Unity Lifecycle & Setup

Methods

protected override void Start()

Initializes the alien unit with enhanced mobility settings for wall climbing and jumping

protected override void Update()

Updates the alien's behavior including panic-inducing presence that affects nearby enemy units

Position & Physics

Methods

protected override void AnimateActualJumpingFrames()

Animates jumping frames while maintaining proper vertical scale during acrobatic movements

protected override void GetEnemyMovement()

Processes enemy AI movement unless the alien is performing tumbling or somersault maneuvers

protected override void NotPressingJump()

Handles wall climbing state transitions based on directional input when not jumping

Properties

protected override bool WallDrag { get; set; }

Gets or sets wall dragging state with automatic wall climbing activation based on input

Combat & Damage

Methods

public override void Death(float xI, float yI, DamageObject damage)

Handles alien death while ensuring proper sprite scaling is maintained

Parameters:

  • float xI: Horizontal force applied to the corpse
  • float yI: Vertical force applied to the corpse
  • DamageObject damage: The damage object that caused death

protected override void FallDamage(float yI)

Applies fall damage effects based on fall speed and current acrobatic state

Parameters:

  • float yI: The vertical impact velocity (negative values indicate downward motion)

Special Abilities

Methods

protected override bool CanPassThroughBarriers()

Determines that aliens can always pass through barrier blocks

Returns:

  • bool: Always returns true, granting aliens unrestricted barrier passage

public override bool Inseminate(AlienFaceHugger unit, float xForce, float yForce)

Prevents face hugger insemination of alien units

Parameters:

  • AlienFaceHugger unit: The AlienFaceHugger attempting insemination
  • float xForce: Horizontal force component (unused)
  • float yForce: Vertical force component (unused)

Returns:

  • bool: Always returns false, making aliens immune to face hugger attacks

Environmental Interaction

Methods

protected override bool IsAboveLadder()

Determines that aliens never detect ladders below them

Returns:

  • bool: Always returns false, preventing downward ladder detection

protected override bool IsNearbyLadder(float xOffset, float yOffset)

Determines that aliens never detect nearby ladders regardless of position

Parameters:

  • float xOffset: Horizontal offset for proximity check (unused)
  • float yOffset: Vertical offset for proximity check (unused)

Returns:

  • bool: Always returns false, preventing all ladder proximity detection

protected override bool IsOverLadder(float xOffset, ref float ladderXPos)

Determines that aliens never interact with ladders when checking overhead positions

Parameters:

  • float xOffset: Horizontal offset for ladder detection (unused)
  • out float ladderXPos: Output parameter for ladder X position (not set)

Returns:

  • bool: Always returns false, preventing overhead ladder detection

Networking & RPC

Methods

public override UnityStream UnpackState(UnityStream stream)

Deserializes network state and applies death state if the unit was dead

Parameters:

  • UnityStream stream: The network stream containing serialized state data

Returns:

  • UnityStream: The stream after unpacking for potential further processing

Helper & Utility

Fields

protected ActionState lastActionState

Stores the previous action state for state transition detection

protected bool lastWallClimbing

Tracks the previous frame's wall climbing state for transition detection

protected bool lastWallDragging

Tracks the previous frame's wall dragging state for transition detection

private float panicSurroundingMooksDelay

Countdown timer controlling the panic aura effect frequency in seconds
