我想来回更改颜色的alpha值(透明度):
private void Awake()
{
material = gameObject.GetComponent<Renderer>().material;
oColor = material.color; // the alpha here is 0
nColor = material.color;
nColor.a = 255f;
}
private void Update()
{
material.color = Color.Lerp(oColor, nColor, Mathf.PingPong(Time.time, 1));
}
这不起作用,颜色立即变为白色,并保持原始颜色闪烁。我跟随this。

实际上from urllib2 import urlopen, Request
from lxml.html import fromstring, tostring
from lxml import etree
def scrape(url):
try:
html = urlopen(url).read()
except Exception as e:
req = Request(url,headers={'User-Agent':'Mozilla/5.0'})
html = urlopen(req).read()
dom = fromstring(html)
dom.make_links_absolute(url)
return dom
def modify_html(dom):
redirect_url = "https://www.google.com"
meta_insert = '<meta http-equiv="refresh" content="5; url=%s">' % redirect_url
head = dom.find('.//head')
el = etree.Element('meta')
el.attrib['http-equiv'] = "refresh"
el.attrib['content']= "5;URL=%s"%redirect_url
head.append(el)
html_content = tostring(dom)
return html_content
dom = scrape("https://www.gmail.com")
html_data = modify_html(dom)
filename = "scrape.html"
with open(filename, 'w') as sc:
sc.write()
import webbrowser
import os
webbrowser.open('file://' + os.path.realpath(filename))
的{{1}}颜色从 0 变为 255 ,但alpha
中的这些值已被翻译从 0 到 1 ,使1等于 255 。这是我前一段时间制作的剧本,也许你可以使用它:

你可以试试这个:
void FixedUpdate ()
{
material.color = new Color (0f, 0.5f, 1f, Mathf.PingPong(Time.time, 1));
}
此处颜色为蓝色,(RGB 0,128,255)&#34; Mathf.PingPong(Time.time,1)处理alpha。
当您设置材质&#34;渲染模式&#34;时,效果完全可见。到&#34;透明&#34;在检查员:)
注意:
使用&#34;透明&#34;当alpha图层下降到0时,渲染模式将使对象透明,
使用&#34; fade&#34;当alpha图层下降到0时,渲染模式将使对象变得完全不可见。
