Global Variables Maximum? Tipps?

[Yuka]

Hello,

 

I plan on writing my own achievements script, thus I think I should be careful with the player variables.

Is there a maximum for variables a character can hold?

 

And are there some tipps how I can save variables? I probably can sum some up with bitshifts, right?

src/common/mmo.h

#define GLOBAL_REG_NUM 256 ///Max permanent character variables per char
#define ACCOUNT_REG_NUM 64 ///Max permanent local account variables per account
#define ACCOUNT_REG2_NUM 16 ///Max permanent global account variables per account
#define MAX_REG_NUM 256 ///Should hold the max of GLOBAL/ACCOUNT/ACCOUNT2 (needed for some arrays that hold all three)

#define GLOBAL_REG_NUM 256 ///Max permanent character variables per char
#define ACCOUNT_REG_NUM 64 ///Max permanent local account variables per account
#define ACCOUNT_REG2_NUM 16 ///Max permanent global account variables per account
#define MAX_REG_NUM 256 ///Should hold the max of GLOBAL/ACCOUNT/ACCOUNT2 (needed for some arrays that hold all three)

How high can I increase those without danger?

I'm not sure, but I think anything below 256..

In short, if you need a lot of variables, it's far safer to create a new SQL table for the data instead.

Sum up bitshift is easy, but then do you have a plan in mind on how to parse them back to their original value?

Well, I have a string like "ooooooooooooooooo" where each position stands for an achievement, when the player achieved that one it will replaced with a "x".

And I have a number like "00 00 00 00" indicating how many rewards of kind 1, 2, 3 and 4 the user got. To get the last two digits I do x%100, for the second two last I do (x%10000)/100 and so on.
