Lightning damage

#1 Do a radius search from the point of impact, do damage to anyone within range?

#2 How do I know a lightning event took place? I looked at the c code and dont see a notification like Lightning::onStrike()

#3 I'd suggest adding the notification, if there isn't a callback happening. Just look at the lightning strike event and see what's up...

#4 You mean the lightning strike event as in the engine code?

I thought I saw one of these threads that had it in script.

How do I find point of impact in script?

#5 This works for me:

Add the two lines under:
datablock LightningData(DefaultStorm){
directDamageType = $DamageType::Lightning; // added
directDamage = 100; // added, player default life is 100

Then add this function below the datablock:
function LightningData::applyDamage(%data, %lightningObj, %targetObject, %position, %normal){
%targetObject.damage(%lightningObj, %position, %data.directDamage, %data.directDamageType);
}

#6 Sabrecyd, thanks, that works for me too.

Just when I thought I was starting to understand the scripting this routine tosses me back into the dark ages...sigh

I looked at the applyDamage() function in the lightning.cc source and saw that it was called internally. I can't make the mental connection with how this one gets called in script and can't see how the parameters get loaded.

#7 It's a struggle I know. The part in the lightning.cc code that works with the script is this function:

void Lightning::applyDamage( const Point3F& hitPosition,
                             const Point3F& hitNormal,
                             SceneObject*   hitObject)
{
   if (!isClientObject() && hitObject != NULL)
   {
      char *posArg = Con::getArgBuffer(64);
      char *normalArg = Con::getArgBuffer(64);

      dSprintf(posArg, 64, "%f %f %f", hitPosition.x, hitPosition.y, hitPosition.z);
      dSprintf(normalArg, 64, "%f %f %f", hitNormal.x, hitNormal.y, hitNormal.z);

      Con::executef(mDataBlock, 5, "applyDamage",
         Con::getIntArg(getId()),
         Con::getIntArg(hitObject->getId()),
         posArg,
         normalArg);
   }
}

Looking for the "Con::executef" line is how I find some script related stuff that might be available but not shown in the demo scripting.

Hope that helps a little.
