SIKI学习——贪吃蛇案例07
作者：互联网
01-对于用户设置的储存
补充：在main场景中给Home绑定方法。
在Start中将Go更名为Start
在start中新建空物体ScriptsHolder，并挂载StartUIController脚本，
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class StartUIController : MonoBehaviour
{
public Text lastText;
public Text bestText;
public Toggle blue;
public Toggle yellow;
public Toggle border;
public Toggle noBorder;
void Awake()
{
lastText.text = "上次：长度" + PlayerPrefs.GetInt("lastl", 0) + "，分数" + PlayerPrefs.GetInt("lasts", 0);
bestText.text = "最好：长度" + PlayerPrefs.GetInt("bestl", 0) + "，分数" + PlayerPrefs.GetInt("bests", 0);
}
void Start()
{
if (PlayerPrefs.GetString("sh", "sh01") == "sh01")
{
blue.isOn = true;
PlayerPrefs.SetString("sh", "sh01");
PlayerPrefs.SetString("sb01", "sb0101");
PlayerPrefs.SetString("sb02", "sb0102");
}
else
{
yellow.isOn = true;
PlayerPrefs.SetString("sh", "sh02");
PlayerPrefs.SetString("sb01", "sb0201");
PlayerPrefs.SetString("sb02", "sb0202");
}
if (PlayerPrefs.GetInt("border", 1) == 1)
{
border.isOn = true;
PlayerPrefs.SetInt("border", 1);
}
else
{
noBorder.isOn = true;
PlayerPrefs.SetInt("border", 0);
}
}
public void BlueSelected(bool isOn)
{
if (isOn)
{
PlayerPrefs.SetString("sh", "sh01");
PlayerPrefs.SetString("sb01", "sb0101");
PlayerPrefs.SetString("sb02", "sb0102");
}
}
public void YellowSelected(bool isOn)
{
if (isOn)
{
PlayerPrefs.SetString("sh", "sh02");
PlayerPrefs.SetString("sb01", "sb0201");
PlayerPrefs.SetString("sb02", "sb0202");
}
}
public void BorderSelected(bool isOn)
{
if (isOn)
{
PlayerPrefs.SetInt("border",1);
}
}
public void NoBorderSelected(bool isOn)
{
if (isOn)
{
PlayerPrefs.SetInt("border", 0);
}
}
public void StartGame()
{
UnityEngine.SceneManagement.SceneManager.LoadScene(1);
}
}
02-完成换肤与其他配置读取
新建Resources文件夹，将原本的蛇的图片放置在Resources文件夹下。
将图片置空
