Unity物体移动三种方法

球的移动方法一：

球的基本移动方法一：
transform.Translate,球只会平移前进
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class move : MonoBehaviour
{public float suDu;// Start is called before the first frame updatevoid Start(){suDu = 10.0f;}// Update is called once per framevoid Update(){if(Input.GetKey(KeyCode.W)){transform.Translate(Vector3.forward * suDu * Time.deltaTime);}if (Input.GetKey(KeyCode.S)){transform.Translate(Vector3.back * suDu * Time.deltaTime);}if (Input.GetKey(KeyCode.A)){transform.Translate(Vector3.left * suDu * Time.deltaTime);}if (Input.GetKey(KeyCode.D)){transform.Translate(Vector3.right * suDu * Time.deltaTime);}}private  void OnTriggerEnter(Collider other){Destroy(other.gameObject);}
}

球的移动方法（二）：

添加力，球会翻转前进
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class move : MonoBehaviour
{public float suDu;public Rigidbody rg;// Start is called before the first frame updatevoid Start(){suDu = 12.0f;rg = GetComponent<Rigidbody>();}// Update is called once per framevoid Update(){if(Input.GetKey(KeyCode.S)){rg.AddForce(Vector3.right * suDu * Time.deltaTime);//transform.Translate(Vector3.right * suDu * Time.deltaTime);}if (Input.GetKey(KeyCode.W)){rg.AddForce(Vector3.left * suDu * Time.deltaTime);//transform.Translate(Vector3.left * suDu * Time.deltaTime);}if (Input.GetKey(KeyCode.D)){rg.AddForce(Vector3.forward * suDu * Time.deltaTime);//transform.Translate(Vector3.forward * suDu * Time.deltaTime);}if (Input.GetKey(KeyCode.A)){rg.AddForce(Vector3.back * suDu * Time.deltaTime);//transform.Translate(Vector3.back * suDu * Time.deltaTime);}}private  void OnTriggerEnter(Collider other){Destroy(other.gameObject);}
}

球的移动方法（三）：
利用GetAxis方向键控制移动，Horizontal控制水平方向，Vertical控制垂直；

public float speed=120f;
public float  h,v;
void Update()
{
h=Input.GetAxis("Horizontal");
v=Input.GetAxis("Vertical");
transform.Translate(new Vector3(h,0,v)*speed*Time.deltaTime);
}
