Unity 2D，游戏对象到中心

Question

I need Help, I'm doing a smaller puzzle game but I have trouble getting the playing field to the center. Playing field is still on the bottom/left I tried to fix it using the forum but nothing happened. Thanks for your help.

Problem

GameBoard.cs

using UnityEngine;
using System.Collections;

public class GameBoard : MonoBehaviour {

public int m_size;
public GameObject m_puzzlePiece;
public GameObject buttonNext;

private PuzzleSection[,] m_puzzle;
private PuzzleSection m_puzzleSelection;

public int m_randomPasses = 12;



void Start()
{
    GameObject temp;
    m_puzzle = new PuzzleSection[m_size, m_size];


    for (int i=0; i< m_size; i++)
    {
        for (int j=0; j< m_size; j++)
        {

Hey guys, I need Help, I'm doing a smaller puzzle game but I have trouble getting the playing field to the center. Playing field is still on the bottom/left I tried to fix it using the forum but nothing happened. Thanks for your help.

Answer 1

As i gather from the picture your gameboard gets drawn inside a Panel ui control. You could set the position of this panel to the centre, so that all its children will be centred alongside it:

MyPanel.transform.position = new Vector3 (Screen.width * 0.5f, Screen.height * 0.5f, 0);
