{{函数详情
|函数名 = Function: llSetAlpha( float alpha, integer face );
|参数= 参数：
• float alpha – 
from 0.0 (clear) to 1.0 (solid) (0.0 <= alpha <= 1.0) 

• integer 
face 
– 
face number or ALL_SIDES
|返回值= 返回值：将alpha设置在face上

如果面是ALL_SIDES，那么函数对所有面都起作用。

|注意事项=如果该函数的面值表示一个不存在的面值，则该函数将悄无声息地失败。

|示例=
<pre>
float cloakSpeed = 0.1;
 
default
{
    touch_end(integer total_number)
    {
        float alpha = 1.0;
        while(alpha > 0.0)
        {
            alpha -= 0.1;
            llSetAlpha(alpha, ALL_SIDES);
            llSleep(cloakSpeed);
        }
        state cloaked;
    }
}
 
state cloaked
{
    touch_end(integer total_number)
    {
        float alpha;
        while (alpha < 1.0)
        {
            alpha += 0.1;
            llSetAlpha(alpha, ALL_SIDES);
            llSleep(cloakSpeed);
        }
        state default;
    }
}
</pre>
