NPC Code:

if (wasshot) {
for (i=0; i<npcscount; i++)
callnpc i,swimming;
}

basically it calls every npc on that level if the npc was shot and gives it a swimming thing

and inside the other npcs you can say

if(swimming){
//coding
}

so humm lets say the npc calling that code is a person npc

and it gets shot

then the person npc would call all the npcs and set
swimming

then in the other npcs that you want it to effect you say

if(swimming){

}

and do whatever you want in that coding once the person npc gets shot

NPC Code:



if (wasshot) {           Makes the following stuff executed when the NPC is hit by an arrow

  for                    Initializes a for-loop

    (i=0;                Sets the variable "i" to 0 once

     i<npcscount;        Defines when to repeat the script after the ) thing: When the variable i is lower than the amount of NPCs in the level

     i++)                Increasing i each time the script after ) is run

    callnpc i,swimming;  Setting the flag "swimming" to true for the NPC with the index "i"

}

So what it would be doing in "normal" talk:
1) Wait until the NPC is hit by an arrow.
2) Set "i" to 0
3) Tell the NPC with index "i" that "swimming" is called (makes if (swimming) happen)
4) Increase "i" by one
5) Go back to 3 if "i" is lower than the amount of NPCs in the level
6) Stop executing
