Sgwx78 Drone Scout

Based on game build 722832 | Last updated: 2026-05-05

Overview

Stategraph for the WX-78 drone scout entity. Stategraphs are attached via StartStateGraph or inst:StartStateGraph, not called as utility functions. Major state categories: deploy (initialization) and idle (hovering).

Usage example

-- Attach stategraph to entity:
inst:StartStateGraph("wx78_drone_scout")

-- Trigger deploy sequence:
inst.sg:GoToState("deploy")

-- Drone will automatically transition to idle after deploy animation completes

Dependencies & tags

External dependencies:

• None

Components used: None identified

Tags:

• busy -- added in deploy state to block other transitions
• idle -- added in idle state for idle-specific behavior

Properties

State name	Tags	Description
deploy	busy	Initial state for deploying; plays deploy animation and stops physics. At frame 0, plays beep sound.
idle	idle	Hovers in place; loops idle animation.

Main functions

UpdateHover(inst, dt) (local)

• Description: Calculates and sets vertical velocity for sinusoidal hover pattern. Retrieves current position with inst.Transform:GetWorldPosition(), current time value from inst.sg.statemem.t, and motor velocity with inst.Physics:GetMotorVel(). Calculates ht = ht0 + math.sin(t * TWOPI / period) * amp, then sets vertical velocity as (ht - y) * 15. Behavior depends on conditions: if inst:IsAsleep() returns immediately; if t is nil (initial state), handles liftoff conditions; if t < 0, enters liftoff mode. Updates sg.statemem.t with new time value. * Parameters:
  • inst -- entity owning the stategraph
  • dt -- delta time
• Returns: nil
• Error states: None.

onenter (deploy)

• Description: Plays deploy animation, stops physics motion, sets sg.mem.vel to zero, and resets sg.statemem.t to nil.
• Parameters: inst -- entity owning the stategraph
• Returns: nil
• Error states: None.

onupdate (deploy)

• Description: Updates hover position by calling UpdateHover local function.
• Parameters: inst -- entity owning the stategraph
• Returns: nil
• Error states: None.

onenter (idle)

• Description: Plays idle animation in loop and sets sg.statemem.t to the passed t.
• Parameters:
  • inst -- entity owning the stategraph
  • t -- initial time for hover pattern
• Returns: nil
• Error states: None.

onupdate (idle)

• Description: Updates hover position by calling UpdateHover local function.
• Parameters: inst -- entity owning the stategraph
• Returns: nil
• Error states: None.

Events & listeners

Listens to:

• animover (in state deploy) -- triggers transition to idle state when deploy animation completes.

World state watchers: None.

Pushes: None.
