Struct VfxVariableIndexData

Namespace: ValveResourceFormat.CompiledShader
Assembly: ValveResourceFormat.dll

One write sequence entry: a variable index paired with the register offset it is written to.

public readonly struct VfxVariableIndexData

Remarks

Resource encoded shaders store each entry as one 32-bit value that is reinterpreted as this struct, so the field order and size are part of the format: register offset in the low half, packed index in the high half.

Properties

BindingSlot

Gets the binding slot, the low byte of the register offset. It is 255 when the variable has no register.

public int BindingSlot { get; }

Property Value

int

Control

Gets the high byte of the register offset. Only meaningful for constant buffer bindings, where it appears to be the buffer's base register in a linearly allocated constant register space.

public int Control { get; }

Property Value

int

LayoutSet

Gets the descriptor set ID in the shader layout.

public int LayoutSet { get; }

Property Value

int

PackedIndex

Gets the packed variable index and layout set.

public short PackedIndex { get; init; }

Property Value

short

RegisterOffset

Gets the register offset the variable is written to.

public short RegisterOffset { get; init; }

Property Value

short

VariableIndex

Gets the variable index into VfxProgramData.VariableDescriptions.

public int VariableIndex { get; }

Property Value

int
