RDPipelineColorBlendStateAttachment
===================================
**Наследует:** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`
Присоединение состояния смешивания цветов конвейера (используется :ref:`RenderingDevice<class_RenderingDevice>`).
.. rst-class:: classref-introduction-group
Описание
----------------
Управляет тем, как выполняется смешивание между исходными и целевыми фрагментами при использовании :ref:`RenderingDevice<class_RenderingDevice>`.
Для справки, вот как реализованы общие пользовательские режимы смешивания в 2D-рендерере Godot:
\ **Mix:**\
::
var attachment = RDPipelineColorBlendStateAttachment.new()
attachment.enable_blend = true
attachment.color_blend_op = RenderingDevice.BLEND_OP_ADD
attachment.src_color_blend_factor = RenderingDevice.BLEND_FACTOR_SRC_ALPHA
attachment.dst_color_blend_factor = RenderingDevice.BLEND_FACTOR_ONE_MINUS_SRC_ALPHA
attachment.alpha_blend_op = RenderingDevice.BLEND_OP_ADD
attachment.src_alpha_blend_factor = RenderingDevice.BLEND_FACTOR_ONE
attachment.dst_alpha_blend_factor = RenderingDevice.BLEND_FACTOR_ONE_MINUS_SRC_ALPHA
\ **Add:**\
::
var attachment = RDPipelineColorBlendStateAttachment.new()
attachment.enable_blend = true
attachment.alpha_blend_op = RenderingDevice.BLEND_OP_ADD
attachment.color_blend_op = RenderingDevice.BLEND_OP_ADD
attachment.src_color_blend_factor = RenderingDevice.BLEND_FACTOR_SRC_ALPHA
attachment.dst_color_blend_factor = RenderingDevice.BLEND_FACTOR_ONE
attachment.src_alpha_blend_factor = RenderingDevice.BLEND_FACTOR_SRC_ALPHA
attachment.dst_alpha_blend_factor = RenderingDevice.BLEND_FACTOR_ONE
\ **Subtract:**\
::
var attachment = RDPipelineColorBlendStateAttachment.new()
attachment.enable_blend = true
attachment.alpha_blend_op = RenderingDevice.BLEND_OP_REVERSE_SUBTRACT
attachment.color_blend_op = RenderingDevice.BLEND_OP_REVERSE_SUBTRACT
attachment.src_color_blend_factor = RenderingDevice.BLEND_FACTOR_SRC_ALPHA
attachment.dst_color_blend_factor = RenderingDevice.BLEND_FACTOR_ONE
attachment.src_alpha_blend_factor = RenderingDevice.BLEND_FACTOR_SRC_ALPHA
attachment.dst_alpha_blend_factor = RenderingDevice.BLEND_FACTOR_ONE
\ **Multiply:**\
::
var attachment = RDPipelineColorBlendStateAttachment.new()
attachment.enable_blend = true
attachment.alpha_blend_op = RenderingDevice.BLEND_OP_ADD
attachment.color_blend_op = RenderingDevice.BLEND_OP_ADD
attachment.src_color_blend_factor = RenderingDevice.BLEND_FACTOR_DST_COLOR
attachment.dst_color_blend_factor = RenderingDevice.BLEND_FACTOR_ZERO
attachment.src_alpha_blend_factor = RenderingDevice.BLEND_FACTOR_DST_ALPHA
attachment.dst_alpha_blend_factor = RenderingDevice.BLEND_FACTOR_ZERO
\ **Pre-multiplied alpha:**\
::
var attachment = RDPipelineColorBlendStateAttachment.new()
attachment.enable_blend = true
attachment.alpha_blend_op = RenderingDevice.BLEND_OP_ADD
attachment.color_blend_op = RenderingDevice.BLEND_OP_ADD
attachment.src_color_blend_factor = RenderingDevice.BLEND_FACTOR_ONE
attachment.dst_color_blend_factor = RenderingDevice.BLEND_FACTOR_ONE_MINUS_SRC_ALPHA
attachment.src_alpha_blend_factor = RenderingDevice.BLEND_FACTOR_ONE
attachment.dst_alpha_blend_factor = RenderingDevice.BLEND_FACTOR_ONE_MINUS_SRC_ALPHA
