# setVertexSamplerState(_:index:)

Assigns a sampler state to an entry in the vertex shader argument table.

## Declaration

```swift
func setVertexSamplerState(_ sampler: (any MTLSamplerState)?, index: Int)
```

## Parameters

- `sampler`: An doc://com.apple.metal/documentation/Metal/MTLSamplerState instance the command assigns to an entry in the vertex shader argument table for sampler states.
- `index`: An integer that represents the entry in the vertex shader argument table for sampler states that stores a record of sampler.

## Discussion

Discussion By default, the sampler state at each index is nil.
