# SetAllVertices

> Fills the values of the allocated vertices with values copied directly from an array. When this method is called, it is not possible to use MeshWriteData.SetNextVertex to fill the allocated vertices array.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine.UIElements](/engine/6000.0/script-reference/unityengine/uielements.md)
* **Assembly:** UnityEngine.UIElementsModule

## SetAllVertices(Vertex\[])

Fills the values of the allocated vertices with values copied directly from an array. When this method is called, it is not possible to use [MeshWriteData.SetNextVertex](/engine/6000.0/script-reference/unityengine/uielements/meshwritedata/setnextvertex.md) to fill the allocated vertices array.

```csharp
public void SetAllVertices(Vertex[] vertices)
```

### Parameters

**** (\[Vertex\[]]\(/engine/6000.0/script-reference/unityengine/uielements/vertex)): The array of vertices to copy from. The length of the array must match the allocated vertex count.

### Remarks

When this method is called, it is not possible to use [MeshWriteData.SetNextVertex](/engine/6000.0/script-reference/unityengine/uielements/meshwritedata/setnextvertex.md) to fill the vertices.

### Examples

```csharp
public class MyVisualElement : VisualElement
{
    void MyGenerateVisualContent(MeshGenerationContext mgc)
    {
        var meshWriteData = mgc.Allocate(4, 6);
        // meshWriteData has been allocated with 6 indices for 2 triangles

        // ... set the vertices

        // Set indices for the first triangle
        meshWriteData.SetNextIndex(0);
        meshWriteData.SetNextIndex(1);
        meshWriteData.SetNextIndex(2);

        // Set indices for the second triangle
        meshWriteData.SetNextIndex(2);
        meshWriteData.SetNextIndex(1);
        meshWriteData.SetNextIndex(3);
    }
}
```

## SetAllVertices(NativeSlice\<Vertex>)

Fills the values of the allocated vertices with values copied directly from an array. When this method is called, it is not possible to use [MeshWriteData.SetNextVertex](/engine/6000.0/script-reference/unityengine/uielements/meshwritedata/setnextvertex.md) to fill the allocated vertices array.

```csharp
public void SetAllVertices(NativeSlice<Vertex> vertices)
```

### Parameters

**** (\[NativeSlice\<Vertex>]\(/engine/6000.0/script-reference/unity/collections/nativeslice1)): The array of vertices to copy from. The length of the array must match the allocated vertex count.

### Remarks

When this method is called, it is not possible to use [MeshWriteData.SetNextVertex](/engine/6000.0/script-reference/unityengine/uielements/meshwritedata/setnextvertex.md) to fill the vertices.
