clear/empty an array - redex - 2021-07-31

hi!

i wanted to know is there anyway to clear an array with only a few lines? i have player info in this array:

Code:
enum e_playerinfo

{

? ? someInt,

? ? Float:someFloat,

??? someString[144],

}

new playerInfo[MAX_PLAYERS][e_playerinfo];

and i wanted to know how can i clear it in on player disconnect after saving the values in sql, i used to do like this:

Code:
public OnPlayerDisconnect(...)

{

? ? playerInfo[playerid][...] = 0;

? ? playerInfo[playerid][...] = 0.0;

? ? playerInfo[playerid][...] = "";

? ? ...

}

and i had to do this for every variable i add, is there anyway to make this more simple?

I think that this should work:

Code:
for(new i; e_playerinfo:i < e_playerinfo; i) { playerInfo[playerid][e_playerinfo:i] = -1; }

so it will work for any data type?
i want it to make the strings "", and ints 0, i think this is not working for every datatype

me neither, but what you can do is manually reset strings, you shouldn't have that much of them anyways?

This is also a very good way to reset that enum https://github.com/pBlueG/SA-MP-MySQL/blob/master/example_scripts/login_system-cache.pwn#L106
