Bit flags?

[Draco9898]

I was wondering if we could please see an example of a bit flag so we dont have to have so many differrent varibles for our games characters, I.E:

Player.Walking, Player.Ducking, Player.Sitting, when you could just turn it into one varible with different combinations of numbers? I.E: Player.Status

ya know what I mean? Thanks :)

Ahhh Nevermind I think I figured it out, you can assign different 'modes' different powers of 2.

I.E: Ducking= 2, Waving=4, Begging=8


Then if two were on at a time you get different values, I.E:

Ducking + Waving = 6 ;  Ducking+Begging=10

Waving+Begging=12


Then If all three we're on:

Ducking + Waving+Begging=14


So I guess you'd have to make a table and remember what values were each :)

PlayBASIC Code: [Select]

; Create BIT constants.. pre calc 
 Acset = 0
 Constant Bit0 = 2^ac(1)
 Constant Bit1 = 2^ac(1)
 Constant Bit2 = 2^ac(1)
 Constant Bit3 = 2^ac(1)
 Constant Bit4 = 2^ac(1)
 Constant Bit5 = 2^ac(1)
 Constant Bit6 = 2^ac(1)
 Constant Bit7 = 2^ac(1)
  
 print Bit0
 print Bit1
 print Bit2
 print Bit3
 print Bit4
 print Bit5
 print Bit6
 print Bit7
 

 print Bin$(Bit0)
 print Bin$(Bit1)
 print Bin$(Bit2)
 print Bin$(Bit3)
 print Bin$(Bit4)
 print Bin$(Bit5)
 print Bin$(Bit6)
 print Bin$(Bit7)
