Hello,
I'm trying to fingure out how to do bitwise operations in Max. All I want to do is be able to set or clear bits based on a bitmask.. For example, in other languages, & and || always did this fine. For some reason it isn't porting over to max well for me. Here is a simple test i whipped up. I have a value of 3 being held in a variable called flag (bits 1 and 2 set). I am trying to use & and | to toggle bit 1 on/off... Which should result in the flag variable toggling between 2 and 3.. DOesn't seem to be working...
I understand I can use XOR for this, but i don't simply want to toggle the bits, I want to set them if not set, and/or clear them if not cleared.. Here is my sample code. Am I doing something wrong, or is this Max related??
