如何在平台游戏中添加触摸按钮？

Question

我正在为 android 开发 2D 视频游戏，我唯一需要完成的就是制作触摸控件。视频游戏仅包含左右移动和跳跃（如 MarioBros）。我已经在画布上创建了按钮，我只需要脚本，非常感谢您的帮助，我附上我的播放器代码，以防您帮助我进行修改。

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using UnityEngine.SceneManagement;


public class PlayerController : MonoBehaviour
{
    public float jumpPower = 15f;
    private bool jump;
    public bool grounded;
    private Rigidbody2D rb2d;
    private Animator anim;
    private GameObject healthbar;
    public GameObject panelGameOver;



    // Start is called before the first frame update
    void Start()
    {
        rb2d = GetComponent<Rigidbody2D>();
        anim = GetComponent<Animator>();

        healthbar = GameObject.Find("Healthbar");
    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Space) && grounded)
        {
            jump = true;
        }
        anim.SetBool("Grounded", grounded);
    }

    void FixedUpdate()
    {

        {
            if (Input.GetKey(KeyCode.RightArrow))
            {
                if (GetComponent<SpriteRenderer>().flipX == true)
                {
                    GetComponent<SpriteRenderer>().flipX = false;
                }
                GetComponent<Animator>().SetBool("Correr", true);
                transform.Translate(0.1f, 0, 0);
            }
            if (Input.GetKey(KeyCode.LeftArrow))
            {
                if (GetComponent<SpriteRenderer>().flipX == false)
                {
                    GetComponent<SpriteRenderer>().flipX = true;
                }
                GetComponent<Animator>().SetBool("Correr", true);
                transform.Translate(-0.1f, 0, 0);
            }
            if (Input.GetKeyUp(KeyCode.LeftArrow) || Input.GetKeyUp(KeyCode.RightArrow))
            {
                GetComponent<Animator>().SetBool("Correr", false);
            }
            //Saltar
            if (jump)
            {
                rb2d.AddForce(Vector2.up * jumpPower, ForceMode2D.Impulse);
                jump = false;
            }

        }






        //
    }
    public void EnemyJump()
    {
        jump = true;


    }

    public void EnemyJumpB()
    {
        healthbar.SendMessage("TakeDamage", 30);
        jump = true;

    }

}

Answer 1

你可以在你的 UI 按钮上附加（或者你已经附加了一个）Button 组件，你可以像这样使用它们：

using UnityEngine;
using UnityEngine.UI;
using System.Collections;

public class ClickExample : MonoBehaviour {
    public Button yourButton;

    void Start () {
        Button btn = yourButton.GetComponent<Button>();
        btn.onClick.AddListener(TaskOnClick);
    }

    void TaskOnClick(){
        Debug.Log ("You have clicked the button!");
    }
}

您在 Update() 和 FixedUpdate() 脚本中的所有“if”语句都可以替换为适当的“TaskOnClick()”函数（以一种很好的方式命名它们

“如果”的：

public Button leftButton;

private void OnLeftButton() {
    if (GetComponent<SpriteRenderer>().flipX == false) {
        GetComponent<SpriteRenderer>().flipX = true;
    }
    GetComponent<Animator>().SetBool("Correr", true);
    transform.Translate(-0.1f, 0, 0);
}

private void Awake() {
    this.leftButton.onClick.AddListener(OnLeftButton)
}
