# MultiTexCoord2(int, float, float)

> Sets current texture coordinate (x,y) for the actual texture unit.

## Definition

* **Type:** Method
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.CoreModule

```csharp
public static void MultiTexCoord2(int unit, float x, float y)
```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): **** (\[float]\(https\://learn.microsoft.com/dotnet/api/system.single)): **** (\[float]\(https\://learn.microsoft.com/dotnet/api/system.single)): 

### Remarks

In OpenGL this matches `glMultiTexCoord` for the given texture unit if multi-texturing is available. On other graphics APIs the same functionality is emulated.

This function can only be called between [GL.Begin](/engine/6000.7/script-reference/unityengine/gl/begin.md) and [GL.End](/engine/6000.7/script-reference/unityengine/gl/end.md) functions.

### Examples

```csharp
using UnityEngine;

public class Example : MonoBehaviour
{
    // Changes between two textures assigned to a material
    // When pressed space
    Material mat;
    bool flagTex = true;

    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space))
        {
            if (flagTex)
            {
                flagTex = false;
            }
            else
            {
                flagTex = true;
            }
        }
    }

    void OnPostRender()
    {
        if (!mat)
        {
            Debug.LogError("Please Assign a material on the inspector");
            return;
        }
        GL.PushMatrix();
        mat.SetPass(1);
        GL.LoadOrtho();
        GL.Begin(GL.QUADS);
        if (flagTex)
        {
            GL.MultiTexCoord2(0, 0, 0); // main texture
        }
        else
        {
            GL.MultiTexCoord2(1, 0, 0); // second texture
        }
        GL.Vertex3(0.25f, 0.25f, 0);
        if (flagTex)
        {
            GL.MultiTexCoord2(0, 0, 1);
        }
        else
        {
            GL.MultiTexCoord2(1, 0, 1);
        }
        GL.Vertex3(0.25f, 0.75f, 0);
        if (flagTex)
        {
            GL.MultiTexCoord2(0, 1, 1);
        }
        else
        {
            GL.MultiTexCoord2(1, 1, 1);
        }
        GL.Vertex3(0.75f, 0.75f, 0);
        if (flagTex)
        {
            GL.MultiTexCoord2(0, 1, 0);
        }
        else
        {
            GL.MultiTexCoord2(1, 1, 0);
        }
        GL.Vertex3(0.75f, 0.25f, 0);
        GL.End();
        GL.PopMatrix();
    }
}
