What is EasyTouch

EasyTouch allow you to quickly and easily develop actions based on a touchscreen or a mouse gesture. All major gestures are recognized such as touch, tap, double tape, twist, pinch.. and much more.

EasyTouch允许您快速轻松地开发基于触摸屏或鼠标手势的行为。

EasyTouch allows automatic detection of all gameobjects with collider on layers that you can set. To allow easy handling of the various elements that make up your scene

在预先设置的层上，EasyTouch自动检测所有gameobjects的碰撞体。很容易处理组成你的场景的各种元素。

EasyTouch is written in C# , it notifies you of an action on the touch screen or with mouse by firing events. The events are sent by delegate system for C #, or you can use EasyTouchTrigger component is you are not familiar with events.

EasyTouch是用c#编写的,它通知你在触摸屏或鼠标的行为是通过触发事件。发送事件可以通过C#的委托，也可以通过EasyTouchTrigger组件中所不熟悉的事件。

Each event passes a parameter class, with all the informations about the current action (position, angle, picked object …)

每个事件传递一个参数类，包含当前行为的所有信息。

Quick start

· Import EasyTouch package

· Right click on hierarchy view => EasyTouch => Add EasyTouch

· Create a new C# script MyFirstTouch

· Add these methods

// Subscribe to events

void OnEnable(){

EasyTouch.On_TouchStart += On_TouchStart;

}

// Unsubscribe

void OnDisable(){

EasyTouch.On_TouchStart -= On_TouchStart;

}

// Unsubscribe

void OnDestroy(){

EasyTouch.On_TouchStart -= On_TouchStart;

}

// Touch start event

public void On_TouchStart(Gesture gesture){

Debug.Log( "Touch in " + gesture.position);

}

· Create an empty gameObject, and name it Receiver.

· Add MyFirstTouch script to the gameObject Receiver.

· Run it in editor, and click on the screen

Quick start with auto-selection

· Import EasyTouch package

· Right click on hierarchy view => EasyTouch => Add EasyTouch

· Create a new C# script

· Add these methods

// Subscribe to events

void OnEnable(){

EasyTouch.On_TouchStart += On_TouchStart;

}

// Unsubscribe

void OnDisable(){

EasyTouch.On_TouchStart -= On_TouchStart;

}

// Unsubscribe

void OnDestroy(){

EasyTouch.On_TouchStart -= On_TouchStart;

}

// At the touch beginning

public void On_TouchStart(Gesture gesture){

// chack that we have touched the sphere

if (gesture.pickedObject == gameObject)

gameObject.renderer.material.color = new Color( Random.Range(0.0f,1.0f), Random.Range(0.0f,1.0f), Random.Range(0.0f,1.0f));

}

· Create a sphere and assign it a simple diffuse material

· Add script on the sphere

· Run it in editor, and click on the screen

EasyTouchTrigger

EasyTouchTrigger is a new component that allow you to easily & quickly use EasyTouch.It can be used instead or in addition to the conventional method by C# event.

This component allows you to call functions on GameObjects according EasyTouch events without writing a line of code.

How does it work?

ETT allows you to define the object which will receive a gesture and the object on which you want to execute a function. You still have to specify the function name, and if necessary the parameter to send.

How to use ETT (Look at video on Youtube)

· Select the gameobject to interact with the touch screen, or one that will serve as a scheduler. You can add as many as you like EasyTouchTrigger.

选择gameobject与触摸屏交互,或者将作为调度器。您可以添加多个你喜欢的EasyTouchTrigger。

· Add ETT component with Add Component button => Event => EasyTouch Trigger

 

· The component is now active on your gameobject

· You can now add EasyTouch event by clicking on Add new event. A context menu will display all available events

春节期间，学习了一下UGUI(Unity GUI)。

UGUI是Unity 4.6新增的功能，极大了弥补Unity GUI鸡肋: OnGUI.

 

学习UGUI最好的途径是系统的推理推理官方的UGUI的demo，如Drag And Drop、Menu 3D、Draggable Panel等，这些非常有嚼头，也可以学到很多东西。

 

demo很关键：源码，学习的动力，其他都是浮云。

 

• UGUI原生的UI组件有9个

  

 

• EventSystem

交互控件，默认只有一个事件，如Button自带一个OnClick事件，其他的事件，请通过EventTrigger添加。

添加UGUI组件后，一般会自带一个事件，如Button.OnClick()

其他的事件，通过添加Event Trigger添加：

或者通过写脚本，实现17个 UGUI-EventSystem 接口来实现。

 

• IPointerEnterHandler – OnPointerEnter – Called when a pointer enters the object
• IPointerExitHandler – OnPointerExit – Called when a pointer exits the object
• IPointerDownHandler – OnPointerDown – Called when a pointer is pressed on the object
• IPointerUpHandler – OnPointerUp – Called when a pointer is released (called on the original the pressed object)
• IPointerClickHandler – OnPointerClick – Called when a pointer is pressed and released on the same object
• IInitializePotentialDragHandler – OnInitializePotentialDrag – Called when a drag target is found, can be used to initialise values
• IBeginDragHandler – OnBeginDrag – Called on the drag object when dragging is about to begin
• IDragHandler – OnDrag – Called on the drag object when a drag is happening
• IEndDragHandler – OnEndDrag – Called on the drag object when a drag finishes
• IDropHandler – OnDrop – Called on the object where a drag finishes
• IScrollHandler – OnScroll – Called when a mouse wheel scrolls
• IUpdateSelectedHandler – OnUpdateSelected – Called on the selected object each tick
• ISelectHandler – OnSelect – Called when the object becomes the selected object
• IDeselectHandler – OnDeselect – Called on the selected object becomes deselected
• IMoveHandler – OnMove – Called when a move event occurs (left, right, up, down, ect)
• ISubmitHandler – OnSubmit – Called when the submit button is pressed
• ICancelHandler – OnCancel – Called when the cancel button is pressed

已知问题，在4.6.0 Win 7 64位系统下，ISubmitHandler我添加到InputField上，点击回车不会触发。

 

• Animation & Animator

UGUI的UI动画，可以由Unity 的新、老动画配合完成。

 

新动画	老动画
*.controller	*.anim
Animator状态机	Animation录制动画
设置条件变量	成对出现
Animator.SetBool()	Animation.Play()
同GameObject	同GameObject

 

为了简化常用动画，可通过DOTween脚本和UGUI结合，轻松的实现动画。

 

• 3种Canvas的用途

 

1 Screen Space OverLay 默认模式–静态的

2 Screen Space Camera NGUI默认效果，很酷UI，如ShowDialog等。

3 World Space — 3D对象上用，ToolTip、血条、HUD。

 

 

• Layout:Grid\H\V\Element

UGUI提供了4个Layout的组件，同时，结合Rect Transform的Anchors功能，方便设计复杂的UI嵌套。

布局要多练习，其核心思想和Web、流式布局类似，为了考虑多种屏幕尺寸，复杂UI要按照Grid划分好网格，再填充UI元素。

 

几个Tips：

• Rect Transform Reset ：rectT.anchoredPosition = Vector2.zero; //UGUI
• 一个习惯，把UI的控制代码挂到**Control上独立的一个EmptyGameObject上，如_AudioControl
• 在Image中的九宫格，如果设置Image Type：Sliced后失效，请导出你的场景为UnityPacage，再新建工程导入，则可成功九宫格了。
