Bits
'bits' returns a bit-field indicating which buttons the player is pressing. A particular button press can be checked by using ifvarand with the values listed at the end of this article.
This technique does not work properly with the weapon selection keys, however. They share four bits in the second-to-lowest byte, which represent the number of the corresponding weapon. They can be decoded as follows:
getinput[THISACTOR].bits temp
shiftvarr temp 8
andvar temp 0xF
switch temp
case 1:
//"1" pressed
break
case 2:
//"2" pressed
break
//etc.
case 10:
//"0" pressed
break
case 11:
//previous weapon
break
case 12:
//next weapon
break
endswitch
