Public Member Functions
void	updateCollider (const std::vector< glm::vec3 > &coords, const glm::mat4 &model)
	This method updates the collider cornders coords by iterating over all mesh vertices. It will find the minimum and the maximum corner in World Space Coordinates, the corresponding vertex coords are the new bottom left and top right corners.
void	updateCollider (const glm::vec3 &position, const glm::vec3 &size)
	This method update a non Optimized Bounding Box by summing the given size with the given position. This kind of update is generally used for colliders where doesn't matter the precision of collision detection.

	Checks if the given collider is overlapping with the current one.

Detailed Description

Component to store mesh collider data to solve collision in a PhysicWorld.

Note

It is also possible to use a default system of collision detection integrated with ECS systems, it uses a simple AABB detection.

Constructor & Destructor Documentation

ColliderComponent()

ColliderComponent::ColliderComponent ( const glm::vec3 & position, const glm::vec3 & size )

inline

Instances a non Optimized Bounding Box collider.

Parameters

position	collider center position
size	collider size (center-right)

Member Function Documentation

isColliding()

bool ColliderComponent::isColliding ( const ColliderComponent & other ) const

inline

Checks if the given collider is overlapping with the current one.

Parameters

other

collider of the other mesh

Returns

true if other and this colliders are overlapping

updateCollider() [1/2]

void ColliderComponent::updateCollider ( const glm::vec3 & position, const glm::vec3 & size )

inline

This method update a non Optimized Bounding Box by summing the given size with the given position. This kind of update is generally used for colliders where doesn't matter the precision of collision detection.

Parameters

position	collider center position
size	collider size

See also

ColliderComponent::size

updateCollider() [2/2]

void ColliderComponent::updateCollider ( const std::vector< glm::vec3 > & coords, const glm::mat4 & model )

inline

This method updates the collider cornders coords by iterating over all mesh vertices. It will find the minimum and the maximum corner in World Space Coordinates, the corresponding vertex coords are the new bottom left and top right corners.

Note

This is also called in this project: Optimized Bounding Box. This means that the collider "perfectly" contains the mesh in the most efficient single square.

size

glm::vec3 ColliderComponent::size {}

collider size

Note

It need to follow the projection: in case the projection is ortho the size should be different from perspective projection.
