主要內容：1、最終呈現效果 2、程式碼大概邏輯 3、程式碼塊
1、目前效果：
2、程式碼大概邏輯
3、程式碼塊
（1）掛在主攝像機
using System.Collections; using System.Collections.Generic; using UnityEngine; public class Axes { public static LandState landState = LandState.None; public static int direction = 0; public const int axisX = 0;public const int axisY = 1; } public class Cubes { public static Transform current; public static Transform target; public static int id = 0; } public class InitCube : MonoBehaviour { int direction = 0; int index = 0; float randomColor = 0; List<GameObject> cubeList = newList<GameObject>(); GameObject cubePrefab;
private void OnDisable() { //事件登出 JumpLeap.AfterJump -= RandInitCube; } private void Start() { //事件註冊 JumpLeap.AfterJump += RandInitCube; Axes.direction = direction; //盒子池 cubePrefab = Resources.Load<GameObject>("Cube"); for (int i = 0; i < 6; i++) { cubeList.Add(GameObject.Instantiate(cubePrefab)); cubeList[i].SetActive(false); } SetCubePosAndActive(Vector3.zero); SetCubePosAndActive(new Vector3(2,0,0)); } //重新開始遊戲 public void RestartGame() { index = 0; Cubes.id = 0; Axes.direction = 0; for (int i = 0; i < 6; i++) { cubeList[i].SetActive(false); } SetCubePosAndActive(Vector3.zero); SetCubePosAndActive(new Vector3(2, 0, 0)); GameObject.FindGameObjectWithTag("Player").transform.position = new Vector3(0, 3, 0); GameObject.FindGameObjectWithTag("Player").transform.rotation = Quaternion.identity; } //設定cube 位置和狀態 public void SetCubePosAndActive(Vector3 pos) { cubeList[index].SetActive(true); cubeList[index].transform.position = pos; cubeList[index].GetComponent<MeshRenderer>().material.color = new Color(Random.Range(0f, 1f), Random.Range(0f, 1f), Random.Range(0f, 1f), 1); int ii = index - 1; if (ii < 0) { ii = cubeList.Count - 1; } Cubes.current = cubeList[ii].transform; Cubes.target = cubeList[index].transform; for (int i = 0; i < cubeList.Count; i++) { cubeList[i].tag = "Untagged"; if (i == ii) { Cubes.current.tag = "Current"; } if (i == index) { Cubes.target.tag = "Target"; } } index++; if (index == cubeList.Count) { index = 0; } } //隨機生成cube public void RandInitCube() { if (Cubes.current == JumpLeap._instance.colliderTrans) { return; } Axes.direction = Random.Range(0, 2); direction = Axes.direction; float distance = Random.Range(1.5f, 2.5f); if (Axes.direction == Axes.axisX) { SetCubePosAndActive(new Vector3(Cubes.target.position.x + distance, Cubes.target.position.y, Cubes.target.position.z)); } if (Axes.direction == Axes.axisY) { SetCubePosAndActive(new Vector3(Cubes.target.position.x, Cubes.target.position.y, Cubes.target.position.z + distance)); } } }
（2）掛在棋子上

（3）掛在Canvas上
