Problem with setting a bit

1

Something is wrong with this function.


        public static function setBit(bitData:int, Bit:int, setTo:Boolean):int {
            var newBitData = bitData | (int(setTo) << Bit);
            return newBitData;
        }

var bitInt:int = 5;
            trace(bitInt);
           bitInt=bitFunctions.setBit(bitInt,0,false);//Or true
            trace(bitInt);

Running a trace on both sides for the number 5 shows no change… True or false.

This function seems to work properly in this code here…


var bitInt:int=0;
                    if (tileType == 1 || tileType == 2) {
                        //Set bit 0 to true for walkable
                        bitInt=bitFunctions.setBit(bitInt,0,true);

                        if (tileType == 1) {
                            //Set bit 2 to true for buildable
                            bitInt=bitFunctions.setBit(bitInt,2,true);
                        }
                    }

                    pathMapVec[Row][Col]=bitInt;

The first function only seems to work when the bit isn’t set to begin with…
