for loop

How does a for loop similar to this work ?

for (pos = 0; pos < maxPos; pos++,
(hFPos += HVEL), (hFtmpPos += HVEL), (velPos += DIM)) {...}

I undertsand the first bit where I initilise a value pos and then increment it until maxPos, but what are the other things ? Thanks in advance !

They are just other variables being incremented by what I would assume are #defines (because they are capticalised and that is the convention).

This if statement is making use of the comma (,) operator

The comma operator, written as a comma (,) takes two operands. It evaluates its left operand and discards the value. It then evaluates its right operand, and returns that value as the result of the expression.

This is basically a comma used anywhere as part of an expression except in a function call (or declaration or definition).
