unity3d 教程下载须知

在进行Unity3D教程下载时，确实有一些问题需要我们特别关注。接下来，我们将详细探讨下载过程中需要注意的相关内容，以及较为正确的下载方式。

在下载Unity3D教程时，必须对教程的核心内容多加留意。这是因为核心内容是整个教程的关键所在，如果这些内容有所欠缺，那么在学习过程中就会遇到诸多困扰。所以，在下载教程时，务必仔细查看核心内容，确保其完整性。采用这种方式下载教程是比较正确的，大家可以借鉴学习。

以下是一些代码片段，虽然它们未直接关联到Unity3D教程下载，但可能在相关开发过程中会有所帮助：

Java代码示例

public String getUserTest() {
try {
List<UserModel> orgs = userService.getUserTest(model);
int count = userService.getUser().size();
String result = GsonUtil.toJson(orgs, new TypeToken<List<UserModel>>() {}.getType());
json(true, result, count);
} catch (ServiceException e) {
json(false, e.getMessage());
}
return null;
}

JavaScript代码示例

搜索用户信息

onres: function(widget, event) {
var store = this.getStore();
var me = this;
var username = Ext.getCmp('user-res').getValue();
Ext.Ajax.request({
url: U.root + 'queryUser.action',
method: "POST",
params: {
username: username
},
scope: this,
success: function(response) {
var text = response.responseText;
var result = Ext.decode(text);
var data = result.data;
if (data === "[]") {
alert("对不起，没有查询到您要的数据");
me.refreshCmp();
} else {
store.getProxy().url = U.root + 'queryUser.action';
store.getProxy().extraParams = {
username: username
};
store.load();
}
},
failure: function() {
Ext.Msg.alert('提示', '搜索失败');
}
});
}

绘制雪花动画

var array = new Array();
var canvas = document.getElementById("mycanvas");
var context = canvas.getContext("2d");
for (var i = 0; i < 50; i++) {
var Showsnow = new showsnow();
array.push(Showsnow);
}
time = setInterval(function () {
context.clearRect(0, 0, canvas.width, canvas.height);
for (var i = 0; i < array.length; i++) {
array[i].move();
array[i].draw(context);
}
}, 500);

function showsnow() {
var y = parseInt(Math.random() * 50) * 10;
var x = parseInt(Math.random() * 80) * 10;
this.draw = function(context) {
context.font = "50px Calibri";
context.fillText("*", x, y);
};
this.move = function() {
y += 20;
if (y > 600) {
y = 0;
}
};
}

C#代码示例

Stream input = Request.InputStream;
input.Seek(0, SeekOrigin.Begin);
byte[] buffer = new byte[input.Length];
Request.InputStream.Read(buffer, 0, (int)input.Length);
string inputString = Encoding.UTF8.GetString(buffer);
dynamic json = Newtonsoft.Json.JsonConvert.DeserializeObject<dynamic>(inputString);
ExtResult result = new ExtResult();
result.tid = json.tid;
result.action = json.action;
result.method = json.method;
result.type = json.type;
string method = json.method;
switch (method) {
case "GetUserList": {
result.result = GetUserList();
break;
}
case "GetUser": {
string name = json.data.name;
result.result = GetUser(name);
break;
}
}
return Json(result);

public List<User> GetUserList() {
return UserList;
}

public User GetUser(string name) {
return UserList.Find(m => m.name == name);
}

public class ExtResult {
public string action { get; set; }
public string method { get; set; }
public int tid { get; set; }
public string type { get; set; }
public object result { get; set; }
}

获取用户列表并提示信息

GetUserList(function (result, event, success, options) {
var msg = [];
Ext.Array.each(result, function (item) {
msg.push(item.name + "  " + item.age);
});
Ext.MessageBox.alert('提示', msg.join('<br />'));
store = Ext.create('Ext.data.Store', {
model: 'Person',
proxy: {
type: 'direct',
directFn: User.GetUserList
}
});
});

var polling = Ext.create('Ext.direct.PollingProvider', {
url: rootUrl + 'DirectAPI/GetMessage',
type: 'polling',
interval: 5000,
listeners: {
data: function (provider, e, eOpts) {
Ext.MessageBox.alert('', e.data.msg);
}
},
id: 'GetMessagePolling'
});

定义Person类

function Person() {
this.head = 1;
this.legs = 2;
this.sex = "or";
}

Person.prototype = {
say: function () {
alert("I'm a person , I have " + this.head + " head and " + this.legs + " legs.");
},
run: function () {
alert("I can fly ,because I have " + this.head + " head");
},
saySex: function() {
alert("I'm a " + this.sex);
}
};

var person = new Person();
alert(person.head);
