我是编程的新手，这是Collision Physics＆Rigidbody Movement的代码，但是当我保存脚本时，unity证明了这一点。问题在第45和50行。
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Move : MonoBehaviour {
public float moveSpeed;
private Animator anim;
private Rigidbody2D myRigidbody;
private bool playerMoving;
private Vector2 lastMove;
// Use this for initialization
void Start () {
anim = GetComponent<Animator>();
myRigidbody = GetComponent<Rigidbody2D>();
}
// Update is called once per frame
void Update () {
playerMoving = false;
if(Input.GetAxisRaw("Horizontal") > 0.5f || Input.GetAxisRaw("Horizontal") < -0.5f)
{
//transform.Translate (new Vector3(Input.GetAxisRaw("Horizontal") * moveSpeed * Time.deltaTime, 0f, 0f));
myRigidbody.velocity = new Vector2(Input.GetAxisRaw("Horizontal") * moveSpeed, myRigidbody.velocity.y);
playerMoving = true;
lastMove = new Vector2(Input.GetAxisRaw("Horizontal"), 0f );
}
if(Input.GetAxisRaw("Vertical") > 0.5f || Input.GetAxisRaw("Vertical") < -0.5f )
{
//transform.Translate (new Vector3(0f, Input.GetAxisRaw("Vertical") * moveSpeed * Time.deltaTime, 0f));
myRigidbody.velocity = new Vector2(myRigidbody.velocity.x, Input.GetAxisRaw("Vertical") * moveSpeed);
playerMoving = true;
lastMove = new Vector2(0f, Input.GetAxisRaw("Vertical"));
}
If(Input.GetAxisRaw("Horizontal") < 0.5f && Input.GetAxisRaw("Horizontal") > -0.5f)
{
myRigidbody.velocity = new Vector2(0f, myRigidbody.velocity.y);
}
If(Input.GetAxisRaw("Vertical") < 0.5f && Input.GetAxisRaw("Vertical") > -0.5f )
{
myRigidbody.velocity = new Vector2(myRigidbody.velocity.x, 0f);
}
anim.SetFloat("MoveX", Input.GetAxisRaw("Horizontal"));
anim.SetFloat("MoveY", Input.GetAxisRaw("Vertical"));
anim.SetBool("PlayerMoving", playerMoving);
anim.SetFloat("LastMoveX", lastMove.x);
anim.SetFloat("LastMoveY", lastMove.y);
}
}
答案 0 :(得分：2)
这两个：
this是方法调用，因为您写的是onDeleteClick(e,data) {
e.preventDefault();
this.dataToBeDeleted = data;
this.setState({
showDeleteDialog: true
});
}

而不是If(Input.GetAxisRaw("Horizontal") < 0.5f && Input.GetAxisRaw("Horizontal") > -0.5f)
...
If(Input.GetAxisRaw("Vertical") < 0.5f && Input.GetAxisRaw("Vertical") > -0.5f )
。
C＃编译器区分大小写，if语句的C＃关键字为If，而不是if。
因此，编译器无法理解为什么您在方法调用后加上一个块而不是一个分号：
if可以很容易地使它变得更清楚：
If因此，将您的If(...) { ... }
语句更改为Console.WriteLine("Test") { ... }
，它应该会更好一些。
