将压缩包解压，将LowpolyTrump导入Unity

ji

将Anims目录下的trump_ip_anim_iddle01拖入hierarchy视图ImageTarget下，让它成为ImageTarget的子节点，选中修改component

第二步：Assets->Import Package->CrossPlatformInput

将MobileSingleStickControl拖入Hierarchy视图,删除下面的JumpButton
选中MobileJoystick修改参数

将Standard Assets下的CrossPlatformInput下的Prefabs中的MobileSingleStickControl拖入Hierarchy中

修改MobileJoystick的component

第三步：将trump的idle，walk动画的AnimationType 修改为Legacy

选中Anims下的Idle model,在Inspector中选中Rig选项卡

修改模型动画为Legacy

展开idle动画选中Take 001点击Inspector视图中的Edit

修改动画名称为idle，Wrap Mode为Loop，Walk动画同理

再次选中trump_lp_anim_iddle01，在Inspector中修改Animations Size为2，将walk拖入Element1

4.新建TrumpController.cs,拖入trump_lp_anim_iddle01中，成为其组件

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityStandardAssets.CrossPlatformInput;

public class TrumpController : MonoBehaviour {

    private Rigidbody rb;
    private Animation anim;

    // Use this for initialization
    void Start() {
        rb = GetComponent<Rigidbody>();
        anim = GetComponent<Animation>();
    }

    // Update is called once per frame
    void Update() {
        float x = CrossPlatformInputManager.GetAxis("Horizontal");
        float y = CrossPlatformInputManager.GetAxis("Vertical");
        Vector3 movement = new Vector3(x, 0, y);

        rb.velocity = movement * 4f;

        if (x != 0 && y != 0)
        {
            transform.eulerAngles = new Vector3(transform.eulerAngles.x, Mathf.Atan2(x, y) * Mathf.Rad2Deg, transform.eulerAngles.z);
        }

        if (x != 0 || y!=0)
        {
            anim.Play("walk");
        }
        else
        {
            anim.Play("idle");
        }
      
    }
}
