Functions
void	updateParentCollider (const unsigned int &id)
	Updates the collider of a parent mesh.
void	updateCollider (const unsigned int &id)
	Updates the collider of the given entity. If this entity is a parent entity (an entity with a ParentComponent), it will call systems::collision::updateParentCollider() instead.
void	updateAllColliders ()
	Updates all the entities collider by calling systems::collision::updateCollider().
ColliderType	getColliderType (const unsigned int &id)
	Retrieves the type of the entity collider.
void	updateColliderType (const unsigned int &id, const ColliderType &type)
	Updates the collider type of the given entity.
void	updateSimulated (const unsigned int &id, const bool &simulated)
	Updates the simulation of the entity in a PhysicWorld.
void	compressBoundingBox ()
	This method optimize children bounding box of all parent entities in a single square/cube bounding box.
Pair< glm::vec3 >	getCollider (const unsigned int &id)
	Retrieves the collider corners of the entity given.
bool	isColliding (const unsigned int &first, const unsigned int &second)
	Calculate if two entities are colliding or not.
std::vector< Pair< unsigned int > >	getCollisions ()
	Retrieves all entities overlapping each other using simple AABB detection.

Function Documentation

getCollider()

Pair< glm::vec3 > systems::collision::getCollider

(

const unsigned int &

id

)

Retrieves the collider corners of the entity given.

Parameters

id	the entity id

Returns

a pair of (botLeft, topRight) corner

getColliderType()

ColliderType systems::collision::getColliderType

(

const unsigned int &

id

)

Retrieves the type of the entity collider.

Parameters

id	the entity id

Returns

the collider type

getCollisions()

std::vector< Pair< unsigned int > > systems::collision::getCollisions

(

)

Retrieves all entities overlapping each other using simple AABB detection.

Returns

a std::vector<Pair<unsigned int>> containing all overlapping entities

isColliding()

bool systems::collision::isColliding	(	const unsigned int &	first,
		const unsigned int &	second )

Calculate if two entities are colliding or not.

Parameters

first	the first entity id
second	the second entity id

Returns

true if the two entities are colliding

updateCollider()

void systems::collision::updateCollider

(

const unsigned int &

id

)

Updates the collider of the given entity. If this entity is a parent entity (an entity with a ParentComponent), it will call systems::collision::updateParentCollider() instead.

In the other case it will normally update the collider using an Optimized Bounding Box.

ColliderComponent

Parameters

id	the entity id

updateColliderType()

void systems::collision::updateColliderType	(	const unsigned int &	id,
		const ColliderType &	type )

Updates the collider type of the given entity.

Parameters

id	the entity id
type	the collider type

updateParentCollider()

void systems::collision::updateParentCollider

(

const unsigned int &

id

)

Updates the collider of a parent mesh.

Note

This method only updates the collider of the father entity and not his children.

Parameters

id	the parent entity id

updateSimulated()

void systems::collision::updateSimulated	(	const unsigned int &	id,
		const bool &	simulated )

Updates the simulation of the entity in a PhysicWorld.

Note

If an entity is not simulated means that it's a static entity.

Parameters

id	the entity id
simulated	if true the entity is simulated
