C# 有没有一个简单的方法来制作2d unity游戏的动作脚本？

我需要你的帮助。我对C#相当了解，但不知道C#UnityEngine名称空间

Unity不支持足够的运动脚本，因为我不知道如何使用C#for Unity，所以我不想尝试编辑主代码

任何使用此命名空间的代码我都会感到困惑：

使用UnityEngine；

我对这样的变量感到困惑：

公共浮动速度=6.0F；
公共浮子跳跃速度=8.0F；
公共浮子重力=20.0F；
专用矢量3移动方向=矢量3.0；

这是一个简单的2d角色移动控制器。要使此脚本正常工作，您必须：

1。将此脚本分配给角色

public float speed;    
public float jumpHeight; 
Rigidbody2D rb; 

void Start(){
    //Get the rigidbody2d of the gameObject this script is assigned to.
    rb = GetComponent<Rigidbody2D>();
}

void Update() {
    //Determine the direction of the movement based on user input.
    float moveDir = Input.GetAxis("Horizontal");

    //Calculate the velocity of the gameObject.
    rb.velocity = new Vector2(moveDir * speed, rb.velocity.y);

    // Your jump code:
    if (Input.GetKeyDown(KeyCode.Space))
    {
        rb.velocity = new Vector2(rb.velocity.x, jumpHeight);
    }
}

2。向角色添加刚体2D

public float speed;    
public float jumpHeight; 
Rigidbody2D rb; 

void Start(){
    //Get the rigidbody2d of the gameObject this script is assigned to.
    rb = GetComponent<Rigidbody2D>();
}

void Update() {
    //Determine the direction of the movement based on user input.
    float moveDir = Input.GetAxis("Horizontal");

    //Calculate the velocity of the gameObject.
    rb.velocity = new Vector2(moveDir * speed, rb.velocity.y);

    // Your jump code:
    if (Input.GetKeyDown(KeyCode.Space))
    {
        rb.velocity = new Vector2(rb.velocity.x, jumpHeight);
    }
}

3。从角色的检查器中为speed和jumpHeight变量指定一个值

public float speed;    
public float jumpHeight; 
Rigidbody2D rb; 

void Start(){
    //Get the rigidbody2d of the gameObject this script is assigned to.
    rb = GetComponent<Rigidbody2D>();
}

void Update() {
    //Determine the direction of the movement based on user input.
    float moveDir = Input.GetAxis("Horizontal");

    //Calculate the velocity of the gameObject.
    rb.velocity = new Vector2(moveDir * speed, rb.velocity.y);

    // Your jump code:
    if (Input.GetKeyDown(KeyCode.Space))
    {
        rb.velocity = new Vector2(rb.velocity.x, jumpHeight);
    }
}

公共浮动速度；
公众浮标高度；
刚体2d rb；
void Start（）{
//获取此脚本分配给的游戏对象的RigidBy2D。
rb=GetComponent（）；
}
无效更新（）{
//根据用户输入确定移动方向。
float moveDir=Input.GetAxis（“水平”）；
//计算游戏对象的速度。
rb.velocity=新矢量2（moveDir*速度，rb.velocity.y）；
//您的跳转代码：
if（Input.GetKeyDown（KeyCode.Space））
{
rb.velocity=新矢量2（rb.velocity.x，跳跃高度）；
}
}
