Is there an @gethit for spells?

I want to do custom damage calculation when a creature is hit.

I also want an if statement to differentiate between a player and an npc, because I don't want to apply increased damage to players.

Basically,

@gethit
damage = <damage> * src.MagicDamageBonusMod

I also want to override magic resist to only be applied in pve. What should I add to remove it from pvp, but in pve override it with my own custom code?

resistMod = <magicresist * mathNumbers>
damage = <damage * resistMod>

@gethit is always fired, no matter the source of damage.

However, Spells instead of firing the @hit trigger will fires the @SpellEffect (in a character events) trigger and the @Effect ( in a spell event), both are called before @Gethit and the order is this:

@SpellEffect -> @Effect -> @Gethit (if the spell cause damage)

Remember that the @Effect must be placed in a spell block (check sphere_spell.scp)

How does @gethit know if it is being hit by a sword, fencing weapon, or spell?

src.action in the @gethit will give you the action used by the attacker (skill_swordsmanship, skill_wrestling, skil_magery and so on...).

Pay attention if the damage is not caused by a "direct damage" spell (example: poison), in this case src.action will return -1

How do I tell with poison?

all damages have at least 2 sub-values: the damage value itself and the damage type value (eg: DAMAGE 15 dam_fire -> cause 15 of fire damage)

most damage spells will include dam_magic flag on the damage value so you can check if damage type have dam_magic on @GetHit. Something like

Code:

ON=@GetHit

IF (<ARGN2> & dam_magic)

  //some code here

ENDIF

but @GetHit is called for every hit you take, and also any items/chars/scripts/etc can also use dam_magic, so there's no guarantee that the code will work only to damages caused by spells. If any other thing cause an damage using dam_magic the code will also consider it an damage caused by spell

so maybe the best solution is change the EFFECT value directly on spells (sphere_spells.scp) or use LOCAL.Effect on @Effect [spells] / @SpellEffect [chars] triggers

I'm having some problems.

I did this to test the local effect and it works:

ON=@Effect
LOCAL.DAMAGETYPE=(<DEF.dam_physical>|<DEF.dam_magic>)
SRC.SAY <eval <LOCAL.EFFECT>>

Inside the @GetHit I can't get the local.effect though.

I've tried a ton of different things:

say <argn2> is effect
say <SRC.LOCAL.EFFECT> is effect (and all the variations I could think of)

I need to get the incoming EFFECT in order to run my custom combat math on it. Any idea how? If I could just see how to make a mob Say how much the Effect was I could handle it from there.

argn1 in @gethit should be the damage you put in local.effect (local variables aren't shared between triggers)

RE: is there an @gethit for spells? - bmanny - 05-22-2017 09:40 AM

I'm getting closer, but there is still odd stuff happening.

say argn1 doesn't return the EFFECT I have set in the spell.

In @Effect on the spell I
say local.effect.

This works and shows me the proper number.

on my @GetHit I have...
say <arng1> which returns odd numbers.

With an effect of 30,30 I'm getting a huge variation. 25-35 almost. How do I simply get the base Effect. How do I stop sphere from running whatever math is running? I want to entirely write my own magery damage system.

I tried putting @SpellEffect on my player to simply Say I casted a spell hoping I could work backwards from there. This did nothing. Am I missing something?

to use EFFECT and LOCAL.Effect values on spells you must make sure that MAGICF_OSIFORMULAS is disabled on sphere.ini, otherwise MAGICF_OSIFORMULAS will replace these values with the result of internal OSI formulas
