Member Function Documentation

eastl::vector< eastl::weak_ptr< CollisionComponent > > Engine::CollisionSystem::GetActiveCollisionComponents

(

)

const

Gets all of the collision components that are currently active in the world.

Returns

std::vector of weak pointers of collision components

Definition at line 136 of file CollisionSystem.cpp.

bool Engine::CollisionSystem::IsRunning

(

)

const

Returns true if the Collision system is running

Returns

bool that represents wheter or not the collision system is running.

Definition at line 131 of file CollisionSystem.cpp.

eastl::weak_ptr< Entity > Engine::CollisionSystem::RayQueryAllHit	(	const glm::vec2 &	start,
		const glm::vec2 &	end
	)		const

Returns all collision-objects hit by the ray. TODO - Implementation

Parameters

start	The start position of the ray.
end	The end position of the ray.

Returns

vector of shared_ptr of CollisionComponent of all collision-bodies hit by the ray

Definition at line 126 of file CollisionSystem.cpp.

eastl::weak_ptr< Entity > Engine::CollisionSystem::RayQueryFirstHit	(	const glm::vec2 &	start,
		const glm::vec2 &	end,
		CollisionLayer	detectionLayers
	)		const

Returns the first collision-body hit by the ray. TODO - Implementation

Parameters

start	The start position of the ray.
end	The end position of the ray.
detectionLayers	The collision layers you want to use.

Returns

shared_ptr of CollisionComponent of the first collision-body hit by the ray.

Definition at line 109 of file CollisionSystem.cpp.

void Engine::CollisionSystem::Start

(

)

Starts the Collision System, gathering all required component data and generating collision bodies from it. Allows further calls to Update().

Definition at line 65 of file CollisionSystem.cpp.

void Engine::CollisionSystem::Stop

(

)

Stops the Collision System, emptying m_collisionComponents Prevents further calls to Update().

Definition at line 59 of file CollisionSystem.cpp.

void Engine::CollisionSystem::Update

(

)

Updates the collision world. Takes transform data of collision components, changes it, and replaces the old transform data with the new data.

Definition at line 71 of file CollisionSystem.cpp.
