Hi,
I built a game this game works just fine in unity editor but when I built it I got some errors with the OnGUI function while displaying a message it suddenly disappears what could be the problem is there a way to fix this?
Plus could I have some coding problems even if no bugs or errors are detected by unity?
Please I really need some help!!
thank you!!
Well theres no real info here to help you with ,post some of the problematic code. And yes, you can have bugs that the editor does not know about. Usually , if the editor knows about it , its not a bug , its an error.
Thank you for the reply but I forgot to mention that when I press the alt tab button and refcus on the game window the messages reappears so I don’t think that it’s a code error. right?
It sounds as if you dont have the application set to run in background, you can check this in the Player Build Settings.
what willc said.
yeah I did check it
If this can help I also have a login page and when I run the game for the first time the login button works just fine but when I quit the game and reaccess it and press the login button it doesn’t do anything why?
I have a SQLite database attached to my game is this a good code?:
function GetConclusion(idm, score){
var query : String;
var string1:String;
connection = "URI=file:Assets/PJI Game.s3db";
dbcon = new SqliteConnection(connection);
dbcon.Open();
query = "SELECT Phrase FROM Conclusion where ID_Mission="+idm+" and Score="+score;
dbcmd = dbcon.CreateCommand();
dbcmd.CommandText = query;
reader = dbcmd.ExecuteReader();
string1=reader[0].ToString();
dbcon.Close();
return string1;
}
You do realize there is a log file in your standalone directory where error messages go that would normally go in the Debug if you were in the Editor right? That would at least give you a a message to get started…
yes I know 
but I am asking because this code works just fine in the editor but i am having troubles in the built game so I am rechecking my codes.but thank you for your reply.
I’m having a similar problem. For some reason, the standalone build fails to find some GameObjects 
I don’t know why the links don’t work, as everything runs smoothly in Unity’s editor
what is your problem can you tell me in details perhaps I can help you with it cz mine was that the built game was not able to read the database or to access it this was because of the dlls I needed newer versions of SQLite.dll and SQLite3.dll but you’re telling me that your game is not reeding some game objects how is that?
hello all.
i am new in unity.
i want to create a game in which i need to create local database.
i read many a posts on unity/google but i cant find anything very clear and fast…
so any one can tell me the clear steps for creating a local database in unity-game for iphone/ipad…???
here is the code that i used but it only creates the database file while i run it on MAC…
//==============
/— this code i am using to create database------/
import System.Data; // we import our data class

{
connection = “URI=file:” + p; // we set the connection to our database
dbcon = new SqliteConnection(connection);
dbcon.Open();
}
function BasicQuery(q : String, r : boolean) // run a basic Sqlite query
{
dbcmd = dbcon.CreateCommand(); // create empty command
dbcmd.CommandText = q; // fill the command
reader = dbcmd.ExecuteReader(); // execute command which returns a reader
if(r) // if we want to return the reader
{
return reader; // return the reader
}
}
// This returns a 2 dimensional ArrayList with all the
// data from the table requested
function ReadFullTable(tableName : String)

{

for (var i : int = 0; i < reader.FieldCount; i++)
lineArray.Add(reader.GetValue(i)); // This reads the entries in a row
readArray.Add(lineArray); // This makes an array of all the rows
}
return readArray; // return matches
}
// This function deletes all the data in the given table. Forever. WATCH OUT! Use sparingly, if at all
function DeleteTableContents(tableName : String)
{
var query : String;
query = "DELETE FROM " + tableName;
dbcmd = dbcon.CreateCommand();

reader = dbcmd.ExecuteReader();
}
// This function reads a single column
// wCol is the WHERE column, wPar is the operator you want to use to compare with,
// and wValue is the value you want to compare against.
// Ex. - SingleSelectWhere(“puppies”, “breed”, “earType”, “=”, “floppy”)
// returns an array of matches from the command: SELECT breed FROM puppies WHERE earType = floppy;
function SingleSelectWhere(tableName : String, itemToSelect : String, wCol : String, wPar : String, wValue : String) // Selects a single Item
{

var readArray = new Array();
while(reader.Read())
{
readArray.Push(reader.GetString(0)); // Fill array with all matches
}

}
function CloseDB()
{
reader.Close(); // clean everything up
reader = null;

when i am running his code on MAC it works fine.
but on i-phone/simulator it cant read the database file and application get crash…
Thanks
dude use code tags…
