I am currently doing a game pack system, it is made up of 2 parts


The first part is PropsControll, it start the game the player's backpack in the SQL to load a list of the first

 

Void the Start () 
{
//initialize 
A Locator. SetProps (this); 
# if UNITY_ANDROID 
IconPath=Application. PersistentDataPath + "/Resources/UI/Icons/Props/"; 
# elif UNITY_IOS 
IconPath=Application. PersistentDataPath + "/Resources/UI/Icons/Props/"; 
# elif UNITY_STANDALONE_WIN 
IconPath=Application. DataPath + "/Resources/UI/Icons/Props/"; 
# the else 
IconPath=Application. DataPath + "/Resources/UI/Icons/Props/"; 
# endif 
SQLiteHelper helper=new SQLiteHelper (); 
Dt_PropsList=helper. ReadTable (" PropsList "); 
Helper. CloseConnection (); 
} 

//list the backpack data 

Public void BagList () 
{
for (int i=0; I & lt; Dt_PropsList. Rows. Count; I++) 
{

Props tempbag=new Props (); 
Tempbag. Name=(string) dt_PropsList. Rows [I] (" Name "), 
Tempbag. Amount=(int) dt_PropsList. Rows [I] (" the Amount "); 
Tempbag. The Description=(string) dt_PropsList. Rows [I] (" Description "); 
Tempbag. Icon=IconPath + (string) dt_PropsList. Rows [I] [] "Icon" + ". PNG "; 
_props. Add (tempbag); 

} 
} 

The second part is tied to the backpack button code, its job is to read PropsControll List, and added into the dictionary

 


Public PropsMaterial _temp; 
Public Image _tempIcon; 
Public Text _tempDescription; 
Public Dictionary _iconDic=new Dictionary (a); 
Public List _material; 
Public PropsControll _controll; 
Public RectTransform _panel; 
Public UIManager _ui; 
Public ResearchMusic _research; 



Private void Awake () 
{
_controll=FindObjectOfType (a); 
_controll. ResearchList (); 
_ui=FindObjectOfType (a); 
for (int i=0; I & lt; _controll. _props. Count; I++) 
{
Sprite temp=FileReadWriteHelper. LoadSprite (_controll _props [I] Icon, 100) 30; 
_iconDic. Add (_controll _props [I]. Name, temp); 

} 

The present question is that, when I first enter the scene, backpack work
But if I switch out of the scene, the problem will appear, and backpack could not show any data
How do I solve?

CodePudding user response:

1, repeat adding problems
Here recommend to join if a judgment has been added the corresponding data, if it is, then give up to add,
Ps: data can be added in the last backpack when joining a signal value as judgment,

2: suggest not actually in the form of official teaching around mount component programming, suggest set up with standard entity class engineering structure, bags would not be affected by the scene,
