Sgshadow Bishop

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

Overview​

SGshadow_bishop defines the full state graph for the Shadow Bishop boss, controlling its attack patterns, movement, and transitions. It inherits common states (idle, taunt, hit, death, etc.) from SGshadow_chesspieces and extends them with a multi-phase attack sequence (attack → attack_loop → attack_loop_pst → attack_pst) that includes periodic area-of-effect attacks, invincibility windows, and positional teleports. The state graph handles the entity’s physics, animation, sound, and visual effects synchronization during boss encounters.

Usage example​

This stategraph is instantiated automatically when the Shadow Bishop entity is created and does not require direct manual instantiation by modders. It is registered and used internally by the entity's StateGraph component.

-- Internally, the stategraph is loaded and assigned to the entity via:
inst:AddComponent("stategraph")
inst.components.stategraph:ChangeState("idle")
-- All states and logic are defined in SGshadow_bishop.lua and inherited states from SGshadow_chesspieces.lua

Dependencies & tags​

Components used: combat, health Tags: attack, busy, noattack (applied via state tags during attack phases)

Properties​

No public properties are defined in this stategraph. All state behavior is controlled through internal state logic and inst.sg.statemem for transient state data.

Main functions​

DoSwarmAttack(inst)​

  • Description: Performs an area-of-effect attack around the Shadow Bishop, damaging nearby valid targets within hitrange.
  • Parameters: inst (entity instance) - the Shadow Bishop entity triggering the attack.
  • Returns: Nothing (uses Combat:DoAreaAttack internally).
  • Error states: Does not return any value; failures in DoAreaAttack are silently handled by the component.

DoSwarmFX(inst)​

  • Description: Spawns a shadow_bishop_fx prefab at the Shadow Bishop's position and scales/orients it to match the entity for visual feedback during attacks.
  • Parameters: inst (entity instance) - the Shadow Bishop entity.
  • Returns: Nothing.

Events & listeners​

  • Listens to:
    • animover - triggers state transitions upon animation completion (e.g., advance from pre-attack to loop).
    • All events defined in ShadowChess.CommonEventList (inherited from SGshadow_chesspieces.lua), including hit, death, taunt, etc.
  • Pushes: No events are explicitly pushed by this stategraph; it relies on state transitions and inst.sg:GoToState() for control flow.
