Created page with "Uses Firestorm Preprocessor for the defined constants but you can just rewrite them as integer DAMAGE_TYPE_* = #; each. Code might get moved to GitHub later for easier versio..."

New page

Uses Firestorm Preprocessor for the defined constants but you can just rewrite them as integer DAMAGE_TYPE_* = #; each.

Code might get moved to GitHub later for easier version management, README and multiple script variants.

This is where we first receive damage reports and have the opportunity
to adjust any damage for weaknesses and resistances.

Best practice is to use simple, understandable multipliers.

But you can also make multipliers location dependant to create weakspots
instead of being applied generally. This would make things more fun.

I've implemented Combat Log Writing in the form of simple description reports
via the linkset data system. Using LSD I can avoid spamming the log and also
target the logs via llRegionSayTo - This would be used in combination with a PvP HUD

You could trigger any visual and auditory effects here based on type & amount
For example what I did on my walking spider mech:

// Constants defined at top of script:
#define FX_MINIMUM_AMOUNT 10.0
#define FX_THRESHOLD_DURATION 1.5

// Code in this while loop:
// Limit how many times we trigger a special effect based on minimum damage and duration

timeLastHit = llGetTime();

|| type == DAMAGE_TYPE_EXPLOSIVE) llTriggerSound(SOUND_EXPLOSIVE_HIT, 0.3);
else if(type == DAMAGE_TYPE_PIERCING) llTriggerSound(SOUND_BULLET_HIT, 0.4);
else if(type == DAMAGE_TYPE_ANTI_TANK) llTriggerSound(SOUND_HARD_HIT, 1.0);
}

You could do fun things like tweaking sound volume and particle size/amount
based on the amount of damage and type inflicted.
Such as an electric buzz on electric or metallic sparks on piercing.
Checking with llGetTime() you can avoid spamming the effects too frequently.

If you want to keep things easy to manage you can use llMessageLinked
to have another script manage the visual and auditory effects for you.

Just make sure to check with llGetTime() like I did above before firing
off those linked message :P as there may be a LOT of damage events
being processed here.
