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
