please use [ code ] and [/ code ] :)
wildgoose 420 Practically a Posting Shark
This posting is similar to one posted a day or two ago related to a 4x4 Bingo. My recommendations are the same to you!
You are doing a 3x3, so use a bit array!
0 1 2 0x001 0x002 0x004
3 4 5 so 0x008 0x010 0x020
6 7 8 0x040 0x080 0x100When a slot is chosen set a bit
MyPick = 3
b |= 1 << MyPick
So b = 0x008 ; 000001000
Then to do your pattern match...
Second Row pattern
000
XXX = 0x38
000So to match your pattern
if ( (b & 0x38) == 0x38) pattern found
You can insert the pattern codes { 0x38, etc. }
into a table lookup to save space!
This should drastically reduce the size of your code!
