isAliveExceptionNPC
▸ isAliveExceptionNPC(npc): boolean
Checks for specific NPCs that have "CanShutDoors" set to true naturally by the game, but should not actually keep the doors closed (like Death's scythes).
Parameters
| Name | Type |
|---|---|
npc | EntityNPC |
Returns
boolean

isDaddyLongLegsChildStompEntity
▸ isDaddyLongLegsChildStompEntity(npc): boolean
Helper function to distinguish between a normal Daddy Long Legs / Triachnid and the child entity that is spawned when the boss does the multi-stomp attack.
When this attack occurs, four extra copies of Daddy Long Legs will be spawned with the same
entity type, variant, and sub-type. The Entity.Parent field will be undefined in this case, so
the way to tell them apart is to check for a non-undefined Entity.SpawnerEntity field.
Parameters
| Name | Type |
|---|---|
npc | EntityNPC |
Returns
boolean

isDyingDump
▸ isDyingDump(npc): boolean
Helper function to detect the custom death state of a Dump. When Dumps die, they go to
NPCState.SPECIAL, spit out their head, and then slowly fade away while shooting a burst of
tears.
Parameters
| Name | Type |
|---|---|
npc | EntityNPC |
Returns
boolean

packages/isaacscript-common/src/functions/npcs.ts:132
isDyingEggyWithNoSpidersLeft
▸ isDyingEggyWithNoSpidersLeft(npc): boolean
Helper function to detect the custom death state of an Eggy. Eggies are never actually marked dead by the game. Instead, when Eggies take fatal damage, they go into NPCState.STATE_SUICIDE and spawn 14 Swarm Spiders while their StateFrame ticks upwards.
Parameters
| Name | Type |
|---|---|
npc | EntityNPC |
Returns
boolean
Defined in
packages/isaacscript-common/src/functions/npcs.ts:145
isRaglingDeathPatch
▸ isRaglingDeathPatch(npc): boolean
Helper function to detect the custom death state of a Rag Man Ragling. When Rag Man Raglings die, they turn into a patch on the ground and can be revived by Rag Man at a later time. This causes them to show up as an "alive" enemy, so they should usually be filtered out of lists of alive enemies.
Parameters
| Name | Type |
|---|---|
npc | EntityNPC |
Returns
boolean
