收集整理的這篇文章主要介紹了
Unity3D_(游戏)2D坦克大战 像素版
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

2D坦克大戰? ? 像素版
游戲規則：
玩家通過上、下、左、右移動坦克，空格鍵發射子彈
敵人AI出身時朝向己方大本營(未防止游戲快速結束，心臟上方三個單位障礙物設為剛體)
當玩家被擊殺次數>=3 或 心臟被子彈擊穿 重新加載游戲場景
控制游戲每4秒發射一顆子彈(可自己做修改)

?
解決抖動問題

使用private void FixedUpdate()
FixedUpdate () 和 Update () 同：當MonoBehaviour啟用時，其在每一幀被調用。都是用來更新的異：Update()每一幀的時間不固定，即第一幀與第二幀的時間t1和第三幀與第四幀的時間t2不一定相同。FixedUpdate()每幀與每幀之間相差的時間是固定的.Update受當前渲染的物體影響，這與當前場景中正在被渲染的物體有關（比如人物的面數，個數等），有時快有時慢，幀率會變化，Update被調用的時間間隔就會發生變化。但是FixedUpdate則不受幀率的變化影響，它是以固定的時間間隔來被調用。所以一些物理屬性的更新操作應該放在FxiedUpdate中操作，比如Force，Collider，Rigidbody等。外設的操作也是，比如說鍵盤或者鼠標的輸入輸出Input，因為這樣GameObject的物理表現的更平滑，更接近現實。FixedUpdate的時間間隔可以在項目設置中更改，Edit->Project Setting->time 找到Fixed timestep。就可以修改了 FixedUpdate () 和 Update ()?
//監聽玩家水平軸輸入float h = Input.GetAxisRaw("Horizontal"); //返回-1 0 1transform.Translate(Vector3.right*h*moveSpeed*Time.fixedDeltaTime,Space.World);//監聽玩家垂直軸輸入float v = Input.GetAxisRaw("Vertical");transform.Translate(Vector3.up * v * moveSpeed * Time.fixedDeltaTime, Space.World);?
FixedUpdate()方法留空就行
private void FixedUpdate(){}?
?
using System.Collections; using System.Collections.Generic; using UnityEngine;public class Player : MonoBehaviour {public float moveSpeed = 3;private SpriteRenderer sr;public Sprite[] tankSprite; //上 右 下 左// Use this for initializationvoid Start () {sr = GetComponent<SpriteRenderer>();}// Update is called once per framevoid Update () {//監聽玩家水平軸輸入float h = Input.GetAxisRaw("Horizontal"); //返回-1 0 1transform.Translate(Vector3.right*h*moveSpeed*Time.fixedDeltaTime,Space.World);if (h < 0){sr.sprite = tankSprite[3];}else if (h>0){sr.sprite = tankSprite[1];}//監聽玩家垂直軸輸入float v = Input.GetAxisRaw("Vertical");transform.Translate(Vector3.up * v * moveSpeed * Time.fixedDeltaTime, Space.World);if (v < 0){sr.sprite = tankSprite[2];}else if (v > 0){sr.sprite = tankSprite[0];}}// private void FixedUpdate(){} } Player.cs?
解決玩家按方向鍵左右的同時按上下
在監聽玩家垂直軸輸入后對v方向按鍵進行判斷，如果為0則在Update()中直接返回
float v = Input.GetAxisRaw("Vertical");transform.Translate(Vector3.up * v * moveSpeed * Time.fixedDeltaTime, Space.World);if (v < 0){sr.sprite = tankSprite[2];}else if (v > 0){sr.sprite = tankSprite[0];}if(v!=0){return;}//監聽玩家水平軸輸入float h = Input.GetAxisRaw("Horizontal"); //返回-1 0 1transform.Translate(Vector3.right*h*moveSpeed*Time.fixedDeltaTime,Space.World);if (h < 0){sr.sprite = tankSprite[3];}else if (h>0){sr.sprite = tankSprite[1];}?
