Somebody correct me if I'm wrong but I'm 99% sure this is how it goes:
If IsWalking = 1 (since if a/d is pressed it registers as one in math), it switches the costume to the corresponding item. The floor of a number is the greatest possible whole number less than or equal to the number you're calculating; hence the floor of 6.5 would be 6. Since frame goes up by 0.1, this adds a pause to the animation frames so you can see the anims clearly: the floor of frame would be zero until it reaches 1. () mod () gives you the remainder of the first number divided by the second; i.e., 13 mod 6 = 1. If the dividend is less than the divisor, the number you get is automatically the dividend. Looking at the code as is, frame would equal zero, so floor of frame(0) mod length of walking(3) would equal 0. 0 + 1 is 1, so it would set the costume to costume 1. When floor of frame goes up to 1, (1 mod 3) + 1 equals 2. (2 mod 3) + 1 is three, and (3 mod 3) + 1 is 1. The cycle repeats with 4,5,6 and so on. And lastly, if IsWalking doesn't equal 1, then the standing costume/animation plays.
