I'm new in Lua programming, I am usually working in C++

There is this sentence I need to translate in Lua and I just don't know how to formulate it:

Code: Select allThis is the sentence in C++

 bits[x] |= (1 << cnt)



Could any one be kind and help me in this task?

Try:

Code: Select allbits[x] = bit.bor(bits[x], bit.lshift(1,cnt))
