[LUA] Spawn Mobs on Item Use Hmm

[DontCareQQ]

Is it possible to like have a item, and when you use it it spawns mobs and a game object on certain locations? like outside every main city?

Would be a challange for lua scripters I guess...

/discuss.

I'm pretty sure that's possible,

I've already come up some solutions in my head,
I'll most likely start doing some testing when I get back home.

Yeah that would be a scripting thing.... you would have to change an item that has a right click ability then change it to do what you want....sorry Im too tired to figure it out... maybe later today I will

[Babbaa]

It's similar as an Item Teleporter,
But you'll simply use Spawn functions instead.

Cool thanks, hope you get things figured out, dying to get this on my server - would be some sweet event then, also - is it possible that they auto-despawn in like 4 hours or something?

[Babbaa]

It's possible to make them despawn after X minutes, Yes.

[DontCareQQ]

Woot that's awesome
