unity3d-游戏物体控制方法

键盘控制方向

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

public class Player : MonoBehaviour
{

public Rigidbody rd;
// Start is called before the first frame update
void Start()
{
    Debug.Log("1111111111111");
    //rd = GetComponent<Rigidbody>();
}

// Update is called once per frame
void Update()
{
  //transform.Rotate(Vector3.up * Time.deltaTime * 100);
    float f = Input.GetAxis("Horizontal");
    float v = Input.GetAxis("Vertical");
    rd.AddForce(new Vector3(f,0,v)*1);
}

}

给prefab添加标签，检测碰幢和销毁物体

private void OnCollisionEnter(Collision collision)
{
    if (collision.gameObject.tag=="food")
    {
        Destroy(collision.gameObject);
    }
}

触发检测

勾选collider中的istriigger，就变成了触发器
