RDPipelineColorBlendStateAttachment

Pipeline color blend state attachment (used by RenderingDevice).

RDPipelineColorBlendStateAttachment.swift:24

class RDPipelineColorBlendStateAttachment

Mangled symbol

s10SwiftGodot35RDPipelineColorBlendStateAttachmentCWhat are these?

FNV24: [8G7L4]

Controls how blending between source and destination fragments is performed when using RenderingDevice.

For reference, this is how common user-facing blend modes are implemented in Godot’s 2D renderer:

Mix:

Add:

Subtract:

Multiply:

Pre-multiplied alpha:

Superclasses

class RefCounted
Base class for reference-counted objects.

Conformances

protocol CustomStringConvertible
A type with a customized textual representation.
protocol Equatable
A type that can be compared for value equality.
protocol Hashable
A type that can be hashed into a Hasher to produce an integer hash value.
protocol Identifiable<ID>
A class of types whose instances hold the value of an entity with stable identity.
protocol VariantRepresentable
Types that conform to VariantRepresentable can be stored directly in Variant with no conversion. These include all of the Variant types from Godot (for example GString, Rect, Plane), Godot objects (those that subclass SwiftGodot.Object) as well as the built-in Swift types UInt8, Int64 and Double.
protocol VariantStorable
Types that conform to VariantStorable can be stored in a Variant and can be extracted back out of a Variant.

Type members

Instance members

var alphaBlendOp: RenderingDevice.BlendOperation
The blend mode to use for the alpha channel.
var colorBlendOp: RenderingDevice.BlendOperation
The blend mode to use for the red/green/blue color channels.
var dstAlphaBlendFactor: RenderingDevice.BlendFactor
Controls how the blend factor for the alpha channel is determined based on the destination’s fragments.
var dstColorBlendFactor: RenderingDevice.BlendFactor
Controls how the blend factor for the color channels is determined based on the destination’s fragments.
var enableBlend: Bool
If true, performs blending between the source and destination according to the factors defined in srcColorBlendFactor, dstColorBlendFactor, srcAlphaBlendFactor and dstAlphaBlendFactor. The blend modes colorBlendOp and alphaBlendOp are also taken into account, with writeR, writeG, writeB and writeA controlling the output.
var srcAlphaBlendFactor: RenderingDevice.BlendFactor
Controls how the blend factor for the alpha channel is determined based on the source’s fragments.
var srcColorBlendFactor: RenderingDevice.BlendFactor
Controls how the blend factor for the color channels is determined based on the source’s fragments.
var writeA: Bool
If true, writes the new alpha channel to the final result.
var writeB: Bool
If true, writes the new blue color channel to the final result.
var writeG: Bool
If true, writes the new green color channel to the final result.
var writeR: Bool
If true, writes the new red color channel to the final result.
func setAsMix()
Convenience method to perform standard mix blending with straight (non-premultiplied) alpha. This sets enableBlend to true, srcColorBlendFactor to srcAlpha, dstColorBlendFactor to oneMinusSrcAlpha, srcAlphaBlendFactor to srcAlpha and dstAlphaBlendFactor to oneMinusSrcAlpha.
