Question

我有一个2D游戏，我需要在设备倾斜时在x轴上移动玩家rigidbody2D。我下面的代码是我认为应该工作的，但事实并非如此。玩家根本不动。我做错了什么，为什么？

Vector3 dir = Vector3.zero;
        dir.x = Input.acceleration.y;
        if (dir.sqrMagnitude > 1)
            dir.Normalize();

        dir *= Time.deltaTime;
        anim.SetFloat("Speed", Mathf.Abs(dir.x));
        rigidbody2D.velocity = new Vector2 (dir.x * tiltSpeed, rigidbody2D.velocity.y);

以下完整代码

using UnityEngine;
using System.Collections;

public class CharacterControllerScript : MonoBehaviour {

public float maxSpeed = 10f;
bool facingRight = true;
public float tiltSpeed = 10f;

Animator anim;

// Use this for initialization
void Start () {
    anim = GetComponent<Animator>();
}

// Update is called once per frame
void FixedUpdate () {
    // Set animation
    if ((Application.platform != RuntimePlatform.Android) || (Application.platform != RuntimePlatform.IPhonePlayer)){
        float move = Input.GetAxis ("Horizontal");
        anim.SetFloat("Speed", Mathf.Abs(move));
        rigidbody2D.velocity = new Vector2 (move * maxSpeed, rigidbody2D.velocity.y);
        // Decide what way animation moving
        if (move > 0 && !facingRight)
            Flip ();
        else if (move < 0 && facingRight)
            Flip ();
    }
    else {
        Vector3 dir = Vector3.zero;
        dir.x = Input.acceleration.y;
        if (dir.sqrMagnitude > 1)
            dir.Normalize();

        dir *= Time.deltaTime;
        anim.SetFloat("Speed", Mathf.Abs(dir.x));
        rigidbody2D.velocity = new Vector2 (dir.x * tiltSpeed, rigidbody2D.velocity.y);
        // Decide what way animation moving
        if (move > 0 && !facingRight)
            Flip ();
        else if (move < 0 && facingRight)
            Flip ();
    }
}

void Flip () {
    facingRight = !facingRight;
    Vector3 thescale = transform.localScale;
    thescale.x *= -1;
    transform.localScale = thescale;
}
}

我希望自从您几个月前发布以来，这个答案对您仍然有用

我认为您的代码将始终通过第一个案例。你应该替换

(Application.platform != RuntimePlatform.Android) || (Application.platform != RuntimePlatform.IPhonePlayer)

通过

(Application.platform != RuntimePlatform.Android) && (Application.platform != RuntimePlatform.IPhonePlayer)

因为它们不能同时成为现实
