# Mathf.Clamp

Cambiar al Manual
public static float Clamp (float value, float min, float max);

## Parámetros

 value The floating point value to restrict inside the range defined by the min and max values. min The minimum floating point value to compare against. max The maximum floating point value to compare against.

## Valor de retorno

float The float result between the min and max values.

## Descripción

Clamps the given value between the given minimum float and maximum float values. Returns the given value if it is within the min and max range.

Returns the min value if the given float value is less than the min. Returns the max value if the given value is greater than the max value. Use Clamp to restrict a value to a range that is defined by the min and max values.

```using UnityEngine;// Mathf.Clamp example.
//
// Animate a cube along the x-axis using a sine wave.
// Let the minimum and maximum positions on the x-axis
// be changed.  The cube will be visible inside the
// minimum and maximum values.public class ExampleScript : MonoBehaviour
{
private float xMin = -1.0f, xMax = 1.0f;
private float timeValue = 0.0f;    void Update()
{
// Compute the sin position.
float xValue = Mathf.Sin(timeValue * 5.0f);        // Now compute the Clamp value.
float xPos = Mathf.Clamp(xValue, xMin, xMax);        // Update the position of the cube.
transform.position = new Vector3(xPos, 0.0f, 0.0f);        // Increase animation time.
timeValue = timeValue + Time.deltaTime;        // Reset the animation time if it is greater than the planned time.
if (xValue > Mathf.PI * 2.0f)
{
timeValue = 0.0f;
}
}    void OnGUI()
{
// Let the minimum and maximum values be changed
xMin = GUI.HorizontalSlider(new Rect(25, 25, 100, 30), xMin, -1.0f, +1.0f);
xMax = GUI.HorizontalSlider(new Rect(25, 60, 100, 30), xMax, -1.0f, +1.0f);        // xMin is kept less-than or equal to xMax.
if (xMin > xMax)
{
xMin = xMax;
}        // Display the xMin and xMax value with better size labels.
GUIStyle fontSize = new GUIStyle(GUI.skin.GetStyle("label"));
fontSize.fontSize = 24;        GUI.Label(new Rect(135, 10, 150, 30), "xMin: " + xMin.ToString("f2"), fontSize);
GUI.Label(new Rect(135, 45, 150, 30), "xMax: " + xMax.ToString("f2"), fontSize);
}
}
```

public static int Clamp (int value, int min, int max);

## Parámetros

 value The integer point value to restrict inside the min-to-max range min The minimum integer point value to compare against. max The maximum integer point value to compare against.

## Valor de retorno

int The int result between min and max values.

## Descripción

Clamps the given value between a range defined by the given minimum integer and maximum integer values. Returns the given value if it is within min and max.

Returns the min value if the given value is less than the min value. Returns the max value if the given value is greater than the max value. The min and max parameters are inclusive. For example, Clamp(10, 0, 5) will return a maximum argument of 5 and not 4.

```using UnityEngine;// Mathf.Clamp integer example.
//
// Add or subtract values from health.
// Keep health between 1 and 100. Start at 17.public class ExampleScript : MonoBehaviour
{

private int xButton = 75;
private int yButton = 50;    // Place of the top left button.
private int xPos1 = 50, yPos1 = 100;
private int xPos2 = 125, yPos2 = 100;    void OnGUI()

}
}        // Generate and show negative buttons.
for (int i = 0; i < healthDown.Length; i++)
{
if (GUI.Button(new Rect(xPos2, yPos2 + i * yButton, xButton, yButton), healthDown[i].ToString()))
{
health += healthDown[i];
}
}        // Show health between 1 and 100.
health = Mathf.Clamp(health, 1, 100);
GUI.Label(new Rect(xPos1, xPos1, 2 * xButton, yButton), "Health: " + health.ToString("D3"));
}
}
