My current coding challenge.

Question

I have a function I need to spit out a number between 16 and 10,000. Context: HP damage.

Given that it accepts inputs x, y, z.
x will never be below 1 or above 99.
y will be between 15 and 255.
z same rules as y.

ie.

(levelX + 2*atkY) - defZ = 16;
// Here's the low end

Getting from there to the high end is the problem. With this formula, 594 is the top. Which I could use, but I would have to scale my ideas down.

(99 + 510) - 15

Any bright ideas?

Answer 1

Oh I made a mistake, sorry ! You have to do : /(MaxOfCurrentRange - MinOfCurrentRange) instead of /MaxOfCurrentRange

Answer 2

I'm a game programmer. I see that you have a function to calculate damage output, but I don't quite understand your issue. Are the numbers outside of the range that you were anticipating?

Answer 3

Thanks for the response. Seems legit if I plug in proper top end values. Hmm.

Answer 4

ok, not my piece of cake, good luck

Answer 5

If I'm understanding.

Top end result, for example.

(594 - 16)/594 * (10000-16) + 16
= (578 / 594 * 9984) + 16
= 9731.07 repeating...

did I do something wrong? Seemed so legit at first

Plug in low end.
(0 * 9984) + 16 = 16, that works.

Answer 6

i would just do hitValue%maxHit if it is 20x greater than your ideal range.

Answer 7

@tom, your suggestion imply behaviors not wanted in a game. If the player has an attack and a level which makes the operation go to a multiple of maxHit+1, it will do 0 damage, but with just one level less, it will do maximum of damage

You should do :
(result - MinOfActualRange)/MaxOfActualRange*(MaxRangeWanted - MinRangeWanted) + MinRangeWanted

With this formula, the result will be a projection of the old range in the new (like converting the reduction of a price from % to actual money)

Answer 8

unclear definition of the problem, as far as I am concerned. is this related to some HP hardware? some detailed illustration would help

Answer 9

Working on a roleplaying game. HP as in Health Points. I can be more specific if u need.

Answer 10

@Tom, can u elaborate a bit?

Answer 11

hitValue = (levelX +2*atkY)-defZ;
hitvalue%(maxHit+1);//would always result in a value less than or equal to maxHit

Answer 12

Yeah, thats the problem @Keto, looking for help making my formula output the right range
