Description

An object to build the uniforms data for a Gnome::Gsk4::GLShader.

Class initialization

new

:native-object

Create an object using a native object from elsewhere. See also Gnome::N::TopLevelSupportClass.

multi method new ( N-Object :$native-object! )

new-shaderargsbuilder

Allocates a builder that can be used to construct a new uniform data chunk.

method new-shaderargsbuilder ( N-Object() $shader, N-Object $initial-values --> Gnome::Gsk4::ShaderArgsBuilder \)

• $shader; a Gnome::Gsk4::GLShader.

• $initial-values; optional Gnome::Glib::N-Bytes with initial values

Methods

free-to-args

Creates a new Gnome::Glib::N-Bytes args from the current state of the given $builder, and frees the $builder instance.

Any uniforms of the shader that have not been explicitly set on the $builder are zero-initialized.

method free-to-args (--> N-Object )

Return value; the newly allocated buffer with all the args added to $builder.

ref

Increases the reference count of a Gnome::Gsk4::N-ShaderArgsBuilder by one.

method ref (--> N-Object )

Return value; the passed in Gnome::Gsk4::N-ShaderArgsBuilder.

set-bool

Sets the value of the uniform $idx.

The uniform must be of bool type.

method set-bool ( Int() $idx, Bool() $value )

• $idx; index of the uniform.

• $value; value to set the uniform to.

set-float

Sets the value of the uniform $idx.

The uniform must be of float type.

method set-float ( Int() $idx, Num() $value )

• $idx; index of the uniform.

• $value; value to set the uniform to.

set-int

Sets the value of the uniform $idx.

The uniform must be of int type.

method set-int ( Int() $idx, Int() $value )

• $idx; index of the uniform.

• $value; value to set the uniform to.

set-uint

Sets the value of the uniform $idx.

The uniform must be of uint type.

method set-uint ( Int() $idx, UInt() $value )

• $idx; index of the uniform.

• $value; value to set the uniform to.

set-vec2

Sets the value of the uniform $idx.

The uniform must be of vec2 type.

method set-vec2 ( Int() $idx, N-Object $value )

• $idx; index of the uniform.

• $value; value to set the uniform too

set-vec3

Sets the value of the uniform $idx.

The uniform must be of vec3 type.

method set-vec3 ( Int() $idx, N-Object $value )

• $idx; index of the uniform.

• $value; value to set the uniform too

set-vec4

Sets the value of the uniform $idx.

The uniform must be of vec4 type.

method set-vec4 ( Int() $idx, N-Object $value )

• $idx; index of the uniform.

• $value; value to set the uniform too

to-args

Creates a new Gnome::Glib::N-Bytes args from the current state of the given $builder.

Any uniforms of the shader that have not been explicitly set on the $builder are zero-initialized.

The given Gnome::Gsk4::N-ShaderArgsBuilder is reset once this function returns; you cannot call this function multiple times on the same $builder instance.

This function is intended primarily for bindings. C code should use .free-to-args().

method to-args (--> N-Object )

Return value; the newly allocated buffer with all the args added to $builder.

unref

Decreases the reference count of a GskShaderArgBuilder by one.

If the resulting reference count is zero, frees the builder.

method unref ( )
