Unity case RollABall (2) to create game players

 Create a sphere as the protagonist of the game, name it player, and also create a material ball:

Add a Rigidbody component to the object:

Next, write a script code to control the walking of game objects:

 

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class move : MonoBehaviour
{
    // Start is called before the first frame update
    public Rigidbody rd;  //定义一个属性 在面板上面就有了  就可以赋值刚体  也可以通过代码赋值

    void Start()
    {
        rd = GetComponent<Rigidbody>();


    }

    // Update is called once per frame
    void Update()
    {
        float h=Input.GetAxis("Horizontal");
        float v=Input.GetAxis("Vertical");
        rd.AddForce(new Vector3(h,0,v)*10);

    }
}
