[EO] Calling other subs

[peekay]

Now im trying to call over subs into a scripted NPC sequence in attackNPC in EO.
When I try to call getplayerdir(index) it says that its not a defined variable
do I just dim index as long in the attackNPC sub?

thanks

No. "Index" is just a variable name used for the player's number. A quick glance will show you that the AttackNPC sub uses "Attacker".

What about say that ive created a scripted npc behaviour.
And in the script for that npc I call
cannpcmove
can I make the dir set to the players dir
or should i use the updatenpcAI for this

you may need to set it… like Index=GetNPCTarget(NPCNUM, NPCMapNum) or whatever the command is.

Depends on how you want to organize your source I guess. Just try a couple ways to see how it best fits whatever you're making. As for setting the NPC's direction to the same as the player's direction, that's really simple stuff. I'd wager you're trying to make some kind of NPC pet system or improve on the AI. It'll take a lot if you don't know how simple things like that are done.

```
Npc(map, slot).dir = player(index).dir
```
Just fill in map, slot, and index with the appropriate variables as whatever sub you decide to slap that in uses.
