new

shaderArgsBuilderNew

Arguments

:: (HasCallStack, MonadIO m, IsGLShader a)

=> a

shader: a GskGLShader

-> Maybe Bytes

initialValues: optional GBytes with initial values

-> m ShaderArgsBuilder

Returns: The newly allocated builder, free with shaderArgsBuilderUnref

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

ref

shaderArgsBuilderRef

Arguments

:: (HasCallStack, MonadIO m)

=> ShaderArgsBuilder

builder: a GskShaderArgsBuilder

-> m ShaderArgsBuilder

Returns: the passed in GskShaderArgsBuilder

Increases the reference count of a GskShaderArgsBuilder by one.

setBool

shaderArgsBuilderSetBool

Arguments

:: (HasCallStack, MonadIO m)

=> ShaderArgsBuilder

builder: a GskShaderArgsBuilder

-> Int32

idx: index of the uniform

-> Bool

value: value to set the uniform to

-> m ()

Sets the value of the uniform idx.

The uniform must be of bool type.

setFloat

shaderArgsBuilderSetFloat

Arguments

:: (HasCallStack, MonadIO m)

=> ShaderArgsBuilder

builder: a GskShaderArgsBuilder

-> Int32

idx: index of the uniform

-> Float

value: value to set the uniform to

-> m ()

Sets the value of the uniform idx.

The uniform must be of float type.

setInt

shaderArgsBuilderSetInt

Arguments

:: (HasCallStack, MonadIO m)

=> ShaderArgsBuilder

builder: a GskShaderArgsBuilder

-> Int32

idx: index of the uniform

-> Int32

value: value to set the uniform to

-> m ()

Sets the value of the uniform idx.

The uniform must be of int type.

setUint

shaderArgsBuilderSetUint

Arguments

:: (HasCallStack, MonadIO m)

=> ShaderArgsBuilder

builder: a GskShaderArgsBuilder

-> Int32

idx: index of the uniform

-> Word32

value: value to set the uniform to

-> m ()

Sets the value of the uniform idx.

The uniform must be of uint type.

setVec2

shaderArgsBuilderSetVec2

Arguments

:: (HasCallStack, MonadIO m)

=> ShaderArgsBuilder

builder: A GskShaderArgsBuilder

-> Int32

idx: index of the uniform

-> Vec2

value: value to set the uniform too

-> m ()

Sets the value of the uniform idx.

The uniform must be of vec2 type.

setVec3

shaderArgsBuilderSetVec3

Arguments

:: (HasCallStack, MonadIO m)

=> ShaderArgsBuilder

builder: a GskShaderArgsBuilder

-> Int32

idx: index of the uniform

-> Vec3

value: value to set the uniform too

-> m ()

Sets the value of the uniform idx.

The uniform must be of vec3 type.

setVec4

shaderArgsBuilderSetVec4

Arguments

:: (HasCallStack, MonadIO m)

=> ShaderArgsBuilder

builder: a GskShaderArgsBuilder

-> Int32

idx: index of the uniform

-> Vec4

value: value to set the uniform too

-> m ()

Sets the value of the uniform idx.

The uniform must be of vec4 type.

toArgs

shaderArgsBuilderToArgs

Arguments

:: (HasCallStack, MonadIO m)

=> ShaderArgsBuilder

builder: a GskShaderArgsBuilder

-> m Bytes

Returns: the newly allocated buffer with all the args added to builder

Creates a new GBytes 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 GskShaderArgsBuilder 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 ShaderArgsBuilder.free_to_args().

unref

shaderArgsBuilderUnref

Arguments

:: (HasCallStack, MonadIO m)

=> ShaderArgsBuilder

builder: a GskShaderArgsBuilder

-> m ()

Decreases the reference count of a GskShaderArgBuilder by one.

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