Yes, with IanMs Matrix 1 Utilities Plugin you can save a User Defined Type with just using his SAVE ARRAY TO DATAFILE command and load that same information with LOAD ARRAY FROM DATAFILE. All you do is define the UDT like you normally would, fill the array, and save it.

If you don't already have IanMs Matrix 1 Utilities Plugin where the heck have you been?!

Here's the link: http://forum.thegamecreators.com/?m=forum_view&t=96084&b=7

On another note; all of this code is totally superfluous:


A spade is a spade, telling it what it is doesn't change a thing.

Lol I don't have them but have used them in the past. They are good, as are a few plug ins out there, but I avoid using plug ins of late to save upgrade issues. Of course if I had a project that needed it I would use it then

I use a lot of IanMs commands for most of my projects.

I really love the file commands and some classics like MID$ that bring back the original Basic version of MID$. I was shocked when I found out Darkbasic would only extract one character with MID$. I ended up making a function to make my own MID$ command (as we all did probably) till IanM brought out his version.

yes it does if I want the states to change as i load back in. spade can =1 but when i load back in it will always =0 if I do not tell it what it =s.

Er you seem to have missed the point Daniel...the code Scraggle has pointed out is useless - you might as well have wrote 0=0 over and over. If you wrote game1percent=0, coloff1=1 etc then it would be of some use as you would be using those values as default values by resetting them for each variable when you "load back in"(assuming you mean you use a label and goto command). As it stands variables default values are always 0 - if they were declared as local variables within a specific nested loop and then you use the goto command to jump outside that nested loop the variables are no longer usable for the values they had as they remain tied locally to that nest; they can be used again but will initially hold a default value again(0)

@James H

I beleve you miss my point my friend, when I take out that part and i save my games all the stats are 0, so when i do something to change a state to 1 like open a locker in game, then openlocker=1
then if i save it it will save that open locker=1, then when i load it in it will always=0 unless I tell it to = what was loaded in. see what is in memory is not changed unless i call it to be changed from what was saved.How do I know this? Like i said I took out that part in the load and all my states =0 and nothing was saved. unless im doing it wrong and if this is so please tell me a better way and I will try it out.thanks

Did you declare all your variables prior to entering the main code block where you load/save? DBP has automatic variable declaration which could cause problems if you don't declare them first.

The fastest code is the code never written.

@ Daniel

Just jumping in on your arguments, your code basically does the following:

you set a variable:

a=2

you write that variable to a file:

open to write 1,"yeah.bla"
write word 1,a
close file 1

Then, later on you read in that variable from the file into the variable "a"

open to read 1,"yeah.bla"
read word 1,a
close file 1

And then you tell the variable "a" that it is equal "a"?

a=a

Why?

No. Like this:
global OpenLocker as byte
OpenLocker=0 `the initial state
global DoStuff as integer
DoStuff=0 `the initial state
global Amisostuppidthatididnotgetitthefirsttime as DWORD
Amisostuppidthatididnotgetitthefirsttime=1 `a true statement LOL...

Most variables in your game should be declared as 'global' BEFORE they are used in your program. Make a function that does like this:
function SetGlobals()
global var1 as float
global var2 as integer
......
endfunction

Then call that function at the beginning of your program. Remember, don't do any 3D objects here unless you are doing it after changing your display mode-- simple variables are fine to do before display mode, just not 3D objects.

ok, i see it now, setting them all to global will fix it, well i do know all of them are integers with number values, all my floats are just postitions of my camera and objects. so it should be easy.

Because I haven't seen all of your code, I can't guarantee it will work, but it's a start. It's good practice to declare your variables before use....

Let me know if it works or not.

I have had problems with declaring variables like this:
global MyVar1 as integer =1
Keep in mind that all variable declarations with 'as' initialize as '0' (or so I've seen). If you want to be sure that the variable has any value other than '0', you should do this:
global MyVar1 as integer
MyVar1=1

I may have been smokin something when I had that problem, but the latter is the way I do them exclusively.

'fogvalue' should be one of your globals. Your last line might be better written as:

You could also make this a little smaller like:


I think this is what you were asking me....
