//得到所有可渲染的子物体
Renderer[] rds = transform.GetComponentsInChildren<Renderer>();
//逐一遍历他的子物体中的Renderer
foreach (Renderer render in rds)
{
//逐一遍历子物体的子材质(renderer中的material)
foreach (Material material in render.materials)
{
var r = material.color.r;
var g = material.color.g;
var b = material.color.b;
material.color = new Color(r, g, b, _Alpha);
}
}
附加的判断
var render = transform.GetComponent<Renderer>();
if (render != null)
{
foreach (Material material in render.materials)
{
var r = material.color.r;
var g = material.color.g;
var b = material.color.b;
material.color = new Color(r, g, b, _Alpha);
}
}
