Hi,
I was wondering on how to save files. I searched this up on the search form, but people just say to save it like a string. I know some about that but just wasn't sure on how to write the code for it. Say I move my character up a few times. Then I hit the save button, let say "S". So I hit "S" and the game saves. I close the game down and go to the load menu of the game. I load back to where my character was just positioned when I saved. Does anyone know what the code would be????
Thanks in advance...

Drew G,

Save:


Let us say that the x,y and z positions of the character are 3,2,5.6. Then, the save file, when opened in a text editor, would look like:


Load:

Lol, ummm, soon I suppose, I will write up a no media file that moves a cube on a matrix and prints the coordinates. I will leave the cube at a section, hit "S" to save, shut the game down and reopen it. I will try your help like that. Thanks though.

Writing as floats has 2 features, one good, one not so good...

1. You can't open the file and read it, it's just garbage. (not so good)

2. If you want to protect your data a little, it's a good starting point.

What do you mean "you can't open the file and read it"? In all my test programs it works great!



It writes, reads... Anything you want.

I think he meant opening them outside DB

I see,

Well, I don't see it as a bad thing... No offence, but why (beside testing the values did write properly), would you want to open them outside the game?

Maybe editing? if you know how you're programming your game very well, you could be able to edit your position to test what happens if there's a wrong value in the save file, or something similar

I guess this can also be done in DB itself...

I think BatVink is referring to the write array commands rather than opening a file and writing the values in a loop.

In the past I too have had problems with the Write command and non-string variables so I switched my saving routines to convert everything to strings before writing, then converting the strings back to numeric variables on loading.

It's not ideal and involves another programming step I know, but after doing that, I never saw the problems I was having ever again.

And as DARKGuy says, if your programs don't load properly, with a text file you can open the data files in Notepad and check what data is in there.
