Welcome to The Bug Genie

My goal: being able to detect when an entity gets hit by a lightningbolt.  ⇑ top

When an entity gets hit by either a weapon or a spell it triggers the ON HIT event. The event has 2 parameters: PARAM1 = some floating point number (probably damage or distance) PARAM2 = source of damage

When it is a magic spell that hits the entity then PARAM2 is "spell", but there is no way of knowing what spell is causing it.

There is another event, which gives more info: ON SPELLCAST, where PARAM1 contains the name of the spell as a string. However the event only gets called once at the start of the spell. If a spell lasts for longer and the player moves around hitting entities then it will not get information on it.

I found these events on this wiki page: https://wiki.arx-libertatis.org/Script:Events

My solution is to keep track of the player's last spell in a variable that have been cast and whether it was lightningbolt or not. Then if the entity gets hit and PARAM2 is "spell" and my tracking variable is set, then I'm good to go. I'm also checking if the SENDER in the spellcast event is the player.

Limitations:

1. will not detect if the player is casting multiple spells at once (having life drain and lightningbolt being triggered the same time). If I would to detect both of these events, then I would have to keep 2 tracking variables for the 2 spells, 3 variables for 3 spells, etc.
2. would also require extra coding and variables for all enemy creatures (liches, snake women), who can also fight the player using lightningbolts and accidentally hit the target entity, which is because of my workaround implementation.

My workaround:

ON INIT {
  SET §lightningWasCast 0
  ACCEPT
}
 
ON SPELLCAST {
  IF (^SENDER != PLAYER) ACCEPT
 
  IF (^$PARAM1 == lightning_strike) {
    SET §lightningWasCast 1
  } ELSE {
    SET §lightningWasCast 0
  }
 
  ACCEPT
}
 
ON HIT {
  IF (^$PARAM2 == "spell") {
    IF (§lightningWasCast == 1) {
        HEROSAY "buzz!"
    }
  }
  ACCEPT
}

My ideal implementation:

ON HIT {
  IF (^$PARAM2 == "spell") {
    IF (^$PARAM3 == "lightning_bolt") {
        HEROSAY "buzz!"
    }
  }
  ACCEPT
}
