Class DodgingComponent

java.lang.Object

com.csse3200.game.components.Component

com.csse3200.game.components.npc.DodgingComponent

public class DodgingComponent
extends Component

A component that adds a dodging event listener to the current attached entity. The entity will dodge another entity that is presumably coming at its current position. It will dodge at a certain angle in the vertical direction with an altered speed.

This component handles the detection of a certain mob layer within a certain horizontal range using a raycast. It also handles the vertical speed doding configuration.

Created for the mob entity to dodge incoming projectiles but can be used for other entities and functionalities if needed.

Constructor Details

DodgingComponent

public DodgingComponent(short targetLayer)

Initialises a component that dodges an incoming entity based on its target layer. The range detection is defaultto 0.25f.

Parameters:

targetLayer - The target layer to be detected horizontally.

DodgingComponent

public DodgingComponent(short targetLayer,
 float rangeDetection)

Initialises a component that dodges an incoming entity based on its target layer. This initialisation also sets the range detection whereby the dodge event is triggered.

Parameters:

targetLayer - The target layer to be detected horizontally.

rangeDetection - The range where the entity of the target layer is detected, activating the dodge event.

DodgingComponent

public DodgingComponent(short targetLayer,
 float rangeDetection,
 float dodgeSpeed)

Method Details

create

public void create()

Called when the entity is created and registered. Entity created will have the dodge entity event. Also registers the original speed of the current entity.

Overrides:

create in class Component

changeTraverseDirection

public void changeTraverseDirection(com.badlogic.gdx.math.Vector2 mobPos)

Changes the moving direction of the attached entity with this component.

Relies heavily on the isTargetVisible() method, and setting the vertical angle direction and speed helper methods found in this component class.

Parameters:

mobPos - The current Vector2 mob position in the map.
