Question

我对团结3d和c锐利全新。我正在设计一个球体正在追逐立方体的程序。我尝试过，但它显示出一些错误。

控制台出错：

Assets/chaserr.cs(8,40): error CS0019: Operator `-' cannot be applied to operands of type `UnityEngine.Transform' and `UnityEngine.Vector3'
Assets/chaserr.cs(11,38): error CS0019: Operator `+' cannot be applied to operands of type `UnityEngine.Vector3' and `float'
Assets/chaserr.cs(11,27): error CS1502: The best overloaded method match for `UnityEngine.Transform.Translate(UnityEngine.Vector3)' has some invalid arguments
Assets/chaserr.cs(11,27): error CS1503: Argument `#1' cannot convert `object' expression to type `UnityEngine.Vector3'

Chaserr.cs

using UnityEngine;
using System.Collections;

public class chaserr : MonoBehaviour {
    public Transform target;
    float speed = 8;
    void Update () {
        Vector3 displacement = target - transform.position;
        Vector3 direction = displacement.normalized;
        Vector3 velocity = direction * speed;
        transform.Translate (velocity + Time.deltaTime);
    }
}

move.cs

using UnityEngine;
using System.Collections;

public class move : MonoBehaviour {
    float speed = 10;
    void Update () {
        Vector3 input = new Vector3 (Input.GetAxisRaw ("Horizontal"), 0, Input.GetAxisRaw ("Vertical"));
        Vector3 direction = input.normalized;
        Vector3 velocity = direction * speed;
        Vector3 moveAmount = velocity * Time.deltaTime;
        transform.Translate (moveAmount);

    }
}

Answer 1

您可以使用Rigidbody（或2D游戏的Rigidbody2D）更改GameObject的速度。

首先将Rigidbody组件添加到GameObject中;

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public Rigidbody rigid;
    Vector3 yourVelocityVariable;

    void Start() {
        rigid = GetComponent<Rigidbody>();
    }
    void FixedUpdate() {
        rigid.velocity = yourVelocityVariable;            
    }
}

Answer 2

而不是

Vector3 displacement = target - transform.position;

使用

Vector3 displacement = target.position - transform.position;

和

而不是

velocity + Time.deltaTime

使用

velocity * Time.deltaTime
