Unity3d 触摸控制unity 2D

我有一个名为

PlayerCharacter

的脚本来控制Unity 2D平台上的玩家。它很完美，像往常一样工作

using UnityEngine;

public class PlayerCharacter : MonoBehaviour
{
    public float speed = 1.0f;
    public string axisName = "Horizontal";
    private Animator anim;
    public string jumpButton = "Fire1";
    public float jumpPower = 10.0f;
    public float minJumpDelay = 0.5f;
    public Transform[] groundChecks;

    private float jumpTime = 0.0f;
    private Transform currentPlatform = null;
    private Vector3 lastPlatformPosition = Vector3.zero;
    private Vector3 currentPlatformDelta = Vector3.zero;


    // Use this for initialization
    void Start ()
    {
        anim = gameObject.GetComponent<Animator>();
    }


    // Update is called once per frame
    void Update ()
    {
        //Left and right movement
        anim.SetFloat("Speed", Mathf.Abs(Input.GetAxis(axisName)));
        if(Input.GetAxis(axisName) < 0)
        {
        Vector3 newScale = transform.localScale;
        newScale.x = -1.0f;
        transform.localScale = newScale;
        Debug.Log("Move to left");
        }
        else if(Input.GetAxis(axisName) > 0)
        {
        Vector3 newScale = transform.localScale;
        newScale.x = 1.0f;
        transform.localScale = newScale;
        Debug.Log ("Move to Right");
        }
        transform.position += transform.right*Input.GetAxis(axisName)*speed*Time.deltaTime;

        //Jump logic
        bool grounded = false;
        foreach(Transform groundCheck in groundChecks)
        {
            grounded |= Physics2D.Linecast(transform.position, groundCheck.position, 1 << LayerMask.NameToLayer("Ground"));
        }
        anim.SetBool("Grounded", grounded);
        if(jumpTime > 0)
        {
            jumpTime -= Time.deltaTime;
        }
        if(Input.GetButton("jumpButton")  && anim.GetBool("Grounded") )

        {
            anim.SetBool("Jump",true);
            rigidbody2D.AddForce(transform.up*jumpPower);
            jumpTime = minJumpDelay;
        }
        if(anim.GetBool("Grounded") && jumpTime <= 0)
        {
            anim.SetBool("Jump",false);
        }
        //Moving platform logic
        //Check what platform we are on
        List<Transform> platforms = new List<Transform>();
        bool onSamePlatform = false;
        foreach(Transform groundCheck in groundChecks)
        {
            RaycastHit2D hit = Physics2D.Linecast(transform.position, groundCheck.position, 1 << LayerMask.NameToLayer("Ground"));
            if(hit.transform != null)
            {
                platforms.Add(hit.transform);
                if(currentPlatform == hit.transform)
                {
                    onSamePlatform = true;
                }
            }
        }

        if(!onSamePlatform)
        {
            foreach(Transform platform in platforms)
            {
                currentPlatform = platform;
                lastPlatformPosition = currentPlatform.position;
            }
        }
    }

    void LateUpdate()
    {
        if(currentPlatform != null)
        {
            //Determine how far platform has moved
            currentPlatformDelta = currentPlatform.position - lastPlatformPosition;

            lastPlatformPosition = currentPlatform.position;
        }
        if(currentPlatform != null)
        {
            //Move with the platform
            transform.position += currentPlatformDelta;
        }
    }   
}

但是我不知道如何实现教程中的脚本（

TouchControls

），并将其分配给我的播放器控制脚本（

PlayerCharacter

）。如何组合这两个脚本，以便玩家可以使用可触摸控件控制它？

最好不要将触摸控件从touchcontrols教程拖动到playercontroller，相反，使用touchcontrols教程脚本作为模板

因为您的playercontroller在其输入中使用浮动，例如moveleft=50.0f；触摸控件使用moveleft=true

这些脚本彼此非常不同，只是合并和工作

因此，在touchcontrols中，保持更新功能不变， 并且仅使用控件逻辑更新fixedupate函数 更新void，可以说是右、左、上、下的条件控制器。 它还将处理触摸屏的实际输入

固定更新可以控制playercontroller拥有的某些功能，例如 在触摸标记的对象或类似对象时应用力。

---

更新只执行输入条件，好的建议是将更新触摸代码包装在其自身的功能中，这样更新不仅是触摸，而且是其他游戏逻辑相关代码。

在更改正确的部分时，您应该搜索并使用复制玩家控制器内的触摸控制脚本。例如，您应该使用

Input.GetKeyDown

而不是

Input.GetTouch

，但这取决于您正在创建的游戏。您应该注意该代码并更改某些部分

您到底是如何在游戏中实现触摸控制的？左/右/跳转是否与某些滑动相对应？或者当你触摸屏幕上的某个点时，它们会触发吗？左、右和跳跃。嗯，出于某种目的，我更喜欢使用GuitTexture作为触摸控制器，就像我在上面发布的一样。但我不知道如何实施它啊，对我来说似乎很难。如果它不适合，有没有其他方法使touchcontroll适合

PlayerCharacter

code？你可以看看unity附带的移动设备标准资产，它们有一些标准控件，适用于第三人称和第一人称，我会用它来设置我的角色，然后打开源代码，随着时间的推移慢慢修改它，以满足我在游戏开发过程中的需要
