1、搭建一个测试场景

2、建立画布设置移动按钮

3、编写脚本绑定按钮

AxisTouchButton ：
ButtonHandler ：

4、编写脚本绑定角色

原来的按键移动

修改为触摸按钮

5、导出为APK文件，手机下载进行测试

1、搭建一个测试场景

2、建立画布设置移动按钮

3、编写脚本绑定按钮

脚本资源来自：

 因为资源已经弃用了，资源商店搜是搜不到的。但是我之前下载过，所以有些还能用。

本次学习只需要以下代码即可：

左右移动按钮挂载同一个脚本：

AxisTouchButton ：

using System;
using UnityEngine;
using UnityEngine.EventSystems;namespace UnityStandardAssets.CrossPlatformInput
{public class AxisTouchButton : MonoBehaviour, IPointerDownHandler, IPointerUpHandler{// designed to work in a pair with another axis touch button// (typically with one having -1 and one having 1 axisValues)public string axisName = "Horizontal"; // The name of the axispublic float axisValue = 1; // The axis that the value haspublic float responseSpeed = 3; // The speed at which the axis touch button respondspublic float returnToCentreSpeed = 3; // The speed at which the button will return to its centreAxisTouchButton m_PairedWith; // Which button this one is paired withCrossPlatformInputManager.VirtualAxis m_Axis; // A reference to the virtual axis as it is in the cross platform inputvoid OnEnable(){if (!CrossPlatformInputManager.AxisExists(axisName)){// if the axis doesnt exist create a new one in cross platform inputm_Axis = new CrossPlatformInputManager.VirtualAxis(axisName);CrossPlatformInputManager.RegisterVirtualAxis(m_Axis);}else{m_Axis = CrossPlatformInputManager.VirtualAxisReference(axisName);}FindPairedButton();}void FindPairedButton(){// find the other button witch which this button should be paired// (it should have the same axisName)var otherAxisButtons = FindObjectsOfType(typeof(AxisTouchButton)) as AxisTouchButton[];if (otherAxisButtons != null){for (int i = 0; i < otherAxisButtons.Length; i++){if (otherAxisButtons[i].axisName == axisName && otherAxisButtons[i] != this){m_PairedWith = otherAxisButtons[i];}}}}void OnDisable(){// The object is disabled so remove it from the cross platform input systemm_Axis.Remove();}public void OnPointerDown(PointerEventData data){if (m_PairedWith == null){FindPairedButton();}// update the axis and record that the button has been pressed this framem_Axis.Update(Mathf.MoveTowards(m_Axis.GetValue, axisValue, responseSpeed * Time.deltaTime));}public void OnPointerUp(PointerEventData data){m_Axis.Update(Mathf.MoveTowards(m_Axis.GetValue, 0, responseSpeed * Time.deltaTime));}}
}

左边设置

右边设置

 跳跃按钮挂载这个脚本：

ButtonHandler ：

using System;
using UnityEngine;namespace UnityStandardAssets.CrossPlatformInput
{public class ButtonHandler : MonoBehaviour{public string Name;void OnEnable(){}public void SetDownState(){CrossPlatformInputManager.SetButtonDown(Name);}public void SetUpState(){CrossPlatformInputManager.SetButtonUp(Name);}public void SetAxisPositiveState(){CrossPlatformInputManager.SetAxisPositive(Name);}public void SetAxisNeutralState(){CrossPlatformInputManager.SetAxisZero(Name);}public void SetAxisNegativeState(){CrossPlatformInputManager.SetAxisNegative(Name);}public void Update(){}}
}

跳跃脚本设置

4、编写脚本绑定角色

原来的按键移动

using System.Collections;
using System.Collections.Generic;
using System.Collections.Specialized;
using UnityEngine;public class Char : MonoBehaviour
{private Rigidbody2D rb;private float moveSpeed;private float dirX;private bool facingRight = true;private Vector3 localScale;private void Start(){rb = GetComponent();localScale = transform.localScale;moveSpeed = 5f;}private void Update(){dirX = Input.GetAxisRaw("Horizontal") * moveSpeed;if (Input.GetButtonDown("Jump") && rb.velocity.y == 0)rb.AddForce(Vector2.up * 700f);}private void FixedUpdate(){rb.velocity = new Vector2(dirX, rb.velocity.y);}private void LateUpdate(){if (dirX > 0)facingRight = true;else if (dirX < 0)facingRight = false;if (((facingRight) && (localScale.x < 0)) || ((!facingRight) && (localScale.x > 0)))localScale.x *= -1;transform.localScale = localScale;}
}

修改为触摸按钮

using System.Collections;
using System.Collections.Generic;
using System.Collections.Specialized;
using UnityEngine;
using UnityStandardAssets.CrossPlatformInput;public class Character : MonoBehaviour
{private Rigidbody2D rb;private float moveSpeed;private Animator anim;private float dirX;private bool facingRight = true;private Vector3 localScale;private void Start(){rb = GetComponent();anim = GetComponent();localScale = transform.localScale;moveSpeed = 15f;}private void Update(){dirX = CrossPlatformInputManager.GetAxisRaw("Horizontal") * moveSpeed;if (CrossPlatformInputManager.GetButton("Jump")){// if ( && rb.velocity.y == 0)rb.AddForce(Vector2.up * 5f);anim.SetBool("isjump", true);}if (rb.velocity.y == 0)anim.SetBool("isjump", false);}private void FixedUpdate(){rb.velocity = new Vector2(dirX, rb.velocity.y);}private void LateUpdate(){if (dirX > 0)facingRight = true;else if (dirX < 0)facingRight = false;if (((facingRight) && (localScale.x < 0)) || ((!facingRight) && (localScale.x > 0)))localScale.x *= -1;transform.localScale = localScale;}
}

5、导出为APK文件，手机下载进行测试
