Struct let_engine::resources::materials::Material

pub struct Material { /* private fields */ }

A material holding the way an object should be drawn.

It takes some time to make a new material.

Implementations

impl Material

Making

Right now it produces an error when the shaders don’t have a main function.

pub fn new_with_shaders( settings: MaterialSettings, shaders: &Shaders, instanced: bool, writes: Vec<WriteDescriptorSet> ) -> Result<Self, VulkanError>

Creates a new material using the given shaders, settings and write operations.

pub fn new(settings: MaterialSettings) -> Result<Material, VulkanError>

Makes a new default material.

pub fn new_instanced( settings: MaterialSettings ) -> Result<Material, VulkanError>

Makes a new default material.

pub fn new_default_textured(texture: &Texture) -> Material

Creates a simple material made just for showing a texture.

pub fn new_default_textured_instance(texture: &Texture) -> Material

impl Material

pub unsafe fn write( &mut self, descriptor: Vec<WriteDescriptorSet> ) -> Result<()>

Writes to the material changing the variables for the shaders.

Safety

The program will crash in case in case the data input here is not as the shader wants it.

pub fn set_layer(&mut self, id: u32) -> Result<(), TextureError>

Sets the layer of the texture in case it has a texture with layers.

pub fn layer(&self) -> u32

Returns the layer of the texture in case the material is textured.

pub fn next_frame(&mut self) -> Result<(), TextureError>

Goes to the next frame of the texture.

Returns an error if it reached the limit.

pub fn last_frame(&mut self) -> Result<(), TextureError>

Goes back a frame of the texture.

Returns an error if the layer is already on 0.

pub fn texture(&self) -> Option<Texture>

Returns the texture.

pub fn set_texture(&mut self, texture: Option<Texture>)

Sets the texture.

Trait Implementations

impl Clone for Material

fn clone(&self) -> Material

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Material

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Material

fn eq(&self, other: &Material) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
