Struct Pass 

pub struct Pass { /* private fields */ }

A struct representing a shader pass.

Implementations

impl Pass

pub fn set_grab_pass(&mut self, val: bool)

Sets whether this Pass should be a grab pass. A grab pass will render a portion of game scene into a texture frame buffer. Then use this texture frame buffer as an input for next render pass.

pub fn is_grab_pass(&self) -> bool

Gets whether this Pass should be a grab pass. A grab pass will render a portion of game scene into a texture frame buffer. Then use this texture frame buffer as an input for next render pass.

pub fn set(&mut self, name: &str, val: f32)

Sets the value of shader parameters.

Arguments

• name - The name of the parameter to set.
• val - The numeric value to set.

pub fn set_vec4( &mut self, name: &str, val_1: f32, val_2: f32, val_3: f32, val_4: f32, )

Sets the values of shader parameters.

Arguments

• name - The name of the parameter to set.
• val1 - The first numeric value to set.
• val2 - An optional second numeric value to set.
• val3 - An optional third numeric value to set.
• val4 - An optional fourth numeric value to set.

pub fn set_color(&mut self, name: &str, val: &Color)

Another function that sets the values of shader parameters.

Works the same as: pass.set(“varName”, color.r / 255.0, color.g / 255.0, color.b / 255.0, color.opacity);

Arguments

• name - The name of the parameter to set.
• val - The Color object to set.

pub fn new(vert_shader: &str, frag_shader: &str) -> Pass

Creates a new Pass object.

Arguments

• vert_shader - The vertex shader in binary form file string.
• frag_shader - The fragment shader file string. A shader file string must be one of the formats:
  • “builtin:” + theBuiltinShaderName
  • “Shader/compiled_shader_file.bin”

Returns

• Pass - A new Pass object.
