我只是想在我正在尝试编码的游戏中寻求NullReferenceException错误的帮助。这是我第二次使用Unity，所以我对它的工作方式并不熟悉。
错误消息发送给我的地方（遗漏了不必要的代码）：
public GameObject TilePrefab;
public GameObject PlayerPrefab;
public int mapSize = 11;
public List<List<Tile>> map = new List<List<Tile>>();
public List<PlayerControl> players;
bool isP1Turn = true;
void Awake(){
gObject = this;
}
void Start () {
generatePlayers ();
generateMap ();
}
void Update () {
if (isP1Turn)
players [0].turnUpdate ();
else
players [1].turnUpdate ();
}
//Right Here
public void nextTurn(){
if (isP1Turn) {
isP1Turn = false;
} else {
isP1Turn = true;
}
}
public void movePlayerChar(Tile t, int i){
/*if (t.gridPosition.x - players[0].GetComponent<int >() > 0 || t.gridPosition.y - UserControl.player.moveRange > 0) {
players[i].moveDestination = t.transform.position + 1.5f * Vector3.up;
}
void generatePlayers(){
players = new List<PlayerControl> ();
players.Add(((GameObject)Instantiate(PlayerPrefab, new Vector3(0 - Mathf.Floor(mapSize/2),1.5f, 0 + Mathf.Floor(mapSize/2)), Quaternion.Euler(new Vector3()))).GetComponent<PlayerControl>());
players.Add(((GameObject)Instantiate(PlayerPrefab, new Vector3((mapSize-1) - Mathf.Floor(mapSize/2),1.5f, -(mapSize-1) + Mathf.Floor(mapSize/2)), Quaternion.Euler(new Vector3()))).GetComponent<PlayerControl>());
}
但我认为错误源于此处，在PlayerControl类中：
public float mSpeed = 10.0f;
public Vector3 moveDestination;
void Start () {
moveDestination = transform.position;
transform.GetComponent<Renderer>().material.color = Color.blue;
}
void Update () {
}
void OnMouseEnter(){
transform.GetComponent<Renderer>().material.color = Color.cyan;
Debug.Log ("The cursor is on one of your units.");
}
void OnMouseExit(){
transform.GetComponent<Renderer> ().material.color = Color.blue;
}
public void turnUpdate(){
if (Vector3.Distance (moveDestination, transform.position) > 0.1f) {
transform.position += (moveDestination - transform.position).normalized * mSpeed * Time.deltaTime;
if(Vector3.Distance(moveDestination, transform.position) <= 0.1f){
transform.position = moveDestination;
GameManager.gObject.nextTurn();
}
}
}
我也相信我的'Tile'课程中的这种方法是相关的：
void OnMouseDown(){
if (GameManager.gObject.getTurn ()) {
GameManager.gObject.movePlayerChar (this, 0);
GameManager.gObject.nextTurn ();
}else{
GameManager.gObject.movePlayerChar(this, 1);
GameManager.gObject.nextTurn();
}
}
