for those who don't really understand what's going on is the HP bar in the bottom prints what percentage of HP is remaining through a set of 20 sprites with names that have a range from 0-100 with increments of 5 and it takes the HPPercentage variable which is found out by calculating the percentage of how much hp is full compared to the max

which is simply done with the tride and true Part/Whole x 100, and then rounding it, but since Scratch rounds with decimals only using the Modulo function set to 5 it'll find out what exact number is needed to reach the closest variable of 5 and then the script adds that modulo number to the percentage to round it to a variable of 5 to be used in displaying the proper HP gauge filling with the sprite using the join block with Join hp + "HPPercentage"
