayer:GetCollectibleNum(collectibleType) + EntityPlayer:GetEffects():GetCollectibleEffectNum(collectibleType).

rng: Always use a brand new RNG object. (See the previous explanation on why you should not use the RNG from the EntityPlayer.GetCollectibleRNG method.)

SourceItemConfigItem: The ItemConfigItem that this familiar was created by. This is nil by default, but it should always be specified so that Sacrificial Altar will work properly. (It informs the game which collectible should be removed if the familiar is tagged with the "cansacrifice" entity tag.) This can be obtained with: Isaac.GetItemConfig():GetCollectible(collectibleType)

FamiliarSubType: The subtype of the familiar to check. -1 matches any subtype.

Example Code

This code spawns 3 "Sister Maggy" familiars.

local player = Isaac.GetPlayer()
local sourceCollectibleID = CollectibleType.COLLECTIBLE_SAD_ONION
local collectibleRNG = player:GetCollectibleRNG(sourceCollectibleID)
local itemConfig = Isaac.GetItemConfig():GetCollectible(sourceCollectibleID)

player:CheckFamiliar(FamiliarVariant.SISTER_MAGGY, 3, collectibleRNG, itemConfig)

Drop·Trinket ()⚓︎

void DropTrinket ( Vector DropPos, boolean ReplaceTick )⚓︎

Evaluate·Items ()⚓︎

void EvaluateItems ( )⚓︎

Triggers a cache reevaluation. Will trigger the MC_EVALUATE_CACHE callback.

Before you use this function, you need to set the appropriate cache flags first. See the example below.

Example Code

This code re-evaluates all of the stats for the player.

local player = Isaac.GetPlayer()
player:AddCacheFlags(CacheFlag.CACHE_ALL)
player:EvaluateItems()

Fire·Bomb ()⚓︎

EntityBomb FireBomb ( Vector Position, Vector Velocity, Entity Source = nil )⚓︎

CanBeEye: If the player has the Evil Eye item, passing true allows the tear to have a chance of being an eye.
NoTractorBeam: If the player has the Tractor Beam item, passing true means that the tear will be exempt from the beam.
CanTriggerStreakEnd: If the player has the Dead Eye item, passing false means that the tear will be exempt from ending the streak.

Fire·Tech·Laser ()⚓︎

EntityLaser FireTechLaser ( Vector Position, LaserOffset OffsetID, Vector Direction, boolean LeftEye, boolean OneHit = false, Entity Source = nil, float DamageMultiplier = 1 )⚓︎

Bugs

The DamageMultiplier parameter doesn't do anything when supplying LASER_TECH2_OFFSET as the offset.

Entity GetActiveWeaponEntity ( )⚓︎

Get·Aim·Direction ()⚓︎

const Vector GetAimDirection ( )⚓︎

Get·Baby·Skin ()⚓︎

Get the current charge progress of the second charge of your current active item. This bar is only active, when you have the Collectible "The Battery"

Get·Black·Hearts ()⚓︎

int GetBlackHearts ( )⚓︎

This does not return the number of black hearts; it returns the bit mask for which soul hearts are black hearts.

Example

Imagine we have the following setup of hearts, where S is a soul heart and B is a black heart:

1	`B S S B B S S B B`

Calling the function will return:

Isaac.GetPlayer():GetBlackHearts() -- returns 409, which is 0001 1001 1001 in binary. Therefore, the read order is right to left.

Get·Bone·Hearts ()⚓︎

int GetBoneHearts ( )⚓︎

Returns the amount of bone hearts that the player has. This is not doubled like the EntityPlayer.GetMaxHearts method is, so if e.g. the player has 3 bone hearts, this will return 3.

Also see the EntityPlayer.GetEffectiveMaxHearts method, which accounts for bone hearts.

Get·Broken·Hearts ()⚓︎

int GetBrokenHearts ( )⚓︎

Returns the amount of broken hearts that the player has. This is not doubled like the EntityPlayer.GetMaxHearts method is, so if e.g. the player has 3 broken hearts, this will return 3.

Variables⚓︎

Baby·Skin⚓︎

BabySubType BabySkin⚓︎

P2 Skin section Used to hold the selected skin (in case of glitched baby it will pick a random one)

Bugs

Move·Speed⚓︎

float MoveSpeed⚓︎

Player stat - Only change this in a callback to MC_EVALUATE_CACHE. This is equal to the Speed Stat. How fast can the player move?

Queued·Item⚓︎

QueueItemData QueuedItem⚓︎

When Isaac picks up a collectible or a trinket, he holds it above his head for a while. At this point, the collectible/trinket is not actually put into his inventory yet.
In other words, the item is queued for insertion until the animation completes, at which point the queue is processed and the item is inserted.
QueuedItem holds a object of type QueueItemData that describes the item that a player is currently holding above their head.
QueuedItem is never nil, even if the player is not currently holding up any item. (However, player.QueuedItem.Item will be nil if they are not currently holding up any item.)
This only stores data for collectibles and trinkets. It does not store any data for pocket items (even though Isaac plays a similar "holding above head" animation for pocket items).
Also see FlushQueueItem(), IsItemQueueEmpty(), and QueueItem().

Internally used by Tainted Samson, increases based on damage dealt, range is 0-100000
