1091226 長壓住按鈕控制器

安裝時將這個腳本拖曳到Image底下,在按鈕選自己這個Image物件
功能選LongPressFunction

原理:
設定一個移動方向的運算子
在按下按鈕的時候會送出一個數字到運算子
update去偵測該運算子的數字,去作出對應方向的移動


using UnityEngine;
using UnityEngine.UI;
using UnityEngine.Events;
using UnityEngine.EventSystems;

public class 腳本按鈕 : MonoBehaviour, IPointerDownHandler, IPointerUpHandler

{
  public GameObject controller1 ; //宣告要被遙控的對象
  public Text counttext1 ; //宣告要用來辨識方向的運算子
  public float PressDownTimer; //按下幾秒觸發
  private bool PressDown; //按下
  public UnityEvent onLongClick; //開啟Inspector觸發事件
  [SerializeField]
  public float HoldTime;

  //按下按鈕
  public void OnPointerDown(PointerEventData eventData){
    PressDown = true;
    Debug.Log("PressDown");
    counttext1.text= "1";
  }
  //按鈕彈起
  public void OnPointerUp(PointerEventData eventData){
    Reset();
    Debug.Log("PressUp");
    counttext1.text= "0";
  }
  //當按下按鈕 PressDown = true 時計時
  void Update(){
    if (PressDown == true){
      PressDownTimer += Time.deltaTime;
      if (PressDownTimer >= HoldTime){
        if (onLongClick != null){
          onLongClick.Invoke();
        }
        Reset();
      }
    }

    if(counttext1.text == "1")
controller1.transform.position += new Vector3(0.1f,0,0); //如果運算子為1,往右走

    if(counttext1.text == "0")
print(" No Data") ;

  }
  //當PressUp的時候重製計算時間
  private void Reset(){
    PressDown = false;
    PressDownTimer = 0;
  }
  //觸發後執行的功能
  public void LongPressFuntion() { 
    Debug.Log("觸發後執行的功能");
  }
}
