Mathf.Clamp(a,b,c);

返回zhi类型的范围在b-c之间

Debug.log(a+b);//显示出ab的值

public int maxHealth = 5;//最大生命值
    private int currentHealth;//Ruby的当前生命值（可变）

currentHealth = maxHealth; 
 

 private void ChangeHealth(int amount)//改变生命值，增加或减少
    {
        currentHealth = Mathf.Clamp(currentHealth + amount, 0, maxHealth);
        Debug.Log(currentHealth + "/" + maxHealth);
    }

class:
{
pubic int maxHealth=5;
private int currenthealth;
}
void start()
{
 current health=maxHealth
}
private void ChangeHealth(int amount)
{
 currentHealth=Mathf.Clamp(current health+amount,0,maxHealth)
}

Clamp方法？

结果输出在控制台：Debug.Log(currentHealth+"/"+maxHealth)

Mathf.Clamp(currentHealth+amout,0,maxHeath);

限定第一个参数，最小值，最大值。
