Unity-EasyTouch插件之Two Finger

今天，我们来学习下多手指触摸屏幕的事件，分别有挤压（缩放），挤压（旋转）

挤压（缩放）：

在easytouch中，双手指挤压缩放的英文为Pinch

好了今天我们的测试是双手指挤压对物体进行缩放。我们测试的是Cube。

在easytouch中，分别有挤入（PinchIn）和挤出（PinchOut）这这两个对立的触屏手势。

using UnityEngine;
using System.Collections;

public class TouchTest : MonoBehaviour {
void OnEnable(){
EasyTouch.On_PinchIn += On_PinchIn;//挤入
EasyTouch.On_PinchOut += On_PinchOut;//挤出
EasyTouch.On_PinchEnd += On_PinchEnd;//挤压结束
}

void OnDisable(){
UnsubscribeEvent();
}

void OnDestroy(){
UnsubscribeEvent();
}

// Unsubscribe to events
void UnsubscribeEvent(){
EasyTouch.On_PinchIn -= On_PinchIn;
EasyTouch.On_PinchOut -= On_PinchOut;
EasyTouch.On_PinchEnd -= On_PinchEnd;
}

void Start(){
}
private void On_PinchIn(Gesture gesture){

if (gesture.pickObject == gameObject){

float zoom = Time.deltaTime * gesture.deltaPinch;

Vector3 scale = transform.localScale ;
transform.localScale = new Vector3( scale.x - zoom, scale.y -zoom, scale.z-zoom);
}
}

private void On_PinchOut(Gesture gesture){
if (gesture.pickObject == gameObject){
float zoom = Time.deltaTime * gesture.deltaPinch;

Vector3  scale = transform.localScale ;
transform.localScale = new Vector3( scale.x + zoom, scale.y +zoom,scale.z+zoom);

}
}
private void On_PinchEnd(Gesture gesture){

if (gesture.pickObject == gameObject){
print ("End");
}

}
}

　　这里注意一下，挤压的时候两个手指必须都接触到GameObject，不能一只有一只没有。

可能有些小伙伴还不知道怎么在电脑上测试，在easytoucjh的属性面板里面，我们发现按下Left Alt是默认的Pinch和Twist的按键。

挤压（旋转）：

在easytouch中双手挤压旋转对应的英文为Twist

using UnityEngine;
using System.Collections;

public class TouchTest : MonoBehaviour {
void OnEnable(){
EasyTouch.On_Twist += On_Twist;
EasyTouch.On_TwistEnd += On_TwistEnd;
}

void OnDisable(){
UnsubscribeEvent();
}

void OnDestroy(){
UnsubscribeEvent();
}

// Unsubscribe to events
void UnsubscribeEvent(){
EasyTouch.On_Twist -= On_Twist;
EasyTouch.On_TwistEnd -= On_TwistEnd;
}

void Start(){

}
private void On_Twist(Gesture gesture)
{
if (gesture.pickObject == gameObject)
{
print(gesture.twistAngle);
transform.Rotate(new Vector3(0,0,gesture.twistAngle));//旋转挤压的角度,
}
}
private void On_TwistEnd(Gesture gesture)
{
if (gesture.pickObject == gameObject)
{
print("End");
}
}
}
