How to use Vertex

[cherish-ltt]

//! Very simple shader used to demonstrate how to get the world position and pass data
//! between the vertex and fragment shader. Also shows the custom vertex layout.

// First we import everything we need from bevy_pbr
// A 2D shader would be very similar but import from bevy_sprite instead
#import bevy_pbr::{
    mesh_functions,
    view_transformations::position_world_to_clip
}

struct Vertex {
    // This is needed if you are using batching and/or gpu preprocessing
    // It's a built in so you don't need to define it in the vertex layout
    @builtin(instance_index) instance_index: u32,
    // Like we defined for the vertex layout
    // position is at location 0
    @location(0) position: vec3<f32>,
    // and color at location 1
    @location(1) uv: vec2<f32>,
};

// This is the output of the vertex shader and we also use it as the input for the fragment shader
struct VertexOutput {
    @builtin(position) clip_position: vec4<f32>,
    @location(0) uv: vec2<f32>,
};

@vertex
fn vertex(vertex: Vertex) -> VertexOutput {
    var out: VertexOutput;
    // This is how bevy computes the world position
    // The vertex.instance_index is very important. Especially if you are using batching and gpu preprocessing
    var world_from_local = mesh_functions::get_world_from_local(vertex.instance_index);
    var world_position = mesh_functions::mesh_position_local_to_world(world_from_local, vec4(vertex.position, 1.0));
    out.clip_position = position_world_to_clip(world_position.xyz);
    out.uv = vertex.uv;
    return out;
}

@fragment
fn fragment(mesh: VertexOutput) -> @location(0) vec4<f32> {
    // output the color directly
    return vec4(1.0,0.0,0.0, 1.0);
}

pub(crate) const SHADER_STROKE_PATH: &str = "shaders/player/shader_stroke.wgsl";

// This is the struct that will be passed to your shader

pub(crate) struct StrokeMaterial {
    // #[uniform(0)]

impl Material2d for StrokeMaterial {

    fn vertex_shader() -> ShaderRef {
        SHADER_STROKE_PATH.into()
    }
    fn fragment_shader() -> ShaderRef {
        SHADER_STROKE_PATH.into()
    }

    // fn alpha_mode(&self) -> AlphaMode2d {
    //     AlphaMode2d::Mask(0.5)
    // }

    fn specialize(
        descriptor: &mut RenderPipelineDescriptor,
        layout: &MeshVertexBufferLayoutRef,
        key: Material2dKey<Self>,
    ) -> Result<(), SpecializedMeshPipelineError> {
        let vertex_layout = layout.0.get_layout(&[
            Mesh::ATTRIBUTE_POSITION.at_shader_location(0),
            Mesh::ATTRIBUTE_UV_0.at_shader_location(1),
        ])?;
        descriptor.vertex.buffers = vec![vertex_layout];
        Ok(())
    }
}

...
commands.spawn((
            Mesh2d(meshes.add(Rectangle::new(1056., 252.))),
            MeshMaterial2d(materials.add(player_shader_api::StrokeMaterial {
                // color: LinearRgba::BLUE,
                color_texture: Some(images.add(player_asset.get_image())),
            })),
            Transform::default().with_scale(Vec3::from_array([1.,1.,1.])),
        ));

When I run it, the error is as follows:

How to bind the position and uv of Rust to WGSL? Thank you very much！

[Henauxg]

You are declaring a texture and a sampler in your rust code with

   #[texture(1)]
   #[sampler(2)]
   pub(crate) color_texture: Option<Handle<Image>>,

You probably also want to declare these bindings in your WGSL shader code like this:

// ...

struct VertexOutput {
    @builtin(position) clip_position: vec4<f32>,
    @location(0) uv: vec2<f32>,
};

@group(2) @binding(1) var texture: texture_2d<f32>;
@group(2) @binding(2) var texture_sampler: sampler;

// ...

This is my key code now. When I change Material2D to Material, it can display some red images normally. Now it reports an error:

Your imports in your shader are referencing bevy_pbr instead of bevy_sprite

Use something like:

#import bevy_sprite::{mesh2d_functions::{get_world_from_local, mesh2d_position_local_to_clip}}

and mesh2d_position_local_to_clip instead of mesh_position_local_to_clip

You are the smartest person in the world, the problem has been solved, thank you very much!!!
