[Simple SAI question: How to make a SAI trigger by player distance?]

Simple question, hard work to find out.

It is possible to trigger a SmartAI out of combat by a distance? I mean, i looked in-game for examples but them all uses Areatriggers and that's weird since i can't find co-relation between them. I would gladly accept any tip you can give me since im trying to repair Cataclysm quests.

-- Editing: I know that i can solve this with OOC SAI (Out of combat) but i can't set the range in there.

-- Editing 2: What i need is someone talking when in range. So i need to do anything OOC for that reason, the SMART_EVENT_OOC_LOS can't let me set the player as the target, maybe CONDITIONS has something to do with this?

[Make an SmartAI force a player to cast certain Spell]

Hello and thanks for the reading first,

i would love to know if there's a way to make a certain SmartScript force a player to cast certain Spell. I know there's a possibility of put and remove auras and sometimes the same Spell can be used as Aura to force the debuff of the same spell but i would like to know if there's a possibility to do this without need to do an scriptname.

I used this as guide along this years: https://trinitycore.atlassian.net/wiki/spaces/tc/pages/2130108/smart+scripts
I searched a bit for the TrinityCore issue tracker about this and didn't found anything useful about the question itself.

Thanks for reading!
