在动画中创建一个按钮或者点击事件触发mailto。

使用以下代码创建一个mailto链接，包含主题、收件人、邮件内容和附件路径。

var subject:String = "邮件主题";
var recipient:String = "收件人邮箱";
var body:String = "邮件内容";
var attachment:File = File.applicationStorageDirectory.resolvePath("附件路径");
var request:String = "mailto:" + recipient + "?subject=" + subject + "&body=" + body;
navigateToURL(new URLRequest(request));

此时只能发送文本内容，如果需要发送附件，则需要使用SMTP服务器和相应的代码库实现。可以使用AS3Mailer库或者其他外部邮件库来实现。

使用AS3Mailer库的示例代码：

var server:String = "SMTP服务器";
var port:int = 25;
var username:String = "发件人邮箱";
var password:String = "发件人邮箱密码";
var sender:String = "发件人邮箱";
var recipient:String = "收件人邮箱";
var subject:String = "邮件主题";
var body:String = "邮件内容";
var attachment:ByteArray = 读取附件为ByteArray;

var mailer:AS3Mailer = new AS3Mailer(server, port, sender, username, password);
mailer.addRecipient(recipient);
mailer.setSubject(subject);
mailer.setMessage(body);
mailer.addAttachment(attachment, "附件名称");
mailer.send();
