unity血条

通过修改贴图的宽度来实现进度条的功能，以血条为例，若100%生命值时HealthBar的贴图宽度为Width， 当生命值为x%时，只要修改HealthBar的宽度为Width*x%即可。

HealthBar.pixelInset = new Rect()

{

x = HealthBar.pixelInset.x,

y = HealthBar.pixelInset.y,

width = m_StandardHealth

　　修改一下，基本上代码差不多可以直接用了。看一看你很容易就懂了。

//默认npc坐标点在脚底下，所以这里加上npcheight它模型的高度即可

//根据npc头顶的3d坐标换算成它在2d屏幕中的坐标
vector2 position = camera.worldtoscreenpoint (worldposition);
//得到真实npc头顶的2d坐标
position = new vector2 (position.x, screen.height - position.y);
//注解2
//计算出血条的宽高
