SetUnitLifePercentBJ to Natives or a Formula?

[Titanhex]

So using the SetUnitLifePercentBJ is really simple to use, but it's a BJ and it likely causes leaks from the natives I've been looking at.

    call SetUnitLifePercentBJ( GetTriggerUnit(), ( GetUnitLifePercent(GetSpellTargetUnit()) - 1 ) )

However, just to set it to natives seems like a huge chore. I'm looking at the coding and my head hurts. First I need to turn it into a native, which requires turning RMaxBJ into a native, which requires an if, though since it uses reals it shouldn't leak and I might just be able to use it leak free.

Then I have to turn GetUnitLifePercent into a native because it's part of the percent I need to input for RJMaxBJ, which means turning GetUnitStatePercent into a native, which requires the use of some locals and ifs and whatnot, which is a lot of thinking and rearranging.

There's gotta be an easier way! I'm not a math buff, so maybe someone could tell me how you would decrease an enemies life by a percentage. Like -1%.

I got this far in before realizing how convoluted it would make my coding to do all this, and I knew I wasn't the only one who needed an easier way.

SetUnitState(target, UNIT_STATE_LIFE, GetUnitState(target, UNIT_STATE_MAX_LIFE) * RMaxBJ(0,) * 0.01)

It's a rule of three:

MaxLife = 100%
Life = x%

If you want to calculate how much is x% of the unit's max life:
Life = MaxLife*x/100

But the life-setting native can only SET. So if you want to remove life you'll have to do like this:

call SetUnitState( <unit>, UNIT_STATE_LIFE, GetUnitState(<unit>, UNIT_STATE_LIFE) - <amount> )

Use the widget natives for removing life and getting max life, they are far faster.

Percentage life in multiplyer form (percentages are stupid as multiplyers are all you can use in the end) is...
currentlife/maxlife

Hardly rocket science.

Ahh, I see. I was merely over-complicating the problem.

Simply to take away 1% of a units max life, I do maxlife x 0.01 and set it's life to current life - the product of maxlife x 0.01.

It all makes sense. I shouldn't attempt some of this stuff with lack of sleep :\
