Question

我的代码：

awk '$1 ~ strftime("%Y-%m-%d") {$1 = "today"} $1 ~ strftime("%Y-%m-%d",systime()+24*3600) {$1 = "tomorrow"} {print}'

Controller2D代码：

使用UnityEngine; 使用System.Collections;

[RequireComponent（typeof运算（BoxCollider2D））] 公共类Controller2D：MonoBehaviour {

using UnityEngine;
using System.Collections;

[RequireComponent(typeof(Controller2D))]
public class Player : MonoBehaviour
{

    public float jumpHeight = 4;
    public float timeToJumpApex = .4f;
    float accelerationTimeAirborne = .2f;
    float accelerationTimeGrounded = .1f;
    float moveSpeed = 6;

    float gravity;
    float jumpVelocity;
    Vector3 velocity;
    float velocityXSmoothing;

    Controller2D controller;

    void Start()
    {
        controller = GetComponent<Controller2D>();

        gravity = -(2 * jumpHeight) / Mathf.Pow(timeToJumpApex, 2);
        jumpVelocity = Mathf.Abs(gravity) * timeToJumpApex;
        print("Gravity: " + gravity + "  Jump Velocity: " + jumpVelocity);
    }

    void Update()
    {

        if (controller.collisions.above || controller.collisions.below)
        {
            velocity.y = 0;
        }

        Vector2 input = new Vector2(Input.GetAxisRaw("Horizontal"), Input.GetAxisRaw("Vertical"));

        if (Input.GetKeyDown(KeyCode.Space) && controller.collisions.below)
        {
            velocity.y = jumpVelocity;
        }

        float targetVelocityX = input.x * moveSpeed;
        velocity.x = Mathf.SmoothDamp(velocity.x, targetVelocityX, ref velocityXSmoothing, (controller.collisions.below) ? accelerationTimeGrounded : accelerationTimeAirborne);
        velocity.y += gravity * Time.deltaTime;
        controller.Move(velocity * Time.deltaTime);
    }
}

}

当我将鼠标悬停在“上方”和“下方”时，它会给我错误

c＃不包含扩展方法的定义，

谁能看到我做错了什么？

Answer 1

internal object collisions;

在此您将碰撞定义为对象。这意味着它没有上面或下面的布尔属性也许您需要定义一个名为collisions的新结构或类，并在上下定义内部或公共布尔属性。

c＃不包含定义，也没有扩展方法
