Silverlight的随机动画效果
时间：2010-09-06 来源：永恒的记忆
1.建立随机粒子类
public class Cellule
{
public Cellule()
{
Age = 0;
}
public Brush GetBrush()
{
if (isLibre() == true) return new SolidColorBrush(Colors.Transparent);
Brush brush = null;
if (Age == 1)
brush = new SolidColorBrush(Colors.Yellow);
else if (Age == 2)
brush = new SolidColorBrush(Colors.Orange);
else if (Age == 3)
brush = new SolidColorBrush(Colors.Magenta);
else if (Age < 10)
brush = new SolidColorBrush(Colors.Blue);
else if (Age < 15)
brush = new SolidColorBrush(Colors.Green);
else
brush = new SolidColorBrush(Colors.Red);
return brush;
}
public void Copy(Cellule src)
{
this.Age = src.Age;
}
public bool isLibre()
{
return (Age == 0);
}
public bool isOccupe()
{
return (Age > 0);
}
public void Naissance()
{
Age = 1;
}
public void Meurt()
{
Age = 0;
}
public void Survie()
{
Age++;
}
public int Age;
