Sggelblob

Based on game build 714014 | Last updated: 2026-03-08

Overview

SGgelblob defines the state machine for the Gelatinous Blob entity, a boss-like creature in DST that can change size, spawn via delay, and respond to damage. It manages animations (including shared back-layer animations), sound effects, shadow scaling, sanity aura effects, and interaction with the health and sanityaura components. It extends common electrocution states and uses timeline/frame events to coordinate timed gameplay effects during transitions.

Usage example

This stategraph is automatically assigned to the gelblob prefab during entity instantiation and is not manually invoked. A typical invocation pattern is handled internally by the engine:

-- internally in the prefab definition (not user-modifiable directly)
inst.entity:AddPhysics()
inst:AddTag("gelblob")
inst:AddStateGraph("gelblob", "SGgelblob")

Dependencies & tags

Components used: health, sanityaura Tags: gelblob, boss, monster, prey

Properties

Property	Type	Default Value	Description
inst.size	string	"_big"	Current size suffix used for animations and sounds ("_big", "_med", "_small"). Managed via state transitions (shrink_*, grow_*).

Main functions

_PlayAnimation(inst, anim, loop)

• Description: Plays an animation on both the main and back AnimState components, appending the entity’s inst.size suffix (e.g., "idle_big").
• Parameters: inst (entity instance), anim (string base animation name), loop (boolean — whether to loop).
• Returns: Nothing.

_PushAnimation(inst, anim, loop)

• Description: Pushes an animation onto the animation queue (non-blocking), appending the entity’s inst.size suffix.
• Parameters: inst (entity instance), anim (string base animation name), loop (boolean).
• Returns: Nothing.

SetShadowScale(inst, scale)

• Description: Adjusts the entity’s dynamic shadow size proportionally using scale, based on in-progress animation frames during spawning or shrinking.
• Parameters: inst (entity instance), scale (number — multiplier for shadow width/height).
• Returns: Nothing.

Events & listeners

• Listens to:
  • "jiggle" (custom event) — triggers jiggle state if not busy/dead and caninterrupt is allowed.
  • "animover" (in spawn, hit, jiggle, spit, shrink_*, grow_* states) — transitions back to idle when animation completes.
  • "onelectrocute", "onattacked", "ondeath" — handled via CommonHandlers.OnElectrocute(), etc., integrated into events list.
• Pushes:
  • "healthdelta" — triggered by health:DoDelta() during electrocution state.
  • "animover" — implicitly fired by the engine when animations complete, then handled by state callbacks.
