使用向左/向右滑动在Subway Surf中像游戏一样移动玩家 [英] Moving player in Subway Surf like game using left/right swipe

问题描述

我正在开发无尽的亚军游戏，例如Unity中的地铁冲浪者. 我想在向左或向右滑动时平稳地移动播放器. 怎么办 这是我的代码:

I am developing endless runner game like subway surfer in Unity. I want to move my player, smoothly on swipe left or right. How can do it? Here is my code:

using UnityEngine;
using System.Collections;

public class SwipeScript3 : MonoBehaviour {

private Touch initialTouch = new Touch();
private float distance = 0;
private bool hasSwiped = false;
//Quaternion targetx = Quaternion.Euler(0, -3f, 0);
//Quaternion targety = Quaternion.Euler(0, 3f, 0);

void FixedUpdate()
{
    foreach(Touch t in Input.touches)
    {
        if (t.phase == TouchPhase.Began)
        {
            initialTouch = t;
        }
        else if (t.phase == TouchPhase.Moved && !hasSwiped)
        {
            float deltaX = initialTouch.position.x - t.position.x;
            float deltaY = initialTouch.position.y - t.position.y;
            distance = Mathf.Sqrt((deltaX * deltaX) + (deltaY * deltaY));
            bool swipedSideways = Mathf.Abs(deltaX) > Mathf.Abs(deltaY);

            if (distance > 50f)
            {
                if (swipedSideways && deltaX > 0) //swiped left
                {

                    //transform.rotation = Quaternion.Slerp (transform.rotation, targetx, Time.deltaTime * 0.8f);
                    this.transform.Rotate(new Vector3(0, -3f, 0)*Time.deltaTime);
                    //transform.position = Vector3.Lerp (transform.position,new Vector3(transform.position.x+5f,transform.position.y,transform.position.z),Time.deltaTime*2f );
                    transform.position = Vector3.Lerp (transform.position, new Vector3 (transform.position.x - 5f, transform.position.y, transform.position.z), Time.deltaTime * 5f);
                }
                else if (swipedSideways && deltaX <= 0) //swiped right
                {
                    //transform.rotation = Quaternion.Slerp (transform.rotation, targety, Time.deltaTime * 0.8f);
                    this.transform.Rotate(new Vector3(0, 3f, 0)*Time.deltaTime);
                    //transform.position = Vector3.Lerp (transform.position, new Vector3 (transform.position.x - 5f, transform.position.y, transform.position.z), Time.deltaTime * f);
                    transform.position = Vector3.Lerp (transform.position,new Vector3(transform.position.x+5f,transform.position.y,transform.position.z),Time.deltaTime*5f );
                }
                else if (!swipedSideways && deltaY > 0) //swiped down
                {
                    //this.transform.Rotate(new Vector3(0, 2f, 0));
                    transform.position = Vector3.Lerp (transform.position,new Vector3(transform.position.x,transform.position.y,transform.position.z-5f),Time.deltaTime*2f );
                }
                else if (!swipedSideways && deltaY <= 0)  //swiped up
                {
                    this.GetComponent<Rigidbody>().velocity = new Vector3(this.GetComponent<Rigidbody>().velocity.x, 0, this.GetComponent<Rigidbody>().velocity.z);
                    this.GetComponent<Rigidbody>().AddForce(new Vector3(0, 400f, 0));
                    Debug.Log ("Swiped Up");
                }

                hasSwiped = true;
            }

        }
        else if (t.phase == TouchPhase.Ended)
        {
            initialTouch = new Touch();
            hasSwiped = false;
        }
    }
}
}

推荐答案

您可以使用Vector3.Slerp(Vector3 StartPosition, Vector3 DestinationPosition, float Number)

• Number在0和1之间，它指示对象在StartPosition和DestinationPosition之间的位置.

• Number is between 0 and 1 and it indicates where will be the position of your object between StartPosition and DestinationPosition.

让我们说Number = 0.0f;:您的对象将位于StartPosition.

Lets say Number = 0.0f;: your object will be at StartPosition.

如果为Number = 0.5f;:您的对象将位于StartPosition和DestinationPosition之间.

If Number = 0.5f;: your object will be between StartPosition and DestinationPosition.

执行滑动操作时，您需要将Number的值从0增加到1.

You need to increase the Number value from 0 to 1 when swipe action is performed.

增加"Number"值的速度越快，对象向目的地"移动的速度就越快.

The faster you increase the "Number" value, the faster your object will move towards Destination.

您应该在滑动操作开始时将您设置为StartPosition一次，而不要在Vector3.Slerp()函数中反复输入transform.position.

You should set you StartPosition once when the swipe action begins, not give your transform.position repeatedly in your Vector3.Slerp() function.

您可以在Unity文档中的此处中找到示例.

You can find an example here in Unity Docs.
