Functionality for entities with a ranged attack. Inherits from BaseEntityController.

Documentation updated 8/26/2024

Author: Roy Pascual

Public Attributes
GameObject	projectilePrefab
	The projectile this entity will shoot.

Protected Member Functions
override void	ActivateAttack ()
	Instantiates a new projectile and flips it to face the right direction.

override void	TriggerAttack ()

override void	CloseAttackState ()

Protected Member Functions inherited from BaseEntityController
void	ActivateAttack ()
	Triggered by an event in the attack animation (or you can override TriggerAttack() if there is not attack animation). This function muse be overridden by any inheriting class.

virtual void	PatrolState ()
	When the entity hasn't detected any enemies...

virtual void	ChaseState ()
	If the entity has detected an enemy...

Additional Inherited Members
Public Member Functions inherited from BaseEntityController
void	ChangeSpeed (float speedChange)
	Speeds up or slows down the entity's movement speed. A negative value for speedChange will slow down the entity.

void	ChangeSpeed (float speedChange, float duration)
	Temporarily speeds up or slows down the entity's movement speed. A negative value for speedChange will slow down the entity.

void	DestroyOnDeath ()
	Can be optionaly run by ObjectHealth.onDeath.

Protected Attributes inherited from BaseEntityController
ObjectHealth	objectHealth
	Reference to the object responsible for managing the player's health.

Transform	attackPoint
	Reference to the entity's attack point. It's a point in space that's a child of the entity, existing some distance in front of it. Projectiles spawn from the attack point, and melee attacks scan for enemies to damage from a certain radius around it.

int	attackDamage = 30
	Amount of damage the entity's attack will deal.

float	attackCooldown = 0.8f
	The amount of time between attacks.

float	cooldownEndTime = 0f
	Amount of time until cooldown is over. Set to the current time + attackCooldown when the attack is triggered.

LayerMask	enemyLayers
	Objects on these layers will be considered an enemy of this entity, and if detected, this entity will seek to attack. An object can be assigned to a layer in the Unity Editor from a drop down menu in the top right.

PatrolZone	patrolZone
	A patrol zone is an object that has two points the entity will walk between if it does not detect an enemy.

float	horizontalDirection = 0f
	Horizontal direction the entity is traveling in.

float	detectionRange = 6f
	How far away the entity will detect an enemy from and start chasing.

float	activateAttackRange = 3f
	How close the entity must be to an enemy to attack it.

float	entityCenter = 1.4f

bool	hostileDetected = false
	True if the entity has detected an enemy.

bool	hostileInCloseRange = false
	True if the entity is close enough to an enemy to attack it.

Rigidbody2D	rb
	Reference to the entity's rigidbody.

float	moveVelocity = 6.0f
	How fast the entity should move.

float	speedModifier = 0f
	The precent of moveVelocity the entity should move at. Used for slowing the entity down.

float	linearDrag = 1.0f
	Amount of drag to apply to the rigidbody.

float	groundedRaycastLength = 1.8f

GroundDetector	groundDetector
	Reference to the entity's GroundDetector.

bool	groundNeeded = true
	Can be set to false to let the entity walk even when it is not on the ground.

bool	canWalk = true
	Used for disabling entity movement.

Animator	animator
	Reference to the entity's animator.

Properties inherited from BaseEntityController
EntityState	EState = EntityState.Patrol `[get, protected set]`
	Current state the entity is in.

Member Function Documentation

◆ ActivateAttack()

override void RangedEntityController.ActivateAttack ( )

protected

Instantiates a new projectile and flips it to face the right direction.

◆ CloseAttackState()

override void RangedEntityController.CloseAttackState ( )

protectedvirtual

Modified from the base version so entity flips direction if target moves behind it

Todo: Make entityCenter offest a variable rather than hard coded.

Reimplemented from BaseEntityController.

◆ TriggerAttack()

override void RangedEntityController.TriggerAttack ( )

protectedvirtual

Plays the attack animation and runs ActivateAttack().

Note: The attack animation for the Seth Follower fires the arrow immediately, so just calling ActivateAttack() immediately is ok.

Reimplemented from BaseEntityController.
