HP and MAXHP Problem

[Ausomeman]

Alright, I am trying to do something really simple, and it isn't working. :P

Basically, I have a horizontal counter with a minimum value of 0, and a maximum of 100.

I then have 2 Global Values of HP, and MAXHP. I set it up so that the counter will always be set to HP/MAXHP*100.

This should return the percentage of HP they have left and allow me to change the maxhp as they progress through the game.

The issue is, when I set HP to ANYTHING other than MAXHP, the counter will set itself to 0. Any ideas why?

I also tried,

(HP/MAXHP)*100 = Countervalue

I get the same result.

max HP times 100 will always be a massive number! HP divided by that massive number is going to be super close to zero (rounded down to zero if you're not using fractions)

maybe you mean

(HP/MAXHP)*100

Because you're dealing with integers, doing the division first will round the result to 0 (which, when multiplied by 100, will still be 0!) You should be able to see the right result if you do it the other way round, using (HP*100)/MAXHP.

Thanks a ton David. That solves it. I was not aware that MMF2 could not handle decimals.

[DavidN]

Well, it can - though you have to indicate to it (as in other languages) that you want to use them, by multiplying a value by 1.0 before using it, if it doesn't have a decimal fraction already.

That is not the case. MMF can deal with decimals fine, as long as you define them as decimals.

That is,

100 / 3 = 33
but,
100 / 3.0 = 33.3333

if you use all integers, then your answer will return an integer. But once you define a value as a decimal value, it will continue to use decimal fractions.

To turn a decimal number back into an Integer, use the int() operator:
int(100 / 3.0) = 33
