Public Member Functions
	RectangleColliderComponent (Actor *pOwner)
	Constructor for RectangleColliderComponent.
void	DebugRender (IRenderer *pRenderer) override
	Renders the rectangle as a line in the world for debugging purposes.
Rectangle	GetWorldRectangle () const
	Gets the world-space rectangle based on the owner's position. Transforms the local-space rectangle to its global position.
bool	Collision (const Rectangle &otherRectangle)
	Checks for collision with another rectangle in world space.
bool	Collision (const ColliderComponent *pComponent) override
	Checks for collision with another collider component. Only supports collision with other RectangleColliderComponent instances.
Public Member Functions inherited from ColliderComponent
	ColliderComponent (Actor *pOwner)
	Constructor for ColliderComponent.
void	OnStart () override
	Called when the component starts. Registers the component for debug rendering and adds it to the physics system.
void	OnEnd () override
	Called when the component ends. Unregisters the component from debug rendering and removes it from the physics system.
Public Member Functions inherited from Component
	Component (Actor *pOwner, int pUpdateOrder=100)
	Constructor for Component.
virtual	~Component ()
virtual void	Update ()
	Called every frame to update the component. This can be used to perform actions that need to be updated periodically.
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
Rectangle	mRectangle { Vector2(-16,-16),Vector2(32,32) }
	Checks Local-space rectangle defining the collider shape.
Public Attributes inherited from ColliderComponent
Color	mColor { 255,0,0,255 }
	Debug rendering color for the collider (default: red).

Additional Inherited Members

Detailed Description

RectangleColliderComponent represents a 2D axis-aligned bounding box (AABB) collider. It provides collision detection and debug rendering for rectangular shapes in 2D space.

Constructor & Destructor Documentation

RectangleColliderComponent()

RectangleColliderComponent::RectangleColliderComponent

(

Actor *

pOwner

)

Constructor for RectangleColliderComponent.

Parameters

pOwner

The actor that owns this collider component.

Member Function Documentation

Collision() [1/2]

bool RectangleColliderComponent::Collision ( const ColliderComponent * pComponent )

overridevirtual

Checks for collision with another collider component. Only supports collision with other RectangleColliderComponent instances.

Parameters

pComponent

Pointer to the other collider component.

Returns

True if a collision is detected, false otherwise.

Implements ColliderComponent.

Collision() [2/2]

bool RectangleColliderComponent::Collision

(

const Rectangle &

otherRectangle

)

Checks for collision with another rectangle in world space.

Parameters

otherRectangle

The other rectangle to check against.

Returns

True if a collision is detected, false otherwise.

DebugRender()

void RectangleColliderComponent::DebugRender ( IRenderer * pRenderer )

overridevirtual

Renders the rectangle as a line in the world for debugging purposes.

Parameters

pRenderer

The renderer used to draw the debug rectangle.

Implements DebugRenderInterface.

GetWorldRectangle()

Rectangle RectangleColliderComponent::GetWorldRectangle

(

)

const

Gets the world-space rectangle based on the owner's position. Transforms the local-space rectangle to its global position.

Returns

A Rectangle in world-space coordinates.

Member Data Documentation

mRectangle

Rectangle RectangleColliderComponent::mRectangle { Vector2(-16,-16),Vector2(32,32) }

Checks Local-space rectangle defining the collider shape.
