Help wanted from a beginner (interacting with npc and run a command?)

[johnka]

Hello guys, first of all I really don't know much about coding in general and trying to learn the very basics right now, but i had a question about whatever this very small project i have in mind would work or not.

So what i want to do is create a script that runs the command </cancelform> when i right click a friendly NPC, this would be useful for druids in the upcoming wow classic as you can't talk to NPCs in animalforms.

So i would need some api/code that does something when i rightclick an NPC, and well therefor i want to ask if it is at all possible!

Just posting my very limited "psuedo" code, probbably more confusing then helpful but here it is:

if (UnitPlayerControlled("target")) then
{
//DO NOTHING
}

else if (IS UNIT TARGET NPC UNFRIENDLY?)
{
//DO NOTHING
}

else
{
/cancelform
}
end
