AlliedModders - [INFO] Bitsums and Operators

Great tutorial! but i have somes doubts

PHP Code:


		
			
if (bistum_is_alive & (1<<id)) // if this is checking if is user alive, how can i check is isnt alive? using this same method
{
}

and how can i make it more "manipulable", like

PHP Code:


		
			
 MyVar |= (1<<id) // Setting to true 
         Myvar &=  ~(1<<id)  // Setting to false

PHP Code:


		
			
stock SetVarStatus( bool:Status, Var, id )
{
    switch(Status)
    {
        case true:
        {
               Var |= (1<<id)
        }
        case false:
        {
               Var &=  ~(1<<id)
        }
     }
}

something like this but better?

Solved:

PHP Code:


		
			
#include <amxmodx>
 
#define SetPlayerBit(%1,%2)      (%1 |= (1<<(%2&31)))
#define ClearPlayerBit(%1,%2)    (%1 &= ~(1 <<(%2&31)))
#define CheckPlayerBit(%1,%2)    (%1 & (1<<(%2&31)))

new BitSumTest;

public plugin_init () 
{ 
    register_plugin( "Test", "1.0", "XSlayer" );
    register_clcmd( "bit", "bitsum" );
} 
public bitsum( Client )
{
       if(!CheckPlayerBit( BitSumTest, Client )) // if is false
       {
             SetPlayerBit(BitSumTest, Client);
             client_print( Client, print_chat, "BitSum Status: %d", CheckPlayerBit( BitSumTest, Client )); // setting to true
       } 
       else // if is true
       {
             ClearPlayerBit(BitSumTest, Client);
             client_print( Client, print_chat, "BitSum Status: %d", CheckPlayerBit( BitSumTest, Client )); // setting to false
       }
       return 1;
}
