Typedef Documentation

TransformSystem2d

template<typename HTag , typename XTag = HTag>

using entttree::TransformSystem2d = typedef TransformSystem<HTag, double, 2, XTag>

Definition at line 242 of file transform_hierarchy.h.

TransformSystem3d

template<typename HTag , typename XTag = HTag>

using entttree::TransformSystem3d = typedef TransformSystem<HTag, double, 3, XTag>

Function Documentation

add_transforms()

template<typename XTag = void, typename T = double, size_t N = 2, typename HTag >

auto entttree::add_transforms	(	entt::registry &	reg,
		HierarchySystem< HTag > &	hierarchy
	)

Construct a TransformSystem with deduced hierarchy tag and optional overrides.

Easy path: auto xf = add_transforms(reg, hierarchy);

Layered path: auto xf = add_transforms<RenderXf>(reg, hierarchy);

Fully specified: auto xf = add_transforms<RenderXf, float, 3>(reg, hierarchy);

Template Parameters

XTag	Transform-layer tag. Defaults to the hierarchy tag when omitted.
T	Scalar type. Defaults to double.
N	Spatial dimension. Defaults to 2.
HTag	Hierarchy tag (deduced from hierarchy).
