本文介绍Unity中使用协程实现定时功能的方法，并演示了一个简易的消息分发机制，包括注册、发送与注销消息。
第十一个示例
代码如下
using
System
;
using
System
.
Collections
;
using
UnityEngine
;
namespace
QFramework
{
public
partial
class
MonoBehaviourSimplify
{
public
void
Delay
(
float
seconds
,
Action
onFinished
)
{
StartCoroutine
(
DelayCoroutine
(
seconds
,
onFinished
)
)
;
}
private
static
IEnumerator
DelayCoroutine
(
float
seconds
,
Action
onFinished
)
{
yield
return
new
WaitForSeconds
(
seconds
)
;
onFinished
(
)
;
}
}
public
class
DelayWithCoroutine
:
MonoBehaviourSimplify
{
private
void
Start
(
)
{
Delay
(
5.0f
,
(
)
=>
{
UnityEditor
.
EditorApplication
.
isPlaying
=
false
;
}
)
;
}
#
if
UNITY_EDITOR
[
UnityEditor
.
MenuItem
(
"QFramework/11.定时功能"
,
false
,
11
)
]
private
static
void
MenuClickd
(
)
{
UnityEditor
.
EditorApplication
.
isPlaying
=
true
;
new
GameObject
(
"DelayWithCoroutine"
)
.
AddComponent
<
DelayWithCoroutine
>
(
)
;
}
#
endif
protected
override
void
OnBeforeDestroy
(
)
{
}
}
}
又一个 MonoBehaviourSimplify，我们可以考虑和之前的示例进行合并。而我们的 DelayWithCoroutine 这个示例要放在 Example 里。
整理后的代码如下: Assets/QFramework/Framework/MonoBehaviourSimplify.cs
using
System
;
using
System
.
Collections
;
using
UnityEngine
;
namespace
QFramework
{
public
partial
class
MonoBehaviourSimplify
:
MonoBehaviour
{
public
void
Show
(
)
{
GameObjectSimplify
.
Show
(
gameObject
)
;
}
public
void
Hide
(
)
{
GameObjectSimplify
.
Hide
(
gameObject
)
;
}
public
void
Identity
(
)
{
TransformSimplify
.
Identity
(
transform
)
;
}
public
void
Delay
(
float
seconds
,
Action
onFinished
)
{
StartCoroutine
(
DelayCoroutine
(
seconds
,
onFinished
)
)
;
}
private
static
IEnumerator
DelayCoroutine
(
float
seconds
,
Action
onFinished
)
{
yield
return
new
WaitForSeconds
(
seconds
)
;
onFinished
(
)
;
}
}
}
Assets/QFramework/Example/8.定时功能/DelayWithCoroutine.cs
using
UnityEngine
;
namespace
QFramework
{
public
class
DelayWithCoroutine
:
MonoBehaviourSimplify
{
private
void
Start
(
)
{
Delay
(
5.0f
,
(
)
=>
{
UnityEditor
.
EditorApplication
.
isPlaying
=
false
;
}
)
;
}
#
if
UNITY_EDITOR
[
UnityEditor
.
MenuItem
(
"QFramework/Example/8.定时功能"
,
false
,
9
)
]
private
static
void
MenuClickd
(
)
{
UnityEditor
.
EditorApplication
.
isPlaying
=
true
;
new
GameObject
(
"DelayWithCoroutine"
)
.
AddComponent
<
DelayWithCoroutine
>
(
)
;
}
#
endif
protected
override
void
OnBeforeDestroy
(
)
{
}
}
}

第十二个示例
代码如下:
using
System
;
using
System
.
Collections
.
Generic
;
using
UnityEngine
;
namespace
QFramework
{
public
class
MsgDispatcher
{
private
static
Dictionary
<
string
,
Action
<
object
>
>
RegisteredMsgs
=
new
Dictionary
<
string
,
Action
<
object
>
>
(
)
;
public
static
void
Register
(
string
msgName
,
Action
<
object
>
onMsgReceived
)
{
if
(
!
RegisteredMsgs
.
ContainsKey
(
msgName
)
)
{
RegisteredMsgs
.
Add
(
msgName
,
_
=>
{
}
)
;
}
RegisteredMsgs
[
msgName
]
+=
onMsgReceived
;
}
public
static
void
UnRegisterAll
(
string
msgName
)
{
RegisteredMsgs
.
Remove
(
msgName
)
;
}
public
static
void
UnRegister
(
string
msgName
,
Action
<
object
>
onMsgReceived
)
{
if
(
RegisteredMsgs
.
ContainsKey
(
msgName
)
)
{
RegisteredMsgs
[
msgName
]
-=
onMsgReceived
;
}
}
public
static
void
Send
(
string
msgName
,
object
data
)
{
if
(
RegisteredMsgs
.
ContainsKey
(
msgName
)
)
{
RegisteredMsgs
[
msgName
]
(
data
)
;
}
}
#
if
UNITY_EDITOR
[
UnityEditor
.
MenuItem
(
"QFramework/12.简易消息机制"
,
false
,
13
)
]
#
endif
private
static
void
MenuClicked
(
)
{
// 全部清空，确保测试有效
UnRegisterAll
(
"消息1"
)
;
Register
(
"消息1"
,
OnMsgReceived
)
;
Register
(
"消息1"
,
OnMsgReceived
)
;
Send
(
"消息1"
,
"hello world"
)
;
UnRegister
(
"消息1"
,
OnMsgReceived
)
;
Send
(
"消息1"
,
"hello"
)
;
}
private
static
void
OnMsgReceived
(
object
data
)
{
Debug
.
LogFormat
(
"消息1:{0}"
,
data
)
;
}
}
}
MsgDispatcher 是能独立使用的类，所以要放到 Utils 里，其示例就放到 Example 里。
整理后如下: Assets/QFramework/Example/9.简易消息机制/MsgDispatcherExample.cs
using

)
]
#
endif
private
static
void
MenuClicked

{
// 全部清空，确保测试有效
