Need help with a variable

[NeveZz]

So I have a variable (global.coins) and I want it to be the same value as before i restarted the game. I have a initialization room that sets the global.coins value to 0. How to fix this?

A quick and easy method would be to use an INI file to save value at game end and load at game start.

How do I do that? Is there any tutorial online?

Press F1 and search for INI, it shows some example usage.

Take a look at the manual pages about File Handling.

I've never been more confused in my life...

///When I initialize the game

 ini_open( 'savedata.ini' );
 global.coins = ini_read_real( 'save1', Coins, 0 );
 ini_close();

///When bullet hits enemy i save game...

 ini_open( 'savedata.ini' );
 global.coins = ini_read_real( 'save1', Coins, 0 );
 ini_close();

Giving this:

ok managed to get the game running, but the coins are not saving.

///Receive Coins

  global.coins += 10;
  ini_open("savedata.ini");
  ini_write_real("save1", "Coins", global.coins);
  ini_close();

///When Game is Opened

globalvar coins;
 ini_open('savedata.ini');
 global.coins = ini_read_real('save1','Coins',0);
 ini_close();

Are you sure the save code is running? Is global.coins being overwritten AFTER it loads from the .ini?
Try putting a "show_message("ini loaded, global.coims: " + string(global.coins)); with the load code
