Member Function Documentation

pick_nearest() [1/2]

entity::id collision_system::pick_nearest	(	const geom::ray< float, 3 > &	ray,
		std::uint32_t	flags
	)		const

Picks the nearest entity with the specified picking flags that intersects a ray.

Parameters

ray	Picking ray.
flags	Picking flags.

Returns

ID of the picked entity, or entt::null if no entity was picked.

Definition at line 43 of file collision-system.cpp.

pick_nearest() [2/2]

entity::id collision_system::pick_nearest	(	const math::fvec3 &	origin,
		const math::fvec3 &	normal,
		std::uint32_t	flags
	)		const

Picks the nearest entity with the specified picking flags that has a non-negative distance from a plane.

Parameters

origin	Origin of the picking plane.
normal	Picking plane normal direction.
flags	Picking flags.

Returns

ID of the picked entity, or entt::null if no entity was picked.

Definition at line 83 of file collision-system.cpp.

update()

void collision_system::update ( float  t, float  dt  )

virtual

Perform's a system's update() function.

Parameters

t	Total elapsed time, in seconds.
dt	Delta time, in seconds.

Implements updatable_system.
