bool MAX_PLAYERS[MAXPLAYERS + 1];

Hi all, how to make that the place 66 was for example 4.

I don't really know what you're asking besides "how do I make an array of 4 booleans." If that's what you're asking, bool myArray[4];.

bool MAX_PLAYERS[MAXPLAYERS + 1];

It has no sense. MAX_PLAYERS is reserved name of const.
UPD. I didn't notice that MAX_PLAYERS and MAXPLAYERS is different. Not a good idea to give such alike names.

Also, no sense.

bool can be true or false, not 4. If you don't plan to cast of course. In such case:

bool arr[MAXPLAYERS + 1];
arr[65] = view_as<bool>(4);

I resolved the issue.
