	Component (Actor *pOwner, int pUpdateOrder=100)
	Constructor for Component.
virtual	~Component ()
virtual void	OnStart ()
	Called when the component is initialized (during actor start). This can be used to perform any setup operations for the component.
virtual void	OnEnd ()
	Called when the component is about to be destroyed (during actor destruction). This can be used to clean up or release any resources.
virtual void	OnUpdateWorldTrandform ()
	Called when the world transform of the actor is updated. This allows the component to react to changes in the actor's world transform.
void	SetActive (bool isActive)
	Sets the active status of the component.
void	SetOwner (Actor *pOwner)
	Sets the actor that owns this component.
int	GetUpdateOrder () const
	Returns the update order of the component. Components with lower update orders are updated first.
Actor *	GetOwner () const
	Returns the actor that owns this component.

Public Attributes
Vector3	mGravityDirection = Vector3::Zero

Member Function Documentation

AddForce()

void MoveComponent::AddForce

(

Vector3

pForce

)

Adds a force to the actor's velocity.

Parameters

pForce

The force to add to the velocity.

CheckCollision()

ColliderComponent * MoveComponent::CheckCollision

(

)

Checks for a collision with other colliders in the scene. If a collision is detected, applies a simple collision response.

Returns

The collider component that was collided with, or nullptr if no collision.

GetDesiredPos()

Vector3 MoveComponent::GetDesiredPos ( )

virtual

Computes the desired position of the actor after applying speed and velocity. Also handles collision detection along the X, Y, and Z axes.

Returns

The calculated desired position after checking for collisions.

GetRotationSpeed()

Vector2 MoveComponent::GetRotationSpeed

(

)

const

Gets the current rotation speed of the actor.

Returns

The actor's rotation speed as a Vector2 (x for yaw, y for pitch).

GetSpeed()

Vector3 MoveComponent::GetSpeed

(

)

const

Gets the current speed of the actor.

Returns

The actor's speed in 3D space as a Vector3.

SetCollider()

void MoveComponent::SetCollider

(

ColliderComponent *

pCollider

)

Parameters

pCollider

Collider component to be used for collision checks.

SetRotationSpeed()

void MoveComponent::SetRotationSpeed
