This is the run-time script which animates the attached GameObject:

```csharp
// Note that this must be FollowAnimationCurve.cs

using UnityEngine;
using System.Collections;

public class FollowAnimationCurve : MonoBehaviour
{
    public AnimationCurve curveX;
    public AnimationCurve curveY;
    public AnimationCurve curveZ;

    public void SetCurves(AnimationCurve xC, AnimationCurve yC, AnimationCurve zC)
    {
        curveX = xC;
        curveY = yC;
        curveZ = zC;
    }

    void Update()
    {
        transform.position = new Vector3(
            curveX.Evaluate(Time.time),
            curveY.Evaluate(Time.time),
            curveZ.Evaluate(Time.time));
    }
}
```

## CurveField(Rect, SerializedProperty, Color, Rect)

Makes a field for editing an [AnimationCurve](/engine/6000.3/script-reference/unityengine/animationcurve.md).

```csharp
public static void CurveField(Rect position, SerializedProperty property, Color color, Rect ranges)
```

### Parameters

**** (\[Rect]\(/engine/6000.3/script-reference/unityengine/rect)): Rectangle on the screen to use for the field.**** (\[SerializedProperty]\(/engine/6000.3/script-reference/unityeditor/serializedproperty)): The curve to edit.**** (\[Color]\(/engine/6000.3/script-reference/unityengine/color)): The color to show the curve with.**** (\[Rect]\(/engine/6000.3/script-reference/unityengine/rect)): Optional rectangle that the curve is restrained within.

## CurveField(Rect, SerializedProperty, Color, Rect, GUIContent)

Makes a field for editing an [AnimationCurve](/engine/6000.3/script-reference/unityengine/animationcurve.md).

```csharp
public static void CurveField(Rect position, SerializedProperty property, Color color, Rect ranges, GUIContent label)
```

### Parameters

**** (\[Rect]\(/engine/6000.3/script-reference/unityengine/rect)): Rectangle on the screen to use for the field.**** (\[SerializedProperty]\(/engine/6000.3/script-reference/unityeditor/serializedproperty)): The curve to edit.**** (\[Color]\(/engine/6000.3/script-reference/unityengine/color)): The color to show the curve with.**** (\[Rect]\(/engine/6000.3/script-reference/unityengine/rect)): Optional rectangle that the curve is restrained within.**** (\[GUIContent]\(/engine/6000.3/script-reference/unityengine/guicontent)): Optional label to display in front of the field. Pass \[\[GUIContent.none] to hide the label.
