Struct ark_api::render::RenderMeshInstanceBuilder

pub struct RenderMeshInstanceBuilder { /* private fields */ }

Creates RenderMeshInstance through the builder pattern

Implementations

impl RenderMeshInstanceBuilder

pub fn new(mesh: &RenderMesh) -> Self

Creates a new builder from a RenderMesh.

pub fn with_world_transform(&mut self, world_transform: &Mat4) -> &mut Self

Set world transform. Default is Mat4::IDENTITY

pub fn with_style(&mut self, style: &RenderMeshStyle) -> &mut Self

Set the style. Default is RenderMeshStyle::default()

pub fn with_instance_id(&mut self, instance_id: InstanceId) -> &mut Self

Set the instance id. Default is 0 which means no instance id.

pub fn with_materials_offset(&mut self, offset: u32) -> &mut Self

Set the materials offset. Default is 0. This is the offset the instance will use to read into the material overrides provided with Render::draw_meshes_with_materials.

pub fn with_materials_len(&mut self, len: u32) -> &mut Self

Set the materials length. Default is 0.

This is the number of material overrides the instance will use Render::draw_meshes_with_materials. By default it will take all materials after the offset

pub fn with_mesh_styles_index(&mut self, idx: u32) -> &mut Self

Set the materials offset. Default is 0. This is the index of the mesh style in the mesh_style_overrides list passed into Render::draw_meshes_with_materials_and_styles. If the index is not valid in the overrides list it will use the RenderMeshInstance::style variable instead.

pub fn build(&self) -> RenderMeshInstance

Builds the mesh instance
