Making a good healer script (finding maximum HP)

Kharlog

Hi,

I'm making a script for any characters capable of casting healing spells. Generally HPLT or HPPercentLT are used to see if there is a need for healing and then some arbitrary number HPPercentLT(object, 50) or HPPercentLT(object, 75) are used to determine which kind of healing spell to use. This is quite dumb approach because every character has very different maximum HP. I would like to know how to get the maximum HP of the character and then calculate how many HPs have been lost (to determine which healing spell is sufficient). How to do this?

You can't really do... math with bgscript. You might be able to make some assumptions based on class, or use CheckStat to figure out a better threshold based on their maxhp.

I...wouldn't say that. You just have to do it "sideways" instead of with a nice neat function like other script languages. Here's the gist of it:

IF
HaveSpell(CLERIC_CURE_LIGHT_WOUNDS) // cures 8HP
HPPercentLT(Myself,76) // at 25% (or more) down from Max
CheckStatGT(Myself,31,MAXHITPOINTS) // I'm at 32 or more HP at maximum, so 25% of 32+ >= 8
//....your other conditions
THEN
RESPONSE #100
Spell(Myself,CLERIC_CURE_LIGHT_WOUNDS)
END

//For 50% or less of maximum
IF
HaveSpell(CLERIC_CURE_LIGHT_WOUNDS) // cures 8HP
HPPercentLT(Myself,51) // at 50% (or more) down from Max
CheckStatGT(Myself,15,MAXHITPOINTS) // I'm at 16 or more HP at maximum, so 50% of 16+ >= 8
//....your other conditions
THEN
RESPONSE #100
Spell(Myself,CLERIC_CURE_LIGHT_WOUNDS)
END

Tried and tested for years, in BP Series scripts. You can apply this for any percentage you like, and if you do the mathwork yourself it will work as intended. You'll not waste a single HP of "curing power" this way. You can alter the conditions to give a little leeway if you wish it (recommended for lower-level PC's/NPC's).

Thanks for informative replies! I guess horredtheplague's method this is better than the "standard" method as BG Scripting language seems to be very limited. I will try it on my scripts.
