Include Bit Functions

[#Gromov]

Include содержит функции для манипулирования битами.​

stock GetValueBit(value,bit){ 
    return (value >>> bit & 0x01);

Пример:

new PlayerConfig[MAX_PLAYERS][32]; 

stock ExtractPlayerConfig(playerid,value){ 
    for(new i=31; i >= 0; i--){ 
        PlayerConfig[playerid][i] = GetValueBit(value,i); 
    } 
} 

stock PackPlayerConfig(playerid,&value){ 
    for(new i=31; i >= 0; i--){ 
        SetValueBit(value,i,PlayerConfig[playerid][i]); 
    } 
}
